Description

Technical Field

[0001] The present invention belongs to the technical field of manual tools, and particularly relates to a new type of lithium battery direct drive torque wrench. Background Art

[0002] A torque wrench generally refers to a moment wrench, and the moment wrench can be divided into an electric moment wrench, a pneumatic moment wrench, a hydraulic moment wrench, and a manual pressure wrench according to the power source. The electric torque wrench can provide a relatively high torque and is widely used. When the tightness of screws and bolts is crucial, a torque wrench can allow an operator to apply a specific torque value.

[0003] Chinese Patent CN102825570B discloses a vertical double-electric torque wrench for disassembling and assembling railway rail connection bolts. This vertical double-electric torque wrench includes a housing, a power output assembly, and a socket. The power output assembly is installed in the housing. The power output assembly includes at least one battery and an electric motor. The battery is connected to the electric motor. The output shaft at the lower end of the electric motor is in transmission connection with the socket. A vertical rod is fixedly installed at the upper end of the housing. The axis of the vertical rod coincides with the axis of the output shaft of the electric motor. A vertical operating handle is installed at the upper end of the vertical rod. By setting the vertical rod, when disassembling and assembling bolts installed on the sleeper, the operator does not need to squat down and bend over to operate, which can reduce the labor intensity of the operator and thus solve the problem that the operator is prone to fatigue. However, in actual use, the driving part inside the torque wrench is prone to generate a large amount of heat during operation, and the dissipation of heat requires the cooling fan of the driving part to exhaust. Therefore, when the torque wrench body is in a narrow area, the narrow air duct is likely to cause insufficient air intake, resulting in a decrease in the heat dissipation efficiency and not being able to well meet the heat dissipation needs, and there is a certain room for improvement.

[0015] As a further description of the above - mentioned technical solution:

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, when the driving part in the driving chamber generates heat during operation, the heat-conducting shell can introduce the heat into the external assembly components and the heat exchange components through contact, and when the blades in the driving part rotate during operation, the blades can enter the outside of the heat-conducting shell through the air duct after taking in air and discharging heat. The air entering the heat dissipation chamber can further exchange the heat stored in the body and discharge it after contacting the assembly components and the heat exchange components for heat exchange. After contacting the air guide components in the inner cavity of the heat dissipation chamber to generate eddy current circulation, further refluxes and absorbs heat, and then discharges it through the rear side of the body. The arrangement of the annular heat dissipation chamber can realize multi-directional air intake in the air duct. When operating in a narrow area, the relative position of the top air inlet pipe can be adjusted by rotating the heat dissipation chamber to meet the optional adjustment of a large number of air inlet angles of the air inlet pipe, which is beneficial to adjust the purge position in a narrow area and improve the processing adaptability.

[0027] 2. In the present invention, through the designed air guiding assembly, when the driving part in the body driving chamber works to drive the blades to rotate and suck air, the air can enter through the through slots outside the heat dissipation chamber, and the entering air can contact one side of the air guiding part with an arc shape at the bottom under the spiral guiding action of multiple air guiding rods. The arc-shaped surface on one side of the air guiding part can cause the entering air to generate a rotating spiral and then be introduced into the heat exchange assembly and the assembly component through the heat dissipation chamber. Through the setting of multiple large-aperture through slots in the heat dissipation chamber, the air intake is increased. The cooperation of the guiding pipe and the air guiding part can reduce the entry of external water vapor and impurities. While increasing the entry of large-flux air, the dust entering the driving chamber and the body is reduced, effectively improving the dust prevention effect.

[0028] 3. In the present invention, through the designed assembly component and heat exchange component, when external air enters, the air entering through the air guiding assembly can enter the assembly slot through the ventilation slot. After contacting the heat exchange liquid plate through the ventilation slot, the air can perform heat exchange treatment with the lateral fins or heat exchange fins on one side of the heat exchange liquid plate according to the air inlet direction. The heat exchange liquid filled in the heat exchange liquid plate fully absorbs and disperses the heat between multiple lateral fins and heat exchange fins. When the air flows and contacts for heat exchange, the heat of the heat conduction shell and the internal driving parts is reduced. When the air that has not entered the assembly slot encounters the closed cover, it enters through the ventilation slot on one side of the rear assembly slot, improving the air combination and flow effect and the overall heat exchange treatment efficiency.

