Description

Technical Field

[0001] This utility model belongs to the field of rebar sleeve technology, specifically relating to a deformation-resistant rebar sleeve. Background Technology

[0002] A rebar coupler is a component specifically designed for connecting rebars, also known as a rebar splice. It has internal threads that match the threads on the ends of the rebars, allowing two rebars to be securely connected. Rebar couplers are typically made of precision steel tubing, possessing high precision and strength, ensuring the strength and durability of the rebar connection.

[0003] Chinese Patent Application No. 202221451772.3 discloses a non-deformable rebar sleeve, comprising a rebar sleeve body, an installation hole in the middle of the interior of the rebar sleeve body, an internal thread on the inner wall of the installation hole, an inner layer body installed inside the rebar sleeve body, and a mounting seat reserved between the inner layer body and the installation hole. This non-deformable rebar sleeve, by comprising a rebar sleeve body, an inner layer body, reinforcing ribs, and a mounting seat, forms a double structure between the rebar sleeve body and the inner layer body during use, resulting in higher strength than a single-layer structure. The reinforcing ribs, evenly distributed between the rebar sleeve body and the inner layer body via the mounting seat, ensure that when subjected to external pressure, the force is evenly distributed on the outside of the rebar sleeve body, improving its service life and solving the problem of deformation and reduced service life caused by prolonged torsional use.

[0004] The aforementioned patent, by installing a flange at the connection of the reinforcing bars and connecting the flange and the fixing ring together with connecting bolts, ensures the stability of the connection. However, in use, it cannot guarantee that the connecting bolts of the flange and the fixing ring are on the same line, making the structure impractical. Furthermore, in use, after connecting one end of the reinforcing bar sleeve, when connecting the other end of the reinforcing bar, the reinforcing bar needs to be rotated to complete the connection, which is inconvenient.

[0020] 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.

[0021] Example 1

[0022] Please see Figure 1-4The present invention provides the following technical solution: a deformation-resistant rebar sleeve, comprising a rebar sleeve body 1, a rebar sleeve body 2 installed at one end of the rebar sleeve body 1, a fixing ring 3 fixedly connected to the other end of the rebar sleeve body 1, a rebar 5 provided on one side of the fixing ring 3, a connecting ring 6 installed at one end of the rebar 5, a fixing ring 3 also fixedly connected to the end of the rebar sleeve body 2 away from the rebar sleeve body 1, a rebar 8 provided on one side of the rebar sleeve body 2, a connecting ring 6 also installed at one end of the rebar 8, fixing components 4 provided on both sides of the fixing ring 3, and the rebar sleeve body 1 and the rebar sleeve body 2 connected by a rotating component 7.

[0023] Specifically, the fixing component 4 includes a connecting component 41, a fixing seat 42, a fixing trapezoidal lead screw 43, a drive plate 44, a throttle 45, a damping shaft 46, a fixing plate 47, and a rubber pad 48. The connecting component 41 is symmetrically installed on one side of the fixing ring 3. The fixing seat 42 is fixedly connected above the connecting component 41. The fixing trapezoidal lead screw 43 is installed inside the fixing seat 42. The fixing trapezoidal lead screw 43 and the fixing seat 42 are rotatably connected by a bearing. The throttle 45 is fixedly connected to one end of the fixing trapezoidal lead screw 43. The drive plate 44 is threadedly connected to the surface of the fixing trapezoidal lead screw 43. The drive plate 44 and the fixing seat 42 are slidably connected. The fixing plate 47 is installed at one end of the drive plate 44. The fixing plate 47 and the drive plate 44 are rotatably connected by a damping shaft 46. The rubber pad 48 is fixedly connected to one side of the fixing plate 47.

[0024] By adopting the above technical solution, the first reinforcing bar 5 is connected to the first reinforcing bar sleeve body 1, and the second reinforcing bar 8 is connected to the second reinforcing bar sleeve body 2, so that the fixed ring 3 and the connecting ring 6 are in contact. Then, under the action of the damping shaft 46, the fixing plate 47 is rotated to the inner side, close to the center of the fixing ring 3. Then, the handle 45 is rotated. The rotation of the handle 45 will drive the fixed trapezoidal screw 43 to rotate. The rotation of the fixed trapezoidal screw 43 will drive the fixing plate 47 to move, so that the fixing plate 47, together with the rubber pad 48, will fasten and fix the connecting ring 6 and the fixing ring 3, thereby improving the stability after connection.

