Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of locking connection, in particular to a flange type angle lock. BACKGROUND

[0002] At present, most of the mainstream rental and lending LED displays on the market support plane splicing and multi-angle splicing, and multi-angle splicing requires the use of arc-shaped locks or flange type angle locks. Due to the working principle and structural precision problems, arc-shaped locks can only be used on boxes with larger point spacings. With the development of LED display screens, people have higher requirements for LED display screens, and larger point spacing LED display screens are no longer suitable for the rental market. Therefore, such arc-shaped locks have been eliminated. Most LED display screen manufacturers now choose flange type angle locks as standard accessories for rental LED display screens. The flange type angle can switch the angle of the box by simply rotating the lock core, which is convenient for building various types of inner arc, outer arc and plane display screens. Due to the precision problem of the flange type angle lock, it is more suitable for use in smaller point spacing rental LED display screens and is more popular with users.

[0043] When the angle lock is installed at the factory, the locked mechanism 1 and the locking mechanism 2 are designed to be less in material, so that the installation and replacement are more simple and convenient, the production and assembly cost is saved, and the problem that the flange type angle lock structure is relatively complex and the production and assembly are relatively difficult is solved.

[0044] Specifically, referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 2 , the locked mechanism 1 and the locking mechanism 2 are arranged at the edge of the display screen frame and are arranged at different sides of the display screen frame. The lock fixed plate 11 is in the shape of [clockwise rotation by ninety degrees, the lock fixed plate 11 comprises a fixed part 111 and a support part 112, the fixed part 111 is integrally formed with the support part 112, the fixed part 111 is located at both sides of the support part 112, and the fixed parts 111 at both sides of the support part 112 are in bolted fixed connection with the display screen frame. An accommodation space for accommodating the lock cylinder 12 is formed between the lock fixed plate 11 and the display screen frame.

[0045] Referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 2As shown, the lock cylinder 12 is composed of five lock cylinder surfaces 121, and the whole lock cylinder 12 is an irregular pentagon. The inclination angles of the five lock cylinder surfaces 121 of the lock cylinder 12 are different, and the inclination angles of the respective lock cylinder surfaces 121 are 0 degree, +3 degrees, -3 degrees, +6 degrees and -6 degrees respectively, and the top of each lock cylinder surface 121 is marked with a scale mark of the corresponding inclination angle for easy identification. The middle position of each lock cylinder surface 121 is provided with a lock cylinder hole 1211 for cooperating with the locking mechanism 2, and a second accommodating space is formed inside each lock cylinder surface 121 for cooperating with the locking mechanism 2, and the second accommodating space is in communication with the lock cylinder hole 1211.

[0046] Referring to the accompanying drawings Figure 2 and the accompanying drawings Figure 4 As shown, the lower part of the lock cylinder 12 is provided with a limiting ring 14, and the limiting ring 14 is fixed on the outer frame of the display screen. Five limiting grooves 141 are uniformly arranged on the limiting ring 14. Two accommodating grooves are arranged at the joint of the bottom of the two adjacent lock cylinder surfaces 121 of the lock cylinder 12, and the two accommodating grooves are oppositely arranged at the bottom of the lock cylinder 12. A rotating limiting piece 13 for cooperating with the lower limiting groove 141 is fixed in the accommodating groove. In this embodiment, the rotating limiting piece 13 is a ball plunger, which includes a plunger sleeve, a pressing spring and a ball head. The pressing spring is arranged in the plunger sleeve, one end of the plunger sleeve is connected with the bottom of the plunger sleeve, and the other end of the plunger sleeve is connected with the ball head.

[0047] When the lock cylinder 12 is rotated to the side of the lock cylinder surface 121 that needs to cooperate with the locking mechanism 2, the rotating limiting piece 13 at the bottom of the lock cylinder cooperates with the limiting ring 14. Whenever the lock cylinder 12 is rotated by a fixed angle to make one of the lock cylinder surfaces 121 face outward, the ball head of the rotating limiting piece 13 will extend out of the plunger sleeve and enter the limiting groove 141 to cooperate with the limiting groove 141. When the lock cylinder 12 is continuously rotated, the ball head is pressed into the plunger sleeve by the side wall of the limiting groove 141 until it enters the next limiting groove 141. Since there is no obstruction from the top surface of the limiting ring 14, the ball head will again extend out of the plunger sleeve under the action of the pressing spring and cooperate with the limiting groove 141. This step-by-step adjustment of the lock cylinder 12 can accurately position the lock cylinder 12, so that each rotation of the lock cylinder 12 can make the lock cylinder surface 121 be located at the appropriate position, facilitating the cooperation of the lock cylinder 12 with the locking mechanism 2. Moreover, the structure is simple, the operation is convenient, and the lock cylinder 12 needs to overcome the damping when it is rotated, which can effectively avoid the phenomenon of deviation of the lock cylinder 12 after rotation due to accidental touch or shaking.
