DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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] like Figure 1 As shown, a mobile cold storage of the present invention includes a chassis 1, a storage body 2 and a roller unit 3.

[0028] The chassis 1 is spaced apart from the ground and serves as a platform for supporting the storage body 2. A bracket is also provided on one side of the chassis 1 for installing an outdoor unit of the air conditioner.

[0029] The storage body 2 is fixed on the chassis 1. The storage body 2 is the main part of the cold storage. Equipment such as air conditioners and pipelines will be installed in the storage body 2. Some cold storages that can be used for display will also have a transparent double door on one side of the storage body 2.

[0030] A plurality of roller units 3 are arranged on the end surface of the chassis 1 facing the ground, and each roller unit 3 is arranged at intervals, so the plurality of roller units 3 include a plurality of first units 31 and at least one second unit 32. Since the chassis 1 is to carry a relatively large storage body 2, the end surface area of ​​the chassis 1 is relatively large, and only a plurality of first units 31 are evenly arranged on the chassis 1 along the edge of the end surface of the chassis 1, which cannot effectively carry the chassis 1, so at least one second unit 32 is arranged in the middle of the chassis 1 and away from the edge of the chassis 1, so as to support the middle of the chassis 1, so as to prevent the middle of the chassis 1 from being deformed and falling due to the heavy weight of the storage body 2.

[0031] The second embodiment of the present invention is achieved by the following means.

[0032] like Figure 1 As shown, combined Figure 2 The storage body 2 includes a first shell 21, a second shell 22 and a temperature insulation layer 23.

[0033] The first housing 21 is disposed on the chassis 1 as an outer shell.

[0034] The second shell 22 is arranged in the first shell 21 as an inner shell, and the outer wall of the second shell 22 is spaced apart from the inner wall of the first shell 21. Further, the second shell 22 includes a plurality of panels, and the plurality of panels surround the second shell 22, and the edges of the panels are abutted and welded. Compared with the currently common spliced ​​storage body 2, the second shell 22 of the present invention is surrounded by a plurality of panels welded, which can greatly improve the sealing performance of the storage body 2.

[0035] The thermal insulation layer 23 is filled between the first shell 21 and the second shell 22 to provide thermal insulation.

[0036] Since the cold storage is large in size and heavy in weight, the chassis 1 occupies a large area, which causes the roller unit 3 arranged on the chassis 1 to be tightly pressed against the ground under heavy pressure. Therefore, when the roller unit 3 is damaged, it is difficult to repair it. Therefore, the third embodiment of the present invention aims to solve this problem and is achieved by the following means.

[0037] like Figure 1 As shown, combined Figure 3 The first unit 31 or the second unit 32 includes a fixed portion 33, a movable portion 34 and a wheel body 35.

[0038] The fixing portion 33 is arranged on the end surface of the chassis 1 facing the ground.

[0039] One end of the movable part 34 is axially connected to the fixed part 33, and the other end of the movable part 34 extends in a direction away from the chassis 1. The end of the movable part 34 away from the chassis 1 can rotate relative to the fixed part 33 around the axial connection part and selectively move to the first position 301 or the second position 302.

[0040] The wheel body 35 is disposed at an end of the movable portion 34 away from the chassis 1 .

[0041] When the above technical solution is adopted, when the movable part 34 enters the first position 301, the wheel body 35 is in contact with the ground; when the movable part 34 enters the second position 302, the wheel body 35 is spaced apart from the ground; thereby, by rotating the movable part 34, the wheel body 35 is separated from the ground, and at the same time, there is no need to use equipment to lift the chassis 1.

[0042] The fourth embodiment of the present invention achieves the purpose of rotating the movable part 34 by the following means.

[0043] like Figure 1 As shown, combined Figure 4 The first unit 31 or the second unit 32 also includes a telescopic rod 36, one end of the telescopic rod 36 is hinged to the fixed part 33, and the other end of the telescopic rod 36 is hinged to the end of the movable part 34 away from the chassis 1, and the movable part 34 is pulled or pushed to rotate by the extension and retraction of the telescopic rod 36.

[0044] Furthermore, in the fifth embodiment of the present invention, in order to limit the rotation range of the movable part 34, the first unit 31 or the second unit 32 is provided to also include a limiting part 37, and the limiting part 37 is provided on the fixed part 33, and the limiting part 37 is located on the side of the fixed part 33 away from the telescopic rod 36. When the movable part 34 enters the first position 301, the movable part 34 is abutted against the limiting part 37, thereby preventing the telescopic rod 36 from pushing the movable part 34 to rotate too much, causing the movable part 34 to rotate past the first position 301 and then leave the ground again.

