Description

Technical Field

[0001] This utility model relates to the field of furniture handling technology, and in particular to a furniture handling vehicle with adjustable spacing. Background Technology

[0002] Furniture moving carts are mobile tools specifically designed for moving furniture. They are typically equipped with flatbeds and wheels, and have both moving and transport functions. Their design emphasizes load-bearing capacity and flexibility, making them suitable for household moves, shopping mall displays, and logistics transportation scenarios, significantly reducing the intensity of manual handling and improving efficiency.

[0003] In the furniture handling industry, existing pallet trucks, such as manual hydraulic forklifts, generally suffer from fixed fork arm or clamping arm spacing. These traditional devices typically employ a fixed, equidistant fork arm spacing design, making dynamic adjustment impossible based on actual handling needs. When dealing with furniture longer than the fork arm spacing, operators must employ non-standard operating methods such as multiple position adjustments or tilting, significantly reducing handling efficiency and potentially causing furniture slippage or equipment tipping due to a shift in the center of gravity, posing safety hazards. Furthermore, the fixed spacing design limits the pallet truck's adaptability to irregularly shaped furniture or non-standard sized items, failing to meet the diverse and personalized handling needs of modern homes. These shortcomings are particularly pronounced when handling large panels, long, narrow furniture, or modular furniture, becoming key technical bottlenecks restricting handling efficiency and safety.

[0004] Therefore, there is an urgent need to provide a furniture moving vehicle with adjustable spacing to solve the above problems. 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 furniture moving cart with adjustable spacing.

[0006] To solve the above-mentioned technical problems, the present invention provides a furniture moving vehicle with adjustable spacing, including a manual forklift and two forklift arms installed at the front end of the manual forklift, wherein a drive mechanism is installed inside the manual forklift.

[0007] The output end of the drive mechanism is connected to a gear, and the drive mechanism is used to drive the gear to rotate. The bottom of the manual forklift is connected to a counter mechanism that meshes with the gear.

[0008] The two ends of the opposing mechanism are respectively connected to the two forklift arms. The opposing mechanism is used to drive the two forklift arms to move. A limiting mechanism for limiting the movement is connected between the two forklift arms.

[0009] The two forklift arms are externally connected to a rotating mechanism, and the top of the rotating mechanism is connected to two baffles. The rotating mechanism is used to drive the baffles to deflect. The rear end of the manual forklift is connected to a braking mechanism for braking.

[0010] The present invention is further configured such that: the drive mechanism includes a first bracket fixedly connected inside the manual forklift, a motor is installed inside the first bracket, and the output end of the motor passes through the manual forklift and is fixedly connected to a gear.

[0011] Through the above technical solution, the function of the drive mechanism is to drive the gear to rotate; the motor is fixed inside the manual forklift through the first bracket, and its output end directly drives the gear to rotate, converting electrical energy into mechanical energy, and providing a power source for adjusting the forklift arm spacing; the use of motor drive to replace manual adjustment realizes the automation and precision of spacing adjustment, reduces the intensity of operation, and improves adjustment efficiency and response speed.

[0012] The present invention is further configured such that: the opposing mechanism includes two racks slidably connected to the bottom of the manual forklift, the two racks respectively meshing with gears and being centrally symmetrical, the ends of the two racks away from the gears respectively being fixedly connected to the two forklift arms, and both racks passing through the two forklift arms.

[0013] Through the above technical solution, the function of the opposing mechanism is to make the two forklift arms move towards each other; when the gear rotates, the two centrally symmetrical racks slide in opposite directions, respectively driving the two forklift arms to move towards or in opposite directions, thereby realizing the spacing adjustment; the rotational motion is converted into linear motion through the gear and rack transmission, ensuring that the two forklift arms move synchronously in opposite directions, the adjustment process is smooth and without deviation, and solves the problem of center of gravity shift caused by asynchronous adjustment in traditional manual adjustment.

