Detailed implementation manners

[0029] The following further elaborates in detail on the detailed implementation manners of the present utility model in conjunction with the Figures 1-6 accompanying drawings.

[0030] As Figures 1-6 shown, a concrete door leaf locking shaft sleeve includes a first door lock shaft sleeve 1. A first through groove 2 is provided on the left side of the door lock shaft sleeve, and the opening of the first through groove 2 faces left.

[0031] It further includes a swingable second door lock shaft sleeve 3. A second through groove 4 is provided at the lower end of the second door lock shaft sleeve 3, and the opening of the second through groove 4 faces downwards. The first through groove 2 and the second through groove 4 cooperate to form a structure for fixing the lock core.

[0032] In this device, the first door lock shaft sleeve 1 can be of a square structure. The opening of the first through groove 2 faces left, the right side of the first through groove 2 is of an arc-shaped structure, the opening of the second through groove 4 faces downwards, and the upper end of the second through groove 4 is also set to be of an arc-shaped structure. The lock core is set to be of a columnar structure. As Figure 1 shown, when the lock core moves towards the right, it first enters the first through groove 2, then contacts the left side of the second door lock shaft sleeve 3, pushing the second door lock shaft sleeve 3 to swing upwards. Then when the second door lock shaft sleeve 3 no longer blocks the lock core, the lock core slides towards the right side of the first through groove 2, and at the same time the second door lock shaft sleeve 3 swings back. When the lock core moves to the rightmost side of the first through groove 2, the second through groove 4 also catches the lock core, and at this time the lock core is locked. Without external force driving, the lock core is stuck.

[0033] At the same time, we can set a stop head on the first door lock shaft sleeve 1 to block the position where the second door lock shaft sleeve 3 swings downwards.

[0034] When it is necessary to release the cooperation between the two, drive the second door lock shaft sleeve 3 to swing upward, and at the same time pull the lock core to move to the left. The two cooperate to complete the entire opening.

[0035] It also includes a support plate 5, and the second door lock shaft sleeve 3 is hinged and fixed to the support plate 5.

[0036] In this device, the second door lock shaft sleeve 3 includes a horizontal plate, and the right side of the horizontal plate is hinged and fixed to the support plate 5.

[0037] The left side of the second door lock shaft sleeve 3 is of an arc-shaped or inclined structure.

[0038] An arc-shaped plate or an inclined plate is connected to the left side of the horizontal plate. In this way, when the lock core moves to the right, it will push the second door lock shaft sleeve 3 to swing upward, so that the door lock can enter the rightmost side of the first through groove 2.

[0039] The upper end of the left side of the second door lock shaft sleeve 3 is located on the left side of the lower end on the left.

[0040] The second door lock shaft sleeve 3 is set to be inclined downward, and the upper end is located on the left side, mainly to enable the lock core to push the second door lock shaft sleeve 3 to swing upward during movement.

[0041] An extension plate 6 is fixed to the right side of the second door lock shaft sleeve 3, and a stop lever 7 is hinged to the first door lock shaft sleeve 1. The swing of the stop lever 7 is a structure that restricts the extension plate 6 from swinging to the left.

[0042] In this device, the stop lever 7 swings to contact the extension plate 6. At this time, the stop lever 7 blocks the extension plate 6 from swinging to the left. At this time, the entire structure is locked, and the cooperation between the door lock and the first through groove 2 and the second through groove 4 cannot be released.

[0043] A vertical rod 8 is fixed to the lower end of the stop lever 7, and the contact between the vertical rod 8 and the extension plate 6 is a structure that blocks the extension plate 6.

[0044] The vertical rod 8 is of a columnar structure, and a part of the vertical rod 8 and the extension plate 6 is in the same space. At this time, the column can block the movement of the extension plate 6.

[0045] An avoidance groove 9 is formed on the extension plate 6, and the extension plate 6 can pass through the vertical rod 8 through the avoidance groove 9 when swinging.

[0046] In this device, a torsion spring is provided at the hinge joint of the stop lever 7 and the first door lock shaft sleeve 1. One end of the torsion spring is fixed to the stop lever 7, and the other end of the torsion spring is fixedly connected to the first door lock shaft sleeve 1. Under the action of the torsion spring, the stop lever 7 is in a certain fixed position initially. At this time, when the extension plate 6 swings to the left, the avoidance groove 9 will pass through the vertical rod 8, so as not to interfere with the pull rod at all.

