Description

Technical Field

[0001] This utility model relates to the field of sealed door lock technology, specifically to a sealed door lock structure for a pet spa machine that is easy to open and close. Background Technology

[0002] Pet spas are widely used as an important form of rehabilitation and fitness to help pets recover from surgery, relieve arthritis pain, lose weight, and engage in daily exercise. A pet spa machine is the key equipment for achieving this function; it typically includes a tank that can accommodate the pet and is filled with and maintained at a certain level of warm water. For easy access for the pet, the spa machine tank must have an openable door.

[0003] In the design and use of pet spa machines, the sealing performance and locking reliability of the door are crucial technical aspects. On one hand, the door must form a reliable waterproof barrier to withstand the static pressure of the water inside the enclosure, preventing leaks and seepage during the spa process. Leaks not only waste water and make the floor slippery, but more seriously, they can soak electrical components at the bottom of the equipment (such as heaters, water pumps, and control circuits), causing equipment malfunctions or even electrical accidents. On the other hand, the door lock structure must be robust enough to withstand the pet's movement, bumps, or scratches inside the enclosure, preventing the door from being accidentally pushed open and ensuring the pet's safety.

[0004] Currently, the door locking mechanisms of some pet spa machines or similar water containers on the market mainly adopt the following methods: A simple latch or snap-on structure is the most common method. One or more mechanical latches secure the door panel to the door frame. First, the tightening force applied is uneven and usually weak, making it difficult to generate continuous, even pressure across the entire door frame seal. Especially when the water level and pressure inside the tank are high, the door panel is prone to slight deformation, leading to gaps in the seal and leakage. Second, these latches have limited mechanical strength and are prone to wear and loosening after prolonged and repeated use, further reducing the tightening force and resulting in poor reliability.

[0005] Bolted fastening structures, seen on some industrial-grade water tanks, involve tightening multiple bolts or handwheels around the door. While this method provides strong, even locking force and a good seal, it is extremely cumbersome and time-consuming. Each time the door is opened or closed, multiple bolts need to be tightened or loosened individually, making it completely unsuitable for pet spa equipment that requires frequent opening and closing, resulting in a very poor user experience.

[0006] In summary, existing pet spa machine door lock structures generally suffer from one or more problems such as insufficient sealing pressure, uneven locking force, poor long-term reliability, inconvenient operation, or insufficient security, making it difficult to simultaneously meet the multiple requirements of efficient sealing, robust locking, convenient operation, and safe and reliable operation. Utility Model Content

[0007] This invention provides a sealed door lock structure for a pet spa machine that is easy to open and close, aiming to solve the problems mentioned in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A sealing door lock structure for a pet spa machine that is easy to open and close includes a spa machine housing, the spa machine housing including a housing frame and a hinged door on the housing frame, and further includes: A lock body is fixedly installed on the frame of the spa machine housing. The frame has a mounting cavity for installing the lock body, and a rotating and pressing assembly is installed in the mounting cavity. The rotary pressing assembly includes a fixed plate installed inside the mounting cavity, a rotating shaft rotatably inserted into the fixed plate, two sets of pressing actuators installed in the middle of the rotating shaft, each pressing actuator including an eccentric wheel mounted on the rotating shaft, a flange above each of the two sets of eccentric wheels, an opening groove at the farthest end of the flange near the shaft core, a positioning seat for positioning the rotating shaft at the bottom of the mounting cavity, the rotating shaft being inserted into the positioning seat, and a return spring sleeved on the bottom of the rotating shaft, a limit plate also provided on the outside of the rotating shaft, one end of the return spring abutting against the positioning seat, and the other end abutting against the limit plate; The lock is fixed to the door and works in conjunction with the pressing actuator to lock and seal the door.

[0009] Preferably, the lock includes an extension plate fixed to the outer side of the door, a locking rod connected to one side of the extension plate, and a groove formed below the outer end of the locking rod.

[0010] Preferably, the housing frame is provided with a clearance groove, the position of which matches the position of the locking rod. When the door is opened or closed, the locking rod is inserted into the clearance groove and cooperates with the pressing actuator to lock the door.

