Description

Safety electric cabinet lock

Technical Field

The utility model relates to an electrical equipment specifically is a safe electric cabinet lock.

Background

Usually, the lock back and the lock body of the electric cabinet lock are bound to have mutually related movable parts, for example, the lock back is embedded in the lock body through the accommodating concave part of the lock body, a gap exists between the lock back and the lock body, and the lock cylinder is inserted into the accommodating coupling hole and other parts of the lock body at the corresponding end of the lock back, rainwater easily flows into the lock body from the matching gap between the lock back and/or the lock body outside the lock body through the matching parts of the movable parts such as the lock cylinder and the accommodating coupling hole, so as to damage the internal electronic elements, even flow into the electric cabinet box to damage equipment. The existing similar electric cabinet lock has the protection problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a safe electrical cabinet lock to the not enough of above-mentioned prior art existence, this safe electrical cabinet lock structure is extremely simple, reasonable, and the protecting effect is good, uses safe and reliable.

The utility model discloses technical scheme of safe electric cabinet lock includes the lock body, the lock back, fixed connection in the lock core of lock back one end is located the holding portion of lock body, the holding portion including locate the corresponding wall of lock body, with the holding recess that the lock back corresponds, and locate the corresponding one end of this holding recess of lock body, corresponding to the holding coupling hole of lock core still includes a safety device, safety device including set up in sealing device between the lock core of lock back and the holding portion of lock body.

The sealing device comprises an inclined sealing surface arranged on the bottom wall surface of the containing groove of the lock body and a joint part of the corresponding end of the containing coupling hole, and a sealing ring which is sleeved on the lock core of the lock back and corresponds to the inclined sealing surface.

The sealing device comprises an annular sealing table surface arranged on the lock core of the lock back and a sealing ring which is arranged in the accommodating part of the lock body and corresponds to the annular sealing table surface.

The sealing ring is an O-shaped sealing ring or a sealing gasket.

The utility model discloses a corresponding position in the holding portion of lock core and lock body sets up sealing device to the line face formula sealing mode makes the corresponding outside of lock back and lock body and the inside reliable waterproof sealing of forming of lock body keep apart, and then fundamentally has solved the unable sealed problem of connecting portion of lock back and the mutual movable part of lock body. Meanwhile, the lock core can be moved to form an avoiding guide effect, so that the corresponding volume of the lock can be reduced, and the sealing reliability of the lock back and the lock body is further improved.

Detailed Description

For further understanding of the present invention. The present invention will now be described more fully hereinafter with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the safety electric cabinet lock of the present invention includes a lock body 1, a lock back 2, a lock core 3 fixedly connected to a corresponding end of the lock back, and a sealing device disposed between the receiving portion of the lock body and the lock back or the lock core. The containing part of the lock body 1 comprises a lock back containing groove 6 arranged on the lock surface of the lock body, a cylindrical lock core containing coupling hole 5 arranged at one end corresponding to the lock back containing groove of the lock body, and the like.

The sealing device comprises an O-shaped waterproof soft rubber sealing ring 4 arranged on the peripheral wall of the upper entity part of the lock cylinder 3, an inclined sealing plane 10 arranged on the bottom wall surface of a lock back accommodating groove 6 of the lock body 1 and the joint part of the corresponding port of the lock cylinder accommodating coupling hole 5, and the like. The inclined sealing plane 10 can be formed by a 45-degree inclined plane formed by the bottom wall surface of the lock back accommodating groove 6 and a circle intersection angle chamfer of the peripheral wall surface port of the lock cylinder accommodating coupling hole 5. The O-shaped waterproof soft rubber sealing ring 4 can be arranged on the lock core through an annular groove arranged on the peripheral wall surface of the solid part at the upper part of the lock core 3.

When the lock back is pressed, the lock core enters the lock core accommodating coupling hole, and after the lock core is pressed in place, the electromagnetic valve telescopic rod 8 in the lock body extends out of the guide hole 7 formed in the lock body and is meshed with the lock tongue 9 on the lock core, so that locking is achieved. In this state, the O-shaped waterproof flexible glue sealing ring on the lock cylinder and the corresponding port of the lock cylinder accommodating coupling hole of the lock body (i.e. the lock cylinder inlet end at one end of the lock back accommodating groove of the lock cylinder accommodating coupling hole) form a line-surface type seal, so that the lock back accommodating groove of the lock body and the inside of the lock body form an effective reliable waterproof sealing isolation. The problem that a sealing device cannot be arranged and cannot be sealed on the connecting part of the mutually movable components of the lock back and the lock body is fundamentally solved.

And because the entry end of the lock cylinder holding coupling hole is an inclined plane to form a horn mouth, the lock cylinder can be in an arc-shaped running track to form a guiding, avoiding and guiding function, so that the lock cylinder holding coupling hole can be relatively smaller, the sealing difficulty of a movable part connecting part between the lock back and the lock body is relatively reduced, and the sealing reliability of the lock back and the lock body is further improved.

The utility model discloses in another embodiment, the lock core holding coupling orifice department of the back of the lock holding recess of its lock body is equipped with sealed plane recess, on this sealed plane recess was arranged in to its sealing washer, the upper end root perisporium of lock core was equipped with decurrent, correspond the sealed mesa of complex annular with the sealing washer on this sealed plane recess, its sealing washer is higher than the diapire face of back of the lock holding recess under no pressure state, it is playing under corresponding waterproof sealing's the condition, behind the lock of opening, can play the isolation to remaining in the ponding of back of the lock holding recess, avoid the infiltration inside the lock body. The sealing ring and the sealing plane groove can be an anti-drop rubber sealing gasket or an O-shaped rubber sealing ring which is in tight fit. The rest of the structure and the corresponding sealing method of this example can be similar to the above-mentioned embodiment.
