Description

Technical Field

[0001] The present invention relates to the technical field of laser rulers, and particularly to an adsorption type horizontal positioning laser ruler and an application method thereof. Background Art

[0002] Wall drilling positioning is widely used in daily applications, such as installing wall-mounted TV brackets, installing photo drilling positions, installing cabinets, wall cabinets, etc. Previously, traditional methods used straight rulers for measurement and manual visual observation to determine whether it was centered and level. However, this traditional positioning technology has large errors on the one hand, and on the other hand, the process is very complex and sometimes cannot be completed by a single person. Therefore, laser ray locators have emerged on the market. Currently, more commonly used in this technology are support type positioning devices. Such devices require tripods or support rods to adjust the height and then emit light for distance measurement and positioning, which is very troublesome. And limited by the height of the tripod or support rod, high positions or narrow spaces will also cause difficulties in operation. There are also some products that have developed adsorption devices, but they can only achieve adsorption on glass or ceramic tile walls and cannot adsorb on rough walls. Moreover, these products can currently only achieve the function of ray assistance and cannot achieve distance measurement and precise midpoint finding, or precise finding of multiple related hole positions. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an adsorption type horizontal positioning laser ruler and an application method thereof to solve the technical problems mentioned in the background art.

[0013] Specifically, the adsorption column, the middle valve column, and the adsorption seat are all conical bodies. A leak-proof valve is also sleeved outside the air valve. The leak-proof valve has a plurality of inverted anti-leakage valve flaps, and the outer edge of the anti-leakage valve flap abuts against the inner wall of the outer adsorption cavity.

[0014] Specifically, a rotation module is further included. The rotation module can help the laser ruler module perform a rotation action relative to the adsorption module.

Then deflate the adsorption component through the air release component, and then move this device to reach this midpoint position. When moving, you can first position this device to meet one of N or M, and then meet the other through secondary movement, so as to obtain a punching point position for centering and fixing the height of the entire wall surface; or start the laser ruler module, cooperate with the rotation module to measure the distance of the wall surface up, down, left and right, obtain the height of the wall surface as h, the width as L, calculate the distance between the midpoint of the wall surface and the axis point of this device as A through the Pythagorean theorem, take an external folding angle auxiliary device to reach the predetermined midpoint position, and at the same time rotate the laser ruler module until the reading shown on the display screen of the laser ruler module is A, and at this time, this is the midpoint position of the positioning point on the wall surface.

Detailed implementation manners

[0045] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination can be formed among the following-described embodiments or technical features to form a new embodiment.

[0046] Reference Figures 1 to 18 :

[0047] The present invention patent discloses an adsorption type horizontal positioning laser ruler, including: an installation base 10, an installation cavity is formed by depression inside the installation base 10. Specifically, the installation base 10 is a housing component. A basic linear module 20 is provided inside the installation base 10, and the basic linear module 20 can emit at least one guiding light ray. Preferably, two mutually perpendicular guiding light rays are emitted, and normally one light ray is horizontal and one is upward or downward vertical guiding light ray; the guiding light ray can emit light rays of different colors or the same color through the selection of the laser head. In addition, multiple laser heads can be customarily switched on and off through system control. It further includes an adsorption module 30, and the adsorption module 30 is installed at the lower end of the installation base 10 and can adsorb the installation base 10 on the wall surface manually or automatically; it also includes a calibration module 40, and the calibration module 40 is installed on the installation base 10 and can check whether the installation base 10 is in a horizontal state together with the basic linear module 20; it further includes a laser ruler module 50, and the laser ruler module 50 is installed at the upper end of the installation base 10 or integrated on the installation base 10 and can measure the distance to the target object. Specifically, the laser ruler is a prior art and can be added or integrated on the installation base 10. Preferably, the light ray emitted by the laser ruler module 50 is parallel to one of the light rays emitted by the basic linear module 20. With such a setting, when this laser ruler is placed on the wall surface, start the basic linear module 20 and cooperate with the calibration module 40 to determine whether this device is horizontal. If it is not horizontal, then rotate this device. When it is confirmed to be horizontal, start the adsorption module 30 and help the adsorption module 30 adsorb this device on the wall surface manually or electrically. Then, use the light ray emitted by the laser ruler module 50 to measure the distance from the position of the wall surface where this device is located to one side. Of course, in individual cases, the laser ruler can be a two-way laser ruler or a three-way or four-way laser ruler. If it is a two-way laser ruler or a three-way or four-way laser ruler, the distances from the wall surface where this device is located to both sides of the wall, as well as the distances to the wall top and the ground can be measured simultaneously, so as to know the length and width of the entire wall surface. Thus, the distance and height from the midpoint of the wall surface to the wall edge can be calculated through calculation. Then, move this device over and re-measure twice or four times. That is, measure once every time you move one step. If it corresponds to the initial data, the position where this device is located is the midpoint position of the wall surface. Of course, in individual cases, although the position to be installed is at the horizontal midpoint, it is not at the vertical midpoint. For example, when installing a photo frame or drilling holes for installing a TV stand, at this time, a rough height needs to be visually positioned, and then the horizontal midpoint is positioned at this height position. During the installation of the TV stand, usually two or four holes need to be drilled. When two holes need to be drilled, after selecting the midpoint, then calculate and measure the positions of the two side holes through the laser ruler.

