Description

Technical Field

[0001] The utility model belongs to the technical field of polyester sleeves, and particularly relates to a polyester sleeve with a convenient wrapping structure. Background Technique

[0002] A polyester sleeve is a material used for pipeline protection and anti-corrosion. It is usually made of polyester resin and has excellent corrosion resistance, strength and toughness. Compared with the polyester sleeve used for wrapping cables, the polyester sleeve used for wrapping pipelines is harder and has a certain shape retention. When wrapping the pipeline, the polyester sleeve is generally cut into several sections, and then these sections of polyester sleeves are sleeved on the outside of the pipeline one by one. Then, sealant and adhesive are used to connect and fix the segmented polyester sleeves. Finally, the pipeline is heated to make the polyester sleeve closely connected to the outside of the pipeline. Although this method can indeed wrap the polyester sleeve on the outside of the pipeline, its disadvantage is that although the joints of the segmented polyester sleeves are sealed with adhesive and sealant during each section, its durability will be greatly reduced compared with the whole-section wrapping. Secondly, a lot of time will be spent on the sealing operation, thus reducing the work efficiency. Therefore, a new structure is proposed to solve the above problems. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a polyester sleeve with a convenient wrapping structure to solve the problems put forward in the above background technique.

[0004] The utility model is realized through the following technical solutions: A polyester sleeve with a convenient wrapping structure, comprising: a sleeve clamping mechanism, a sleeve tightening mechanism and a support sleeve. The sleeve tightening mechanism is installed at the rear of the sleeve clamping mechanism, and the support sleeve is provided at the rear of the sleeve tightening mechanism;

[0005] The sleeve clamping mechanism includes: a traction socket and a clamping thread piece. The rear side of the traction socket is welded and fixed to the front side of the clamping thread piece. The front of the traction socket is provided with a sleeve opening in a penetrating manner. Four groups of the clamping thread pieces are arranged at equal intervals in a ring shape, and a first rubber layer is glued to the inner side of the clamping thread piece;

[0006] The front of the sleeve tightening mechanism is provided with a screw interface in a penetrating manner. A number of anti-slip grooves are opened on the outside of the sleeve tightening mechanism. The rear side of the sleeve tightening mechanism is welded and fixed to the front side of the support sleeve, and a second rubber layer is glued to the inner side of the support sleeve.

[0007] As a preferred embodiment, four groups of traction rings are equidistantly arranged on the outer side of the traction socket. The radius length of the sleeve opening matches the radius length of the pipeline to be covered. Nylon ropes are tied to the outer sides of the traction rings. The nylon ropes are connected to an external traction mechanism, and the traction mechanism can be used as a traction power to pull the sleeve clamping mechanism, the sleeve tightening mechanism, and the support sleeve forward to perform the covering work.

[0008] As a preferred embodiment, a clamping groove is formed by being recessed forward between the four groups of clamping threaded sheets and the sleeve opening. The width of the clamping groove matches the wall thickness of the polyester sleeve.

[0009] As a preferred embodiment, the clamping threaded sheet is of an arc-shaped structure. The radius length of the circle formed by the four groups of clamping threaded sheets matches the radius length of the polyester sleeve. Threads are provided on the outer side of the clamping threaded sheet, and the threads on the outer sides of the four groups of clamping threaded sheets form a complete thread group.

[0010] As a preferred embodiment, the radius length of the circular area formed by the four groups of clamping threaded sheets matches the radius length of the screw connection port. An internal thread groove matching the specification of the thread group is provided inside the screw connection port.

[0011] As a preferred embodiment, the screw connection port is of a horn-shaped structure with a gradually shrinking diameter from front to back. The length of the screw connection port extending backward matches the length of the clamping threaded sheet. During the process of the clamping threaded sheet being screwed backward, since the part of the screw connection port extending backward is of a horn-shaped structure with a gradually shrinking diameter backward, the four groups of clamping threaded sheets gradually contract inward as the screw connection deepens, and then the four groups of rubber layers I are pressed against the outer side of the polyester sleeve, so that the polyester sleeve can be clamped tightly, facilitating the subsequent covering work.

