[0002] At present, the compressor foot pad of an air conditioner is mostly fixed by bolts and nuts. For example, a compressor base is sleeved on a plurality of foot pads, and the foot pads are placed on a bottom plate. A threaded hole or a through hole is arranged in the foot pad, and the end of the foot pad that protrudes upward from the base is fixed by a bolt and a nut, and the bolt passes through the foot pad and the bottom plate, thereby locking the compressor base, the foot pad and the bottom plate.

[0003] However, the bolt and nut fixing mode has the following problems: in the production operation, an electric wrench is needed to tighten the bolt and the nut, resulting in slow assembly and low production efficiency. SUMMARY

[0004] The present application solves the problem of low assembly efficiency of the fixing mode of the existing compressor foot pad.

[0005] To solve the above problems, the present application provides a compressor foot pad fixing device, a compressor and an air conditioner.

[0006] In one aspect, the present application provides a compressor foot pad fixing device, comprising: a foot pad; an upper fixing member, which is sleeved on the foot pad and cooperates with the foot pad; and a lower fixing member, which is arranged on the lower side of the upper fixing member and is buckled with the upper fixing member.

[0007] Compared with the prior art, the technical effects achieved by the technical scheme are as follows: when the leg of the compressor foot pad fixing device is fixed with the foot pad, only the upper fixing member on the leg needs to be sleeved on the foot pad. On the basis that the lower fixing member is fixed with other devices, the upper fixing member and the foot pad can also be fixed at the same time, thereby facilitating the fixation of the foot pad and improving the assembly efficiency of the compressor and the production efficiency of the air conditioner.

[0008] In one embodiment of the present application, the upper fixing member is provided with at least one cooperating protrusion, and the cooperating protrusion is located on the side wall of the upper fixing member; and the lower fixing member is provided with at least one cooperating opening, and the cooperating protrusion is inserted into the cooperating opening.

[0009] The technical effects achieved by the technical scheme are as follows: after the cooperating protrusion is inserted into the cooperating opening, the upper fixing member and the lower fixing member cannot move along the vertical direction; and in the sleeved state of the upper fixing member and the lower fixing member, the upper fixing member and the lower fixing member also cannot move along the direction perpendicular to the side wall.

[0010] In one embodiment of the present application, the fitting protrusion passes through the fitting opening to the other side of the fitting opening away from the side wall; the fitting protrusion is provided with a locking member, which is located at the other side.

[0011] The technical effects achieved by the technical scheme are as follows: the locking member is used to prevent the fitting protrusion from sliding out of the fitting opening, thereby further improving the stability of the connection between the upper fixing member and the lower fixing member.

[0012] In one embodiment of the present application, the locking member is provided with a second guide surface.

[0013] The technical effects achieved by the technical scheme are as follows: the second guide surface includes at least two times of guiding effects: in the process of the fitting protrusion being fitted into the fitting opening, the side of the fitting opening close to the side wall of the upper fixing member is in contact with the second guide surface, thereby facilitating the fitting protrusion and the locking member at the end thereof to slide into the fitting opening; when the fitting protrusion extends to the other side of the fitting opening, the side of the fitting opening away from the side wall of the upper fixing member is in contact with the second guide surface, thereby facilitating the locking member to slide into the other side of the fitting opening.

[0014] In one embodiment of the present application, the foot pad is provided with a supporting end, which is located at the top of the foot pad; wherein the supporting end is in abutment with the top of the upper fixing member; or the upper fixing member is provided with a sleeving hole, the supporting end extends out of the sleeving hole, and the supporting end cooperates with the sleeving hole.

[0015] The technical effects achieved by the technical scheme are as follows: the supporting end of the foot pad can be fixed relative to the upper fixing member, so that the foot pad cannot slide.

[0016] In one embodiment of the present application, the upper fixing member has elasticity, and the upper fixing member is provided with a deformation opening, which is located at the bottom surface of the upper fixing member.

