Description

Technical Field

[0001] This utility model belongs to the field of pipeline installation technology, specifically a pipe opening protection structure. Background Technology

[0002] The main function of pipelines is to transport fluid media, such as gases, liquids, or fluids containing solid particles. They are widely used in industries, municipal works, agriculture, and other fields. Therefore, there are various types of pipelines, and different materials are used depending on the environment in which they are used.

[0003] PVC pipes are mainly composed of polyvinyl chloride, with other components added to enhance their heat resistance, toughness, and ductility. They are most commonly used in municipal drainage operations.

[0004] When connecting PVC pipes, glue is generally used for bonding. Before bonding, the pipe joints need to be cleaned and roughened to ensure the roughness and cleanliness of the pipe openings, which can improve the adhesion of the adhesive. Since the pipes are generally 4-6 meters long and are usually placed on the ground, the work position is in mid-air. Therefore, when the pipes are moved, they will inevitably come into contact with other objects, which will cause the roughened and cleaned pipe openings to be contaminated, affecting the subsequent bonding effect.

[0005] Therefore, it is urgent to design a protective structure to protect the pipe opening, so as to ensure the cleanliness of the pipe opening and the effectiveness of the bonding. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In this utility model:

[0024] Reference Figure 1-4 A pipe opening protection structure includes a sleeve 1, with support rods 101 symmetrically fixed on both sides of the sleeve 1. Each end of the two support rods 101 is fixed with a snap-fit ​​block 2. The snap-fit ​​block 2 is provided with a protective component to prevent pipe opening wear and contamination. The sleeve 1 is provided with a support component for connecting the pipe opening.

[0025] The protective components include: a slide 201, a slot 202, a protective cylinder 4, an airbag 401, a locking block 402, and an extension nozzle 403;

[0026] The snap-fit ​​block 2 has a groove 201 on its surface and a slot 202 on the side of its surface near the groove 201, with the groove 201 and slot 202 communicating with each other. A protective cylinder 4 is provided outside the snap-fit ​​block 2. An airbag 401 is fitted along the inner edge of the protective cylinder 4, and an extension nozzle 403 of the airbag 401 extends outward from the protective cylinder 4. symmetrical snap-fit ​​blocks 402 are fixedly installed on both sides inside the protective cylinder 4, and the snap-fit ​​blocks 402 fit into the groove 201 and slot 202. There are two sets of slots 202. The slots 202 on the two sets of locking blocks 2 are arranged symmetrically at the center. The protective cylinder 4 is put on the outside of the locking block 2, so that the locking blocks 402 on both sides inside the protective cylinder 4 are aligned with the slide groove 201 and slide into the slide groove 201. Then the protective cylinder 4 is rotated so that the locking blocks 402 are locked into the slots 202, thereby connecting the protective cylinder 4 to the outside of the locking block 2, thus protecting the pipe opening inside the protective cylinder 4, avoiding friction between the pipe opening and the outside environment, which would cause wear and contamination and be detrimental to subsequent connection work.

[0027] The support assembly includes: movable rod 3, connecting rod A301, support block 302, rubber pad 3021, and connecting rod B303;

[0028] A movable rod 3 is slidably connected through the inside of the sleeve 1. Connecting rods A301 are movably connected to both ends of the movable rod 3 via pivots. Connecting rods B303 are movably connected to both sides of the sleeve 1 via pivots. Support blocks 302 are movably connected to the ends of connecting rods A301 and B303 via pivots. Rubber pads 3021 are fitted onto the surface of support blocks 302. There are at least two support components. Connecting rods A301 and B303 are of the same length and are symmetrically arranged. When the pipe opening is fitted over the support block 302, the movable rod 3 is pulled inward, causing it to move inward. The connecting rods A301 on both sides of the movable rod 3 extend outward under the action of the pivots. Under the drive of connecting rods A301, connecting rods B303 also extend outward at the same time, thereby increasing the distance between support blocks 302 and movable rods 3. This allows support blocks 302 to support the inner wall of the pipe opening.

[0029] Furthermore, threaded holes are provided on one side of both the sleeve 1 and the movable rod 3. Bolts are simultaneously screwed into the threaded holes of the sleeve 1 and the movable rod 3 to fix the movable rod 3.

[0030] Furthermore, the rubber pad 3021 is arc-shaped and has anti-slip texture on its surface. The arc-shaped rubber pad 3021 can better fit the shape inside the pipe opening, and the anti-slip texture on the surface has a certain anti-slip effect, making it less likely for the pipe opening to fall off during the support process.

[0031] Furthermore, the airbag 401 is made of nitrile banana oil, which has better wear resistance and oil resistance.

[0032] Working principle: First, the pipe opening is fitted onto the outside of the support block 302. By pulling the movable rod 3, it moves inward. The connecting rods A301 on both sides of the movable rod 3 extend outward under the action of the rotating shaft. Driven by the connecting rods A301, the connecting rod B303 also extends outward, increasing the distance between the support block 302 and the movable rod 3. This allows the support block 302 to rest against the inner wall of the pipe opening, thus supporting it. The arc-shaped rubber pad 3021 conforms better to the internal shape of the pipe opening, and its anti-slip texture provides a certain degree of slip resistance, preventing the pipe opening from easily falling off during support. Then, bolts are simultaneously screwed into the threaded holes of the sleeve 1 and the movable rod 3, thereby securing the movable rod... 3. Fixing: Finally, put the protective cylinder 4 on the outside of the snap-fit ​​block 2, align the snap-fit ​​blocks 402 on both sides of the inside of the protective cylinder 4 with the slide groove 201 and slide them into the slide groove 201. Then rotate the protective cylinder 4 so that the snap-fit ​​blocks 402 are snapped into the snap-fit ​​groove 202, thereby connecting the protective cylinder 4 to the outside of the snap-fit ​​block 2, thus protecting the pipe opening inside the protective cylinder 4, avoiding wear and contamination caused by friction between the pipe opening and the outside, which is not conducive to subsequent connection work. At the same time, if necessary, the air bag 401 can be inflated by extending the air nozzle 403 to contact the valve, further achieving the purpose of preventing detachment. It can also block the opening of the protective cylinder 4 to prevent dust from entering, which can further achieve the purpose of protecting the pipe opening.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
