Technical Field
[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background Art
[0002] A freezer is a refrigeration device used to store food, drinks and other items. It reduces the internal temperature through the evaporation and condensation of refrigerant, thereby maintaining the freshness and taste of food. Freezers are widely used in homes, supermarkets, restaurants and other places. Freezers are generally opened or closed by sliding doors. Existing refrigerator sliding door limiting methods generally include using springs to return the door body, setting a magnetic device or adding a tilting device in the door frame guide rail.
[0003] However, in the existing limit method for sliding doors of refrigerators, if a spring is used to return the door body, the sealing performance of the refrigerator can be guaranteed, but the spring is prone to insufficient elasticity and failure after long-term use; if a magnet device is used, once people use too much force when closing the door, the magnet contact time may be too short and it may not work, causing the door body to rebound and the refrigerator to open externally; if a tilting device is added to the inner guide rail of the door, a large space requirement is required, and a large number of components need to be modified to achieve it, which is difficult to install later; therefore, how to effectively and reliably realize the limit function of the sliding door of the refrigerator is still a problem to be solved. Utility Model Content
[0004] Based on this, in order to solve the problem of how to effectively and reliably realize the limit function of the existing refrigerator sliding door, one object of the present utility model is to provide a refrigerator, and its specific technical solution is as follows:
[0005] A refrigerator comprises a cabinet body, a cabinet door and a limiting device, wherein the cabinet body is provided with a door frame guide rail; the cabinet door is slidably connected to the door frame guide rail, and a movable wheel is provided at the bottom of the cabinet door; the limiting device is arranged in the door frame guide rail, and the limiting device comprises a limiting plate, and a limiting hole is provided on the limiting plate. When the cabinet door is closed, the movable wheel abuts against the limiting hole accordingly.
[0006] Furthermore, the limiting device includes a locking piece, a first locking hole is provided on the limiting plate, a second locking hole is provided on the door frame guide rail, the first locking hole and the second locking hole are provided correspondingly, and the locking piece is detachably connected to the first locking hole and the second locking hole in sequence.
[0007] Furthermore, the limiting plate is arranged at one end of the door frame guide rail, the first locking hole is arranged at the end of the limiting plate close to the cabinet side wall, and the limiting hole is arranged at the end of the limiting plate away from the cabinet side wall.
[0008] Furthermore, an anti-collision protrusion is provided at one end of the door frame guide rail away from the limiting plate, and the anti-collision protrusion is fixedly connected to the door frame guide rail.
[0009] Furthermore, the thickness of the limiting plate is set to 2 mm.
[0010] Furthermore, the limiting plate is configured as a stainless steel plate.
[0011] Furthermore, the width of the limiting hole is set to 15 mm.
[0012] Furthermore, the locking member is configured as a stainless steel self-tapping screw.
[0013] Furthermore, the width of the limiting plate is equal to the width of the door frame guide rail.
[0014] Furthermore, a handle is provided on the cabinet door, and all transition angles on the handle are rounded transitions.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the refrigerator of the present invention sets a limit device in the door frame guide rail. When the cabinet door is closed, the movable wheel abuts against the limit hole, ensuring that the cabinet door can accurately stay in the closed position, realizing an effective limit function, which not only improves the sealing of the refrigerator, but also prevents food spoilage, energy waste and even safety hazards caused by accidental opening of the cabinet door.

[0030] like Figure 1-Figure 7As shown, a refrigerator in one embodiment of the present invention includes a cabinet body 1, a cabinet door 3 and a limiting device 4. The cabinet body 1 is provided with a door frame guide rail 2; the cabinet door 3 is slidably connected to the door frame guide rail 2, and a movable wheel 31 is provided at the bottom of the cabinet door 3; the limiting device 4 is arranged in the door frame guide rail 2, and the limiting device 4 includes a limiting plate 41. The limiting plate 41 is provided with a limiting hole 411. When the cabinet door 3 is closed, the movable wheel 31 abuts against the limiting hole 411. By arranging the limiting device 4 in the door frame guide rail 2, when the cabinet door 3 is closed, the movable wheel 3 1 corresponds to the limiting hole 411, ensuring that the cabinet door 3 can accurately stay in the closed position, realizing an effective limiting function, which not only improves the sealing of the refrigerator, but also prevents food spoilage, energy waste and even safety hazards caused by accidental opening of the cabinet door 3. At the same time, the precise docking of the movable wheel 31 with the limiting hole 411 reduces the impact and vibration of the cabinet door 3 during the closing process, thereby reducing the wear and tear on the cabinet door 3, the door frame guide rail 2 and the limiting device 4, which helps to extend the overall service life of the refrigerator and reduce the frequency of maintenance and replacement of parts.
