Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel rod technology, specifically relating to a steel rod for positioning a wire mesh cage. Background Technology
[0002] During the production of autoclaved aerated concrete (AAC) panels, a steel mesh framework must be embedded within them to ensure panel strength. After embedding the steel mesh framework, positioning steel rods are used to position the mesh cage. To facilitate removal of the steel rods after use, they need to be coated with paraffin wax before insertion. However, during the coating process, the paraffin wax tends to accumulate downwards under gravity, resulting in less paraffin wax coating on the upper part of the steel rod, which affects subsequent removal. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a wire mesh cage positioning steel rod to solve the problems mentioned in the background art.
[0004] The technical solution adopted by this type of wire cage positioning steel rod to solve its technical problem is as follows:
[0005] A positioning steel rod for a wire mesh cage is provided, including a handle, an upper rod fixedly installed below the handle, a lower rod provided below the upper rod, an installation groove opened at the lower end of the upper rod, an installation rod fixedly installed at the top end of the lower rod, a first through hole opened on both sides of the upper rod, a second through hole opened on the installation rod, an insert rod inserted into the first through hole and the second through hole, and a drill bit fixedly installed on the lower rod.
[0006] Furthermore, the insertion rod includes a first insertion rod and a second insertion rod. A screw is fixedly installed at the end of the first insertion rod, and a screw hole is opened at the end of the second insertion rod corresponding to the screw. Several spring plates are provided on the outside of the screw, and the spring plates are fixedly installed on the first insertion rod respectively. The inner diameter of the first through hole is smaller than that of the second through hole.
[0007] Furthermore, a ring is fitted around the outer periphery of the screw, and spring plates are fixedly connected to the ring.
[0008] Furthermore, a spring is fitted onto the upper drill rod, and the spring is fixedly connected to the handle.
[0009] Furthermore, a collar fitted onto the upper rod is provided below the spring.
[0010] Furthermore, the drill bit is shaped like a triangle with its tip pointing downwards and a rectangular block connected above it, forming a vertically downward arrow shape.
[0011] Furthermore, the upper end of the mounting rod is rotatably mounted in the mounting groove via a bearing.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. In this utility model, a positioning steel rod for a wire mesh cage is used such that, when paraffin coating is required, the rod is removed and the lower rod is rotated. After the paraffin is coated, the steel rod is laid flat, and the paraffin is evenly solidified on the lower rod by rotating it at a uniform speed. After the paraffin has solidified, the rod is inserted into the second through hole through the first through hole to complete the paraffin coating on the lower rod. With this device, the paraffin can be evenly coated on the lower rod by rotating it, avoiding the difficulty of removing the rod due to uneven paraffin coating.
[0014] 2. In the example of this utility model, a positioning steel rod for a wire mesh cage is used by inserting the first and second rods into the second through holes from the first through holes on both sides, respectively. Rotating the second rod causes the screw to be screwed into the screw hole. The end of the second rod pushes the spring plate, causing the spring plate to bend. Since the inner diameter of the first through hole is smaller than that of the second through hole, the spring plate is stuck in the second through hole, thereby completing the fixing of the rod.
[0015] 3. In this utility model example, a positioning steel rod for a wire mesh cage can better contact the second insertion rod through a ring, making it easier to control the synchronous opening and closing of the spring plate.
[0016] 4. In this utility model example, a positioning steel rod for a wire mesh cage is supported on a saddle by a spring, which can apply an upward force to the handle, causing the insertion rod to press against the bottom of the saddle.
[0017] 5. In this utility model example, a positioning steel rod for a wire mesh cage can better hold the saddle by means of a collar.
[0018] 6. A positioning steel rod for a wire mesh cage according to this utility model example, with an arrow-shaped rod tip, can be easily inserted into the positioning hole of the steel mesh frame.
[0019] 7. In this utility model example, a positioning steel rod for a wire mesh cage is provided, wherein the mounting rod and the mounting groove are rotatably connected by a bearing, which can prevent the upper rod and the lower rod from separating. Attached Figure Description

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] Example 1: As Figure 1 and Figure 2 As shown, this embodiment provides a positioning steel rod for a wire mesh cage, including a handle 1. An upper rod 2 is fixedly installed below the handle 1, and a lower rod 3 is provided below the upper rod. An installation groove 4 is opened at the lower end of the upper rod 2, and an installation rod 5 is fixedly installed at the top end of the lower rod 3. First through holes 6 are opened on both sides of the upper rod 2, and a second through hole 7 is opened on the installation rod 5. Insertion rods 8 are inserted into the first through holes 6 and the second through holes 7. A drill bit 9 is fixedly installed on the lower rod 3.
[0027] In this embodiment, the insertion rod 8 includes a first insertion rod 81 and a second insertion rod 82. A screw 83 is fixedly installed at the end of the first insertion rod 81, and a screw hole 84 is opened at the end of the second insertion rod 82 corresponding to the screw 83. Several spring plates 85 are provided on the outside of the screw 83. The spring plates 85 are respectively fixedly installed on the first insertion rod 81. The inner diameter of the first through hole 6 is smaller than that of the second through hole 7.
[0028] In this embodiment, a ring 86 is fitted around the outer periphery of the screw 83, and spring plates 85 are fixedly connected to the ring 86.
[0029] In this embodiment, a spring 10 is mounted on the upper drill rod 2, and the spring 10 is fixedly connected to the handle 1.
[0030] In this embodiment, a collar 11 fitted onto the upper rod 2 is provided below the spring 10.
[0031] In this embodiment, the drill bit 9 is a triangle with its tip pointing downwards and a rectangular block connected above it, forming a vertically downward arrow shape.
[0032] In this embodiment, the upper end of the mounting rod 5 is rotatably mounted in the mounting groove 4 via a bearing.
[0033] In use, when paraffin coating is required, rotating the second insert 82 separates the first insert 81 and the second insert 82, allowing the lower drill rod 3 to rotate. After applying the paraffin, the drill rod is laid flat, and the paraffin is evenly solidified on the lower drill rod 3 by rotating it at a uniform speed. After the paraffin has solidified, the first insert 81 and the second insert 82 are inserted into the second through hole 7 from the first through hole 6 on both sides, respectively. Rotating the second insert 82 causes the screw 83 to be screwed into the screw hole 84. The end of the second insert 82 pushes the spring plate 85, causing the spring plate to bend. Since the inner diameter of the first through hole 6 is smaller than that of the second through hole 7... Spring plate 85 is inserted into the second through hole 7, thereby fixing the insertion rod 8. Then, the steel rod is inserted into the saddle, so that the rod tip 9 is inserted into the positioning hole of the steel mesh frame. Rotating the handle 1 can lock the rod tip 9. At the same time, during the rotation, the insertion rod 8 rotates synchronously and can be locked under the saddle. It is supported on the top of the saddle by spring 10 and collar 11. The steel mesh frame is kept in a suspended state by the elastic force of spring 10 itself. With this device, when applying paraffin wax, the paraffin wax can be evenly applied to the lower rod 3 by rotating it, avoiding the difficulty of removing the rod due to uneven paraffin wax application.
