[0052] Embedded devices can be refrigeration equipment, cleaning appliances, cooking appliances, etc. There are many types of embedded devices. Taking refrigeration equipment as an example, refrigeration equipment can be refrigerators, freezers, display cabinets, wine cabinets, etc. When installing embedded devices, the embedded devices are decorated with cabinet panels that match the style. It is necessary to consider the installation of opening and closing devices connected to the embedded devices, such as drawers or doors and cabinet panels. In the following embodiments, the opening and closing devices are described using drawers and doors as examples. Figures 1 to 14 As shown, the cabinet panel is installed on the front side of the embedded device. The cabinet panel can decorate and protect the embedded device. The front side here can be understood as the drawer and door body in the embedded device are in a closed state, and the surface facing the user is the front side. The front side of the drawer body or the door body is connected to the cabinet panel.

[0053] refer to Figure 2 and Figure 4As shown, an embodiment of the first aspect of the utility model provides an opening and closing device for a refrigeration device, comprising a device body 200 and an adjusting component 400, wherein a support and limiting portion 300 is connected to the front side of the device body 200, and the direction corresponding to the smaller length of the width and height of the device body 200 is a preset direction, and the support and limiting portion 300 is provided with a slide extending along the preset direction; the adjusting component 400 is used to connect the cabinet panel 500, and the adjusting component 400 is slidably arranged on the slide, and the front side of the adjusting component 400 is limited by the support and limiting portion 300, and the adjusting component 400 includes at least two different adjusting portions 410, wherein one of the adjusting portions 410 is supported by the support and limiting portion 300, and the relative height of the device body 200 and the cabinet panel 500 is adjusted by switching the adjusting portion 410 supported by the support and limiting portion 300.

[0054] The device body 200 is connected to the support and limit portion 300, and the adjustment component 400 is installed on the cabinet panel 500. By installing the adjustment component 400 to the support and limit portion 300, the cabinet panel 500 can be installed on the front side of the device body 200. By adjusting the adjustment portion 410 supported by the support and limit portion 300 in the adjustment component 400, the height position of the cabinet panel 500 relative to the device body 200 can be adjusted. It should be noted that in the above embodiment, the opening and closing device does not include the cabinet panel 500, and the opening and closing device can be manufactured and sold independently. When the opening and closing device is in a closed state, the front side of the device body 200 is connected to the support and limit portion 300, and the support and limit portion 300 can be integrally formed with a part of the device body 200, or the support and limit portion 300 can be detachably connected to a part of the device body 200.

[0055] "The direction corresponding to the smaller length of the width and height of the device body 200 is the preset direction, and the support limit part 300 is provided with a slide extending along the preset direction." According to the width and height of the device body 200, the extension direction of the slide of the support limit part 300 is set. If the width of the device body 200 is smaller than the height, the preset direction is the width direction, and the slide of the support limit part 300 extends along the width direction. If the height of the device body 200 is smaller than the width, the preset direction is the height direction, and the slide of the support limit part 300 extends along the height direction.

[0056] refer to Figure 2As shown, taking the door body of a refrigeration equipment whose opening and closing device is an example, when the width of the door body is smaller than the height, the slide of the support limit part 300 on the front side of the door body extends in the width direction, and when other dimensions of the support limit part 300 remain unchanged, relative to the extension of the slide of the support limit part 300 in the height direction, the length of the support limit part 300 (the length in the extension direction of the slide of the support limit part 300 is defined as the length of the support limit part 300) is reduced, and the space occupied by the support limit part 300 on the front side of the door body is reduced. When the thickness of the door body remains unchanged, the influence of the support limit part 300 on the space of the thermal insulation layer of the door body is reduced, thereby ensuring the filling amount of the thermal insulation layer of the door body and the thermal insulation effect of the door body.

[0057] refer to Figure 4 As shown, taking a drawer of a refrigeration device as an example, when the height of the drawer is smaller than the width, the slide of the support limit part 300 on the front side of the drawer extends in the height direction, and when other dimensions of the support limit part 300 remain unchanged, relative to the extension of the slide of the support limit part 300 in the width direction, the length of the support limit part 300 (the length in the extension direction of the slide of the support limit part 300 is defined as the length of the support limit part 300) is reduced, and the space occupied by the support limit part 300 on the front side of the drawer is reduced. When the thickness of the front wall of the drawer remains unchanged, the influence of the support limit part 300 on the space of the insulation layer of the front wall of the drawer is reduced, thereby ensuring the filling amount of the insulation layer of the drawer and the thermal insulation effect of the drawer.

[0058] If the width and height of the device body 200 are equal or approximately equal, and approximately equal can be understood as the difference being within a set range, the support limit portion 300 is provided with a slideway extending in the width direction or the height direction.

