Description

Technical Field

[0001] This application relates to the field of component installation technology, and in particular to an elastic limiting mechanism, installation structure and air handling equipment. Background Technology

[0002] To facilitate the installation of components (such as filter screen assemblies), existing technologies typically use bolt connections or snap-fit ​​connections to fix the components. However, these installation and fixing methods require corresponding screw holes or snap-fit ​​structures to be set on the mounting frame. Once the size of the components changes, universal installation cannot be achieved.

[0003] For example, some products are designed with a filter installation slot reserved according to the maximum size. However, if the filter assembly used by the user is smaller, the filter assembly often cannot be fixed, and the airflow can easily leak from the connection gap outside the filter assembly, thus failing to play a purification role and causing the air handling equipment (such as residential units) to have unclean air output.

Furthermore, the connector and the fixing member have multiple connection positions along the axial direction of the connector, and the initial distance between the adsorption assembly and the fixing member can be adjusted by adjusting the connection position of the fixing member along the axial direction of the connector.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0053] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0054] To address the technical problem of poor versatility in component installation methods in existing technologies, this application provides an elastic limiting mechanism, an installation structure, and an air treatment device. The elastic limiting mechanism includes a relatively sliding connector 1 and an adsorption component 2. In the axial direction of the connector 1, the connector 1 and the fixing component 3 have multiple connection positions, giving the elastic limiting mechanism a certain axial adjustment space. This enables the limiting and fixing of components of various sizes, which is beneficial to improving the versatility of the installation structure.

[0055] Please see Figures 1 to 14 The first aspect of this application provides an elastic limiting mechanism, including a connector 1, an adsorption component 2, a fixing component 3, and an elastic component 4. The connector 1 has a first end and a second end; the adsorption component 2 is slidably connected to the first end, allowing the adsorption component 2 to slide along the axial direction of the connector 1; the fixing component 3 is detachably connected to the second end, and the fixing component 3 and the second end have multiple connection positions along the axial direction of the connector 1, allowing adjustment of the initial distance between the adsorption component 2 and the fixing component 3 by adjusting the connection positions of the fixing component 3 along the axial direction of the connector 1; the elastic component 4 always has a tendency to slide the adsorption component 2 away from the fixing component 3. When the second end of the connector 1 is fixed, the adsorption component 2 can adsorb and abut against the component to be installed, suitable for abutting and limiting components of different sizes, ensuring the installation stability of the component to be installed, such as... Figure 1 , Figure 6 and Figure 8 As shown.

[0056] In some embodiments of this application, please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 Using filter assembly 6 as the component to be installed, when the thickness of filter assembly 6 is small (denoted as H1), the adsorption component 2 abuts against the rear side of filter assembly 6. At this time, the compression degree of elastic element 4 is small, but the elastic force of elastic element 4 can still hold the adsorption component 2 firmly against the rear side of filter assembly 6, achieving stable installation of the filter assembly 6 with a small thickness. When the thickness of filter assembly 6 is large (denoted as H2), the compression degree of elastic element 4 is large. Elastic element 4 applies elastic force to adsorption component 2, holding it firmly against filter assembly 6, achieving stable installation of the filter assembly 6 with a large thickness. If it is difficult to install filter assemblies 6 of various sizes by simply changing the degree of expansion and contraction of elastic element 4, the axial connection position of fixing element 3 and connecting element 1 can be adjusted to adjust the initial distance between adsorption component 2 and fixing element 3, thereby adjusting the initial compression degree of elastic element 4.

[0057] It should be noted that this application can adjust the sliding distance of the adsorption assembly 2 relative to the first end of the connector 1 by adjusting the degree of expansion and contraction of the elastic member 4 and / or the axial connection position of the fixing member 3 and the connector 1, thereby adapting to the installation of parts of various sizes; the connection between the elastic limiting mechanism and the part to be installed can be made by adsorption connection through the adsorption assembly 2, and the adsorption connection method can be vacuum adsorption or magnetic adsorption, so that the elastic limiting mechanism of this application has the characteristics of high versatility and convenient disassembly and assembly.

