Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and more specifically, to a photovoltaic mounting bracket and a photovoltaic module system. Background Technology

[0002] Balcony photovoltaic (PV) modules are small-scale solar power generation systems typically installed in residential spaces such as balconies, terraces, or windowsills. They are suitable for urban residents to generate clean energy using limited space. Balcony PV modules do not require roof or ground space and can be directly fixed to balcony railings, exterior walls, or windowsills, making them suitable for urban environments such as apartments and high-rise buildings.

[0003] A typical balcony photovoltaic system includes a photovoltaic module and a photovoltaic mounting bracket. When the photovoltaic equipment is not in use or the balcony needs to be used for other purposes, the photovoltaic mounting bracket cannot be folded, occupies a lot of space, and will cause space obstruction and inconvenience in placement.

[0070] This application discloses a photovoltaic mounting bracket that is foldable, so that it can be folded up when not in use to reduce space occupation;

[0071] This application discloses a photovoltaic module system having the aforementioned photovoltaic mounting bracket.

[0072] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0073] like Figure 1 and Figure 2 As shown in the embodiments of this application, the photovoltaic mounting bracket is used to support the photovoltaic module 400, and is particularly suitable for installation in home spaces such as balconies, terraces or windowsills; of course, it can also be installed in other locations as needed, and is not limited to the home spaces listed above.

[0074] The photovoltaic mounting bracket may include a bracket body 10 for connecting to the photovoltaic module 400. The bracket body 10 includes: a mounting pole, hinged to the photovoltaic module 400 for supporting the photovoltaic module 400; a hanging component 170, rotatably mounted on the mounting pole for fixing to the installation position; and a diagonal brace 130, the first end of which is hinged to the photovoltaic module 400 to adjust the angle between the mounting pole and the photovoltaic module 400.

[0075] When the photovoltaic module system is not in use, the diagonal brace 130 can be removed from the support of the mounting pole, so that the mounting pole and the diagonal brace 130 can be folded and pressed against the photovoltaic module 400. This reduces the overall size, reduces the space occupied, facilitates other activities on the balcony, and makes transportation easier and reduces transportation costs.

[0076] It should be noted that the first end of the aforementioned diagonal brace 130 is hinged to the photovoltaic module 400, and the second end can cooperate with the mounting pole to adjust the angle between the mounting pole and the photovoltaic module 400. Specifically, the second end of the diagonal brace 130 can be detachably connected to the mounting pole, and the position of the second end of the diagonal brace 130 on the mounting pole can be adjusted by detachment, thereby adjusting the angle between the photovoltaic module 400 and the mounting pole; or the second end of the diagonal brace 130 can be slidably cooperated with the mounting pole, and the position of the second end of the diagonal brace 130 on the mounting pole can be adjusted by sliding, thereby adjusting the angle between the photovoltaic module 400 and the mounting pole; or the second end of the diagonal brace 130 is hinged to the mounting pole, and the mounting pole is a telescopic structure, and the relative position of the diagonal brace 130 and the mounting pole can be adjusted by telescopic movement, thereby adjusting the angle between the photovoltaic module 400 and the mounting pole.

[0077] The mounting pole being hinged to the photovoltaic module 400 can be understood as being hinged to any position on the photovoltaic module, such as the back or frame. Any hinged connection between the mounting pole and the photovoltaic module 400 is within the scope of this application. Similarly, the second end of the diagonal brace 130 can also be hinged to any position on the photovoltaic module 400, such as the back or frame.

[0078] The number of the aforementioned support bodies can be one or at least two. When there is only one support body 10, it is typically arranged in the middle of the back of the photovoltaic module 400. However, this does not mean that a single support body 10 can only be located in the middle of the back of the photovoltaic module 400; it can also be located at the edge of the photovoltaic module 400. This application focuses on the case where there are two support bodies 10.

[0079] The number of support bodies 10 includes two, namely a first support body 100 and a second support body 200, which are respectively connected to two opposite frames of the photovoltaic module 400.

