[0016] Based on the same inventive concept, the present invention discloses a method for using a clean room measuring point device, comprising the following steps:

[0017] When the clean room measuring point device is needed to measure the point, first install the measuring point device body on the bracket base, and open the bracket body in the bracket base to allow the measuring point device body to perform the measuring point operation;

[0018] When the card is in the lower card slot, the rope is in a relaxed state, and the reset spring drives and flips the rotating rod and the fixed frame to reset, so that the fixed frame and the rolling ball flip down and fit the ground; when the card is in the upper card slot, the rope pulls the rotating rod and the fixed frame to rotate, and the rolling ball is retracted.

[0019] When the measuring point equipment body needs to be moved, push the clamp to the side close to the slider, compress the positioning spring, push the slider and move it to the lower short slot, release the clamp, insert the clamp into the lower short slot, the rope body is in a relaxed state, and the reset spring drives and flips the rotating rod and the fixing frame to reset, so that the fixing frame and the rolling ball flip down and fit the ground, driving the clean room measuring point device to move;

[0020] When long-term stable placement is required, the card is pushed toward the side close to the slider, the positioning spring is compressed, the card is moved out of the lower short slot, the slider is pushed upward, the slider cooperates with the rope body to drive the rotating rod and the fixing frame to rotate, the reset spring is stressed, and the rolling ball is retracted. When the slider moves to the upper short slot, the card is released, the positioning spring drives the card to reset, and the card is clamped into the upper clamping slot to limit the fixing frame and the rolling ball.

[0021] When the bracket body needs to be parked for a short time, the positioning screw is rotated, the positioning screw is pulled out from the positioning hole on the surface of the moving rod, the moving rod is slid in the hollow sleeve, the moving rod drives the stabilizing plate to fit with the ground, and the positioning screw is rotated, and the positioning screw is inserted into the positioning hole on the surface of the moving rod;

[0022] When the bracket body needs to be stored, the bracket body is rotated into the storage groove on the surface of the stable disk, and then the fixed screw rod and the rotating disk are pushed to rotate, and the rotating disk drives the abutment rod to rotate, and the abutment rod intercepts and restricts the bracket body, and the threaded cap is rotated so that the threaded cap and the pressure pad abut against the surface of the stable disk;

[0023] When the measuring point equipment body needs to be calibrated to be horizontal, first determine whether the measuring point equipment body is in a horizontal position by using a level meter. When the measuring point equipment body is not horizontal, rotate the adjusting knob to drive the gear to rotate, and drive the first rack and the second rack to move oppositely through the gear to adjust the overall length of the bracket body. After adjusting to the required position, rotate the fixing knob to limit the rotation of the gear in cooperation with the threaded rod, thereby limiting the relative movement of the first rack and the second rack.

[0024] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages:

[0025] (1) When the device needs to be moved, the present invention uses an adjustment device to unfold the ball to fit the ground, and uses the ball to drive the device to move as a whole. When the device needs to be placed stably for a long time, the adjustment device can fold the ball. This can effectively reduce the need for frequent equipment handling when the existing clean room measurement point device is at the measurement point, reduce the workload of personnel, reduce the work intensity of personnel, thereby improving the efficiency of clean room measurement points, and at the same time improve the overall practicality of the device;

[0026] (2) When the bracket body needs to be parked for a short period of time, the stabilizing plate of the stabilizing assembly generates friction with the ground, thereby improving the stabilizing effect of the equipment when it is parked and placed;

[0027] (3) When the bracket body needs to be stored, the present invention sets a storage device to rotate the bracket body into the storage groove on the surface of the stabilizing disk. The fixed screw and the rotating disk are pushed to rotate, and the rotating disk drives the push rod to rotate. The push rod intercepts and restricts the bracket body. Then, the threaded cap is rotated to make the threaded cap and the pressure pad abut against the surface of the stabilizing disk. The push rod can restrain the bracket body in the storage groove on the surface of the stabilizing disk, so that the equipment can be stored, thereby reducing the need to use ropes to tie the bracket of the existing measuring point device when storing it, which causes troublesome operation.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, providing these embodiments will make the disclosure thorough and complete and fully convey the scope of the present invention to those skilled in the art. In the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity. The same reference numerals throughout represent the same components.

