Description

Technical Field

[0001] This utility model belongs to the field of pin removal technology, and is particularly related to a manual forklift roller sales tool. Background Technology

[0002] Manual forklifts are dual-purpose vehicles for high-lift loading and unloading and short-distance transportation, featuring balanced lifting, flexible turning, and convenient operation. The rollers at the bottom of the manual forklift are mounted on a connecting shaft, which is fixed to the bottom of the forklift by a pair of elastic pins. Because the elastic pins on the connecting shaft bear heavy loads or frequent impacts, they are prone to breakage due to fatigue or wear, requiring timely replacement. The existing replacement method involves placing a push rod against one end of the elastic pin and then striking the push rod with a hammer to push the pin out. However, because the push rod is small, striking it can easily result in injury to the hand, and the elastic pin is subjected to a large instantaneous force when struck, causing it to easily bounce off the connecting shaft, posing a safety hazard. Therefore, an improvement is necessary. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides a manual forklift roller pusher tool that can push out a spring pin by turning a screw, thereby avoiding safety hazards.

[0004] To achieve the above objectives, the present invention employs the following technology: A manual forklift roller sales tool includes: The U-shaped frame includes a vertical section and a pair of horizontal sections perpendicular to one side of the vertical section. The top of the upper horizontal section has a threaded hole extending through its bottom, and the lower horizontal section has a vertical through hole. A screw is threaded into a threaded hole. Below the screw is a push rod that is axially aligned with the through hole, and the diameter of the push rod matches the diameter of the through hole.

[0005] Furthermore, the length direction of the transverse section of the U-shaped frame is perpendicular to the vertical section, and there is a pair of U-shaped frames arranged side by side along the width direction of the transverse section. The pair of U-shaped frames are connected by a connecting component. The top of the upper transverse section is provided with a threaded hole that penetrates to its bottom. Screws are threaded into the threaded holes. Below the screws, there is a push rod with the same axis as the screw. The lower transverse section is provided with a vertical through hole. The axis of the through hole is the same as the axis of the corresponding push rod. The diameter of the push rod matches the diameter of the through hole.

[0006] Furthermore, the connecting assembly includes a guide rod and an adjusting screw. The guide rod passes through a pair of vertical plates along the width direction of the horizontal plate. Both ends of the guide rod are equipped with limiting plates to prevent the vertical plates from detaching from the guide rod. One end of the adjusting screw is threadedly connected to one of the vertical plates, and the other end is rotatably connected to the other vertical plate via a rotating rod. A limiting ring is coaxially located at the end of the rotating rod near the screw, and a handwheel is located at the other end of the rotating rod. The handwheel and the limiting ring abut against both sides of the vertical plate, respectively. There is a pair of guide rods, and the adjusting screw is positioned between the pair of guide rods.

[0007] The beneficial effects of this utility model are as follows: 1. The spring pin can be pushed out by turning the screw to push the top rod, avoiding safety hazards when replacing the spring pin; 2. Align the through hole on one of the U-shaped brackets with a spring pin, and push the spring pin out by turning the screw. The push rod is still in the connecting shaft of the forklift roller. At this time, rotate the other U-shaped bracket to adjust its position to complete the alignment of the other through hole with the other spring pin, effectively improving the alignment efficiency.

[0014] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0015] This application provides a manual forklift roller sales tool, such as... Figures 1-2As shown, it includes a U-shaped frame 1, screws 2, and top rods 3.

[0016] Specifically, the U-shaped frame 1 includes a vertical section 101 and a pair of horizontal sections 102 perpendicularly disposed on one side of the vertical section 101. The top of the upper horizontal section 102 has a threaded hole extending through its bottom, and the lower horizontal section 102 has a vertical through hole 1021. The screw 2 is threaded into the threaded hole, and the push rod 3 is disposed below the screw 2. The axial direction of the push rod 3 is the same as that of the screw 2, and the axial direction of the push rod 3 is the same as that of the through hole 1021.

[0017] In actual use, first turn screw 2 to move it upward, then align the through hole 1021 with the pin to be removed, then insert the push rod 3 into the through hole 1021, and then turn screw 2 downward when screw 2 is turned, pushing the push rod 3 toward the pin to gradually push the pin out of the connecting shaft of the forklift roller. Then repeat the above steps to remove the other elastic pin on the connecting shaft of the forklift roller.

[0018] Because two spring pins need to be inserted into the connecting shaft of a forklift roller, both spring pins need to be removed and replaced. This requires aligning the pusher tool with the two spring pins sequentially, a cumbersome and time-consuming operation. In one embodiment, see [reference needed]. Figures 3-4 The length direction of the transverse segment 102 of the U-shaped frame 1 is perpendicular to the vertical segment 101, and there is a pair of U-shaped frames 1, which are arranged side by side along the width direction of the transverse segment. The pair of U-shaped frames 1 are connected by a connecting component. The top of the upper transverse segment 102 is provided with a threaded hole that penetrates its bottom. Screws 2 are threaded into the threaded holes. A push rod 3 with the same axis as the screw 2 is provided below the screw 2. A vertical through hole 1021 is provided on the lower transverse segment 102. The axis of the through hole 1021 is the same as the axis of the corresponding push rod 3. The diameter of the push rod 3 matches the diameter of the through hole 1021. Specifically, the distance between the two through holes 1021 is set to match the distance between the two pins inserted on the connecting shaft of the forklift roller. With this setting, the through hole 1021 on one of the U-shaped brackets 1 is aligned with a flexible pin. After the flexible pin is pushed out by turning the screw 2, the push rod 3 is still inside the connecting shaft of the forklift roller. At this time, rotating the other U-shaped bracket 1 to straighten its position can complete the alignment of the other through hole 1021 with the other flexible pin, effectively improving the alignment efficiency and thus improving the efficiency of disassembling the flexible pin.

[0019] For details, please refer to Figures 3-5The connecting assembly includes a guide rod 4 and an adjusting screw 5. The guide rod 4 passes through a pair of vertical plates along the width direction of the horizontal plate. Both ends of the guide rod 4 are equipped with limiting pieces 501 to prevent the vertical plates from detaching from the guide rod 4. One end of the adjusting screw 2 is threadedly connected to one of the vertical plates, and the other end of the adjusting screw 2 is rotatably connected to the other vertical plate via a rotating rod 6. A limiting ring 601 is coaxially provided at one end of the rotating rod 6 near the screw, and a handwheel 602 is provided at the other end of the rotating rod 6. The handwheel 602 and the limiting ring 601 abut against both sides of the vertical plate to limit the movement of the vertical plate in the width direction of the horizontal plate. More specifically, there is a pair of guide rods 4, and the adjusting screw 5 is located between the pair of guide rods 4. Because the distance between the connecting holes of the elastic pins on the connecting shaft of manual forklift rollers produced by different manufacturers may be different, this setting allows the adjusting screw 5 to be rotated to adjust the distance between the pair of U-shaped frames 1, thereby accommodating the disassembly of the elastic pins on the connecting shaft of manual forklift rollers produced by different manufacturers.

[0020] The above are only some of the embodiments listed in this application and are not intended to limit this application.