[0080] The photovoltaic mounting bracket includes a first bracket body 100 and a second bracket body 200, which are used to fix the photovoltaic module 400 on both sides respectively. Of course, in order to improve stability, an intermediate bracket can also be set between the first bracket body 100 and the second bracket body 200 to further reinforce the photovoltaic module 400.

[0081] like Figure 3 and Figure 4 As shown, in this embodiment, the first support body 100 and the second support body 200 may include mounting poles, hanging components 170, and diagonal bracing components 130. It should be noted that the first support body 100 and the second support body 200 have the same basic structure. Since the first support body 100 and the second support body 200 are fixed to both sides of the photovoltaic module 400, the only difference lies in the direction of the components connected to the photovoltaic module 400. Of course, it is not impossible that for the purpose of installing other components, only one of the first support body 100 and the second support body 200 may be installed. For ease of understanding, in this embodiment, the structurally identical parts of the first support body 100 and the second support body 200 will be described uniformly.

[0082] The aforementioned mounting pole and diagonal brace 130 are directly hinged to the photovoltaic module or indirectly hinged to the photovoltaic module. Taking indirect hinge as an example, the mounting pole is hinged to a first frame bracket 150, and the first end of the diagonal brace 130 is hinged to a second frame bracket 160. The first frame bracket 150 and the second frame bracket 160 are used to fix the photovoltaic module 400.

[0083] A first frame retainer 150 is hinged to the mounting pole. The first frame retainer 150 can be attached to the frame 401 of the photovoltaic module 400 and can be locked with fasteners to achieve relative fixation between the first frame retainer 150 and the photovoltaic module 400. The angle between the first frame retainer 150 and the mounting pole can be adjusted to accommodate the angle adjustment of the photovoltaic module 400. It should be noted that the mounting pole may also be directly hinged or fixed to the frame 401 of the photovoltaic module 400 without hinged first frame retainer 150.

[0084] The mounting bracket 170 is rotatably mounted on the mounting pole for fixing to the installation position. This rotatability allows the mounting bracket 170 to be rotated, changing its position between a hooked position and a folded position. When needed, the mounting bracket 170 can be rotated to the hooked position; when not in use and requiring storage or transport, it can be rotated to the folded position, reducing the size of the photovoltaic mounting bracket in the thickness direction of the photovoltaic module 400. The rotation axis of the mounting bracket 170 can be parallel to the mounting pole, ensuring that when the mounting bracket 170 is in the hooked position, the mounting groove that mates with the object to be fixed is perpendicular to the plane of the two mounting poles; when the mounting bracket 170 is in the folded position, the mounting groove that mates with the object to be fixed is coplanar with the plane of the two mounting poles, further reducing the space occupied by the mounting bracket 170.

[0085] This embodiment does not limit the specific type of the installation location. It can be a wall of a balcony or terrace, a balcony railing, or other locations such as an exterior wall of a building or a support frame. Those skilled in the art will understand that any location that can be used to arrange photovoltaic modules is applicable to the photovoltaic mounting bracket disclosed in this embodiment.

[0086] The first end of the diagonal brace 130 is hinged to a second frame retainer 160. The second frame retainer 160 can be designed to have the same structure as the first frame retainer 150, or its structure can be designed differently depending on the actual installation scenario to match specific installation requirements. The second frame retainer 160 can be attached to the frame 401 of the photovoltaic module 400 and locked with fasteners to achieve relative fixation between the second frame retainer 160 and the photovoltaic module 400. It should be noted that the first end of the diagonal brace 130 may also be directly hinged or fixed to the frame 401 of the photovoltaic module 400 without hinged to the second frame retainer 160.

[0087] The first frame connector 150 and the second frame connector 160 of the first support body 100 are used to fix to the frame 401 on one side of the photovoltaic module 400. The first frame connector 150 and the second frame connector 160 of the second support body 200 are used to fix to the frame 401 on the other side of the photovoltaic module 400. The second end of the diagonal brace 130 is hinged to the mounting pole. The angle of the photovoltaic module 400 can be adjusted by fixing the second frame connector 160 to different positions on the frame 401, or by hinged the second end of the diagonal brace 130 to different positions on the mounting pole.

