Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical parking lot, in particular to a mechanical parking lot vehicle loading plate inclination calibration mechanism. BACKGROUND

[0002] It is known that mechanical parking lots are divided into lifting and horizontal moving type, vertical lifting type, plane moving type, vertical circulating lifting type, simple lifting type, multi-layer circulating type, and mechanical type of roadway stacking type according to their structures. Mechanical parking lots have the characteristics of convenient storage and retrieval, economical operation, convenient maintenance, and small land occupation, and are a solution to the problem of more vehicles and less parking area.

[0003] Among them, the vertical circulating lifting type mechanical parking lot can be built by occupying two parking spaces on the ground floor, and the equipment is as high as ten or even dozens of layers. When parking, the driver can park the vehicle on the vehicle loading plate above the ground floor. After the driver leaves the vehicle, the mechanical transmission device operates to lift the vehicle loading plate where the vehicle is parked upward, and the next empty vehicle loading plate is lowered to the ground floor. When taking the car, the mechanical transmission device lowers the vehicle loading plate where the specified vehicle is parked to the ground floor, and the driver drives away with the vehicle. The mechanical transmission device is realized by a set of circulating lifting mechanism, such as a chain transmission mechanism.

[0004] For example, a suspension type vertical circulating parking lot with lifting mechanism, with publication number CN113062644A and publication date July 2, 2021, includes an upper support frame and a lower support frame fixed above the ground, and the bottom of the upper support frame is fixed with a main track, and the top of the lower support frame is fixed with a stable track. A plurality of self-propelled units are provided between the main track and the stable track. The main track includes a running track in the middle and a plurality of parking tracks symmetrically arranged on both sides of the running track. The end of the running track is provided with at least one lifting mechanism for driving the self-propelled unit to make vertical lifting motion. The suspension type vertical circulating parking lot with lifting mechanism provided in the application only occupies the ground area with the column and the lifting mechanism, and has small land occupation. When building, the column and the lifting mechanism can be arranged at a position that does not affect or has little impact on the road function, so as to reasonably utilize the urban space, provide a large number of parking spaces, realize high-density parking, and solve the problem of lack of parking lots in the city.

[0005] The prior art has the problem that the vehicle carrying mechanism of the vertical circulation lifting parking lot is prone to swing during the lifting circulation operation, and the vehicle carrying mechanism is inclined, the connection between the vehicle carrying mechanism and the lifting mechanism before the vehicle is parked on the vehicle carrying mechanism is greatly increased by gravity, and the wear of the connection is aggravated when swinging, and the above shows that this is obviously not conducive to ensuring parking safety, so a device for calibrating and limiting the vehicle carrying mechanism is needed to prevent the vehicle carrying mechanism from swinging and tilting during operation. SUMMARY

[0006] The purpose of the present application is to provide a mechanical parking lot vehicle carrying plate inclination calibration mechanism to solve the technical problems in the related art.

DETAILED DESCRIPTION

[0033] In order for those skilled in the art to better understand the technical solutions of the present application, the following will combine the accompanying drawings to make a detailed description of the present application. Figure 1 to the accompanying drawings Figure 11 Further detailed description of the present application.

[0034] In the description of the present application, it should be understood that the terms "center", "length", "width", "degree", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0035] The embodiment of the present application provides a mechanical parking lot vehicle carrying plate inclination calibration mechanism, which comprises a circulating lifting mechanism 1, a plurality of vehicle carrying mechanisms 2 are arranged in sequence along a motion track on the circulating lifting mechanism 1, a first track 3 is arranged along the motion track, a plurality of first blocks 30 are slidably arranged on the first track 3, the plurality of first blocks 30 correspond to the plurality of vehicle carrying mechanisms 2 one by one and are fixedly connected, a second track 4 parallel to or coinciding with the first track 3 is arranged, a plurality of second blocks 40 are slidably arranged on the second track 4, a rod body 5 is mounted on each vehicle carrying mechanism 2, and each rod body 5 is fixedly connected with a second block 40.

