Abstract
Description
Technical Field
[0001] This utility model relates to the field of polytetrafluoroethylene (PTFE) technology, specifically to an improved PTFE sheet. Background Technology
[0002] Polytetrafluoroethylene (PTFE) sheets (also called PTFE sheets, Teflon sheets, or PTFE plates) 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 PTFE sheets in this way tend to break after a period of use, affecting their performance. For example, Chinese patent document CN221610345U, published on August 27, 2024, discloses a utility model patent for "a PTFE sheet with an assembly structure," which includes several PTFE sheet bodies. Each PTFE sheet body has grooves on both the front and rear ends of one side, and a connecting component adapted to the grooves is provided on the other side. This solution connects two PTFE sheet bodies by inserting the connecting component on one side of one PTFE sheet body into the groove on the opposite side of another PTFE sheet body. However, when the PTFE sheet body is damaged, this solution is inconvenient for disassembly and replacement, greatly reducing its practicality. Utility Model Content

A displacement plate located in the slot is screwed onto both the positive and negative threads of the bidirectional screw. One end of the displacement plate extends to the outside of the slot and is provided with a snap-fit plate perpendicular to it.
[0007] The polytetrafluoroethylene sheet body has an assembly groove on the other side for the assembly block to be inserted. The two inner walls of the assembly groove are provided with insertion grooves for the snap-fit plate to be inserted. The inner wall of the insertion groove is provided with snap-fit grooves for the snap-fit plate to snap into place after displacement.
[0008] As a further embodiment of this utility model, the outer wall of the assembly block is provided with a displacement groove that allows the two displacement plates to move.

[0024] Example
[0025] refer to Figures 1-5 An improved polytetrafluoroethylene (PTFE) sheet includes a PTFE sheet body 1. Assembly blocks 11 are symmetrically arranged on one side of the PTFE sheet body 1. A slot 111 is formed within each assembly block 11. A bidirectional screw 112 is disposed within the slot 111. One end of the bidirectional screw 112 is rotatably connected to a movable base 113 disposed on the inner wall of the slot 111. The other end of the bidirectional screw 112 is provided with a drive rod 114 extending to the outside of the assembly block 11. Both the positive and negative threads are screwed with displacement plates 115 located in the empty slot 111. One end of the displacement plate 115 extends to the outside of the empty slot 111 and is provided with a snap-fit plate 116 perpendicular to it. The other side of the polytetrafluoroethylene plate body 1 is provided with an assembly slot 12 for the assembly block 11 to be inserted. Both inner side walls of the assembly slot 12 are provided with insertion slots 121 for the snap-fit plate 116 to be inserted. The inner side wall of the insertion slot 121 is provided with a snap-fit slot 122 for the snap-fit plate 116 to be snapped after displacement.
[0026] Furthermore, the outer wall of the assembly block 11 is provided with a displacement groove 117 that allows the two displacement plates 115 to move. By setting the displacement groove 117, the displacement of the displacement plates 115 can be limited.
[0027] Furthermore, a receiving groove 123 is provided on one side of the polytetrafluoroethylene plate body 1 to accommodate the drive rod 114, and the receiving groove 123 is connected to the assembly groove 12.
[0028] Furthermore, the end of the drive rod 114 away from the bidirectional screw 112 is provided with a rotating handle 118.
[0029] Furthermore, a plurality of first reinforcing blocks 13 are evenly distributed on the polytetrafluoroethylene plate body 1 between the two assembly blocks 11, and a plurality of second reinforcing blocks 14 are evenly distributed on the polytetrafluoroethylene plate body 1 between the two assembly grooves 12, and the second reinforcing blocks 14 are staggered from the first reinforcing blocks 13.
[0030] Furthermore, one side of the polytetrafluoroethylene (PTFE) plate body 1 is provided with a second reinforcing groove 15 for the second reinforcing block 14 to be inserted, and the other side of the PTFE plate body 1 is provided with a first reinforcing groove 16 for the first reinforcing block 13 to be inserted. By combining the first reinforcing block 13 and the first reinforcing groove 16 with the second reinforcing block 14 and the second reinforcing groove 15, the connection strength between two adjacent PTFE plate bodies 1 is further strengthened.
[0031] Furthermore, the displacement plate 115 and the snap-fit plate 116 are integrally formed L-shaped structures.
[0032] Preferably, in the initial state, both displacement plates 115 are located at the ends of the displacement groove 117 that are close to each other, so that when the two adjacent polytetrafluoroethylene plate bodies 1 are installed, the snap-fit plate 116 can be inserted into the insertion groove 121.
[0033] The working principle of this utility model:
[0034] During installation, firstly, the assembly block 11 in the polytetrafluoroethylene (PTFE) sheet body 1 is aligned with the assembly groove 12 of the adjacent PTFE sheet body 1 and inserted. At the same time, the snap-fit plate 116 is inserted into the insertion groove 121. The first reinforcing block 13 and the second reinforcing block 14 are inserted into the first reinforcing groove 16 and the second reinforcing groove 15 respectively, thereby initially connecting the two adjacent PTFE sheet bodies 1. Then, the rotating handle 118 is rotated to drive the bidirectional screw 112 to rotate. The two displacement plates 115 move in opposite directions on the bidirectional screw 112 and drive the snap-fit plate 116 to snap into the snap-fit groove 122, thereby snapping and locking the two PTFE sheet bodies 1 together.
[0035] During disassembly, rotating the handle 118 drives the bidirectional screw 112 to rotate, and the two displacement plates 115 move towards each other on the bidirectional screw 112, causing the snap-fit plate 116 to disengage from the snap-fit groove 122, thus disassembling and separating the two polytetrafluoroethylene plate bodies 1. The disassembly process is quick and convenient.
[0036] 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.
[0037] 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.
