TECHNICAL FIELD

[0001] The utility model relates to a hand feeding lubricating device, especially to the technical field of a grease gun applicable to low temperature environment. BACKGROUND

[0002] When the existing mechanical device operates, various lubricants are used to keep the mechanical joint elements connected with each other to operate normally, reduce abrasion and increase the service life of the mechanical device. Grease is one of the widely used lubricants.

[0003] Referring to Figure 6 As shown in the figure, a conventional grease gun 9 disclosed in Chinese Utility Model CN206592739U "Compression rod type grease gun" comprises a gun body 91, an oil injection device 92, a channel 93, a compression rod 94 and a push rod 95. The push rod 95 is arranged at the bottom of the gun body 91, and its purpose is to push the grease in the grease tank. However, in a low temperature environment, the grease is more solidified and difficult to push due to the temperature influence. The operator needs to push the push rod 95 to extrude the grease into the conventional grease gun 9. The process is more difficult and time-consuming. Therefore, it is necessary to improve. SUMMARY

[0004] Therefore, in view of the problems of the conventional grease gun, the main purpose of the utility model is to provide a grease tank locking structure of a grease gun applicable to low temperature environment. The secondary purpose of the utility model is to provide a grease tank locking structure of a grease gun applicable to different shaped grease tanks.

[0005] To achieve the above purpose, the utility model uses the following technical means:

[0006] The utility model provides a grease tank locking structure of a grease gun, which is characterized by comprising:

[0007] A gun body is internally provided with a containing space with an opening, and an elastic body is placed in the containing space and a grease tank with an outlet can be placed;

[0008] An upper cover is provided with a bottom hole groove connected to the outer periphery of the opening of the gun body;

[0009] A compression rod is connected to the outer side of the upper cover; and

[0010] A adapter ring set is disposed between the end face of the opening of the gun body and the bottom hole groove of the upper cover, and the adapter ring set further comprises a first adapter ring and a second adapter ring; when the second adapter ring is connected to a first combination screw hole of the first adapter ring, a second combination screw hole of the second adapter ring provides connection with the outlet of the grease tank; or, when the second adapter ring is not used, the first combination screw hole of the first adapter ring provides connection with the outlet of another grease tank.

[0011] Wherein, the elastic body is a spring.

[0012] Wherein, the gun body further comprises a fixing screw and a fixing nut, and the fixing screw is disposed at the bottom of the gun body and is pivoted to the elastic body.

[0013] Wherein, the fixing screw is provided with a through hole, and the elastic body is provided with a tail end which penetrates and connects to the through hole.

[0014] Wherein, the grease tank is connected to the adapter ring set, the elastic body is compressed and deformed by abutting against the bottom of the grease tank, and the gun body is connected and fixed to the upper cover, so as to form the upper cover, the adapter ring set, the grease tank, the elastic body and the gun body from top to bottom.

[0015] By the above technical means, the following effects can be achieved:

[0016] 1. The spring abuts against the bottom of the grease tank, and when the operator uses the grease gun, the spring gives a spring force to further compress the grease tank, so that the grease gun can smoothly discharge the grease, thereby avoiding the grease from being stuck due to temperature influence.

[0017] 2. The adapter ring set can be applied to different models of grease tanks, smaller grease tanks can be connected to the second adapter ring, then connected to the first adapter ring and the upper cover, and larger grease tanks can be directly connected to the first adapter ring and the upper cover, thereby facilitating the operator to select different models of grease tanks.

DETAILED DESCRIPTION

[0025] As shown in the figure, the utility model provides a butter tank locking structure of butter gun, for the adaptor use and fixation of different butter tanks 6, comprising a gun body 2, an upper cover 3, a pressing rod 4 and an adaptor ring group 5; the above components are described as follows in combination with the attached drawings.

[0026] As shown in the figure, Figures 1 to 3 The above gun body 2 is internally provided with an accommodation space 22 with an opening 21, and an elastic body 23 is placed in the accommodation space 22, and a butter tank 6 with an outlet 61 is placed in the accommodation space 22, and the gun body 2 further comprises a fixing screw 24 and a fixing nut 25, and the fixing screw 24 is arranged at the bottom of the gun body 2 and is pivotally connected to the elastic body 23 in combination with the fixing nut 25, and the elastic body 23 is a spring.

[0027] As shown in the figure, Figures 2 to 3 The above upper cover 3 is provided with a bottom hole groove 31 connected to the outer periphery of the opening 21 of the gun body 2.

[0028] As shown in the figure, Figure 1 And Figure 2 The above pressing rod 4 is arranged on the outer side of the upper cover 3.
