Adjustable steel bar tensioning clamp

Abstract

This utility model discloses an adjustable rebar tensioning clamp, including a connecting component and an installation component. The front surface of the installation component is provided with an installation notch, which extends through the installation component from front to back. The lower surface of the installation notch is open. A first compression seat is provided on one side of the installation notch, and a second compression seat is provided on the other side of the installation notch. Both the first and second compression seats can move up and down along the installation notch via the connecting component. This solution solves the problems of existing rebar tensioning clamps that use a disc-type snap-fit ​​connection for connection and up and down pushing, which limits the adjustment range of the connection position, resulting in a small adjustment range, low applicability to rebar sizes, and high replacement costs due to the non-detachable design.

Description

Technical Field

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

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece or guide a cutting tool. Its core function is to ensure machining accuracy and production efficiency. When stretching steel bars, a fixture is used to fix the steel bars.

[0003] For example, Chinese Patent CN220819646U (A Rebar Tensioning Clamp): includes a tensioning component, the top of which has a slot, the top of which has an installation groove, and the top of which has an installation block. This rebar tensioning clamp clamps the rebar by engaging it between two clamping bodies using a V-shaped jaw, thus enabling the device to clamp the rebar. After clamping, the round cover can be opened through a handle slot on the top of the round cover, and a measuring tape placed on the inner wall of the groove can be taken out. The measuring tape can then measure the clamped rebar and record the measurement data. After the quantity is measured, the measuring tape can be placed on the inner wall of the groove. If the pressure sensor does not detect a change in pressure, it will send a signal, causing the round cover to sound an alarm, thus serving as a warning and effectively preventing the measuring tape from being lost, thereby improving the practicality of the device.

[0004] However, existing rebar tension clamps use a disc-type snap-fit ​​connection for connection and vertical pushing, which limits the range of adjustment of the connection position, resulting in a small adjustment range, low applicability to rebar sizes, and the overall non-detachable form, making it difficult to perform partial replacements and leading to high replacement costs. Therefore, they do not meet the current requirements. To address this, we propose an adjustable rebar tension clamp. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable rebar tension clamp to solve the problems mentioned in the background art. The existing rebar tension clamp uses a disc-type snap-fit ​​connection for connection and up-and-down pushing, which limits the adjustment range of the connection position, resulting in a small adjustment range, low applicability of rebar size, and the fact that the whole is not detachable, making it difficult to replace parts and resulting in high replacement costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable rebar tensioning clamp, comprising: a connecting component, an installation component disposed on the outside of the connecting component, an installation notch disposed on the front surface of the installation component, the installation notch penetrating the installation component from front to back, and the lower surface of the installation notch being open, a first compression seat disposed on one side inside the installation notch, a second compression seat disposed on the other side inside the installation notch, and both the first compression seat and the second compression seat being movable up and down along the installation notch via the connecting component.

[0007] Preferably, the inner walls on both sides of the mounting notch are provided with a first adjustment groove, and the inclined surfaces of the first and second pressing seats are provided with a first adjustment seat, and the first adjustment seat slides along the first adjustment groove.

[0008] Preferably, the connecting assembly includes a connecting plate, and a second adjusting seat is provided on the lower surface of both sides of the connecting plate. A second adjusting groove is provided on the upper surface of both the first pressing seat and the second pressing seat, and the second adjusting seat slides along the second adjusting groove.

[0009] Preferably, the connecting assembly further includes a connecting seat, the connecting disc is provided with a ball bearing inside, and the connecting seat is rotatably connected to the connecting disc through the ball bearing. A threaded rod is provided at the center of the upper surface of the connecting seat, and handles are provided on both sides of the top end of the threaded rod.

[0010] Preferably, the mounting assembly includes a first front mounting plate, a second front mounting plate is disposed on one side of the first front mounting plate, and a first rear mounting plate and a second rear mounting plate are respectively disposed aligned with the rear of the first and second front mounting plates. The front surfaces of the first front mounting plate, the second front mounting plate, the first rear mounting plate, and the second rear mounting plate are all provided with mounting holes, and the mounting holes penetrate the first and second front mounting plates. The front ends of the mounting holes are provided with fixing bolts, and the first and second front mounting plates are fixed to the first and second rear mounting plates respectively by fixing bolts.

[0011] Preferably, the mounting assembly further includes a center seat, which is located between the first mounting front plate and the second mounting front plate, and fixing plates are welded to both the front and rear surfaces of the center seat.

[0012] Preferably, the upper surface of the center seat is provided with a threaded groove, and the threaded groove extends through the center seat from top to bottom.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model improves the range of motion and thus the adjustment range by using the second adjustment seat to slide along the second adjustment groove for the connecting plate instead of the existing disc-type snap-fit ​​method. This makes it suitable for steel bars of different sizes and improves its applicability. The first and second front mounting plates are fixed to the first and second rear mounting plates respectively by fixing bolts. The center seat is fixed to the first front mounting plate, the second front mounting plate, the first rear mounting plate and the second rear mounting plate respectively by external bolts at both ends of the two fixing plates, forming a connecting assembly. This facilitates disassembly and partial replacement, improves convenience and reduces replacement costs. It solves the problem that the existing steel bar tension clamp uses a disc-type snap-fit ​​method for connection and up and down pushing, which limits the adjustment range of the connection position, resulting in a small adjustment range, low applicability of steel bar size, and the overall non-detachable form, making it difficult to perform partial replacement and resulting in high replacement costs.

[0015] (2) By setting a first adjusting seat on the inclined surface of both the first extrusion seat and the second extrusion seat, the first adjusting seat slides along the first adjusting groove when the first extrusion seat and the second extrusion seat move. The first adjusting seat, the first adjusting groove, the second adjusting seat and the second adjusting groove are all T-shaped, which improves the sliding stability and makes it less likely to separate and fall off.
