Description

Technical Field

[0002] The wire mesh skeleton plastic composite pipe is an improved new type of steel skeleton plastic composite pipe, which is also called SRTP pipe. This new type of pipeline is made of high-strength plasticized wire mesh skeleton and thermoplastic polyethylene as raw materials. The wire winding mesh is used as the skeleton reinforcement of the polyethylene plastic pipe. It takes high-density polyethylene (HDPE) as the matrix and adopts high-performance HDPE modified adhesive resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, so that it has excellent composite effect. Because the high-strength steel wire reinforcement is coated in continuous thermoplastic plastic, this composite pipe overcomes the shortcomings of steel pipe and plastic pipe respectively, while maintaining their respective advantages.

[0003] For example, publication number CN216131537U discloses a wire mesh skeleton tube, which includes a tube body, which is composed of two tube bodies and a connecting tube, the connecting tube is tightly sleeved at the connection of the two sections of the tube body, the connecting tube is made of elastic material, both ends of the connecting tube are provided with notches, a locking groove is provided on one side wall of the notch, a locking plate inserted into the locking groove is fixed on the other side wall of the notch, a stop groove is provided on the inner side wall of the locking groove, and a stop block is provided on the locking plate to be inserted into the stop groove. The beneficial effect of the utility model is that after the two tube bodies are inserted into the connecting tube and the two tube bodies are pressed against each other, a gripping force is applied to the end of the connecting tube to shrink the tube mouth so as to clamp the two tube bodies, and the tube mouth, under the cooperation of the stop block and the stop groove, offsets the expansion force of the tube body, avoids the expansion of the tube mouth of the connecting tube, and the installation is fast and firm, which speeds up the installation progress of the skeleton tube.

[0031] As a technical optimization scheme of the utility model, by setting a pull plate 12 and a nut 13, by pulling the pull plate 12, the connecting plate 81 can be driven to move backward, and the backward movement of the connecting plate 81 can drive the insertion rod 82 to move backward so that the insertion rod 82 is disengaged from the inside of the insertion hole 83. At the same time, the backward movement of the insertion rod 82 can drive the limiting ring 11 to move backward. At this time, the spring 10 contracts, and the user can drive the insertion plate 73 to disengage from the slot 74 by moving the second bridge-type top plate 72. The nut 13 can fix and limit the knob screw 6, thereby improving the stability of the knob screw 6.

[0032] refer to Figure 2The top of the second bridge-shaped top plate 72 is fixedly connected with a fixing plate 14 , the left side of the bottom of the fixing plate 14 is in contact with the top of the first bridge-shaped top plate 71 , and a protective shell 15 is provided on the outer side of the pulling plate 12 .

[0033] As a technical optimization scheme of the utility model, by setting a fixing plate 14 and a protective shell 15, the fixing plate 14 can limit the first bridge-type top plate 71 upwards, and when the first tube body 1 expands and drives the first bridge-type top plate 71 to move upward, it can drive the fixing plate 14 and the second bridge-type top plate 72 to move upward synchronously, thereby ensuring that the first tube body 1 and the second tube body 2 are always aligned, and the protective shell 15 can cover the pull plate 12, thereby preventing the pull plate 12 from being hooked with foreign objects when the first tube body 1 and the second tube body 2 are laid.

[0034] refer to Figure 2 Sliding grooves 16 are provided on both sides of the inner wall of the protective shell 15 , and sliding blocks 17 are fixedly connected to both sides of the pull plate 12 , and the surface of the sliding block 17 is slidably connected to the inner wall of the sliding groove 16 .

[0036] The working principle and use process of the utility model are as follows: during use, when it is necessary to connect the first tube body 1 with the second tube body 2, first slide the protective shell 15 upward to reveal the pull plate 12, and then pull the pull plate 12 to drive the connecting plate 81 to move backward. The backward movement of the connecting plate 81 can drive the insertion rod 82 to move backward so that the insertion rod 82 is disengaged from the interior of the slot 74. At the same time, the backward movement of the insertion rod 82 can drive the limit ring 11 to move backward. At this time, the spring 10 contracts, and then the first tube body 1 is aligned with the second tube body 2. At this time, the insertion plate 73 is inserted into the interior of the slot 74, and then the pull plate 12 is released to allow the spring 10 to recover and push the limit ring 11 and the insertion rod 82 to move forward so that the insertion rod 82 is inserted into the interior of the insertion hole 83. Then, the knob screw 6 is rotated to make the knob screw 6 pass through the first bridge-type bottom plate 4 and the second bridge-type bottom plate 5, and then the nut 13 is threadedly connected to the knob screw 6 to complete the connection between the first tube body 1 and the second tube body 2.

[0037] To sum up: this wire mesh skeleton tube connection structure, by setting a first bridge-type bottom plate 4, a second bridge-type bottom plate 5 and a knob screw 6, the knob screw 6 is used to connect the first bridge-type bottom plate 4 and the second bridge-type bottom plate 5, the first bridge-type bottom plate 4 and the second bridge-type bottom plate 5 are connected to represent the connection between the first tube body 1 and the second tube body 2, which solves the problem that in order to facilitate pressing the locking plate into the interior of the locking groove, the size of the stop block and the stop groove need to be small, so the clamping strength between the stop block and the stop groove is not high, and the tube body will be affected by the external temperature and expand and contract due to heat, so when the tube body expands, it will cause the stop block to slide out of the inside of the stop groove, causing separation between the tube bodies.
