[0053] The embodiment of the utility model in the first aspect is to provide an adjustable hanging plate, as Figures 1 to 4 As shown, including fixed plate 1, moving plate 2 and elastic piece 3;

[0054] Fixed plate 1 is used to connect with installation surface 4;

[0055] Moving plate 2 penetrates fixed plate 1 and is slidably matched with fixed plate 1 along the vertical direction, and moving plate 2 is used to connect with the smoke machine body 5;

[0056] Elastic piece 3 is preset in fixed plate 1 and cooperates with moving plate 2, and elastic piece 3 is configured to allow moving plate 2 to slide upward relative to fixed plate 1 in the state of not being subjected to external force and allow moving plate 2 to slide upward and downward relative to fixed plate 1 under the action of external force.

[0057] Taking Figure 4 As an example, the use process of the above adjustable hanging plate is described in detail, elastic piece 3 is preset in fixed plate 1, fixed plate 1 is connected with the installation surface 4 of wall or cabinet, and moving plate 2 is connected with the smoke machine body 5.When the height of the smoke machine body 5 needs to be adjusted, the operator only needs to lift the smoke machine body 5, align moving plate 2 along the vertical direction to fixed plate 1, and push along the vertical direction upward, and when the height adjustment is completed, the smoke machine body 5 is released, and elastic piece 3 prevents moving plate 2 from sliding downward relative to fixed plate 1 along the vertical direction, realizing the locking of the height of moving plate 2, and then locking the height of the smoke machine body 5.When the locking state of moving plate 2 needs to be released, the operator only needs to apply external force to elastic piece 3, and elastic piece 3 allows moving plate 2 to slide upward and downward relative to fixed plate 1, realizing the disassembly of the smoke machine body 5.

[0058] The adjustable hanging plate can adjust the up-down position of the smoke machine body 5, has high adaptability, and the installation of the smoke machine body 5 is more beautiful, after adjustment, the height of the moving plate 2 is in a locking state, the position of the smoke machine body 5 is locked, and then the smoke machine body 5 is stably installed on the installation surface 4, and in the process of installing the moving plate 2 and the fixed plate 1, adjusting the height of the moving plate 2 and disassembling the moving plate 2, no additional tool is needed, and the disassembly difficulty and time cost are reduced.

[0059] In optional embodiments, as shown in Figure 5 and Figure 6 , the top end of the fixed plate 1 is provided with a first opening 11 and a second opening 12, and the second opening 12 is located on the side of the first opening 11 away from the installation surface 4.

[0060] In use, the moving plate 2 can be slidably connected with the fixed plate 1 through the first opening 11, and the elastic member 3 can be clamped in the fixed plate 1 through the second opening 12.

[0061] Specifically, before the moving plate 2 is slidably connected with the fixed plate 1 through the fixed plate 1, the part of the elastic member 3 located in the fixed plate 1 is clamped to the inner surface of the fixed plate 1; after the moving plate 2 is slidably connected with the fixed plate 1 through the fixed plate 1, the part of the elastic member 3 located in the fixed plate 1 is clamped between the inner surface of the fixed plate 1 and the moving plate 2.

[0062] In the above embodiments, the first opening 11 can pass through the top end of the moving plate 2, so as to facilitate the cooperation of the elastic member 3 and the moving plate 2 at a suitable position, limit the position of the moving plate 2 relative to the fixed plate 1, and prevent the top end of the fixed plate 1 from hindering the movement of the moving plate 2. The second opening 12 is provided to allow the elastic member 3 to pass through, so that the elastic member 3 is clamped in the fixed plate 1, the position of the elastic member 3 relative to the fixed plate 1 is preliminarily limited, the elastic member 3 is prevented from accidentally falling off in the unstressed state, and the elastic member 3 is directly pushed out when the moving plate 2 moves upward.

[0063] Specifically, the first opening 11 and the second opening 12 can be connected as shown in Figure 5 , and the first opening 11 and the second opening 12 can also be separately arranged.

[0064] In order to facilitate the elastic member 3 to extend into the fixed plate 1, the first opening 11 and the second opening 12 are connected, so that the elastic member 3 has a larger inlet area when extending into the fixed plate 1.

