[0002] The search application number 201921619536.6 discloses a metal door and window level measuring device, including a main body, both ends and the middle of the main body are provided with a level bubble, both ends of the main body are provided with a support rod and an adjustment disk, the adjustment disk is connected to the adjustment device and the adjustment disk is connected to the support rod through the adjustment device. Preferably, the adjustment device includes a screw rod, one end of the screw rod is connected to the adjustment disk and the other end is connected to the limit disk, and a threaded sleeve is threadedly connected to the screw rod.

[0003] During use, a metal door and window levelness measuring device in this patent application adjusts the distance represented by the unit scale by adjusting the pitch of the screw rod and the inclination angle of the inclined surface of the two wedge blocks. Because the spirit level will be located in the middle after a certain length after the support rod is extended, the scale read out at this time is the height that needs to be adjusted to the position of the support rod. However, during such use, when the support rod is extended, one end of the main body will be lifted away from the crossbeam of the door and window being measured. At this time, the device is completely dependent on the user's hand for support, which makes the device easy to tilt during the measurement process, thereby affecting the measurement accuracy of the device and reducing the practicability of the device. For this reason, we propose a building energy-saving metal door and window levelness measuring device. Utility Model Content

When in use, the device is placed on the beam of the door and window to be measured and the measuring base plate is placed in contact with the surface of the beam. The level bubble assembly is used to preliminarily determine which end the beam is tilted to. The adjusting knob on the measuring device body at the same side as the tilted end of the beam drives the adjusting threaded rod to rotate, forcing the hexagonal support rod threadedly connected through the adjusting threaded hole to move downward along the inside of the hexagonal sliding sleeve. Since the bottom end of the hexagonal support rod contacts the bottom end of the adjusting threaded hole, one end of the measuring device body is forced to rotate upward with the rotating shaft rod on the other end of the measuring device body as the axis until it is horizontal, and the level bubble on the level bubble assembly is located in the middle position. At the same time, one end of the measuring device body drives the rotating shaft at the same side. The rod slides upward along the two arc-shaped slide grooves on the limit bracket. According to the principle of threaded transmission, the angle of rotation of the threaded rod is proportional to the extended length of the hexagonal support rod. Therefore, the extended length of the hexagonal support rod can be calculated by adjusting the rotation angle of the threaded rod, and the extended length of the hexagonal support rod can be directly read through the distance pointer and the distance scale, that is, the height of the hexagonal support rod that needs to be adjusted. The above operation is simple and practical, and the structure is reasonable and compact. During the measurement process, the measuring base plate is always in contact with the surface of the beam, and the measuring base plate is connected to the internal sliding of the measuring device body through the limit bracket to improve the structural stability between the two, thereby improving the stability of the device itself during the measurement process, so as to avoid the device from tilting during the measurement process to affect the accuracy of the measurement result, thereby improving the practicality of the device.

[0021] 2. This device for measuring the horizontality of energy-saving metal doors and windows in buildings is provided with a reset spring. In the initial state, two limit brackets form a downward pulling force on two rotating shafts through the reset spring and the limit slip ring, so that the main body of the measuring device and the measuring base plate can maintain a close contact, so as to avoid the relative sliding between the main body of the measuring device and the measuring base plate when the device is not in use, thereby avoiding collision and accelerating damage to the device, thereby improving the practicality of the device.