[0031] As a preferred embodiment of the present invention, it may also have the following additional technical features: the limiting device 4 includes a locking member 42, a first locking hole 412 is provided on the limiting plate 41, and a second locking hole 21 is provided on the door frame guide rail 2. The first locking hole 412 is corresponding to the second locking hole 21, and the locking member 42 is detachably connected to the first locking hole 412 and the second locking hole 21 in turn. By passing the locking member 42 through the first locking hole 412 on the limiting plate 41 and the second locking hole 21 on the cabinet body 1 in turn and realizing detachable connection, a stable structure is formed, which enhances the positioning of the limiting device 4 in the door frame guide rail 2. The fixation effectively prevents the limit device 4 from moving or shaking in the door frame guide rail 2, and can also ensure that the cabinet door 3 can be accurately aligned and maintained in the predetermined position when closed; since the connection between the locking member 42 and the first locking hole 412 and the second locking hole 21 is detachable, during long-term use, if a component is worn or damaged, it can be easily replaced, thereby extending the overall service life of the limit device 4; in addition, the detachable connection also allows the locking force to be adjusted to adapt to different usage environments and needs. In this embodiment, the locking member 42 is set to a stainless steel self-tapping screw.
[0032] As a preferred embodiment of the present invention, it may also have the following additional technical features: the limiting plate 41 is arranged at one end of the door frame guide rail 2, the first locking hole 412 is arranged at the end of the limiting plate 41 close to the side wall of the cabinet body 1, and the limiting hole 411 is arranged at the end of the limiting plate 41 away from the side wall of the cabinet body 1. Since the limiting hole 411 is located at the end away from the side wall, the contact between the pulley and the limiting plate 41 is smoother when abutting, reducing the generation of friction and noise, and there is no need to pass through the locking member 42, thereby ensuring the quality of the locking member 42 and extending its service life.
[0033] As a preferred embodiment of the present invention, it may also have the following additional technical features: an anti-collision protrusion 22 is provided at one end of the door frame guide rail 2 away from the limiting plate 41, and the anti-collision protrusion 22 is fixedly connected to the door frame guide rail 2, which can effectively prevent the cabinet door 3 from directly hitting the cabinet body 1 due to excessive force during the opening process, causing damage to the cabinet body 1 or the cabinet door 3.
[0034] As a preferred embodiment of the present invention, it may also have the following additional technical features: the thickness of the limiting plate 41 is set to 2 mm. In this embodiment, the thickness of 2 mm is neither too thick to affect the rolling of the movable wheel 31 nor too thin to be unable to withstand the pressure of the movable wheel 31. It provides a suitable gap so that the movable wheel 31 can easily roll on the limiting plate 41, reducing friction and resistance, and ensuring the smooth opening and closing of the cabinet door 3; in addition, in this embodiment, the limiting plate 41 is set to a stainless steel plate. In an environment such as a refrigerator that needs to be frequently exposed to water vapor and possible corrosive substances, the stainless steel limiting plate 41 can maintain its surface finish and structural integrity for a long time, extend its service life, and can withstand the friction and wear generated by the movable wheel 31 during long-term rolling. When the sliding door of the refrigerator is frequently opened and closed, it can still maintain the stability and accuracy of its limiting function.
[0035] As a preferred embodiment of the present invention, it may also have the following additional technical features: the width of the limiting hole 411 is set to 15 mm, so that the movable wheel 31 has a certain movable space in the limiting hole 411. Sufficient movable space can reduce the direct contact and friction between the movable wheel 31 and the edge of the limiting hole 411, thereby reducing the wear rate.
[0036] As a preferred embodiment of the present invention, it may also have the following additional technical features: the width of the limiting plate 41 is equal to the width of the door frame guide rail 2, and the limiting plate 41 can fit tightly on the door frame guide rail 2 to form a stable support structure, reducing the possibility of the limiting plate 41 swinging left and right when subjected to force, preventing the limiting plate 41 from swinging left and right and failing, thereby improving its stability.
[0037] As a preferred embodiment of the present invention, it may also have the following additional technical features: a handle 32 is provided on the cabinet door 3, and all transition corners on the handle 32 are rounded transitions. When opening and closing the cabinet door 3, it effectively prevents the user from being scratched or stabbed when grasping the handle 32. The handle 32 with rounded transitions is more comfortable when grasped, avoiding the pressure on the fingers caused by sharp edges.
[0038] When the door 3 is fully opened, the anti-collision protrusion 22 at one end of the door frame guide rail 2 away from the limiting plate 41 plays a buffering role to prevent the door 3 from hitting the cabinet body 1; when the door 3 needs to be closed, the user pushes the door 3 to move in the closing direction, and the movable wheel 31 continues to roll in the door frame guide rail 2 until it approaches the limiting plate 41. When the movable wheel 31 corresponds to the limiting hole 411 on the limiting plate 41, the movable wheel 31 accurately contacts the limiting hole 411, realizing accurate limiting of the door 3. At this time, the door 3 is tightly fitted on the door frame, thereby improving the sealing of the refrigerator and preventing cold air from leaking out and food from spoiling.
[0039] The refrigerator of this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the refrigerator can ensure that the cabinet door 3 can accurately stay in the predetermined position when closed, thereby improving the sealing of the refrigerator, helping to reduce the leakage of cold air, maintaining the temperature inside the refrigerator stable, improving the refrigeration efficiency, and reducing energy consumption.
