Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1 to 4, the anti-riot lock device mounted on a door panel 100 includes a lock body 101, an inner handle 102, an inner panel 103, an outer handle 104, an outer panel 105, an inner square bar 1 and an outer square bar 2, wherein the lock body 101, the inner handle 102, the inner panel 103, the outer handle 104 and the outer panel 105 are mounted on the door panel 100 in a conventional mounting manner.
As shown in fig. 5 to 12, an inner connecting member 3 is fixedly installed and connected to the inner handle 102, and the inner connecting member 3 is provided with a shaft hole 31. The first end of the inner rod 1 is connected to the inner connecting member 3, specifically, the shaft hole 31 is a square hole, the inner rod 1 is a square column, the inner rod 1 is inserted into the shaft hole 31, the inner rod 1 can move axially in the shaft hole 31, and the first end of the inner rod is fixed in the shaft hole 31 in the circumferential direction. The shaft hole 31 is provided with a first spring 4 between the inner connecting piece 3 and the inner square rod 1, one end of the first spring 4 is abutted against the bottom of the shaft hole 31, and the other end is abutted against the end face of the first end of the inner square rod 1.
A shaft sleeve 5 is arranged in the lock body 101, the shaft sleeve 5 is provided with an insertion hole 51 penetrating through the front end surface and the rear end surface, and the second end of the inner square rod 1 is inserted in the insertion hole 51 from the rear end of the shaft sleeve 5.
The first end of the square outside rod 2 is inserted into the insertion hole 51 from the front end of the shaft sleeve 5, the outer handle 104 is provided with an inner hole, the second end of the square outside rod 2 can be directly connected with the inner hole in a matched manner, preferably, the second end face of the square outside rod 2 is provided with a threaded hole 21 along the axial direction of the square outside rod 2, the threaded hole 21 is screwed with the adjusting rod 6, the adjusting rod 6 is provided with a rod cap 61 which is consistent with the peripheral shape of the square outside rod 2, and the rod cap 61 of the adjusting rod 6 is clamped in the inner hole, so that the square outside rod 2 can be connected with the inner hole depth on the handle on the outer panel 105 in a matched manner according to the situation to adapt to different thicknesses of the door panels 100.
Therefore, the shaft sleeve 5 can be rotated by rotating the inner handle 102 to drive the inner square rod 1 or rotating the outer handle 104 to rotate the outer square rod 2, so that the shaft sleeve 5 can drive the mechanism in the lock body 101 to realize the locking or unlocking function of the lock body 101.
Because the first spring 4 is arranged between the first end of the inner square rod 1 and the inner connecting piece 3, the inner square rod 1 keeps the trend that the second end of the inner square rod continuously moves towards the direction of the plug hole 51 under the action of the first spring 4, and the side surface of the inner square rod 1 close to the second end is provided with the locking groove 11; the shaft sleeve 5 is also provided with a locking pin 71 and a second spring 72, specifically, the side surface of the shaft sleeve 5 is provided with a stepped hole 52, the central axis of which is vertically intersected with the central axis of the plug hole 51 and is communicated with the plug hole 51; the locking pin 71 has a locking cap, the locking pin 71 extending into the smaller hole of the stepped bore 52 and the locking cap being in the larger hole of the stepped bore 52; the end cap of the stepped hole 52 far from the connection with the plug hole 51 is provided with a sealing sheet 73, the second spring 72 falls into the larger hole of the stepped hole 52, and one end of the second spring abuts against the sealing sheet 73 and the other end abuts against the lock cap. Two opposite side surfaces of the inner square rod 1 close to the second end are respectively provided with a locking groove 11; the stepped holes 52 are provided on opposite side surfaces of the sleeve 5 corresponding to the locking grooves 11 in two in total, and each stepped hole 52 is provided with the locking pin 71 and the second spring 72.
Under the action of the second spring 72, the locking pin 71 keeps the trend that the first end of the locking pin continuously moves towards the insertion hole 51; when the first end of the outer rod 2 is pulled out of the insertion hole 51 (i.e., the outer panel 105 and the outer handle 104 are forcibly removed, the outer rod 2 is easily removed), the inner rod 1 continues to move toward the insertion hole 51 by the first spring 4 until the first end of the locking pin 71 is inserted into the locking groove 11 to be prevented from retreating. At this time, if a tool is used outside, the sleeve 5 cannot be rotated, and thus the effect of preventing the violent unlocking can be achieved.
In order to improve the anti-riot level, as shown in fig. 9 and 10, the side surface of the inner square rod 1 near the second end is provided with an anti-rotation protrusion 12, the rear end surface of the shaft sleeve 5 is provided with an anti-rotation groove 53, the lock body 101 is provided with an anti-rotation groove 107 corresponding to the position where the shaft sleeve 5 is provided with the anti-rotation groove 53, and when the first end of the locking pin 71 is inserted into the locking groove 11 and the inner square rod 1 is prevented from retreating, the anti-rotation protrusion 12 falls into the anti-rotation groove 53 and the anti-rotation groove 107 at the same time to prevent the inner square rod 1 from rotating around the central axis thereof. Thereby further preventing the shaft sleeve 5 from being twisted by external force to avoid being unlocked violently.
Considering that the inner panel 103 falls off first due to accident, and the inner square bar 1 is pushed forward, and finally loses the function of the first spring 4, the above structure can be further modified as shown in fig. 11, there is a third spring 8 sleeved on the inner square bar 1 from the first end of the inner square bar 1, one end of the third spring 8 abuts against the rotation-preventing protrusion 12 and the other end abuts against the inner panel 103, under the function of the third spring 8, the inner square bar 1 keeps the trend that the second end of the inner square bar 1 moves continuously towards the direction of the plug hole 51.
In order to improve the level of explosion-proof, when the first end of the locking pin 71 is inserted into the locking groove 11 and the inner square bar 1 is prevented from retreating, the end surface of the first end of the locking pin 71 can be just flush with the front end surface of the boss 5. That is, the shaft hole 31 is completely blocked by the inner square rod 1, and the external tool cannot be forcibly unlocked.
In order to insert the first end of the locking pin 71 into the locking groove 11 and prevent the locking pin 71 from retreating, the locking pin 71 is reset so that the outer rod 2 can be inserted into the shaft hole 31 again, a groove 13 communicated with the locking groove 11 can be further arranged on the side surface of the inner rod 1 where the locking groove 11 is arranged, and the groove 13 is arranged from the locking groove 11 to axially extend towards the first end of the inner rod 1; when the first end of the locking pin 71 is inserted into the locking groove 11, a gap is formed between the end surface of the locking pin 71 facing the locking groove 11 and the bottom surface of the locking groove 11, and a user can insert the small iron wire 106 into the locking groove 11 through the groove 13 from one side of the inner square bar 1 into the gap, so that the locking pin 71 can be reset against the action of the second spring 72, the inner square bar 1 is retreated from the shaft hole 31, and thus, the outer square bar 2 can be reinserted into the shaft hole 31. In order to facilitate the entry of the small wire 106 (shown in broken lines in fig. 12) into the locking groove 11 via the groove 13 and to facilitate the action of the small wire 106 on the locking pin 71, the bottom surface of the groove 13 is preferably provided with a curved surface.