[0065] In addition, as shown in Figure 5 , the size of the first opening 11 and the second opening 12 in the width direction can be determined according to the width of the part of the moving plate 2 passing through the first opening 11 and the width of the part of the elastic member 3 passing through the second opening 12.

[0066] That is, the mobile plate 2 is used to pass through the part of the first opening 11, the width of which is larger, then the width size of the first opening 11 is larger, and vice versa; the elastic member 3 is used to pass through the part of the second opening 12, the width of which is larger, then the width size of the second opening 12 is larger, and vice versa. The above-mentioned arrangement can make the first opening 11 and the second opening 12 respectively adapt to the width of the mobile plate 2 and the elastic member 3, and limit the moving range of the mobile plate 2 and the elastic member 3 in the width direction to a certain extent.

[0067] In an optional embodiment, as shown in Figure 5 , the width of the first opening 11 is larger than the width of the second opening 12.

[0068] In an optional embodiment, as shown in Figures 6 to 8 , the fixed plate 1 includes a first limiting plate body 13 and a second limiting plate body 14, wherein: the first limiting plate body 13 can be connected with the mounting surface 4 through a connecting member such as a screw, the first limiting plate body 13 has a boss 131 protruding outward in the direction away from the mounting surface 4, both ends of the boss 131 in the vertical direction have an insertion hole 132 for the mobile plate 2 to pass through, the insertion hole 132 can cooperate with the first opening 11 to jointly limit the movement of the mobile plate 2 in the vertical direction relative to the fixed plate 1; the top end of the second limiting plate body 14 is connected with the top end of the first limiting plate body 13 and forms the first opening 11 and the second opening 12.

[0069] In the above-mentioned embodiment, both ends of the boss 131 in the vertical direction have the insertion hole 132 for the mobile plate 2 to pass through, which effectively limits the shaking of the mobile plate 2 in the width direction and the inclination of the mobile plate 2 in the front-back direction, so that the mobile plate 2 can be smoothly inserted into the fixed plate 1 and fixed in place, and the stability of the range hood body 5 is guaranteed.

[0070] In an optional embodiment, along the height direction of the first limiting plate body 13, the boss 131 can be located at the middle part of the first limiting plate body 13.

[0071] Specifically, before the mobile plate 2 penetrates through the fixed plate 1, the part of the elastic member 3 located in the fixed plate 1 is clamped between the first limiting plate body 13 and the second limiting plate body 14; after the mobile plate 2 penetrates through the fixed plate 1, the part of the elastic member 3 located in the fixed plate 1 is clamped between the mobile plate 2 and the second limiting plate body 14.

[0072] In the above-mentioned embodiment, before the mobile plate 2 penetrates through the fixed plate 1, the first limiting plate body 13 and the second limiting plate body 14 can abut against the elastic member 3, cooperate with the second opening 12 to limit the position of the elastic member 3 relative to the fixed plate 1, avoid the elastic member 3 from falling off the fixed plate 1 in the state of not being subjected to external force, and avoid the elastic member 3 from being pulled out of the fixed plate 1 upward when the mobile plate 2 moves upward relative to the fixed plate 1.

[0073] In optional embodiments, as shown in Figure 7 A plurality of third connecting holes 133 are formed in the first limiting plate body 13, and the third connecting holes 133 are used for connecting members such as screws to pass through to fix the first limiting plate body 13 to the mounting surface 4.

[0074] The third connecting holes 133 can be two, three, four, five or more, and in preferred embodiments, the third connecting holes 133 are four, and the four third connecting holes 133 are respectively distributed at the four corners of the first limiting plate body 13.

[0075] In optional embodiments, as shown in Figure 6 The second limiting plate body 14 gradually moves away from the first limiting plate body 13 along the direction from the top end to the bottom end.

[0076] The above embodiments can form an acute angle between the second limiting plate body 14 and the first limiting plate body 13, and more conveniently, the part of the elastic member 3 extending into the fixed plate 1 can abut against the inner wall of the second limiting plate body 14 and the first limiting plate body 13 before the moving plate 2 passes through the fixed plate 1.

