DETAILED DESCRIPTION

[0031] like Figures 1 to 14 As shown,

[0032] A bicycle parking device comprises a support column 1 and a parking rack 2.

[0033] The support 1 is arranged vertically, the parking frame 2 is arranged horizontally and the inner end is arranged on the support 1 through a sliding seat 2.1 to be vertically slidable. The lower part of the parking frame 2 is provided with a switch assembly 3, which limits the sliding seat 2.1 and the support 1.

[0034] A driving assembly 4, a pulley assembly 5, and a steel wire rope 6 are arranged in the pillar 1. The driving assembly 4 includes a light-loaded suspension rod 4.1, a heavy-loaded suspension plate 4.2, a locking mechanism 4.3, a light-loaded spring group 4.4, and a heavy-loaded spring group 4.5. The light-loaded suspension rod 4.1 is arranged through the heavy-loaded suspension plate 4.2, and the heavy-loaded suspension plate 4.2 can drive the light-loaded suspension rod 4.1 to move downward, and the light-loaded suspension rod 4.1 can drive the heavy-loaded suspension plate 4.2 to move upward.

[0035] The light-load spring group 4.4 is connected to the light-load suspension rod 4.1 and elastically drives the light-load suspension rod 4.1 to move downward. The heavy-load spring group 4.5 is connected to the heavy-load suspension plate 4.2 and elastically drives the heavy-load suspension plate 4.2 to move downward. The locking mechanism 4.3 is arranged between the heavy-load suspension plate 4.2 and the support 1 and is used to limit the heavy-load suspension plate 4.2 to move downward relative to the support 1.

[0036] The light load suspension rod 4.1 is connected to the pulley assembly 5, and the wire rope 6 passes through the pulley assembly 5 and is connected to the sliding seat 2.1.

[0037] The switch assembly 3 includes a safety structure 3.1, which includes a foot switch 3.1.1, a mounting seat 3.1.2, a safety lock tongue 3.1.3, a safety connecting rod 3.1.4, and a safety lock block 3.1.5.

[0038] The mounting seat 3.1.2 is arranged at one side of the parking rack 2, the foot switch 3.1.1 is rotatably arranged in the mounting seat 3.1.2, the safety lock tongue 3.1.3 is arranged at the inner end of the parking rack 2, the safety connecting rod 3.1.4 connects the foot switch 3.1.1 and the safety lock tongue 3.1.3, and the safety lock block 3.1.5 is arranged on the pillar 1 to cooperate with the safety lock tongue 3.1.3. The foot is driven to rotate in the first direction and the foot switch 3.1.1 and the mounting seat 3.1.2 are limited to pull the safety lock tongue 3.1.3 and the safety lock block 3.1.5 to release the cooperation,

[0039] The switch assembly 3 also includes a reset structure 3.2, which includes a reset block 3.2.1 arranged on one side of the pillar 1 and a reset rod 3.2.2 arranged on one side of the safety link 3.1.4. When the safety lock tongue 3.1.3 cooperates with the safety lock block 3.1.5, the reset rod 3.2.2 is staggered from the reset surface 3.2.1.2. After the foot switch 3.1.1 and the mounting seat 3.1.2 are limited, the reset block 3.2.1 and the reset rod 3.2.2 correspond to each other in the vertical position.

[0040] The reset block 3.2.1 includes a movable surface 3.2.1.1 arranged at the bottom and a reset surface 3.2.1.2 arranged at the top. When the reset rod 3.2.2 moves upward with the parking rack 2, it abuts against the movable surface 3.2.1.1 and drives the reset block 3.2.1 to rotate, and the reset block 3.2.1 avoids the reset rod 3.2.2. When the reset rod 3.2.2 moves downward with the parking rack 2, it abuts against the reset surface 3.2.1.2. The reset block 3.2.1 is restricted from rotating by the reset seat 3.2.3 and drives the reset rod 3.2.2 to rotate in the second direction. After the safety link 3.1.4 rotates, the foot switch 3.1.1 is released from the mounting seat 3.1.2, and the safety lock tongue 3.1.3 moves to cooperate with the safety lock block 3.1.5.

[0041] The first direction is opposite to the second direction.

[0042] When the parking rack 2 is in a light-load state, that is, when no bicycle is placed on the parking rack 2, the heavy-load hanging plate 4.2 is limited by the locking mechanism 4.3 and the support 1, the switch assembly 3 is unlocked, and the light-load spring group 4.4 pulls the light-load hanging rod 4.1 downward and pulls the parking rack 2 upward through the wire rope 6.

