[0036] Please refer to Figure 1 and Figure 2 The utility model provides an auxiliary fixing device for an industrial oil barrel oil pump in a preferred embodiment, comprising a fixing cylinder 100, a threaded clamping sleeve 200 and an elastic reset member 300.

[0037] The fixing cylinder 100 is used for inserting the oil pump and fixing the oil pump. The fixing cylinder 100 includes an insertion cylinder 110 arranged at the bottom and used for inserting into the oil barrel opening 101. The peripheral wall of the insertion cylinder 110 is provided with a clearance opening 111. A tensioning block 120 is hinged at the clearance opening 111. The tensioning block 120 can move through the clearance opening 111. The tensioning block 120 has a contracted state contracted inwardly and an open state opened outwardly. Figure 2 and Figure 4 , the tensioning block 120 is in an open state.

[0038] The threaded clamping sleeve 200 is threadedly connected to the fixed cylinder 100. The threaded clamping sleeve 200 is located above the tension block 120. The threaded clamping sleeve 200 is used to cooperate with the tension block 120 in the open state to clamp the edge of the oil barrel mouth 101. The elastic reset member 300 is provided with a center hole 310 for the oil pump to pass through. The oil pump pipe of the oil pump can pass through the center hole 310 to extend into the oil barrel 102. The elastic reset member 300 is elastically lifted and movably installed on the insertion cylinder 110, and is used to apply an elastic force to the tension block 120 in the contracted state. The elastic force is used to drive the tension block 120 to move from the contracted state to the open state.

[0039] The utility model provides an auxiliary fixing device for an industrial oil barrel pump. The pump can be inserted into a fixing tube 100 to achieve fixing, and the fixing is more convenient; the fixing tube 100 can use a threaded clamping sleeve 200 to cooperate with a tensioning block 120 in an open state to clamp the edge of the oil barrel mouth 101, so as to achieve the position fixation of the fixing tube 100 and the oil barrel, thereby achieving the relative fixation of the pump and the oil barrel, reducing the shaking of the pump, and there is no need to manually hold the pump when pumping oil, so both hands can be free for operation, and the operation is more convenient; when inserted, the tensioning block 120 can be switched to a contracted state, so that it can pass through the oil barrel mouth 101, and after passing through the oil barrel mouth 101, the tensioning block 120 can be restored to an open state by an elastic reset member 300 to facilitate the subsequent clamping of the edge of the oil barrel mouth 101, thereby making the operation more convenient. In addition, the clamping method of the tensioning block 120 and the threaded clamping sleeve 200 can adapt to oil barrel mouths 101 of different calibers within a certain range, thereby adapting to oil barrel mouths 101 of different specifications.

[0040] Reference Figure 3 and Figure 4 In some embodiments of the utility model, the outer peripheral edge of the bottom of the threaded clamping sleeve 200 is provided with a tapered surface 210 that narrows downward, so that the tapered surface 210 can be clamped with the oil barrel mouth 101, so that there is no radial movement space at the bottom of the fixed cylinder 100, and the position of the fixed cylinder 100 and the oil pump is more stable and will not loosen or move due to shaking. In order to facilitate the screwing of the threaded clamping sleeve 200, a polygonal prism 220 is provided on the upper end of the threaded clamping sleeve 200, so as to facilitate the operation of the wrench to screw. And the design of the tapered surface 210 can adapt to various specifications of the oil barrel mouth 101 within a certain range, thereby improving the scope of application of the device.

[0041] Reference Figure 3 and Figure 4 In some embodiments of the utility model, the tensioning block 120 is provided with a stop block 121, and the stop block 121 in the open state abuts against the inner wall of the insertion tube 110 to position the tensioning block 120 in the open state and prevent the stop block 121 in the open state from continuing to open outward, so that the stop block 121 in the open state can maintain the open state and cooperate with the threaded clamping sleeve 200 to clamp the edge of the oil barrel mouth 101.

