For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and can also be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0059] As Figures 1 to 3 Shown, in some embodiments of the present invention, the automatic bedding distribution device 100 includes a cabinet 110, a plurality of bedding box units 120, at least one vertical guide rail 130, at least one horizontal guide rail 140, a first vertical driving device 150, a second vertical driving device 160, a top driving device 170, and a bottom driving device 180.

[0060] Although not explicitly shown in the figure, the cabinet body 110 defines a top space, a bottom space, a first vertical space, and a second vertical space located between the top space and the bottom space. The top space, the bottom space, the first vertical space, and the second vertical space are used to accommodate a plurality of bedding box units 120.

[0061] As Figures 2 to 3 shown, the cabinet body 110 includes a first cabinet body 111, a second cabinet body 112, a cabinet body cover 113, and a gear 114. The first cabinet body 111 and the second cabinet body 112 are fixedly connected to define a top space, a bottom space, a first vertical space, and a second vertical space. Among them, a cabinet opening 1111 is provided on the front side of the first cabinet body 111, and the cabinet opening 1111 is used for medical staff to pick up and place bedding. A pushing structure 1112 is provided on the inner side of the front side plate of the first cabinet body 111, and the pushing structure 1112 is used to push the second stop structure 1221 on the upper cover 122 of the bedding box unit 120 in the horizontal direction. Preferably, the bottom surface of the pushing structure 1112 near one end thereof slopes upward, so that the pushing structure 1112 pushes the second stop structure 1221 to swing in the horizontal direction through the inclined bottom surface, specifically, pushes the second stop structure 1221 to swing left or right. A gear shaft 1113 is further provided on the first cabinet body 111, and the gear shaft 1113 is used to install the gear 114.

[0062] As Figure 3 shown, the cabinet body cover 113 is slidably connected to the first cabinet body 111 in a vertically movable manner, and the cabinet body cover 113 is used to shield the cabinet opening 1111. Preferably, the cabinet body cover 113 opens the cabinet opening 1111 by sliding upward and shields the cabinet opening 1111 by sliding downward. Further, a first vertical rack 1131 and a first stop structure 1132 are provided on the inner side of the cabinet body cover 113. The first vertical rack 1131 meshes with the gear 114 (as Figures 11 to 15 shown) so that the cabinet body cover 113 is driven by the rotating gear 114 to move upward, thereby opening the cabinet opening 1111. The first stop structure 1132 interferes with the second stop structure 1221 on the upper cover 122 of the bedding box unit 120 in the vertical direction, so that the upward moving cabinet body cover 113 drives the cover 122 to move upward through the interference between the first stop structure 1132 and the second stop structure 1221, thereby opening the box opening 12101 of the bedding box unit 120, and further enabling the bedding automatic dispensing device 100 to open the cabinet opening 1111 and the box opening 12101 simultaneously.

[0063] Although not shown in the figures, in some embodiments of the present invention, the opened cabinet cover 113 can fall back to the position covering the cabinet opening 1111 by its own gravity. Alternatively, those skilled in the art can also, as needed, provide a first reset member between the cabinet cover 113 and the first cabinet body 111 to enable the cabinet cover 113 to fall back to the position covering the cabinet opening 1111 through the first reset member. The first reset member can be any feasible member, such as a compression spring, a tension spring, etc.

[0064] As Figure 2 and Figure 3 shown, a plurality of bedding box units 120 are distributed in at least one of the top space, the bottom space, the first vertical space, and the second vertical space, and each bedding box unit 120 can move to any one of the top space, the bottom space, the first vertical space, and the second vertical space. Preferably, when medical staff replace clean bedding, the bedding box units 120 move in sequence and in a cycle in the order of the top space, the first vertical space, the bottom space, and the second vertical space. Further preferably, the first vertical space and the second vertical space respectively accommodate a plurality of bedding box units 120. And, at the same time, only one of the top space and the bottom space accommodates one bedding box unit 120, so that while the bedding box units 120 can move in a cycle within the four spaces, the automatic bedding dispensing device 100 can accommodate the most bedding box units 120 and store more bedding.