[0088] The photovoltaic mounting bracket disclosed in this application can be fixed to both sides of the photovoltaic module 400 via a first bracket body 100 and a second bracket body 200, thereby enabling the photovoltaic module 400 to be installed on the photovoltaic mounting bracket. The photovoltaic mounting bracket and the photovoltaic module 400 mounted on it can be fixed in the installation position using the mounting bracket 170. One end of the diagonal brace 130 is connected to the photovoltaic module 400, and the other end is detachably hinged to the mounting pole.

[0089] When the photovoltaic module system is not in use, the diagonal brace 130 can be disengaged from the mounting pole, allowing the second end of the diagonal brace 130 to slide along the mounting pole. This allows the mounting pole and the diagonal brace 130 to fold and adhere tightly to the photovoltaic module 400, reducing the overall size and space occupation. This facilitates other activities on the balcony, makes transportation easier, and reduces transportation costs. Furthermore, the rotatable mounting bracket 170 can also be folded and adhered tightly to the photovoltaic module 400. Folding the mounting bracket 170 further reduces its space occupation, further minimizing space usage.

[0090] To improve the stability of the fixed photovoltaic module 400, the photovoltaic mounting bracket disclosed in this embodiment may further include a lower crossbeam assembly 300. One end of the lower crossbeam assembly 300 is connected to the mounting pole of the first bracket body 100, and the other end is connected to the mounting pole of the second bracket body 200. In this embodiment, the lower crossbeam assembly 300 is provided between the first bracket body 100 and the second bracket body 200 to connect them, which can constrain the positions of the first bracket body 100 and the second bracket body 200 and prevent them from moving away from each other.

[0091] For example, the first frame connector 150 can be disposed at the upper end of the mounting pole. When the first frame connectors 150 of the first bracket body 100 and the second bracket body 200 are respectively clamped to both sides of the photovoltaic module 400, the photovoltaic module 400 can be used to constrain the upper ends of the first bracket body 100 and the second bracket body 200. The lower crossbeam assembly 300 can be connected to the lower end of the mounting pole of the first bracket body 100 and the second bracket body 200, and the lower crossbeam assembly 300 can be used to constrain the lower ends of the first bracket body 100 and the second bracket body 200.

[0092] like Figure 1 As shown, in a specific embodiment of this application, the lower crossbeam assembly 300 includes a lower crossbeam body 301 and a fixing plate 302. The two ends of the lower crossbeam body 301 are respectively connected to the mounting posts of the first support body 100 and the second support body 200. To facilitate the connection between the lower crossbeam body 301 and the mounting posts, as shown... Figure 5 As shown, a crossbeam connecting seat 122 is provided on the mounting pole, and the crossbeam connecting seat 122 can be fixed to the mounting pole by fasteners. The crossbeam connecting seat 122 is provided with a groove, and fixing holes are provided on both sides of the groove. The end of the lower crossbeam 301 is inserted into the groove and secured by fasteners passing through the fixing holes on the side walls of the groove and the fixing holes at the end of the lower crossbeam 301, thus achieving the connection between the lower crossbeam 301 and the crossbeam connecting seat 122. It should be noted that the above embodiment is only an example of the connection method between the lower crossbeam 301 and the mounting pole, and does not constitute a constraint on the scope of protection of this application.

[0093] The fixing plate 302 is fixed to the lower crossbeam 301 by the plate fastener 303, so as to clamp the object to be fixed between the fixing plate 302 and the lower crossbeam 301. In this embodiment, a fixing structure for fixing the object to be fixed can be added to the lower crossbeam 301, so that the photovoltaic mounting bracket has multiple fixing points for fixing the object to be fixed (e.g., the hanger 170 and the fixing plate 302).

