Detailed implementation manners

[0030] An embodiment of the present application provides a pipe clamp 100. Please refer to Figure 3 and Figure 4 . The pipe clamp 100 includes a housing 10 and a flexible clamping pad 20.

[0031] Please continue to refer to Figure 3 and Figure 4 . The housing 10 is provided with at least two mounting grooves 10b having avoidance openings 10a and first positioning portions 11 corresponding to the mounting grooves 10b one by one. That is to say, the number of the mounting grooves 10b can be two or greater than two. At the same time, the number of the first positioning portions 11 is the same as the number of the mounting grooves 10b, and the first positioning portions 11 respectively corresponding to each mounting groove 10b cooperate. The mounting grooves 10b penetrate through the housing 10, and the avoidance openings 10a are located on one side of the mounting grooves 10b.

[0032] The flexible clamping pads 20 correspond to the mounting grooves 10b one by one. The flexible clamping pads 20 are provided with second positioning portions 21 and clamping grooves 20b having clamping openings 20a. The clamping grooves 20b penetrate through the flexible clamping pads 20, and the clamping openings 20a are located on one side of the clamping grooves 20b. The flexible clamping pads 20 are clamped in the corresponding mounting grooves 10b, and the second positioning portions 21 cooperate with the corresponding first positioning portions 11 to prevent the flexible clamping pads 20 from rotating in the mounting grooves 10b, and the avoidance openings 10a avoid the clamping openings 20a.

[0033] Specifically, the flexible clamping pad 20 refers to a clamping pad that can generate a certain elastic deformation. Exemplarily, the flexible clamping pad 20 can be a rubber part, a silicone part, etc.

[0034] The number of the flexible clamping pads 20 is the same as the number of the mounting grooves 10b. Each flexible clamping pad 20 is respectively clamped in the corresponding mounting groove 10b through the avoidance opening 10a of the corresponding mounting groove 10b, so as to play a constraining role on the corresponding flexible clamping pad 20 through the mounting groove 10b.

[0035] The hardness of the housing 10 can be greater than the hardness of the flexible clamping pad 20. Exemplarily, the housing 10 can be a plastic part. For example, the housing 10 can be a polypropylene plastic part.

[0036] In addition, when the housing 10 is a plastic part, the housing 10 can be processed by injection molding.

[0037] The second positioning portion 21 cooperates with the corresponding first positioning portion 11 to prevent the flexible clamping pad 20 from rotating within the installation groove 10b, which means that after the flexible clamping pad 20 is snapped into the corresponding installation groove 10b, the second positioning portion 21 can, by cooperating with the corresponding first positioning portion 11, play a role in preventing the flexible clamping pad 20 from rotating, so as to prevent the flexible clamping pad 20 from rotating circumferentially within the installation groove 10b along the installation groove 10b.

[0038] Exemplarily, please refer to FIGS. 5 and Figure 6 , the first positioning portion 11 can be a positioning hole, and the second positioning portion 21 is a positioning post that is inserted and mated with the positioning hole, and the housing 10 and the flexible clamping pad 20 are positioned and connected through the positioning hole and the positioning post.

[0039] In some other embodiments, the first positioning portion 11 can also be a positioning post, and the second positioning portion 21 is a positioning hole that is inserted and mated with the positioning post.

[0040] The avoidance opening 10a avoiding the bayonet 20a means that the bayonet 20a is exposed at the avoidance opening 10a, and the avoidance opening 10a does not block the bayonet 20a.

[0041] The embodiment of the present application also provides an outdoor air conditioner. Please refer to Figures 1 to 4 , the outdoor air conditioner includes a first pipe body 200, a second pipe body 300, and the pipe clamp 100 provided in any embodiment of the present application. The first pipe body 200 is snap-fitted with the card slot 20b of the flexible clamping pad 20 within one of the installation grooves 10b, and the second pipe body 300 is snap-fitted with the card slot 20b of the flexible clamping pad 20 within the other installation groove 10b. That is to say, the pipe clamp 100 is used to be snap-fitted with the first pipe body 200 and the second pipe body 300 respectively.

[0042] Figure 1 and Figure 2 The shown outdoor air conditioner only needs to fix the two pipe bodies, namely the first pipe body 200 and the second pipe body 300, through the pipe clamp 100. Therefore, only two installation grooves 10b and two flexible clamping pads 20 are provided on the housing 10 of the pipe clamp 100. The first pipe body 200 is snapped into the card slot 20b of the flexible clamping pad 20 from the bayonet 20a of the flexible clamping pad 20 within one of the installation grooves 10b, and the second pipe body 300 is snapped into the card slot 20b of the flexible clamping pad 20 from the bayonet 20a of the flexible clamping pad 20 within the other installation groove 10b.