[0017] The technical effects achieved by the technical scheme are as follows: in the process of cooperation between the upper fixing member and the lower fixing member, the fitting protrusion on the bottom surface of the upper fixing member first contacts the outer wall of the lower fixing member, so that the side wall of the upper fixing member deforms outward, until the fitting protrusion cooperates with the fitting opening, the side wall of the upper fixing member rebounds, and the deformation opening provides a deformation allowance for the side wall of the upper fixing member to deform; on the contrary, when the fitting protrusion on the bottom surface of the upper fixing member deforms outward, the side wall of the upper fixing member deforms inward, and the deformation opening also provides a deformation allowance for the upper fixing member.

[0018] In one embodiment of the present application, the top of the upper fixing member is conical.

[0019] The technical effects achieved by adopting this technical solution are as follows: The installation environment of the compressor is full of pipes, such as return pipes, and the temperature is low. When the air conditioner is running, condensation will be generated. The top of the upper fixing part is designed to be conical, which can guide the condensation to flow to the outside of the lower fixing part, so as to prevent the condensation from dripping onto the foot pads and causing wear on the foot pads, or causing the bolts of the compressor to be corroded.

[0020] On the other hand, the present invention also provides a compressor, the compressor comprising: a plurality of support legs; a compressor foot pad fixing device as described in any of the above embodiments; wherein the upper fixing member is disposed on the support legs.

[0021] The technical effect achieved by adopting this technical solution is that the upper fixing parts on the multiple support legs of the compressor can simultaneously cooperate with the corresponding support legs, and the compressor can be quickly installed based on the quick engagement of the upper fixing parts and the lower fixing parts.

[0022] In one embodiment of the present invention, the compressor further includes a fixing column, and the foot pad is sleeved on the fixing column.

[0023] The technical effect achieved by adopting this technical solution is that the foot pad is positioned by the fixed column, so the foot pad can stably support the body of the compressor.

[0024] In one embodiment of the present invention, the fixing post abuts against the top of the upper fixing member; or, the upper fixing member is provided with a sleeve hole, the sleeve hole is located at the top of the upper fixing member, and the fixing post passes through the sleeve hole.

[0025] The technical effect achieved by adopting this technical solution is that after the fixing post abuts against the upper fixing member, the upper fixing member will not slide; or, after the fixing post passes through the sleeve hole, the fixing post positions the upper fixing member through the sleeve hole.

[0026] On the other hand, the present invention provides an air conditioner including the compressor foot pad fixing device or compressor provided in any of the above embodiments.

[0027] The technical effect achieved by adopting this technical solution is as follows: the compressor, through the upper fixing member connected to the support leg, cooperates with the foot pad set on any mounting plate of the air conditioner and is fastened with the lower fixing member, which facilitates the fixing of the foot pad and improves the assembly efficiency of the air conditioner.

[0028] In summary, the above embodiments of this application can have one or more of the following advantages or beneficial effects: i) The compressor can be quickly fixed to the mounting plate through the cooperation of the upper fixing member and the lower fixing member, improving assembly efficiency. At the same time, the upper fixing member is sleeved with the foot pad, realizing the fixation of the foot pad; ii) The upper fixing member is provided on the support leg of the compressor, for example, it is an integral structure, and multiple support legs can be fixed at the same time, improving assembly efficiency. Moreover, no assembly is required between the upper fixing member and the support leg, further improving assembly efficiency; iii) The upper fixing member is provided with the deformation opening and is elastic, and can quickly cooperate with the lower fixing member through deformation; iv) The connection method of the cooperation opening and the cooperation protrusion makes the upper fixing member and the lower fixing member stably connected, and the upper fixing member will not move in any direction; v) The upper fixing member can prevent condensate from entering the upper fixing member, avoiding damage to the foot pad or corrosion of the bolts. The top of the upper fixing member is conical, which can further guide the condensate to flow to the outside of the lower fixing member. Attached Figure Description

Detailed Implementation

[0040] The purpose of this invention is to provide a compressor and an air conditioner, wherein the compressor's support legs are provided with an upper fixing member, which is sleeved on the foot pad and fastened to the lower fixing member, thereby quickly fixing the foot pad and completing the installation of the compressor.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] [First Embodiment]

