[0023] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0024] Combination Figures 1 to 13The utility model includes a shell 18, in which a cylinder 1 placed on the left and right is fixed, a through hole 19 is provided below the right side plate of the shell 18, and a rotating cylinder 2 is rotatably installed in the cavity of the cylinder 1;
[0025] There is a disc 3 in the cavity of the rotating drum 2 which can move left and right. The outer edge of the disc 3 moves in close contact with the inner edge of the rotating drum 2. The disc 3 is always subjected to a rightward extrusion force. There is a baffle 4 on the outside of the cylinder 1. The disc 3 and the baffle 4 are fixedly connected together.
[0026] In the initial state, the disc 3 is placed on the right side of the drum 2 under the extrusion force, and the baffle plate 4 is fitted together with the inner side of the through hole 19 on the shell 18; when the disc 3 moves to the left for a certain distance, the drum 2 can rotate on the cylinder 1 with the disc 3 and the baffle plate 4, and the drum 2 can be fixed after rotating a certain angle.
[0027] The lower end surface of the cylinder 1 is provided with a first rectangular groove 5 in the left-right direction, and the rotating cylinder 2 is provided with a second rectangular groove 6 corresponding to the first rectangular groove 5 and having the same size;
[0028] The disc 3 and the baffle 4 are connected together via a rectangular plate 9, and the rectangular plate 9 is placed in the rectangular cavity of the first rectangular groove 5 and the second rectangular groove 6;
[0029] An annular groove 10 is formed on the left side of the cylinder 1, the annular groove 10 is connected to the cavity of the cylinder 1, and one end of the annular groove 10 is connected to the first rectangular groove 5;
[0030] When the disc 3 moves a certain distance to the left, the rectangular plate 9 is placed in the position of the annular groove 10. At this time, when the drum 2 rotates, the rectangular plate 9 will rotate in the annular groove 10, and at the same time drive the disc 3 and the baffle plate 4 to rotate together.
[0031] The second rectangular groove 6 has a rectangular frame 11 fixed on the inner edge of the drum 2, the rectangular cavity of the rectangular frame 11 is consistent with the rectangular strip, and the rectangular strip is placed in the rectangular cavity of the rectangular frame 11, and the disc 3 has two grooves placed on both sides of the rectangular plate 9, and the front and rear side plates of the rectangular frame 11 are placed in the grooves;
[0032] The arrangement of the rectangular frame 11 can greatly improve the stability of the disc 3 and the baffle 4 .
[0033] The utility model also includes a cylinder 7, the cylinder 7 is consistent with the cavity diameter of the rotating drum 2, a handle is provided on one side of the cylinder 7, a blind hole is provided on the outer edge surface of the cylinder 7, a limit rod 13 is inserted in the blind hole, the limit rod 13 can slide in and out of the blind hole, the outer end of the limit rod 13 is a spherical structure, a compression spring is provided in the blind hole, one end of the compression spring is fixed to the bottom surface of the blind hole, and the other end of the compression spring is fixed to the limit rod 13; a third rectangular groove 12 is provided on the cylinder 7;
[0034] The rotating drum 2 has a circular hole 14;
[0035] When the cylinder 7 is inserted into the cavity of the rotating drum 2 so that the outer end of the limiting rod 13 is placed in the circular hole 14 , the cylinder 7 pushes the disc 3 so that the rectangular plate 9 is placed in the position of the annular groove 10 .
[0036] The cylinder 1 is provided with a circular groove 15 , and the circular groove 15 and the circular hole 14 are arranged in the same plane.
[0037] The left end of the cavity of the rotating drum 2 is a solid structure. There is a blind hole at the center of the left end surface of the cavity of the rotating drum 2. A push rod 8 that can move left and right is inserted in the blind hole. A compression spring is installed in the blind hole. The compression spring gives the disc 3 a squeezing force that always goes to the right through the push rod 8.
[0038] The right end of the push rod 8 is provided with a rectangular disk, which increases the contact area between the push rod 8 and the disk 3 and improves the stability of the disk 3 when it moves.
[0039] The utility model installs a shell 18 on the outer side of the cabinet door lock 17, so that the lock 17 is placed in the shell 18. The shell 18 can be rectangular or circular, and is rectangular in this solution. The through hole 19 on the shell 18 corresponds to the lock 17 front and back, and the key can open the lock 17 through the through hole 19.
[0040] The initial state of the utility model when in use is that the disc 3 is placed on the right side of the drum 2 under the extrusion force of the push rod 8, and at the same time the baffle 4 blocks the through hole 19 on the right side plate of the housing 18, ensuring that the lock 17 is sealed in the housing 18;
[0041] When the lock 17 needs to be opened, the cylinder 7 is inserted into the cavity of the rotating drum 2 through the handle, so that the disc 3 moves to the left, and at the same time the rectangular frame 11 is placed in the third rectangular groove 12 on the cylinder 7, and the outer end of the limiting rod 13 on the cylinder 7 is placed in the circular hole 14, so that the rectangular plate 9 is placed in the position of the annular groove 10, and then the cylinder 7 is rotated through the handle, and the cylinder 7 drives the rotating drum 2 to rotate through the limiting rod 13 and the circular hole 14, the rectangular frame 11 and the third rectangular groove 12. Since the rectangular plate 9 can rotate in the annular groove 10, the rotating drum 2 can rotate with the disc 3 and the baffle plate 4, so that the baffle plate 4 opens the through hole 19 on the shell 18. When the limiting rod 13 rotates to the position of the circular groove 15, the outer end of the limiting rod 13 can be placed in the circular groove 15, so that the rotating drum 2 can be fixed, and then the key is inserted into the lock 17 to open the cabinet door 16;
[0042] When the cabinet door 16 needs to be closed, the cylinder 7 is rotated in the opposite direction by the handle to disengage the limit rod 13 on the cylinder 7 from the circular groove 15. Then, the cylinder 7 continues to rotate with the rotating drum 2 in the cylinder body 1 until the rectangular plate 9 rotates into the first rectangular groove 5. Then, the cylinder 7 is pulled outward by the handle to disengage the limit rod 13 from the circular hole 14. After disengagement, the disc 3 moves to the right under the action of the push rod 8, and at the same time, the baffle plate 4 is re-attached to the through hole 19 of the shell 18 to block the through hole 19.
[0043] The utility model adopts a structure in which the baffle plate 4 can swing after axial sliding, and the through hole 19 at the front end of the lock 17 is opened and closed, so as to isolate the lock 17 from external rainwater and prevent the lock 17 from rusting.
[0044] The cylinder 7 extends into the drum 2 so that the rectangular plate 9 can just move to the position of the annular groove 10, which makes it impossible for non-staff to determine how far the rectangular plate 9 slides to reach the annular groove 10, and the lock 17 cannot be leaked, thereby preventing non-staff from damaging the lock 17.
