[0001] The utility model relates to the technical field of building construction, in particular to a handheld steel bar bending device. Background Art

[0002] In the modern construction field, reinforced concrete structures have become the mainstream due to their excellent load-bearing capacity and durability. As the "skeleton" of concrete structures, the precise layout and shape of steel bars are crucial for the overall strength of buildings.

[0018] (III) Beneficial effects

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. A hand-held steel bar bending device of the present utility model can clamp the wall through the clamping device, so as to accurately position the wall, make the device stably placed on the wall, so that the pushing device can push the steel bar on the wall. When the bending center of the steel bar is inside the wall, the pushing device can still push the steel bar, thereby realizing the destruction of the wall to bend the steel bar, so that it is no longer necessary for manual labor to use a round pipe to break the wall and bend the steel bar with the bending center inside the wall. Furthermore, the working efficiency of bending the steel bar is improved, more time is saved, the labor cost is reduced, and at the same time, the safety of the manual labor is improved. The present utility model makes the steel bar with the bending center inside the wall bend through the coordinated work of the clamping device and the pushing device, thereby realizing the breaking of the wall and bending of the steel bar, and improving the working efficiency and safety.

[0021] 2. A hand-held steel bar bending device of the present utility model ensures that the wall can be accommodated in the base by providing a receiving groove on the base, and then clamps the wall through the cooperation of the pushing member and the reference wall, so that the pushing device can accurately bend the steel bar at a predetermined position. Moreover, since there is an included angle between the pushing end of the pushing device and the extension line of the pushing member, it can convert the vertically placed steel bar into a bent state parallel to the thickness direction of the wall, thus avoiding the situation where the steel bar cannot be bent to be parallel to the thickness of the wall, thereby improving work efficiency and completion accuracy. By setting the pushing space as a horizontal section and a vertical section, it is adapted to the vertical state and the bent state of the steel bar, thus avoiding the inability to bend the steel bar. By providing a driving member and a push rod, the driving member can drive the push rod to expand and contract, enabling the push rod to push the vertically placed steel bar into a bent state. Moreover, the push rod can push the steel bar to any angle between it and the vertical plane, thereby improving the applicability of the device. When the push rod is driven by the driving member to retract, it can immediately return to the initial state for subsequent bending of the remaining vertically placed steel bars, improving work efficiency.

[0022] 3. A hand-held steel bar bending device of the present utility model can limit the steel bar by providing a limiting groove at the pushing end of the push rod, so that when the push rod pushes the steel bar, there is no relative displacement between the push rod and the steel bar, improving stability. By setting the inner wall of the limiting groove on the side facing the driving member as an inclined wall, it can increase the contact area with the outer wall of the steel bar, enhance the force when the steel bar changes from the vertical state to the bent state, and make the steel bar easier to transform, thereby improving work efficiency. By setting the top of the inclined wall as an arc structure, it can adapt to the change in the angle of the steel bar in the bent state, thus always pushing the steel bar to be bent, making the applicability of the push rod stronger.

[0023] 4. A hand-held steel bar bending device of the present utility model is provided with an abutting block, a threaded rod, and a rotating handle respectively. The rotating handle can drive the threaded rod and the abutting block to rotate synchronously, so that the threaded rod moves horizontally along its own axis towards or away from the wall, so as to realize the cooperation of the abutting block and the reference wall to clamp the wall, so that the wall is stably placed in the receiving groove and the device is prevented from falling. By providing an anti-slip pad on the abutting block, it can enhance the friction between the abutting block and the wall, making the abutting block more stable when clamping the wall in cooperation with the base. By providing anti-slip lines on the reference wall, it can enhance the friction between the reference wall and the wall, making the wall more stable when being clamped.

[0024] 5. A handheld steel bar bending device of the present utility model is provided with a gasket on the bottom wall of the receiving groove. When the wall is placed into the receiving groove, the gasket can exert a buffering force on the wall, and at the same time separate the base from the wall, avoiding rigid contact between the base and the wall and causing damage to the base. By providing a handle, the operator can more conveniently hold and move the device, improving the controllability and flexibility of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] In order to better understand the above technical solutions, the exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided so that the present utility model can be understood more clearly and thoroughly, and the scope of the present utility model can be completely conveyed to those skilled in the art.

[0033] Embodiment 1

[0034] As Figures 1 - 5As shown in the figure, a hand-held steel bar bending device according to this embodiment is applicable to a wall 3 with a steel bar 4, and a part of the steel bar 4 extends out from the side of the wall 3. The hand-held steel bar 4 bending device includes a clamping device 1 and a pushing device 2.