[0094] Taking the application of this photovoltaic mounting bracket to a balcony with railings as an example, the mounting bracket 170 is used to hang on the balcony railing, and the fixing plate 302 and the lower crossbeam 301 can be used to clamp the balcony railing as the object to be fixed. Since the balcony railing has multiple railings arranged in parallel along the height direction, the mounting bracket 170 and the fixing plate 302 can be fixedly hung on railings at different heights respectively.

[0095] For example, the hanger 170 can be mounted on the top railing, and the fixing plate 302 can be fixed to the railing at the same height as the lower crossbeam 301. The hanger 170 can be mounted on a horizontal railing (e.g., a horizontally extending railing), and the fixing plate 302 and the lower crossbeam 301 can clamp the horizontal railing or the longitudinal railing (e.g., a vertically extending railing).

[0096] When the fixed pressure plate 302 and the lower crossbeam 301 are used to clamp the longitudinal railing, multiple crossbeam mounting holes 3011 can be provided at intervals on the lower crossbeam 301. The crossbeam mounting holes 3011 are used to pass through the pressure plate fasteners 303. The appropriate crossbeam mounting holes 3011 can be selected according to the position of the longitudinal railing so that the fixed pressure plate 302 can press the longitudinal railing tightly.

[0097] A slotted hole can be provided on the fixed pressure plate 302 for inserting pressure plate fasteners 303. One fixed pressure plate 302 can be fitted with two pressure plate fasteners 303. The longitudinal railing can pass between the two pressure plate fasteners 303. By tightening the pressure plate fasteners 303, the longitudinal railing can be pressed between the fixed pressure plate 302 and the lower crossbeam 301. It should be noted that nuts are required for the pressure plate fasteners 303 to ensure their secure fastening. Furthermore, multiple fixed pressure plates 302 can be provided to simultaneously fix multiple points, improving the stability of the fixation.

[0098] To accommodate balconies of varying heights, the mounting poles can be telescopic, allowing for length adjustments based on the installation requirements. The mounting bracket 170 and the lower crossbeam assembly 300 are respectively positioned at both ends of the mounting pole. Adjusting the pole length also allows for adjustment of the distance between the mounting bracket 170 and the lower crossbeam assembly 300. When the photovoltaic mounting bracket is used on a balcony with railings, if the mounting bracket 170 and the lower crossbeam assembly 300 are used to fix themselves to the horizontal railings of the balcony railing, adjusting the distance between them ensures that after the mounting bracket 170 is fixed to the corresponding horizontal railing, the lower crossbeam assembly 300 can also be aligned with the corresponding horizontal railing. This prevents the lower crossbeam assembly 300 from failing to align effectively with the corresponding horizontal railing, thus ensuring proper fixation.

[0099] like Figure 5 As shown, in this embodiment, the mounting pole may include a first pole body 110 and a second pole body 120 that are nested and slidably fitted together. For example, the second pole body 120 may be sleeved on the outside of the first pole body 110. The first pole body 110 and the second pole body 120 are not limited to tubular structures and may also be... Figure 5 The channel steel structure shown is designed to reduce weight.

[0100] The mounting bracket 170 is mounted on the first upright 110, and a micro-inverter mounting plate 140 can also be mounted on the first upright 110, on which the inverter can be fixed. The lower crossbeam assembly 300 is connected to the second upright 120. By sliding the first upright 110 and the second upright 120, the length of the mounting pole can be adjusted, that is, the distance between the mounting bracket 170 and the lower crossbeam assembly 300 can be adjusted, thereby adjusting the position of the photovoltaic mounting bracket's installation point to match the actual installation scenario.

[0101] The second upright 120 is sleeved on the outside of the first upright 110, and a locking block 121 for locking the second upright 120 and the first upright 110 is connected to the second upright 120. The locking block 121 increases the friction between the second upright 120 and the first upright 110, thereby limiting the relative sliding between the second upright 120 and the first upright 110. When it is necessary to adjust the length of the installed upright, the locking block 121 needs to be loosened first, so that the second upright 120 and the first upright 110 can slide relative to each other; when the installed upright is adjusted to a suitable length, the locking block 121 is used to lock the second upright 120 and the first upright 110 to keep the installed upright at the corresponding length.

