Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a push-mounting structure and a range hood. Background Technology
[0002] To enhance the aesthetics of the range hood and facilitate cleaning, it features a decorative panel. During installation, the panel can be directly hung onto the hooks of the range hood bracket via mounting holes, making installation convenient. However, when using a conventional hook structure, the decorative panel must first be lifted upwards until the mounting holes are at the top of the hooks, then the panel is lowered onto the hooks. To ensure stable installation, the hooks need to be of a predetermined length, requiring the decorative panel to be lifted a predetermined height. If the space between the range hood and the wall / cabinet is limited, this can lead to interference, making installation impossible, or resulting in a large gap between the range hood and the wall / cabinet after installation, affecting aesthetics and making cleaning difficult.
[0003] Therefore, there is an urgent need for a flat-mounting structure and a range hood to solve the above problems. Utility Model Content
[0004] One objective of this utility model is to provide a flat-push installation structure that requires little space during assembly, avoids interference in the assembly position, eliminates assembly gaps after assembly, is aesthetically pleasing, and does not cause cleaning difficulties.
[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:
[0006] A push-mount structure is provided, comprising:
[0007] A hook assembly that can be mounted on a decorative panel, the hook assembly having a limiting space;
[0008] The snap-fit assembly includes a mounting box and a sliding limiting member. The mounting box can be mounted on a range hood bracket. The sliding limiting member is slidably disposed in a guide groove of the mounting box in a first direction. The sliding limiting member includes a limiting member and an elastic member. The limiting member has a limiting lug protruding in a second direction. The snap-fit assembly can extend into the mounting box in a third direction and press against the limiting lug to force the limiting lug to move the limiting member away from the first position. The elastic member is sleeved on the limiting member so that the limiting member always tends to return to the first position, so that the limiting lug can be inserted into the limiting space. The first direction, the second direction, and the third direction are all perpendicular to each other.
[0009] Optionally, the hook assembly has a first guide ramp, the normal of the first guide ramp and the abutment surface of the limiting lug forming an angle α1 with the third direction, α1 ≠ 90°; and / or,
[0010] The limiting lug has a second guide slope, and the normal of the second guide slope and the contact surface of the hook assembly forms an angle a2 with the third direction, where a2 ≠ 90°.
[0011] Optionally, the hook assembly includes a hook, the hook including a hook rod and a hook head, the projection of the hook head onto the decorative panel in the third direction covering the hook rod, so that the hook head and the decorative panel form the limiting space in the third direction.
[0012] Optionally, the mounting box is provided with guide protrusions, and two sets of guide protrusions are arranged opposite each other along the third direction to form the guide groove. The mounting box wall is provided with an outer guide groove, and the outer guide groove is connected to both ends of the guide groove along the first direction.
[0013] Optionally, the mounting box has a first limiting surface and a second limiting surface spaced apart in the first direction. The elastic member is sleeved on the limiting member. One end of the elastic member abuts against the first limiting surface, and the other end of the elastic member abuts against a first limiting boss on the limiting member. The first limiting boss can abut against the second limiting surface.
[0014] Optionally, the limiting member is provided with a second limiting boss, the second limiting boss being located on the side of the first limiting boss away from the elastic member in the first direction, and the guide protrusion being located between the second limiting boss and the first limiting boss.
[0015] Optionally, the end of the limiting member is provided with a spring mounting groove, a spring mounting post is provided in the spring mounting groove, and the elastic member is located in the spring mounting groove and sleeved on the spring mounting post.
[0016] Optionally, the push-mount structure further includes a disassembly rod. An outer guide groove is provided on the wall of the mounting box. The outer guide groove communicates with the guide groove in the first direction. The disassembly rod can pass through the outer guide groove to push the limiting member to move in the first direction, so that the limiting lug moves out of the limiting space.
[0017] Optionally, the mounting box includes a box body and a cover, the cover being disposed on the box body and abutting against the limiting member in the second direction, so that the limiting member can only slide in the guide groove along the first direction.