[0029] 4. In the present invention, through the designed heat exchange component, when the body moves, the heat exchange liquid plate can be shortened through the top telescopic rod. When the heat exchange liquid plate vibrates, it can absorb energy and reduce vibration by squeezing the spring through the telescopic rod, improving the stability of the heat exchange liquid plate device. And when a large amount of air enters, the heat exchange liquid plate can slide outside the limit slider through the chute, causing the heat exchange liquid plate to shake, reducing the adhesion of dust on the surface of the heat exchange liquid plate, and improving the heat dissipation treatment efficiency. Through the setting of the heat conduction shell, the contact with the internal air is reduced, improving the cleanliness and stability of the internal environment. Through the external placement of the air duct, the subsequent processability is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0042] Please refer to Figures 1-9, the present invention provides a technical solution: a new type of lithium - battery direct - drive torque wrench, which includes a body 1. A drive chamber 2 is provided at the rear side of the body 1, and a grip rod 11 is fixedly installed at the bottom of the drive chamber 2. The bottom end of the grip rod 11 is detachably connected to a battery holder 12. A heat - conducting shell 8 is fixedly installed in the inner cavity of the body 1, and a torque - adjusting mechanism and a driving part are fixedly installed in the heat - conducting shell 8. A plurality of assembly components 7 are fixedly installed around the axis of the outer part of the heat - conducting shell 8. A heat - exchange component 6 for heat exchange is arranged in the inner cavity of the assembly component 7. A heat - dissipation chamber 3 is rotatably connected to the outer side of one side of the body 1. A plurality of air - guiding components 4 with adjustable angles are arranged on the outer side wall of the heat - dissipation chamber 3 for dissipating heat from the inside of the body 1 after ventilation. A blowing air pipe is communicated with one side of the heat - dissipation chamber 3. A plurality of through - slots are formed around the axis of the outer side wall of the heat - dissipation chamber 3, and a travel slot 14 is formed in the inner cavity of the heat - dissipation chamber 3. The travel slot 14 is communicated with the through - slots, and the air - guiding component 4 is arranged in the through - slots. An air inlet pipe 5 is communicated with the top of the heat - dissipation chamber 3, and a sealing ring is nested between the inner cavity of the heat - dissipation chamber 3 and the outside of the body 1.

[0043] The specific implementation method is as follows: When the driving part in the drive chamber 2 works to generate heat, the heat - conducting shell 8 can conduct the heat into the external assembly component 7 and the heat - exchange component 6 through contact. And when the blades rotate after the driving part works, the air after the blades work for air intake and heat dissipation can enter the outside of the heat - conducting shell 8 through the air duct. And the air entering the heat - dissipation chamber 3 can further exchange the heat generated inside the body 1 after contacting and exchanging heat with the assembly component 7 and the heat - exchange component 6 and then be discharged. And after contacting the air - guiding component 4 in the inner cavity of the heat - dissipation chamber 3 to generate a vortex circulation and further absorb heat by reflux, it is discharged from the rear side of the body 1. Through the setting of the annular heat - dissipation chamber 3, multi - directional air intake of the air duct can be realized. And when operating in a narrow area, the relative position of the top air inlet pipe 5 can be adjusted by rotating the heat - dissipation chamber 3, meeting the optional adjustment of the large - angle air intake of the air inlet pipe 5, which is beneficial to adjusting the purging position in a narrow area and improving the adaptability.

[0044] Please refer to Figures 5-7 , the air - guiding component 4 includes a guiding pipe 402 and an air - guiding part 403. A rotating rod 404 is fixedly connected to the end of the air - guiding part 403. An articulated rod 15 is hinged in the inner cavity of the rotating rod 404. The articulated rod 15 is fixedly connected between both sides of the inner cavity of the through - slot. A wind - guiding seat 401 is fixedly connected to the top of the guiding pipe 402. The wind - guiding seat 401 is embedded in the inner cavity of the through - slot. An opening is formed at the top of the wind - guiding seat 401, and the top of the guiding pipe 402 is communicated with one side of the opening. The end of the guiding pipe 402 is in contact with the inner side of the air - guiding part 403. A fixed rod 406 is fixedly connected between both sides of the inner cavity of the opening of the wind - guiding seat 401. A wind - guiding rod 407 is fixedly connected to the bottom of the fixed rod 406. The outer side wall of the wind - guiding rod 407 is spiral. The bottom end of the wind - guiding rod 407 extends to the bottom of the guiding pipe 402. The cross - sectional shape of the end of the air - guiding part 403 is semi - circular arc for guiding the air to flow out in the reverse direction after the wind - guiding seat 401 guides the air. A plurality of guiding blocks 405 are fixedly connected to one side of the air - guiding part 403, and the cross - sectional shape of the guiding block 405 is conical.