[0036] Specifically, the circulating lifting mechanism 1 preferably uses a driving source to drive a chain transmission mechanism, wherein the chain transmission mechanism is vertically arranged, and two chains are arranged, and the space between the two chains is used for the running of the vehicle carrying mechanism 2, that is, the chain is divided into a vertical ascending section and a vertical descending section during running, and two circular arc sections connecting the horizontal opposite ends of the vertical ascending section and the vertical descending section, the vehicle carrying mechanism 2 is a mechanism for containing vehicles, and a plurality of vehicle carrying mechanisms 2 are arranged in sequence on the entire motion track of the chain transmission mechanism such as a chain wheel, when parking or taking a vehicle, the empty vehicle carrying mechanism 2 or the vehicle carrying mechanism 2 containing the corresponding vehicle is moved to the lowest position by the driving source driving the chain transmission mechanism, that is, the vehicle carrying mechanism 2 is moved to the ground layer, so as to park or drive away the vehicle. Since the chain in the chain transmission mechanism has a certain tightness requirement during use, and the weight of the vehicle carrying mechanism 2 after parking the vehicle is basically above one ton, the part of the vertical section of the chain close to the ground will be relaxed by the gravity of the vehicle carrying mechanism 2, and the part of the vertical section of the chain away from the ground will be relaxed, which will cause the chain to horizontally swing, therefore, in the embodiment, the first track 3 is arranged, and the vehicle carrying mechanism 2 is connected with the first block 30 corresponding to the first track 3, so as to limit the chain in the horizontal direction, that is, the first block 30 is connected with the chain, the first block 30 cannot swing left and right, and the chain also cannot swing left and right, so as to avoid the above situation.

[0037] The track of the first track 3 coincides with the movement track of the chain, and the vehicle needs to be kept stable after the whole vehicle parking mechanism 2 parks the vehicle. Therefore, the connection part of the vehicle parking mechanism 2 and the first block 30 needs to be deflected when the vehicle parking mechanism 2 passes through the circular arc segment, so as to realize the deflection. Therefore, a new problem is brought, that is, the vehicle parking mechanism 2 is prone to swing in the lifting cycle operation process. Therefore, the vehicle parking mechanism 2 is prone to tilt. After the vehicle is parked on the vehicle parking mechanism 2, the connecting part between the vehicle parking mechanism 2 and the lifting mechanism is greatly increased under the gravity. Therefore, when the vehicle swings, the wear of the connecting part is increased. This is obviously not conducive to ensuring the safety of parking. In the embodiment, the second track 4 is additionally arranged on the basis. The second track 4 is also provided with the second block 40 connected with the vehicle parking mechanism 2. The first track 3 is parallel to the second track 4. That is, the vertical segment of the first track 3 is parallel to the vertical segment of the second track 4. The circular arc segment of the first track 3 is parallel to the circular arc segment of the second track 4. Therefore, the vehicle parking mechanism 2 is equivalent to two restrictions in the operation process. Therefore, when the vehicle parking mechanism 2 passes through the circular arc segment, the relative rotation between the vehicle parking mechanism 2 and the first block 30 can still occur. Due to the limitation of the second track 4, the second block 40 can only move along the track of the second track 4 and cannot swing left and right. Therefore, the swing of the vehicle parking mechanism 2 is limited.

[0038] The embodiment has the beneficial effects that the first track 3 and the second track 4 are arranged. The track of the vehicle parking mechanism 2 is parallel to the track of the lifting cycle mechanism 1. Therefore, the surface of the vehicle parking mechanism 2 parking the vehicle can be basically parallel to the horizontal plane without swinging in the whole operation process. Therefore, the previous swing and tilt of the vehicle parking mechanism 2 are calibrated and limited. Therefore, the safety of parking the vehicle is improved.

[0039] Preferably, the first block 30 and the second block 40 are both cylindrical. The circular arc surface of the first block 30 is in contact with the side wall of the first track 3. The circular arc surface of the second block 40 is in contact with the side wall of the second track 4. Specifically, since the first track 3 and the second track 4 both have the part from the vertical segment into the circular arc segment and the part from the circular arc segment into the vertical segment, in order to enable the first block 30 to stably run in the first track 3 without being hindered and the second block 40 to stably run in the second track 4 without being hindered, in the embodiment, the first block 30 and the second block 40 are both preferably cylindrical. The first block 30 is in linear contact with the side wall of the first track 3. The second block 40 is also in linear contact with the side wall of the second track 4. Therefore, the first block 30 and the second block 40 can stably run without being hindered in the movement process.

