[0018] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-3 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.
[0019] Such as Figures 1-3As shown: This embodiment provides a grease injector for the maintenance of electrical equipment, including a filling tube 100. The cross-section of the filling tube 100 is circular. The filling tube 100 is a hollow tube that provides space for storing grease. There is an opening on one side of the filling tube 100, and the opening is a circular opening. A fixing ring 101 is provided at the circular opening. The fixing ring 101 is specifically a circular ring-shaped structure with a circular cross-section. The outer side of the fixing ring 101 is attached to and rotatably connected to the circular opening of the filling tube 100, and the fixing ring 101 extends a certain distance inside the filling tube 100. A cage 102 is installed inside the fixing ring 101. The cage 102 is specifically a circular cage 102. One side of the cage 102 is horizontally attached to the fixing ring 101 to form a closed space. The cage 102 is used to store a part of the grease and is used by taking out the grease during use. And through the limiting cooperation of the fixing ring 101, the cage 102 can prevent a large amount of grease in the filling tube 100 from flowing out at one time. When the cage 102 retracts, there is a certain space between the end of the cage 102 far from the opening of the filling tube 100 and the fixing ring 101. When the cage 102 extends, the fixing ring 101 can keep the cage 102 in a sealed state inside the filling tube 100. There is an opening on the side of the filling tube 100 far from the fixing ring 101, and the opening is a circular opening. A seal 103 is connected at the circular opening. The cross-section of the seal 103 is circular. The seal 103 is rotatably connected to the filling tube 100 at the circular opening of the filling tube 100. A chamber 104 is opened inside the seal 103. The chamber 104 is a circular chamber 104. First fixing members 105 are symmetrically provided inside the circular chamber 104 of the seal 103. The cross-section of the first fixing members 105 is circular. The first fixing members 105 are fixedly connected to the seal 103 inside the circular chamber 104 of the seal 103. Spring telescopic rods 106 are provided on each of the first fixing members 105. Perforations are opened at positions corresponding to the first fixing members 105 on the side of the seal 103 far from the fixing ring 101. The perforations are circular perforations. Second fixing members 107 are provided at the circular perforations of the seal 103. The cross-section of the second fixing members 107 is circular. The second fixing members 107 are slidably connected to the seal 103 at the circular perforations of the seal 103. A hole is penetrated through the central part of the seal 103 at the position corresponding to the central part of the cage 102. The hole is a circular hole. A connecting rod 200 extends from the cage 102 to the outside of the seal 103 through the circular hole of the seal 103. The cross-section of the connecting rod 200 is circular. The connecting member 202 is fixedly connected to the cage 102 inside the circular hole of the seal 103. Fixing rods 201 are symmetrically provided on the connecting rod 200. The cross-section of the fixing rods 201 is circular. The fixing rods 201 are fixedly connected to the connecting rod 200. Connecting members 202 are provided at positions of the fixing rods 201 corresponding to the second fixing members 107.Both ends of the connecting member 202 are fixedly connected to the fixing rod 201 and the second fixing member 107 respectively. The sealing member 103 can prevent the outflow of the grease, and the filling pipe 100 can be cleaned by removing the sealing member 103. The cooperation among the first fixing member 105, the second fixing member 107 and the spring telescopic rod 106 enables the connecting rod 200 to rebound when the cage body 102 is taken out of the filling pipe 100 after being pushed, so that the cage body 102 can be reset. The connecting rod 200 can make the connection between the spring telescopic rod 106 and the connecting rod 200 more stable.
[0020] The utility model can, through the design of the spring telescopic rod 106 and the corresponding fixing members and connecting members 202 in the sealing member 103, allow users to adjust the position or force of the components according to actual needs, so as to adapt to different types of electrical equipment and different filling environments. Moreover, the overall structure is compact, the cooperation among components is tight, and unnecessary operation steps and time waste are reduced.
[0021] As Figure 2 shown, first handles 203 are symmetrically arranged on the outer side of the filling pipe 100. The cross-section of the first handle 203 is rectangular. The first handle 203 is at the symmetrical position on the outer side of the filling pipe 100 and is fixedly connected to the filling pipe 100 on the outer side of the filling pipe 100. The first handle 203 is used for auxiliary support, so that the staff can hold and operate more stably during use, and avoid the grease not being applied to the predetermined lubrication points due to instability during use.
[0022] As Figures 1-2 shown, a hole penetrating through the pipe body is provided on the side surface of the filling pipe 100. The hole is a circular hole. A sealing plug 204 is connected at the circular hole. The cross-section of the sealing plug 204 is rectangular. A circular convex block fitting the circular hole is provided on the side of the sealing plug 204 close to the circular hole. The sealing plug 204 is fixedly connected to the filling pipe 100. This hole is used for filling the grease into the filling pipe 100, and it is closed by the sealing plug 204 to prevent the grease from flowing out.
[0023] As Figure 2 shown, a second handle 205 is provided on the side of the connecting rod 200 away from the fixing ring 101. The cross-section of the second handle 205 is rectangular. The second handle 205 is fixedly connected to the connecting rod 200 on the connecting rod 200. By connecting with the connecting rod 200, the second handle 205 can directly push the cage body 102 on the connecting rod 200 to extend out of the filling pipe 100, and this part enables the operator to push the connecting rod 200 more conveniently.
[0024] Working principle: During use, first open the sealing plug, pour in the grease, then install and close the sealing plug. Align the cage body with the predetermined lubrication point, and push the second handle to extend the cage body out of the filling pipe. The space inside the cage body can carry out the grease and smear it. After one use, judge whether secondary smearing is needed by observing the situation of the lubrication point. And during use, the fixing ring can make the cage body fit with the fixing ring when the cage body extends out a short distance outward, preventing the excess grease from flowing out. When retracting, the grease can still be normally replenished in the cage body. After the filling device is used up, clean the filling pipe by opening the seal to prevent the residue of excess grease from causing blockage.
[0025] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0026] The above is the preferred implementation manner of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
