Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model provides a kind of turning-bolt lock for standardization equipment cabin of motor train unit, makes it solve existing like product structure design not good enough, stability and the poor technical problem of safety.Its objective is and to be achieved through the following technical solutions.
A kind of turning-bolt lock, lock core is provided with in the pedestal of this turning-bolt lock, rotating shaft is connected with dead bolt through pedestal, lock core is connected with rotating shaft, the external diameter of pedestal is provided with mounting nuts and liner, the dead bolt end of rotating shaft is provided with dead bolt, keeper and locking nut, and the flatter of spindle outer diameter side is corresponding with the flat hole of keeper, dead bolt; This turning-bolt lock is installed on the installing hole of skirtboard by mounting nuts, and dead bolt is used for fixing the connection between skirtboard.Its structure design main points are provided with spring between described lock core and rotating shaft, is provided with the pin-and-hole of horizontally set in lock core, and pin inserts the pin-and-hole of lock core, and lock core and the spindle outer diameter of pin and spring both sides are respectively equipped with sealing ring, and lock core is spacing to be fixed in pedestal; The pin place inwall of pedestal is provided with base seat groove, and base seat groove is arrangement in " ten " font, and pin and base seat groove wedging, rotating shaft place of pedestal is provided with pin swivelling chute.Thus the rotating shaft of this turning-bolt lock drives rotation by lock core, rotating shaft drives dead bolt to rotate, and dead bolt does an angle of 90 degrees and rotates, and spring is used for the reset of lock core and rotating shaft; Meanwhile, the pin of lock core can only slide up and down in base seat groove, can not circumferencial direction motion.
The lock core link of described rotating shaft is provided with four square holes, and this end of lock core is provided with four directions projection, the protruding fit of four square holes of rotating shaft and the four directions of lock core, and four square holes of rotating shaft are protruding higher than the four directions of lock core; The aperture internal diameter of described pedestal is provided with packing ring, and packing ring is fixed in pedestal by the hole retainer ring spacing of base aperture, and lock core is fixed in pedestal by packing ring is spacing.By cubic carry-over moment between lock core and rotating shaft; Meanwhile, lock core withstands on packing ring by spring, and packing ring passing hole back-up ring is fixed.
The outer collar mouth side of described keeper is provided with projection, and the keeper side of pedestal circle mouth is provided with symmetrically arranged muscle post, the projection of keeper and the muscle post of pedestal is spacing offsets.Thus the angle that lock core rotates is located by keeper, spacing is 90 degree of rotations.
The bilateral symmetry of described dead bolt is provided with tapered end, and one end tapered end tilts to locking nut side in " V " font respectively.The tapered end of said structure is convenient to dead bolt and is inserted connected piece, locking connected piece.
The utility model reasonable in design, uses, easy to assembly, and stability, safety are good; It is suitable as turning-bolt lock and uses, and being connected and fixed for equipment cabin of motor train unit ex hoc genus anne product.

Detailed description of the invention
Now by reference to the accompanying drawings, the utility model structure and use are further described.As shown in FIG. 1 to 3, this turning-bolt lock comprises lock core 1, spring 3, rotating shaft 4, pedestal 5, liner 6, mounting nuts 7, keeper 8, dead bolt 9, locking nut 10, pin 11, its concrete structure is: be provided with lock core and rotating shaft in pedestal, rotating shaft is connected with dead bolt through pedestal, lock core and rotating shaft are connected by four directions projection and four square holes, namely the lock core link of rotating shaft is provided with four square holes, this end of lock core is provided with four directions projection, the protruding fit of four square holes of rotating shaft and the four directions of lock core, four square holes of rotating shaft are protruding higher than the four directions of lock core; The external diameter of pedestal is provided with mounting nuts and liner, and the dead bolt end of rotating shaft is provided with dead bolt, keeper and locking nut, and the flatter of spindle outer diameter side is corresponding with the flat hole of keeper, dead bolt.Meanwhile, spring is arranged between lock core and rotating shaft, is provided with the pin-and-hole of horizontally set in lock core, and pin inserts the pin-and-hole of lock core, and the lock core of pin and spring both sides and spindle outer diameter are respectively equipped with sealing ring 2, and lock core is spacing to be fixed in pedestal; The pin place inwall of pedestal is provided with base seat groove 501, and base seat groove is arrangement in " ten " font, and pin and base seat groove wedging, rotating shaft place of pedestal is provided with pin swivelling chute.The aperture internal diameter of pedestal is provided with packing ring 12, and packing ring is fixed in pedestal by the hole back-up ring 13 of base aperture is spacing, and lock core is fixed in pedestal by packing ring is spacing.The outer collar mouth side of keeper is provided with protruding 801, and the keeper side circle mouth of pedestal is provided with symmetrically arranged muscle post, the projection of keeper and the muscle post of pedestal is spacing offsets.The bilateral symmetry of dead bolt is provided with tapered end, and one end tapered end tilts to locking nut side in " V " font respectively.
During locking, because lock core withstands on packing ring by spring, the pin of lock core is limited in the base seat groove of pedestal; Therefore, lock core can not rotate by circumferencial direction, and rotating shaft can not be rotated by belt lock tongue.When opening, press under lock core with instrument key, the base seat groove of pedestal deviate from by the pin of lock core, and lock core just can rotate by circumferencial direction, and rotating shaft just can drive dead bolt to rotate.Meanwhile, because of the projection of keeper and the spacing reason of the muscle post of pedestal, lock core can only rotate within the scope of 90 degree.
Design feature of the present utility model: this turning-bolt lock is arranged on the installing hole of skirtboard by liner and mounting nuts, and pedestal is fixed by mounting nuts, dead bolt is used for being connected and fixed another skirtboard.The rotational angle of lock core is located by keeper, is only limited to 90 degree of rotations; Namely lock core is provided with pin, and pin can only slide up and down in the base seat groove of pedestal, can not move by circumferencial direction; Lock core and rotating shaft are by cubic carry-over moment, and lock core withstands on packing ring by spring, and packing ring passing hole retainer ring spacing is fixed in pedestal, thus make lock core, spring, rotating shaft is spacing is fixed in pedestal.The head aperture internal diameter of pedestal is provided with hole back-up ring, and hole back-up ring can be dismantled with Circlip tongs.Rotating shaft in pedestal is provided with sealing ring, and the external diameter of pedestal is provided with liner, makes this turning-bolt lock reach IP65 grade.
