Specific embodiments

[0020] In order to further understand the invention content, features and effects of the present utility model, the following embodiments are cited and described in detail with reference to the accompanying drawings as follows.

[0021] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1 to 4 shown, a steel bar cutting device for construction engineering provided by an embodiment of the present utility model includes a processing table 1, a positioning seat 2, a rotating seat 3, a fixing groove 4 and a connection structure 5. A fixing frame 101 is fixedly connected to the bottom of the processing table 1. The rear side of the top of the processing table 1 is rotatably connected to a rotating handle 102 through a rotating shaft. A cutting machine 103 is fixedly connected to the top of the rotating handle 102. Processing grooves 104 are respectively opened on the left and right sides of the top of the processing table 1. The left and right sides of the inner walls of the two processing grooves 104 are respectively rotatably connected to main screw rods 105. The outer surfaces of the two main screw rods 105 are respectively threadedly connected to processing blocks 106. The outer surfaces of the two processing blocks 106 are respectively slidably connected to the inner walls of the two processing grooves 104. The tops of the two processing blocks 106 are respectively fixedly connected to a positioning seat 2. The rear side of the top of the positioning seat 2 is rotatably connected to a rotating seat 3 through a rotating shaft. A plurality of spring rods 6 are respectively fixedly connected to the inner walls of the positioning seat 2 and the rotating seat 3. One ends of the plurality of spring rods 6 close to each other are respectively fixedly connected to rubber blocks 601. The bottom of the front of the rotating seat 3 is fixedly connected to a positioning block 7. A positioning groove 701 is opened at the bottom of the positioning block 7. A fixing groove 4 is opened at the top of the front of the positioning seat 2. The positioning block 7 is inserted into the fixing groove 4. A moving groove 8 is opened on the front of the positioning seat 2. A connection structure 5 is arranged on the inner wall of the fixing groove 4.

[0023] Refer to Figure 3 and Figure 4, the connecting structure 5 includes a moving block 9. The moving block 9 is arranged on the front surface of the positioning seat 2. The outer surface of the moving block 9 is slidably connected to the inner wall of the moving groove 8. A pressing block 10 is fixedly connected to the front surface of the moving block 9, and a moving rod 11 is arranged on the back surface of the moving block 9.

[0024] With the above solution: by setting the moving block 9, when the pressing block 10 is pushed downward, it can drive the moving block 9 to slide downward in the moving groove 8, so as to synchronously drive the moving rod 11 to move downward.

[0025] Reference Figure 4 , the moving rod 11 is arranged on the inner wall of the fixed groove 4. The front surface of the moving rod 11 is fixedly connected to the back surface of the moving block 9. Two linkage arms 12 are sleeved on the outer surface of the moving rod 11.

[0026] With the above solution: by setting the moving rod 11, when the moving block 9 moves, it can drive the moving rod 11 to move downward in the fixed groove 4. Thus, the moving rod 11 moves and can drive the two linkage arms 12 to move respectively.

[0027] Reference Figure 4 , the two linkage arms 12 are arranged in a front-back staggered manner respectively. Linkage grooves 13 are respectively formed on the surfaces of the two linkage arms 12. The inner walls of the two linkage grooves 13 are respectively fitted with the outer surface of the moving rod 11. A sliding rod 14 is arranged at the top of the two linkage arms 12. Fixed arms 15 are respectively fixedly connected to the tops of the two linkage arms 12.

[0028] With the above solution: by setting the linkage arms 12, when the moving rod 11 moves downward, it can simultaneously press the inner walls of the two linkage grooves 13 to drive the two linkage arms 12 to move closer in a staggered manner, so as to drive the two fixed arms 15 to move in cooperation with the sliding rod 14.

[0029] Reference Figure 4 , the two ends of the sliding rod 14 are respectively fixedly connected to the left and right sides of the inner wall of the fixed groove 4. The sliding rod 14 cooperates with the two fixed arms 15.

[0030] With the above solution: by setting the sliding rod 14, the sliding rod 14 can provide a horizontal stroke, so that the two fixed arms 15 can slide horizontally on the surface of the sliding rod 14.

[0031] Reference Figure 4 , the middle parts of the two fixed arms 15 are respectively slidably connected to the outer surface of the sliding rod 14. A fixed spring 16 is fixedly connected to the side of the two fixed arms 15 close to each other. The fixed spring 16 is sleeved on the surface of the sliding rod 14. Fixed blocks 17 are respectively fixedly connected to the tops of the two fixed arms 15.

[0032] Adopting the above solution: By setting the fixed arms 15, the two fixed arms 15 can be respectively driven by the two linkage arms 12 to slide close to each other on the surface of the sliding rod 14, and the compression of the fixed spring 16 is squeezed. The two fixed arms 15 slide and then drive the two fixed blocks 17 to move closer respectively.

[0033] Reference Figure 4 , the two fixed blocks 17 are respectively fixedly connected to the mutually remote ends of the tops of the two fixed arms 15, and the mutually remote ends of the two fixed blocks 17 are respectively inserted into the inner wall of the positioning groove 701.

[0034] Adopting the above solution: By setting the fixed blocks 17, the two fixed blocks 17 can be respectively disengaged from the positioning groove 701 when moving closer, so as to release the fixed limit on the positioning block 7, thereby releasing the fixed connection between the rotating seat 3 and the positioning seat 2.

[0035] The working principle of the present utility model:

[0036] During use, the two ends of the steel bar to be cut are respectively placed on the positioning seat 2, and then the rotating seat 3 is rotated, and the positioning block 7 is driven to be inserted into the fixing groove 4. During the downward movement of the positioning block 7, the two fixed blocks 17 can be respectively squeezed to move closer, and the sliding of the two fixed arms 15 is driven to be closer. When the positioning block 7 is completely inserted into the positioning groove 701, the fixed spring 16 pulls the two fixed arms 15 to slide away, so as to drive the two fixed blocks 17 to be respectively inserted into the positioning groove 701 to fix and limit the positioning block 7. Repeat this method to fix another rotating seat 3 and the positioning seat 2, so that the spring rod 6 and the rubber block 601 cooperate to fix and limit the two ends of the steel bar. Subsequently, the cutting machine 103 is moved by rotating the handle 102 to cut the steel bar, and the processing block 106 can be driven to move in the processing groove 104 by rotating the main screw rod 105, so as to drive the positioning seat 2 to move, thereby adapting to steel bars of different lengths. After cutting, the pressing block 10 can be pressed down, so that it drives the moving block 9 to move downward in the moving groove 8, and drives the downward movement of the moving rod 11. When the moving rod 11 moves downward, it simultaneously squeezes the two linkage grooves 13, so as to drive the two linkage arms 12 to move closer in a staggered manner, and drive the two fixed arms 15 to slide closer on the surface of the sliding rod 14, and at the same time compress the fixed spring 16. The two fixed arms 15 then drive the two fixed blocks 17 to move closer, so that the two fixed blocks 17 are respectively disengaged from the positioning groove 701 to release the fixed limit on the positioning block 7. Subsequently, the rotating seat 3 can be turned upward, driving the positioning block 7 to disengage from the fixing groove 4, and the cut steel bar can be removed.

[0037] In summary, for the steel bar cutting device of the construction project, through the coordinated operation of the processing table 1, positioning seat 2, rotating seat 3, fixed groove 4 and connection structure 5, it solves the problem that during the cutting process of steel bars, the un-fixed steel bars are prone to shaking or deviation during cutting, resulting in inaccurate cutting dimensions and length deviation. Such deviation may affect subsequent construction and installation, and even affect the stability and safety of the entire structure.
