Description

Technical Field

[0001] This utility model relates to the field of air conditioner installation accessories technology, and in particular to an air conditioner bracket that disperses the weight of the air conditioner and prevents damage to the profile connection through a dual-force-point connection structure. Background Technology

[0002] During air conditioner installation, the air conditioner bracket is the core component for securing the outdoor or indoor unit. Its connection strength directly affects the safety and lifespan of the air conditioner installation. In existing air conditioner bracket technology, the fixing and supporting profiles are typically connected using only a single bolt to form the stress point—that is, fixing is achieved by the bolt passing through corresponding holes in both.

[0003] However, air conditioners (especially floor-standing or high-power wall-mounted units) typically weigh tens to hundreds of kilograms. During long-term use, the weight of the air conditioner continuously acts on the supporting frame, causing significant stress concentration at the connection between the fixed and supporting frames. A single bolt bearing the entire weight must withstand the shear force and radial pressure, which can easily lead to the following problems: First, the bolt is prone to thread stripping, bolt deformation, or even breakage under long-term load; second, stress concentration at the frame connection edges can cause cracking and deformation, resulting in decreased connection strength; in severe cases, this can cause the supporting frame to tilt and the air conditioner to detach, posing a significant safety hazard. Furthermore, single-point connections require precise alignment of holes during installation, resulting in low assembly efficiency and failing to meet the dual requirements of stability and convenience in actual installation scenarios. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing air conditioner brackets are easily damaged due to single stress point connection, and to provide an air conditioner bracket with a dual stress point connection structure, which includes a fixed profile, a supporting profile and a supporting profile.

[0005] The fixing profile has several first mounting holes for fixing it to the wall or mounting surface. The fixing profile also has a hook and a positioning hole. The hook and the fixing profile are integrally formed to ensure the connection strength between the hook and the fixing profile.

[0006] The supporting profile has mounting holes for installing air conditioners. The supporting profile also has a hanging opening that matches the hook and a second positioning hole that matches the first positioning hole. The shape of the hanging opening matches the hook, making it easy for the two to be precisely engaged.

[0007] The supporting profile is fixedly connected to the fixed profile and the supporting profile by bolts. The fixed profile and the supporting profile are connected by two independent stress points: the first stress point is the snap-fit ​​between the hook and the hanging opening, and the second stress point is the threaded fit of the bolt through the positioning hole one and the positioning hole two.

[0008] The air conditioner bracket of this utility model disperses the weight of the air conditioner through the synergistic effect of two force points. Its detailed working principle is as follows: Load transfer start point: After the air conditioner is fixed to the support profile through the mounting holes on the support profile, the air conditioner's own weight will be transferred to the support profile, causing the support profile to generate a downward rotation torque with the fixed profile connection end as the fulcrum (that is, the free end of the support profile has a tendency to displace downward).

[0009] The function of the first stress point (hook-hanging-outlet snap-fit): Because the hook and hanging-outlet are tightly snapped together, when the supporting profile tends to rotate downwards, the hook will generate an upward supporting force on the upper edge of the hanging-outlet. This supporting force can directly offset part of the downward torque generated by the weight of the air conditioner. At the same time, the lateral sidewall of the hook is tightly fitted with the inner wall of the hanging-outlet, which can limit the horizontal displacement of the supporting profile and prevent the supporting profile from becoming unbalanced due to displacement. This stress point mainly bears shear force and part of the radial pressure, and can share about 40%-60% of the air conditioner's weight load, effectively preventing the initial downward movement of the free end of the supporting profile.

[0010] The function of the second stress point (bolt-locating hole threaded fit): The bolts passing through locating holes one and two are threaded into both locating holes, forming a rigid connection. When the supporting profile still has a residual tendency to rotate, the bolt will bear the remaining 40%-60% of the gravity load—the bolt's own shear strength can resist the shear force generated by the rotation of the supporting profile, and the threaded fit between the bolt and the locating hole can provide an upward pulling force, further preventing the supporting profile from rotating downward, while also preventing the hook from deforming or breaking due to excessive load alone.

[0011] Assisted force coordination: The supporting profile, fixed profile, and bearing profile form a stable triangular structure. Utilizing the mechanical property of the triangle's "non-deformable" nature, part of the gravity transmitted by the bearing profile is distributed to the connection point of the fixed and supporting profiles, reducing the overall stress intensity at the connection point and further reducing the risk of damage at the connection.

[0012] Through the synergistic effect of the two stress points, the load generated by the gravity of the air conditioner is evenly distributed, avoiding the stress concentration problem in the traditional single stress point connection, and ensuring long-term stable stress at the connection between the fixed profile and the supporting profile.

[0013] Beneficial effects Significantly effective in preventing damage: The dual stress points share the weight load of the air conditioner, avoiding stress concentration at a single connection point. This effectively prevents damage such as bolt stripping, profile cracking, and hook deformation at the connection between the fixed and supporting profiles, extending the service life of the bracket.

[0014] Easy and efficient installation: When connecting the fixed profile and the supporting profile, the pre-position can be achieved by the snap-fit ​​of the hook and the hanging hole. There is no need for manual support to align the hole for a long time. Then the bolt fixing can be completed quickly, which greatly improves the assembly efficiency.

