[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] like Figure 1 as well as Figure 2As shown, the present application provides a clamping device, and an embodiment of the clamping device of the present application includes: a support base 10, a clamping mechanism 20, a first elastic member 30, and a driving handle 40; the support base 10 is provided with a receiving space 11 for placing a member to be clamped and a guide groove 12 extending along a preset direction; the clamping mechanism 20 is movably arranged on the support base 10 along the guide groove 12 and has a clamping position for abutting against the member to be clamped and a releasing position for releasing the member to be clamped, the clamping mechanism 20 includes a clamping portion 21 and a guide rod 22, the guide rod 22 is movably arranged in the guide groove 12, the clamping portion 21 is arranged at the edge of the receiving space 11, and the clamping portion 21 is connected to the first end of the guide rod 22; the first elastic member 30 is provided A resisting force toward the accommodating space 11 is applied between the clamping portion 21 and the support base 10 and to the clamping portion 21, so that the clamping portion 21 can be maintained in the clamping position; the driving handle 40 is connected to the second end of the guide rod 22 and is rotatably arranged relative to the support base 10, and the driving handle 40 has a first position and a second position; wherein, when the driving handle 40 is located at the first position, the first elastic member 30 resists the clamping portion 21 and keeps the clamping mechanism 20 in the clamping position, and when the driving handle 40 is located at the second position, the driving handle 40 overcomes the resisting force of the first elastic member 30 and drives the guide rod 22 to move in the guide groove 12 in a direction away from the accommodating space 11, thereby driving the clamping mechanism 20 to move to the release position.

[0030] By applying the technical solution of this embodiment, the support base 10 provides a support base for the part to be clamped and other parts of the clamping device. The support base 10 is provided with a guide groove 12 extending along a preset direction. The clamping mechanism 20 can abut against the part to be clamped. The clamping mechanism 20 includes a clamping portion 21 and a guide rod 22. The guide rod 22 is movably arranged in the guide groove 12, so that the clamping mechanism 20 can move along the preset direction, and further the clamping mechanism 20 can move between the clamping position and the release position; the first elastic member 30 can apply a push force to the clamping portion 21 toward the accommodating space 11, so that the clamping mechanism 20 can move toward the accommodating space 11 Move and maintain in the clamping position; the driving handle 40 is rotatably arranged and connected to the guide rod 22 and has a first position and a second position; when the driving handle 40 is moved to the first position, the first elastic member 30 can keep the clamping mechanism 20 in the clamping position, so that the clamped part is pushed against by the clamping mechanism 20, and then the clamped part is firmly clamped in the accommodating space 11; when the driving handle 40 is moved to the second position, the driving handle 40 can drive the guide rod 22 to move in a direction away from the accommodating space 11, so that the clamping mechanism 20 releases the clamped part, and then the staff can remove the clamped part from the accommodating space 11. Since the staff only needs to switch the driving handle 40 between the first position and the second position, the clamping mechanism 20 can be switched between the clamping position and the release position, and the clamping mechanism 20 can be stably maintained in the clamping position or the release position, and the staff can use both hands to place or remove the clamped part, thereby improving the staff's efficiency. Therefore, the technical solution of this embodiment can effectively solve the problem of complicated operation of the staff when placing the light board in the related technology.

[0031] It should be noted that the above-mentioned "edge position" refers to the side position or corner position of the accommodating space 11. In the present embodiment, the accommodating space 11 is a rectangular structure and has a plurality of clamping portions 21, wherein some of the clamping portions 21 are located at the corner positions of the accommodating space 11, and some of the clamping portions 21 are located at the side positions of the accommodating space 11 (mentioned later). For the clamping portions 21 arranged at the corner positions of the accommodating space 11, the "preset direction" refers to the direction of the line connecting the corner of the rectangular structure and the center of the rectangular structure; for the clamping portions 21 arranged at the side positions of the accommodating space 11, the "preset direction" refers to the direction perpendicular to the side. In the present embodiment, the first elastic member 30 is a compression spring, and the number is 2. The first elastic member 30 is arranged in the mounting groove 15 (mentioned later), such as Figure 1 As shown, the connecting block 215 (mentioned later) has two fixed wings, one end of the first elastic member 30 is abutted against the side wall of the installation groove 15, and the other end of the first elastic member 30 is abutted against a fixed wing. The guide rod 22 is made of SUS material (stainless steel material).

[0032] like Figure 1 as well as Figure 2 As shown, the clamping device also includes a fixing portion 50 arranged on the support base 10, and the fixing portion 50 is located on the side of the driving handle 40 close to the accommodating space 11. The driving handle 40 includes a top end 41, and the top end 41 has a first mating surface 411 and a second mating surface 412 arranged at an angle. The distance between the first mating surface 411 and the axis of the guide rod 22 is smaller than the distance between the second mating surface 412 and the axis of the guide rod 22. When the driving handle 40 is in the first position, the first mating surface 411 cooperates with the fixing portion 50, and when the driving handle 40 is in the second position, the second mating surface 412 cooperates with the fixing portion 50 to keep the guide rod 22 at a position away from the accommodating space 11.

