[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0031] The following is for reference. Figures 1-5 The positioning device 100 according to an embodiment of this application is described. The positioning device 100 proposed in this application can be applied to, but is not limited to, the positioning and installation of purlins of photovoltaic brackets. This application describes the application of the positioning device 100 to the positioning and installation of purlins of photovoltaic brackets as an example.

[0032] like Figure 1 , Figure 2 and Figure 4As shown, the positioning device 100 according to an embodiment of this application includes: a device body 1, a sliding mechanism 2, a scale 3, and a locking member 4. The sliding mechanism 2 is disposed on the device body 1 and includes a pulley 21, which is rotatably disposed; the scale 3 is along a first direction (i.e., Figure 1 , 5 The X-direction shown is movable or retractable and is provided on the device body 1; the locking member 4 is provided on the device body 1 and can lock the scale 3.

[0033] The sliding mechanism 2 is located on the device body 1. Specifically, the end of the sliding mechanism 2 closest to the device body 1 is connected to the device body 1. The sliding mechanism 2 and the device body 1 can be fixedly connected. For example, the connection method between the sliding mechanism 2 and the device body 1 can be, but is not limited to, welding, snap-fit, bolting, etc. As some embodiments of this application, the sliding mechanism 2 and the device body 1 are connected by bolts. The sliding mechanism 2 includes a pulley 21, which is located on the sliding mechanism 2 and can rotate. The pulley 21 and other parts of the sliding mechanism 2, excluding the pulley 21, can be engaged with shaft holes. As some embodiments of this application, the pulley 21 has one of a pivot shaft or a pivot hole, and other parts of the sliding mechanism 2, excluding the pulley 21, have the other of a pivot shaft or a pivot hole. The pulley 21 is rotatably configured through the engagement of the pivot shaft and the pivot hole.

[0034] The positioning device 100 includes a scale 3, which is positioned along a first direction (i.e., Figure 1 , 5 The scale 3 is movably mounted on the device body 1 in the X direction (as shown), that is, the scale 3 is mounted on the device body 1, and, along the first direction (i.e., Figure 1 , 5 The scale 3 is movable (as shown in the X direction), and as some embodiments of this application, along the first direction (i.e. Figure 1 , 5 The scale 3 can slide relative to the device body 1 (in the X direction shown). It should be noted that the scale 3 is printed with graduations to facilitate adjustment of its position according to the actual required purlin spacing. As some embodiments of this application, when the actual required purlin spacing is long, the scale 3 can slide relative to the device body 1 along the first direction (i.e., the X direction shown). Figure 1 , 5 (In the X direction shown), the scale 3 moves away from the device body 1 to increase the positioning length of the positioning device 100.

[0035] Scale 3 along the first direction (i.e. Figure 1 , 5 The scale 3 is retractable and mounted on the device body 1 in the X direction (as shown), that is, the scale 3 is mounted on the device body 1, and, along the first direction (i.e., Figure 1 , 5(shown in the X direction), the scale 3 is retractable. As some embodiments of this application, the scale 3 can be constructed as a nested internal structure and an external structure, and the internal structure and the external structure can move relative to each other so that the scale 3 can be retractable. This arrangement can make the maximum extension length of the positioning device 100 longer and improve the applicability of the positioning device 100.

[0036] The positioning device 100 includes a locking member 4, which is disposed on the device body 1 and can lock the scale 3. As some embodiments of this application, the locking member 4 can be configured as a locking bolt, which is disposed on the device body 1. By rotating the locking bolt, pressure is applied to the scale 3 to lock it. Furthermore, by rotating the locking bolt away from the scale 3, the scale 3 can be unlocked. The locking member 4 can fix the scale 3, thereby fixing the scale 3 in a certain position according to actual needs.

[0037] It should be noted that the positioning device 100 of this application has a sliding mechanism 2 including a pulley 21, which is achieved by causing the pulley 21 to move along the main shaft 200 in a first direction (i.e., Figure 1 , 5 The X-direction shown can be rolled, thereby driving the positioning device 100 to move along the first direction (i.e., the X-direction shown) on the main shaft 200. Figure 1 , 5 The positioning device 100 moves along the X direction (as shown). The friction between the positioning device 100 and the main shaft 200 is rolling friction, which results in low frictional resistance. This facilitates the movement of the positioning device 100 on the main shaft 200, reduces the labor intensity of workers, saves labor costs, and extends the service life of the positioning device 100. Furthermore, by setting the position along the first direction (i.e., ... Figure 1 , 5 A movable or extendable scale 3 (shown in the X direction) allows for easy adjustment of its position according to the required purlin spacing, reducing purlin installation errors. Furthermore, a locking element 4 is provided to lock the scale 3 when it reaches the desired position. When installing purlins for the same photovoltaic bracket, locking the scale 3 facilitates the installation of multiple purlins, making operation convenient and ensuring consistent spacing between adjacent purlins, further reducing installation errors. When installing purlins for different photovoltaic brackets, the locking element 4 can be loosened, allowing for adjustment and locking of the scale 3 according to the required purlin spacing, thus adapting to different photovoltaic bracket purlin installation spacings and offering good versatility.

