Description

Technical Field

[0001] The present invention belongs to the technical field of door and window installation, and specifically relates to a positioning and measuring device for the installation of aluminum alloy doors and windows. Background Art

[0002] The main constituent material of aluminum alloy doors and windows is aluminum alloy, which makes them lightweight, strong, durable, and corrosion-resistant. Aluminum alloy is usually subjected to special surface treatments such as anodizing or powder coating to increase its aesthetic appeal and durability. When installing aluminum alloy doors and windows at the position of the required installation window, the door and window frame is placed in the opening, ensuring that they are horizontal, vertical, and flat. Bolts or expansion bolts are used to firmly fix the frame to the wall, and then sealants are added to fix the doors and windows. When marking and positioning the doors and windows in a building, positioning measurement is generally required so that users can measure the vertical center line of the doors and windows and confirm data such as the actual distance between the door and window opening and the door and window edge line for users to install the doors and windows.

[0003] Chinese Patent CN116876781A discloses an installation method for the auxiliary frame of aluminum alloy doors and windows, which relates to the technical field of the installation of the auxiliary frame of aluminum alloy doors and windows. The invention specifically includes: S1. Measuring the vertical center line of the doors and windows through a measuring device, and marking the actual distance between the door and window opening and the door and window edge line layer by layer; S2. After positioning the door and window opening, processing the door and window opening that needs to be processed; 3. Cutting materials according to the processing drawings of the steel auxiliary frame of the aluminum alloy doors and windows; S4. The installation and positioning of the steel auxiliary frame of the aluminum alloy doors and windows should be carried out according to the drawn door and window positioning lines; S5. Fixing the steel auxiliary frame of the aluminum alloy doors and windows to the wall; S6. After the aluminum alloy doors and windows are installed and fixed, the gaps are filled with cement mortar and then the finishing treatment is carried out. The invention is convenient for the staff to operate and improves work efficiency. By using the measuring device to mark the actual distance between the door and window opening and the door and window edge line, it is convenient for the staff to disassemble and reset the measuring device, and the actual distance between the door and window opening and the door and window edge line of each floor can be positioned, saving the time of setting up the theodolite.

[0004] In the installation method for the auxiliary frame of aluminum alloy doors and windows proposed in the above prior art, when measuring the data of the doors and windows, a measuring device is designed. Although the threaded sleeve can be rotated to adjust the distance of the positioning block, each threaded sleeve needs to be adjusted individually and adjusted multiple times to move the positioning block to a suitable position. Such operation is relatively cumbersome and has a large error, which is not convenient for the subsequent installation of the window. And because the connection between its transmission mechanism and connection mechanism can be bent, although it is convenient to carry, after a long time of use, a certain inclination angle will be generated at the bent part, which will cause a certain error in the measured data.

[0005] Therefore, we propose a positioning and measuring device for the installation of aluminum alloy doors and windows to facilitate the solution of the above-mentioned problems. Summary of the Invention

[0006] Aiming at the problems existing in the prior art that each threaded sleeve needs to be adjusted separately and adjusted multiple times to move the positioning block to a suitable position, and after the connecting parts of the transmission mechanism and the connecting mechanism are bent for a long time, resulting in certain errors in the measurement data, the purpose of the present invention is to provide a positioning and measuring device for the installation of aluminum alloy doors and windows.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows: A positioning and measuring device for the installation of aluminum alloy doors and windows, including a plurality of positioning blocks, an adjustment assembly, and a connection assembly. A telescopic ruler assembly is fixedly installed on the top of the positioning block; The adjustment assembly includes an adjustment box. A rotating shaft is rotatably connected through the inner wall of the adjustment box. First rotating rods are symmetrically rotatably connected through the side wall of the adjustment box. A first bevel gear is slidably connected to the side wall of the rotating shaft. A second bevel gear is fixedly connected to the side wall of the first rotating rod. Second rotating rods are symmetrically rotatably connected through the side wall of the adjustment box. A third bevel gear is fixedly connected to the side wall of the second rotating rod. A fourth bevel gear is slidably connected to the side wall of the rotating shaft. A circular plate is fixedly connected to the side wall of the first rotating rod. A first threaded sleeve is rotatably connected to the side wall of the circular plate. A first moving rod is threadedly connected to the inner wall of the first threaded sleeve. A second threaded sleeve is fixedly connected to the side wall of the second rotating rod. A second moving rod is threadedly connected to the inner wall of the second threaded sleeve; The connection assembly includes a first support block and a second support block. One end of the first moving rod is fixedly connected to the side wall of the adjacent first support block, and one end of the second moving rod is fixedly connected to the side wall of the adjacent second support block.

