Description

Technical Field

[0001] This utility model relates to the technical field of animal husbandry, specifically to a novel door lock. Background Technology

[0002] Nowadays, cattle farming is becoming increasingly large-scale. In the process of cattle farming, it is necessary to carry out operations such as artificial insemination, information collection, and disease treatment. However, due to the large size of cattle, the above operations are dangerous to the workers if they are not restrained. Usually, cattle restraint frames are needed to restrict the movement range of cattle and fix them in a limited manner, limiting the cattle's mobility and aggression ability, so as to facilitate the effective operation of cattle by workers and ensure the safety of workers and cattle. Therefore, cattle restraint frames are one of the indispensable production tools for cattle farmers.

[0003] A cattle restraint frame typically consists of a frame, safety securing devices, adjustment devices, a work platform, and a door lock. Existing cattle restraint frames usually use traditional door locks for locking. However, traditional door locks are cumbersome to operate during locking and unlocking, and cannot be completed in a very short time. Since cattle frequently and continuously enter and exit the cattle restraint frame, the action of opening and closing the door lock is repeated many times in a short period of time, which not only causes inconvenience to the operation, but also prolongs the time for cattle to enter and exit the cattle restraint frame, reducing work efficiency. In addition, the door lock key is not easy to keep safe. If it is lost, it will cause inconvenience and trouble to the operation, affecting the normal and smooth progress of the operation.

[0004] Therefore, based on the above problems, the present invention provides a novel door lock. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] To address the technical problems in the background section, a novel door lock is proposed as follows:

[0028] Combination Figure 1-4 As shown, the present invention provides a novel door lock, including a mounting plate 1, a fixing plate 5 on one side of the mounting plate 1, the fixing plate 5 being connected to the door panel, and a cooperating lock 4 being installed on one side of the fixing plate 5, the cooperating lock 4 cooperating with the mounting plate 1.

[0029] The mounting plate 1 is evenly provided with a number of mounting bolts 2 and is connected to the cattle shed frame through the number of mounting bolts 2. The fixing plate 5 is evenly provided with a number of fixing bolts 6 and is connected to the door panel through the number of fixing bolts 6.

[0030] By installing the connecting plate 1 and several mounting bolts 2, the connecting plate 1 can be easily detachably installed on the cattle restraint frame. At the same time, by fixing the connecting plate 5 and the door panel with several fixing bolts 6, the fixing connecting plate 5 can be easily detachably installed on the door panel (the door panel is movably hinged to the cattle restraint frame through several hinges). This not only facilitates the later installation and replacement, but also simplifies the operation and helps to increase the service life of the overall device.

[0031] The locking component 4 includes several L-shaped connecting plates 41. Each L-shaped connecting plate 41 is fixedly connected to the fixed connecting plate 5. An elliptical through groove 411 is provided on the opposite surface of two adjacent L-shaped connecting plates 41. A T-shaped limiting rod 44 is slidably provided between two adjacent elliptical through grooves 411. A matching component is provided between two T-shaped limiting rods 44. A matching component is provided between each T-shaped limiting rod 44 and the corresponding L-shaped connecting plate 41.

[0032] One end of each T-shaped limiting rod 44 extends to the outside of the corresponding L-shaped connecting plate 41 and is equipped with a limiting sleeve 42. Two L-shaped mating locking grooves 3 are symmetrically opened on one side of the mounting connecting plate 1, and each limiting sleeve 42 is located in the corresponding L-shaped mating locking groove 3.

[0033] The mating components include two limiting blocks 441, each of which is fixedly connected to a corresponding T-shaped limiting rod 44. A mating spring 47 is provided between the two limiting blocks 441 and the two blocks are fixedly connected by the mating spring 47. A positioning element is provided inside the mating spring 47 and is installed between the two limiting blocks 441. The positioning element includes a positioning rod 46, which is fixedly connected to the upper limiting block 441. A positioning cylinder 48 is slidably sleeved on the positioning rod 46. A connecting column is fixedly provided at the bottom end of the positioning cylinder 48 and is fixedly connected to the lower limiting block 441. An extension rod 49 is fixedly provided on the opposite surface of each of the two T-shaped limiting rods 44, and a handle 43 is fixedly provided on the opposite end of each of the two extension rods 49.

[0034] For specific usage, please refer to Figure 1 When the door lock needs to be opened in one direction, by holding the two handles 43, the two handles 43 are moved relative to each other, which in turn causes each T-shaped limit rod 44 to slide along the corresponding elliptical through groove 411, thereby causing the positioning rod 46 to slide along the positioning cylinder 48, causing the cooperating spring 47 to retract. In this way, each limit sleeve 42 is simultaneously moved along the corresponding L-shaped cooperating lock groove 3. When it slides to a certain position, by pulling the handle 43 outward, and simultaneously engaging the hinge, each limit sleeve 42 is disengaged from the corresponding L-shaped groove. With the lock groove 3, the door panel can be opened (to unlock). When locking the door, by moving the door panel and holding the handle 43, the limiting sleeves 42 move relative to each other. Then, by moving the door panel, each limiting sleeve 42 enters the corresponding L-shaped locking groove 3. When the limiting sleeve 42 enters the L-shaped locking groove 3, the handle 43 is released. At the same time, under the cooperation of the extension force of the spring 47 and the positioning rod 46 and positioning cylinder 48, the two limiting sleeves 42 move in opposite directions and are limited to the corresponding L-shaped locking groove 3. In this way, the locking function is achieved.

[0035] In summary, by coordinating the lock component 4, the mounting plate 1, the fixing plate 5, and other components, the problem of cumbersome operation in locking and unlocking doors using traditional techniques is effectively solved. Moreover, the overall structure is ingeniously designed, enabling keyless opening, and is highly practical and easy to promote.

[0036] Example 2

[0037] like Figure 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0038] The mating component includes a limiting slide groove 412, which is opened through the L-shaped connecting plate 41. A limiting slider 45 is slidably provided in the limiting slide groove 412. A circular mounting hole is opened through the limiting slider 45. A T-shaped limiting rod 44 is fixedly installed in the circular mounting hole.

[0039] In practical use, based on Embodiment 1, if it is necessary to further enhance the practicality of the overall device, the operation is as follows:

[0040] When the door lock is opened or closed, the two T-shaped limit rods 44 move relative to each other and in opposite directions, which simultaneously drives each limit slider 45 to slide along the corresponding limit groove 412. This not only effectively increases the stability of the door lock when it is opened or closed, but also further increases the practicality of the overall device.
