[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] Reference Figure 1-Figure 2 As shown, Figure 1 This is an exploded view of a wire-laying device specifically used for an inclined structure shown in the utility model; Figure 2 This is an overall diagram of a wire-laying device specifically for use with an inclined structure as shown in the utility model. Figure 1 and Figure 2 As shown, the utility model provides a wire-laying device specially used for an inclined structure, comprising: a base 1; a base 2, a lower part 23 of which is movably connected to the base 1, and a first laser projector 221 and a first battery 222 are arranged in the base 2; a rotating body 3, which is rotatably connected to the upper part 21 of the base 2, and a second laser projector 31 and a second battery 32 are arranged in the rotating body 3;

[0037] Among them, the base 2 is provided with a dial 4 on the end face of the rotating body 3, the first laser projector 221 is used to emit a reference laser line, and the second laser projector 31 is used to emit a measuring laser line. When the rotating body 3 rotates to the target position, the measuring laser line is used to calibrate the center line of the inclined structure, and measure the inclination angle of the inclined structure through the dial 4.

[0038] Specifically, the pay-off device mainly includes a base 1, a base 2 and a rotating body 3. Figure 3The schematic diagram of the structure of the base is shown. The base 1 is a basic part used to support and connect other parts, and its bottom is flat. The flat bottom structure ensures that the entire base 1 can be placed firmly on a plane without shaking or tilting. The movable connection of the base 2 relative to the base 1 allows the base 2 to rotate arbitrarily in space. The user can adjust the base 1 in the horizontal direction according to actual needs to ensure that it is in an ideal horizontal state, thereby providing a basis for subsequent horizontal layout.

[0039] In some embodiments, the base 1 is composed of two mounting components 11, and the two mounting components 11 can be assembled or separated from each other to facilitate installation and disassembly. In a more specific embodiment, the base 1 is provided with a circular groove and the bottom surface is flat, and the lower part 23 of the base 2 fits with the circular groove. The two mounting components 11 of the base 1 can be removably assembled to form the circular groove. Specifically, the cylindrical base 1 can be cut from the middle part to form two symmetrical mounting components 11, and the upper and middle parts 21 of each mounting component 11 are hollowed out to form a semi-circular groove. When the two mounting components 11 are relatively installed, the two semi-circular grooves form a circular groove, and the lower part 23 of the base 2 is inserted into the circular groove, so that the base 2 can be arbitrarily adjusted in the space inside the base 1 until the base 2 is in a horizontal position.

[0040] In some embodiments, a plurality of positioning pins 8 are provided at the bottom area of ​​one mounting component 11, i.e., the area staggered from the semicircular groove, and a plurality of positioning grooves 81 are provided at the corresponding position of the other mounting component 11. The two mounting components 11 are aligned and installed through the one-to-one correspondence between the positioning pins 8 and the positioning grooves 81.

[0041] Please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 The overall structure of the substrate and the cross-sectional structure from a frontal perspective are respectively shown. The substrate 2 can be divided into three parts: upper, middle and lower. The lower part 23 is spherical and can be embedded in the circular groove. Therefore, the part where the substrate 2 cooperates with the base 1 is a spherical clearance fit, and the spherical fitting surface can achieve omnidirectional adjustment, so that the substrate 2 can be freely adjusted in all directions in the space inside the base 1.

[0042] In some embodiments, one of the mounting components 11 is provided with a fastening hole 71. When the base 2 is adjusted to a horizontal position, the base 2 is locked by passing the fastener 7 through the fastening hole 71. The fastener 7 may be a knob, the head of which is a rotatable handle, and the tail of which is a rod with threads. The threaded rod may pass through the threaded fastening hole 71 of the mounting component 11 of the base 1 and tightly abut against the surface of the lower portion 23 of the base 2. Exemplarily, when the knob is rotated clockwise, the threaded rod will move forward and gradually approach the base 2, thereby fixing the base 2 on the base 1 to prevent it from moving or loosening. When the knob is rotated counterclockwise, the threaded rod retreats backward and gradually moves away from the base 2, thereby releasing the base 2 and readjusting its position.

