Description

Technical Field

[0001] The invention relates to the field of air conditioners, and in particular to a shaft-connecting fixing structure and an air conditioner. Background Art

[0002] Generally speaking, an air conditioner is a device that uses a compressor and a condenser, an expansion device and an evaporator to cool or heat a room. If a purification unit for purifying the air is installed, it can also have the function of purifying the room. There are many types of purification units installed in the air conditioner, especially a detachable filter for filtering foreign matter in the air. When the air conditioner is operated, the motor inside it drives the shaft to rotate, and the shaft causes the support mechanism inside the air conditioner to move synchronously.

[0003] In the prior art, when the air conditioner is working, the motor drives the connecting shaft to rotate. Since the connecting shaft is long, the middle part of the connecting shaft is easily deformed. Summary of the invention

[0004] In view of this, the present invention aims to provide a coupling fixing structure and an air conditioner to solve the problem that when the existing air conditioner is working, the motor drives the coupling to rotate, and the middle part of the coupling is prone to deformation due to its long length.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A coupling fixing structure includes a middle frame and a connecting plate arranged in the middle of the middle frame. An arc groove for accommodating the coupling is arranged at the lower part of the connecting plate. The coupling can rotate in the arc groove. A rotating part is arranged in the middle of the coupling, and the axial movement of the coupling in the arc groove can be limited by the rotating part.

[0007] By adding a rotating part in the middle of the connecting shaft and fixing the rotating part through the mounting part, the connecting shaft is fixed to prevent the middle part of the connecting shaft from being deformed due to excessive length when the air conditioner is working. At the same time, the rotation of the connecting shaft in the arc groove is converted into the movement of the connecting shaft driven by the rotating part, thereby reducing the friction between the connecting shaft and the arc groove and increasing or decreasing the transmission efficiency of the connecting shaft.

[0008] Furthermore, the rotating member is cylindrical or square-tube-shaped, and at least one guide rib is provided in the middle of the outer side of the rotating member.

[0009] The rotating member is a hollow structure, and the connecting shaft passes through the rotating member, so that the rotating member is in direct contact with the arc groove.

[0010] Furthermore, an open groove is provided in the middle of the arc-shaped groove, and the guide rib of the rotating member is placed in the open groove.

[0011] The guide rib is placed in the open groove, so that the open groove plays a role in limiting the rotating member, thereby preventing the rotating member from being displaced when the air conditioner is working.

[0012] Furthermore, it also includes a mounting piece, which is buckled on the top of the arc groove and cooperates with the arc groove to form a rotation space for the connecting shaft.

[0013] The mounting member is used to limit the two ends of the rotating member and support the rotating member to rotate between the arc groove and the mounting member.

[0014] Furthermore, guide plates are provided inside the mounting member, and accommodating grooves are formed between the guide plates, and the guide ribs are placed in the accommodating grooves.

[0015] The upper end of the guide rib is limited by the accommodating groove, which can more effectively ensure the limiting effect of the rotating member and prevent the rotating member from having a large displacement during operation.

[0016] Furthermore, the widths of the accommodating groove and the opening groove are both greater than the thickness of the guide rib.

[0017] When the air conditioner is just turned on, the motor is turned on, driving the connecting shaft to start moving. Due to the inertial force, the rotating part and the arc groove are easily collided, causing damage to the accommodating groove or the rotating part. By setting a smaller gap in the accommodating groove, the rotating part can unload the inertial force, thereby preventing the rotating part or the middle frame from being damaged.

[0018] Furthermore, the mounting member includes a top plate, a rib plate is arranged above the top plate, an arc plate is arranged above the rib plate, a filter slot is formed between the rib plate, the arc plate and the top plate, and the width of the filter slot formed between the rib plate, the arc plate and the top plate is the same as the width of the slide groove on the connecting plate.

[0019] By arranging a filter slot on the mounting member, the filter slot formed between the rib plate, the arc plate and the top plate is connected to the slide groove on the connecting plate as a whole, which is convenient for installing and fixing the filter.

[0020] Furthermore, a fixing seat is installed at the bottom of the connecting plate, a sliding groove is opened on the side wall of the connecting plate, a boss is arranged on one side of the fixing seat, and a positioning block is arranged on the boss.

[0021] The mounting piece is limited by the positioning block to prevent the mounting piece from falling off during operation and causing damage to the coupling.

[0022] Furthermore, a limiting plate is arranged between the guide plates, and the mounting member is inserted into the positioning block so that the limiting plate cooperates with the positioning block to position the mounting member.

[0023] The mounting part is limited by the cooperation between the positioning block and the positioning plate, and the positioning plate can be set at different positions between the guide plates according to different models of air conditioners to position the mounting parts in air conditioners of different models, so as to prevent the mounting parts from loosening and disengaging from the connecting plate when the air conditioner is working, causing the guide plate to disengage from the arc groove and damaging the connecting shaft.

[0024] Furthermore, an air conditioner includes the aforementioned coupling fixing structure.

[0025] Compared with the prior art, the coupling fixing structure and air conditioner described in the present invention have the following advantages: the coupling is supported by installing a rotating part on the coupling, thereby reducing the rotational friction between the coupling and the arc groove and improving the transmission efficiency of the coupling; the rotating part is fixed by setting a mounting part to prevent the rotating part from detaching from the arc groove in the middle frame during air conditioning, thereby causing damage to the coupling.

[0038] 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.

