Description

Technical Field

[0001] This utility model relates to the field of lubricating grease injection devices, and in particular to a grease gun. Background Technology

[0002] Grease guns are now a common tool for repairing and maintaining machinery. Common grease guns use compressed air to push a piston in the grease canister forward, supplying grease to the plunger pump at the nozzle. However, during use, this type of grease gun has a small grease output per unit time because lifting the plunger pump handle is the suction stroke and pressing it down is the injection stroke. This results in low grease output per unit time, making it difficult to quickly add grease, leading to low work efficiency and wasting time and effort. Most existing grease guns are cylindrical, which store a small amount of grease in the canister. When the machine requires a large amount of grease, the grease gun may run out of grease multiple times. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a grease gun that solves the issues of low working efficiency and the frequent occurrence of running out of grease.

[0004] The technical solution adopted by this utility model is as follows: a grease gun, including an oil dispensing device, an oil dispensing seat installed on the oil dispensing device, a first cavity inside the oil dispensing device, a second cavity inside the oil dispensing seat, the first cavity and the second cavity being connected, an oil outlet on the oil dispensing seat, and also including a button, a push rod, and a first elastic element. The button is fixedly connected to the push rod, the push rod is slidably connected within the second cavity, the button is sleeved on the end of the oil dispensing seat, the button is slidably connected to the oil dispensing seat, the first elastic element connects the button and the oil dispensing seat, and the button covers the first elastic element.

[0005] With the above technical solution, when the user uses the oiling device, he fills it with grease. The oiling device can squeeze the grease from the first cavity to the second cavity. Pressing the button causes the push rod to push the grease out of the oil outlet. The first elastic element can help the button reset. The oiling device will continue to squeeze the grease in the first cavity, which facilitates continuous oiling, improves the efficiency of oiling, and makes the oiling process more labor-saving.

[0006] Furthermore, the oil outlet seat is provided with a first step portion, which is connected to the first elastic member and is located on the second cavity.

[0007] With the above technical solution, the first elastic element is installed on the first step, making the installation of the first elastic element more stable and less likely to slip off.

[0008] Furthermore, the second cavity includes a first channel and a second channel, the push rod is slidably connected in the first channel, the first channel, the push rod, and the oil outlet are on the same straight line, the push rod and the oil outlet are respectively located at both ends of the first channel, and the second channel communicates with the first cavity.

[0009] With the above technical solution, the first channel, push rod, and oil outlet are on the same straight line, which makes the grease injection efficiency in the first channel higher.

[0010] Furthermore, the oil outlet seat is provided with a second step portion, the push rod includes a first segment and a second segment, the cross-section of the first segment is smaller than that of the second segment, the first segment is connected to the button, and the second step portion can limit the movement of the second segment.

[0011] Through the above technical solution, the second step can limit the second segment and prevent the push rod from detaching from the oil outlet seat.

[0012] Furthermore, the angle between the second channel and the push rod is an acute angle.

[0013] With the above technical solution, the angle between the second channel and the push rod is an acute angle, which allows the grease in the oil outlet device to slide along the second channel toward the oil outlet, making it easier for the push rod to push and inject oil.

[0014] Furthermore, the cross-sectional area of ​​the oil outlet is smaller than the cross-sectional area of ​​the first channel opening.

[0015] With the above technical solution, the grease in the second cavity will not flow out from the oil outlet due to atmospheric pressure when the button is not pressed.

[0016] Furthermore, the oil outlet seat is provided with a first arc-shaped portion and a second arc-shaped portion, and the openings of the first arc-shaped portion and the second arc-shaped portion face the oil outlet.

[0017] With the above technical solution, the user can hook the first and second arc-shaped parts with their index and middle fingers respectively, and press the button with their thumb to complete the oiling operation, so that the user can use the grease gun with one hand.

[0018] Furthermore, the oil outlet device includes a push plate, a connecting rod, a second elastic element, and a hard shell. The hard shell is made of a rigid material. The bottom of the oil outlet seat is provided with a first connection port, which communicates with the second channel. The hard shell is threadedly connected to the first connection port. The second elastic element connects the push plate and the oil outlet device, and the second elastic element pushes the push plate to slide toward the second channel.

[0019] Through the above technical solution, the second elastic element can continuously push the push plate to move the grease from the first cavity into the second cavity, which facilitates grease injection.