[0014] The present invention is further configured such that: the limiting mechanism includes two sets of sleeves, each set having two sleeves, and the two sets of sleeves facing opposite directions; the two sets of sleeves are respectively fixedly connected to the two forklift arms; each set of sleeves is slidably connected to a sliding shaft, and similarly, each set of sliding shafts has two sliding shafts, and the two sets of sliding shafts are respectively fixedly connected to the two forklift arms.

[0015] Through the above technical solution, the function of the limiting mechanism is to limit and guide the forklift arm; the sleeve and the sliding shaft are slidably engaged, and when the forklift arm moves, the sliding shaft slides along the axial direction of the sleeve, constraining the forklift arm to only move in a straight line in a preset direction; the rigid sliding guide restricts the movement trajectory of the forklift arm, preventing deflection or jamming during the adjustment process, and ensuring the spacing adjustment accuracy and equipment stability.

[0016] The present invention is further configured such that: the rotating mechanism includes two second brackets fixedly connected to the outward side of the two forklift arms respectively, and corresponding one to one; each of the two second brackets is fixedly connected to a limiting shaft; each of the two limiting shafts is slidably connected to a sliding block; each of the two sliding blocks is rotatably connected to a rotating shaft at its top; each of the two rotating shafts is fixedly connected to one end of two baffles respectively; each of the two baffles is rotatably connected to another sliding block via a rotating shaft at its other end; and each of the two sliding blocks is slidably connected to the inner side of the two forklift arms respectively.

[0017] Through the above technical solution, the function of the rotating mechanism is to deflect the baffle until it is perpendicular to the ground, thereby holding the furniture in place; the sliding block slides along the limiting shaft to adjust the horizontal position of the baffle, and the rotating shaft drives the baffle to deflect and adjust the tilt angle to adapt to the protection needs of furniture of different sizes; through the dual adjustment of sliding and rotation, the position and angle of the baffle can be flexibly adjusted, enhancing the wrapping and anti-slip ability of the furniture and improving the safety of handling.

[0018] The present invention is further configured such that: a first torsion spring is sleeved on the outside of each of the two rotating shafts, and the two ends of the first torsion spring are fixedly connected to the outside of the rotating shaft and the sliding block, respectively. A vertical plate is fixedly connected to one side of each of the two sliding blocks, and a bolt is rotatably connected to the outside of each of the two sliding blocks by means of a thread. One end of the bolt contacts and abuts against the limiting shaft.

[0019] Through the above technical solution, the first torsion spring provides the baffle reset force through elastic deformation, and the bolt fixes the position of the sliding block through friction with the limiting shaft; the first torsion spring realizes the automatic return of the baffle, simplifying the operation process; the bolt provides the sliding block position locking function to prevent the baffle from shifting during transportation and enhance the structural stability.

[0020] The present invention is further configured such that: the braking mechanism includes a long shaft rotatably connected to the rear end of the manual forklift, a roller standing on the ground is installed at the bottom of the long shaft, a short shaft located above the roller is fixedly connected to the outside of the long shaft, an arc-shaped foot pedal is rotatably connected to the outside of the short shaft, a second torsion spring is sleeved on the outside of the short shaft, the outside of the second torsion spring is fixedly connected to the outside of the short shaft and the foot pedal respectively, and swivel wheels are installed at the bottom of both forklift arms.

[0021] Through the above technical solution, the function of the braking mechanism is to brake the roller; when the pedal is pressed, the pedal contacts the roller and thus brakes; after being released, the second torsion spring drives the pedal to return to its original position, and the brake is released after the pedal is disengaged from the roller; the braking and release are achieved by pressing, which solves the problem of slow braking response of traditional pallet trucks and improves safety and ease of operation in emergency situations.

