Abstract

This utility model relates to the field of protective cover technology, specifically a protective cover for connecting a rebar threaded sleeve. It includes a protective cover body, with a sealing plug and a sealing sleeve fixedly connected to the left side wall of the protective cover body. The sealing plug is located in the middle of the left side wall of the protective cover body, and the sealing sleeve is located outside the sealing plug. The protective cover body is inserted into one end of the rebar threaded sleeve via the sealing plug. In operation, the sealing plug is fully inserted into the exposed end of the rebar threaded sleeve. The threaded sleeve is rotated counterclockwise to move to the left along the outer wall of the threaded tube. The threaded sleeve drives the connecting rod and the compression ring to move to the left. The compression ring compresses the circular rubber strip and the sealing sleeve, causing the sealing sleeve to deform and tightly adhere to the outer wall of the rebar threaded sleeve. This reduces the gap between the inner wall of the sealing sleeve and the outer wall of the rebar threaded sleeve, forming an outer seal and reducing the entry of external dust and moisture into the rebar threaded sleeve.

Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, specifically a protective cover for a steel bar straight thread sleeve connection. Background Technology

[0002] In building construction, rebar connection is a crucial step, directly affecting the safety and stability of the building structure. Straight threaded sleeve connections for rebars, as an efficient and reliable connection method, are widely used in building engineering.

[0003] During construction, there are often reserved openings for subsequent construction. Rebar threaded sleeves are generally used as connection devices, i.e., connectors, for the rebars. The connection points of these sleeves are easily corroded by dust, impurities, and moisture, leading to rust and corrosion, affecting connection strength and service life, and potentially causing safety accidents. Therefore, how to effectively protect the rebar threaded sleeves and ensure their connection strength and reliability is one of the problems that needs to be solved in the current use of rebar threaded sleeves. To address this, a rebar threaded sleeve connection protection cover is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a protective cover for a straight threaded sleeve connection of reinforcing bars, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective cover for a rebar straight thread sleeve connection, comprising a protective cover body, a sealing plug and a sealing sleeve fixedly connected to the left side wall of the protective cover body, the sealing plug being located in the middle of the left side wall of the protective cover body, and the sealing sleeve being located outside the sealing plug, the protective cover body being inserted into one end of the rebar straight thread sleeve through the sealing plug, the sealing plug being interference-fitted with the inner wall of the rebar straight thread sleeve, a circular rubber strip being fixedly connected to the left side of the outer side wall of the sealing sleeve, a threaded tube being fixedly connected to the outer side wall of the protective cover body, a threaded sleeve being threadedly connected to the outer side wall of the threaded tube, a connecting rod being uniformly fixedly connected to the left side wall of the threaded sleeve, and a compression ring being fixedly connected to the left end of the connecting rod, the inner side wall of the compression ring being a smooth inclined surface.

[0006] As a further preferred embodiment of this technical solution: the outer wall of the threaded sleeve is uniformly and fixedly connected with a handle.

[0007] As a further preferred embodiment of this technical solution: the outer wall of the handle is fitted with a sponge sleeve.

[0008] As a further preferred embodiment of this technical solution: the right side wall of the protective cover body is provided with an internal hexagonal hole.

[0009] As a further preferred embodiment of this technical solution: two fixing blocks are symmetrically fixedly connected to the right side wall of the protective cover body, and a pull ring is hinged between the opposite sides of the two fixing blocks.

[0010] As a further preferred embodiment of this technical solution, the sealing sleeve is made of fluororubber.

[0011] As a further preferred embodiment of this technical solution, the sealing material is natural rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In operation, the sealing plug is fully inserted into the exposed end of the rebar threaded sleeve. The threaded sleeve is rotated counterclockwise, causing it to move to the left along the outer wall of the threaded tube. This movement drives the connecting rod and the compression ring to the left. The compression ring compresses the circular rubber strip and the sealing sleeve, causing the sealing sleeve to deform and tightly adhere to the outer wall of the rebar threaded sleeve. This reduces the gap between the inner wall of the sealing sleeve and the outer wall of the rebar threaded sleeve, forming an outer seal. This reduces the entry of external dust and moisture into the rebar threaded sleeve. Furthermore, the compression force of the compression ring acts as a clamping and fixing mechanism, preventing the sealing sleeve and protective cap from easily detaching from the rebar threaded sleeve's port. The sealing plug, with its interference fit, fills the inner wall of the rebar threaded sleeve's port, forming an inner seal. This further reduces external erosion, preventing rust and corrosion at the rebar threaded sleeve connection, ensuring its connection strength and reliability, and bringing convenience to the use of the rebar threaded sleeve.