[0043] The parking rack 2 is in a heavy-load state, that is, after the parking rack 2 is placed with a bicycle, the foot switch 3.1.1 is unlocked, the safety lock tongue 3.1.3 and the safety lock block 3.1.5 are released, the bicycle is pressed and the parking rack 2 is driven to move downward, the light-loaded suspension rod 4.1 pulls the heavy-loaded suspension plate 4.2 to move upward and drives the locking mechanism 4.3 and the support 1 to release the limit, the parking rack 2 is no longer pressed, the heavy-loaded spring group 4.5 pulls the heavy-loaded suspension plate 4.2 downward and at the same time the light-loaded spring group 4.4 pulls the light-loaded suspension rod 4.1 downward, and the heavy-loaded spring group 4.5 and the light-loaded spring group 4.4 simultaneously pull the parking rack through the wire rope 6 2 moves upward. During the upward movement, the reset block 3.2.1 will not drive the reset rod 3.2.2 to rotate, and the foot switch 3.1.1 always maintains the limit state with the mounting seat 3.1.2. When the parking rack 2 moves downward from the upper layer, the reset block 3.2.1 drives the reset rod 3.2.2 to rotate. After the safety connecting rod 3.1.4 rotates, the foot switch 3.1.1 and the mounting seat 3.1.2 are released, and the safety lock tongue 3.1.3 moves to cooperate with the safety lock block 3.1.5. The foot switch 3.1.1 returns to its initial position and moves to the lower layer to cooperate and lock with the safety lock block 3.1.5.

[0044] The safety lock block 3.1.5 includes a horizontally arranged blocking surface and an obliquely arranged passing surface. There are three safety lock blocks 3.1.5, which are the first lock block 3.1.5.1, the second lock block 3.1.5.2, and the third lock block 3.1.5.3 from bottom to top. The first lock block 3.1.5.1 and the second lock block 3.1.5.2 are arranged at the lower part of the pillar 1, and the third lock block 3.1.5.3 is arranged at the middle part of the pillar 1.

[0045] The blocking surface of the first locking block 3.1.5.1 is on the top and the passing surface is on the bottom. The first locking block 3.1.5.1 cooperates with the safety lock tongue 3.1.3 to limit the maximum distance that the parking rack 2 moves downward. The blocking surface of the second locking block 3.1.5.2 is on the bottom and the passing surface is on the top. The second locking block 3.1.5.2 cooperates with the safety lock tongue 3.1.3 to limit the parking rack 2 to the lower layer. The blocking surface of the third locking block 3.1.5.3 is on the top and the passing surface is on the bottom. The third locking block 3.1.5.3 cooperates with the safety lock tongue 3.1.3 to limit the parking rack 2 to the upper layer.

[0046] After the bicycle is placed in the parking rack 2, pressing the parking rack 2 downward will unlock the locking mechanism 4.3 between the heavy-load hanging plate 4.2 and the pillar 1. At this time, if the user does not want to park and pushes the bicycle out of the parking rack 2, the heavy-load spring group 4.5 and the light-load spring group 4.4 will pull the parking rack 2 up quickly together, causing a safety accident. Therefore, the safety lock tongue 3.1.3 of the safety structure 3.1 cooperates with the first lock block 3.1.5.1 to limit the downward movement of the parking rack 2 to avoid unlocking the heavy-load hanging plate 4.2 due to misoperation by the personnel. If the parking rack 2 with the placed bicycle needs to be moved to the upper level, the foot switch 3.1.1 needs to be driven by the foot to unlock the safety lock tongue 3.1.3 and the safety lock block 3.1.5, and then the bicycle can be lifted up after being pressed. The foot drive in the process is a link that the user confirms before the operation, making the entire operation process safer.

[0047] Among them, the safety structure 3.1 also includes a first return spring 3.7, which is arranged between the mounting seat 3.1.2 and the safety link 3.1.4 and drives the safety link 3.1.4 to return inward, the outer end of the safety link 3.1.4 is rotatably arranged in the mounting seat 3.1.2, and the foot switch 3.1.1 is arranged at the outer end of the safety link 3.1.4 and is arranged along the radial direction of the safety link 3.1.4; the first return spring 3.7 is used to provide elastic force for resetting the foot switch 3.1.1, and the outer peripheral wall of the safety link 3.1.4 protrudes a mounting ring, the inner end of the first return spring 3.7 is against the mounting ring, and the outer end is against the mounting seat 3.1.2.

