Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to a volute support frame and a pedestal crane. Background Art

[0002] An air conditioner, that is, an air conditioner, its function is to adjust parameters such as the temperature, humidity, cleanliness, and air flow rate of the air in the room (or enclosed space, area) to meet the requirements of human comfort or technological processes. According to the installation method and installation position of the air conditioner, the air conditioner can be divided into different types. Among them, a pedestal crane is an air conditioner that can be installed in a pedestal-mounted manner or a hoisting manner.

[0003] In the prior art, the volute of the pedestal crane is usually long. In the pedestal-mounted state, there is a hidden danger of force-induced deformation, which in turn affects the operation stability and safety of the pedestal crane. Thus, it is very necessary to design a volute support frame according to the volute structure to meet the needs of the actual scenario. Summary of the Invention

[0004] The problem solved by the present invention is that in the prior art, the volute of the pedestal crane has a hidden danger of being easily deformed during the pedestal installation process.

[0005] To solve the above problems, the present invention provides a volute support frame provided on a pedestal crane. The pedestal crane includes a chassis, and a through hole is provided on the chassis. The volute support frame includes a volute fixing plate and at least one support member. One end of the support member is connected to the volute fixing plate, and a first flanging is provided at the other end of the support member. After passing through the through hole, the first flanging abuts against the chassis. This setting enables the first flanging of the support member to directly abut against the chassis, allowing the force to be directly transmitted to the chassis and increasing the force-bearing area. The structure of the volute fixing frame is simple and easy to assemble, which can prevent the situation that the volute is too long and easily deformed in the prior art, and enhance the overall strength of the pedestal crane in the pedestal-mounted environment.

[0006] Further, the support member includes a substrate. A chassis flange that slopes upward from bottom to top is formed on one side of the chassis facing the volute fixing plate. At least one second flanging is provided on the side edge of the substrate, and the second flanging abuts against the chassis flange at one end close to the first flanging. This setting can enhance the mechanical strength of the support member on the one hand, and on the other hand, through the contact between the second flanging and the chassis flange, it cooperates with the first flanging to play a secondary support role, improving the connection stability between the support member and the chassis.

[0007] Furthermore, the support member is located above the volute fixing plate and is perpendicular to the volute fixing plate. This setting can make the length of the support member shorter, reducing the production cost; at the same time, it makes the structure of the volute support frame compact and beautiful in appearance.

[0008] Further, the second flanging is located at the middle position of the substrate and is arranged along the long axis direction of the substrate, and the length of the second flanging is less than the length of the substrate. This setting makes the second flanging not fully extend to the end of the substrate, facilitating the assembly and fastening between the volute fixing frame and the chassis, while making its appearance beautiful and also facilitating machining.

[0009] Further, the first flanging is located on one of the upper or lower parts of the substrate, and the second flanging is located on the other of the upper or lower parts of the substrate. This setting enables the first flanging and the second flanging to support the chassis at different heights, making the force between the support member and the chassis more balanced.

[0010] Furthermore, ribs are provided on the substrate, and the ribs are located on the long axis of the substrate. This setting can further enhance the mechanical strength of the support plate and the volute fixing frame, and is also convenient for machining.

[0011] Further, a positioning hole is provided at one end of the support member connected to the volute fixing plate; an assembly hole is provided at a position corresponding to the positioning hole on the volute fixing plate, and the positioning hole and the assembly hole are fixed by screwing. The structure of this setting is simple, facilitating the assembly connection between the support member and the volute fixing plate and being convenient for disassembly and assembly; the positioning hole can also be replaced with structures such as snap fasteners.

[0012] Further, at least one reinforcing rib is provided at the connection between the first flanging and the substrate. This setting can increase the connection strength between the first flanging and the substrate, improve the structural stability of the support member and the operating stability of the seat crane.

[0013] Furthermore, the reinforcing rib is a stamped triangular rib. This setting is convenient for machining and has low production costs. Of course, the reinforcing rib can also be set in other shapes, such as strip-shaped and other shapes.

