Description

Straight-bar swing arm type anti-theft intelligent advertisement parking space ground lock

The technical field is as follows:

the utility model relates to an intelligent advertisement parking stall ground lock, specificly relate to a straight-bar swing arm formula theftproof intelligent advertisement parking stall ground lock.

Background art:

with the continuous progress of society, the car has become people's main instrument of riding instead of walk, and the increase of car quantity has directly led to the not enough of parking stall, along with the shortage of supply and demand relation, and the phenomenon of occupying the parking stall by force frequently takes place. In order to solve this problem, the parking stall ground lock on the market has manual parking stall ground lock, remote control parking stall ground lock at present, and the intelligence parking stall ground lock that is comparatively popular up to now, though the appearance is different, but has a lot of common commonality, for example: when the parking space is occupied forcibly, an alarm sound is given out, so that the parking space is not really kept and the battery is not durable; the swing arm is made of rigid materials and is rigidly connected with the base, so that when a vehicle collides with the ground lock, the two parts both cause large loss; the mechanical structure is complex, so that the transmission is more power-consuming and the processing cost is high; the limitation of a mechanical mechanism causes that a gear of a driving motor is easy to damage; no billboard benefit, etc.

Utility model patent of application number 20150563189.X provides an anti remote control parking stall lock that hits of pull rod formula, including the crank bracket, articulated crank mechanism, articulated pull rod and rocking arm top are articulated in proper order, and motor drive crank mechanism, and then drive the pull rod drive rocking arm and close and open the parking stall.

The drawback of the above utility model patent lies in: 1. due to the limitation of a mechanical structure, the motor consumes more power during operation, and the speed reducer is easy to gear; 2. the main transmission part is exposed and easy to rust or be influenced by natural environment, so that the main transmission part cannot be normally used; 3. the rocker arm is rigidly connected with the ground lock body, when a vehicle collides with the ground lock, the vehicle and the ground lock are inevitably damaged, and particularly, the ground lock is extremely difficult to repair and even scrapped integrally and is difficult to deal with various problems during parking; 4. through some common tools and conventional means, the lock can be easily unlocked and even picked without violence on the premise of not opening the outermost protective shell; 5. there is no advertising benefit. And is therefore not the best solution.

The utility model has the following contents:

the utility model aims to solve the technical problem that, to the not enough of above-mentioned prior art, and provide a straight-bar swing arm formula theftproof intelligent advertisement parking stall ground lock.

The utility model adopts the technical proposal that:

a straight-bar swing-arm type anti-theft intelligent advertisement parking space ground lock is characterized in that a transmission support is fixed on a base, a transmission shaft is mounted on the transmission support, an output shaft of a motor is connected with the transmission shaft, a main swing arm is sleeved on the transmission shaft, a cam mechanism is also fixedly connected onto the transmission shaft, the cam mechanism comprises a cam and a swing pin fixed on the cam, and the swing pin is in contact transmission with the main swing arm; the lower part of the transmission support is provided with a bayonet lock sliding groove, a bayonet lock which is in sliding fit with the cam is sleeved in the bayonet lock sliding groove, the end of the bayonet lock is fixedly connected with one end of a tension spring, and the other end of the tension spring is fixedly connected with the transmission support.

Furthermore, a swing pin sliding groove is formed in the main swing arm, the swing pin is sleeved in the swing pin sliding groove, a clamping arm is protruded at the front end of the lower portion of the main swing arm, a bayonet is formed below the clamping arm, and the clamping arm and the bayonet are used for matching and positioning the clamping pin. The bayonet lock is under the effect of cam and extension spring power, through the forward and reverse rotation of cam for the bayonet lock can break away from or get into the bayonet lock, thereby realizes locking when closing the lock in the direction of unblanking.

Furthermore, a swing pin track groove is formed in the transmission support, and the swing pin is sleeved in the swing pin track groove of the transmission support.

Furthermore, an auxiliary support is further fixed on the base, a driven shaft is sleeved on the auxiliary support, an auxiliary swing arm is sleeved on the driven shaft and fixedly connected with the swing frame, and the detector support is located on the swing frame and fixedly connected with the swing frame.

Furthermore, a torsion spring is sleeved on the driven shaft, and force arms at two ends of the torsion spring are respectively clamped on the auxiliary swing arm and the auxiliary support. The torsion spring can store energy under the action of gravity with swing parts such as the straight rod and the advertising board when the lock is unlocked, and release energy when the lock is closed, so that the overturning moment of the motor is reduced, current is reduced, the service lives of the motor and the battery are prolonged, and the overturning process can be more stable.

Furthermore, a main limiting clamping block is arranged at the top of the transmission bracket, and a main limiting clamping groove correspondingly matched with the main limiting clamping block is arranged on the swing frame; the top of the auxiliary bracket is provided with an auxiliary limiting clamping block, and the swing frame is also provided with an auxiliary limiting clamping groove correspondingly matched with the auxiliary limiting clamping block. When the locking is completed, the device can limit the locking in the locking direction.

Furthermore, a detector support is arranged on the swing frame, the lower end of the detector support is fixedly connected with the threading frame, and a detector is arranged on the detector support. The detector detects whether the car is parked on the parking space, and the detector preferably selects an ultrasonic detector. The detector passes through the detector bracket, the swing frame, the threading machine and the driven shaft, so that the influence of wire winding caused by the rotation of the detector can be greatly prevented.
