[0021] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] As Figures 1 - 2 shown, the present application provides a tank body structure for storing solder paste, including a tank body 1 and an inner plug 3 installed on the opening of the tank body 1. The inner plug 3 is adapted to seal the opening of the tank body 1, and a pulling bar 31 is provided on the inner plug 3. The pulling bar 31 is used to pull the inner plug 3 away from the opening of the tank body 1;

[0024] At the same time, a sealing cover 2 is installed at the top of the tank body 1. A first thread (not shown in the figure) is provided on the inner wall of the sealing cover 2, and a second thread adapted to the first thread is provided on the tank body 1. Thus, under the mutual cooperation of the first thread and the second thread, the sealing cover 2 can be fixed at the top of the tank body 1. A sealing ring 23 is fixedly connected to the bottom edge of the sealing cover 2, and a sealing groove 11 adapted to the sealing ring 23 is provided on the tank body 1. The sealing ring 23 is snap-fitted into the sealing groove 11;

[0025] Threads 21 are provided on the outer wall of the sealing cover 2. The threads 21 are adapted to increase the friction when an external object contacts the sealing cover 2, so as to facilitate the rotation of the sealing cover 2

[0026] When it is necessary to seal the solder paste in the tank body 1, first snap the inner plug 3 onto the opening of the tank body 1, then cover the sealing cover 2 on the tank body 1, and drive by the sealing cover 2 to make the sealing ring 23 snap into the sealing groove 11. At the same time, rotate the sealing cover 2 so that the sealing cover 2 is screwed tightly onto the tank body 1, thereby realizing the sealed storage of the solder paste;

[0027] When the can body 1 needs to be opened, the cover 2 is rotated, and under the action of the sealing groove 11, the sealing ring 23 is separated from the cover 2, and then a pulling force is applied to the pull bar 31 to drive the inner plug 3 to separate from the opening of the can body 1, thereby opening the can body 1;

[0028] like Figures 3 - 4 As shown, at least three sets of locking units 4 are arranged at the bottom of the tank body 1, and buckle blocks 22 (such as Figure 1 As shown in the figure, the lock unit 4 includes a lock box 41 fixed to the bottom of the tank body 1, and the lock box 41 is hollow and forms a lock cavity, and a slot 411 communicating with the lock cavity is provided at the top of the lock box 41, and a step (not shown in the figure) is provided at the bottom of the buckle block 22, and a lock end 221 is formed under the action of the step of the buckle block 22, and the lock end 221 is suspended, and the lock end 221 is adapted to the slot 411, so that the lock end 221 can enter the lock cavity through the slot 411;

[0029] At the same time, a pressing plate 42 is slidably installed in the lock box 41. The pressing plate 42 is suitable for sliding up and down in the lock box 41. A spring 43 is installed between the pressing plate 42 and the bottom surface of the lock box 41. The spring 43 always applies elastic force to the pressing plate 42, so that the pressing plate 42 is always in the slot 411.

[0030] A protruding end (not shown) extends from a part of one side of the pressing plate 42, and a side groove 412 adapted to the protruding end of the pressing plate 42 is provided at the slot 411 on the side wall of the lock box 41 to limit the upward and downward movement range of the pressing plate 42;

[0031] When multiple groups of can bodies 1 need to be stacked, first stack the bottom of one group of can bodies 1 with the cover 2 on the top of another group of can bodies 1, and fit the lock end 221 into the slot 411, and press the top can body 1, so that the lock end 221 applies pressure to the pressure plate 42, and the pressure plate 42 shrinks toward the lock cavity and squeezes the spring 43. After the protruding end of the pressure plate 42 hits the inner wall of the side groove 412, the top can body 1 is rotated at this time, so that the lock end 221 is stuck in the side of the slot 411 in the lock box 41. After the pressure applied to the top can body 1 disappears, the pressure plate 42 presses the lock end 221 through the action of the spring 43, thereby achieving the purpose of stacking and limiting the can bodies 1;

[0032] When the stacked cans 1 need to be separated, pressure is applied to the top can 1, so that the pressure plate 42 squeezes the spring 43, and the top can 1 is rotated at this time, so that the lock end 221 is separated from the lock cavity of the lock box 41, thereby separating the stacked cans 1;

[0033] In summary, through the function of the slot 411, the locking end 221 is adapted to be inserted into the lock box 41 and abuts against the pressing plate 42. When pressure is applied to the tank body 1, due to the contraction of the spring 43, the pressing plate 42 contracts into the lock cavity of the lock box 41, and the locking end 221 is adapted to be inserted into the side of the slot 411 in the lock box 41. With the cooperation of the spring 43, pressure is applied to the locking end 221 through the pressing plate 42, realizing the limit fixation of the locking end 221 and achieving the effect of limiting and connecting the stacked tank bodies 1.

[0034] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any improvements and refinements within the spirit and principle of the present application and without departing from the principle of the present application should also be regarded as within the protection scope of the present application.
