[0028] At present, the arms in the gripper are mostly connected and power-transmitted through rotatable rods, and the arms are mostly exposed to the outside. However, when the gripper is gripping an object, the arms of the gripper inevitably need to come into contact with the object. When a strong collision occurs between the gripper and the object, the arms of the gripper are easily damaged.

[0029] To address the problem that a clamping jaw is easily damaged, the present invention provides a clamping jaw, comprising: a housing, a side portion of the housing being provided with a plurality of first slots, each of the first slots being provided with a stop block at both ends, and a top portion of the housing being provided with a telescopic hole; a telescopic column being provided in the telescopic hole and configured to reciprocate linearly in the telescopic hole, and a plurality of second slots being provided at one end of the telescopic column located within the housing; a plurality of connecting members, each of the connecting members being fixed in a corresponding second slot and provided with a first hole; and a plurality of friction members, each of the friction members being provided in a corresponding first slot and rotatably connected to the housing, an end of the friction member proximal to the connecting member being provided with a second hole, the first hole and the second hole being connected by a first support rod, and an end of the friction member remote from the connecting member being in frictional contact with an object; wherein the first hole is elliptical, the minor axis length of the first hole is equal to the diameter of the cross section of the first support rod, and the distance between the upper portion of the first hole and the central axis of the housing is smaller than the distance between the lower portion of the first hole and the central axis of the housing; according to the solution provided in the embodiment of the present invention, the friction members and the connecting members can be effectively protected.

[0030] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings.

[0031] Reference Figures 1 to 6 , an embodiment of the utility model provides a clamping claw, comprising:

[0032] The housing 100 has a plurality of first slots 110 on its side, with stoppers 120 at both ends of each first slot 110, and a telescopic hole 130 on its upper portion.

[0033] The telescopic column 200 is disposed on the telescopic hole 130. The telescopic column 200 is used for reciprocating linear motion in the telescopic hole 130. A plurality of second slots 210 are provided at one end of the telescopic column 200 located within the housing 100.

[0034] A plurality of connecting members 300, each connecting member 300 is fixed on a corresponding second slot 210, and a first hole 310 is provided on the connecting member 300;

[0035] Multiple friction members 400, each of which is disposed on a corresponding first slot 110. The friction member 400 is rotatably connected to the housing 100. A second hole 410 is disposed on an end of the friction member 400 that is close to the connecting member 300. The first hole 310 and the second hole 410 are connected by a first support rod 610. An end of the friction member 400 that is away from the connecting member 300 is in frictional contact with an object. The stop block 120 is used to protect the friction member 400 in the corresponding first slot 110.

[0036] Among them, the first hole 310 is elliptical, the short axis length of the first hole 310 is equal to the diameter of the cross section of the first support rod 610, and the distance between the upper part of the first hole 310 and the central axis of the shell 100 is smaller than the distance between the lower part of the first hole 310 and the central axis of the shell 100.

[0037] It can be understood that when the telescopic column 200 moves downward, the connecting member 300 moves downward accordingly, and the first support rod 610 slides upward relative to the first hole 310. After the first support rod 610 contacts the upper part of the first hole 310, the connecting member 300 pushes the first support rod 610 to move downward, and the first support rod 610 drives the upper part of the friction member 400 to contract inward, and the lower part of the friction member 400 to expand outward, thereby loosening the object; when the telescopic column 200 moves upward, the connecting member 300 moves upward, and the first support rod 610 moves downward relative to the first hole 310, so that the first support rod 610 drives the upper part of the friction member 400 to move outward, and the lower part of the friction member 400 moves toward the central axis of the housing 100, and the lower part of each friction member 400 clamps the object, thereby fixing the object. ; Therefore, the clamp proposed by the present invention only relies on the linear reciprocating motion of the telescopic column 200. The user only needs to control the movement of the telescopic column 200, and can achieve clamping and releasing of objects in three-dimensional space through operations in a single dimension, which simplifies the operation process; by arranging shift blocks 120 at both ends of each first slot 110, the friction member 400 is arranged between the corresponding two shift blocks 120, so that the shift blocks 120 can protect the friction member 400 and prevent other components from colliding with the clamp and causing damage to the friction member 400; and the clamp proposed by the present invention realizes efficient use of space by integrating the telescopic column 200, the connecting member 300 and the friction member 400 in a shell 100, so that the clamp device is small in size and light in weight, which is easy to install and carry.

[0038] In addition, refer to Figure 1 and Figure 3 In one embodiment of the present invention, the clamp further includes a fixing column 500 , which is disposed on the telescopic column 200 and is fixedly connected to the housing 100 .

[0039] In a specific embodiment, a fixing component is provided on the fixing column 500, and the fixing component is used to fix the clamping claw.

[0040] In addition, refer to Figure 3 and Figure 6 As shown, in one embodiment of the present invention, the interior and lower portion of the fixed column 500 are hollowed out, and the fixed column 500 is sleeved on the telescopic column 200 .