[0014] A seat crane includes the above-mentioned volute support frame. The seat crane has the same beneficial effects as the above-mentioned volute support frame. At the same time, by setting the volute support frame, it can also support the grille arranged parallel to the support member, preventing the grille from deforming or even breaking, thereby supporting multiple components, improving the overall strength and operating stability of the seat crane, and enhancing the product competitiveness.

[0015] Compared with the prior art, the volute fixing frame and the seat crane of the present invention have the following advantages:

[0016] (1) By setting the support member, the volute support frame of the present invention can effectively prevent the volute from being easily deformed due to its excessive length, and at the same time support the grille arranged parallel to the support member, thereby enhancing the overall strength of the seat crane in the seat-mounted environment;

[0017] (2) On the basis that the support member on the volute fixing frame of the present invention abuts against the chassis through the first flanging, it further abuts against the chassis through the second flanging, thereby realizing secondary support for the chassis, increasing the contact area between the support member and the chassis, and making the acting force between the two more balanced;

[0018] (3) The structure of the volute fixing frame of the present invention is simple, with low production cost and convenient assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] As Figures 1-4As described above, a volute fixing frame is provided on a pedestal crane. The pedestal crane includes a chassis 2 and a panel 4. The chassis 2 is provided with a chassis flange 22, and a through hole 21 is provided on the chassis flange 22. The volute fixing frame is arranged between the chassis 2 and the panel 4, and includes a volute fixing plate 3 connected to the panel 4 and at least one support member 1. One end of the support member 1 is connected to the volute fixing plate 3, and a first flange 12 is provided at the other end of the support member 1. After passing through the through hole 21, the first flange 12 abuts against the chassis 2. This setting enables the first flange 12 of the support member 1 to directly abut on the chassis 2, allowing the force to be directly transmitted to the chassis 2 and increasing the force-bearing area. As an example of the present invention, the support member 1 is vertically arranged on the upper part of the volute fixing plate 3, and the support member 1 is detachably connected to the volute fixing plate 3, such as by screwing or clamping. This setting can, on the one hand, make the length of the support member 1 shorter, reducing production costs; at the same time, it makes the support member 1 and the volute fixing plate 3 in the volute support frame easy to disassemble and assemble, improving the assembly efficiency. Preferably, there are three support members 1, which are arranged at equal intervals along the upper end of the volute fixing plate 3. As another example of the present invention, there are two support members 1, which are arranged symmetrically left and right along the longitudinal axis of the volute fixing plate 3. The support member 1 includes a substrate 11, and at least one second flange 13 is provided on the side edge of the substrate 11. The second flange 13 abuts against the chassis flange 22 at the end close to the first flange 12. This setting can, on the one hand, enhance the mechanical strength of the support member 1, and on the other hand, through the contact between the second flange 13 and the chassis flange 22, it cooperates with the first flange 12 to play a secondary support role, improving the connection stability between the volute fixing frame and the chassis 2. The structure of the volute fixing frame is simple and easy to assemble, which can prevent the volute from being too long and easily deformed in the prior art, and enhance the overall strength of the pedestal crane in the pedestal-mounted environment.

[0033] Embodiment 2

[0034] As Figure 5 、 6As shown in FIGS. 7 and 7, a support member 1 is provided between the volute fixing plate 3 and the chassis 2 of the seat crane. The chassis 2 is provided with through holes 21 having the same number as the support member 1. The support member 1 includes a substrate 11. One end of the substrate 11 is provided with a positioning hole 15, and the other end of the substrate 11 is provided with a first flanging 12. Preferably, the first flanging 12 is vertically provided at the end of the substrate 11, and the substrate 11 and the first flanging 12 together form an L-shaped structure. After the first flanging 12 passes through the through hole 21, it abuts against the chassis 2. This setting enables the first flanging 12 of the support member 1 to directly abut against the chassis 2, allowing the force to be directly transmitted to the chassis 2 and increasing the force-bearing area of the chassis 2. The structure of the support member 1 is simple and convenient for assembly, and can effectively fix and connect the chassis 2 and the volute fixing plate 3, prevent the chassis 2 from deforming under force, and enhance the overall strength of the seat crane in the seat-mounted environment. As an example of the present invention, the support member 1 can be a sheet metal part, can be integrally formed by injection molding, can also be formed by stamping and bending a sheet of material, or can be integrally formed by welding.

