DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention discloses a split hinge sleeve, referring to Figures 1 to 5 as well as Fig. 9, which is applied to equipment that requires the door body and the box body to be hinged, such as refrigerators, upright freezers and other refrigeration equipment. The split hinge sleeve is installed on the upper end surface or the lower end surface of the door body, and is used in conjunction with the upper hinge or the lower hinge installed on the box body. The split hinge sleeve 100 includes a first half sleeve 110 and a second half sleeve 120 that are independent of each other, and the second half sleeve 120 is closer to the box body 400 than the first half sleeve 110. The first half sleeve 110 includes a first top plate 111 and a first extension part A112 and a first extension part B113 connected to the first top plate 111, and the first extension part A112 and the first extension part B113 are distributed in sequence along the length direction of the first top plate 111. The second half sleeve 120 includes a second top plate 121 and a second extension part A122 and a second extension part B123 connected to the second top plate 121, and the second extension part A122 and the second extension part B123 are distributed in sequence along the length direction of the second top plate 121. The cross-sectional shape of the first extension portion A112 and the second extension portion A121 is arc-shaped, preferably semicircular, and the first extension portion A112 and the second extension portion A122 form an axis hole 170 for accommodating the hinge axis.

[0028] The door body 300 is provided with a mounting hole A310 and a mounting hole B320, the first extension part A112 and the second extension part A122 are respectively adapted to be connected with the mounting hole A310, and the first extension part B113 and the second extension part B123 are respectively adapted to be connected with the mounting hole B320. When the first extension part A112, the second extension part A122, the first extension part B113 and the second extension part B123 are installed in place, the first top plate 111 and the second top plate 121 are respectively in contact with the upper end surface or the lower end surface of the door body 300. In addition, a sleeve gap 180 is formed between the first half sleeve 110 and the second half sleeve 120, which reserves a compression space for the sleeve 100 to be subjected to force caused by the compression of the door body 300 during the clamping and transportation of the refrigeration equipment.

[0029] A spring 500 is provided between the first top plate 111 and the door body 300. When the refrigeration device is in a stationary state, the spring 500 is in a stretched state; when the refrigeration device is in a clamped transportation state, the door body 300 is squeezed, and the second half sleeve 120 moves with the door body 300 toward the direction close to the box body 400, while the first half sleeve 110 does not move under the action of the spring 500, thereby ensuring that the hinge shaft 220 will not be deformed by force, thereby improving the reliability of the hinge shaft 220. It should be noted that when the door body 300 is squeezed, as the squeezing force continues to increase, the spring 500 gradually changes from a stretched state to an original state or even a compressed state, but the deformation of the spring 500 needs to ensure that it is not enough to drive the first half sleeve 110 to move, so as to ensure that the hinge shaft 220 will not be deformed by force.

[0030] The shapes of the second extension part A122 and the second extension part B123 are not specifically limited in this embodiment, and their main function is to fix the sleeve 100 on the door body 300, and to ensure that the sleeve 100 does not move relative to the door body 300 when the door body 300 rotates. Therefore, the cross-sectional shape of the second extension part A122 and the second extension part B123 can be rectangular, trapezoidal, arc-shaped, etc. In this embodiment, from the perspective of easy processing and product uniformity, the cross-sectional shape of the second extension part A122 and the second extension part B123 is set to be the same as the first extension part A112 and the first extension part B113, which is also arc-shaped, preferably semicircular.

[0031] In order to further improve the connection stability between the sleeve 100 and the door body 300, refer to Figures 6 to 8 The mounting hole A310 is provided with a stopper A314 along its axial direction, and the stopper A314 is a long strip-shaped protruding structure provided on the circumferential side wall of the mounting hole A310. The mounting hole B320 is provided with a stopper B324 along its axial direction, and the stopper B324 is a long strip-shaped protruding structure provided on the circumferential side wall of the mounting hole B320. The width of the stopper A314 and the width of the stopper B324 are respectively equal to the sleeve gap 180. When the sleeve 100 is installed in place, the stop portion A314 is located between the first extension portion A112 and the second extension portion A122, and one side end face of the first extension portion A112 abuts against one side end face of the stop portion A314, and one side end face of the second extension portion A122 abuts against the other side end face of the stop portion A314; the stop portion B324 is located between the first extension portion B113 and the second extension portion B123, and one side end face of the first extension portion B113 abuts against one side end face of the stop portion B324, and one side end face of the second extension portion B123 abuts against the other side end face of the stop portion B324.