[0043] In some embodiments, it is possible to determine whether the base 2 is adjusted to the required horizontal position by observing whether the bubble level 5 on the top of the base 2 is at the highest point in the center. In the bubble level 5, when the bubble is at the highest point in the center of the pipeline, the entire device can be considered to be horizontal. When the base 2 is not horizontal, the bubble level 5 on the base 2 will also tilt, causing the bubble to deviate from the center position. Therefore, by observing the position of the bubble in the pipeline, it is possible to determine whether the base 2 is horizontal and the accuracy of the horizontality.

[0044] Preferably, the bubble level 5 has a sensitivity of 0.01 mm / m, so that it can detect a smaller inclination angle and improve the measurement accuracy of the inclined structure.

[0045] The end surface of the base 2 is provided with a dial 4 to indicate the laying-out angle of the rotating body 3. In some embodiments, the upper portion 21 of the base 2 is a horizontally placed hollow cylinder, and the rotating body 3 is a cylinder with an outer diameter that is almost equal to the inner diameter of the upper portion 21 of the base 2, and the rotating body 3 is sleeved in the hollow area. The front end surface of the cylindrical shape of the base 2 is provided with the dial 4. The dial 4 can be a circular dial 4, which has the same path as the front end surface of the cylindrical base 2, and its scale range can be 0 to 360°. Among them, the scale at the right of the horizontal center of the dial can be set to 0°.

[0046] The difference between the outer diameter of the rotating body 3 and the inner diameter of the upper portion 21 of the base body 2 is preferably about 0.05 mm.

[0047] The base 2 has a built-in first battery 222 and a first laser projector 221. When the base 2 is in a horizontal position, the laser line emitted by the first laser projector 221 can be used as a reference laser line. The first battery 222 is a rechargeable lithium-based battery that can be charged and discharged multiple times within the service life of the device to provide reliable power support for the first laser projector 221. Within the service life of the device, the user can charge it repeatedly and ensure that it can be used for a long time.

[0048] like Figure 6 As shown, Figure 6 The second battery 32 and the second laser projector 31 are in the rotating body 3, wherein the first laser projector 221 and the second laser projector 31 have the same principle and structure, and the first battery 222 and the second battery 32 have the same principle and structure.

[0049] The difference is that since the rotating body 3 can rotate in the upper part 21 of the base 2, the position of the laser line emitted by the second laser projector 31 can be changed by adjusting the position of the rotating body 3 until the green light emitted by the second laser projector 31 is at the target position. When the rotating body 3 is at the target position, the laser line emitted by the second laser projector 31 can be used as a measuring laser line. At this time, the angle between the measuring laser line and the reference laser line is the inclination angle of the inclined structure, which can be directly read on the dial 4. At the same time, the position where the measuring laser line is projected on the inclined structure is the center line of the inclined structure.

[0050] Among them, in the embodiment of the utility model, the inclined structure can generally refer to a component in a building or structure that has a certain angle relative to the vertical or horizontal direction. These inclined structures may be intentionally designed or may be generated during the construction, installation or use process. The user can change the line-laying angle by adjusting the position of the rotating body 3 on the vertical plane, and the ray with the required angle position can be obtained, which is the center line of the required inclined structure.

[0051] The use process of the utility model is as follows: fix the device at a suitable position so that it is in a roughly horizontal state, and by adjusting the relative position of the base 2 and the base 1, when the bubble in the bubble level 5 on the top of the base 2 is at the center highest point, the entire device is horizontal, and the base 2 is tightened by the knob; turn on the switch of the first laser projector 221 in the base 2, and the green light emitted by the projector is the horizontal reference line; turn on the switch of the second laser projector 31 in the rotating body 3, and the green light emitted by the projector is projected onto the corresponding component, and the angle calibrated by the dial 4 is the angle between the component and the horizontal position, and then by adjusting the position of the rotating body 3 on the vertical plane, the ray of the required angle can be obtained, that is, the center line of the required inclined structure is determined.

