Referring to fig. 8 to 12, in some embodiments, a plurality of ribs 314 are protruded on the clamping portion 313 of the clamping plate 31, the plurality of ribs 314 are arranged in parallel at intervals, and the ribs 314 are disposed on a side of the clamping portion 313 of the clamping plate 31 facing the fixing plate 241. Therefore, when the fixing plate 241 is clamped between the top surface of the clamping portion 313 of the clamping plate 31 and the top side inner wall of the locking groove 215, the bead 314 can be clamped between the top surface of the clamping portion 313 of the clamping plate 31 and the bottom surface of the fixing plate 241, enhancing the clamping effect on the fixing plate 241.

Referring to fig. 8 to 12, in some embodiments, the quick release clamping mechanism 3 further includes a first link 33 and a second link 34. The first connecting rod 33 and the second connecting rod 34 are both arranged between the pull rod 32 and the clamping plate 31, the first connecting rod 33 and the second connecting rod 34 are arranged on one side, close to the driving end, of the first rotating shaft 321, and the first connecting rod 33 and the second connecting rod 34 are both arranged on one side, far away from the fixing plate 241, of the first connecting portion 311. One end of the first link 33 is rotatably connected to the pull rod 32, the other end of the first link 33 is rotatably connected to one end of the second link 34, and the other end of the second link 34 is rotatably connected to the clamping plate 31.

Specifically, the first end of the first link 33 has a third rotating shaft 331, one end of the first link 33 is rotatably connected to the pull rod 32 through the third rotating shaft 331, and the third rotating shaft 331 is disposed at a side of the first rotating shaft 321 near the driving end at intervals. The other end of the first link 33 has a fourth rotation shaft 332, and the other end of the first link 33 is rotatably connected to one end of the second link 34 through the fourth rotation shaft 332. The other end of the second link 34 has a fifth rotation shaft 316, and the other end of the second link 34 is rotatably connected to the clamping plate 31 through the fifth rotation shaft 316. Therefore, when the pull rod 32 rotates in the forward direction or the reverse direction, the pull rod 32 can drive the second connecting rod 34 to act through the first connecting rod 33, so that the first connecting rod 33 and the second connecting rod 34 can perform opening and closing actions.

When the pull rod 32 rotates forward, the driving end of the pull rod 32 rotates downward, as shown in fig. 12 to fig. 11, the pull rod 32 drives the first link 33 to move downward, the third shaft 331 and the fourth shaft 332 move downward, and the connecting end of the pull rod 32 drives the clamping plate 31 to move upward, so that the fifth shaft 316 moves upward, and the first link 33 and the second link 34 perform a relative closing motion with the fourth shaft 332 as an axis. Until the fixing plate 241 is clamped and fixed between the top surface of the clamping plate 31 and the top side inner wall of the locking groove 215, the first link 33 and the second link 34 are foldably arranged between the pull rod 32 and the clamping plate 31, as shown in fig. 11.

When the pull rod 32 rotates reversely, the driving end of the pull rod 32 rotates upwards, as shown in fig. 11 to change from the state of fig. 12, the pull rod 32 drives the first link 33 to move upwards, the third rotating shaft 331 moves upwards, and the connecting end of the pull rod 32 drives the clamping plate 31 to move downwards, so that the fifth rotating shaft 316 moves downwards, and the first link 33 and the second link 34 perform a relative opening motion by taking the fourth rotating shaft 332 as an axis. Until the distance between the top surface of the clamping plate 31 and the top side inner wall of the locking groove 215 becomes large, the fixing plate 241 is released, and the fixing plate 241 can be easily withdrawn from the locking groove 215, at this time, the clamping plate 31 is connected to the connection end of the pull rod 32 through the first connection portion 311, and at the same time, is connected to the side of the pull rod 32 near the driving end through the first and second connection links 33 and 34, so that the clamping plate 31 can be arranged in parallel and spaced below the top side inner wall of the locking groove 215, as shown in fig. 12.

