DETAILED DESCRIPTION

[0025] In order to further understand the content, features and effects of the present invention, the following examples are given in conjunction with the attached Figures 1 to 5 Detailed instructions are as follows.

[0026] like Figures 1 to 4 As shown, the first embodiment of the present invention provides a liquid cooling pipe installation structure, including a snap ring spring 1, a screw 3, a first nut 41 and a second nut 42;

[0027] The snap ring spring piece 1 includes a main body 11 and a bent portion 12 vertically connected to the main body 11. The snap ring spring piece 1 is provided with a first opening 21 for the free end of the bent main body 11 of the snap ring spring piece 1 to pass through. The free end of the main body 11 can move up and down relatively along the screw 2 in the first opening 21. The free end of the main body 11 and the bent portion 12 are sequentially passed through the screw 3 from top to bottom. The lower portion of the screw 3 is fixedly arranged on the bottom surface of the container, and the bottom end of the snap ring spring piece 1 abuts against the bottom surface of the container.

[0028] The first nut 41 and the second nut 42 are threadedly connected to the screw rod 3 . The first nut 41 and the second nut 42 are respectively in contact with the upper surface of the free end of the main body 11 and the lower surface of the bent portion 12 .

[0029] The utility model installs the liquid cooling pipe by adopting the cooperation of elastic clamping ring spring piece, screw rod, first nut and second nut, and limits the clamping ring spring piece by moving the first nut and the second nut up and down along the screw rod, thereby reducing the time for disassembling and assembling the liquid cooling pipe.

[0030] In this embodiment, Figure 1 and 3As shown, the bent main body 11 includes a snap ring spring piece insertion section 111, a first straight section 112, an arc section 113 and a second straight section 114 arranged in sequence, and the snap ring spring piece insertion section 111, the first straight section 112, the arc section 113 and the second straight section 114 together form a space for placing the liquid cooling pipe, wherein the snap ring spring piece insertion section 111 is the free end of the main body 11, and the second straight section 114 is vertically connected to the bending portion 12. In addition, the snap ring spring piece insertion section 111 and the bending portion 12 are respectively provided with a circular second opening 22 and a third opening 23 for the screw 3 to pass through.

[0031] In this embodiment, the main body 11 and the bent portion 12 are manufactured by integral molding or by welding. In addition, the retaining ring spring piece penetration section 111, the first straight section 112, the arc section 113 and the second straight section 114 are manufactured by integral molding to ensure overall elasticity.

[0032] In this embodiment, Figure 1 As shown, the width of the snap ring spring piece passing section 111 is smaller than the width of the first straight section 112. In addition, the widths of the first straight section 112, the arc section 113, the second straight section 114 and the bent portion 12 are the same, which makes it convenient for the snap ring spring piece passing section 111 to pass into the first opening 21.

[0033] In this embodiment, the main body portion 11 and the bent portion 12 are both sheet-shaped square structures with the same thickness to ensure overall consistency.

[0034] The first embodiment of the present utility model is as follows Figure 1 and 2 As shown, the liquid cooling pipe is placed in the bent snap ring spring piece 1, that is, the snap ring spring piece penetration section 111, the first straight section 112, the arc section 113 and the second straight section 114 form a space for placing the liquid cooling pipe. The bottom end of the arc section 113 abuts against the bottom surface of the container, and the shape of the first opening 21 is square. At this time, the upper end of the snap ring spring piece penetration section 111 abuts against the upper end surface of the first opening 21, and the first nut 41 and the second nut 42 play a limiting role. In addition, the height H1 of the first opening 21 is greater than or equal to the distance H2 from the lower surface of the bent portion 12 to the top of the screw 3 to ensure that the bent portion 12 can finally detach from the top of the screw 3.

[0035] When the installation structure needs to be disassembled, the clasp spring piece passing section 111 moves downward relative to the first opening 21, the bent portion 12 is removed from the top of the screw rod 3, and then the second nut 42 and the first nut 41 are removed in sequence. Then the clasp spring piece passing section 111 is moved upward and detached from the top of the screw rod 3. Since the outer surface of the liquid cooling pipe is circular, there is still space for movement in the space for placing the liquid cooling pipe, which facilitates the clasp spring piece passing section 111 to move along the top of the screw rod 3. Finally, the clasp spring piece passing section 111 is withdrawn from the first opening 21, and then the clasp spring piece 1 is restored to its original shape under the action of the rebound force. Figure 4 Normal status shown.

[0036] As a second embodiment of the present invention, Figure 5 As shown, the only difference from Example 1 is that a third nut 43 is provided at the upper end of the bending portion 12, and the second nut 42 and the third nut 43 have opposite thread rotation directions. The top of the screw 3 is provided with a first threaded portion and a second threaded portion (not shown in the figure) from top to bottom. The thread rotation direction of the first threaded portion is the same as the thread rotation direction of the third nut 43, and the thread rotation direction of the second threaded portion is the same as the thread rotation direction of the second nut 42. Of course, the thread rotation direction of the second threaded portion is also the same as the thread rotation direction of the first nut 41 below. The diameter of the first threaded portion is smaller than the diameter of the second threaded portion. For details, please refer to the content in CN214146211U. The utility model achieves compression of the bending portion 12 by providing a pair of opposite nuts consisting of the second nut and the third nut, thereby ensuring the stability of the entire installation structure.

[0037] The utility model also provides an energy storage container, which includes the installation structure of the liquid cooling pipeline.

[0038] The utility model described above only expresses the implementation methods of the utility model embodiments and should not be construed as limiting the scope of the utility model patent, nor does it impose any formal restrictions on the structure of the utility model embodiments. It should be pointed out that for those skilled in the art, without departing from the concept of the utility model embodiments, several changes and improvements can be made, which fall within the scope of protection of the utility model embodiments.