[0065] As Figure 4 shown, the bedding box unit 120 includes a box body 121, a box cover 122, a lead screw nut 123, and a fixed flange 124. Among them, a box opening 12101 corresponding to the cabinet opening 1111 is provided on the front side of the box body 121, and a slider 1211 is respectively provided on the four edges of the box body 121 in the horizontal direction, so that the bedding box unit 120 is slidably connected to the vertical guide rail 130 through the slider 1211. Optionally, the slider 1211 is at the same height as the box body 121.

[0066] As Figures 4 to 7 shown, a second vertical rack 1212 is further provided on the front side of the box body 121, and the second vertical rack 1212 meshes with the gear 114 on the cabinet body 110. Preferably, the second vertical rack 1212 is provided on a slider 1211 on the front side of the box body 121.

[0067] Continuing to refer to Figure 4 , non-circular cross-section fixing columns 1213 are respectively provided on the left and right sides of the box body 121, and the fixing columns 1213 are used for installing the lead screw nut 123.

[0068] Continuing to refer to Figure 4, the lid 122 is used to cover the box opening 12101, and the lid 122 is slidably connected to the box body 121 in a vertically movable manner. Preferably, the lid 122 opens the box opening 12101 by sliding forward and upward to prevent interference with the upper bedding box unit 120 when the lid 122 is opened.

[0069] Although not shown in the figures, in some embodiments of the present invention, the opened lid 122 can fall back to the position covering the box opening 12101 by its own gravity. Alternatively, those skilled in the art can also, as needed, provide a second reset member between the lid 122 and the box body 121 to enable the lid 122 to fall back to the position covering the box opening 12101 through this second reset member. The second reset member can be any feasible member, such as a compression spring, a tension spring, etc.

[0070] As Figure 4 and Figure 8 shown, a second stop structure 1221 is provided on the outer side of the lid 122. The second stop structure 1221 interferes with the first stop structure 1132 in the vertical direction under normal conditions, and the second stop structure 1221 can swing left and right in the horizontal direction.

[0071] In order to enable the second stop structure 1221 to swing left and right in the horizontal direction, the second stop structure 1221 can be a structure made of an elastic material, such as a plastic rod, a metal plate, etc. Alternatively, the second stop structure 1221 is pivotally connected to the lid 122, and a torsion spring is provided between the second stop structure 1221 and the lid 122. The torsion spring is used to restore and maintain the second stop structure 1221 in the initial position. When the second stop structure 1221 is in this initial position, the second stop structure 1221 interferes with the first stop structure 1132 in the vertical direction.

[0072] Continuing to refer to Figure 4 , a long hole is provided on the lead screw nut 123, and the lead screw nut 123 is inserted together with the fixed column 1213 through this long hole. Among them, the length of the long hole is greater than the length of the fixed column 1213 in the vertical direction, so that the lead screw nut 123 can float relative to the box body 121 in the vertical direction. Further, a vertical first sink 1231 is provided at the front end of the lead screw nut 123, a first thread (not shown in the figure) is provided on the side wall of the first sink 1231, a vertical second sink 1232 is provided at the rear end of the lead screw nut 123, and a second thread (not shown in the figure) is provided on the side wall of the second sink 1232. The lead screw nut 123 is drivingly connected to the first vertical driving device 150 through the first thread in the first sink 1231, and is drivingly connected to the second vertical driving device 160 through the second thread in the second sink 1232.

[0073] Preferably, the maximum floating stroke of the lead screw nut 123 relative to the box body 121 is equal to the pitches of the first lead screw 152 and the second lead screw 162.

[0074] Alternatively, those skilled in the art can also, according to needs, make the maximum floating stroke greater than or less than the pitches of the first lead screw 152 and the second lead screw 162. For example, make the maximum floating stroke half of the pitch.

[0075] Continue to refer to Figure 4 , the fixing flange 124 is used to fix the lead screw nut 123 to the box body 121 in the horizontal direction. Specifically, through holes are provided on the fixing flange 124, threaded holes are provided on the fixing column 1213. After the screw / bolt passes through the through holes on the fixing flange 124, it is tightened into the threaded holes on the fixing column 1213, so as to tighten the fixing flange 124 and the fixing column 1213 together.

