Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door locks, in particular to a U-shaped door lock. Background Art
[0002] In real life, U-shaped door locks are very common, such as in office buildings and school office buildings. Figure 1 As shown, it mainly includes a U-shaped lock rod 1 and a lock member 2 matched therewith. The cross section of the lock rod 1 is circular. The principle of the lock member 2 being locked on the lock rod 1 can refer to the principle of the lock bolt being locked on the U-shaped lock body in the Chinese patent (application number: CN201520063487.8). When locking the two door bodies X, Figure 1-2 As shown, a vertical door handle X-1 is provided on the side where the two door bodies X are close to each other, and two horizontal connecting rods X-2 are fixed between the door handle X-1 and the door body X.
[0003] When the locker can only lock the door body X with one hand (for example, holding a child or holding an item that is inconvenient to put on the ground in one hand), the lock rod 1 is first inserted into the two connecting rods X-2 on the same horizontal line of the two door bodies X with one hand, and then the lock member 2 is put on the lock rod 1, and the lock member 2 is pushed to move toward the closed end of the lock rod 1. Figure 1 However, there is no blocking structure designed on the U-shaped door lock, so it is possible that the lock rod 1 moves together with the lock element 2, resulting in Figure 1 In the situation, until the lock member 2 is against the adjacent door handle X-1, the lock of the lock member 2 on the lock rod 1 is not completed. Therefore, it is necessary for us to improve the U-shaped door lock of the prior art. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a U-shaped door lock, which solves the problems mentioned in the background technology.
[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:
[0006] A U-shaped door lock comprises a U-shaped locking rod and a locking piece matched therewith, wherein the cross section of the locking rod is circular.
[0007] Compared with the prior art, the most important design of the utility model is that a blocking structure is installed on both side rods of the locking rod, and the blocking structure includes a blocking member installed on the locking rod, and the blocking member extends forward of the locking rod. In order to realize the versatility of the blocking member, the blocking member is a hook.
[0008] In order to adjust the position of the hook on the locking rod, an adjusting member for adjusting the position of the blocking member is provided on the locking rod. The adjusting member is an adjusting ring installed on the locking rod, and the mounting end of the hook is fixed at the lowest point of the adjusting ring. An external thread is provided on the surface of the locking rod, and an internal thread is provided on the inner ring surface of the adjusting ring to enable its thread to cooperate with that on the locking rod.
[0009] Compared with the prior art, the utility model has the following beneficial effects: the locking rod is inserted into the two connecting rods corresponding to the two door bodies, one side of the blocking member is against the door handle of one of the door bodies, and the locking member is directly pushed to move along the locking rod, so that locking can be achieved with one hand, making the entire U-shaped door lock more convenient to use.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0018] like Figure 3 As shown, the utility model provides a U-shaped door lock, including a U-shaped locking rod 1 and a locking member 2 matched therewith, the locking rod 1 has a circular cross section, and the above structure is the same as the U-shaped door lock in the prior art.
[0019] like Figure 3-6As shown, compared with the prior art, the most important design of the utility model is: a blocking structure is installed on the two side rods of the locking rod 1, and the blocking structure includes a blocking member 3 installed on the locking rod 1, and the blocking member 3 extends forward of the locking rod 1. In order to realize the versatility of the blocking member 3, the blocking member 3 is a hook. When there is no one in the room or the delivery staff is not wanted to enter the room, the delivery staff can hang the takeaway packaging bag on the hook. In this way, the hook can not only block the locking rod 1 from moving left and right, but also play the role of hanging the takeaway, serving two purposes at one stroke and having a certain degree of creativity.
[0020] like Figure 3-4 As shown, when in use, the lock rod 1 is inserted into the two connecting rods X-2 on the same horizontal line of the two door bodies X, and the two hooks can be located between the two door handles X-1. It should be noted here that the length of the connecting rod X-2 should be greater than the width of the hook, so that the hook can also be inserted between the two door handles X-1. Turn the hook so that it extends from the rear side of the door handle X-1, and then push the lock piece 2 to move along the lock rod 1 with one hand. If the lock rod 1 is moved together, and then the hook is driven to move until the hook rests on the door handle X-1, the lock rod 1 can stop moving. Before locking, the lock piece 2 can also be directly rotated by one hand to move it on the lock rod 1 until the hook rests on the door handle X-1. When the lock rod 1 is blocked, continue to push the lock piece 2 to move along the lock rod 1 until the locking is completed.
[0021] like Figure 5-6 As shown, in order to adjust the position of the hook on the locking rod 1, an adjusting member 4 for adjusting the position of the blocking member 3 is provided on the locking rod 1. The adjusting member 4 is an adjusting ring installed on the locking rod 1, and the mounting end of the hook is fixed at the lowest point of the adjusting ring. An external thread is provided on the surface of the locking rod 1, and an internal thread is provided on the inner ring surface of the adjusting ring so that its thread cooperates with that on the locking rod 1. By rotating the hook, the adjusting ring is driven to rotate along the locking rod 1 to achieve movement. In this way, the distance from the hook to the free end of the locking rod 1 can be adjusted to facilitate the use of two door handles X-1 with different spacings on different door bodies X.
[0022] Finally, the most important contribution of the present invention is that the locking rod 1 is inserted into the two connecting rods X-2 corresponding to the two door bodies X, and one side of the blocking member 3 is against the door handle X-1 of one of the door bodies X, directly pushing the locking member 2 to move along the locking rod 1, realizing one-handed locking, making the entire U-shaped door lock more convenient to use.
[0023] 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.
