Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation technology, and in particular to an anti-dumping device. Background Art

[0002] At present, the photovoltaic industry is gradually expanding, and more and more new modules are being manufactured, including frameless photovoltaic modules. Frameless photovoltaic modules are more likely to break or break during transportation and stacking due to the lack of metal frame protection. According to the investigation, many frameless photovoltaic modules are damaged due to the collapse or deformation of the packaging.

[0003] In the prior art, frameless photovoltaic modules are generally stacked layer by layer, and the stacked frameless photovoltaic modules are then packaged as a whole to form a photovoltaic module package, which is shipped as an independent whole. As the size of a single photovoltaic module becomes larger and larger, the size of the photovoltaic module package is also getting larger and larger. After the frameless photovoltaic modules are delivered to the project site or the specific unloading destination, there is still a certain amount of time before the actual installation of the frameless photovoltaic modules. During this period, the photovoltaic module package at the storage site will often topple over due to bad project site conditions, weather conditions, unstable placement platform, etc., thereby causing great losses to the photovoltaic modules. Utility Model Content

[0004] The purpose of the present application is to provide an anti-dumping device to prevent the stored photovoltaic components from tipping over, thereby reducing losses.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] An anti-dumping device, used to prevent a photovoltaic module packaging body from dumping, comprising:

[0007] A base, the base being capable of being positioned relative to a photovoltaic module packaging body;

[0008] A first side stopper, wherein the bottom end of the first side stopper is fixedly connected to the base;

[0009] The second side stopper is connected to the first side stopper, and the first side stopper and the second side stopper are respectively used to block two adjacent sides of the photovoltaic component packaging body.

[0010] When the anti-dumping device provided by the utility model is used, when placing the photovoltaic module package, the bottom of the photovoltaic module package is pressed against the upper side of the base, the base and the photovoltaic module package are relatively positioned, and the first side block is abutted against one side of the photovoltaic module package, the second side block is abutted against the other side of the photovoltaic module package, and the first side block and the second side block are respectively abutted against the adjacent two sides of the photovoltaic module package. In this way, when the photovoltaic module dumps, the tilting torque will be transmitted to the first side block and / or the second side block, and the tilting torque will eventually be transmitted to the base and then restricted, that is, the first side block and / or the second side block can be used to prevent the stacked photovoltaic modules from further dumping, and then the photovoltaic modules can be prevented from dumping due to bad project site conditions, weather conditions, unstable placement platform, etc., thereby reducing losses.

[0011] In one implementation, a buffer is further provided on one side of the second side stopper adjacent to the photovoltaic module packaging body, and the buffer contacts the edges of the plurality of photovoltaic modules to prevent stress concentration and damage to the edges of the plurality of photovoltaic modules;

[0012] The buffer member includes a plurality of slots arranged in sequence, and the slots are used to accommodate the edges of the photovoltaic components. The slots can not only protect the edges of the photovoltaic components and prevent them from being damaged due to stress concentration, but also increase the friction between the photovoltaic components and the second side stopper, further preventing the photovoltaic components from tipping over.

[0013] In one implementation, the base includes a bottom plate, a portion of which can extend into the bottom of the photovoltaic module packaging body for positioning;

[0014] The bottom plate is fixedly connected to the first side stopper, or the base further includes a supporting structure fixedly connected to the bottom plate, and the supporting structure is fixedly connected to the first side stopper. The upper surface of the bottom plate is flat, and after contacting the bottom of the photovoltaic module package, the stability of the photovoltaic module package is ensured, and the photovoltaic module package will not shake or tilt.

[0015] In one implementation, the base includes a support structure, and at least one positioning rod extends from one side of the support structure. The positioning rod can extend into a tray of a photovoltaic module packaging body for positioning.

[0016] In one implementation, the support structure includes a plurality of fixedly connected support rods or support plates; by adopting this technical solution, the positioning rod can be extended into the gap between the upper and lower plates of the tray after the photovoltaic module package is placed, eliminating the need to align the base during the placement of the photovoltaic module package, thereby facilitating operation.

[0017] The cross section of the support rod is square, which increases the contact area between the support rod and the first side stopper and makes it easier to assemble and fix the two.

[0018] In one implementation, the first side stopper includes a stopper surface, and the stopper surface is used to abut against the front or back of the photovoltaic module. The first side stopper uses the stopper surface to abut against the front or back of the photovoltaic module to avoid the contact area between the first side stopper and the photovoltaic module being too small, which may cause the photovoltaic module to crack or break due to stress concentration.