[0020] Furthermore, the oil outlet device includes a soft shell made of soft material, and the oil outlet seat is provided with a second connection port, which is connected to the second channel. The head of the soft shell is threadedly connected to the side wall of the second connection port.

[0021] By using the above technical solution, the soft shell is squeezed, and the grease inside the soft shell enters the first channel through the second channel, making it convenient for the user to inject grease. Attached Figure Description

The first elastic element 3 connects the button 4 and the grease dispensing seat 2, and the button 4 covers the first elastic element 3.

[0028] When using the device, the user fills the oiling device 1 with grease. The oiling device 1 can squeeze the grease from the first cavity 101 to the second cavity 206. Pressing the button 4 causes the push rod 5 to push the grease out of the oil outlet 201. The first elastic element 3 can help the button 4 to reset. The oiling device 1 will continue to squeeze the grease in the first cavity 101, which facilitates continuous oiling, improves the efficiency of oiling, and makes the oiling process more labor-saving.

[0029] The first elastic element 3 is preferably a spring.

[0030] See Figure 2 , Figure 3The oil outlet seat 2 is provided with a first step 202, which is connected to the first elastic member 3 and is located on the second cavity 206.

[0031] The first elastic element is installed on the first step 202, making the installation of the first elastic element 3 more stable and less likely to slip off.

[0032] See Figure 2 , Figure 3 The second cavity 206 includes a first channel 2061 and a second channel 2062. The push rod 5 is slidably connected in the first channel 2061. The first channel 2061, the push rod 5, and the oil outlet 201 are on the same straight line. The push rod 5 and the oil outlet 201 are located at the two ends of the first channel 2061, respectively. The second channel 2062 is connected to the first cavity 101.

[0033] The first channel 2061, push rod 5, and oil outlet 201 are on the same straight line, which makes the grease injection efficiency in the first channel 2061 higher.

[0034] See Figure 2 , Figure 3 The oil outlet seat 2 is provided with a second step 203. The push rod 5 includes a first segment 501 and a second segment 502. The cross-section of the first segment 501 is smaller than that of the second segment 502. The first segment 501 is connected to the button 4. The second step 203 can limit the second segment 502.

[0035] The second step 203 can limit the second section 502 to prevent the push rod 5 from detaching from the oil outlet seat 2.

[0036] See Figure 2 , Figure 3 The angle between the second channel 2062 and the push rod 5 is an acute angle.

[0037] The angle between the second channel 2062 and the push rod 5 is an acute angle, which allows the grease in the oiling device 1 to slide along the second channel 2062 toward the oil outlet 201, making it easier for the push rod 5 to push and inject grease.

[0038] See Figure 2 , Figure 3 The cross-sectional area of ​​the oil outlet 201 is smaller than the cross-sectional area of ​​the opening of the first channel 2061.

[0039] Without pressing button 4, the butter in the second cavity 206 will not flow out of the oil outlet 201 due to atmospheric pressure.

[0040] See Figure 1 , Figure 2 , Figure 3The oil outlet seat 2 is provided with a first arc-shaped part 204 and a second arc-shaped part 205, and the openings of the first arc-shaped part 204 and the second arc-shaped part 205 face the oil outlet 201.

[0041] The user can hook the first arc-shaped part 204 and the second arc-shaped part 205 with their index and middle fingers respectively, and press the button 4 with their thumb to complete the oiling operation, so that the user can use the grease gun with one hand.

[0042] Based on the different structures of the oil outlet device 1, it can be divided into Example 1 and Example 2; Example 1: See Figure 2 , Figure 4 The oil outlet device 1 includes a push plate 301, a connecting rod 302, a second elastic element 303, and a hard shell 304.

The hard shell 304 is threadedly connected to the first connection port 207. The second elastic element 303 connects the push plate 301 and the oil outlet device 1. The second elastic element 303 pushes the push plate 301 and slides towards the second channel 2062.

[0043] The second elastic element 303 can continuously push the pusher plate 301 to push the grease from the first cavity 101 into the second cavity 206, which facilitates grease injection.

[0044] Due to atmospheric pressure and the viscosity of butter, the second elastic element 303 will not squeeze the butter out of the oil outlet 201.

[0045] The second elastic element 303 is preferably a spring.

[0046] Example 2: See Figure 3 , Figure 4 The oil outlet device 1 includes a soft shell 305, which is made of soft material.
