Description

Technical Field

[0001] This utility model relates to the field of electric wrench technology, specifically to a long-distance remote-controlled electric wrench. Background Technology

[0002] An electric wrench is a power tool used for tightening and loosening bolts and nuts. It is widely used in steel structure bridges, factory construction, chemical industry, power generation equipment installation, and other fields. It can automatically control torque and is suitable for projects requiring high-strength bolt connections, such as large steel towers, steel structure factories, and metallurgical equipment frames. Electric wrenches have advantages such as low power consumption, low noise, flexible adjustment, automatic stop, and stable torque. When tightening or loosening bolts or nuts in dangerous or hard-to-reach locations, remote-controlled electric wrenches are generally used.

[0003] When an electric wrench is in operation, the internal motor and other electronic components generate heat. If this heat cannot be dissipated in time, the temperature of the electric wrench will rise, affecting its performance and lifespan. Current technology generally involves setting up ventilation openings to utilize air convection for natural heat dissipation, or using forced cooling methods, such as installing fans or heat sinks. To prevent dust from entering the device, filters are usually installed to filter the incoming air. However, with long-term use, the filter pores will become clogged with dust or debris, which will affect the heat dissipation effect and thus reduce the lifespan of the device. Utility Model Content

[0004] This invention proposes a long-distance remote-controlled electric wrench, which solves the problem in existing electric wrenches where the filter holes become clogged with dust or debris after long-term use, affecting heat dissipation and thus reducing the lifespan of the device.

[0005] The technical solution of this utility model is as follows: a long-distance remote control electric wrench, including a long rod and a wireless remote control, a sleeve rod is slidably connected to the outside of the long rod, a connector is installed on the top of the sleeve rod, an electric wrench is provided on the right side of the connector, a heat dissipation mechanism is provided inside the electric wrench, and an adjustment mechanism is provided on the outside of the sleeve rod.

[0006] The heat dissipation mechanism includes a filter screen, a mounting plate, and baffles. The filter screen is fixedly connected to the left side of the electric wrench on its outer side. The mounting plate is fixedly connected to the inside of the electric wrench on its outer side. Several baffles are rotatably connected to both the front and rear sides of the electric wrench. A fan is installed inside the mounting plate. A reciprocating screw is fixedly connected to the left side of the fan. A threaded sleeve is threadedly connected to the outer circumference of the fan. Two guide rods are fixedly connected to the left side of the mounting plate, located above and below the reciprocating screw. A slider is slidably connected to the outer side of each of the two guide rods. A T-shaped rod is fixedly connected between the threaded sleeve and the two sliders respectively. A hammer is fixedly connected to the end of each of the two T-shaped rods away from the fan. A limit block is fixedly connected to the end of the reciprocating screw and the guide rods away from the mounting plate.

[0007] Preferably, the electric wrench is equipped with a main control chip and a battery that supplies power to the main control chip, and the main control chip is wirelessly connected to the wireless remote control.

[0008] Preferably, the hammer abuts against the filter screen.

[0009] Preferably, the adjusting mechanism includes a housing and a spring. One side of the housing is fixedly connected to the outer periphery of the sleeve rod. One end of the spring is fixedly connected to the inner top wall of the sleeve rod, and the other end of the spring is fixedly connected to the top of the long rod. A plug rod is slidably connected inside the housing. A movable plate is fixedly connected to one side of the plug rod, and a second spring is sleeved on the other side of the plug rod.

[0010] Preferably, one end of the second spring is fixedly connected to the middle of the movable plate, and the other end of the second spring is fixedly connected to the inner wall of the outer shell.

[0011] Preferably, the outer side of the movable plate is slidably connected to the inside of the outer casing.

[0012] Preferably, one end of the insertion rod is arc-shaped, and the one end of the insertion rod passes through the sleeve rod and is slidably connected inside the long rod.

[0013] Preferably, a handle is fixedly connected to the side end of the insertion rod.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, external cold air is filtered through a filter and drawn into the wrench by a fan to cool its internal components. When the fan is working, it drives the reciprocating screw to rotate, which in turn drives the threaded sleeve to move. This, in turn, drives the slider to slide outside the guide rod via the T-shaped rod, thereby driving the hammer to reciprocate to strike the filter. This avoids the problem of the filter being clogged with dust after long-term use, which would reduce the heat dissipation effect.

[0016] 2. In this utility model, by pulling down the long rod, since one end of the insertion rod is arc-shaped, the insertion rod will be squeezed as the long rod moves downward. The insertion rod being squeezed will drive the moving plate to move synchronously and squeeze the second spring. When it moves to the appropriate length, the second spring will push the moving plate to drive the insertion rod to reset and insert into the corresponding slot, thus completing the adjustment. This allows the electric wrench to adapt more flexibly to different operating spaces and requirements, making it easier to tighten or loosen bolts or nuts, improving work efficiency while ensuring operational safety.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-4 As shown, this embodiment proposes a long-distance remote-controlled electric wrench, including a long rod 1 and a wireless remote control 7. A sleeve rod 2 is slidably connected to the outside of the long rod 1. A connector 3 is installed on the top of the sleeve rod 2. An electric wrench 4 is provided on the right side of the connector 3. A heat dissipation mechanism 5 is provided inside the electric wrench 4. An adjustment mechanism 6 is provided on the outside of the sleeve rod 2.

