[0004] This patent allows for convenient and simple straightening of reinforcing bars. However, with existing devices, if the fixed threaded rod becomes loose during the straightening process, the reinforcing bars may loosen, thus affecting the straightening effect and the stability of the structure.

[0005] Therefore, we propose a novel rebar straightening device for building construction. Utility Model Content

[0006] The purpose of this invention is to solve the problem that when existing devices are used to straighten reinforcing bars, if the fixed threaded rod becomes loose, the reinforcing bars will loosen during the straightening process, thus affecting the straightening effect and the stability of the structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a rebar straightening device for building construction, comprising a fixed box, a fixing and anti-loosening clamping assembly connected to the front surface of the fixed box, the fixing and anti-loosening clamping assembly comprising a support frame, the support frame having four sets of threaded holes annularly formed on its surface, each set of threaded holes having a positioning groove on both sides, each set of threaded holes having a threaded rod inside, the rear end of the threaded rod being connected to a handle, the front end of the threaded rod being connected to a bearing body, the front end of the bearing body being connected to a connecting block, the connecting block having a spring inside, one side of the spring being connected to a top block, one side of the top block being connected to a clamping plate, and both sides of the clamping plate having positioning blocks connected to them.

[0008] Furthermore, the position and size of the positioning block match the position and size of the positioning groove, and a sliding connection is formed between the positioning block and the positioning groove.

[0009] Furthermore, the surface of the clamping plate is arc-shaped, the threaded rod and the threaded hole form a threaded connection, and the top block and the spring form an elastic structure.

[0010] Furthermore, a lifting assembly is connected to the bottom of the fixed housing. The lifting assembly includes a base, a servo motor is connected to the front surface of the base, and a connecting rod is inserted into the surface of the base.

[0013] Furthermore, a bearing sleeve is fitted onto the surface of the one-way screw near the second gear, threaded blocks are connected to the surfaces of both sets of one-way screws, and sliders are connected to the four bottom corners of the fixed housing.

[0014] Furthermore, each of the four corners of the base surface is connected to a slide rail, the slider is T-shaped, and the slider and the slide rail form a sliding connection.

[0015] Furthermore, the two sets of one-way screws are threadedly connected to the two sets of threaded blocks, and the bearing sleeve is rotatably connected to the one-way screws.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, when straightening reinforcing bars, the reinforcing bars can be inserted into the fixed box, and then the threaded rod can be rotated to clamp the reinforcing bars by thread fixing. The positioning block slides in the positioning groove to improve the stability when the clamping plate descends. When the threaded rod becomes loose, the spring will push the top block with its own elastic force to drive the clamping plate to continue clamping the reinforcing bars, so as to avoid the threaded rod becoming loose when clamping, which would affect the straightening effect and the stability of the structure.

[0018] 2. In this utility model, when operators of different heights are performing rebar straightening operations, the servo motor can be turned on to drive the first gear to rotate, thereby driving the two sets of threaded blocks to adjust their height simultaneously through the meshing and rotation of the gears. As the threaded blocks rise and fall, the height of the fixed box is adjusted, which improves the applicability of the fixed box and avoids the problem of inconvenience for operators of different heights when performing operations.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, such as Figure 1 - Figure 3 As shown, this utility model provides a rebar straightening device for building construction, including a fixed box 1. A fixing and anti-loosening clamping assembly 2 is connected to the front surface of the fixed box 1. The fixing and anti-loosening clamping assembly 2 includes a support frame 201. Four sets of threaded holes 202 are circumferentially formed on the surface of the support frame 201. Positioning grooves 203 are formed on both sides of each set of threaded holes 202. A threaded rod 204 is provided inside each set of threaded holes 202. A handle 205 is connected to the rear end of the threaded rod 204, and a bearing body 206 is connected to the front end of the threaded rod 204. The front end of the bearing body 206... A connecting block 207 is connected, and a spring 208 is connected inside the connecting block 207. A top block 209 is connected to one side of the spring 208, and a clamping plate 210 is connected to one side of the top block 209. Positioning blocks 211 are connected to both sides of the clamping plate 210. The position and size of the positioning blocks 211 match the position and size of the positioning groove 203. The positioning blocks 211 and the positioning groove 203 form a sliding connection. The surface of the clamping plate 210 is arc-shaped. The threaded rod 204 and the threaded hole 202 form a threaded connection. The top block 209 and the spring 208 form an elastic structure.

