Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically an adjustable rebar connector. Background Technology

[0002] A rebar connector is a specialized mechanical device used for connecting rebars. It is mainly used for the butt joint, extension, or reinforcement of rebars in building structures. It firmly connects two rebars through mechanical interlocking or squeezing, replacing traditional binding or welding processes and improving construction efficiency and quality.

[0003] Currently, most existing rebar splicing devices rely solely on the threaded connection between the sleeve and the rebar, lacking an additional effective limiting mechanism. During construction, the sleeve is prone to slippage due to external factors such as the impact of concrete pouring and structural vibration, leading to loosening of the rebar connection. Unlike the new adjustable rebar splice, it cannot ensure the stability of the connection, posing a potential threat to the safety of the building structure. Therefore, we propose an adjustable rebar splice. Utility Model Content

[0004] The main objective of this invention is to provide an adjustable rebar connector that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model proposes an adjustable rebar connector, comprising a first rebar and a second rebar. The first rebar has a long external thread at one end, and the second rebar has a short external thread at one end. The first rebar and the second rebar are connected by a connector, which includes:

[0006] A sleeve, wherein the sleeve is provided with an internal thread, the internal thread is engaged with a long external thread and a short external thread, and the outer wall of the sleeve is provided with a sliding groove;

[0007] A limiting sleeve, wherein the limiting sleeve is penetrated by and fixedly connected to the second reinforcing bar, and the limiting sleeve is provided with a limiting groove;

[0008] A limiting rod, which passes through and is slidably connected to the first and second fixing sleeves.

[0009] Preferably, the first and second fixing sleeves are penetrated by the sleeve and fixedly connected to the sleeve.

[0010] Preferably, the sleeve passes through the rotating sleeve and is rotatably connected to the rotating sleeve, the outer wall of the rotating sleeve is provided with an inclined groove, and a positioning block is fixedly connected to the lower outer wall of the rotating sleeve.

[0011] Preferably, the inclined groove is slidably connected to a slider, and the slider is fixedly connected to the end of the limiting rod.

[0012] Preferably, a sliding sleeve is provided below the rotating sleeve, and a protrusion is fixed on the inner wall of the sliding sleeve, and the protrusion is slidably connected to the sliding groove.

[0013] Preferably, the sliding sleeve has a positioning groove one and a positioning groove two, and the included angle between the positioning groove one and the positioning groove two is thirty degrees.

[0014] Preferably, a fixed sleeve three is provided below the sliding sleeve, the fixed sleeve three is fixedly connected to the outer wall of the sleeve, and a spring is provided between the sliding sleeve and the fixed sleeve three.

[0015] This utility model provides an adjustable rebar connector. It has the following advantages:

[0016] (1) The adjustable rebar connector, through the cooperation of the limiting sleeve, the limiting rod and the spring, when the sleeve moves to a certain position during the process of connecting rebar 1 and rebar 2, the limiting rod can spring into the limiting groove of the limiting sleeve under the action of the spring force, effectively restricting the sliding of the sleeve, greatly improving the stability of the connection between rebar 1 and rebar 2, reducing the risk of the sleeve loosening due to external influences, and ensuring the stability of the rebar connection part in the building structure.

[0017] (2) When it is necessary to separate rebar 1 and rebar 2, the adjustable rebar connector is operated by pulling the sliding sleeve to release the limiting position of the rotating sleeve, then turning the rotating sleeve, and using the inclined groove to squeeze the slider to disengage the limiting rod from the limiting groove. Finally, the sliding sleeve is released to allow the positioning block to engage in the second positioning groove for limiting again. After that, turning the sleeve will separate rebar 1 and rebar 2. The entire disassembly and assembly process is simple and convenient, requiring no complicated tools or cumbersome steps, thus improving construction efficiency. Attached Figure Description

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] 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.

[0028] Please see Figures 1-5 This utility model proposes an adjustable rebar connector, including rebar 1 and rebar 2. Rebar 1 has a long external thread 11 at its end, and rebar 2 has a short external thread 21 at its end. Rebar 1 and rebar 2 are connected by the connector.