[0028] The heat dissipation mechanism 5 includes a filter screen 51, a mounting plate 52, and baffles 53. The filter screen 51 is fixedly connected to the left side of the electric wrench 4 on the outside. The mounting plate 52 is fixedly connected to the inside of the electric wrench 4 on the outside. Several baffles 53 are rotatably connected to both the front and rear sides of the electric wrench 4. A fan 54 is installed inside the mounting plate 52. A reciprocating screw 55 is fixedly connected to the left side of the fan 54. A threaded sleeve 56 is threadedly connected to the outer circumference of the fan 54. Two guide rods 57 are fixedly connected to the left side of the mounting plate 52 and to the upper and lower sides of the reciprocating screw 55. A slider 58 is slidably connected to the outside of each of the two guide rods 57. T-shaped rods 59 are fixedly connected between the threaded sleeve 56 and the two sliders 58 respectively. A hammer 510 is fixedly connected to the end of each of the two T-shaped rods 59 away from the fan 54. A limit block 511 is fixedly connected to the end of the reciprocating screw 55 and the guide rods 57 away from the mounting plate 52.

[0029] The purpose of this setup is that, during use, the operator holds a long lever 1 in one hand and a wireless remote control 7 in the other. Using the long lever 1, the operator moves the electric wrench 4 to the top of the bolt requiring tightening. Then, the electric wrench 4 is aligned and clamped onto the bolt. The wireless remote control 7 is then activated (it should be noted that the wireless remote control 7 has a reverse switch, which allows for bolt removal when activated). The wireless remote control 7 transmits a signal to the main control chip on the electric wrench 4, which then activates the electric wrench 4 to tighten the bolt. If the bolt requiring tightening is at different angles, the wing nut on the connector 3 allows for multi-angle installation between the electric wrench 4 and the sleeve 2, adjusting the electric wrench 4 to the appropriate position. After adjusting the bolt tightening angle, clamp the electric wrench 4 onto the bolt to be tightened. Start the electric wrench 4 via the wireless remote control 7 to tighten the bolt. When heat dissipation is needed for the electric wrench 4, the fan 54 draws external cool air through the filter 51 and into the wrench to cool its internal components. During operation, the fan 54 drives the reciprocating screw 55 to rotate, which in turn moves the threaded sleeve 56. This movement, via the T-shaped rod 59, causes the slider 58 to slide outside the guide rod 57, thereby causing the hammer 510 to reciprocate and strike the filter 51. This prevents the filter 51 from becoming clogged with dust over long-term use, thus preventing reduced heat dissipation. Once the cool air has cooled down inside the wrench, it becomes hot air. At this point, open the baffle 53, and the hot air can be smoothly discharged through the vent, completing the entire heat dissipation cycle and ensuring the electric wrench 4 can operate continuously and stably.

[0030] Preferably, the electric wrench 4 has a main control chip and a battery that powers the main control chip. The main control chip is also wirelessly connected to the wireless remote control 7. The purpose of this arrangement is that the electric wrench 4 can be indirectly controlled by the wireless remote control 7.

[0031] Preferably, the hammer 510 abuts against the filter screen 51. The purpose of this arrangement is to enable the hammer 510 to clean the dust adhering to the filter screen.

[0032] Example 2

[0033] like Figure 1 and Figure 5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes an adjustment mechanism 6 including a housing 61 and a spring 62. The housing 61 is fixedly connected to the outer periphery of the sleeve rod 2 on one side. One end of the spring 62 is fixedly connected to the inner top wall of the sleeve rod 2, and the other end of the spring 62 is fixedly connected to the top of the long rod 1. An insert rod 63 is slidably connected inside the housing 61. A movable plate 64 is fixedly connected to one side of the insert rod 63, and a spring 65 is sleeved on the other side of the insert rod 63.

[0034] The purpose of this design is to allow for tightening or loosening of bolts or nuts in dangerous or hard-to-reach locations. By pulling down the long rod 1 and stretching the spring 62, the insertion rod 63, with its curved end, is compressed as the long rod 1 moves downward. This compression causes the moving plate 64 to move synchronously and compress the spring 65. When the rod reaches the appropriate length, the spring 65 pushes the moving plate 64 to reset the insertion rod 63 and insert it into the corresponding slot, completing the adjustment. After use, pulling the insertion rod 63 outward causes the baffle 53 to compress the spring 65. The elastic force of the spring 62 then resets the long rod 1. Once retracted, the insertion rod 63 is released, and the spring 65 re-inserts it into the corresponding slot, thus reducing the size of the device and making it easier to carry.

[0035] Preferably, one end of the second spring 65 is fixedly connected to the middle of the movable plate 64, and the other end of the second spring 65 is fixedly connected to the inner wall of the outer casing 61. The purpose of this arrangement is that the second spring 65 provides elastic force for the movable plate 64 to reset.

[0036] Preferably, the outer side of the movable plate 64 is slidably connected to the inside of the housing 61. The purpose of this arrangement is to enable the movable plate to slide stably.

[0037] Preferably, one end of the insertion rod 63 is arc-shaped, and the other end of the insertion rod 63 passes through the sleeve rod 2 and is slidably connected inside the long rod 1. The purpose of this arrangement is that the arc-shaped end of the insertion rod 63 allows the insertion rod 63 to be pushed into the outer shell 61 when the long rod 1 is pulled, and the slidable connection between the insertion rod 63 and the long rod 1 allows the insertion rod 63 to limit the long rod 1.

[0038] Preferably, a handle 66 is fixedly connected to the side end of the insertion rod 63. The purpose of this arrangement is to provide a gripping point for the staff.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