The left and right ends of the top wall surface of the measuring base plate 12 are fixedly installed with two limit brackets 13 slidably connected to the inside of the measuring device body 10. The two limit brackets 13 are both U-shaped. Rotating mechanisms are arranged inside the two limit brackets 13. The rotating mechanisms include two arc-shaped sliding grooves 14 symmetrically penetrating the wall surfaces on the front and rear sides of the inner cavity of the limit bracket 13 and a sliding The rotating shaft 15 is connected to the bottom end of the two arc-shaped slide grooves 14, and the front and rear ends of the rotating shaft 15 are fixedly connected to the corresponding positions of the front and rear side walls of the inner cavity of the measuring device body 10. The center of the two arc-shaped slide grooves 14 on the limit bracket 13 at the left position is on the same straight line with the axis of the rotating shaft 15 at the right position. The center of the two arc-shaped slide grooves 14 on the limit bracket 13 at the right position is on the same straight line with the axis of the rotating shaft 15 at the left position. A reset spring 16 is fixedly installed in the middle of the inner cavity bottom wall of the two limit brackets 13. The two reset springs 16 are fixedly installed in the middle of the inner cavity bottom wall of the two limit brackets 13. 6 is fixedly connected to the top of two limit slip rings 17, and the two limit slip rings 17 are respectively rotatably connected to the two rotating shafts 15 located in the middle of one side wall surface inside the two limit brackets 13. Two hexagonal sliding sleeves 18 are fixedly inserted at the left and right sides of the top wall surface of the inner cavity of the measuring device body 10. A measuring mechanism is arranged inside the two hexagonal sliding sleeves 18. The measuring mechanism includes a hexagonal support rod 19 that is slidably connected to the inside of the hexagonal sliding sleeve 18 and can be adjusted in height, and an adjusting threaded rod 20 that is rotatably connected to the middle of the top wall surface of the inner cavity of the hexagonal sliding sleeve 18. The bottom end of the hexagonal support rod 19 is in conflict with the top wall surface of the measuring plate 12. The hexagonal The top wall of the support rod 19 is provided with an adjusting threaded hole 21 which is matched with the adjusting threaded rod 20. The bottom end of the adjusting threaded rod 20 is threadedly connected to the inside of the adjusting threaded hole 21. The top end of the adjusting threaded rod 20 passes through the middle of the top wall of the hexagonal sliding sleeve 18 and extends to the outside and is fixedly installed with an adjusting knob 22. A distance pointer 24 is provided at the edge of the top wall of the adjusting knob 22.

The distance scales 23 correspond to and match the distance pointer 24, and the distance scales 23 and the adjusting threaded rod 20 are on the same axis.

[0030] The working principle of the utility model is as follows: when in use, the device is placed on the beam of the door and window to be measured and the measuring base plate 12 is placed in contact with the surface of the beam. The level bubble assembly 11 is used to preliminarily determine which end the beam is inclined to. The adjusting knob 22 on the same side of the inclined end of the beam on the measuring device body 10 is rotated to drive the adjusting threaded rod 20 to rotate, forcing the hexagonal support rod 19 threadedly connected through the adjusting threaded hole 21 to move downward along the inside of the hexagonal sliding sleeve 18. Since the bottom end of the hexagonal support rod 19 contacts the bottom end of the adjusting threaded hole 21, the adjusting threaded rod 20 is rotated. The measuring device body 10 is touched, thereby forcing one end of the measuring device body 10 to rotate upward with the rotating shaft 15 on the other end of the measuring device body 10 as the axis until it is in a horizontal state, and the level bubble on the level bubble assembly 11 is located in the middle position. At the same time, one end of the measuring device body 10 drives the rotating shaft 15 at the same side to slide upward along the two arc-shaped slide grooves 14 on the limit bracket 13. According to the principle of threaded transmission, the rotation angle of the threaded rod 20 is proportional to the extension length of the hexagonal support rod 19. Therefore, the threaded rod 20 can be adjusted by adjusting the rotation angle of the threaded rod 20. The extended length of the hexagonal support rod 19 can be obtained by converting the rotation angle, and the extended length of the hexagonal support rod 19 can be directly read out through the distance pointer 24 and the distance scale 23, that is, the height of the position of the hexagonal support rod 19 that needs to be adjusted. The above operation is simple and practical, and the structure is reasonable and compact. During the measurement process, the measuring base plate 12 is always in contact with the surface of the beam, and the measuring base plate 12 is connected to the internal sliding of the measuring device body 10 through the limit bracket 13 to improve the structural stability between the two, improve the stability of the device itself during the measurement process, so as to avoid the device from tilting during the measurement process to affect the accuracy of the measurement result, and improve the practicality of the device; in the initial state, the two limit brackets 13 form a downward pulling force on the two rotating shafts 15 through the reset spring 16 and the limit slip ring 17, so that the measuring device body 10 and the measuring base plate 12 can maintain a close contact, so as to avoid the relative sliding between the measuring device body 10 and the measuring base plate 12 when the device is not in use, which accelerates the damage of the device, and improves the practicality of the device.
