[0034] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0035] As disclosed in the background technology section, existing seat belt clamping devices are inconvenient and laborious to operate when in use. The embodiments of the present application provide a seat belt clamping device and a seat, which are at least used to solve this technical problem.

[0036] Please refer to Figure 1 , Figure 2 The seat belt clamping device 10 provided in the embodiment of the present application includes a fixing seat 100, a main body 200, a handle 300, a locking assembly 400 and a first reset member 500. The main body 200 is rotatably arranged on the fixing seat 100 to form a gap for installing the seat belt between the main body 200 and the fixing seat 100; the handle 300 and the locking assembly 400 are both movably arranged on the main body 200, and the handle 300 is used to drive the locking assembly 400 to move until The locking assembly 400 fixes the handle 300 and the main body 200 relatively; the locking assembly 400 is used to release the fixation of the handle 300 and the main body 200 when the main body 200 rotates toward the fixing seat 100, and the first reset member 500 is arranged between the main body 200 and the handle 300, and is used to push the handle 300 to move after the locking assembly 400 releases the fixation of the handle 300 and the main body 200, so as to reset the locking assembly 400 and lock it to the fixing seat 100.

[0037] The main body 200 is rotatably disposed on the fixing seat 100 via a rotating pin 240. When the main body 200 is rotated relative to the fixing seat 100, a gap for installing the safety belt can be formed between the main body 200 and the fixing seat 100. After the safety belt is installed in the gap, the main body 200 is rotated in the opposite direction until the main body 200 and the fixing seat 100 cooperate to clamp the safety belt.

[0038] The moving direction of the handle 300 is perpendicular to the moving direction of the locking assembly 400. When a person pulls the handle 300 toward the outside of the main body 200, the handle 300 can drive the locking assembly 400 to move until the locking assembly 400 fixes the handle 300 and the main body 200 relatively, and at the same time, the locking assembly 400 can be unlocked from the fixing seat 100; when the main body 200 rotates toward the fixing seat 100, the locking assembly 400 releases the fixation of the handle 300 and the main body 200. At this time, the first reset member 500 pushes the handle 300 to move toward the inside of the main body 200, the handle 300 drives the locking assembly 400 to reset, and the locking assembly 400 is re-locked to the fixing seat 100.

[0039] The first restoring member 500 may be a spring connected between the main body 200 and the handle 300 .

[0040] When the seat belt clamping device 10 is in use, the handle 300 is pulled toward the outside of the main body 200, and the handle 300 drives the locking assembly 400 to move until the locking assembly 400 and the fixing seat 100 are unlocked, and the locking assembly 400 fixes the handle 300 and the main body 200 relatively; then the main body 200 is rotated relative to the fixing seat 100, a gap for installing the seat belt is formed between the main body 200 and the fixing seat 100, and then the seat belt is installed in the gap; finally, the main body 200 is rotated toward the fixing seat 100, the locking assembly 400 releases the fixation of the handle 300 and the main body 200, and the first reset member 500 pushes the handle 300 to move toward the inside of the main body 200, so that the locking assembly 400 is reset and locked to the fixing seat 100, at which time the main body 200 and the fixing seat 100 cooperate to clamp the seat belt, and the seat belt clamping device 10 is easy to operate and relatively labor-saving.

[0041] In this embodiment, the locking assembly 400 includes a locking member 410 and a positioning member 420, and the locking member 410 and the positioning member 420 are both movably arranged on the main body 200. The fixing seat 100 is provided with a locking portion 110 for cooperating with the locking member 410. The positioning member 420 is used to position the locking member 410 after the locking member 410 is released from the cooperation with the locking portion 110, and the positioning member 420 is used to release the positioning of the locking member 410 when the main body 200 is rotated toward the fixing seat 100. The first reset member 500 is used to push the handle 300 to move after the positioning member 420 releases the positioning of the locking member 410, so as to reset the locking member 410 and lock it to the fixing seat 100.

[0042] The moving directions of the handle 300, the locking member 410, and the positioning member 420 are perpendicular to each other. When the locking member 410 cooperates with the locking portion 110, the main body and the fixing seat 100 are relatively fixed; when the locking member 410 is released from the cooperation with the locking portion 110 and the positioning member 420 positions the locking member 410, the locking member 410 and the main body are relatively fixed; when the main body 200 rotates toward the fixing seat 100, the positioning member 420 releases the positioning of the locking member 410, and the first reset member 500 can push the handle 300 to move toward the inside of the main body 200, the handle 300 drives the locking member 410 to reset, and the locking member 410 cooperates with the locking portion 110 again.

[0043] Please combine Figure 3-Figure 5In this embodiment, the locking member 410 is a locking pin, the locking portion 110 is a locking hole, the main body 200 is provided with a first sliding groove 210 for the locking pin to slide, the locking pin is provided with a first guiding portion 411, and the handle 300 is provided with a first guiding hole 310 cooperating with the guiding portion. When the handle 300 moves, the first guiding portion 411 moves in the first guiding hole 310, thereby driving the locking pin to slide along the first sliding groove 210, and the extension direction of the first guiding hole 310 is inclined relative to the moving direction of the handle 300.

[0044] The length direction of the locking pin is consistent with the extension direction of the first sliding groove 210 . The first guiding portion 411 may be a column. The first guiding portion 411 is perpendicular to the locking pin, and the first guiding portion 411 passes through the first guiding hole 310 .

