[0036] In this embodiment, if Figure 1 and Figure 2 As shown, a construction measurement reference line payout device includes a payout groove wheel 1 and a load-bearing bracket 2, an offset component 3 is installed on the load-bearing bracket 2, the offset component 3 is used to change the use position of the payout groove wheel 1 to pay out the building wall perpendicular to the ground, the offset component 3 includes a support frame 31, a rotating shaft 32 and a cross bar 33, the support frame 31 is connected to the rotating shaft 32 through a bearing, the outer periphery of the rotating shaft 32 is connected to the center hole of the payout groove wheel 1, the cross bar 33 is inserted into the through hole of the support frame 31, and a positioning pin 34 is provided in the support frame 31, the support frame 31 is connected to the cross bar 33 through the positioning pin 34, and both ends of the cross bar 33 are fixedly connected to the load-bearing bracket 2.

[0037] Therefore, when marking the wall perpendicular to the ground, the support frame 31 is rotated in the cross bar 33. After the support frame 31 and the wall are perpendicular, the positioning pin 34 is used to re-fix the cross bar 33 and the support frame 31. At this time, the two wire-laying groove wheels 1 are set parallel to the wall. The wire in the wire-laying groove wheel 1 is pulled, and the wire-laying groove wheel 1 drives the rotating shaft 32 to rotate in the support frame 31, thereby marking the wall perpendicular to the ground.

[0038] Specifically, a through hole that is compatible with the cross bar 33 is processed in the support frame 31, the outer wall of the positioning pin 34 is processed with a thread, and threaded holes that are compatible with the positioning pin 34 are distributed in the cross bar 33. Two wire-releasing groove wheels 1 are fixedly connected to the rotating shaft 32, and the number of wire-releasing groove wheels 1 used is selectively installed according to usage requirements.

[0039] In some embodiments, as Figure 2 As shown, a locking member 321 is provided on the rotating shaft 32, and the locking member 321 is used to limit the rotation of the rotating shaft 32. The locking member 321 includes a chuck 321a, a spring leaf 321b and a push pin 321c. The center hole of the chuck 321a is connected to the rotating shaft 32, one end of the spring leaf 321b is fixedly connected to the support frame 31, and the other end of the spring leaf 321b is against the slot of the chuck 321a.

Under normal conditions, the spring sheet 321b presses against the groove of the chuck 321a, thereby braking the rotating shaft 32. The outer wall of the ejector pin 321c is processed with threads. By rotating the ejector pin 321c, when the spring sheet 321b is reset, the ejector pin 321c and the support frame 31 first contact each other, and then the spring sheet 321b will not contact the chuck 321a, and the rotating shaft 32 can rotate at this time.

[0041] In some embodiments, as Figure 4 As shown, a conductor assembly 4 is mounted on the support frame 31. The conductor assembly 4 is used to constrain the outlet position of the pay-off groove wheel 1. The conductor assembly 4 includes a connector 41, a screw 42, a threaded sleeve 43, and a collar 44. The screw 42 is connected to the support frame 31 through the connector 41. The threaded sleeve 43 is internally threaded with the screw 42. The collar 44 is hinged to the threaded sleeve 43 through a pin.

[0042] Specifically, the screw 42 is used to install the threaded sleeve 43, and the pin on the collar 44 is rotatably connected to the threaded sleeve 43 through a bearing. The surface of the collar 44 is smooth and is used for wiring.

[0043] In some embodiments, as Figure 4 As shown, the connecting member 41 includes a support arm 411, a connecting plate 412 and a threaded pin 413. One end of the support arm 411 is fixedly connected to the support frame 31. The connecting plate 412 is hinged to the end of the support arm 411 away from the support frame 31 through a pin shaft. The threaded pin 413 is inserted into the support arm 411. The threaded pin 413 is used to limit the rotation of the connecting plate 412.

[0044] Specifically, there is an angle less than or equal to 30 degrees between the support arm 411 and the support frame 31 , the connecting plate 412 can rotate in the support arm 411 , and the threaded pin 413 is used to limit the rotation of the connecting plate 412 to fix the use position of the screw 42 .

[0045] In some embodiments, as Figure 4 As shown, a fixing cap 421 is disposed on the screw rod 42 , and the fixing cap 421 is connected to the screw rod 42 via an internal thread.