[0059] Of course, in some cases, the height of the door body may be smaller than the width. At this time, the preset direction is the height direction. Similarly, the width of the drawer may be smaller than the height. At this time, the preset direction is the width direction.

[0060] The height direction is perpendicular to the width direction, and the vertical here can be vertical to form an angle of 90°, or it can be approximately vertical, forming an angle between 85-95°. The height direction can be perpendicular to the horizontal plane or approximately perpendicular to the horizontal plane. In other words, this embodiment does not make strict requirements on the height direction. For example, the angle between the height direction and the horizontal plane is between 85-95 degrees, which can be considered as the height direction. The width direction can be parallel to the horizontal plane or approximately parallel to the horizontal plane. There are no strict requirements on the width direction. For example, the angle between the height direction and the horizontal plane is between 0-10°, which can be considered as the width direction. The aforementioned non-strict requirements include manufacturing errors, design needs, etc.

[0061] "The adjusting component 400 is slidably disposed on the slide", the adjusting component 400 can slide along the extension direction of the slide, and the adjusting component 400 is installed in the extension direction of the slide. In some cases, the adjusting component 400 and the supporting limit portion 300 can also be positionally adjusted along the extension direction of the slide.

[0062] The cabinet panel 500 is adjusted in height relative to the device body 200. Position adjustment is achieved by adjusting the position of the adjustment part 410 supported by the support limit part 300 and switching the adjustment part 410 supported by the support limit part 300. “Different adjustment parts 410” can be understood as different distances from the outer edge of the adjustment part 410 to the installation center o of the first adjustment component 400. Based on the fact that the height position of the installation center o and the cabinet panel 500 remain unchanged, the distance from the outer edge of the adjustment part 410 to the installation center o is different, and the distance from the installation center to the support part 340 changes. Then, the outer edge of the adjustment part 410 is supported at a different height position from the support part 340, thereby achieving height position adjustment of the cabinet panel 500. The installation center o is located on the axis of rotation adjustment of the adjustment component 400. The installation center o can be understood as a virtual center, not the center of the adjustment component 400. Reference Fig.10 As shown, the inner and outer directions of the adjustment portion 410 can be understood as the inner side being closer to the installation center o and the outer side being farther from the installation center o.

[0063] The number of different adjustment parts 410 is equivalent to the number of adjustment gears in the height direction. If the adjustment component 400 is provided with four adjustment parts 410 and the number of different adjustment parts 410 is two, there are two adjustment positions. If the adjustment component 400 is provided with four adjustment parts 410 and the number of different adjustment parts 410 is four, there are four adjustment positions. When the adjustment component 400 is provided with four adjustment parts 410 and the number of different adjustment parts 410 is two, the other two adjustment parts 410 can have the same structure as one of the adjustment parts 410, or two of each adjustment part 410 can be provided. If a plurality of adjustment parts 410 of the adjustment component 400 are provided, when one of the adjustment parts 410 is deformed or damaged, the other adjustment part 410 can be switched to support the support limit part 300, so that the support and adjustment requirements can be met without replacing the adjustment component 400. Of course, if the adjustment component 400 is provided with two adjustment parts 410, the two adjustment parts 410 are provided to be different.

[0064] The opening and closing device may be equipped with an adjusting component 400 of the same size, or the opening and closing device may be equipped with at least two adjusting components 400 of different sizes. By replacing the adjusting component 400, the number of height adjustment gears is increased.

[0065] The support and limiting portion 300 at least limits the front position of the adjusting component 400 , and the rear position of the adjusting component 400 can be achieved through the surface of the support and limiting portion 300 or the device body 200 .

[0066] The opening and closing device of the refrigeration equipment of the embodiment of the utility model includes a door body or a drawer of the refrigeration equipment. At least two different adjustment parts 410 are set by the adjustment component 400. The different adjustment parts 410 are switched to support the support limit part 300, so as to adjust the height position of the cabinet panel 500. The direction of the slide of the support limit part 300 is determined according to the height and width of the opening and closing device, so as to minimize the space of the opening and closing device occupied by the support limit part 300, reduce the structural influence of the support limit part 300 on the opening and closing device, and ensure the function of the opening and closing device.

[0067] Among them, the length m of the slide groove extending along the preset direction of the support limit part 300 is less than the length n of the device body 200 along the preset direction. Generally, it is greater than half n / 2 of the length of the device body 200 along the preset direction, such as 0.6b≤m≤0.9b, to ensure the installation stability of the device body 200 and the cabinet panel 500 in the preset direction.

[0068] refer to Figure 2 and Figure 4 As shown, the device body 200 is provided with an end cover and a column 230. The left and right ends of the end cover are provided with columns 230. The columns 230 are divided into a left column 230 and a right column 230. The end cover is provided at the upper and lower ends of the column 230. The end cover is divided into an upper end cover 220 and a lower end cover 210.