[0015] Strong connection stability: The hook fits tightly with the hanging hole, and the bolt and the positioning hole are threaded together. The double connection structure ensures that the fixed profile and the supporting profile are not loose. At the same time, the triangular structure further enhances the stability of the overall bracket and prevents the air conditioner from shifting or shaking after installation.

[0016] High versatility and safety: It is compatible with air conditioners of different weights (tens of kilograms to hundreds of kilograms), and the dual force point design greatly reduces the risk of the air conditioner falling off due to bracket damage, thus improving the safety factor of air conditioner installation.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4 As shown; An air conditioner bracket.

[0020] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "Air conditioners (especially cabinet air conditioners or high-power wall-mounted air conditioners) typically weigh tens to hundreds of kilograms. During long-term use, the weight of the air conditioner continuously acts on the supporting profile, causing significant stress concentration at the connection between the fixed profile and the supporting profile. A single bolt bearing point must bear the shear force and radial pressure from the entire weight, which easily leads to the following problems: First, the bolt is prone to thread stripping, bolt shank deformation, or even breakage under long-term load; second, cracking and deformation occur at the edge of the profile connection due to stress concentration, resulting in a decrease in connection strength; in severe cases, it can cause the supporting profile to tilt and the air conditioner to fall off, posing a significant safety hazard. In addition, single bearing point connections require precise alignment of holes during installation, resulting in low assembly efficiency and difficulty in meeting the dual requirements of bracket stability and convenience in actual installation scenarios." Considering practical use, this problem is clearly real and difficult to solve. Therefore, to solve this technical problem, an air conditioner bracket is provided.

[0021] Example 1 like Figure 1-4 As shown in the figure; The air conditioner bracket in this embodiment includes a fixed profile 1, a supporting profile 2, and a supporting profile 3. The specific structure and connection method of each component are as follows: The fixing profile 1 has 3-5 first mounting holes 11, each with a diameter of 8-12mm. Expansion bolts are passed through these holes to securely fix the fixing profile 1 to the wall or air conditioner mounting surface. The fixing profile 1 also has an integrally formed L-shaped hook 13 with a positioning hole 12. The L-shaped hook 13 has a bending angle of 90°, and its length is designed according to the weight of the air conditioner (typically 20-30mm) to ensure sufficient load-bearing strength.

[0022] The supporting profile 2 has 2-3 mounting holes 21 for installing air conditioners. These mounting holes 21 are arranged in a straight line along the length of the supporting profile 2, with a spacing of 50-80mm between adjacent mounting holes to accommodate different air conditioner mounting positions. The supporting profile 2 also has a hanging opening 22 that matches the hook 13, and a second positioning hole 23 that matches the first positioning hole 12. The first positioning hole 12 and the second positioning hole 23 have the same diameter (both 6-10mm) and are clearance-fitted, with a clearance range of 0.1-0.3mm, facilitating quick alignment during assembly. When the hook 13 engages with the hanging opening 22, the depth to which the hook 13 extends into the hanging opening 22 is not less than half its own length, and the outer wall of the hook 13 fits tightly against the inner wall of the hanging opening 22 without any noticeable gap.

[0023] The supporting profile 3 is a rectangular cross-section metal profile (thickness 3-5mm). Its connection position with the fixed profile 1 is located at one end of the length direction of the fixed profile 1, and its connection position with the supporting profile 2 is located at the middle of the end of the supporting profile 2 away from the fixed profile 1. Both ends of the supporting profile 3 are provided with through holes that are compatible with bolts. The bolts are used to fix it to the fixed profile 1 and the supporting profile 2 respectively, so that the fixed profile 1, the supporting profile 2 and the supporting profile 3 form a stable triangular structure.

[0024] The assembly and use process of the air conditioner bracket in this embodiment is as follows: Fixing the fixing profile 1: By passing expansion bolts through the first mounting hole 11 of the fixing profile 1, the fixing profile 1 is fixed to the wall (or the preset mounting surface), ensuring that the fixing profile 1 is tightly attached to the wall and there is no looseness.

[0025] Pre-positioning support profile 2: Align the hanging opening 22 of the support profile 2 with the hook 13 of the fixed profile 1, and slowly push the support profile 2 so that the hook 13 extends into the hanging opening 22 until the outer wall of the hook 13 is tightly fitted with the inner wall of the hanging opening 22. At this time, the positioning hole 12 and the positioning hole 23 are automatically aligned.

[0026] Fixed support profile 2: Take a suitable bolt (usually M6-M10 specification), pass it through positioning hole 12 and positioning hole 23, and use a wrench to tighten the bolt so that the bolt forms a threaded engagement with positioning hole 12 and positioning hole 23, thus completing the dual force point connection between fixed profile 1 and support profile 2.

[0027] Install the support profile 3: Fix one end of the support profile 3 to one end of the fixed profile 1 along its length with bolts, and fix the other end of the support profile 2 to the middle of the end away from the fixed profile 1 with bolts. After tightening the bolts, the triangular structure is formed.

[0028] Install the air conditioner: Align the mounting feet of the air conditioner body with the mounting holes 21 of the supporting profile 2, and fix the air conditioner to the supporting profile 2 with bolts to complete the overall installation.

[0029] During use, the weight of the air conditioner is transmitted to the two stress points through the supporting profile 2: the hook 13 and the hanging opening 22 share part of the shear force and support force, the bolts share the remaining load, and the triangular structure helps to disperse the force, ensuring long-term stability of the connection and no risk of damage.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