[0102] In one specific embodiment of this application, the first upright 110 is provided with an adjusting groove 111, and the locking block 121 includes a locking slider and a locking screw that is threadedly engaged with the locking slider. The locking slider is slidably engaged with the adjusting groove 111, and the second upright 120 is provided with a locking hole through which the locking screw passes. The locking slider is provided with a threaded hole, and the screw end of the locking screw passes through the locking hole on the second upright 120 and is threadedly engaged with the threaded hole of the locking slider. By rotating the locking screw, the position of the locking slider can be adjusted, and by changing the position of the locking slider, the friction between the locking slider and the side wall of the adjusting groove 111 can be adjusted. When the locking slider abuts against the side wall of the adjusting groove 111, the first upright 110 and the second upright 120 are locked together. When the clamping force between the locking slider and the side wall of the adjusting slide groove 111 is reduced, the locking slider can slide along the adjusting slide groove 111, thereby enabling the relative sliding of the first upright body 110 and the second upright body 120.

[0103] The locking slider and the adjusting slide 111 should have a limiting structure for the direction of rotation, that is, the locking slider can only slide along the adjusting slide 111 and cannot rotate within the adjusting slide 111, so that the locking slider will not rotate with the locking screw when the locking screw is rotated.

[0104] In this embodiment, multiple locking blocks 121 can be provided to ensure reliable locking. Of course, only one locking block 121 can be provided; this embodiment does not limit the specific number of locking blocks 121.

[0105] like Figure 4 As shown, in this embodiment, the mounting component 170 may include a first mounting component 171 and a second mounting component 172. The first mounting component 171 is fixed to the mounting pole, specifically, the first mounting component 171 is fixed to the end of the first pole body 110 away from the second pole body 120. Of course, if the mounting pole is a non-retractable structure, the first mounting component 171 can be directly fixed to one end of the mounting pole.

[0106] The second mounting component 172 is locked to the first plate of the first mounting component 171 by a locking screw 173, and the first plate of the second mounting component 172 is provided with a first adjusting slot hole through which the locking screw 173 passes. The locking screw 173 can be a wing fastener, specifically including a screw and a wing nut. The screw can be fixed to the first plate of the first mounting component 171 and passes through the first adjusting slot hole. The wing nut is threadedly engaged with the screw, which can press the first plate of the second mounting component 172 onto the first plate of the first mounting component 171.

[0107] An adjustable mounting groove 174 is formed between the second plate of the first mounting member 171 and the second plate of the second mounting member 172. Specifically, the width of the mounting groove 174 can be adjusted according to the size of the object to be fixed. Taking the mounting member 170 mounted on the railing as an example, first loosen the locking screw 173 (e.g., loosen the wing nut), then clamp the railing into the mounting groove 174 between the second plate of the first mounting member 171 and the second plate of the second mounting member 172, and then manually slide the second mounting member 172 so that the second plate of the first mounting member 171 and the second plate of the second mounting member 172 move closer to each other. After the second plate of the first mounting member 171 and the second plate of the second mounting member 172 clamp the railing, tighten the locking screw 173 (e.g., loosen the wing nut).

[0108] Both the first mounting member 171 and the second mounting member 172 can be L-shaped plates, meaning that the first and second plates of both mounting members 171 and 172 are perpendicular to each other. However, the dimensions of the first and second plates of the first and second mounting members 171 and 172 can be designed according to installation requirements. For example, the first plate of the first mounting member 171 needs to support the first plate of the second mounting member 172, therefore the length of the first plate of the first mounting member 171 does not need to be too large. However, the first plate of the second mounting member 172 needs to be provided with a first adjustment slot, therefore the length of the first plate of the second mounting member 172 should be greater than the length of the first plate of the first mounting member 171.

