Description

Technical Field

[0001] This utility model is a welded tray for steel mesh, belonging to the field of steel mesh processing. Background Technology

[0002] In the fabrication of reinforcing mesh, it is composed of alternating and welded straight and corrugated reinforcing bars. The specific operational procedure for this alternating arrangement is as follows: First, the straight reinforcing bars are placed one by one into pre-set V-grooves on a bracket to initially fix their positions. Next, multiple pressure blocks installed on the horizontal plate are used to press and secure the straight reinforcing bars, ensuring they will not shift during subsequent operations. Then, the corrugated reinforcing bars are inserted into the straight reinforcing bars, preparing for the subsequent welding process.

[0003] In this process, adjusting the distance between the horizontal plate and the bracket using a screw to limit and fix the reinforcing bars is a common structural design. Typically, the bracket has threaded holes machined to match the screw. After the reinforcing mesh is welded, the screw needs to be disengaged from the threaded hole to remove the finished product from between the horizontal plate and the bracket. However, in practice, it has been found that after the screw is separated from the threaded hole, welding slag, debris, and other impurities present at the construction site easily enter the threaded hole. This impurity hinders the reassembly of the screw, severely impacting work efficiency. Furthermore, cleaning the impurities from the threaded hole often requires significant time and effort, increasing processing costs and reducing overall production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a welded steel mesh tray to solve the problems mentioned in the background technology. This utility model prevents foreign objects from randomly entering the threaded connection part that mates with the screw on the tray.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welded steel mesh tray, comprising a bracket, with multiple supports evenly installed on the upper surface of the bracket. A V-shaped groove for storing straight steel bars is formed at the upper part of one side of each support. A horizontal plate is positioned directly above the bracket, and multiple pressure blocks for holding the straight steel bars are evenly installed on the lower surface of the horizontal plate. A screw is rotatably mounted on one end of the horizontal plate, and a guide hole is formed at the end of the horizontal plate away from the screw. A guide rod is inserted into the guide hole, and the lower end of the guide rod is connected to the bracket. A rectangular groove is formed by a downward indentation on the upper surface of the bracket away from the guide rod. A detachable rectangular block is installed at the upper part of the rectangular groove. A screw hole for cooperating with the screw is formed at the middle of the upper surface of the rectangular block. A vertically arranged spring is provided at the lower part of the rectangular groove, and a slider is provided at the upper end of the spring. The slider is slidably installed in the rectangular groove, and a plug for insertion into the screw hole is installed on the upper surface of the slider.

[0006] Furthermore, a first threaded blind hole is provided on one side of the rectangular block, and a notch communicating with the rectangular groove is provided on one side of the bracket. A screw is inserted into the notch, and one end of the screw is threaded into the first threaded blind hole.

[0007] Furthermore, an L-shaped plate is provided on the outside of the notch. The horizontal part of the L-shaped plate is connected and fixed to the bracket. The vertical part of the L-shaped plate has a round hole that is aligned with the notch. The screw passes through the channel formed by the round hole and the notch.

[0008] Furthermore, a vertical hole is provided at the end of the horizontal plate away from the guide hole. Limiting rings that slide in contact with the horizontal plate are provided on the upper and lower sides of the vertical hole. The limiting rings are sleeved on the screw and connected and fixed to the screw. A knob head is installed at the upper end of the screw.

[0009] Furthermore, a second threaded blind hole is provided on the side of the bracket away from the rectangular groove, and an external thread is machined on the outer surface of the lower end of the guide rod. The end of the guide rod with the external thread is threaded into the second threaded blind hole.

[0010] Furthermore, the bracket has an inverted "U" shaped structure, and two symmetrically arranged connecting ears for connecting the turntable are installed at the lower ends of the two vertical parts of the bracket. The upper surface of the connecting ears is provided with fixing holes for inserting bolts.

[0011] Furthermore, a handle is installed on the upper surface of the horizontal plate near the screw, and the handle has a "U" shaped structure.

[0012] The beneficial effects of this utility model are:

[0013] 1. The bracket is equipped with a detachable rectangular block with a screw hole. A slider and a plug are connected in the rectangular slot by a spring. When the screw is separated from the screw hole, the plug can be inserted into the screw hole under the action of the spring, effectively preventing welding slag, debris and other debris from entering the threaded connection part that mates with the screw. This avoids debris from hindering the reassembly of the screw, reduces the time and effort spent on cleaning debris, lowers processing costs and improves production efficiency.

[0014] 2. After inserting the rectangular block into the rectangular slot, screw the screw through the round hole and notch and into the first threaded blind hole to complete the assembly of the rectangular block and the bracket. If the screw cannot be loosened properly, use the gap between the L-shaped plate and the bracket to cut the screw, and then remove the rectangular block from the rectangular slot and replace it.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1This utility model provides a technical solution: a steel mesh welding tray, including a bracket 1, the bracket 1 having an inverted "U" shaped structure, and two symmetrically arranged connecting ears 2 for connecting to a turntable installed at the lower ends of the two vertical parts of the bracket 1. The upper surface of the connecting ears 2 has fixing holes 3 for inserting bolts. The connecting ears 2 are installed on the upper surface of the turntable using bolts, thus completing the assembly of the bracket 1 and the turntable. When the turntable is rotated, the bracket 1 also rotates, thereby facilitating the adjustment of the relative position of the steel mesh welding part and the personnel as needed.