[0018] Another objective of this utility model is to provide a range hood that requires little space during assembly, avoids interference in the assembly position, has no assembly gaps after assembly, is aesthetically pleasing, and does not cause cleaning difficulties.
[0019] Based on the above concept, the technical solution adopted by this utility model is as follows:
[0020] A range hood is provided, including a decorative panel, a range hood bracket, and the aforementioned push-mount structure. The hook assembly is mounted on the decorative panel, and the buckle assembly is mounted on the range hood bracket. The hook assembly is movable along the third direction to allow the limiting lug to be inserted into the limiting space.
[0021] The beneficial effects of this utility model are as follows:
[0022] The proposed push-mount structure includes a hook assembly and a buckle assembly. The hook assembly can be mounted on a decorative panel and has a limiting space. The buckle assembly includes a mounting box and a sliding limiting member. The mounting box can be mounted on a range hood bracket, with its opening facing the hook assembly. The sliding limiting member is slidably positioned in a guide groove within the mounting box in a first direction. The sliding limiting member includes a limiting member with a protruding limiting lug in a second direction. The hook assembly can move upwards in a third direction to press against the limiting lug and force the limiting lug to move the limiting member away from its first position in the first direction. The sliding limiting member also includes an elastic member fitted onto the limiting member. The elastic member ensures that the limiting member always tends to return to its first position, allowing the limiting lug to insert into the limiting space, thereby securing the hook assembly and the buckle assembly.
[0023] When the decorative panel is moved along a third direction, the hook assembly also moves along that direction. When the hook assembly extends into the mounting box, it initially reaches a pressing position. In this position, the hook assembly presses against the side of the limiting lug away from the elastic element, pushing the limiting lug towards the elastic element and compressing it. At this point, the limiting element moves away from the first position along the first direction. As the hook assembly continues to move along the third direction, it moves away from the pressing position. No longer pressing against the side of the limiting lug away from the elastic element, the elastic force of the elastic element pushes the limiting element back to the first position. If the limiting lug is on the same plane as the limiting space in the first direction, it can be inserted into the limiting space. Throughout this process, the hook assembly only moves in the third direction, meaning the decorative panel can always move horizontally, without requiring the decorative panel to be lifted and then hung on the range hood bracket as in existing hanging methods. This push-mount structure is applied to decorative panels and range hood brackets, minimizing the space required for assembly, avoiding interference in assembly positions, eliminating gaps after assembly, resulting in an aesthetically pleasing appearance and eliminating cleaning difficulties. Furthermore, the varying degrees of compression of the elastic element by the limiting component allow for different relative positions of the decorative panel and range hood bracket in the first direction, accommodating processing and assembly errors between components.
[0024] The range hood proposed in this utility model includes a decorative panel, a range hood bracket, and the aforementioned push-mount structure. A hook assembly is installed on the decorative panel, and a latch assembly is installed on the range hood bracket. The hook assembly is movable along a third direction to allow the limiting lug to insert into the limiting space. This push-mount structure, applied to the decorative panel and range hood bracket, minimizes the space required for assembly, avoids interference in the assembly position, eliminates assembly gaps after assembly, and is aesthetically pleasing and easy to clean. Furthermore, the different degrees of compression of the elastic element by the limiting component allow for different relative positions of the decorative panel and range hood bracket in the first direction, accommodating processing and assembly errors between components.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0041] like Figures 1 to 7 As shown, this embodiment provides a push-mount structure, including a hook assembly 1 and a latch assembly 2. The hook assembly 1 can be disposed on the decorative panel 100 and has a limiting space 110. The latch assembly 2 includes a mounting box 21 and a sliding limiting member 22. The mounting box 21 can be disposed on the range hood bracket 200, and the opening of the mounting box 21 faces the hook assembly 1. The sliding limiting member 22 is slidably disposed in the guide groove 2110 of the mounting box 21 in a first direction. The sliding limiting member 22 includes a limiting member 222, and the limiting member 222 protrudes in a limiting lug 223 in a second direction. The hook assembly 1 can move upward in a third direction to press against the limiting lug 223, and can force the limiting lug 223 to drive the limiting member 222 to move away from the first position in the first direction. The sliding limit member 22 also includes an elastic member 221, which is sleeved on the limit member 222. The elastic member 221 is used to make the limit member 222 always tend to return to the first position so that the limiting lug 223 can be inserted into the limiting space 110, thereby fixing the hook assembly 1 and the buckle assembly 2.