[0048] The outer end of the mounting seat 3.1.2 is provided with a safety card block 3.1.2.1 for cooperating with the foot switch 3.1.1. The operator drives the foot switch 3.1.1 with his foot to drive the safety link 3.1.4 to be pulled outward, and rotates the safety link 3.1.4 to make the foot switch 3.1.1 cooperate with the safety card block 3.1.2.1, and keep the safety lock tongue 3.1.3 and the safety lock block 3.1.5 in an unlocked state. The outer end surface of the safety card block 3.1.2.1 abuts against the inner end surface of the foot switch 3.1.1 to limit the inward movement of the safety link 3.1.4, and the side wall of the safety card block 3.1.2.1 abuts against the side wall of the foot switch 3.1.1 to limit the maximum angle of rotation of the foot switch 3.1.1 along the first direction.

[0049] like Figure 13-14 , the reset block 3.2.1 is a triangular structure, the reset block 3.2.1 also includes a limit surface 3.2.1.3 connecting the reset surface 3.2.1.2 and the movable surface 3.2.1.1, the reset surface 3.2.1.2 is horizontally arranged on the top, and the movable surface 3.2.1.1 is inclined at the bottom, the reset block 3.2.1 also includes a limit surface 3.2.1.3 connecting the reset surface 3.2.1.2 and the movable surface 3.2.1.1, the limit surface 3.2.1.3 is opposite to the side wall of the reset seat 3.2.3, the reset block 3.2.1 is hinged with the reset seat 3.2.3, the hinge is located at the junction of the limit surface 3.2.1.3 and the reset surface 3.2.1.2, the distance from the hinge center to the junction of the limit surface 3.2.1.3 and the reset surface 3.2.1.2 is less than the gap between the limit surface 3.2.1.3 and the side wall of the reset seat 3.2.3, so Fig.13 When the reset rod 3.2.2 contacts the movable surface 3.2.1.1 of the reset block 3.2.1 from bottom to top, the reset block 3.2.1 can rotate relative to the reset seat 3.2.3, and the reset block 3.2.1 will not affect the position of the reset rod 3.2.2. Fig.14 When the middle reset rod 3.2.2 abuts against the movable surface 3.2.1.1 of the reset block 3.2.1 from top to bottom, the limit surface 3.2.1.3 abuts against the side wall of the reset seat 3.2.3, and the reset block 3.2.1 cannot rotate. At this time, the reset block 3.2.1 drives the reset rod 3.2.2 to rotate in the second direction, the cooperation between the foot switch 3.1.1 and the insurance card block 3.1.2.1 is released, and the first reset spring 3.7 drives the insurance link 3.1.4 to return to the initial position, and the insurance lock tongue 3.1.3 cooperates with the insurance lock block 3.1.5.

The switch lock block 3.6 is arranged at the lower part of the pillar 1, with the blocking surface of the switch lock block 3.6 at the bottom and the passing surface at the top to restrict the parking rack 2 to the lower layer.

[0061] The reset seat 3.2.3 and the reset block 3.2.1 can be set in two groups, one group is on the upper layer of the support 1, and the other group is on the lower layer of the support 1. The specific setting positions are:

[0062] After the bicycle moves upward with the parking rack 2, in order to restrict the parking rack 2 to the upper layer, when the reset block 3.2.1 of the upper layer drives the reset rod 3.2.2 to move in the second direction, the safety link 3.1.4 is reset. At this time, the reset position of the safety lock tongue 3.1.3 should be a little above the blocking surface of the third lock block 3.1.5.3. The safety lock tongue 3.1.3 and the safety lock block 3.1.5 need to be unlocked by pressing the handle switch 3.3 by hand.

[0063] When the parking rack 2 moves to the lower layer, the reset block 3.2.1 of the lower layer drives the reset rod 3.2.2 to move in the second direction, and the safety link 3.1.4 is reset. At this time, the reset position of the safety lock tongue 3.1.3 should be a distance above the blocking surface of the first lock block 3.1.5.1 and a distance below the second lock block 3.1.5.2, so that the first lock block 3.1.5.1 can limit the parking rack 2 from continuing to move downward and unlock the heavy-load hanger 4.2, and the second lock block 3.1.5.2 can limit the parking rack 2 from being lifted.