[0019] In one implementation, the first side stopper includes at least two vertical stopper bars, the bottom ends of the vertical stopper bars are connected to the base, and the sides of the plurality of vertical stopper bars that are used to contact the front or back side of the photovoltaic module together form a stopper surface;

[0020] The vertical blocking rod is arranged perpendicular to the base for easy connection; and / or, an intermediate blocking rod is also connected between two adjacent vertical blocking rods, and the side of the intermediate blocking rod used for contacting the front or back of the photovoltaic component is in the same plane as the blocking surface. The cross-section of the vertical blocking rod and / or the intermediate blocking rod is square. With the support of the intermediate blocking rod, the vertical blocking rod is not prone to shaking or dislocation, making the first side blocking member more stable when resisting the photovoltaic component packaging body.

[0021] In one implementation, it also includes a sliding rod fixedly connected to the first side stopper, and the side of the sliding rod used to contact the front or back of the photovoltaic module is in the same plane as the abutment surface. The second side stopper slides with the sliding rod, and the second side stopper can slide along the sliding rod to approach or move away from the first side stopper. The position of the second side stopper can be adjusted according to the position of the photovoltaic module package body. Compared with constantly adjusting the photovoltaic module package body, the operation is more convenient.

[0022] In one implementation, the second side stopper is provided with an insertion hole, and the slide bar can be inserted into the insertion hole, which has a simple structure and is convenient for assembling and adjusting the position of the second side stopper;

[0023] A limiting portion is provided on the slide bar, and the second side stopper can slide along the slide bar in a direction away from the first side stopper until it abuts against the limiting portion, so that the limiting portion can block the second side stopper to prevent the second side stopper from slipping off the slide bar.

[0024] The side of the slide bar used for contacting the front or back side of the photovoltaic module is in the same plane as the abutment surface of the first side stopper to prevent the slide bar from tilting, and the second side stopper slides down along the slide bar.

[0025] In one implementation, the slide bar can be moved along the height direction of the first side stopper to a preset position and then fixedly connected to the first side stopper;

[0026] The first side block is provided with a slide groove, and the slide rod is fixedly connected to the first side block by a bolt passing through the slide groove. The length of the slide groove can be set along the height direction of the first side block, and the height of the bolt and the slide rod can be adjusted by moving the position of the bolt in the slide groove. The structure is simple and easy to operate.

[0027] In one implementation, the second side baffle includes a transverse baffle and / or at least one transverse baffle bar. The contact area between the transverse baffle and the photovoltaic module package is relatively large. The number of transverse baffles may be one or more. The cross section of the transverse baffle bar may be square, so that the contact area between the transverse baffle bar and the photovoltaic module package is larger, thereby preventing stress concentration and damage to the edges of multiple photovoltaic modules.

[0028] The transverse baffle and / or the transverse baffle rod are arranged perpendicularly to the abutment surface of the first side baffle to ensure that the first side baffle and the second side baffle can respectively abut against the two side surfaces of the photovoltaic component packaging body.

[0029] In one implementation, the second side stopper is vertically arranged to the abutting surface of the first side stopper, so that the second side stopper and the abutting surface are respectively attached to and abut against two side surfaces of the photovoltaic module package, making the photovoltaic module package more stable.

[0030] In one implementation, the bottom end of the first side stopper is fixedly connected to the base by plugging, snapping, threading, interference fit and / or welding, which is convenient for processing and manufacturing; or,

And / or,

[0033] The anti-dumping device also includes an oblique support rod, one end of which is fixedly connected to the first side blocker, and the other end is fixedly connected to the base.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] The anti-dumping device provided in the embodiment of the present application is used to cooperate with the photovoltaic module packaging body 7, so as to use the anti-dumping device to resist the two adjacent sides of the photovoltaic module packaging body 7 to prevent the photovoltaic module packaging body 7 from tipping over. The photovoltaic module packaging body 7 includes a tray and a plurality of photovoltaic modules stacked on the tray, wherein each photovoltaic module is placed in a vertical direction, and a plurality of photovoltaic modules are stacked in sequence in a horizontal direction. The photovoltaic module packaging body 7 may also include a packaging body covering the tray and the plurality of photovoltaic modules.

