Description

Technical Field

[0001] This utility model belongs to the field of high cabinet technology, specifically relating to a guide device and a high cabinet. Background Technology

[0002] In storage cabinets, tall cabinets, and other furniture or equipment, storage shelves are typically connected to the bottom of the cabinet cavity via a guide device. The guide device guides the shelf outwards or back in place along the outside of the cabinet, and is a key structure ensuring the smooth movement of sliding components. Traditional guide devices usually use a combination of rails and rollers to achieve the sliding function. However, existing technology has significant drawbacks. Specifically, gaps easily form between the rollers and the rails during sliding, causing the storage shelf connected to the sliding base to wobble from side to side, resulting in insufficient stability. Furthermore, after long-term use, the wear on the rollers and rails accelerates, further amplifying the lateral wobbling problem, affecting service life and user experience. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that the guide device of the existing tall cabinet causes the storage rack to sway left and right when sliding, and to provide a guide device and tall cabinet that makes the slide stable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A guiding device includes a housing and a slide block slidably mounted on the housing. The bottom wall of the housing is provided with a track extending along the sliding trajectory of the slide block, and the slide block is provided with rollers that roll in cooperation with the track. The housing has baffles extending upward on opposite sides, and the baffles are bent inward to form flanges extending towards the slide block. The slide block has transverse guide pulleys arranged horizontally and vertical guide pulleys arranged vertically on both sides. The transverse guide pulleys slide against the inner wall of the baffles, and the vertical guide pulleys slide against the bottom wall of the flanges.

[0005] Compared with existing technologies, the guiding device of this utility model, by setting baffles with flanges on both sides of the housing and arranging transverse guide pulleys and vertical guide pulleys on both sides of the slide, allows the transverse guide pulleys to slide against the inner wall of the baffles to limit horizontal displacement, and the vertical guide pulleys to slide against the bottom wall of the flanges to limit vertical displacement. This effectively eliminates left-right swaying and vertical gaps during the sliding process of the slide, significantly improving the stability and load-bearing uniformity of the storage rack. Multi-point rolling contact disperses friction loss, reducing local wear on the tracks and rollers and extending service life. The combination structure of the flanges and pulleys is simple and reliable, enhancing impact resistance while ensuring guiding accuracy and improving user experience.

[0006] Furthermore, the inner cavity of the housing extends longitudinally through both the front and rear sides of the housing, and the slide is installed inside the housing through either the front or rear opening of the inner cavity. By designing the inner cavity of the housing as an open structure that extends longitudinally, the slide can be flexibly installed from either the front or rear opening of the housing, ensuring a tight fit between the housing and the slide. This further guarantees the tight fit between the lateral guide pulley and the inner wall of the baffle, as well as the vertical guide pulley and the flange, significantly simplifying the assembly and disassembly process during assembly and maintenance.

[0007] Furthermore, the slide block has a receiving cavity with a bottom opening, and each side of the slide block has an outwardly bent portion. The transverse guide pulley is rotatably mounted on the bent portion. With this configuration, the bent portion is formed by bending through the slide block, which simplifies the production process of the slide block and improves product manufacturing efficiency.

[0008] Furthermore, the track includes a smooth section and a reset section connecting the end of the smooth section, the reset section extending obliquely downward; with this configuration, when the slide slides to the end of the housing to the reset section, it can use its own gravity to slide along the reset section to the end of the track, and can achieve self-reset at the end of the sliding process without the aid of external force, thus the guiding device has good performance.

[0009] Furthermore, the bottom wall of the housing is provided with a groove at the position corresponding to the reset section. The bottom of the groove is provided with a support surface that connects to the bottom wall of the housing at the front end and extends obliquely downward at the end. The reset section is provided on the support surface, and the roller makes rolling contact with the support surface. With this arrangement, the support surface can provide support to the roller, thereby playing the role of limiting the slide block to reset into place.

[0010] Furthermore, the bottom of the groove is also provided with a buffer surface that connects to the end of the support surface, and the buffer surface extends obliquely upward; by setting it in this way, the buffer surface at the end of the support surface can provide buffering and braking to the roller. Preferably, the slope of the buffer surface is greater than the slope of the support surface.

[0011] Furthermore, the cross-section of the track is set to be arc-shaped, and the roller has an arc groove in the middle that mates with the track; with this setting, the arc-shaped track and groove can improve the smoothness of the slide when it slides.

[0012] Furthermore, the rollers include two opposing first rollers located on the inner side of the front end of the slide block and two opposing second rollers located on the outer side of the rear end of the slide block. The bottom wall of the housing is provided with a track corresponding to each first roller and each second roller, and the first roller and the second roller respectively cooperate with the corresponding track. With this arrangement, the slide block can slide more smoothly by setting multiple rollers and tracks. The way the first rollers and second rollers at the front and rear ends are arranged inside and outside can make the tracks on the front and rear sides staggered, so as to extend the length of each track and thus extend the sliding trajectory of the slide block.

[0013] Furthermore, the slide block has grooves on both sides corresponding to the positions of the first roller, the second roller, and the transverse guide roller, and the second roller and the transverse guide roller are installed in the corresponding grooves. This design gives the slide block better structural strength and improves the reliability of the product.