[0041] like Figure 1 to Figure 4As shown, the present invention discloses a clean room measuring point device, including a bracket base 1, a bracket body 2, a measuring point equipment body 3, an adjustment component 4, a stabilization component 5, a storage component 6, an extension component 7, a level 70 and a fixing box 79. The lower surface of the bracket base 1 is rotatably connected with three bracket bodies 2, a measuring point equipment body 3 is arranged above the bracket base 1, and an adjusting device 4 is arranged on the surface of the bracket body 2. The adjusting device 4 includes a fixed frame 41, a rolling ball 42, a slot 43, a slider 44, a fixed rod 45, a positioning spring 46, a clamp 47, a rope body 48, a rotating rod 49, a reset spring 410, a take-up drum 411, an auxiliary rod 412 and a positioning slot 413, wherein the rotating rod 49 is rotatably connected to the inner wall of the bracket body 2, the surface of the rotating rod 49 is fixedly connected with the fixed frame 41, the inner wall of the fixed frame 41 is provided with a rolling ball 42, the surface of the rotating rod 49 is fixedly connected with the take-up drum 411, a sliding hole is opened on the surface of the bracket body 2, and the inner wall of the sliding hole in the bracket body 2 is slidably connected with a slider 44, and a side surface of the slider 44 is fixedly connected with a rope body 48, and one end of the rope body 48 is fixed and wound with the take-up drum 411. When the bracket body 2 provided by the present invention is in use, the rotating rod 49 on the bracket body 2 cooperates with the two fixed frames 41 and the ball 42 to facilitate the movement of the equipment, thereby reducing the need to constantly move the equipment in the clean room during the measurement process, which causes inconvenience in operation. At the same time, the slider 44 and the rope body 48 are pushed, and the rope body 48 drives the rotating rod 49 and the fixed frame 41 to rotate, thereby retracting the ball 42, making it convenient to align the equipment with the required measurement point position and facilitate the completion of the measurement operation.

[0042] like Figure 3 As shown, two fixing rods 45 are fixedly connected to both sides of the slider 44, and the surfaces of the two fixing rods 45 are slidably connected with clamps 47. Two clamping grooves 43 are provided on the surface of the bracket body 2, and the clamps 47 are clamped with the inner walls of the clamping grooves 43. When the clamping grooves 43 provided by the present invention are used, the clamping grooves 43 are set in a U shape, and are composed of an upper short groove, a lower short groove and a long groove. The clamps 47 are against the inner wall of the lower short groove or the upper short groove. The clamps 47 cooperate with the clamping grooves 43 on the surface of the bracket body 2 to limit the slider 44 and improve the overall stability. When the slider 44 needs to be moved, the two clamps 47 are first squeezed toward the middle so that it is no longer restricted by the clamping grooves 43, and then the slider 44 can be slid. When the clamp 47 is located in the lower short groove, the rope body is in a relaxed state, and the reset spring 410 drives and flips the rotating rod 49 and the fixing frame 41 to reset, so that the fixing frame 41 and the rolling ball 42 flip downward and fit the ground; when the clamp 47 is located in the upper short groove, the rope body 48 pulls the rotating rod 49 and the fixing frame 41 to rotate, and the rolling ball is retracted.

[0043] like Figure 3 As shown, a positioning spring 46 is sleeved on the surface of the fixing rod 45 , and two ends of the positioning spring 46 are fixedly connected to the surfaces of the slider 44 and the clamp 47 respectively.

[0044] When the positioning spring 46 provided by the present invention is in use, the positioning spring 46 can control the reset of the card member 47, so that the card member 47 can be stably inserted into the card slot 43 to improve the stability effect. When the slider 44 moves from one end of the card slot 43 to the other end, the card member 47 will cooperate and restrict with the card slot 43 again under the action of the positioning spring 46, thereby limiting the position of the slider 44.

