Description

Technical Field

[0001] This utility model relates to the field of drawer guide rail technology, and more specifically to a drawer guide rail mechanism for refrigerators. Background Technology

[0002] With the development of refrigeration technology and materials science, refrigerator design and manufacturing technology have continued to advance. In order to improve the convenience and safety of refrigerators, manufacturers have begun to develop more advanced drawer guide mechanisms. Through precise guidance and positioning, the guide mechanism helps to maintain a tight fit between the refrigerator drawer and the cabinet, thereby improving the refrigerator's sealing performance. This helps to reduce cold air leakage and improve the refrigerator's energy efficiency and preservation effect.

[0003] Existing refrigerator drawers, due to their integrated design, cannot be easily disassembled when a thorough cleaning of the inside is required. While this design ensures the overall aesthetics and structural stability of the refrigerator to some extent, it brings considerable trouble to daily cleaning. Users often have to wipe and remove stains and debris from the inside through limited openings or gaps, which not only increases the difficulty of cleaning but also makes it difficult to achieve a thorough cleaning.

[0004] Furthermore, these refrigerator drawers typically use a sliding connection for smooth opening and closing. However, this design makes the connection points prone to loosening or damage due to frequent friction and wear during long-term use. This is especially true when applying force to the drawer, such as by pushing or pulling it quickly or placing excessively heavy items, which exacerbates the wear at the connection points and further shortens the drawer's lifespan. Therefore, this design flaw not only affects the user experience but also increases maintenance and replacement costs.

[0005] To address the aforementioned problems, this application provides a guide rail mechanism for a refrigerator drawer. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a guide rail mechanism for refrigerator drawers to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a guide rail mechanism for a refrigerator drawer, including a drawer assembly and disassembly / assembly assemblies installed on both sides of the drawer assembly, wherein a sliding assembly is installed on the disassembly / assembly assemblies, and a buffer assembly and an auxiliary support assembly are installed on the sliding assembly;

[0008] Preferably, the drawer assembly includes a main drawer and an auxiliary hook slot, wherein the main drawer is equipped with disassembly components on both sides, and the main drawer has an auxiliary hook slot on the front side.

[0009] Preferably, the disassembly assembly includes a mounting plate, a slide rail, a limiting post, a knob, a cylindrical groove, and a locking block. The mounting plate is disposed on both sides of the main drawer. The mounting plate has a slide rail and a cylindrical groove. The limiting post is fixedly installed on both sides of the front end of the main drawer and engages with the slide rail. The knob is disposed on both sides of the inner wall of the main drawer and moves through the main drawer. The end of the knob away from the mounting plate is fixedly connected to the locking block. The locking block rotates and engages with the cylindrical groove. At this time, the locking block can be disengaged by turning the knob. Then, the main drawer and the components fixedly installed on the main drawer can be pulled out along the engagement axis between the limiting post and the slide rail.

[0010] Preferably, the sliding assembly includes a slider, a limiting groove, a first pulley, a rotating roller, a fixed plate, and a partition. The slider is disposed on both sides of the main drawer and fixedly installed on the side of the mounting plate away from the main drawer. Limiting grooves are provided on the upper and lower sides of the slider. The first pulleys are evenly distributed and engaged in the limiting grooves. The first pulleys are rotatably engaged with the rotating rollers. The rotating rollers are fixedly installed on the side wall of the fixed plate. The partition is disposed on the upper and lower sides of the first pulleys and fixedly installed on the side wall of the fixed plate. When the auxiliary hook groove is pulled, under the action of the rotational engagement between the rotating rollers and the first pulleys, the disassembly and assembly components installed on both sides of the main drawer drive the sliders to move along the engagement axis between the first pulleys and the limiting grooves.

[0011] Preferably, the buffer assembly includes a buffer groove, a first buffer block, a buffer spring, a buffer pad, and a second buffer block. The slider has a buffer groove, the first buffer block is fixedly engaged with the rear end of the buffer groove, the buffer spring is disposed in the buffer groove, and one end of the spring is fixedly connected to the first buffer block and the other end is fixedly connected to the buffer pad. The second buffer block is fixedly installed on the front side of the fixed plate and slidably connected to the buffer groove. When the main drawer is pulled out to the bottom, the second buffer block fixedly installed on the fixed plate squeezes the buffer pad and, under the action of the buffer spring, applies a force in the opposite direction to the slider and the main drawer disposed between the sliders.

[0012] Preferably, the auxiliary support assembly includes a sleeve, a locking post, a compression spring, a connecting block, a connecting rod, and a second pulley. The sleeve is disposed on both sides of the bottom of the main drawer and fixedly installed below the partition. The locking post movably locks onto the sleeve. The compression spring is disposed between the sleeve and the locking post and sleeved on the locking post. The connecting block is fixedly installed at the lower end of the locking post. The connecting rod is fixedly installed between the two connecting blocks. The second pulley is rotated in pairs and sleeved on the connecting rod. At this time, the second pulley disposed below the main drawer drives the locking post through the connecting rod and provides a certain support force to the main drawer under the action of the compression spring, preventing the main drawer and the components fixedly installed on the main drawer from damaging the first pulley disposed on the lower side.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] After prolonged use, the locking block can be released from the cylindrical groove by turning the knob. At this point, the main drawer can be pulled out along the locking axis between the limiting post and the slide groove. This design facilitates cleaning the inside of the drawer. When storing frozen items, the drawer can be pulled out by pulling the auxiliary hook groove. Under the action of the rotational engagement between the rotating roller and the first pulley, the disassembly and assembly components installed on both sides of the main drawer drive the slider to move along the locking axis between the first pulley and the limiting groove, thereby pulling out the main drawer. This design effectively reduces the wear of the sliding locking parts during use and improves the service life of the device. Attached Figure Description
