Description

Technical Field

[0001] This application relates to the technical field of lubrication equipment, and in particular to a portable grease gun. Background Technology

[0002] A grease gun is a tool used to inject grease into the lubrication points of mechanical equipment. Its main purpose is to apply grease accurately to the parts that need lubrication through pressure, thereby reducing friction and wear and extending the service life of the equipment. Grease guns are widely used in many fields such as automotive repair, agricultural equipment, factory systems, and gardening equipment.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN201934880U, which discloses a grease gun, including a grease reservoir and a grease nozzle. The grease reservoir contains a piston that pushes grease, and the piston and the front end of the grease reservoir form a grease storage chamber. The grease gun also includes a first plunger pump and a second plunger pump. The first plunger pump includes a first cylinder and a first plunger slidably disposed in the first cylinder. The second plunger pump includes a second cylinder and a second plunger slidably disposed in the second cylinder. The first and second plungers are linked by a connecting member to achieve reverse movement within the first and second cylinders. The first and second cylinders are connected to the grease storage chamber through a first channel and a second channel, respectively. Both the first and second cylinders are connected to the grease nozzle.

[0004] However, in actual use, to ensure that the grease gun can lubricate various parts of mechanical equipment, the nozzle of the grease gun is usually made of a flexible hose. This design means that the user not only needs to hold and secure the grease gun's reservoir but also the nozzle to prevent it from falling off. Since a user only has two hands, the hand used to hold the reservoir usually also needs to operate the handle to dispense grease, making operation very inconvenient. Utility Model Content

[0005] To improve the stability of grease guns during use, this application provides a portable grease gun.

[0006] This application provides a portable grease gun, which adopts the following technical solution:

[0007] A portable grease gun includes a barrel and a piston assembly mounted on the barrel. A connecting rod handle is rotatably mounted on the piston assembly. Under the action of the connecting rod handle, the piston assembly squeezes grease out of the barrel. A stabilizing plate is mounted on the barrel, and four through holes for the user's fingers to pass through are provided on the stabilizing plate. An installation mechanism is provided at the grease outlet of the barrel, and a grease nozzle is detachably mounted on the barrel through the installation mechanism.

[0008] By adopting the above technical solution, a stabilizing plate with through holes is installed on the cylinder. The user can stabilize the cylinder by inserting their finger into the through hole of the stabilizing plate, without having to hold the cylinder with their whole hand. The extra space in the hand can be used to use the connecting rod handle to squeeze the grease, which greatly improves the convenience of the user when using the grease gun. The cylinder position can be stabilized with only a single finger. The structure is simple, convenient and practical.

[0009] Optionally, the mounting mechanism includes:

[0010] The mounting block is disposed on the cylinder body and is hollow inside. The mounting block is connected to the oil outlet.

[0011] The mounting sleeve is rotatably fitted onto the mounting block;

[0012] The first oil outlet pipe is installed on the mounting sleeve. The axial direction of the first oil outlet pipe is parallel to the axial direction of the cylinder. The first oil outlet pipe is connected to the inside of the mounting block.

[0013] The second oil outlet pipe is installed on the mounting sleeve. The axial direction of the second oil outlet pipe is perpendicular to the axial direction of the cylinder. The second oil outlet pipe is connected to the inside of the mounting block.

[0014] The mounting nut is disposed on the first oil outlet pipe and the second oil outlet pipe, and the oil outlet nozzle has a thread at its end, and the oil outlet nozzle is threadedly connected to the mounting nut.

[0015] A limiting component is disposed on the mounting block and is used to limit the rotational position of the mounting sleeve.

[0016] By adopting the above technical solution, an installation block is installed on the cylinder, and an installation sleeve is rotated on the installation block. After unlocking the limiting component, the position of the first oil outlet pipe and the second oil outlet pipe can be adjusted by rotating the installation sleeve, so that the position of the oil nozzle on the first oil outlet pipe and the second oil outlet pipe can meet the needs of refueling work, greatly improving the ease of use of the grease gun.