[0109] The first mounting bracket 171 and the second mounting bracket 172 may have anti-slip teeth on the side that contacts the object to be fixed (e.g., a railing) to improve connection strength and safety. The second mounting bracket 172 can be rotated to fit snugly against the side of the photovoltaic module 400 after the locking screw 173 is loosened, thereby reducing the overall packaging size of the system.

[0110] Furthermore, the mounting component 170 may also include a locking screw (not shown in the figure), the second plate of the second mounting component 172 is provided with a second adjusting slot, and the second plate of the first mounting component 171 is provided with a plurality of spaced locking screw holes. The locking screw passes through the second adjusting slot and engages with one of the locking screw holes. That is, the locking screw can be used to close the open side of the mounting groove 174, making the mounting groove 174 a four-sided closed structure, surrounding the railing or other fixed body inside, further improving the reliability of the connection.

[0111] like Figure 10 As shown, both the first frame retainer 150 and the second frame retainer 160 may include a hinge arm 151 and a retaining groove 152 disposed on the hinge arm 151. The retaining groove 152 is used to cover the frame 401 of the photovoltaic module 400 and is tightened by a set screw. The hinge arm 151 of the first frame retainer 150 is hinged to the mounting pole, and the hinge arm 151 of the second frame retainer 160 is hinged to the diagonal brace 130.

[0112] The hinge arm 151 can also be a groove structure. Figure 10 In the illustrated scheme, the depth direction of the groove of the hinge arm 151 is perpendicular to the depth direction of the clamping groove 152. Multiple hinge holes can be provided on the hinge arm 151 to select which hinge hole the hinge shaft is placed in based on the actual installation scenario. Screw holes can be provided on the bottom wall of the hinge arm 151. Since the bottom wall of the hinge arm 151 is relatively thin, it is difficult to create screw holes, and the depth of the screw holes is easily insufficient, affecting the locking strength. Therefore, rivet nuts can be provided on the bottom wall of the hinge arm 151. Set screws cooperate with the rivet nuts and extend into the inner wall of the clamping groove 152 to tighten the frame 401 of the photovoltaic module 400. Multiple rivet nuts can be provided on the bottom wall of the hinge arm 151, allowing for the simultaneous installation of multiple set screws, improving the reliability of the tightening.

[0113] It should be noted that in this application, for other parts or other locations where screw holes are required, the rivet nut solution can be used.

[0114] Since the cross-sectional width of the diagonal brace 130 is smaller than that of the mounting pole, the diagonal brace 130 can be hinged within the groove of the hinge arm 151; the mounting pole can be hinged outside the groove of the hinge arm 151. That is, the diagonal brace 130 mates with the inner wall of the hinge arm 151, and the mounting pole mates with the outer wall of the hinge arm 151.

[0115] like Figures 5-7 As shown in a specific embodiment of this application, a plurality of positioning holes 112 are spaced apart on the mounting pole, and a positioning component 131 is provided at the second end of the diagonal brace 130. The positioning component 131 includes a positioning shaft 1312, which is used to cooperate with the positioning holes 112. By cooperating with different positioning holes 112, the angle of the photovoltaic module 400 can be adjusted.

[0116] like Figure 8 and Figure 9 As shown, to facilitate the adjustment of the angle of the photovoltaic module 400, i.e., to facilitate the switching of the positioning shaft 1312 between different positioning holes 112, in a specific embodiment of this application, the positioning component 131 may further include an elastic reset member and an adjusting member 1311. There are two positioning shafts 1312, which respectively cooperate with the positioning holes 112 on the two side walls of the mounting pole, i.e., the two positioning shafts 1312 extend to both sides to be inserted into the positioning holes 112 on the two side walls of the mounting pole.

[0117] The elastic reset member is used to push the two positioning shafts 1312 to move away from each other. That is, the elastic reset member can push the two positioning shafts 1312 into the positioning hole 112 and keep them in the positioning hole 112 to prevent them from coming out of the positioning hole 112.