[0012] As a preferred embodiment, the radius length of the support sleeve matches the radius length of the polyester sleeve. The support sleeve is used to support the rear part of the polyester sleeve to keep it horizontal for the insertion of the pipeline. At the same time, the rubber layer II can protect the outer side of the polyester sleeve from being scratched by the support sleeve.

[0013] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By setting the clamping threaded piece and the screwing groove, the sleeve tightening mechanism and the support sleeve are first sleeved on the outside of the polyester sleeve, and then the front side of the polyester sleeve is placed inside the clamping groove. Move the sleeve tightening mechanism forward so that the four clamping threaded pieces are screwed to the rear with the screwing interface. Since the structure is trumpet-shaped after screwing, as the screwing connection deepens, the caliber of the rear sides of the four clamping threaded pieces gradually tightens, and the outer side of the polyester sleeve is tightened by the four rubber layers, thereby firmly clamping the front end of the polyester sleeve inside the clamping groove. At this time, the rear side of the polyester sleeve is supported by the support sleeve, so it is more convenient for the next wrapping work. Insert the pipeline to be wrapped backward through the sleeve opening, so that the pipeline passes through the sleeve opening and is inserted backward into the polyester sleeve until the whole pipeline is completely inserted into the polyester sleeve. The final effect is that the wrapping efficiency of the polyester sleeve is greatly improved, and at the same time, since the polyester sleeve is integrally sleeved, the durability of the polyester sleeve is greatly improved compared with segmented sleeving.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 6 : A polyester casing with a convenient coating structure, including: a casing clamping mechanism 100, a casing tightening mechanism 200, and a support sleeve 300. The casing tightening mechanism 200 is installed at the rear of the casing clamping mechanism 100, and the support sleeve 300 is provided at the rear of the casing tightening mechanism 200;

[0026] The casing clamping mechanism 100 includes: a traction socket 110 and a clamping threaded piece 120. The rear side of the traction socket 110 is welded and fixed to the front side of the clamping threaded piece 120. The front of the traction socket 110 is provided with a casing opening 101 in a penetrating manner. Four groups of clamping threaded pieces 120 are arranged at equal intervals in a ring shape, and a first rubber layer 121 is adhesively bonded to the inner side of the clamping threaded piece 120;

[0027] The front of the casing tightening mechanism 200 is provided with a screw joint 201 in a penetrating manner. A number of anti-slip grooves are formed on the outer side of the casing tightening mechanism 200. The rear side of the casing tightening mechanism 200 is welded and fixed to the front side of the support sleeve 300. A second rubber layer 310 is adhesively bonded to the inner side of the support sleeve 300.

[0028] Four groups of traction rings 111 are arranged at equal intervals on the outer side of the traction socket 110. The radius length of the casing opening 101 matches the radius length of the pipeline to be coated. Nylon ropes are tied to the outer sides of the traction rings 111, and the nylon ropes are connected to an external traction mechanism. The casing clamping mechanism 100, the casing tightening mechanism 200, and the support sleeve 300 can be pulled forward by the traction mechanism as the traction power to perform the coating work.

[0029] A clamping groove 122 is formed by the four groups of clamping threaded pieces 120 and the casing opening 101 recessing forward. The width of the clamping groove 122 matches the wall thickness of the polyester casing.

[0030] The clamping threaded piece 120 is of an arc-shaped structure. The radius length of the circle formed by the four groups of clamping threaded pieces 120 matches the radius length of the polyester sleeve. Threads are provided on the outer side of the clamping threaded piece 120, and the threads on the outer sides of the four groups of clamping threaded pieces 120 form a complete thread group.

[0031] The radius length of the circular area formed by the four groups of clamping threaded pieces 120 matches the radius length of the screw joint 201. An internal thread groove matching the specification of the thread group is provided on the inner side of the screw joint 201.

