The brake structure of portable digital X ray camera
Technical field
This utility model relates to a kind of brake structure, particularly relates to a kind of brake structure of portable digital X ray camera.
Background technology
Usually, portable mobile X ray camera is equipped with roller, can promote non-special-purpose health check-up places such as this portable mobile X ray camera is other, outdoor to hospital bed, family, so that seriously ill patient checks on the spot.Yet, in case after being pushed into above-mentioned non-special-purpose health check-up place, if there is external force collision just can make it arbitrarily mobile, what be unfavorable for checking normally carries out.Therefore, need brake gear to be installed, keep resting state in the time of can making portable mobile X ray camera stop to advance really at the roller place.
Yet existing brake gear is locked or during release, all need be bent over to pull brake handle with hands in each brake, and operation is inconvenience very.
The utility model content
This utility model proposes to have laborsaving, safe and reliable foot-operated brake structure in a kind of portable digital X ray camera, to solve the existing unhandy technical problem of brake gear.
This utility model adopts following technical scheme to realize: a kind of brake structure of portable digital X ray camera, and it comprises: the two ends through connecting axle fix the foot-operated assembly on vehicle frame with rotation mode; Intert rotating shaft on vehicle frame and the brake assemblies that is installed on said rotating shaft terminal; Be connected the connecting axle of said foot-operated assembly and the connecting rod between the said rotating shaft.
Wherein, said brake assemblies comprises: lock respectively at a plurality of swinging blocks of said rotating shaft terminal; Be screwed on a plurality of brake shoes on each swinging block.
Wherein, between the two ends and vehicle frame of said connecting axle, between the two ends of said rotating shaft and the vehicle frame pad is set all.
Wherein, said foot-operated assembly also comprises the pedal that is connected on the said connecting axle.
Wherein, be provided for the block that prevents that said rotating shaft from coming off from said vehicle frame on the two ends of said rotating shaft respectively.
Compared with prior art, the utlity model has following beneficial effect: the brake shoes of using foot-operated assembly to drive brake assemblies moves and is pressed on two wheels of go-cart, can make this go-cart keep resting state; When need promote this go-cart, need trample this foot-operated assembly in the other direction, make two wheels of brake shoes away from go-cart.This foot-operated brake gear is not only laborsaving but also safe and reliable, and simple in structure, with low cost.
Description of drawings
Fig. 1 is that this utility model is installed in the partial structurtes sketch map in the go-cart.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of foot-operated brake gear.
The specific embodiment
In conjunction with the accompanying drawing and the specific embodiment, the agitator of this utility model is done further description:
See also Fig. 1 to Fig. 3, this utility model proposes a kind of foot-operated brake gear, and it comprises: foot-operated assembly, and in order to apply active force on it, it has pedal 21 and connecting axle 22, and the rotatable mode in the two ends of this connecting axle 22 fixes on vehicle frame 11; Brake gear, in order to stop the rolling of wheel 12, it has rotating shaft 23 and brake assemblies 24, and intert on vehicle frame 11 at the two ends of this rotating shaft 23, and said brake assemblies 24 is installed on the two ends of said rotating shaft 23; And connecting rod 25, this connecting rod 25 pivotally is connected with the connecting axle 22 of above-mentioned foot-operated assembly and the rotating shaft 23 of above-mentioned brake gear respectively.Wherein, said brake assemblies 24 comprises: swinging block 241, through the two ends of screw locking in said rotating shaft 23; Brake shoes 242 is fastened on the said swinging block 241 through screw thread; And place, the two ends of said rotating shaft 23 also is provided with and prevents that this rotating shaft 23 is by the block that comes off on the vehicle frame 11 231.
More excellent, the two ends of said connecting axle 22 and said rotating shaft 23 are provided with the pad (figure does not show) that can increase frictional force between itself and the vehicle frame 11.
After the go-cart that portable mobile X ray camera is installed is pushed into the health check-up place, only need on said pedal 21, to apply active force, said brake shoes 242 is driven to be pressed on two wheels 12 of go-cart, can make this go-cart keep resting state; When need promote this go-cart, need trample said pedal 21 in the other direction, brake shoes is got final product away from two wheels 12 of go-cart.
The above is merely the preferred embodiment of this utility model; Not in order to restriction this utility model; Any modification of being done within all spirit and principles at this utility model, be equal to replacement and improvement etc., all should be included within the protection domain of this utility model.
