Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mobile vehicle technology, specifically, it relates to a mechanical torque vehicle. Background Technology
[0002] Torque alters an object's angular momentum, i.e., its rotational properties, or causes it to twist. An object in equilibrium experiences not only zero force but also zero torque. The concept of torque has wide applications in mechanics and engineering.
[0003] Chinese patent CN221111599U discloses a mechanical torque wrench, including a handle, a connecting mechanism, and a wrench holder. The bottom of the wrench holder is mounted inside the handle via the connecting mechanism. A wrench head is provided on one side of the wrench holder. A turntable is rotatably connected to the bottom of the handle, and a gripping mechanism for applying force in different directions is rotatably connected to the turntable. Conventional torque wrenches prioritize opening and can only twist small items, without utilizing structures that allow for greater rotation.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mechanical torque vehicle, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A mechanical torque vehicle includes: a body, characterized in that a base is provided inside the body, a shell is provided on the top of the base near the front, a clamp is provided inside the shell, a T-slot is formed on the surface of the clamp, a T-block is provided inside the T-slot, a pawl is fixedly connected to the surface of the T-block, a connecting post is provided on the back of the clamp, a bearing is provided on the outside of the clamp against the shell, a connecting plate is provided on the back of the connecting post, a support frame is provided on the outside of the connecting plate, a rotating seat is provided on the back of the connecting plate, and a first throttle is mounted on the surface of the rotating seat.
[0008] Optionally, a second throttle is provided behind the first throttle on the surface of the rotating seat, and a third throttle is provided behind the second throttle, with the diameters of the first, second, and third throttle decreasing in that order.
[0009] Optionally, a clamping screw is provided inside the T-slot, a bevel gear is provided at the front end of the clamping screw, and a locking buckle is provided on the side of the clamp.
[0010] Optionally, a propulsion screw is longitudinally arranged inside the vehicle body, and a crank handle is provided at the end of the propulsion screw, with the propulsion screw passing through the center of the base.
[0011] Optionally, the bottom of the vehicle body is equipped with casters.
[0012] Optionally, fixed feet are provided on both sides of the vehicle body at the middle position of the universal wheels.
[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0014] 1. This mechanical torque car clamps the corresponding device with the front clamping jaws, and adjusts the clamp by rotating the three handles at the end. The diameter of the three handles increases sequentially. The farther the edge of the corresponding handle is from the center of the connecting column, the greater the torque and the less effort is required to rotate, but the longer the circumference traveled in one rotation and the longer the time. Multiple sets of handles are available for the operator to choose from to deal with different sized clamping devices.
[0015] 2. This mechanical torque cart is easy to adjust in position via the bottom universal wheels. The entire cart is fixed by the fixed feet on both sides. Turning the handle pushes the base to bring the clamp closer to the object to be clamped. The adjustment of the entire device is relatively simple and the transfer is more convenient.

Detailed Implementation
[0025] The present invention will now be described in further detail with reference to the accompanying drawings.
[0026] Please see Figure 1-4 As shown, this embodiment provides a mechanical torque vehicle, including: a vehicle body 1.
[0027] like Figure 1-4 As shown, in this embodiment, a base 2 is provided inside the vehicle body 1. A housing 3 is provided on the top of the base 2 near the front. A clamp 4 is provided inside the housing 3. A T-slot 5 is formed on the surface of the clamp 4. A T-block 6 is provided inside the T-slot 5. A claw 7 is fixedly connected to the surface of the T-block 6. A connecting post 11 is provided on the back of the clamp 4. A bearing 20 is provided on the outside of the clamp 4 in contact with the housing 3. A connecting plate 13 is provided on the back of the connecting post 11. A support frame 12 is provided on the outside of the connecting plate 13. A rotating seat 14 is provided on the back of the connecting plate 13. A first throttle 15 is mounted on the surface of the rotating seat 14. The entire torque vehicle holds the corresponding devices by clamping them with the clamp 4 at the front end. Then, rotating the first handle 15 located at the rear drives the clamp 4 to rotate, thereby rotating the device. The entire clamp 4 is installed vertically inside the housing 3 for protection. The jaw 7 at the front of the clamp 4 faces the front of the entire device horizontally and is clamped by the jaw 7. The housing 3 is placed on the base 2. The back of the clamp 4 is connected to the connecting plate 13 through the connecting column 11. By rotating the first handle 15, the rotating seat 14 on the connecting plate 13 is rotated, thereby driving the connecting column 11 to finally drive the clamp 4 to rotate. The outer ring of the clamp 4 is embedded in the housing 3 and is fitted with a bearing 20 for rotation. The rear connecting plate 13 is supported by the support frame 12.