[0058] In some embodiments of this application, please refer to Figure 7 and Figure 8 The first end of the connector 1 passes through the adsorption assembly 2. The first end of the connector 1 has a first limiting part 11, and the adsorption assembly 2 has a second limiting part 211. The first limiting part 11 and the second limiting part 211 are matched to prevent the first end from detaching from the adsorption assembly 2. When it is necessary to accommodate components of different sizes to be installed, the adsorption assembly 2 and the connector 1 can be flexibly adjusted by relative sliding. During this process, the first limiting part 11 and the second limiting part 211 can still cooperate tightly, always maintaining the limiting effect on the connector 1. No matter what position it slides to, the cooperation of the first limiting part 11 and the second limiting part 211 ensures that the connector 1 will not detach from the adsorption assembly 2, thereby ensuring the reliability of the elastic limiting mechanism throughout the entire size adjustment process.

[0059] In some embodiments of this application, please refer to Figure 3 and Figure 8 The first limiting part 11 is a disc disposed at the first end of the connector 1, and the diameter of the disc is larger than the diameter of the rod of the connector 1. The second limiting part 211 is a cylindrical limiting groove opened inside the adsorption assembly 2, which has both limiting function and axial sliding guiding function for the first limiting part 11.

[0060] It should be noted that the dimension of the second limiting part 211 in the axial direction of the connector 1 can be set according to the relative sliding stroke between the adsorption component 2 and the connector 1. As long as the first limiting part 11 of the connector 1 can be prevented from extending from both ends of the adsorption component 2, the purpose of this application can be achieved.

[0061] In the above embodiments, the fixing member 3 and the connecting member 1 can be connected by threaded connection, screw connection or snap connection to form multiple connection positions in the axial direction of the connecting member 1, all of which can realize the adjustment of the initial distance between the adsorption component 2 and the fixing member 3, thereby realizing the adjustment of the initial compression degree of the elastic member 4.

[0062] Please refer to some preferred embodiments of this application. Figure 1 , Figure 2 and Figure 3 The second end of the fixing part 3 is threadedly connected to the connecting part 1. By rotating the fixing part 3 or the connecting part 1, the distance can be precisely adjusted in the smallest unit of thread pitch. This allows for fine-tuning of the initial distance between the adsorption component 2 and the fixing part 3, thereby precisely controlling the initial compression degree of the elastic part 4. This can meet the application scenarios with strict requirements for elasticity.

[0063] Compared with screw connections and snap-fit ​​connections, threaded connections allow for continuous and precise distance adjustment, simplify the adjustment process, and improve the ease of use of the elastic limit mechanism.

[0064] In some embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 3 The second end of the connector 1 is provided with a stud section 12 for threaded connection with the fastener 3. The length of the stud section 12 can be designed according to the usage requirements and is not limited here.

[0065] In some embodiments of this application, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 8 The elastic element 4 is sleeved on the outside of the connector 1. The connector 1 can guide the elastic element 4 to extend and retract, so that the elastic element 4 always extends and retracts along the axial direction of the connector 1, thereby driving the adsorption assembly 2 to slide along the axial direction of the connector 1. The two ends of the elastic element 4 apply opposite thrusts to the adsorption assembly 2 and the fixing element 3, respectively, which can press the adsorption assembly 2 against the part to be installed, ensuring the installation stability of the part to be installed.

[0066] In the above embodiments, since the elastic element 4 has the ability to deform, when the elastic limiting mechanism is subjected to a large external force (such as impact, vibration, etc.), the elastic element 4 is also prone to expansion and contraction, which will cause the adsorption component 2 to shift and have an adverse effect on the fixation of the component to be installed.

[0067] To address the aforementioned issues, please refer to some embodiments of this application. Figure 1 , Figure 2 , Figure 4 , Figure 11 , Figure 12 and Figure 13 The adsorption component 2 includes a limiting member 21 and an adsorption member 22 connected together, which can move synchronously. The limiting member 21 is rotatably mounted on the connecting member 1. The limiting member 21 includes a first engaging part 212 for fixing its position. The limiting member 21 can switch between an engaging state and a sliding state by rotating. When the limiting member 21 is rotated to the engaging state, the first engaging part 212 engages with the external part, and the limiting member 21 cannot slide on the connecting member 1. When the limiting member 21 is rotated to the sliding state, the first engaging part 212 is disengaged from the external part, and the limiting member 21 can slide on the connecting member 1.

