Abstract
The invention discloses a caster with a locking device. The caster comprises a wheel carrier, and a roller which is arranged on the wheel carrier in a way that a screw passes through a shaft hole; a shell which is coaxial with the roller is movably arranged between the wheel carrier and the roller; an elastic mechanism is connected between the shell and the wheel carrier; a protruded hook is arranged on the wheel carrier; and a clamping position corresponding to the protruded hook is formed on the shell. When the caster is used, the protruded hook is embedded into the clamping position and hooks the shell to ensure that the shell does not influence the action of the roller; when the caster is needed to be locked, the shell is ejected under the action of the elastic mechanism by loosening the protruded hook to wrap the caster so as to ensure that the roller cannot rotate, and guarantee the stability of equipment during fixing; and the caster is convenient to operate and the roller is not required to be dissembled and assembled.
Description
Technical field
The present invention relates to a kind of castor, particularly a kind of blocking device caster wheel that has.
Background technology
At present, castor be widely used in people's daily life and commercial production in, all install castor mostly as the hand barrow in desk, chair, the market, the production facilities in the factory building etc., move with convenient.But general caster wheel all is not provided with blocking device, when needs are fixed on a certain position to equipment, has influenced the steadiness of equipment because of the existence of castor, needs the dismounting castor, and is very inconvenient.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of device caster wheel of deciding with lock, can lock castor it can not be moved freely, guaranteed the solid timer-operated stability of equipment.
The technical solution adopted in the present invention is:
A kind of device caster wheel of deciding with lock, comprise wheel carrier, adopt screw to pass axis hole to be installed in roller on the wheel carrier, be movably set with the housing coaxial between described wheel carrier and the roller with roller, be connected with elastic mechanism between described housing and wheel carrier, described wheel carrier is provided with protruding hook, and described housing is provided with the screens of corresponding protruding hook.When castor was in running condition, protruding hook embedded screens and hooks housing, made housing not influence the roller action; When needs locking castor, by unclamping protruding hook housing is ejected under the effect of elastic mechanism, coat roller, roller can not be rotated.
As improvement of the technical scheme, described elastic mechanism is preferably extension spring, 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 protruding hook is connected with the switching device that is used to control, and described switching device can also can be automatic inductive switch for being arranged on the button on the wheel carrier or dialling key.
As improvement of the technical scheme, described wheel carrier upper end is provided with tie bolt, and described tie bolt can be around the axle center rotation.
The invention has the beneficial effects as follows: thisly with lockly decide the device caster wheel and can control housing by switching device and coat roller, the locking roller no longer rotates it, has guaranteed the solid timer-operated stability of equipment, and easy to operate, does not need the dismounting roller.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a part sectional view of the present invention;
Cutaway view when Fig. 2 is of the present invention the locking;
Switching device does not draw among above-mentioned Fig. 1 and Fig. 2.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of device caster wheel of deciding with lock of the present invention, comprise wheel carrier 1, adopt screw to pass axis hole to be installed in roller 2 on the wheel carrier 1, be movably set with the housing 3 coaxial between described wheel carrier 1 and the roller 2 with roller 2,1 of described housing 3 and wheel carrier are connected with extension spring, described extension spring is installed on the screw as the axle center, and described extension spring one end connects wheel carrier, and the other end connects housing; Described wheel carrier 1 is provided with protruding hook 4, and described housing 3 is provided with the screens 31 of corresponding protruding hook.Described protruding hook is connected with the switching device that is used to control, and described switching device can also can be automatic inductive switch for being arranged on the button on the wheel carrier or dialling key.Thisly with lockly decide the device caster wheel owing to adopt said structure, protruding at ordinary times hook 4 is stuck in the screens 31 of housing 3, make housing 3 be fixed on roller 2 tops, during switch motion, can unclamp protruding hook 4, housing 3 ejects under the effect of extension spring, coats roller 2, make roller 2 break away from ground, the locking castor can not move by it.
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 invention, as long as realize that with basic identical means the technical scheme of the object of the invention all belongs within protection scope of the present invention.