[0045] The implementation manner is specifically as follows: Through the designed air guiding component 4, when the driving part in the driving bin 2 of the fuselage 1 works to drive the blades to rotate and suck air, the air can enter through the through slots outside the heat dissipation bin 3, and the entering air can contact one side of the air guiding part 403 with an arc shape at the bottom under the spiral guiding action of multiple air guiding rods 407. The arc-shaped surface on one side of the air guiding part 403 can make the entering air generate a rotating spiral and then be introduced into the heat exchange component 6 and the assembly component 7 through the heat dissipation bin 3. Thus, the air intake can be increased by setting multiple large-aperture through slots in the heat dissipation bin 3. At the same time, the cooperation of the guiding pipe 402 and the air guiding part 403 can reduce the entry of external water vapor and impurities. While increasing the entry of large-flux air, the dust entering the driving bin 2 and the fuselage 1 can be reduced, effectively improving the dust prevention effect. Through the designed guiding block 405, the conical guiding block 405 can further absorb the entering dust and impurities, improving the air intake quality;

[0046] Through the designed spiral air guiding rods 407, the air entering through the bolts can swing the particles in the incoming air to the side wall of the guiding pipe 402 and deposit them on the inner arc of the air guiding part 403, ensuring the air intake treatment effect.

[0047] Please refer to Figures 4-5 , the assembly component 7 includes an assembly groove 701, the assembly groove 701 is fixedly connected to one side of the outer wall of the heat conducting shell 8, a plurality of ventilation grooves 702 arranged in an array are formed on the outer side wall of the assembly groove 701, and the cross-sectional shape of the ventilation grooves 702 is inclined. A sealing cover 10 is embedded between a plurality of assembly grooves 701, and the sealing cover 10 is located inside the fuselage 1. The heat exchange component 6 includes a heat exchange liquid plate 601, the heat exchange liquid plate 601 is slidably connected to the inner cavity of the assembly groove 701, a plurality of vertically arranged heat exchange fins 602 are fixedly installed at both ends on both sides of the heat exchange liquid plate 601, and a transverse fin 603 is fixedly connected between two adjacent heat exchange fins 602.

[0048] The implementation manner is specifically as follows: Through the designed assembly component 7 and heat exchange component 6, when external air enters, the air entering through the air guiding component 4 can enter the assembly groove 701 through the ventilation grooves 702. After contacting the heat exchange liquid plate 601 through the ventilation grooves 702, the air can perform heat exchange treatment with the transverse fins 603 or the heat exchange fins 602 on one side of the heat exchange liquid plate 601 according to the incoming air direction. The heat exchange liquid filled in the heat exchange liquid plate 601 can fully absorb and disperse the heat between a plurality of transverse fins 603 and heat exchange fins 602. When the air flows and contacts for heat exchange, the heat of the heat conducting shell 8 and the internal driving parts is reduced. Through the designed sealing cover 10, the air that has not entered the assembly groove 701 can enter through the ventilation grooves 702 on one side of the rear assembly groove 701 after encountering the sealing cover 10, so as to improve the air combination and flow effect and the overall heat exchange treatment efficiency.

[0049] Please refer to Figures 8-9 , the heat exchange component 6 further includes a telescopic rod 604. The bottom end of the telescopic rod 604 is fixedly connected with a limit slider 606. The limit slider 606 is slidably connected in a chute 607 opened at the top of the heat exchange liquid plate 601. A spring 605 is sleeved on the outer side wall of the telescopic rod 604. One end of the spring 605 is connected to the top of the limit slider 606, and the other end of the spring 605 is connected to one side outside the telescopic rod 604. A limit member 9 is connected to the front side shaft body of the fuselage 1, and the cross-sectional shape of the limit member 9 is L-shaped. An adjustment button 13 is fixedly installed at the rear side of the drive bin 2, and the adjustment button 13 is in transmission connection with one side of the drive part for adjusting the torque.