[0068] When the component to be installed needs to be stably installed, the limiting member 21 can be rotated to the position where it engages with the external part. At this time, the adsorption component 2 is limited by the external part, which can lock the adsorption component 2 and facilitate the installation of the component to be installed. After installation, when subjected to external force, it will not be displaced due to the expansion and contraction of the elastic member 4, which helps to ensure the installation stability of the component to be installed.

[0069] In some embodiments of this application, please refer to Figure 1, Figure 4 and Figure 8 The limiting member 21 also includes a sleeve portion 213, which is sleeved on the outside of the connecting member 1 for rotational connection with the connecting member 1. The two ends of the sleeve portion 213 are respectively connected to the elastic member 4 and the adsorption member 22, and can drive the adsorption member 22 to slide synchronously under the elastic force of the elastic member 4. The first locking portion 212 is fixedly connected to the sleeve portion 213 and can rotate synchronously with the sleeve portion 213, thereby realizing the switching between the locking state and the sliding state.

[0070] In some embodiments of this application, please refer to Figure 1 and Figure 4 The first locking part 212 extends in a direction perpendicular to the axis of the sleeve part 213, which makes it easy for the operator to push and pull the first locking part 212 to realize the rotation of the sleeve part 213 around the axis of the connector 1. The free end of the first locking part 212 is provided with a rough surface, which can increase the friction between the operator's hand and the first locking part 212, making it easier for the operator to push and pull the first locking part 212, and improving the convenience of the elastic limit mechanism to lock and unlock through the limit member 21.

[0071] It should be noted that the rough surface can be formed by setting anti-slip textures, uneven particles, or material coating (such as rubber). As long as it can improve grip and stability during operation and prevent slippage, the purpose of this application can be achieved.

[0072] Please refer to some preferred embodiments of this application. Figure 1 , Figure 2 , Figure 6 and Figure 8 The adsorption component 22 is a suction cup made of flexible material (such as rubber, silicone, etc.). It can not only adsorb non-magnetic materials to be installed, but also adapt to the size of the part to be installed and buffer the force through the deformation of the suction cup, so as to avoid hard contact between the adsorption component 2 and the part to be installed, and prevent the part to be installed from being damaged due to hard contact.

[0073] Please see Figures 1 to 14 The second aspect of this application provides an installation structure including the elastic limiting mechanism described in the above embodiments, and further including an installation base 5. The installation base 5 includes a first base 51 and a second base 52 disposed opposite to each other. A connector 1 is installed on the first base 51 and fixed by a fastener 3, which can prevent the connector 1 from moving relative to the first base 51, and at the same time provide a reaction force for the elastic limiting mechanism. The adsorption component 2 is disposed toward the second base 52 to form an adjustable installation space between the adsorption component 2 and the second base 52.

[0074] The component to be installed is positioned between the adsorption assembly 2 and the second base frame 52. The adsorption assembly 2 and the second base frame 52 can be used to press and limit the two sides of the component to be installed. Since the adsorption assembly 2 can slide along the axial direction of the connector 1, the distance between the adsorption assembly 2 and the second base frame 52 is adjustable, thereby making the size of the installation space adjustable, which can accommodate the installation and fixing of components of different sizes.

[0075] It should be noted that the distance between the first base frame 51 and the second base frame 52 can be set according to the largest size of the component to be installed, so that the largest component to be installed can also be installed in the mounting base frame 5. The elastic limiting mechanism can play a role in pressing and fixing the component to be installed, preventing the component to be installed from shaking between the first base frame 51 and the second base frame 52.

[0076] When the component to be installed is the filter assembly 6, the distance between the first base frame 51 and the second base frame 52 is greater than the maximum thickness dimension of the filter assembly 6 in this series, while leaving a certain margin to facilitate the installation of the elastic limiting mechanism.

[0077] In the above embodiments, the elastic limiting mechanism can directly abut against the surface of the component to be installed, thereby directly clamping the component to be installed. Alternatively, it can indirectly clamp the component to be installed by abutting against other components. As long as the side of the component to be installed away from the elastic limiting mechanism can be clamped against the second base frame 52, the purpose of this application can be achieved.