[0042] In this embodiment, Figure 7The first, second, and third directions shown are mutually perpendicular. When the decorative panel 100 is moved along the third direction, the hook assembly 1 also moves along the third direction. When the hook assembly 1 is inserted into the mounting box 21, it will initially be in the pressing position. In this position, the hook assembly 1 presses against the side of the limiting lug 223 away from the elastic member 221. The hook assembly 1 pushes the limiting lug 223 toward the elastic member 221, thus compressing the elastic member 221. At this time, the limiting member 222 moves away from the first position along the first direction. As the hook assembly 1 continues to move along the third direction, it will move away from the pressing position. The hook assembly 1, now away from the pressing position, no longer presses against the side of the limiting lug 223 away from the elastic member 221. At this time, the elastic force of the elastic member 221 will push the limiting member 222 to move in the first direction to return to the first position. If the limiting lug 223 is on the same plane as the limiting space 110 in the first direction, the limiting lug 223 can be inserted into the limiting space 110. During this process, the hook assembly 1 only moves upward in the third direction, that is, the decorative panel 100 can always move horizontally, without the need for the hanging method in the prior art, which requires first lifting the decorative panel 100 upward and then hanging it on the range hood bracket 200 downward. This push-mounting structure can be applied to the decorative panel 100 and the range hood bracket 200, so that the space required for the assembly of the decorative panel 100 and the range hood bracket 200 is small, which can avoid interference in the assembly position, and there will be no assembly gap after assembly, which is aesthetically pleasing and does not cause cleaning difficulties. In addition, the different degrees of compression of the elastic member 221 by the limiting member 222 can also make the relative position of the decorative panel 100 and the range hood bracket 200 different in the first direction, which can accommodate the processing errors and assembly errors between the components.
[0043] In order to enable the hook assembly 1 to press against the limiting lug 223 in the third direction and enable the limiting lug 223 to move in the first direction, in addition to setting the guide groove 2110 to guide the movement direction of the limiting member 222, the force direction at the contact point between the hook assembly 1 and the limiting lug 223 is not parallel to the third direction.
[0044] Specifically, such as Figure 1As shown, the hook assembly 1 has a first guide slope 1121, which abuts against the limiting lug 223. The normal of the abutment surface of the first guide slope 1121 and the limiting lug 223 forms an angle α1 with a third direction, where α1 ≠ 90°. Due to the inclined arrangement of the first guide slope 1121, even if the hook assembly 1 moves in the third direction, the external force exerted by the hook assembly 1 on the limiting lug 223 also forms an angle with the third direction, giving the limiting lug 223 a tendency to move along the guide groove 2110. Alternatively, the limiting lug 223 may have a second guide slope, in which case the normal of the abutment surface of the second guide slope and the hook assembly 1 forms an angle α2 with a third direction, where α2 ≠ 90°. Similarly, the direction of the interaction force between the hook assembly 1 and the limiting lug 223 forms an angle with the third direction, thereby giving the limiting lug 223 a tendency to move along the guide groove 2110.
[0045] In addition, in specific implementation, such as Figure 7 As shown, the elastic element 221 is sleeved on the limiting element 222 so that the limiting element 222 tends to move to the left in the first direction. A first right guide slope is provided on the right side of the central axis of the hook assembly 1. The limiting lug 223 abuts against the first right guide slope. When the hook assembly 1 moves upward in the third direction, the first right guide slope can push the limiting lug 223 to move to the right in the first direction until the limiting lug 223 moves to the right side of the first right guide slope, loses the pressure of the first right guide slope on the limiting lug 223, and is limited by the pushing of the elastic element 221 on the limiting element 222 to the left in the first direction, so that the limiting lug 223 is pushed into the limiting space 110 on the right side of the hook assembly 1, so that the hook assembly 1 and the buckle assembly 2 are fixed.
