Problems solved by technology

In the actual use of the above-mentioned door lock structure, it cannot be locked from the inside after the staff enters the gate, which makes it easy for the staff to escape the animals when they are working inside the breeding enclosure
At the same time, if the bolts are installed on both sides of the breeding ground, the staff will need to plug in and out when entering and exiting the door, which will affect the convenience of operation.

Embodiment 1

[0019] like figure 1 and figure 2 The shown door lock for the breeding fence that can realize two-way self-locking processing is arranged on the door panel 1, and the door panel 1 is correspondingly connected to the inside of the door frame 2; the door lock for the breeding fence that can realize two-way self-locking processing includes setting The first fixed end plate 3 on the outer side of the door panel 1 and the second fixed end plate 4 arranged on the inner side of the door panel 1 are provided with rotating handles 5 respectively on the first fixed end plate 3 and the second fixed end plate 4, and the two rotating The handles 5 are connected through the connecting shaft 6; the first fixed end plate 3 is provided with a locking end body 7, which extends parallel to the first fixed end plate 3, and the locking end body 7 is connected to the first fixed end plate 3. The end plates 3 are connected by a locking shaft 8, a locking groove 9 is arranged on the door frame 2, a...

Embodiment 2

[0025] As an improvement of the present invention, the first side 1001 of the adjusting end body 10 includes a first end surface 11 and a second end surface 12 parallel to each other, which respectively extend to the front end surface and the rear of the adjusting end body 10. Above the end surface, when the first edge of the adjusting end body 10 is in a horizontal state, the height of the first end surface 11 is lower than the height of the second end surface 12 . By adopting the above-mentioned technical solution, it is possible to adjust the setting of the first end surface and the second end surface of the end body so that the locking end body can be multi-directionally supported during the working process, thereby making the locking end body in the locked state The support stability is improved.

[0026] The remaining features and advantages of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0028] As an improvement of the present invention, a limiting end body 13 is arranged on the first fixed end plate 3, and the limiting end body 13 and the locking rotating shaft 8 are respectively arranged on both sides of the first fixed end plate 3. The height position of the limiting end body 13 is higher than the height position of the locking rotating shaft 8 . By adopting the above-mentioned technical solution, the rotation angle of the locking end body can be limited in a limited manner through the setting of the limiting end body, thereby effectively preventing the over-rotation of the locking end body from causing damage when it falls.

[0029] The remaining features and advantages of this embodiment are the same as those of Embodiment 2.

Abstract

The invention discloses a door lock capable of achieving bidirectional self-locking treatment and for a breeding fence. The door lock comprises a first fixed end plate and a second fixed end plate which are arranged on the two sides of a door plank and provided with rotary handles. The two rotary handles are connected through a rotary connecting shaft. A locking end body is arranged in the first fixed end plate and connected with the first fixed end plate through a rotary locking shaft. A locking groove is formed in a door frame. The locking end body can extend into the locking groove. An adjusting end body is arranged on one of the rotary handles and comprises a first edge part and a second edge part, and the distance between the first edge part and the locking end body is smaller than that between the second edge part and the locking end body. According to the door lock capable of achieving bidirectional self-locking treatment and for the breeding fence, a worker can open and lock the door both on the inner side and the outer side of the door plank, then the effect that after the worker enters a breeding area, the door lock is in a locked state is effectively guaranteed, and the phenomenon that animals are missed is avoided.

Description

technical field [0001] The invention relates to the field of breeding equipment, in particular to a door lock for breeding fences capable of realizing two-way self-locking processing. Background technique [0002] The door lock in the breeding fence is one of the necessary equipment in the construction process. A reasonable door lock structure can effectively ensure the safety of the breeding place. The door locks of existing breeding fences often adopt traditional bolt-type door locks, that is, bolts are arranged outside the breeding fences for locking the gates. In the actual use of the above-mentioned door lock structure, it cannot be locked from the inside after the staff enters the gate, which makes it easy for the staff to escape the animals during the working process inside the breeding enclosure. Simultaneously, setting bolts on both sides inside and outside the breeding place respectively will cause the staff to perform plugging and unplugging processing in the pro...