[0049] See also Figure 1 and Figure 4 The anti-dumping device provided in the embodiment of the present application includes a base 1, a first side stopper 2 and a second side stopper 3. The base 1 can be positioned relative to the photovoltaic module package 7, that is, after the base 1 is placed, the base 1 and the photovoltaic module package 7 are relatively fixed, and the two can no longer move relative to each other, so as to ensure that the first side stopper 2 and the second side stopper 3 can abut against the adjacent two sides of the photovoltaic module package 7. Specifically, a part of the base 1 can be located at the lower side of the photovoltaic module package 7. When the photovoltaic module package 7 is placed, the photovoltaic module package 7 is pressed on the upper side of the part of the base 1, that is, the tray of the photovoltaic module package 7 is pressed on the upper side of the part of the base 1, and the pressure of the photovoltaic module package 7 is used to prevent the base 1 from moving, so that the base 1 and the photovoltaic module package 7 are positioned relative to each other.

[0050] The bottom end of the first side stopper 2 is fixedly connected to the base 1, and the first side stopper 2 extends from the bottom end to the top end. When the anti-dumping device is in use, the first side stopper 2 abuts against one side of the photovoltaic module package 7, that is, the first side stopper 2 abuts against one side of the photovoltaic module package 7. Preferably, the first side stopper 2 abuts against the photovoltaic module at the edge of the photovoltaic module package 7, and the first side stopper 2 abuts against the front or back of the photovoltaic module at the edge.

[0051] The second side stopper 3 is connected to the first side stopper 2, and the first side stopper 2 and the second side stopper 3 are respectively used to block the two adjacent sides of the photovoltaic module package 7. The second side stopper 3 can abut against the other side of the photovoltaic module package 7, and the other side of the photovoltaic module package 7 includes the edges of multiple photovoltaic modules, that is, the second side stopper 3 abuts against the edges of multiple photovoltaic modules.

[0052] When the anti-dumping device provided by the utility model is used, when placing the photovoltaic module package 7, the bottom of the photovoltaic module package 7 is pressed against the upper side of the base 1, the base 1 and the photovoltaic module package 7 are relatively positioned, and the first side stopper 2 is abutted against one side of the photovoltaic module package 7, and the second side stopper 3 is abutted against the other side of the photovoltaic module package 7, and the first side stopper 2 and the second side stopper 3 are respectively abutted against the adjacent two sides of the photovoltaic module package 7. In this way, when the photovoltaic module dumps, the tilting moment will be transmitted to the first side stopper 2 and / or the second side stopper 3, and finally the tilting moment will be transmitted to the base 1 and then restrained, that is, the first side stopper 2 and / or the second side stopper 3 can be used to prevent the stacked photovoltaic modules from further dumping, and then the photovoltaic modules can be prevented from dumping due to bad project site conditions, weather conditions, unstable placement platform, etc., thereby reducing losses.

[0053] In a specific embodiment, two anti-tipping devices can be used in conjunction with diagonal positions of the same photovoltaic module package 7, so that the photovoltaic module package 7 is abutted against side stoppers on all four sides to further prevent the photovoltaic module package 7 from tipping over.

[0054] like Figure 2 As shown, since the second side stopper 3 abuts against the side of the photovoltaic module package 7 having multiple photovoltaic module edges, the photovoltaic module edges are easily damaged by force, and therefore a buffer member 4 is further provided on the side of the second side stopper 3 adjacent to the photovoltaic module package 7. The buffer member 4 contacts the multiple photovoltaic module edges to prevent stress concentration and damage to the multiple photovoltaic module edges.

[0055] Since the junction box of the photovoltaic module protrudes from the front or back of the photovoltaic module, in order to prevent the junction box from hitting the adjacent photovoltaic module, there is generally a gap between the adjacent photovoltaic modules, that is, after multiple photovoltaic modules are stacked, there is a gap between the adjacent photovoltaic modules. In view of the above situation, the buffer 4 can include a plurality of slots arranged in sequence, and the slots are used to accommodate the edges of the photovoltaic modules. After the second side stopper 3 abuts against one side of the photovoltaic module packaging body 7, the edges of the multiple photovoltaic modules extend into the multiple slots of the buffer 4 respectively. The slots can not only protect the edges of the photovoltaic modules and prevent them from being damaged due to stress concentration, but also increase the friction between the photovoltaic modules and the second side stopper 3, further preventing the photovoltaic modules from tipping over.

[0056] The material of the buffer member 4 may be EVA plastic (Ethylene Vinyl Acetate Copolymer). Of course, the buffer member 4 may also be made of other materials such as rubber and silicone.

