Abstract

The utility model relates to a special lock head for compartment-car, comprising a lock hook, a lock base, a tip, a chip, a spring, a rotating shaft, a pin shaft, a handle, a bolt hole, a lock core, a billiard component and a locking sheet. the lock head is characterized in that the lock adopts dual-stability action mechanism, wherein, the lock base working as the bottom platform is fixed on the board of the rear door or the side door of the compartment through four bolts; a rotating shaft is arranged on the lock base, and the lock hook can rotate around the rotating shaft; the tip is fixed on a convex platform through a bolt, the spring is enclosed with the chip, a groove on one end of the chip is connected with the tip, the other end of the chip is connected with the pin shaft of the lock hook, and then the lock core, the locking sheet and the billiard component are assembled inside the lock hole; the lock hook is controlled by the key to be closed or opened.

Description

The special-purpose tapered end of a kind of railway carriage or compartment car

Technical field

The utility model relates to mechanical, the special-purpose tapered end of particularly a kind of railway carriage or compartment car.

Background technology

Development along with society, progress of science and technology, the car door of the goods vehicle closure compartment of present domestic operation, the general door locking device that adopts handle, vertical shaft, gib head, groove and lock to form, all reveal the external surface of putting at door, must pull handle earlier at closing time, the upper/lower terminal gib head that drives vertical shaft is aimed at and is entered among the groove on the railway carriage framework, turning handle makes gib head hook groove then, and handle is pressed among the nose, again with the bright lock of locking, this door locking device not only reveals to be put outside, and uses bright lock, poor safety performance; As shown in Figure 1, external thick stick lock for transport van, this lock is that a handle 8 of lock thick stick buckles in the socket joint hook 14, with 15 lockings of general cylinder lock, the shortcoming of this conventional method is that cylinder lock 15 is to separate with the railway carriage or compartment door, lose and the corrosion that drenches with rain easily, and also inconvenience of operation, anti-theft security is also poor.

The utility model content

According to the purpose of this utility model, at the existing shortcoming of above-mentioned closure compartment compartment door lock, provide a kind of railway carriage or compartment car special-purpose tapered end, its structure is to be made of latch hook, lock, top, chip, spring, rotating shaft, bearing pin, handle, screw, core, pellet shot from a slingshot group, door bolt sheet etc., its operating principle is a latch hook under spring, chip and top synergy, can produce F to lock shaft ₁And F ₂The active force of two kinds of different directions, thus make latch hook be in two kinds of different settling positions respectively, work as F ₁When working, latch hook produces a clockwise opplied moment around the shaft, makes lock shaft in the closed position at last; Work as F ₂When working, latch hook produces an anticlockwise opplied moment around the shaft, makes lock shaft be in the enable possition at last, so latch hook is a kind of bistable mechanism on lock, at F ₁Or F ₂Effect under, or in the closed position, or be in the enable possition: its structure is to be base frame with the lock, at the lock rear portion and the front portion respectively be provided with two bolts hole, be fastened to by screw on the door-plate of carriage back door or side door; On lock, be provided with a rotating shaft, latch hook can be rotated around rotating shaft; Be fixed on the corresponding boss top with screw, compression helical spring is inserted in chip, and an end groove of chip is connected with top, and the chip other end links to each other with bearing pin on the latch hook, this moment make spring be in certain compressive state, so spring just by chip directed force F ₁Or F ₂Be added on the bearing pin, make latch hook produce suitable, counterclockwise torque; Bearing pin is located on the flange of latch hook, is provided with a pit of being convenient to push at the upper surface of latch hook; Be provided with the pellet shot from a slingshot lockhole at its lock rear portion, be provided with cylinder lock in lockhole, it is made of lock core and door bolt sheet, pellet shot from a slingshot group, controls latch hook with key and is in and closes or opening.