[0052] Thus, the device provides a more intuitive and accurate method of laying out the line. The angle of the inclined structure can be directly measured by the cooperation of the scale plate 4 and the laser projector without the need for additional calculations. By adjusting the position of the rotating body 3 until the measuring laser line is at the target position, the center line of the inclined structure can be determined without converting it into a horizontal distance or a vertical distance, which simplifies the measurement process and calculation steps and improves the efficiency and accuracy of the measurement.

[0053] In a further technical solution, the base 2 is further provided with a first charging port 223 of a lithium-based power source and a first touch switch 224 of a laser projector; the rotating body 3 is further provided with a second charging port 33 of a lithium-based power source and a second touch switch 34 of a laser projector. The first charging port 223 and the second charging port 33 can be used to connect charging devices, and users can charge the first battery 222 / second battery 32 inside the base 2 / rotating body 3 through the charging port. The first laser projector 221, the first touch switch 224 and the first charging port 223 are located in the middle part 22 of the base 2, and are staggered with the upper part 21 of the base 2 where the rotating body 3 is installed and the lower part 23 of the connecting base 1. Users can easily trigger the first laser projector 221 to smoothly emit a reference laser line, and it is convenient for users to insert the charging cable for charging at any time during use without disassembling the line release device. The second charging port 33 and the second laser projector 31 are respectively located at the front and rear ends of the rotating body 3, and are staggered from the externally mounted base 2. The user can easily trigger the second laser projector 31 to smoothly emit a measuring laser line, and the user can easily insert the charging cable for charging at any time during use without disassembling the line-releasing device.

[0054] In some embodiments, projection windows are provided at corresponding positions of the base 2 and the rotating body 3 , and the projection windows may be flush with or slightly raised from the outer surface of the base 2 / rotating body 3 so that the laser can pass through.

[0055] In some embodiments, an indicator mark can be set on the end face of the rotating body 3 close to the dial 4. The indicator mark is flush with the dial 4 and can rotate relative to the center of the end face of the rotating body 3. When the measuring laser line is at the target position, the pointer direction of the indicator mark can be moved to coincide with the direction of the measuring laser line. Therefore, after turning off the laser projector, the inclination angle of the inclined structure can be obtained by reading the position angle of the indicator mark.

[0056] It should be explained that the corresponding lithium-based batteries and projectors inside the base 2 and the rotating body 3 can be controlled separately. The width of the green light emitted by the projector is about 1 mm. The rotating body 3 can be fixed at any position, and the device accuracy is determined by the manufacturing accuracy, with a maximum error of 0.5°.

[0057] In this embodiment, the first touch switch 224 is turned on to control the first laser projector 221 to emit a reference laser line, which extends along the bottom surface of the inclined structure; the second touch switch 34 is turned on to make the measuring laser line emitted from the end surface of the rotating body 3 and projected onto the inclined structure. By rotating the rotating body 3, the laying angle of the measuring laser line is changed to the target position. At this time, the angle calibration on the dial 4 is observed to measure the inclination of the inclined structure. The measuring laser line at the target position is used as the center line of the inclined structure for subsequent work to ensure that the entire structure is in the desired position.

[0058] In a further technical solution, at least one wedge block 6 is provided in the hollow cylindrical shape of the upper part 21 of the base 2, and the rotating body 3 is installed in the hollow structure of the base 2 and fixed by the wedge block 6. Specifically, the inner surface of the hollow structure of the base 2 is provided with a plurality of wedge-shaped grooves 61, and the plurality of wedge blocks 6 are in interference fit with the base 2, and the wedge blocks 6 are tightly fixed in the wedge-shaped grooves 61 in the base 2. Among them, the bottom surface of the wedge block 6 is in interference fit with the base 2, and the top surface is in interference fit with the rotating body 3, and the top surface of the wedge block 6 is at a distance from the inner surface of the base 2, that is, the wedge block 6 protrudes from the base 2 and has a distance from the base 2, and the face-to-face contact between the rotating body 3 and the base 2 is changed to the face-to-face contact between the rotating body 3 and the wedge block 6, thereby reducing the contact area between the two, and facilitating the manual adjustment of the rotating body 3 to any position in the vertical plane.

