The technical solution has the beneficial effect of stable installation.

[0004] Although the above-mentioned utility model patent can use the pressing block to install and fix the photovoltaic panel, it needs to rely on bolts to complete the fixation, with a complex structure and a cumbersome installation process. Therefore, there is an urgent need in the field for a misalignment-proof quick-installation middle pressing block to solve the problems existing in the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a misalignment-proof quick-installation middle pressing block to solve the above-mentioned deficiencies in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A misalignment-proof quick-installation middle pressing block, which includes two mutually adjacent top plates. The gap between the two top plates is the installation and fitting gap. A first pressing plate extending downward is fixed at one end of one of the top plates away from the installation and fitting gap, and a second pressing plate extending downward is fixed at one end of the other top plate away from the installation and fitting gap. A pressing side plate is fixed at each of the opposite ends of the top plates avoiding the positions where the first pressing plate and the second pressing plate are located. A limiting piece is fixed on the side wall of the first pressing plate away from the second pressing plate, and a limiting piece is fixed on the side wall of the second pressing plate away from the first pressing plate. The free end of the limiting piece extends obliquely upward.

[0007] The pressing side plate includes a first extension plate and a second extension plate connected end to end. The first extension plate is connected and fixed to the top plate, and the plane of the first extension plate is inclined downward relative to the plane of the top plate. The plane of the second extension plate is inclined upward relative to the plane of the first extension plate.

[0008] The bottom end of the first pressing plate is fixedly connected to the bottom end of the second pressing plate.

[0009] As a preferred solution, activity grooves are provided in the areas of the first pressing plate and the second pressing plate close to the limiting piece, and the opening area of the activity groove is larger than the surface area of the limiting piece on the side close to the activity groove.

[0010] As a preferred solution, the first pressing plate includes a first L-shaped plate connected and fixed to the top plate, and a third L-shaped plate is connected and fixed to the end of the first L-shaped plate away from the top plate; the second pressing plate includes a second L-shaped plate connected and fixed to the top plate, and a fourth L-shaped plate is connected and fixed to the end of the second L-shaped plate away from the top plate; the bottom ends of the third L-shaped plate and the fourth L-shaped plate are fixedly connected; the activity groove and the limiting piece are located on the third L-shaped plate and the fourth L-shaped plate.

[0011] As a preferred solution, the included angle between the plane of the first extension plate and the plane of the top plate is 10° - 15°, and the included angle between the plane of the second extension plate and the plane of the first extension plate is 180° - 185°.

[0012] As a preferred solution, the included angle between the plane of the first extension plate and the plane of the top plate is 13°, and the included angle between the plane of the second extension plate and the plane of the first extension plate is 183°.

[0013] As a preferred solution, reinforcing ribs are provided on the second extension plate.

[0014] As a preferred solution, the bottom ends of the third L-shaped plate and the fourth L-shaped plate are integrally formed and fixedly connected.

[0015] As a preferred solution, the pressing block is integrally formed.

[0016] With the above technical solution, multiple photovoltaic panels are installed on C-shaped steel. Compression blocks are installed at the gaps between adjacent photovoltaic panels. The compression blocks are forced towards the inside of the C-shaped steel. The limiting piece is squeezed by the C-shaped steel, and the limiting piece, the first pressing plate, and the second pressing plate generate elastic deformation towards the middle of the compression block. The bottom of the pressing side plate abuts against the top surface of the photovoltaic panel frame, and when the compression block is further forced, the pressing side plate generates elastic deformation. Continue to apply force to the compression block until the limiting piece is embedded in the C-shaped steel groove. At this time, the limiting piece and the pressing side plate complete the clamping and fixing of the C-shaped steel and two adjacent photovoltaic panels, and have a tendency to recover deformation, resulting in a good fixing effect on the photovoltaic panel, and having an elastic adaptation function to cope with external impact forces, extending the service life of the C-shaped steel, photovoltaic panel, and compression block, and reducing maintenance costs. During the above installation process, the clearance of the installation fit gap is not 0 in the initial state. After the installation is completed, due to the C-shaped steel squeezing the first pressing plate and the second pressing plate to approach each other, the clearance of the installation fit gap becomes 0. This solution uses the method of reserving an installation fit gap at the top of the compression block to replace the technical solution of truncating at the bottom junction of the first pressing plate and the second pressing plate in the prior art. Compared with the prior art solution, in the prior art, the junction with the second pressing plate needs to be in mutual contact to maintain the rigidity of the lower half of the compression block, so that the fixing stability of the photovoltaic panel is good. However, during the installation process, as Figure 8 shown, due to the squeezing effect, the probability of dislocation at the junction of the first pressing plate and the second pressing plate is high. And once dislocation occurs, due to the action of friction, it is difficult for the junction of the first pressing plate and the second pressing plate to rebound to the initial state, and the junction of the first pressing plate and the second pressing plate cannot be in mutual contact. At this time, tools need to be used to manually reset to the initial state, and the installation process is cumbersome. This solution designs an installation fit gap as the deformation space during the installation process, which can ensure the lateral support force at the bottom of the compression block while avoiding the occurrence of dislocation phenomena, resulting in high installation efficiency.