[0035] As an example of the present invention, at least one second flanging 13 is provided on the side edge of the substrate 11. Correspondingly, on the side of the chassis 2 facing the volute fixing plate 3, a chassis folding edge 22 that slopes upward from bottom to top is formed. One end of the second flanging 13 close to the first flanging 12 abuts against the chassis folding edge 22. This setting can enhance the mechanical strength of the support member 1 on the one hand, and on the other hand, through the contact between the second flanging 13 and the chassis 2, it jointly plays a secondary support role with the first flanging 12. Preferably, there are two second flangings 13 and they are symmetrically arranged along the long axis of the substrate 11. As a preferred example of the present invention, the end of the second flanging 13 close to the first flanging 12 is inclined, and its inclination angle is equal to that of the chassis folding edge 22. This setting makes the end of the second flanging 13 fit with the chassis folding edge 22 on the chassis 2, thereby increasing the contact area between the two. As an example of the present invention, the second flanging 13 is located at the middle position of the substrate 11 and is arranged along the long axis direction of the substrate 11, and the length of the second flanging 13 is less than the length of the substrate 11. This setting makes the second flanging 13 not fully extend to the end of the substrate 11, which is convenient for the positioning hole 15 at one end of the support member 1 to fit with the upper end surface of the volute fixing plate 3, making the assembly of the two firm, while making the appearance of the support member 1 beautiful and also facilitating machining. As an example of the present invention, the first flanging 12 is located on one side of the substrate 11, and the second flanging 13 is located on the other side of the substrate 11. For example, the first flanging 12 is located at the upper part of the substrate 11, and the second flanging 13 is located at the lower part of the substrate 11; or the first flanging 12 is located at the lower part of the substrate 11, and the second flanging 13 is located at the upper part of the substrate 11; this setting enables the first flanging 12 and the second flanging 13 to support the chassis 2 at different heights, making the force between the support member 1 and the chassis 2 more balanced. Preferably, the first flanging 12 is located at the upper part of the substrate 11, and the second flanging 13 is located at the lower part of the substrate 11.

[0036] During actual installation, after the positioning hole 15 is aligned with the assembly hole 31 on the volute fixing plate 3, it can be fixed by screws; this setting has the advantages of simple structure, convenient assembly connection between the support member 1 and the volute fixing plate 3, and easy disassembly and assembly. As another example of the present invention, the positioning hole 15 can be replaced with a buckle. Correspondingly, a card slot is provided on the volute fixing plate 3, and the assembly connection between the support member 1 and the volute fixing plate 3 is realized through the cooperation of the buckle and the card slot. As long as it is other deformation methods under the concept of the present invention, they are all within the protection scope of the present invention.

[0037] As an example of the present invention, at least one reinforcing rib 16 is provided at the connection between the first flanging 12 and the substrate 11. This setting can increase the connection strength between the first flanging 12 and the substrate 11, improve the structural stability of the support member 1 and the operating stability of the seat crane. Preferably, there are two reinforcing ribs 16, which are arranged symmetrically left and right along the longitudinal axis of the first flanging 12. This setting can effectively ensure the mechanical strength between the first flanging 12 and the substrate 11, and at the same time make the structure of the support member 1 simple and convenient for machining. As an example of the present invention, the reinforcing rib 16 is a stamping triangular rib. This setting is convenient for machining and has low production cost. Of course, the reinforcing rib 16 can also be set in other shapes, such as a long strip shape. As another example of the present invention, a rib 14 is provided on the substrate 11, and the rib 14 is located on the long axis of the substrate 11. This setting can further enhance the mechanical strength of the support member 1 and is convenient for machining.