[0022] The beneficial effects of this utility model are as follows:

[0036] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0037] Please see Figure 1 - Figure 10 This embodiment of a furniture handling vehicle with adjustable spacing includes a manual forklift 1 and two forklift arms 2 installed at the front end of the manual forklift 1. A drive mechanism 3 is installed inside the manual forklift 1, and a gear 4 is connected to the output end of the drive mechanism 3. The drive mechanism 3 is used to drive the gear 4 to rotate. The drive mechanism 3 includes a first bracket 301 fixedly connected inside the manual forklift 1. A motor 302 is installed inside the first bracket 301. The output end of the motor 302 passes through the manual forklift 1 and is fixedly connected to the gear 4. The function of the drive mechanism 3 is to drive the gear 4 to rotate. The motor 302 is fixed inside the manual forklift 1 through the first bracket 301, and its output end directly drives the gear 4 to rotate, converting electrical energy into mechanical energy to provide a power source for adjusting the spacing of the forklift arms 2. The use of the motor 302 to drive the adjustment replaces manual adjustment, realizing the automation and precision of the spacing adjustment, reducing the intensity of operation, and improving the adjustment efficiency and response speed.

[0038] like Figure 5 - Figure 8As shown, the bottom of the manual forklift 1 is connected to a counter-moving mechanism 5 that meshes with gear 4. Both ends of the counter-moving mechanism 5 are respectively connected to two forklift arms 2. The counter-moving mechanism 5 is used to drive the two forklift arms 2 to move. The counter-moving mechanism 5 includes two racks 501 slidably connected to the bottom of the manual forklift 1. The two racks 501 mesh with gear 4 and are centrally symmetrical. The ends of the two racks 501 away from gear 4 are respectively fixedly connected to the two forklift arms 2, and both racks 501 pass through the two forklift arms 2. The function of the counter-moving mechanism 5 is to make the two forklift arms 2 move towards each other. When gear 4 rotates, the two centrally symmetrical racks 501 slide in opposite directions, respectively driving the two forklift arms 2 to move towards or in the opposite direction, thus achieving spacing adjustment. The rotational motion is converted into linear motion through the transmission of gear 4 and racks 501, ensuring that the two forklift arms 2 move synchronously in opposite directions. The adjustment process is smooth and without deviation, solving the problem of center of gravity shift caused by asynchronous traditional manual adjustment.

[0039] like Figure 5 - Figure 8 As shown, a limiting mechanism 6 for limiting movement is connected between the two forklift arms 2. The limiting mechanism 6 includes two sets of sleeves 601, each set containing two sleeves, and the two sets of sleeves 601 face opposite directions. The two sets of sleeves 601 are fixedly connected to the two forklift arms 2 one-to-one. Each set of sleeves 601 is slidably connected to a sliding shaft 602, and similarly, each set of sliding shafts 602 contains two sliding shafts, which are fixedly connected to the two forklift arms 2 one-to-one. The function of the limiting mechanism 6 is to limit and guide the forklift arms 2. The sleeves 601 and the sliding shafts 602 are slidably engaged. When the forklift arms 2 move, the sliding shafts 602 slide along the axial direction of the sleeves 601, constraining the forklift arms 2 to move only in a straight line in a preset direction. By rigidly sliding and guiding the movement of the forklift arms 2, the movement trajectory of the forklift arms 2 is restricted, preventing deflection or jamming during the adjustment process, and ensuring the accuracy of the spacing adjustment and the stability of the equipment.

[0040] like Figure 9 - Figure 10As shown, a rotating mechanism 7 is externally connected to the two forklift arms 2. Two baffles 8 are connected to the top of the rotating mechanism 7. The rotating mechanism 7 is used to drive the baffles 8 to deflect. The rotating mechanism 7 includes two second brackets 701 fixedly connected to the outward-facing side of the two forklift arms 2, in a one-to-one correspondence. A limit shaft 702 is fixedly connected inside each of the two second brackets 701. A sliding block 703 is slidably connected to the outside of each of the two limit shafts 702. A rotating shaft 704 is rotatably connected to the top of each of the two sliding blocks 703. The two rotating shafts 704 are fixedly connected to one end of each of the two baffles 8, respectively. The other end of each baffle 8 is rotatably connected to another sliding block 703 via a rotating shaft. The two sliding blocks 703 are respectively slidably connected to the inner side of the two forklift arms 2. The function of the rotating mechanism 7 is to deflect the baffle 8 until it is perpendicular to the ground, thereby holding the furniture in place. The sliding block 703 slides along the limiting shaft 702 to adjust the horizontal position of the baffle 8. The rotating shaft 704 drives the baffle 8 to deflect and adjust the tilt angle to adapt to the protection needs of furniture of different sizes. The position and angle of the baffle 8 can be flexibly adjusted through the dual adjustment of sliding and rotation, which enhances the wrapping and anti-slip ability of the furniture and improves the safety of handling.