[0050] The specific implementation method is as follows: Through the designed heat exchange component 6, when the fuselage 1 moves, the heat exchange liquid plate 601 can be shortened through the telescopic rod 604 at the top. When the heat exchange liquid plate 601 vibrates, it can absorb energy and reduce vibration by squeezing the spring 605 through the telescopic rod 604, thereby improving the stability of the heat exchange liquid plate 601 device. And when a large amount of air enters, the heat exchange liquid plate 601 can slide outside the limit slider 606 through the chute 607, causing the heat exchange liquid plate 601 to shake, reducing the adhesion of dust on the surface of the heat exchange liquid plate 601, and improving the heat dissipation efficiency. Through the setting of the heat conduction shell 8, the contact with the internal air is reduced, and the cleanliness and stability of the internal environment are improved. Through the external placement of the air duct, the subsequent processing capacity is improved.

[0051] Working principle: When in use, when the drive part in the drive bin 2 generates heat, the heat conduction shell 8 conducts the heat into the external assembly component 7 and the heat exchange component 6 through contact. When the blades rotate in the drive part, after the blades work to intake and exhaust heat, the air enters the outside of the heat conduction shell 8 through the air duct. The air entering the heat dissipation bin 3 exchanges heat with the assembly component 7 and the heat exchange component 6 and then further exchanges the stored heat in the fuselage 1 and discharges it. After contacting the air guide component 4 in the inner cavity of the heat dissipation bin 3, it generates a vortex circulation and further returns to absorb heat, and then is discharged from the rear side of the fuselage 1. Through the setting of the annular heat dissipation bin 3, multi-directional air intake of the air duct is realized. When operating in a narrow area, the relative position of the top air intake pipe 5 can be adjusted by rotating the heat dissipation bin 3 to adjust the air intake angle and adjust the purging position in the narrow area;

[0052] When the driving part in the driving bin 2 of the fuselage 1 drives the blades to rotate and suck air, the air enters through the through slots outside the heat dissipation bin 3. The entering air contacts one side of the air guiding part 403 with an arc-shaped bottom side under the spiral guiding action of multiple air guiding rods 407. The spiral air guiding rods 407 throw the particles in the incoming air to the side wall of the guiding pipe 402 and deposit them on the inner arc of the air guiding part 403 through the air entering through the bolt. The arc-shaped surface on one side of the air guiding part 403 causes the incoming air to generate a rotating spiral and then be introduced into the heat exchange component 6 and the assembly component 7 through the heat dissipation bin 3. Through the cooperation of the guiding pipe 402 and the air guiding part 403, the entry of external water vapor and impurities is reduced. While increasing the entry of high-throughput air, the dust entering the driving bin 2 and the fuselage 1 is reduced, improving the dust prevention effect. The conical guiding block 405 further absorbs the incoming dust and impurities;

[0053] When external air enters, the air entering through the air guiding component 4 enters the assembly slot 701 through the ventilation slot 702. After contacting the heat exchange liquid plate 601 through the ventilation slot 702, the air exchanges heat with the lateral fins 603 or the heat exchange fins 602 on one side of the heat exchange liquid plate 601 according to the incoming air direction. The heat exchange liquid filled in the heat exchange liquid plate 601 fully absorbs and disperses the heat between the multiple lateral fins 603 and the heat exchange fins 602. When the air flows and contacts for heat exchange, the heat of the heat conduction shell 8 and the internal driving parts is reduced. Through the designed closed cover 10, the air that has not entered the assembly slot 701 enters through the ventilation slot 702 on one side of the rear assembly slot 701 after encountering the closed cover 10, improving the air combination and flow effect and the overall heat exchange processing efficiency;

[0054] When the fuselage 1 moves, the heat exchange liquid plate 601 shortens through the top telescopic rod 604. When the heat exchange liquid plate 601 vibrates, the telescopic rod 604 squeezes the spring 605 to absorb energy and reduce vibration, improving the stability of the heat exchange liquid plate 601 device. When a large amount of air enters, the heat exchange liquid plate 601 slides outside the limit slider 606 through the sliding slot 607, causing the heat exchange liquid plate 601 to shake and reducing the adhesion of dust on the surface of the heat exchange liquid plate 601.

[0055] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