[0038] Therefore, by setting a sliding mechanism 2 with pulley 21, the positioning device 100 can move on the main shaft 200, which facilitates the adjustment of the position of the positioning device 100, reduces the difficulty of operation for workers, and has low friction, which helps to extend the service life of the positioning device 100. Furthermore, by setting a movable or extendable scale 3 along the first direction, the scale 3 can be adjusted according to the actual required purlin spacing, so that the overall length of the positioning device 100 matches the actual required purlin spacing, which makes it easier for workers to install purlins and reduces installation errors. In addition, by setting a locking member 4, the scale 3 can be fixed to reduce the risk of scale 3 moving around and improve the reliability of the positioning device 100.

[0039] In some embodiments of this application, such as Figure 4 As shown, the sliding mechanism 2 also includes a mounting component 22, which includes a mounting plate 221 and a mating plate 222. The mounting plate 221 is disposed on the device body 1, and the mating plates 222 are connected to both opposite ends of the mounting plate 221. The pulley 21 is located between the two mating plates 222 and is rotatably disposed on the two mating plates 222.

[0040] The mounting component 22 may include a mounting plate 221 and a mating plate 222. The mounting plate 221 (i.e., the end of the sliding mechanism 2 near the device body 1) is disposed on the device body 1. As some embodiments of this application, the mounting plate 221 and the device body 1 may be fixedly connected. For example, the connection method between the mounting plate 221 and the device body 1 may be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc.

[0041] Both ends of the mounting plate 221 are connected to mating plates 222. In some embodiments of this application, the plane of the mounting plate 221 is parallel to the moving plane of the positioning device 100, and the plane of the mating plate 222 is perpendicular to the moving plane of the positioning device 100. The two ends of the mounting plate 221 are respectively connected to the end of the corresponding mating plate 222 closest to the mounting plate 221. In other words, the two ends of the mounting plate 221 and the corresponding mating plate 222 are arranged in an L-shape. The connection method between the mounting plate 221 and the mating plate 222 can be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc., or the mounting plate 221 and the mating plate 222 can be integrally formed.

[0042] The pulley 21 is located between two mating plates 222 and is rotatably disposed on the two mating plates 222. The pulley 21 and the two mating plates 222 can be engaged with a shaft and a hole. As some embodiments of this application, the pulley 21 has one of a pivot shaft or a pivot hole, and each of the two mating plates 222 has the other of a pivot shaft or a pivot hole. The pulley 21 is rotatably disposed between the two mating plates 222 through the engagement of the pivot shaft and the pivot hole.

[0043] By providing a mounting component 22 including a mounting plate 221 and a mating plate 222, it is easy to install the sliding mechanism 2 onto the device body 1 and to install the pulley 21. The structure is simple and easy to assemble and disassemble. In addition, by rotatably positioning the pulley 21 between the two mating plates 222, the installation stability of the pulley 21 can be improved, and the risk of the pulley 21 tilting or falling off can be reduced.

[0044] In some embodiments of this application, such as Figures 1-4 As shown, the positioning device 100 further includes: a connector 5, the device body 1 having a first mounting hole 11, the mounting plate 221 having a second mounting hole 2211, and the connector 5 passing through the first mounting hole 11 and the second mounting hole 2211 to mount the mounting plate 221 on the device body 1.

[0045] The device body 1 has a first mounting hole 11, and the mounting plate 221 has a second mounting hole 2211. As some embodiments of this application, both the first mounting hole 11 and the second mounting hole 2211 can be constructed as through holes of the same shape and size. The first mounting hole 11 and the second mounting hole 2211 correspond to each other and are located along the thickness direction of the mounting plate 221 (i.e., along the thickness direction of the mounting plate 221). Figure 2 , 3 (As shown in the Z direction), the connector 5 is sequentially inserted through the first mounting hole 11 and the second mounting hole 2211 to mount the mounting plate 221 onto the device body 1. As some embodiments of this application, the connector 5 can be constructed as a bolt, along the thickness direction of the mounting plate 221 (i.e.,...). Figure 2 , 3 (As shown in the Z direction), bolts are sequentially inserted into the first mounting hole 11 and the second mounting hole 2211 and engaged with nuts to install the mounting plate 221 onto the device body 1.

