DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-4 The utility model provides an embodiment: a sliding door handle type locking device, comprising a lock body bottom plate 1 for supporting, a fixed card seat 4 is arranged near the top of the side end surface of the lock body bottom plate 1,

[0023] A guide slot 5 is provided on the inner end surface of the fixed base 4, and a locking hole 7 is provided at the center of the inner end surface of the guide slot 5 and extends to the outside of the fixed base 4;

[0024] A limit card block 3, which is fixedly arranged on the front end surface of the lock body bottom plate 1 and is directly opposite to the fixed card seat 4, and a fixed slot 2 is opened on the inner end surface of the limit card block 3;

[0025] The locking device 6 is slidably engaged with the inner end surface of the fixed base 4 through the guide slot 5 .

[0026] The locking device 6 includes a guide slide 62, a fixed plug plate 66 is arranged at the center of the front end surface of the guide slide 62, and an external lock hole 65 is opened on the inner end surface of the fixed plug plate 66, a key insert bracket 67 is arranged on the upper end surface of the fixed plug plate 66 near the rear, a key insert 64 is arranged at the bottom of the key insert bracket 67, a fixed handle 63 is arranged on the upper end surface of the guide slide 62, and an internal operating handle 61 is arranged on the lower end surface of the guide slide 62.

[0027] The fixed plug plate 66 is slidably plugged into the limit block 3 through the fixed slot 2, which can facilitate the fixed plug plate 66 to be quickly and accurately limited to the inside of the limit block 3 to complete the locking operation.

[0028] When the fixed plug plate 66 is inserted to the internal limit of the limit block 3, the external lock hole 65 is completely exposed at the side of the limit block 3. When the fixed plug plate 66 and the limit block 3 are fully inserted and limited, the external lock hole 65 has enough length to facilitate subsequent padlock locking.

[0029] The guide slide 62 is slidably engaged with the inner end surface of the fixed base 4 through the guide slot 5 , which can effectively improve the stability of the subsequent guiding displacement of the guide slide 62 inside the fixed base 4 .

[0030] The side of the key insert 64 does not contact the outer end surface of the lock body bottom plate 1, which can prevent the key insert 64 from being limited by the lock body bottom plate 1 when it is subsequently aligned with the external electronic induction lock.

[0031] Working principle: When in use, if the mechanical padlock is in the closed mode, the user can hold the fixed handle 63, and then limit the fixed handle 63 through the sliding of the guide slide 62 and the guide groove 5, so that the fixed plug plate 66 moves toward the direction of the limit block 3 until the fixed plug plate 66 is fully inserted into the fixed slot 2. At this time, the other side of the fixed plug plate 66 is guided out by the side of the limit block 3. At the same time, the user can lock the padlock to the outside of the fixed plug plate 66 through the external padlock hole 65, thereby completing the locking. If automatic opening and closing is required, at this time The user can position the external induction lock to the front of the lock body bottom plate 1 near the bottom of the limit block 3. The induction lock is a prior art. When the fixed handle 63 drives the fixed plug plate 66 to move sideways, the key insert 64 can be positioned at the sensing point of the induction lock, thereby starting the induction lock and completing the locking of the fixed plug plate 66. At the same time, if the staff is inside the industrial processing fence, the staff can hold the internal operating handle 61 and then pull it to the outside, which can facilitate the separation of the fixed plug plate 66 from the limit block 3, thereby facilitating the staff to open the safety door inside the processing center.