[0008] Furthermore, first telescopic rod assemblies are symmetrically and fixedly connected to the side wall of the first support block. The moving ends of the first telescopic rod assemblies are fixedly connected to the side wall of the adjacent positioning block.

[0009] Furthermore, second telescopic rod assemblies are symmetrically and rotatably connected to the side wall of the second support block. The moving ends of the second telescopic rod assemblies are fixedly connected to the side wall of the adjacent positioning block.

[0010] Furthermore, the first bevel gear is meshed and connected with the second bevel gear, and the fourth bevel gear is meshed and connected with the third bevel gear.

[0011] Furthermore, a rotating plate is fixedly connected to the top of the rotating shaft, and a handle is fixedly connected to the top of the rotating plate.

[0012] Furthermore, a threaded hole is opened on the top of the rotating plate, a bolt is threadedly connected inside the threaded hole, and a plurality of round holes are opened on the top of the adjustment box. One end of the bolt is inserted into the adjacent round hole.

[0013] Further, the side walls of the adjustment box are symmetrically penetrated and slidably connected with moving plates. The side walls of the moving plates are fixedly connected with racks, and the side walls of the rotating shafts are fixedly connected with small gears, and the small gears are meshed with the racks.

[0014] Further, a cylinder is sleeved on the side wall of the first rotating rod, and the side wall of the cylinder is fixedly connected with the side wall of the adjacent moving plate.

[0015] Further, two groups of sliding grooves are formed in the side wall of the rotating shaft. Sliders are slidably connected to the inner walls of the sliding grooves, and the side walls of the sliders are fixedly connected with the side walls of the adjacent first bevel gears or fourth bevel gears.

[0016] Further, a spring is fixedly connected to the inner wall of the sliding groove, and one end of the spring is fixedly connected with the side wall of the adjacent slider.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, by setting structures such as a rotating shaft, a first threaded sleeve, and a first telescopic rod assembly, the user only needs to rotate the rotating shaft to synchronously adjust the position of the positioning block. Thus, it is not necessary to perform relatively cumbersome steps to measure the size of the opening of the building window. Moreover, it is not necessary to adjust the levelness and perpendicularity in real time. After the position adjustment is completed, then rotate the bolt, and insert one end of the bolt into the adjacent round hole. Due to the threaded connection between the threaded hole and the bolt, when the bolt is not rotated, the bolt will not move out of the adjacent round hole. Thus, the rotating plate can be fixed again. If it is necessary to measure other doors and windows subsequently, the distance and relative position between the positioning blocks will not change due to accidental collision during the movement.

[0018] 2. In the present invention, by setting structures such as a first threaded sleeve, a round plate, and a second telescopic rod assembly, the user can conveniently bend the whole device, thereby reducing the space occupied by the whole device, and can also be conveniently reset, thus facilitating movement.

[0019] 3. In the present invention, by setting structures such as a cylinder, a small gear, and a rack, the cylinder can limit the rotation process of the first sleeve, so that the angle between the first threaded sleeve and the first rotating rod will not change. Thus, it is possible to prevent a certain inclination amplitude from occurring in the normal state after the bending part is bent for a long time. When the whole device is completed and needs to be placed, then manually push the cylinder to reset, thereby driving the rack to reset, so that the whole device can be bent, and the first sleeve can still be limited during subsequent use.

[0020] 4. In the present invention, by providing structures such as springs, sliders, and chutes, the user can adjust the position of the positioning block according to the required measurement ratio of the window opening, etc. When one set of positions of the first threaded sleeve or the second threaded sleeve is adjusted, but the other set of positions is not adjusted, the position of the other set can be continuously adjusted by rotating the rotating shaft. Thus, when the length and width of the door or window are different, the positioning block can still complete the positioning process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present invention will be further described below in conjunction with specific embodiments.

