[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Referring to Figures 1-4 , a hanger for a cold storage translation door, comprising an outer sleeve body 1 and an inner lining body 2. A roller 3 is rotatably installed at the top of the outer sleeve body 1. The roller 3 is used to be arranged on the track 21 of the door frame. An embedding groove 4 is formed on one side of the outer sleeve body 1, and a support plate 5 is installed inside the embedding groove 4;

[0022] The inner lining body 2 includes a support block 6 and a connecting block 7 installed at the bottom of the support block 6. The connecting block 7 is L-shaped. The top and side of the support block 6 are respectively detachably connected to the inner wall of the embedding groove 4 and the bottom of the support plate 5 through bolt connection structures. First through holes 8 are formed at the end, side of the top of the connecting block 7 and the lower part of the outer sleeve body 1. The first through holes 8 are used to pass through fixing bolts 17 to be connected to the door panel 10.

[0023] When this hanger is in use, through the provided L-shaped connecting block 7, multi-point connection between the inner lining body 2 and the door panel 10 is realized by using the L-shaped structure. It can be fixedly connected to the side of the door panel 10 and also to the top surface of the door panel 10, greatly improving the connection strength between the hanger and the door panel 10. It is applicable to both the integral foamed cold storage door with a relatively high strength of the door panel 10 and the post-wrapped cold storage door with a relatively low strength of the door panel 10, solving the problem that in the prior art, when adjusting the bottom seal of the door panel 10, there is only one point of fixed connection at the top of the door panel 10 between the inner lining of the hanger and the door panel 10, and it is easy to occur the situation that the aluminum profile at the top of the door panel 10 is torn from the polyurethane board.

[0024] In this embodiment, a lead screw 11 is movably penetrated through the center of the roller 3, and one end of the lead screw 11 movably penetrates through the top of the outer sleeve body 1. Three nut locking mechanisms are arranged on the outer side of the lead screw 11. The three nut locking mechanisms are respectively located at both ends of the lead screw 11 and between the roller 3 and the outer sleeve body 1, and are used to lock the lead screw 11 on the outer sleeve body 1 and lock the roller 3 on the lead screw 11. Through the above structure, when installing the roller 3, first, the lead screw 11 is passed through the top of the outer sleeve body 1, then one end of the lead screw 11 is fixed on the outer sleeve body 1 by using two nut locking mechanisms, then the roller 3 is sleeved on the outer side of the other end of the lead screw 11, and then through another nut locking mechanism, the roller 3 is fixed between the two nut locking mechanisms to complete the installation of the roller 3.

[0025] In this embodiment, the nut locking mechanism includes a nut 12 adapted to the lead screw 11, a serrated washer 13 and a plain washer 14 arranged on one side of the nut 12. When used in cooperation with the nut 12, the locking on both sides of the lead screw 11 is achieved, which can achieve a good anti-loosening effect and avoid the situation that the bolts become loose due to vibration during the use of this hanger.

[0026] In this embodiment, the bolt connection structure includes a screw hole 15 formed in the support block 6 and a fastening bolt 16 passing through the outer sleeve 1 and screwed into the screw hole 15. That is, one fastening bolt 16 passes through the support plate 5 and is screwed into the screw hole 15 at the top of the support block 6, and the other fastening bolt 16 passes through the embedding groove 4 of the hanger and is screwed into the screw hole 15 at the side of the support block 6, completing the detachable connection between the support block 6 and the outer sleeve 1. This way can enable the outer sleeve 1 to provide a good supporting force for the roller 3 and improve the stability of the roller 3.

[0027] In this embodiment, a second through hole 9 is formed at a position corresponding to the fastening bolt 16 on the side of the outer sleeve 1. The length of the second through hole 9 is greater than the outer diameter of the fastening bolt 16, and the length of the first through hole 8 is greater than the outer diameter of the fixing bolt 17. This length design is for facilitating the adjustment of the bottom seal of the door panel 10. When the bottom seal of the door panel 10 needs to be adjusted, first loosen the fastening bolt 16 on the second through hole 9 and the fixing bolt 17 on the first through hole 8 by one turn, and then loosen the fastening bolt 16 at the top of the support block 6 by several turns. At this time, the inner lining 2 will fall together with the door panel 10. After reaching the predetermined position, finally tighten the fastening bolt 16 on the second through hole 9 and the fixing bolt 17 on the first through hole 8 to complete the adjustment of the bottom seal of the door panel 10. When the top seal of the door panel 10 needs to be adjusted, only the relative positions of the corresponding two groups of nut locking mechanisms on the lead screw 11 need to be adjusted, so as to control the change in the distance between the door panel 10 and the door frame 19, and make the sealing strip 20 press tightly against the door frame 19 to achieve the overall sealing effect of the cold storage door.

[0028] In this embodiment, limit frames 18 are installed at positions on the inner wall of the embedding groove 4 corresponding to the first through hole 8 and the second through hole 9, for restricting the positions of the fastening bolt 16 and the fixing bolt 17, so that the end positions of the fastening bolt 16 and the fixing bolt 17 will not change when adjusting the bottom seal of the door panel 10.

[0029] In this embodiment, the materials of the outer sleeve 1 and the inner lining 2 are both stainless steel, which improves their own load-bearing capacity and anti-corrosion ability.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