[0029] In an embodiment of this utility model, in order to connect the first reinforcing bar 1 and the second reinforcing bar 2, the connector specifically includes a sleeve 31. The sleeve 31 has an internal thread 311, which cooperates with the long external thread 11 and the short external thread 21. The outer wall of the sleeve 31 has a sliding groove 312. The limiting sleeve 32 is penetrated by the second reinforcing bar 2 and fixedly connected to the second reinforcing bar 2. The limiting sleeve 32 has a limiting groove 321. The limiting rod 341 penetrates the first fixing sleeve 33 and the second fixing sleeve 34 and is slidably connected to the first fixing sleeve 33 and the second fixing sleeve 34. A spring is fixedly connected to the outer wall of the limiting rod 341 and elastically connected to the outer wall of the second fixing sleeve 34 through the spring. The first fixing sleeve 33 and the second fixing sleeve 34 are penetrated by the sleeve 31 and fixedly connected to the sleeve 31.

[0030] Furthermore, the sleeve 31 passes through the rotating sleeve 35 and is rotatably connected to the rotating sleeve 35. The outer wall of the rotating sleeve 35 is provided with an inclined groove 351. A positioning block 352 is fixedly connected to the lower outer wall of the rotating sleeve 35. A slider 342 is slidably connected to the inclined groove 351. The slider 342 is fixedly connected to the end of the limiting rod 341.

[0031] Furthermore, a sliding sleeve 36 is provided below the rotating sleeve 35. A protrusion 363 is fixed on the inner wall of the sliding sleeve 36. The protrusion 363 is slidably connected to the sliding groove 312. The sliding sleeve 36 has a positioning groove 1 361 and a positioning groove 2 362. The included angle between the positioning groove 1 361 and the positioning groove 2 362 is 30 degrees. A fixed sleeve 37 is provided below the sliding sleeve 36. The fixed sleeve 37 is fixedly connected to the outer wall of the sleeve 31. A spring is provided between the sliding sleeve 36 and the fixed sleeve 37.

[0032] In this utility model, during use, the limiting sleeve 32 is first welded to the outer wall of the second reinforcing bar 2. Then, the sleeve 31 is threadedly connected to the first reinforcing bar 1, and the end of the sleeve 31 is flush with the end of the first reinforcing bar 1. Next, the second reinforcing bar 2 is flush with the first reinforcing bar 1. Then, the sleeve 31 is screwed to make the sleeve 31 threadedly connected to the second reinforcing bar 2. At this time, the sleeve 31 will move towards the limiting sleeve 32. When the sleeve 31 moves a certain distance, the outer wall of the limiting sleeve 32 will connect with the end of the limiting rod 341. When the sleeve 31 is turned, the limiting rod 341 will be squeezed, causing the limiting rod 341 to move. At the same time, the spring will undergo elastic deformation. Then, during the process of turning the sleeve 31, the end of the limiting rod 341 will coincide with the limiting groove 321 opened on the limiting sleeve 32. At this time, the limiting rod 341 will spring into the limiting groove 321 under the elastic force of the spring, thereby limiting the sleeve 31, thereby improving the stability between the first rebar 1 and the second rebar 2, and preventing the sleeve 31 from sliding under the influence of external factors.

[0033] When it is necessary to separate rebar 1 and rebar 2, first pull the sliding sleeve 36 so that it slides along the groove 312. At this time, the positioning block 352, which is fixedly connected to the outer wall of the bottom end of the rotating sleeve 35, disengages from the positioning groove 361. The limit of the rotating sleeve 35 is released. Then, the rotating sleeve 35 is turned. During this process, the inclined groove 351 will squeeze the slider 342, causing the slider 342 to pull the limiting rod 341 to move. At this time, the limiting rod 341 will disengage from the limiting groove 321. It should be noted that when the slider 342 moves to the end of the inclined groove 351, the rotating sleeve 35 rotates at a 30-degree angle. At this time, the positioning block 352 will coincide with the positioning groove 362. Then, the sliding sleeve 36 is released so that the positioning block 352 is inserted into the positioning groove 362, thereby limiting the rotating sleeve 35 again. Then, the sleeve 31 is turned so that rebar 1 and rebar 2 are separated.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