[0040] Preferably, the vehicle carrying mechanism 2 comprises a plurality of support rods 20 corresponding to the plurality of first blocks 30 and fixedly connected with the first blocks 30, and each support rod 20 is swingably connected with a pull frame 21 at both axial ends of the support rod 20, and the two pull frames 21 jointly suspend a vehicle carrying plate 22 for carrying a vehicle, the vertical ascending section of the first track 3 coincides with the vertical ascending section of the second track 4, and the vertical descending section of the first track 3 coincides with the vertical descending section of the second track 4; in particular, the support rod 20 is fixedly connected with the corresponding first block 30, the rod body 5 is connected with the vehicle carrying plate 22, each rod body 5 is fixedly connected with a second block 40, and from the horizontal direction, the support rod 20 is parallel to the rod body 5 at the corresponding position, and from the vertical direction, the projections of the two coincide, so that during the movement of the vehicle carrying plate 22, the rod body 5 and the support rod 20 always maintain the above-mentioned position unchanged, whether in the vertical ascending section or the vertical descending section, or in the circular arc section, so that the vehicle carrying plate 22 can stably park the vehicle without swinging, and because the first block 30 and the second block 40 are respectively connected with the vehicle carrying mechanism 2 at different positions, that is, the vertical sections of the first track 3 and the second track 4 are parallel and coincide, the circular arc sections of the first track 3 and the second track 4 are parallel from the vertical direction, and the circular arc section of the second track 4 is located below the circular arc section of the first track 3 and parallel to each other.

[0041] Preferably, the width of the first track 3 is smaller than the width of the second track 4, and the depth of the first track 3 is greater than the depth of the second track 4; in particular, because the first track 3 and the second track 4 have a coinciding part, in order to avoid the second block 40 entering the first track 3, the width of the first track 3 is smaller than the width of the second track 4, and the radial dimension of the corresponding second block 40 is greater than the radial dimension of the first block, in order to avoid the first block 30 entering the second track 4, the depth of the first track 3 is greater than the depth of the second track 4, that is, the axial length of the first block 30 is greater than the axial length of the second block 40, so that during operation, the first block 30 and the second block 40 will run in the corresponding track.

[0042] Further, a plurality of protrusions 6 are arranged on the inner side walls of the vertical ascending section and the vertical descending section of the second track 4 in sequence along the length direction, a plurality of recesses 7 are arranged on the outer side walls of the vertical ascending section and the vertical descending section of the second track 4 in sequence along the length direction, and the plurality of protrusions 6 correspond to the plurality of recesses 7 one by one; the second block 40 is extruded by the protrusions 6 to enter the recesses 7 during the movement stroke, and the second block 40 stops moving in the vertical direction and stays at the lower end of the recess 7.

[0043] Specifically, when the chain transmission mechanism is in a static state without the need to park or take the vehicle, the vehicle carrying mechanism 2 is also in a static state. In the prior art, the entire vehicle carrying mechanism 2 mainly provides a pulling force by connecting the support rod 20 and the first block 30. After the vehicle is parked on the vehicle carrying plate 22, the required pulling force is greatly increased. Therefore, in the embodiment, when the chain transmission mechanism stops running each time, the second block 40 can be located between the protruding portion 6 and the recessed portion 7, and the second block 40 stays at the lower end of the recessed portion 7. The recessed portion 7 provides an upward supporting action on the second block 40. In this way, the vehicle carrying plate 22 not only has the support rod 20 and the first block 30 connected to provide a pulling force, but also has the support force provided by the corners of the recessed portion 7, so as to reduce the gravity of the vehicle carrying plate 22 borne by the support rod 20 and the first block 30. The length of the protruding portion 6 is less than the length of the recessed portion 7. The distance between the protruding portion 6 and the recessed portion 7 is equal to the width of the second track 4, that is, the cooperation of the protruding portion 6 and the recessed portion 7 is equivalent to changing a small part of the vertical section of the second track 4. When the second block 40 moves upward through the protruding portion 6 and the recessed portion 7 in the vertical upward section, the second block 40 will first offset outward, then move upward along the vertical direction, and then offset inward and move downward along the vertical direction. When the second block 40 moves downward through the protruding portion 6 and the recessed portion 7 in the vertical downward section, the second block 40 will first offset outward, then move downward along the vertical direction, and then offset inward and move upward along the vertical direction. Therefore, when the second block 40 stays at the lower end position of the recessed portion 7, the lower end of the recessed portion 7 can provide an upward supporting action on the second block 40.

[0044] In another embodiment of the present application, the vehicle carrying plate 22 is composed of four rectangular plates which are spliced correspondingly, that is, the vehicle carrying plate 22 is divided into four rectangular plates by a cross. Each of the pull frames 21 corresponds to hoist two rectangular plates, and the four rectangular plates are jointly arranged on a base 23 at the proximal corners. The base 23 is fixedly connected to the rod body 5. Each of the rectangular plates is provided with a swing piece 24 at the corner. The swing piece 24 is rotationally connected to the base 23. The swing direction of each of the rectangular plates on the base 23 is along the diagonal line of the rectangular plate and horizontally downward.

