DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0022] Example 1

[0023] like Figures 1 to 5 As shown, the U-shaped lock of this embodiment includes a lock rod 1, a lock head 2, a first support block 3 and a pop-up mechanism 4. The lock rod 1 is U-shaped, with lock hooks 11 at both ends. The left side of the lock head 2 is provided with a lock hole 21, and the right side is provided with a key hole (not shown). The first support block 3 and the lock head 2 are respectively installed on the vertical rods 5 of the two doors. The right side of the lock rod 1 passes through the first support block 3 horizontally, and the lock hook 11 is engaged in the lock hole 21. The pop-up mechanism 4 is installed on the first support block 3, and its telescopic end is connected to the left end of the lock rod 1. When unlocking, the lock hook 11 is separated from the lock hole 21, and the pop-up mechanism 4 drives the lock rod 1 to slide to the left. Among them, a lock core is provided in the lock head 2, which is a commonly used structure. When locking, the lock rod 1 slides to the right on the first support block 3 until the lock hook 11 enters and engages in the lock hole 21. At this time, the lock rod 1 drives the telescopic end of the pop-up mechanism 4 to move to the right, so that the telescopic end of the pop-up mechanism 4 is in a compressed state; when unlocking, the key is inserted into the keyhole and rotated, the lock hook 11 is separated from the lock hole 21, and the telescopic end of the pop-up mechanism 4 pushes the lock rod 1 to move to the left on the first support block 3 under the action of the restoring force, so that the lock rod 1 is automatically ejected. The U-shaped lock of this embodiment saves the action of manually pulling the lock rod when unlocking, which can effectively improve the efficiency of unlocking and opening the door; at the same time, the lock rod is embedded in the vertical rod of the door through the first support block, so that the lock rod and the vertical rod are combined into one, so that the lock rod becomes a part of the door, and the lock rod slides on the first support block without being taken out, avoiding the collision of the lock rod with the door surface, vertical rod, etc., which is convenient and practical and ensures safety.

[0024] In this embodiment, the pop-up mechanism 4 includes a support seat 41, a telescopic rod 42 and a spring 43. The support seat 41 is provided with a sliding hole 44. The support seat 41 is transversely fixed on the first support block 3. The telescopic rod 42 is slidably arranged in the sliding hole 44 of the support seat 41, and its front end is connected to the left end of the locking rod 1. The spring 43 is placed in the support seat 41, one end of which is fixed on the inner bottom of the sliding hole 44, and the other end of which is pressed on the rear end of the telescopic rod 42. When the U-shaped lock is locked, the locking rod 1 drives the telescopic rod 42 to slide to the right and compress the spring 43; when the U-shaped lock is opened, the lock hook 11 leaves the lock hole 21, and the spring 43 pushes the telescopic rod 42 to slide to the left in the support seat 41 under the action of its own telescopic force, driving the locking rod 1 to slide to the left on the first support block 3, so as to realize automatic pop-up when locked. A clamping block 45 is disposed at the top of the sliding hole 44 , and a clamping ring 46 is disposed at the rear end of the telescopic rod 42 . The cooperation between the clamping block 45 and the clamping ring 46 can effectively prevent the telescopic rod 42 from detaching from the supporting seat 41 when sliding to the left.

[0025] In this embodiment, the first support block 3 is provided with two first through holes 31 and one mounting hole 32 which penetrate the support block transversely, the right end of the locking rod 1 passes through the two first through holes 31, the support seat 41 is installed in the mounting hole 32, and the mounting hole 32 is located in the middle of the two first through holes 31. Through the design of the two first through holes 31 and one mounting hole 32, the telescopic rod 42 is kept parallel to the upper and lower parts of the locking rod 1, so as to facilitate the sliding of the telescopic rod 42 on the support seat 41 and the sliding of the locking rod 1 on the first support block 3.

[0026] In this embodiment, the U-shaped lock also includes a second support block 6, which is installed on the vertical rod 5 of the door on the right side, and the lock head 2 is installed in the second support block 6. A second through hole 61 concentrically arranged with the lock hole 21 is provided on the left side of the second support block 6. The first support block 3 and the second support block 6 are located on the same horizontal line. The lock head 2 is installed in the second support block 6, which is convenient for the installation and fixation of the lock head 2 and the alignment of the lock head 2 with the lock rod 1. At the same time, the lock head 2 is embedded in the vertical rod 5 of the door through the second support block 6, so that the lock head 2 and the vertical rod 5 are combined into one, so that the lock head 2 becomes a part of the door. The lock head 2 does not need to be taken out from the second support block 6, which avoids the collision of the lock head with the door surface, vertical rod, etc., which is convenient, practical and safe.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
