Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of transportation machinery, and in particular to a tarpaulin frame with an anti-deformation function and a truck tarpaulin system. Background Art

[0002] During the transportation or storage of goods, in order to prevent the goods in the cargo box from being blown away by the wind, or to prevent dust and other pollutants that may exist in the cargo box from entering the air and polluting the environment, or to protect the goods, tarpaulins are usually used to wrap and cover the goods. Traditionally, the manual method of covering the tarpaulin is time-consuming and labor-intensive, and often requires multiple people to complete it. The efficiency is very low and it is difficult to meet the increasing freight requirements; and sometimes the staff are required to climb onto the carriage to operate, which not only increases the burden on the staff, but is also very dangerous and increases the risk of injury to the staff.

[0003] Based on this, automatic tarpaulin devices that can automatically cover cargo with tarpaulin have appeared on the market to replace manual covering. Specifically, the automatic tarpaulin device is usually set on the outside of the truck compartment, including a tarpaulin cover and a tarpaulin frame connected to each other, and can drive the tarpaulin cover to move along the contour of the tarpaulin frame through a motor, thereby realizing the opening and closing of the tarpaulin on the top of the compartment. Among them, the tarpaulin frame is generally composed of a fixedly connected cross beam and side beams, the side beams are parallel to the vertical beams of the compartment, and the cross beams are perpendicular to the vertical beams of the compartment.

[0004] When the car body is deformed due to the force of squeezing, the deformation can be transmitted to the tarpaulin frame in contact with the car body, so that the side beam or cross beam also deforms. The deformation of the side beam or cross beam is not conducive to maintaining the structural stability of the tarpaulin frame itself, and on the other hand, it will greatly affect the stability of the movement of the tarpaulin cover relative to the tarpaulin frame, making it impossible for the tarpaulin cover to move smoothly along the contour of the tarpaulin frame, thereby increasing the possibility of failure of the automatic tarpaulin device. Summary of the invention

[0005] In view of the above problems, the embodiments of the present invention provide a tarpaulin frame and a truck tarpaulin system with an anti-deformation function to solve the problem that the tarpaulin frame is deformed due to the deformation of the vehicle compartment, thereby causing the automatic tarpaulin device to fail.

[0006] In a first aspect, an embodiment of the present invention provides a tarpaulin frame with an anti-deformation function, comprising:

[0007] A horizontal bar having a first contact surface at a bottom end;

[0008] A stake located below the horizontal bar, having a second contact surface at the top end;

[0009] The guide components connected to the horizontal bar and the upright stakes respectively include:

[0010] A fixing frame is formed on one of the first contact surface and the second contact surface and has a through buffer space;

[0011] A mounting seat matching the fixing frame is formed on the other of the first contact surface and the second contact surface and has a mounting groove opening toward the fixing frame;

[0012] The two ends of the guide member can pass through the buffer space and be respectively connected to the side walls of the mounting groove, and in response to the deformation of the tarpaulin frame, the guide member can limit the relative displacement between the fixing frame and the mounting seat in the buffer space.

[0013] In some embodiments, the crossbar has a horizontal segment and a vertical segment, and a bending segment respectively connected to the horizontal segment and the vertical segment, and the first contact surface is formed on the bottom surface of the vertical segment.

[0014] In some embodiments, the fixing frame and the vertical section are integrally formed;

[0015] The mounting base and the pile are integrally formed.

[0016] In some embodiments, the fixing frame is provided with a fixing hole, and one of the first contact surface and the second contact surface is provided with an assembly hole; the mounting seat is provided with a mounting hole, and the other of the first contact surface and the second contact surface is provided with a connection hole;

[0017] The guide assembly also includes:

[0018] The fastener can pass through the fixing hole to cooperate with the assembly hole, and pass through the mounting hole to cooperate with the connecting hole, so as to realize the detachable connection between the fixing frame and the cross bar, and the mounting seat and the pile.

[0019] In some embodiments, the guide member is a roller, and the roller comprises:

[0020] The roller shaft has two ends fixedly connected to the side walls of the mounting groove;

[0021] The roller body sleeved on the outer side of the roller shaft has a pair of stoppers extending along its radial direction on its edge, and the distance between the pair of stoppers is not less than the width of the fixed frame.

[0022] In some embodiments, there are two rollers, which are respectively arranged on two sides of the center line of the pile.

[0023] In some embodiments, the ratio of the length of the fixing frame to the width of the vertical segment is between 1.5-1.