[0032] Stop portion A314 and stop portion B324 also have a guiding function. When installing the sleeve 100, stop portion A314 has a guiding function for the first extension portion A112 and the second extension portion A122, and stop portion B324 has a guiding function for the first extension portion B113 and the second extension portion B123, which facilitates the installation of the sleeve 100.

[0033] The mounting hole A310 is a two-stage stepped hole. Figure 8The first section mounting hole A311 and the second section mounting hole A312 are provided with claws A150 on the outer side walls of the first extension part A112 and the second extension part A122, respectively, and the claws A150 are engaged with the step surface A313. Similarly, the mounting hole B320 is a two-stage stepped hole, which includes a first-stage mounting hole B321 and a second-stage mounting hole B322. The first-stage mounting hole B321 is closer to the outer end surface of the door body 300 than the second-stage mounting hole B322, and the diameter of the first-stage mounting hole B321 is smaller than the diameter of the second-stage mounting hole B322. A stepped surface B323 is formed between the first-stage mounting hole B312 and the second-stage mounting hole B322. The outer side walls of the first extension portion B113 and the second extension portion B123 are respectively provided with claws B160, and the claws B160 are engaged with the stepped surface B323. Through the engagement between the claws A150 and the stepped surface A313, and the engagement between the claws B160 and the stepped surface B323, the connection reliability between the sleeve 100 and the door body 300 is further improved, and the sleeve 100 is prevented from jumping out of the door body 300.

[0034] In order to facilitate the clamping of the claw A150 and the step surface A313, and the clamping of the claw B160 and the step surface B323, the first extension part A112 and the second extension part A122 are respectively provided with a connecting bar A130, and the first extension part B113 and the second extension part B123 are respectively provided with a connecting bar B140. The structure of the connecting bar A130 is the same as that of the connecting bar B140. In this embodiment, the structure is described by taking the connecting bar A130 as an example. The connecting bar A130 is a long strip structure arranged at the lower part of the first extension part A112 and the second extension part A122. The free end of the connecting bar A130 has no connection relationship with the side wall of the first extension part A112 and the side wall of the second extension part A122. The claw A150 is arranged at the free end of the connecting bar A130 and is arranged toward the side wall of the mounting hole A310. When the first extension part A112 and the second extension part A122 are inserted into the mounting hole A310, the claw A150 first abuts against the first section mounting hole A311 and gradually moves toward the second section mounting hole A312. At this time, the connecting strip A130 moves toward the side wall away from the mounting hole A310 under the extrusion force. When the claw A150 moves to the step surface A313, the claw A150 engages with the step surface A313. At this time, the connecting strip A130 is reset.

[0035] In order to further facilitate the installation of the shaft sleeve 100, the connecting bar A130 and the connecting bar B140 are respectively made of elastic materials so that the connecting bar A130 and the connecting bar B140 are easily deformed when subjected to force.

[0036] The end surface of the door body 300 is provided with a recess 330 for mounting the shaft sleeve 100, one end of the spring 500 is fixedly connected to the side wall of the recess 330, and the other end of the spring 500 is fixedly connected to the first top plate 111. Specifically, the side wall of the recess 330 is provided with a base 331 for connecting the spring 500, and one end of the spring 500 is fixedly connected to the base 331. The first top plate 111 is provided with a through hole 114 for fixing the spring 500, and the other end of the spring 500 is fixedly connected to the through hole 114.

[0037] Furthermore, a protective cover (not shown) is provided on the periphery of the recess 330 to shield the sleeve 100 and a portion of the hinge body 210 located on the door body 300 side, so as to prevent unnecessary wear on the sleeve 100 and the hinge body 210 during transportation of the refrigeration equipment.

[0038] The present invention further discloses a hinge 200, which includes a hinge body 210, which is installed on the upper end surface or the lower end surface of the box body 400, and the hinge body 210 is connected to a hinge shaft 220, and the outer periphery of the hinge shaft 220 is provided with a split hinge shaft sleeve 100 disclosed in this embodiment.

[0039] The present invention further discloses a refrigeration device, comprising a door body 300 and a box body 400, wherein the door body 300 and the box body 400 are rotatably connected via the hinge 200 disclosed in this embodiment, the hinge body 210 is connected to the box body 400, and the shaft sleeve 100 is connected to the door body 300. When the refrigeration device is in a stationary state, the spring 500 is in a stretched state; when the refrigeration device is in a clamping and transporting state, the door body 300 is squeezed, and the second half shaft sleeve 120 moves with the door body 300 toward the box body 400, while the first half shaft sleeve 110 does not move under the action of the spring 500, thereby ensuring that the hinge shaft 220 will not be deformed by force, thereby improving the reliability of the hinge shaft 220.