[0035] Among them, the clamping device 1 can switch between a clamping state of clamping the wall 3 and a releasing state of releasing the wall 3. The pushing device 2 is connected to the clamping device 1. When the clamping device 1 is in the clamping state, the pushing end of the pushing device 2 can extend from the initial position to the pushing position to push the part of the steel bar 4 extending out of the wall 3 to bend relative to the wall 3. By setting the clamping device 1, it can clamp the wall 3 for accurate positioning of the wall 3, so that the device can be stably placed on the wall 3, so that the pushing device 2 can push the steel bar 4 on the wall 3. When the bending center of the steel bar 4 is inside the wall 3, the pushing device 2 can still push the steel bar 4, so as to realize breaking the wall 3 to bend the steel bar 4, so that it is no longer necessary to manually use a round pipe to break the wall and bend the steel bar 4 with the bending center inside the wall 3, thereby improving the working efficiency of bending the steel bar 4, saving more time, reducing the labor cost, and at the same time, improving the safety of the workers.

[0036] Further, the clamping device 1 includes a base 11 and a pushing member 12. The base 11 has a receiving groove 111 capable of receiving the wall 3. One side wall of the receiving groove 111 is a reference wall 113 for the wall 3 to abut against. The pushing member 12 horizontally passes through the other side wall of the receiving groove 111 and is screwed to the side wall. The pushing member 12 can rotate bidirectionally and horizontally move along its own axis toward or away from the reference wall 113 to cooperate with the reference wall 113 to clamp or release the wall 3. By providing the receiving groove 111 on the base 11, it can ensure that the wall 3 can be received in the base 11, and then the clamping of the wall 3 is realized through the cooperation of the pushing member 12 and the reference wall 113, so that the pushing device 2 can accurately bend the steel bar 4 at a predetermined position, and it can also make the positioning of the wall 3 unified each time. The fixed end of the pushing device 2 is fixedly installed on the base 11 and is located below the pushing member 12. There is an included angle between the telescopic extension line of the pushing end of the pushing device 2 and the extension line of the pushing member 12, which can realize converting the vertically state steel bar 4 into a bent state parallel to the thickness direction of the wall 3, so as to avoid the situation that the steel bar 4 cannot be bent to be parallel to the thickness of the wall 3, thereby improving the working efficiency and the completion accuracy. The pushing end passes through the base 11 during the process of switching between the initial position and the pushing position. The clamping device 1 and the pushing device 2 cooperate to be able to bend the steel bar 4 to be parallel to the thickness direction of the wall 3. Preferably, the reference wall 113 is provided with anti-slip lines, which can enhance the friction between the reference wall 113 and the wall 3 and make the wall 3 more stable when being clamped.

[0037] Further, a gasket 5 is provided on the bottom wall of the receiving groove 111. The top wall of the gasket 5 can be attached to the bottom wall of the wall body 3. When the wall body 3 is placed into the receiving groove 111, the gasket 5 applies a buffering force to the wall body 3, and at the same time separates the base 11 from the wall body 3, avoiding rigid contact between the base 11 and the wall body 3 and causing damage to the base 11.

[0038] Further, the receiving groove 111 is provided at the top of the base 11. On one side of the base 11 relative to the pushing member 12, there is a pushing space 112 for receiving the steel bar 4. The pushing space 112 includes a vertical section and a horizontal section. The two ends of the vertical section respectively penetrate the top and bottom of the base 11 and communicate with the receiving groove 111. The horizontal section penetrates the side wall of the base 11 away from the receiving groove 111. By setting the pushing space 112 as a horizontal section and a vertical section, it is adapted to the vertical state and the bent state of the steel bar 4, thus avoiding the inability to bend the steel bar 4. At the bottom of the base 11, there is a telescopic channel for the pushing end of the pushing device 2 to stretch. The pushing space 112 communicates with the receiving groove 111 and the telescopic channel respectively. The pushing device 2 includes a driving member 21 and a push rod 22. The fixed end of the driving member 21 is fixedly installed on the base 11 and is located below the pushing member 12. The fixed end of the push rod 22 is connected to the output end of the driving member 21. The pushing end of the push rod 22 constitutes the pushing end of the pushing device 2. The driving member 21 can drive the push rod 22 to stretch and retract, so that the pushing end of the push rod 22 can be switched between the initial position and the pushing position. By setting the driving member 21 and the push rod 22, the driving member 21 can drive the push rod 22 to stretch and retract, enabling the push rod 22 to push the vertically placed steel bar 4 to the bent state, and moreover, the push rod 22 can push the steel bar 4 to any angle between it and the vertical plane, thereby improving the applicability of the equipment. When the push rod 22 is driven by the driving member 21 to retract, the push rod 22 can immediately return to the initial state, so as to bend the remaining vertically placed steel bars 4 subsequently and improve the working efficiency.