[0057] The buffer member 4 and the second side stopper 3 can be fixed by bonding, clamping, screw connection or the like.

[0058] like Figure 1 and Figure 4 As shown, the base 1 may include a bottom plate 1a, and a portion of the bottom plate 1a can extend into the bottom of the photovoltaic module package 7 for positioning. Specifically, when placing the photovoltaic module package 7, the bottom of the photovoltaic module package 7 is pressed against the upper side of the portion of the bottom plate 1a, and the pressure and friction of the photovoltaic module package 7 prevent the bottom plate 1a from moving, thereby ensuring the relative positioning of the bottom plate 1a and the photovoltaic module package 7. The upper surface of the bottom plate 1a is flat, and after contacting the bottom of the photovoltaic module package 7, the stability of the photovoltaic module package 7 is ensured, and the photovoltaic module package 7 will not be shaken or tilted.

[0059] In the above embodiment, the bottom plate 1a can be fixedly connected to the first side stopper 2, that is, the bottom plate 1a is directly fixedly connected to the first side stopper 2, which simplifies the structure. Alternatively, the base 1 also includes a support structure 1b fixedly connected to the bottom plate 1a, and the support structure 1b is fixedly connected to the first side stopper 2, that is, the bottom of the support structure 1b is fixedly connected to the bottom plate 1a, and the top of the support structure 1b is fixedly connected to the first side stopper 2. In this way, the support structure 1b is fixedly connected to the first side stopper 2, which is more convenient for assembly, and the support structure 1b is against the bottom side of the photovoltaic module packaging body 7, which can realize the positioning of the photovoltaic module packaging body 7.

[0060] In the above embodiment, the support structure 1b and the bottom plate 1a can be fixedly connected by welding, integral molding, threaded connection, clamping or interference fit, etc. The first side stopper 2 and the support structure 1b or the first side stopper 2 and the bottom plate 1a can also be fixedly connected by plugging, clamping, threaded connection, interference fit and / or welding, which is convenient for processing and manufacturing.

[0061] like Figure 6 As shown, the base 1 includes a support structure 1b, and at least one positioning rod extends from one side of the support structure 1b. The positioning rod can be inserted into the tray of the photovoltaic module package 7 for positioning. The positioning rod can be inserted into the gap between the upper and lower plates of the tray, and the top of the positioning rod can be against the upper plate of the tray, so as to achieve relative positioning of the positioning rod and the tray. With this technical solution, the positioning rod can be inserted into the gap between the upper and lower plates of the tray after the photovoltaic module package 7 is placed, and it is not necessary to align with the base 1 during the process of placing the photovoltaic module package 7, which is convenient for operation.

[0062] In the above embodiment, the support structure 1 b and the first side stopper 2 may also be fixedly connected by welding, integral molding, threaded connection, snap connection or interference fit.

[0063] like Figure 1As shown, the support structure 1b includes a plurality of fixedly connected support rods or support plates. The support rods or support plates can be fixedly connected by welding, screw connection, clamping or interference fit. The number of support rods or support plates can be two, three, four, five or more, and the support structure 1b can be a V-shaped frame, a triangular frame, a square frame or a frame of other shapes, or the plurality of support plates of the support structure 1b can be arranged in parallel or arranged along an intersection.

[0064] The cross section of the support rod can be square, so that the top surface of the support rod is fixedly connected to the first side block 2, increasing the contact area between the support rod and the first side block 2, making it easier to assemble and fix the two. In addition, the bottom surface of the support rod is in contact with the bottom plate 1a or the ground, ensuring the stability of the support structure 1b. Of course, solutions such as triangular or circular cross sections of the support rod are also within the protection scope of this application.

[0065] The first side stopper 2 includes a stopper surface, which is used to abut against the front or back of the photovoltaic module. During use, the side of the first side stopper 2 close to the photovoltaic module packaging body 7 forms a stopper surface, and the first side stopper 2 uses the stopper surface to abut against the front or back of the photovoltaic module to avoid the contact area between the first side stopper and the photovoltaic module being too small, resulting in hidden cracks or breakage of the photovoltaic module due to stress concentration.

