Specific embodiment
The invention will now be described in detail 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 22
One end of 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.Above-mentioned is interior
Handle 32 includes connecting rod 321 and extension bar 322, and connecting rod 321 is directly anchored to the lower end of shaft 1, and connecting rod 321 can
To be integrally formed with shaft 1, facilitate manufacture.Angle is 90 ° between connecting rod 321 and extension bar 322, and extension bar 322 is under
Angle between side plate 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, the right side
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 or interior in outside is pressed
The Internal handle 32 of side can start position-limit mechanism 3, realize the transverse movement backward of guide rod 23, adjoint spring 1 loosens and bullet
Spring 2 223 tightens, and unlocks and completes.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.
Simply to illustrate that technical concepts and features of the invention, its purpose is allows in the art above-described embodiment
Those of ordinary skill cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all
It is the equivalent changes or modifications that the essence of content according to the present invention is made, should be covered by the scope of protection of the present invention.