[0048] As shown in the figure is the embodiment of calculating the midpoint in the above embodiment. Refer to Figures 12 - 13, this device is first positioned at any position on the wall, and the wall length is measured to be equal to L1 + L2, and the wall height is equal to H1 + H2. Then, the horizontal midpoint position is calculated as (L1 + L2) / 2, and the vertical midpoint position is calculated as (H1 + H2) / 2. Thus, by coordinating the movement of the external corner auxiliary device and the measurement of the laser ruler module 50, the specific positions of the horizontal midpoint and the vertical midpoint can be calculated. For example, if the installation position requires horizontal centering but not vertical centering, then after displacing in the vertical direction as needed, check again whether it is horizontally centered. By operating like this, only by attaching this device to any point on the wall can it be completed. Compared with the traditional device that can only emit rays and cannot accurately measure distances, this device can complete centering positioning without the assistance of a measuring tool.

[0049] Reference Figure 4 、 Figures 16 to 18 , specifically, the basic straight line module 20 is a laser head. In the preferred embodiment of a dual laser head, the laser head includes a first laser head 201 and a second laser head 202, where the first laser head 201 and the second laser head 202 face perpendicular to each other. The laser line emitted by the laser ruler module 50 is parallel to the light emitted by the first laser head 201 or the second laser head 202. Thus, the colored ray emitted by the basic straight line module 20 can be used to locate the horizontal or vertical direction, and then in cooperation with the calibration module 40 of the spirit level, confirm whether it is in the vertical or horizontal direction. As other alternative embodiments, the number of laser heads is four, which are respectively located in the up, down, left, and right perpendicular directions. The guiding light rays emitted by these four lasers form a cross and can be customarily opened and closed by the system. In this way, when there are four guiding light rays, it can more quickly help this device define the horizontal and vertical directions. As other alternative embodiments, the number of laser heads is eight, which are respectively located in the up, down, left, right, upper left, lower left, upper right, and lower right eight directions. The light rays emitted by the eight laser heads form a cross shape, and the angle between the light rays emitted by each adjacent laser head is 45 degrees. These eight laser heads are customarily opened and closed by the system. The eight laser heads can help this device on a wall without column or ceiling obstruction by irradiating two or four diagonal corners of the wall with two or four of the diagonal lines among them, thereby helping this device more quickly determine the horizontal or vertical direction.