[0024] To solve the problem that the positioning block 1 needs to be adjusted multiple times to be moved to a suitable position, as Figure 1 -Figure 8 As shown: A positioning and measuring device for the installation of aluminum alloy doors and windows, including a plurality of positioning blocks 1, an adjusting assembly 2, and a connecting assembly 3. A telescopic ruler assembly 4 is fixedly installed on the top of the positioning block 1. The staff pulls out the telescopic end of the telescopic ruler assembly 4 so that the end face of the telescopic end of the telescopic ruler assembly 4 aligns with the door and window opening, facilitating the confirmation of the position of the door and window opening.

[0025] The adjusting assembly 2 includes an adjusting box 201. A rotating shaft 202 is rotatably connected through the inner wall of the adjusting box 201. First rotating rods 203 are symmetrically rotatably connected through the side wall of the adjusting box 201. A first bevel gear 204 is slidably connected to the side wall of the rotating shaft 202. A second bevel gear 205 is fixedly connected to the side wall of the first rotating rod 203. Second rotating rods 206 are symmetrically rotatably connected through the side wall of the adjusting box 201. A third bevel gear 207 is fixedly connected to the side wall of the second rotating rod 206. A fourth bevel gear 208 is slidably connected to the side wall of the rotating shaft 202. Thus, when the rotating shaft 202 rotates, it can drive the first bevel gear 204 and the fourth bevel gear 208 to rotate. When the second bevel gear 205 and the third bevel gear 207 rotate, they can drive the first rotating rod 203 and the second rotating rod 206 to rotate. A circular plate 210 is fixedly connected to the side wall of the first rotating rod 203. A first threaded sleeve 211 is rotatably connected to the side wall of the circular plate 210. A first moving rod 212 is threadedly connected to the inner wall of the first threaded sleeve 211. The first threaded sleeve 211 can rotate, thereby bending the adjusting assembly 2 for easy carrying by the user. A second threaded sleeve 214 is fixedly connected to the side wall of the second rotating rod 206. A second moving rod 215 is threadedly connected to the inner wall of the second threaded sleeve 214.

[0026] The connecting assembly 3 includes a first support block 301 and a second support block 302. One end of the first moving rod 212 is fixedly connected to the side wall of the adjacent first support block 301. One end of the second moving rod 215 is fixedly connected to the side wall of the adjacent second support block 302. Thus, when the first moving rod 212 and the second moving rod 215 move, they can drive the first support block 301 and the second support block 302 to move.

[0027] First telescopic rod assemblies 303 are symmetrically fixedly connected to the side wall of the first support block 301. The moving ends of the first telescopic rod assemblies 303 are fixedly connected to the side wall of the adjacent positioning block 1. Thus, the first telescopic rod assemblies 303 can expand and contract following the movement of the positioning block 1.

[0028] Second telescopic rod assemblies 304 are symmetrically rotatably connected to the side wall of the second support block 302. The moving ends of the second telescopic rod assemblies 304 are fixedly connected to the side wall of the adjacent positioning block 1. Thus, the second telescopic rod assemblies 304 can expand and contract following the movement of the positioning block 1, and the second telescopic rod assemblies 304 can bend.

[0029] The first bevel gear 204 and the second bevel gear 205 are meshed and connected, and the fourth bevel gear 208 and the third bevel gear 207 are meshed and connected. Thus, when the first bevel gear 204 rotates, it can drive the second bevel gear 205 to rotate, and when the fourth bevel gear 208 rotates, it can drive the third bevel gear 207 to rotate. Then, rotating the rotating shaft 202 can drive the first rotating rod 203 and the second rotating rod 206 to rotate.

[0030] A rotating plate 216 is fixedly connected to the top of the rotating shaft 202, and a handle 217 is fixedly connected to the top of the rotating plate 216. The user can drive the rotating plate 216 to rotate by rotating the handle 217, which facilitates the user to rotate the rotating plate 216.

