When the car frame body 11 falls accidentally, the car frame body 11 moves downward quickly, so that the air flow rate entering the fixed box 502 through the conical cover 801 becomes faster, and the arc plate 704 is pushed upward by the pushing mechanism. At the same time, the second spring 602 is compressed. When the arc plate 704 moves upward, it pushes the square rod 601 and the third conductive block 507 to move upward synchronously, so that the third conductive block 507 contacts the first conductive block 505 and the second conductive block 506. At this time, the circuit of the control motor 305 is connected.

[0032] Preferably, the first reset mechanism includes a square rod 601 inserted into the upper side wall of the L-shaped plate 503, and the upper end of the square rod 601 is fixed to the bottom of the third conductive block 507. The side wall of the square rod 601 is sleeved with a second spring 602, which guides and resets the movement of the third conductive block 507.

[0033] Preferably, the pushing mechanism includes a fixed ring 702 rotatably connected to the side wall of the fixed box 502 through a rotating shaft 701, and the side wall of the fixed ring 702 is connected to a metal ball 703 through a plurality of second reset mechanisms, the lower end of the square rod 601 is fixedly connected to an arc plate 704, and the metal ball 703 slides on the lower side wall of the arc plate 704, the rotation of the rotating shaft 701 is driven by the driving assembly, and the car frame body 11 moves downward rapidly, so that the air flow rate entering the fixed box 502 through the conical cover 801 becomes faster, and the rotation of the fixed ring 702 and the metal ball 703 is driven by the driving assembly, so that the metal ball 703 moves away from the rotating shaft 701 under the action of centrifugal force, and at the same time, the third spring 1004 is compressed. At this time, the metal ball 703 is against the lower side wall of the arc plate 704, thereby pushing the arc plate 704 to move upward.

[0034] Preferably, the driving assembly includes a conical cover 801 fixedly connected to the bottom of the fixed box 502, and the top of the fixed box 502 is fixedly connected to an exhaust pipe 802, one end of the rotating shaft 701 passes through the fixed box 502 and is fixedly sleeved with a rotating fan 803, so that the rotating fan 803 and the rotating shaft 701 rotate rapidly, and the rotation of the rotating shaft 701 drives the rotation of the fixed ring 702 and the metal ball 703.

[0035] Preferably, the second reset mechanism includes a first sleeve 1001 fixedly connected to a plurality of arrays arranged on the side wall of the fixed ring 702, and a first sliding disk 1002 is slidably connected inside the first sleeve 1001, the end of the first sliding disk 1002 is fixedly connected to a first rod 1003, and the other end of the first rod 1003 is fixed to the side wall of the metal ball 703, and the side wall of the first rod 1003 is sleeved with a third spring 1004, which guides and resets the movement of the metal ball 703.

[0036] Preferably, the blowing mechanism includes a plurality of blowing pipes 901 fixedly inserted in an array on the side wall of the sliding groove 302, and the other end of the blowing pipe 901 is fixedly connected to the working pipe 902, and the upper end of the air outlet pipe 802 is fixedly connected to the connecting pipe 903, and the two ends of the connecting pipe 903 are fixed to the side wall of the working pipe 902. When the car frame body 11 moves downward, the air enters the fixed box 502 through the conical cover 801 and enters the connecting pipe 903 after passing through the air outlet pipe 802. Then, after passing through the working pipe 902, it is sprayed on the surface of the double-headed threaded rod 303 through the blowing pipe 901, so that during the movement of the car frame body 11, the dust and other impurities on the surface of the double-headed threaded rod 303 can be automatically blown clean, thereby making the movement of the sliding block 304 smoother and avoiding its jamming.

