Description

Technical Field

[0001] The utility model relates to the technical field of PCB board testing, in particular to a testing device for elevator control boards. Background Technique

[0002] The control board of an elevator is a PCB board. The PCB placement board, also known as a printed circuit board, is a carrier for the electrical connection of electronic components. During the manufacturing process of the PCB placement board, it is necessary to test its physical strength.

[0003] In the prior art, a PCB board strength testing device with the application number CN202223290684.2 is disclosed. In this document, the fixing of the PCB board is achieved through two L-shaped fixing seats. The method of adjusting the two L-shaped fixing seats is relatively cumbersome and not simple enough. Therefore, the testing device in this document can be improved to simplify the fixing method of the PCB board. Content of the Utility Model

[0004] The purpose of the utility model is to provide a testing device for elevator control boards to solve the above problems.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A testing device for elevator control boards includes a base and a testing head. A bracket is fixed on the base, and an electric push rod is installed on the bracket. The end of the electric push rod is fixed with the testing head. A first fixing block is fixed on the bracket, and a first round rod and a second round rod are slidably connected to the first fixing block. The ends of the first round rod and the second round rod are fixed with L-shaped seats. An end block is fixed on the first round rod, and a spring is sleeved on the first round rod. A second fixing block is fixed on the bracket, and the second fixing block is cooperated with the L-shaped seat through a cooperating part to fix the PCB board.

[0007] Preferably, the cooperating part includes a screw rod threadedly connected to the second fixing block. The second fixing block is also slidably connected with a corresponding rod, and a square block is fixed at the end of the corresponding rod. The square block is rotatably connected to the screw rod, and a pressing plate is fixed on the square block.

[0008] Preferably, the pressing plate is provided with scale lines to determine the position of the PCB board on the pressing plate and the L-shaped seat.

[0009] Preferably, a rotating rod is threadedly connected to the L-shaped seat, and a pressing block is rotatably connected to the end of the rotating rod.

[0010] Preferably, an elastic rubber gasket protrudes from the part of the pressing block in contact with the PCB board.

[0011] Preferably, rubber anti-slip protrusions are provided on the upper surface of the pressing plate in contact with the PCB board.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0013] 1. By rotating the screw rod, the position of the square block can be changed, and thus, with the cooperation of the spring, the position of the L-shaped seat will change accordingly. However, the PCB board on the L-shaped seat and the pressing plate will not lose its fixation, that is, by rotating the screw rod, the horizontal position of the PCB board can be changed, which is convenient for the test head to align with the location to be tested, and the operation is relatively simple and convenient.

[0014] 2. With the cooperation of the spring, when the screw rod rotates to change the position of the square block, the square block and the L-shaped seat clamp and fix the PCB board, and there will be no phenomenon that the PCB board is damaged due to excessive clamping force. Therefore, this clamping device can better exert the clamping effect on the PCB board without worrying about whether the square block is displaced too much to damage the side of the PCB.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1:

[0021] The present utility model provides a technical solution. Please refer to Figure 1-2 :

[0022] A test device for an elevator control board, including a base 1 and a test head 4. A bracket 2 is fixed on the base 1, and an electric push rod 3 is installed on the bracket 2. The end of the electric push rod 3 is fixed with the test head 4. This is a direct reference to the prior art and will not be elaborated here. A first fixing block 5 is fixed on the bracket 2, and a first round rod 6 and a second round rod 9 are slidably connected to the first fixing block 5. The ends of the first round rod 6 and the second round rod 9 are fixed with an L-shaped seat 10. An end block 7 is fixed on the first round rod 6, and a spring 8 is sleeved on the first round rod 6. A second fixing block 13 is fixed on the bracket 2, and the second fixing block 13 is matched with the L-shaped seat 10 through a matching part to fix the PCB board. A rotating rod 11 is threadedly connected to the L-shaped seat 10, and a pressing block 12 is rotatably connected to the end of the rotating rod 11. An elastic rubber gasket protrudes on the part of the pressing block 12 in contact with the PCB board.

[0023] Embodiment 2:

[0024] Basically the same as the technical solution of Embodiment 1, the difference is that, as Figure 2 shown, the matching part includes a screw rod 14 threadedly connected to the second fixing block 13. The second fixing block 13 is also slidably connected with a corresponding rod 15, and a square block 16 is fixed to the end of the corresponding rod 15. The square block 16 is rotatably connected to the screw rod 14, and a resisting plate 17 is fixed on the square block 16. Scale lines 18 are provided on the resisting plate 17 to determine the position of the PCB board on the resisting plate 17 and the L-shaped seat 10. Rubber anti-slip protrusions are provided on the upper surface of the resisting plate 17 in contact with the PCB board. The PCB board abuts against the bending part below the resisting plate 17 and the L-shaped seat 10, and in the cooperation of the square block 16 and the L-shaped seat 10, it abuts against the side surface of the PCB board, thereby realizing the clamping and fixing effect on the PCB board. With the cooperation of the spring 8, when the screw rod 14 rotates to change the position of the square block 16, the square block 16 and the L-shaped seat 10 clamp and fix the PCB board, and the phenomenon that the PCB board is damaged due to excessive clamping force will not occur.

[0025] In summary, in this embodiment, push the end block 7 away from the first fixing block 5, and then the PCB board can be placed on the resisting plate 17 and the L-shaped seat 10, and release the thrust on the end block 7. Under the elastic force of the spring 8, the resisting plate 17 and the L-shaped seat 10 cooperate to abut against the side surface of the PCB board, thereby clamping and fixing it. Then the rotating rod 11 can be rotated to make the pressing block 12 clamp and fix the PCB board in the up and down direction. At this time, the PCB board is fixed on the resisting plate 17 and the L-shaped seat 10. By rotating the screw rod 14, the horizontal position of the resisting plate 17 can be changed, thereby changing the horizontal position of the PCB board.

[0026] The foregoing description of the embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather should be accorded the widest scope consistent with the principles and novel features disclosed herein.