[0118] Adjusting member 1311 is used to push the two positioning shafts 1312 towards each other and compress the elastic reset member. Adjusting member 1311 compresses the elastic reset member and drives the two positioning shafts 1312 towards each other, causing the two positioning shafts 1312 to disengage from the positioning holes 112. After the positioning shafts 1312 disengage from the positioning holes 112, the position of the diagonal brace 130 on the mounting pole can be adjusted, thereby changing the angle of the photovoltaic module 400. When the angle of the photovoltaic module 400 is adjusted to a suitable angle, adjusting member 1311 releases the constraint on the positioning shafts 1312, causing the elastic reset member to push the positioning shafts 1312 back to their original position, inserting the positioning shafts 1312 into the corresponding positioning holes 112.

[0119] In this embodiment, two positioning shafts 1312 are designed, allowing them to move closer and further apart. By using the adjusting member 1311 to drive the two positioning shafts 1312 closer together, the two positioning shafts 1312 can be disengaged from the positioning holes 112. This releases the hinge connection between the diagonal brace 130 and the mounting pole without removing the positioning shafts 1312. After adjusting to the appropriate position, simply releasing the constraint on the positioning shafts 1312 by the adjusting member 1311 allows the positioning shafts 1312 to be pushed into the corresponding positioning holes 112 under the action of the elastic reset member (provided that the positioning shafts 1312 and the corresponding positioning holes 112 are coaxial).

[0120] like Figure 6 and Figure 8 As shown, in one specific embodiment, the adjusting member 1311 is provided with an extrusion groove 13110, and the extrusion walls 13111 on both sides of the extrusion groove 13110 gradually approach each other from one end to the other. The extrusion walls 13111 on both sides of the extrusion groove 13110 can be curved or inclined plane.

[0121] A limiting disc 1315 is provided at the end of the positioning shaft 1312 away from the positioning hole 112. The limiting disc 1315 is located in the extrusion groove 13110 and can slide along the extrusion wall 13111. The two ends of the elastic reset member abut against the two limiting discs 1315 respectively, so that the limiting discs 1315 abut against the extrusion wall 13111. The elastic reset member can be a helical spring 1314. A positioning groove can be provided on the limiting disc 1315, and the end of the helical spring 1314 is embedded in the positioning groove to achieve positioning of the helical spring 1314 and the limiting disc 1315.

[0122] To improve the smoothness of the sliding of the limiting disc 1315 along the extrusion wall 13111, the portion of the limiting disc 1315 that contacts the extrusion wall 13111 can be a guide slope. When the adjusting member 1311 is pulled, the positioning shaft 1312 cannot move due to the constraint of the positioning hole 112, so the limiting disc 1315 cannot move with the adjusting member 1311. This causes the limiting disc 1315 to slide relative to the extrusion wall 13111 when the adjusting member 1311 is pulled. When the direction of movement of the adjusting member 1311 is such that the limiting disc 1315 moves towards the side of the two extrusion walls 13111 that are closer to each other, the two extrusion walls 13111 will push the two limiting discs 1315 closer to each other, thereby causing the positioning shafts 1312 connected to the two limiting discs 1315 to move closer to each other and thus exit from the positioning hole 112.

[0123] When the adjusting member 1311 is released, the coil spring 1314 can push the two limiting discs 1315 to move away from each other, so that the positioning shaft 1312 is inserted into the positioning hole 112. At the same time, the limiting discs 1315 will slide relative to the pressing wall 13111, pushing the adjusting member 1311 to reset. If the elastic force of the coil spring 1314 cannot push the adjusting member 1311 to reset, the operator can manually push the adjusting member 1311 to reset, so that the adjusting member 1311 loses its restraining effect on the limiting discs 1315, and then the coil spring 1314 can push the positioning shaft 1312 to insert into the positioning hole 112.

[0124] The adjusting component 1311 can be a bent sheet metal part or other structural parts, and an adjusting handle 13112 can be provided on the adjusting component 1311. The adjusting handle 13112 allows the operator to easily pull the adjusting component 1311 to move.

