Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically to an easily adjustable forklift fork tooth. Background Technology

[0002] Forklifts play a very important role in logistics systems and are the mainstay of material handling equipment. They are mainly used for loading, unloading, stacking, or short-distance transportation of pallets and / or goods. The forklift frame is the core component of the forklift, which is responsible for supporting and transferring the forks and loads.

[0003] A search revealed a utility model patent with Chinese patent publication number CN207827783U, which discloses a reach truck, including a forklift, a lifting rod connected to one side of the forklift and a top cavity connected to the top of the lifting rod, a rack rod connected to one side of the lifting rod, a cross plate connected to the top of the rack rod, a distance sensor on the surface of the cross plate and laser lights on both sides of the distance sensor, an alarm on the inner wall of the forklift and the alarm connected to the distance sensor, and doors connected to both sides of the door.

[0004] For some small forklifts, when supporting and lifting larger items, the small gap between the fork teeth may cause the items to tilt or even fall if there are bumps during the ride, indicating room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide an easily adjustable forklift fork tooth to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable forklift fork, including a mounting frame, on which two fork assembly is mounted externally, the two fork assembly being at the same level, each fork assembly including two hooks slidably sleeved on the outside of the mounting frame, the two hooks being fixedly connected by bolts, the two hook assembly being rotatably connected to a vertically arranged connecting column, the bottom outer wall of the connecting column being fixedly connected to a horizontally arranged fork body, and the top of the two connecting columns being equipped with the same drive component.

[0007] As a further preferred embodiment of this technical solution, a retaining ring is provided at the top of the outer circumference of the connecting column. The diameter of the retaining ring is larger than the diameter of the connecting column, and the two hooks are provided with limiting grooves that are adapted to the retaining ring.

[0008] As a further preferred embodiment of this technical solution, the drive assembly includes two worm gears coaxially fixed at one end of the top of two connecting columns, and a mounting seat is provided on the outer wall of the top of each of the four hook frames. The same worm is rotatably connected to the two mounting seats, and the two worms are arranged in opposite directions. The two worms mesh with the two worm gears respectively.

[0009] As a further preferred embodiment of this technical solution, the two worm gears are coaxially fixed to the same square telescopic rod at their close ends, and a knob is coaxially fixed to the outside of the square telescopic rod.

[0010] The tilt angle of the fork body can be adjusted as needed to increase the width of the two forks, making the supported items more stable. When the fork body is subjected to external force, the tension is applied to the limiting groove through the connecting post and the retaining ring. Since the retaining ring is engaged inside the limiting groove, it ensures that the connecting post will not move out of the mounting groove formed by the two hooks due to external force. Furthermore, because the retaining ring is ring-shaped, it ensures that the connecting post can still rotate normally. If the stability requirement is still not met when the distance between the two fork bodies is adjusted to the maximum, the square telescopic rod can be rotated by turning the knob. Due to the special structure of the square telescopic rod, the worm gear connected to it can be translated while rotating. The square telescopic rod drives the two worm gears to rotate, and the two worm gears drive the two worm wheels to rotate through meshing. The worm wheels drive the connecting post to rotate synchronously, and the end of the fork body closest to the outside flips outward, which can increase the support area and thus improve the support effect.

[0011] As a further preferred embodiment of this technical solution, an adjustment component is installed on both sides of the mounting frame. The adjustment component includes a hydraulic cylinder fixedly installed on the outer wall of one side of the mounting frame. A drive sleeve is fixedly connected to the output end of the hydraulic cylinder, and the drive sleeve is sleeved on the outside of the two hook frames.

[0012] To adjust the distance between the two fork tooth bodies, control the hydraulic cylinder mounted on the outside of the mounting bracket. The hydraulic cylinder drives the drive sleeve to move horizontally, and the two hook frames will be driven by the drive sleeve to move along the mounting bracket, thereby causing the position of the fork tooth bodies to move synchronously.

[0013] As a further preferred embodiment of this technical solution, each of the four corners of the mounting bracket is provided with a connecting plate, and each of the four connecting plates is provided with a through hole.

[0014] As a further preferred embodiment of this technical solution, a support ring is provided at the bottom of the outer circumference of each of the two connecting columns, and the diameter of the support ring is larger than the diameter of the connecting column. Both support rings are in contact with the inner wall of the bottom of the mounting bracket.

[0015] This utility model provides an easily adjustable forklift fork tooth, which has the following beneficial effects:

[0016] (1) By setting up a drive assembly and a drive component, the tilt angle of the fork tooth body can be adjusted as needed, thereby increasing the width of the two fork teeth and making the supported items more stable. When the fork tooth body is subjected to external force, the tension is applied to the limiting groove through the connecting column and the retaining ring. Since the retaining ring is engaged inside the limiting groove, it can ensure that the connecting column will not move out of the mounting groove composed of the two hooks due to external force. Furthermore, since the retaining ring is ring-shaped, it can ensure that the connecting column can still rotate normally. When the distance between the two fork tooth bodies is adjusted to the maximum, if the stability requirement is still not met, the square telescopic rod can be rotated by the knob. Due to the special structure of the square telescopic rod, it can ensure that the worm connected to it can also be translated while rotating. The square telescopic rod drives the two worms to rotate, and the two worms drive the two worm wheels to rotate through meshing. The worm wheels drive the connecting column to rotate synchronously, and the end of the fork tooth body near the outside flips outward, which can increase the support area and thus make the support effect better.

