DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-2 As shown, a combined automobile air-conditioning liquid storage dryer according to an embodiment of the utility model comprises a shell 1, an upper end cover 10 and a lower end cover 11 located at both ends of the shell 1, the upper end cover 10 is provided with an expansion valve interface 4, the lower end cover 11 is provided with a condenser interface 40, a liquid replenishment pressure stabilizing port 41 is provided on the shell 1, the upper end cover 10 and the lower end cover 11 are respectively fixedly mounted on both ends of the shell 1 through a detachable mechanism, the detachable mechanism comprises two first snap-fitting covers 2 correspondingly arranged on the outer circumferential surface of the upper end cover 10 or the lower end cover 11, two second snap-fitting covers 3 adapted to the first snap-fitting covers 2 are arranged at both ends of the shell 1, and the upper end cover 10 or the lower end cover 11 is fixedly mounted on both ends of the shell 1 through the snap-fitting between the first snap-fitting covers 2 and the corresponding second snap-fitting covers 3.
[0019] When in use, the upper end cover 10 and the lower end cover 11 are fixedly mounted on both ends of the housing 1 through a detachable mechanism, specifically, the fixed installation is achieved through the engagement between the first snap-fit cover 2 and the corresponding second snap-fit cover 3;
[0020] The upper end cover 10 and the lower end cover 11 of the utility model are fixedly installed at both ends of the shell 1 by snap-fitting. This installation method makes it very convenient to dismantle or install the upper end cover 10 or the lower end cover 11, ensuring the stable installation of the upper end cover 10 and the lower end cover 11. There is no need to provide additional bolts, screws and other parts, so that the product can be quickly disassembled and assembled, which is convenient for daily maintenance of the product.
[0021] Two assembly grooves 20 are correspondingly provided on the outer side of the first snap-fit cover 2, and the two assembly grooves 20 are both equipped with buckles 21. The upper end surface of the second snap-fit cover 3 is provided with a accommodating recess 30 and the outer side surface is correspondingly provided with two grooves 31. The inner top walls of the two grooves 31 are both provided with slots 32 that are connected to the accommodating recess 30, and the buckles 21 cooperate with the corresponding slots 32; fastening screws 22 are provided on the left and right sides of the first snap-fit cover 2 at the corresponding positions of the two assembly grooves 20, and the inner ends of the fastening screws 22 extend through the assembly groove 20 to fasten the buckles 21 in the assembly groove 20; the ends of the buckles 21 are formed with protrusions 23 and the protrusions 23 are provided with guiding oblique waists 24.
[0022] When in use, when installing the upper end cover 10 or the lower end cover 11, align the first snap-fit covers 2 on both sides with the two corresponding second snap-fit covers 3 on the housing 1, and then assemble the first snap-fit cover 2 and the second snap-fit cover 3. During the assembly process, the two buckles 21 of the first snap-fit cover 2 enter the accommodating recess 30 and pass through the two slots 32 respectively. After passing through the slots 32, the protrusions of the buckles 21 form a clamping limit with the slots 32 (the guiding waist 24 ensures that the protrusions pass through the slots 32 smoothly). In the above state, the first snap-fit cover 2 and the second snap-fit cover 3 are fitted together, and the buckles 21 and the slots 32 form a buckle 21 to cooperate with each other to complete the installation of the upper end cover 10 or the lower end cover 11;
[0023] When the upper end cover 10 or the lower end cover 11 needs to be removed, the two buckles 21 are bent toward each other through the two grooves 31, and the two buckles 21 are bent toward each other so that the relative position of the protrusion and the slot 32 changes. At this time, the limit locking between the buckle 21 and the corresponding slot 32 disappears and then the buckle 21 exits the slot 32. At this time, the first snap cover 2 is separated from the second snap cover 3, and the upper end cover 10 or the lower end cover 11 is disassembled;
[0024] The buckle 21 is fixedly installed in the assembly groove 20 by means of a fastening screw 22 to ensure its installation stability and facilitate daily maintenance and replacement of the buckle 21 .
[0025] The mating ends of the upper end cover 10 or the lower end cover 11 and the housing 1 are both formed with a boss portion 12 , the size of which is adapted to the inner cavity of the housing 1 , and a tight step surface 13 is formed between the boss portion 12 and the upper end cover 10 or the lower end cover 11 .
[0026] When in use, the upper end cover 10 and the lower end cover 11 can be quickly put into place when assembled through the boss portion 12 and the abutting step surface 13 .
[0027] The outer shell 1 and the mating sides of the upper end cover 10 or the lower end cover 11 are provided with a sealing ring groove 14, which is coaxially arranged with the outer shell 1 and has a sealing ring 15 built in; the outer ring of the outer shell 1 located at the sealing ring groove 14 is provided with an annular abutment groove 16, and the abutment step surface 13 is provided with an annular abutment rib 17 at the corresponding position of the annular abutment groove 16.
[0028] When in use, when the upper end cover 10 or the lower end cover 11 is installed, a sealing ring 15 is used to provide a soft seal between the upper end cover 10 or the lower end cover 11 and the housing 1;
[0029] When the upper end cover 10 or the lower end cover 11 is installed, the annular abutment rib 17 is located in the corresponding annular abutment groove 16, thereby providing a hard seal between the upper end cover 10 or the lower end cover 11 and the housing 1;
[0030] The soft seal of the sealing ring 15 and the hard seal of the annular groove 16 provide double sealing protection for the upper end cover 10 and the lower end cover 11.
[0031] It should also be pointed out that the terms used in the present invention, such as “front”, “rear”, “vertical”, “horizontal”, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description.