[0045] like Figure 4 and Figure 5 As shown, two reset springs 410 are sleeved on the surface of the rotating rod 49, and the two ends of the two reset springs 410 are fixedly connected to the inner wall of the sliding hole on the surface of the winding drum and the bracket body 2 respectively. The reset spring 410 is a torsion spring. When the angle between the fixed frame 41 and the bracket body 2 changes, the reset spring can provide elastic potential energy by deformation. Furthermore, when the fixed frame 41 is not subjected to force, it can be reset by the elastic potential energy of the reset spring 410, that is, the initial angle between the fixed frame 42 and the bracket body 2 is maintained; the function of the reset spring is to drive the fixed frame and the ball to rotate and reset. When the reset spring 410 provided by the present invention is in use, when the fixed frame 41 and the ball 42 need to return to their original positions, the reaction force of the reset spring 410 can drive and flip the rotating rod 49 and the fixed frame 41 to reset, so that the fixed frame 41 and the ball 42 flip downward and fit the ground. At the same time, under the action of the reset spring 410, the stability of the fixed frame 41 and the ball 42 during operation can be improved. As shown Figure 4 As shown, an auxiliary rod 412 is fixedly connected to the surface of the fixing frame 41, and a positioning groove 413 is provided on the surface of the bracket body 2, and the auxiliary rod 412 is plugged into the positioning groove 413. When the auxiliary rod 412 provided by the present invention is in use, after the reset spring 410 drives the fixing frame 41 and the rolling ball 42 to unfold, the auxiliary rod 412 will be inserted into the positioning groove 413 on the surface of the bracket body 2. Under the action of the auxiliary rod 412, the fixing frame 41 and the rolling ball 42 can be limited to prevent them from deflecting or shifting, and it also has a positioning function.

[0046] like Figure 1 and Figure 6As shown, a stabilizing component 5 is provided on the lower surface of the bracket base 1. The stabilizing component 5 includes a hollow sleeve 51, a stabilizing disk 52, a moving rod 53, a positioning screw 54 and a positioning hole 55. The hollow sleeve 51 is fixedly connected to the lower surface of the bracket base 1. The moving rod 53 is slidably connected to the inner wall of the hollow sleeve 51. One end of the moving rod 53 is fixedly connected to the stabilizing disk 52. The inner wall of the hollow sleeve 51 is threadedly connected to the positioning screw 54. A positioning hole 55 is provided on the surface of the moving rod 53. The positioning screw 54 is plugged into the inner wall of the positioning hole 55. When the stabilizing component 5 provided by the present invention is in use, the moving rod 53 can drive the stabilizing disk 52 to move in the hollow sleeve 51. The stabilizing disk 52 fits the ground to improve stability. The positioning screw 54 is rotated to insert the positioning screw 54 into the positioning hole 55 on the surface of the moving rod 53 for positioning. The length of the moving rod 53 can be adjusted according to different usage scenarios and can be flexibly adjusted. Figure 7 As shown, the positioning hole 55 includes an upper positioning hole 551 and a lower positioning hole 552, and the positioning screw 54 is respectively plugged into the inner wall of the upper positioning hole 551 and the lower positioning hole 552. When the positioning screw 54 provided by the present invention is in use, when the positioning screw 54 cooperates with the upper positioning hole 551 or the lower positioning hole 552, the moving rod 53 can be limited at different positions, thereby increasing the adjustment range of the moving rod 53.

