Abstract
The utility model relates to a positioning mechanism for the switching of control handles, which comprises a fixed block and a swing block connected with the fixed block through a rotary shaft, and moreover, a double-arm torsion spring for restoration is arranged on the rotary shaft as well. The utility model is characterized in that positioning and impact resistance are respectively executed by different parts. The fixed block and the swing block of the steel structure are connected together by the rotary shaft to form a hinge structure, which can fully bear the impact brought by manual operation, and because the characteristic of the double-arm torsion spring is strong torsion-bearing capability, the double-arm torsion spring fixed on the rotary shaft just can provide force needed by the restoration of the swing block. The utility model avoids the unnecessary repair of a broken spring sheet and the like caused by the prior art, and enhances the reliability of the control handle products.
Description
Technical field
The utility model relates to a kind of detent mechanism, is specifically related to a kind of bar handle conversion detent mechanism.
Background technology
At present a lot of bar handle class detent mechanisms all adopt fixed idler whell formula structure on the shell fragment, this structure exists vice proper, though be exactly that it has preferably the location (give the cam certain pressure when the handle conversion stops, make it be fixed on current location) function, but the impact capacity of anti-handle switching process is poor, often occur phenomenon of rupture in the application, influenced properties of product and safe in utilization greatly.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of and can improve product life and bar handle class conversion detent mechanism safe in utilization.
For achieving the above object, the technical solution adopted in the utility model is: comprise fixed block and the swinging block that is connected with fixed block by rotating shaft, and also be provided with the both arms torsion spring of reset response in rotating shaft.
Swinging block of the present utility model is installed in the fixed block by rotating shaft, and the both arms torsion spring is installed in the outside of fixed block; Also be provided with limiting gasket in the rotating shaft in the both arms torsion spring outside; The leading section of swinging block also is provided with a roller that is used to locate.
The utility model is divided into two former location and shock resistance function.The location is carried out by different parts respectively with shock resistance.The fixed block of steel structure and swinging block are by the rotation connection structure that is connected to become of rotating shaft, and it can bear the impact that artificial manipulation brings fully, and the characteristic of both arms torsion spring is that to bear torsion capacity strong, and it is fixed on the swinging block required power that resets just in time is provided in the rotating shaft.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present utility model, fixed block 1, swinging block 2, both arms torsion spring 3, rotating shaft 4, roller 5, rivet shaft 6, packing ring 8 among the figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1, the utility model comprises fixed block 1 and is installed in swinging block 2 in the fixed block 1 by rotating shaft 4, and also be provided with the both arms torsion spring 3 of reset response in the outside that rotating shaft 4 is positioned at fixed block, in order to prevent that both arms torsion spring and swinging block break away from rotating shaft, the utility model also is provided with limiting gasket 8 in the rotating shaft 4 in both arms torsion spring 3 outsides, leading section at swinging block 2 also is provided with a roller that is used to locate 5, and this roller 5 is installed on the swinging block 2 by rivet shaft 6.
In order further can clearly to describe working process of the present utility model, the utility model is installed on the driver controller: during use fixed block 1 is fixed on the driver controller, pull the driver controller handle, thereby drive swinging block 2 rises and falls along with the driver controller cam and swings, at this moment, the roller 5 that is positioned at swinging block 2 ends under the effect of both arms torsion spring 3 runback power matches with the groove of cam, plays positioning action.Because the utility model is divided into two former location and shock resistance function, location and shock resistance are carried out by different parts respectively, and it is long therefore to the utlity model has the life-span, and installation and maintenance make things convenient for, characteristics such as reliability height, and the normal conversion that does not influence the bar handle series products is used.