[0043] See Figure 1 The first embodiment of the present invention provides a compressor 100, which is mounted on a mounting plate 210. The compressor 100 is provided with a compressor foot pad fixing device 10 and a plurality of support legs 110. The compressor foot pad fixing device 10 further includes, for example, a foot pad 120, an upper fixing member 130, and a lower fixing member 140. The upper fixing member 130 is disposed on the support leg 110 and is sleeved on the foot pad 120, with the top surface of the upper fixing member 130 engaging with the foot pad 120. The lower fixing member 140 is disposed between the upper fixing member 130 and the mounting plate 210 and is fixed to the mounting plate 210.

[0044] In this embodiment, after the upper fixing member 130 is sleeved with the foot pad 120, the foot pad 120 can support the support leg 110 of the compressor 100; after the lower fixing member 140 is fixed to the mounting plate 210 by spot welding, plugging or bolts, the upper fixing member 130 and the lower fixing member 140 are connected, which can fix the position of the upper fixing member 130 and prevent the upper fixing member 130 from moving, thereby realizing the quick fixation of the foot pad 120.

[0045] In one specific embodiment, the compressor 100 may further include, for example, a fixing post 150, with a foot pad 120 sleeved on the fixing post 150, and the fixing post 150 disposed on the mounting plate 210. For example, the fixing post 150 is inserted into the mounting plate 210, or connected to the mounting plate 210 by threads, thereby fixing it to the mounting plate 210 and positioning the foot pad 120 so that the foot pad 120 can always be in a designated position to support the support legs 110 of the compressor 100. The fixing post 150 may be, for example, a bolt.

[0046] Preferred, see Figures 2-4 This is a schematic diagram of the first structure of the upper fixing member 130. In this case, the fixing post 150 abuts against the top of the upper fixing member 130. For example, the top of the upper fixing member 130 is a closed plate-like structure, and the fixing post 150 abuts against the inner side of the top of the upper fixing member 130, thereby realizing the connection between the upper fixing member 130 and the fixing post 150.

[0047] Furthermore, the center of the top of the upper fixing member 130 may protrude upwards to prevent condensation in the installation environment of the compressor 100 from entering the upper fixing member 130. For example, the top of the upper fixing member 130 may be conical, such as a cone or pyramid, thereby further guiding condensation along the top surface of the upper fixing member 130 to the outside of the lower fixing member 140, preventing damage to the foot pad 120 or corrosion of the bolts.

[0048] Preferred, see Figure 2 , Figures 5-6 This is a schematic diagram of a second structure for the upper fixing member 130. In this case, the upper fixing member 130 is provided with a sleeve hole 131, which is located at the top of the upper fixing member 130, and the fixing post 150 passes through the sleeve hole 131. The diameter of the fixing post 150 matches the diameter of the sleeve hole 131 to prevent the upper fixing member 130 from shifting relative to the fixing post 150; or, the diameter of the fixing post 150 is slightly smaller than the sleeve hole 131, but the diameter of the top surface of the foot pad 120 is slightly larger than the diameter of the sleeve hole 131, so that the foot pad 120 and the upper fixing member 130 have overlapping portions, and the foot pad 120 can support the upper fixing member 130.

[0049] In one specific embodiment, the foot pad 120 is provided with a support end 121, which is located at the top of the foot pad 120, so as to connect the foot pad 120 with the upper fixing member 130, thereby stably supporting the support leg 110 of the compressor 100.

[0050] Preferred, see Figures 3-4The support end 121 abuts against the top of the upper fixing member 130. Based on the slight deformation of the upper fixing member 130, the support end 121 causes the upper fixing member 130 to deform during the process of supporting the upper fixing member 130. The support end 121 obtains elastic force in multiple directions, so that the positions of the upper fixing member 130 and the foot pad 120 are relatively fixed.

[0051] At this time, the upper fixing member 130 can be provided with a socket hole 131, that is, the fixing post 150 extends out of the upper fixing member 130; of course, the top of the upper fixing member 130 can also be in a closed state, that is, the fixing post 150 abuts against the top surface of the upper fixing member 130.

