A trolley wheel positioning jig

Abstract

This utility model discloses a wheel positioning clamp for a handcart, relating to the field of positioning clamp technology. It includes two wheel support frames, with multiple positioning sliders slidably connected between the inner walls of both sides of each wheel support frame. Each positioning slider has a central opening, and a support base is fixedly connected to the bottom of each positioning slider. This utility model, through the wheel support frames, places the handcart wheel on them, ensuring it is in close contact with the bottom of the handcart. By moving the positioning sliders, an inner sliding rod is inserted into the wheel mounting hole and contacts the bottom of the handcart. Then, the clamp and wheel positions are moved, allowing the inner sliding rod to insert into the wheel hole, thus positioning the wheel. Next, a fixing plate and a clamping slide plate are used to fix the wheel position. The wheel support frame is then slid down, exposing the mounting hole, thus facilitating the installation operation. This avoids tipping over the handcart, making the installation process safer.

Description

Technical Field

[0001] This utility model relates to the field of positioning clamp technology, specifically a positioning clamp for a handcart wheel. Background Technology

[0002] Currently, handcarts are widely used in logistics, transportation, and other fields. Existing handcarts include a base, handle, and wheels. The base has wheel holes and handle holes; the wheel holes are used to secure the wheels, and the handle holes are used to secure the handle. An existing handcart base and handcart (publication number: CN216833716U) exhibit at least the following defects during use:

[0003] In the above solution, the wheels are fixed to the trolley by the universal wheels and the inner wall of the wheel holes. In order to install the wheels, the trolley is often flipped up so that the bottom is facing up. However, the trolley base and body have considerable weight, which makes it troublesome to flip the trolley frequently. In addition, the trolley body may injure the staff during the flipping process, causing safety accidents. Therefore, a trolley wheel positioning clamp was developed. Utility Model Content

[0004] The main purpose of this utility model is to provide a wheel positioning clamp for handcarts, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A handcart wheel positioning clamp includes two symmetrically distributed wheel support frames. Multiple positioning sliders are slidably connected between the inner walls of both sides of each wheel support frame. Each positioning slider has a through-hole at its center. A support base is fixedly connected to the bottom side of each positioning slider. An outer sleeve is fixedly connected to the bottom side of each support base. A positioning spring is fixedly connected to the inner wall of the bottom side of each outer sleeve. An inner sliding rod is fixedly connected to the top of each positioning spring, and each inner sliding rod passes through the corresponding positioning slider through the corresponding through-hole.

[0007] Preferably, one of the wheel support frames is fixedly connected to a side pull slide, the surface of which is provided with a side pull slide groove, and the other wheel support frame is fixedly connected to a side pull slide rod, the outer edge of which is slidably connected to the inner wall of the side pull slide groove.

[0008] Preferably, each of the positioning sliders is fixedly connected to a traction rod on the side facing away from the other wheel support frame, and one end of each traction rod extends beyond the location of the side pull slide.

[0009] Preferably, a clamping back plate is fixedly connected to the top side of the side-pull slide, and a sliding column is slidably connected to the side of the clamping back plate facing the wheel support frame. A fixing clamp is fixedly connected to the top of the sliding column.

[0010] Preferably, the sliding column has a lifting groove on the side facing away from the clamping back plate, and a clamping slide plate is slidably connected between the inner walls of the lifting groove. A traction threaded rod is rotatably connected to the top of the clamping slide plate, and the traction threaded rod is screwed to the inner wall of the fixed clamping plate.

[0011] Preferably, a lifting handle is fixedly connected to the side of the clamping back plate facing away from the sliding column, and a limiting top strip is fixedly connected to the top side of the clamping back plate.

[0012] Preferably, a wheel body is placed on the top of the two wheel support brackets. The top side of the wheel body has multiple mounting holes, and the top of the inner slide rod is inserted between the inner walls of the mounting holes.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting up the wheel support bracket, the trolley wheel is placed on it and pressed tightly against the bottom of the trolley. By moving the positioning slider, the inner slide rod is inserted into the wheel mounting hole and contacts the bottom side of the trolley. Then, the position of the clamp and the wheel is moved so that the inner slide rod is inserted into the wheel hole, thereby positioning the wheel. Then, the wheel position is fixed by fixing the clamp plate and the clamping slide plate. The wheel support bracket is then slid down to expose the mounting hole, thus allowing the installation work to be carried out. This avoids the trolley body from tipping over, making the installation process safer. Attached Figure Description