[0038] Embodiment 3

[0039] As Figure 2 、 Figure 8 As shown, a support member 1 is arranged between the volute fixing plate 3 and the chassis 2 of the seat crane. The support member 1 includes a substrate 11, a first flanging 12, a second flanging 13, a rib 14, a positioning hole 15 and a reinforcing rib 16. By arranging the support member 1 on the seat crane, the connection strength between the chassis 2 and the volute fixing plate 3 can be enhanced, the volute can be prevented from deforming under force, and the overall strength of the seat crane in the seat-mounted environment can be enhanced. Preferably, the support member 1 is a sheet metal part, which is formed by stamping and bending a sheet of material. This setting can enhance the mechanical strength of the support member 1 and improve the service life. The substrate 11 is in a long strip shape, and the first flanging 12 is vertically arranged at the upper end of the substrate 11, and the two together form an L-shaped structure. Preferably, two reinforcing ribs 16 are provided at the connection between the first flanging 12 and the substrate 11 shown, and the reinforcing rib 16 is a stamping triangular rib. This setting can increase the connection strength between the first flanging 12 and the substrate 11, improve the structural stability of the support member 1 and the operating stability of the seat crane, and is convenient for production and processing at the same time.

[0040] The positioning hole 15 is provided at the other end of the substrate 11, that is, the positioning hole 15 and the first flanging 12 are respectively located at both ends of the substrate 11. The second flanging 13 is located at the middle position of the substrate 11 and is arranged along the long axis direction of the substrate 11, and the length of the second flanging 13 is less than the length of the substrate 11. This setting can enhance the mechanical strength of the support member 1 on the one hand; on the other hand, the second flanging 13 does not fully extend to the end of the substrate 11, which is convenient for the end parts of the support member 1 to be tightly assembled with the chassis 2 and the volute fixing plate 3 respectively. Preferably, there are two second flangings 13, both of which are located at the lower part of the side of the substrate 11, and the second flangings 13 are respectively located on both sides of the long axis of the substrate 11, showing a left-right symmetric arrangement; one end of the second flanging 13 close to the first flanging 12 is inclined, and its inclination angle is the same as that of the chassis flange 22. This setting can make the second flanging 13 fit with the chassis flange 22 during assembly, increase the force-bearing area of the two, and make the force more balanced. Preferably, there are ribs 14 on the substrate 11, and the ribs 14 are located on the long axis of the substrate 11. This setting can further enhance the mechanical strength of the support member 1 and is convenient for machining. As an example of the present invention, the ribs 14 are embedded in the substrate 11.

[0041] During assembly, after the first flanging 12 of the support member 1 passes through the through hole 21 on the chassis 2, the positioning hole 15 at the other end of the substrate 11 corresponds to the assembly hole 31 on the volute fixing plate 3, and the two are fixedly connected by inserting or screwing in screws; at this time, the other end of the substrate 11 abuts against the chassis 2, as Figure 9 shown. Specifically, the first flanging 12 fits with the inner side surface of the chassis 2. This setting can directly transfer the force to the chassis 2, increase the force-bearing area of the chassis 2, and make the force more balanced. At the same time, one end of the second flanging 13 close to the first flanging 12 abuts against the chassis flange 22 on the chassis 2, so as to realize the secondary support for the chassis 2. The structure of the support member 1 is simple, the production cost is low, and it is convenient for machining.

[0042] Embodiment 4

[0043] A seat crane includes components such as an air inlet grille, an axial flow fan blade, a panel 4, etc. Since its specific structure and assembly relationship are all prior arts, they will not be elaborated here.

One end of the support member 1 is fixedly connected to the volute fixing plate 3 by screwing, and the other end abuts against the chassis 2. The support member 1 is arranged in parallel inside the air inlet grille. Preferably, there are two support members 1, which are arranged symmetrically about the longitudinal axis of the seat crane.
