Description

Technical Field

[0001] This utility model relates to the field of beam clamp technology, and in particular to an adjustable beam clamp. Background Technology

[0002] Beam clamps are widely used tools in the construction and engineering fields, primarily for fixing and supporting beams or crossbeams to ensure that the beams do not affect other work or safety due to movement or shaking.

[0003] During assembly, the beam clamp uses a fixed clamping plate and a movable clamping plate to hold the crossbeam.

[0040] Thus, the bearing seat 21 is placed at the bottom of the crossbeam body 5, and the crossbeam body 5 is located between the fixed clamping plate 1 and the movable clamping plate 22. Then, the rotating wheel 23 is rotated by the rotating shaft 231, and the abutting plate 24 located on the outer periphery of the rotating wheel 23 abuts against the movable clamping plate 22. The locking member 25 is used to restrict the rotation of the rotating shaft 231, so that the movable clamping plate 22 and the fixed clamping plate 1 clamp the crossbeam body 5. This changes the traditional fixing method of fixing the movable clamping plate 22 by using wedges. While restricting the use position of the movable clamping plate 22, the abutting plate 24 is easy to disassemble.

[0041] Specifically, the fixed clamping plate 1 is machined with three limiting grooves. The fixed clamping plate 1 and the bearing seat 21 are arranged perpendicularly.

[0043] Specifically, the strip plate 251 connects the rotating shaft 231 and the handle 253 together. The outer wall of the positioning pin 252 is threaded. The positioning pin 252 is used to connect the strip plate 251 and the bearing seat 21 to limit the rotation of the rotating shaft 231 and lock the position of the clamping plate 24. The rubber sleeve on the outer periphery of the handle 253 is used to increase the friction between the hand and the handle 253. In addition, under the premise of braking the rotating shaft 231, the locking member 25 can also be replaced by other fixing structures.

[0044] In some embodiments, such as Figure 4 As shown, a spring-loaded assembly 3 is installed at the bottom of the movable clamping plate 22. The spring-loaded assembly 3 is used to drive the movable clamping plate 22 and the crossbeam body 5 to separate. The spring-loaded assembly 3 includes a mounting cylinder 31, a crossbar 32, a connecting plate 33 and an elastic element 34.

[0045] Specifically, the mounting cylinder 31 is located in the cavity of the bearing seat 21. The end of the crossbar 32 away from the connecting plate 33 is machined with a protruding disc. The connecting plate 33 connects the crossbar 32 and the movable clamping plate 22. Using the elastic potential energy of the elastic element 34, the movable clamping plate 22 and the crossbeam body 5 are separated to facilitate the disassembly of the bearing seat 21.

[0046] In some embodiments, such as Figure 5 As shown, an anti-detachment component 4 is installed at the top of the fixed clamping plate 1. The anti-detachment component 4 is used to increase the connection stability between the bearing seat 21 and the crossbeam body 5. The anti-detachment component 4 includes a support frame 41, a mounting plate 42, and a top pin 43. The bottom end of the support frame 41 is fixedly connected to the fixed clamping plate 1. The mounting plate 42 is equipped with bolts 421. The mounting plate 42 is connected to the support frame 41 by bolts 421. The top pin 43 is internally threaded to the mounting plate 42. The bottom end of the top pin 43 abuts against the crossbeam body 5.

[0048] In some embodiments, such as Figure 5 As shown, the support frame 41 is machined into a U-shape, and through holes are evenly distributed on both sides of the support frame 41.

[0049] Specifically, the support frame 41 is machined into a U-shape to constrain the vertical movement of the mounting plate 42. The through holes on both sides of the support frame 41 are used to connect with bolts 421 to fix the mounting plate 42 at different positions of the support frame 41.

[0050] In some embodiments, such as Figure 2 As shown, the fixed clamping plate 1 is equipped with a reinforcing rib 11, the bottom end of which is fixedly connected to the bearing seat 21, and the reinforcing rib 11 is machined into a triangle shape.

[0051] The reinforcing rib 11 is designed to increase the connection strength between the fixing plate 1 and the bearing seat 21.

[0052] In some embodiments, such as Figure 2 As shown, an anti-slip component 12 is installed in the limiting groove of the fixed clamping plate 1. The anti-slip component 12 includes a textured plate 121 and a pin 122. The textured plate 121 is located in the limiting groove of the fixed clamping plate 1 and is connected to the fixed clamping plate 1 through the pin 122.

[0053] There are three textured plates 121. The number of textured plates 121 used is adapted to the limiting groove of the fixing plate 1. Each textured plate 121 is provided with two pins 122. The outer wall of the pins 122 is threaded, and the textured plate 121 is provided with countersunk holes.

[0054] In some embodiments, such as Figure 5 As shown, the pins 122 are symmetrically distributed based on the textured plate 121.

[0056] In some embodiments, such as Figure 2 As shown, the support seat 21 is equipped with a limiting plate 211, which is compatible with the sliding groove of the movable clamping plate 22.

[0057] The limiting plate 211 is located on both sides of the bearing seat 21, and the limiting plate 211 allows the movable clamping plate 22 to move laterally.

[0058] In some embodiments, such as Figure 4 As shown, the elastic element 34 is a compression spring.

[0059] The elastic element 34 adopts a compression spring design, which facilitates the movement of the crossbar 32 in the mounting cylinder 31.

[0060] The working principle of this application is illustrated below with a preferred embodiment:

Then, the movable clamping plate 22 is moved along the outer wall of the bearing seat 21. The movable clamping plate 22 moves along the strip plate 251. At the same time, the connecting plate 33 at the bottom end of the movable clamping plate 22 drives the crossbar 32 to move. The crossbar 32 extends into the inner cavity of the mounting cylinder 31 and compresses the elastic element 34. The strip plate 251 clamps the other side of the crossbeam body 5. The handle 253 is rotated through the strip plate 251. 51 drives the rotating shaft 231 to rotate, the rotating shaft 231 drives the rotating wheel 23 to rotate, and then the top of the clamping plate 24 on the rotating wheel 23 abuts against the movable clamping plate 22. The positioning pin 252 in the rotating strip plate 251 is inserted into the threaded hole on the side wall of the bearing seat 21, thereby restricting the rotation of the rotating shaft 231. Then, the mounting plate 42 and the support frame 41 are connected by bolts 421. The top of the mounting plate 42 and the top of the crossbeam body 5 are set parallel to each other. The top pin 43 is rotated, and the top pin 43 abuts against the crossbeam body 5. The bearing seat 21 and the top pin 43 clamp the crossbeam body 5 from top to bottom.
