Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a bearing fixing frame and a seat crane. Background Art

[0002] The volute fixing plate is an important part of the bearing support frame of the crane. Since the crane can be mounted on the base or hoisted, the stability of the volute fixing plate affects the reliability of the unit, as well as the noise and air volume of the unit. The current crane generally uses a support rod to connect the upper end of the volute fixing plate and the lower part of the chassis by screwing or clamping.

[0003] The applicant conducted research on air conditioners in the early stage and submitted a patent application with application number: 201821217859.8, which disclosed a seat crane, including a volute fixing plate, a chassis and a connecting rod, wherein the connecting rod is arranged between the volute fixing plate and the chassis, and fixedly connects the volute fixing plate and the chassis, and the connecting rod is engaged and fixed with at least one of the volute fixing plate and the chassis. However, the above structure still needs to be improved in terms of positioning by naked eyes during assembly, low assembly efficiency, unreasonable support rod structure, and poor space utilization.

[0004] With the further research of the applicant, it is very necessary to design a bearing support frame with simple structure, easy disassembly and assembly and high space utilization. Summary of the invention

[0005] The problem solved by the invention is to optimize the structure of the bearing fixing frame and improve the disassembly and assembly efficiency and space utilization.

[0006] In order to solve the above problems, the present invention provides a bearing fixing frame, including a bearing bracket and a volute fixing plate and a chassis connected thereto, wherein the bearing bracket includes a plate body and a first folding edge and a second folding edge arranged at both ends thereof, wherein the bearing bracket is connected to the volute fixing plate through a first assembly structure, and wherein the bearing bracket is connected to the chassis through a second assembly structure. On the one hand, this arrangement enables the bearing bracket to be quickly positioned between the volute fixing plate and the chassis, thereby improving the convenience of assembly; on the other hand, sufficient space is formed between the bearing bracket, the chassis and the volute fixing plate to accommodate the extended shaft and the volute assembly, thereby making the structure of the bearing fixing frame more reasonable and having a high space utilization rate.

[0007] Furthermore, the first folded edge is vertically arranged on one side of the plane where the plate body is located, and the second folded edge is vertically arranged on the other side of the plane where the plate body is located. This arrangement, on the one hand, allows the first folded edge and the second folded edge to fit the volute fixing plate and the chassis respectively, thereby increasing the force-bearing area; on the other hand, the bearing bracket can be further arranged to be centrally symmetrical with the central axis of the plate body located on the plane where the plate body is located, so that the connection between the bearing bracket and the chassis or the volute fixing plate is not restricted by the orientation of the first folded edge and the second folded edge, and the disassembly and assembly are more convenient.

[0008] Furthermore, the plate body is bent in an arc shape along the plane where the plate body is located, and the angle formed by the plane where the first folded edge and the second folded edge are located is α, and 70°≤α≤110°; the angle formed between the volute fixing plate and the chassis is β, and 70°≤β≤110°. Preferably, α=β=90°. This setting can increase the space between the bearing bracket and the volute fixing plate and the chassis, facilitate the installation of components such as the extension shaft and the volute assembly, and improve space utilization.

[0009] Furthermore, the first assembly structure includes a first assembly hole located on the first folded edge and a first fixing hole located at a corresponding position of the volute fixing plate, and the first assembly hole and the first fixing hole are fixed by screw connection. This arrangement can realize the assembly of the first folded edge and the volute fixing plate by one screw, and is easy to produce and process.

[0010] Furthermore, the first assembly structure further includes at least one first positioning hole located on the first folded edge and at least one positioning convex bump located at a corresponding position of the volute fixing plate, and the first positioning hole and the positioning convex bump can cooperate for positioning. This arrangement can realize the rapid positioning of the first folded edge and the volute fixing plate in the vertical direction.

[0011] Furthermore, the first positioning holes are two and symmetrically arranged on the left and right sides of the first assembly hole, and the first positioning holes are plugged and connected with the positioning convex bumps to cooperate with the positioning. This arrangement can further prevent the first folded edge from deflecting in the vertical direction, improve the accuracy of positioning; and at the same time make the appearance of the first assembly structure beautiful and convenient for production and processing.

[0012] Furthermore, the second assembly structure includes a second positioning hole located on the second folded edge and a positioning protrusion located at a corresponding position of the mounting boss, the mounting boss is arranged on the chassis, and the second positioning hole is plugged and fixed with the positioning protrusion. This arrangement can facilitate the positioning and assembly between the second folded edge and the chassis.

[0013] Furthermore, the second assembly structure further includes at least one second assembly hole located on the second folded edge and at least one second fixing hole provided at a corresponding position of the mounting boss, and the second assembly hole and the second fixing hole can be matched for positioning.

[0014] Furthermore, the second assembly holes are symmetrically arranged on the left and right sides of the second positioning hole, and the second assembly holes are screwed and fixed to the second fixing holes. This setting can be connected with two screws as needed, taking into account the tightness and convenience of assembly between the two.

[0015] Furthermore, the volute fixing plate is provided with a volute assembly, and there are two bearing brackets, which are respectively located on both sides of the volute assembly and are arranged symmetrically. This arrangement increases the mechanical strength of the bearing fixing bracket and makes it beautiful in appearance.