[0029] The overall effect of Embodiment 1 is as follows: When straightening the reinforcing bar, the reinforcing bar can be inserted between the four sets of clamping plates 210. Then, the handle 205 can be rotated to drive the threaded rod 204 to rotate, so that the threaded rod 204 can rotate with the support frame 201 through the threaded hole 202, and push the clamping plate 210 to move downward. As the clamping plate 210 moves downward, it also drives the positioning block 211 to slide in the positioning groove 203, improving the stability of the clamping plate 210 when it descends, and realizing the clamping of the reinforcing bar. At this time, the spring 208 is also in a compressed state. After the reinforcing bar is fixed, the telescopic controller of the fixing box 1 can be opened to drive the pressure block to perform the straightening operation on the reinforcing bar. When a set of threaded rods 204 becomes loose, the spring 208 will push the top block 209 through its own elastic force to drive the clamping plate 210 to continue clamping the reinforcing bar, so as to prevent the threaded rod 204 from becoming loose during clamping.

[0030] After the steel bar is straightened, the handle 205 can be turned in the opposite direction so that the threaded rod 204 can drive the clamp 210 away from the steel bar, and then the straightened steel bar can be pulled out.

[0031] Example 2, as Figures 4-6 As shown, a lifting assembly 3 is connected to the bottom of the fixed housing 1. The lifting assembly 3 includes a base 301, a servo motor 302 connected to the front surface of the base 301, a connecting rod 303 inserted into the surface of the base 301, first gears 304 connected to both sides of the connecting rod 303, support plates 305 connected to both sides of the base 301, bearing sleeves 306 connected inside the two sets of support plates 305, one-way screws 307 inserted into the inside of the bearing sleeves 306, and a second gear 308 connected to the bottom end of the one-way screws 307. A bearing sleeve 306 is fitted onto the surface of the one-way screw 307 near the second gear 308. Threaded blocks 309 are connected to the surfaces of both sets of one-way screws 307. Slider blocks 310 are connected to the four corners of the bottom of the fixed housing 1. Slide tracks 311 are connected to the four corners of the surface of the base 301. The slider 310 is T-shaped. The slider 310 and the slide track 311 form a sliding connection. The two sets of one-way screws 307 and the two sets of threaded blocks 309 form a threaded connection. The bearing sleeve 306 and the one-way screw 307 form a rotating connection.

[0032] The effect achieved by the entire embodiment 2 is that when it is necessary to raise the height of the fixed housing 1, the reverse rotation function of the servo motor 302 can be activated by the control switch, thereby enabling the connecting rod 303 to drive the two sets of first gears 304 to rotate in reverse. At the same time, the two sets of first gears 304 will also drive the two sets of second gears 308 to rotate in reverse, thereby enabling the two sets of second gears 308 to drive the two sets of one-way screws 307 to rotate in reverse. This allows the two sets of one-way screws 307 to rotate in reverse with the two sets of threaded blocks 309 simultaneously. This reverse rotation drives the threaded blocks 309 to move upward, and the upward movement of the threaded blocks 309 will also push the fixed housing 1 to move upward. When body 1 rises, it also causes slider 310 to slide within slide rail 311, improving the stability of fixed housing 1 during lifting and lowering. When the height of fixed housing 1 reaches a suitable position, servo motor 302 can be turned off. When it is necessary to lower the height of fixed housing 1, the forward rotation function of servo motor 302 can be activated to drive connecting rod 303 to rotate forward. This, through gear meshing, drives two sets of one-way screws 307 to rotate forward, thereby enabling two sets of threaded blocks 309 to rotate forward simultaneously, thus driving fixed housing 1 to move downward and lowering the height of fixed housing 1. This is suitable for operators of different heights, avoiding the problem of inconvenience for operators of different heights during operation.

[0033] Working principle: When straightening reinforcing bars, the reinforcing bars can be inserted into the fixed box 1, and then the threaded rod 204 is rotated to clamp the reinforcing bars through threaded fixing. The positioning block 211 slides in the positioning groove 203, improving the stability of the clamping plate 210 when it descends. When the threaded rod 204 becomes loose, the spring 208 will push the top block 209 through its own elastic force, causing the clamping plate 210 to continue clamping the reinforcing bars, preventing the threaded rod 204 from becoming loose during clamping, which would affect the straightening effect and the stability of the structure. This allows for adjustments based on the height of the operator. When performing rebar straightening, the forward rotation function of the servo motor 302 can be activated to drive the connecting rod 303 to rotate forward. This, in turn, drives the two sets of one-way screws 307 to rotate forward through the meshing of gears. Consequently, the two sets of threaded blocks 309 can rotate simultaneously through the forward threads, thus moving downward through the forward thread rotation. This, in turn, drives the fixed housing 1 to move downward. As the threaded blocks 309 rise and fall, the height of the fixed housing 1 can be adjusted, improving the applicability of the fixed housing 1 and avoiding the problem of inconvenience for operators of different heights.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
