Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please refer to Figures 1 to 6This utility model provides a lock, including a fixed base 1, a locking plate 2, and a locking rod 3; the locking plate 2 is vertically slidably disposed in the fixed base 1; the locking plate 2 is provided with a hook groove 311 that cooperates with the locking rod 3; when the locking rod 3 passes through the locking plate 2, the locking rod 3 lifts the locking plate 2; after the locking rod 3 enters the hook groove 311, the locking plate 2 falls down naturally.

[0025] In this embodiment of the invention, the latch includes a fixing base 1, a locking plate 2, and a locking rod 3. The fixing base 1 is installed on the cage body of the pet cage, and the locking rod 3 is installed on the door 4 of the pet cage, which is rotatable and can be opened and closed. With the locking rod 3 and the locking plate 2 in place, when the door 4 is closed, the locking rod 3 moves with the door 4 and passes through the locking plate 2, contacting the locking plate 2. The locking rod 3 lifts the locking plate 2 and then enters the hook groove 311. The hook groove 311 has a certain space, so the locking plate 2 falls down under its own weight and locks the locking rod 3, so that the door 4 and the cage body are locked.

[0026] Specifically, a ramp can be provided on the locking plate 2. When the locking rod 3 contacts the locking plate 2, the locking rod 3 presses against the ramp, causing the locking plate 2, which can freely slide up and down on the fixed base 1, to move vertically upward, thereby lifting the locking plate 2. The locking mechanism works as follows:

[0027] Closing phase: As the cage door closes, the locking rod 3 moves toward the fixed seat 1. When the rod of the locking rod 3 contacts the locking plate 2, it pushes the locking plate 2 vertically upward.

[0028] Locking phase: Locking bar 3 continues to move and passes over locking plate 2, entering the hook groove 311 of locking plate 2. At this time, locking plate 2 loses the support of locking bar 3 and falls naturally by its own gravity. Hook groove 311 locks locking bar 3, completing the locking.

[0029] Unlocking phase: Manually pull the locking plate 2 upwards to disengage the hook groove 311 from the locking rod 3, allowing the locking rod 3 to move freely and open the cage door.

[0030] With the above-described structure, the latch of this utility model has the following advantages: First, it enables quick locking and is easy to operate. When closing the door, the locking rod 3 pushes the locking plate 2 upward, and after entering the hook groove 311, the locking plate 2 automatically falls and locks itself. There is no need for manual twisting or hooking; locking can be completed with one hand, making operation more efficient when holding a pet. Furthermore, it prevents pets from accidentally opening the latch, ensuring high safety. The locking plate 2 only moves upward when pushed by the locking rod 3 in the closing direction. When a pet pushes the door from the inside, the locking plate 2 cannot unlock due to gravity and the hook groove 311 structure, eliminating the risk of "push-opening the door." The structure is concealed with no exposed parts, reducing the possibility of pets biting and triggering unlocking. In addition, the mechanical structure is reliable and durable. Locking is achieved by gravity, the structure is simple, and it is not prone to failure after long-term use, resulting in low maintenance costs. Finally, it is highly flexible. The fixing base 1 can be installed on cages made of different materials such as metal and plastic. The depth of the hook groove 311 can be customized according to the size of the locking rod 3, ensuring a firm lock and moderate unlocking force.

[0031] Preferably, the fixed base 1 includes an upper sliding base 11 and a lower sliding base 12. The upper sliding base 11 has the same structure as the lower sliding base 12, and the two are symmetrically arranged. One end of the locking plate 2 is provided with a first locking part 31, and the other end is provided with a second locking part 32. The structure of the first locking part 31 is the same as the structure of the second locking part 32. The first locking part 31 is configured to cooperate with the upper sliding base 11, and the second locking part 32 is configured to cooperate with the lower sliding base 12. The first locking part 31 and the second locking part 32 are respectively provided with hook grooves 311. There are two locking rods 3, and the two locking rods 3 are respectively configured to cooperate with the hook grooves 311 on the first locking part 31 and the second locking part 32.

