Description
Technical field
The utility model relates to a kind of locking device, is specifically related to a kind of elasticity locking device for locking material door.
Background technology
At present, locking device is all widely used in all trades and professions, but elasticity is not with in the locking device inside of routine, and tightening force during work can not regulate automatically.Conventional locking device is when working environment is comparatively complicated, very easily occur getting loose when particularly the duty of equipment is in rotation or vibrational state, such as be in the locking device etc. of the seed dresser barrel door of rotation status, locking device easily gets loose thus brings hidden danger to safety in production.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of material door snap lock to close device, and in its course of work, tightening force can Automatic adjusument, reasonable in design, structure is simple, easy to operate, applied widely, cost of production is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of material door snap lock closes device, comprise side to be rotatably installed on material bin and lateral wall with the door of columnar projections, it is characterized in that: also comprise T-shaped handle for locking described door and for providing the driving spring of driving force for described T-shaped handle; Described material bin lateral wall is fixedly installed mount pad, described mount pad is rotatablely equipped with U-shaped by bearing pin help pull a cart, described U-shaped sidewall of helping pull a cart is provided with T-shaped pull bar by symmetrically arranged slide, described T-shaped pull bar and described U-shaped are provided with described driving spring between helping pull a cart, described T-shaped pull bar lower end is installed with described T-shaped handle, and described T-shaped handle middle part is provided with the padlock hole of matching with described columnar projections.
Above-mentioned material door snap lock closes device, it is characterized in that: described mount pad is welded on described material bin lateral wall.
Above-mentioned material door snap lock closes device, it is characterized in that: described mount pad is fixedly mounted on described material bin lateral wall by screw.
Above-mentioned material door snap lock closes device, it is characterized in that: described T-shaped pull bar lower end is welded on described T-shaped handle.
Above-mentioned material door snap lock closes device, it is characterized in that: described T-shaped pull bar lower end shakes hands to be fixedly connected with by screw thread and described T-shaped.
The utility model compared with prior art has the following advantages:
(1) this material door snap lock close the T-shaped pull bar of device and U-shaped help pull a cart between be provided with back-moving spring, therefore its tightening force can Automatic adjusument in the course of the work.
(2) this material door snap lock closes apparatus design very rationally, simple and compact for structure, and operating personnel only need pull T-shaped to shake hands to complete locking and unlock operation, and operation is very easy.
(3) this material door snap lock closes the locking that device is not only applicable to material bin door, and be also applicable to the field that other needs locking, the scope of application widely.
(4) this material door snap lock closes device production technology simply, and requirement on machining accuracy is not high, and a lot of parts are convenient to produce or buy all very much, and thus its cost of production is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.
