Abstract
Description
Technical Field
[0001] This utility model relates to a mechanical lock for parking spaces, belonging to the field of mechanical lock technology. Background Technology
[0002] Existing locking methods in multi-level parking garages include hydraulic locks, electromagnetic locks, and electronic locks. Hydraulic locks rely on the pressure of a hydraulic cylinder to maintain position, but when there are leaks or other problems in the hydraulic system, the pressure drops, and the lock fails, posing a significant safety hazard. Furthermore, hydraulic systems are costly to maintain, requiring regular replacement of fluids and seals. Electromagnetic locks use electric current to generate magnetic force for fixation, but once the power is cut off, the magnetic force disappears, and the device may lose its lock, which is extremely dangerous during power outages. The magnetic force of electromagnetic locks is also highly susceptible to temperature or external magnetic field interference, affecting its stability. Electronic locks or sensor-based control systems, while highly intelligent, may have a higher failure rate due to their complexity. For example, sensor misjudgments or control system errors may lead to incorrect locking or unlocking, especially in humid or dusty environments where sensors are prone to malfunction. Therefore, designing a mechanical lock for parking spaces is essential. Utility Model Content
[0003] This utility model addresses the shortcomings of the existing technology by providing a mechanical lock for parking spaces.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0005] A mechanical lock for a parking space includes a base plate and a locking arm. The locking arm has rollers on the front and rear sides of its lower end and a safety claw on its lower right side. The safety claw has a slot in the middle and a rotatably connected travel plate in the slot. A stop block is provided on the lower right side of the safety claw. The base plate has a plurality of evenly arranged stop blocks located below the safety claw. Both the stop blocks and the stop blocks are parallelograms and have the same inclination direction.
[0006] Furthermore, the travel plate is in the shape of a right trapezoid, with the hypotenuse of the trapezoid corresponding to the stop block.
[0007] Furthermore, the safety claw is fixedly connected to the stop block.
[0008] Furthermore, the upper end of the travel plate is rotatably connected to the safety claw via a shaft spanning the slot.
[0009] Furthermore, several of the stop blocks are evenly arranged on the same center line.
[0010] Furthermore, the stop block and the stop block are similar in relationship.
[0011] Furthermore, the substrate is provided with a sliding groove.
[0012] Furthermore, the sliding groove has closed ends at both ends.
[0013] Compared with the prior art, the beneficial effects of this utility model are: when the lifting mechanism of the double-layer parking space or other similar lifting mechanism is correctly locked on the safety lock after it has risen, that is, when the stop block is stuck on the stop block, the weight of the vehicle on the lifting mechanism will press the platform securely on the safety lock without any additional hydraulic energy, thus reducing the cost of use. When the power supply is turned off or interrupted or the hydraulic system leaks, the safety lock will remain locked until the control system controller unlocks it. The operation is simple, the overall safety factor is high, and the use effect is good. Attached Figure Description

[0015] Figure 2 for Figure 1 A partial sectional view of section A when the mechanical lock is engaged.
[0016] Figure 3 for Figure 1 A partial cross-sectional view of the mechanical lock in section A when it is being unlocked.
[0017] In the diagram, 1 is the base plate; 2 is the sliding groove; 3 is the roller; 4 is the stop block; 5 is the stop block; 6 is the safety claw; 7 is the travel plate; and 8 is the locking arm. Detailed Implementation
[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0019] like Figures 1-3 As shown, the mechanical lock for parking spaces in this embodiment includes a base plate 1 and a locking arm 8. Rollers 3 are provided on the front and rear sides of the lower end of the locking arm 8, and a safety claw 6 is provided on the lower right side. A slot is provided in the middle of the safety claw 6, and a rotatably connected travel plate 7 is provided in the slot. A stop block 5 is provided on the lower right side of the safety claw 6. Several evenly arranged stop blocks 4 are provided on the base plate 1. The stop blocks 4 are located below the safety claw 6. Both the stop blocks 4 and the stop blocks 5 are parallelograms and have the same inclination direction.
[0020] The travel plate 7 is in the shape of a right trapezoid, with the hypotenuse of the right trapezoid corresponding to the stop block 4.
[0021] The safety claw 6 is fixedly connected to the stop block 5.
[0022] The upper end of the travel plate 7 is rotatably connected to the safety claw 6 via a shaft spanning the slot.
[0023] Several of the stop blocks 4 are evenly arranged on the same center line.
[0024] The stop block 4 and the stop block 5 are similar in nature.
[0025] The substrate 1 is provided with a sliding groove 2.
[0026] The sliding groove 2 has closed ends at both ends.
[0027] During operation, keep the base plate 1 and the mechanical lock clean. The lock is an automatic unlocking and locking mechanism. When the dual parking spaces or other similar lifting mechanisms rise or fall, the safety claw 6 is lifted by the action of the travel plate 7 (hereinafter referred to as...). Figure 1 (From the perspective of direction);
[0028] When the up button is pressed, the lock is in the unlocked state. The lock moves to the right from its initial or locked position. The locking arm 8 drives the roller 3 to move to the right until the stop block 5 encounters the stop block 4. Then, the travel plate 7 tilts, causing the stop block 5 and the safety claw 6 to pass over the stop block 4 in sequence. When the stop block 5 passes over a stop block 4, an audible "click" sound is emitted because the stop block 5 contacts the base plate 1. The locking arm 8, in conjunction with the scissor arm, causes the upper parking space or platform to gradually rise. This continues to move to the right until the appropriate height is reached, at which point the stop block 5 is engaged with the stop block 4 (e.g., ...). Figure 2 As shown, it is currently in a locked state;
[0029] When the descent button is pressed, the lock is in the unlocked state. After the lock moves to the right from its current initial position or locked position and then to the left, the locking arm 8 drives the roller 3 to move to the left until the travel plate 7 contacts the stop block 4 and stands upright, simultaneously raising the stop block 5 and the safety claw 6 past the stop block 4 (e.g., Figure 3 As shown, when the stop block 5 passes a stop block 4, an audible "click" sound is emitted because the stop block 5 contacts the base plate 1 until it is fully lowered to the lowest position.
[0030] When the lifting mechanism of the double-layer parking space or other similar lifting mechanism has finished rising and is correctly locked on the safety lock, that is, when the stop block 5 is locked on the stop block 4, the weight of the vehicle on the lifting mechanism will press the platform securely onto the safety lock without any additional hydraulic energy, reducing the cost of use. When the power supply is turned off or interrupted or the hydraulic system leaks, the safety lock will remain locked until the control system controller unlocks it. The operation is simple, the overall safety factor is high, and the use effect is good.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
