Description

Grease gun head for grease cartridge

Technical Field

The utility model relates to a grease gun head for grease shots, and belongs to the technical field of grease injectors.

Background

Grease guns are common tools for injecting lubricating grease, and grease in traditional grease guns is filled into gun barrels of the grease guns by hands, so that the grease guns are difficult to operate, dirty in hands and difficult to clean, and are time-consuming and labor-consuming. At present, butter bullets are adopted to be filled into gun barrels of butter guns, so that time and labor are saved, and hands are not dirty. As shown in fig. 5, the butter bullet 1 is a corrugated structure made of soft material and filled with butter; the oil outlet 2 of the butter bullet is provided with an external thread 3; when not in use, the oil outlet is sealed by an outer cover. As shown in fig. 5, one end of the main body 4 of the grease gun head is provided with an oil outlet 5, and the other end is provided with a gun barrel connecting part 6; an oil inlet 7 connected with a butter ejecting oil port is arranged at one end of the gun head main body, provided with a gun barrel connecting part, and an inner cavity wall of the oil inlet is provided with an inner thread 8 so as to be screwed with the butter ejecting oil port; and then connecting the gun head main body with the gun barrel.

However, the above structure has the following problems in use: when the butter bullet is connected with the gun head of the butter gun, the gun head is generally held by one hand, the butter bullet is held by the other hand, and then the screw thread screwing action is carried out by the slightly acting force of the two hands; as shown in FIG. 5, since the internal thread of the gun head oil inlet is fully distributed on the whole inner cavity wall, the grease ejecting port needs to be screwed when contacting with the outer end of the oil inlet, if the oil outlet and the oil inlet are not aligned, the screwing cannot be smoothly performed, and at the moment, the grease in the grease cartridge is easily pressed and extruded, so that the grease is remained or splashed in the oil inlet and the gun barrel, the grease is wasted, and the grease is difficult to clean.

Aiming at the problems, the structure of the grease gun head is improved, so that grease can be smoothly connected with the grease gun head.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art, and provides a grease gun head for a grease cartridge, which can be smoothly connected with a grease ejecting port, so that the waste of grease is reduced.

The technical scheme of the utility model is as follows:

the utility model provides a butter is grease gun rifle head for bullet, includes the rifle head main part, the one end of rifle head main part is equipped with the oil outlet, and the other end is equipped with gun barrel connecting portion, the rifle head main part is equipped with the oil inlet that links to each other with the butter popping out the hydraulic fluid port in the one end that sets up gun barrel connecting portion, characterized by, the inner chamber wall of oil inlet includes from inside to outside in proper order: the grease ejecting device comprises an internal thread section and a smooth inner wall section, wherein the internal thread section and the smooth inner wall section are connected with a grease ejecting port, and the length of the smooth inner wall section is smaller than that of the internal thread section.

By adopting the scheme, the inner cavity wall of the oil inlet of the gun head main body is divided into two sections (an inner thread section on the inner side and a smooth inner wall section on the outer side), the oil outlet of the butter bullet firstly enters the smooth inner wall section, and at the moment, the butter bullet is only required to be sent into the oil inlet without excessive force application, so that the butter bullet cannot be extruded by force to produce oil; and then, the butter ejecting oil port is screwed with the inner thread section of the oil inlet of the gun head main body, and if the butter is extruded under force, the butter cannot remain at the outer side end of the oil inlet and cannot pollute the gun barrel. According to the utility model, the internal thread of the oil inlet of the gun head is integrally moved inwards to flow out a part of the smooth inner wall, so that on one hand, the guiding of the butter ejecting oil port can be facilitated, and on the other hand, the problems of butter residue and splashing at the end part of the oil inlet and in the gun barrel after the butter bullet is pressed are solved.

Furthermore, the inner cavity of the oil inlet is provided with positioning rods inserted into the butter ejecting oil ports, and the positioning rods are arranged in pairs and symmetrically. When the gun head oil inlet is connected with the butter ejecting oil port, the locating rod is directly inserted into the inner cavity of the butter ejecting oil port, so that the butter ejecting oil port can be further guided, and the gun head oil inlet and the butter ejecting oil port are conveniently and smoothly connected. Because the butter bullet adopts soft material to make, the locating lever also can strengthen butter and pop out hydraulic fluid port intensity, prevents that it from receiving the compression deformation in the screw thread connects the process soon.

Furthermore, the locating rod is fixedly connected to the inner cavity wall of the oil inlet through a connecting rod, and the connecting rod can solve the installation problem of the locating rod; the length of connecting rod slightly is greater than butter and pops out the hydraulic fluid port wall thickness, and locating lever and connecting rod contained angle be 90, so the design can carry out spacing support to butter and pop out the hydraulic fluid port, prevents that it from being compressed and warp, keeps the aperture of oil-out.

Further, the locating rod is axially arranged along the oil inlet from the inner side end of the oil inlet outwards, and the length of the locating rod is larger than the length of the internal thread section and smaller than the depth of the oil inlet. By means of the design, in the threaded screwing process, the locating rod can always provide oil port guiding and limiting support.

Further, the length of the internal thread section of the oil inlet is smaller than or equal to that of the external thread section of the butter ejecting port, and the depth of the oil inlet is smaller than or equal to that of the butter ejecting port. By the design, the whole internal thread section of the oil inlet can be guaranteed to be fully screwed with the butter ejecting oil port, and the connection firmness of the internal thread section and the butter ejecting oil port is guaranteed.