[0064] When the user pushes the bicycle into the parking rack 2 and unlocks it by driving the foot switch 3.1.1 with his foot, and wants to take the bicycle back when the bicycle is halfway upward, the heavy-load hanging plate 4.2 is still in the unlocked state, and the parking rack 2 is moved downward until the reset rod 3.2.2 contacts the reset block 3.2.1 of the lower layer, and the safety lock block 3.1.5 is reset. The first lock block 3.1.5.1 limits the downward movement of the parking rack 2, and the second lock block 3.1.5.2 limits the upward movement of the parking rack 2. At this time, pushing the bicycle out of the parking rack 2 can prevent the heavy-load hanging plate 4.2 in the unlocked state from lifting the parking rack 2 quickly.

[0065] The inner end of the parking frame 2 is slidably set on the outside of the pillar 1 through a sliding seat 2.1. A roller is provided on the sliding seat 2.1. A track cooperating with the roller is provided on the outside of the pillar 1. The sliding cooperation between the roller and the track is the prior art. The switch assembly 3 is set at the outer end of the parking frame 2. The limit between the sliding seat 2.1 and the pillar 1 is released by pulling the switch assembly 3. An installation cavity is provided inside the pillar 1, and the drive assembly 4, the pulley assembly 5, and the wire rope 6 are all set in the installation cavity.

[0066] The outer peripheral protrusion of the light-loaded hanger rod 4.1 is provided with a protrusion 4.1.1, and the upper end surface of the protrusion 4.1.1 is abutted against the lower end surface of the heavy-loaded hanger plate 4.2. When the light-loaded hanger rod 4.1 moves downward relative to the heavy-loaded hanger plate 4.2 or the heavy-loaded hanger plate 4.2 moves upward relative to the light-loaded hanger rod 4.1, the heavy-loaded hanger plate 4.2 and the light-loaded hanger rod 4.1 are not limited. When the light-loaded hanger rod 4.1 moves upward relative to the heavy-loaded hanger plate 4.2 or the heavy-loaded hanger plate 4.2 moves downward relative to the light-loaded hanger rod 4.1, the upper end surface of the protrusion 4.1.1 is abutted against the lower end surface of the heavy-loaded hanger plate 4.2, and the heavy-loaded hanger plate 4.2 and the light-loaded hanger rod 4.1 are limited at this time. Therefore, the heavy-loaded hanger plate 4.2 can drive the light-loaded hanger rod 4.1 to move downward, and the light-loaded hanger rod 4.1 can drive the heavy-loaded hanger plate 4.2 to move upward.

[0067] The locking mechanism 4.3 includes a movable locking block 4.3.1, a fixed locking block 4.3.2, and a driving locking block 4.3.3. The movable locking block 4.3.1 is arranged on the heavy-load hanging plate 4.2 and can extend relative to the heavy-load hanging plate 4.2 and limit with the fixed locking block 4.3.2, or retract and release the limit with the fixed locking block 4.3.2.

[0068] The fixed locking block 4.3.2 is fixedly set on the inner wall of the pillar 1, and the driving locking block 4.3.3 is set on the inner wall of the pillar 1 and is set above the fixed locking block 4.3.2. In the light-load state, the movable locking block 4.3.1 extends relative to the heavy-loaded hanger plate 4.2 and limits the heavy-loaded hanger plate 4.2 with the fixed locking block 4.3.2 to limit the heavy-loaded hanger plate 4.2 from moving downward. In the heavy-load state, the parking rack 2 is pressed downward. When the heavy-loaded hanger plate 4.2 moves upward, the driving locking block 4.3.3 drives the movable locking block 4.3.1 to retract relative to the heavy-loaded hanger plate 4.2, and the limit of the movable locking block 4.3.1 and the fixed locking block 4.3.2 is released, and the heavy-loaded hanger plate 4.2 moves downward.

[0069] A limit block 4.3.4 is provided above the driving lock block 4.3.3. The side wall of the driving lock block 4.3.3 close to the movable lock block 4.3.1 is a driving angle 4.3.3.1 set obliquely downward. The side wall of the movable lock block 4.3.1 corresponding to the driving angle 4.3.3.1 is provided with a driven angle 4.3.1.1 set obliquely downward.