[0046] As some embodiments of this application, a spring washer may be fitted onto one end of the connector 5 near the first mounting hole 11 to improve the tightness of the connection between the mounting plate 221 and the device body 1, thereby improving the stability of the positioning device 100 when it moves.

[0047] By setting the connector 5, the mounting plate 221 can be connected to the device body 1, which improves the tightness of the connection. In addition, the structure is simple and easy to disassemble and assemble the positioning device 100.

[0048] In some embodiments of this application, such as Figure 5 As shown, the scale 3 is along the first direction (i.e. Figure 1 , 5 The scale 3 (shown in the X direction) is movable and is located on the device body 1, and has a handle 31;

[0049] Alternatively, the scale 3 includes: a first scale section and a second scale section, the second scale section being along the first direction (i.e., Figure 1 ,5 The first ruler (shown in the X direction) is movably mounted on the first ruler portion, which is fixed to the device body 1 or along the first direction (i.e., Figure 1 , 5 The scale 3 is movable on the device body 1 in the X direction shown, so that the scale 3 is retractable on the device body 1, and the second scale part has a handle 31.

[0050] Among them, along the first direction (i.e. Figure 1 , 5 (shown in the X direction), a scale 3 is movably mounted on the device body 1, and the scale 3 has a handle 31. As some embodiments of this application, along the first direction (i.e. Figure 1 , 5 (As shown in the X direction), the handle 31 can be located at the end of the scale 3 that moves away from the device body 1. The scale 3 and the handle 31 can be fixedly connected. For example, the connection method between the scale 3 and the handle 31 can be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc., or the scale 3 and the handle 31 can be integrally formed.

[0051] As some embodiments of this application, along the width direction of the scale 3 (i.e. Figure 2 , 3 (as shown in Figure 5 in the Y direction), the handle 31 can be located on the side of the scale 3. As some embodiments of this application, such as... Figure 5 As shown, the handle 31 may include a connecting part and a toggle part, which are connected and have an included angle. In other words, the handle 31 may be constructed as an "L"-shaped rod. The connecting part may be connected to the scale 3, and the scale 3 may be adjusted by toggling the toggle part, thus facilitating the pulling of the scale 3. As some embodiments of this application, the handle 31 may be constructed as a rocker arm, and the scale 3 and the handle 31 may be connected by a hinge. When it is necessary to change the length of the scale 3, the handle 31 is unfolded away from the scale 3 for easy pulling. When the position of the scale 3 remains unchanged, the handle 31 is folded towards the scale 3 for easy storage and reduced space occupation.

[0052] As some embodiments of this application, the scale 3 may include: a first scale portion, a second scale portion, and along a first direction (i.e., Figure 1 , 5 (shown in the X direction), the second ruler is movably disposed on the first ruler. As some embodiments of this application, the first ruler and the second ruler can be slidably connected (e.g., through sliding engagement via a slide rail).

[0053] As some embodiments of this application, the first ruler portion is fixedly disposed on the device body 1. The first ruler portion and the second ruler portion can be constructed as a nested structure, with the first ruler portion sleeved on the second ruler portion, and the second ruler portion can be positioned along a first direction (i.e., ...). Figure 1 ,5 The first ruler moves in the X direction (as shown), and the first ruler is fixedly connected to the device body 1. For example, the connection between the first ruler and the device body 1 can be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc.

[0054] As some embodiments of this application, along the first direction (i.e. Figure 1 , 5 (shown in the X direction), the first ruler is movably disposed on the device body 1. As some embodiments of this application, the first ruler and the second ruler can be constructed as a nested structure, with the first ruler sleeved on the second ruler, and the second ruler movably disposed along the first direction (i.e., the X direction). Figure 1 , 5 The first ruler moves in the X direction (as shown), and the first ruler moves along the first direction (i.e., Figure 1 , 5 The first ruler (shown in the X direction) is movably disposed on the device body 1. For example, the connection between the first ruler and the device body 1 can be a sliding connection (e.g., sliding fit through a slide rail).

[0055] The second ruler has a handle 31, which makes it easy to pull the second ruler to change the length of the scale 3 according to the purlin spacing of different photovoltaic brackets.