[0031] A threaded hole 218 is formed in the top of the rotating plate 216, and a bolt 219 is threadedly connected inside the threaded hole 218. A plurality of round holes 220 are formed in the top of the adjusting box 201, and one end of the bolt 219 is inserted into an adjacent round hole 220. Thus, in the initial state, the bolt 219 limits the rotation process of the rotating plate 216, making the rotating plate 216 unable to rotate. When it is necessary to rotate the rotating plate 216, rotate the bolt 219. When one end of the bolt 219 is removed from the adjacent round hole 220, the rotating plate 216 can continue to rotate. When it is no longer necessary to rotate the rotating plate 216, screw the bolt 219, insert one end of the bolt 219 into the adjacent round hole 220, and the rotating plate 216 can be fixed again. Then, when measuring other doors and windows, the distance and relative position between the positioning blocks 1 will not change due to accidental collision during the movement.

[0032] When performing positioning measurement before installing aluminum alloy doors and windows, first rotate the bolt 219. One end of the bolt 219 moves out of the inner part of the round hole 220. At this time, the rotating plate 216 can rotate. Then, drive the rotating plate 216 to rotate through the handle 217. The rotating plate 216 drives the rotating shaft 202 to rotate. When the rotating shaft 202 rotates, it drives the first bevel gear 204 and the fourth bevel gear 208 to rotate. The first bevel gear 204 and the fourth bevel gear 208 drive the second bevel gear 205 and the third bevel gear 207 to rotate. The rotation of the second bevel gear 205 and the third bevel gear 207 drives the first rotating rod 203 and the second rotating rod 206 to rotate, and further drives the first threaded sleeve 211 and the second threaded sleeve 214 to rotate. Since one end positions of the first moving rod 212 and the second moving rod 215 are fixed, when the first threaded sleeve 211 and the second threaded sleeve 214 rotate, they will drive the first moving rod 212 and the second moving rod 215 to move, and further push the first support block 301 and the second support block 302 to move. When the first support block 301 and the second support block 302 move, they will drive the mobile ends of the first telescopic rod assembly 303 and the second telescopic rod assembly 304 to perform telescopic movement, and further move the position of the positioning block 1. So that the user only needs to rotate the rotating shaft 202 to synchronously adjust the position of the positioning block 1, and thus does not need relatively cumbersome steps to measure the size of the window opening of the building. Moreover, it is not necessary to adjust the levelness and perpendicularity in real time. After the position adjustment is completed, rotate the bolt 219 again and insert one end of the bolt 219 into the adjacent round hole 220. Due to the threaded connection between the threaded hole 218 and the bolt 219, when the bolt 219 is not rotated, the bolt 219 will not move out of the adjacent round hole 220, and thus the rotating plate 216 can be fixed again. If other doors and windows need to be measured subsequently, the distance and relative position between the positioning blocks 1 will not change due to accidental touch during the movement process.

[0033] When moving the entire device, for the convenience of movement, the user can bend the entire device by rotating the first threaded sleeve 211 and the second telescopic rod assembly 304, thereby reducing the space occupied by the entire device. And the staff can pull out the telescopic end of the telescopic ruler assembly 4 to align the end face of the telescopic end of the telescopic ruler assembly 4 with the door and window opening, which is convenient for confirming the position of the door and window opening.

[0034] To solve the problems that the lengths and widths of doors and windows are different and need to be measured according to the actual situation, and after the bent part of the entire device works for a long time, a certain inclination angle will be generated, which will cause a certain error in the measurement data, such as Figure 3 - Figure 8As shown in the figure: The side walls of the adjustment box 201 are symmetrically penetrated and slidably connected with moving plates 221. The side walls of the moving plates 221 are fixedly connected with racks 222. The side walls of the rotating shafts 202 are fixedly connected with pinions 213. The pinions 213 and the racks 222 are meshed and connected. Therefore, when the pinions 213 rotate, they will drive the racks 222 to move, and the racks 222 will drive the moving plates 221 to move. And because the moving plates 221 penetrate and move through the side walls of the adjustment box 201, the spatial distance that they can move is limited, so that they will not tilt during the moving process.

