Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1, the civil air defense door peace warfare conversion auxiliary device comprises a locking mechanism 1, a hooking mechanism 2, a transmission mechanism 3 and a limiting mechanism 4;
the locking mechanism 1 locks the door leaf 01 in the door frame 02;
the hooking mechanism 2 enables the door leaf 01 and the door frame 02 to enter a hooking state at the moment when the door leaf 01 swings into the door frame 02;
the transmission mechanism 3 is used for linking the locking mechanism 1 and the hooking mechanism 2, and is used for linking the hooking mechanism 2 to be disengaged when the locking mechanism 1 is locked, so that the hooking state of the door leaf 01 and the door frame 02 is released;
the limiting mechanism 4 keeps the hooking mechanism 2 in a releasing state after the hooking mechanism 2 is released, and releases the hooking mechanism 2 after the door leaf 01 is pulled open, so that the limitation on the releasing state of the hooking mechanism 2 is released.
During the closing process of the door leaf 01, the locking tapered end 13 on the door leaf 01 is difficult to insert into the locking hole of the door frame 02 due to the extrusion rebound action of the sealing rubber strip 04 on the inner side of the door frame 02 on the door leaf 01. However, when the door 01 is closed, the door 01 is hooked and fixed to the door frame 02 by the hooking mechanism 2 at the moment when the door 01 collides with the joint strip 04 by the inertia of the door 01, and at this time, the locking head 13 can be easily inserted into the locking hole by driving the locking mechanism 1. When the door leaf 01 is opened by the driving locking mechanism 1, the hanging hook mechanism 2 can be opened by the transmission mechanism 2, the hanging hook mechanism 2 can be locked by the limiting mechanism 4, the hanging hook mechanism 2 is prevented from fixing the door leaf 01 and the door frame 02 together again, after the door leaf 01 is opened, the hanging hook mechanism 2 is loosened by the limiting mechanism 4, and the hanging hook mechanism 2 is restored to complete the full civil air defense door peace fight conversion. The most laborious step in the whole process is to push the door leaf 01 tightly and drive the locking mechanism 1 when closing the door leaf 01, and the process is now carried out by the hooking mechanism 2 instead of manpower, thus saving manpower. After the locking mechanism 1 is locked, the hook mechanism 2 is immediately released, when the door is opened, the door leaf 01 is pulled open just by opening the locking mechanism 1, and no extra operation step is generated as in the normal door opening, and the limiting mechanism 4 limits the hook mechanism 2 in the process to prevent the hook mechanism from hooking and fixing the door leaf 01 and the door frame 02 again. After the door leaf 01 is opened, the limiting mechanism 4 is disengaged, the hook mechanism 2 is reset, the complete civil air defense door peace fight conversion is completed, and meanwhile, the next civil air defense door peace fight conversion is convenient.

The door latch seat 21 is used for fixing the door latch 22 and the latch return spring 24, and simultaneously plays a role in enhancing the connection strength of the door latch 22 and the door 01. The ratchet part 221 facilitates the limiting mechanism 4 to lock and limit the door leaf lock catch 22, and the hook part 222 and the bump button 23 are mutually matched in a hook-shaped structure, so that the door leaf lock catch 22 and the bump button 23 are conveniently locked and fixed. The latch return spring 24 can return the door latch 22 in time when the limit state of the limit mechanism 4 is released. The door leaf lock catch 22 is rotated around the shaft by the stress part 223 under the action of the lock catch return spring 24 and the transmission mechanism 3, and the locking and the releasing of the door leaf lock catch 22 and the bump catch 23 are realized in a simple rotation mode, so that the door leaf lock catch is economical, practical and reliable.
To illustrate further, the transmission 3 includes a linkage rod 31, a cam plate 32, and a push rod 34; the axial thickness of the cam plate 32 is spirally gradually changed; the linkage rod 31 connects the locking mechanism 1 and the cam disc 32, the cam disc 32 is driven to rotate by the linkage rod 31 when the locking mechanism 1 moves, and the cam disc 32 drives the push rod 34 to horizontally move so as to push the door leaf lock catch 22 to rotate in a vertical plane.
