Description

Automatic localization disk brake lock

The utility model relates to a kind of automatic localization disk brake lock, belongs to the locking device of locomotive.

Usually, the disc brakes of locomotive, mostly be to be located at the wheel between centers, by the folder sheet clipping disc brake dish of pulling, wheel shaft can't be rotated and reach the effect of the car braking of pulling, then the needs according to actual design are laid with some perforation on its disc brake dish, with the heat radiation, chip removal, the increase friction effect that improve the disc brake dish and prevent usefulness such as distortion.A kind of Brake disc lock for anti-theft of vehicle that cooperates plug-in use has appearred in the market, it is to utilize the behavior of structure that is laid with perforation on the disc brake dish, pass perforation on the disc brake dish via lockset in-to-in lock pin, and whole lockset is locked on the disc brake dish, the obstruction that causes the disc brake dish to rotate by lockset, and then can form a lock effect of pulling to locomotive.

Yet, lockset is firm to be locked on the disc brake dish in order to make, the thickness of lock pin must can have the structural strength of a certain degree, between the perforation of its lock pin and disc brake dish excessive nargin must not be arranged, so, when carrying out the lock hanging action of lockset, repeatedly key is pressed against on the card of disc brake dish lock pin, and mobile gradually lockset is after the sensation lock pin is aimed at perforation, key makes lock pin pass perforation to finish lock stopper work fully again, but, because the position of its disc brake dish is to be positioned at subaerial the next place, adds the physical constraints of parking space, and can't allow the user squat down fully or to bend over, with the hands grip simultaneously lockset and key, institute is so that its lockset still has its inconvenience on reality is used.

Main purpose of the present utility model is that a kind of automatic localization disk brake lock is provided, and makes the lock stopper of disc brake dish lock do more rapid, convenient.

Another purpose of the present utility model system provides a kind of automatic localization disk brake lock, except that increasing the convenience of using, and the operation of suitable parking space when not enough.

The utility model realizes that the technical scheme of above-mentioned purpose is:

A kind of automatic localization disk brake lock mainly comprises lock body, lock tube, lock pin, screens pin; Lock body is the assembling main body of whole lockset, forms the insertion groove of disc brake dish on it, forms three in the upper place of insertion groove and overlaps mutually posthole arranged side by side; The lock tube fixedly is placed in by covering of loam cake in the middle posthole, the lock core bottom forms salient point, the lower end of lock tube is nested with the single-revolution dish, the lock core bottom is inserted in the formation trepanning of rotary disk bottom, and form protruding grain in the trepanning and just cooperate with the salient point of lock core bottom, lock tin and rotary disk between and be provided with torsion spring; Form a skewed slot and an inverted "L" shaped guide groove in addition in the Pan Bi both sides of rotary disk; Lock pin, screens pin all are a direct rod shape, and be placed on respectively in two postholes of lock body side by covering of loam cake, each corresponding skewed slot of the side of lock pin, screens pin and guide groove cooperate and form nose bar, respectively are provided with one between the top of lock pin, screens pin and the loam cake and can make it connect the hole by posthole bottom one stretching into compression spring in the insertion groove; The bottom of screens pin forms pushing and turning surface, and the nose bar of screens pin is in vertical section of inverted "L" shaped guide groove, and the nose bar of lock pin then just is in the top of skewed slot, and to the restriction that is rotarily formed of rotary disk.

This lock tube upper end one side forms the lug with aperture, and rotary disk pushes up along the last aperture that also forms, and insert respectively in the aperture of lock tube and rotary disk at the two ends of torsion spring.

This lock body upper surface forms four hole clippings, and loam cake is by four card posts and four corresponding covering on lock body of hole clipping of its below, finish lock tin, the assembling of lock pin and screens pin.

The utility model is by at the insertion groove of lock body and affect between the rotary disk of lock pin action, be provided with one and can limit the screens pin that rotary disk moves, and an end of screens pin is stretched in the insertion groove, when the disc brake dish stretches into insertion groove, can stir screens pin in the insertion groove via the disc brake dish, and make lock pin fall in the insertion groove automatically, and be pressed against on the card of disc brake dish, only need lock body is moved towards the perforation on the disc brake dish, its lock pin can stretch into perforation automatically and disc brake dish lock is pulled, the lock stopper that reaches Brake disc lock for anti-theft of vehicle is done more rapid, purpose easily, simultaneously, make the user be hold by one hand lock body and do not need rotary disk key separately, be fit to parking space operation when not enough.

Below in conjunction with drawings and Examples, the utility model is further described.