[0059] The distance of the protruding portion of the wedge block 6, that is, the portion not embedded in the base 2, can be selected according to actual conditions, and the embodiment of the utility model is not limited to this.

[0060] In some embodiments, the wedge block 6 may have different shapes, including strip, wedge, rectangle, etc. Preferably, a strip-shaped wedge block 6 is provided along the length direction of the base 2 to facilitate integration with the base 2 and the rotating body 3 .

[0061] In some embodiments, the length of the wedge 6 can be the same as or different from the length of the rotating body 3. For example, the length of the wedge 6 can be equal to the length of the rotating body 3, which is convenient for installation. The length of the wedge 6 can also be shorter than the length of the rotating body 3 to save materials. In some embodiments, three wedges 6 are arranged at equal angles along the circumferential direction of the base 2. By evenly distributing the three wedges 6 at intervals, balanced support can be provided in different directions, improving the stability and balance between the base 2 and the rotating body 3, making the rotation process of the rotating body 3 smoother, while avoiding increasing the weight and complexity of the device, and reducing the difficulty of installation and disassembly.

[0062] In a further technical solution, a plurality of dot-shaped protrusions are arranged on the surface of each wedge block 6 in contact with the rotating body 3. In this embodiment, the rotating body 3 is inserted into the hollow structure of the base 2, and the rotating body 3 is fixed by the dot-shaped protrusions on the top surface of the wedge block 6. The contact surface between the dot-shaped protrusions and the rotating body 3 is small, and the face-to-face block contact between the rotating body 3 and the wedge block 6 is changed to the face-to-face point contact between the rotating body 3 and the dot-shaped protrusions, further reducing the contact area between the two. Compared with the full contact, the contact area of ​​the point contact is smaller, so that the rotation is more convenient.

[0063] In some embodiments, the dot-shaped protrusions may be cylindrical protrusions, conical protrusions, spherical protrusions, star-shaped protrusions, polygonal protrusions, prismatic protrusions or other geometric shapes or a combination thereof. In some embodiments, the wedge block 6 may not need to protrude from the inner surface of the base 2, and the dot-shaped protrusions may be provided on the wedge block 6 flush with the inner surface of the base 2. The height of the dot-shaped protrusions determines the gap between the base 2 and the rotating body 3, and the height of the dot-shaped protrusions may be selected according to different requirements, which is not limited in the embodiments of the utility model.

[0064] As a further explanation of this embodiment, the above-mentioned base 2 and rotating body 3 are respectively hollow structures, with a fixed bracket arranged inside to fix the lithium-based battery and the laser projector, and then a curing agent is used to fill the remaining space. In this embodiment, the curing agent, as a material for filling and curing the space, can increase the rigidity and strength of the structure, and can also prevent the deformation or rupture of the structure, as well as prevent dust and moisture from invading the interior of the structure, which helps to maintain the normal operation of the internal components. In this embodiment, the curing agent can be selected from epoxy curing agent, polyurethane curing agent, silicone rubber curing agent, etc., which are widely available and easy to cure and form.

[0065] In summary, the utility model provides a special laying-out device for inclined structures, including a bubble level 5, a rotating body 3, a wedge 6, a base 2 and a base 1; the base 1 and the base 2 are in a clearance fit, and the base 2 can be adjusted arbitrarily in the space inside the base 1 until the base 2 is in a horizontal position, and then the base 2 is pressed by the knob on the left. The bubble level 5 is assembled with the base 2 to check whether the device is in a horizontal state. The wedge 6 and the base 2 are in an interference fit, and the wedge 6 is tightly fixed in the wedge-shaped groove 61 in the base 2; the rotating body 3 is inserted into the hollow structure of the base 2, and the rotating body 3 is fixed by the dot-shaped protrusions on the top surface of the wedge 6. The dot-shaped protrusions have a small contact surface with the rotating body 3, and the rotating body 3 can be manually adjusted to any position in the vertical plane. In this way, the utility model can easily project rays in any space, which is used to lay out inclined components in engineering, or to check the angle of existing components. It has the characteristics of simple structure, convenient operation, high precision, and wide application range.