[0035] A cylinder 223 is sleeved on the side wall of the first rotating rod 203. The side wall of the cylinder 223 is fixedly connected with the side wall of the adjacent moving plate 221. Therefore, the moving plate 221 can drive the cylinder 223 to move, and the cylinder 223 can further limit the moving process of the moving plate 221. When the user is performing positioning measurement, in order to prevent the first threaded sleeve 211 and the second telescopic rod assembly 304 from being bent, the rotation process of the first threaded sleeve 211 is restricted, so that the whole device cannot be bent. When the user rotates the rotating shaft 202, the rotating shaft 202 drives the pinion 213 to rotate. The pinion 213 drives the rack 222 to move. The rack 222 drives the moving plate 221 to move. The moving plate 221 drives the cylinder 223 to move. And the cylinder 223 moves to the gap between the first threaded sleeve 211 and the round plate 210, wrapping part of the side wall of the first threaded sleeve 211 and the side walls of the round plate 210 and the first rotating rod 203, so that the first threaded sleeve 211 cannot rotate, thereby preventing a certain inclination amplitude from occurring under normal conditions after the bent part is bent for a long time.

[0036] Two groups of sliding grooves 224 are opened on the side walls of the rotating shafts 202. The inner walls of the sliding grooves 224 are slidably connected with sliders 225. The side walls of the sliders 225 are fixedly connected with the side walls of the adjacent first bevel gears 204 or fourth bevel gears 208. Therefore, the moving trajectories of the sliders 225 are restricted, and the moving trajectories of the first bevel gears 204 and the fourth bevel gears 208 are restricted, so that the first bevel gear 204 and the second bevel gear 205 can only slide along the side wall direction of the rotating shaft 202.

[0037] A spring 226 is fixedly connected to the inner wall of the sliding groove 224. One end of the spring 226 is fixedly connected to the side wall of the adjacent slider 225. The spring 226 has a certain elastic coefficient. Thus, under normal conditions, the first bevel gear 204 and the fourth bevel gear 208 can drive the second bevel gear 205 and the third bevel gear 207 to rotate without rotational failure. When the first support block 301 and the second support block 302 or the corresponding positioning block 1 abuts against the side wall of the window opening, and the other set of positioning blocks 1 has not reached the appropriate position yet, if the rotating shaft 202 is rotated at this time, the first moving rod 212 or the second moving rod 215 cannot move. At this time, the first threaded sleeve 211 or the second threaded sleeve 214 cannot rotate, thereby driving the second bevel gear 205 and the third bevel gear 207 not to rotate. Since the rotating shaft 202 is still in a rotating state, and the teeth of the first bevel gear 204, the second bevel gear 205, the third bevel gear 207 and the fourth bevel gear 208 are helical teeth, in order not to rotate anymore, the second bevel gear 205 and the third bevel gear 207 can push the first bevel gear 204 and the fourth bevel gear 208 to move, so that the first bevel gear 204 and the fourth bevel gear 208 are no longer engaged with the corresponding second bevel gear 205 and third bevel gear 207. The positioning block 1 that has not reached the position can still move, and thus the position of the positioning block 1 can be adjusted according to the required proportion of the window opening to be measured, etc. During this process, the first bevel gear 204 and the fourth bevel gear 208 drive the adjacent slider 225 to move, and the slider 225 compresses the corresponding spring 226. Thus, after the subsequent adjustment is completed, the first bevel gear 204 and the fourth bevel gear 208 can be reset under the elastic action of the spring 226, so that the first bevel gear 204 and the fourth bevel gear 208 can still be engaged with the corresponding second bevel gear 205 and third bevel gear 207 again.

[0038] When the length and width of the door or window to be measured are not the same, during the process of the user rotating the rotating shaft 202, the rotating shaft 202 drives the small gear 213 to rotate. The small gear 213 drives the rack 222 to move, the rack 222 drives the moving plate 221 to move, the moving plate 221 drives the cylinder 223 to move, and the cylinder 223 moves to the gap between the first threaded sleeve 211 and the circular plate 210, wrapping part of the side wall of the first threaded sleeve 211, the circular plate 210, and part of the side wall of the first rotating rod 203. When the first threaded sleeve 211 has a tendency to rotate, the side wall of the first threaded sleeve 211 abuts against the side wall of the cylinder 223. Then, the cylinder 223 restricts the rotation process of the first threaded sleeve 211, so that the angle between the first threaded sleeve 211 and the first rotating rod 203 does not change. Thus, it is prevented that after the bent part is bent for a long time, there is a certain inclination amplitude under normal conditions. When the whole device is completed and needs to be placed, manually push the cylinder 223 to reset, and then drive the rack 222 to reset, so that the whole device can be bent, and during subsequent use, the first threaded sleeve 211 can still be limited.
