Description

Technical Field

[0001] This utility model belongs to the field of screen technology, and in particular relates to a mobile construction screen. Background Technology

[0002] Construction sieves are essential tools used in the construction process for screening and filtering materials. They are typically made of materials such as metal wire (e.g., steel wire, stainless steel wire) or plastic, and come in different aperture sizes and mesh shapes to suit various construction needs. The main function of sieves is to remove impurities from building materials such as sand, gravel, and concrete, ensuring material quality and smooth construction. Therefore, existing sieves generally meet the needs of users, but the following problems still exist.

[0003] When using the screen, the operator places the screen on the frame, then uses a support frame to support the frame with the screen installed. The operator then uses the screen to sieve. Because the screen is large, it may be inconvenient for the operator to move it, which may make the operation of the screen cumbersome. Therefore, we propose a construction screen that is easy to move. Utility Model Content

[0004] This utility model provides a construction screen that is easy to move. By moving the fixing block toward the support frame, the distance between the fixing block and the support frame is reduced, which makes it easier for the operator to move the screen and improves the convenience of the operator in handling the screen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a movable construction screen, comprising a support frame, with fixing blocks arranged around the support frame, and extension columns fixed on the side where the fixing blocks are connected to the support frame, and each extension column having a storage groove on its surface. A guide rod fixed to the inner wall of the storage groove passes through the middle of each extension column, and the guide rod is snapped into the storage groove. A rotating block is fixed in the middle of the support frame, and a support rod is inserted into the middle of the rotating block. A rotating shaft fixed to the inner wall of the rotating block passes through the side of the support rod that is through the rotating block.

[0006] Furthermore, the support rod has a guide groove at the end away from the rotating block, and a stop block is embedded in the guide groove. A slide rod fixed to the inner wall of the guide groove passes through the middle of the stop block, and a third spring is wound around the surface of the slide rod. The two ends of the third spring abut against the inner wall of the guide groove and the surface of the stop block, respectively. A collar is fixed around the stop block and sleeved on the surface of the support rod, and a push plate is fixed at the end of the collar. A support groove is fixed on the side of the support rod near the rotating block.

[0007] Furthermore, the collar is provided with a circular through hole in the middle, and the circular through hole in the middle of the collar matches the cylindrical shape of the support rod.

[0008] Furthermore, the surface of each collar is provided with several sets of wavy grooves.

[0009] Furthermore, each of the extended columns has a spring groove at its end, and a first spring and a button are respectively installed inside the spring groove. The end of the button passes through the storage groove, and the two ends of the first spring abut against the two sets of buttons respectively.

[0010] Furthermore, each of the fixed blocks has a groove in the middle, and a second spring and a slider are respectively installed inside the groove. The two ends of the second spring abut against the inner wall of the groove and the surface of the slider, respectively. A traction rod fixed to the inner wall of the groove passes through the middle of the slider and the second spring. A clamping plate attached to the fixed block is fixed to the outer wall of the slider. A positioning block is fixed to the side of the clamping plate that is attached to the fixed block. The surface of the positioning block is fitted with a positioning groove opened on the fixed block.

[0011] The beneficial effects of this utility model are:

[0012] 1. This easily movable construction screen is equipped with a storage slot, an extension column, and a guide rod. When the operator pushes the fixing block, the fixing block pushes the extension column to slide within the storage slot, causing the support frame and the fixing block to move closer together. Once the support frame and the fixing block are close together, it is easy to change the length direction of the support frame and the fixing block, reducing the size of the combined support frame and the fixing block, thereby facilitating the operator's handling of the support frame and the fixing block and improving the operator's ease of handling.

[0013] 2. This easily movable construction screen is equipped with a groove, a collar, a push plate, a third spring, and a stop block. The operator pulls the collar, causing the stop block to move within the guide groove. The stop block compresses the third spring, causing it to elastically deform and avoid the stop block. This allows the collar to slide the push plate on the support rod surface. The operator then winds the screen onto the support rod surface. After releasing the collar, the collar no longer compresses the stop block via the third spring. The stop block then pushes the push plate through the collar, causing the push plate to fit onto the screen wound on the support rod surface, thus fixing the screen to the support rod and improving usability.

[0025] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings.

[0026] Example:

[0027] Please see Figure 1 - Figure 9A portable construction screen includes a support frame 1, with fixing blocks 2 around the support frame 1. Extension columns 4 are welded to the side of each fixing block 2 that connects to the support frame 1. Each extension column 4 has a storage groove 7 formed on the surface of the support frame 1. A guide rod 5, welded to the inner wall of the storage groove 7, passes through the middle of each extension column 4 and is snapped into the storage groove 7. Spring grooves 6 are formed at the ends of each extension column 4, and a first spring 12 and a button 11 are respectively installed inside the spring grooves 6. The end of the button 11 passes through the storage groove 7, and the two ends of the first spring 12 abut against the two sets of buttons 11. A rotating block 17 is welded to the middle of the support frame 1, and a support rod 15 is inserted into the middle of the rotating block 17. A rotating shaft 18, welded to the inner wall of the rotating block 17, passes through the side of the support rod 15 that passes through the rotating block 17. When the operator needs to reduce the size of the frame composed of the support frame 1 and fixing blocks 2, the operator first presses the button 11. The button 11 then... When the button 11 slides within the spring groove 6, it compresses the first spring 12, causing the first spring 12 to undergo elastic deformation. After the first spring 12 undergoes elastic deformation, it avoids the button 11, allowing the button 11 to enter the spring groove 6. The button 11 then moves out of the through hole on the surface of the storage groove 7, so that the button 11 is no longer fixed to the storage groove 7 and the extension column 4. The operator then pushes the fixing block 2, which causes the extension column 4 to slide within the storage groove 7. As the extension column 4 slides within the storage groove 7, the waist-shaped hole in the middle of the extension column 4 moves on the surface of the waist-shaped block that serves as the guide rod 5, restricting the extension column 4 and preventing it from falling out of the storage groove 7. After the extension column 4 is inserted into the storage groove 7, the support frame 1 and the fixing block 2 move closer together, making it easier for the operator to move the support frame 1 and the fixing block 2, thus improving the operator's ease of handling.

