[0013] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the preferred implementation manners of the present utility model will be described below in conjunction with specific embodiments. However, it should be understood that these descriptions are only for further explaining the features and advantages of the present utility model, rather than limiting the patent requirements of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0014] The present utility model will be further described below in conjunction with the accompanying drawings and preferred embodiments.
[0015] Embodiment 1
[0016] Refer to Figure 1 As shown, a lock involved in this embodiment includes a lock member 100 provided on a sliding door (not shown) and a fastener 200 provided on a door frame (not shown). The lock member 100 moves in a direction close to or away from the fastener 200. The lock member 100 includes a first back plate 101, and a lock plate 102 extending towards the fastener is rotatably connected to the first back plate 101. A lock groove 103 with an upward notch is provided at one end of the lock plate 102 close to the fastener. A retaining post 104 for restricting rotation is provided above the lock plate 102, and the retaining post 104 is provided on the first back plate 101. A tension spring 105 with one end connected to the first back plate and the other end connected to the lock plate is also provided above the lock plate 102. A step ring 106 is provided below the lock plate 102, and a rope 107 is connected between the step ring 106 and the lock plate 102. The fastener 200 includes a second back plate 201, and a lock post 202 extending forward is provided on the second back plate 201. The lock post 202 is arranged in the lock groove 103.
[0017] Furthermore, the first back plate 101 is fixedly connected to the sliding door; the second back plate 201 is fixedly connected to the door frame.
[0018] In this implementation manner, when the lock is in the closed state, the lock post 202 is located in the lock groove 103, and the lock member 100 cannot be moved away from the fastener 200, resulting in the sliding door being unable to be opened. When it is necessary to unlock the lock, one foot can be inserted into the step ring 106, the toes gently press against the sliding door, and the foot is pressed down, causing the step ring 106 to pull down the rope 107. The lock plate 102 rotates downward relative to the first back plate 101, and the tension spring 105 is stretched. The lock post 202 gradually separates from the lock groove 103. At this time, by laterally moving the toes gently pressing against the sliding door or using one hand for assistance, the sliding door can be moved away from the door frame to open the door.
[0019] Among them, through the setting of the retaining post 104, it is used for the upper limit of the lock plate 102 after reset.
[0020] Among them, through the setting of the tension spring 105, it is used for the automatic reset of the lock plate 102.
[0021] Embodiment 2
[0022] See Figure 1 As shown, a lock involved in this embodiment is further set, on the basis of Embodiment 1, that a chamfered portion 108 provided on the lock plate is provided on one side of the lock groove 103 facing the fastener.
[0023] In this embodiment, through the setting of the chamfered portion 108, when the lock plate 102 moves close to the lock post 202, the lock post 202 will laterally push the lock plate 102 along the chamfered portion 108, causing the lock post 202 to quickly enter the lock groove 103, achieving the effect that the lock can be quickly closed by gently pushing the sliding door.
[0024] Embodiment 3
[0025] See Figure 1 As shown, a lock involved in this embodiment is further set, on the basis of Embodiment 1, that rope loops 300 arranged at intervals in the vertical direction are sleeved on the rope 107, and the rope loops 300 are fixed on the sliding door.
[0026] In this embodiment, through the setting of the rope 107, it is used for the limiting effect on the rope 107 extending downward.
[0027] Embodiment 4
[0028] See Figure 1 As shown, a lock involved in this embodiment is further set, on the basis of Embodiment 1, that an avoidance notch 109 for embedding the tension spring is provided on the lock plate 102.
[0029] In this embodiment, through the opening of the avoidance notch 109, it is used for the installation of the tension spring 105.
[0030] The lock involved in the present utility model has the characteristics of simple structure and convenient opening and closing, and can be closed by gently pushing, and can also be opened without manual control. The overall function is perfect and the practicability is strong.