[0032] In this embodiment, through the symmetrical arrangement of the upper sliding block 11 and the lower sliding block 12, the first and second locking parts 32 at both ends of the locking plate 2 cooperate with the upper and lower sliding blocks 12 respectively, and the two locking rods 3 lock synchronously, forming a bidirectional constraint, preventing the cage door from loosening due to force in one direction, and improving the overall impact resistance of the structure. The double locking rod 3 design increases the difficulty of unlocking, as the pet needs to break the locking state of both upper and lower locking rods 3 simultaneously to open the door. However, the symmetrical structure makes the locking plate 2 evenly stressed, so even if it is pushed in one direction, the locking rod 3 in the other direction can still remain locked, effectively preventing the door leaf 4 from being damaged. When closing the door, the double locking rods 3 push the upper and lower ends of the locking plate 2 synchronously, and the locking plate 2 slides vertically along the symmetrical sliding blocks, making the locking process smoother. When unlocking, simply pull the locking plate 2 to release the double locking rods 3 simultaneously, which can still be completed with one hand, without adding any extra steps due to the double locking structure. Furthermore, the symmetrical structure is compatible with cage doors of different sizes (such as tall doors), preventing tilting caused by uneven force on the single locking bar 3; the symmetrical fit between the slide and the locking part can reduce structural damage when pets bite at a single point, extending service life. The upper and lower slides 12 can be independently disassembled and installed, adapting to cages made of different materials such as metal and wood; if a single component of the double locking bar 3 structure is damaged, it can be replaced individually, resulting in low maintenance costs.

[0033] Preferably, the upper slide 11 includes an outer side plate 111 and an inner side plate 112, the outer side plate 111 and the inner side plate 112 are connected by a pair of arched pieces 113; a limiting shaft 114 is provided between the inner side plate 112 and the outer side plate 111, the locking plate 2 is provided with a limiting groove 312, and the limiting shaft 114 passes through the limiting groove 312; the outer side plate 111 and the inner side plate 112 are respectively provided with locking grooves 115, and guide slopes 116 are respectively provided on both sides of the opening of the locking groove 115.

[0034] In this embodiment, the limiting shaft 114 passes through the limiting groove 312 of the locking plate 2, restricting the locking plate 2 to slide only in the vertical direction and preventing it from falling off. This ensures that the locking plate 2 is precisely aligned with the locking rod 3 when moving up and down, improving locking reliability. The guide ramps 116 on both sides of the opening of the locking groove 115 can automatically guide the locking rod 3 into the groove when it approaches. When closing the door, the locking rod 3 pushes the locking plate 2 upward along the ramps, reducing frictional resistance. Even with a light push of the cage door with one hand, locking can be completed, improving the smoothness of operation and reducing the risk of incomplete locking due to jamming.

[0035] Preferably, the outer side plate 111 is provided with an outer mounting hole 111a; the inner side plate is provided with a side connecting plate 117, and the side connecting plate 117 is provided with an inner mounting hole 117a. In this embodiment, the outer mounting hole 111a of the outer side plate 111 can be directly fixed to the outer frame of the cage door, and the inner mounting hole 117a on the side connecting plate 117 of the inner side plate 112 can be connected to the surface of the cage door, realizing two-way fixing and adapting to door panels of different thicknesses or irregularly shaped mounting surfaces. By fixing the installation from both sides, the entire latch structure forms a rigid connection with the cage door, which has strong stability and better tensile strength, and can effectively avoid the problem of the latch loosening or falling off when the pet hits it, which is especially suitable for large pet cages. The outer mounting hole 111a can be used with expansion screws, self-tapping screws, etc. to fix to the wooden / plastic cage body, and the inner mounting hole 117a is connected to the metal cage body by bolts. The dual mounting position design takes into account the installation needs of different materials and reduces the cost of adaptation and modification.