[0043] It can be understood that when the number of pipe bodies clamped by the same pipe clamp 100 is greater than two, the number of installation grooves 10b and flexible clamping pads 20 of the pipe clamp 100 also needs to be increased accordingly, and each pipe body is respectively snap-fitted with the card slot 20b of the flexible clamping pad 20 within the corresponding installation groove 10b.

[0044] An embodiment of the present application further provides an air conditioner, which includes the outdoor unit of the air conditioner provided in any embodiment of the present application.

[0045] In the pipe clamp 100 of the embodiment of the present application, by providing the housing 10 and the flexible clamping pad 20, and clamping the flexible clamping pad 20 in the corresponding installation groove 10b provided on the housing 10, a restraining effect can be exerted on the flexible clamping pad 20. Therefore, when the pipe clamp 100 is used to be respectively clamped with the first pipe body 200 and the second pipe body 300 of the outdoor unit of the air conditioner, the flexible clamping pad 20 provided in the installation groove 10b can provide sufficient clamping force for the first pipe body 200 and the second pipe body 300. Therefore, without further fixing with a cable tie, it can be ensured that the pipe clamp 100 can be reliably clamped with the first pipe body 200 and the second pipe body 300. In addition, since the first positioning portion 11 is provided on the housing 10 and the second positioning portion 21 is provided on the flexible clamping pad 20, through the cooperation of the first positioning portion 11 and the second positioning portion 21, the flexible clamping pad 20 can be prevented from rotating circumferentially along the installation groove 10b in the installation groove 10b. Therefore, during the process of respectively clamping the first pipe body 200 and the second pipe body 300 into the clamping grooves 20b of the corresponding flexible clamping pads 20, it can be avoided that the flexible clamping pad 20 affects the clamping of the first pipe body 200 and the second pipe body 300 into the clamping grooves 20b of the corresponding flexible clamping pads 20 due to rotation, thereby facilitating the installation of the pipe clamp 100. That is to say, the pipe clamp 100 of the embodiment of the present application not only has high reliability but also is convenient for installation.

[0046] In addition, in the refrigerant pipeline of the outdoor unit of the air conditioner, the pipe body with relatively large vibration is usually called the dynamic pipe, and the pipe body with relatively small vibration or no vibration is called the static pipe. Among them, the dynamic pipes include but are not limited to the pressure switch connection pipe, the solenoid valve connection pipe, the electronic expansion valve connection pipe, the condenser thin connection pipe, etc., and the static pipes include but are not limited to the return connection pipe, the four-way valve connection pipe, the condenser thick connection pipe, etc. The vibrations of both the dynamic pipes and the static pipes will cause problems such as excessive noise and stress concentration, and in severe cases, the pipe body will break.

[0047] Therefore, the pipe clamp 100 of the embodiment of the present application can be used to fix the dynamic pipes and the static pipes. For example, please refer to Figure 1 and Figure 2 , the first pipe body 200 can be a dynamic pipe, and the second pipe body 300 can be a static pipe. Since the pipe clamp 100 of the embodiment of the present application has high reliability, after the static pipe and the dynamic pipe are fixed through the pipe clamp 100, the noise can be reduced to a certain extent, and the hidden danger of pipe body breakage can be reduced.

[0048] In addition, it should be noted that the pipe clamp 100 of the embodiment of the present application is not limited to being used in the outdoor unit of the air conditioner, and the pipe clamp 100 can be applied to any device that needs to fix the pipe body.

[0049] In one embodiment, please refer toFigures 4 to 6 The first positioning portion 11 and the avoidance opening 10a can be respectively arranged on opposite sides of the installation groove 10b. After the flexible clamping pad 20 enters the installation groove 10b from the avoidance opening 10a, the second positioning portion 21 on the flexible clamping pad 20 can automatically cooperate with the first positioning portion, thereby effectively improving the assembly efficiency of the pipe clamp 100.

[0050] In one embodiment, please refer to Figure 3 and Figure 4 , the housing 10 can be provided with bending portions 12 corresponding one-to-one to the installation grooves 10b, and each bending portion 12 is bent to enclose the corresponding installation groove 10b.