[0076] Continue to refer to Figure 4 , a counterbore is further provided at one end of the lead screw nut 123 close to the fixing flange 124. The fixing flange 124 includes a small-diameter section inserted into the long slot of the lead screw nut 123 and a large-diameter section embedded in the counterbore.

[0077] As Figure 2 , Figure 3 , Figure 5 and Figure 9 shown, in the preferred embodiments of some embodiments of the present invention, there are two vertical guide rails 130. The two vertical guide rails 130 are arranged between the first vertical space and the second vertical space, and the vertical guide rails 130 are respectively slidably connected to the bedding box units 120 in the first vertical space and the second vertical space, so that the vertical guide rails 130 guide the bedding box units 120 to move in the vertical direction. Further, the two vertical guide rails 130 are respectively located on the left and right sides of the bedding box unit 120.

[0078] As Figure 2 and Figure 9 shown, the first chute 131 and the second chute 132 are provided on the vertical guide rail 130. The first chute 131 matches the slider 1211 at the rear side of the bedding box unit 120, and the second chute 132 matches the slider 1211 at the front side of the bedding box unit 120. In other words, for the bedding box unit 120 located in the first vertical space, the slider 1211 at its rear side is embedded in the first chute 131. For the bedding box unit 120 located in the second vertical space, the slider 1211 at its front side is embedded in the second chute 132.

[0079] From Figure 2 and Figure 9It can be seen that the contour of the end faces of the first chute 131 and the second chute 132 is approximately three-quarters of an oval. Correspondingly, the part of the slider 1211 embedded in the first chute 131 or the second chute 132 is also approximately three-quarters of an oval. Therefore, the first chute 131 and the second chute 132 can prevent the slider 1211 therein from rotating and do not allow the slider 1211 therein to move in the horizontal direction.

[0080] In addition, those skilled in the art can also set the contour of the end faces of the first chute 131 and the second chute 132 to any other feasible structure according to needs, such as a rectangle, a semi-circle, etc., so that the bedding box unit 120 will not move or swing in the left-right direction under the combined restriction of the first chute 131 and the second chute 132.

[0081] As Figure 2 、 Figure 3 、 Figure 5 and Figure 10 shown, in the preferred embodiments of some embodiments of the present invention, there are two transverse guide rails 140, and both of these two transverse guide rails 140 are arranged in the top space of the cabinet 110. The transverse guide rails 140 are used to carry the lead screw nut 123 to support the movement of the bedding box unit 120 in the top space. In other words, when the bedding box unit 120 is in the top space, the lead screw nut 123 of the bedding box unit 120 is located above the transverse guide rail 140 and is in sliding contact with the transverse guide rail 140.

[0082] Furthermore, if the lead screw nut 123 located in the first vertical space is denoted as the first lead screw nut, the lead screw nut 123 located in the second vertical space is denoted as the second lead screw nut, and the distance between the second sink 1232 of the first lead screw nut and the first sink 1231 of the second lead screw nut is denoted as the sink spacing, then the length of the transverse guide rail 140 is equal to this sink spacing.

[0083] As Figure 5 and Figure 10 shown, both ends of the transverse guide rail 140 are arc-shaped so that both ends of the transverse guide rail 140 match the side walls of the first sink 1231 and the second sink 1232 in the horizontal direction. In other words, the projections of both ends of the transverse guide rail 140, the side walls of the first sink 1231, and the side walls of the second sink 1232 on the horizontal plane almost coincide.

[0084] Furthermore, the distance between the bottom end of the horizontal guide rail 140 and the top end of the vertical guide rail 130 is less than the minimum distance between the top end of the lead screw nut 123 and the bottom end of the slider 1211. So that during the process of the bedding box unit 120 rising from the first vertical space or the second vertical space to the top space, and before the slider 1211 disengages from the vertical guide rail 130, the lead screw nut 123 matches with one end of the horizontal guide rail 140, so that the lead screw nut 123 and the horizontal guide rail 140 are slidably matched in the vertical direction to guide the bedding box unit 120 to continue rising.

