Abstract
The utility model discloses an inductive self-locking trundle, which comprises a carrier and a trundle mounted on the carrier by means of a screw penetrating through a shaft hole. An inductive transmitter and a receiver are arranged at the front end of the carrier and connected with a locking mechanism which is used for locking the trundle and arranged on the carrier. A signal transmitted by the inductive transmitter can return to the receiver when running into a set obstacle, and received and processed by the receiver to transmit a control signal for controlling the locking mechanism in motion, so that the trundle is locked and cannot move. The inductive self-locking trundle is applicable to burglary prevention of trolleys in shopping malls and equipment management of factories.
Description
Technical field
The utility model relates to a kind of castor, particularly a kind of induction self-locking castor that is used for market hand barrow and factory equipment.
Background technology
People's shopping for convenience, supermarket and market all provide hand barrow to use when doing shopping to client, but, some client just unloads commodity on the hand barrow can releasing the market to hand barrow after the shopping, the hand barrow of sky is not pushed back the market then yet, cause losing of hand barrow easily like this, also be not easy to the management of commercial rival go-cart simultaneously.In factory building, some need roving equipment that the convenient roller devices that moves is installed usually, but occur the workman easily the situation of equipment release factory building, are not easy to the management of equipment.
The utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of self-locking castor that has induction installation.
The technical scheme that the utility model adopted is:
A kind of induction self-locking castor, comprise wheel carrier, adopt screw to pass axis hole to be installed in roller on the wheel carrier, described wheel carrier front end is provided with inductive activity and receptor, and described inductive activity and receptor are connected with and are arranged on the lockout mechanism that being used on the wheel carrier locks roller.The signal that sends when inductive activity runs into the obstacle of setting, can the reflected back receptor, accept processing by receptor, and send control signal, control locking mechanism action, locking roller.
As improvement of the technical scheme, described inductive activity and receptor preferably adopt infrared pickoff, and inductive activity and receptor can also adopt ultrasonic transduter.
As improvement of the technical scheme, described inductive activity and receptor are connected with the protruding hook that is used to control the locking mechanism action.
As improvement of the technical scheme, described lockout mechanism comprises and is installed on the wheel carrier with the housing of roller coaxial rotation, is connected the elastic mechanism of housing and wheel carrier.
As improvement of the technical scheme, described elastic mechanism is preferably the extension spring that is arranged on the housing both sides, and described extension spring is installed on the screw as the axle center, and described extension spring one end connects wheel carrier, and the other end connects housing.
As improvement of the technical scheme, described housing is provided with the screens of corresponding protruding hook.
As improvement of the technical scheme, described wheel carrier upper end is provided with the tie bolt around the axle center rotation.
The beneficial effects of the utility model are: this induction self-locking castor adopts infrared pickoff to transmit and receive infrared signal, when infrared signal run into the obstacle that is arranged on places such as outlet reflect back be received processing after, inductor unclamps the protruding hook that hooks housing, under the effect of extension spring, housing ejects and coats roller, and it can not be rotated, and plays the purpose of self-locking, locking by pair roller reaches the effect that equipment can not be taken particular place out of, can be used for antitheft and facility management.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a part sectional view of the present utility model;
Fig. 2 is the cutaway view of the utility model when lock-out state.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of induction self-locking castor of the present utility model, comprise wheel carrier 1, adopt screw to pass axis hole and be installed in roller 2 on the wheel carrier 1, described wheel carrier 1 front end is provided with infrared pickoff 5,2 on described wheel carrier 1 and roller are equipped with the housing 3 with roller 2 coaxial rotation, 1 of described housing 3 and wheel carrier are connected with extension spring, described extension spring is installed on the screw as the axle center, described extension spring one end connects wheel carrier 1, the other end connects housing 3, and housing 3 is provided with screens 31, and infrared pickoff 5 is connected with protruding hook 4, protruding hook 4 is stuck in the screens 31, and protruding hook 4 is moved by infrared pickoff 5 controls.This induction self-locking castor adopts infrared pickoff 5 to transmit and receive infrared signal, when infrared signal run into the obstacle that is arranged on places such as outlet reflect back be received processing after, inductor unclamps the protruding hook 4 that hooks housing 3, under the effect of extension spring, housing 3 ejects and coats roller 2, and it can not be rotated, and plays the purpose of self-locking, locking by pair roller 2 reaches the effect that equipment can not be taken particular place out of, can be used for antitheft and facility management.
Further, described wheel carrier 1 upper end is provided with tie bolt 10, and tie bolt 10 can be around the axle center rotation, after castor is installed on the equipment by tie bolt 10, can turn to all directions to move.
The above only is a preferential embodiment of the present utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the present utility model.