[0069] Next, the support limiting portion 300 is described based on the preset direction being the width direction (which can also be understood as the left-right direction).

[0070] Understandably, reference Figure 2 and Figure 3 As shown, the support limit portion 300 includes a first limit portion 310 and a second limit portion 320 connected to the lower end of the first limit portion 310, the first limit portion 310 and the second limit portion 320 form a slide extending along the width direction, the first limit portion 310 is arranged at the front side of the second limit portion 320 and forms an angle with the second limit portion 320, the first limit portion 310 limits the front side of the adjusting component 400, and the second limit portion 320 supports one of the adjusting portions 410.

[0071] The first limiting portion 310 and the second limiting portion 320 extend in the width direction at the front side of the device body 200. The first limiting portion 310 and the second limiting portion 320 cooperate to form a slide extending in the width direction. The slide can be understood as a slide rail or a slide groove. The adjustment portion 410 can move in the width direction along the slide rail or the slide groove to install the adjustment component 400 in place, and can also adjust the position of the cabinet panel 500.

[0072] It can be understood that the upper surface of the second limiting portion 320 and the end surface of the adjusting portion 410 support each other. Compared with point contact or line contact, surface support can increase the contact area, provide better support stability and better load-bearing capacity, and help improve the connection stability between the cabinet panel 500 and the door body.

[0073] Understandably, reference Figure 3 As shown, the device body 200 is provided with an end cover (upper end cover and / or lower end cover), the first limit portion 310 and the second limit portion 320 extend along the end cover and are connected to the front side of the end cover, and the support limit portion 300 occupies the space on the front side of the end cover, which can reduce the impact on the volume of the thermal insulation layer in the device body 200. The first limit portion 310 and the second limit portion 320 are installed on the end cover, and the structure of the end cover is adaptively adjusted without affecting the structure of other components of the device body 200.

[0074] Of course, reference Figure 2 As shown, the device body 200 is provided with a column 230, and the first limiting portion 310 and the second limiting portion 320 are fixedly connected to the columns 230 at two left and right ends. The installation positions of the first limiting portion 310 and the second limiting portion 320 are flexible and can be adjusted according to actual conditions.

[0075] refer to Figure 3 As shown, when the upper end cover 220 is connected to the support and limit part 300, the front side of the upper end cover 220 is protruded to form a plurality of convex ribs 250, and the front end surface of the convex ribs 250 contacts and limits the rear end surface of the adjustment component 400, and the convex ribs 250 limit the adjustment component 400 at the rear, and the first limit part 310 limits the adjustment component 400 at the front, so as to ensure the stability of the adjustment component 400 in the front and rear directions. At this time, the support and limit part 300 does not need to be provided with a rear wall plate, which is equivalent to simplifying the structure of the support and limit part 300, and can also reduce the thickness of the support and limit part 300, thereby reducing the gap between the door body and the cabinet board 500.

[0076] In addition, the rib 250 can strengthen the strength of the end cover and ensure that the thickness of the end cover is not reduced. Based on the injection molding of the end cover, the front end surface of the rib 250 has good flatness, which makes the adjustment component 400 move more smoothly between the first limiting portion 310 and the end cover.

[0077] It can be understood that the upper end cover 220 is provided with a limiting surface, which limits at least one of the lower end, left end and right end of the first limiting portion 310 and the second limiting portion 320 to ensure that at least one end of the first limiting portion 310 and the second limiting portion 320 is positioned by the end cover, which is convenient for positioning and installation.

[0078] The upper end cover 220 is provided with a first limiting surface 260, and the bottom surfaces of the first limiting portion 310 and the second limiting portion 320 are limited by the first limiting surface 260. It can also be understood that the upper end cover 220 is provided with a sinking platform, and the first limiting portion 310 and the second limiting portion 320 are positioned and supported by the sinking platform, so as to facilitate the installation and positioning of the first limiting portion 310 and the second limiting portion 320.

[0079] It can also be understood that the upper end cover 220 is provided with a second limiting surface 270, and the left side or right side of the first limiting portion 310 and the second limiting portion 320 is limited by the second limiting surface 270. Two second limiting surfaces 270 can be provided, one limiting the left side of the first limiting portion 310 and the second limiting portion 320, and the other limiting the right side of the first limiting portion 310 and the second limiting portion 320.

[0080] The upper end cover 220 can be provided with a first limiting surface 260 and a second limiting surface 270 at the same time, and the lower side, left side and right side of the first limiting portion 310 are all limited, and the first limiting portion 310 can be accurately positioned and installed with the end cover. Similarly, the lower end cover 210 can be provided with at least one of the first limiting surface 260 and the second limiting surface 270.

[0081] The support limiter 300 can be fixedly connected to the end cover by the second fastener 350 , which is easy to install and has a simple structure.