[0085] Meanwhile, the distance between the top end of the horizontal guide rail 140 and the top end of the vertical guide rail 130 is greater than the maximum distance between the bottom end of the lead screw nut 123 and the bottom end of the slider 1211, to prevent the bottom end of the bedding box unit 120 from interfering with the vertical guide rail 130 in the horizontal direction when its lead screw nut 123 is located on the horizontal guide rail 140.

[0086] As Figure 2 、 Figure 3 、 Figures 5 to 8 shown, the first vertical driving device 150 includes a first motor 151 and a first lead screw 152. The first motor 151 is fixedly installed on the top of the cabinet 110, and one end of the first lead screw 152 is drivingly connected to the rotating shaft of the first motor 151. The first lead screw 152 extends into the first vertical space and is drivingly connected to the bedding box unit 120 in the first vertical space. Specifically, the first lead screw 152 meshes with the first thread corresponding to the first sunk groove 1231 of the lead screw nut 123 in the first vertical space. When the first motor 151 rotates, it drives the bedding box unit 120 to rise or fall through the meshing between the first lead screw 152 and the lead screw nut 123.

[0087] Those skilled in the art should understand that the first vertical driving device 150 of the present invention is not limited to Figure 2 、 Figure 3 、 Figures 5 to 8 the structure shown in, that is, not limited to the structure of two first motors 151 and two first lead screws 152. It can also be that one first motor 151 drives two first lead screws 152 at the same time. Or, only one first motor 151 and one first lead screw 152 are configured, and accordingly, the lead screw nut 123 on the bedding box unit 120 is also configured as one.

[0088] Continue to refer to Figure 2 、 Figure 3 、 Figures 5 to 8, the second vertical driving device 160 includes a second motor 161 and a second lead screw 162. The second motor 161 is fixedly installed on the top of the cabinet body 110, and one end of the second lead screw 162 is drivingly connected to the rotating shaft of the second motor 161. The second lead screw 162 extends into the second vertical space and is drivingly connected to the bedding box unit 120 in the second vertical space. Specifically, the second lead screw 162 is threadedly engaged with a second thread corresponding to a second sinking groove 1232 of a lead screw nut 123 in the second vertical space. When the second motor 161 rotates, the bedding box unit 120 is driven to rise or fall through the engagement between the second lead screw 162 and the lead screw nut 123.

[0089] Those skilled in the art should understand that the second vertical driving device 160 of the present invention is not limited to Figure 2 , Figure 3 , Figures 5 to 8 the structure shown in, that is, not limited to the structure of two second motors 161 and two second lead screws 162. It can also be a structure where one second motor 161 drives two second lead screws 162 simultaneously. Or, only one second motor 161 and one second lead screw 162 are configured, and accordingly, the lead screw nut 123 on the bedding box unit 120 is also configured as one.

[0090] Preferably, the height of the bottom end of the second lead screw 162 is higher than the height of the vertical guide rail 130, so that when the bedding box unit 120 enters the second vertical space from the bottom empty surface, the slider 1211 first slides into the second chute 132, and then the lead screw nut 123 is engaged with the second lead screw 162.

[0091] Similarly, those skilled in the art can also, according to needs, make the height of the bottom end of the first lead screw 152 higher than the height of the vertical guide rail 130.

[0092] Further preferably, both the first motor 151 and the second motor 161 are stepper motors to precisely control the bedding box unit 120 to stop at a position where its box opening 12101 is aligned with the cabinet opening 1111 of the cabinet body 110.

[0093] In addition, those skilled in the art can also, according to needs, set a Hall sensor on the cabinet body 110 and a magnet on the box body 121. When the bedding box unit 120 stops at a position where its box opening 12101 is aligned with the cabinet opening 1111 of the cabinet body 110, the Hall sensor on the cabinet body 110 is triggered, so that the bedding automatic dispensing device 100 determines that the current bedding box unit 120 has moved to a position where its box opening 12101 is aligned with the cabinet opening 1111 of the cabinet body 110, and controls the first motor 151 to stop rotating.