[0037] Preferably, the buffer mechanism includes two symmetrically arranged fixed plates 201 fixedly connected to the bottom of the car frame body 11, and the lower side wall of the fixed plate 201 is fixedly connected to the second rod 202, the side wall of the second rod 202 is sleeved with a second sleeve 204, and the second sliding plate 203 is slidably connected in the second sleeve 204, the upper side wall of the second sliding plate 203 is provided with a plurality of through holes 206 arranged in an array, and the upper side wall of the second sliding plate 203 is fixed to the lower end of the second rod 202, and the lower end of the second sleeve 204 is fixedly connected to The support plate 205 is provided, and a third reset mechanism is provided between the second sleeve 204 and the fixed plate 201. When the car frame body 11 descends, when the support plate 205 abuts against the bottom of the elevator shaft 1, the second sliding plate 203 moves downward in the second sleeve 204. At the same time, the damping oil flows along the through hole 206, which can play a good damping and buffering effect, and has a good buffering effect on the car frame body 11, effectively avoiding the falling off of the car frame body 11, and at the same time, ensuring the use effect and life of the car frame body 11.

[0038] Preferably, the third reset mechanism includes a fourth spring 207 sleeved on the side wall of the second sleeve rod 202 , which plays a role in resetting the movement of the second sleeve rod 202 and the second sliding plate 203 .

[0039] Working principle: When in use, when the car frame body 11 moves downward, air enters the fixed box 502 through the conical cover 801 and enters the connecting pipe 903 after passing through the air outlet pipe 802. Then, it passes through the working pipe 902 and is sprayed onto the surface of the double-threaded rod 303 through the air blowing pipe 901. In this way, dust and other impurities on the surface of the double-threaded rod 303 can be automatically blown away during the movement of the car frame body 11, thereby making the movement of the sliding block 304 smoother and avoiding its jamming.

[0040] When the car frame body 11 falls accidentally, the car frame body 11 moves downward rapidly, causing the air flow rate entering the fixed box 502 through the conical cover 801 to increase, thereby causing the rotary fan 803 and the rotating shaft 701 to rotate rapidly. The rotation of the rotating shaft 701 drives the rotation of the fixed ring 702 and the metal ball 703, causing the metal ball 703 to move away from the rotating shaft 701 under the action of centrifugal force. At the same time, the third spring 1004 is compressed. At this time, the metal ball 703 abuts against the lower side wall of the curved plate 704, thereby pushing the curved plate 704 to move upward. At the same time, the second spring 602 is compressed. When the curved plate 704 moves upward, it pushes the square rod 601 and the third conductive block 507 to move upward synchronously, thereby causing the third conductive block 507 to contact the first conductive block 505 and the second conductive block 506. At this time, the circuit of the control motor 305 is connected, causing the motor 305 to rotate.

[0041] The rotation of the motor 305 drives the rotation of the double-threaded rod 303, thereby driving the two sliding blocks 304 to move away from each other synchronously. The movement of the sliding block 304 drives the movement of the square tube 402 and the inclined surface 405. When the inclined surface 405 abuts against the side wall of the fixed block 401, the first spring 403 is compressed. When the moving rod 404 is inserted between the two fixed blocks 401, the car frame body 11 is limited, thereby preventing the car frame body 11 from falling accidentally, protecting the safety of passengers in the elevator, and being safer and more reliable. Moreover, when the car frame body 11 stops, the metal ball 703 moves and resets under the action of the third spring 1004. At the same time, the third conductive block 507 moves and resets downward under the action of the second spring 602, so that the third conductive block 507 is disconnected from the first conductive block 505 and the second conductive block 506, thereby automatically disconnecting the circuit controlling the motor 305, which is more convenient to use.

[0042] Moreover, when the car frame body 11 descends, when the support plate 205 abuts against the bottom of the elevator shaft 1, the second sliding plate 203 moves downward in the second sleeve 204, and the fourth spring 207 is compressed. At the same time, the damping oil flows along the through hole 206, which can play a good damping and buffering effect, and has a good buffering effect on the car frame body 11, effectively avoiding the falling off of the car frame body 11, and at the same time, ensuring the use effect and life of the car frame body 11.