[0050] Specifically, a display device 50a is also integrated within the laser ruler module 50. The display device 50a is a display screen module. The data calculated by the combined action of the laser emission end and the receiving end of the laser ruler is sent to the control center in real time through the control center such as the chips and control boards built into the laser ruler module 50, and is displayed in real time through the display device 50a. At the same time, an input and confirmation module can be attached. When the external folding angle assistor reaches the positioning point 721 and the data measured by the laser ruler module 50 just matches the set data, the display gives a sound prompt or a light prompt to prompt the user to move into place. Specifically, the adsorption module 30 is a suction cup assembly, which includes a suction cup body 1, a vacuum pumping device 2, and an air release component 3. The suction cup body 1 is installed at the bottom of the installation base 10 and relies on the vacuum pumping device 2 to pump out the air, and the air can be released through the air release component 3. Among them, the vacuum pumping device 2, the suction cup body 1, and the air release component 3 are all connected through pipelines. The calibration module 40 is a spirit level. Here, the spirit level can be an electronic spirit level or a physical spirit level. A transparent cover is also provided on the installation base 10 to help check whether the bubble point of the spirit level is centered. In some alternative embodiments, the adsorption assembly can also be an adhesive, such as a sticker, which can complete the adsorption function by means of a replaceable adhesive sticker and manual auxiliary positioning.

[0051] Specifically, the suction cup main body 1 includes a housing silica gel pad 11 and a suction housing 12. One side of the suction housing is provided with an extension area 121. In some embodiments, there is an obvious thin material area at the edge of the extension area 121 and the suction housing 12, which facilitates the upward suction of the extension area 121. In some embodiments, the extension area 121 and the suction housing 12 are made of the same material, and the powerful vacuum pump 214 can suck the extension area 121 upward. In addition, the housing silica gel pad 11 can be fixed in a clamping manner with the bottom of the suction housing 12 through the elastic expansion of the bottom metal washer. The housing silica gel pad 11 has a flat end face to help it adhere to the wall, and at the same time, it adheres to the fine concave and convex parts of the wall by virtue of its soft nature. When a vacuum is formed inside the suction housing 12, the soft silica gel in its soft end face can fill the fine concave and convex parts, so as to achieve the maximum adsorption force. Specifically, an adsorption column 122 is provided inside the extension area 121. The middle frame 4 is connected to the inner side or the lower end of the mounting base 10. An adsorption seat 41 is provided on the middle frame 4. An outer adsorption cavity 401 is formed inside the adsorption seat 41. An air valve 5 is provided between the required outer adsorption cavity 401 and the adsorption column 122. An inner adsorption cavity 501 is formed inside the air valve 5. A ventilation pipe 123 is provided on one side of the outer adsorption cavity 401. A pressure sensor 124 is provided on one side of the ventilation pipe 123. The pressure sensor 124 is electrically connected to the control board and is responsible for transmitting the pressure value inside the outer adsorption cavity 401 to the main control board, and the main control board determines whether the device is in the best adsorption state. By setting a range value in advance for the system, such as the required vacuum pressure values for various walls such as glass walls, sticker walls, painted walls, and roughcast walls are different. After setting the pressure value in advance, the user can select the application scenario in the display screen. When the application scenario is selected, the adsorption module 30 can control the adsorption pressure under the control of the main control board through the adsorption time of the vacuum pump 214 and the continuously monitored pressure sensor 124. In addition, the vacuum pump 214 can be started in real time during the measurement process in this device for supplementary air extraction to prevent problems such as air leakage or a decrease in adsorption force after long-term adsorption, and to prevent the device from falling off the wall, which will cause losses. For example, when the user selects a certain application scenario, after the first adsorption is in place, the pressure value is detected at intervals. When the pressure value is lower than a certain value, the vacuum pump 214 is started once. The start time of the vacuum pump 214 also varies for different application scenarios. For example, the glass wall requires the least pressure, it is the easiest to adsorb and the least likely to leak air, so its detection interval time is the longest, and the start time of the vacuum pump 214 for the second and third times is the shortest, and so on. Specifically, the vacuum pumping device 2 includes a vacuum pump 214 and a three-way pipe 22. The air release component 3 is an exhaust solenoid valve 31. The three nozzles of the three-way pipe 22 are respectively communicated with the vacuum pump 214, the exhaust solenoid valve 31, and the ventilation pipe 123. The application of the exhaust solenoid valve 31 in the suction cup device is an original creation of this patent because the rotation problem in the rotation module 6 also needs to be considered.If traditional manual air release is adopted, the device structure will be very complex. After installing the exhaust solenoid valve 31, this problem can be perfectly solved, and full-automatic air release can also be achieved. When operating the air release on the display screen, the system reminds the operator to hold the device by hand to prevent it from falling after deflating. In addition, in order to consider the problem of the internal structure sealing of the vacuum pump 214, here, a check valve 301 is also provided between the three-way pipe 22 and the vacuum pump 214. The check valve 301 can prevent gas from flowing back through the vacuum pump 214, preventing air leakage due to its internal sealing when the vacuum pump 214 is not working, that is, gas can only flow out from the outer adsorption cavity 401 to the vacuum pump 214 and cannot flow back.,