[0045] When the handle 300 is pulled toward the outside of the main body, the first guide part 411 moves in the first guide hole 310, thereby driving the locking pin to slide along the first slide groove 210 toward the inside of the main body; when the first reset member 500 pushes the handle 300 to move toward the inside of the main body 200, the first guide part 411 moves in the first guide hole 310, thereby driving the locking pin to slide along the first slide groove 210 toward the outside of the main body.

[0046] In an optional embodiment, the number of the locking pin, the locking hole, the first slide groove 210, the first guide portion 411 and the first guide hole 310 is two, the two locking holes are relatively opened on the side wall of the fixing seat 100, the two locking pins are respectively slidably set in the two first slide grooves 210, and the two first guide portions 411 are respectively penetrated by the two first guide holes 310.

[0047] When the handle 300 moves, the two first guide portions 411 move in the two first guide holes 310 respectively, thereby driving the two locking pins to slide toward or away from each other along the two first sliding grooves 210 respectively.

[0048] In this embodiment, a positioning portion 421 is provided on the positioning member 420, and a positioning hole 412 is opened on the locking pin. The positioning portion 421 is used to cooperate with the positioning hole 412 when the locking pin slides toward the inside of the main body 200, and the positioning member 420 is used to abut the fixing seat 100 and move relative to the fixing seat 100 when the main body 200 rotates toward the fixing seat 100 until the positioning portion 421 is released from the positioning hole 412.

[0049] The opening direction of the positioning hole 412 is perpendicular to the locking pin. When the positioning portion 421 is matched with the positioning hole 412, the locking pin is relatively fixed to the main body. The positioning member 420 has an extension end 422, which passes through the main body 200 and extends to the bottom of the main body 200. When the main body 200 rotates toward the fixing seat 100, the extension end 422 abuts against the fixing seat 100, so that the positioning portion 421 and the positioning hole 412 are released from the match.

[0050] When the number of locking pins, locking holes, first slide grooves 210, first guide portions 411 and first guide holes 310 are all two, two positioning portions 421 are provided on the positioning member 420, and positioning holes 412 are provided on the two locking pins. The two positioning portions 421 are respectively used to cooperate with the positioning holes 412 on the two locking pins.

[0051] In this embodiment, the positioning portion 421 is provided with an inclined surface 4211 , which is arranged toward the locking hole. When the locking pin slides toward the inside of the main body 200 , it abuts against the inclined surface 4211 to move the positioning member 420 .

[0052] When the handle 300 is pulled toward the outside of the main body, the locking pin slides along the first slide groove 210 toward the inside of the main body and abuts the inclined surface 4211, so that the positioning member 420 moves toward the top of the main body 200, and when the positioning portion 421 is aligned with the positioning hole 412, the positioning portion 421 cooperates with the positioning hole 412.

[0053] In this embodiment, a second restoring member 600 is disposed between the main member 200 and the positioning member 420 , and the second restoring member 600 is used to drive the positioning member 420 to move relative to the main member 200 until the positioning portion 421 is matched with the positioning hole 412 .

[0054] The extending end 422 of the positioning member 420 is provided with a screw 423 , and the second reset member 600 may be a spring, which is sleeved on the positioning member 420 , and the two ends of the spring respectively abut against the screw 423 and the main member 200 .

[0055] When the main body 200 rotates toward the fixing seat 100, the screw 423 abuts against the fixing seat 100, and the spring is compressed until the positioning portion 421 is released from the positioning hole 412. When the positioning portion 421 is aligned with the positioning hole 412, the spring drives the positioning member 420 to reset, thereby making the positioning portion 421 fit with the positioning hole 412.

[0056] In this embodiment, a second slide groove 220 for the positioning member 420 to slide is provided on the main body 200 , and the bottom end of the positioning member 420 extends out of the main body 200 through the second slide groove 220 to abut against the fixing seat 100 .

[0057] The extension direction of the second slide groove 220 is perpendicular to the extension direction of the first slide groove 210 , and the bottom end of the positioning member 420 , ie, the extension end 422 , extends out of the main member 200 from the second slide groove 220 .

[0058] In this embodiment, the handle 300 is provided with a hole 320 for the positioning member 420 to extend out.

[0059] When the positioning member 420 slides along the second sliding groove 220 , the hole 320 can allow the positioning member 420 to extend out to play a role of making way.

[0060] In this embodiment, a second guide portion 230 is provided on the main body 200, and a second guide hole 330 cooperating with the second guide portion 230 is opened on the handle 300. The extension direction of the second guide hole 330 is consistent with the moving direction of the handle 300. When the handle 300 moves, the second guide portion 230 moves in the second guide hole 330.

[0061] The second guide portion 230 may be a column, the second guide portion 230 is perpendicular to the locking pin, and a second guide hole 330 is formed through the second guide portion 230 .

[0062] When the handle 300 moves, the second guide portion 230 moves in the second guide hole 330 , so that the handle 300 always moves along the extending direction of the second guide hole 330 .

[0063] In an optional embodiment, the number of the second guide portions 230 and the number of the second guide holes 330 are both two, and the two second guide portions 230 are respectively provided with two second guide holes 330 .
