[0021] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0022] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figures 1 to 7 This utility model provides a pet door lock device, including a rear door component 2, a movable door 3, and a knob operation assembly 4. The upper end of the movable door 3 is pivotally connected to the rear door component 2, and the lower end of the movable door 3 is connected to the rear door component 2 through the knob operation assembly 4. The knob operation assembly 4 includes a knob 41, a knob front stop 42 connected to the inner side of the knob 41, a rear stop component 45 connected to the inner side of the knob front stop 42, and a knob rear stop 46 disposed on one side of the rear stop component 45. The movable end of the movable door 3 is provided with a movable door passage notch 31 at the position corresponding to the knob operation assembly 4, and the knob rear stop 46 is located on the inner side of the movable door 3.

[0026] The aforementioned pet door lock device, by rotating the front stop 42 and the rear stop 46 of the knob respectively, restricts the front and rear ends of the movable door 3, thereby realizing four states of the movable door: only entry, locked, only exit, and free mode, which is convenient to use.

[0027] Specifically, in this embodiment of the invention, the front stop 42 of the knob and the knob 41 are an integral unit, and the rear stop 46 of the knob is locked to the knob operating assembly 4 by screws. Therefore, when the knob 41 is rotated, the two stops move together. During installation, the front stop 42 and the rear stop 46 of the knob are designed to be spaced apart and located in the same semicircular area. When the knob 41 is rotated, different restrictions on the movable door 3 can be achieved (see [link to relevant documentation]). Figures 4-7 )

[0028] In one embodiment of this utility model, a reset component is further included. The reset component comprises two magnetic metal blocks 5 and two magnets 6. The magnetic metal blocks 5 are disposed at the end of the movable door 3, and the magnets 6 are disposed on the rear door component 2 and are arranged in a one-to-one correspondence with the magnetic metal blocks 5. The corresponding magnetic metal blocks 5 and magnets 6 attract each other. When the movable door 3 moves in and out, the magnets 6 magnetically attract the magnetic metal blocks 6, thereby achieving the reset effect of the movable door 3. Specifically, the magnetic metal blocks 5 can be made of magnetic materials such as iron, cobalt, nickel, and rubidium, or their alloys.

[0029] In one embodiment of this utility model, the rear stop block component 45 is provided with two limiting protrusions 44 at intervals near one end of the knob front stop block 45. Each limiting protrusion 44 is provided with a limiting spring 43. The rear door component 2 is provided with a limiting groove 21 at the position corresponding to the limiting protrusions 44. When the limiting protrusion 44 reaches the limiting groove 21, the force of the limiting spring 43 will push the limiting protrusion 44 into the limiting groove 21, forming a certain resistance. At this time, the knob front stop block 42 is exactly in a functional position (only in, no out, locked, only out, and free mode), realizing the limiting function. When rotated again, the protrusion 44 can leave the limiting groove 21 because the limiting spring 43 can be compressed.

[0030] In one embodiment of this utility model, the movable door 3 is provided with multiple ventilation holes so that the pet can breathe or observe the external environment.

[0031] In one embodiment of this utility model, the surface of the knob 41 is provided with an anti-slip structure to improve the ease of operation.

[0032] In one embodiment of this utility model, the anti-slip structure can be either anti-slip protrusions or anti-slip grooves to achieve the anti-slip function.

[0033] In one embodiment of the present invention, a front door component 1 is also provided at the front end of the rear door component 2. The front door component 1 is snap-fitted to the rear door component 2. The front door component 1 can serve to fix the knob operation component 4 and for decoration.

[0034] The aforementioned pet door lock device fixes the knob operation assembly 4 to the rear door component 2, and secures the movable door 3 to the rear door component 2 via the front door component 1 (see [link]). Figure 2 The mode is switched by rotating knob 41. When knob 41 is rotated until the front stop 42 is to the right of the passage opening 31 of the movable door, it is an in-only mode. In this mode, the pet can enter through the movable door 3. When exiting, the movable door 3 will be blocked by the front stop 42 of the knob because the passage opening 31 of the movable door is blocked (see [link]). Figure 4When the knob 41 is rotated until the front stop 42 is to the left of the access opening 31 and the rear stop 46 is to the right of the access opening 31, it is in locked mode. In this mode, the pet's entry and exit are restricted by the front stop 42 and the rear stop 46 of the knob (see [link]). Figure 5 When knob 41 is turned and the stop 46 is to the left of the passage opening 31 of the movable door, it is in an exit-only mode. In this mode, the pet will be unable to enter because the stop 46 is restricted from entering the passage opening 31 of the movable door (see [link]). Figure 6 When knob 41, the front stop 42, and the rear stop 46 are all below the movable door 31, it is in free entry and exit mode. In this mode, pets can freely enter and exit through the movable door 3 (see [link]). Figure 7 When the knob 41 is rotated, the limiting protrusion 44 is limited by the limiting groove 21, and the limiting spring 43 can achieve a rebound operation when the knob 41 is rotated, which improves the operating feel while limiting the movement (see [link]). Figure 3 When the movable door 3 moves in and out, the magnet 6 magnetically attracts the magnetic metal 5, causing the movable door 3 to reset (see [link]). Figure 1 ).

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
