Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown in Figures 1 to 5: present embodiment discloses a kind of switchgear locksets, including doorframe 1, cabinet door 2, handle 3 and lock
Tool, cabinet door 2 are articulated with doorframe 1,3 connecting cabinet door 2 of handle, and the lockset of the present embodiment includes lock tongue 6, mandril 4 and oval crank 5,
Lower edge is equipped with spherical groove 11 on doorframe 1, is equipped with the first cavity 21, the second cavity 23 and rod cavity 24 in cabinet door 2, rod cavity 24
One end connects the first cavity 21, and the other end connects the second cavity 23, and 6 side of lock tongue is equipped with lock tongue protrusion 61, and 6 one end of lock tongue is equipped with
Hemisphere jut, the other end are equipped with dead bolt hole 63, and lock tongue 6 is set to the inside of the first cavity 21, lock tongue protrusion 61 and the first cavity
It is also attached by spring 62 and end cap 25 between 21, mandril 4 is set to inside rod cavity 24, and 4 one end of mandril connects dead bolt hole
63, the other end connects oval crank 5, and the center of oval crank 5 connects handle 3, torsional spring 31 is additionally provided between handle 3 and cabinet door 2,
The effect of torsional spring 31 is that handle 3 is made to be constantly in fixed state, such as horizontal device, has handle 3 with oval crank 5
Certain restoring force.
In order to make lock tongue 6 preferably enter to spherical groove 11, the doorframe 1 of the present embodiment is additionally provided with slope surface 12, when cabinet door 2
When closing, the hemisphere jut of lock tongue 6 connects slope surface 12, makes 6 retraction of lock tongue to the first cavity 21, subsequently into spherical groove 11
Inside.
It is as shown in Figure 6: when the surface of sphere of spherical groove 11 is greater than or equal to 180 degree, it may appear that lock tongue 6 can not be from spherical shape
The phenomenon that skidding off in groove 11 causes cabinet door 2 that can not open, therefore, when cabinet door 2 is opened, it is necessary to enable spherical groove 11
Drive 6 retraction of lock tongue to the first cavity 21, therefore the surface of sphere of spherical groove 11 is necessarily less than 180 degree, the spherical shape of the present embodiment
The range of the surface of sphere of groove 11 is 120-160 degree, wherein optimal surface of sphere is 150 degree.
Specifically, be attached between end cap 25 and the first cavity 21 by screw thread, when end cap 25 fastens, end cap 25
It is flushed with the upper edge of the first cavity 21.End cap 25 pushes down lock tongue 62, lock tongue 61 connecting springs of protrusion for connecting lock tongue protrusion 61
62。
As a preferred embodiment, lock tongue 6 is additionally provided with dead bolt hole 63, and cabinet door 2 is additionally provided with lockset 32, when 2 locking of cabinet door,
Lockset 32 is inserted into dead bolt hole 63.
The preferred aluminium alloy rod of mandril 4 of the present embodiment.
The card of mandril 4 is main inside rod cavity 24 in order to prevent, therefore gap between the two cannot be too small, between the two between
Gap is preferably greater than 2MM.