[0017] Beneficial effects:

[0018] 1. This solution uses C-shaped steel as the supporting frame for the photovoltaic panel, and designs a compression block that can closely cooperate with the C-shaped steel, enabling the convenient and rapid assembly of the C-shaped steel, photovoltaic panel, and compression block in a pressing-in manner without the need for bolts, with low cost and high installation efficiency;

[0019] 2. This solution uses the method of reserving an installation fit gap at the top of the compression block to replace the technical solution of truncating at the bottom junction of the first pressing plate and the second pressing plate in the prior art, making the installation convenient and improving the installation efficiency; designing the installation fit gap as the deformation space during the installation process can ensure the lateral support force at the bottom of the compression block while avoiding the occurrence of dislocation phenomena, resulting in high installation stability.

Detailed implementation manners

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0031] As Figures 1 - 7As shown in the figure, the anti-displacement quick-installation medium pressure block includes two top plates 201 that are close to each other. The gap between the two top plates 201 is the installation and fitting gap 206. At one end of one top plate 201 away from the installation and fitting gap 206, a first pressing plate 200 extending downward is fixed, and at one end of the other top plate 201 away from the installation and fitting gap 206, a second pressing plate 2001 extending downward is fixed. At the relative two ends of the top plate 201 avoiding the positions of the first pressing plate 200 and the second pressing plate 2001, a pressing side plate 204 is fixed respectively. On the side wall of the first pressing plate 200 away from the second pressing plate 2001, a limiting piece 302 is fixed. On the side wall of the second pressing plate 2001 away from the first pressing plate 200, a limiting piece 302 is fixed. The free end of the limiting piece 302 extends obliquely upward;

[0032] The pressing side plate 204 includes a first extension plate and a second extension plate connected end to end. The first extension plate is connected and fixed to the top plate 201. The plane of the first extension plate is inclined downward relative to the top plate 201, and the plane of the second extension plate is inclined upward relative to the plane of the first extension plate;

[0033] The bottom ends of the first pressing plate 200 and the second pressing plate 2001 are fixedly connected.

[0034] In the areas of the first pressing plate 200 and the second pressing plate 2001 close to the limiting piece 302, an activity groove 301 is opened. The opening area of the activity groove 301 is larger than the surface area of the limiting piece 302 on the side close to the activity groove 301.

[0035] The first pressing plate 200 includes a first L-shaped plate 202 connected and fixed to the top plate 201. At one end of the first L-shaped plate 202 away from the top plate 201, a third L-shaped plate 203 is connected and fixed; the second pressing plate 2001 includes a second L-shaped plate 2021 connected and fixed to the top plate 201. At one end of the second L-shaped plate 2021 away from the top plate 201, a fourth L-shaped plate 2031 is connected and fixed; the bottom ends of the third L-shaped plate 203 and the fourth L-shaped plate 2031 are integrally formed and fixedly connected; the activity groove 301 and the limiting piece 302 are located on the third L-shaped plate 203 and the fourth L-shaped plate 2031.

[0036] The included angle between the plane of the first extension plate and the plane of the top plate 201 is 13°, and the included angle between the plane of the second extension plate and the plane of the first extension plate is 183°.

[0037] Reinforcing ribs 205 are arranged on the second extension plate.

[0038] With the above technical solution, multiple photovoltaic panels 102 are installed on the C-shaped steel 101. A pressing block 103 is installed from the gap between adjacent photovoltaic panels 102. The pressing block 103 is forced towards the inside of the C-shaped steel 101. The limiting piece 302 is squeezed by the C-shaped steel 101, and the limiting piece 302, the first abutting plate 200, and the second abutting plate 2001 generate elastic deformation towards the middle of the pressing block 103; the bottom of the pressing side plate 204 abuts against the top surface of the frame of the photovoltaic panel 102, and continues to apply force to the pressing block 103, and the pressing side plate 204 generates elastic deformation; continue to apply force to the pressing block 103 until the limiting piece 302 is embedded in the groove of the C-shaped steel 101. At this time, the limiting piece 302 and the pressing side plate 204 complete the clamping and fixing of the C-shaped steel 101 and two adjacent photovoltaic panels 102, and have a tendency to recover deformation, so that the fixing effect of the photovoltaic panel 102 is good, and it has an elastic adaptation function to cope with external impact forces, prolonging the service life of the C-shaped steel 101, the photovoltaic panel 102, and the pressing block 103, and reducing the maintenance cost; during the above installation process, the gap of the installation fit gap 206 is not 0 in the initial state. After the installation is completed, due to the C-shaped steel squeezing, the first abutting plate 200 and the second abutting plate 2001 approach each other, and the gap of the installation fit gap 206 becomes 0. This solution uses the method of reserving the installation fit gap 206 at the top of the pressing block to replace the technical solution of truncating at the bottom junction of the first abutting plate 200 and the second abutting plate 2001 in the prior art. Compared with the prior art solution, in the prior art, the junction of 200 and the second abutting plate 2001 needs to abut against each other to maintain the rigidity of the lower half of the pressing block 103, so that the fixing stability of the photovoltaic panel is good. However, during the installation process, as Figure 8 shown, due to the squeezing effect, the probability of dislocation at the junction of the first abutting plate 200 and the second abutting plate 2001 is large. And once dislocation occurs, due to the friction force, it is difficult for the junction of the first abutting plate 200 and the second abutting plate 2001 to rebound to the initial state, and the junction of the first abutting plate 200 and the second abutting plate 2001 cannot abut against each other. At this time, tools need to be used to manually reset to the initial state, and the installation process is cumbersome; this solution designs the installation fit gap 206 as the deformation space during the installation process, which can avoid the occurrence of dislocation while ensuring the lateral supporting force at the bottom of the pressing block 103, and the installation efficiency is high.

[0039] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
