Description

Technical Field

[0001] The present application relates to the technical field of forklift hand brake assembly, and in particular to a forklift hand brake assembly auxiliary mechanism. Background Art

[0002] A forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles that load, unload, stack and transport palletized goods over short distances. The hand brake of a forklift is a common and important part of a forklift. The hand brake can be operated by the operator to control the braking force of the entire vehicle, thereby achieving the parking brake of the entire vehicle. The existing hand brake zipper is generally connected to the forklift drive axle at one end and connected to the steel wire in the hand brake zipper at the other end. When assembling, the steel wire in the hand brake zipper must be pulled out from the outer leather tube of the zipper first, and then one end of it must be placed inside the hand brake bayonet. However, assembly tools are required during assembly.

[0003] In the utility model of the Chinese patent authorization announcement number CN219806033U, a forklift hand brake zipper assembly auxiliary device disclosed in the specification includes two handle bars, the two handle bars are rotatably connected to each other, and two clamping components, the two clamping components are respectively arranged on the two handle bars, the clamping components are used to clamp the hand brake zipper end, and the distance between the two clamping components changes according to the rotation of the two handle bars; the forklift hand brake zipper assembly auxiliary device solves the problem that the existing hand brake zipper and hand brake are mainly assembled by manual operation without specific assembly tools. On-site assemblers need to assemble the hand brake zipper end and the locking nut on the hand brake. Due to the characteristics of the assembly structure, the steel wire inside the hand brake zipper needs to be pulled out from the outer skin tube of the zipper first, because it is all wrapped inside the outer skin tube of the zipper in a normal state. In this process, the zipper end needs a certain amount of force to be pulled out, so it consumes physical strength and is difficult to operate;

[0004] In this comparative document, two handle bars are rotatably connected to each other, and the two handle bars are respectively provided with detachable clamping components for clamping the end of the handbrake zipper. After clamping, the steel wire inside the handbrake zipper is pulled out from the zipper, and the inner steel wire is put into the handbrake clamping mouth. The above process requires two operators to complete, and one of the operators needs to use both hands at the same time to complete the rotational connection of the two handle bars, which will reduce the efficiency of handbrake assembly. Utility Model Content

[0005] In order to solve the problem proposed above, that is, by rotatably connecting two handle rods to each other, clamping components for clamping the end of the handbrake cable are detachably arranged on the two handle rods respectively. After clamping, the inner steel wire in the handbrake cable is drawn out from the cable, and the inner steel wire is placed inside the handbrake bayonet. The above process requires two operators to complete, and one of the operators needs to use both hands at the same time to complete the rotational connection of the two handle rods, which will reduce the efficiency of handbrake assembly. The present application provides an auxiliary mechanism for forklift handbrake assembly.

[0008] A U-shaped block is fixedly connected to one side of the frame body. A lower tooth block is fixedly connected to the inner bottom wall of the U-shaped block. One end of the top of the lower tooth block is fixedly connected with a limiting column. An upper tooth block is movably sleeved on the outer surface of the limiting column. A second spring is movably sleeved on the middle outer surface of the limiting column. The two ends of the second spring respectively abut against the bottom end of the upper tooth block and the top end of the lower tooth block. Connecting blocks are fixedly connected to both sides of the upper tooth block. Connecting rods are fixedly connected to both sides of the movable rod. The two connecting blocks are respectively connected to the two connecting rods through two connecting lines. Guide wheels for guiding the two connecting lines are arranged at one corner of each of the two sides of the U-shaped block.

[0009] Preferably, the two connecting lines are each composed of a fiber rope and two limiting blocks. Through holes are opened at the bottom ends of the two connecting blocks and one ends of the two connecting rods. The two ends of the two fiber ropes respectively fixedly penetrate through the through holes opened at the bottom ends of the two connecting blocks and one ends of the two connecting rods. The four limiting blocks are respectively fixedly sleeved on the two ends of the two fiber ropes.

[0010] Preferably, the two guide wheels are each composed of a support shaft, a sealed bearing and two retaining rings. The two support shafts are respectively fixedly connected to one corner of each of the two sides of the U-shaped block. The inner bearing rings of the two sealed bearings are respectively fixedly sleeved on the outer surfaces of the two support shafts. The four retaining rings are respectively fixedly sleeved on the edges of the outer bearing rings of the two sealed bearings. One side of each of the two fiber ropes abuts against the outer surfaces of the outer bearing rings of the two sealed bearings.

[0011] Preferably, a first spring is movably placed inside a cavity formed in the middle of an inner sidewall of the frame body. One end of the first spring abuts against the inner sidewall of the inner cavity, and the other end of the first spring abuts against one side of the movable block.

[0017] The following further describes the present application in detail Figure 1-3 with reference to the attached drawings.

