Description

Technical Field

[0001] This utility model relates to the field of automatic grease injection technology, specifically an automatic grease injection device for automotive bracket bearings. Background Technology

[0002] The automatic grease injection device is a tool specifically designed for the lubrication and maintenance of automotive bracket bearings. It aims to improve the efficiency and precision of lubrication operations. This device achieves precise grease injection through automation technology, solving the problems of low efficiency and poor consistency in traditional manual grease injection methods. Its core functions include quantitative grease injection, pressure adjustment, and ease of operation. It is suitable for various scenarios such as automotive repair and production line assembly, and can effectively extend the service life of bearings and improve maintenance quality.

[0003] However, it still has some drawbacks. For example, the bearing grease injection device used in car brackets lacks a heating function for low-temperature environments, resulting in excessively high viscosity and poor fluidity of the grease in winter, which can easily cause blockage of the discharge nozzle and affect the grease injection efficiency. In addition, traditional heating methods are mostly whole-body heating, which consumes a lot of energy, is inconvenient to operate, and cannot flexibly start or stop the heating function according to actual needs, resulting in energy waste.

[0004] To address the aforementioned problems, this application proposes an automatic grease injection device for automotive bracket bearings. Utility Model Content

[0005] The purpose of this invention is to provide an automatic grease injection device for automotive bracket bearings, so as to solve the problem of easy material discharge blockage in automotive bearing grease injection devices in winter as mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic grease injection device for automotive bracket bearings, comprising a handheld automatic grease injection gun body, a grease cylinder fixedly connected to the top of the handheld automatic grease injection gun body, a functional frame fixedly connected to the front top of the grease cylinder, and rotating heating plates movable on both sides of the functional frame, with two sets of rotating heating plates. A heating copper tube assembly is fixedly connected inside the rotating heating plate. The rotating heating plate facilitates local heating of the end of the grease cylinder near the nozzle of the injection gun. In winter, local heating effectively improves the fluidity of the grease, significantly improving its performance. The viscosity of the heated grease decreases and its fluidity increases, making the discharge from the handheld automatic grease injection gun body smoother and preventing low-temperature blockage. Furthermore, the device adopts a quick-flip design, which cuts off the power after flipping open, allowing users to selectively use the heating function.

[0007] Preferably, an auxiliary lifting block is fixedly connected to one side of the rotating heating plate, a filling cover is installed at the rear end of the grease cylinder, an excess material observation port is installed above the grease cylinder, and a handle is fixedly connected to the lower part of the handheld automatic grease gun body.

[0008] Preferably, the handheld automatic grease gun body has a discharge nozzle fixedly connected to the front, a battery base detachably connected to the bottom of the handle, an anti-slip layer fixedly connected to the front of the handle, a trigger installed on the top of the front of the handle, a front handle fixedly connected to the bottom of the front of the handheld automatic grease gun body, and a small light fixedly connected to the front of the handheld automatic grease gun body.

[0009] Preferably, the functional frame has heating grooves inside both parts, and the functional frame has two sets. One side of the rotating heating plate is detachable inside the heating groove. An inner material cylinder is installed inside the heating groove. The inner material cylinder is fixedly connected to the front of the lubricating grease cylinder. The heating copper tube assembly is interconnected with the heating groove.

[0010] Preferably, the rotating heating plate has an electrical connection groove on one side, and a detachable extrusion contact piece is installed inside the electrical connection groove. The extrusion contact piece is installed on the inner wall of one side of the heating groove, and one side of the extrusion contact piece is fixedly connected to a linkage metal plate.

[0011] Preferably, a power supply contact is fixedly connected below the linkage metal plate. The linkage metal plate moves within the functional frame. A reset damping spring device is installed on one side of the linkage metal plate, and the reset damping spring device is installed inside the functional frame. When using the rotating heating plate, the device is in a low-temperature environment. The user can use the auxiliary lifting block to flip the two sets of rotating heating plates inward and close them, so that their electrical contact grooves are in close contact with the extrusion contact plates in the heating groove. At this time, the linkage metal plate is compressed and connected to the power supply contact through the power supply contact. The heating copper tube assembly starts to work and locally heats the grease in the inner barrel, thereby reducing its viscosity and improving its fluidity. When heating is complete or heating is no longer needed, the rotating heating plate is flipped outward by the auxiliary lifting block to remove it from the heating groove. The reset damping spring device pushes the linkage metal plate back to its original position, and the extrusion contact plates leave the electrical contact groove, automatically cutting off the power and stopping heating. This achieves the control of heating when closed and stopping when opened, effectively solving the problem of material blockage caused by poor grease fluidity in low-temperature environments. Compared with the prior art, the beneficial effects of this utility model are: This invention features a rotating heating plate that allows for localized heating of the end of the grease cylinder near the nozzle. In winter, this localized heating effectively improves the fluidity of the grease, significantly enhancing its performance. The heated grease has reduced viscosity and increased fluidity, resulting in smoother dispensing from the handheld automatic grease gun and preventing low-temperature blockage. Furthermore, the design incorporates a quick-flip mechanism that cuts off power when flipped open, allowing users to selectively use the heating function. Attached Figure Description

[0016] In this embodiment, as shown Figures 3-4As shown, the power connection slot 62 is formed on one side surface of the rotating heating plate 6. The extrusion contact piece 8 is detachably placed inside the power connection slot 62. The extrusion contact piece 8 is installed on the inner wall of one side of the heating tank 11. The linkage metal piece 81 is fixedly connected to one side of the extrusion contact piece 8. The power supply contact 83 is fixed below the linkage metal piece 81. The linkage metal piece 81 remains movable inside the functional frame 5. The reset damping spring device 82 is installed on one side of the linkage metal piece 81 and located inside the functional frame 5. When using the rotating heating plate 6, the device is in a low-temperature environment. The user can use the auxiliary lifting block 61 to flip the two sets of rotating heating plates 6 inward and close them to connect to electricity. The groove 62 is in close contact with the extrusion contact piece 8 in the heating groove 11. At this time, the linkage metal piece 81 is pressed and connected to the power supply through the power supply contact 83.

The viscosity of the heated grease decreases, and its fluidity increases, making the discharge from the handheld automatic grease gun body 1 smoother and preventing low-temperature blockage. The device also features a quick-flip design, which cuts off the power after flipping open, allowing users to selectively use the heating function.