[0094] Such as Figure 2 , Figure 3 , Figure 7 andFigure 10 As shown, the top drive device 170 is installed on the rear side plate at the top of the cabinet body 110 to align the top drive device 170 with the top space. Further, the top drive device 170 includes a push rod (not marked in the figure) so that the top drive device 170 can push the bedding box unit 120 to move along the direction from the second vertical space to the first vertical space through the push rod. In other words, the push rod is used to push the bedding box unit 120 in the top space to move from Figure 7 the right side to the left side in

[0095] In some embodiments of the present invention, the top drive device 170 can be any feasible power device, such as a cylinder, an oil cylinder, an electric cylinder, etc.

[0096] As Figure 2 , Figure 3 , Figure 7 and Figure 8 shown, the bottom drive device 180 is arranged in the bottom space of the cabinet body 110. It is used to receive the bedding box unit 120 from the first vertical space, move the received bedding box unit 120 to the lower part of the second vertical space, and lift the bedding box unit 120 into the second vertical space. Specifically, the bottom drive device 180 includes a horizontal moving device 181 and a lifting platform 182. The horizontal moving device 181 is used to transport the bedding box unit 120 along the direction from the first vertical space to the second vertical space, and the lifting platform 182 is used to carry the bedding box unit 120 and lift and lower the bedding box unit 120.

[0097] Exemplarily, the horizontal moving device 181 includes a base, rollers installed on the base, and a driving device (such as a motor) for driving the rollers to rotate. The lifting platform 182 is a scissor-type lifting platform arranged above the base. Further, stop structures are respectively arranged on the four sides of the lifting platform 182 so that the lifting platform 182 can limit the horizontal movement of the bedding box unit 120 through the four stop structures.

[0098] Next, with reference to Figure 9 the moving path of the bedding box unit 120 in the cabinet body 110 in some embodiments of the present invention will be briefly described.

[0099] The first motor 151 of the first vertical driving device 150 rotates forward to drive the bedding box unit 120 in the first vertical space to move downward from top to bottom. When the corresponding bedding box unit 120 moves to align its box opening 12101 with the cabinet opening 1111, medical staff can pick up and place the bedding. When the bedding box unit 120 moves to the bottom of the first vertical space, the bottom driving device 180 is controlled to move below the first vertical space, and the lifting platform 182 is raised. As the first motor 151 continues to rotate, the bedding box unit 120 gradually moves from the first vertical space to the bottom space and abuts against the lifting platform 182. When the bedding box unit 120 abuts against the lifting platform 182, the lifting platform 182 is made to synchronously descend as the first motor 151 continues to rotate until the bedding box unit 120 disengages from the vertical guide rail 130 and completely enters the bottom space.

[0100] Subsequently, the bottom driving device 180 moves the bedding box unit 120 below the second vertical space, and then the lifting platform 182 raises the bedding box unit 120. When the slider 1211 of the bedding box unit 120 slides into the second chute 132 and the top end of the lead screw nut 123 abuts against the second lead screw 162, the second motor 161 is made to drive the second lead screw 162 to first reverse a preset angle (such as 30°, 45°, 90°, 180°, etc.) and then rotate forward to ensure that the lead screw nut 123 meshes with the second lead screw 162. Alternatively, when the lead screw nut 123 floats to the lowest position before contacting the second lead screw 162, the second motor 161 can also be made to directly drive the second lead screw 162 to rotate forward.

[0101] Subsequently, the second motor 161 of the second vertical driving device 160 rotates forward to drive the bedding box unit 120 in the second vertical space to move upward from bottom to top. When the bedding box unit 120 moves to the top space, the top driving device 170 pushes the bedding box unit 120 to move to a position aligned with the first vertical space. Then, the first motor 151 is first made to drive the first lead screw 152 to reverse a preset angle (such as 30°, 45°, 90°, 180°, etc.) and then rotate forward to ensure that the lead screw nut 123 meshes with the first lead screw 152, thereby ensuring that the slider 1211 of the bedding box unit 120 can slide into the first chute 131 of the vertical guide rail 130.

[0102] The following refers to Figures 11 to 15 to elaborate in detail on the principle of synchronous opening of the bedding box unit 120 and the cabinet 110. Among them, Figures 11 to 15 the position reference line 200 shown in is used to facilitate those skilled in the art to understand the position change of the bedding box unit 120.