[0025] Specifically, the connecting assembly 41 includes a connecting block 411, a connecting screw 412, and a rubber preload pad 413. The connecting block 411 is symmetrically installed on one side of the fixing ring 3. One end of the connecting block 411 is fixedly connected to the fixing seat 42. The connecting screw 412 is installed in the middle of the connecting block 411. The surface of one end of the connecting screw 412 is covered with a rubber preload pad 413.

[0026] By adopting the above technical solution, the connecting screw 412 facilitates the assembly between the connecting block 411 and the fixing ring 3, thereby assembling the fixing ring 3 and the fixing component 4. The rubber pre-tightening pad 413 helps to improve the fixing effect of the connecting screw 412.

[0027] Specifically, the fixed trapezoidal lead screw 43 is fixedly connected to a limit block 49 at one end inside the drive plate 44, and a threaded hole for a mating screw 412 is provided on one side of the fixed ring 3.

[0028] By adopting the above technical solution, the limiting block 49 can prevent the drive plate 44 from disengaging from the fixed trapezoidal lead screw 43.

[0029] In this embodiment, when in use: Rebar 5 is connected to Rebar Sleeve Body 1, and Rebar 8 is connected to Rebar Sleeve Body 2, so that the fixing ring 3 and the connecting ring 6 are in contact. Then, under the action of the damping shaft 46, the fixing plate 47 is rotated to the inside, close to the center of the fixing ring 3. Then, the handle 45 is rotated, which will drive the fixing trapezoidal screw 43 to rotate. The rotation of the fixing trapezoidal screw 43 will drive the fixing plate 47 to move, so that the fixing plate 47, together with the rubber pad 48, will fasten and fix the connecting ring 6 and the fixing ring 3, improving the stability after connection. When using the connecting component 41, the connecting screw 412 facilitates the assembly between the connecting block 411 and the fixing ring 3, thereby assembling the fixing ring 3 and the fixing component 4. The rubber pre-tightening pad 413 facilitates the fixing effect of the connecting screw 412, so that when the device is used, it can easily connect and fix the fixing ring 3 and the connecting ring 6 on the rebar, improving the stability of the connection between the rebar and the rebar sleeve.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that, specifically, the rotating assembly 7 includes a rotating seat 71, a rotating groove 72, a rotating block 73, a connecting column 74, and a fastening screw 75. One end of the rebar sleeve body 1 is fixedly connected to the rotating seat 71. The rotating seat 71 has a rotating groove 72 inside. The rotating block 73 is rotatably connected inside the rotating groove 72. One side of the rotating block 73 is fixedly connected to the connecting column 74. The connecting column 74 and the rotating seat 71 are rotatably connected. The end of the connecting column 74 away from the rotating block 73 is fixedly connected to the rebar sleeve body 2. The upper part of the rotating seat 71 is threadedly connected to the fastening screw 75, which abuts against the rotating block 73.

[0032] By adopting the above technical solution, after the first reinforcing bar 5 and the first reinforcing bar sleeve body 1 are connected, the second reinforcing bar 8 is then moved to the second reinforcing bar sleeve body 2. The rotating block 73 rotates in the rotating groove 72 in the rotating seat 71, thereby enabling the second reinforcing bar sleeve body 2 to rotate and install the second reinforcing bar 8.

[0033] Specifically, a hexagonal rotating block is fixedly connected to the surface of the rebar sleeve body 1, and a hexagonal rotating block is also fixedly connected to the surface of the rebar sleeve body 2.

[0034] By adopting the above technical solution, the hexagonal swivel block makes it easy to rotate the rebar sleeve body 1 and the rebar sleeve body 2.

[0035] In this embodiment, after the first rebar 5 and the first rebar sleeve body 1 are connected, the second rebar 8 is moved to the second rebar sleeve body 2. The rotating block 73 rotates in the rotating groove 72 in the rotating seat 71, thereby allowing the second rebar sleeve body 2 to rotate and install the second rebar 8. The hexagonal rotating block makes it easy to rotate the first rebar sleeve body 1 and the second rebar sleeve body 2. This makes it easy to install the second rebar 8 after the first rebar 5 is installed, without having to rotate the second rebar 8.