[0023] Please see Figure 1-5This utility model provides a technical solution: a protective cover for a rebar straight threaded sleeve connection, including a protective cover body 1. A sealing plug 2 and a sealing sleeve 3 are fixedly connected to the left side wall of the protective cover body 1. The sealing plug 2 is located in the middle of the left side wall of the protective cover body 1, and the sealing sleeve 3 is located outside the sealing plug 2. The protective cover body 1 is inserted into one end of the rebar straight threaded sleeve through the sealing plug 2. The sealing plug 2 is interference-fitted with the inner wall of the rebar straight threaded sleeve. A circular rubber strip 4 is fixedly connected to the left side of the outer wall of the sealing sleeve 3. A threaded tube 5 is fixedly connected to the outer wall of the protective cover body 1. A threaded sleeve 6 is threadedly connected to the outer wall of the threaded tube 5. A connecting rod 7 is evenly fixedly connected to the left side wall of the threaded sleeve 6. A compression ring 8 is fixedly connected to the left end of the connecting rod 7. The inner wall of the compression ring 8 is a smooth bevel. The sealing plug 2 is fully inserted into the exposed end of the rebar straight threaded sleeve, and the screw is rotated counterclockwise. The threaded sleeve 6 moves to the left along the outer wall of the threaded tube 5. The threaded sleeve 6 drives the connecting rod 7 and the compression ring 8 to move to the left. The compression ring 8 compresses the circular rubber strip 4 and the sealing sleeve 3, causing the sealing sleeve 3 to deform and tightly adhere to the outer wall of the straight threaded sleeve of the steel bar. This reduces the gap between the inner wall of the sealing sleeve 3 and the outer wall of the straight threaded sleeve of the steel bar, forming an outer seal. This reduces the entry of external dust and moisture into the straight threaded sleeve of the steel bar. The compression force of the compression ring 8 can also play a role in pressing and fixing, preventing the sealing sleeve 3 and the protective cover body 1 from easily falling off the port of the straight threaded sleeve of the steel bar. The sealing plug 2 is interference-fitted with the straight threaded sleeve of the steel bar, filling the inner wall of the port of the straight threaded sleeve of the steel bar, forming an inner seal. This further reduces external corrosion and prevents rust and corrosion at the connection part of the straight threaded sleeve of the steel bar, ensuring its connection strength and reliability, and bringing convenience to the use of the straight threaded sleeve of the steel bar.

[0024] In this embodiment, specifically: a handle 9 is uniformly and fixedly connected to the outer wall of the threaded sleeve 6; this facilitates the rotation of the threaded sleeve 6 using the handle 9.

[0025] In this embodiment, specifically: a sponge sleeve 10 is provided on the outer wall of the handle 9; to increase the comfort when holding the handle 9.

[0026] In this embodiment, specifically: an internal hexagonal hole 11 is provided on the right side wall of the protective cover body 1; when rotating the threaded sleeve 6, an external wrench is inserted into the internal hexagonal hole 11 to fix the protective cover body 1, preventing the protective cover body 1 from rotating with the threaded sleeve 6.

[0027] In this embodiment, specifically: two fixing blocks 12 are symmetrically fixedly connected to the right side wall of the protective cover body 1, and a pull ring 13 is hinged between the opposite sides of the two fixing blocks 12; so as to facilitate the removal of the protective cover body 1 by means of the pull ring 13.

[0028] In this embodiment, specifically: the sealing sleeve 3 is made of fluororubber; by utilizing the high temperature resistance and chemical corrosion resistance of fluororubber, the environmental applicability of the protective cover is improved.

[0029] In this embodiment, specifically: the sealing plug 2 is made of natural rubber; the high elasticity and wear resistance of natural rubber can ensure the sealing effect of the protective cover and improve its durability.

[0030] The working principle of this utility model is as follows: The sealing plug 2 is fully inserted into the exposed end of the straight threaded sleeve of the reinforcing bar. The threaded sleeve 6 is rotated counterclockwise to move to the left along the outer wall of the threaded tube 5. The threaded sleeve 6 drives the connecting rod 7 and the compression ring 8 to move to the left. The compression ring 8 compresses the circular rubber strip 4 and the sealing sleeve 3, causing the sealing sleeve 3 to deform and tightly adhere to the outer wall of the straight threaded sleeve of the reinforcing bar. This reduces the gap between the inner wall of the sealing sleeve 3 and the outer wall of the straight threaded sleeve of the reinforcing bar, forming an outer seal. This reduces the entry of external dust and moisture into the straight threaded sleeve of the reinforcing bar. Furthermore, the compressive force of the compression ring 8 can also act as a pressure... The sealing sleeve 3 and the protective cover body 1 are fastened to prevent them from easily falling off the port of the rebar threaded sleeve. The sealing plug 2 is interference-fitted with the rebar threaded sleeve, filling the inner wall of the port of the rebar threaded sleeve to form an inner seal, further reducing external erosion and preventing rust and corrosion at the connection part of the rebar threaded sleeve, ensuring its connection strength and reliability, and bringing convenience to the use of the rebar threaded sleeve. When rotating the threaded sleeve 6, the protective cover body 1 is fixed by inserting an external wrench into the internal hexagonal hole 11 to prevent the protective cover body 1 from rotating with the threaded sleeve 6.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