[0042] Reference Figure 4 and Figure 6 In a further embodiment of the utility model, the upper end of the tension block 120 in the open state has a clamping plane 122 in contact with the bottom surface of the edge of the oil barrel mouth 101, and a reinforcing rib 123 is provided between the clamping plane 122 and the stop block 121, thereby improving the structural strength of the stop block 121 and preventing the stop block 121 from being easily damaged. In order to reduce the radial dimension of the tension block 120 when it is folded, a downwardly folding surface 124 is provided at the bottom of the outer circumference of the tension block 120.

[0043] Reference Figure 4 In a further embodiment of the utility model, the elastic return member 300 is in a circular ring shape, and a lifting column 320 extending vertically downward is provided at the bottom of the elastic return member 300. The fixed cylinder 100 is provided with a vertical hole 130 for the lifting and lowering activities of the lifting column 320. The lifting column 320 is inserted into the vertical hole 130 and can be lifted and lowered, thereby realizing the lifting and lowering activity guide. A compression spring 330 is sleeved on the lifting column 320 to apply an upward elastic force to the elastic return member 300, thereby pushing the tensioning block 120 in the contracted state to return to the open state.

[0044] Reference Figure 5 In a further embodiment of the utility model, a threaded shaft 321 is provided at the bottom of the lifting column 320, and the bottom of the threaded shaft 321 passes through the vertical hole 130 and is connected to a nut 322. The outer peripheral contour of the nut 322 is larger than the diameter of the vertical hole 130, thereby limiting the movable stroke of the lifting column 320 so that the lifting column 320 will not be separated from the vertical hole 130.

[0045] Reference Figure 4 and Figure 5 In a further embodiment of the utility model, an extension strip 112 is provided at the bottom of the insertion tube 110, a mounting block 113 extending inward is provided at the bottom of the extension strip 112, and a mounting block 113 is provided at the vertical hole 130. The extension strip 112 provides a larger installation space and allows the elastic reset member 300 to be as close to the bottom of the insertion tube 110 as possible, so that it is easier to be pressed down by the tension block 120 moving toward the contracted state. The outer peripheral edge of the upper end of the elastic reset member 300 is chamfered to prevent the sharp corner from contacting the tension block 120 and being easily damaged.

[0046] Reference Figure 2 and Figure 3 In a further embodiment of the utility model, the clearance opening 111, the extension bar 112, the mounting block 113, the lifting column 320, the compression spring 330, and the tensioning block 120 are all arranged in a plurality. Specifically, in order to avoid structural interference, the extension bar 112 and the clearance opening 111 are staggered in the circumferential direction, and in order to reduce mutual interference when the tensioning blocks 120 are gathered toward the center, three tensioning blocks 120 are evenly arranged along the circumferential direction.

[0047] Reference Figures 2 to 4 In some embodiments of the present invention, the fixed cylinder 100 also includes an external threaded cylinder 140 disposed at the upper end of the insertion cylinder 110, the outer circumferential diameter of the external threaded cylinder 140 is larger than the insertion cylinder 110, and the threaded clamping sleeve 200 is threadedly connected to the external threaded cylinder 140, thereby facilitating thread processing.

[0048] Reference Figures 2 to 4In some embodiments of the present invention, the fixing cylinder 100 further includes a clamping cylinder 150 disposed at the upper end of the external threaded cylinder 140, and a clamping member 160 is installed on the peripheral wall of the clamping cylinder 150 to clamp the oil pump housing embedded in the clamping cylinder 150. Specifically, threaded holes 151 are distributed circumferentially on the peripheral wall of the clamping cylinder 150, and the clamping member 160 is a clamping screw threadedly connected to the threaded hole 151, and the oil pump housing embedded in the clamping cylinder 150 can be clamped by the clamping screw to fix the oil pump.

[0049] When the fixing cylinder 100 needs to be removed from the oil drum, the elastic reset member 300 needs to be pressed down and the tension block 120 needs to be moved to the retracted state, which is inconvenient. Figure 7 The elastic reset member 300 is connected to the upper end of the tension block 120 through a connecting rope 340, so that when the elastic reset member 300 is pressed down, the tension block 120 can be automatically driven to retract inward, making it convenient to disassemble the fixing tube 100.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