[0052] Specifically, the air valve 5 is a silica gel body and belongs to a type of sealing valve. However, it remains in a falling state when in a deflated state or a non-vacuum state, that is, it does not move upward to seal the outer adsorption cavity 401. Only when in a vacuum state, when the pressure reaches a certain value, the air valve 5 is pushed upward by the adsorption column 122 and can be pushed against the top of the outer adsorption cavity 401 or block the ventilation pipe 123, so as to form a complete sealed body that is connected between the entire outer adsorption cavity 401 and the inner adsorption cavity 501, so that a vacuum state can be maintained for a certain period of time without external supplementary air extraction.,

[0053] Specifically, the air valve 5 includes a bottom valve body 51, a middle valve column 52, and a top valve ring 53. The bottom valve body 51 is disposed opposite to the extension area 121, the middle valve column 52 is disposed opposite to the adsorption column 122. An inner adsorption cavity 501 is formed inside the middle valve column 52, and a stop valve cavity 531 is formed inside the top valve ring 53. The stop valve cavity 531 communicates with the inner adsorption cavity 501 through a first adsorption hole 532. The upper end of the adsorption column 122 is provided with a second adsorption hole 125, and the second adsorption hole 125 communicates with the inner adsorption cavity 501. Here, in a preferred embodiment, the position of the second adsorption hole 125 is offset from that of the first adsorption hole 532, that is, they are not vertically connected. In this way, when the inner adsorption cavity 501 is in a vacuum state and the adsorption column 122 is pushed upward against the top of the middle valve column 52 of the air valve 5, the first adsorption hole 532 can be sealed first. Subsequently, the air valve 5 is adsorbed upward and pushed upward, and its top valve ring 53 at the top abuts against the top of the outer adsorption cavity 401 to form a secondary seal. At the same time, this top valve ring 53 has a cavity property, so the cavity of its silica gel material, that is, the stop valve cavity 531, will have a buffering property. When the air in the inner adsorption cavity 501 is continuously evacuated, the stop valve cavity 531 will gradually shrink as the silica gel at the upper end is continuously compressed, and finally completely fill the top of the entire outer adsorption cavity 401 and block the ventilation pipe 123. At this time, a secondary seal is formed in the adsorption module 30. Together with the one-way valve 301, it is a triple seal, which maximally ensures that the vacuum environment in the adsorption module 30 will not leak air easily. In addition, the pressure sensor 124 detects the pressure at intervals and starts the vacuum pump 214 to supplement the air extraction.

[0054] Specifically, the adsorption column 122, the middle valve column 52, and the adsorption seat 41 are all conical bodies. The upper end of the conical adsorption column 122 is smaller than the lower end, which makes it more convenient for its upper end to be pushed upward and inserted into the conical middle valve column 52. At the same time, the upper end of the middle valve column 52 is also smaller than the lower end, which is also convenient for it to be pushed upward into the conical adsorption seat 41. Specifically, in order to prevent air leakage between the outside of the air valve 5 and the inner cavity of the adsorption seat 41 inside the outer adsorption cavity 401, here, a leak-proof valve 54 is sleeved outside the conical air valve 5. The leak-proof valve 54 has a plurality of inverted anti-leakage valve flaps 541. The outer edge of the anti-leakage valve flap 541 abuts against the inner wall of the outer adsorption cavity 401. When the air valve 5 is pushed upward or pulled upward, the outward-opening leak-proof valve flaps directly abut against the inner wall of the adsorption seat 41 or the outer adsorption cavity 401, further locking to prevent air from leaking into the inner adsorption cavity 501 through the bottom or the top.