[0077] In optional embodiments, as shown in Figure 7 The second limiting plate body 14 is provided with first connecting holes 141 for the connecting members 6 to pass through to lock the position of the elastic member 3 relative to the second limiting plate body 14.

[0078] When the moving plate 2 is moved to the position, the operator can pass the connecting members 6 through the first connecting holes 141 and connect with the elastic member 3 to lock the position of the elastic member 3 relative to the second limiting plate body 14, and effectively ensure that the elastic member 3 stably cooperates with the moving plate 2 to limit the downward movement of the moving plate 2, and further make the position of the range hood body 5 more stable.

[0079] On the basis of the above embodiments, as shown in Figure 8 The elastic member 3 is further provided with fourth connecting holes 311 arranged one by one with the first connecting holes 141, and the connecting members 6 can pass through the first connecting holes 141 and the fourth connecting holes 311 to lock the position of the elastic member 3 relative to the second limiting plate body 14.

[0080] The connecting members 6 can be but are not limited to screws, and the first connecting holes 141 can be through holes, and the fourth connecting holes 311 can be threaded holes.

[0081] The fixed plate 1 provided by the above embodiments is significantly different in thickness from the conventional bolted fixed plate 7, and in the average only about 11mm narrow space on the back of the range hood body 5, as shown in Figure 9As shown, the bolted fixing plate 7 is difficult to reduce in thickness due to the necessity of providing a through hole for bolt penetration on the top surface, which often causes spatial interference with the junction box or check valve of a specific machine model. In contrast, the fixing plate 1 provided by the above-mentioned embodiments is optimized in thickness, does not need to provide a through hole for bolt penetration on the top surface, and the second limiting plate body 14 is arranged obliquely, occupying less space in the direction perpendicular to the mounting surface 4, thereby avoiding such interference and exhibiting higher versatility and adaptability.

[0082] In optional embodiments, as shown in Figure 8 and Figure 10 , the elastic member 3 comprises a first limiting sheet 31 and a second limiting sheet 32 connected to the first limiting sheet 31; the first limiting sheet 31 is located in the fixing plate 1, and in the state of being clamped with the moving plate 2, the end of the first limiting sheet 31 close to the second limiting sheet 32 is used for clamping with the moving plate 2; the second limiting sheet 32 extends from the second opening 12 at the top end of the fixing plate 1.

[0083] The structure of the above-mentioned elastic member 3 is simple, the clamping of the first limiting sheet 31 with the moving plate 2 prevents the moving plate 2 from sliding downward relative to the fixing plate 1, realizes the fixation of the position of the moving plate 2, and cancels the clamping of the first limiting sheet 31 with the fixing plate 1 under the action of an external force through the elasticity of itself, which is convenient for the operation of the operator.

[0084] Specifically, as shown in Figure 10 , the end of the first limiting sheet 31 close to the second limiting sheet 32 has a limiting tooth 312 for clamping with the moving plate 2.

[0085] In optional embodiments, in the state of being clamped with the moving plate 2, the first limiting sheet 31 allows the moving plate 2 to slide upward relative to the fixing plate 1 in one direction, and the top of the first limiting sheet 31 close to the second limiting sheet 32 gradually moves away from the moving plate 2 in the direction from the top end to the bottom end of the first limiting sheet 31, and the second limiting sheet 32 gradually approaches the moving plate 2 in the direction from the top end to the bottom end of the second limiting sheet 32.

[0086] The above-mentioned embodiments can form an obtuse angle between the first limiting sheet 31 and the second limiting sheet 32, which facilitates the stable clamping of the first limiting sheet 31 in the fixing plate 1, and prevents the first limiting sheet 31 from falling off from the fixing plate 1 or being pulled out upward from the top end of the moving plate 2 when the moving plate 2 moves upward relative to the fixing plate 1.