[0011] Preferably, a rotating handle is connected to the top of the rotating shaft, a fixed disc is provided on the rotating handle, a positioning sleeve is provided on the fixed disc, a positioning pin is slidably inserted into the positioning sleeve, a spring is sleeved on the upper part of the positioning pin, a positioning disc is provided below the fixed disc, the positioning disc is set on the housing frame, and a positioning groove that matches the positioning pin is evenly opened on the positioning disc.

[0012] Preferably, the inner wall of the housing frame near the door is provided with a U-shaped sealing structure.

[0013] Preferably, the sealing structure includes a convex plate disposed on the housing frame, a convex strip disposed on one side of the convex plate, and an elastic sealing strip embedded in the convex strip.

[0014] Preferably, the inner side of the switch door is provided with a pressure strip that matches the sealing structure; When the pressing actuator applies a pressing force to the switch door, the sealing structure undergoes elastic deformation under the pressure of the pressure strip to fill the gap between the switch door and the housing frame.

[0015] The technical effects and advantages of this utility model are as follows: 1. This application utilizes a unique rotary pressing component, employing an eccentric wheel structure to convert the operator's rotational motion into a uniform radial pressing force. This pressure, precisely matched with the groove on the locking rod, acts stably on the door, causing the inner pressure strip to forcefully compress the elastic sealing strip on the housing frame. This active pressure locking method generates a locking force far greater than traditional snap-on door locks, ensuring sufficient elastic deformation of the elastic sealing strip. This fills all gaps between the door and the housing frame, fundamentally solving the leakage problem caused by poor sealing due to water pressure or long-term use, and greatly improving the product's sealing reliability and durability.

[0016] 2. The design of this application greatly optimizes user experience and operational safety. First, users can easily lock and unlock the door by simply turning the rotary handle, making the operation intuitive and effortless. Second, the positioning mechanism, consisting of a positioning pin and a positioning groove integrated on the rotary handle, provides clear tactile and audible feedback (a "click") at the locked or unlocked position, effectively preventing the door lock from accidentally loosening or opening due to vibration or other reasons during operation, ensuring safety during use, and combining convenience with high security.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Existing pet spa machine door lock structures suffer from insufficient sealing and decreased reliability after long-term use. Ordinary door locks struggle to provide continuous and even pressure, easily leading to gaps between the door and the frame, causing leaks during the spa process. This not only wastes water but can also damage the surrounding environment and internal electrical components, reducing the equipment's safety and lifespan.

[0021] To solve the above problems and achieve locking and sealing, please refer to [link / reference needed]. Figure 1-7 A sealed door lock structure for a pet spa machine that is easy to open and close includes a spa machine housing 1, the spa machine housing 1 including a housing frame 11 and a hinged door 2 on the housing frame 11, and further includes: Lock body 3 is fixedly installed on the housing frame 11 of the spa machine housing 1. The housing frame 11 is provided with a mounting cavity 12 for installing the lock body 3. The mounting cavity 12 is provided with a rotating pressing component 4. The rotary pressing assembly 4 includes a fixed plate 41 installed inside the mounting cavity 12. A rotating shaft 42 is rotatably inserted into the fixed plate 41, and two or more sets of pressing actuators 43 are installed in the middle of the rotating shaft 42. In this embodiment, each pressing actuator 43 includes an eccentric wheel 431 mounted on the rotating shaft 42. When the rotating shaft 42 rotates, the profile of the eccentric wheel 431 will generate a radial displacement from near to far, thereby generating pressing force. In order to better cooperate with the lock 5, a flange 432 is provided above each set of eccentric wheels 431 to increase the contact area and provide a guiding function. The flange 432 has an opening slot 433 at the farthest end near the shaft core of the rotating shaft 42 to provide space for the lock 5 to enter and exit in the unlocked state.

[0022] To ensure stable rotation and automatic reset of the rotating shaft 42, a positioning seat 44 for positioning the rotating shaft 42 is provided at the bottom of the mounting cavity 12. The rotating shaft 42 is inserted into the positioning seat 44, and a reset spring 45 is fitted at the bottom of the rotating shaft 42. A limit plate 46 is also provided on the outer side of the rotating shaft 42. One end of the reset spring 45 abuts against the positioning seat 44, and the other end abuts against the limit plate 46. When the external force is released, the elastic force of the reset spring 45 will drive the rotating shaft 42 and its linked components to automatically return to the initial unlocked position, facilitating the next operation.

