[0035] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments, but the scope of protection claimed in the utility model is not limited to the following specific embodiments.

[0036] Embodiment 1:

[0037] refer to Figure 1 and Figure 2 A clamping lock structure includes a support arm 11, a support splint 12 and a support column 31. The support splint 12 is fitted with the support arm 11, and a non-slip pad 13 is fixedly connected to the side of the support splint 12 away from the support arm 11.

[0038] The support arm 11 is fixedly connected with a support seat 21, the support seat 21 is clamped with the support clamp plate 12, the support seat 21 is slidably connected with a bayonet 22, the support clamp plate 12 is provided with a clamping groove 23 matched with the bayonet 22, the support arm 11 is provided with a support groove 32, the support column 31 is penetrated through the support clamp plate 12 and inserted into the support groove 32, and the support column 31 is clamped with one end of the bayonet 22 away from the clamping groove 23. An elastic member 24 is provided between the support seat 21 and the bayonet 22, and the elastic member 24 is a spring whose two ends are respectively fixedly connected with the support seat 21 and the bayonet 22. The bayonet 22 is provided with a first inclined surface 25, and the support column 31 is provided with a second inclined surface 26 abutting against the first inclined surface 25, and one end of the first inclined surface 25 close to the support column 31 is inclined toward the support groove 32. The support seat 21 fits with the support column 31.

[0039] The support column 31 is provided with a fixed shaft 41, which is rotatably connected to the support column 31 and axially linked, and the support column 31 is fixedly connected with a screw 42, which is threadedly connected to the support arm 11. The support column 31 is fixedly connected with a clamping plate 43, which is clamped with the support clamping plate 12. The clamping plate 43 is fixedly connected with an anti-skid pad 44 flush with the anti-skid pad 13. The anti-skid pad 44 is provided with a through groove 45, and the fixed shaft 41 is fixedly connected with a hexagon socket screw head 46 located at the through groove 45. The fixed shaft 41 is fixedly connected with a snap ring 47, which is clamped with the support column 31 in the axial direction. The support column 31 is provided with a avoidance groove 33 located at the screw 42.

[0040] This embodiment has the following advantages:

[0041] When the anti-skid pad 13 needs to be replaced and maintained, the support column 31 is taken out from the support groove 32 and the state of the support column 31 and the bayonet 22 is released, so that the bayonet 22 slides out of the bayonet 23 under the push of the elastic member 24, so that the support splint 12 can slide out of the support seat 21, so that the support splint 12 and the anti-skid pad 13 can be removed, and then the anti-skid pad 13 can be conveniently maintained, achieving the advantage of convenient maintenance and clamping. The new support splint 12 and the anti-skid pad 13 are installed on the support seat 21, and the support seat 21 provides a supporting force for the support splint 12 and the anti-skid pad 13, and then the support column 31 is inserted into the support groove 32, so that the support seat 21 pushes the bayonet 22 to insert into the bayonet 23, so that the support splint 12 is locked by the bayonet 22, which ensures that the support splint 12 can be stably installed on the support arm 11, and the anti-skid pad 13 is conveniently replaced.

[0042] The fixed shaft 41 is rotated, and the fixed shaft 41 drives the screw 42 to rotate. The screw 42 rotates and moves axially on the support arm 11 threadedly connected to it. The screw 42 drives the support column 31 to move into the support groove 32 through the fixed shaft 41 until the support column 31 is engaged with the support arm 11. The screw 42 is tightened by the fixed shaft 41, so that the support column 31 can be locked on the support arm 11, thereby fixing the support column 31.

[0043] The clamping plate 43 clamps the support clamping plate 12 to prevent the support clamping plate 12 from accidentally sliding off the support seat 21 , thereby improving the stability of the support clamping plate 12 .

[0044] By arranging the anti-skid pad 44 on the clamping plate 43, the anti-skid pad 44 can provide friction to the goods, thereby preventing the goods from accidentally sliding when being clamped.

[0045] The hexagon socket screw head 46 is rotated by the hexagon socket wrench, so that the hexagon socket screw head 46 and the fixed shaft 41 can be rotated using common maintenance tools, which facilitates the driving of the fixed shaft 41 to rotate.

[0046] During the axial movement of the fixed shaft 41 , the support column 31 is driven to move axially through the clamping ring 47 , thereby realizing the function of axial clamping between the fixed shaft 41 and the support column 31 .

[0047] After the support column 31 is removed, the elastic member 24 drives the latch 22 to slide out of the latch slot 23, so as to facilitate the latch 22 to be separated from the support clamping plate 12, thereby achieving the effect of facilitating maintenance.

[0048] During the process of inserting the support column 31 into the support groove 32, the first inclined surface 25 abuts against the second inclined surface 26, and the support column 31 provides a thrust on the latch 22 along the inclination direction of the first inclined surface 25 and the second inclined surface 26, pushing the latch 22 to slide, thereby preventing the latch 22 and the support column 31 from getting stuck.

[0049] Since there are often certain errors in the production and assembly processes, the screw 42 will be offset to a certain extent after being screwed into the support arm 11. Through the setting of the avoidance groove 33, the screw 42 can adapt to the position deviation and offset in the avoidance groove 33 to prevent the screw 42 from being stuck by the support column 31.

[0050] The support column 31 fits the support seat 21 , so that the support column 31 can provide a supporting force to the support seat 21 , thereby ensuring that the support seat 21 can stably support the support splint 12 .

[0051] Embodiment 2:

[0052] refer to Figure 3 A multi-purpose rigid arm clamp comprises a hydraulic drive mechanism 51 and two clamp lock structures in Embodiment 1, wherein the support arm 11 in the clamp lock structure is connected to the hydraulic drive mechanism 51.

[0053] This embodiment has the following advantages:

[0054] The clamp lock structure is arranged in the rigid arm clamp, which achieves the advantage of convenient maintenance of the clamp. By conveniently and quickly replacing different support clamps 12 and anti-skid pads 13, it can adapt to different goods and achieve the effect of improving applicability.

[0055] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