[0056] It should be noted that the width direction of scale 3 (i.e. Figure 2 , 3 , the Y direction shown in 5), the first direction (i.e. Figure 1 , 5 The X direction shown), the thickness direction of the mounting plate 221 (i.e., the thickness direction of the mounting plate 221). Figure 2 , 3 Any two of the three directions (Z direction shown) are perpendicular to each other.

[0057] By providing a handle 31, it is easy to pull the scale 3 to change its length according to the purlin spacing of different photovoltaic brackets, which helps to improve the ease of use of the positioning device 100.

[0058] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, one of the device body 1 and the scale 3 has a mating groove 32, and the other of the device body 1 and the scale 3 has a mating protrusion 12. The mating protrusion 12 is guided and engaged with the mating groove 32, and the mating groove 32 is along the first direction (i.e. Figure 1 , 5 Extending in the X direction (as shown).

[0059] The device body 1 has a mating groove 32, and the scale 3 has a mating protrusion 12; alternatively, the scale 3 has a mating groove 32, and the device body 1 has a mating protrusion 12. The number of mating grooves 32 can be multiple, and the number of mating protrusions 12 is the same as the number of mating grooves 32 and corresponds one-to-one. In some embodiments of this application, both the number of mating grooves 32 and mating protrusions 12 are two, with the two mating grooves 32 extending along the width direction of the scale 3 (i.e.,...). Figure 2 , 3 The two mating protrusions 12 are arranged at intervals along the width direction of the scale 3 (as shown in Figure 5, Y direction), with the two protrusions 12 arranged along the width direction of the scale 3 (i.e., Y direction). Figure 2 , 3 (as shown in Figure 5, Y-direction) spaced out.

[0060] The groove 32 is aligned with the first direction (i.e.) Figure 1 , 5 As shown in the X direction, extending as in some embodiments of this application, the protrusion 12 is aligned with the first direction (i.e., Figure 1 , 5 The mating groove 32 can extend in the X direction (as shown), or the mating protrusion 12 can be constructed as a smaller boss structure. Both of these configurations can guide the mating groove 32 to engage with the mating protrusion 12.

[0061] When the device body 1 is assembled with the scale 3, the mating groove 32 corresponds to the mating protrusion 12, and the mating protrusion 12 and the mating groove 32 are guided to guide the movement of the scale 3 relative to the device body 1, reducing the risk of the scale 3 deviating when moving relative to the device body 1, thereby reducing the installation error of the purlin and improving the reliability of the positioning device 100.

[0062] In some embodiments of this application, such as Figure 2 As shown, the device body 1 defines a receiving space 13, and at least a portion of the scale 3 is received in the receiving space 13.

[0063] The device body 1 defines a receiving space 13. As some embodiments of this application, the receiving space 13 is along a first direction (i.e., Figure 1 , 5 (Extended in the X direction as shown). At least a portion of the scale 3 is housed in the housing space 13. As some embodiments of this application, a portion of the scale 3 can be housed in the housing space 13, that is, the scale 3 has a minimum extended length, meaning the scale 3 cannot be completely housed in the housing space 13. As some embodiments of this application, the entire scale 3 can be housed in the housing space 13, that is, the scale 3 can be completely housed in the housing space 13. This arrangement allows at least a portion of the scale 3 to be housed in the housing space 13, and the positioning device 100 can be reduced in size when not in use, making it easy to carry.

[0064] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the device body 1 has a threaded hole 18, and the locking member 4 has an external thread. The external thread is threadedly engaged with the threaded hole 18, and the locking member 4 can press the scale 3 to lock the scale 3.

[0065] The device body 1 has a threaded hole 18, and the locking member 4 has an external thread. As some embodiments of this application, the locking member 4 can be constructed as a locking bolt. The locking bolt has an external thread, which is threadedly engaged with the threaded hole 18. By rotating the locking bolt, the locking bolt can be brought closer to or away from the scale 3. Rotating the locking bolt so that the locking bolt contacts and presses the scale 3 can lock the scale 3. Rotating the locking bolt so that the locking bolt is separated from the scale 3 can unlock the scale 3.

[0066] This design facilitates fixing the scale 3 to ensure that the spacing between adjacent purlins is the same, reducing purlin installation errors. At the same time, the scale 3 can be adjusted and locked according to the purlin spacing of different photovoltaic brackets, making it highly versatile. Furthermore, the structure is simple and easy to install and replace.