[0039] Embodiment 1:

[0040] See attached Figure 1 , a coupling fixing structure comprises a middle frame 1 and a connecting plate 2 arranged in the middle of the middle frame 1, the connecting plate 2 is a plate-like structure, the upper part is tightly attached to the inner wall of the middle frame 1, and the lower part is bent toward the inside of the middle frame 1, and a filter screen chute is opened on the side wall of the connecting plate 2, the bottom part of the middle frame 1 is recessed to form an arc groove 4, and the arc groove 4 extends along the length direction of the middle frame 1, and the coupling 8 is placed in the arc groove 4 and can rotate along the arc groove 4, and the arc groove 4 is close to The connecting plate is provided with a fixed seat 3 and a boss 5 on both sides, the fixed seat 4 is a rectangular structure, and a chamfer is opened on one side close to the arc groove 4, and the boss 5 is a rectangular structure, and a rotating member 9 is arranged in the middle of the coupling 8, and a mounting member 7 is arranged above the rotating member 9, and the mounting member 7 cooperates with the arc groove 4 to limit the rotating member 9 and support the rotating member 9 to rotate.

[0041] Specifically, the rotating member 9 is a hollow tubular structure, and the connecting shaft 8 can be a connecting shaft or a circular connecting shaft. Taking the connecting shaft as an example, the connecting shaft 8 is inserted into the rotating member 9, and the rotating member 9 is placed in the middle of the arc groove 4. When the motor drives the connecting shaft 8 to rotate, since the four corners of the connecting shaft 8 are clamped on the inner wall of the rotating member 9, when the motor rotates, the connecting shaft 8 drives the rotating member 9 to rotate synchronously, and the rotation of the connecting shaft 8 in the arc groove 4 is converted into the rotation of the rotating member 9 in the arc groove 4, which reduces the friction between the connecting shaft 8 and the arc groove 4 and improves the transmission efficiency of the connecting shaft 8. At the same time, the position of the rotating member 9 is limited by the cooperation of the mounting member 7 and the arc groove 4, so as to prevent the rotating member 9 from having a large displacement during the operation of the air conditioner, causing the rotating member 9 to lose its function and fail to protect the middle of the connecting shaft 8.

[0042] The use of the rotating member 9 improves the transmission efficiency of the coupling 8, and the use of the mounting member 7 fixes the rotating member 9 to prevent the rotating member 9 from being displaced during the operation of the air conditioner, causing the rotating member 9 to lose its function.

[0044] On the basis of Example 1, the structure of the rotating member 9 described in Example 1 is further optimized:

[0045] For details, see the attached Figure 8 The rotating member 9 is cylindrical or square-tube shaped, and a guide rib 901 is provided on the rotating member 9 .

[0046] By providing a guide rib 901 on the rotating member 9, the position of the rotating member 9 is fixed by utilizing the cooperation between the guide rib 901, the arc groove 4 and the mounting member 7, thereby preventing the rotating member 9 from being displaced when the air conditioner is working.

[0047] Preferably, see the attached Fig. 9 Two guide ribs 901 are provided on the rotating member 9. By providing two guide ribs 901 on the rotating member 9, the movable distance of the guide rib 901 in the opening groove is further reduced.

[0048] Example 3

[0049] On the basis of Example 1, the structure of the rotating member 9 described in Example 1 is further optimized:

[0050] Specifically, an open groove 401 is provided in the middle of the arc groove 4, and the guide rib 901 of the rotating member 9 is placed in the open groove 401. The depth of the open groove 401 is greater than the height of the guide rib 901. Both ends of the rotating member 9 are in contact with the two side edges of the open groove 401, so that the guide rib 901 is suspended in the open groove, and the rotating member 9 is in direct contact with the arc groove 4. At the same time, the width of the open groove 401 is greater than the thickness of the guide rib 901, so that the open groove 401 limits the guide rib 901. On the one hand, the guide rib 901 can only rotate in the open groove, and there will be no contact between the guide rib 901 and the two side edges of the open groove 401, so that there is no friction resistance during the rotation process. On the other hand, the rotating member 9 is prevented from being separated from the mounting member 7, so that the rotating member 9 loses its function.

[0051] Example 4

[0052] On the basis of Example 1, the structure of the coupling fixing structure described in Example 1 is further optimized:

[0053] For details, see the attached Figure 5-7 The coupling fixing structure also includes a mounting member 7, which is buckled on top of the arc groove 4 and cooperates with the arc groove 4 to form a rotation space for the coupling 8. A guide plate 704 is provided at the middle position inside the mounting member 7. There are two guide plates 704. The guide plates 704 are arc-shaped plates, which are formed by the mounting member 7 protruding outward. A receiving groove 707 is formed between the two guide plates 704, and the guide rib 901 is placed in the receiving groove 707.

[0054] The guide plate 704 is a curved structure, and the curvature of the guide plate 704 is the same as the curvature of the arc groove 4. Through the cooperation between the guide plate 704 and the arc groove 4, the connecting shaft 8 rotates between the guide plate 704 and the arc groove 4. The upper end of the guide rib 901 is limited by the accommodating groove 707. By limiting the upper and lower ends of the guide rib 901, the rotating member 9 is prevented from detaching from the mounting member 7 during operation.

Due to the inertial force, the rotating member 9 is easily collided with the arc groove 4, causing damage to the accommodating groove 707 or the rotating member 9. By setting a smaller gap in the accommodating groove 707, the rotating member 9 can be unloaded from the inertial force, thereby preventing the rotating member 9 or the middle frame 1 from being damaged.
