[0038] like Figures 1 to 11 As shown, a construction measurement standardized fixed spraying device includes a spraying frame 1. In this embodiment, the size of the spraying frame 1 can be selected in the following range: the horizontal length is 500mm-600mm, the vertical width is 250mm-300mm, such as Figure 3 As shown, a placement groove 101 is provided on one side of the spray frame 1. Figure 1 As shown, a spray plate 2 is placed inside the placement groove 101, and a marking hole 201 is opened on the side wall of the spray plate 2. Two horizontally arranged adjustment and fixing components are placed on the side of the spray frame 1 away from the spray plate 2. The adjustment and fixing components are used to fix the spray frame 1 and the spray plate 2 on the frame column, and the two adjustment and fixing components are respectively located on the top and bottom sides of the spray frame 1;

[0039] like Figure 6 As shown, the adjustment and fixing assembly includes a limit slide tube 3 arranged on one side of the spray frame 1, and both ends of the limit slide tube 3 are slidably installed with limit inner slide rods 4, and one end of the limit inner slide rod 4 located outside the limit slide tube 3 is fixedly installed with a limit claw 5, as shown in FIG. Figure 7 , Figure 8 As shown, a hook spring 6 is arranged inside the limiting slide tube 3, and the hook spring 6 is located between the two limiting inner slide bars 4. A hanging ring 7 is fixedly installed at one end of the limiting inner slide bar 4 located inside the limiting slide tube 3, and the two hanging rings 7 are respectively hung on the two ends of the hook spring 6. In this embodiment, the size of the hook spring 6 can be selected: the outer diameter is 20mm, the wire diameter is 2.0mm, the length is 200mm, and the maximum stretching length is 400mm, so as to match the size of the spray frame 1, such as Figure 6 As shown, a positioning plate 8 is fixedly installed on one side of the limiting slide tube 3 close to the spray frame 1, and a plurality of positioning rods 801 are fixedly installed on the side wall of the positioning plate 8. Figure 2As shown in the figure, a plurality of positioning slots 102 adapted to the positioning insertion rods 801 are provided on the side wall of the spraying board 2. Specifically, when the standardized fixed spraying device for construction surveying is in use, first place the spraying board 2 inside the placement groove 101, make the spraying frame 1 fit with the spraying board 2, and then place the two groups of adjusting and fixing components on the top and bottom of the back of the spraying frame 1 in sequence, so that the positioning insertion rods 801 on the two positioning plates 8 are respectively inserted into a plurality of positioning slots 102 on the spraying frame 1, and the adjusting and fixing components are combined with the spraying frame 1 together. Then pull the limiting claws 5 on both sides, so that the hooked springs 6 inside the two limiting inner sliding rods 4 and the limiting sliding tubes 3 slide and stretch. After that, press the spraying frame 1 and the spraying board 2 tightly against the frame column, and release the limiting claws 5 so that the two limiting claws 5 are stuck on both sides of the frame column under the elastic force of the hooked springs 6, locking the spraying frame 1 and the spraying board 2 at the specified height on the frame column. Finally, spray paint towards the identification holes 201 on the spraying board 2, and then remove the spraying frame 1 and the spraying board 2 to complete the spraying of the identification. This construction surveying standardization can change the size of the adjusting and fixing components according to the size of the frame column, is applicable to frame columns with a size of 600 mm - 1000 mm, solves the spraying problems of most projects, and at the same time is convenient and efficient in operation, enabling the work that originally required two people to be completed by one person, greatly improving work efficiency, reducing working time, and at the same time liberating the hands of workers during spraying, avoiding paint staining hands and clothes.

[0040] As Figure 2 , Figure 5 shown, threaded frames 9 are fixedly installed on both the top and bottom of the spraying frame 1, and horizontally arranged hand-tightening bolts 10 are screwed on the threaded frames 9. One end of each hand-tightening bolt 10 is fixedly installed with a first sector plate 11. As Figure 4 shown, two first sector grooves 202 adapted to the first sector plates 11 are provided on the side of the spraying board 2 facing away from the spraying frame 1, and the two first sector grooves 202 are distributed on one side of the top and bottom of the spraying board 2. Specifically, by setting the hand-tightening bolts 10, after the spraying board 2 is placed in the placement groove 101, the upper and lower hand-tightening bolts 10 can be rotated in sequence, so that the two first sector plates 11 are respectively rotated into the two first sector grooves 202 on the upper and lower parts of the spraying board 2. At the same time, the hand-tightening bolts 10 drive the first sector plates 11 to generate displacement and press tightly on one side of the spraying board 2, so that the first sector plates 11, the spraying board 2, and the spraying frame 1 are on the same plane, locking the spraying board 2 inside the placement groove 101 and quickly fixing the spraying board 2.