[0070] When the parking rack 2 is in a light-load state, the driving angle 4.3.3.1 is located above the driven angle 4.3.1.1, that is, the driving angle 4.3.3.1 abuts against the side wall of the driven angle 4.3.1.1, and the lower end surface of the driven angle 4.3.1.1 abuts against the upper end surface of the fixed locking block 4.3.2. The heavy-load hanging plate 4.2 is restricted from moving downward by the fixed locking block 4.3.2.

[0071] When the parking rack 2 is in the overload state, the parking rack 2 is pressed, and the movable lock block 4.3.1 moves upward with the overload hanging plate 4.2, and the movable lock block 4.3.1 drives the driving lock block 4.3.3 to move upward until the driving lock block 4.3.3 abuts against the limit block 4.3.4, and the movable lock block 4.3.1 continues to move upward, and the driving angle 4.3.3.1 abuts against the side wall of the driven angle 4.3.1.1 and drives the movable lock block 4.3.1 to retract into the overload hanging plate 4.2.

[0072] The movable locking block 4.3.1 moves to the upper part of the driving locking block 4.3.3, and the driving locking block 4.3.3 moves downward with gravity until it is against the fixed locking block 4.3.2, and the driven angle 4.3.1.1 is against the side wall of the driving angle 4.3.3.1, and the pressing of the parking rack 2 is cancelled. The heavy-load spring group 4.5 pulls the heavy-load hanging plate 4.2 downward, and the side wall of the driving angle 4.3.3.1 is against the lower end surface of the driven angle 4.3.1.1 and drives the movable locking block 4.3.1 to retract the heavy-load hanging plate 4.2, and the movable locking block 4.3.1 moves downward and passes over the fixed locking block 4.3.2.

[0073] A second driving surface 4.3.2.1 is provided at the lower part of the fixed locking block 4.3.2. When the movable locking block 4.3.1 moves upward from the lower part of the fixed locking block 4.3.2, the second driving surface 4.3.2.1 drives the driven angle 4.3.1.1 to make the movable locking block 4.3.1 retract the heavy-load hanging plate 4.2.

[0074] There are two locking mechanisms 4.3, which are respectively arranged on both sides of the upper part of the heavy-load hanging plate 4.2. A transversely arranged locking block spring 4.3.6 is arranged between the two movable locking blocks 4.3.1. The locking block spring 4.3.6 elastically drives the movable locking block 4.3.1 to extend out of the heavy-load hanging plate 4.2.

[0075] The principle of bicycle parking equipment is:

[0076] Under light load condition, Figures 2 to 5 As shown, no bicycle is placed on the parking rack 2, the driven angle 4.3.1.1 of the movable lock block 4.3.1 is between the driving lock block 4.3.3 and the fixed lock block 4.3.2, the lower end surface of the movable lock block 4.3.1 is against the upper end surface of the fixed lock block 4.3.2, the fixed lock block 4.3.2 limits the heavy load hanging plate 4.2 to move downward, the light load hanging rod 4.1 can move downward relative to the heavy load hanging plate 4.2, at this time, the light load spring group 4.4 participates in the lifting of the sliding seat 2.1, and the heavy load spring group 4.5 does not participate in the lifting of the sliding seat 2.1, and at the same time, Figure 3 and Figure 4It can be seen in. The support block 3.5.1.1 does not drive the switch lock tongue 3.4 and the switch lock block 3.6 to unlock, the foot switch 3.1.1 does not drive the safety lock tongue 3.1.3 and the safety switch to unlock, the safety lock tongue 3.1.3 is located between the blocking surface of the first lock block 3.1.5.1 and the blocking surface of the second lock block 3.1.5.2, the switch lock tongue 3.4 is located below the blocking surface of the switch lock block 3.6, directly press the handle switch 3.3, and the light-load spring group 4.4 can drive the parking rack 2 from the lower layer to the upper layer;

[0077] Under heavy load, push the bicycle into the parking rack 2, as shown in Figures 7 to 9 As shown, after the bicycle is completely in the parking rack 2, due to the gravity of the bicycle, the parking rack 2 will drive the heavy-load hanging plate 4.2 to move downward a certain distance, and the locking mechanism 4.3 is as shown in FIG. Figure 7 As shown, the sliding seat 2.1 pulls the wire rope 6 downwards and at the same time the wire rope 6 pulls the light load suspension rod 4.1 upwards through the pulley block, and the light load suspension rod 4.1 drives the heavy load suspension plate 4.2 to move upwards, and the lower end surface of the movable lock block 4.3.1 is separated from the lower end surface of the fixed lock block 4.3.2. At this time, the movable lock block 4.3.1 drives the driving lock block 4.3.3 to move upwards until the driving lock block 4.3.3 is against the limit block 4.3.4, as shown in FIG. Figure 8 , Fig. 9 As shown, at this time, the support block 3.5.1.1 rotates, the rotating block 3.5.1.2 drives the connecting plate 3.5.5, and the connecting plate 3.5.5 pulls the switch lock tongue 3.4 to unlock the switch lock block 3.6. At this time, if the user presses the bicycle, the lower end surface of the safety lock tongue 3.1.3 will still be against the blocking surface of the first lock block 3.1.5.1, and the heavy-load hanging plate 4.2 cannot move downward;