[0082] It is understandable that the extension direction of the second limit portion 320 supports multiple adjustment components 400, and the minimum distances from different adjustment components 410 to the installation center of the adjustment component 400 are the same or different. Each adjustment component 400 is supported by the second limit portion 320, and the distances from the adjustment components 410 of each adjustment component 400 to the installation center can be the same or different, and each adjustment component 400 can be adjusted independently, and the adjustment is flexible.

[0083] Understandably, reference Figure 2 and Figure 3 As shown, an auxiliary limiting portion 600 is arranged above the supporting limiting portion 300. The structure of the auxiliary limiting portion 600 is the same as that of the supporting limiting portion 300. The auxiliary limiting portion 600 and the supporting limiting portion 300 are symmetrically arranged along a preset symmetry axis. The auxiliary limiting portion 600 and the supporting limiting portion 300 cooperate to double-limit the adjusting component 400 in the height direction, and the installation stability of the adjusting component 400 on the device body 200 is better.

[0084] It can be understood that the auxiliary limiting portion 600 and the supporting limiting portion 300 are spaced apart in the height direction, and it can be understood that the auxiliary limiting portion 600 cooperates with the supporting limiting portion 300 to form a slideway with a T-shaped longitudinal section, which can not only stabilize the limiting adjustment component 400, but also facilitate the connection between the adjustment component 400 and the cabinet board 500. The auxiliary limiting portion 600 and the supporting limiting portion 300 can be independent of each other or integrally formed.

[0085] When the adjustment component 400 includes an adjustment portion 410 and a body portion 420, the body portion 420 is used to connect the cabinet board 500, the outer ring of the body portion 420 is connected with the adjustment portion 410, the center of the body portion 420 is the installation center o, and the body portion 420 is connected to the cabinet board 500 through the space between the auxiliary limiting portion 600 and the support limiting portion 300. A spacing is set between the body portion 420 and the support limiting portion 300, the body portion 420 does not contact and support the support limiting portion 300, and the adjustment portion 410 cooperates with the support limiting portion 300 to support, reducing contact friction.

[0086] In the above-mentioned embodiments, the upper end cover 220 and the lower end cover 210 may each be provided with a set of adjustment components 400 and support limiter 300 to ensure the installation stability of the device body 200 and the cabinet board 500 in the height direction.

[0087] Below, based on the preset direction as the height direction, refer to Figures 4 to 9 As shown, the support limiting portion 300 is described.

[0088] Understandably, reference Figure 4 and Figure 6 As shown, the preset direction is the height direction, the support limiting portion 300 includes a blocking portion 330 and a supporting portion 340, the blocking portion 330 extends along the height direction and forms a slide extending along the height direction, the blocking portion 330 is arranged above the supporting portion 340, the blocking portion 330 is limited to the front side of the adjusting component 400, and the supporting portion 340 supports one of the adjusting portions 410.

[0089] The blocking portion 330 is provided with a slideway extending in the height direction, the upper end of the slideway is open, and the adjusting component 400 can slide along the slideway from the upper end of the blocking portion 330 to be supported by the supporting portion 340 .

[0090] It can be understood that the barrier portion 330 is connected to an adjustable component 400 which is movable in the width direction, and the adjustable component 400 can be moved and adjusted relative to the barrier portion 330 in the width direction. During the movement of the adjustable component 400, the supporting portion 340 supports the adjustable portion 410, and the barrier portion 330 limits the front position of the adjustable component 400.

[0091] In some cases, reference Fig. 9As shown, the barrier portion 330 is provided with a first slide 336 and a second slide 337 extending in the height direction. The first slide 336 is located in front of the second slide 337. The first slide 336 is connected to the second slide 337. The upper ends of the first slide 336 and the second slide 337 are open. The second slide 337 can be understood as an opening extending in the height direction opened on the front side of the barrier portion 330.

[0092] refer to Figure 4 and Figure 6 As shown, the blocking portion 330 can be understood as a vertical guide rail, which extends in the height direction, and an opening is provided at the upper end of the vertical guide rail to facilitate the adjustment component 400 to enter the vertical guide rail from the opening, so as to achieve the connection and limit of the adjustment component 400 and the blocking portion 330. When the vertical guide rail is provided with a slideway with a T-shaped groove in cross section, the first slideway 336 and the second slideway 337 cooperate to form a slideway with a T-shaped groove in cross section, and the adjustment component 400 is passed through the opening on the front side of the slideway to be connected with the cabinet board 500.