[0041] As Figure 5 shown, second sector plates 12 are fixedly sleeved on the hand-tightening bolts 10. As Figure 6As shown, on the sides of the two positioning plates 8 facing away from each other, second sector grooves 802 adapted to the second sector plates 12 are provided; specifically, by providing the second sector plates 12, after the spraying plate 2 and the adjusting and fixing assembly are respectively assembled on both sides of the spraying frame 1, the hand-tightening bolt 10 is rotated to lock the spraying plate 2 inside the placement groove 101. At the same time, the rotating hand-tightening bolt 10 drives the second sector plates 12 to respectively snap into the second sector grooves 802 on the two positioning plates 8. When locking the adjusting and fixing assembly, the upper adjusting and fixing assembly can be locked first. After the first adjusting and fixing assembly assembles the spraying frame 1 on the frame column, then the lower adjusting and fixing assembly is installed, and the two adjusting and fixing assemblies are sequentially locked on the spraying frame 1 to complete the synchronous locking of the spraying plate 2 and the adjusting and fixing assembly, with simple and fast operation.

[0042] As Figure 6 shown, on the sides of the limiting slide tubes 3 facing away from the spraying frame 1, horizontally arranged control slide tubes 13 are fixedly installed. As Figure 9 shown, inside both ends of the control slide tubes 13, linkage slide rods 14 are slidably installed. At the ends of the linkage slide rods 14 located outside the control slide tubes 13, control claws 15 are fixedly installed. The four control claws 15 are respectively fixedly installed on the four limiting claws 5. As Figure 10 shown, inside the control slide tubes 13, a linkage gear 16 is rotatably installed. The linkage gear 16 is located between the two linkage slide rods 14. Inside the control slide tubes 13, two linkage toothed rods 17 symmetrically distributed about the axis position of the linkage gear 16 are slidably installed. At the ends of the two linkage toothed rods 17 away from each other, control rods 18 are fixedly installed. One ends of the two control rods 18 are respectively fixedly connected to one ends of the two linkage slide rods 14; specifically, by providing the control slide tubes 13 and the linkage slide rods 14, when the worker pulls one of the linkage slide rods 14 on one side of the adjusting and fixing assembly, it will drive the linkage gear 16 to rotate through the control rod 18 and the linkage toothed rod 17, and then drive the other group of linkage toothed rods 17 and control rods 18 to slide in the opposite direction, so that the two linkage slide rods 14 slide synchronously, and then drive the two limiting inner slide rods 4 to slide and stretch synchronously through the control claws 15 and the limiting claws 5, enabling the worker to operate with one hand and further reducing the operation difficulty.

[0043] As Figure 8 shown, inside the limiting slide tubes 3, a placement rack 21 is fixedly installed. On the top of the placement rack 21, a spring tube 22 is snap-fitted. The hooked spring 6 is located inside the spring tube 22. As Figure 6As shown, a maintenance hole is provided at the top of the limit sliding tube 3. A spring cover plate 19 is placed inside the maintenance hole. Two fastening sliders 20 are slidably installed at the top of the limit sliding tube 3, and the fastening sliders 20 are distributed on both sides of the top of the spring cover plate 19. Specifically, by providing the spring tube 22, the spring tube 22 is sleeved outside the hooked spring 6, which can shape the hooked spring 6, prevent the middle part of the spring from sagging when it is in the stretched length and is not conducive to fixation. At the same time, after multiple operations, if the hooked spring 6 has the problem of weak retraction, the fastening slider 20 can be slid and the spring cover plate 19 can be opened, and the spring tube 22 can be removed to replace the hooked spring 6, thereby extending the service life of the spraying device.