[0055] Specifically, for daily use, after selecting any position for positioning, the position can be measured by the laser ruler module 50. Then, move or rotate the device, and adjust it to the predetermined position with the help of an external angle folding assistor. After that, start the adsorption module 30 to fix the device on the wall. Or, first fix the device at any point, then rotate the rotation module 6 for distance measurement, and cooperate with the external angle folding assistor and multiple Pythagorean or straight-line calculations to locate to the predetermined position. Relatively speaking, the former will consume more manpower and material resources, while the latter will be more convenient. Therefore, in this embodiment, the latter method is provided for operation. Specifically, the device further includes a rotation module 6. The rotation module 6 can help the laser ruler module 50 make a rotational movement relative to the adsorption module 30. The rotation module 6 includes a rotating bearing 61. On the inner side of the bottom of the inner adsorption cavity 501, there is an outer ring step 611 for fixing the outer ring of the rotating bearing 61. On the outer side of the bottom of the air valve 5 and the upper outer side of the extension area 121, there are respectively an inner ring upper step 612 and an inner ring lower step 613 for fixing the inner ring of the rotating bearing 61. With such a setting, the adsorption silica gel pad and the adsorption housing 12 at the bottom of the adsorption module 30 and the air valve 5 are arranged on the inner ring of the rotating bearing 61, while the middle frame 4, the mounting base 10 fixedly connected to the upper end of the middle frame 4, the laser ruler module 50, and the basic straight-line module 20 are all arranged on the outer ring of the bearing. Thus, when rotating, the mounting base 10 can be held by hand alone for rotation, and at the same time, the laser ruler module 50 and the basic straight-line module 20 will also rotate accordingly. In this way, it can help the device measure and position the punching positions of non-horizontal straight-line positions, such as the positioning of multiple photo frame holes on the wall, or the punching positioning of the hole positions of a TV stand with a non-parallel relationship (trapezoid), such as Figure 14 One of the positioning punching methods for a trapezoidal TV stand shown. First, locate the midpoint position, and then input the distances between the two upper holes and the two lower holes of the TV stand and the length of the oblique angle calculated in advance into the device. Thus, the chip can automatically calculate the angle and length that the device needs to rotate on the wall through the Pythagorean theorem. With the help of the external angle folding assistor and the system's prompt to reach the designated position, multiple hole positions of this trapezoid can be located, which is very convenient.

[0056] Specifically, it further includes a rotation positioning module 7. Here, the positioning module 7 includes the positioning damping effect brought by the adsorption module 30 itself, that is, due to the vacuum state between the air valve 5 and the inner cavity of the adsorption seat 41, which is the outer adsorption cavity 401, the damping effect brought by the air valve 5 pressing tightly against the adsorption seat 41 upward, so that when the installation base 10 is rotated, the installation base 10 with damping will not rotate by itself. Secondly, it is the positioning in the physical structure. Specifically: The rotation positioning module 7 includes a positioning ring 71 and a positioning member 73. The positioning ring 71 is arranged at the upper outer side of the outer shell silicone pad 11, and the positioning member 73 is arranged at the lower outer side of the middle frame 4. A rotating ring 72 is provided on the positioning ring 71, and a plurality of positioning points 721 are provided on the rotating ring 72. The output end of the positioning member 73 can abut against the rotating ring 72 or the positioning points 721 when rotating with the middle frame 4. The positioning member 73 is a spring bead assembly. Here, the positioning points 721 can be set at common angles such as horizontal, vertical, 45-degree angle, 30-degree angle, etc., and sensors are provided at these positioning points 721. When the sensor senses that the spring bead falls into its specific positioning point 721, the system can display the angle of rotation of the laser ruler module 50 through the display, and at the same time, it will also emit a ticking sound to help the user know which gear the blogger has reached. At the same time, it can also be displayed through the rotation angle on the display screen. Thus, with the assistance of the rotation positioning module 7, after rotating to a specific angle, and then through an external folding angle assistor, the specific position can be quickly located.