[0016] Compared with the prior art, the bearing support frame of the present invention has the following advantages:

[0017] (1) The present invention can realize the rapid positioning and assembly between the bearing bracket and the volute fixing frame and the chassis respectively, and at the same time, by providing a plurality of positioning holes / protrusion structures, the bearing bracket is prevented from being offset in the vertical direction, thereby further improving the positioning accuracy;

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1-Figure 4 As shown, a bearing fixing frame is used on a crane, including a bearing bracket 1 and a volute fixing plate 2 and a chassis 3 connected thereto, the volute fixing plate 2 being provided with an air outlet 23, a volute assembly 5 being provided on one side of the air outlet 23, one end of the bearing bracket 1 being connected to the side of the volute fixing plate 2 on which the volute assembly 5 is provided, and the other end of the bearing bracket 1 being connected to the upper surface of the chassis 3, and components such as an extension shaft 4 and an axial flow fan blade are provided in the space formed by the bearing bracket 1, the volute fixing plate 2 and the chassis 3. As an example of the present invention, there is at least one bearing bracket 1, and the number of bearing brackets 1 can be set as required, taking into account the stability and convenience of assembly. Preferably, there are two bearing brackets 1, which are respectively provided on both sides of the volute assembly 5, and are symmetrically arranged along the longitudinal axis of the volute assembly 5. This arrangement can increase the mechanical strength of the bearing fixing frame.

[0035] like Figure 7 , Figure 8As shown, the bearing bracket 1 includes a plate body 11 and a first folded edge 12 and a second folded edge 13 arranged at both ends thereof, a first assembly structure 14 is arranged between the first folded edge 12 and the volute fixing plate 2; a second assembly structure 15 is arranged between the second folded edge 13 and the chassis 3, the bearing bracket 1 is connected to the volute fixing plate 2 through the first assembly structure 14, and the bearing bracket 1 is connected to the chassis 3 through the second assembly structure 15. This setting can realize fast and accurate positioning between the bearing bracket 1 and the volute fixing plate 2 and the chassis 3, and improve the convenience of assembly. The first folded edge 12 and the second folded edge 13 can be located on the same side or different sides of the plate body 11. Preferably, the first folded edge 12 is vertically arranged on one side of the plane where the plate body 11 is located, and the second folded edge 13 is vertically arranged on the other side of the plane where the plate body 11 is located. On the one hand, this setting makes the first folded edge 12 and the second folded edge 13 fit the volute fixing plate 2 and the chassis 3 respectively, increasing the force bearing area. The plate body 11 is bent in an arc shape along the plane where the plate body 11 is located, so that sufficient space is formed in the bearing fixing frame to accommodate the extension shaft 4 and the volute assembly 5, etc., which makes the structure more reasonable and improves the space utilization. The angle formed by the plane where the first folded edge 12 and the second folded edge 13 are located is α, and 70°≤α≤110°; the angle formed between the volute fixing plate and the chassis is β, and 70°≤β≤110°.

As a preferred embodiment, Figure 3 As shown, α = β = 90°. This arrangement is convenient for arranging the extension shaft 4 and the volute assembly 5 and other components, and is also convenient for assembling other components.

[0036] As an example of the present invention, the first assembly structure 14 includes a first assembly hole 141 located on the first folded edge 12 and a first fixing hole 22 located at a corresponding position of the volute fixing plate 2, and the first fixing hole 22 can be a screw hole, and the first assembly hole 141 and the first fixing hole 22 are fixed by screw connection.

As another example of the present invention, the first assembly structure 14 also includes at least one group of first positioning holes 142 / positioning convex bulge 21 structures, and the first positioning holes 142 and the positioning convex bulge 21 can cooperate for positioning. This setting can be observed by naked eyes and / or the raised part can be touched by hand, so as to realize the rapid positioning of the first folded edge 12 and the volute fixing plate 2 in the vertical direction. The first positioning hole 142 is located on one of the first folded edge 12 or the volute fixing plate 2; the positioning convex bulge 21 is located on the other of the first folded edge 12 or the volute fixing plate 2. Preferably, the first positioning holes 142 are two and symmetrically arranged on the left and right sides of the first assembly hole 141, and the corresponding position of the volute fixing plate 2 is provided with a positioning convex bump 21, and the first positioning hole 142 is plugged and connected with the positioning convex bump 21.

Preferably, at least one reinforcing rib 16 is provided at the connection between the plate body 11 and the first folding edge 12 and the second folding edge 13. This arrangement can increase the connection strength between the first folded edge 12, the second folded edge 13 and the plate body 11, and improve the operating stability of the crane. As another example of the present invention, a notch 17 is provided on the plate body 11. This arrangement can reduce the weight of the bearing bracket 1 without reducing its mechanical strength, which is beneficial to the lightweight design of the crane. As an example of the present invention, the first folded edge 12 is provided with at least two connecting holes; one or two of the connecting holes can be replaced by positioning columns. During assembly, the first folded edge 12 can be connected to either the volute fixing plate 2 or the chassis 3, and the second folded edge 13 is connected to the other of the volute fixing plate 2 or the chassis 3, so as to improve assembly efficiency.