[0045] Specifically, in the prior art, the vehicle loading plate 22 is a whole structure, and each of the four corners is hoisted by the pull frame 21. In the use process of the vehicle loading plate 22, if the connection between the pull frame 21 and the vehicle loading plate 22 is loose or the pull frame 21 is directly broken, the whole vehicle loading plate 22 will be inclined due to uneven force, which will cause the vehicle to fall. In order to avoid the above situation, in the embodiment, the vehicle loading plate 22 is made into a split structure, that is, the whole vehicle loading plate 22 is divided into four rectangular plates, and the four rectangular plates correspond to the four wheels of the parked vehicle. In normal use, each pull frame 21 hoists two rectangular plates, and the four rectangular plates near the corners are arranged on a base 23, that is, each rectangular plate has two diagonal positions that mainly support. When one of the rectangular plates loses the pulling force of the pull frame 21, the rectangular plate will drive the swing piece 24 connected thereto to swing horizontally downward along the diagonal line of the rectangular plate (that is, when the rectangular plate is parallel to the horizontal plane, the diagonal line pointing to the center of the cross is also parallel to the horizontal plane, which is the initial position of the swing of the rectangular plate). That is, each swing piece 24 is arranged at one end of the diagonal line of the corresponding rectangular plate pointing to the center of the cross. The other end of the diagonal line is fixedly connected with the pull frame by a bolt. The swing piece 24 is a circular plate-shaped mechanism, which is rotationally connected with the base 23. That is, a circular plate-shaped groove corresponding to the shape of the swing piece 24 is formed in the base 23. In this way, the four wheels of the parked vehicle are supported by one rectangular plate, and the parked vehicle basically does not deviate from the designated parking point. That is, when the center of gravity of the vehicle on the vehicle loading plate does not deviate, the other three wheels are still supported by the corresponding rectangular plates, and as long as the remaining three rectangular plates do not have the same problem, the vehicle can be parked stably. Only the faulty rectangular plate needs to be repaired to continue to be used.

[0046] Further, each of the swing plates 24 is provided with a push plate 25, and the base 23 is provided with a limiting piece 26. In the horizontal downward swing stroke of one of the rectangular plates along its own diagonal, the swing plate 24 connected thereto pushes the limiting piece 26 to extrude the remaining limiting pieces, so that the swing of the remaining vehicle carrying plates 22 is limited. The limiting piece 26 comprises four push rods 260 corresponding to the four push plates 25. Each of the push rods 260 is connected with the base 23 through a first spring. Two adjacent push rods 260 are connected by a transmission rod 261. Each of the swing plates 24 is also provided with a limiting plug 262 sliding in the radial direction. In the sliding direction, the limiting plug 262 is connected with the swing plate 24 through a second spring. Along the swing path of the swing plate 24, the base 23 is provided with a limiting slot 263. When the structure composed of the four push rods 260 and the four transmission rods 261 is deformed due to the push of the push plate 25 at the corresponding position of one of the push rods 260, the remaining each of the push rods 260 extrudes the push plate 25 at the corresponding position. The limiting plug 262 is inserted into the limiting slot 263 to lock the swing of the swing plate 24.

[0047] Specifically, to avoid the fracture of one of the rectangular plates and the pull frame 21 connected thereto on the basis of the foregoing embodiment, two or more of the four wheels cannot be supported by the rectangular plates, and the vehicle may fall. Therefore, in the present embodiment, each of the swing plates 24 is provided with a push plate 25. The push plate 25 swings with the swing plate 24. Each of the swing plates 24 corresponds to a push rod 260. Adjacent push rods 260 are connected by a transmission rod 261. Each of the push rods 260 is connected with the connected transmission rod 261 by a hinged manner. The four push rods 260 and the four transmission rods 261 form an octagon with unequal adjacent sides. When the push rod 260 is not extruded by the push plate 25, under the elastic force of the first spring, the octagon is in a fully expanded state. There is a certain distance between each of the swing plates 24 and the corresponding push rod 260. When the swing plate 24 contacts the push rod 260 in the swing stroke, the wheel and the corresponding rectangular plate are at the critical point of being about to separate or not yet separated.

