[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] It is understandable that, referring to Figures 1 to 6 The compression device of the first embodiment of the present invention includes a moving mechanism 100 and a compressor 200. The moving mechanism 100 includes a base plate 110, a connecting block 120 and a driving member 130. The connecting block 120 is slidably connected to the base plate 110. The driving member 130 is used to drive the connecting block 120 to slide on the base plate 110. The compressor 200 is provided with a connecting portion 210. The connecting block 120 is provided with a slot 121. The connecting portion 210 is inserted into the slot 121. The slot 121 is provided with a connecting portion 210. 1 gradually decreases in a direction away from the connecting portion 210. The shape of the connecting portion 210 matches the shape of the slot 121. A groove 211 is formed on the side wall of the connecting portion 210. The connecting block 120 is provided with a screw 141 and a pressing block 142. The screw 141 is threadedly connected to the connecting block 120. The pressing block 142 is slidably connected to the connecting block 120. The screw 141 can drive the pressing block 142 to approach the connecting portion 210 so that the pressing block 142 can extend into the groove 211.

[0032] The connecting block 120 is slidably connected to the bottom plate 110. The connecting block 120 is provided with a slot 121. The compressor 200 is provided with a connecting portion 210. The connecting portion 210 is inserted into the slot 121. By setting the cross-sectional area of the slot 121 to gradually decrease in the direction away from the connecting portion 210, the connecting portion 210 can gradually abut against the side wall of the slot 121, thereby making the connecting portion 210 stable in the slot 121 and preventing the connecting portion 210 from shaking in the slot 121, thereby making the compressor 200 stable in the connecting portion 210. The block 120 is provided with a groove 211 on the side wall of the connecting portion 210. The screw 141 is threadedly connected to the connecting block 120. By rotating the screw 141, the screw 141 can be screwed into the connecting block 120, so that the screw 141 can drive the pressure block 142 to slide on the connecting block 120, thereby allowing the pressure block 142 to extend into the groove 211, thereby locking the connecting portion 210 in the slot 121, so that the compressor 200 can be stably mounted on the connecting block 120, thereby improving the installation convenience of the compressor 200. By setting the cross-section of the slot 121 to gradually decrease in the direction away from the connecting portion 210 and allowing the pressure block 142 to extend into the groove 211, the installation and removal of the compressor 200 can be facilitated, improving the installation efficiency of the compressor 200, and ensuring that the compressor 200 is stably mounted on the connecting block 120, thereby improving the positional stability of the compressor 200.

[0033] It should be noted that the shape of the slot 121 is rectangular. By setting at least one side wall of the slot 121 to be inclined, when the connecting part 210 is inserted into the slot 121, the wall surface of the connecting part 210 can gradually abut against the side wall of the slot 121, so that the connecting part 210 can fit tightly with the side wall of the slot 121, increasing the friction between the connecting part 210 and the side wall of the slot 121, reducing the possibility of the connecting part 210 slipping out of the slot 121, and improving the connection stability between the compressor 200 and the connecting block 120.

[0034] It is understandable that, referring to Figure 5 and Figure 6The connecting block 120 is provided with a fixed plate 143 and a cushion block 144. The screw 141 is threadedly connected to the fixed plate 143. The connecting block 120 is provided with a slide groove 122. The slide groove 122 is connected to the slot 121. The pressing block 142 and the cushion block 144 are both slidably connected to the slide groove 122. One end of the cushion block 144 is connected to the screw 141, and the other end of the cushion block 144 is connected to the pressing block 142. The fixing plate 143 is fixedly connected to the connecting block 120. The connecting block 120 is provided with a slide groove 122. The pad 144 is slidably set in the slide groove 122. The screw 141 is threadedly connected to the fixing plate 143. The screw 141 is driven to rotate so that the screw 141 can be screwed into the fixing plate 143, so that the screw 141 can drive the pad 144 to slide in the slide groove 122, so that the pad 144 can drive the pressure block 142 to move from the slide groove 122 to the slot 121, so that the pressure block 142 can extend into the groove 211, so that the pressure block 142 can lock the position of the connecting part 210, and thus the compressor 200 can be stabilized on the connecting block 120.

[0035] Among them, by setting the pressing block 142 and the cushion block 144 to slide in the sliding groove 122, the movement stability of the pressing block 142 and the cushion block 144 can be improved, the pressing block 142 can be prevented from being stuck on the connecting block 120, and the movement smoothness of the pressing block 142 can be improved.

[0036] It should be noted that the fixing plate 143 may be fixedly connected to the connecting block 120 by means of fasteners, welding, gluing, etc., so as to improve the position stability of the fixing plate 143 .