[0103] As shown in Figure 11 and Figure 12As shown, when the second vertical rack 1212 on the box body 121 is located above the gear 114, the first vertical rack 1131 on the cabinet body cover 113 meshes with the gear 114. The second stop structure 1221 that can swing left and right on the box cover 122 interferes with the first stop structure 1132 in the vertical direction before the box cover 122 is opened and does not interfere with the pushing structure 1112.

[0104] As Figure 12 and Figure 13 shown, when the second vertical rack 1212 on the box body 121 meshes with the gear 114, as the bedding box unit 120 continues to descend, the box body 121 drives the cabinet body cover 113 to slide upward through the meshing among the second vertical rack 1212, the gear 114, and the first vertical rack 1131.

[0105] As Figure 13 and Figure 14 shown, when the cabinet body cover 113 slides upward until the first stop structure 1132 on it abuts against the second stop structure 1221 on the box body 121, as the bedding box unit 120 continues to descend, the cabinet body cover 113 drives the box body 121 to slide upward together through the abutted first stop structure 1132 and second stop structure 1221.

[0106] As Figure 14 shown, when the box body 121 slides upward until the second stop structure 1221 on the box cover 122 abuts against the inclined bottom surface of the pushing structure 1112 on the first cabinet body 111, or before the second stop structure 1221 on the box cover 122 abuts against the inclined bottom surface of the pushing structure 1112 on the first cabinet body 111, the cabinet opening 1111 and the box opening 12101 are opened simultaneously. At this time, medical staff can take out the bedding in the box body 121 and put the bedding into the box body 121.

[0107] As Figure 14 and Figure 15 shown, when the box body 121 slides upward until the second stop structure 1221 on the box cover 122 abuts against the inclined bottom surface of the pushing structure 1112 on the first cabinet body 111, as the bedding box unit 120 continues to descend, the second stop structure 1221 continues to rise. Under the action of the inclined bottom surface of the pushing structure 1112, the second stop structure 1221 is pushed in the horizontal direction, so that the second stop structure 1221 swings to a position where it is disengaged from the interference with the pushing structure 1112. At this time, the box cover 122 falls back under the action of its own gravity or the reset member and covers the box opening 12101 again. Further, as the bedding box unit 120 continues to descend, the second vertical rack 1212 disengages from the gear 114, and thus the cabinet body cover 113 falls back under the action of its own gravity or the reset member to a position where it covers the cabinet opening 1111 again.

[0108] In an application scenario of the automatic bedding distribution device 100 of the present invention, a touch screen and a card-swipe area are further provided on the cabinet 110, so that medical staff can understand how many sets of clean bedding are left in the automatic bedding distribution device 100 according to the information displayed on the touch screen, and so that medical staff can issue instructions to the automatic bedding distribution device 100 to pick up and place bedding through the touch screen. The card-swipe area is used to identify the ID cards of medical staff. When a medical staff places their ID card on the card-swipe area, the ID recognition device built in the automatic bedding distribution device identifies the identity information of the medical staff to authorize the medical staff to pick up and place bedding when the identity information authentication is successful.

[0109] In this application scenario, first, the staff in the warehouse put clean bedding into the bedding box unit 120, and then the medical staff pick up and place the bedding according to their needs.

[0110] When the staff in the warehouse put clean bedding into the bedding box unit 120, the bedding box unit 120 can move sequentially along the following path: the first vertical space → the bottom space → the second vertical space → the top space → the first vertical space, or can also move sequentially along the following path: the first vertical space → the top space → the second vertical space → the bottom space → the first vertical space.

[0111] When the medical staff exchange bedding (pick up clean bedding and put in the bedding to be cleaned), or only pick up bedding (only pick up clean bedding without putting in the bedding to be cleaned), the bedding box unit 120 can move sequentially along the following path: the first vertical space → the bottom space → the second vertical space → the top space → the first vertical space.

[0112] Based on the foregoing description, those skilled in the art can understand that the automatic bedding distribution device 100 of the present invention not only facilitates the medical staff to pick up and place bedding, but also has a compact and simple structure, and can also make the bedding box unit 120 and the cabinet 110 open the lids synchronously.