[0066] The first side block 2 includes at least two vertical blocks 2a, and the bottom ends of the vertical blocks 2a are connected to the base 1. In this embodiment, the vertical blocks 2a and the base 1 can be fixedly connected by welding, threaded connection, snap-fit ​​or interference fit. The side of the multiple vertical blocks that are used to contact the front or back of the photovoltaic module together form the abutment surface. During the use of the anti-dumping device, the vertical blocks 2a can be arranged along the vertical direction or inclined relative to the vertical direction. The number of vertical blocks 2a can be two, three, four or more. The multiple vertical blocks 2a can be arranged in parallel or intersectingly, and it is only necessary to ensure that the vertical blocks 2a can abut against the side of the photovoltaic module packaging body 7.

[0067] Exemplarily, the first side stopper 2 includes a plurality of vertical stopper rods 2a extending in the vertical direction; or, the first side stopper 2 includes two intersecting vertical stopper rods 2a, the top ends of the plurality of vertical stopper rods 2a intersect and are fixedly connected, and the bottom ends of the two vertical stopper rods 2a are fixedly connected to the base 1.

[0068] Furthermore, the vertical blocking rod 2a is vertically arranged with the base 1 for easy connection. Of course, the angle between the vertical blocking rod 2a and the base 1 is an obtuse angle or an acute angle, which is also within the protection scope of the present application.

[0069] In order to improve the stability of the first side block 2, an intermediate block 2b is connected between two adjacent vertical block rods 2a, and the side of the intermediate block rod 2b that is used to contact the front or back of the photovoltaic module is in the same plane as the abutment surface of the first side block, and one end of the intermediate block rod 2b is fixedly connected to one vertical block rod 2a and the other end is fixedly connected to another vertical block rod 2a. With such a configuration, with the support of the intermediate block rod 2b, the vertical block rod 2a is not prone to shaking and misalignment, making the first side block 2 more stable when abutting the photovoltaic module packaging body 7. The vertical block rod 2a and the intermediate block rod 2b can be fixedly connected by welding, threaded connection, clamping or interference fit.

[0070] The cross section of the vertical bar 2a and / or the middle bar 2b is square, so that the contact area between the vertical bar 2a and / or the middle bar 2b and the photovoltaic module packaging body 7 is larger, avoiding stress concentration on the surface of the photovoltaic module and reducing the risk of hidden cracks or breakage of the photovoltaic module. Of course, the vertical bar 2a and / or the middle bar 2b having a cross section of a circular, elliptical, triangular or other shape is also within the protection scope of this application.

[0071] like Figure 4 and Figure 5 As shown, in order to facilitate the installation of the second side stopper 3, the anti-dumping device also includes a slide bar 5 fixedly connected to the first side stopper 2, the second side stopper 3 and the slide bar 5 are slidably matched, and the second side stopper 3 can slide along the slide bar 5 to approach or move away from the first side stopper 2. The slide bar 5 is fixedly connected to the vertical stopper 2a, and the slide bar 5 and the vertical stopper 2a can be fixedly connected by welding, screw connection, clamping or interference fit. During the placement of the photovoltaic module package 7, the first side stopper 2 is aligned with its side surface. After the photovoltaic module package 7 is placed, the photovoltaic module package 7 is pressed on the upper side of the base 1 and the first side stopper 2 is against one side of the photovoltaic module package 7, and then the second side stopper 3 is slid along the slide bar 5 until the second side stopper 3 is against the other side of the photovoltaic module package 7. In this way, the position of the second side stopper 3 can be adjusted according to the position of the photovoltaic module package 7, and the operation is more convenient than constantly adjusting the photovoltaic module package 7.

[0072] In the above embodiment, the second side stopper 3 is provided with an insertion hole, and the slide bar 5 can be inserted into the insertion hole. Specifically, after the slide bar 5 is inserted into the insertion hole of the second side stopper 3, the second side stopper 3 can slide along the slide bar 5 to abut against the other side of the photovoltaic module package 7. The cross section of the slide bar 5 can be square, triangular, oval, etc., and the shape of the insertion hole is the same as the cross-sectional shape of the slide bar 5, so that the second side stopper 3 can be prevented from rotating around the slide bar 5. Of course, a slide rail can also be provided on the slide bar 5, and the second side stopper 3 moves along the slide rail to abut against and fix against the other side of the photovoltaic module package 7, and the slide rail can be a T-slot or other rails.

[0073] Among them, the side of the slide bar 5 used for contacting the front or back of the photovoltaic component is in the same plane as the abutment surface of the first side stopper, thereby increasing the contact area between the slide bar 5 and the front or back of the photovoltaic component, making the photovoltaic component more stable and less likely to tilt.