[0048] For the convenience of description, when one of the rectangular plates is fractured and the pull frame 21 connected thereto, the rectangular plate swings horizontally downward along the diagonal. The swing plate 24 drives the push plate 25 to extrude the corresponding push rod 260 in the swing stroke, which is named as No. 1. Then, according to the view angle, the remaining three push rods 260 are named as No. 2, No. 3 and No. 4 in sequence clockwise. Figure 7

[0049] ​When the first push plate 25 is pressed to gradually approach the center position of the base 23, due to the action of the transmission rod 261, the first push plate 25 will push the second and fourth push plates 25 to approach the corresponding push plate 25 until they contact. The movement of the second and fourth push plates 25 will push the third push plate 25 to approach the corresponding push plate 25 until they contact through the transmission rod 261 between the second and third push plates. After the second, third and fourth push plates 25 contact the corresponding push plate 25, the limiting block 262 on the swing piece 24 of the rectangular plate disengaged from the wheel is extended from the swing piece 24 under the action of the second spring force and inserted into the limiting slot 263. Since the swing direction of the push plate 25 can only follow the diagonal horizontal downward movement of the rectangular plate, even if the three rectangular plates are disconnected from the corresponding pull frame 21, the three rectangular plates cannot swing downward to disengage from the wheel. At this time, the parked vehicle is temporarily supported.

[0050] When two rectangular plates are disconnected from the corresponding pull frame 21 at the same time, two push rods 260 are pressed by the corresponding push plate 25. If the first and second or the first and fourth push plates 25 are pressed, the force angle between the two push plates 25 is 90 degrees, and the direction of the resultant force of the two push plates 25 will be along the angle bisector of the angle towards the center of the base 23. In this way, the third and fourth or the second and third push plates 25 will contact the corresponding push plate 25, and the movement distance of the first and second or the first and fourth push plates 25 will make the corresponding rectangular plate just reach the critical point of disengaging from the wheel. The fourth rectangular plate can still support the vehicle.

[0051] When three or four rectangular plates are disconnected from the corresponding pull frame 21 at the same time, the movement distance of the first, second, third and fourth push plates 25 is smaller, so that the swing distance of the four rectangular plates has not reached the critical point of disengaging from the wheel. In this way, the four rectangular plates can still support the vehicle.

[0052] As can be seen from the above, the swing of the rectangular plate can be realized by pushing the push rod 260 with the push plate 25 to limit the swing of the remaining rectangular plates. Thus, when the pull frame 21 is disconnected, temporary support can be provided for the vehicle to prevent the vehicle from falling and to provide safety guarantee for the maintenance of the equipment.

[0053] In another embodiment of the present application, the passive brake mechanism 8 comprises an extrusion gap 80 provided on the second block 40, a deformation layer 81 is provided at the extrusion gap 80, the protruding part 6 is provided on the vertical inner side wall of the second track 4 in the length direction and is connected with the first elastic member, and a locking mechanism is further provided between the protruding part 6 and the second track 4; when the equipment fails to operate, the vehicle plate 22 falls, the second block 40 falls to the position of the protruding part 6 and the recess 7, the deformation layer 81 hits the protruding part 6, the deformation layer 81 deforms to expose the extrusion gap 80, the locking mechanism removes the locking of the protruding part 6, and the protruding part 6 gradually deviates from the recess 7 under the pushing of the second block 40.

[0054] Specifically, in order to avoid the running failure of the circulating lifting mechanism 1, causing the vehicle plate 22 to fall, an emergency brake mechanism is provided in the prior art, which can stop the circulating lifting mechanism 1 in time to avoid falling accidents. The prior art has the problem that the existing emergency brake is a active brake, that is, a sensor is provided on the circulating lifting mechanism 1 to monitor the operation of the equipment. Once the equipment fails to operate, the sensor can transmit a signal to the brake mechanism to brake in emergency. If the circulating lifting mechanism 1 and the active brake mechanism both fail, the running failure of the circulating lifting mechanism 1 cannot be eliminated, which may cause very serious consequences. Obviously, the active emergency brake mechanism can be adapted as one of the brake mechanisms, but it is also necessary to consider how to realize the emergency brake in the above-mentioned situation.