[0028] like Figure 2As shown, in this embodiment, the surface of the rotating seat 14 is provided with a second rotating handle 16 behind the first rotating handle 15, and a third rotating handle 17 behind the second rotating handle 16. The diameters of the first rotating handle 15, the second rotating handle 16, and the third rotating handle 17 decrease accordingly. Among them, there are three rotating handles 17 on the rotating seat 14 at the end. The first rotating handle 15 is closer to the connecting plate 13 and has the largest diameter. The third rotating handle 17 at the very end has the smallest diameter. The second rotating handle 16, located in the middle, is directly between the two. The different diameters result in different distances from the edge of the grip to the center of the rotating seat 14 during rotation. The greater the distance, the greater the torque and the less effort is required to rotate. However, the circumference traveled in one rotation is longer, and the time is also longer. When the clamping device is heavy, the rotation time can be extended to reduce the applied force. Conversely, the rotation effect can be improved by reducing the rotation time.
[0029] like Figure 4 As shown, the T-slot 5 in this embodiment is provided with a clamping screw 8 inside, and a bevel gear 9 is provided at the front end of the clamping screw 8. A locking buckle 10 is provided on the side of the clamp 4. The locking buckle 10 is connected to one clamping screw 8. The locking buckle 10 is rotated by an external rotating pin to drive the clamping screw 8 to rotate. There are four clamping screws 8 inside the T-slot 5 that form a cross on the clamp 4. One end of each clamping screw 8 is provided with a bevel gear 9. The four bevel gears 9 are connected to each other and mesh, so that when a single clamping screw 8 is rotated by the locking buckle 10, it drives all the clamping screws 8 to rotate. This allows the threads on the clamping screw 8 to mesh with the threads in the threaded holes on the T-block 6, thereby allowing the T-block 6 to move in the T-slot 5. This allows the four claws 7 to simultaneously converge towards the center to clamp the item, or move in the opposite direction to release it.
[0030] like Figure 2 , 3 As shown, in this embodiment, a push screw 18 is longitudinally arranged inside the vehicle body 1, and a crank handle 19 is provided at the end of the push screw 18. The push screw 18 passes through the center of the base 2. A frame is provided on the top outer ring of the vehicle body 1. The base 2 is placed on the vehicle body 1 and fixed by the push screw 18. When the crank handle 19 is turned on the outside, the push screw 18 engages with the threaded hole on the base 2 through the thread, allowing the base 2 to move forward or backward on the vehicle body 1, thereby adjusting the position of the front clamp 4 so that it is closer to the clamped item and adjusting the overall center of gravity.
[0031] like Figure 2 As shown, the bottom of the vehicle body 1 in this embodiment is provided with universal wheels 21; wherein, the four universal wheels 21 at the bottom enable the vehicle body 1 to move more conveniently and improve the overall flexibility.
[0032] like Figure 2As shown, in this embodiment, fixed feet 22 are provided on both sides of the vehicle body 1 at the middle position of the universal wheels 21; wherein, the fixed feet 22 fix the bottom support to the ground by rotating the rotating rod, thereby fixing the entire vehicle body 1, and the stability is improved by fixing it by the fixed feet 22 when rotating.
[0033] Working principle: Adjust the position of the vehicle body 1 and fix the vehicle body 1 with the fixing foot 22. Turn the crank handle 19 to move the base 2 so that the clamp 4 can quickly approach the object. Turn the locking buckle 10 to bring the claw 7 close to clamp the object. Select the appropriate crank handle to rotate the clamped object according to the force or mass of the object.