[0078] In some embodiments of this application, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The mounting base 5 also includes a third base 53, which is located between the first base 51 and the second base 52 and can be adjusted in position relative to the first base 51 and the second base 52. There are multiple elastic limiting mechanisms, and the adsorption components 2 of the multiple elastic limiting mechanisms are all connected to the third base 53. The third base 53 can move synchronously with the adsorption components 2 of the multiple elastic limiting mechanisms. The third base 53 is used to connect with the part to be installed and can evenly apply the elastic force applied by the multiple elastic limiting mechanisms to the part to be installed.

[0079] The third base frame 53, as an intermediate component, can rationally distribute and disperse the elastic forces applied by each elastic limiting mechanism, ensuring that the elastic forces on the component to be installed remain balanced in all directions. This uniform distribution of elastic forces not only effectively protects the component to be installed from damage caused by excessive local stress, but also improves the firmness and stability of the installation, ensuring that the component to be installed will not loosen or shift during long-term use.

[0080] It should be noted that the first base frame 51, the second base frame 52, and the third base frame 53 are arranged parallel to each other, and the elastic limiting mechanism is perpendicular to the first base frame 51, the second base frame 52, and the third base frame 53, respectively, so as to apply vertical force to the third base frame 53. The shapes of the first base frame 51, the second base frame 52, and the third base frame 53 can be set according to the structural characteristics and functions of the component to be installed. As long as the component to be installed can be fixed while avoiding affecting the function of the component itself, the purpose of this application can be achieved.

[0081] When the component to be installed is the filter assembly 6, since the filter assembly 6 needs to realize airflow and filter impurities, the arrangement of the first base frame 51, the second base frame 52 and the third base frame 53 should not obstruct the airflow. In this case, it is preferable to set the first base frame 51, the second base frame 52 and the third base frame 53 as a frame structure, beam structure or flange structure with hollow parts.

[0082] In some embodiments of this application, please refer to Figure 9 The first base frame 51 and the second base frame 52 are integrated. The second base frame 52 is a flanged structure located on both sides of the first base frame 51, allowing the second base frame 52 to abut and limit the sides of the filter screen. Both the first base frame 51 and the third base frame 53 have a perforated portion (not shown in the figure) in the middle that corresponds to the gas flow area of ​​the filter screen assembly 6, allowing airflow to... Figure 9 The airflow should be directed from bottom to top to avoid adverse effects of the first base frame 51 and the third base frame 53 on the airflow and filtration function of the filter assembly 6.

[0083] In some embodiments of this application, please refer to Figure 10 The edge of the third base frame 53 is provided with a bending portion 531, which can be used to limit the left and right sides and / or the top and bottom sides of the filter assembly 6 (to... Figure 10 The vertical direction in the image is the front-to-back direction, which can improve the installation accuracy of the filter assembly 6.

[0084] In some embodiments of this application, please refer to Figure 5 , Figure 6 , Figure 11 , Figure 12 and Figure 13 Multiple elastic limiting mechanisms are symmetrically arranged on both sides of the second base frame 52. The adsorption component 2 includes a limiting member 21, which is rotatably mounted on the connecting member 1. The limiting member 21 includes a first locking part 212 for fixing its position. The limiting member 21 can be rotated to switch between a locking state and a sliding state. When the limiting member 21 is rotated to the locking state, the limiting member 21 cannot slide on the connecting member 1. When the limiting member 21 is rotated to the sliding state, the limiting member 21 can slide on the connecting member 1.

[0085] The mounting base 5 also includes a first side plate 54 and a second side plate 55 arranged opposite to each other. Both the first side plate 54 and the second side plate 55 are provided with a second snap-fit ​​part 56 for engaging with the first snap-fit ​​part 212. When the component to be installed needs to be stably installed, the limiting member 21 can be rotated to the snap-fit ​​position of the first side plate 54 or the second side plate 55 on the corresponding side, so that the first snap-fit ​​part 212 and the second snap-fit ​​part 56 are snapped together. At this time, the adsorption component 2 is limited, which can lock the adsorption component 2. When subjected to external force, it will not be displaced due to the expansion and contraction of the elastic member 4, which helps to ensure the installation stability of the component to be installed.

