Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] In order to solve the technical problem of how to adjust the jaw depth of the clamp, the present utility model provides a clamp with adjustable jaw depth, and the jaw depth can be adjusted by adjusting the relative position of the support platform 300 and the base 100, so as to adapt to materials of different specifications.

[0026] It should be noted that the clamp with adjustable jaw depth of the present utility model is used for but not limited to lifting equipment, etc. For the convenience of description, in the present utility model, only the case where the clamp with adjustable jaw depth is applied to the lifting equipment is taken as an example for description, and the principle of the clamp with adjustable jaw depth applied to other types of equipment is substantially the same as that applied to the lifting equipment, and will not be elaborated here one by one.

[0027] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of a clamp with adjustable jaw depth in an embodiment of the present utility model. The clamp with adjustable jaw depth includes a base 100 and two oppositely arranged clamping jaws 200, and the clamping jaws 200 are rotatably installed on the base 100. The support platform 300 is slidably arranged on the base 100 along the direction towards the material to be clamped. The support platform 300 is located between the two clamping jaws 200, and the support platform 300 can stay at any position on its sliding track.

[0028] In this embodiment, according to the specifications of the material to be clamped, the relative position of the support platform 300 and the base 100 is adjusted. Make the position of the support platform 300 match the specifications of the material. When driving the two clamping jaws 200 to clamp the material, the support platform 300 can be closely attached to the upper surface of the material, so as to play a role in stabilizing the material. By using the above-mentioned clamp with adjustable jaw depth, different specifications of materials can be adapted by adjusting the position of the support platform 300. Furthermore, when clamping materials of different specifications, it can be ensured that the support platform 300 can be closely attached to the upper surface of the material, so as to stabilize the position of the material.

[0029] Any implementation that enables the support platform 300 to slide relative to the base 100 is feasible. In some embodiments, the base 100 is provided with a tongue groove 110, and a part of the support platform 300 is embedded in the tongue groove 110 and can slide relative to the tongue groove 110.

[0030] In this embodiment, under the guiding action of the tongue groove 110, the support platform 300 can slide along the tongue groove 110. The depth at which the support platform 300 is embedded in the tongue groove 110 determines the position of the support platform 300, and thus determines the jaw depth.

[0031] In some embodiments, the clamp with adjustable jaw depth further includes a limiting member 400. The limiting member 400 has a first state that restricts the support platform 300 from sliding relative to the base 100, and a second state that allows the support platform 300 to slide relative to the base 100.

[0032] In this embodiment, when the jaw depth needs to be adjusted, the limiting member 400 can be adjusted to the second state, so that the support platform 300 can slide relative to the base 100. After the position of the support platform 300 is adjusted, the limiting member 400 can be adjusted to the first state to fix the relative position of the support platform 300 and the base 100.

[0033] Based on the above embodiments, in some embodiments, the base 100 is provided with a limiting hole 120 communicating with the tongue groove 110. The support platform 300 is provided with a plurality of mating holes 310 along its length direction. The limiting member 400 includes a first bolt 410. When the limiting member 400 is in the first state, the first bolt 410 passes through the limiting hole 120 and one of the mating holes 310. When the limiting member 400 is in the second state, the first bolt 410 disengages from the limiting hole 120 and the mating hole 310.

[0034] In this embodiment, by passing the first bolt 410 through the limiting hole 120 and any one of the mating holes 310, the movement of the support platform 300 relative to the base 100 can be restricted. By passing the first bolt 410 through different mating holes 310, the support platform 300 can be fixed at different positions. When the first bolt 410 disengages from the limiting hole 120 and the mating hole 310, the restriction of the first bolt 410 is lost, and the support platform 300 can move freely relative to the base 100.

[0035] In some embodiments, there are two mating holes 310. When the support platform 300 is at both ends of its sliding trajectory respectively, the limiting holes 120 are respectively aligned with the two mating holes 310.

[0036] It can be understood that the more the number of mating holes 310, the more difficult it is to align the limiting hole 120 with the mating hole 310. When only two mating holes 310 are provided and the supporting platforms are respectively at both ends of their sliding trajectories, the limiting hole 120 is respectively aligned with the two mating holes 310. This can greatly reduce the difficulty of aligning the limiting hole 120 with the mating hole 310, and thus the position of the supporting platform 300 can be adjusted faster.

[0037] Based on the above embodiments, in some embodiments, a guiding groove 320 is formed along the length direction of the supporting platform 300, a pin hole 130 is formed on the base 100, and the limiting member 400 has a pin shaft 420. The pin shaft 420 is inserted through the guiding groove 320 and the pin hole 130 to limit the sliding range of the supporting platform 300.

[0038] In this embodiment, since the pin shaft 420 is inserted through the guiding groove 320 and the pin hole 130 to limit the sliding range of the supporting platform 300. The sliding range of the pin shaft 420 in the guiding groove 320 is equivalent to the sliding range of the supporting platform 300 relative to the base 100, and the length of the guiding groove 320 determines the length of the sliding trajectory of the supporting platform 300 relative to the base 100.

[0039] In some embodiments, the supporting platform 300 is provided with a plurality of guiding grooves 320 arranged side by side, the base 100 is provided with a plurality of pin holes 130 arranged side by side, and the limiting member 400 has a plurality of pin shafts 420. The plurality of pin shafts 420 are respectively inserted through the guiding grooves 320 and the pin holes 130.

[0040] In this embodiment, by simultaneously providing a plurality of guiding grooves 320, and a plurality of pin holes 130 and pin shafts 420 corresponding to the guiding grooves 320, the stability of the supporting platform 300 during sliding can be improved, and the supporting platform 300 can be prevented from deviating in angle during sliding.

[0041] In some embodiments, the jaw 200 includes a jaw body 210 and a jaw head 220. One end of the jaw body 210 is rotatably mounted on the base 100, and the jaw head 220 is detachably mounted on the inner side of the other end of the jaw body 210.

[0042] In this embodiment, the jaw head 220 can hold the bottom end of the material, so that the material can be clamped more stably.

[0043] As long as the jaw head 220 can be detachably connected to the jaw body 210, the implementation method is feasible. In some embodiments, the jaw body 210 and the jaw head 220 are connected by bolts.

[0044] In some embodiments, the jaw head 220 has a plurality of anti-slip teeth 221.

[0045] In this embodiment, the anti-slip teeth 221 are used to increase the frictional force between the clamping head 220 and the material.

[0046] For a better understanding of the present utility model, the following is a detailed description of the technical solution of the present utility model in conjunction with Figures 1 to 2 :

[0047] First, the first bolt 410 is disengaged from the limiting hole 120 and the mating hole 310. Without the restriction of the first bolt 410, the support platform 300 can move freely relative to the base 100. Then, according to the specifications of the material to be clamped, the relative position of the support platform 300 and the base 100 is adjusted so that the position of the support platform 300 matches the specifications of the material. Subsequently, the first bolt 410 is passed through the limiting hole 120 and the mating hole 310 to fix the relative position of the support platform 300 and the base 100. When the two clamping jaws 200 are driven to clamp the material, the support platform 300 can be closely attached to the upper surface of the material, thus playing a role in stabilizing the material. By using the clamp with adjustable jaw depth, different specifications of materials can be adapted by adjusting the position of the support platform 300. Furthermore, when clamping different specifications of materials, it can be ensured that the support platform 300 can always be closely attached to the upper surface of the material, thereby stabilizing the position of the material.
