Being fixedly connected with handle on described cam, the other end of handle is provided with taper knob.
Described fixed mount includes being perpendicular to fixed plate and the first plate arranged in vertical and the second plate, the other end of the first plate and the second plate is provided with the limiting plate of connection, limiting plate is provided with the limited impression matched with handle, described cam and steady pin are arranged in the space that the first plate, the second plate and limiting plate surround, and cam is fixed between the first plate and the second plate by bearing pin.
Being provided with guider between described fixed plate and connecting rod, described guider is two guide posts being fixed in connecting rod, and described fixed plate is provided with the through hole matched with guide post.
Described connecting rod uses channel-section steel to make.
As shown from the above technical solution, this utility model is connected with brake realization linkage by controlling steady pin in device, is driven the translation of steady pin by the rotation of control device cam, to realize the locking of keep plate in brake and tire or to unclamp.This utility model simple in construction, easy to use, highly versatile, it is suitable for all tire model.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
nullSuch as Fig. 1、A kind of parking brake for platform trailer shown in Fig. 2，It is characterized in that: include the fixed plate 1 that vertical is arranged，The side of fixed plate 1 is provided with brake，The opposite side of fixed plate 1 is provided with the control device being connected with brake，Control the steady pin 2 that device includes passing perpendicularly through fixed plate 1 and being connected with brake，Spring 3 it is arranged with on steady pin 2，One end of spring 3 leans with the head of steady pin 2，The other end of spring 3 leans with the plate face of fixed plate 1，Control the cam 4 that device also includes leaning with steady pin 2 head，Cam 4 and steady pin 2 are arranged in fixed mount 5，Fixed mount 5 is provided with the limiting plate 51 limiting cam 4 rotational angle，When cam 4 is clockwise at limiting plate 51，Spring 3 is in compressive state，Cam 4 promotes steady pin 2 and drives the braking of brake realization and tire.
Further, brake includes the connecting rod 7 be arrangeding in parallel with fixed plate 1, connecting rod 7 be respectively arranged at two ends with the keep plate 8 matched with tire, keep plate 8 realizes the on-position held tightly with tire or the non-brake state unclamped with tire under the effect controlling device, the afterbody of steady pin 2 is provided with thread segment, this thread segment through fixed plate 1 and is fixed by nut with connecting rod 7, and the steady pin 2 namely controlled in device fixes with brake with the linkage of both realizations.
Further, cam 4 being fixedly connected with handle 41, the other end of handle 41 is provided with taper knob 42.Cam 4 is fixing connection with handle 41, i.e. can handle cam 4 by operation handle and rotate.
Further, fixed mount 5 includes the first plate 52 and the second plate 53 being perpendicular to fixed plate 1 and arranging in vertical, first plate 52 is provided with the limiting plate 51 both being connected with the other end of the second plate 53, limiting plate 51 is provided with the limited impression 54 matched with handle 41, in the space that cam 4 and steady pin 2 are arranged on first plate the 52, second plate 53 and limiting plate 51 surrounds, cam 4 is fixed between the first plate 52 and the second plate 53 by bearing pin 9, and bearing pin 9 is perpendicular to the first plate 52 and the second plate 53 is arranged.
Further, being provided with guider between fixed plate 1 and connecting rod 7, guider is two guide posts 71 being fixed in connecting rod 7, and fixed plate 1 is provided with the through hole matched with guide post 71.Guide post 71 can play the guiding role during the translation of steady pin 2.
Further, connecting rod 7 uses channel-section steel to make.
Operation principle of the present utility model is as follows:
Manual operation handle 41, it is made to be clockwise in the limited impression of limiting plate, now, handle can not be rotated further, while handle rotates, the cam being connected with handle promotes the steady pin being positioned at fixed mount toward left movement, drives the keep plate in connecting rod therewith toward left movement simultaneously, thus locking tire reaches the purpose of braking；At steady pin toward while left movement, spring on steady pin is in compressive state, owing to cam has auto-lock function, after cam motion puts in place, i.e. realize self-locking, so when need not braking, Manual operation handle is only needed to rotate counterclockwise, i.e. up being carried by handle by the least power, under the self-return effect of spring, keep plate can move right, keep plate unclamps with tire, it is achieved non-brake state.This utility model can regulate stroke by the size of adjustment cam, and the size of keep plate can change with the change of tire size.
Embodiment described above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