[0041] like Figure 9 - Figure 10 As shown, a first torsion spring 705 is fitted around the outside of each of the two rotating shafts 704. The two ends of the first torsion spring 705 are fixedly connected to the outside of the rotating shaft 704 and the sliding block 703, respectively. A vertical plate 706 is fixedly connected to one side of each of the two sliding blocks 703, and a bolt 707 is rotatably connected to the outside of each of the two sliding blocks 703 by a thread. One end of the bolt 707 contacts and abuts against the limiting shaft 702. The first torsion spring 705 provides the baffle 8 with a restoring force through elastic deformation, and the bolt 707 fixes the position of the sliding block 703 through friction with the limiting shaft 702. The first torsion spring 705 realizes the automatic return of the baffle 8, simplifying the operation process. The bolt 707 provides the position locking function of the sliding block 703 to prevent the baffle 8 from shifting during transportation and enhance the structural stability.

[0042] like Figure 1 - Figure 4As shown, a braking mechanism 9 for braking is connected to the rear end of the manual forklift 1. The braking mechanism 9 includes a long shaft 901 rotatably connected to the rear end of the manual forklift 1. A roller 902 standing on the ground is mounted on the bottom of the long shaft 901. A short shaft 903 located above the roller 902 is fixedly connected to the outside of the long shaft 901. An arc-shaped foot pedal 904 is rotatably connected to the outside of the short shaft 903. A second torsion spring 905 is sleeved on the outside of the short shaft 903. The outside of the second torsion spring 905 is connected to the outside of the short shaft 903 and the foot pedal, respectively. The two forklift arms 2 are fixedly connected by a 904. Both arms are equipped with casters 906 at their bottom. The braking mechanism 9 brakes the rollers 902. When the foot pedal 904 is pressed, it contacts the rollers 902, thus braking. When released, the second torsion spring 905 drives the foot pedal 904 to return to its original position, and the brake is released after the foot pedal 904 disengages from the rollers 902. The foot pedal enables rapid braking and release, solving the problem of slow braking response in traditional pallet trucks and improving safety and ease of operation in emergency situations.

[0043] In use, this invention drives the gear 4 to rotate via the motor 302, causing two centrally symmetrical racks 501 to slide in opposite directions, enabling the two forklift arms 2 to move synchronously towards or away from each other, achieving dynamic spacing adjustment to accommodate furniture of different sizes. The rigid sliding fit between the sliding shaft 602 and the sleeve 601 ensures the linear movement trajectory of the forklift arms 2, preventing deflection and jamming. The sliding block 703 adjusts its position along the limiting shaft 702 and, in conjunction with the rotating shaft 704, drives the baffle 8 to deflect, making the baffle 8 vertically abut against the side of the furniture. The first torsion spring 705 provides automatic reset force, and the bolt 707 locks the position of the sliding block 703 to prevent displacement. When the step plate 904 is pressed, the arc plate contacts the roller 902 for braking. After release, it automatically resets and releases the brake under the action of the second torsion spring 905. This design replaces manual operation with automatic adjustment via the motor 302, solving the problems of low handling efficiency and slippage risk caused by traditional fixed spacing. It achieves precise matching of the forklift arm spacing, stable wrapping of furniture, and rapid braking, significantly improving handling safety and adaptability.
