Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Appendix Figure 1-8 As shown, a pet cage spring flat door lock includes a lock shell and a lock cylinder. The lock shell includes a lower shell 1 and an upper shell 5. The lower shell 1 is rectangular and has a latch 1-7 at one end. An extension plate is integrally provided on the lower side of the latch 1-7. A protruding stop 1-1 is provided at the end of the extension plate. A movable plate hole 1-6 is provided on the lower side of the stop 1-1. A guide groove 1-5 is provided in the lower shell 1 and communicates with the movable plate hole 1-6. Two horizontal holes 1-3 are provided on one side of the lower shell 1 corresponding to the movable plate hole 1-6. A through vertical hole 1-2 is provided on both sides. The two horizontal holes 1-3 and the vertical hole 1-2 form a π-shaped channel. A latch 1-4 is provided on each side of the lower shell 1. Two slots 5-1 are provided at corresponding positions on the upper shell 5. The lower shell 1 and the upper shell 5 are connected together by the latch 1-4 and the slots 5-1. The lock cylinder includes a bolt 2, a movable plate 3, and a guide plate 4. The bolt 2 is mounted on the upper side of the movable plate 3, and the movable plate 3 is slidably mounted on the guide plate 4. The lock cylinder is mounted inside the lock housing. The movable plate 3 protrudes from the movable plate holes 1-6, and the bolt 2 can pop out from the bolt opening 1-7 or retract into the lock housing.

[0025] The locking tongue 1-7 on the lower housing 1 is kept at a distance greater than the diameter of a pet cage rod from the extension plate of the lower housing 1.

[0026] The movable plate 3 is a long strip. It has a manual handle 3-1 that protrudes downwards from the outer end of the lock shell and a rectangular slot 3-2 inside the lock shell. A locking block 2-1 is located on the lower side of the middle of the lock tongue 2. The locking block 2-1 is inserted into the slot 3-2 to fix the two together.

[0027] A one-way blind tube 2-2 is provided at the rear end of the locking tongue 2. A spring 6 is provided inside the one-way blind tube 2-2. The outer end of the spring 6 presses against the rear wall of the lower housing 1 to keep the locking tongue 2 in the extended state. The latch 2 has an arc-shaped bevel extending outwards towards the bottom surface of the lower housing 1, which makes it easy to retract into the housing when it encounters pressure from the pet doorpost.

[0028] The guide plate 4 is U-shaped, with a rectangular spring limiting hole 4-1 in the middle of the bottom surface. Two guide plate latches 4-2 are provided on the outer sides of each of the two side walls. Four corresponding upright plates are provided on the bottom surface of the lower housing 1. Guide plate slots 1-8 are provided on the upright plates. The guide plate latches 4-2 are engaged in the guide plate slots 1-8 to fix the guide plate 4 to the lower housing 1.

[0029] Half of the one-way blind tube 2-2 is located inside the rectangular spring limiting hole 4-1 of the guide plate 4. The spring limiting hole 4-1 is used to limit the movement distance of the one-way blind tube, thereby limiting the length of the locking tongue 2 protruding from the lower housing 1.

[0030] Appendix Figure 9 , 10 As shown, the pet cage door has two horizontal door bars 7 and one vertical door bar 8 installed in the π-shaped channel on the shell. The latch 2 and the door frame bar 9 are in the same position. When you need to open the pet cage door, press the manual handle 3-1 to move the latch 2 back into the shell, and the pet door can be opened. When closing, due to the weight of the pet door, the curved slope of the latch will automatically retract into the shell when it touches the door frame bar 9, and then reset to lock the door frame bar 9 under the latch, thus closing the door.

[0031] The beneficial effects of this utility model are: the pet cage door can be opened and closed with one hand, which is very convenient.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
