Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene (PTFE) sheet technology, and specifically to a PTFE sheet with a stable connection. 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] In the process of using polytetrafluoroethylene (PTFE) sheets, multiple PTFE sheets often need to be spliced ​​together. Two PTFE sheets are glued together using quick-setting adhesive to complete the splicing. In this way, the PTFE sheets may break after a period of use, 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 securely connected polytetrafluoroethylene (PTFE) sheet. This solves the problem that, during the use of PTFE sheets, multiple PTFE sheets often need to be spliced ​​together using quick-setting adhesive. However, in this process, the PTFE sheets may break after a period of use, affecting the overall performance.

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

[0006] A securely connected polytetrafluoroethylene (PTFE) sheet includes a PTFE sheet body. Two opposing guide plates are provided on one side of the PTFE sheet body. Multiple evenly distributed elastic plates are provided on the outer end faces of the guide plates. A guide groove for inserting the two guide plates is provided on the other side of the PTFE sheet body. Locking grooves for engaging the elastic plates are provided on the two inner side walls of the guide groove. A receiving groove communicating with the guide groove is provided within the PTFE sheet body. A fastening plate capable of slidingly inserting into the space between the two guide plates within the guide groove is provided within the receiving groove. Guide blocks are symmetrically provided on both sides of the fastening plate.

[0007] As a preferred technical solution of this utility model, the receiving groove is provided with guide grooves on both sides for the displacement of the guide block, and a slide rod that is slidably connected to the guide block is provided in the guide groove, and a compression spring is sleeved on the outside of the slide rod.

[0008] The above technical solution improves the stability of the fastening plate displacement by using guide blocks and guide grooves, and further improves the stability of the fastening plate displacement by using slide rods.

[0009] As a preferred technical solution of this utility model, the fastening plate is provided with a pushing block, and the polytetrafluoroethylene plate body is provided with a pushing groove for the displacement of the pushing block, and the pushing groove is connected to the receiving groove.

[0010] The above technical solution utilizes the setting of the push block to facilitate the worker's drive of the fastening plate to move.

[0011] As a preferred technical solution of this utility model, a fixing groove is provided on the polytetrafluoroethylene plate body between the two guide plates for inserting one end of the fastening plate through the guide groove.

[0012] The above technical solution improves the connection strength between the two polytetrafluoroethylene (PTFE) plates by using the setting of the fixing groove.

[0013] As a preferred technical solution of this utility model, one end of the fastening plate is provided with an inlet portion with a trapezoidal or triangular cross-section.

[0014] The above technical solution utilizes the inlet section to facilitate the insertion of the fastening plate between the two guide plates in the guide groove.

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

[0016] When two PTFE (polytetrafluoroethylene) sheets are joined, the fastening plate is first moved and retracted into the receiving groove by a pushing block, causing the compression spring to deform under pressure. Then, the two guide plates on one PTFE sheet are aligned with the guide groove on the other PTFE sheet and inserted. During insertion, the two guide plates and the elastic plate deform to a certain extent due to the influence of the inner wall of the guide groove. When the two guide plates are inserted to the bottom of the guide groove, they return to their original shape, causing the elastic plate to engage in the locking groove. Then, the pushing block is loosened, causing the compression spring to return to its original shape. Under the force of the compression spring, the fastening plate passes between the two guide plates in the guide groove and is inserted into the fixing groove, ensuring the elastic plate is securely engaged in the locking groove, thus completing the connection of the two PTFE sheets. This invention improves the connection strength and stability between the two PTFE sheets, preventing breakage during use. Attached Figure Description

[0022] Example

[0023] This utility model provides a sturdy polytetrafluoroethylene sheet, for reference. Figure 1-2 As shown, the device includes multiple interconnected polytetrafluoroethylene (PTFE) sheet bodies 1. One side of each PTFE sheet body 1 has two opposing guide plates 2 arranged in a long rectangular structure. The outer end face of each guide plate 2 has multiple evenly distributed elastic plates 3. The elastic plates 3 gradually tilt towards the PTFE sheet body 1 from the end closest to the guide plate 2. Due to the tilting of the elastic plates 3, a guide groove 8 is formed on the other side of the PTFE sheet body 1 for the two guide plates 2 to be inserted. Locks are formed on the two inner side walls of the guide groove 8 for the elastic plates 3 to engage. The locking groove, through the setting of the locking groove and the elastic plate 3, improves the tightness of the connection between the two polytetrafluoroethylene plate bodies 1. The polytetrafluoroethylene plate body 1 has a receiving groove 9 that communicates with the guide groove 8. The receiving groove 9 has a fastening plate 4 that can be slidably inserted into the guide groove 8 between the two guide plates 2. The setting of the fastening plate 4 improves the tightness of the elastic plate 3 on the guide plate 2 being engaged in the locking groove, and prevents the elastic plate 3 from detaching from the connection with the locking groove. The fastening plate 4 has symmetrical trapezoidal guide blocks 12 on both sides.

[0024] The receiving groove 9 has symmetrical guide grooves on both sides for the displacement of the guide block 12. The arrangement of the guide block 12 and the guide groove improves the stability of the displacement of the fastening plate 4. The guide groove is provided with a slide rod 10 that is slidably connected to the guide block 12. The arrangement of the slide rod 10 further improves the stability of the displacement of the fastening plate 4. A compression spring 11 is sleeved on the outside of the slide rod 10. One end of the compression spring 11 is connected to the inner side wall of the guide groove, and the other end of the compression spring 11 is connected to the guide block 12.

[0025] The fastening plate 4 is provided with a pushing block 6, and the polytetrafluoroethylene plate body 1 is provided with a pushing groove 7 for the pushing block 6 to move. The pushing groove 7 is connected to the receiving groove 9. The setting of the pushing block 6 makes it convenient for the staff to drive the fastening plate 4 to move.

[0026] Among them, the polytetrafluoroethylene plate body 1 between the two guide plates 2 is provided with a fixing groove for inserting one end of the fastening plate 4 through the guide groove 8. The setting of the fixing groove improves the connection strength and stability between the two polytetrafluoroethylene plate bodies 1.

[0027] The fastening plate 4 has an inlet portion 5 at one end with a trapezoidal or triangular cross-section. The inlet portion 5 facilitates the fastening plate 4 to be inserted between the two guide plates 2 in the guide groove 8.

[0028] The working principle of this utility model is as follows:

[0029] When the two polytetrafluoroethylene (PTFE) sheet bodies 1 are spliced, the fastening plate 4 is first moved and retracted into the receiving groove 9 by the pushing block 6, so that the compression spring 11 is compressed and deformed. Then, the two guide plates 2 on one PTFE sheet body 1 are aligned with the guide groove 8 on the other PTFE sheet body 1 and inserted. During the insertion process, the two guide plates 2 and the elastic plate 3 are deformed to a certain extent by the influence of the inner side wall of the guide groove 8. When the two guide plates 2 are inserted to the bottom of the guide groove 8, the two guide plates 2 and the elastic plate 3 recover their deformation, so that the elastic plate 3 is locked into the locking groove. Then, the pushing block 6 is loosened so that the compression spring 11 recovers its deformation, so that the fastening plate 4 passes through the two guide plates 2 in the guide groove 8 and is inserted into the fixing groove under the action of the compression spring 11, so that the elastic plate 3 is firmly locked into the locking groove for engagement, thus completing the connection of the two PTFE sheet bodies 1. This invention improves the connection strength and stability between the two polytetrafluoroethylene (PTFE) plate bodies 1, and avoids the breakage of the two PTFE plate bodies 1 during use.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