[0023] See Figure 1 , Figure 3 and Figure 4 The bracket 1 has multiple supports 14 evenly installed on its upper surface. A V-shaped groove 16 for storing straight steel bars 4 is opened at the upper part of one side of the support 14. A horizontal plate 7 is provided directly above the bracket 1. Multiple pressure blocks 15 for pressing the straight steel bars 4 are evenly installed on the lower surface of the horizontal plate 7. The straight steel bars 4 are placed in the V-shaped groove 16, and then the pressure blocks 15 are inserted into the V-shaped groove 16 to press the straight steel bars 4, thereby achieving the clamping and limiting of the position of the straight steel bars 4. The pressure blocks 15 have a triangular structure. The triangular pressure blocks 15 and the V-shaped groove 16 cooperate with each other to facilitate the pressing of straight steel bars 4 of different thicknesses, so that the middle position of the straight steel bars 4 is in the V-shaped groove 16, which makes it convenient to simultaneously insert wavy steel bars 5 at both ends of the straight steel bars 4.

[0024] See Figures 1-4 A vertical hole 18 is provided at the end of the horizontal plate 7 away from the guide hole 26. Limiting rings 10 are provided on both the upper and lower sides of the vertical hole 18, which slide in contact with the horizontal plate 7. The limiting rings 10 are sleeved on the screw 9 and connected and fixed to the screw 9. A knob head 17 is installed on the upper end of the screw 9. Under the restriction of the limiting rings 10, the screw 9 and the horizontal plate 7 are rotated. A guide hole 26 is provided at the end of the horizontal plate 7 away from the screw 9. A guide rod 6 is inserted into the guide hole 26, and the lower outer surface of the guide rod 6 is machined. The bracket 1 has an external thread, and a second threaded blind hole 27 is provided on the side away from the rectangular groove 24. The end of the guide rod 6 with the external thread is threaded into the second threaded blind hole 27, which facilitates the disassembly and assembly of the guide rod 6 and the bracket 1. Tightening the screw 9 causes the horizontal plate 7 to move downward. Thus, the screw 9 and the guide rod 6 cooperate with each other to restrict the movement trajectory of the horizontal plate 7. A handle 8 is installed on the upper surface of the horizontal plate 7 near the screw 9. The handle 8 has a "U" shaped structure and serves as a carrier for gripping the horizontal plate 7.

[0025] See Figures 1-4The upper surface of the bracket 1 is recessed downwards on the side away from the guide rod 6 to form a rectangular groove 24. A detachable rectangular block 11 is installed in the upper part of the rectangular groove 24. A first threaded blind hole 20 is opened on one side of the rectangular block 11, and a notch communicating with the rectangular groove 24 is opened on one side of the bracket 1. A screw 12 is inserted into the notch, and one end of the screw 12 is threaded into the first threaded blind hole 20. An L-shaped plate 13 is provided outside the notch. The horizontal part of the L-shaped plate 13 is connected and fixed to the bracket 1. The vertical part of 13 has a round hole aligned with the notch. The screw 12 passes through the channel formed by the round hole and the notch, so that after the rectangular block 11 is inserted into the rectangular groove 24, the screw 12 passes through the round hole and the notch and is screwed into the first threaded blind hole 20, thus completing the assembly of the rectangular block 11 and the bracket 1. When the screw 12 and the rectangular block 11 cannot be loosened normally, the screw 12 is cut off by the gap between the L-shaped plate 13 and the bracket 1, and then the rectangular block 11 is removed from the rectangular groove 24 and replaced.

[0026] See Figures 1-4 A screw hole 19 is provided at the middle of the upper surface of the rectangular block 11 to cooperate with the screw 9. A vertically arranged spring 23 is provided at the lower part of the rectangular groove 24. A slider 22 is provided at the upper end of the spring 23. The slider 22 is slidably installed in the rectangular groove 24. A plug 21 for insertion into the screw hole 19 is installed on the upper surface of the slider 22. A detachable rectangular block 11 with a screw hole 19 is provided on the bracket 1. The slider 22 and the plug 21 are connected in the rectangular groove 24 by the spring 23. After the screw 9 separates from the screw hole 19, the plug 21 can be inserted into the screw hole 19 under the action of the spring 23. This effectively prevents welding slag, debris, and other foreign matter from entering the threaded connection part that mates with the screw 9, avoiding obstruction of screw 9 reassembly by foreign matter, reducing the time and effort spent on cleaning foreign matter, lowering processing costs, and improving production efficiency. Under the action of the spring 23's rebound force, the plug 21 will always be in contact with the end of the screw 9. During the process of removing the screw 9, the threads on the screw 9 will be sealed to the area in the screw hole 19 that is not sealed by the plug 21, i.e., the process of removing the screw 9... In this process, the threads on the screw 9 and the plug 21 work together to seal the screw hole 19. When the screw 9 is disengaged from the screw hole 19, the upper end of the plug 21 will protrude from the upper part of the screw hole 19. At the same time, the outer diameter channel at the top of the screw hole 19 is spiral-shaped and communicates with the outside space. Since the inner diameter of the screw hole 19 is blocked by the plug 21, no particles will enter the screw hole 19. When the screw 9 is screwed back into the screw hole 19, if small debris is found around the plug 21, the staff can simply blow it out. This reduces the difficulty compared to cleaning the small debris inside the screw hole 19.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