[0078] The user drives the foot switch 3.1.1 with his foot to unlock the safety lock tongue 3.1.3 and the safety lock block 3.1.5. The user presses the bicycle and the parking rack 2 continues to move downward. Fig.11As shown, at this time, the heavy-loaded hanging plate 4.2 continues to move upward, and the driving angle 4.3.3.1 of the driving lock block 4.3.3 pushes the driven surface of the movable lock block 4.3.1, and the movable lock block 4.3.1 retracts the heavy-loaded hanging plate 4.2 until the movable lock block 4.3.1 moves above the driving lock block 4.3.3, and the driving lock block 4.3.3 moves downward with gravity, and the side wall of the driving angle 4.3.3.1 is against the lower end surface of the driven angle 4.3.1.1, and the pressure on the bicycle is cancelled. The heavy-loaded spring group 4.5 pulls the heavy-loaded hanging plate 4.2 downward. Since the distance a from the side wall of the driving lock block 4.3.3 close to the movable lock block 4.3.1 to the center of the heavy-loaded hanging plate 4.2 is fixed, the fixed lock block 4.3.3 .2 The distance from the side wall close to the movable locking block 4.3.1 to the center of the heavy-load hanging plate 4.2 is b, and a is greater than b, that is, the side wall of the driving locking block 4.3.3 protrudes from the side wall of the fixed locking block 4.3.2. Therefore, when the movable locking block 4.3.1 moves downward with the heavy-load hanging plate 4.2, it can be directly moved from the side wall of the driving angle 4.3.3.1 to the side wall of the fixed locking block 4.3.2, and then move downward. During the process, the heavy-load hanging plate 4.2 is always pulled by the heavy-load spring group 4.5, and the heavy-load hanging plate 4.2 also synchronously pulls the light-load hanging rod 4.1 downward. At this time, the heavy-load spring group 4.5 and the light-load spring group 4.4 are simultaneously involved in lifting the parking rack 2. At this time, the bottom of the parking rack 2 is as shown in Fig.11 As shown, the safety lock tongue 3.1.3 and the safety lock block 3.1.5 are released from the limit, and the switch lock tongue 3.4 and the switch lock block 3.6 are released from the limit.

[0079] When the parking rack 2 moves to the upper layer, the locking mechanism 4.3 is as follows Fig.12 shown.

[0080] When the parking rack 2 moves downward, the reset rod 3.2.2 abuts against the reset block 3.2.1, and the reset block 3.2.1 drives the reset rod 3.2.2 to rotate in the second direction, and the safety lock tongue 3.1.3 returns to the position matched with the safety lock block 3.1.5. At this time, the bottom of the parking rack 2 is Fig. 9 shown.

[0081] When the parking rack 2 is reset from the upper layer to the lower layer of the pillar 1, the heavy-loaded hanging plate 4.2 moves upward from the bottom of the fixed locking block 4.3.2, and the second driving surface 4.3.2.1 at the bottom of the fixed locking block 4.3.2 drives the movable locking block 4.3.1 to retract the heavy-loaded hanging plate 4.2. When the movable locking block 4.3.1 passes the side wall of the fixed locking block 4.3.2 and the driven surface of the movable locking block 4.3.1 abuts against the driving angle 4.3.3.1 of the driving locking block 4.3.3, the movable locking block 4.3.1 extends relative to the heavy-loaded hanging plate 4.2, and the driving locking block 4.3.3 is pushed upward, and the lower end surface of the movable locking block 4.3.1 abuts against the upper end surface of the fixed locking block 4.3.2 to complete the reset.