[0087] As shown in Figures 12 to 13 , the first limiting sheet 31 allows the moving plate 2 to slide upward relative to the fixing plate 1 in one direction in the state of being clamped with the moving plate 2, as shown in Figure 14As shown, the second limiting piece 32, under the action of external force, causes the first limiting piece 31 to disengage from the moving plate 2. The first limiting piece 31 allows the moving plate 2 to slide up and down relative to the fixed plate 1. The following is combined with Figures 11 to 14 The usage process of elastic element 3 is explained in detail:

[0088] like Figure 11 As shown, in the initial state where the fixed plate 1 is not inserted with the movable plate 2, the limiting tooth 312 at the top of the first limiting piece 31 in the elastic member 3 abuts against the first limiting plate 13, the bottom end of the first limiting piece 31 abuts against the second limiting plate 14, and the second limiting piece 32 rests on the top of the second limiting plate 14, as shown. Figure 11 At the three black dots shown, the elastic element 3 and the fixed plate 1 can be considered to have three contact points, forming a stable limiting structure, thereby enabling the elastic element 3 to be stably locked inside the fixed plate 1.

[0089] like Figure 12 As shown, when the moving plate 2 begins to move upward, the first limiting piece 31 of the elastic member 3 gradually moves away from the moving plate 2 in the direction from its top end to its bottom end in the initial state. The first limiting piece 31 allows the moving plate 2 to pass upward. The thrust generated by the moving plate 2 causes the limiting teeth 312 to unfold outward so as to make room for the upward movement of the moving plate 2.

[0090] like Figure 13 As shown, after the height of the movable plate 2 is adjusted, the elastic element 3 naturally rebounds, and the limiting tooth 312 engages with the movable plate 2, thereby locking the height of the movable plate 2 and preventing it from sliding down. To further reinforce the position of the movable plate 2, the top of the movable plate 2 can be fixed to the mounting surface 4 using the connector 6. At the same time, the connector 6 can be used to lock the position of the first limiting piece 31 relative to the second limiting plate 14 by passing through the first connecting hole 141 and the fourth connecting hole 311.

[0091] like Figure 14 As shown, to release the above-mentioned locked state, the operator only needs to apply an appropriate upward force to the range hood body 5 and gently press down the second limiting piece 32. The second limiting piece 32 will drive the limiting tooth 312 away from the moving plate 2, canceling the engagement between the limiting tooth 312 and the moving plate 2, allowing the moving plate 2 to move freely in the vertical direction, which facilitates the disassembly operation of the range hood body 5.

[0092] In alternative implementations, such as Figures 11 to 14 As shown, the first limiting piece 31 is bent, and the elastic element 3 is in... Figure 11 In the state shown without external force, the angle between the top of the first limiting piece 31 and the mounting surface 4 is greater than the angle between the bottom of the first limiting piece 31 and the mounting surface 4, so as to facilitate the deformation of the first limiting piece 31 when the moving plate 2 is inserted into the fixed plate 1. Meanwhile, as Figure 12As shown, when the movable plate 2 is inserted into the fixed plate 1, the bent part of the first limiting piece 31 can abut against the second limiting plate 14, thereby limiting the position of the elastic element 3; as Figure 13 As shown, when the limiting tooth 312 at the top of the first limiting piece 31 engages with the moving plate 2, the above-mentioned arrangement facilitates the bottom of the first limiting piece 31 to be attached to the second limiting plate 14 and connected via the connector 6; Figure 14 As shown, when the operator presses down the second limiting piece 32, the above-mentioned arrangement facilitates the bottom of the first limiting piece 31 to abut against the moving plate 2 and limit the position of the elastic member 3.

[0093] In alternative implementations, such as Figure 15 As shown, the movable plate 2 includes a plug-in plate body 22, which penetrates the fixed plate 1 and has a plurality of spaced adjustment holes 221 along the vertical direction. The adjustment holes 221 are used to engage with the elastic member 3.

[0094] In actual operation, first connect one end of the plug plate 22 to the range hood body 5. Then, the user needs to lift the range hood body 5 so that the plug at the top of the plug plate 22 is aligned with the socket 132 of the fixing plate 1 and pushed upward. The plug plate 22 will then automatically push open the elastic element 3, completing the upward movement.