[0023] Lock 5 is fixed on the switch door 2. Lock 5 works with pressing actuator 43 to lock and seal the switch door 2.

[0024] The lock body 3 and the lock 5 work together. The lock body 3 is integrated into the pre-set mounting cavity 12 of the housing frame 11, which protects the internal mechanical structure and makes the housing appearance flat and beautiful. The rotary pressing assembly 4 is the power core for realizing the locking function, and is stably installed in the mounting cavity 12 by the fixing plate 41. The operator drives the rotating shaft 42 to rotate by turning the external handle connected to the rotating shaft 42. The pressing actuator 43 installed on the rotating shaft 42 can convert the rotational motion into a radial pressing stroke when rotating. The flange 432 above the eccentric wheel 431 increases the contact area with the lock 5, making the pressure transmission more stable; while the opening groove 433 on it corresponds to the unlocking position, providing an interference-free channel for the lock 5 to enter and exit.

[0025] Specifically, the lock 5 includes an extension plate 51 fixed to the outer side of the switch door 2. A locking rod 52 is connected to one side of the extension plate 51. In order to achieve stable and reliable pressing contact, a groove 521 is provided below the outer end of the locking rod 52.

[0026] The extension plate 51 serves as a base and is securely fixed to the outer surface of the door 2 by screws or welding. The locking rod 52 extending from the extension plate 51 is the actual force-bearing component, and its length and position are precisely designed to ensure that it can accurately extend into the working range of the lock body 3 when the door is closed. When the eccentric wheel 431 rotates to the locked position, its protrusion is precisely embedded and pressed into the groove 521. This line contact engagement effectively prevents slippage and ensures that the pressing force is stably applied to the locking rod 52, thereby forcefully pulling the door 2 towards the housing frame 11.

[0027] Specifically, the housing frame 11 has a clearance groove 13, the position of which matches the position of the locking rod 52. When the door 2 is closed, the locking rod 52 is inserted into the clearance groove 13 and cooperates with the pressing actuator 43 to lock the door 2. When the user closes the door 2, the locking rod 52 can smoothly pass through the clearance groove 13, enter the mounting cavity 12, and reach its predetermined working position, preparing for the subsequent rotational locking action. When the eccentric wheel 431 rotates, because the outline of the eccentric wheel 431 is not a perfect circle, its rotation will cause its flange 432 to produce a radial displacement, thereby pressing the door shut.

[0028] A rotating handle 6 is connected to the top of the rotating shaft 42. A fixed disc 61 is mounted on the rotating handle 6, and a positioning sleeve 62 is mounted on the fixed disc 61. A positioning pin 63 is slidably inserted into the positioning sleeve 62. A spring 64 is fitted onto the upper part of the positioning pin 63. A positioning disc 7 is located below the fixed disc 61 and is mounted on the housing frame 11. A ring of positioning grooves 71, matching the positioning pins 63, is evenly formed on the positioning disc 7. These positioning grooves 71 always tend to insert downwards. When the user rotates the rotating handle 6 to the locked position, the positioning pin 63 will click into the corresponding positioning groove 71 under the action of the spring, thus firmly locking the handle at that angle. This not only provides clear operational feedback to the user but also greatly improves the stability and security of the locked state.

[0029] A U-shaped sealing structure 8 is provided on the inner wall of the housing frame 11 near the switch door 2. The sealing structure 8 includes a protruding plate 81 on the housing frame 11, a protruding strip 82 on one side of the protruding plate 81, and an elastic sealing strip 83 embedded in the protruding strip 82, which is made of a highly elastic and aging-resistant material such as silicone rubber. A pressure strip 21 matching the sealing structure 8 is provided on the inner side of the switch door 2. When the pressing actuator 43 applies a pressing force to the opening and closing door 2, the sealing structure 8 undergoes elastic deformation under the pressure of the pressure strip 21 to fill the gap between the opening and closing door 2 and the housing frame 11, thereby forming a reliable waterproof barrier, achieving a seal, and effectively preventing water leakage.
