Embodiment 1

[0047] See Figure 6 , the end-to-end gasket of this embodiment includes: an elastic net tube 3, a glass fiber cloth tube 5 sleeved on the elastic net tube 3; a high temperature resistant yarn or metal wire or a resistant High-temperature elastic thread or spring 14, the glass fiber cloth at the head end of the glass fiber cloth tube 5 is folded toward its inner hole to form a female head 51 with a double layer, and the tail end of the glass fiber cloth pipe is a male head 52; After connecting the high temperature resistant yarn or metal wire or high temperature resistant elastic wire or spring 14 end to end, insert the male connector 52 into the female connector 51 . The pad joint with this structure is easy to operate and is beneficial to improve production efficiency. The change of the pipe diameter at the joint of the gasket is small, so the sealing performance of the gasket is better.

Embodiment 2

[0052] Compared with the above-mentioned embodiment 1, the structure of the head-to-tail connection type gasket in this embodiment of this embodiment has the following modifications:

[0053] The glass fiber cloths at the first and last ends of the glass fiber cloth pipe 5 are folded towards the respective inner holes to form double-layer parts at the first and last ends respectively, (the double-layer parts may be at the first and last ends of the elastic network pipe. outside the two ends, or the ends of the elastic mesh tube are in the corresponding double-layer parts), the two ends of the staple 8 pass through the double-layer parts of the first and last ends respectively and connect the first and last ends (The preferred solution is: the two ends of the staple 8 are also connected to the first and last ends of the elastic network pipe 3 at the same time, so as to ensure that the joint has corresponding elasticity, so as to improve the sealing of the gasket and the quality ...

Embodiment 3

[0056] Compared with the above-mentioned embodiment 2, there are the following modifications in the structure of the head-to-tail connection type gasket in this embodiment:

[0057] Such as Figure 11 , the glass fiber cloths at the first and last ends of the fiberglass cloth pipe 5 are folded toward their respective inner holes to form double-layer parts at the first and last ends respectively, (the double-layer parts may be at the first and second ends of the elastic network pipe Outside the two ends of the tail, or the end of the elastic net tube is in the corresponding double-layer part), a pair of metal buckles 9 are used to connect the double-layer parts at the two ends of the head and tail.

[0058] Such as Figure 12 , the metal buckle 9 is a scroll spring buckle, and the inner and outer ends of the buckle have hook parts; the outer end hook part 91 of the buckle passes through the double-layer part and is embedded in the outer layer of glass fiber In the cloth, the ...

Abstract

The invention relates to an end-to-end connected lining cushion. The end-to-end connected lining cushion comprises a glass fiber fabric tube and an elastic net pipe which wholly penetrates through the glass fiber fabric tube, wherein glass fiber fabrics at the head end and the tail end of the glass fiber fabric tube are turned towards inner holes of the glass fiber fabrics to respectively form dual-layer parts at the head end and the tail end; the end openings of the dual-layer parts at the head end and the tail end are directly sewn and connected by a high-temperature-resistant yarn or metal wire; during the sewing process, the end openings of the dual-layer parts at the head end and the tail end of the glass fiber fabric tube are aligned, and the high-temperature-resistant yarn or metal wire is wound around the adjacent edges of the two aligned end openings for a circle to sew the end openings. The end openings of the dual-layer parts at the two ends are sewed and connected, edges of the glass fiber fabrics can be prevented from loosening, and connection strength can also be improved. The problem that tube diameters are not consistent caused when the head end and the tail end are connected in a sleeving way is also prevented, the tube diameter at a joint is consistent to the tube diameters of other parts, and a product is attractive in appearance and good in sealing property.

Description

technical field [0001] The invention relates to a head-to-tail connection gasket and a production method thereof, in particular to a sealing gasket arranged on an oven door. Background technique [0002] Countries around the world have used ovens for a long time, and the semi-airtight seal between the oven and the oven door is a consumable accessory. Usually, the oven door liner is a strip-shaped glass fiber cloth tube with stainless steel wire as the skeleton. It is placed at the junction of the furnace body and the furnace door through the positioning hook. For example: [0003] Chinese patent document CN101438719B discloses a liner with a head-to-tail connection structure, such as figure 1 , which includes a female head and a male head, the male head protrudes into the female head; a spring clip is worn on the adjacent side wall of the female head and the male head. [0004] Chinese patent literature publication number CN1255187 and U.S. Patent US7104546 disclose a tub...