[0057] In other alternative embodiments, a micro-motor and a gear ring are also installed in the rotation module 6 of the present invention. The gear ring is distributed along the outer periphery of the installation base 10. The output end of the micro-motor is meshed with the gear ring through a gear, so as to realize the rotation of the upper installation base 10 by controlling the rotation of the micro-motor, thereby controlling the rotation of the laser ruler module 50. In this way, by inputting parameters into the system and the parameters of the preset positioning holes, the system calculates the parameter information of the position of the device itself and the distance from the preset positioning holes, and automatically rotates. After rotating in place, it reminds the operator to perform positioning along a straight line through an external folding angle assistor. When reaching the position of the predetermined hole, the system issues a prompt, and then the operator can use a marker pen to mark the position of the preset target positioning hole. By analogy, the positions of all preset positioning holes can be calculated in the form of rotating a full circle. This method can meet the requirements of hanging photo frames on the wall, hanging cabinets, or various items with staggered hanging methods. Through the preset staggered hanging arrangement, the information of the positioning holes in the preset drawing in the computer can be realized on the wall.

[0058] The present invention also discloses a positioning method for a horizontal height-centering hole position, which includes applying the aforementioned laser ruler and includes the following positioning steps:

[0059] S1. Adsorb the device at any position on the wall through the adsorption module 30;

[0060] S2. Start the basic linear module 20 and, in conjunction with the calibration module 40, determine whether the device is level. If it is not level, manually adjust the device to be level.

[0061] S3. Start the laser ruler module 50 and, in cooperation with the rotation module 6, measure the distance to the top, bottom, left, and right of the wall. Obtain the height of the wall as h, the width as L, and calculate the distance from the midpoint position of the wall to one side edge of the wall as N and the distance from the midpoint position of the wall to the roof or bottom surface on one side of the wall as M. Then, deflate the adsorption component through the air release component, and then move the device to this midpoint position. When moving, the device can be positioned to meet one of N or M first, and then the other can be met through a second movement, thereby obtaining a drilling point that is centered and at a fixed height on the entire wall; or start the laser ruler module 50 and, in cooperation with the rotation module 6, measure the distance to the top, bottom, left, and right of the wall. Obtain the height of the wall as h, the width as L, and calculate the distance from the midpoint of the wall to the axis point of the device as A through the Pythagorean theorem. Take an external angled auxiliary device to reach the predetermined midpoint position, and at the same time rotate the laser ruler module 50 until the reading on the display screen of the laser ruler module 50 shows A. At this time, this positioning point 721 is the midpoint position of the wall.

[0062] The present invention also discloses a positioning method for positioning multiple hole positions on a wall, including applying the aforementioned laser ruler, and including the following positioning steps:

[0063] S1: Adsorb the device on any position on the wall through the adsorption module 30.

[0064] S2: Start the basic linear module 20 and, in conjunction with the calibration module 40, determine whether the device is level. If it is not level, manually adjust the device to be level.

[0065] S3: Start the laser ruler module 50 and, in cooperation with the rotation module 6, measure the distance to the top, bottom, left, and right of the wall. Obtain the height of the wall as h, the width as L, to obtain the length and width dimensions of the wall and the specific position of the wall where this laser ruler device is located. Then, for multiple hole positions a1, a2,..., aN with a fixed relationship, calculate their specific positions on the wall through one - time Pythagorean or two - time Pythagorean calculations. Finally, use an external right - angle auxiliary device to reach the specific hole position for distance measurement, rotate the laser ruler, and confirm the specific positions of multiple hole positions with a fixed relationship through one - time Pythagorean or two - time Pythagorean calculations.

[0066] In other alternative embodiments, the device is connected to a mobile phone or a computer via an app. The width, height, and midpoint data of the wall surface pre-measured by the device are fed back to the system. The system generates forms of photos, cabinets, or other items in a proportional form. An operator selects a target item on the wall surface background generated by the system and modifies the length and width parameters of the item, fitting it into the desired placement area. After clicking the confirmation button, the system transmits the parameters and proportional parameters within the background to the device. Between the position of the device and the position of the designated selected placement area, the angle by which the device needs to rotate and the length of the inclined plane are automatically calculated using the Pythagorean theorem (either a single Pythagorean calculation or a double Pythagorean calculation). The length of the inclined plane is confirmed manually by moving an external angle folding assistor and following the system's prompt to reach the designated position. Finally, multi-hole positioning is achieved.

[0067] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