[0037] Specifically, refer to Figure 5 and Figure 6 The screw rod 141 is threadedly connected to a nut 145, which abuts against the side of the fixing plate 143 facing away from the cushion block 144. The nut 145 is threadedly connected to the screw rod 141. By setting the nut 145 to abut against the side of the fixing plate 143 facing away from the cushion block 144, the nut 145 can lock the screw rod 141 on the fixing plate 143, thereby reducing the position of the screw rod 141. The position of the pressure block 142 is stabilized, and the connection portion 210 can be stabilized in the slot 121.

[0038] It should be noted that the drive nut 145 rotates on the screw 141 so that the nut 145 can abut against the fixing plate 143, thereby locking the screw 141 on the fixing plate 143, reducing the possibility of the screw 141 loosening, improving the position stability of the screw 141, and enabling the pressure block 142 to be stabilized in the groove 211, reducing the possibility of the connecting part 210 slipping out of the slot 121, and improving the reliability of the compression device.

[0039] Specifically, refer to Figure 5 and Figure 6The pressing block 142 is provided with a retaining ring 146. An elastic member 147 is provided between the retaining ring 146 and the cushion block 144. The elastic member 147 is used to drive the retaining ring 146 to move in a direction away from the cushion block 144. The retaining ring 146 is provided on the pressing block 142. One end of the elastic member 147 abuts against the retaining ring 146, and the other end abuts against the cushion block 144. By providing the elastic member 147, the retaining ring 146 can be driven to move in a direction away from the cushion block 144, so that the pressing block 142 can abut against the groove 211, thereby improving the position stability of the pressing block 142, preventing the pressing block 142 from escaping from the groove 211, improving the installation firmness of the compressor 200, and improving the reliability of the compression device.

[0040] It should be noted that the elastic member 147 can be a plurality of disc springs stacked together, or a compression spring or an elastic rubber member, etc., which will not be described in detail here.

[0041] Specifically, refer to Figure 5 and Figure 6 The retaining ring 146 is provided with a guide post 148, and the cushion block 144 is provided with a guide groove 149. The guide post 148 is slidably connected to the guide groove 149, and the elastic member 147 is sleeved in the guide post 148. The guide post 148 is provided on the retaining ring 146, and the cushion block 144 is provided with a guide groove 149. By providing the guide post 148 to be slidably connected to the guide groove 149, the guide post 148 can slide along the axial direction of the guide groove 149, thereby improving the movement stability of the pressure block 142, allowing the pressure block 142 to slide smoothly in the slide groove 122, and preventing the pressure block 142 from getting stuck on the side wall of the slide groove 122.

[0042] In addition, the elastic member 147 is sleeved in the guide column 148, which can stabilize the position of the elastic member 147, reduce the position shaking of the elastic member 147, enable the cushion block 144 and the retaining ring 146 to be balanced in force, and improve the movement stability of the pressure block 142.

[0043] It is understandable that, referring to Figure 5 and Figure 6 The pressing block 142 is spherical in shape, and the groove 211 is conical in shape. The pressing block 142 can abut against the wall of the groove 211. The pressing block 142 is spherical in shape, and the groove 211 is arc-shaped. By setting the pressing block 142 to abut against the wall of the groove 211, the pressing block 142 can guide the movement of the connecting portion 210, thereby positioning the connecting portion 210 in the slot 121, reducing the positional shaking of the connecting portion 210, and enabling the connecting portion 210 to be locked in the slot 121, thereby improving the positional stability of the connecting portion 210.

[0044] In addition, when the connecting portion 210 is removed from the slot 121 , the pressing block 142 can slide on the wall surface of the groove 211 , thereby guiding the pressing block 142 to smoothly escape from the groove 211 , thereby improving the convenience of disassembling the compressor 200 .

[0045] It is understandable that, referring to Figure 2 and Figure 3 The driving member 130 includes a slide rail 131, a slider 132, a screw rod 133 and a motor 134. The slide rail 131 is fixedly connected to the base plate 110, the slider 132 is slidably connected to the slide rail 131, the connecting block 120 is fixedly connected to the slider 132, and the connecting block 120 is provided with a movable block 123.

The slide rail 131 is fixedly connected to the base plate 110, the slider 132 is slidably connected to the slide rail 131, and the connecting block 120 is fixedly connected to the slider 132 so that the connecting block 120 can move along the length direction of the slide rail 131. The connecting block 120 is provided with a movable block 123, and the movable block 123 is threadedly connected to the screw rod 133. The screw rod 133 is driven to rotate by the motor 134 so that the screw rod 133 can drive the movable block 123 to move along the axial direction of the screw rod 133, thereby driving the connecting block 120 to slide along the length direction of the slide rail 131, realizing automatic compression of the compressor 200 and improving the convenience of use of the compression device.