[0018] A limiting toothed ring is provided on the mounting sleeve;

[0019] A limiting spring is provided on the mounting block;

[0020] A limiting block is provided on a limiting spring, and the limiting block engages with a limiting toothed ring under the action of the limiting spring.

[0021] By adopting the above technical solution, the moving limit block squeezes the limit spring to move, causing the limit block to disengage from the limit gear ring. This allows the installation sleeve to be rotated freely to adjust the position of the oil outlet. After adjustment, the limit block is released, allowing it to engage with the limit gear ring under the action of the limit spring, thus completing the position limiting work of the limit gear ring.

[0022] Optionally, the oil outlet includes a base tube, a conduit, and a nozzle. The base tube has threads and is threaded to a mounting nut. The conduit is mounted on the base tube, and the nozzle is mounted on the conduit. The conduit can be either a rigid tube or a flexible tube.

[0023] By adopting the above technical solution, the grease gun is configured as a combination of a base tube, a guide tube, and a nozzle. By configuring the guide tube into both rigid and flexible forms, users can choose to connect either a rigid or flexible grease gun according to their actual work needs, greatly improving the adaptability of the grease gun to different working environments.

[0024] Optionally, a connecting pipe is provided at the end of the conduit away from the base pipe, the connecting pipe is threaded, the nozzle is provided with a threaded hole, and the connecting pipe is threadedly connected to the threaded hole in the nozzle.

[0025] By adopting the above technical solution, the guide tube and the nozzle are detachably connected by connecting the threaded hole in the nozzle through the connecting pipe. This allows the guide tube or nozzle on the oil outlet to be replaced separately, making the oil outlet more applicable and reducing maintenance and replacement costs.

[0026] Optionally, the corners of the side of the linkage handle that contacts the user's hand are provided with rounded chamfers.

[0027] By adopting the above technical solution, rounded chamfers are made at the corners of the surface of the linkage handle that contacts the user's hand, which greatly improves the user's comfort when holding the linkage handle.

[0028] Optionally, the mounting block is provided with a clamping block, and the clamping block has a clamping groove. When the conduit is a flexible tube, the clamping block clamps and fixes the conduit through the clamping groove.

[0029] By adopting the above technical solution, a clamping block that can hold the soft conduit is installed on the mounting block. When the soft conduit is not in use, the conduit can be clamped and fixed by the clamping block, so that the conduit will not swing around and it is convenient for users to use or carry.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By installing a stabilizing plate with through holes on the cylinder, the user can stabilize the cylinder by inserting their fingers into the through holes of the stabilizing plate, without having to hold the cylinder with their whole hand. The extra space in the hand can be used to operate the connecting rod handle to squeeze the grease, which greatly improves the convenience of the user when using the grease gun. The cylinder position can be stabilized with just one finger. The structure is simple, convenient and practical.

[0032] 2. By installing an installation block on the cylinder and rotating the installation sleeve on the installation block, the position of the first oil outlet pipe and the second oil outlet pipe can be adjusted by rotating the installation sleeve after unlocking the limiting component. This allows the position of the oil nozzles on the first and second oil outlet pipes to meet the refueling requirements, greatly improving the ease of use of the grease gun.

[0038] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0039] This application discloses a portable grease gun.

[0040] Reference Figure 1The portable grease gun includes a barrel 1 and a piston assembly 11 mounted on the barrel 1. A connecting rod handle 12 is rotatably mounted on the piston assembly 11, and the piston assembly 11, under the action of the connecting rod handle 12, squeezes the grease out of the barrel 1. A stabilizing plate 13 is fixedly mounted on the outer wall of the barrel 1, and the stabilizing plate 13 has four through holes 14 for the user's fingers to pass through. A mounting mechanism 2 is provided at the grease outlet of the barrel 1, and a grease nozzle 15 is detachably mounted on the barrel 1 through the mounting mechanism 2.

