Description

The railway signal transformer box

Technical field

The utility model relates to the railway signal facility, especially a kind of railway signal transformer box.

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 box is an ironcasting, afterwards, composite materials such as use modification of nylon are made, overcome the heaviness of ironcasting, the cost height, shock resistance is poor, the breakage rate height, weather resisting property is poor, easily produce static, shortcomings such as easy-to-rust, the signal transformer case kind that existing this composite material is made is more, but exists some shortcomings so generally: 1, the iron lockset of external easily rust is dead, the opening and closing inconvenience, troublesome maintenance, and the theftproof performance of external lock is poor; 2, mounting hole place on the base is four microtias that extend outward the end of from, and the intensity difference of microtia makes the fixed performance of signal transformer case bad; 3, existing this class composite material railway signal transformer box generally all is provided with the muscle of gaining in strength, but the enhancing effect of muscle still comes with some shortcomings; 4, case lid is similar to a kind of flat cover, and the degree of depth is more shallow, even be provided with sealing band, because structural reason, its protection against the tide, antisoiling effect and insufficient.

Summary of the invention

Easily become rusty in order to overcome existing external, theftproof performance is poor, the deficiency of intensity difference and protection against the tide, antisoiling weak effect, the utility model provides a kind of railway signal transformer box, this railway signal transformer box not only intensity is good and moistureproof, antisoiling effective, and adopts built-in lock antirust, antitheft.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of railway signal transformer box, comprise casing, case lid, lock and mounting ear, and described lock is the special-purpose lock of built-in theftproof self-locking railway.The key of this lock is the special-purpose lock of railway with triangle concave inward structure, and can a key general, lock be built in locking closure, can be antitheft antirust.Lock is by rotational lock core, inserts or the separating lock pawl in conjunction with acting force of the spring pulling dead bolt, and lock pawl disjunctor is in casing.

Described mounting ear is for being positioned at bottom half to the extended wing in both sides.Enhancing has been done in the intensity aspect of original mounting ear herein, two mounting ears on every limit have been fused, formed the version that is similar to wing.

On the border of the corresponding joint with casing of described case lid, case lid is border inverted " U " type groove, is the protruding circle of the inverted T-shape in border on the casing.The protruding circle of this " U " type groove and T-shape has played the effect of reinforced rib simultaneously at the oral area of case lid and casing.Described " U " and " T " are the shapes of oral area section.

At the bottom of the type groove of border inverted " U " sealing band is arranged on the described case lid.

The protruding circle of the inverted T-shape in border is arranged on the above-mentioned casing, also can be " L " type as another kind of structure.

The beneficial effects of the utility model are: this railway signal transformer box not only intensity is good, moistureproof, dustproof, cold-resistant heat-resisting effective, and adopts built-in lock antirust, antitheft.
