Description

An Improved Circuit Board Fixture

technical field

The utility model relates to the technical field of circuit board manufacturing tools, in particular to an improved circuit board fixture.

Background technique

At present, the existing circuit board fixtures on the market are generally smaller in size, so that the work of circuit board production can be carried out more lightly. Moreover, the clamping position of the circuit board is generally inside the fixture. However, when making larger circuit boards, the clamps are often too small to support the circuit boards for production work, which leads to certain limitations of the existing circuit board clamps and cannot be used more widely.

Utility model content

The utility model provides an improved circuit board fixture with simple structure, convenient use, smaller volume and wider application range.

The utility model is achieved through the following technical solutions:

An improved circuit board fixture, comprising a frame body and a movable bar, the left and right ends of the front side of the frame body are respectively provided with a circular track, and the two ends of the movable bar are respectively provided with a circular channel hole, the movable bar is sleeved on the circular track, and slides up and down along the circular track, the front side of the lower frame of the frame is provided with a first trapezoidal locking tooth, and the movable bar A second trapezoidal locking tooth is provided on the lower surface, and the front side of the first trapezoidal locking tooth and the front side of the second trapezoidal locking tooth are located in the same vertical plane.

The frame body is a hollow rectangular structure inside.

Threaded holes are provided on the left and right sides of the movable bar, and are fixed on the circular track with locking screws.

The first trapezoidal locking teeth and the second trapezoidal locking teeth are arranged corresponding to each other.

The circular track is welded to the frame body through connecting rods.

The beneficial effects brought by the utility model are:

In the utility model, the improved circuit board fixture cabinet includes a frame body and a movable bar, and the simplest structure of the frame body and the movable bar can make the fixture easier to hold the circuit board. The improved circuit board fixture has the advantages of convenient use, simple structure and wider application range.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

As an embodiment of the improved circuit board fixture of the present utility model, as shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, it includes a frame body 1 and a movable bar 2, the left side, the front side of the frame body 1, A circular track 3 is respectively provided at the right two ends, and a circular through hole 4 is respectively provided at the two ends of the movable bar 2, and the movable bar 2 is sleeved on the circular track 3, and along the The circular track 3 slides up and down, and the structure can make the sliding of the movable bar 2 more flexible. The front side of the lower frame of the frame body 1 is provided with a first trapezoidal latch 5, and the lower part of the movable bar 2 The surface is provided with a second trapezoidal locking tooth 6, and the front side of the first trapezoidal locking tooth 5 and the front side of the second trapezoidal locking tooth 6 are located in the same vertical plane. This structure can support the circuit board more powerfully.

In this embodiment, the frame body 1 is a hollow rectangular structure, and the hollow structure can better save materials.

In this embodiment, the left and right sides of the movable strip 2 are provided with threaded holes 7, and are fixed on the circular track 3 with locking screws 8. This structure enables the movable strip 2 to It is better fixed on the circular track 3 so as not to loosen.

In this embodiment, the first trapezoidal locking teeth 5 and the second trapezoidal locking teeth 6 are arranged corresponding to each other, and the corresponding structure makes the clamp more stable when clamping the circuit board.

In this embodiment, the circular track 3 is welded to the frame body 1 through the connecting rod 9 , and the welded structure enables the circular track 3 to be more firmly connected to the frame body 1 .