[0041] Reference Figure 1 and Figure 2 The installation mechanism 2 includes an installation block 21, an installation sleeve 22, a first oil outlet pipe 23, a second oil outlet pipe 24, an installation nut 25, and a limiting component 26. The installation block 21 is fixedly installed at the oil outlet end of the cylinder 1. The installation block 21 is hollow and communicates with the oil outlet. The installation sleeve 22 is rotatably installed on the upper surface of the installation block 21. Both the first oil outlet pipe 23 and the second oil outlet pipe 24 are fixedly installed on the installation sleeve 22. The first oil outlet pipe 23 is fixedly installed on the top of the installation block 21 and communicates with the interior of the installation block 21. The second oil outlet pipe 24 is fixedly installed on the outer wall of the second oil outlet pipe 24 and communicates with the interior of the installation block 21. The axial direction of the first oil outlet pipe 23 is parallel to the axial direction of the cylinder 1. The axial direction of the second oil outlet pipe 24 is perpendicular to the axial direction of the cylinder 1. The installation nut 25 is fixedly installed on the end of the first oil outlet pipe 23 and the second oil outlet pipe 24 away from the installation block 21, and the oil outlet nozzle 15 is connected to the installation nut 25. The limiting component 26 is disposed on the mounting block 21 and is used to limit the rotational position of the mounting sleeve 22.

[0042] Reference Figure 1 and Figure 2 The grease gun nozzle 15 consists of a base tube 16, a guide tube 17, and a nozzle 18. The outer wall of the base tube 16 is threaded and threadedly connected to a mounting nut 25. The guide tube 17 is fixedly mounted on the base tube 16 and can be either a rigid tube or a flexible tube. Users can choose between the rigid or flexible guide tube 17 depending on their actual work needs, greatly improving the grease gun's adaptability to different working environments.

[0043] Reference Figure 2 and Figure 3 A connecting pipe 19 is fixedly installed on the end of the conduit 17 away from the base pipe 16. Threads are formed on the outer wall of the connecting pipe 19. A threaded hole is formed inside the nozzle 18, and the connecting pipe 19 is threadedly connected to the threaded hole inside the nozzle 18. The conduit 17 and the nozzle 18 are detachably connected by the threaded connection between the connecting pipe 19 and the threaded hole inside the nozzle 18. This allows for the individual replacement of either the conduit 17 or the nozzle 18 on the oil outlet 15, broadening the applicability of the oil outlet 15 and reducing maintenance and replacement costs.

[0044] Reference Figure 2 and Figure 3 The limiting assembly 26 includes a limiting gear ring 27, a limiting spring 28, and a limiting block 29. The limiting gear ring 27 is fixedly mounted on the outer wall of the mounting sleeve 22. The limiting spring 28 is fixedly mounted on the upper surface of the mounting block 21. The limiting block 29 is fixedly mounted on the end of the limiting spring 28 near the limiting gear ring 27.

When the conduit 17 is a flexible tube, the clamping block 32 clamps and fixes the conduit 17 through the clamping groove 33. Thus, when the flexible conduit 17 is not in use, the conduit 17 can be clamped and fixed by the clamping block 32, so that the conduit 17 will not swing around, making it convenient for users to use or carry.

[0048] The working principle of this application embodiment is as follows:

[0049] By installing a stabilizing plate 13 with a through hole 14 on the cylinder 1, the user can stabilize the cylinder 1 by inserting their finger into the through hole 14 of the stabilizing plate 13, without having to hold the cylinder 1 with their whole hand. The extra space in the hand can be used to squeeze the grease using the connecting rod handle 12, which greatly improves the convenience of the user when using the grease gun. The position of the cylinder 1 can be stabilized with just a single finger. The structure is simple, convenient and practical.

[0050] The movable limiting block 29 presses the limiting spring 28 to move, causing the limiting block 29 to disengage from the limiting tooth ring 27. This allows the mounting sleeve 22 to be rotated freely to adjust the position of the oil nozzle 15. As a result, the positions of the oil nozzles 15 on the first oil outlet pipe 23 and the second oil outlet pipe 24 can meet the needs of oiling work, greatly improving the ease of use of the grease gun.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