[0052] Preferred, see Figure 2 , Figures 5-6 Based on the upper fixing member 130 having a sleeve hole 131, the support end 121 of the foot pad 120 can also extend out of the sleeve hole 131 together with the fixing post 150, and the support end 121 cooperates with the sleeve hole 131 to realize the fixing of the upper fixing member 130 and the foot pad 120.

[0053] For example, the foot pad 120 includes a support end 121 and a foot pad body 122, and a mounting groove 123 located between the support end 121 and the foot pad body 122, with the socket hole 131 nested within the mounting groove 123. In this case, the support end 121 limits the top of the upper fixing member 130, preventing the upper fixing member 130 from easily detaching from the upper end of the foot pad 120, thus improving the connection stability of the compressor foot pad fixing device 10.

[0054] Preferably, the foot pad 120 is a columnar structure with a varying diameter. For example, the diameter of the support end 121 is larger than the diameter of the socket 131, so that the support end 121 can pass through the socket 131 with slight deformation, and the foot pad 120 can be prevented from sliding out of the socket 131.

[0055] Preferably, the foot pad 120 includes a first guide surface 124 located at the support end 121. For example, the first guide surface 124 surrounds the top of the support end 121, and the diameter of the support end 121 gradually decreases in the direction away from the foot pad body 122, thereby guiding the socket hole 131. After the socket hole 131 is fitted onto the support end 121, the socket hole 131 slides downward along the first guide surface 124 due to the gravity of the compressor 100. At this time, the socket hole 131 slightly deforms and enlarges, and finally slides into the mounting groove 123. Therefore, the mating process between the upper fixing member 130 and the foot pad 120 is more convenient.

[0056] Preferably, the diameter of the foot pad body 122 is larger than the diameter of the support end 121, so that the foot pad 120 has a good support effect on the upper fixing member 130.

[0057] In one specific embodiment, see Figure 1 The upper fixing member 130 and the support leg 110 are integral structures, for example, welded together. In this case, the upper fixing member 130 and the support leg 110 do not need to be fixed by fasteners, thereby improving the assembly efficiency of the compressor 100.

[0058] Based on the compressor 100 having multiple support legs 110, the compressor 100 also has multiple upper fixing parts 130 and lower fixing parts 140. After the multiple upper fixing parts 130 are aligned with the corresponding lower fixing parts 140, the multiple upper fixing parts 130 and the corresponding lower fixing parts 140 can cooperate simultaneously by the weight of the compressor 100, thereby further improving the assembly efficiency of the compressor 100.

[0059] In one specific embodiment, see Figure 2 and Figures 7-8 The upper fixing member 130, for example, has at least one mating protrusion 132 located on the side wall of the upper fixing member 130; the lower fixing member 140, for example, has at least one mating opening 141 into which the mating protrusion 132 is inserted. Both the side wall of the upper fixing member 130 and the lower fixing member 140 are annular columnar structures. The side wall of the upper fixing member 130 can fit inside or outside the lower fixing member 140.

[0060] For example, the mating protrusion 132 can extend radially outward along the side wall of the upper fixing member 130. In this case, the side wall of the upper fixing member 130 is located inside the lower fixing member 140, and the mating protrusion 132 engages outward with the mating opening 141 of the lower fixing member 140. Alternatively, the mating protrusion 132 can extend radially inward along the side wall of the upper fixing member 130. In this case, the side wall of the upper fixing member 130 is located outside the lower fixing member 140, and the mating protrusion 132 engages inward with the mating opening 141 of the lower fixing member 140.

[0061] Preferably, the mating protrusion 132 is, for example, a horizontal protrusion block, and the mating opening 141 is, for example, a horizontal groove, thereby increasing the area of ​​the upper and lower surfaces of the mating protrusion 132 overlapping with the mating opening 141, making the connection between the mating opening 141 and the mating protrusion 132 more stable.

