[0002] At present, in the car-carrying plate stereoscopic garage, a car-carrying plate is arranged on the steel structure frame of each parking space, and the car-carrying plate usually slides on the parking space, especially in the hook-pull type car-carrying plate stereoscopic garage, when the vehicle is stored or retrieved, after the transport trolley reaches the layer where the vehicle is stored or retrieved, the leveling positioning mechanism arranged on the transport trolley will be actuated first, and the leveling positioning arm will be extended to realize the leveling positioning of the transport trolley, and then the car-carrying plate will be stored or retrieved. When the car-carrying plate is parked on the steel structure frame, it is usually necessary to lock and position it on the steel structure frame to prevent the car-carrying plate from sliding off. The existing locking and positioning mechanism usually uses a mechanical locking element, and the driving component drives the wedge block to open the locking element. Since the wedge block needs to be unlocked within a certain stroke, the installation accuracy and manufacturing accuracy of the wedge block are required to be high. Once the error is too large, the locking element cannot be unlocked, affecting the normal operation of the garage.

[0003] Therefore, in the field of stereo garage technology, there is still a need for research and improvement of the vehicle loading plate locking device, which is also a research hotspot and focus in the field of stereo garage technology, and is also the starting point for the completion of the present utility model.

[0005] To solve the above technical problems, the technical solution of the utility model is: a vehicle loading plate locking device, comprising a positioning stop tube fixedly installed on the vehicle loading plate, a locking seat fixedly installed on the berth frame, a swing arm rotatably installed on the locking seat through a first hinge shaft, one end of the swing arm is provided with a locking portion adapted to the positioning stop tube, a push rod is slidably installed on the locking seat, the sliding direction of the push rod is perpendicular to the axial direction of the first hinge shaft, a connecting block is installed on the push rod, the connecting block is hinged to a connecting rod through a second hinge shaft, the connecting rod is hinged to the swing arm through a third hinge shaft, the axes of the first hinge shaft, the second hinge shaft and the third hinge shaft are all arranged in parallel, and when the vehicle loading plate is in a locked state, a line connecting the centers of the second hinge shaft and the third hinge shaft is perpendicular to the sliding direction of the push rod.

[0006] As an improvement, a return spring is provided between the connecting block and the locking seat, the return spring is a compression spring, and the return spring is sleeved on the push rod.

[0007] As a further improvement, the push rod is provided with a threaded section, and the connecting block is threadedly connected to the threaded section.

[0008] As a further improvement, a locking nut is threadedly connected to the threaded section, the locking nut abuts against the connecting block, and the locking nut is located on a side away from the reset spring.

DETAILED DESCRIPTION

[0019] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments.

[0021] like Figure 1 and Figure 2As shown, a vehicle loading plate locking device comprises a positioning stop tube 2 fixedly mounted on the vehicle loading plate 1, the positioning stop tube 2 is usually a square tube welded to the bottom of the vehicle loading plate 1, a locking seat 3 is fixedly mounted on the berth frame, a swing arm 4 is rotatably mounted on the locking seat 3 through a first hinge shaft 5, one end of the swing arm 4 is provided with a locking portion adapted to the positioning stop tube 2, usually the locking portion is a card slot structure, the card slot is stuck on the positioning stop tube 2 in a locked state, and the card slot is detached from the positioning stop tube 2 in an unlocked state, a push rod 6 is slidably mounted on the locking seat 3, and the sliding direction of the push rod 6 is perpendicular to the axial direction of the first hinge shaft 5. In order to ensure the smooth sliding of the push rod 6, two spaced support arms 301 are usually welded on the locking seat 3, and the push rod 6 passes through the two support arms 301, so that The push rod 6 forms a supporting beam structure with two points of support, and a connecting block 7 is installed on the push rod 6. The connecting block 7 is located between the two supporting arms 301, and the connecting block 7 is hinged to the connecting rod 9 through the second hinge shaft 8, and the connecting rod 9 is hinged to the swing arm 4 through the third hinge shaft 10. The axes of the first hinge shaft 5, the second hinge shaft 8 and the third hinge shaft 10 are all arranged in parallel. When an external force drives the push rod 6, the connecting block 7 can translate with the push rod 6, driving the connecting rod 9 to deviate by an angle, thereby driving the swing arm 4 to swing. When the carrier plate 1 is in a locked state, the line connecting the centers of the second hinge shaft 8 and the third hinge shaft 10 is perpendicular to the sliding direction of the push rod 6, and the locking force acts on the locking seat 3. In the absence of external force, the locking is firm, thereby improving the safety performance of the utility model.

[0022] A return spring 11 is provided between the connecting block 7 and the locking seat 3. The return spring 11 is a compression spring. The return spring 11 is sleeved on the push rod 6. Usually, one end of the compression spring rests on the locking block, and the other end rests on the support arm 301 of the locking seat 3 away from the locking block. The return spring 11 is compressed when unlocking. After unlocking, it can be reset under the action of the spring force to achieve locking of the vehicle loading plate 1, which is convenient to operate.

[0023] The push rod 6 is provided with a threaded section 601, and the connecting block 7 is threadedly connected to the threaded section 601, and the initial position of the connecting block 7 on the push rod 6 can be adjusted so that in the locked state, the line connecting the centers of the second hinge shaft 8 and the third hinge shaft 10 is perpendicular to the sliding direction of the push rod 6. In order to ensure that the position of the connecting block 7 on the push rod 6 is fixed, the threaded section 601 is threadedly connected to a locking nut 12, and the locking nut 12 abuts against the connecting block 7, and the locking nut 12 is located on the side away from the reset spring 11.

[0024] When using, Figure 3 As shown, when the push rod 6 is driven by an external force, the connecting block 7 can translate with the push rod 6, driving the connecting rod 9 to deviate by an angle, thereby driving the swing arm 4 to swing, so that the vehicle loading plate 1 is unlocked; after the external force is eliminated, under the action of the spring force, the push rod 6 is reset to achieve the locking of the vehicle loading plate 1.

[0025] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