[0024] In some embodiments, there are two horizontal bars and four vertical stakes, and the four vertical stakes correspond to the two horizontal bars in pairs;

[0025] There are two guide assemblies, which are respectively arranged on both sides of any cross bar.

[0026] In some embodiments, there are two horizontal bars and four vertical stakes, and the four vertical stakes correspond to the two horizontal bars in pairs;

[0027] There are four guide assemblies, which are respectively arranged on both sides of the two horizontal bars.

[0028] In a second aspect, an embodiment of the present invention further provides a truck tarpaulin system, comprising a tarpaulin cover and a tarpaulin frame as described above, wherein the cross bar is provided with a guide member, and the tarpaulin cover is provided with a transmission member, and the transmission member and the guide member cooperate to enable the tarpaulin cover to move along the contour of the tarpaulin frame.

[0029] Due to the adoption of the above technical solution, the technical effects achieved by the present invention are as follows:

Among them, the guide assembly includes a fixed frame, a mounting seat and a guide member, one of the fixed frame and the mounting seat is set on the first contact surface, and the other is set on the second contact surface. Through the cooperation of the guide member and the fixed frame, the displacement between the fixed frame and the mounting seat can be limited in the buffer space. This setting method allows the horizontal bar and the stake of the tarpaulin frame to move relative to each other when the tarpaulin frame is impacted by external force, and the external force is consumed in the buffer space, thereby greatly reducing the stress that may be generated between the two, so as to avoid adverse deformation of the tarpaulin frame as much as possible, and then help to ensure the stability of the overall structure of the tarpaulin frame.

[0031] In addition, the truck tarpaulin system provided by the present invention, through the arrangement of the above-mentioned tarpaulin frame, is conducive to ensuring the stability and reliability of the movement of the tarpaulin cover relative to the tarpaulin frame, so that the tarpaulin cover can move smoothly along the contour of the tarpaulin frame in more scenarios, greatly reducing the possibility of failure of the truck tarpaulin system.

[0032] The above description is only an overview of the technical solution of the embodiment of the present invention.

[0050] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0051] Reference Figure 1-Figure 6 As shown, an embodiment of the present invention provides a tarpaulin frame with an anti-deformation function, including a horizontal bar 100 and a stake 200 located below the horizontal bar 100, and a guide assembly 300 connected to the horizontal bar 100 and the stake 200 respectively. Among them, the bottom end of the horizontal bar 100 has a first contact surface 110, and the top end of the stake 200 has a second contact surface 210; the guide assembly 300 includes a fixed frame 310, a mounting seat 320 and a guide member 330, the fixed frame 310 is formed on one of the first contact surface 110 and the second contact surface 210, and has a through buffer space 311; the mounting seat 320 matches the fixed frame 310, and is formed on the other of the first contact surface 110 and the second contact surface 210, and has a mounting groove 321 opening toward the fixed frame 310; both ends of the guide member 330 can pass through the buffer space 311 and are respectively connected to the side walls of the mounting groove 321, and in response to the deformation of the tarpaulin frame, the guide member 330 can limit the relative displacement between the fixed frame 310 and the mounting seat 320 in the buffer space 311.

[0052] It should be noted that the tarpaulin rack in the present application is usually placed against the outside of a truck compartment. Since there are many different types of truck compartments, such as a cargo truck compartment, a flatbed truck compartment, a curtain-side truck compartment and a dump truck compartment, and the sizes, specifications and structures of different types of truck compartments are more or less different, when the user installs the tarpaulin rack on different types of truck compartments, the user can appropriately adjust the sizes and specifications of components such as the cross bar 100, the stakes 200, and even the guide assembly 300 in the tarpaulin rack according to the parameters of different types of truck compartments. The present application does not limit the specific sizes and specifications of each component in the tarpaulin rack.

[0053] It should also be noted that, although the tarpaulin rack in the present application is usually compatible with the truck compartment, it does not mean that the structure of the tarpaulin rack is unique. For example, the tarpaulin rack may only include a horizontal bar 100 and a vertical stake 200, and the horizontal bar 100 may be fixedly set on the fence of the compartment of the trolley, and the vertical stake 200 is set parallel to the side beam of the compartment of the trolley; or, the tarpaulin rack may also include a horizontal bar 100, a side bar and a vertical stake 200, and the horizontal bar 100 and the side bar are connected to form a closed frame structure, and the horizontal bar 100 and the side bar may be fixedly set on the fence of the compartment of the trolley, and the vertical stake 200 is parallel to the side beam of the compartment of the trolley. The present application does not limit the specific structure of the tarpaulin rack.

