Description
Technical field
The utility model relates to a kind of lock on High-low voltage switch cabinet door, particularly four-point supporting locking mechanism.
Background technology
Along with China's reform and opening-up and the continuous speed-raising of economic construction, the electric fixtures used in the fields such as various places industrial and mining enterprises, community, building site, municipal administration is more and more, and safety requirements is also more and more higher.And the shell protection grade of electric fixtures is one of key factor guaranteeing people's life and property safety, only ensure that the shell protection grade of electric fixtures, just have operation and the using function of electric product.All low-voltage complete products all need, by CCC certification ability production and selling, just describing each parameter of product all quite important in China.
Current high and low pressure assembled electric product bin door locking Design and manufacture both domestic and external mostly is two kinds below:
1. cabinet door, degree of protection requirement after producing deformation without the monolateral single-point of door lock, monolateral upper and lower 2 or monolateral 3 locking design methods guarantee door-plates in processing or transport process, easily there is the upper and lower tilting of door-plate or left and right out-of-flatness phenomenon, more cannot ensure that hinge side is consistent with the degree of protection of door lock side, the shell protection class requirement that the standard that cannot ensure is clear and definite;
2. cabinet door lock is that bolt type connects the Design and manufacture method of locking to hole, the method can only solve the processing problems that door-plate tilts up and down substantially, but because the process of locking hole requires very high, after carrying transfer and in-site installation, this series products often cannot realize hole locking function, even also there is the phenomenon that cannot lock a door, occur potential safety hazard on the contrary.
Because present stage low-voltage complete electric product is a lot, also different to the attention degree of degree of protection, product door lock locking technique, technology is obviously not enough, can not meet the needs of modern electrical product to security protection.
Therefore in order to solve the problem, the utility model provides a kind of four-point supporting locking mechanism at this.
Utility model content
The purpose of this utility model is thoroughly to solve for a kind of the shortcoming and defect existed in high-low pressure assembled electric product door lock locking design, and ensure that the degree of protection of assembled electric product is upper and lower, left and right is consistent, cabinet door is smooth attractive in appearance, also can not carry because of product, shift or in-site installation key dimension error and occur the problem that barrier propterty declines, ensure that the four-point supporting locking mechanism that degree of protection when electric product manufactures with factory is identical; Realize about the utility model exchanging, front and back door-plate can be general, has good generalization performance, and adopt four-point supporting locking device, the security performance of electric product can further be promoted.
The utility model is achieved in that a kind of four-point supporting locking mechanism of structure, it is characterized in that: comprise locking bar, four locking devices, lock arm-tie, lock main body, lock core and dead bolt; Described dead bolt is installed on lock main body by installation shaft, dead bolt by two bearing pins respectively with lock arm-tie A with lock arm-tie B and be connected, and the two bearing pin lines of centres are through the center of dead bolt, wherein lock arm-tie A to be connected with locking bar A and locking bar B with the mode that lock arm-tie B is connected respectively by screw, locking bar A and locking bar B are provided with two locking devices; It is lock pressing plate below described lock main body; Described lock core is installed on the front end of lock main body, and is connected with locking closure in the mode of clamping on the top of lock main body; Described locking closure is for covering lock core, when not opening cabinet door ensure lock core not by the pollutant in the external world or dust affect.