By means of rotation of the cam plate 32, displacement of the locking mechanism 1 is converted into horizontal displacement of the linkage rod 31, rotation control of the door leaf lock catch 22 is achieved, the transmission process is simple and easy to achieve, and stability and reliability of transmission are guaranteed.
To illustrate further, the limiting mechanism 4 includes a pawl 41, a pawl return spring 42, and a return block 43; the pawl 41 is disposed on the door latch seat 21 and rotates in a vertical plane around an axis, one end of the pawl 41 is a hook-shaped portion 411, which limits the door latch 22, the other end of the pawl 41 is an arched portion 412, and the arched portion 412 is higher than the hook-shaped portion 411; the reset block 43 is arranged on the door frame 02, and the pawl reset spring 42 is connected with one hooked end of the pawl 41 and the door leaf lock catch seat 21; the reset block 43 is a protrusion arranged on the door frame 02, and when the arch part 412 moves to the reset block 43, the arch part 412 is pressed by the reset block 43 to rotate around the shaft.
The limit mechanism 4 needs to be released from the door lock 22 and the catch 23 when the locking mechanism 1 is fully closed, and reset when the door 01 is opened. Through the cooperation of arch portion 412 and reset piece 43 for pawl 41 can loosen door leaf hasp 22 when opening door leaf 01 and make its automatic re-setting, and this kind of design makes the reset opportunity more reasonable, can not appear pawl 41 to advance or delay to loosen and lead to the process of opening the door to be obstructed.
To illustrate further, the transmission 3 further comprises a buffer spring 33 and a thrust ball bearing 35; the thrust ball bearing 35 and the buffer spring 33 are sequentially arranged in a groove on the outer side of the cam plate 32; when the buffer spring 33 is compressed, a force is applied to the cam plate 32 in the axial direction of the rotation shaft.
The buffer spring 33 prevents the rigid force damage generated between the cam plate 32, the push rod 34 and the lock catch due to the tight locking between the door lock catch 22 and the lock catch 23 in the initial stage. The thrust ball bearing 35 receives an axial load and pushes the push rod 34 to move by the rotation of the cam plate 32.
To illustrate further, the locking mechanism 1 comprises a connecting rod 11, a locking seat 12 and a locking head 13, wherein the locking head 13 slides in the locking seat 12 under the pushing of the connecting rod 11; the linkage rod 31 is of a bending structure, and two ends of the linkage rod 31 are respectively fixed in the sliding grooves of the swing arms of the locking lock 13 and the cam plate 32; when the link 11 moves linearly in the vertical direction, the cam plate 32 rotates around the shaft by the transmission of the link lever 31.
The locking seat 12 plays a role in fixing the locking head 13. The linkage rod 31 is fixedly connected with the sliding groove of the cam plate 32, so that the installation and the disassembly are convenient.
Further describing, the hook-shaped outer sides of the door leaf lock catch 22 and the latch 23 are arc-shaped structures.
When the door leaf 01 is closed, the outer sides of the door leaf lock catch 22 and the bump catch 23 are arc structures, so that the door leaf lock catch 22 and the bump catch 23 can smoothly transition when the door leaf lock catch 22 and the bump catch 23 collide, and the door leaf lock catch 22 and the bump catch 23 are hooked with each other more easily.
To illustrate further, the locking cylinder 13 is a wedge cylinder.
When the door leaf 01 is closed, if the closing degree is insufficient to enable the locking head 13 to directly and completely push into the locking hole of the door frame 02, the locking head 13 can still be completely pushed into the locking hole by utilizing the structural characteristic of the wedge shape when the locking mechanism 1 is driven because the wedge-shaped locking head of the locking head 13 can firstly enter a part of the locking hole.
To further illustrate, the reset block 43 is disposed on a side of the door frame 02 near the door leaf, and the reset block 43 is an arc-shaped protrusion.