[0033] Since the distance between the first mating surface 411 and the axis of the guide rod 22 is smaller than the distance between the second mating surface 412 and the axis of the guide rod 22, when the driving handle 40 is switched from the first position to the second position, the distance between the axis of the guide rod 22 connected to the driving handle 40 and the fixing portion 50 will increase, thereby causing the guide rod 22 to move in a direction away from the accommodating space 11 under the restriction of the guide groove 12, thereby driving the clamping mechanism 20 to move in a direction away from the accommodating space 11, thereby causing the clamping mechanism 20 to switch from the clamping position to the release position; at this time, the second mating surface 412 and the fixing portion 50 are abutted against each other, so that the clamping mechanism 20 can be stably maintained in the release position.

[0034] like Figure 1 as well as Figure 2 As shown, the fixing portion 50 includes a fixing base 51 and a second elastic member 52 arranged on the fixing base 51. When the driving handle 40 is located in the first position, the second elastic member 52 is pressed against the first mating surface 411, and the second elastic member 52 applies a force to the first mating surface 411 away from the accommodating space 11. When the driving handle 40 is located in the second position, the second elastic member 52 is pressed against the second mating surface 412, and the second elastic member 52 applies a force to the second mating surface 412 away from the accommodating space 11.

[0035] When the driving handle 40 is located in the second position, the second elastic member 52 abuts against the second mating surface 412, so that the driving handle 40 can be stably maintained in the second position, and the driving handle 40 will not shake or be triggered by mistake; when the driving handle 40 is located in the first position, the second elastic member 52 abuts against the first mating surface 411, so that the driving handle 40 can be stably maintained in the first position, and the driving handle 40 will not shake or be triggered by mistake.

[0036] like Figure 1As shown, the second elastic member 52 includes a fixed section 521 and an elastic arm section 522, the fixed section 521 is connected to the fixed base 51, the first end of the elastic arm section 522 is connected to the fixed section 521, the second end of the elastic arm section 522 is a free end, the elastic arm section 522 is located between the fixed section 521 and the driving handle 40 and can be matched with the first matching surface 411 and the second matching surface 412. The fixed section 521 is used to connect with the fixed base 51, and the elastic arm section 522 is used to provide a counter force to the first matching surface 411 and the second matching surface 412. The second elastic member 52 having the fixed section 521 and the elastic arm section 522 has a simple structure and is easy to process.

[0037] like Figure 1 as well as Figure 2 As shown, the abutting end 41 further includes a transition curved surface 413 disposed between the first mating surface 411 and the second mating surface 412. The transition curved surface 413 makes the driving handle 40 smoother when switching positions, reduces the probability of the driving handle 40 getting stuck, and further reduces the possibility of affecting the clamping and releasing functions of the clamping device due to the jamming of the driving handle 40.

[0038] like Figure 1 as well as Figure 3 As shown, the support base 10 includes a base body 13 and a cover plate 14, the accommodating space 11 is arranged on the base body 13, the base body 13 is provided with a mounting groove 15, the bottom wall of the mounting groove 15 is provided with a through opening 151 penetrating the base body 13 near the accommodating space 11, the clamping portion 21 includes a clamping arm 211, the clamping arm 211 is movably arranged at the through opening 151, the first elastic member 30 is arranged in the mounting groove 15 and is offset from the through opening 151, and the cover plate 14 is covered at the groove opening of the mounting groove 15 and shields the first elastic member 30.

[0039] It should be noted that, in this embodiment, Figure 1 As shown, the mounting groove 15 is an open groove opening downward, that is, the groove bottom wall of the mounting groove 15 is located above the groove opening of the mounting groove 15. The through hole 151 is located at the groove bottom wall of the mounting groove 15 close to the accommodating space 11 and the clamping arm 211 is movable at the through hole 151, so that the clamping arm 211 can abut against the to-be-clamped member, thereby realizing the clamping function of the to-be-clamped member 21. The first elastic member 30 is staggered with the through hole 151 and the cover plate 14 shields the first elastic member 30, so that the first elastic member 30 will not fall out of the mounting groove 15, thereby ensuring the reliability of the clamping and releasing functions of the clamping device.

[0040] In this embodiment, the guide groove 12 is arranged on the cover plate 14, and the driving handle 40 is arranged on the side of the cover plate 14 away from the base body 13. In this way, the driving handle 40, the fixing portion 50 and the clamping mechanism 20 are located on the same side of the support base 10, and are easy to process and install. In other embodiments not shown in the figures, the driving handle and the fixing portion are located on the first side of the support base, the clamping mechanism and the cover plate are located on the second side of the support base, and the guide groove is arranged on the support base.

[0042] like Figure 1 As shown, the clamping device further includes a fastener 60, which is disposed on the base body 13, the cover plate 14 and the fixing portion 50. In this embodiment, the fastener 60 is two fastening screws, which connect the cover plate 14 and the fixing portion 50 to the base body 13.

[0043] like Figure 1 as well as Figure 2 As shown, in this embodiment, the accommodating space 11 is a rectangular structure, and there are multiple clamping parts 21, wherein some clamping parts 21 are arranged at the corners of the rectangular structure, and the clamping parts 21 include a first clamping arm 212 and a second clamping arm 213 arranged at an angle, and the first clamping arm 212 and the second clamping arm 213 extend along two adjacent sides of the rectangular structure respectively.