[0054] In addition, the fixing frame 310 and the mounting seat 320 in the guide assembly 300 are formed on the first contact surface 110 and the second contact surface 210 respectively, wherein the fixing frame 310 and the mounting seat 320 can be arranged on the crossbar 100 and the pile 200 in various ways. For example, the fixing frame 310 and the horizontal bar 100 are integrally formed, and the mounting seat 320 and the pile 200 are integrally formed; or the fixing frame 310 and the pile 200 are integrally formed, and the mounting seat 320 and the horizontal bar 100 are integrally formed; or, the fixing frame 310 and the horizontal bar 100 are detachably connected, and the mounting seat 320 and the pile 200 are detachably connected; or, the fixing frame 310 and the pile 200 are detachably connected, and the mounting seat 320 and the horizontal bar 100 are detachably connected; even, the fixing frame 310 and the horizontal bar 100 are integrally formed, and the mounting seat 320 and the pile 200 are detachably connected; or, the fixing frame 310 and the horizontal bar 100 are detachably connected, and the mounting seat 320 and the pile 200 are integrally formed, and the present application does not limit this.

[0055] It can be understood that the buffer space 311 formed in the fixed frame 310 mainly limits the relative displacement between the fixed frame 310 and the mounting seat 320 by cooperating with the guide member 330. In addition, the shape and structure of the buffer space 311 can be adjusted according to the guide member 330 of different structures. For example, when the guide member 330 is a roller, the buffer space 311 can be an arc-shaped rolling groove; when the guide member 330 is a slider, the buffer space 311 can be a rectangular slide groove matched with the slider; or, the guide member 330 can be a slider made of a material with a low friction coefficient (such as nylon, polyethylene, etc.), and the buffer space 311 can be a slide rail adapted to the shape of the slider, etc. In view of the fact that the guide member 330 and the buffer space 311 can be implemented by a variety of different structures, the present application does not limit the specific structure of the buffer space 311 and the guide member 330. The guide member can also be an optical axis. In addition, a sliding layer is provided on the inner wall of the fixed frame to facilitate the sliding of the guide member.

[0056] The tarpaulin frame with anti-deformation function provided in the present application can, through the arrangement of the above-mentioned structure, enable the horizontal bar 100 and the upright stake 200 of the tarpaulin frame to move relative to each other when the tarpaulin frame is impacted by external force, and the external force is consumed in the buffer space 311, thereby greatly reducing the stress that may be generated between the two, so as to avoid adverse deformation of the tarpaulin frame as much as possible, thereby ensuring the stability of the overall structure of the tarpaulin frame.

[0057] In some embodiments, reference Figure 2 and Figure 4As shown, the horizontal bar 100 has a horizontal section 120 and a vertical section 130, and a bending section 140 connected to the horizontal section 120 and the vertical section 130 respectively, and the first contact surface 110 is formed on the bottom surface of the vertical section 130. The horizontal bar 100 of this structure, through the arrangement of the bending section 140, enables the tarpaulin frame to move more smoothly along the contour of the tarpaulin frame when it cooperates with the tarpaulin cover 400 described below. In addition, the bending section 140 can disperse the stress generated on the vertical section 130 to a certain extent, which is conducive to improving the structural strength and stability of the horizontal bar 100, and the appearance of the horizontal bar 100 of this structure is more beautiful.

[0058] In a specific example, the fixing frame 310 and the vertical section 130 in the present application are integrally formed, and the mounting seat 320 and the stake 200 are integrally formed. This integral forming method is conducive to improving the connection strength between the fixing frame 310 and the horizontal bar 100, and between the mounting seat 320 and the stake 200, so that the relative movement process between the horizontal bar 100 and the stake 200 is more stable.

[0059] In some embodiments, the fixing frame 310 is provided with a fixing hole (not shown in the figure), and one of the first contact surface 110 and the second contact surface 210 is provided with an assembly hole (not shown in the figure); the mounting seat 320 is provided with a mounting hole (not shown in the figure), and the other of the first contact surface 110 and the second contact surface 210 is provided with a connection hole (not shown in the figure). In addition, the guide assembly 300 also includes a fastener (not shown in the figure), which can pass through the fixing hole to cooperate with the assembly hole, and pass through the mounting hole to cooperate with the connection hole, so as to respectively realize the detachable connection between the fixing frame 310 and the crossbar 100, and the mounting seat 320 and the stake 200. Optionally, the fixing hole, the assembly hole, the mounting hole and the connection hole can all be threaded holes, and the fastener can be a screw, a bolt or a stud that cooperates with the threaded hole, etc., and the present application does not limit the specific structure of the above-mentioned parts.

