Description

A translational automatic opening anti-theft door

technical field

The invention relates to a wing fan transmission mechanism, in particular to a translational automatic opening anti-theft door.

Background technique

The existing translational automatic opening anti-theft doors all drive the door leaf to translate through the transmission mechanism to realize the opening and closing of the door leaf. The mechanism realizes opening and closing, which has the following disadvantages: 1) When the roller moves on the guide rail, the rolling noise is very large and cannot be overcome and avoided; 2) The roller bearing the weight of the door leaf is prone to jumping during the rolling process, and its stability is poor; 3) The roller wears seriously, which affects the service life, such as the invention patent whose publication number is CN 205532101U and the name is "a kind of translational automatic opening anti-theft door". The other is driven by the motor to drive the screw nut transmission pair. Compared with the above method, although the reliability of the movement has been improved and the noise has been reduced, due to the weight of the door leaf acting on the upper and lower rotating shafts of the moving column At the position, the upper part of the moving column is forced to shift left and right, and the force generated by the bias acts on the upper screw nut transmission pair, which increases the horsepower of the drive motor, and the noise increases as the motor power increases. Long-term use will cause the screw cylinder screw nut pair Wear and tear is serious, life-span is low, reliability is poor, repair and maintenance cost is big, as the patent application that publication number is CN205532101U, the name is called " automatic opening anti-theft door mechanism of translation type ".

detailed description

To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings 1 to 7 and specific implementation methods.

Example 1:

The translational automatic opening anti-theft door adopted in this embodiment includes a door frame and double door leaves arranged in the door frame. The door frame is composed of an upper door frame 2, a left door frame 1, a right door frame 3, and a lower door frame 4. Composition, connected with the door frame through the transmission mechanism, and open or close along the door frame under the drive of the transmission mechanism, linear guide rails 10 are all arranged on the upper door frame 3 and the lower door frame 4, and the transmission mechanism includes a motor driver 16 arranged on the door frame.

Transmission mechanism also comprises hanging block 8, sliding block 9, guide wheel 11 and guide wheel 12, and guide wheel 11 is arranged on the four jiaos in the door frame, is used for changing the direction of wire rope 13. The output shaft 17 of the motor driver 16 is connected with the drive pulley 15 by a belt, and the drive pulley 15 is connected with the guide pulley 12 positioned at the lower end of the left door frame 1, and the guide pulley 12 is connected with the guide pulley 11 positioned at the left door frame 1 through a steel wire rope 13, and positioned at the lower door frame. After the guide wheel 18 of 4, the guide wheel 19 positioned at the right door frame 3, and the guide wheel 20 positioned on the upper door frame 2, are connected with the guide wheel 21 positioned at the left door frame 1 upper end, so that the wire rope 13 forms a loop around the door frame.

A slider 9 moving along the linear guide rail 10 is also fixedly connected to the steel wire rope 13 located at the upper door frame 2, and the lower end of the slider 9 is also connected with a hanging block 8, and the hanging block 8 is also connected with the translation door post 5, and the translation door post 5 is fixed. On the rotating fan 6 , the steel wire rope 13 drives the suspension block 8 to move along the upper door frame under the power of the motor driver 16 , so that the rotating fan 6 is opened or closed. The hanging block 8 in this embodiment is provided with a clamping block, the hanging block 8 and the clamping block are connected by bolts, the steel wire rope 13 is first fixed between the hanging block 8 and the clamping block, and then the bolts are tightened to fix the steel wire rope 13 on the Between the hanging block 8 and the clamping block, the steel wire rope 13 is more stable.

When the motor 16 rotates positively and negatively, it will drive the guide wheel 12 to rotate, and drive the steel wire rope 13 to reciprocate and move parallel to the left on the upper door frame: in the upper door frame 2, the first wire rope 13 passes through the hanging block 8 on the upper end of the left door leaf and the lower end of the right door leaf The hanging blocks 8 are respectively fixed; the second wire rope 13 is respectively fixed by the hanging block 8 at the upper end of the right door leaf and the hanging block 8 at the lower end of the left door leaf. The door leaf 4 does the reciprocating motion of opening or closing.

Example 2:

In this embodiment, the translation gate post 5 is connected with the hanging block 8 through bolts. A rotating shaft 7 is also arranged on the translational door post 5, and the door leaf 6 rotates along the rotating shaft 7 to realize opening or closing. On the wire rope 13 on the right door frame 3, also be connected with wire rope tensioner 14, keep the tightness of wire rope.

In this embodiment, the transmission structure composed of steel wire ropes (chains) is used to solve the balance principle of the heavy weight of the door leaf as follows:

The wire rope 13 in the upper door frame 2, one of them is connected with the A point on the left door leaf 4 hanger block 8, and when the same wire rope is wrapped around the lower door frame from the right door frame, it is connected with the A point of the right door leaf bottom; similarly, the upper door frame 2 Another steel wire rope 13 in the inside is connected with the B point on the right door leaf 4 hanging block 8, and when same wire rope is wrapped around the lower door frame, it is connected with the left door leaf bottom B point. When the weight of the left door leaf causes the upper end A of the left door leaf to be stressed to the left, the steel wire rope 13 transmits the pulling force and acts on the lower end A of the right door leaf; similarly, when the weight of the right door leaf causes the upper end B of the right door leaf to be stressed to the right, The steel wire rope 13 transmits the pulling force and acts on the lower end B of the left door leaf; if the weight of the left and right door leaves is the same, because the steel wire rope is connected in a closed loop through the guide wheel 11 and the guide wheel 12, the tension of the steel wire rope caused by the bias will be the same, and the same force will act The force acting on the upper and lower point A of the left door leaf is the same as the force acting on the upper and lower point B of the right door leaf. Therefore, the left and right door leaves will be in a static state and will not deflect. That is to say, the left and right door leaves are always in a balanced static state regardless of the weight of the door leaf. When the motor drives the wire rope to move, it will drive the left and right door leaves to open and close in parallel.

The sample door experiment proves that the sliding door runs smoothly during the opening and closing process, its driving force is small, the operation is light, the noise is extremely low, and it has the advantages of stable and reliable operation and free opening and closing.

The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present invention. Should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