[0051] The bending angle of the bending portion 12 only needs to satisfy that it can enclose the installation groove 10b for accommodating the flexible clamping pad 20. Preferably, the bending angle of the bending portion 12 can be greater than 180°, so as to provide a more reliable pressing force on the flexible clamping pad 20 arranged in the installation groove 10b, thereby improving the structural stability of the pipe clamp 100.

[0052] In one embodiment, please refer to Figure 4 , the bending portions 12 respectively have first flanges 121 formed by turning over in a direction away from the installation groove 10b on opposite sides of the avoidance opening 10a. During the process of the flexible clamping pad 20 entering the installation groove 10b from the avoidance opening 10a, the two first flanges 121 on both sides of the avoidance opening 10a can guide the flexible clamping pad 20 into the installation groove 10b, thereby facilitating the clamping of the flexible clamping pad 20 into the installation groove 10b.

[0053] In some other embodiments, the bending portion 12 can also be provided with a first flange only on one of the opposite sides of the avoidance opening 10a.

[0054] Please refer to Figure 3 and Figure 4 , the flexible clamping pad 20 can also have second flanges 22 arranged at the bayonet 20a and corresponding one-to-one to the first flanges 121. The second flanges 22 are turned over in a direction away from the card slot 20b, and the second flanges 22 are correspondingly clamped with the first flanges 121, so that the flexible clamping pad 20 can be more firmly fixed on the housing 10, and further increase the structural stability of the pipe clamp 100.

[0055] In one embodiment, please refer to Figure 4 , the housing 10 further includes a connecting portion 13, and each bending portion 12 is arranged on the periphery of the connecting portion 13 and is connected to the connecting portion 13.

[0056] Please refer to Figure 5, reinforcing ribs 14 can be provided on the outer shell 10. The reinforcing ribs 14 are provided on the connecting portion 13 and on the side of each bending portion 12 facing away from the mounting groove 10b to improve the structural strength of the pipe clamp 100.

[0057] Specifically, the setting manner of the reinforcing ribs 14 is not limited. Exemplarily, it can be Figure 5 as shown, a single reinforcing rib 14 extends to the connecting portion 13 and each bending portion 12, or at least some of the plurality of reinforcing ribs 14 extend to the connecting portion 13 and each bending portion 12, or reinforcing ribs 14 are respectively provided on the side of the connecting portion 13 and each bending portion 12 facing away from the mounting groove 10b.

[0058] Please refer to Figure 4 , a partial area of the connecting portion 13 can be recessed to form a groove 13a. Compared with the connecting portion 13 without the groove 13a, such as a connecting portion 13 in a plate-like or block-like structure, the connecting portion 13 with the groove 13a has higher structural strength and can better adapt to the working condition of the pipe body vibration. In addition, when the outer shell 10 is made by injection molding, it can also prevent the shrinkage of the connecting portion 13 to a certain extent. In addition, setting the groove 13a on the connecting portion 13 can also reduce the manufacturing cost of the outer shell 10.

[0059] In one embodiment, please refer to Figure 5 and Figure 6 , the flexible clamping pad 20 includes a clamping portion 23 and two limiting portions 24. The clamping groove 20b penetrates through the clamping portion 23 in the first direction. The two limiting portions 24 are respectively arranged at opposite ends of the clamping portion 23 in the first direction and are annularly arranged on the outer peripheral side of the clamping portion 23. The clamping portion 23 is clamped in the mounting groove 10b, and both of the two limiting portions 24 are located outside the mounting groove 10b and face the portion of the outer shell 10 on the circumferential side of the mounting groove 10b. The two limiting portions 24 can be in contact with the outer shell 10 or form a gap with the outer shell 10.

[0060] The purpose of setting the two limiting portions 24 is that the two limiting portions 24 can respectively limit the outer shell 10 from opposite ends of the outer shell 10, so as to better avoid the movement of the flexible clamping pad 20 along the penetrating direction of the mounting groove 10b through the outer shell 10.

[0061] In one embodiment, please refer to Figure 3 , a plurality of racks 25 arranged at intervals along the circumferential direction of the clamping groove 20b can be provided on the inner side wall of the clamping groove 20b.

[0062] A plurality of racks 25 surround the circumferential side of the first tube body 200 or the second tube body 300 to form a plurality of force-bearing contact surfaces, so that the elastic pressure exerted by the flexible clamping pad 20 on the first tube body 200 or the second tube body 300 is concentrated on the plurality of force-bearing contact surfaces, effectively improving the connection stability of the flexible clamping pad 20 to the first tube body 200 and the second tube body 300.
