Description

Technical Field

[0001] This utility model relates to the field of clamps, specifically a clamp for installing road stone. Background Technology

[0002] In road construction, the clamps used for installing road stones are special tools used to hold and move road stones. Workers squeeze the lever arm to hold the stone through the clamps on the lever. However, the hand-held part at the upper end of the lever arm is generally fixed and not adjustable, which is inconvenient for workers of different heights to hold and use the clamps. Moreover, the clamps are in contact with the stone and are wear parts, making them inconvenient to replace.

[0003] Therefore, it is necessary to propose a clamp for installing road stone. Utility Model Content

[0004] The purpose of this utility model is to provide a clamp for installing road stone materials to solve the problems mentioned in the background art.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] likeFigures 1-4 ;

[0023] A road stone installation clamp includes a first clamping arm 1 and a second clamping arm 11, which are hinged at the middle. An adjustment component 2 is provided at the upper end of the first clamping arm 1 and the second clamping arm 11, which can adjust the position of the road stone clamp handle. A clamping head component 3 is provided at the lower end of the first clamping arm 1 and the second clamping arm 11, which facilitates the disassembly and replacement of the lower end of the road stone clamp.

[0024] Furthermore, the adjustment assembly 2 includes a turntable 21, a first connecting arm 22, and a second connecting arm 23. The turntable 21 is rotatably mounted on the upper ends of both the first clamping arm 1 and the second clamping arm 11. Rotating the turntable 21 simultaneously rotates the first connecting arm 22 and the second connecting arm 23 to adjust their angle positions. The first connecting arm 22 is welded to one side of the turntable 21, and the second connecting arm 23 is welded to the other side. Both the first connecting arm 22 and the second connecting arm 23 can be used to connect the connecting rod 25. The turntable 21 has evenly spaced second threaded holes 28 for installing bolts, ensuring that the turntable 21 on the first clamping arm 1 and the second clamping arm 11 rotates at the same angle, allowing the installation angle of the connecting rod 25 to be adjusted. The bolts are threaded to the inner walls of the first clamping arm 1 and the second clamping arm 11. The bolts are threaded from one side of the turntable 21 and then threaded to the first clamping arm 1 and the second clamping arm 11. The inner wall of the two clamping arms 11 is finally connected to the other side of the turntable 21 by bolt threads. The turntable 21 is fixed in position after rotation by two bolts. The upper ends of the first connecting arm 22 and the second connecting arm 23 are provided with first threaded holes 24 at equal intervals. The connecting rod 25 is installed in the internal thread of the first threaded hole 24. Since there are multiple first threaded holes 24, the position of the connecting rod 25 installed on the first connecting arm 22 and the second connecting arm 23 can be adjusted according to actual use needs to meet the needs of people of different heights. The installation position of the connecting rod 25 can be adjusted according to individual needs to make the clamp more convenient and labor-saving during use. The outer wall of the connecting rod 25 is covered with a rubber sleeve 26, which protects the hand and prevents the connecting rod 25 from rubbing against the hand. The rear end of the connecting rod 25 is welded with a rear handle 27, which is also used for hand gripping. The choice of use depends on the actual environment.

[0025] Furthermore, the clamp assembly 3 includes a U-shaped connecting block 31, a connecting head 32, and a U-shaped support plate 33. The lower ends of both the first clamping arm 1 and the second clamping arm 11 are welded with U-shaped connecting blocks 31. The U-shaped connecting blocks 31 are used to connect to the connecting head 32, which is hinged within the U-shaped connecting block 31. The connecting head 32 supports and connects to the U-shaped support plate 33, allowing the U-shaped support plate 33 to rotate and adjust its position. The U-shaped support plate 33 is welded to the connecting head 32, and it supports and installs the clamping plate 34. The clamping plate 34 is snapped into the inner side of the U-shaped support plate 33 and fixed by bolt thread connection. This allows for easy disassembly and replacement of the clamping plate 34. The clamping plate 34 can be selected in different lengths according to usage requirements. The clamping plate 34 has a groove 36, which will fit more closely when clamping the stone, thereby increasing the clamping force and making the stone more firmly fixed on the clamp, preventing it from loosening and falling off during the clamping process. The bottom of the first clamping arm 1 and the second clamping arm 11 are both connected to a spring 35. The other end of the spring 35 is connected to the connector 32. The spring 35 is used to pull the connector 32. When the clamping plate 34 releases the stone, the spring 35 pulls the connector 32 to rotate, so that the U-shaped support plate 33 and the clamping plate 34 return to their original positions.

[0026] The working principle of this utility model is as follows: A turntable 21 is rotatably mounted on the upper ends of both the first clamping arm 1 and the second clamping arm 11. Rotating the turntable 21 simultaneously rotates the first connecting arm 22 and the second connecting arm 23 to adjust their angles and positions. After the turntable 21 rotates, bolts are threaded onto one side of the turntable 21, then threaded onto the inner walls of the first clamping arm 1 and the second clamping arm 11, and finally threaded onto the other side of the turntable 21. The two bolts fix the position of the rotated turntable 21. First threaded holes 24 are equidistantly provided at the upper ends of both the first connecting arm 22 and the second connecting arm 23. The connecting rod 25 can be adjusted according to actual usage requirements and installed on both the first connecting arm 22 and the second connecting arm 23. Position 23 accommodates users of different heights, making it more convenient and effortless to use. Connector 32 is hinged inside U-shaped connecting block 31, and U-shaped support plate 33 is welded to connector 32. Clamping plate 34 is snapped onto the inner side of U-shaped support plate 33 and fixed by bolt thread connection, making clamping plate 34 easy to disassemble and replace. Clamping plate 34 can be selected in different lengths according to usage requirements. The clamping plate 34 has a groove 36, which will fit better when clamping the stone, thereby increasing the clamping force and fixing the stone more firmly on the clamp, preventing it from loosening and falling off during the clamping process. When clamping plate 34 releases the stone, spring 35 pulls connector 32 to rotate, so that U-shaped support plate 33 and clamping plate 34 return to their original positions.

[0027] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
