Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic locks, in particular to a door control electromagnetic lock structure which is convenient to install. Background Art
[0002] The design of electromagnetic lock (or magnetic lock) is the same as that of electromagnet, which uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force to tightly absorb the adsorption iron plate to achieve the effect of locking the door. As long as there is a small current, the electromagnetic lock will generate a huge magnetic force. The access control system that controls the power supply of the electromagnetic lock will cut off the power after the person is correctly identified. The electromagnetic lock loses its suction and the door can be opened. Different electric locks are used in the access control system, and the commonly used ones are electric bolt locks, electromagnetic locks, electric strikes and electric control locks.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-5 The utility model discloses a conveniently installed access control electromagnetic lock structure, comprising a lock body 1 and a lock core door frame fixing member 2, wherein an electromagnetic lock core 3 is arranged inside the lock body 1, and the electromagnetic lock core 3 is a push-pull electromagnetic lock, a fixing plate 11 is arranged on one side of the lock body 1, and a positioning pin 13 is movably sleeved inside the lock body 1, one end of which passes through the lock body 1 and is fixedly connected to one side of the fixing plate 11, and two arc-shaped adjustment holes 16 are symmetrically arranged inside the lock body 1, and the two arc-shaped adjustment holes 16 are respectively located on both sides of one end of the electromagnetic lock core 3, and the positioning pin 13 is close to the other end of the electromagnetic lock core 3, and two fixing pins 113 movably sleeved with the two arc-shaped adjustment holes 16 are fixedly arranged on one side of the fixing plate 11, and a screw 18 is also movably arranged inside the lock body 1, and an inclined plate 19 located on one side of the fixing pin 113 is threadedly sleeved on the screw 18.
[0026] Specifically, there are two screws 18, and the two screws 18 correspond to two fixing pins 113 respectively. The positioning pin 13 corresponds to the central axis of the electromagnetic lock core 3. A fixing seat 17 is fixedly arranged inside the lock body 1, and a limiting groove 171 is provided inside the fixing seat 17. The limiting groove 171 is used to limit the displacement of the inclined plate 19, so that when the screw 18 is rotated, the inclined plate 19 is prevented from rotating with the screw 18, so that the inclined plate 19 can only move horizontally left and right with the rotation of the screw 18. The positioning pin 13 corresponds to the central axis of the electromagnetic lock core 3, so that when the lock body 1 is adjusted, the lock body 1 and the electromagnetic lock core 3 are adjusted upward or downward with the positioning pin 13 as the center of the circle.
[0027] Specifically, the side of the inclined plate 19 away from the screw rod 18 is inclined and contacts one side of the fixing pin 113. One end of the inclined plate 19 passes through the limiting groove 171 and is provided with a baffle 191. Figure 4 The setting of the baffle 191 prevents the inclined plate 19 from being separated from the inner part of the limiting groove 171 when it moves to the left. Figure 5 The end of the screw rod 18 away from the fixing seat 17 is provided with a slot for connecting a screwdriver, and the screw rod 18 can be rotated by the screwdriver. One end of the screw rod 18 is connected to the fixing seat 17 through a bearing, so that when the screw rod 18 is rotated, the screw rod 18 will not move left or right. When the screw rod 18 is rotated, the inclined plate 19 is driven to move left or right according to the positive and negative rotation direction of the screw rod 18. Figure 4 When the inclined plate 19 moves to the right, the inclined surface of the inclined plate 19 contacts the fixing pin 113, so that the inclined plate 19 drives the lock body 1 and the arc-shaped limiting hole 2 15 and the arc-shaped limiting hole 14 to flip upward with the positioning pin 13 as the center. Before adjustment, it is necessary to rotate the other screw rod 18 to make the opposite action so that the other inclined plate 19 is out of contact with the fixing pin 113 on one side thereof, and there is enough adjustment space between the fixing pin 113, that is, when one of the screw rods 18 is rotated to drive the inclined plate 19 for adjustment, it is necessary to rotate the other screw rod 18 at the same time to make adjustment in the opposite direction of movement, so as to realize the angle adjustment of the lock body 1 and the electromagnetic lock core 3. After the adjustment is completed, the two inclined plates 19 are respectively in contact with the two fixing pins 113, so as to realize the fixation of the lock body 1.
[0028] Specifically, the lock body 1 is symmetrically provided with two arc-shaped limit holes 14 respectively located on both sides of the positioning pin 13, and one side of the fixing plate 11 is fixedly provided with two limit pins 111 respectively movably connected with the two arc-shaped limit holes 14, and the lock body 1 is symmetrically provided with two arc-shaped limit holes 15. The two arc-shaped limit holes 15 are respectively located on one side of the two arc-shaped adjustment holes 16, and one side of the fixing plate 11 is fixedly provided with two limit pins 112 respectively movably connected with the two arc-shaped limit holes 15. The limit pin 111 and the limit pin 112 are both T-shaped, and the limit pin 111 and the limit pin 112 are respectively used to limit the four corners of the lock body 1, thereby ensuring the fitting stability of the lock body 1 and the fixing plate 11.
[0029] Specifically, one end of the screw rod 18 is rotatably disposed inside the fixing seat 17 via a bearing, and the other end of the screw rod 18 extends to one side of the lock body 1 .
[0030] Specifically, the centers of the arc-shaped adjustment hole 16 , the first arc-shaped limiting hole 14 , and the second arc-shaped limiting hole 15 are all consistent with the center of the positioning pin 13 .
[0031] Specifically, the top and bottom of the fixing plate 11 are both provided with a connecting ear 12, and one side of the lock core door frame fixing piece 2 is provided with a lock tongue hole 21 matching one end of the electromagnetic lock core 3, and the top and bottom of the lock core door frame fixing piece 2 are both provided with a connecting ear 22. The lock core door frame fixing piece 2 is screwed to the door frame through the connecting ear 22, and the fixing plate 11 is fixed to the door body through the connecting ear 12. When the fixing plate 11 is installed, if one end of the electromagnetic lock core 3 is offset from the lock tongue hole 21, the two screws 18 can be rotated to adjust the angle of the lock body 1 and the electromagnetic lock core 3.
[0032] To sum up, this easy-to-install access control electromagnetic lock structure, when the lock body 1 has an angular deviation with the lock core door frame fixing part 2 after installation, the angle of the lock body 1 can be adjusted by rotating the screw 18, without the need to reinstall the fixing plate 11, thereby ensuring the installation efficiency and avoiding the need to replace the door body. The setting of the arc-shaped limit hole 14 and the arc-shaped limit hole 2 15 ensures the fitting stability between the lock body 1 and the fixing plate 11, thereby meeting the user's usage requirements.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
