DETAILED DESCRIPTION

[0019] 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.

[0020] like Figures 1 to 3 As shown, the utility model provides a sealing device for transporting chemical liquids, comprising a cart 1, a mobile base 2, a plastic barrel 3 and a feed port 4, the mobile base 2 is fixedly connected to a triangle at the bottom of the cart 1, the plastic barrel 3 is located on the inner side of the cart 1, the feed port 4 is opened at the top of the plastic barrel 3, the four corners of the top of the plastic barrel 3 are fixedly connected with fixed columns 5 close to the side of the feed port 4, a through hole 6 is opened on the top of the surface of the fixed column 5, a sealing ring 7 is fixedly connected to the top of the feed port 4, a sealing groove 8 is opened inside the sealing ring 7, a rubber sealing cover 9 is inserted inside the sealing groove 8, and a pressing mechanism 10 is inserted inside the through hole 6.

[0021] refer to Figure 1 The pressing mechanism 10 includes a pressing rod 101, which is slidably connected to the inside of the through hole 6. A pressing block 102 is fixedly connected to the inner side of the pressing rod 101. A limiting hole 103 is opened on the surface of the pressing rod 101, and a pressing assembly 104 is clamped inside the limiting hole 103.

[0022] As a technical optimization scheme of the utility model, by setting a pressing mechanism 10, the pressure rod 101 is plugged into the limiting hole 103, and the inner end of the pressure rod 101 is fixed to the pressure block 102. When the feed port 4 needs to be sealed, the pressure rod 101 is pushed to drive the pressure block 102 to press the rubber sealing cover 9, so that the rubber sealing cover 9 can fit firmly with the slot, thereby ensuring the sealing.

[0023] refer to Figure 1 The pressing assembly 104 includes a limiting rod 1041, which passes through the fixing column 5 and is clamped in the limiting hole 103. The outer side of the top of the fixing column 5 is fixedly connected with a mounting column 1042, and the bottom of the mounting column 1042 is fixedly connected with a pressure assembly 1043.

[0024] As a technical optimization solution of the utility model, by setting the pressing component 104, the limiting rod 1041 and the limiting hole 103 can be snap-fitted together. When the pressure rod 101 needs to be limited and the clamping force of the pressure block 102 and the pressure rod 101 is ensured, the limiting rod 1041 is snap-fitted and fixed with the limiting hole 103 to avoid the pressure rod 101 from self-movement, thereby ensuring the stability of the clamping.

[0025] refer to Figure 1 The pressure assembly 1043 includes a first limit block 10431, which is fixedly connected to the outer side of the bottom of the mounting column 1042. A spring 10432 is fixedly connected to the surface of the first limit block 10431. The other end of the spring 10432 is fixedly connected to the second limit block 10433. The bottom of the second limit block 10433 is fixedly connected to the top of the limit rod 1041.

[0026] As a technical optimization scheme of the utility model, by setting a pressure component 1043, the first limit block 10431 is fixed to the mounting column 1042, and then the first limit block 10431 is fixed to one end of the spring 10432, and then the other end of the spring 10432 is fixed to the second limit block 10433, and the second limit block 10433 is fixed to the limit rod 1041. After one end of the first lower limit block is fixed to one end of the spring 10432, the other end of the spring 10432 can generate elastic force transmitted to the second limit block 10433, so that the second limit block 10433 transmits the elastic force to the limit rod 1041, so that the limit rod 1041 is clamped and fixed to the limit hole 103, thereby ensuring the stability of the limit pressing.

[0027] refer to Figure 1 The bottom of the surface of the limiting rod 1041 is fixedly connected with a synchronization rod 11 , and the surface of the synchronization rod 11 is fixedly connected with an auxiliary ring 12 .

[0028] As a technical optimization solution of the utility model, by setting the synchronization rod 11 and the auxiliary ring 12, when the user needs to open the plastic barrel 3, by pulling the auxiliary ring 12, the auxiliary ring 12 will synchronously drive the limiting rods 1041 on both sides to separate from the limiting holes 103 through the synchronization rod 11, so that the user can take out the pressure rod 101 with his other hand, thereby improving the convenience of opening the plastic barrel 3.

[0029] refer to Figure 1 The outer side of the pressure rod 101 is fixedly connected with a take-out rod 13 , and the outer side of the take-out rod 13 is fixedly connected with a pull rod 14 .

[0030] As a technical optimization solution of the utility model, by setting a removal rod 13 and a pull rod 14, the removal rod 13 is fixed to the pressure rod 101, and then the removal rod 13 is fixed to the pull rod 14, so that the user can pull the pull rod 14 to drive the removal rod 13 to simultaneously drive the two pressure rods 101 to move outward, thereby improving the convenience of opening the plastic barrel 3.

[0031] refer to Figure 1 A handle 15 is fixedly connected to the top of the rubber sealing cover 9.

[0032] As a technical optimization solution of the utility model, by providing a handle 15, it is convenient for the user to open and install the rubber sealing cover 9 through the handle 15, thereby improving the convenience of opening and installing the rubber sealing cover 9.

[0033] The working principle and use process of the utility model are as follows: when in use, the mobile base 2 is fixed to the cart 1. When the plastic barrel 3 needs to be transported, the handle 15 is first picked up by manpower, so that the handle 15 drives the rubber sealing cover 9 to be plugged and installed with the sealing groove 8 of the sealing ring 7. In order to ensure the stability of the installation of the rubber sealing cover 9, the limiting rod 1041 is first lifted through the auxiliary ring 12 and the synchronous rod 11, and then the pressure rod 101 is moved inward, so that the pressure rod 101 drives the pressure block 102 to press the rubber sealing cover 9, and then the pressure rod 101 is moved inward, so that the pressure block 102 is pressed by the pressure rod 101 to press the rubber sealing cover 9. Release the auxiliary rod, so that one end of the first lower limit block is fixed with one end of the spring 10432, and the other end of the spring 10432 can generate elastic force to be transmitted to the second limit block 10433, so that the second limit block 10433 transmits the elastic force to the limit rod 1041, so that the limit rod 1041 is clamped and fixed with the limit hole 103, thereby ensuring the stability of the limit pressing and the sealing. Then, place the plastic barrel 3 on the inner side of the cart 1 for transportation. When it needs to be opened after being transported to the destination, the above steps can be reversed.

[0034] To sum up: this sealing device for transporting chemical liquids, by providing a pressing mechanism 10, enables the pressing mechanism 10 to press the rubber sealing cover 9, so that the rubber sealing cover 9 can fit firmly with the sealing groove 8 inside the sealing ring 7, thereby ensuring the sealing performance. It solves the problem that the feed port of the current plastic barrel is usually sealed with a threaded cover, and the threaded cover is prone to getting stuck when sealing, resulting in leakage of the chemical liquid. In addition, the installation and disassembly of the threaded cover are relatively cumbersome, and it is necessary to twist the threaded cover multiple times to install the plastic barrel, which is not convenient and has certain limitations.