[0028] In other embodiments, a guide groove 23 is provided at the end of the support rod 15 away from the rotating block 17, and a stop block 22 is embedded in the guide groove 23. A sliding rod 25 welded to the inner wall of the guide groove 23 passes through the middle of the stop block 22, and a third spring 24 is wound around the surface of the sliding rod 25. The two ends of the third spring 24 abut against the inner wall of the guide groove 23 and the surface of the stop block 22, respectively. A collar 21 is welded around the stop block 22 and sleeved on the surface of the support rod 15. The middle of the collar 21 is set with a circular through hole, and the circular through hole in the middle of the collar 21 matches the cylindrical shape of the support rod 15. A push plate 19 is welded to the end of the collar 21. When the operator needs to disassemble the screen sheet for storage, the operator first holds the surface of the collar 21 with his hand, and then the operator pulls the collar 21. The collar 21 drives the stop block 22 to slide in the guide groove 23, and when the stop block 22 slides in the guide groove 23, the middle of the stop block 22 opens The circular through hole slides on the surface of the cylindrical slide bar 25, allowing the abutment 22 to move stably within the guide groove 23. As the abutment 22 moves, it compresses the third spring 24, causing the spring to elastically deform and then avoid the abutment 22. This allows the collar 21 to slide on the surface of the support rod 15, and the collar 21 moves the push plate 19. The operator then wraps the screen sheet around the surface of the support rod 15 and inserts one side of the screen sheet into the tray 16. After the operator releases the collar 21, the collar 21 no longer compresses the third spring 24 through the abutment 22, and the third spring 24 recovers its elastic deformation. The third spring 24 pushes the abutment 22, causing it to move, which in turn moves the collar 21. The collar 21 pushes the push plate 19 onto the surface of the screen sheet, thus fixing the screen sheet to the support rod 15 and improving the usability of storing the screen sheet.

[0029] In other embodiments, the surface of the collar 21 is provided with several sets of wavy grooves. When the operator pulls the collar 21 to move, after the operator holds the collar 21 with his hand, the several sets of wavy grooves on the surface of the collar 21 can increase the friction of the operator's hand holding the collar 21 and increase the stability of the operator pulling the collar 21.

[0030] In other embodiments, a groove 10 is provided in the middle of the fixing block 2, and a second spring 14 and a slider 8 are respectively provided inside the groove 10. The two ends of the second spring 14 abut against the inner wall of the groove 10 and the surface of the slider 8, respectively. A traction rod 9 welded to the inner wall of the groove 10 is passed through the middle of both the slider 8 and the second spring 14. A clamping plate 3 is welded to the outer wall of the slider 8 and attached to the fixing block 2. A positioning block 13 is welded to the side of the clamping plate 3 that is attached to the fixing block 2, and the surface of the positioning block 13 is fitted with a groove 10. In the positioning groove 20 on the fixed block 2, when the operator needs to place the screen sheet on the frame composed of the support frame 1 and the fixed block 2, the operator first pulls the clamping plate 3. The clamping plate 3 drives the slider 8 to slide in the slide groove 10. When the slider 8 slides in the slide groove 10, the circular through hole in the middle of the slider 8 slides on the cylindrical surface of the traction rod 9, so that the traction rod 9 pulls the slider 8 in the direction of movement, improving the stability of the slider 8's movement. Furthermore, when the slider 8 moves, the slider 8 squeezes and wraps around the traction rod 9. The second spring 14 on the surface of the guide rod 9 undergoes elastic deformation after being compressed by the slider 8. The second spring 14 avoids the slider 8, causing the clamping plate 3 to slide on the surface of the fixed block 2. As the clamping plate 3 moves, it causes the positioning block 13 to move out of the positioning groove 20, separating the clamping plate 3 from the fixed block 2. The operator then places the screen sheet between the inner wall of the clamping plate 3 and the surface of the fixed block 2. The operator then releases the clamping plate 3, and the clamping plate 3 no longer exerts pressure on the second spring through the slider 8. After being squeezed, the second spring 14 recovers its elastic deformation and pushes the slider 8 to move, causing the slider 8 to move the clamping plate 3. The inner wall of the clamping plate 3 moves toward the surface of the fixed block 2, and the clamping plate 3 moves the positioning block 13. After the positioning block 13 passes through the screen, the end of the positioning block 13 is inserted back into the positioning groove 20, so that the clamping plate 3 clamps one corner of the screen onto the surface of the fixed block 2, thereby making it convenient for the operator to install the screen onto the fixed block 2 and improving the convenience of the operator to install or remove the screen.