[0067] In some embodiments of this application, such as Figure 3 As shown, the device body 1 includes: a first sub-body 14, a second sub-body 15, and a third sub-body 16. The first sub-body 14 and the second sub-body 15 are arranged along a second direction (i.e., the thickness direction of the mounting plate 221 mentioned above). Figure 2 , 3 The third sub-body 16 is spaced apart in the Z direction (as shown). It is connected between the first sub-body 14 and the second sub-body 15. The first sub-body 14, the second sub-body 15, and the third sub-body 16 together define the receiving space 13. The second direction (i.e., the thickness direction of the mounting plate 221 mentioned above) Figure 2 , 3 The Z direction shown) and the first direction (i.e. Figure 1 , 5 (The X direction shown is perpendicular to the X direction.)

[0068] Wherein, along the second direction (i.e., the thickness direction of the mounting plate 221 mentioned above), Figure 2 , 3(As shown in the Z direction), a first sub-body 14 and a second sub-body 15 are spaced apart, and a third sub-body 16 is connected between the first sub-body 14 and the second sub-body 15. In some embodiments of this application, there are two third sub-body 16s, connected to the corresponding ends of the first sub-body 14 and the corresponding ends of the second sub-body 15. In some embodiments of this application, one third sub-body 16 has its two ends connected between one end of the first sub-body 14 and one end of the second sub-body 15, and the other third sub-body 16 has its two ends connected between the other ends of the first sub-body 14 and the other end of the second sub-body 15. The first sub-body 14, the second sub-body 15, and the third sub-body 16 can be fixedly connected. For example, the connection method of the first sub-body 14, the second sub-body 15, and the third sub-body 16 can be, but is not limited to, welding, snap-fit, bolting, etc., or the first sub-body 14, the second sub-body 15, and the third sub-body 16 can be integrally formed. The first sub-body 14, the second sub-body 15, and the third sub-body 16 together define the containment space 13.

[0069] It should be noted that the second direction (i.e., the thickness direction of the mounting plate 221 mentioned above) Figure 2 , 3 The Z direction shown) and the first direction (i.e. Figure 1 , 5 (The X direction shown is perpendicular to the X direction.)

[0070] This arrangement makes the structure of the device body 1 reasonable, protects the scale 3 housed in the housing space 13, and makes the shape of the device body 1 easy for workers to handle and use.

[0071] As some embodiments of this application, the first mounting hole 11 and the threaded hole 18 are both formed on the first sub-body 14.

[0072] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the second sub-body 15 has a first clearance notch 17 communicating with the receiving space 13, and the sliding mechanism 2 is provided on the first sub-body 14 and passes through the first clearance notch 17.

[0073] Among them, as some embodiments of this application, such as Figure 3 As shown, the device body 1 has two mating protrusions 12, and a first clearance notch 17 is located between the two mating protrusions 12. A sliding mechanism 2 is provided on the first sub-body 14, and the sliding mechanism 2 passes through the first clearance notch 17.

[0074] This arrangement allows part of the sliding mechanism 2 to be housed in the housing space 13, which helps to reduce the size of the positioning device 100 and makes it easier to use. This arrangement also facilitates the disassembly and assembly of the connecting piece 5, making it easier to assemble and disassemble the sliding mechanism 2 from the device body 1.

[0075] In some embodiments of this application, such as Figure 1 As shown, there are multiple sliding mechanisms 2, and the scale 3 has a second clearance notch (not shown in the figure), the second clearance notch is along the first direction (i.e. Figure 1 , 5 Extending in the X direction (as shown), at least one sliding mechanism 2 passes through the second clearance notch.

[0076] The sliding mechanism 2 can be multiple; for example, the number of sliding mechanisms 2 can be two, four, six, etc. As some embodiments of this application, such as... Figure 1 As shown, there are two sliding mechanisms 2, along the first direction (i.e. Figure 1 , 5 (As shown in the X direction), the two sliding mechanisms 2 are arranged in sequence.

[0077] The scale 3 may have a second clearance notch, as in some embodiments of this application, along the width direction of the scale 3 (i.e. Figure 2 , 3 (as shown in Figure 5, in the Y direction), the width of the second clearance notch is slightly larger than the width of the sliding mechanism 2, and one or more sliding mechanisms 2 pass through the second clearance notch. The second clearance notch is along the first direction (i.e., Figure 1 , 5 Extending in the X direction (as shown) reduces the risk of interference between the sliding mechanism 2 and the scale 3 when the scale 3 moves.

[0078] By providing a second clearance notch to the scale 3 and having at least one sliding mechanism 2 pass through the second clearance notch, the risk of interference between the sliding mechanism 2 and the scale 3 when the scale 3 moves can be reduced. Furthermore, the scale 3 and the sliding mechanism 2 can be arranged in an alternating manner, making the components of the positioning device 100 more compact and thus improving space utilization.
