Description

Technical Field

[0001] The present application relates to the field of electric wrenches, and in particular to a handheld lithium-ion electric wrench. Background Art

[0002] Lithium-ion battery-powered torque wrenches are widely used in many fields, including automotive manufacturing, machining, aerospace, and construction. They improve work efficiency and quality, ensuring bolts and nuts receive the correct torque and avoiding over- or under-tightening. Lithium-ion battery torque wrenches generally have the following features: Electric torque adjustment: Lithium-ion battery torque wrenches apply torque via an electric drive system, allowing the desired torque value to be selected by adjusting a button or switch. This ensures accurate torque is applied to the bolt or nut. Accuracy and consistency: Lithium-ion battery torque wrenches typically offer high accuracy and consistency, delivering accurate torque within the set torque range. This is crucial for tasks requiring precise torque control, such as automotive repair and mechanical assembly. Portability: Due to their lithium-ion battery power, lithium-ion battery torque wrenches are typically small and lightweight, making them easy to carry and operate. This makes them suitable for use in various locations or workspaces. Efficiency: Lithium-ion battery torque wrenches provide fast and efficient torque application, significantly reducing work time and labor intensity compared to manual wrenches.

[0003] Existing lithium-ion battery wrenches generate a lot of heat during actual use, and most electric wrenches on the market dissipate heat directly through the heat dissipation holes on the shell. This passive heat dissipation method will result in poor heat dissipation effect of the wrench, thus directly affecting the service life of the electric wrench. Utility Model Content

[0004] In order to solve the problem of poor heat dissipation effect of existing electric wrenches when used, the present application provides a handheld lithium-powered wrench.

[0005] The present application provides a handheld lithium battery wrench that adopts the following technical solution:

[0016] The outer wall of the installation rod is sleeved with a spring, and the inner wall of the cleaning box is installed with a driving component.

[0017] By adopting the above technical solution, the rack is conveniently supported by the spring on the mounting rod, and the arrangement of the drive assembly facilitates the direct driving of the rack to move.

[0018] The driving assembly includes a driving tube fixedly connected to the inner wall of the cleaning box, and the inner wall of the driving tube is slidably connected to a driving column, one end of the driving column is fixedly connected to the rack, the other end of the driving column is fixedly connected to a magnet, and the inner wall of the driving tube is fixedly connected to an electromagnet.

[0019] By adopting the above technical solution, the electromagnet in the driving tube is energized to generate the same magnetism as the magnet. According to the principle of like charges repel each other, the driving column is directly driven to drive the rack to slide on the mounting rod.

[0020] One end of the shell body is rotatably connected with a clamp, and the outer wall of the bottom of the shell body is clamped with a lithium battery.

[0021] By adopting the above technical solution, the motor in the shell body is conveniently powered by the lithium battery, and the motor in the shell body directly drives the chuck to rotate when it is started.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application provides a filter mechanism on the housing body. The filter mechanism cooperates with the fan on the mounting base to accelerate the air flow in the housing body, thereby facilitating the heat dissipation of the electric wrench and solving the problem of poor heat dissipation during operation of existing electric wrenches.

[0024] 2. The present application sets a filtering mechanism on the shell body.

[0031] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0032] The embodiment of the present application discloses a handheld lithium-powered wrench.

[0033] Reference Figure 1-3 , a handheld lithium-ion wrench, comprising a housing assembly 1, and a filter mechanism 4 mounted on the housing assembly 1;

[0034] Reference Figure 1-2 The housing assembly 1 in the electric wrench includes a housing body 3, and a mounting opening is opened on the outer wall of the housing body 3, and the filter mechanism 4 is installed on the inner wall of the mounting opening. An air inlet is opened on the outer wall of the other side of the housing body 3, and the inner wall of the air inlet is fixedly connected to a mounting seat 6. A circular opening is opened on the outer wall of one side of the mounting seat 6, and a fan 7 is fixedly connected to the inner wall of the circular opening. A clamp 5 is rotatably connected to one end of the housing body 3, and a lithium battery 2 is clamped on the outer wall of the bottom of the housing body 3;

[0035] During use, by installing a fan 7 on the housing of the electric wrench, the fan 7 is started to accelerate the air flow in the housing. When the fan 7 draws out the air in the housing body 3, the outside air enters the housing body 3 after being filtered by the filter mechanism 4, thereby improving the heat dissipation efficiency of the electric wrench. The arrangement of the lithium battery 2 is convenient for powering the motor in the housing body 3. When the motor in the housing body 3 is started, it directly drives the chuck 5 to rotate.