[0017] (2) By setting an adjustment component, if it is necessary to adjust the distance between the two fork tooth bodies, the hydraulic cylinder installed on the outside of the mounting frame is controlled. The hydraulic cylinder drives the drive sleeve to move in the horizontal direction. The individual composed of the two hook frames will be driven by the drive sleeve to move along the mounting frame, and the position of the fork tooth body will also be driven to move synchronously.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown in this embodiment, an easily adjustable forklift fork includes a mounting frame 1. Two fork tines 4 are mounted on the outside of the mounting frame 1. The two fork tines 4 are at the same level. The fork tines 4 include two hooks 401 that are slidably sleeved on the outside of the mounting frame 1. The two hooks 401 are fixedly connected by bolts. The two hooks 401 are rotatably connected to a vertically arranged connecting post 402. A horizontally arranged fork tine body 403 is fixedly connected to the bottom outer wall of the connecting post 402. The same drive component 5 is mounted on the top of the two connecting posts 402.

[0025] A retaining ring 405 is provided on the top of the outer circumference of the connecting column 402. The diameter of the retaining ring 405 is larger than the diameter of the connecting column 402, and the two hooks 401 are provided with limiting grooves 404 that are adapted to the retaining ring 405.

[0026] When the fork tooth body 403 is subjected to external force, the tension is applied to the limiting groove 404 through the connecting post 402 and the retaining ring 405. Since the retaining ring 405 is engaged inside the limiting groove 404, it can be ensured that the connecting post 402 will not move out of the mounting groove composed of the two hooks 401 due to external force. Furthermore, since the retaining ring 405 is arranged in a ring shape, it can be ensured that the connecting post 402 can still rotate normally.

[0027] like Figure 2 and Figure 4 As shown, the drive assembly 5 includes two worm gears 503 coaxially fixed at one end of the top of two connecting columns 402. Each of the four hook frames 401 has a mounting seat 501 on its top outer wall. The same worm 502 is rotatably connected to the two mounting seats 501, and the two worm gears 502 are arranged in opposite directions. The two worm gears 502 mesh with the two worm gears 503 respectively.

[0028] Two worm gears 502 are coaxially fixed to the same square telescopic rod 504 at their close ends, and a knob is coaxially fixed to the outside of the square telescopic rod 504.

[0029] If the stability requirement is still not met when the distance between the two fork tooth bodies 403 is adjusted to the maximum, the square telescopic rod 504 is rotated by the knob. Due to the special structure of the square telescopic rod 504, the worm gear 502 connected to it can be translated while rotating. The square telescopic rod 504 drives the two worm gears 502 to rotate. The two worm gears 502 drive the two worm wheels 503 to rotate through meshing. The worm wheels 503 drive the connecting column 402 to rotate synchronously. The end of the fork tooth body 403 near the outside flips outward, which can increase the support area and thus make the bearing effect better.

[0030] like Figure 1 and Figure 4As shown, an adjustment component 6 is installed on both sides of the mounting frame 1. The adjustment component 6 includes a hydraulic cylinder 601 fixedly installed on the outer wall of one side of the mounting frame 1. A drive sleeve 602 is fixedly connected to the output end of the hydraulic cylinder 601. The drive sleeve 602 is sleeved on the outside of the two hook frames 401.

[0031] To adjust the distance between the two fork tooth bodies 403, control the hydraulic cylinder 601 mounted on the outside of the mounting bracket 1. The hydraulic cylinder 601 drives the drive sleeve 602 to move horizontally. The individual consisting of the two hook frames 401 will be driven by the drive sleeve 602 to move along the mounting bracket 1, and thus the position of the fork tooth body 403 will also be driven to move synchronously.

[0032] like Figure 1 and Figure 2 As shown, each of the four corners of the mounting frame 1 is provided with a connecting plate 2, and each of the four connecting plates 2 is provided with a through hole. The mounting frame 1 and the forklift lifting structure can be connected through the connecting plates 2.

[0033] like Figure 1 and Figure 2 As shown, support rings 3 are provided at the bottom of the outer circumference of the two connecting columns 402, and the diameter of the support rings 3 is larger than the diameter of the connecting column 402. The two support rings 3 are in contact with the bottom inner wall of the mounting frame 1. When the fork body 403 carries the goods, the goods drive the connecting column 402 to move downward through the fork body 403. The support rings 3 outside the connecting column 402 will not easily move downward under the support of the mounting frame 1.

[0034] This utility model provides an easily adjustable forklift fork tooth, the specific working principle of which is as follows:

[0035] When the device is working, when the fork tooth body 403 is subjected to external force, the tension is applied to the limiting groove 404 through the connecting column 402 and the retaining ring 405. Since the retaining ring 405 is engaged inside the limiting groove 404, it can be ensured that the connecting column 402 will not move out of the mounting groove formed by the two hooks 401 due to external force. Furthermore, since the retaining ring 405 is ring-shaped, it can also ensure that the connecting column 402 can rotate normally. When the distance between the two fork tooth bodies 403 is adjusted to the maximum, if the stability requirement is still not met, the square telescopic rod 504 is rotated by the knob. Due to the special structure of the square telescopic rod 504, it can ensure that the worm gear 502 connected to it can also translate while rotating. The telescopic rod 504 drives two worm gears 502 to rotate. The two worm gears 502 mesh to drive two worm wheels 503 to rotate. The worm wheels 503 drive the connecting column 402 to rotate synchronously. The end of the fork tooth body 403 near the outside flips outward, which can increase the support area and thus improve the bearing effect. If it is necessary to adjust the distance between the two fork tooth bodies 403, the hydraulic cylinder 601 installed on the outside of the mounting frame 1 is controlled. The hydraulic cylinder 601 drives the drive sleeve 602 to move in the horizontal direction. The individual composed of the two hook frames 401 will be driven by the drive sleeve 602 to move along the mounting frame 1, and the position of the fork tooth body 403 will also be driven to move synchronously.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
