In addition, in order to make the drawings simple and easy to understand, in some drawings, only one of the components with the same structure or function is schematically shown, or only one of them is marked. In this document, "one" not only means "only one", but also means "more than one" situation.

[0047] Referring to Figures 1 to 19 The present embodiment provides a pet residence two-stage frame lock, which comprises a lock seat, a lock piece 3 and a lock pin 4. The lock seat is provided with a movable channel, and the movable channel comprises a first area 1111 and a second area 1113 which are in communication with each other. The lock piece 3 has a lock body part 31 and a limiting part 32, the limiting part 32 extends into the movable channel, when the limiting part 32 is located in the first area 1111, the lock body part 31 locks the movable door 8 in the closed position, and when the limiting part 32 is located in the second area 1113 and in the unlocked posture, the lock body part 31 releases the locking of the movable door 8 in the closed position. The lock pin 4 is movably connected to the lock seat, and when the lock pin 4 is in the locked position, it prevents the limiting part 32 from moving from the first area 1111 to the second area 1113, and the lock pin 4 is configured to leave the locked position under the action of external force.

[0048] When unlocking, first move the lock pin 4 to leave the locked position, then move the limiting part 32 of the lock piece 3 from the first area 1111 to the second area 1113 while keeping the lock pin 4 in the unlocked position, and need to make the limiting part 32 keep in the unlocked posture in the second area 1113, so as to complete the unlocking, and the movable door 8 can be opened.

[0049] The structure of the present embodiment will be described.

[0050] The lock pin 4 and the lock seat are provided with a spring, and the lock pin 4 is kept in the locked position under the elastic force of the spring.

[0051] The movable channel further comprises an intermediate region 1112, the first region 1111 and the second region 1113 are communicated through the intermediate region 1112; the limiting part 32 moves in the movable channel and passes through the intermediate region 1112 to and from the first region 1111 and the second region 1113, that is, the limiting part 32 must pass through the intermediate region 1112 to move from the first region 1111 to the second region 1113. When the locking pin 4 is in the locking position, the locking section 41 of the locking pin 4 is located on the path of the movement of the limiting part 32 in the intermediate region 1112, thereby blocking the movement of the limiting part 32.

[0052] Further, the limiting part 32 extends into the movable channel and the locking area 321 on the limiting part 32 extends out of the movable channel, the area through which the locking area 321 passes when the limiting part 32 moves in the intermediate region 1112 is a transfer region; when the locking pin 4 is in the locking position, the locking section 41 of the locking pin 4 extends into the transfer region to limit the movement of the limiting part 32. In this way, when the limiting part 32 is located in the first region 1111 in the movable channel and the locking pin 4 is in the locking position, the locking area 321 on the limiting part 32 will collide with the locking section 41 of the locking pin 4 in the process of moving to the second region 1113, thereby preventing the limiting part 32 from continuing to move to the second region 1113.

[0053] Next, the specific structure of the pet house two-stage frame lock of the embodiment will be further described with a specific pet house as an example, which can be specifically referred to Figures 1 to 19 .

[0054] The pet house comprises a movable door 8 and a fixed door 9 (only the movable door 8 and the fixed door 9 in the pet house are schematically shown in the figure, but this does not mean that the pet house only has the movable door 8 and the fixed door 9), the fixed door 9 is fixed with the main body part of the pet house, and the movable door 8 can be rotated to open relative to the main body part of the pet house. The movable door 8 can be opened by rotating the movable door 8, so that the pet can enter or leave the pet house through the channel exposed after the movable door 8 is opened. The pet house two-stage frame lock of the embodiment is installed on the fixed door 9 and can lock the movable door 8 in the closed position (the movable door 8 is in the closed position) Figure 9 . Of course, in other embodiments, the pet house can have other shapes, which are not limited here; the installation position of the pet house two-stage frame lock of the embodiment can be adjusted according to actual conditions.

[0055] The lock seat comprises a main lock seat 1 and a secondary lock seat 2, the main lock seat 1 is mainly used for setting a movable channel and mounting the lock seat on the fixed door 9 of the pet house, and the secondary lock seat 2 is fixedly connected to the main lock seat 1, and the secondary lock seat 2 is mainly used for mounting the locking pin 4.

[0056] Specifically, the main lock seat 1 may include two parallel and spaced main lock seat plates 11, which are connected by a first connecting plate 12 to form a whole; preferably, the two main lock seat plates 11 and the first connecting plate 12 may be integrally made.

[0057] The main lock seat 1 is fixedly installed on the square post 91 of the fixed door 9 by a fixing component 5, which includes a U-shaped clamp 51, a baffle 52, and two wing nuts 53. The two main lock seat plates 11 and the first connecting plate 12 form a U-shaped structure, which is fastened to the square post 91 of the fixed door 9. The U-shaped clamp 51 is fitted over the U-shaped structure of the main lock seat 1, and the U-shaped clamp 51 and the U-shaped structure of the main lock seat 1 face the same direction. The baffle 52 is set at the opening of the U-shaped structure of the main lock seat 1, forming an accommodating space 14 with the U-shaped structure of the main lock seat 1, and the square post 91 is located in the accommodating space 14. The two arms 512 of the U-shaped clamp 51 pass through the two through holes on the baffle 52 and are threadedly fastened to the two wing nuts 53. After the wing nuts 53 are tightened, they can press the square post 91 between the first connecting plate 12 and the baffle 52, thereby fixing the main lock seat 1 on the square post 91.