[0046] In other embodiments, the elastic member 221 is sleeved on the limiting member 222 so that the limiting member 222 tends to move to the right in the first direction. Then, a first left guide slope is provided on the left side of the central axis of the hook assembly 1. The limiting lug 223 abuts against the first left guide slope. When the hook assembly 1 moves upward in the third direction, the first left guide slope can push the limiting lug 223 to move to the left in the first direction until the limiting lug 223 moves to the left side of the first left guide slope, loses the pressure of the first left guide slope on the limiting lug 223, and is limited by the pushing of the elastic member 221 on the limiting member 222 to the left in the first direction. This allows the limiting lug 223 to be pushed into the limiting space 110 on the left side of the hook assembly 1, so that the hook assembly 1 and the buckle assembly 2 are fixed.
[0047] In this embodiment, the hook assembly 1 is symmetrically provided with a first left guide slope and a first right guide slope, and two limiting spaces 110 are symmetrically provided on the left and right sides of the hook assembly 1, so that the limiting member 222 and the elastic member 221 can be assembled in the guide groove 2110 as needed, and the elastic member 221 can make the limiting member 222 have a tendency to move to the left or to the right in the first direction.
[0048] In this embodiment, the hook assembly 1 includes a hook 11, which includes a hook rod 111 and a hook head 112. The projection of the hook head 112 onto the decorative panel 100 in a third direction covers the hook rod 111, so that the hook head 112 and the decorative panel 100 form a limiting space 110 in the third direction. In short, the limiting space 110 is formed by the inwardly recessed portion of the hook rod 111 in the first direction. In other embodiments, the hook rod 111 and the hook head 112 may not be distinguished; a first guide slope 1121 may be provided on the hook 11 to abut against the limiting lug 223, while a recessed groove in the first direction may be provided where the first guide slope 1121 is not provided. During assembly, the hook assembly 1 may also include a fixing member 12, with the hook 11 disposed on the fixing member 12, and then the fixing member 12 installed on the decorative panel 100. Alternatively, the hook 11 may be directly installed on the decorative panel 100.
[0049] Optionally, such as Figure 4 As shown, the mounting box 21 is provided with guide protrusions 2111. Two sets of guide protrusions 2111 are arranged opposite each other in a third direction to form guide grooves 2110. An outer guide groove 2110 is provided on the box wall of the mounting box 21, and the outer guide groove 2110 is connected to both ends of the guide groove 2110 in a first direction. That is, in this embodiment, the guide groove 2110 is the area between the two sets of guide protrusions 2111 in the mounting box 21, and the two ends of the guide groove 2110 are connected, which makes it convenient for the user to apply a force in the first direction to the limiting member 222 outside the mounting box 21, so that the limiting lug 223 disengages from the limiting space 110, thereby releasing the fixation of the hook assembly 1 and the buckle assembly 2.
[0050] Optionally, such as Figure 3 As shown, the push-mount structure also includes a disassembly rod 224. The disassembly rod 224 can pass through the outer guide groove 2112 to push the limiting member 222 to move in the first direction, so that the limiting lug 223 moves out of the limiting space 110. In this embodiment, the end of the limiting member 222 that engages with the disassembly rod 224 is provided with a disassembly hole. The disassembly rod 224 can be inserted into the disassembly hole to push the limiting member 222 to move in the first direction, preventing the disassembly rod 224 from sliding relative to the limiting member 222 during use.
