Background

The flat nozzle of the grease gun belongs to a connecting piece arranged on the grease gun and is used for being connected with an oil filling port. The flat nozzle of the grease gun is connected with the oil filling port through a clamping structure at the front end of the flat nozzle, and the grease gun is used for filling grease into the oil filling port.

The Chinese patent publication No. CN212719136U discloses a grease gun flat nozzle, which comprises a main body with a grease channel, a claw component arranged at the front end of the main body and used for sealing and clamping the grease nozzle, a sliding sleeve capable of axially moving and circumferentially rotating relative to the main body, a return spring arranged between the main body and the sliding sleeve and a handle, wherein the outer wall of the main body forms a tooth section, the tooth section comprises a plurality of teeth extending circumferentially for one circle, and the handle is provided with a round tooth part matched with the tooth section.

(1) Although the sliding sleeve is designed to move axially and rotate circumferentially relative to the main body, in practical application, in order to enable the claw component to provide stable and reliable clamping force to clamp the oil filling nozzle, the elastic modulus of the return spring is large, and the sliding sleeve cannot be easily rotated relative to the main body in practical application of the oil gun flat nozzle based on the large elastic modulus of the return spring. Therefore, the rotating design of the sliding sleeve relative to the main body belongs to redundant design, only the production cost of the flat nozzle of the grease gun can be increased, the production efficiency is reduced, and the practical application value is avoided.

(2) In order to realize the axial movement and circumferential rotation of the sliding sleeve relative to the main body, a plurality of circumferentially extending toothed parts are designed on the main body, and correspondingly, round toothed parts are arranged on the handle, and the sliding sleeve is axially moved relative to the main body through the engagement and disengagement of the round toothed parts and the plurality of circumferentially extending toothed parts.

However, in the process of clamping and loosening the claw component of the flat nozzle of the grease gun, the required axial stroke is short, and although a plurality of circumferentially extending teeth and round teeth can provide a longer stroke in the process of meshing and disengaging, the longer stroke belongs to redundant and invalid designs, only the production cost of the flat nozzle of the grease gun is increased, the production efficiency is reduced, and the practical application value is not realized.

(3) Only set up a handle, when pressing the handle, can produce the motion trend that changes sliding sleeve and main part axiality, lead to the resistance to increase, the atress is uneven, presses the required dynamics of handle great, experiences relatively poor. In addition, the sealing performance of the flat nozzle of the grease gun can be influenced due to uneven long-term stress, and the using handle is reduced.