[0041] It can be understood that the interior and lower portion of the fixed column 500 are hollowed out, the telescopic column 200 is located inside the fixed column 500, and the length of the fixed column 500 is fixed. The linear movement range of the telescopic column 200 is limited by the length of the fixed column 500, thereby preventing the telescopic column 200 from excessively moving outward and causing damage to the connection between the friction member 400 and the connecting member 300; and, the fixed column 500 and the housing 100 simultaneously protect the telescopic column 200 in the inner cavity, thereby preventing damage to the telescopic column 200 caused by collision with other components.

[0042] In addition, refer to Figure 6 As shown, in one embodiment of the present invention, a latching key 510 is provided at the lower portion of the fixing column 500 , and a latching groove 131 is provided on the first slot 110 , and the latching key 510 is engaged with the latching groove 131 .

[0043] It can be understood that by providing a locking key 510 at the lower part of the fixing column 500 and providing a locking groove 131 on the first slot 110, when the fixing column 500 is installed on the first slot 110, the locking key 510 and the locking groove 131 are engaged with each other, thereby forming a tight fitting relationship, which can avoid relative movement between the fixing column 500 and the shell 100 and improve the stability of the clamp.

[0044] In addition, refer to Figure 6 As shown, in one embodiment of the present invention, a third hole 220 is provided on the upper portion of the telescopic column 200 , a fourth hole 520 is provided on the upper portion of the fixed column 500 , and the third hole 220 and the fourth hole 520 are connected by a second support rod 620 .

[0045] In a specific embodiment, a plurality of positioning slots are provided on the second support rod 620 , and the third hole 220 and the fourth hole 520 are respectively engaged with the positioning slots, thereby fixing the fixed column 500 and the telescopic column 200 at one position of the second support rod 620 .

[0046] In addition, refer to Figure 6 As shown, in one embodiment of the present invention, the diameter of the third hole 220 is equal to the diameter of the cross section of the second support rod 620, the length of the fourth hole 520 in the direction parallel to the fixing column 500 is greater than the diameter of the cross section of the second support rod 620, and the length of the fourth hole 520 in the direction perpendicular to the fixing column 500 is equal to the diameter of the cross section of the second support rod 620.

[0047] Specifically, the third hole 220 is fitted with the second support rod 620. The user pulls the second support rod 620 upward relative to the housing 100, thereby driving the telescopic column 200 to move upward. The user pulls the second support rod 620 downward relative to the housing 100, thereby driving the telescopic column 200 to move downward. The movable distance of the second support rod 620 and the telescopic column 200 is equal to the length of the fourth hole 520 in the direction parallel to the fixed column 500.

[0048] In addition, refer to Figure 6 As shown, in one embodiment of the present invention, limiting blocks 621 are provided at both ends of the second support rod 620 , and the diameter of the cross section of the limiting blocks 621 is larger than the diameter of the cross section of the second support rod 620 .

[0049] It is understandable that after the clamp grasps and fixes the object, by fixing the second support rod 620, the user can move the clamp along the second support rod 620, thereby being able to flexibly adjust the position of the clamp and the object. When adjusting the position of the clamp on the second support rod 620, the limit block 621 limits the position of the fixed column 500 and the telescopic column 200, thereby preventing the clamp from falling off the second support rod 620 and ensuring the safety of the object.

[0050] In a specific embodiment, the user may also first fix the second support rod 620, and the user lifts the outer shell 100 upwards, thereby spreading the lower part of the friction member 400 outwards, and the user places the object in the middle of the friction member 400, and then drops the outer shell 100 downwards, and the lower part of the friction member 400 moves toward the middle and contacts the object, thereby fixing the object.

[0051] In addition, refer to Figure 2 As shown, in one embodiment of the present invention, a friction coating 401 is provided on one side of the friction member 400 close to the central axis of the housing 100 .

[0052] It can be understood that by providing a friction coating 401 on the side of the friction part 400 close to the object, when the friction part 400 is in contact with the object, the friction coating 401 can increase the friction between the friction part 400 and the object, thereby improving stability and ensuring reliability and safety during the process of clamping and releasing the object by the clamping jaws.

[0053] In addition, refer to Figure 5 As shown, in one embodiment of the present invention, the clamp further includes a third support rod 630, a fifth hole 420 is provided through each friction member 400, a sixth hole 111 is provided on both sides of each shift block 120, the third support rod 630 passes through the fifth hole 420, and both ends of the third support rod 630 respectively abut against the corresponding two sixth holes 111.

[0054] It can be understood that the third support rod 630 fixes the friction member 400 on the first slot 110. When the telescopic column 200 performs reciprocating linear motion, the telescopic column 200 rotates back and forth with the third support rod 630 as the center. When the upper part of the telescopic column 200 moves upward, the lower part of the telescopic column 200 moves toward the central axis of the shell 100, thereby fitting with the object. When the upper part of the telescopic column 200 moves downward, the lower part of the telescopic column 200 moves out of the shell 100, thereby releasing the object.

[0055] In addition, in one embodiment of the present invention, the present invention further provides a power distribution cabinet, comprising:

[0056] Cabinet, in which power distribution components are placed;

[0057] Like the clamp in the above embodiment, the clamp is installed in the cabinet and is used to grab and fix the power distribution component.

[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
