[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:
[0027] This utility model provides an environmentally friendly and efficient rebar rust removal device, including a device body 1; the device body 1 is provided with a rust removal device shell 2, which facilitates the protection and support of various components. External threaded cylinders are provided at the top center of both the left and right end faces of the rust removal device shell 2, facilitating the assembly and locking of a locking cylinder 3 via threaded installation and rebar insertion / exit. The locking cylinder 3 is threaded onto the external threaded cylinder of the rust removal device shell 2, facilitating the fixing of a rubber frustum cylinder 4. The locking cylinder 3 has threads on its inner circumference, facilitating its assembly and disassembly via threads. A locking ring plate is provided on the inner circumference of the outer end of the locking cylinder 3, facilitating the locking of the pressure ring plate of the rubber frustum cylinder 4. The outer circumference of the locking cylinder 3 has a regular hexagonal structure, facilitating its assembly and disassembly via rotation using tools. The locking cylinder 3 has an inner... The device is secured with a rubber frustum cylinder 4, which facilitates the constriction of the inlet and outlet holes, allowing only the reinforcing bars to pass through. The rubber frustum cylinder 4 is axially aligned, facilitating the movement of the reinforcing bars from left to right. A clamping ring is provided on the outer circumference of the left end of the rubber frustum cylinder 4, which facilitates locking and fixing by assembling the locking cylinder 3. A bearing block with front and rear through holes is provided in the middle of the upper part of the left end face of the rust removal device housing 2, which facilitates the installation of the reinforcing bar guide plate 8 through the fixed shaft. A vertically penetrating limiting groove is provided in the middle of the left end face of the bearing block of the rust removal device housing 2, which facilitates the insertion and limiting of the semi-circular head plate of the reinforcing bar guide plate 8. A bearing plate with vertically penetrating holes is provided in the middle of the lower part of the left end face of the rust removal device housing 2, which facilitates the installation of the retractable rotating cylinder 5 through the bearing. Triangular plates are provided on both the front and rear of the bottom end face of the bearing plate of the rust removal device housing 2, which facilitates the strengthening of the load-bearing capacity.
[0028] The rust removal device housing 2 has a retractable rotating cylinder 5 mounted on its bearing plate via bearings. The retractable rotating cylinder 5 has threads on its inner circumference to facilitate the installation of the retractable lifting rod 6. The upper outer circumference of the retractable rotating cylinder 5 has a regular hexagonal structure for easy adjustment via tools. The lower outer circumference of the retractable rotating cylinder 5 has a bearing ring groove for easy installation via bearings. The retractable lifting rod 6 is threaded inside the retractable rotating cylinder 5, facilitating lifting and lowering via threaded engagement. The outer circumference of the retractable lifting rod 6 also has threads for easy installation of the retractable rotating cylinder 5. A through-hole is located in the middle of the top end face of the retractable lifting rod 6, facilitating the insertion of the semi-circular head of the retractable linkage rod 7 into the limiting position. A through-hole is located at the upper end of the retractable lifting rod 6, facilitating the installation of the retractable linkage rod 7 via a fixed shaft. Inside the limiting groove, a retractable linkage rod 7 is installed via a fixed shaft to facilitate support and movement of the rebar guide plate 8. Both ends of the retractable linkage rod 7 are provided with semi-circular heads with front and rear through holes, facilitating the rotation of the retractable linkage rod 7 via the fixed shaft. The rebar guide plate 8 is installed on the upper semi-circular head of the retractable linkage rod 7 via a fixed shaft, facilitating the rotation of the rebar guide plate 8. The top end face of the rebar guide plate 8 has a V-shaped groove that runs from left to right, facilitating the alignment of the rebar inside. The right side of the bottom end face of the rebar guide plate 8 is provided with a pair of semi-circular head blocks with front and rear through holes, facilitating the installation of the retractable linkage rod 7 via the fixed shaft. The right end of the bottom end face of the rebar guide plate 8 is provided with a semi-circular head plate with front and rear through holes, facilitating installation on the bearing block of the rust removal device housing 2 via the fixed shaft. The semi-circular head plate of the rebar guide plate 8 is installed on the bearing block of the rust removal device housing 2 via the fixed shaft, facilitating the retraction and unfolding of the rebar guide plate 8.
[0029] The specific usage and function of this embodiment are as follows:
[0030] In this utility model, such as Figure 1 As shown, the device body 1 is in the placement and use state. At this time, the V-shaped groove of the rebar guide plate 8 contains the rebar to be derusted, which facilitates the guidance and alignment of the rebar to be derusted through the rebar guide plate 8. This solves the problem that the process of aligning the rebar with the feed hole is time-consuming and affects the efficiency of rebar derusting. The rebar to be derusted passes through the inside of the rubber truncated cylinder 4 and runs horizontally through the inside of the derusting device shell 2. Both rubber truncated cylinders 4 enclose the rebar to be derusted, forming a dynamic sealing barrier. This solves the problem that rebar rust and dust can easily escape from the feed hole and pollute the working environment. Figure 1As shown, when the rebar guide plate 8 is flipped and retracted, the retraction rotating cylinder 5 is engaged with the retraction lifting rod 6 by rotating the tool. This causes the retraction lifting rod 6 to descend through the threaded engagement. The retraction lifting rod 6 then drives the lower end of the retraction connecting rod 7 to descend synchronously, thereby causing the upper end of the retraction connecting rod 7 to descend. The upper end of the retraction connecting rod 7 then drives the rebar guide plate 8 to flip and retract downwards, as shown in the diagram. Figure 5 As shown, this prevents the steel bar guide plate 8 from obstructing movement and placement.
[0031] Example 2: Unlike Example 1, the regular hexagonal structure of the assembly locking cylinder 3 can also be set as a regular heptagonal structure. This makes it necessary to use a special tool that works with the regular heptagonal structure to rotate the assembly locking cylinder 3, thus preventing non-staff members from rotating and disassembling the assembly locking cylinder 3.
[0032] Example 3: The difference from Example 1 is that the regular hexagonal structure of the retractable rotating cylinder 5 can also be set as a regular heptagonal structure. This makes the retractable rotating cylinder 5 require a special tool that works with the regular heptagonal structure to rotate, thus preventing non-staff members from rotating and adjusting the retractable rotating cylinder 5.