[0093] refer to Figure 8 As shown, when the adjusting component 400 includes a main body portion 420 connected to the adjusting portion 410, the main body portion 420 is used to connect the cabinet panel 500, and the main body portion 420 is movably connected to the first slide 336, and the main body portion 420 is connected to the cabinet panel 500 through the first slide 336; the adjusting portion 410 is movably connected to the second slide 337, and the front side of the adjusting portion 410 is limited by the wall panel of the second slide 337. The connection method between the adjusting component 400 and the cabinet panel 500 is simple and can ensure that the adjusting component 400 can be stably moved and adjusted in all directions in the blocking portion 330.

[0094] refer to Figure 8 As shown, the main body 420 protrudes forward from the adjusting part 410, and the blocking part 330 includes a first limiting plate 331 and a second limiting plate 332 which are arranged opposite to each other in the left-right direction and have a spacing therebetween. In the left-right direction, the main body 420 can move between the first limiting plate 331 and the second limiting plate 332 and be limited by the first limiting plate 331 and the second limiting plate 332. By limiting the left-right direction by the main body 420, the adjusting part 410 can be spaced apart from the wall plate of the second slideway 337 in the left-right direction, thereby reducing the contact friction of the adjusting part 410 when it moves in the height direction in the blocking part 330.

[0095] Understandably, reference Figure 8As shown, the end of the first limiting plate 331 facing away from the second limiting plate 332 is connected to the third limiting plate 333, the third limiting plate 333 and the first limiting plate 331 form an angle (such as perpendicular), the end of the second limiting plate 332 facing away from the first limiting plate 331 is connected to the fourth limiting plate 334, the fourth limiting plate 334 and the second limiting plate 332 form an angle (such as perpendicular), the third limiting plate 333 and the fourth limiting plate 334 are connected by a connecting plate 335, the first limiting plate 331 and the second limiting plate 332 form a second slide 337, and the third limiting plate 333 and the fourth limiting plate 334 form a first slide 336. The third limiting plate 333 and the fourth limiting plate 334 play a role in protecting the adjustment part 410 in the left-right direction. The distance between the first limiting plate 331 and the connecting plate 335 and the distance between the second limiting plate 332 and the connecting plate 335 are equal and are greater than or equal to the thickness of the adjusting portion 410 .

[0096] It can be understood that, when the first limiting plate 331 is in contact with the main body 420 for limiting, the third limiting plate 333 is in contact with or has a gap with the adjusting part 410 on the same side, and in the left-right direction, the first adjusting component 400 and the supporting limiting part 300 are mutually limited by the main body 420 and the first limiting plate 331. Similarly, when the second limiting plate 332 is in contact with the main body 420 for limiting, the fourth limiting plate 334 is in contact with or has a gap with the adjusting part 410 on the same side.

[0097] The distance from the fourth limiting plate 334 to the third limiting plate 333 is the first distance L1, the distance from the first limiting plate 331 to the second limiting plate 332 is the second distance L2, the maximum length of the main body 420 along the left-right direction is the third distance L3, and the maximum vertical distance from the edge of the adjustment part 410 to the installation center of the main body 420 along the left-right direction is the second distance L4, L1-2L4≥L2-L3. In the process of adjusting the adjustment part 410 supported by the support part 340, different adjustment parts 410 are supported by the support part 340, and the adjustment parts 410 limited by the support limit part 300 are different. By limiting the size relationship between the first adjustment part 400 and the support limit part 300, no matter which adjustment part 410 is supported by the support part 340, the first adjustment part 400 is limited in the left and right directions through the main body 420 and the support limit part 300 to avoid interference between the adjustment part 410 and the support limit part 300 (the third limit plate 333 and the fourth limit plate 334).

[0098] In some other cases, different from the above embodiments, the left column is connected to a left partition part, and the right column is connected to a right partition part, and both the left partition part and the right partition part are provided with relative openings (not shown in the figure), and the left partition part limits the adjusting component 400 to the left, that is, limits the cabinet panel 500 to the left, and the partition part limits the adjusting component 400 to the right, that is, limits the cabinet panel 500 to the right, and the left partition part and the right partition part cooperate to achieve limitation in the left and right directions, and a single partition part cannot achieve limitation in both left and right directions, which can simplify the structure of a single partition part 330, and then simplify the structure of the device body 200.

[0099] It is understandable that the device body 200 is provided with a lower end cover 210, and the lower end cover 210 is formed with a support portion 340. The lower end cover 210 supports the adjustment portion 410, and the top surface of the lower end cover 210 is fully utilized, which can reduce the number of parts.

[0100] Understandably, reference Figures 4 to 6 As shown, the upper end of the support portion 340 forms a support surface 341, and the support surface 341 is supported below the adjustment portion 410 and supported with the adjustment portion 410, and the support stability is good. The support portion 340 is a support plate arranged at the upper end of the end cover, and the upper surface of the support plate forms a support surface 341. The front end of the support plate protrudes from the front end of the mounting portion 240 by a preset length to provide an installation space for the support limit portion 300, and the support plate can also support the support limit portion 300.