[0036] The structure and working principle of the rebar sleeve body 1, rebar sleeve body 2, and fixing ring 3 in this utility model have been disclosed in a non-deformable rebar sleeve disclosed in Chinese Patent Application No. 202221451772.3. The working principle is as follows: both rebar sleeve body 1 and rebar sleeve body 2 include a rebar sleeve main body, a buffer spring, a hollow sleeve base, internal threads, a hinge rod, an inner layer, and reinforcing ribs. The two ends of the rebar are inserted into the mounting holes. The outer wall of the rebar is provided with external threads, allowing it to be directly rotated into the interior of the rebar sleeve main body. A double structure is formed between the rebar sleeve main body and the inner layer, which is more efficient than a single-layer structure. The structure has higher strength, and reinforcing ribs are installed between the main body and inner layer of the rebar sleeve through mounting brackets. The reinforcing ribs are evenly distributed between the main body and inner layer of the rebar sleeve. When subjected to external pressure, the force will be evenly distributed on the outside of the main body of the rebar sleeve, making it less prone to deformation. The mounting brackets are equipped with buffer springs through hollow sleeves. When the main body of the rebar sleeve is hit by an external object, the main body of the rebar sleeve will vibrate under the force. Under the action of the buffer springs, it plays a role in buffering and shock absorption, reducing the impact force brought by external forces. Furthermore, hinge rods are movably hinged at both ends of the hollow sleeve, which have a certain guiding effect and increase the stability of the structure.

[0037] The working principle and usage process of this utility model are as follows: In use, the rebar sleeve body 1 and the rebar sleeve body 2 have anti-deformation effects. Reinforcing ribs are installed between the main body and inner layer of the rebar sleeve body 1 and the rebar sleeve body 2 via mounting brackets. These reinforcing ribs are evenly distributed between the main body and inner layer of the rebar sleeve. When subjected to external pressure, the force is evenly distributed on the outside of the rebar sleeve body, making deformation less likely. A buffer spring is installed between the mounting brackets via a hollow sleeve. When the rebar sleeve body is impacted by an external object, the rebar sleeve body vibrates under the force. The buffer spring acts as a buffer and shock absorber, reducing the impact of external forces. The hollow sleeve has hinged rods at both ends, providing a guiding function and increasing the stability of the structure. In use, the rebar 5 and the rebar sleeve body 1 are threaded together, causing the fixing ring 3 and the connecting ring 6 to fit together. Then, under the action of the rotating component 7, the rebar sleeve body 2 is rotated to install the rebar 8. Afterwards, the fixing component 4 is used to tighten and fix the fixing ring 3 and the connecting ring 6, thereby improving the stability of the connection between the rebar and the rebar sleeve. When using the fixing component 4, the rebar 5 is connected to the rebar sleeve body 1, and the rebar 8 is connected to the rebar sleeve body 2, causing the fixing ring 3 and the connecting ring 6 to fit together. Under the action of the damping shaft 46, the fixed plate 47 is rotated to the inner side, close to the center of the fixed ring 3. Then, the handle 45 is rotated, which drives the fixed trapezoidal screw 43 to rotate. The rotation of the fixed trapezoidal screw 43 drives the fixed plate 47 to move, so that the fixed plate 47, together with the rubber pad 48, secures the connecting ring 6 and the fixed ring 3, improving the stability after connection. When using the connecting assembly 41, the connecting screw 412 facilitates the assembly between the connecting block 411 and the fixed ring 3, thereby assembling the fixed ring 3 and the fixed assembly 4. The rubber pre-tightening pad 413 improves the fixing effect of the connecting screw 412, making the device... In use, the device facilitates the connection and fixation of the fixed ring 3 and the connecting ring 6 on the reinforcing bar, improving the stability of the connection between the reinforcing bar and the reinforcing bar sleeve. When the rotating component 7 is in use, after the reinforcing bar 5 and the reinforcing bar sleeve body 1 are connected, the reinforcing bar 8 is moved to the reinforcing bar sleeve body 2. The rotating block 73 rotates in the rotating groove 72 in the rotating seat 71, thereby allowing the reinforcing bar sleeve body 2 to rotate and install the reinforcing bar 8. The hexagonal rotating block allows for easy rotation of the reinforcing bar sleeve body 1 and the reinforcing bar sleeve body 2, making it easy to install the reinforcing bar 8 after the reinforcing bar 5 is installed, without needing to rotate the reinforcing bar 8.

[0038] 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.