[0060] In this embodiment, the fixing holes, assembly holes, mounting holes, connecting holes and fasteners are provided to achieve a detachable connection between the fixing frame 310, the mounting seat 320, the cross bar 100 and the stakes 200. This detachable connection arrangement facilitates the later maintenance of the guide assembly 300 by the user, and also enables the tarpaulin rack to adapt to guide assemblies 300 of different specifications and sizes, which is beneficial to the user experience.

[0061] In another specific example, referring to Figure 5 and Figure 6As shown, the guide member 330 is a roller, and the roller includes a roller shaft 331 and a roller body 332. Both ends of the roller shaft 331 are fixedly connected to the side walls of the mounting groove 321. The roller body 332 is sleeved on the outer side of the roller shaft 331, and the edge of the roller body 332 has a pair of stoppers 333 extending along its radial direction, and the distance between the pair of stoppers 333 is not less than the width of the fixed frame 310. The setting of the stoppers 333 can limit the axial displacement of the guide member 330, prevent the guide member 330 and the mounting seat 320 from axially shaking relative to the fixed frame 310, thereby further facilitating the improvement of the stability of the guide assembly 300.

[0062] In some embodiments, continue to refer to Figure 5 and Figure 6 As shown, there are two rollers, which are respectively arranged on both sides of the center line of the pile 200. When there are multiple rollers, on the one hand, the relative movement between the fixing frame 310 and the mounting seat 320 can be smoother, and on the other hand, the relative displacement distance between the fixing frame 310 and the mounting seat 320 can be limited to a certain extent, thereby preventing the center line of the crossbar 100 from excessively deviating from the center line of the pile 200, so as to improve the stability and structural strength of the tarpaulin frame during deformation.

[0063] Furthermore, the ratio of the length of the fixing frame 310 to the width of the vertical section 130 is between 1.5 and 1. Although the present application does not specifically limit the size of each component in the guide assembly 300, in order to take into account both the structural stability and deformation limit of the tarpaulin rack, the buffer space 311 can meet the deformation requirements and structural stability of the tarpaulin rack by limiting the size ratio of the fixing frame 310 and the vertical section 130 of the crossbar 100. Among them, the width of the vertical section 130 and the length of the fixing frame 310 both refer to the distance along the length direction of the truck compartment.

[0064] In addition, since the present application does not limit the number of the horizontal bars 100 and the vertical stakes 200 in the tarpaulin frame, when the number of the horizontal bars 100 and the vertical stakes 200 is different, the number of the guide assembly 300 can also be configured in a variety of embodiments:

[0065] Implementation Method 1

[0066] There are two horizontal bars 100 and four upright posts 200 , and the four upright posts 200 correspond to the two horizontal bars 100 in pairs; there are two guide assemblies 300 , and the two guide assemblies 300 are respectively arranged on both sides of any horizontal bar 100 .

[0067] Implementation Method 2

[0068] Reference Figure 1As shown, there are two horizontal bars 100 and four upright posts 200 , and the four upright posts 200 correspond to the two horizontal bars 100 in pairs; there are four guide assemblies 300 , and the four guide assemblies 300 are respectively arranged on both sides of the two horizontal bars 100 .

[0069] Implementation Method 3

[0070] For some vehicles with longer carriages (such as 17.5m carriages, 13.6m carriages, 9.6m carriages, etc.), in addition to setting two cross bars 100 at the front and rear ends of the carriage, multiple cross bars 100 can be set at intervals between the front and rear cross bars 100 to further improve the overall structural strength and stability of the tarpaulin rack and the truck tarpaulin system. For example, for a 17.6m carriage, the number of cross bars 100 in the tarpaulin rack can be five, of which two cross bars 100 are respectively set at the front and rear ends of the carriage, and the other three cross bars 100 are evenly spaced between the front and rear cross bars 100. It should be noted that the bottom of the three middle cross bars 100 may be provided with stakes 200, or stakes 200 may not be set. Furthermore, when the piles 200 are arranged at the bottom of the three horizontal bars 100, a guide assembly 300 may be arranged between any horizontal bar 100 and the pile 200; of course, the guide assembly 200 may not be arranged between the three middle horizontal bars 100 and the pile 200, and the present application has no limitation on this.