[0101] Of course, the column 230 may also be formed with a support portion 340. The column 230 has guiding, limiting and supporting functions. The functions of the column 230 are more diverse, which helps to simplify the structure of the door body.

[0102] Understandably, reference Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the column 230 is integrally formed with a baffle 330, and the column 230 includes a left column and a right column. At least one of the left column and the right column is integrally formed with the baffle 330, which can reduce the number of parts. The column 230 has multiple functions, which can simplify the assembly of the device body 200. When the lower end cover 210 is provided with a support part 340, the device body 200 only adds an adjustment component 400, which can reduce the number of accessories of the device body 200 and simplify the installation. The device body 200 is provided with an end cover, and the column 230 is connected to the end cover through the baffle 330. The connection method between the column 230 and the end cover is simple.

[0103] Understandably, reference Figures 4 to 7As shown, the device body 200 is provided with an upper end cover 220, and the upper end cover 220 and the lower end cover 210 are detachably connected to the baffle 330, and the baffle 330 can be disassembled and replaced as needed. At this time, the baffle 330 and the column 230 can be integrally formed or independent of each other.

[0104] The end cap is provided with a mounting portion 240, and the barrier portion 330 is fixedly connected to the mounting portion 240. The end cap can be fixed to the barrier portion 330 by connecting with a second fastener 350, by snap connection, or by bonding, and the fixing method can be selected according to needs.

[0105] It is also understandable that reference Figure 7 and Figure 8 As shown, the mounting portion 240 is provided with at least one of a first stop portion 241 and a second stop portion 242. The first stop portion 241 is limited in the front-to-rear direction of the partition portion 330, and the second stop portion 242 is limited in the left-to-right direction of the partition portion 330. The partition portion 330 is limited in the front-to-rear direction and / or left-to-right direction by at least one of the upper and lower end covers 210 to ensure the installation stability of the support limit portion 300 in the drawer body.

[0106] The first stopper 241 is a guide rail that can be limited in the front-rear direction, and the guide rail can limit the support limiter 300 through a guide block or a guide groove; similarly, the second stopper 242 is a guide rail that can be limited in the left-right direction, and the guide rail can limit the support limiter 300 through a guide block or a guide groove. Figure 8 As shown, the first stopper 241 and the second stopper 242 are both provided with guide grooves, and the opening directions of the guide grooves are different. The first stopper 241 opens toward the upper side and the right side, and the second stopper 242 opens toward the upper side and the front side.

[0107] It should be noted that the mounting portion 240 is provided with at least one of a first stop portion 241 and a second stop portion 242, and the mounting portion 240 and the partition portion 330 are connected via a second fastener 350. These two connection methods can be selected one by one, and can also be doubly fixed to ensure the installation stability of the support limit portion 300.

[0108] When the upper and lower end covers cooperate, the baffle part 330 can be limited in the up and down directions, left and right directions, and front and back directions. During the installation process, one of the upper and lower end covers can be connected to the baffle part 330 first, and then the other one of the upper and lower end covers can be connected to the baffle part 330.

[0109] Understandably, reference Figure 4As shown, the height direction of the support limiter 300 can be slidably connected to multiple adjustment components 400. Each adjustment component 400 is equipped with a support portion 340, and the adjustment portion 410 of each adjustment component 400 can be supported by the support portion 340; or, a support portion 340 is provided at the lower end of the barrier portion 330, and the adjustment portion 410 of the lowermost adjustment component 400 is supported by the support portion 340.

[0110] In the above-mentioned embodiments, a set of adjusting components 400 and supporting limit parts 300 may be respectively provided at the left and right ends of the end cover to ensure the installation stability of the device body 200 and the cabinet board 500 in the width direction.

[0111] Below, reference Figures 10 to 14 As shown, the adjustment component 400 is described.

[0112] It is understandable that the adjustment parts 410 are located on different sides of the adjustment component 400. When the adjustment component 400 is provided with four sides, the adjustment parts 410 are provided on at least two sides, so as to facilitate distinguishing each adjustment part 410 and accurately adjusting to the target position.

[0113] The adjusting component 400 is a quadrilateral adjusting component, and the outer contour of the adjusting component 400 is provided with four sides, and the adjusting parts 410 are provided on different sides of the adjusting component 400. The adjusting parts 410 are provided on two sides, three sides or four sides of the adjusting component 400, and the adjusting parts 410 are located on different sides of the adjusting component 400. The number of the adjusting parts 410 is less than or equal to four and greater than or equal to two, and at least two adjusting parts 410 are different.

