Abstract

A support structure comprises a transmission shaft, a clutch linking the transmission shaft, an adapter fixed to the clutch, and a carrier fixed to the adapter or the transmission shaft, so that when power is interrupted, a jig is passed through the adapter to pull the clutch away from the transmission shaft, so the carrier can still be rotated by external force. Therefore, It can avoid a problem that the clutch is stuck and cannot rotate.

FIG. 1 is a schematic structural diagram of a first embodiment of a support structure 1 of the present invention. As shown in FIG. 1 , the supporting structure 1 includes: a transmission shaft 11 , a clutch 12 for connecting the transmission shaft 11 , an adapter 13 for fixing the clutch 12 , and an adapter 13 for fixing the adapter 13 . The carrier 1a.

The transmission shaft 11 is linked to a power source 10 . In this embodiment, the power source 10 is a motor, and its power shaft is connected to the transmission shaft 11 .

Said clutch 12 is manual. In this embodiment, the clutch 12 adopts a two-in-one type of electric type and manual type, so that the clutch can be connected to or separated from the transmission shaft 11 by means of electronic control and/or manual control as required.

The adapter 13 has a placing portion 130 for placing the clutch 12 . In this embodiment, the placing portion 130 is in the shape of a groove, so that the clutch 12 is exposed to the placing portion 130 , so as to facilitate disassembly and assembly and manipulation of the clutch 12 .

The bearing member 1a is a bearing frame, which is used to erect a telescope, a sprinkler, a gun, a lighting lamp or other objects whose direction needs to be adjusted (not shown in the figure).

When in use, the clutch 12 is first connected to the transmission shaft 11 by electronic control or manual control to lock the supporting structure 1 , as shown in FIG. 1 ′, so when the power is normal, the power source 10 is used Rotate the transmission shaft 11 (in the action direction P shown in FIG. 1 ′), so that the clutch 12 rotates along the way, so as to drive the adapter 13 to rotate together with the carrier 1a, so that the target on the carrier 1a can be adjusted position (or direction of action).

On the other hand, when the power is interrupted, the power source 10 cannot rotate the transmission shaft 11 , and at this time, the clutch 12 will block the adapter 13 , so the carrier 1a cannot rotate electrically. Therefore, a fixture (not shown) can be inserted into the adapter 13 through the placing portion 130 of the adapter 13 to manually disengage the clutch 12 from the transmission shaft 11 by manual control. , so that the clutch 12 is in a relaxed state, as shown in Figure 1", at this time, the user can directly drive the carrier 1a together with the adapter 13 and the The clutch 12 rotates together.

FIG. 2 is a schematic structural diagram of a second embodiment of the support structure 2 of the present invention. The difference between this embodiment and the first embodiment lies in the configuration of the adapter 23 and the carrier 1a, and other arrangements are substantially the same, so the same points will not be repeated below.

As shown in FIG. 2 , the adapter 23 is connected to the power shaft of the power source 10 to link the power source 10 , and the bearing member 1 a is fastened to the transmission shaft 11 .

In this embodiment, the transmission shaft 11 protrudes out of the placing portion 230 of the adapter 23 to fasten the carrier 1a.

When in use, the clutch 12 is firstly connected to the transmission shaft 11 by electronic control or manual control, as shown in FIG. Rotate (acting direction P as shown in FIG. 2 ′) the adapter 23 , so that the clutch 12 rotates in the same direction, so as to drive the transmission shaft 11 to rotate together with the carrier 1 a , so that the target on the carrier 1 a can be adjusted position (or direction of action).

When the power is interrupted, the power source 10 cannot rotate the adapter 23, at this time, the clutch 12 will block the transmission shaft 11, so the support frame 1a cannot rotate electrically. Therefore, a jig (not shown) is inserted into the adapter 23 through the placing portion 230 of the adapter 23 to manually disengage the clutch 12 from the transmission shaft 11 by manual control. As shown in Fig. 2", the clutch 12 is in a loose state. At this time, the user can directly drive the carrier 1a and the transmission shaft 11 to rotate together with human power (action direction F as shown in Fig. 2").

Therefore, the supporting structures 1 and 2 of the present invention are mainly based on the configuration of the clutch 12, so that when the power is interrupted, the clutch 12 can be pulled away from the transmission shaft by means of a jig extending into the adapter parts 13, 23 11. The bearing member 1a can still be rotated by external force (such as the action direction F of manpower), so compared with the prior art, the supporting structures 1 and 2 of the present invention can effectively avoid the clutch 12 The problem of stuck and unable to rotate.

In addition, as shown in FIG. 3A , FIG. 3B and FIG. 3C , in the first embodiment and the second embodiment, the transmission shaft 11 has at least one clamping surface S, such as a concave surface, at the engagement position with the clutch 12 . The clutch 12 has at least one clamping portion 120 , such as a convex shape, which is disposed corresponding to the clamping surface S. As shown in FIG. In another embodiment, the clutch 12 has a plurality of locking portions 120 to form a jaw shape. In another embodiment, in order to avoid the self-locking of the mechanism, the clamping surface S is wedge-shaped, and the angle of the concave angle a of the wedge shape is less than 157 degrees.

Specifically, the transmission shaft 11 has three clamping surfaces S at the engagement position with the clutch 12 , which are evenly arranged on the peripheral surface of the transmission shaft 11 , and the clutch 12 corresponds to the three clamping surfaces S There are three clamping parts 120 at the place, so during use, the three clamping parts 120 of the clutch 12 are engaged with the three clamping surfaces S of the transmission shaft 11 by electronic control or manual control. to lock the support structure 2 .

Therefore, through the design of the clamping surface S, the transmission efficiency of the torque can be increased, and the problem of eccentricity of the transmission shaft 11 during rotation can be avoided.

The above embodiments are used to illustrate the principles and effects of the present invention, but not to limit the present invention. Any person skilled in the art can make modifications to the above embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the right of the present invention should be listed in the scope of the patent application described later.