[0047] like Figure 6 to Figure 8 As shown, the stabilizing disk 52 is a hollow disk body, an arc groove is provided on the upper surface of the stabilizing disk 52, a receiving groove corresponding to the bracket body is provided on the side of the stabilizing disk 52, and a receiving assembly 6 is provided on the inner wall of the stabilizing disk 52, and the receiving assembly 6 includes a rotating disk 61, a push rod 62, a fixed screw 63, a threaded cap 64 and a pressure pad 65. The rotating disk 61 is rotatably connected to the inner wall of the stabilizing disk 52, three push rods 62 are fixedly connected to the surface of the rotating disk 61, and a fixed screw 63 is fixedly connected to the surface of the rotating disk 61. The arc groove on the stabilizing disk 52 is for the fixed screw 63 to pass through, the surface of the fixed screw 63 is threadedly connected to the threaded cap 64, and the lower surface of the threaded cap 64 is fixedly connected to the pressure pad 65. When the storage assembly 6 provided by the present invention is in use, the bracket body 2 is rotated into the storage groove on the surface of the stabilizing disk 52, and the fixing screw 63 and the rotating disk 61 are pushed to rotate, so that the fixing screw 63 moves along the arc groove, and the rotating disk 61 drives the push rod 62 to rotate, and the push rod 62 intercepts and restricts the bracket body 2, and then the threaded cap 64 is rotated to make the threaded cap 64 abut against the surface of the stabilizing disk 52, thereby limiting the relative movement of the rotating disk 61, and the pressure pad 65 increases the friction between the threaded cap 64 and the stabilizing disk 52, which can reduce the loosening and self-rotation of the threaded cap 64.

[0048] A fixing box 79 is fixedly connected to the front side of the support base 1, and two level gauges 70 are fixedly connected to the front side of the fixing box 79. Fig. 9 and Fig.10As shown, an extension assembly is provided on the upper part of the bracket body 2, and the extension assembly includes a fixed knob 71, a mounting frame 72, a connecting rod 73, a threaded rod 74, a gear 75, a first rack 76, an adjusting knob 77 and a second rack 78. The first rack 76 is penetrated and slidably connected to the inner side of the mounting frame 72, and a second rack 78 is provided on the other side of the first rack 76, and the second rack 78 penetrates and is slidably connected to the mounting frame 72. A gear 75 is penetrated and rotatably connected to the middle part of the inner side of the mounting frame 72, and the gear 75 is respectively connected to the first rack 76 and the second rack 78 are meshingly connected, an adjusting knob 77 passes through the outside of the mounting frame 72 and is rotatably connected, and the adjusting knob 77 passes through and is fixedly connected to the gear 75, a threaded rod 74 is fixedly connected to the rear side of the gear 75, and a fixing knob 71 is threadedly passed through the outer ring of the threaded rod 74 and is threadedly connected, a connecting rod 73 passes through and is slidably connected to the top of the first rack 76 and the bottom of the second rack 78, and the other ends of the connecting rod 73 are fixedly connected to the bracket body 2, wherein the connecting rod 73 can increase the supporting force of the extension component during the movement of the first rack 76 and the second rack 78.

[0049] When the extension assembly provided by the present invention is used, firstly, the fixing box 79 and the level 70 are used to determine whether the measuring point device body 3 is in a horizontal position. When the two level 70 are observed to know that the measuring point device body 3 is not horizontal, the adjusting knob 77 is rotated to drive the gear 75 to rotate, and the gear 75 drives the first rack 76 and the second rack 78 to move in opposite directions, thereby adjusting the overall length of the bracket body 2. After adjusting to a suitable position, the fixing knob 71 is further rotated, and the relative movement of the gear 75 is limited in cooperation with the threaded rod 74, and the relative movement of the first rack 76 and the second rack 78 is limited at the same time, wherein the connecting rod 73 can increase the supporting force of the extension assembly during the movement of the first rack 76 and the second rack 78. In the present invention, the fixing knob 71 is fixed to the mounting frame 72 by the cooperation of the threaded rod 74. When the fixing knob 71 is restricted and fixed, the gear 75 cannot rotate either. When the gear 75 cannot rotate, the external force cannot act to make the first rack 76 and the second rack 78 move in opposite directions.