[0058] Furthermore, the main lock seat 1 has a first side and a second side, with a baffle 52 disposed on the first side of the main lock seat 1. The portion of the main lock seat 1 facing its second side is provided with a groove 13. The middle portion 511 of the U-shaped clamp 51 is inserted into the groove 13, thereby allowing the position of the U-shaped groove to be fixed on the main lock seat 1 and preventing the main lock seat 1 from detaching from the U-shaped clamp 51 and the square post 91 in the direction along the first straight line (the two main lock seat plates 11 and the first connecting plate 12 of the main lock seat 1 form a U-shape in a plane perpendicular to the first straight line), thus increasing the stability of the main lock seat 1 fixedly installed on the square post 91.

[0059] The depth direction of the groove 13 is specifically the thickness direction of the first connecting plate 12. The length of the two main lock seat plates 11 in the first straight direction is greater than the length of the first connecting plate 12. Thus, along the first straight direction, the upper part of the main lock seat 1 consists of two parallel and spaced-apart main lock seat plates 11, and the lower part of the main lock seat 1 consists of a U-shaped structure formed by the two main lock seat plates 11 and the first connecting plate 12. When the groove 13 is provided in the upper part of the main lock seat 1, the groove 13 is provided on each of the two main lock seat plates 11 (e.g., Figure 5 (As shown); when the groove 13 is set at the lower part of the main lock seat 1, the groove 13 is set on the first connecting plate 12. If the depth of the groove 13 is greater than the thickness of the first connecting plate 12, the groove 13 will extend to the two main lock seat plates 11.

[0060] Of course, in other embodiments, the main lock seat 1 can also be installed on the fixed door 9 in other ways, such as by welding.

[0061] The active channel is arranged on the upper part of the main lock seat 1. Specifically, through holes 111 are arranged on the two main lock seat plates 11 respectively, and the limiting portions 32 pass through the through holes 111 on the two main lock seat plates 11 respectively. The cross section (here, the cross section refers to the cross section formed on the plane perpendicular to the thickness direction of the main lock seat plate 11) of the portion of the limiting portion 32 in the through hole 111 is non-circular, the size of the first region 1111 limits the rotation of the limiting portion 32 in the first region 1111 within a preset angle range, and the size of the second region 1113 is configured to allow the limiting portion 32 to rotate to an angle exceeding the preset angle range to rotate to the unlocking posture.

[0062] Specifically, the cross section (here, the cross section refers to the cross section formed on the plane perpendicular to the thickness direction of the main lock seat plate 11) of the through hole 111 can be a combination of a circle and a square, and one end of the length direction of the square communicates with the circle. Among them, the circle corresponds to the second region 1113; one end of the length direction of the square which does not communicate with the circle corresponds to the first region 1111, and the remaining part corresponds to the intermediate region 1112.

[0063] The auxiliary lock seat 2 includes two installation plates 21 arranged side by side and spaced apart, and the two installation plates 21 can be connected by a second connecting plate 22 to form a whole; preferably, the two installation plates 21 and the second connecting plate 22 can be integrally manufactured. The auxiliary lock seat 2 is installed on one of the main lock seat plates 11 and located on the surface of the main lock seat plate 11 away from the other main lock seat plate 11; specifically, the second connecting plate 22 can be attached to the surface of the main lock seat plate 11, and the second connecting plate 22 can be fixed on the corresponding main lock seat plate 11 by adhesive connection, welding connection, fastener connection, etc.

[0064] The lock pin 4 has a locking section 41 at one end and a limiting portion 42 at the other end. The end of the lock pin 4 with the locking section 41 sequentially passes through the installation holes on the two installation plates 21 and protrudes, and the lock pin 4 is in sliding connection with the installation holes on the two installation plates 21. The elastic member is used to drive the lock pin 4 to slide towards the end with the locking section 41, and the limiting portion 42 is used to prevent the lock pin 4 from being pulled out of the installation hole under the action of the elastic member.

[0065] Specifically, the elastic member can be a spring 6, which is sleeved on the locking pin 4 and located between the two mounting plates 21; the locking pin 4 is provided with an abutting portion on the portion between the two mounting plates 21, and the two ends of the spring 6 abut against the abutting portion and the mounting plate 21 relatively close to the limiting portion 42 among the two mounting plates 21 respectively. The abutting portion can be a shaft pin 7, which is inserted and fixed on the locking pin 4, and the two ends of the shaft pin 7 protrude for abutting against the spring 6. One end of the locking pin 4 without the locking section 41 is bent in the radial direction after penetrating the two mounting plates 21 to form the limiting portion 42.

[0066] The limiting portion 32 in the lock piece 3 can be a plate similar to a rectangle, and the two ends thereof penetrate the through holes 111 in the two main lock seat plates 11 respectively, and the side wall of the portion between the two main lock seat plates 11 is connected with the lock body portion 31.

[0067] The lock body portion 31 is provided with a lock groove 311. When the limiting portion 32 is located in the first region 1111, the lock groove 311 extends into the region where the movable door 8 is located, and the two opposite inner side walls 3111 of the lock groove 311 are located on the two sides of the movable door 8 in the closed position to limit the rotation of the movable door 8. When the limiting portion 32 is located in the second region 1113 and in the unlocked posture, the lock groove 311 is away from the region where the movable door 8 is located.