[0114] The quadrilateral adjustment component can be a quadrilateral structure or a nearly quadrilateral structure. The outer contour of the quadrilateral adjustment component 400 includes four side faces, each of which can be straight or curved. The shape of each face is not limited, such as at least one of the four sides extends along a straight line, and at least one side extends along an arc curve. The shape of the adjustment component 400 can be a rectangle, trapezoid, parallelogram, or rhombus. The specific shape of the adjustment component 400 is not limited and will not be listed here. Adjacent side faces of the adjustment component 400 can be chamfered. If the shape of the adjustment component 400 is a square, the installation center does not coincide with the center of the square to ensure that the adjustment component 400 is provided with at least two adjustment parts 410. Among them, Fig.10 The installation center o is marked by a black dot in the figure, and the distances from different adjustment parts to the installation center are marked as a1, a2, a3 and a4 in the figure.

[0115] It is understandable that when the adjustment component 400 includes a body 420 connected to the adjustment part 410, the body 420 is used to connect the cabinet board 500. The adjustment part 410 is connected to the outer edge of the body 420, and the adjustment part 410 cooperates with the body 420 so that the outer contour of the adjustment component 400 is a quadrilateral.

[0116] The outer edge here can be understood as the edge of the adjusting component 400 away from the installation center. The inner and outer directions of the adjusting component 400 can be understood as the inner side close to the installation center and the outer side away from the installation center.

[0117] It is understandable that the minimum distance from the outer edge of different adjustment parts 410 to the installation center of the main body 420 is different. The main body 420 is connected to the cabinet panel 500, and the installation center of the adjustment component 400 is located in the main body 420, which is convenient for positioning and installation of the adjustment component 400 and the cabinet panel 500.

[0118] In some cases, the distance from the edge of the main body 420 to the installation center is equal, the outer contour shape of the main body 420 can be a circle, an equilateral triangle, a square, or other regular polygons, and the installation center is the center of the main body 420.

[0119] Understandably, reference Figures 10 to 14 As shown, three or four adjustment parts 410 are sequentially arranged on the outer circle of the main body 420 , the adjustment part 410 at the lower end is supported by the support limit part 300 , and the adjustment part 410 at the left end and / or the right end can be limited by the support limit part 300 .

[0120] When four adjusting parts 410 are sequentially arranged on the outer ring of the main body 420, the maximum vertical distance between two adjusting parts 410 arranged opposite to each other in the height direction is a first length, and the maximum vertical distance between two adjusting parts 410 arranged opposite to each other in the left-right direction is a second length, and the first length is equal to the second length. Fig.10 After the adjustment part 410 supported by the support and limiting part 300 is switched, it is ensured that the adjustment part 410 in the left and right directions will not interfere with the limiting part.

[0121] Understandably, reference Fig.10 As shown, two different adjustment parts 410 are provided on opposite sides of the main body 420; or, referring to Fig.12 As shown, two different adjusting parts 410 are arranged on adjacent sides of the main body 420. The positions of the different adjusting parts 410 are flexible and can be selected according to needs.

[0122] Understandably, reference Fig.10 and Fig.12As shown, the adjustment part 410 is provided with an adjustment distance mark 430, and the minimum distance to the installation center is called the reference distance. The adjustment distance mark 430 of the adjustment part 410 corresponding to the reference distance is 0 mm, and the difference between the distance from the other adjustment parts 410 to the installation center and the reference distance is the adjustment distance mark 430 of the corresponding adjustment part 410, such as 2 mm, 3 mm, etc. The adjustment distance mark 430 corresponds to the adjustment part 410 one by one.

[0123] refer to Fig.10 As shown, the adjustment component 400 has four adjustment parts 410, and the distance from the outer contour of each adjustment part 410 to the installation center of the main body 420 is different. The minimum distance is taken as the reference distance 0mm, and the adjustable distances of each adjustment part 410 can be 0mm, 0.2mm, 2.8mm, and 3.0mm in sequence. 0mm and 3.0mm are relatively set. Of course, other adjustment precisions can be freely selected, such as 0mm, 0.1mm, 0.15mm, and 0.2mm. The adjustment parts 410 that are relatively set in the same direction have the same adjustable distances added together, so that each adjustment component 400 has the same matching clearance with the slideway in the limit part in the left and right directions, which can minimize the spacing of the slideway in the left and right directions.

[0124] It can be understood that the main body 420 and the adjusting portion 410 are integrally formed, the adjusting component 400 has good integrity and structural stability, and the number of parts can be reduced.

[0125] In some cases, the main body 420 and the adjustment part 410 are detachably connected. Without removing the main body 420 from the cabinet panel 500, the adjustment part 410 can be detached from the main body 420 to switch the adjustment part 410 supported by the support limit part 300 to adjust the adjustment range in the height direction. If the main body 420 and the cabinet panel 500 are connected by threads, the problem of thread slippage caused by frequent removal of the main body 420 from the cabinet panel 500 can be solved. Among them, the main body 420 and the adjustment part 410 are detachably connected, which can be understood as the main body 420 and at least one adjustment part 410 are detachably connected. The main body 420 and the adjustment part 410 can be detachably connected by means of snap connection, hanging connection, thread connection, etc. The disassembly and assembly methods of the main body 420 and the adjustment part 410 are various and can be selected according to needs.

