Technical Field
[0001] This utility model relates to the field of grease gun nozzle technology, and in particular to a quick-assembly and disassembly grease gun nozzle structure. Background Technology
[0002] Grease guns are manual tools used for lubricating mechanical equipment. Different mechanical parts may require different shaped nozzles. The efficiency of disassembling and assembling the nozzle directly affects the ease of operation. Therefore, a quick-disassembly and assembly grease gun nozzle structure is used.
[0003] To address this, patent CN209213432U discloses a grease gun nozzle, relating to the field of grease guns. It comprises a grease gun body, a nozzle head, a handle, a delivery tube, a nozzle base, and a nozzle. The nozzle head is mounted on the upper end of the grease gun body. A handle is screwed to one end of the nozzle head, and the other end of the nozzle head is connected to the delivery tube. The nozzle base is mounted on the delivery tube, and the nozzle is mounted on the nozzle base. The upper end of the nozzle base has an internal thread, and the lower end of the nozzle has an external thread that screws into the internal thread of the upper end of the nozzle base. Its structure is reasonable, easy to install, and convenient to use. The nozzle and nozzle base adopt a separate structure design, which not only facilitates easy replacement of the nozzle but also reduces the scrap rate and greatly improves the utilization rate of the nozzle base.
[0004] The grease gun tip mentioned above has a separate design for the tip and the tip base. This design not only makes it easy to replace the tip at any time, but also reduces the scrap rate and greatly improves the utilization rate of the tip base. However, because it is inconvenient to disassemble, it is time-consuming and laborious to replace the gun head, which makes it less applicable in use. Utility Model Content
[0005] The purpose of this invention is to provide a quick-disassembly and assembly grease gun nozzle structure to solve the problem of inconvenient disassembly of existing grease gun nozzle structures.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick-disassembly and assembly grease gun head structure, including a gun body;
[0007] An oil outlet is fixed at one end inside the gun body. A disassembly structure is fixed on the outer wall of the gun body at the oil outlet end. The disassembly structure includes a connecting seat fixed to one end of the gun body. A sleeve is fitted on the outer side of one end of the connecting seat. A return spring is fitted on the outer side of the connecting seat inside the sleeve. Movable grooves are evenly penetrated inside one end of the connecting seat. Limit beads are provided inside each movable groove.
[0008] The disassembly structure contains a gun head body;
[0009] A sealing structure is provided on the outer side of one end of the gun head body.
[0010] When using this device, the detachable structure facilitates easy replacement of the nozzle body, thereby improving the applicability of the grease gun nozzle structure during use; the sealing structure facilitates leak prevention, thereby improving the sealing performance of the grease gun nozzle structure during use.
[0011] Preferably, a limiting ring is fixed to the outer side of one end of the connecting seat, and a slot is provided inside the gun head body on one side of the limiting bead.
[0012] Preferably, the sleeve and the connecting seat form a sliding structure, and anti-slip strips are uniformly fixed on the outer side of the sleeve. The limiting ring prevents the sleeve from detaching from the connecting seat, and the anti-slip strips increase the friction between the palm and the sleeve.
[0013] Preferably, the limiting bead and the gun head body form an engaging structure through a slot. Under the elastic force of the return spring, the sleeve continuously pushes the limiting bead into the slot, thereby fixing the connecting seat and the gun head body together. When disassembly is required, the sleeve is moved by the anti-slip strip, pulling the gun head body to move the limiting bead into the movable slot, thereby separating the gun head body from the connecting seat.
[0014] Preferably, one end of the gun head body extends to the outside of the sleeve, and the gun head body and the connecting seat form a sliding structure.
[0015] Preferably, the sealing structure includes a sealing ring, a mounting groove, and a cavity. The mounting groove is located on the outer side of one end of the nozzle body, and the sealing ring is disposed inside the mounting groove. The sealing ring also contains a cavity. The mounting groove engages and secures the sealing ring with the oil outlet, while the cavity compresses and deforms the sealing ring.