[0086] In some embodiments of this application, the two ends of the first base frame 51 are perpendicularly connected to the first side plate 54 and the second side plate 55 respectively (the connection method can be screw connection or welding, etc.), and the elastic limiting mechanism is provided in the two side edge areas of the first base frame 51 so that the limiting member 21 of the elastic limiting mechanism can rotate and approach the first side plate 54 or the second side plate 55 to achieve engagement.

[0087] In some embodiments of this application, please refer to Figure 13 and Figure 14 The second engaging portion 56 includes a sliding groove 561 and an engaging slot 562. The extending direction of the sliding groove 561 is parallel to the sliding direction of the adsorption component 2. When the first engaging portion 212 is slidably disposed inside the sliding groove 561, the adsorption component 2 can slide along the axial direction of the connector 1 to adapt to the size of the component to be installed. The engaging slot 562 communicates with the sliding groove 561, and the extending direction of the engaging slot 562 is perpendicular to the extending direction of the sliding groove 561. This allows the first engaging portion 212 to vertically enter the engaging slot 562 from the sliding groove 561 when the limiting member 21 rotates around the axis of the connector 1. The engaging slot 562 then slides and limits the first engaging portion 212 and the adsorption component 2, thereby achieving the locking of the elastic limiting mechanism.

[0088] In some embodiments of this application, please refer to Figure 14 The number of locking slots 562 is multiple, and the multiple locking slots 562 are arranged sequentially along the length direction of the slide groove 561. Multiple locking positions can be formed in the axial direction of the elastic limiting mechanism, so that the elastic limiting mechanism can have a suitable locking position when tightening the parts to be installed of different sizes.

[0089] It should be noted that the shape of the second snap-fit ​​portion 56 can be L-shaped, F-shaped, or T-shaped, etc., as long as it can achieve the sliding guidance and locking function of the first snap-fit ​​portion 212, the purpose of this application can be achieved. The number and spacing of the snap-fit ​​slots 562 can be set according to the size differences of multiple components to be installed, and are not limited here.

[0090] Please see Figures 1 to 14 The third aspect of this application provides an air handling device, including the installation structure described in the above embodiments, and also includes a filter assembly 6. The filter assembly 6 is disposed inside the installation space, and an elastic limiting mechanism presses the filter assembly 6 against the second base frame 52, which can realize the stable installation of filter assemblies 6 of different sizes. The elastic limiting mechanism presses the filter assembly 6 against the second base frame 52 stably, ensuring the sealing between the filter assembly 6 and the internal airflow channel of the device, preventing unfiltered air from leaking into the room, thereby ensuring that all air entering the room is effectively purified by the filter, and ensuring the reliability of the filtration function of the filter assembly 6.

[0091] It should be noted that the air handling equipment can be an air purifier, air conditioner, or fresh air system, etc. The mounting base 5 is set at the air inlet of the air handling equipment, and the mounting base 5 can be configured as part of the equipment housing.

[0092] In some embodiments of this application, the air purification device is a residential unit, and the filter assembly 6 is a detachable module. It is clamped and limited by an elastic limiting mechanism, which can realize the stable installation of filter assemblies 6 of different sizes (such as thickness) inside the residential unit.

[0093] Please see Figures 1 to 14 In some embodiments of this application, the assembly process of the above-described mounting structure is as follows:

[0094] Step 1: Fix the third base frame 53 to the component to be installed (such as the filter assembly 6), pass the connecting piece 1 of the elastic limiting mechanism through the first base frame 51 and fix it with the fixing piece 3, so that the spring is in a pre-compressed state, and then push the first snap-fit ​​part 212 to make it in the snap-fit ​​locking position. At this time, the distance between the adsorption assembly 2 and the second base frame 52 is greater than the total size (such as the total thickness) of the third base frame 53 and the component to be installed.

[0095] Step 2: Insert the third base frame 53 and the component to be installed as a whole between the second base frame 52 and the adsorption component 2, so that the side of the component to be installed away from the adsorption component 2 is in close contact with the second base frame 52. At this time, there is a gap between the adsorption component 2 and the third base frame 53.

[0096] Step 3: Push the first engaging part 212 to switch the limiting member 21 to the sliding state. Under the elastic force of the elastic member 4, the adsorption component 2 presses against the third base frame 53 and the part to be installed. Push the first engaging part 212 again to engage it with the appropriate engaging groove 562, ensuring that the part to be installed is pressed against the groove while achieving locking.
