Description

Parking spot lock

Technical Field

The utility model relates to parking space management equipment, in particular to a parking space lock.

Background

In recent years, parking difficulties have become increasingly a social problem, especially in densely populated cities. Therefore, the parking spot lock has been widely used as a parking spot management and control device. The mechanical parking spot lock and the electric lifting parking spot lock which are common in the prior art and provided with suggestions are more convenient to use, the electric lifting parking spot lock can control the lifting of the parking spot lock in a remote control mode, the parking spot lock does not need to be driven off for operation, but the mechanical parking spot lock is expensive in price and complex in installation, so that the mechanical parking spot lock still is the primary choice of most consumers. The rapidness and convenience of unlocking and locking the mechanical parking spot lock are important factors for consumers to select the mechanical parking spot lock.

The utility model patent with application number 201410162718.0 discloses a gantry parking space lock, which comprises two bases, a gantry main body and a lock cylinder, wherein the lower ends of two support arms of the gantry main body are respectively hinged with the two bases, and the gantry parking space lock is characterized in that: at least one support arm of the gantry main body is in a hollow tubular shape, a lock cylinder mounting hole is arranged on the tube wall of the hollow tubular support arm, the lock core is arranged on the hollow tubular support arm through the lock core mounting hole, the main body of the lock core is arranged in the hollow tubular support arm, the lock hole end of the lock core faces the outer side of the hollow tubular support arm, the rear end of the lock core main body is connected with a locking piece which is connected with a transmission piece, the other end of the transmission piece is connected with a locking pin which is arranged in the hollow tubular support arm and can drive the locking pin to move, the pipe wall of the hollow tubular support arm is provided with a through hole for the locking pin to extend out of the pipe wall of the hollow tubular support arm, the base hinged with the hollow tubular support arm is provided with a locking hole, when the gantry main body is lifted, the through hole is opposite to the locking hole, the locking pin extends into the locking hole or retracts into the hollow tubular support arm to lock or unlock the gantry main body. The locking plate comprises a connecting end extending out from the outer side of the lock cylinder body along the radial direction of the lock cylinder body, and the transmission piece is connected with the connecting end, so that when the transmission piece drives the locking pin to move, the movement stroke of the locking pin is increased.

The transmission part is a connecting rod, one end of the connecting rod is connected with the connecting end and is arranged along the length direction of the hollow tubular support arm, a connecting piece hinged with the locking pin is arranged at the end part of the locking pin, the connecting piece is connected with the other end of the connecting rod, and the locking pin is arranged along the radial direction of the hollow tubular support arm so as to convert the rotation of the lock cylinder into the radial sliding of the locking pin along the hollow tubular support arm.

According to the technical scheme disclosed by the utility model, when the gantry main body needs to be lifted and locked again after being laid down, a key is not needed, the locking pin can be automatically locked, and the convenience of operation of the gantry parking space lock is greatly improved.

However, products are rarely sold on the market, and the applicant finds that the technical scheme is very retarded when unlocking in actual use and usually needs to forcibly rotate the lock cylinder. The applicant has found that the transmission structure of the technical solution is the main cause of retardation. According to the technical scheme disclosed by the patent specification of the utility model, the lock core rotates, the connecting rod is pulled to move upwards, the connecting rod lifts one corner at the far end of the top of the connecting piece, and the other corner at the top of the connecting piece is used as a supporting point and is positioned on the supporting plate of the locking pin, so that the bottom of the connecting piece can rotate by taking the supporting point as a circle center, and the locking pin is driven to slide along the radial direction of the hollow tubular supporting arm.

In practical applications, however, the direction of movement of the connecting rod is not a linear movement in its own direction, but rather a movement in the sector area formed when the lock cylinder is rotated; secondly, after the acting force of the rotation of the connecting piece on the locking pin is decomposed, the acting force is not only the pulling force along the axis direction of the locking pin, but also upward pulling force, and the upward pulling force causes the friction force between the locking pin and the supporting arm and the supporting plate.

If the materials of the locking pin and the supporting plate are only common steel, the contact friction force between the locking pin and the supporting plate is larger, so that the convenience degree of the product manufactured by the technical scheme is greatly reduced during unlocking, and the unlocking process is retarded, so that the technical scheme cannot be accepted by the market when being converted into the product.