[0032] The screw joint 201 is of a horn-shaped structure with a gradually shrinking diameter from front to back. The length of the screw joint 201 extending backward matches the length of the clamping threaded piece 120. During the process of the clamping threaded piece 120 being screwed backward, since the part of the screw joint 201 extending backward is a horn-shaped structure with a gradually decreasing diameter backward, the four groups of clamping threaded pieces 120 gradually contract inward as the screw connection deepens, and then the four groups of rubber layers 121 are pressed against the outer side of the polyester sleeve, so that the polyester sleeve can be clamped tightly, facilitating the subsequent coating work.

[0033] The radius length of the support sleeve 300 matches the radius length of the polyester sleeve. The support sleeve 300 is used to support the rear part of the polyester sleeve to keep it horizontal for the insertion of the pipeline. At the same time, the rubber layer 310 can protect the outer side of the polyester sleeve from being scratched by the support sleeve 300.

[0034] Example 1: Please refer to Figures 1 to 6, during actual use, first pick up the sleeve tightening mechanism 200 and the support sleeve 300. Pass the front side of the polyester sleeve through the inside of the support sleeve 300 and the sleeve tightening mechanism 200 respectively, and let the front end of the polyester sleeve pass out from the screw connection port 201. Then hold the outside of the support sleeve 300 with the left hand, pick up the sleeve clamping mechanism 100 with the right hand, insert the front end of the polyester sleeve into the clamping groove 122 at the rear of the sleeve clamping mechanism 100. Then slowly move the sleeve clamping mechanism 100 backward, so that the four groups of clamping threaded pieces 120 at the rear of the sleeve clamping mechanism 100 are inserted backward into the screw connection port 201 opened on the front of the sleeve tightening mechanism 200. Rotate the sleeve clamping mechanism 100 clockwise, so that the four groups of clamping threaded pieces 120 are threadedly connected with the screw connection port 201 and slowly pushed backward. Since the diameter of the part where the screw connection port 201 extends backward gradually decreases, during the process of the clamping threaded pieces 120 being pushed backward, the four groups of clamping threaded pieces 120 gradually contract inward, so that the rubber layer 121 glued to the inner side of the four groups of clamping threaded pieces 120 gradually presses the outer side of the front end of the polyester sleeve, and finally firmly clamps the part of the polyester sleeve in the clamping groove 122. At this time, the rear side of the polyester sleeve is inside the support sleeve 300, and the support sleeve 300 plays a supporting role for the polyester sleeve. At the same time, the rubber layer 310 inside the support sleeve 300 can protect the outer side of the polyester sleeve from being scratched, keep the rear part of the polyester sleeve horizontal, and facilitate the insertion of the pipeline in the later stage. The final effect is that through the clamping and support of the polyester sleeve, it is convenient to carry out the wrapping work on the pipeline, and the wrapping efficiency is greatly improved.

[0035] Embodiment 2: Please refer to Figure 1 , after the polyester sleeve is clamped, pick up the pipeline to be wrapped at this time. It should be noted that the pipeline needs to be cleaned and coated with primer in advance before wrapping. The primer will not hinder the insertion work of the pipeline before it is dried. Then insert the sleeve port 101 on the front of the sleeve clamping mechanism 100 forward to the outside of the pipeline, so that the rear side of the pipeline is inserted backward into the sleeve clamping mechanism 100 for a part. Then tie a nylon rope to the outside of the traction ring 111, and drive the sleeve clamping mechanism 100, the sleeve tightening mechanism 200 and the support sleeve 300 to move forward by pulling the nylon rope through an external traction mechanism. Therefore, the polyester sleeve can be wrapped on the outside of the pipeline at one time. The polyester sleeve has a certain elasticity, so after the socketing is completed, the polyester sleeve is wrapped on the outside of the pipeline under the action of elasticity. After the wrapping is completed, rotate the sleeve clamping mechanism 100 in the reverse direction and remove it, and then remove the sleeve tightening mechanism 200 and the support sleeve 300 from the front side of the polyester sleeve to complete the final wrapping work. The final effect is that the wrapping efficiency is greatly improved, and the overall socketing method greatly improves the durability of the polyester sleeve.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
