Description

Technical Field

[0001] This utility model relates to the field of conductive foam technology, specifically an assembly device for conductive foam. Background Technology

[0002] Conductive foam is a composite material made by wrapping conductive cloth, metal plating (such as nickel or copper), or adding conductive particles on a flame-retardant sponge or polymer foam substrate. Conductive foam constructs a three-dimensional conductive path through conductive layers (such as conductive cloth or metal plating) to achieve the reflection and absorption of electromagnetic waves. Due to its conductivity, buffering and environmental adaptability, conductive foam has become an indispensable electromagnetic shielding material in the fields of electronics, automobiles, and medical care.

[0003] Regarding the above and existing related technologies: when installing conductive foam, most conductive foam is glued to other devices, and some conductive foam is also fixed with bolts. In actual use, glue bonding may delaminate due to its own characteristics under temperature changes, while bolt fixing is prone to excessive force during installation, leading to damage to the foam; therefore, an assembly device for conductive foam is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The assembly device for conductive foam of this utility model includes a foam board and a fixing device. The fixing device is disposed on the surface of the foam board. The fixing device includes a fixing frame, which is sleeved on the surface of the foam board. Inserts are inserted into the inner surfaces of the four corners of the fixing frame. Two moving blocks are slidably connected to the inner walls of the inserts. A locking block is fixedly connected to the side wall of the moving block. Pushing the inserts allows them to be inserted into the inner surface of the fixing frame. Then pushing the moving blocks causes them to slide the locking blocks. The locking blocks move to the bottom of the installation position. By setting the fixing frame, inserts, moving blocks and locking blocks, the position of the foam board can be restricted to a certain extent.

[0006] Preferably, a push post is inserted into the inner surface of the insert post, and the push post will squeeze the moving block. By setting the push post, the position of the moving block can be restricted.

[0007] Preferably, three anti-slip sleeves are fixedly connected to the surface of the push post, and a storage groove is opened on the surface of the insertion post. The push post and the anti-slip sleeves are inserted into the inner surface of the storage groove of the insertion post. The anti-slip sleeves are rubber sleeves that are pressed against the inner surface of the insertion post. By setting the anti-slip sleeves, the movement of the push post can be reduced.

[0008] Preferably, the inner surface of the fixing frame is fixedly connected with multiple locking strips. The locking strips are inserted into the inner surface of the cotton board. When the cotton board moves, the cotton board will press against the surface of the locking strips. The locking strips can restrict the position of the cotton board.

[0009] Preferably, a slot is provided on the surface of the cotton board near the card strip, and the card strip is inserted into the inner surface of the slot of the cotton board. When the cotton board moves, the cotton board is fitted onto the surface of the card strip through the slot, and the slot can be used to store the card strip.

[0010] Preferably, the upper surface of the fixing frame is provided with multiple limiting devices. Each limiting device includes a support column, the surface of which is threaded to the inner wall of the fixing frame. A rotating block is rotatably connected to the surface of the support column, and a soft pad is fixedly connected to the bottom end of the rotating block. The soft pad is located on the upper surface of the cotton board. The rotating block drives the soft pad to rotate, and the soft pad is pressed against the upper surface of the cotton board. By setting the support column, rotating block, and soft pad, the position of the cotton board can be limited.

[0011] Preferably, the rotating block has a rotating hole on its surface, and the inner wall of the rotating hole is rotatably connected to the surface of the support column. When the rotating block rotates, it rotates on the surface of the support column through the rotating hole. The rotating hole facilitates the rotation of the rotating block.

[0012] The advantages of this utility model are:

[0013] 1. In this utility model, when installing the cotton board, the cotton board is pushed so that the panel moves towards the fixing frame. The cotton board will then fit onto the surface of the clip through the slot. The fixing frame is then pushed so that it fits into the installation position. The insert post is then pushed so that it is inserted into the inner surface of the fixing frame. The push post is then pushed so that it moves the anti-slip sleeve. The anti-slip sleeve is pressed against the inner surface of the storage groove. The push post will press against the moving block so that it moves. The moving block slides on the inner surface of the insert post. When the moving block moves, it will cause the clip to slide. The clip is pressed against the bottom of the installation position. By setting the entire device, the cotton board can be installed, while reducing the use of glue and avoiding the situation where the cotton board lifts due to glue delamination. It can also reduce the situation where the cotton board is damaged during bolt installation.

[0014] 2. When using the fixing frame, the support column is rotated to the inner surface of the fixing frame, and then the rotating block is pushed to make the rotating block drive the soft pad to rotate. The rotating block rotates on the surface of the support column through the rotating hole. When the soft pad rotates, it will rotate to the surface of the cotton board and the soft pad will be pressed against the surface of the cotton board. By setting the entire device, the situation of the panel falling off can be reduced. Attached Figure Description

The inserts 22 are pushed to insert into the inner surface of the fixing frame 21. The moving blocks 23 are then pushed to move the locking blocks 24 to the bottom of the installation position. By setting the fixing frame 21, inserts 22, moving blocks 23 and locking blocks 24, the position of the foam board 1 can be restricted to a certain extent.

[0024] A push post 25 is inserted into the inner surface of the insertion post 22. During operation, the push post 25 is pushed to insert into the inner surface of the insertion post 22. The push post 25 will squeeze the moving block 23. By setting the push post 25, the position of the moving block 23 can be restricted.

[0025] Three anti-slip sleeves 26 are fixedly connected to the surface of the push post 25. A storage groove 27 is opened on the surface of the insertion post 22.

During operation, the push post 25 will drive the anti-slip sleeves 26 to move. The anti-slip sleeves 26 are pressed against the inner surface of the insertion post 22. By setting the anti-slip sleeves 26, the random movement of the push post 25 can be reduced.

[0026] The inner surface of the fixing frame 21 is fixedly connected with a plurality of locking strips 28, which are inserted into the inner surface of the cotton board 1. During operation, the cotton board 1 is pressed against the surface of the locking strips 28, and the locking strips 28 can restrict the position of the cotton board 1.

[0027] A slot 29 is provided on the surface of the cotton board 1 near the card strip 28, and the card strip 28 is inserted into the inner surface of the slot 29 of the cotton board 1. During operation, the cotton board 1 is fitted onto the surface of the card strip 28 through the slot 29, and the slot 29 can accommodate the card strip 28.

[0028] The upper surface of the fixed frame 21 is provided with multiple limiting devices 3. Each limiting device 3 includes a support column 31.
