Abstract

The utility model relates to railway signals facilities, in particular to an anti-theft composite transformer tank, which comprises a tank body, a tank cover and a lock, wherein the lock is arranged inside the tank cover, a lock claw is integrally connected with the tank body, the lock is composed of a lock core, a deflector rod and a lock bolt, the deflector rod rotates with the lock core and moves from left to right, one end of the deflector rod is fixed on the lock core while the other end is inserted into a hollow chamber of the lock bolt, and a spring arranged between one end of the lock bolt corresponding to the lock claw and the inner wall of the lock is used for pushing against the lock bolt to move forward to mesh with the lock claw. The utility model with a built-in regular pentagon anti-theft lock has the advantages of good anti-theft effects, fine strength, easy and convenient manufacture, and relative low manufacture costs.

Description

Anti-theft type composite material transformer chamber

Technical field

The utility model relates to the railway signal facility, especially a kind of anti-theft type composite material transformer chamber.

Background technology

The signal transformer case is the important device that railway interests is used to guarantee traffic safety, initial stage, the railway signal transformer tank is an ironcasting, used composite materials such as modification of nylon to make afterwards, overcome the heaviness of ironcasting, the cost height, shock resistance is poor, the breakage rate height, weatherability is poor, easily produce shortcomings such as static, after again on this basis through improving, the special-purpose lock of railway is for built-in, but existing this class composite material railway signal transformer tank still exists some shortcomings so generally: lockset is made numerous and diverse, the opening and closing inconvenience, troublesome maintenance, and the manufacturing cost of lock is higher relatively; The theftproof performance of lock is poor; Existing this class composite material railway signal transformer tank generally all is provided with the muscle of gaining in strength, but the reinforced effects of muscle still comes with some shortcomings.

The utility model content

The technical problems to be solved in the utility model is: the special-purpose locking of existing railway is made in order to overcome, troublesome maintenance, the manufacturing cost height, and theftproof performance is poor, and the problem of undercapacity etc. provides a kind of anti-theft type composite material transformer chamber.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of anti-theft type composite material transformer chamber, comprise casing, case lid, lock and lock pawl, described lock is built in case lid, lock pawl disjunctor is in casing, described lock comprises lock core shift lever and dead bolt, rotate driving lever one end of swinging with lock core and be fixed on the lock core, in the cavity that is provided with on the other end insertion dead bolt, push the dead bolt reach and lock the spring that pawl meshes with respect to being provided with between the phase far-end of locking pawl and the lock inwall on the dead bolt.

The head cross section that is used for matching with key on the described lock core is positive pentagon.Herein will be good with respect to the special-purpose lock of original railway theftproof performance many.

Only be provided with a dead bolt and lock pawl in the described lock, the head that matches with the lock pawl on the dead bolt is provided with an inclined-plane, and the lock pawl is provided with at least two grooves that are arranged above and below successively, and any one all can match with the inclined-plane of dead bolt in the described groove.Have only a dead bolt and lock pawl, saving of work and time, make easyly, reduce cost.

The beneficial effects of the utility model are: this anti-theft type composite material transformer chamber, use built-in positive pentagon anti-theft lock, and theftproof performance is good; Intensity is good; Simple for production; Production cost reduces relatively.

Description of drawings

In conjunction with the accompanying drawings and embodiments the utility model is further specified down.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Fig. 3 is the A-A cutaway view Amplified image on Fig. 2.

Among the figure: 1. casing, 11. lock pawls, 2. case lid, 3. lock, 31. lock cores, 32. driving levers, 33. dead bolts.

Embodiment

Shown in accompanying drawing 1,2, anti-theft type composite material transformer chamber is made up of casing 1 and case lid 2, and lock 3 is built in case lid 2, and the head cross sectional shape that lock core 31 matches with key is positive pentagon.

As shown in Figure 3, described lock 3 comprises lock core 31, dead man 32 and dead bolt 33, rotating driving lever 32 1 ends of swinging with lock core 31 is fixed on the lock core 31, the other end inserts in the cavity of setting on the dead bolt 33, pushes dead bolt 33 reaches and locks the spring that pawl 11 meshes with respect to being provided with between the phase far-end of locking pawl 11 and lock 3 inwalls on the dead bolt 33.

As shown in Figure 3, also specifically described the course of work of this railway special-purpose theft-proof lock, rotated by driving lever 32 pulling dead bolts 33 release lock pawls 11, can open case lid 2 by lock core 31; Be connected with spring with respect to an end of lock pawl 11 with locking between 3 inwalls on the dead bolt 33, on the dead bolt 33 inclined-plane is arranged, on the lock pawl 11 groove is arranged, in conjunction with the groove on the inclined-plane of dead bolt 33, the lock pawl 11 and the effect of spring, when being closed, locks case lid 2 on the 3 energy automatic lockings, lock pawl 11 as shown in Figure 3 and be provided with three grooves that are used for 33 engagements of groove dead bolt, can guarantee the seal of case lid 2 on casing 1 under the situation that case lid 2 is exerted pressure like this.

This anti-theft type composite material transformer chamber adopts composite material moulded making, and also is provided with reinforcement for gaining in strength on the inwall of casing and case lid in addition.
