Description

Technical Field

[0001] The utility model relates to the technical field of expansion valve connecting brackets and discloses an expansion valve connecting bracket for an automobile air-conditioning evaporator. Background Art

[0002] The expansion valve is an important component in the refrigeration system. Its main function is to reduce the pressure and temperature of the refrigerant through throttling, and at the same time adjust the flow of the refrigerant to ensure the effective operation of the refrigeration system. The expansion valve is usually installed between the liquid storage cylinder and the evaporator, so that the medium-temperature and high-pressure liquid refrigerant passes through its throttling to become low-temperature and low-pressure wet steam, and then absorbs heat in the evaporator to achieve the refrigeration effect.

[0003] The expansion valve of the existing automobile air-conditioning evaporator is directly arranged on the pipeline of the evaporator. When the automobile air-conditioning is running, the compressor will vibrate, which in turn drives the expansion valve to vibrate, which can easily cause the connection between the expansion valve and the evaporator to break, and the expansion valve will generate noise when it vibrates.

[0004] Therefore, there is a need for an expansion valve connecting bracket for an automobile air-conditioning evaporator. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art that when the automobile air conditioner is running, the compressor will vibrate, which will in turn drive the expansion valve to vibrate, which may easily lead to breakage at the connection between the expansion valve and the evaporator, and noise will be generated when the expansion valve vibrates, the utility model provides an expansion valve connecting bracket for the automobile air conditioner evaporator.

[0006] The utility model provides the following technical solution: an expansion valve connecting bracket of an automobile air-conditioning evaporator, comprising a connecting bracket, a placing hole is opened on the connecting bracket, a first mounting hole is opened on the connecting bracket, and a second mounting hole is opened on the connecting bracket.

[0007] Furthermore, it also includes a fixed plate, a screw, a fixed seat and a mounting plate. The left and right sides of the connecting frame are fixedly connected to the fixed plates, the left and right sides of the mounting plate are fixedly connected to the fixed seats, the fixed seats are rotatably provided with screws, and the screws are threadedly connected to the fixed plates.

[0008] Furthermore, it also includes a supporting frame, a limiting frame and an elastic member. Two supporting frames are fixedly connected to the connecting frame. The limiting frame is slidably arranged on the supporting frame. Two elastic members are sleeved on the limiting frame. The two ends of the elastic member are respectively connected to the supporting frame and the limiting frame.

[0009] Furthermore, a rubber pad is included, and a rubber pad is arranged at the bottom of the connecting frame.

[0010] Furthermore, the contact surface between the limiting frame and the pipeline is an inclined surface.

[0011] Furthermore, the connecting frame is made of stainless steel.

[0012] Compared with the prior art, the utility model provides an expansion valve connecting bracket for an automobile air-conditioning evaporator, which has the following beneficial effects: 1. By placing the expansion valve on the connecting bracket, inserting the bolts into the first mounting hole and the second mounting hole, and tightening the bolts to fix the expansion valve on the connecting bracket, the compressor is prevented from causing the expansion valve to vibrate, resulting in high noise and breakage of the expansion valve connection.

[0013] 2. By rotating the screw rod to move the fixing plate, the fixing plate drives the connecting frame to move, thereby adjusting the height of the connecting frame, thereby adjusting the height of the connecting frame according to usage requirements, and improving the usability of the expansion valve connecting bracket.

[0014] 3. When the pipeline is no longer extruding the limit frame, the elastic member returns to its original state and drives the limit frame to move toward the side close to each other, thereby limiting the pipeline and preventing the pipeline from moving. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: An expansion valve connecting bracket for an automobile air-conditioning evaporator, see Figure 1-Figure 4, including a connecting frame 1. The connecting frame 1 is made of stainless steel. Stainless steel has good corrosion resistance and is not easy to rust, thereby extending the service life of the connecting frame 1. A placement hole 2 is opened on the connecting frame 1, a first mounting hole 3 is opened on the connecting frame 1, and a second mounting hole 4 is opened on the connecting frame 1. A rubber pad 12 is arranged at the bottom of the connecting frame 1. The rubber pad 12 reduces the pressure between the car air conditioner and the connecting frame 1 to avoid indentation.

[0022] When installing the expansion valve, first fix the connecting frame 1 at a suitable position inside the car air conditioner, then place the expansion valve on the connecting frame 1, insert the bolts into the first mounting hole 3 and the second mounting hole 4, tighten the bolts to fix the expansion valve on the connecting frame 1, and avoid the compressor driving the expansion valve to vibrate, resulting in high noise and breakage of the expansion valve connection, then insert the pipeline into the placement hole 2, enter to limit the pipeline, and then connect the pipeline to the expansion valve.

[0023] Example 2: Based on Example 1, please refer to Figure 1 and 3 The left and right sides of the connecting frame 1 are both provided with fixing plates 5 by welding, the left and right sides of the mounting plate 8 are both provided with fixing seats 7 by welding, and the fixing seats 7 are rotatably provided with screws 6, which are threadedly connected to the fixing plates 5.

[0024] Before using the expansion valve connecting bracket, first install the mounting plate 8 at a suitable position inside the automobile air conditioner, then rotate the screw 6 to move the fixing plate 5, so that the fixing plate 5 drives the connecting frame 1 to move, and then adjust the height of the connecting frame 1, thereby adjusting the height of the connecting frame 1 according to usage requirements, improving the usability of the expansion valve connecting bracket, and after adjusting the connecting frame 1 to a suitable height, stop rotating the screw 6.

[0025] See also Figure 1 and Figure 4 Two support frames 9 are arranged on the connecting frame 1 by welding, and a limit frame 10 is slidably arranged on the support frame 9. Two elastic members 11 are sleeved on the limit frame 10. The two ends of the elastic member 11 are respectively connected to the support frame 9 and the limit frame 10. The contact surface between the limit frame 10 and the pipeline is an inclined surface, so that the pipeline can squeeze the limit frame 10 and move to the side away from each other.

[0026] After the expansion valve is fixed on the connecting frame 1, the pipeline is inserted into the placement hole 2, so that the pipeline squeezes the limit frame 10 and moves to the side away from each other. The elastic member 11 is compressed accordingly. After the pipeline is completely inserted into the placement hole 2, the pipeline no longer squeezes the limit frame 10, and the elastic member 11 returns to its original state, driving the limit frame 10 to move to the side close to each other, thereby limiting the pipeline and preventing the pipeline from moving.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