[0071] It is understandable that when the number of guide assemblies 300 in the tarpaulin frame is different, the relative displacement limit between the horizontal bar 100 and the upright stake 200 is different. For example, in the above-mentioned embodiment 1, the relative displacement limit between the horizontal bar 100 and the upright stake 200 depends on the distance of the buffer space 311 in the fixing frame 310; in the above-mentioned embodiment 2, since there are two guide assemblies 300 on the same side of the tarpaulin frame, the relative displacement limit between the horizontal bar 100 and the upright stake 200 is twice that of the second embodiment.

[0072] In addition, in some other embodiments, the guide assembly 300 may further include a limiting member (not shown in the figure), wherein the limiting member may be a limiting pin, a limiting column, a limiting baffle, a limiting block, a limiting bolt, etc., which are arranged on the mounting seat. By setting the limiting member, the relative position of the fixing frame 310 and the mounting seat 320 in the guide assembly 300 can be fixed, which is conducive to improving the structural stability of the guide assembly 300, thereby avoiding to a certain extent the shaking of the tarpaulin frame due to the inability to relatively fix the fixing frame 310 and the mounting seat 320 during the driving of the truck.

[0073] Furthermore, the guide assembly 300 may also include a buffer member (not shown in the figure) disposed in the buffer space 311, and the buffer member can contact the guide member 330 during the movement of the guide member 330 in the buffer space 311. By setting the buffer member, the movement process of the guide member 330 can be buffered, and the guide member 330 can be prevented from generating an overload impact on the fixed frame 310 as much as possible, thereby facilitating the improvement of the stability of the guide assembly 300. The buffer member may be a buffer spring, a buffer gasket, an elastic plate, a buffer filler, etc., and the present application does not limit the specific type of the buffer member. In addition, the buffer member may be directly connected to the guide member 330 or may not be connected, and the present application does not limit the specific setting method of the buffer member.

[0074] In some embodiments, the stake 200 in the present application is a lifting column with a multi-stage telescopic section. The lifting column with a telescopic structure allows the height of the stake 200 to be flexibly adjusted, so that the tarpaulin rack can adapt to truck compartments of different specifications and sizes, thereby improving the applicability of the tarpaulin rack.

[0075] In addition, continue to refer to Figure 1 As shown, an embodiment of the present invention further provides a truck tarpaulin system, including a tarpaulin cover 400 and a tarpaulin frame as described above, the cross bar 100 is provided with a guide member 150, and the tarpaulin cover 400 is provided with a transmission member (not marked in the figure), and the transmission member and the guide member 150 cooperate to enable the tarpaulin cover 400 to move along the contour of the tarpaulin frame.

[0076] Among them, the guiding member 150 can be a chain, and the transmission member can be a sprocket, and the sliding connection between the tarpaulin cover 400 and the tarpaulin frame is achieved through the cooperation between the chain and the sprocket; or, the guiding member 150 can be a rack, and the transmission member can be a gear, and the sliding connection between the tarpaulin cover 400 and the tarpaulin frame is achieved through the cooperation between the gear and the rack.

[0077] It can be understood that the truck tarpaulin system provided in the present application may not be provided with a tarpaulin cover 400 in actual application, and the tarpaulin covering the outside of the tarpaulin frame can be raised and lowered only by the lifting function of the stakes 200 themselves; or, the truck tarpaulin system may further include a cloth rolling assembly (not shown in the figure) arranged on the outside of the tarpaulin frame, the cloth rolling assembly including a cloth rolling rod connected to the edge of the tarpaulin and a driving member connected to the cloth rolling rod; wherein the cloth rolling rod can rotate with the driving of the driving member, and can roll up the tarpaulin on the outside of the cloth rolling rod, thereby realizing the deployment and retraction of the tarpaulin on the outside of the tarpaulin frame.

[0078] In addition, refer to Figure 7 and Figure 8As shown, the embodiment of the present application also provides a new type of carriage, including a carriage body 500 and a truck tarpaulin system arranged on the carriage body 500, and the tarpaulin system includes a tarpaulin frame and a tarpaulin cover 400 slidably matched with the tarpaulin frame, and the tarpaulin frame includes a horizontal bar 100 and a stake 200 located below the horizontal bar 100, and a guide assembly 300 respectively connected to the horizontal bar 100 and the stake 200.

[0079] In this embodiment, the guide assembly 300 may further include a first guide group 340 disposed at the connection between the horizontal bar 100 and the upright stake 200, and the first guide group 340 has a first motion path, and in response to the deformation of the tarpaulin frame, the first guide group 340 can move along the first motion path to achieve relative motion between the horizontal bar 100 and the upright stake 200. The direction of the first motion path may be the same as the width direction of the body 500, or may be the same as the length direction of the body 500, and the present application does not limit the direction of the first motion path.

