Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene (PTFE) sheet technology, and specifically to a PTFE sheet that is stably assembled. Background Technology

[0002] Polytetrafluoroethylene (PTFE) sheets (also called PTFE sheets, Teflon sheets, or polytetrafluoroethylene sheets) come in two types: molded and machined. Molded sheets are made by molding PTFE resin at room temperature, followed by sintering and cooling. Machined PTFE sheets are made by pressing PTFE resin into a compact, sintering, and then rotary cutting. These products have a wide range of applications.

[0003] Currently, PTFE sheets often need to be spliced ​​together during use. However, quick-setting adhesive is used for splicing, and after a period of use, the joints of the PTFE sheets may break, affecting the performance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a stable and sturdy PTFE sheet. This solves the problem that PTFE sheets often need to be spliced ​​together during use, but quick-setting adhesive is used for splicing. However, after a period of use, the joints of the PTFE sheets in this way will break, affecting the performance of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sturdy PTFE sheet includes a PTFE sheet body. One side of the PTFE sheet body has an overlap plate. Each of the four corners of the bottom end face of the overlap plate has a guide post. One side of each guide post has a fastening plate. The other side of the PTFE sheet body has an overlap groove for the overlap plate to engage. The bottom of the overlap groove has an inlet groove on the PTFE sheet body for the guide post and the fastening plate to insert into. Multiple inlet grooves are provided on the PTFE sheet body between the inlet grooves. A locking rod is slidably installed in each of the installation grooves.

[0007] As a preferred technical solution of this utility model, a fastening groove is provided in the polytetrafluoroethylene plate body on one side of the inlet groove for the fastening plate to be inserted after the guide post is displaced.

[0008] The above technical solution improves the connection strength of the two polytetrafluoroethylene (PTFE) plates by using fastening plates and fastening grooves.

[0009] As a preferred technical solution of this utility model, a locking groove for inserting a locking rod is provided on the bottom end face of the overlapping plate.

[0010] The above technical solution utilizes the locking groove and locking rod to limit and fix the connection between the two polytetrafluoroethylene (PTFE) plates.

[0011] As a preferred technical solution of this utility model, a limiting groove communicating with the mounting groove is provided in the polytetrafluoroethylene plate body, and a limiting plate connected to the locking rod is provided in the limiting groove.

[0012] By using the above technical solution, the locking rod is prevented from disengaging from the mounting groove by the setting of the limiting groove and the limiting plate.

[0013] As a preferred embodiment of this utility model, a compression spring is provided in the limiting groove below the limiting plate.

[0014] The above technical solution utilizes the spring force generated by the compression spring to improve the tightness of the locking rod inserted into the locking groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] During installation, firstly, the guide post and fastening plate on one PTFE sheet are aligned and inserted into the guide groove in the other PTFE sheet. This causes the overlapping plate to press the locking rod back into the mounting groove. Then, one PTFE sheet is displaced, causing the guide post and fastening plate in the guide groove to shift, allowing the fastening plate to insert into the fastening groove. Simultaneously, the compression spring returns to its original deformation. Under the elastic force generated by the spring's return to its original deformation, the locking rod in the mounting groove pops out and engages with the locking groove, thus completing the butt joint assembly of the two PTFE sheets. This invention improves the connection strength between the butt joints of two PTFE sheets, preventing breakage at the joint where glue is used for connection. Attached Figure Description

[0023] Example

[0024] This utility model provides a stable and assembled polytetrafluoroethylene sheet, for reference. Figure 1-3 As shown, the device includes a polytetrafluoroethylene (PTFE) sheet body 1. One side of the PTFE sheet body 1 is provided with an integrally formed overlapping plate 2. Through the setting of the overlapping plate 2, the locking rod 10 can be squeezed back into the mounting groove 7. The four corners of the bottom end face of the overlapping plate 2 are provided with guide posts 3. One side of the guide post 3 is provided with a fastening plate 8. The fastening plate 8 and the guide post 3 are integrally formed with an L-shaped structure. The other side of the PTFE sheet body 1 is provided with an overlapping groove 4 for the overlapping plate 2 to be snapped into. The bottom of the overlapping groove 4 is provided with an inlet groove 5 on the PTFE sheet body 1 for the guide post 3 and the fastening plate 8 to be inserted. The inlet groove 5 corresponds to the guide post 3 one by one. Multiple mounting grooves 7 are provided on the PTFE sheet body 1 between the multiple inlet grooves 5. The locking rod 10 is slidably installed in the mounting groove 7.

[0025] The polytetrafluoroethylene (PTFE) plate body 1 on one side of the inlet groove 5 has a fastening groove 6 for inserting the fastening plate 8 after the guide post 3 is displaced. The fastening groove 6 is connected to the inlet groove 5. The fastening plate 8 and the fastening groove 6 improve the connection strength between the two PTFE plate bodies 1.

[0026] The bottom end face of the overlapping plate 2 is provided with a locking groove 9 for the locking rod 10 to be inserted. The locking groove 9 and the locking rod 10 are provided to limit and fix the connection between the two polytetrafluoroethylene plate bodies 1, and prevent the fastening plate 8 from detaching from the connection with the fastening groove 6.

[0027] The polytetrafluoroethylene (PTFE) plate body 1 has a limiting groove 12 that communicates with the mounting groove 7. The limiting groove 12 allows the limiting plate 11 to move. The limiting groove 12 contains a limiting plate 11 that connects to the bottom of the locking rod 10. The limiting plate 11 prevents the locking rod 10 from disengaging from the mounting groove 7.

[0028] Furthermore, a compression spring 13 is provided in the limiting groove 12, located below the limiting plate 11. One end of the compression spring 13 is connected to the bottom end face of the limiting plate 11, and the other end of the compression spring 13 is connected to the bottom end face of the limiting groove 12. The elastic force generated by the compression spring 13 improves the tightness of the locking rod 10 inserted into the locking groove 9.

[0029] The working principle of this utility model is as follows:

[0030] During installation, firstly, the guide post 3 and fastening plate 8 on one PTFE plate body 1 are aligned and inserted with the guide groove 5 in the other PTFE plate body 1. This causes the overlapping plate 2 to press the locking rod 10 back into the mounting groove 7. Then, one of the PTFE plate bodies 1 is moved, causing the guide post 3 and fastening plate 8 in the guide groove 5 to move, so that the fastening plate 8 is inserted into the fastening groove 6. At the same time, the compression spring 13 returns to its original deformation. Under the elastic force generated by the return of the compression spring 13 to its original deformation, the locking rod 10 in the mounting groove 7 pops out and snaps into the locking groove 9, thus completing the butt joint assembly of the two PTFE plate bodies 1. This utility model improves the connection strength of the butt joint assembly between the two PTFE plate bodies 1 and avoids the later breakage of the PTFE plate bodies 1 connected by glue.