[0014] Furthermore, the end of the housing is provided with a buffer, and the slide is provided with a stop for cooperating with the buffer.

[0015] Furthermore, the top of the slide is provided with a mounting seat, which has a mounting groove with an open top. The mounting groove is used for assembly and connection with the bottom frame of the storage rack. With this configuration, by providing a mounting seat with an open mounting groove on the top of the slide, the bottom frame of the storage rack can be quickly embedded and fixed, which simplifies the assembly process and enhances the connection stability between the slide and the storage rack. At the same time, the open groove design facilitates adjustment of the installation position or disassembly and maintenance, improving the applicability and ease of use of the overall structure.

[0016] A tall cabinet includes a cabinet body, cabinet doors, shelves, storage racks, and a transmission linkage. The cabinet body has a cabinet cavity with a front opening. The inner end of the cabinet door is rotatably connected to one side of the cabinet cavity via a door hinge. The upper and lower parts of the inner side of the cabinet door are respectively equipped with guide brackets, and the inner side of the guide brackets has guide grooves that open along the width direction of the cabinet door. The shelves are located on the inner side of the cabinet door, and one side is rotatably connected to the side wall of the cabinet body via a rotating component. The upper and lower side frames of the shelves can slide with the corresponding guide grooves. The storage racks are placed inside the cabinet cavity, with the lower part... The shelf is slidably connected to the bottom of the cabinet cavity via the guide device and can slide out or return to its original position relative to the guide device. The two ends of the transmission link are rotatably connected to the shelf and the storage shelf, respectively. When the cabinet door is open relative to the cabinet body, the shelf slides relative to the inside of the cabinet door under the pulling action of the rotating component, and drives the storage shelf to slide out relative to the door via the transmission link. When the cabinet door is closed relative to the cabinet body, the shelf slides relative to the outside of the cabinet door under the pushing action of the rotating component, and drives the storage shelf to return to its original position relative to the door via the transmission link.

[0017] Furthermore, the top of the slide is provided with a mounting base, and the mounting base has a mounting groove with an opening at the top. The bottom frame of the storage rack is connected to the mounting groove by screws. With this configuration, by providing a mounting base with an open mounting groove on the top of the slide, the bottom frame of the storage rack can be quickly embedded and fixed, which simplifies the assembly process and enhances the connection stability between the slide and the storage rack. At the same time, the open groove design facilitates adjustment of the installation position or disassembly and maintenance, improving the applicability and ease of use of the overall structure.

The slide seat 62 is provided with rollers that roll in cooperation with the track 63. The housing 61 is provided with baffles 67 extending upward on opposite sides. The baffles 67 are bent inward to form flanges 671 extending toward the slide seat 62. The slide seat 62 is provided with a horizontal guide pulley 69 arranged in the horizontal direction and a vertical guide pulley 68 arranged in the vertical direction on both sides. The horizontal guide pulley 69 slides against the inner wall of the baffle 67, and the vertical guide pulley 68 slides against the bottom wall of the flange 671.

[0027] Compared with the prior art, the guide device 6 of this utility model has baffles 67 with flanges 671 on both sides of the housing 61, and horizontal guide pulleys 69 and vertical guide pulleys 68 respectively on both sides of the slide block 62. The horizontal guide pulleys 69 slide against the inner wall of the baffles 67 to limit horizontal displacement, and the vertical guide pulleys 68 slide against the bottom wall of the flanges 671 to limit vertical displacement. This effectively eliminates the left and right swaying and vertical gaps during the sliding process of the slide block 62, and significantly improves the stability and load uniformity of the storage rack 4. The multi-point rolling contact disperses friction loss, reduces local wear of the track 63 and rollers, and extends service life. The cooperation structure between the flanges 671 and the pulleys is simple and reliable, which enhances the impact resistance while ensuring the guiding accuracy and improving the user experience.

By designing the inner cavity of the housing 61 as an open structure that extends longitudinally, the slide 62 can be flexibly installed from either the front or rear opening of the housing 61, ensuring a tight fit between the housing 61 and the slide 62. This further guarantees a tight fit between the transverse guide pulley 69 and the inner wall of the baffle 67, as well as between the vertical guide pulley 68 and the flange 671, significantly simplifying the assembly and disassembly process during assembly and maintenance.

[0031] See Figures 3 to 6 In one embodiment, the bottom wall of the housing 61 is provided with a groove 65 at the position corresponding to the reset section 632. The bottom of the groove 65 is provided with a support surface 651 with the front end connected to the bottom wall of the housing 61 and the end extending obliquely downward. The reset section 632 is provided on the support surface 651, and the roller makes rolling contact with the support surface 651. With this arrangement, the support surface 651 can provide support to the roller, thereby playing the role of limiting the slide block 62 to reset into place.

The first rollers 642 and the second rollers 643 respectively cooperate with the corresponding track 63. With this arrangement, the slide block 62 can slide more smoothly by setting multiple rollers and tracks 63. The way the first rollers 642 and the second rollers 643 at the front and rear ends are arranged inside and outside can make the tracks 63 on the front and rear sides staggered, so as to extend the length of each track 63, thereby extending the sliding trajectory of the slide block 62.