[0044] As Figure 2 shown, a first suspension bracket 23 is fixedly installed at the bottom of the spraying frame 1. A horizontally arranged suspension rod 24 is rotatably installed on the first suspension bracket 23. As Figure 1 、 Figure 11 shown, a second suspension bracket 25 is rotatably sleeved on the suspension rod 24. A height-fixing box 26 is fixedly installed at the bottom of the second suspension bracket 25. A winding box 27 is fixedly installed inside the height-fixing box 26. A tape measure 28 is wound inside the winding box 27. In this embodiment, the winding box 27 and the tape measure 28 are common coil spring reset type tape measures on the market. An observation window 2601 corresponding to the position of the tape measure 28 is provided on the side wall of the height-fixing box 26. Specifically, by providing the tape measure 28, after the spraying frame 1 is installed on the frame column, the height-fixing box 26 will deflect slightly around the suspension rod 24 under the action of gravity, so that the height-fixing box 26 always remains in a vertical state, acting as a plumb bob. At this time, the tape measure 28 inside the height-fixing box 26 can be pulled and observed through the observation window 2601 to fix the height of the spraying frame 1. By providing the cross scissor frame 33, the control knob 31 on the rotatable side can be rotated.

[0045] As Figure 11As shown in the figure, a horizontally arranged double-headed screw rod 29 is rotatably installed inside the height-fixed box 26. Travel nuts 30 are screwed onto both ends of the double-headed screw rod 29. One end of the double-headed screw rod 29 extends to the outside of the height-fixed box 26 and is fixedly installed with a control knob 31. A horizontally arranged limit slide rail 32 is fixedly installed on the top inner wall of the height-fixed box 26. Both travel nuts 30 are slidably installed at the bottom of the limit slide rail 32. The same cross-shaped scissors frame 33 is rotatably installed at the bottom of the two travel nuts 30. Sliding sleeves 34 are rotatably installed at both bottom ends of the cross-shaped scissors frame 33. The same positioning slide rod 35 is slidably installed inside the two sliding sleeves 34. The bottom end of the tape measure 28 is fixedly sleeved with a positioning frame 36. The positioning frame 36 is fixedly connected to the positioning slide rod 35. Specifically, the double-headed screw rod 29 and the travel nuts 30 drive the cross-shaped scissors frame 33 to deform and stretch downward, and then drive the tape measure 28 to automatically stretch through the sliding sleeves 34, the positioning slide rod 35 and the positioning frame 36, simplifying the operation steps during height fixing. At the same time, after height fixing, the cross-shaped scissors frame 33 can play a supporting role.

[0046] As Figure 11 shown, a protective bottom plate 37 is fixedly installed at the bottom of the positioning frame 36. The protective bottom plate 37 is located at the bottom of the height-fixed box 26 and is adapted to the height-fixed box 26. Specifically, by setting the protective bottom plate 37, after the spraying is completed, when the cross-shaped scissors frame 33 contracts into the height-fixed box 26, it will drive the protective bottom plate 37 below to be buckled at the bottom of the height-fixed box 26, closing the height-fixed box 26, playing a role in protection, moisture-proof and dust-proof, prolonging the service life of the double-headed screw rod 29, and facilitating the later maintenance of the double-headed screw rod 29.

[0047] As Figure 11 shown, vertically arranged positioning telescopic rods 38 are fixedly installed on both sides of the top of the protective bottom plate 37. The top ends of the two positioning telescopic rods 38 are fixedly connected to the inner wall of the height-fixed box 26. Specifically, by setting the positioning telescopic rods 38, when the cross-shaped scissors frame 33 drives the protective bottom plate 37 to move up and down, the positioning telescopic rods 38 on both sides of the top of the protective bottom plate 37 can play a positioning role for the protective bottom plate 37, preventing the protective bottom plate 37 from shaking left and right. At the same time, the bottom end of the tape measure 28 is positioned through the positioning slide rod 35 and the positioning frame 36, preventing the tape measure 28 from being skewed.

