Abstract
Description
Technical Field
[0001] The utility model relates to a sheath, in particular to a detachable wall-piercing and floor-piercing sheath. Background Art
[0002] Pipeline transportation refers to the process of transporting substances such as liquids, gases, and solid particles from one location to another through pipelines. Pipeline transportation has extensive applications in industrial production, energy transportation, water supply, etc. It is usually more economical and efficient than other transportation methods (such as railway and road transportation), especially suitable for large-scale long-distance transportation. During the pipeline transportation process, in order to reduce the heat loss of the pipeline transportation medium, improve energy utilization efficiency, and also prevent the pipeline from dew condensation or freezing and cracking in a low-temperature environment, a sheath is now used to wrap the outside of the pipeline in some specific environments. However, during the long-distance transportation of the pipeline, it often needs to pass through wall panels or floor slabs. Currently, installation holes are usually opened in the wall panels or floor slabs. After the installation holes are opened, it is not convenient to adjust the size, which easily leads to air leakage. Content of the Utility Model
[0003] The purpose of the utility model is to provide a detachable wall-piercing and floor-piercing sheath. It can be applicable to pipelines of different sizes and has good sealing performance.
[0004] The technical solution of the utility model: A detachable wall-piercing and floor-piercing sheath includes a support cylinder arranged in a pipeline hole of a wall. Outer covers are arranged at both ends of the support cylinder and are respectively located on both sides of the wall. An outer cover fixing edge for realizing the sealing between the wall and the outer cover is arranged at the connection end of the outer cover and the wall. A rotating collar is arranged inside the support cylinder. Multiple groups of limiting grooves with continuously decreasing radii are arranged on the rotating collar. An installation sleeve for fixing the pipeline is arranged on one side of the rotating collar and is fixed inside the support cylinder. Multiple groups of radially arranged elastic locking buckles are arranged outside the installation sleeve. A resisting block for fixing the pipeline is arranged at the end of the elastic locking buckle.
[0005] In the aforementioned detachable wall-piercing and floor-piercing sheath, multiple groups of uniformly distributed limiting columns are arranged on the outer side of the rotating collar, and the axis center of the rotating collar is located outside the pipeline hole of the wall. The limiting columns penetrate through the support cylinder, and a locking member for locking the rotating collar and the support cylinder is arranged on the limiting columns.
[0006] In the aforementioned detachable wall-piercing and floor-piercing sheath, the elastic locking buckle includes a support seat arranged inside the installation sleeve. A radially arranged resisting rod is arranged in the support seat. A resisting seat is arranged on the resisting rod. A support spring is arranged between the resisting seat and the support seat. One end of the resisting rod is connected to the resisting block, and a guide block corresponding to the limiting groove is arranged at the other end of the resisting rod.
[0007] In the aforementioned detachable wall-piercing and floor-piercing sheath, a sealing pad for abutting against the wall is arranged on the outer cover fixing edge.
[0008] In the aforementioned detachable wall-piercing and floor-piercing sheath, a guide groove corresponding to the limit post is provided on the support cylinder.
[0009] Compared with the prior art, the utility model provides support by arranging a support cylinder in the wall, and outer covers are arranged at both ends of the support cylinder to prevent air leakage. Due to the differences in pipe sizes, the application can rotate the collar, so as to press the abutting block at the end of the elastic lock to fix the pipe, with better applicability.

Detailed Embodiment
[0013] The following further illustrates the utility model with reference to the drawings and embodiments, but it shall not be used as a basis for limiting the utility model.
[0014] Embodiment. A detachable wall-piercing and floor-piercing sheath is composed as Figure 1-2 shown, including a support cylinder 1 arranged in the pipe hole of the wall. Outer covers 2 are arranged at both ends of the support cylinder 1 and are respectively located on both sides of the wall. An outer cover fixing edge 3 for sealing the wall and the outer cover 2 is provided at the connection end of the outer cover 2 and the wall. A rotating collar 4 is arranged inside the support cylinder 1. Multiple groups of limit grooves 5 with continuously decreasing radii are provided on the rotating collar 4. An installation sleeve 6 for fixing the pipe is arranged on one side of the rotating collar 4 and is fixed inside the support cylinder 1. Multiple groups of radially arranged elastic locks 7 are provided outside the installation sleeve 6, and an abutting block 8 for fixing the pipe is provided at the end of the elastic lock 7.
[0015] Multiple groups of uniformly distributed limit posts 9 are arranged on the outer side of the rotating collar 4, and the axis center of the rotating collar 4 is located outside the pipe hole of the wall. The limit posts 9 penetrate through the support cylinder 1, and a locking member for locking the rotating collar 4 and the support cylinder 1 is provided on the limit posts 9.
[0016] The elastic lock 7 includes a support seat 10 arranged inside the installation sleeve 6. A radially arranged abutting rod 11 is arranged in the support seat 10. An abutting seat 12 is arranged on the abutting rod 11. A support spring 13 is arranged between the abutting seat 12 and the support seat 10. One end of the abutting rod 11 is connected to the abutting block 8, and a guide block 14 corresponding to the limit groove 5 is arranged at the other end of the abutting rod 11.
[0017] A sealing gasket 15 that abuts against the wall body is provided on the outer cover fixing edge 3 described above.
[0018] A guide groove 16 corresponding to the limit post 9 is provided on the support cylinder 1 described above.
[0019] Principle of the utility model: When this application is used, first, a pipeline hole is opened in a wall body or a layer body, and then the support cylinder 1 is installed in the pipeline hole. The gap between the pipeline hole and the support cylinder 1 can be filled with a sealing and heat-insulating material to avoid air leakage. Then, the rotating collar 4 is rotated through the limit post, so that the rotating collar 4 moves in a direction away from pressing the elastic lock catch 7, and thus the abutting rod 11 moves in a direction away from the axis under the action of the support spring 13. At this time, the pipeline can be installed, and the pipeline is placed between multiple groups of abutting blocks 8. Then, the rotating collar 4 is rotated. During the rotation of the rotating collar 4, due to the cooperation of the limit groove 5 and the guide block 14, the abutting rod 11 will be pressed to move in the axial direction to lock the pipeline. Finally, the rotating collar 4 is fixed on the support cylinder 1 through the cooperation of the fastener and the limit post 9, so that the rotating collar 4 cannot rotate relative to the support cylinder 1, and the stable fixation of the pipeline is realized. The end of the limit post 9 is provided with an external thread, and the fastener can be a nut, a gasket, etc. Finally, the outer cover 2 is fixed at both ends of the support cylinder 1. The outer cover 2 can be connected to the support cylinder 1 by means of screws, etc. This is the prior art, so it is not described in detail. When installing pipelines with different diameters, by changing the positions of the rotating collar 4 and the support cylinder 1, different positions of the limit groove 5 are abutted against the guide block 14, so that the abutting blocks 8 at the end of the abutting rod 11 can more stably fix the pipeline, and thus the applicability is better. The outer cover is selected to correspond to the pipe diameter, so that the connection between the outer cover and the pipeline is sealed, and the sealing performance is better. And in this way, it is necessary to remove the entire sheath, and the pipeline replacement is more convenient.