[0062] In one specific embodiment, the upper fixing member 130 is provided with a plurality of mating protrusions 132, which surround the sidewall of the upper fixing member 130; correspondingly, the lower fixing member 140 is provided with a plurality of mating openings 141 at corresponding positions. For example, the upper fixing member 130 includes two mating protrusions 132 arranged opposite each other, and the lower fixing member 140 includes two mating openings 141 arranged opposite each other, thereby improving the supporting effect of the lower fixing member 140 on the upper fixing member 130 and preventing the upper fixing member 130 or the lower fixing member 140 from tilting to either side.

[0063] Of course, the number of vertical beams that cooperate with the protrusions 132 and the openings 141 can be 3, 4, 5, 6, etc., and there is no limitation here. Preferably, the protrusions 132 are evenly distributed on the side wall of the upper fixing member 130, and correspondingly, the openings 141 are evenly distributed on the side of the lower fixing member 140, so that the connection between the upper fixing member 130 and the lower fixing member 140 is more stable.

[0064] In one specific embodiment, the mating protrusion 132 passes through the mating opening 141 to the side of the mating opening 141 away from the sidewall of the upper fixing member 130; the mating protrusion 132 is provided with a locking member 133, which is located on the other side. For example, when the mating protrusion 132 is located on the inner side of the sidewall of the upper fixing member 130, the mating protrusion 132 passes through the mating opening 141 to the inner side of the lower fixing member 140, thereby preventing the mating protrusion 132 from disengaging outward from the mating opening 141; when the mating protrusion 132 is located on the outer side of the sidewall of the upper fixing member 130, the mating protrusion 132 passes through the mating opening 141 to the outer side of the lower fixing member 140, thereby preventing the mating protrusion 132 from disengaging inward from the mating opening 141.

[0065] The locking element 133 can be located on the upper surface of the mating protrusion 132 or on the lower surface of the mating protrusion 132.

[0066] Preferably, the locking member 133 is provided with a second guide surface 134, which guides the mating protrusion 132 as it enters the mating opening 141. The slope of the second guide surface 134 is, for example, 30° to 60°.

[0067] Furthermore, the second guide surface 134 is located on the side of the locking member 133 facing the mating opening 141. For example, the locking member 133 is located on the upper surface of the mating protrusion 132. Before the mating protrusion 132 enters the mating opening 141, the second guide surface 134 contacts one side of the top surface of the mating opening 141, thereby guiding the mating protrusion 132 into the mating opening 141. When the mating protrusion 132 passes through the mating opening 141, the second guide surface 134 guides the locking member 133 to slide upward, so that the mating protrusion 132 and the mating opening 141 are fully engaged.

[0068] In one specific embodiment, see Figure 3 The upper fastener 130 is elastic; for example, the top and side walls of the upper fastener 130 can be made of stainless steel that has undergone spring heat treatment. Of course, the upper fastener 130 can also be made of other elastic materials, which are not limited here.

[0069] Preferably, the upper fixing member 130 is provided with a deformation opening 135, which is located on the bottom surface of the upper fixing member 130. For example, the deformation opening 135 and the mating protrusion 132 are spaced apart. For example, based on the upper fixing member 130 having two opposing mating protrusions 132, the deformation opening 135 is located between the two mating protrusions 132, and the two deformation openings 135 are arranged opposite each other.

[0070] Furthermore, the deformation opening 135 is, for example, a triangular structure with two sides. When the upper fixing member 130 is fitted onto the outside of the lower fixing member 140, the included angle between the two sides increases due to the deformation of the upper fixing member 130 during the engagement of the upper fixing member 130 and the lower fixing member 140; when the upper fixing member 130 is fitted onto the inside of the lower fixing member 140, the included angle between the two sides decreases due to the deformation of the upper fixing member 130 during the engagement of the upper fixing member 130 and the lower fixing member 140.

[0071] In one specific embodiment, the upper fixing member 130 can be cylindrical or prism in shape, without limitation. The lower fixing member 140 has the same shape as the upper fixing member 130.

[0072] [Second Embodiment]

For example, the compressor 100 is mounted on the mounting plate 210 of the air conditioner 200. The mounting plate 210 is, for example, the chassis of the air conditioner.

[0074] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