[0048] In summary: When the standardized fixed spraying device for construction surveying is in use, first place the spraying plate 2 inside the placement groove 101, make the spraying frame 1 fit with the spraying plate 2, then place the two sets of adjusting and fixing components on the top and bottom of the back of the spraying frame 1 in sequence, so that the positioning insertion rods 801 on the two positioning plates 8 are respectively inserted into the multiple positioning slots 102 on the spraying frame 1, and the adjusting and fixing components are combined with the spraying frame 1. Then pull the limiting claws 5 on both sides, so that the hooked springs 6 inside the two limiting inner sliding rods 4 and the limiting sliding tubes 3 slide and stretch. After that, press the spraying frame 1 and the spraying plate 2 tightly against the frame column, and release the limiting claws 5 so that the two limiting claws 5 are stuck on both sides of the frame column under the elastic force of the hooked springs 6, locking the spraying frame 1 and the spraying plate 2 at the specified height on the frame column. Finally, spray paint towards the marking holes 201 on the spraying plate 2. After that, remove the spraying frame 1 and the spraying plate 2 to complete the spraying of the marking. This construction surveying standardization can change the size of the adjusting and fixing components according to the size of the frame column, and is applicable to frame columns with a size of 600mm - 1000mm, solving the spraying problems of most projects. At the same time, the operation is convenient and efficient, enabling the work that originally required two people to be completed by one person, greatly improving the work efficiency, reducing the working time, and liberating the hands of workers during spraying, avoiding paint from staining hands and clothes. By setting the hand-tightening bolts 10, after the spraying plate 2 is placed in the placement groove 101, the upper and lower hand-tightening bolts 10 can be rotated in sequence, so that the two first sector plates 11 are respectively rotated into the two first sector grooves 202 on the upper and lower sides of the spraying plate 2. At the same time, the hand-tightening bolts 10 drive the first sector plates 11 to generate displacement and press against one side of the spraying plate 2, making the first sector plates 11, the spraying plate 2, and the spraying frame 1 on the same plane, locking the spraying plate 2 inside the placement groove 101 and quickly fixing the spraying plate 2. By setting the second sector plates 12, after the spraying plate 2 and the adjusting and fixing components are respectively assembled on both sides of the spraying frame 1, rotate the hand-tightening bolts 10 to lock the spraying plate 2 inside the placement groove 101. At the same time, the rotating hand-tightening bolts 10 drive the second sector plates 12 to respectively snap into the second sector grooves 802 on the two positioning plates 8. When locking the adjusting and fixing components, the upper adjusting and fixing component can be locked first. After the first adjusting and fixing component assembles the spraying frame 1 on the frame column, then install the lower adjusting and fixing component, and lock the two adjusting and fixing components on the spraying frame 1 in sequence to complete the synchronous locking of the spraying plate 2 and the adjusting and fixing components. The operation is simple and fast. By setting the control sliding tube 13 and the linkage sliding rod 14, when the worker pulls the linkage sliding rod 14 on one side of the adjusting and fixing component, it will drive the linkage gear 16 to rotate through the control rod 18 and the linkage rack 17, and then drive the other set of linkage rack 17 and the control rod 18 to slide in the opposite direction, so that the two linkage sliding rods 14 slide synchronously. Furthermore, through the control claws 15 and the limiting claws 5, the two limiting inner sliding rods 4 are driven to slide and stretch synchronously, enabling the worker to operate with one hand and further reducing the operation difficulty. By setting the spring tube 22,The spring tube 22 is sleeved outside the hooked spring 6, which can shape the hooked spring 6 and prevent the middle part from sagging when the spring is in the stretched length, which is not conducive to fixing. At the same time, after multiple operations, if the hooked spring 6 has the problem of weak retraction, the sliding fastening slider 20 can be slid and the spring cover plate 19 can be opened, and the spring tube 22 can be removed to replace the hooked spring 6, extending the service life of the spraying device. By setting the tape measure 28, after the spraying frame 1 is installed on the frame column, the height-fixing box 26 will deflect slightly around the suspension rod 24 under the action of gravity, so that the height-fixing box 26 always maintains a vertical state and plays the role of a plumb bob. At this time, the tape measure 28 inside the height-fixing box 26 can be pulled, and the spraying frame 1 can be fixed in height by observing through the observation window 2601. By setting the cross scissor frame 33, when the control knob 31 on the rotatable side is rotated, the cross scissor frame 33 can be deformed and stretched downward through the double-headed screw rod 29 and the traveling nut 30, and then the tape measure 28 can be automatically stretched through the sliding sleeve 34, the positioning slide rod 35 and the positioning frame 36, simplifying the operation steps when fixing the height. At the same time, after the height is fixed, the cross scissor frame 33 can play a supporting role. By setting the protective bottom plate 37, after the spraying is completed, when the cross scissor frame 33 contracts into the height-fixing box 26, it will drive the lower protective bottom plate 37 to be buckled at the bottom of the height-fixing box 26 to close the height-fixing box 26, playing the role of protection, moisture-proof and dust-proof, extending the service life of the double-headed screw rod 29 and facilitating the later maintenance of the double-headed screw rod 29. By setting the positioning telescopic rod 38, when the cross scissor frame 33 drives the protective bottom plate 37 to move up and down, the positioning telescopic rods 38 on both sides of the top of the protective bottom plate 37 can play a positioning role for the protective bottom plate 37 to prevent the protective bottom plate 37 from shaking left and right. At the same time, the bottom end of the tape measure 28 is positioned by the positioning slide rod 35 and the positioning frame 36 to prevent the tape measure 28 from skewing.,
