Description

The locking bolt destruction prevention device of lockset

The utility model relates to a kind of locking bolt destruction prevention device of lockset, refers to the device that a cost is low and anti-theft effect is good especially.

Public security worsens day by day at present, under the situation that everyone finds himself in danger, lockset is extensive use of by people, in numerous products, be that a kind of relevant design is as shown in Figure 4 arranged, mainly be the one-body molded lock body of characteristic that utilizes the kirsite light weight and easily process, wear lockhole A1 in lock body A inside and fit the lock tube A2 that the place protrudes out built-in core D in lockhole A1 top, make locking bolt E that sheathed spring F is mounted on lockhole A1, and controlled by core D, the multiple nose end that exposes that clogs lockhole A1 with cock body B; So, because of kirsite belongs to a softer material, some lock tube A2 edge sides are drilled with a hole over against locking bolt E place, can take out locking bolt E and make lockset lose the button effect of pulling; The base this, someone is in establishing once heat treated cock body C over against locking bolt E place plug, and the phase gives and prevents to take out locking bolt E, and is right, these safeguard procedures still can't effectively be checked, mainly be because of detaining the place of pulling in core D and locking bolt E, be drilled with a hole, pulling locking bolt E with the thin foreign object of point again, this locking bolt E is in the sheathed spring F of front end, broken away from locking bar so pass very easily, continuous locking bar can the extraction out also can illegally be opened; And for effectively addressing the above problem, have again lock body A is adopted iron material manufacturing and heat treatment person in addition, use and improve lock body A hardness; So, this kind manufacture cost is too expensive, improves the product price relatively, and iron material also belongs to heavy material, does to use and goes up conveniently smoothly not as Zinc-alloy, and the consumption market also is difficult to accept high price and awkward lockset.

Main purpose of the present utility model promptly is to provide a kind of locking bolt destruction prevention device of lockset, makes that its cost is low, anti-theft effect is good.

For reaching above-mentioned purpose, the utility model is mainly established by lock body, sleeve and sleeve pipe group and is formed; Wherein, this lock body is in distolateral moulding one a lock tube, and a lockhole and the vertical perforation of lock tube are also offered in the bottom side, in the built-in core of lock tube, establish locking bolt and spring in the lockhole, lock tube edge side is embedded a sleeve over against the lockhole place, and sleeve is the interior empty cylindrical shell of a monolateral opening, and its open edge side is cut and established the arc recess, and in the built-in sleeve pipe of lock tube, sleeve pipe is shaped to the perforation body of establishing tool arc recess, the arc notch end of suitable son handing-over sleeve, and sleeve and sleeve pipe just coat the core bolt of locking bolt and core.

In addition, the utility model sleeve and sleeve pipe are iron material, and utilize heat treatment to improve hardness.

After adopting said structure, the utility model assembling is simple, and only sleeve and sleeve pipe are iron material, and cost is low, and sleeve and sleeve pipe utilize heat treatment to improve hardness, and forms closed protective surface, good anti-theft effect.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is assembled sectional view of the present utility model (one);

Fig. 3 is assembled sectional view of the present utility model (two);

Fig. 4 is an assembled sectional view of commonly using product.

At first, see also shown in Figure 1, the utility model is established enforcement for 4 groups by cooperation locking units such as lock body 1, sleeve 2 and sleeve pipes 3, this locking unit 4 comprises members such as lock 41, locking bolt 42 and spring 43, wherein: lock body 1 wears lockhole 11 and empty lock tube 12 in the suitable place of end face protrudes out in the bottom side, fit and make a lockhole 11 and lock tube 12 vertical connecting, and offer consent 13 over against lockhole 11 places in lock 12 an edge side; Sleeve 2 be a monolateral opening and in heat treated empty cylindrical shell, be arranged with an arc recess 21 in its openend; Sleeve pipe 3 is wide and moulding in relevant sleeve 2 footpath and through heat treated perforation body, Yu Yiduan is arranged with arc recess 31 relatively.

When Yu Zushe implements, see also Fig. 2, shown in 3, make sleeve 2 with its arc recess 21 up relatively consent 13 plugs of lock body 1 establish, make locking bolt 42 sheathed springs 43 place lockhole 11 and be placed in sleeve 2 inside again, and with a cock body 5 obstruction lockholes 11 nose end openings, the continuous sleeve pipe 3 that makes is installed with by lock tube 12, suitable arc recess 31 with the one side joins in sleeve 2 edge sides, 31 of the arc recesses of side are fitted and are formed through holes that supply locking bolt 42 to place in addition, and make sleeve 2 and sleeve pipe 3 coat spring 43 and part locking bolt 42, then, load core 41 in lock tube 12, suitable make its core bolt 411 sleeve 3 butt locking bolts 42 that stretch through, and interlock mutually; By this; when if attempt is taken out locking bolt 42 with boring by the dead ahead of locking bolt 42; be one to be subjected to the assembly of Overheating Treatment then because of this sleeve 2 and sleeve pipe 3; so matter is difficult to drilling firmly; pry open locking bolt 42 from the side if desire to connect face place boring intention in thin lock body 1 and lock tube 12; then because of sleeve pipe 3 and sleeve 2 are the close and protect faces that form a quadrature, and tight can make foreign matter stretch supporting sled from locking bolt 42 and also be difficult to drill through sleeve pipe 3, causes the certain effect of an anti-theft effect and fit to give reaching.