[0036] Reference Figure 1-2 The filter mechanism 4 includes a filter box 8 fixedly connected to the inner wall of the installation port, and the cross-section of the filter box 8 is a trapezoidal structure. A connecting opening is opened on the outer wall of one side of the filter box 8, and a filter screen 9 is fixedly connected to the inner wall of the connecting opening. A cleaning component 10 is installed on the inner wall of the filter box 8, and a connecting port 11 is opened on the outer wall of the other side of the filter box 8.

[0037] During use, the cleaning assembly 10 in the filter box 8 is used to conveniently assist in cleaning impurities adhering to the filter screen 9, thereby preventing impurities from clogging the filter screen 9 and causing a decrease in the air intake volume.

[0038] Reference Figure 3-4, the cleaning assembly 10 for cleaning the filter screen 9 on the auxiliary filter box 8 includes a cleaning box 12 fixedly connected to the inner wall of the filter box 8, and a strip-shaped opening is opened on the outer wall of the bottom of the cleaning box 12. A rotating plate 13 that passes through the strip-shaped opening is rotatably connected to the inner wall of one side of the cleaning box 12, and one end of the rotating plate 13 is fixedly connected to a knock hammer 15, and one end of the transmission shaft of the rotating plate 13 is fixedly connected to a gear 14. The inner walls of both sides of the cleaning box 12 are fixedly connected to the same mounting rod 16, and the outer wall of the mounting rod 16 is slidably connected to a rack 18, the rack 18 and the gear 14 are meshed with each other, the outer wall of the mounting rod 16 is sleeved with a spring 17, and a driving assembly 19 is installed on the inner wall of the cleaning box 12.

[0039] During use, by rotating the rotating plate 13 installed in the cleaning box 12, the rotating plate 13 drives the knocking hammer 15 to impact the filter screen 9 when it rotates. When the knocking hammer 15 impacts the filter screen 9 and generates vibration, it is convenient to shake off the impurities adhering to the filter screen 9. The spring 17 on the mounting rod 16 facilitates the support of the rack 18. The setting of the drive assembly 19 facilitates the direct drive of the rack 18 to move. The setting of the mounting rod 16 facilitates the sliding installation of the rack 18. When the rack 18 slides, it is convenient to directly drive the gear 14 to rotate. When the gear 14 rotates, it is convenient to directly drive the rotating plate 13 to swing.

[0040] Reference Figure 4-5 The driving assembly 19 that assists the movement of the rack 18 includes a driving tube 20 fixedly connected to the inner wall of the cleaning box 12, and the inner wall of the driving tube 20 is slidably connected to a driving column 21, one end of the driving column 21 is fixedly connected to the rack 18, and the other end of the driving column 21 is fixedly connected to a magnet 22. The inner wall of the driving tube 20 is fixedly connected to an electromagnet 23. The electromagnet 23 in the driving tube 20 is energized to generate the same magnetism as the magnet 22. According to the principle of like charges repel each other, it is convenient to directly drive the driving column 21 to drive the rack 18 to slide on the mounting rod 16.

[0041] The implementation principle of a handheld lithium-ion wrench in the embodiment of the present application is as follows: when in use, after the lithium battery 2 is installed, the switch is pressed to start the motor in the shell body 3, thereby directly driving the chuck 5 to rotate, and at the same time the fan 7 on the mounting base 6 is started to extract the air in the shell body 3, and the outside air enters the shell after being filtered by the filter mechanism 4. During filtering, the filter screen 9 in the filter box 8 filters out impurities on the air. When the filter screen 9 needs to be cleaned, the electromagnet 23 in the driving assembly 19 is energized to generate the same magnetism as the magnet 22, so it is convenient to push the driving column 21 to push the rack 18 to move. When the rack 18 moves, it directly compresses the spring 17. When the rack 18 moves, it directly drives the gear 14 to rotate. When the electromagnet 23 is de-energized, the spring 17 drives the rack 18 to reset, thereby directly driving the rotating plate 13 to drive the knocking hammer 15 to impact the filter screen 9. When the knocking hammer 15 impacts the filter screen 9 and generates vibration, it is convenient to shake off the impurities adhering to it.
