Description
Technical field
The utility model is related to a kind of gate lock for cabinet, more particularly to a kind of cam lock bar-type rack with reinforcement structure part
Door lock.
Background technology
Current rack is widely used in industry, network service, various fields of recent life as a kind of closed vessel, such as outdoor dress
Put the communication cabinet of electronic equipment, the electric switch put in power supply, the electric cabinet of control device, office building on production line
Netting twine, ammeter rack in rack and residential building etc..The security of gate lock for cabinet is the important structure for ensureing installation security in rack
Part, the main accurate performance and overall construction intensity by lock core structure of security of gate lock for cabinet ensures.Accurate performance Gao Kefang
Illegal unlock, overall construction intensity is high, can anti-violence picking lock.The especially electric appliance casing such as outdoor electric cabinet, communication cabinet, to protect
Internal unit safe operation is demonstrate,proved, the structural strength to door lock has high requirements.What application was wide at present is cam lock bar-type door
Lock, as shown in figure 1, being bar shaped cam lock bar-type gate lock for cabinet 1a, its structure mainly includes lock body 14a, lock core 11a, turns tongue
12a, will turn screw 13a, lock panel 16a and lock installed part 15a that tongue is fixed on lock core.In use, lock body is from cabinet door
Passed through on the outside of 21a by the lock mounting hole 24a being coincide with lock body profile, lock panel 16a is stuck on the outside of cabinet door 21a, this
When lock body is fixed on the inside of cabinet door by locking installed part 15a, close cabinet door, rotate lock core 11a, turn tongue 12a and produce, keep off
On the inside of doorframe 21a, the locking of cabinet door is realized.
Existing cam lock bar-type door lock is due to simple in construction, and locking is reliable, obtains extensive use, but its defect is that structure is strong
Degree is relatively low, does not possess and resists the structural strength that strength is forced open the door.As shown in Fig. 2 when being forced open the door with screwdriver 3a, turning tongue 12a stress
Tilt, the screw 13a stress that fastening turns tongue is maximum, will be broken lock core screwed hole thread damage or lock core, cause to turn tongue to come off
Door lock fails.The lock core of especially currently marketed gate lock for cabinet, typically using cast copper material or zinc alloy material, limited strength, because
The barrier propterty that this is collided to external force is relatively low.
In summary, the structural strength of cam lock bar-type gate lock for cabinet how is improved, anti-extraneous violence damage is made it have
Performance, as industry concerned issue.
Utility model content
Main purpose of the present utility model is in view of the above-mentioned problems, providing a kind of cam lock door bolt with reinforcement structure part
Formula gate lock for cabinet, so as to improve the performance of its anti-extraneous violence damage, ensures rack safety, cabinet equipment is normally run.
The utility model solves the technical scheme that its technical problem used：
A kind of cam lock bar-type gate lock for cabinet with reinforcement structure part, mainly including lock body, lock core turns tongue, will turn tongue
