Description

Technical Field

[0001] The utility model relates to the technical field of mounting accessories, in particular to a frame pressing block. Background Art

[0002] Photovoltaic modules are often connected by using pressure blocks. There are some special-shaped pressure blocks in the prior art. For example, the patent document with application number 202021588295.6 discloses a pressure block for installing a steel frame module, including: a connecting plate, a support plate, a pressure plate, and a side. The support plates are symmetrically arranged on both sides of the connecting plate, and the angle between the support plate and the connecting plate is 100-160°. The pressure plate is horizontally and symmetrically arranged on one side of the support plate connected to the connecting plate. In the actual installation of such a pressure block as above, the contact surface between the pressure plate and the frame of the photovoltaic module will fit before the pre-tightening force is applied, but when the pre-tightening force is applied, the pressure plate will deform with the support plate, and then the pressure plate will warp, and finally the actual contact area between the pressure plate and the frame of the photovoltaic module will become smaller. Although the increased pre-tightening force will increase the friction, the reduction in the actual contact area also causes the frame to deform and become unstable. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] The specific embodiment of the utility model provides a frame pressing block, combined with the attached Figure 1 - Attachment Figure 3 As shown, it mainly includes a mounting plate 1 and a fastening plate 2;

[0027] The mounting plate 1 is provided with a mounting hole 4, and the mounting hole 4 is used to pass a bolt;

[0028] One end of the abutting plate 2 is connected to the mounting plate 1, and the other end of the abutting plate 2 extends in a direction away from the mounting plate 1. Specifically, the lower end surface of the abutting plate 2 is designed as an inclined surface 3, and the inclined surface 3 is inclined downward from the mounting plate 1 to the direction away from the mounting plate 1. Figure 1 As shown in the middle angle α; the above structure is adopted so that when the frame pressing block provided by the present application applies a pre-tightening force to the mounting plate 1 through bolts during actual installation, the frame pressing block will be deformed, and the contact surface of the inclined surface 3 with the component frame will gradually increase during deformation until the inclined surface 3 is completely fitted with the component frame, so that the actual contact surface is larger after pre-tightening, and the component frame is evenly stressed, thereby avoiding the problem of deformation and instability of the component frame and reducing the risk of the component falling out of the frame.

[0029] In a specific embodiment of the present application, as shown in the attached Figure 1 As shown in , based on the above embodiment, the angle between the inclined surface 3 and the horizontal plane is α, 0°<α≤20°, specifically α=5°, 10°, 15°, etc. The design of this angle can adapt to different materials and meet the requirements of bolt installation preload with different fastening performances.

[0030] In another embodiment of the present application, it further includes a first limiting portion 5. The first limiting portion 5 is arranged on the inclined surface 3 and can extend into a reserved hole 6 of the component frame.

[0031] Specifically, this first limiting portion 5 can be a convex block structure arranged obliquely. The convex block structure inclines downward towards the lower part of the mounting plate 1. This inclined arrangement can prevent the component frame from disengaging after the first limiting portion 5 extends into the reserved hole 6. When there is a relative displacement between the component frame and the frame pressing block, the first limiting portion 5 will abut against the side wall of the reserved hole 6, and at this time, the risk of the component frame being out of the frame can be further reduced. The first limiting portion 5 can also be designed as a protruding columnar body, a块状 body, etc. As long as this first limiting portion 5 can play a limiting role when the component frame and the frame pressing block translate relative to each other.

[0032] Specifically, the first limiting portion 5 can be formed by stamping the pressing plate 2. The stamping forming method is simple in processing and makes the first limiting portion 5 and the pressing plate 2 an integral formed structure.

[0033] In another embodiment of the present application, at least one corner of the end of the pressing plate 2 away from the mounting plate 1 can be designed as a rounded corner. This design of the rounded corner facilitates rotation during installation.

[0034] In another embodiment of the present application, it further includes a connecting plate 7. One side of the connecting plate 7 is smoothly connected to the mounting plate 1, and the other side is smoothly connected to the pressing plate 2, making the frame pressing block form a roughly "ji" shape. The connecting plate 7 is an arc-shaped plate, and the convexity of this arc-shaped plate faces the lower part of the mounting plate 1. Such a connecting plate 7 can make the frame pressing block deform smoothly during the fastening operation. Specifically, the width range of the frame pressing block is 30 mm to 50 mm, the length range is 50 mm to 80 mm, and the thickness range is 1.5 mm to 3 mm. For example, the specific dimensions of the frame pressing block can be a width of 40 mm, a length of 65 mm, and a thickness of 2 mm; the specific dimensions of the frame pressing block can also be a width of 35 mm, a length of 70 mm, and a thickness of 2.5 mm. The specific dimensions of the frame pressing block can be adaptively designed according to actual requirements and the materials used, etc.

[0035] In another embodiment of the present application, on the basis of any of the above embodiments, a second limiting portion 8 for restricting the rotation of the bolt is further designed. The second limiting portion 8 is arranged on the mounting plate 1 and close to the mounting hole 4. Through the limiting action of the second limiting portion 8, the bolt is kept stationary and is fastened by a nut at the bottom.

[0036] Specifically, this second limiting portion 8 can adopt a limiting convex block structure. There are at least two limiting convex blocks and they are evenly arranged on the periphery of the mounting hole 4. In a specific embodiment of the present application, there are two limiting convex blocks and they are oppositely arranged on both sides of the mounting hole 4. The limiting convex blocks can be formed by stamping the mounting plate 1, and the mounting hole 4 is formed simultaneously during stamping.

[0037] In another embodiment of the present application, there are two abutting plates 2 , which are arranged on both sides of the mounting plate 1 , and the abutting plates 2 on both sides abut against the frames of two photovoltaic modules respectively.

[0038] The specific installation method of the frame pressing block is as follows:

[0039] Combined with Figure 5 As shown, the frame pressing block and the bolts are manually placed between the two frame assemblies at the same time. At this time, one frame assembly is fixed and the other frame assembly is movable (the left frame assembly is fixed and the right frame assembly is movable). Then the position is manually adjusted and the frame pressing block is rotated until the clamping plate 2 faces the two frame assemblies, so that the frame pressing block and the left frame assembly are at the specified position. The frame pressing block is then clamped by a mechanical claw to keep it stationary, and the right frame assembly is pushed mechanically or manually to the bottom of the frame pressing block. Finally, the bolts are tightened by the nuts at the bottom to complete the installation of the photovoltaic module.