[0046] Specifically, two fixing caps 421 are provided and distributed at both ends of the screw rod 42 . The fixing caps 421 are used to separate the threaded sleeve 43 from the screw rod 42 .

[0047] In some embodiments, as Figure 5 As shown, the supporting bracket 2 includes two strip plates 21 and reinforcing ribs 22 . The top ends of the two strip plates 21 are connected to the cross bar 33 , and the two ends of the reinforcing ribs 22 are fixedly connected to the two strip plates 21 .

[0048] Two strip plates 21 are provided. The reinforcing ribs 22 are used to increase the connection strength between the two strip plates 21 . The reinforcing ribs 22 and the crossbars 33 are provided in parallel.

[0049] In some embodiments, as Figure 5 As shown, a storage shell 211 is inserted into the outer periphery of the strip plate 21, the slide groove of the storage shell 211 is adapted to the reinforcing rib 22, the bottom end of the storage shell 211 is fixedly connected to the base 212, and a bolt 213 is provided in the storage shell 211, and the storage shell 211 is connected to the strip plate 21 through the bolt 213.

[0050] It should be noted that the inner cavity in the storage shell 211 is adapted to the strip plate 21, and a weight-reducing groove is processed in the base 212. The base 212 supports the entire mechanism, and the bolts 213 are used to fix the position of the strip plate 21 in the storage shell 211. By changing the position of the strip plate 21 in the storage shell 211 to adjust the use height of the support frame 31, it is convenient to mark walls of different heights.

[0051] In some embodiments, as Figure 2 As shown, grooves matching the positioning pins 34 are evenly distributed on the outer circumference of the crossbar 33 , and the grooves are used to fix the offset angle of the support frame 31 on the crossbar 33 .

[0052] Specifically, the grooves distributed on the crossbar 33 are used to connect with the positioning pins 34 , and the positioning pins 34 are inserted into the grooves at different positions to fix the support frame 31 at different positions on the crossbar 33 .

[0053] In some embodiments, as Figure 3As shown, the spring sheet 321b is processed with a spherical protrusion that matches the clamping groove of the chuck 321a.

[0054] A spherical protrusion is processed on one end of the spring piece 321b away from the support frame 31, and the spherical protrusion is clamped into the clamping groove of the chuck 321a to brake the rotating shaft 32. In addition, other fixing structures can also be used to limit the rotation of the rotating shaft 32.

[0055] In some embodiments, as Figure 4 As shown, the threaded sleeves 43 are symmetrically distributed with respect to the screw 42 .

[0056] The number of threaded sleeves 43 used corresponds to the number of wire-paying groove wheels 1 , and the position of the wire outlet in the collar 44 can be changed by adjusting the position of the threaded sleeve 43 on the screw rod 42 .

[0057] The working principle of this application is described below with a preferred embodiment:

[0058] When marking the line on a wall perpendicular to the ground, the support frame 31 is rotated in the cross bar 33. After the support frame 31 and the wall are perpendicular, the cross bar 33 and the support frame 31 are re-fixed using the positioning pin 34. At this time, the two wire-laying groove wheels 1 are set parallel to the wall, and the spring piece 321b is lifted close to the end of the chuck 321a. Then the top pin 321c is rotated. After the threaded portion of the top pin 321c completely passes through the spring piece 321b, the external force on the spring piece 321b is removed. After the spring piece 321b is reset, it will not contact the chuck 321a. Then the wire in the wire-laying groove wheel 1 is pulled, and the wire-laying groove wheel 1 drives the rotating shaft 32 to rotate in the support frame 31, and the wire-laying groove wheel 1 drives the rotating shaft 32 to rotate in the support frame 31. Laying out the wire mark, when it is necessary to adjust the offset position of the wire, first rotate the connecting plate 412 in the support arm 411 to drive the screw 42 to change its position, use the threaded pin 413 to fix the position of the connecting plate 412 in the support arm 411, pass the wire through the ring 44, and then rotate the threaded sleeve 43 on the outer wall of the screw 42, so that the threaded sleeve 43 drives the ring 44 to move, thereby changing the output position of the wire, move the strip plate 21 upward in the storage shell 211, the strip plate 21 drives the reinforcing rib 22 to move in the slide groove of the storage shell 211, and use the bolt 213 to fix the position of the strip plate 21 in the storage shell 211 to adjust the distance between the support frame 31 and the ground.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