[0039] Further, a limiting groove 221 for receiving the steel bar 4 is provided at the pushing end of the push rod 22. The steel bar 4 is attached to the inner wall of the limiting groove 221, which can limit the steel bar 4, so that when the push rod 22 pushes the steel bar 4, there is no relative displacement between the push rod 22 and the steel bar 4, improving the stability. Preferably, the inner wall of the limiting groove 221 facing the driving member 21 is an inclined wall 2211 inclined relative to the telescopic direction of the push rod 22. The inclined wall 2211 is parallel to the axis of the vertically placed steel bar 4, which can increase the contact area with the outer wall of the steel bar 4, enhance the force when the steel bar 4 changes from the vertical state to the bent state, and make the steel bar 4 change more easily, thus improving the working efficiency. The inclined wall 2211 is an arc structure 2212, which can adapt to the change of the angle of the steel bar 4 in the bent state, and thus always push the steel bar 4 to be bent, making the applicability of the push rod 22 stronger.

[0040] Further, the pushing member 12 includes a pushing block 121, a threaded rod 122, and a rotating handle 123. The pushing block 121, the threaded rod 122, and the rotating handle 123 are connected in sequence from left to right, and the pushing block 121 is placed in the receiving groove 111. The pushing block 121 can cooperate with the reference wall 113 to clamp the wall body 3. The threaded rod 122 passes through the base 11 and is screwed with the base 11. The rotating handle 123 can rotate and drive the threaded rod 122 to rotate, so that the threaded rod 122 drives the pushing block 121 to rotate and move horizontally along the axis of the threaded rod 122 in a direction close to or away from the wall body 3, so as to cooperate with the reference wall 113 to clamp or loosen the wall body 3, so that the wall body 3 is stably placed in the receiving groove 111 to prevent the device from falling. Preferably, an anti-slip pad 124 is provided on the side wall of the pushing block 121 facing the wall body 3, which can enhance the friction between the pushing block 121 and the wall body 3, making the pushing block 121 more stable when clamping the wall body 3 in cooperation with the base 11.

[0041] Further, the steel bar 4 bending device further includes a handle 6. One end of the handle 6 is fixedly installed on the outer wall of the base 11, and the other end is fixedly installed on the driving member 21. The two ends of the handle 6 are located on the same side, so that the operator can hold and move the device more conveniently, improving the controllability and flexibility of the device.

[0042] With the above structure, the working principle of a hand-held steel bar bending device according to this embodiment is as follows: As Figure 1 shown, first assemble the device. After the assembly is completed, place the base 11 under the wall body 3, and place the wall body 3 in the receiving groove 111. The bottom wall of the wall body 3 is attached to the top wall of the gasket 5, and the side wall of the wall body 3 away from the pushing member 12 is attached to the anti-slip pattern. Then rotate the rotating handle 123 to drive the threaded rod 122 to rotate, and drive the pushing block 121 to push against the side wall of the wall body 3 close to the pushing member 12, and cooperate with the base 11 to clamp the wall body 3. At this time, the steel bar 4 is located in the limiting groove 221, and the inclined wall of the push rod 22 is attached to the outer wall of the vertically placed steel bar 4. Then drive the driving member 21 to drive the push rod 22 to extend, thereby pushing the vertically placed steel bar 4. During the process of the push rod 22 pushing the steel bar 4, the outer wall of the steel bar 4 is attached to the inclined wall in the limiting groove 221 and gradually changes to the arc-shaped structure 2212 at the top of the inclined wall being attached to the outer wall of the steel bar 4, so that the steel bar 4 is bent between 0° and 90°.

[0043] After the bending of one steel bar 4 is completed, drive the driving member 21 to drive the push rod 22 to retract to the initial state. Then, rotate the rotating handle 123 in the reverse direction to move the pushing block 121 in a direction away from the wall body 3, so that the device is in the initial state.

[0044] When it is necessary to bend the next steel bar 4, the above process is continuously repeated to complete the bending of the steel bar 4, and details are not described herein again.