[0082] Among them, a vertical movable rod 4.3.5 is provided on the upper part of the fixed locking block 4.3.2, and a movable hole is provided in the center of the driving locking block 4.3.3 to cooperate with the movable rod 4.3.5. The movable rod 4.3.5 cooperates with the movable hole, so that the driving locking block 4.3.3 moves above the fixed locking block 4.3.2 in a guided manner.

[0083] Among them, the driving angle 4.3.3.1 is extended downwardly and is provided with a stopper 4.3.3.2. When the driving lock block 4.3.3 abuts against the fixed lock block 4.3.2, the stopper 4.3.3.2 is located on the outer side of the side wall of the fixed lock block 4.3.2. When the heavy-loaded hanging plate 4.2 moves downward, the stopper 4.3.3.2 can prevent the movable lock block 4.3.1 from being stuck into the gap between the driving lock block 4.3.3 and the fixed lock block 4.3.2, thereby ensuring that the movable lock block 4.3.1 moves downward smoothly; when the heavy-loaded hanging plate 4.2 moves upward, the movable lock block 4.3.1 abuts against the stopper 4.3.3.2 and drives the driving lock block 4.3.3 to move upward, so that the movable lock block 4.3.1 extends between the driving lock block 4.3.3 and the fixed lock block 4.3.2, thereby returning to its initial state.

[0084] Among them, the two movable locking blocks 4.3.1 include a first movable block 4.3.1.2 and a second movable block 4.3.1.3. The inner end of the first movable block 4.3.1.2 is provided with a first sliding portion 4.3.1.21, a first mounting column 4.3.1.22, and a first sliding groove 4.3.1.23. The inner end of the second movable block 4.3.1.3 is provided with a second sliding portion 4.3.1.31, a second mounting column 4.3.1.32, and a second sliding groove 4.3.1.33. The first sliding portion 4.3.1.21 is arranged at the upper part of the first sliding groove 4.3.1.23, the first mounting column 4.3.1.22 is arranged at the inner end of the first sliding portion 4.3.1.21, the second sliding portion 4.3.1.31 is arranged at the lower part of the second sliding groove 4.3.1.33, the second mounting column 4.3.1.32 is arranged at the inner end of the second sliding portion 4.3.1.31, and the first sliding portion The movable part 4.3.1.21 slides in the second sliding groove 4.3.1.33, and the second sliding part 4.3.1.31 slides in the first sliding groove 4.3.1.23. The locking block spring 4.3.6 is a tension spring arranged between the first mounting column 4.3.1.22 and the second mounting column 4.3.1.32. By setting the above structure, the two movable locking blocks 4.3.1 can be made more compact in height, and the first sliding groove 4.3.1.23 guides the sliding of the second sliding part 4.3.1.31, and the second sliding groove 4.3.1.33 guides the sliding of the first sliding part 4.3.1.21, so that the sliding fit is more accurate. At the same time, the locking block spring 4.3.6 is installed between the first mounting column 4.3.1.22 and the second mounting column 4.3.1.32, and is arranged on the outside of the movable locking block 4.3.1, which is more convenient for installation and disassembly and replacement.

[0085] The driving assembly 4 further comprises a spring base 4.6 arranged at the bottom of the pillar 1, the heavy-load spring group 4.5 is a plurality of tension springs arranged between the heavy-load hanger plate 4.2 and the spring base 4.6, and the light-load spring group 4.4 is a plurality of tension springs arranged between the light-load hanger rod 4.1 and the spring base 4.6.

[0086] The tension of the light-load spring group 4.4 is used to match the gravity of the parking rack 2 and the sliding seat 2.1, so that the user can save more effort when operating the parking rack 2 in a light-load state to move up. Generally, one tension spring can be selected to achieve this. The tension of the heavy-load spring group 4.5 is used to match the gravity of the bicycle, so that the user can save more effort when operating the parking rack 2 in a heavy-load state to move up. Generally, 2 to 6 tension springs can be selected to achieve this. The heavy-load spring group 4.5 and the light-load spring group 4.4 are arranged in the same vertical space, and the heavy-load spring group 4.5 is arranged around the light-load spring group 4.4 to correspond to the positions of the light-load hanger 4.1 and the heavy-load hanger plate 4.2, thereby making the structure more compact.

[0087] Among them, a hook is set at the lower end of the light-load suspension rod 4.1, a hook is also set at the lower end of the heavy-load suspension plate 4.2, a corresponding hook is set on the spring base 4.6, and both ends of the tension springs of the light-load spring group 4.4 and the heavy-load spring group 4.5 are connected to the hooks.
