Description

A kind of bar-bell type lockset

Technical field

This utility model relates to field of lockset, is specifically related to a kind of bar-bell type lockset.

Background technology

The lock body structure of the most removable lockset is mostly enclosed ring, and anti-shearing functions is poor.And most locksets are come Saying, as long as cutting off a bit, whole lockset will be ineffective.Existing most of lockset or the big (example of the insufficient strength of entirety Such as chain type lock), otherwise entirety is relatively thicker, but junction is weaker, it is easy to and pounded disconnected or cut off, so that whole Lockset is ineffective.If in order to ensure that there is enough intensity junction, then needing to increase bulk strength, whole lockset will be non- The heaviest, manufacturing cost also can increase.

Utility model content

The purpose of this utility model is to provide a kind of shear-stable bar-bell type lockset.

Based on above-mentioned purpose, this utility model by the following technical solutions: a kind of bar-bell type lockset, including left lock body and the right side Lock body, left lock body and right lock body slides and is provided with ring-type catch, be provided with lock core in right lock body, and the right-hand member of right lock body is provided with ring-type convex Rise；The right-hand member of left lock body be provided with lock core with the use of tapered end, the left end of left lock body is provided with annular projection；Ring-type catch is located at Inside annular projection, the diameter of annular projection is more than the diameter of ring-type catch centre bore.The inside kayser that lock core is formed with tapered end Can be that traditional keys locks (end that keyhole is located at right lock body), mechanical code lock, electronic password lock or Intelligent remote control lock.

Further, the cross section of described left lock body and right lock body is circular or square, the shape of the centre bore of annular catch Shape is consistent with the shape of left lock body and the cross section of right lock body.

Further, left lock body and right lock body there is a piece of or two panels and respectively with upper annular catch.

Further, described ring-type catch is circular, square or bowl-type.

Further, described ring-type catch is the two panels congruent form catch that concave surface is welded by bowl-type catch concave surface.

Further, described ring-type catch is the two panels congruent form catch that convex surface is welded by bowl-type catch convex surface.

Further, described ring-type catch is corrugated surface.

Further, left lock body is connected with the ring-type catch lower end on right lock body, forms a U-shape structure.

Further, being fixedly connected with sleeve pipe in the centre bore of described ring-type catch, sleeve pipe is sliding with left lock body and right lock body Dynamic cooperation.

Compared with prior art, this utility model has the advantage that

(1) the lockset intensity height of this utility model offer, simple in construction, low cost, this utility model is easy for common lockset Tear " line " (closed-loop) cut off open strengthening is the most readily removable " face " (the ring-type catch) cut off, and whole lockset does not exist the ground of weakness Side, is possible to prevent failure by shear, improves security performance；

(2) diameter of annular projection is more than the diameter of catch centre bore, is possible to prevent ring-type catch from the landing of lockset two ends；

(3) being slidably matched of ring-type catch and left lock body and right lock body, is convenient for changing and moves ring-type catch, according to being locked The size of object endoporus, selects appropriately sized ring-type catch, makes the diameter of ring-type catch or catercorner length more than being locked The interior interporal lacuna of object, can realize the effect of locked locked object body；

The lower end of (4) two ring-type catch is connected, and forms a U-shape structure, is possible to prevent the locked object bodies such as wheel to turn Dynamic, strengthen locked ability；

(5) being fixedly connected with sleeve pipe in the centre bore of ring-type catch, anti-the tearing open that can improve lockset cuts function；

(6) ring-type catch is corrugated surface, can strengthen the intensity of catch, and anti-the tearing open improving lockset cuts function.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in detail.

Embodiment 1

A kind of bar-bell type lockset, its structure as shown in figures 1-8, is circular or square left lock body 1 and right lock including cross section Body 2, if sliding the diameter being provided with one or more pieces ring-type catch 4(annular projections 5 more than being locked on left lock body 1 and right lock body 2 The interior interporal lacuna of object 3, it is possible to do not set ring-type catch 4), lock core 7 is installed in right lock body 2, the right-hand member of right lock body 2 is provided with ring-type Protruding 5；The right-hand member of left lock body 1 be provided with lock core 7 with the use of tapered end 6, the left end of left lock body 1 is provided with annular projection 5；Ring-type Catch 4 is located at inside annular projection 5, and the diameter of annular projection 5 is more than the diameter of ring-type catch 4 centre bore.Lock core 7 and tapered end 6 The inside kayser formed can be that traditional keys locks (end that keyhole is located at right lock body 2), mechanical code lock, electronic password lock Or Intelligent remote control lock.Left lock body 1 is through locked object body 3, and lock core 7 forms blocking, lock core 7 and lock with tapered end 6 after being socketed 6 are separated into unlocking condition.

Ring-type catch 4 on left lock body 1 and right lock body 2 is separate, and ring-type catch 4 is circular (as shown in Figure 2), bowl-type (as shown in Figure 6) two panels congruent form catch (as shown in Figure 7) that, convex surface is welded by bowl-type catch convex surface, bowl-type catch concave surface pair Two panels congruent form catch (as shown in Figure 8) of concave surface welding or other can strengthen the shape of anti-shearing functions.When ring-type catch 4 is Corrugated surface (as shown in Figure 4 and Figure 5), can strengthen the intensity of catch, and anti-the tearing open improving lockset cuts function.

It is fixedly connected with sleeve pipe 8(in the centre bore of ring-type catch 4 and also can not set sleeve pipe 8), sleeve pipe 8 and left lock body 1 and the right side Lock body 2 is slidably matched, and sleeve pipe 8 can improve the intensity of lockset.The diameter of annular projection 5 is straight more than ring-type catch 4 centre bore Footpath, is possible to prevent ring-type catch 4 from the landing of lockset two ends；The diameter of ring-type catch 4 or catercorner length are more than locked object body 3 Interior interporal lacuna, according to the size of interporal lacuna in locked object body 3, select appropriately sized ring-type catch 4, make ring-type catch 4 Diameter or catercorner length more than the interior interporal lacuna of locked object body 3, can realize pinning the effect of locked object body 3.Locked Object 3(is as a example by tire) rotate time, the cantilever of locked object body 3 both sides can stop that lockset moves, so stop locked object body 3 turns Dynamic.

It is antitheft that above-mentioned bar-bell type lockset can also be used for gate, as it is shown in figure 9, bar-bell type lockset through door body 10 handle or Locking function is realized after lockset fixing hole.

Embodiment 2

A kind of bar-bell type lockset, as shown in Figure 10.It is with the difference of embodiment 1: the lower end of two ring-type catch 4 It is connected, forms a U-shape structure 9, be possible to prevent locked object body to rotate, strengthen catch intensity.