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A handcart wheel positioning clamp includes two symmetrically distributed wheel support frames 101. Multiple positioning sliders 201 are slidably connected between the inner walls of both sides of each wheel support frame 101. In this embodiment, a ring of supporting slide plates 203 is fixedly connected to the edge of each positioning slider 201, and the supporting slide plates 203 are slidably connected to the inner wall of the wheel support frame 101. Each positioning slider 201 has a through-hole at its center. A supporting base frame 204 is fixedly connected to the bottom side of each positioning slider 201. An outer sleeve 205 is fixedly connected to the bottom side of each supporting base frame 204. A positioning spring 206 is fixedly connected to the inner wall of the bottom side of each outer sleeve 205. An inner slide rod 207 is fixedly connected to the top of each positioning spring 206, and each inner slide rod 207 passes through the corresponding positioning slider 201 via the corresponding through-hole. Each inner slide rod 207 has a supporting ball bearing 208 at its top. In this embodiment, a wheel body 401 is placed on the top of the two wheel support frames 101. The top side of the wheel body 401 has multiple mounting holes 402, and the top of the inner slide rod 207 is inserted between the inner walls of the mounting holes 402. The supporting ball bearing 208 rolls on the bottom surface of the handcart. When the inner slide rod 207 moves to the position of the wheel hole, it will be inserted into it, thereby fixing the position of the wheel body 401.

[0025] One of the wheel support brackets 101 has a side pull slide 104 fixedly connected to one side, and the surface of the side pull slide 104 has a side pull groove 102. The other wheel support bracket 101 has a side pull rod 103 fixedly connected to one side, and the outer edge of the side pull rod 103 is slidably connected to the inner wall of the side pull groove 102. Each positioning slider 201 has a traction rod 202 fixedly connected to the side facing away from the other wheel support bracket 101, and one end of each traction rod 202 extends beyond the position of the side pull slide 104. In this embodiment, the position between the two wheel support brackets 101 can be adjusted to accommodate wheel bodies 401 of different sizes. The position of the positioning slider 201 is adjusted by the traction rod 202 so that the corresponding inner slide rod 207 is inserted between the inner walls of the corresponding mounting hole 402.

[0026] A clamping back plate 301 is fixedly connected to the top side of the side-pull slide 104. A sliding column 302 is slidably connected to the side of the clamping back plate 301 facing the wheel support frame 101. A fixing clamp 305 is fixedly connected to the top of the sliding column 302. A lifting slide groove is opened on the side of the sliding column 302 facing away from the clamping back plate 301. A clamping slide plate 304 is slidably connected between the inner walls of the lifting slide groove. A traction threaded rod 303 is rotatably connected to the top of the clamping slide plate 304. The traction threaded rod 303 is screwed to the inner wall of the fixing clamp 305. A lifting handle 308 is fixedly connected to the side of the clamping back plate 301 facing away from the sliding column 302. A limiting top strip 307 is fixedly connected to the top side of the clamping back plate 301.

[0027] In this embodiment, when the worker holds the clamp by pulling the handle 308, the sliding column 302 naturally slides down to be flush with the top side of the bottom wheel support frame 101. At this time, the wheel body 401 and the inner slide rod 207 are adapted, and the wheel body 401 and the wheel hole are adapted. Then, the top side of the clamping slide plate 304 contacts the bottom side of the wheel body 401. By rotating the handle 306, the traction threaded rod 303 is rotated, so that the fixing clamping plate 305 and the clamping slide plate 304 are brought closer, clamping the wheel body 401 and the trolley base plate. At this time, the wheel support frame 101 and the wheel body 401 are disengaged, making it convenient to fix the wheel body 401.

[0028] It should be noted that this utility model, as a handcart wheel positioning clamp, is used by placing the handcart wheel body 401 on the wheel support frame 101 and keeping it in close contact with the bottom of the handcart. By moving the positioning slider 201, the inner slide rod 207 is inserted into the wheel mounting hole 402 and contacts the bottom side of the handcart. Then, the position of the clamp and the wheel body 401 is moved so that the inner slide rod 207 is inserted into the wheel hole, thereby positioning the wheel. Then, the wheel position is fixed by the fixing clamp 305 and the clamping slide plate 304. The wheel support frame 101 is then slid down to expose the mounting hole 402, thus enabling the installation operation. This avoids flipping the handcart body and makes the installation process safer.
