Description

free shifter

technical field

The invention relates to a tool for moving vehicles, in particular to a vehicle shifter for moving and parking various cars that are not suitable for parking.

Background technique

Now with the continuous increase of car ownership, the parking lot is becoming more and more tense, and the parking space of vehicles is getting smaller and smaller. Coupled with irregular parking, some vehicles cannot enter and exit. In order to realize the normal entry and exit of these vehicles, other The vehicle moves in a small range, and when the car is parked, the driving wheel is in a braking state, and the friction between the wheel and the ground is very large. It is impossible to move the vehicle only by manpower without the help of other equipment. Only the driver can be found to move the vehicle. In order to solve this problem, the data and patent documents were consulted, and only one utility model Chinese patent "universal vehicle shifter" was found. Publication (announcement) number: CN2543740, publication (announcement) date: 2003.04.09. This patent can solve the above problems, but it uses the engagement of pawls and ratchet bars to realize the movement between the fixed frame and the movable frame, and there is a limited moving distance between the fixed frame and the movable frame, so it is difficult to lift the wheels off the ground or off the Disadvantage of small ground distance. In addition, the pawl and the ratchet strip cannot realize self-locking, and the pedal is hooked by the hook for self-locking, which requires the pedal to deflect at an angle, which is difficult to achieve.

Contents of the invention

The invention provides a vehicle moving device with simple operation, labor saving and low cost, which can move the vehicle freely within a short distance to facilitate the access of the vehicle, save the parking space and increase the number of vehicles parked.

The components of the car shifter provided by the present invention include universal wheels, rack jackets, assembled racks, left brackets, gears, sleeves, bracket shafts, right brackets, push hooks, self-locking blocks, and handles. The gear is installed on the rack cover, the handle drives the push hook to drive the gear to rotate, the gear meshes with the assembled rack, the self-locking block to prevent the gear from reversing is installed on the rack cover, and the two left brackets are connected by a bracket shaft. Two right supports are connected with a support shaft, and universal wheels are all arranged below the left support and the right support. The assembled rack is fixedly connected with a left bracket, the rack overcoat is fixedly connected with a right bracket, and sleeves are arranged on the shafts of the left and right brackets.

Pull the handle, turn the gear, and realize the relative movement between the assembled rack and the rack jacket. In order to prevent the gear from reversing, a self-locking block is set. In order to reduce the friction during relative motion, a rolling bearing is arranged between the assembled rack and the rack jacket to convert sliding friction into rolling friction. The rack and the jacket drive the two supports to move relative to each other and reduce the distance between them, thereby achieving the purpose of lifting the wheels off the ground. After all four wheels are lifted off the ground, a person can push the vehicle to move it.

The outstanding advantages of the car shifter provided by the present invention are: it does not use electric power, is light, and saves manpower; the relative movement of the two brackets is realized by using the engagement between the gear and the rack, which not only transmits large force, but also can Prevent the reversal of the gear, so that the gear will not reverse when the handle is pulled back and forth, so that the relative movement distance between the gear and the assembled rack can be increased, thereby increasing the height of the wheel from the ground. The car mover can move the car freely within a short distance, which is convenient for the access of the car. At the same time, the space for parking can be saved and the number of parking lots can be increased.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, the components of the car shifter provided by the present invention include a universal wheel 1, a rack outer cover 2, an assembled rack 3, a left bracket 4, a gear 5, a sleeve 6, Support shaft 7, right support 8, push hook 9, self-locking block 10, handle 11. The gear 5 is installed on the rack overcoat 2, the handle 11 drives the push hook 9 to drive the gear 5 to rotate, the gear 5 meshes with the assembled rack 3, and the self-locking block 10 preventing the gear from reversing is installed on the rack overcoat. Support 4 is connected with a support shaft 7, and two right supports are connected with another support shaft 7, and universal wheels are all arranged below the left support and the right support. Assembled rack 3 is fixedly connected together with a left support, and rack overcoat 2 is fixedly connected together with a right support, and sleeve 6 is housed on the axle of left and right supports.

In order to reduce the friction during relative motion, a rolling bearing is arranged between the assembled rack 3 and the rack outer case 2 to convert sliding friction into rolling friction.

When moving the vehicle, place a car mover under each wheel, move the handle 11 forward, the handle transmits force to the gear 5 through the push hook 9 to make it rotate, and the gear 5 meshes with the assembled rack 3, so that Assembled rack 3 makes relative movement with respect to jacket 2. In order to prevent the gear from reversing, a self-locking block 10 is provided. Universal wheels 1 are arranged below the left bracket 4 and the right bracket 8 . The assembled rack 3 is fixedly connected with the left bracket 4, and the overcoat 2 is fixedly connected with the right bracket 8. When the assembled rack 3 moves relative to the jacket 2, it will drive the two brackets to move relative to each other and reduce the distance between them, thereby realizing the purpose of lifting the wheel off the ground. In order to reduce the friction between the axle and the tire, a sleeve 6 is installed on the axle 7 of the left and right supports. After all four wheels are lifted off the ground, a person can push the vehicle to move it.

When it is necessary to remove the car shifter, press the handle 11 backward, and the handle 11 will press the self-locking block 10 up. At this time, the self-locking function is canceled, and the left and right brackets move in the opposite direction under the action of gravity, and the gear 5 is in the assembly mode. Reverse rotation on the rack 3 increases the distance between the two supports, the tires of the car move down and land on the ground, and the car shifter is unloaded to complete the car shifting process.
