Description
Technical field
This utility model relates to the seat belt technical field, is specifically related to a kind of electronics locking wheelchair safety belt.
Background technology
Seat belt blocks or is wrapped on the human body as its name suggests, is used for guaranteeing that human body when meeting accident action, avoids being subjected to the banded utensil of great bodily injury.The seat belt that we see usually is divided into and is installed in the safety belt for vehicle that tiltedly is pulled in human body the place ahead on the car seat; And the work high above the ground personnel mainly use the special-purpose fall arrest seat belt at waist.Seat belt also uses on some special personage's healths or on its using appliance through regular meeting, can not oneself walk as some legs and feet deformity of picture, and seat belt usually just often is installed on the wheelchair of riding instead of walk of Shi Yonging.Be used for fixing when human body prevents its descending or deceleration and from the wheelchair drop.
But we are commonly used to fixedly disability passenger's wheelchair and are to use hand-adjusting type device and the self-locking device of crispaturaing of crispaturaing, wherein the hand-adjusting type device of crispaturaing is to need the user manual operation to open the lockable mechanism of the device of crispaturaing, to obtain the required ribbon amount of pulling out, when shut-down operation, locking automatically; The self-locking device of crispaturaing is freely to pull out ribbon by Len req, and when hook or bracelet fastening, can adjust ribbon length and the locking device of crispaturaing automatically according to the bodily form of user, if user is not had a mind to release, ribbon will can further not pulled out.These the two kinds devices of crispaturaing use inconvenience for the disability passenger, need others to assist and could use, and when others assists to use fixedly wheelchair, four wheelchair safety belts be tightened evenly that fixedly wheelchair is more time-consuming.
Summary of the invention
At above problem, this utility model provides a kind of electronics locking wheelchair safety belt that makes things convenient for the disability personnel operation.
The technical scheme that its technical problem that solves this utility model adopts is: this electronics locking wheelchair safety belt comprises housing, the device of crispaturaing, electronic lock structure, ribbon, union joint, hook; Described device and the electronic lock structure of crispaturaing is loaded on the described housing, and described ribbon one end links to each other with the described device of crispaturaing, and is connected with wheelchair behind the end sewing hook, and described union joint is connected with two power lines and adopts buckle structures to link to each other with automobile power source; Described electronic lock structure comprises buckle fork, plastic cement skeleton, coil, extension spring, electromagnetic system moving plate, plastic cement gear; Described coil is wrapped on the plastic cement skeleton, and described plastic cement gear links to each other with the device of crispaturaing, and described coil is controlled described electromagnetic system moving plate by electromagnetic force, and described buckle fork one end is hinged on the housing, and an end links to each other with described electromagnetic system moving plate; Described buckle fork is realized and the contacting or disconnection of described plastic cement gear by swing.
This electronics locking wheelchair safety belt is under the energising situation, and the electromagnetic system moving plate is drawn onto on the plastic cement skeleton limit by the action of a magnetic field, drives the buckle fork and moves release, and under this state, ribbon can be pulled out adjustment length; Coil is under powering-off state, and magnetic field disappears, and the electromagnetic system moving plate is under the effect of extension spring, revert to original position, drive the buckle fork and move to the right, contact with the plastic cement gear, ribbon can't be pulled out again, and ribbon can only be in the device of crispaturaing under the strength effect of wind spring, automatically retraction.
As preferably, described electromagnetic system moving plate uses the SPCC material, and its surface uses trivalent chromium environmental protection zinc to electroplate.
The beneficial effects of the utility model are: the utensil of crispaturaing in this electronics locking wheelchair safety belt has adjustment state and automatic retracted mode, and it can determine the state of the described device of crispaturaing by the control to power supply, thereby makes things convenient for disabled's regulation and control.

Fig. 2 is the internal structure sketch map of electronic lock structure under the energising situation.
Fig. 3 is the internal structure sketch map of electronic lock structure under cold situation.
The specific embodiment
Further specify below in conjunction with this utility model of embodiment:
Shown in embodiment among Fig. 1, this electronics locking wheelchair safety belt, it comprises housing 1, the device 2 of crispaturaing, electronic lock structure 3, ribbon 4, union joint 5, hook 6; The described device 2 of crispaturaing is loaded on the described housing 1 with electronic lock structure 3, and described ribbon 4 one ends link to each other with the described device 2 of crispaturaing, and an end sewing hook 6 backs are connected with wheelchair, and described union joint 5 is connected with two power lines and adopts buckle structure to link to each other with automobile power source.
As shown in Figures 2 and 3, described electronic lock 3 structures comprise buckle fork 31, plastic cement skeleton 32, coil 33, extension spring 34, electromagnetic system moving plate 35, plastic cement gear 36; Described coil 33 is wrapped on the plastic cement skeleton 32, described plastic cement gear 36 links to each other with the described device 2 of crispaturaing, described coil 33 is controlled described electromagnetic system moving plate 35 by electromagnetic force, and described buckle fork 31 1 ends are hinged on the housing 1, and an end links to each other with described electromagnetic system moving plate 35; Described buckle fork 31 is realized and the contacting or disconnection of described plastic cement gear 36 by swing.
This electronics locking wheelchair safety belt mainly is fixed on the wheelchair, in use, described ribbon 4 is pulled out by hook 6 from the device 2 of crispaturaing and is connected with wheelchair, by fixing wheelchair, in conjunction with the personal harness system disabled's health is limited on the wheelchair, prevent wheelchair motion when driving, prevent that in conjunction with the personal harness system disabled from from the wheelchair dropping.