[0047] After the extension plate 6 swings back into place, the shift lever 7 will swing at this time. The shift lever 7 no longer swings through the avoidance groove 9 and directly contacts the extension plate 6, thereby limiting the extension plate 6.

[0048] The shift lever 7 is of a V-shaped structure, and the middle part of the shift lever 7 is hinged and fixed to the first door lock bushing 1;

[0049] A horizontally sliding slider 10 is provided on the first door lock bushing 1. A first connecting rod 11 is hinged to the slider 10, and the right end of the first connecting rod 11 is hinged and fixed to the left side of the shift lever 7.

[0050] The slider 10, the first connecting rod 11 and the shift lever 7 together form a crank-slider 10 structure. The slider 10 moves horizontally, thereby driving the shift lever 7 to swing.

[0051] A horizontally sliding push rod 12 is provided on the first door lock bushing 1. The left side of the push rod 12 is located in the first through groove 2, and the right side of the push rod 12 can slide to contact the slider 10 and push the slider 10 to slide to the right.

[0052] When the lock core slides to the right side of the first through groove 2, it will push the push rod 12 to move to the right. The push rod 12 moves to the right to contact the slider 10, pushing the slider 10 to move to the right, and then realizing the swing of the shift lever 7.

[0053] A vertical plate 13 is fixed on the first door lock bushing 1. The push rod 12 slidably penetrates through the vertical plate 13. A reinforcing plate 14 is fixed in the middle of the push rod 12. A tension spring 15 is sleeved on the outer circumference of the push rod 12. One end of the tension spring 15 is fixedly connected to the vertical plate 13, and the other end of the tension spring 15 is fixedly connected to the reinforcing plate 14.

[0054] A blocking plate is fixed on the push rod 12. The blocking plate is located on the right side of the vertical plate 13. The blocking plate contacts the vertical plate 13 to form a structure that restricts the push rod 12 from moving to the left.

[0055] The setting of the vertical plate 13 provides a supporting force and at the same time plays a guiding role in the sliding of the push rod 12. The tension spring 15 pulls the push rod 12 to slide to the left, so that in the initial state, the push rod 12 is located in the first through groove 2, and at the same time, under the action of the tension spring 15, the push rod 12 is prevented from contacting the slider 10.

[0056] Under the action of the blocking plate, the position of the push rod 12 entering the first through groove 2 is restricted.

[0057] A horizontal slideway 16 and a vertical slideway 17 are provided on the first door lock bushing 1. The horizontal slideway 16 and the vertical slideway 17 intersect to form an L-shaped slideway. The slider 10 slides in the L-shaped slideway. When the slider 10 slides to the rightmost position of the horizontal slide, the shift lever 7 blocks the extension plate 6 from swinging to the left;

[0058] When the slider 10 slides to the uppermost end of the vertical slideway 17, the expansion plate 6 can pass through the stop lever 7 when swinging to the left.

[0059] In this device, when the lock core is in contact with the right side of the first through groove 2, at this time, the push rod 12 pushes the slider 10 to move to the rightmost side of the horizontal slideway 16, and the stop lever 7 blocks the expansion plate 6 from swinging to the left;

[0060] At this time, a partition is used to separate the horizontal slideway 16 and the vertical slideway 17, and the slider 10 cannot enter the vertical slide. When it is necessary to release the cooperation between the lock core and the first through groove 2 and the second through groove 4, the partition is opened, and then the lower end of the stop lever 7 is driven to swing to the left. At this time, the slider 10 enters the vertical slideway 17 and slides upward. After sliding to the limit position, the stop lever 7 is fixed. The fixing of the stop lever 7 can be completed by using a pin or the like. Then the second door lock sleeve 3 can be driven to swing, pulling the lock core to slide to the left to complete the release of the cooperation among the three.

[0061] Then the fixing of the stop lever 7 is released and it returns to its original position. At this time, the push rod 12 also automatically returns to its original position under the action of the tension spring 15.

[0062] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