[0016] Preferably, the sealing ring and the nozzle body form an engaging structure through a mounting groove, with the outer side of the sealing ring contacting the inner side of the connecting seat. The sealing ring enhances the seal between the nozzle body and the connecting seat, preventing grease leakage.
[0017] The present invention provides a quick-assembly and disassembly grease gun head structure, the advantages of which are:
[0018] By incorporating a disassembly structure, the limiting ring prevents the sleeve from detaching from the connecting seat. The anti-slip strip increases the friction between the palm and the sleeve. The return spring ensures that the sleeve continuously pushes the limiting bead into the slot, thus fixing the connecting seat and the nozzle body together. When disassembly is required, the sleeve is moved by the anti-slip strip, pulling the nozzle body and moving the limiting bead into the movable slot, thereby separating the nozzle body from the connecting seat. This device facilitates the replacement of the nozzle body, thereby improving the applicability of the grease gun nozzle structure in use.
[0019] By incorporating a sealing structure, the sealing ring and the oil outlet are interlocked and fixed by the mounting groove. The sealing ring is deformed and compressed by the cavity, which enhances the sealing between the nozzle body and the connecting seat, preventing grease leakage. This device facilitates leak prevention and improves the sealing performance of the grease gun nozzle structure during use. Attached Figure Description

A disassembly structure 2 is fixed on the outer wall of the gun body 1 at the oil outlet 4 end. The disassembly structure 2 includes a connecting seat 201 fixed to one end of the gun body 1. A sleeve 202 is sleeved on the outer side of one end of the connecting seat 201. A return spring 203 is sleeved on the outer side of the connecting seat 201 inside the sleeve 202. Movable grooves 207 are uniformly penetrated inside one end of the connecting seat 201. Limiting beads 205 are provided inside each of the movable grooves 207. A limiting ring 204 is fixed on the outer side of one end of the connecting seat 201. A slot 206 is opened inside the gun head body 3 on one side of the limiting bead 205. The sleeve 202 and the connecting seat 201 form a sliding structure. Anti-slip strips are uniformly fixed on the outer side of the sleeve 202. The limiting bead 205 and the gun head body 3 form a locking structure through the slot 206.
[0028] Reference Figure 2 and Figure 3 As shown, the anti-slip strip increases the friction between the palm and the sleeve 202. The limiting ring 204 prevents the sleeve 202 from separating from the connecting seat 201. The sleeve 202 is moved by the anti-slip strip, causing the gun head body 3 to move into the connecting seat 201. Under the elastic force of the return spring 203, the sleeve 202 pushes the limiting bead 205 into the slot 206, thereby fixing the connecting seat 201 and the gun head body 3 together. When disassembly is required, the sleeve 202 is moved by the anti-slip strip, pulling the gun head body 3 and causing the limiting bead 205 to move into the movable slot 207, thereby separating the gun head body 3 from the connecting seat 201.
[0029] The disassembly structure 2 has a gun head body 3 inside. A sealing structure 5 is provided on the outer side of one end of the gun head body 3. The sealing structure 5 includes a sealing ring 501, a mounting groove 502 and a cavity 503. The mounting groove 502 is opened on the outer side of one end of the gun head body 3. The sealing ring 501 is provided inside the mounting groove 502. The cavity 503 is provided inside the sealing ring 501. The sealing ring 501 and the gun head body 3 form an engaging structure through the mounting groove 502. The outer side of the sealing ring 501 contacts the inner side of the connecting seat 201. One end of the gun head body 3 extends to the outside of the sleeve 202. The gun head body 3 and the connecting seat 201 form a sliding structure.
[0030] Reference Figure 3 and Figure 4As shown, under the action of the mounting groove 502, the sealing ring 501 and the oil outlet 4 are locked together. When the gun head body 3 moves the sealing ring 501 into the interior of the connecting seat 201, the sealing ring 501 will be squeezed. Under the action of the cavity 503, the sealing ring 501 will be deformed and compressed. Under the action of the sealing ring 501, the sealing performance between the gun head body 3 and the connecting seat 201 is enhanced, preventing grease leakage.