[0113] As Figures 16 to 18 shown, in some other embodiments of the present invention, the automatic bedding distribution device 100 further includes at least one support seat 190 that does not interfere with the lead screw nut 123. The support seat 190 is disposed on the side of the lead screw away from the lead screw nut 123 and is fixedly connected to the cabinet 110. Exemplarily, there are multiple support seats 190, and a part of the support seats 190 are fixed to the front side wall of the cabinet 110 by bolts, and a part of the support seats 190 are fixed to the rear side wall of the cabinet 110 by bolts.

[0114] As Figure 16 and Figure 17As shown, a concave curved surface 191 is provided on one side of the support base 190 close to the lead screw nut 123. The concave curved surface 191 matches and abuts against the circumferential surface of the lead screw, so that the support base 190 and the lead screw nut 123 jointly fix the lead screw (the first lead screw 152 or the second lead screw 162) in the horizontal direction.

[0115] As Figure 18 shown, the support base 190 fixed to the front side wall of the cabinet body 110 and the lead screw nut 123 jointly clamp the first lead screw 152 in the middle in the horizontal direction, and thus the first lead screw 152 is fixed in the horizontal direction.

[0116] Those skilled in the art can understand that by clamping the lead screws (the first lead screw 152 and the second lead screw 162) in the horizontal direction by the support base 190 and the lead screw nut 123, the lead screws (the first lead screw 152 and the second lead screw 162) are prevented from bending and deforming during long-term use, and the (first lead screw 152 and the second lead screw 162) are prevented from disengaging from the engagement with the lead screw nut 123 due to deformation. Thereby ensuring the reliability of the engagement between the lead screws (the first lead screw 152 and the second lead screw 162) and the lead screw nut 123 and the service life of the lead screw.

[0117] Preferably, the contour of the cross-section of the concave curved surface 191 is a part of a circle, and this part is preferably not more than half of the circle.

[0118] Further preferably, each lead screw corresponds to at least three support bases 190, and the at least three support bases 190 are evenly distributed along the axial direction of the lead screw.

[0119] As Figure 16 and Figure 17 shown, an oil injection groove 192 is provided on the concave curved surface 191. The oil injection groove 192 is used to receive grease and coat the received grease on the lead screw (the first lead screw 152 or the second lead screw 162).

[0120] As Figures 16 to 18 shown, an oil storage cavity 193 is provided at the top of the support base 190. The support base 190 is also provided with a channel 194 communicating the oil storage cavity 193 with the oil injection groove 192. The oil storage cavity 193 is used to store grease, and the grease in the oil storage cavity 193 flows to the oil injection groove 192 through the channel 194 under the action of its own gravity.

[0121] From Figure 17 and Figure 18 it can be seen that the bottom surface of the oil storage cavity 193 gradually slopes downward from the end far away from the channel 194 to the end close to the channel 194, so that the grease in the oil storage cavity 193 can flow along the bottom wall of the oil storage cavity 193 to the channel 194 to avoid waste of grease.

[0122] The lubrication principle of the support base 190 for the lead screw is as follows: The grease in the oil storage cavity 193 can flow through the channel 194 to the oil injection groove 192 under the action of its own gravity, so as to be coated on the lead screw (the first lead screw 152 or the second lead screw 162). As the lead screw nut 123 moves up and down relative to the lead screw, the grease on the lead screw (the first lead screw 152 or the second lead screw 162) is evenly coated on the entire lead screw by the lead screw nut 123, thereby realizing the lubrication of the entire lead screw.

[0123] Those skilled in the art can understand that in some other embodiments of the present invention, the setting of the support base 190 not only ensures the reliability of the lead screw during operation, but also realizes the lubrication of the lead screw.

[0124] So far, the technical solutions of the present invention have been described in combination with multiple foregoing embodiments. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the technical principle of the present invention, those skilled in the art can split and combine the technical solutions in the above-mentioned various embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc. made within the technical concept and / or technical principle of the present invention will fall within the protection scope of the present invention.
