Specific embodiment

According to the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figs 1-4, it is a kind of heavy shock door lock, describes in detail below to it.

It is a kind of it is heavy hit door lock, including shell 1, be located at lock body 2 in shell.Specifically, shell 1 include front side board 11, Back side panel 12, left plate 13, right side plate 14, epipleural 15, lower side panel 16 form, and above each side plate is fastened by bolts, whole A shell 1 is bolted on explosion-proof car door.It is equipped with securing plate 141 in the outside of right side plate 14,141 bolt of securing plate is solid It is scheduled on right side plate 14, plays the purpose of reinforcing.

As the lock body 2 of key effect, specific structure includes lock tongue 21, spring 22 and guide rod 23.For convenience of system It makes, lock tongue 21 and guide rod 23 among the above is integrally formed.The sum of length of lock tongue 21 and guide rod 23 is greater than the front side board 11 length is equipped with the fluting 131 to match with lock tongue 21 on left plate 13, is equipped with and 23 phase of guide rod on right side plate 14 Matched guide groove 231,23 one side-to-side movement on fluting 131 and guide groove 231 of lock tongue 21 and guide rod, realizes lock tongue 21 extend and retract.

Be limited the amplitude extended and retracted of lockmaking tongue 21, is mounted with limit plate 211, limit plate in the rear end of lock tongue 21 211 diameters are greater than 131 diameters of fluting, and limit plate 211 can be against on fluting 131, prevent the excessive of lock tongue 21 and guide rod 23 It stretches out.

Locating piece 221 is equipped on guide rod 23, there are two locating pieces 221, is located at 23 two sides of guide rod.Furthermore 211 a certain distance of positional distance limit plate that locating piece 221 is arranged, facilitates subsequent control guide rod 23.Spring mentioned above 22, the spring 22 in the present embodiment includes spring 1 and spring 2 223, and spring 1 is located at limit plate 211 and locating piece Between 221, spring 2 223 is between locating piece 221 and right side plate 14.Two springs, which are arranged, can be convenient for guide rod 23 Motion control, thus reach control lock tongue 21 movement.

It further include position-limit mechanism 3 and shifting fork mechanism 4 in the present embodiment, position-limit mechanism 3 can control lock tongue 21 in fluting 131 Interior side-to-side movement, shifting fork mechanism 4 can limit the side-to-side movement of lock tongue 21.

For above-mentioned position-limit mechanism 3, specific configuration is as follows:

Position-limit mechanism 3 includes shaft 1, Internal handle 32, outer handle 33 and limited location fork 34.Shaft 1 is located at spring One end of 22 lower section, shaft 1 is located in shell 1, and the other end of shaft 1 is passed through and stretched out outside back side panel 12.It is above-mentioned Internal handle 32 include connecting rod 321 and extension bar 322, connecting rod 321 is directly anchored to the lower end of shaft 1, connecting rod 321 can be integrally formed with shaft 1, facilitate manufacture.Angle is 90 ° between connecting rod 321 and extension bar 322, extension bar Angle between 322 and lower side panel 16 is 30 °.

For convenience of operation, opening 261 is equipped on lower side panel 16,322 other end of extension bar stretches out outside opening 261, convenient Hand makes power.By above design, realization has the technical effect that extension bar 322 pushes, and drives the rotation clockwise of shaft 1 Turn.

For the control for realizing lock tongue 21, limited location fork 34 is also provided in shell 1, limited location fork 34 is specifically mounted on shaft 1 Left upper end.Limited location fork 34 is the consistent baffle 341 of two structures, is spring 22 and guide rod 23, baffle between two baffles 341 are integrally formed with shaft 1, facilitate casting.Baffle itself includes one piece of connecting plate, one piece of limit plate, and connecting plate is mounted on In shaft 1, connecting plate a and limit plate b are designed as opening angle to the right, and angle is 160 °.Camber is designed in angle position Side c, arc-shaped side c can be in contact with locating piece 221 and can rotate clockwise generation relative displacement with shaft 1.Together Sample, another block baffle are also in contact simultaneously with the locating piece of 23 other side of guide rod and can be with the rotations clockwise of shaft 1 It changes the line of production raw relative displacement, two baffles move synchronously.By above structure, the rotation for having the technical effect that shaft 1 of realization Turn the rotation of drive limited location fork 34, baffle 341 rotates, and arc-shaped side c is pressed downward locating piece 221, generates relative displacement each other, causes Guide rod 23 moves backward, loosens with spring 1 and tightens with spring 2 223, realizes the movement backward of lock tongue 21, unlocks It completes.

For convenience of outside control, outer handle 33 is directly installed in the shaft 1 outside back side panel, outer handle 33 and downside Be equipped with 30 ° of angles between plate 16, press outer handle 33, shaft 1 rotates, and realizes the rotation of limited location fork 34, cause guide rod 23 to After move, loosen with spring 1 and tighten with spring 2 223, realize the movement backward of lock tongue 21, unlock and complete.

For convenience of the problem of locking of whole device, shifting fork mechanism 4 includes block 41 and shifting fork piece 42, and shifting fork piece 42 includes Piece 421 and hand plectrum 422 are protruded into, protrudes between piece 421 and hand plectrum 422 and sets 90 ° of angles.The upper position peace in back side panel 12 Shaft 2 43 is filled, the lower end for protruding into piece 421 is fixed on the non-center position of shaft 2 43, and block 41, which is fixed on, protrudes into piece 421 lower end.More to illustrate, hand plectrum 422 is located at except epipleural 15, and epipleural 15 is equipped with strip slot 251, The rear end of strip slot 251 is additionally provided with the annular groove 252 communicated, and hand plectrum 422 can move back and forth in strip slot 251 and can To be fixed on annular groove 252.

Implementation above has the technical effect that hand plectrum 422 moves right, and drives the rotary motion of shifting fork piece 42, shifting fork piece 42 and block 41 forward and move downward, final block 41 resists limit plate 211, limit the movement of lock tongue 21, realizes and locks Purpose.The length of above block 41 guarantees to block limit plate 211 when block 41 moves.

The present embodiment specifically operates as follows:

Unlocking action: the present embodiment is mounted on heavy striking door, can pass through front side board 11, back side panel 12, left plate 13, right side plate 14, epipleural 15, the installation of 16 bolt of lower side panel.When needing to carry out latching process, the outer handle 33 in outside is pressed Or the Internal handle 32 of inside can start position-limit mechanism 3, realize the transverse movement backward of guide rod 23, loosen with spring 1 Tighten with spring 2 223, unlocks and complete.When loosing one's grip, 21 return of lock tongue under the active force of spring 22.

It locks movement: when being locked, hand plectrum 422 is manually operated along strip slot 251, is finally fixed at ring In shape slot 252.Above to drive shifting fork piece 42 and block 41 forward and move downward, final block 41 resists limit plate 211, limitation Completion is locked in the movement of lock tongue 21.

Locking action: firmly push pressing, and lock tongue 21 is generated cross shear by hitting, move after 21 transverse direction of lock tongue and Moment is withdrawn, and when lock tongue 21 is reached in corresponding lock tongue slot, return under the action of spring 22 is shunk of lock tongue 21, completion is locked a door dynamic Make.

For above-described embodiment simply to illustrate that the technical ideas and features of the present invention, its purpose is allows this field Interior those of ordinary skill can understand the content of the utility model and implement accordingly, can not limit the utility model with this Protection scope.The equivalent changes or modifications that all essence according to the content of the present invention is made, should all cover in this reality With in novel protection scope.