Referring to fig. 11, in some embodiments, when the fixing plate 241 is clamped and fixed between the top surface of the clamping plate 31 and the top side inner wall of the locking groove 215, the end portion of the first link 33 connected to the second link 34 can abut against the top surface of the clamping plate 31, i.e., the fourth rotating shaft 332 can abut against the top surface of the clamping plate 31. At this time, the fourth rotating shaft 332 is located at a side of the first connecting portion 311 away from the fixing plate 241, so that the clamping portion 313 located at a side of the first connecting portion 311 close to the fixing plate 241 can be more stably abutted under the bottom surface of the fixing plate 241, and the fixing plate 241 can be more firmly clamped between the clamping portion 313 and the top inner wall of the lock slot 215.

Referring to fig. 8 to 12, in some embodiments, two axial ends of the third rotating shaft 331 protrude from opposite sides of the first connecting rod 33, and two ends of the third rotating shaft 331 are rotatably connected to the pull rod 32.

It should be noted that, in other embodiments, the third rotating shaft 331 may be formed on the pull rod 32, and at this time, one end of the first link 33 is rotatably connected to the third rotating shaft 331.

Referring to fig. 8 to 12, in some embodiments, two axial ends of the fourth rotating shaft 332 protrude from opposite sides of the first connecting rod 33, two opposite sides of an end portion of the second connecting rod 34 connected to the first connecting rod 33 are respectively provided with a second sleeve 341, and the two second sleeves 341 are sleeved on two end portions of the fourth rotating shaft 332 in a one-to-one correspondence.

The fifth rotating shaft 316 is formed at an end of the second connecting portion 315 far from the clamping plate 31, that is, the fifth rotating shaft 316 is formed at a top end of the second connecting portion 315, and an end of the second connecting rod 34 far from the first connecting rod 33 is rotatably connected to the second connecting portion 315 through the fifth rotating shaft 316.

In some embodiments, a third shaft sleeve 342 is disposed at an end of the second connecting rod 34 away from the first connecting rod 33, and the third shaft sleeve 342 is sleeved on the fifth rotating shaft 316, so that the second connecting rod 34 is rotatably connected to the second connecting portion 315 through the third shaft sleeve 342 and the fifth rotating shaft 316.

It should be noted that, in other embodiments, the fifth rotating shaft 316 may be formed at an end portion of the second connecting rod 34 connected to the second connecting portion 315, and accordingly, the third sleeve 342 may be disposed at a top end of the second connecting portion 315.

Referring to fig. 6 to 12, in some embodiments, the upper end cover 211 is provided with a sliding groove 218 extending in an elongated shape, that is, the sliding groove 218 is disposed on the door frame 21. The slide groove 218 is provided on a groove side wall of the fitting groove 216, and the slide groove 218 communicates with the fitting groove 216. The slide groove 218 extends in a direction away from the fixing plate 241, and an extending direction of the slide groove 218 coincides with an extending direction of the fitting groove 216. The first rotating shaft 321 is slidably connected in the sliding groove 218, and the first rotating shaft 321 can rotate relative to the sliding groove 218. Accordingly, the tie rod 32 can slide along the slide groove 218 by the first rotation shaft 321, so that the tie rod 32 relatively moves within the fitting groove 216. Meanwhile, the tie rod 32 can rotate in the fitting groove 216 with the first rotation shaft 321 as an axis.

When the fixing plate 241 is released, as shown in fig. 12, the pull rod 32 can drive the first rotating shaft 321 to move along the sliding groove 218 in a direction away from the fixing plate 241, so that the clamping plate 31 and the first connecting portion 311 move in a direction away from the fixing plate 241, so that a sufficient distance is kept between the first connecting portion 311 and the fixing plate 241, and the first connecting portion 311 is prevented from obstructing the fixing plate 241 from withdrawing from the locking groove 215.

Referring to fig. 11 and 12, when the fixing plate 241 needs to be clamped, the first rotating shaft 321 can be driven by the pull rod 32 to move along the sliding groove 218 towards the direction approaching to the fixing plate 241, and then the pull rod 32 is rotated forward, so that the pull rod 32 can be completely accommodated in the assembly groove 216, and at this time, the fixing plate 241 can be ensured to be clamped between the clamping plate 31 and the top side inner wall of the locking groove 215.

In some embodiments, two slide grooves 218 are provided, with two slide grooves 218 being provided on opposite sides of the fitting groove 216. Both ends of the first rotating shaft 321 are slidably connected to a sliding groove 218 respectively.