[0126] Understandably, reference Figures 10 to 14As shown, multiple adjustment parts 410 are integrally formed, the adjustment parts 410 and the support limit part 300 support each other, the outer end faces of the adjustment parts 410 and the support limit part 300 support each other, the outer end faces of adjacent adjustment parts 410 are connected by arcuate faces, and the outer end faces of the adjustment parts 410 are in an arcuate transition, which can avoid accidental injury to operators during the disassembly and assembly process, save materials, and reduce processing costs. Of course, if each adjustment part 410 is an independent part, the outer end faces of adjacent adjustment parts 410 can also be transitioned by an arcuate face.

[0127] In some cases, reference Fig.12 As shown, the outer end faces of the multiple adjustment parts 410 are connected end to end, and the multiple outer end faces are connected in sequence to form a closed-loop outer contour surface. The outer contour surface of the adjustment part 410 has a larger area and better supporting stability.

[0128] It is understandable that the main body 420 of the adjustment component 400 is provided with a mounting position, and the adjustment component 400 is connected to the cabinet board 500 through the mounting position, and the structural form of the mounting position is not limited. The mounting position can be a mounting hole 421, and the adjustment component 400 is connected to the cabinet board 500 through a first fastener 440 that penetrates the mounting hole 421. The mounting position can also be a first clamping portion, and the adjustment component 400 is clamped and fixed to each other with a second clamping portion of the cabinet board 500 through the first clamping portion.

[0129] refer to Fig.10 As shown, taking the mounting position as the mounting hole 421 as an example, the main body 420 can be provided with one or more mounting holes 421; when one mounting hole 421 is provided, the center of the mounting hole 421 can be provided at the mounting center or at the periphery of the mounting center; when the center of the mounting hole 421 is provided at the mounting center, it is fixed to the target position of the cabinet board 500 by a first fastener 440 penetrating the mounting hole 421, and by loosening the first fastener 440, the adjustment part 410 supported by the support limit part 300 can be rotatably switched, based on the outer periphery of the adjustment part 410 The end face and the support limit part 300 support each other, and only one mounting hole 421 is set to accurately switch the adjustment part 410; when a mounting hole 421 is set on the periphery of the installation center, the cabinet panel 500 needs to be equipped with multiple matching holes, and the number of matching holes is the same as the number of the adjustment part 410. By adjusting the position of the adjustment component 400, the mounting hole 421 is switched to the corresponding matching hole through the first fastener 440 to switch the adjustment part 410 supported by the support limit part 300, the structure of the adjustment component 400 can be simplified.

[0130] When multiple mounting holes 421 are provided, the multiple mounting holes 421 are centrally symmetrically distributed around the mounting center. At this time, one mounting hole 421 may be provided at the mounting center, or no mounting hole 421 may be provided at the mounting center, and one or more matching holes may be provided on the cabinet plate 500. When multiple mounting holes 421 are provided and the cabinet plate 500 is provided with one matching hole, the number of mounting holes 421 is the same as the number of adjustment parts 410. By adjusting the position of the adjustment part 400, the mounting hole 421 fastened to the matching hole is switched to switch the adjustment part 410 supported by the support limit part 300; when multiple mounting holes 421 are provided and the cabinet plate 500 is provided with multiple matching holes, the number of mounting holes 421 and the matching holes may be the same or different.

[0131] refer to Fig.13 As shown, the mounting hole 421 is configured as a countersunk hole, and the adjusting component 400 is physically connected to the cabinet panel 500 by means of a countersunk screw passing through the countersunk hole. The countersunk screw will not protrude from the plane of the adjusting component 400. The use of the countersunk screw can prevent the adjusting component 400 from scratching the supporting limit portion 300 or the device body 200 when moving, and the supporting limit portion 300 or the device body 200 does not need to be thickened to avoid the countersunk screw; the mounting hole 421 can be configured as a conical hole, and can also be configured as a step hole, so that the thickness of the rubber material of the through hole is increased, thereby increasing the force strength of the adjusting component 400.

[0132] refer to Fig.10 and Fig.11 As shown, the adjusting component 400 is provided with four adjusting parts 410, and the main body 420 is provided with four mounting holes 421, and the four mounting holes 421 are evenly distributed around the periphery of the mounting center. That is, the main body 420 is provided with a plurality of mounting holes 421, and the number of mounting holes 421 is the same as the number of the adjusting parts 410.

[0133] Other functions of the opening and closing device are described below.
