DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-2 As shown, an automobile air-conditioning liquid storage-dryer assembly of an embodiment of the utility model includes a tank body 1 and a tank cover 10 installed at both ends of the tank body 1, an inner cavity 6 is formed inside the tank body 1, and both ends of the inner cavity 6 have assembly openings 11 for installing the tank cover 10, and two card slots 12 are correspondingly provided at the outer ends of the assembly openings 11, and two card slots 12 are correspondingly provided on the installation side of the tank cover 10, and the card slot 2 is formed with a receiving cavity 20, and a card tongue 21 is movably provided in the receiving cavity 20. When the tank cover 10 is in the installed state, the card slots 2 on both sides are inserted into the card slots 12, and the card tongues 21 and the card slots 12 form a limit clamping.

[0020] When in use, the two tank covers 10 are installed on the assembly openings 11 at both ends of the tank body 1 so that the utility model forms a relatively sealed state. When installing the tank cover 10, the clamping parts 2 on both sides are respectively inserted into the two corresponding clamping grooves 12 at the outer ends of the assembly openings 11. When the clamping parts 2 are in the inserted state, the clamping tongues 21 and the clamping grooves 12 form a limiting clamping to achieve the installation and fixation of the tank cover 10. When the tank cover 10 needs to be disassembled, the two clamping tongues 21 only need to be synchronously toggled to cancel the limiting clamping between the two clamps and the clamping grooves 12. The tank cover 10 of the utility model is very convenient for disassembly or installation, which effectively improves the convenience and practicality of daily maintenance of the liquid storage dryer.

[0021] The accommodating cavity 20 has a built-in pivot 3 and a torsion spring 30 is disposed on the outer sleeve of the pivot 3. The two contact ends of the torsion spring 30 are respectively against the latch tongue 21 and the clamping portion 2; the latch tongue 21 includes a pressing portion 22 located at the upper portion and a hook portion 23 located at the lower portion, and a rotating portion 24 rotatably connected to the pivot 3 is extended from the inner side of the latch tongue 21. A hook groove 25 adapted to the hook portion 23 is correspondingly opened on the inner side wall of the clamping slot 12; a guiding inclined surface 13 is also formed on the inner side of the clamping slot 12 above the hook groove 25.

[0022] When in use, when installing the tank cover 10, the pressing parts 22 of the two latching tongues 21 are pressed synchronously and in the box, at this time, the two latching tongues 21 rotate around the pivot 3 as the axis and cause the torsion spring 30 to be in an energy storage state, at this time, the two clamping parts 2 are pushed into the two corresponding clamping grooves 12, and when the tank cover 10 reaches the specified position, the pressing of the pressing part 22 is cancelled, and at this time, the energy stored in the torsion spring 30 is released and causes the latching tongue 21 to retreat to the initial position, and the latching tongue 21 is reset and the hook part 23 at its lower part enters the hook groove 25 of the side wall of the clamping groove 12, and the installation and fixing of the tank cover 10 is completed by the limit clamping formed by the hook part 23 and the hook groove 25;

[0023] The guiding slope 13 is provided to ensure that the latch tongue 21 can smoothly enter the latch groove 12, so as to avoid the tank cover 10 from getting stuck when being installed.

[0024] A protrusion 26 is formed on the top surface of the pressing portion 22 , and a groove 27 adapted to the protrusion 26 is formed on the top of the accommodating cavity 20 .

[0025] When in use, the rotation path of the latch tongue 21 is limited by the limiting cooperation between the protrusion 26 and the abutting groove 27, so as to prevent the latch tongue 21 from rotating excessively and affecting its stable assembly and disassembly.

[0026] A spring fixing seat 4 is fixedly disposed on the inner bottom wall of the slot 12 , and a spring member 40 is installed on the spring fixing seat 4 .

[0027] During use, when installing the tank cover 10, the card-mounting part 2 is pushed into the card slot 12. The pushing of the card-mounting part 2 causes the spring member 40 to be compressed and store energy. Therefore, when the tank cover 10 is in the installed state, the spring member 40 always provides a force opposite to the installation direction to the card-mounting part 2. This force can further improve the locking stability between the latch tongue 21 and the card slot 12.

[0028] One of the tank covers 10 is provided with an expansion valve interface 5 , the other tank cover 10 is provided with a condenser interface 50 , and the tank body 1 is provided with a liquid replenishment pressure stabilizing port 51 .

[0029] When in use, the tank body 1 has a built-in filter filler, and the liquid replenishment and pressure-stabilizing port 51 is located below the filter filler, which is conducive to replenishing the liquid according to the size of the inside of the tank body 1 and the amount of liquid to ensure that the pressure in the dryer shell is in a safe and stable state. The condenser interface 50 is used to connect to the condenser; the expansion valve interface 5 is used to connect to the expansion valve.

[0030] An assembly boss 14 adapted to the assembly opening 11 is formed on the inner side of the tank cover 10 , and a guiding oblique waist 15 is formed on the outer end of the assembly boss 14 .

[0031] When in use, the assembly boss 14 and the guiding waist 15 are provided so that the tank cover 10 can be quickly put into place when assembled. The outer peripheral surface of the assembly boss 14 is provided with a plurality of sealing rings to further improve the sealing effect of the tank cover 10.

[0032] 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. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