[0036] Preferably, the first locking part 31 includes a first guide slope 313 and a second guide slope 314; the hook groove 311 includes an inner sidewall 311a and an outer sidewall 311b, the first guide slope 313 is disposed on the outer sidewall 311b of the hook groove 311, and the second guide slope 314 is connected to the inner sidewall 311a of the hook groove 311. In this embodiment, the first guide slope 313 is disposed on the outer sidewall 311b of the hook groove 311. When the locking rod 3 approaches, the first guide slope 313 can guide the locking rod 3 to quickly align with the entrance of the hook groove 311, so that the entire locking plate 2 can rise smoothly, reducing the difficulty of alignment when closing the door, and achieving the effect of "locking with a touch", which is especially suitable for scenarios where the cage needs to be closed quickly in a panic (such as when a pet escapes). The second guide slope 314 connects to the inner wall 311a of the hook groove 311. After the locking rod 3 enters the hook groove 311, the second guide slope 314 and the inner wall 311a form a gradient groove structure. When unlocking is required, the locking plate 2 is manually pulled up, and the entire locking plate 2 rises. The locking rod 3 gradually contacts the second guide slope 314 along the inner wall 311a of the hook groove 311. At this time, the locking rod 3 is squeezed out of the hook groove 311 by the second guide slope 314, so that the locking rod 3 gradually leaves the area of ​​the hook groove 311 until it is completely separated from the hook groove 311, thus achieving unlocking.

[0037] With the above structural setup, the first guide slope 313 guides the locking rod 3 into the hook groove 311, and the second guide slope 314 guides the locking rod 3 out of the hook groove 311. The cooperation of the two guide slopes makes the locking and unlocking process smoother and the operation of the latch more convenient.

[0038] Preferably, the locking plate 2 has an arc-shaped groove 33 in the middle. In this embodiment, the arc-shaped groove 33 allows people to intuitively see the position of the locking plate 2. By manually grasping the arc-shaped groove 33 and lifting the locking plate 2 upward, the locking plate can be unlocked.

[0039] Preferably, the bottom of the lock plate 2 is provided with a limiting hole 34, and a detachable pin is provided on the limiting hole 34. In this embodiment, the pin and the latch are combined, and when inserted, the lock plate 2 can be fixed to prevent pets from pushing open the lock bar 3, forming a double anti-escape protection. The pin is detachable, making it convenient to open the door in daily life, and its insertion enhances security, adapting to different usage scenarios. The limiting hole 34 is located at the bottom of the lock plate 2, in a concealed position, to prevent pets from accidentally touching or hooking it, reducing accidental unlocking.

[0040] Preferably, the fixing base 1 is made of stainless steel, and the locking plate 2 is made of plastic.

[0041] Preferably, the device further includes a spring disposed inside the fixed base 1, one end of which is connected to the fixed base 1 and the other end to the locking plate 2. The spring is used to push the locking plate 2 downward from the fixed base 1. In this embodiment, the spring pushes the locking plate 2 down quickly to lock the locking rod 3, locking the door upon closing without manual operation. The spring force prevents the locking plate 2 from failing to fall automatically due to jamming, making the locking structure more reliable.

[0042] Compared with existing technologies, the advantages of this invention are as follows: When the door is pushed to close, the locking rod lifts the locking plate, which then falls and automatically locks itself after entering the hook groove. No additional operation is required; locking is completed with one hand, making operation simple. The locking plate and locking rod are locked vertically, preventing the pet from triggering unlocking when pushing the door outward, thus reducing the risk of escape. The mechanical structure of this invention is stable, relying on gravity for locking, with no easily damaged parts, and is not prone to loosening even after long-term use. To unlock, simply lift the locking plate to quickly open the door, without the need for a key or complicated steps, making it suitable for quickly opening and closing the cage door with one hand when holding a pet. Furthermore, the locking structure of this invention is simple, highly flexible, and widely applicable, adaptable to cages of various materials.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
