[0046] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0047] Example 1

[0048] like Figures 1-4 The connecting assembly of an oil storage tank shown includes: a transition assembly 2, on which a connecting groove 21 is formed, and an oil outlet hole 22 is opened at the bottom of the connecting groove 21.

[0049] When the transition component 2 is connected to the oil storage tank 4, the end of the oil storage tank 4 is connected to the connecting groove 21, and the oil outlet 41 of the oil storage tank 4 is inserted into the oil outlet hole 22.

[0050] When the operator uses the piston handle 42, the piston rod 43 can be moved. In conjunction with the spring 44, the piston rod 43 is reset to draw the grease in the oil reservoir 4 and the grease inside the oil reservoir 4 is ejected through the oil outlet 41.

[0051] Since the structures of oil reservoirs 4 on the market are not entirely the same, sometimes the purchased oil reservoir cannot be directly installed on the grease gun for use. In this technical solution, a replaceable transition component 2 is provided at the end of the oil reservoir 4, which makes it easier to install the oil reservoir 4 onto the grease gun.

[0052] Furthermore, transition component 2 includes:

[0053] The connector body 3 has a connecting pipe portion 31 protruding from its front end, an oil outlet 22 is opened in the connecting pipe portion 31, and a connecting groove 21 is formed at the rear end of the connector body 3.

[0054] The fastener 5 is connected to the front end of the connector body 3, and the fastener 5 has a through hole 52.

[0055] The sealing element 33 is disposed between the connector body 3 and the fixing element 5.

[0056] The bottom of the connecting groove 21 is also provided with bolt holes 36; the fastener 5 is provided with threaded holes 39, the position of which matches the bolt holes 36, so that the fastener 5 can be connected to the connecting body 3 by fastening bolts 7.

[0057] When the fixing member 5 is connected with the connecting member body 3, the connecting pipe part 31 passes through the through hole 52. And with the screwing of the fastening bolt 7, the sealing member one 33 can be clamped between the connecting member body 3 and the fixing member 5, so as to further improve the sealing effect.

[0058] As shown in Figures 2-4 , the connecting pipe part 31 is formed with an annular groove 32, and the annular groove 32 is used to set the check ring 54.

[0059] When the connecting member body 3 is connected with the fixing member 5, the connecting pipe part 31 and the annular groove 32 thereon pass through the through hole 52, and at this time, the check ring 54 is set in the annular groove 32, and the check ring 54 can abut against the surface of the fixing member 5, so as to limit the connecting pipe part 31 from being pulled out of the through hole 52, and improve the connection strength between the connecting member body 3 and the fixing member 5.

[0060] As shown in Figures 2-4 , the sealing member one 33 is formed with a positioning column 38 protruding therefrom, and a threaded hole 39 penetrates the positioning column 38.

[0061] The fixing member 5 is provided with a positioning hole 51, and the position of the positioning hole 51 matches the position of the positioning column 38.

[0062] As a preferred embodiment, the front end of the fixing member 5 is recessed to form a recess 53, which can facilitate the connection of the fixing member 5 to the grease gun and prevent the grease from spilling out of the oil outlet hole 22 to the outside.

[0063] As shown in detail Figure 4 , the bottom of the connecting groove 21 is formed with a bolt mounting groove 37, and the bolt hole 36 penetrates the bottom of the bolt mounting groove 37.

[0064] The bottom of the connecting groove 21 is also provided with a sealing member two 34, and the sealing member two 34 is formed with a sealing lug 35, which can block the upper end of the bolt mounting groove 37, so that the sealing member two 34 can close the bolt mounting groove 37. Thus, during the use of the grease gun, the grease is prevented from flowing into the bolt mounting groove 37, which affects the removal of the fastening bolt 7 from the bolt mounting groove 37.

[0065] As shown in Figure 5 and Figure 6 , a grease gun includes a grease gun shell 1, and further includes a connecting assembly of an oil storage bucket as described above.

[0066] The front end of the grease gun shell 1 is provided with an oil outlet assembly 6, and the transition assembly 2 can be connected with the oil outlet assembly 6, and the oil storage bucket 4 can be arranged on the grease gun shell 1.

[0067] Further, the oil outlet assembly 6 includes:

[0068] The fixed seat 61, the transition assembly 2 is detachably connected at the rear end of the fixed seat 61;

[0069] The oil pipe 62 is connected at the front end of the fixed seat 61;

[0070] When the grease bucket 4 is connected to the oil outlet assembly 6 through the transition assembly 2, the grease in the grease bucket 4 can be filled to the designated position through the oil pipe 62.

[0071]

Embodiment Two

[0072] As shown in Figure 7 and Figure 8 In this embodiment, a threaded portion 23 is formed on the outer side wall of the transition assembly 2, so that the transition assembly 2 can be connected to the grease gun through threads.