[0125] like Figure 7 and Figure 9 As shown, in another specific embodiment, the adjusting member 1311 includes a first adjusting part 1311a and a second adjusting part 1311b connected to each other. Specifically, the adjusting member 1311 can be a U-shaped structural member formed by bending a sheet metal, and the two plates of the U-shaped structural member can be the first adjusting part 1311a and the second adjusting part 1311b, respectively.

[0126] Both the first adjusting part 1311a and the second adjusting part 1311b are provided with adjusting grooves 13114, and the length of the adjusting grooves 13114 should be sufficient to meet the movement range of the adjusting member 1311. The ends of the first adjusting part 1311a and the second adjusting part 1311b are provided with adjusting arms 13113, and the adjusting arms 13113 of the first adjusting part 1311a and the second adjusting part 1311b gradually approach each other from one end to the other.

[0127] The end of the positioning shaft 1312 furthest from the positioning hole 112 passes through the adjusting groove 13114 and is connected to the elastic reset member. That is, when the elastic reset member is compressed, it can drive the positioning shaft 1312 to move closer to each other. The elastic reset member is fixed on the inclined support member 130, that is, the positional relationship between the elastic reset member and the inclined support member 130 remains unchanged.

[0128] The two ends of the elastic reset member abut against the adjusting arms 13113 of the first adjusting part 1311a and the second adjusting part 1311b, respectively, and can slide along the adjusting arms 13113. Specifically, the elastic reset member can be a V-shaped spring 1316, with its two spring arms engaging with the first adjusting part 1311a and the second adjusting part 1311b, respectively. That is, the V-shaped spring 1316 is disposed between the first adjusting part 1311a and the second adjusting part 1311b, with one spring arm abutting against the first adjusting part 1311a and the other spring arm abutting against the second adjusting part 1311b.

[0129] In order to improve the smoothness of the relative sliding between the spring arm of the V-shaped spring 1316 and the adjusting arm 13113, an arc-shaped guide part 13161 is provided on the spring arm of the V-shaped spring 1316, and the arc-shaped guide part 13161 slides in cooperation with the adjusting arm 13113.

[0130] When the adjusting member 1311 is pulled, the V-shaped spring piece 1316 is fixed on the inclined support member 130 and cannot move. As a result, when the adjusting member 1311 is pulled, the arc-shaped guide part 13161 will slide relative to the adjusting arm 13113. When the moving direction of the adjusting member 1311 is such that the arc-shaped guide part 13161 moves towards the side of the two adjusting arms 13113 that are closer to each other, the two adjusting arms 13113 will push the two arc-shaped guide parts 13161 closer to each other, which in turn causes the two spring arms of the V-shaped spring piece 1316 to move closer to each other. The positioning shafts 1312 connected to the two spring arms also move closer to each other, and thus exit from the positioning hole 112.

[0131] When the adjusting member 1311 is released, the V-shaped spring 1316 resets, causing the positioning shaft 1312 to insert into the corresponding positioning hole 112. Simultaneously, the arc-shaped guide portion 13161 slides relative to the adjusting arm 13113, pushing the adjusting member 1311 back to its original position. If the elastic force of the V-shaped spring 1316 is insufficient to push the adjusting member 1311 back to its original position, the operator can manually push the adjusting member 1311 back to its original position, causing the adjusting member 1311 to lose its constraint on the arc-shaped guide portion 13161. Then, the V-shaped spring 1316 can push the positioning shaft 1312 into the positioning hole 112.

[0132] like Figures 6-9 As shown, the positioning assembly 131 may further include a limiting piece 1313, which is sleeved on the positioning shaft 1312 and has a diameter larger than that of the positioning shaft 1312. The limiting piece 1313 can be supported in the groove of the mounting pole (the mounting pole is a channel steel structure). The limiting piece 1313 can support the positioning shaft 1312, so that the positioning shaft 1312 and the positioning hole 112 can be kept at the same height, thereby enabling the positioning shaft 1312 to be aligned with the positioning hole 112.