The arc-shaped reset block 43 can not be blocked when contacting with the reset pawl 41, and the loss of the pawl 41 is small.
To explain further, in a state where the door leaf 01 is kept open, the door leaf latch 22 is kept in a horizontal state by the latch return spring 24 and the transmission mechanism 3.
It can be ensured that the door leaf latch 22 can be easily hooked with the catch 23 without easily falling off.
When the door leaf 01 performs peace fight conversion, the specific operation steps are as follows: only one person is needed to withdraw the jack for supporting and fixing the door leaf 01, the handle of the door leaf 01 is pulled, the door leaf 01 is pulled to the closed position, the inertia of the door leaf 01 is utilized, the resilience force generated by extrusion of the sealing rubber strips 04 in the sealing grooves around the door frame 02 is overcome, and the door leaf 01 is buckled by the door leaf lock catch 22 of the door leaf 01 opening and closing conversion auxiliary device at the moment that the door leaf 01 contacts the door frame 02.
After the door leaf 01 is buckled by the lock catch, an operator can easily insert four locking tapered ends 13 on the door leaf 01 into locking holes of the door frame 02 by rotating a hand wheel of a locking mechanism 1 of the door leaf 01, so as to lock the door leaf 01 in place.
The other door leaf 01 is locked in place by the same method, so that the door leaf 01 plays roles of sealing, isolating biochemical toxicants and resisting the impact of explosion shock waves, and the protective function of protective equipment in the war is realized.
After the door leaf 01 is buckled by the door leaf lock catch 22, a hand wheel of the locking mechanism 1 is rotated, and in the process of inserting four locking lock heads 13 on the door leaf 01 into locking holes of the door frame 02, under the linkage action of the linkage rod 31, when the locking lock heads 13 slide upwards, a cam disc 32 of the auxiliary device is driven to rotate, a push rod 34 is pushed, and when the locking lock heads 13 are inserted into the locking holes of the door frame 02, the door leaf lock catch 22 is disengaged when the door leaf 01 is locked in place.
In the initial stage of the upward sliding of the locking lock 13 linked with the hand wheel of the rotary locking mechanism 1, the cam disc 32 rotates around the rotating shaft on the door lock seat 21 under the drive of the linkage rod 31, the door lock 22 and the bump button 23 are tightly buckled due to the elastic force of the sealing rubber strip 04, the push rod 34 is acted by the reactive force of the door lock 22 to push the cam disc 32 backward, and the buffer spring 33 is compressed.
When the locking head 13 slides upwards to insert into the middle and rear section of the locking hole, the door leaf 01 is slowly locked by the sliding of the wedge-shaped locking head into the locking hole, so that the door leaf lock catch 22 and the bump catch 23 of the auxiliary device are released, and the door leaf lock catch 22 is completely opened under the action of the buffer spring 33 and the push rod 34 and is buckled by the pawl 41 on the door leaf lock catch seat 21.
When the door leaf 01 is opened, the hand wheel of the locking mechanism 1 is rotated to enable the linked locking head 13 to slide out of the locking hole, the cam disc 32 is reset under the drive of the linkage rod 31, and at the moment, the door leaf lock 22 of the auxiliary device is still buckled by the pawl 41 and is in a fully opened state.
The operator pulls the handle of the door leaf 01 to slowly open the door leaf 01, and when the back of the pawl 41 on the door leaf lock seat 21 touches the reset block 43 on the door frame 02 in the initial stage of opening, the door leaf lock 22 is separated from the pawl 41, the door leaf lock 22 is released, the door leaf lock 22 is restored to the horizontal position, and the whole auxiliary device is restored to the initial state.
The door leaf 01 is opened in place, the jack is screwed out to support and fix the door leaf 01 firmly, and the complete peace fight conversion of the door leaf 01 is completed once.
The foregoing is merely exemplary of the present invention, and those skilled in the art should not be considered as limiting the invention, since modifications may be made in the specific embodiments and application scope of the invention in light of the teachings of the present invention.