[0055] Therefore, in the embodiment, a passive brake mechanism 8 is additionally provided to perform emergency braking when the above problem occurs, that is, the extrusion gap 80 on the second block 40 has the same shape as the upper end of the protruding part 6. In the normal operation state, a deformation layer 81 is arranged outside the extrusion gap 80 to prevent the extrusion gap 80 from abutting against the upper end of the protruding part 6 and limiting the movement of the second block 40 in the second track 4. When the second block 40 moves to the protruding part 6, the interaction between the protruding part 6 and the second block 40 causes the second block 40 to deviate from the original movement track and enter the track between the protruding part 6 and the recessed part 7. When the above problem occurs, the second block 40 is driven to quickly descend. At this time, the descending speed of the second block 40 is obviously faster than the normal operation speed. When the deformation layer 81 contacts the upper end of the protruding part 6, the instantaneous impact between them causes the deformation layer 81 to be depressed to expose the extrusion gap 80 to abut against the upper end of the protruding part 6 (normal movement is not enough to cause sufficient deformation of the deformation layer 81). At the same time, the locking mechanism removes the locking of the protruding part 6. The second block 40 pushes the protruding part 6 to descend together. The descending of the protruding part 6 compresses the first elastic member, the elastic force of the first elastic member is increased to achieve the buffering of the descending of the second block 40. After the protruding part 6 is completely offset from the recessed part 7, the distance between the protruding part 6 and the outer side wall of the second track 4 is smaller than the distance between the inner and outer side walls of the second track 4. Therefore, the second block 40 cannot continue to descend, thereby achieving the emergency braking of the sudden descending of the second block 40.

[0056] Preferably, the locking mechanism includes a slot 82 arranged on the inner side wall of the second track 4 and a plug rod 83 slidingly arranged on the protruding part 6, and a second elastic member is connected between the plug rod 83 and the protruding part 6 in the sliding direction of the plug rod 83. An extrusion rod 84 is slidingly arranged on the protruding part 6. A jacking rod 85 is arranged at the extrusion gap 80. In the exposure stroke of the extrusion gap 80, the jacking rod 85 pushes the extrusion rod 84 to extrude the plug rod 83 to separate from the slot 82.

[0057] Specifically, the top rod 85 is arranged in the extrusion gap 80, when the deformation layer 81 is not extruded and deformed, the deformation layer 81 is equivalent to wrapping the top rod 85 in the extrusion gap, the deformation layer 81 is provided with a hole for the top rod 85 to extend out of, in the stroke of the deformation layer 81 impacting the convex part 6 to be deformed and depressed, the extrusion gap 80 is gradually exposed, then the top rod 85 will also extend out of the hole, and the top rod 85 will contact the extrusion rod 84 and push it to move downward, the downward movement of the extrusion rod 84 will extrude the plug rod 83 to separate from the insertion slot 82, until the extrusion gap 80 is completely matched with the upper end of the convex part 6, that is, the critical point between the complete matching of the extrusion gap 80 and the upper end of the convex part 6, if the deformation distance of the deformation layer 81 needs to be deformed to 10 cm for complete matching, when the distance between the extrusion gap 80 and the convex part 6 is 1 cm left for complete matching, the plug rod 83 will completely separate from the insertion slot 82, that is, the locking of the convex part 6 is completely released, then the second block 40 will drive the convex part 6 to move downward together, in which the extrusion rod 84 extruding the plug rod 83 can drive the plug rod 83 to separate from the insertion slot 82, that is, the extrusion rod 84 is provided with a first wedge surface 840, the plug rod 83 is provided with a second wedge surface 830, when the extrusion rod 84 does not extrude the plug rod 83, the lower end of the first wedge surface 840 is in contact with the upper end of the second wedge surface 830, when the extrusion rod 84 extrudes the plug rod 83, the lower end of the first wedge surface 840 moves downward along the vertical direction, extruding the second wedge surface 830, the extrusion force will generate a component force on the second wedge surface 830 in the direction of the plug rod 83 separating from the insertion slot 82, so that the lower end of the second wedge surface 830 gradually contacts the lower end of the first wedge surface 840, that is, in this process, the plug rod 83 moves to separate from the insertion slot 82, so that the locking of the convex part 6 is released, the second block 40 drives the convex part 6 to move downward together, the downward movement of the convex part 6 compresses the first elastic member, the elastic force of the first elastic member increases to realize the buffering of the downward movement of the second block 40, after the convex part 6 is completely overlapped with the recessed part 7, the distance between the convex part 6 and the outer side wall of the second track 4 is less than the distance between the inner and outer side walls of the second track 4, so that the second block 40 cannot continue to move downward, thereby realizing the emergency braking of the sudden downward movement of the second block 40.

[0058] The above only describes certain exemplary embodiments of the present application in a descriptive manner, it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of the claims of the present application.
