DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a tin paste jar preventing outer cover loosening, including tank shell 1, the inside installation of tank shell 1 is equipped with inner tank 5, the top of inner tank 5 is provided with top cover 2, the inner wall of top cover 2 is connected with the top end outer wall of tank shell 1 by thread, the periphery side wall of inner tank 5 is fixedly installed with limiting strip 501, the inner wall of tank shell 1 is provided with limiting groove 502, limiting strip 501 is slidably installed in the inside of limiting groove 502, the bottom of tank shell 1 is provided with base 3, the surface of base 3 is provided with mounting groove 301, buffer assembly is arranged in the inside of mounting groove 301, and tank shell 1 is installed in the inside of mounting groove 301 and is arranged in the upper end of buffer assembly;

[0023] When in use, the limiting strip 501 is fixedly installed on the four side walls of the inner tank 5, and the corresponding limiting groove 502 is formed on the inner wall of the tank body shell 1, so that the inner tank 5 is effectively fixed inside the tank body shell 1, and the movement of the inner tank 5 in the horizontal direction is limited, that is, even if the inner tank 5 is subjected to vibration or external force impact, the shaking amplitude of the inner tank 5 can be greatly reduced, thereby enhancing the stability of the entire solder paste tank, and the mounting groove 301 formed on the surface of the base 3 is provided with a buffer assembly, which can absorb part of the impact force when the solder paste tank is subjected to vibration, thereby further reducing the impact on the inner tank 5 and the tank body shell 1.

[0024] The inner wall of the top cover 2 is provided with an internal thread 203, the top end outer wall of the tank body shell 1 is provided with an external thread 204, the internal thread 203 is threadedly connected with the external thread 204, and the close fit of the internal thread 203 and the external thread 204 can form an effective sealing structure to prevent the solder paste from leaking or deteriorating due to poor sealing during storage and transportation.

[0025] The top end surface of the tank body shell 1 is provided with a sealing groove 201, and the inner top end of the top cover 2 is provided with a sealing strip 202, which is embedded in the inner part of the sealing groove 201. The sealing strip 202 not only plays a sealing role, but also can increase the friction between the top cover 2 and the tank body shell 1 to a certain extent. When the top cover 2 is tightened, the sealing strip 202 will be tightly embedded in the sealing groove 201, thereby increasing the stability of the connection and preventing the top cover 2 from being accidentally loosened due to external impact or vibration.
