[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0028] Example 1
[0029] Reference Figure 1-4 , which is the first embodiment of the utility model, provides an oil filling barrel, which includes a mobile base 1 and a barrel body 2, the barrel body 2 is installed on the top of the mobile base 1, the surface of the barrel body 2 is provided with a pressure relief component 3, the interior of the barrel body 2 is provided with a barrel internal component 4, the outer side of the mobile base 1 is provided with an oil filling body 5, the pressure relief component 3 includes a pressure relief cabin 31, the pressure relief cabin 31 is fixedly installed on the surface of the barrel body 2, the outer side of the pressure relief cabin 31 is provided with pressure relief holes 32, the pressure relief holes 32 are distributed in a ring array around the pressure relief cabin 31, one end of the pressure relief cabin 31 is provided with a ventilation pipe 34, the ventilation pipe 34 is fixedly installed on the inner side of the barrel body 2, and a pressure equalization component 33 is provided between the pressure relief cabin 31 and the ventilation pipe 34.
[0030] The pressure equalizing assembly 33 includes a pressure equalizing cabin 331, and the ventilation pipe 34 is fixedly installed on the inner side of the pressure relief cabin 31 through the pressure equalizing cabin 331. A limiting ring 332 is fixedly installed on the inner side of the pressure equalizing cabin 331. The inner side of the limiting ring 332 is movably connected with a pressure relief shaft 333, and the pressure relief shaft 333 runs through the entire limiting ring 332.
[0031] A pressure relief spring 334 is disposed on the outer side of the limiting ring 332 , and the pressure relief spring 334 is located on the outer side of the pressure relief shaft 333 .
[0032] An impact chamber 335 is fixedly installed on one end of the pressure equalizing chamber 331 away from the pressure relief chamber 31 , and an impact spring 336 is arranged on the inner side of the impact chamber 335 .
[0033] One end of the impact spring 336 is provided with a pressure equalizing shaft 337 , which is movably connected to the inner side of the impact chamber 335 , and the other end of the pressure equalizing shaft 337 is fixedly connected to a rubber plug 338 , which is located on the inner side of the ventilation pipe 34 .
[0034] During use, when the barrel body 2 shakes but the pressure inside the barrel body 2 changes, the changing pressure causes the rubber plug 338 in the vent pipe 34 to move toward the end close to the impact chamber 335 and squeeze the pressure equalizing shaft 337, causing the extension length of the impact spring 336 to change. When the pressure value is within the range of the impact spring 336, the extension length of the pressure relief spring 334 remains unchanged. When the deformation of the impact spring 336 reaches a maximum, the pressure equalizing shaft 337 moves on the inner side of the impact chamber 335 and finally squeezes the pressure relief shaft 333, causing the length of the pressure relief shaft 333 in the pressure relief chamber 31 to increase. The pressure relief spring 334 moves under the restriction of the limit ring 332, and the extension length of the pressure relief spring 334 decreases. As the pressure relief shaft 333 moves, the blockage of the pressure relief hole 32 is finally released, allowing air to enter from the pressure relief hole 32 and offset the pressure in the barrel body 2. As a result, the internal pressure cannot be released in time when it is impacted, so that the strength of the container may not be able to withstand it, resulting in the barrel body rupture, causing the probability of butter leakage.
[0035] Example 2
[0036] Reference Figure 1-5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:
[0037] The barrel internal component 4 includes an oil delivery pipe 41 and a pressure supply assembly 42. The pressure supply assembly 42 includes a piston rod 421. One end of the piston rod 421 protrudes from the top of the barrel body 2. A rubber piston 422 is fixedly installed at the bottom of the piston rod 421. One end of the oil delivery pipe 41 protrudes from the entire rubber piston 422. A first support shaft 423 is fixedly installed at the bottom of the rubber piston 422.

[0039] The oil filling body 5 includes an oil filling hose 51, one end of which extends to the interior of the barrel body 2, and an oil filling gun 52 is installed at one end of the oil filling hose 51. A control valve 53 is provided on the surface of the oil filling gun 52, and an oil filling interface 54 is installed on the outer side of the oil filling gun 52.
[0040] During use, butter can be added to the barrel body 2 through the oil delivery pipe 41. When the piston rod 421 is pulled, the position of the rubber piston 422 in the barrel body 2 changes, thereby pumping out the butter in the barrel body 2. When the height of the threaded ring 432 changes due to the connected rubber piston 422 and the screw 431, the screw 431 with the inner thread connection drives the connected stirring rack 435 to stir the butter stored in the barrel body 2 under the restriction of the bearing 434, thereby reducing the probability of the butter in the barrel body 2 solidifying. The pumped butter is transported by the oil filling hose 51 and filled through the oil filling interface 54 on the oil filling gun 52. In this process, the control valve 53 is used to control the butter filling speed of the oil filling gun 52, making the butter filling process simpler and more convenient.