[0074] In addition, a limiting portion is provided on the slide bar 5, and the second side stopper 3 can slide along the slide bar 5 in a direction away from the first side stopper 2 until it abuts against the limiting portion. In this way, the limiting portion can block the second side stopper 3 to prevent the second side stopper 3 from slipping off the slide bar 5. Specifically, the limiting portion can be a screw fixedly connected to the slide bar 5, or a plugging rod plugged into the slide bar 5, etc.

[0075] In order to adapt to photovoltaic module packaging bodies 7 of different sizes, the slide bar 5 can be moved to a preset position along the height direction of the first side stopper 2 and then fixedly connected to the first side stopper 2. In this way, the slide bar 5 can be moved along the height of the first side stopper 2 according to the height of the photovoltaic module packaging body 7, so that the slide bar 5 and the second side stopper 3 can be moved to a suitable height to adapt to photovoltaic module packaging bodies 7 of different heights.

[0076] like Figure 3 As shown, the first side block 2 may be provided with a slide groove 2a1, and the slide bar 5 is fixedly connected to the first side block 2 by a bolt passing through the slide groove 2a1. The length of the slide groove 2a1 may be set along the height direction of the first side block 2, and the height of the bolt and the slide bar 5 may be adjusted by moving the position of the bolt in the slide groove 2a1, which has a simple structure and is easy to operate. Alternatively, the first side block 2 may also be provided with a plurality of bolt holes, which are arranged in sequence along the height direction of the first side block 2, and the bolts and the slide bar 5 are fixedly connected with different bolt holes, which can also adjust the height of the bolts and the slide bar 5.

[0077] The second side stopper 3 may include a cross baffle and / or at least one cross baffle bar, that is, the second side stopper 3 may include a cross baffle and may include a cross baffle bar; when the second side stopper 3 includes a cross baffle bar, in view of the small contact area between the cross baffle bar and the photovoltaic module package 7, the number of the cross baffle bars is preferably two or more. The cross baffle plate has a large contact area with the photovoltaic module package 7, and the number of the cross baffle plates may be one or more. The cross baffle bar may have a square cross section so that the cross baffle bar has a larger contact area with the photovoltaic module package 7, thereby preventing stress concentration and damage to the edges of multiple photovoltaic modules.

[0078] The cross baffle and / or cross baffle rod are arranged perpendicularly to the abutting surface of the first side baffle to ensure that the first side baffle 2 and the second side baffle 3 can respectively abut against the two side surfaces of the photovoltaic module package 7. Of course, the angle between the cross baffle and / or cross baffle rod and the first side baffle 2 can be slightly greater than 90° or slightly less than 90° to adapt to photovoltaic module packages 7 of different sizes and shapes.

[0079] In another embodiment, the second side stopper 3 is vertically arranged to the abutting surface of the first side stopper, so that the second side stopper and the abutting surface are respectively attached to and abut against two side surfaces of the photovoltaic module package 7, making the photovoltaic module package 7 more stable.

[0080] The first side block 2 and the second side block 3 can be connected by plugging, snapping, threading, interference fit and / or welding, which simplifies the structure and facilitates processing and manufacturing. When the first side block 2 and the second side block 3 are relatively fixed, the first side block 2 and the second side block 3 can be welded, threaded or interference fit; when the first side block 2 and the second side block 3 need to slide relative to each other, the first side block 2 and the second side block 3 can be plugged or snapped, which can be set according to actual conditions.

[0081] like Figure 6 As shown, an elastic member 1c is fixedly provided on the base 1. When the base 1 extends into the gap between the upper and lower plates of the tray, the top end of the elastic member 1c abuts against the upper plate of the tray, and the bottom end of the elastic member 1c is fixed to the base 1. The elastic action of the elastic member 1c enables the base 1 and the tray to be relatively positioned to prevent the base 1 from being offset or misaligned.

[0082] The elastic member 1c may include a spring and / or an elastic pad, which has low cost and simple structure.

[0083] The anti-dumping device further comprises an oblique support rod 6, one end of which is fixedly connected to the first side block 2, and the other end of which is fixedly connected to the base 1. Specifically, one end of the oblique support rod 6 is fixedly connected to the vertical block rod 2a, and the other end of the oblique support rod 6 is fixedly connected to the base 1. The support function of the oblique support rod 6 can prevent the vertical block rod 2a from tilting or tipping, thereby improving the stability of the anti-dumping device. The oblique support rod 6 and the vertical block rod 2a and / or the base 1 can be welded, clamped, connected with screws, or interference fit.

[0084] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0085] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