[0045] The chassis 1 occupies a large area, which may also make it difficult to repair the second unit 32 located in the middle of the chassis 1. Therefore, the sixth embodiment of the present invention solves this problem by the following means.

[0046] like Figure 1 As shown, combined Figure 6 The second unit 32 also includes a sliding seat 38 .

[0047] A slide groove 201 is provided on the end surface of the chassis 1 facing the ground, one end of the slide groove 201 extends toward the edge of the end surface of the chassis 1 and extends between two adjacent first units 31, and the other end of the slide groove 201 extends toward the middle of the end surface of the chassis 1.

[0048] The sliding seat 38 is arranged in the slide groove 201, and the sliding seat 38 can move relative to the chassis 1 along the extension direction of the slide groove 201. The fixing portion 33 is arranged on the end surface of the sliding seat 38 facing the bottom surface. Therefore, by moving the sliding seat 38, the second unit 32 is moved to the edge position of the chassis 1 for maintenance.

[0049] Furthermore, the slide groove 201 includes a first groove body 2011 and at least one second groove body 2012, one end of the first groove body 2011 extends toward the edge of the end face of the chassis 1, and the other end of the first groove body 2011 extends toward the middle of the end face of the chassis 1; one end of each second groove body 2012 extends toward each second unit 32 one by one, and the other end of each second groove body 2012 is connected to the first groove body 2011, and each second groove body 2012 is arranged at intervals, and each second groove body 2012 is arranged perpendicular to the extension direction of the first groove body 2011, so that when the multiple second units 32 arranged in the middle of the chassis 1 move, there will be no obstruction between each other.

[0050] In order to restrict the normal second unit 32 from moving relative to the chassis 1, the seventh embodiment of the present invention is implemented by the following means.

[0051] like Figure 1 As shown, combined Figure 5 , and also includes a limit assembly 4, which is arranged on the chassis 1; when the sliding seat 38 moves to the end of the slide groove 201 away from the end edge of the chassis 1, the limit assembly 4 can selectively limit the movement of the fixing portion 33 relative to the chassis 1.

[0052] Specifically, the limiting assembly 4 includes a first limiting member 41 , a second limiting member 42 and an inserting rod 43 .

[0053] The two first stoppers 41 are symmetrically arranged on the end surface of the chassis 1 facing the ground, and the two first stoppers 41 are respectively close to the edges of the end surface of the chassis 1 on both sides away from each other. The two first stoppers 41 are provided with first through holes.

[0054] The second limiting member 42 is disposed on the fixing portion 33 , and a second through hole is defined in the second limiting member 42 .

[0055] When the above technical solution is adopted, when the sliding seat 38 moves to the end of the slide groove 201 away from the edge of the end face of the chassis 1, the insertion rod 43 can be selectively inserted into the second through hole, and the two ends of the insertion rod 43 extend toward the two first limit members 41 respectively and extend outward through the first through hole, thereby limiting the movement of the second unit 32.

[0056] Furthermore, the limiting assembly 4 further includes at least one baffle 44 for limiting the second unit 32 from deflecting or rotating relative to the chassis 1 .

[0057] Among them, the baffle 44 is arranged on the end surface of the chassis 1 facing the ground, and each baffle 44 is located at the end of the slide groove 201 away from the end surface edge of the chassis 1; when the sliding seat 38 moves to the end of the slide groove 201 away from the end surface edge of the chassis 1, each baffle 44 respectively abuts against the fixing part 33.

[0058] Working principle:

[0059] When it is necessary to repair the roller units 3 belonging to the first unit 31 arranged at the edge of the chassis 1, the telescopic lever 36 is started to drive the movable part 34 to rotate to the second position 302, so that the wheel body 35 is out of contact with the ground, so that it is convenient for maintenance personnel to repair the first unit 31. Since the first unit 31 is located at the edge of the chassis 1, the first unit 31 is fastened to the chassis 1 through fixing bolts, and the maintenance personnel can remove the entire first unit 31 from the chassis 1 for maintenance. At this time, the other roller units 3 can still well support the chassis 1 and the storage body 2 thereon.

[0060] When it is necessary to repair the roller units 3 belonging to the second unit 32 arranged in the middle of the chassis 1, first remove the insertion rod 43, then move the second unit 32 along the slide groove 201 to the edge of the chassis 1, and then repair the second unit 32 in the same way as repairing the first unit 31. However, the second unit 32 is not fastened to the chassis 1 by fixing bolts, but is indirectly connected to the chassis 1 by the sliding seat 38, but the second unit 32 can still play the role of supporting the chassis 1; at the same time, the fixing part 33 can also be removed from the sliding seat 38, so as to repair the second unit 32.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