[0080] Specifically, refer to Figure 8 As shown, the first guide group 340 may include a first fixed portion 341 disposed on the horizontal bar 100 and a first sliding portion 342 slidably matched with the first fixed portion 341, and a first rotating portion 343 disposed below the first sliding portion 342. The first guide group 340 is rotatably connected to the pile 200 through the first rotating portion 343.

[0081] Among them, the first fixed part 341 can be a fixed guide rail, a fixed guide block, a guide tube, etc., the first sliding part 342 can be a sliding seat, a guide groove, a guide wheel, a ball, a roller, etc. that cooperate with the fixed guide rail and the fixed guide block respectively, and the first rotating part 343 can be a universal ball, a hinged seat, etc. The present application does not limit the specific structures of the first fixed part 341, the first sliding part 342 and the first rotating part 343.

[0082] It can be understood that the first fixed portion 341 cooperates with the first sliding portion 342 to achieve relative movement between the two, and the movement path formed by the first fixed portion 341 relative to the first sliding portion 342 forms a first movement path. The existence of the first moving wheel diameter enables the tarpaulin rack itself to reduce the horizontal stress that may be generated at the connection between the horizontal bar 100 and the stake 200 after the horizontal bar 100 or the stake 200 receives the deformation transmitted by the box body 500. In addition, the provision of the first rotating portion 343 enables a certain degree of relative rotation between the horizontal bar 100 and the stake 200, which is conducive to reducing the vertical or circumferential stress that may be generated at the connection between the two.

[0083] Regarding the specific structure of the first guide group 340, in addition to the above structure, it can also be implemented according to the following contents, specifically:

[0084] Reference Fig. 9 As shown, the first guide group 340 in the present invention may include a first fixing portion 341 and a first sliding portion 342 slidably matched with the first fixing portion 341. The first fixing portion 341 may be a fixing plate, and the first sliding portion 342 may be a sliding block.

[0085] In some embodiments, reference Fig.10 As shown, the guide assembly 300 may further include a second guide group 350, the horizontal bar 100, the first guide group 340, the second guide group 350 and the stake 200 are connected in sequence, and the second guide group 350 has a second movement path; the first movement path is parallel to the length direction or the width direction of the tarpaulin frame, and the second movement path is perpendicular to the first movement path; in response to the deformation of the tarpaulin frame, the first guide group 340 can move along the first movement path and / or the second guide group 350 can move along the second movement path to achieve relative movement between the horizontal bar 100 and the stake 200.

[0086] It should be noted that the second guide group 350 is arranged perpendicularly to the first guide group 340, so that the second motion path is perpendicular to the first motion path. In other words, when the first motion path is along the length direction of the tarpaulin frame, the second motion path is along the width direction of the tarpaulin frame; when the first motion path is along the width direction of the tarpaulin frame, the second motion path is along the length direction of the tarpaulin frame.

[0087] The arrangement of the first guide group 340 and the second guide group 350 can reduce the horizontal stress that may be generated by the tarpaulin frame to the greatest extent, thereby further improving and reducing the possible deformation of the tarpaulin frame, and further facilitating the improvement of the structural stability of the tarpaulin frame.

[0088] Specifically, in this embodiment, continue to refer to Fig.10 As shown, the second guide group 350 may include a second sliding portion 351 connected to the first rotating portion 343, and a second fixing portion 352 slidably matched with the second sliding portion 351. The first fixing portion 341 is connected to the horizontal bar 100, and the second fixing portion 352 is connected to the pile 200; the second sliding portion 351 and the second fixing portion 352 may be a slide block, a slide rail, etc., which is not limited in the present application.

[0089] In some embodiments, reference Fig.10 As shown, the first guide group 340 may further include a first stop portion 344 disposed at the end of the first sliding portion 342, and the second guide group 350 may further include a second stop portion 353 disposed at the end of the second sliding portion 351, and the first stop portion 344 and the second stop portion 353 can respectively cooperate with the first fixed portion 341 and the second fixed portion 352 to stop.

[0090] The setting of the first stop portion 344 and the second stop portion 353 can limit the travel of the first movement path and the second movement path, preventing the first fixed portion 341 and the second fixed portion 352 from slipping off the first sliding portion 342 and the second sliding portion 351 respectively, thereby ensuring the stability of the sliding process of the first guide group 340 and the second guide group 350.