[0018] The embodiment of the present application discloses an auxiliary mechanism for assembling a forklift handbrake. Refer to Figure 1 、 Figure 2 and Figure 3, including a frame 1 and a movable rod 21, a cavity is opened in the middle of one of the inner side walls of the frame 1, one end of the movable rod 21 is fixedly connected to a movable block 22, the movable block 22 is movably arranged inside the cavity, and the outer side wall of the movable block 22 is in contact with the inner surface of the inner cavity, a limiting member 23 is fixedly connected to the opening of the cavity, the movable rod 21 movably passes through the limiting member 23, and the limiting member 23 can be used to prevent the movable block 22 from escaping from the inner cavity, and the other end of the movable rod 21 is fixedly connected to a pressing block 24, the top and bottom ends of the pressing block 24 are respectively in contact with the inner top wall and the inner bottom wall of the frame 1, and the movable rod 21 can support the pressing block 24;

[0019] Reference Figure 1 , Figure 2 and Figure 3, one side of the frame body 1 is fixedly connected with a U-shaped block 3. The inner bottom wall of the U-shaped block 3 is fixedly connected with a lower tooth block 41. One end of the top of the lower tooth block 41 is fixedly connected with a limiting post 42. The outer surface of the limiting post 42 is movably sleeved with an upper tooth block 43. The teeth of the upper tooth block 43 are misaligned with the teeth of the lower tooth block 41, and one side of the upper tooth block 43 is attached to one of the inner side walls of the U-shaped block 3. The limiting post 42 can play a role in guiding and limiting the upper tooth block 43, so that the upper tooth block 43 can only move up and down inside the U-shaped block 3. A second spring 72 is movably sleeved on the outer surface of the middle part of the limiting post 42. The two ends of the second spring 72 are respectively in contact with the bottom end of the upper tooth block 43 and the top end of the lower tooth block 41. When the second spring 72 expands, it can push the upper tooth block 43 away from the limiting post 42, and at the same time make the top end of the upper tooth block 43 contact the inner top wall of the U-shaped block 3. Connecting blocks 44 are fixedly connected to both sides of the upper tooth block 43. Connecting rods 45 are fixedly connected to both sides of the movable rod 21. The two connecting blocks 44 are respectively connected to the two connecting rods 45 through two connecting lines 5. The two connecting lines 5 are each composed of a fiber rope 51 and two limiting blocks 52. Through holes are opened at the bottom ends of the two connecting blocks 44 and one ends of the two connecting rods 45. The two ends of the two fiber ropes 51 are respectively fixedly penetrated through the through holes opened at the bottom ends of the two connecting blocks 44 and one ends of the two connecting rods 45. The four limiting blocks 52 are respectively fixedly sleeved on the two ends of the two fiber ropes 51, which can prevent the two ends of the two fiber ropes 51 from slipping out of the four through holes. Guide wheels 6 for guiding the two connecting lines 5 are provided at one corner of each of the two sides of the U-shaped block 3. The two guide wheels 6 are each composed of a support shaft 61, a sealed bearing 62 and two retaining rings 63. The two support shafts 61 are respectively fixedly connected to one corner of each of the two sides of the U-shaped block 3. The inner bearing rings of the two sealed bearings 62 are respectively fixedly sleeved on the outer surfaces of the two support shafts 61. The two support shafts 61 can support the two sealed bearings 62. The four retaining rings 63 are respectively fixedly sleeved on the edges of the outer bearing rings of the two sealed bearings 62. One side of each of the two fiber ropes 51 is respectively in contact with the outer surface of the outer bearing ring of the two sealed bearings 62. In this way, the two sealed bearings 62 can support the two fiber ropes 51 during the rolling process and at the same time change the movement directions of the two fiber ropes 51. The four retaining rings 63 cooperate in pairs to limit the two fiber ropes 51, so that the two fiber ropes 51 can continuously contact the outer surfaces of the outer bearing rings of the two limiting blocks 52. When the user holds the frame body 1 with the hand and the user's hand tightly holds the pressing block 24, and then presses the pressing block 24 at the same time, at this time, the pressing block 24 pushes the movable rod 21 to move away from the U-shaped block 3. During this process, the movable rod 21 pulls the two connecting blocks 44 to move downward through the two connecting rods 45 and the two fiber ropes 51. The downward movement of the two connecting blocks 44 can pull the upper tooth block 43 to move downward, and then cooperate with the limiting post 42 to bite the steel wire, and then the steel wire in the steel lock can be pulled out.

[0020] Refer to Figure 1, Figure 2 and Figure 3 , inside a cavity formed in the middle of an inner sidewall of the housing 1, a first spring 71 is movably placed. One end of the first spring 71 abuts against the inner sidewall of the inner cavity, and the other end of the first spring 71 abuts against one side of the movable block 22. After the user slowly releases the pressing on the pressing block 24, at this time, the first spring 71 will expand and abut against the movable block 22 to move in the inner cavity, thereby pushing the movable rod 21 and the pressing block 24 to move in the direction of the U-shaped block 3, so as to play a role in resetting the pressing block 24. One end of the top of the housing 1 is fixedly connected with a hanging member 73. By buckling the hanging member 73 on the hook of the peripheral device, the housing 1 can be hung on the hook of the peripheral device.

[0021] The implementation principle of an auxiliary mechanism for a forklift handbrake assembly in an embodiment of the present application is as follows: during use, when the user holds the housing 1 with the hand and tightly holds the pressing block 24 with the hand, and at the same time presses the pressing block 24, at this time, the pressing block 24 pushes the movable rod 21 to move in the direction away from the U-shaped block 3. During this process, the movable rod 21 pulls two connecting blocks 44 to move downward through two connecting rods 45 and two fiber ropes 51. The downward movement of the two connecting blocks 44 can pull the upper tooth block 43 to move downward, and then cooperate with the limiting column 42 to bite the steel wire, so as to pull out the steel wire in the steel lock, thereby facilitating the placement of one end of the steel wire into the handbrake bayonet.