[0051] Furthermore, the mounting box 21 has a first limiting surface and a second limiting surface spaced apart in a first direction. An elastic member 221 is sleeved on the limiting member 222. One end of the elastic member 221 abuts against the first limiting surface, and the other end abuts against the first limiting boss 2222 on the limiting member 222. The first limiting boss 2222 can abut against the second limiting surface. The elastic member 221 is located between the first limiting surface and the first limiting boss 2222. When the hook 11 presses against the limiting lug 223 to move the limiting member 222 towards the first limiting surface in the first direction, the elastic member 221 is compressed. When the hook 11 no longer presses against the limiting lug 223, the elastic member 221 allows the limiting member 222 to move towards the second limiting surface in the first direction, thereby causing the first limiting boss 2222 to abut against the second limiting surface, thus preventing the sliding limiting member 22 from disengaging from the guide groove 2110 in the first direction.
[0052] Furthermore, such as Figure 6 As shown, the limiting member 222 is further provided with a second limiting boss 2223. The second limiting boss 2223 is located in the first direction on the side of the first limiting boss 2222 away from the elastic member 221, and the guide protrusion 2111 is located between the second limiting boss 2223 and the first limiting boss 2222. In this embodiment, refer to... Figure 7 When the limiting member 222 moves to the right in the first direction to compress the elastic member 221, the second limiting boss 2223 abuts against the left side of the guide protrusion 2111. When the elastic member 221 pushes the limiting member 222 to the left in the first direction so that the limiting lug 223 is inserted into the limiting space 110, the first limiting boss 2222 abuts against the right side of the guide protrusion 2111. The cooperation between the guide protrusion 2111 and the first limiting boss 2222 and the second limiting boss 2223 can limit the movement distance of the limiting member 222 in the first direction, so as to prevent the limiting member 222 from exceeding the preset range when moving, and ensure the precise positioning of the hook assembly 1 and the buckle assembly 2 each time.
[0053] Optionally, a spring mounting groove 2220 is provided at the end of the limiting member 222, and a spring mounting post 2221 is provided within the spring mounting groove 2220. The elastic member 221 is located within the spring mounting groove 2220 and sleeved on the spring mounting post 2221. The spring mounting groove 2220 can prevent the elastic member 221 from being subjected to forces other than those in the first direction, thus ensuring the pushing function of the elastic member 221 on the limiting member 222.
[0054] In this embodiment, as Figures 3 to 5As shown, the mounting box 21 includes a box body 211 and a cover 212. The cover 212 covers the box body 211 and abuts against the limiting member 222 in the second direction, so that the limiting member 222 can only slide in the guide groove 2110 in the first direction. By detachably connecting the box body 211 and the cover 212, it is not only convenient to assemble the limiting member 222 from top to bottom in the guide groove 2110, but also to limit the guide groove 2110 in the second direction. In this embodiment, a limiting post 2121 is provided on the side of the cover 212 facing the box body 211. The limiting post 2121 is inserted into the outer guide groove 2112 and can abut against the limiting member 222. The limiting post 2121 and the guide protrusion 2111 cooperate to restrict the limiting member 222 to move only in the guide groove 2110 in the first direction, so as to prevent the limiting member 222 from disengaging from the guide groove 2110 when subjected to a force other than the first direction.
[0055] This embodiment also provides a range hood, including a decorative panel 100, a range hood bracket 200, and the aforementioned push-mount structure. A hook assembly 1 is mounted on the decorative panel 100, and a latch assembly 2 is mounted on the range hood bracket 200. The hook assembly 1 can move along a third direction to allow the limiting lug 223 to insert into the limiting space 110. During this process, the decorative panel 100 can always move horizontally, eliminating the need for the hanging method in the prior art, which requires first lifting the decorative panel 100 upwards and then hanging it downwards onto the range hood bracket 200. This push-mount structure, applied to the decorative panel 100 and the range hood bracket 200, minimizes the space required for assembly, avoids interference in the assembly position, eliminates assembly gaps after assembly, and is aesthetically pleasing without causing cleaning difficulties. Furthermore, the varying degrees of compression of the elastic member 221 by the limiting member 222 can also result in different relative positions of the decorative panel 100 and the range hood bracket 200 in the first direction, accommodating processing and assembly errors between components.
[0056] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