[0050] The present invention provides a method for using a clean room measuring point device, comprising the following steps:

[0051] When the clean room measuring point device is required to perform measuring points, the measuring point device body 3 is first installed on the bracket base 1, and the bracket body 2 is opened in the bracket base 1, so that the measuring point device body 3 can perform measuring point operations.

[0052] When the measuring point device body needs to be moved, the clamp 47 is pushed toward the side close to the slider 44, the positioning spring 46 is compressed, the slider 44 is pushed and moved to the lower short groove, the clamp 47 is released, the clamp 47 is inserted into the lower short groove, the rope 48 is in a relaxed state, and the reset spring 410 drives and flips the rotating rod 49 and the fixing frame 41 to reset, so that the fixing frame 41 and the rolling ball 42 are flipped downward and fit the ground, driving the clean room measuring point device to move;

[0053] When long-term stable placement is required, the clamp 47 is pushed toward the side close to the slider 44, the positioning spring 46 is stressed, the positioning spring 46 is compressed, the clamp 47 moves out of the lower short groove in the slot 43 on the surface of the bracket body 2, loses its restraint, pushes the slider 44, the slider 44 cooperates with the pull rope to drive the rotating rod 49 and the fixing frame 41 to rotate, the reset spring 410 is stressed, so that the ball 42 is retracted, and when the slider 44 moves to the short groove on the release position, the clamp 47 is released, the positioning spring 46 drives the clamp 47 to reset, and the clamp 4 7 is inserted into the inner wall of the card slot 43 to limit the fixing frame 41 and the ball 42. By setting the adjustment component 4, it is convenient to adjust the bracket in the clean room measuring point device and move it conveniently, avoiding the need for the existing clean room measuring point device to frequently change positions when measuring points, and manually lift the measuring point device to the next position. When measuring points in multiple places, frequent handling of equipment will increase the manual workload, reduce the work intensity of workers, improve the measurement efficiency of the clean room measuring points, and at the same time improve the overall practicality of the equipment.

[0054] When the bracket body 2 needs to be parked for a short time, by setting up the stabilizing component 5, the positioning screw 54 can be rotated, and the positioning screw 54 can be pulled out from the lower positioning hole 552 on the surface of the moving rod 53, and the moving rod 53 is slid in the hollow sleeve 51. The moving rod 53 drives the stabilizing plate 52 to fit the ground. At this time, the positioning screw 54 is rotated and inserted into the upper positioning hole 551 on the surface of the moving rod 53, so that the stabilizing plate 52 generates friction with the ground, thereby improving the stability of the equipment when it is parked and placed.

[0055] When the bracket body 2 needs to be stored, the storage device 6 is set up to rotate the bracket body 2 into the storage groove on the surface of the stabilizing disk 52, and then the fixing screw 63 and the rotating disk 61 are pushed to rotate. The rotating disk 61 drives the push rod 62 to rotate, and the push rod 62 intercepts and restricts the bracket body 2. Then, the threaded cap 64 is rotated to make the threaded cap 64 and the pressure pad 65 resist the surface of the stabilizing disk 52. The push rod 62 can restrain the bracket body 2 in the storage groove on the surface of the stabilizing disk 52, so that the equipment can be stored, reducing the need to use ropes to tie the existing measuring point device bracket when storing, which causes troublesome operation. The storage operation is simplified while improving the storage efficiency.

[0056] When it is necessary to calibrate the measuring point equipment body 3 to be horizontal, first determine whether the measuring point equipment body 3 is in a horizontal position through the fixing box 79 and the level 70. When it is found that the measuring point equipment body 3 is not horizontal by observing the two level gauges 70, the gear 75 is driven to rotate by rotating the adjusting knob 77, and the first rack 76 and the second rack 78 are driven to move by the gear 75, thereby adjusting the overall length of the bracket body 2. When it is adjusted to a suitable position, the fixing knob 71 is further rotated, and the relative movement of the gear 75 is limited in cooperation with the threaded rod 74, and the relative movement of the first rack 76 and the second rack 78 is limited at the same time.
