Referring to fig. 1 to 4 in combination, the upper press block 100 includes a first fixing portion 110, a second fixing portion 120 and a fastening portion 130, the first fixing portion 110 is located on a first side (left side as viewed in fig. 4) of the fastening portion 130, the second fixing portion 120 is located on a second side (right side as viewed in fig. 4) of the fastening portion 130, and the first fixing portion 110 and the second fixing portion 120 are respectively adapted to be engaged with two adjacent profiles 20 as shown in fig. 1. Specifically, the first fixing portion 110 and the second fixing portion 120 are respectively clamped with the notch lower ends 23 of the side grooves 22 of the two adjacent profiles 20.

Further, the upper pressing block 110 in the present embodiment further includes a first groove 111 and a second groove 121, where the first groove 111 is located between the first fixing portion 110 and the fastening portion 130, and the second groove 121 is located between the second fixing portion 120 and the fastening portion 130. Referring further to fig. 10 in combination, for ease of understanding, the adjacent two profiles 20 of the press block assembly 10 are designated as a first profile 20a and a second profile 20b, respectively, and when the upper press block 100 is engaged with the first profile 20a and the second profile 20b, the lower end 23a of the side slot of the first profile 20a is adapted to be engaged with the first groove 111, and the lower end 23b of the side slot of the second profile 20b is adapted to be engaged with the second groove 121.

As shown in fig. 1 to 4, a preferred embodiment of the present application is one in which a first vertical distance H1 is provided between the lower end 23 of the slot of the side slot 22 of the middle section bar 20 and the lower surface of the section bar 20, a second vertical distance H2 is provided between the first groove 111, the second groove 121 of the upper press block 100 and the lower surface of the fastening part 130 in the vertical direction, and H1> H2.

Fig. 5 is a schematic perspective view of a pressing block according to an embodiment of the present application, and fig. 6 is a front view of the pressing block according to an embodiment of the present application. Referring to fig. 1-2 and 5-6 in combination, the pressing block 200 includes a third fixing portion 210, a fourth fixing portion 220, and a loading plate 230, wherein the third fixing portion 210 is positioned at a first side (left side as viewed in fig. 6) of the loading plate 230, and the fourth fixing portion 220 is positioned at a second side (right side as viewed in fig. 6) of the loading plate 230. Specifically, the third fixing portion 210 has a protruding strip 211, and a rim (an upper rim as shown in fig. 6) of the protruding strip 211 away from the carrier 230 has a flange 212, and the flange 212 protrudes from the upper rim of the protruding strip 211 toward the fourth fixing portion 220, so that the third fixing portion 210 forms a hook similar to a "J" shape, and is suitable for being engaged with the fixing plate 21 of the corresponding profile 20. After the fixing is completed, the protrusion 211 can restrict the movement of the profile 20 in the horizontal direction, and the flange 212 can restrict the movement of the profile 20 in the vertical direction to some extent.

Further, the fourth fixing portion 220 has an upturned edge 221 and a clamping groove 222, and the clamping groove 222 is located between the upturned edge 221 and the carrying plate 230 and is adapted to slide into the fixing plate 21 of the connecting counterpart profile 20. It will be appreciated that the third fixing portion 210 and the fourth fixing portion 220 of the lower pressing block 200 are respectively adapted to fix two adjacent profiles 20, and further referring to fig. 10, the third fixing portion 210 is adapted to be engaged with the fixing plate 21a of the first profile 20a, and the clamping groove 222 of the fourth fixing portion 220 is adapted to slide into the fixing plate 22b connected to the second profile 20 b.

Fig. 1 to 6 are preferred embodiments of the present application, in which a first horizontal distance L1 (refer to fig. 1) is provided between an end S1 of a side slot 22 of a medium 20, which is far from a fixed plate 21, and an end S2 of the fixed plate 21, which is far from the side slot 22, a second horizontal distance L2 (refer to fig. 4) is provided between both sides of a fastening portion 130 of an upper press block 100, a third horizontal distance L3 (refer to fig. 6) is provided between both edges of an upper surface of a carrier 230 of a lower press block 200, a protrusion distance L4 (refer to fig. 6) is provided between a flange 212 and a protrusion 211, and 0< L3-2×l1-L2 is equal to or less than L4. Taking fig. 9-10 as an example, 2xl1+l2 is the distance between Sa2 and Sb2 after the first profile 20a, the second profile 20b, and the press block assembly 10 are combined together, sa2 is the end of the fixing plate 21a of the first profile 20a away from the side slot 22a, and Sb2 is the end of the fixing plate 21b of the second profile 20b away from the side slot 22b.

It can be appreciated that, in order to ensure that the first profile 20a can be snapped into the third fixing portion 210 under the action of gravity, L3 needs to be greater than 2×l1+l2, i.e. Sa2, sb2 will not abut against two edges of the upper surface of the carrier plate 230 at the same time. Assuming that Sb2 has abutted against the edge of the upper surface of the carrier plate 230 (the right edge as shown in fig. 10, i.e., the bottom of the clamping groove 222), there is a gap between Sa2 and the other edge of the upper surface of the carrier plate 230 (the left edge as shown in fig. 10), and the width of the gap is equal to L3-2×l1-L2. However, an excessive L3 may affect the fixing effect of the lower press block 200, so that the width of the gap is smaller than the protruding distance L4 of the flange 212 relative to the protrusion 211, so that the fixing plate 21a of the first profile 20a is not separated from the third fixing portion 210 in the vertical direction without an external force.

The present invention also provides a method of installing the compact assembly 10. Fig. 7-10 are schematic views of a press block assembly and profile mating process according to an embodiment of the present application. Referring to fig. 3-10, the assembly process of the press block assembly 10 and the profiles 20a, 20b is described in detail as follows:

(1) Referring to fig. 1-7, first, the second profile 20b with the photovoltaic laminate 40 and the press block assembly 10 are placed on the bracket 30, and it should be noted that the lower press block 200 needs to be placed between the second profile 20b and the bracket 30, and the fixing plate 21b of the second profile 20b is located on the carrier plate 230. At this time, the upper press block 100 is suspended, the second groove 121 of the upper press block 100 is aligned with the side groove notch lower end 23b of the second profile 20b, and the fastener 300 (not shown) is temporarily not installed.

(2) Referring to fig. 1 to 6, 8, the lower press block 200 is translated along the bracket 30 in a direction away from the second profile 20b until the fixing plate 21b of the second profile 20b slides into the clamping groove 222, and then the upper press block 100 is placed downward until the notch lower end 23b of the second profile 20b is caught in the second groove 121 of the upper press block 100. At this time, the first fastening holes 101 of the upper press block 100 and the second fastening holes 201 of the lower press block 200 are opposite, and the fastening member 300 is installed to pass through the first fastening holes 101, the second fastening holes 201, and the locking member 400 (not shown, refer to fig. 2) in order and tightened, thereby fixing the second profile 20b on the bracket 30.

(3) Referring to fig. 1 to 6, 9, the first profile 20a mounted with the photovoltaic laminate 40 is obliquely placed on the lower press block 200 such that the lower end 23a of the side groove notch thereof is inserted between the first fixing portion 110 of the upper press block 100 and the carrier plate 230 of the lower press block 200, and the fixing plate 21a of the first profile 20a is overlapped on the flange 212 of the lower press block 200.

(4) Referring to fig. 1-6 and 10, the first profile 20a is laid flat, and under the weight of the photovoltaic laminate 40 and the first profile 20a, the fixing plate 21a of the first profile 20a is caught under the flange 212, and the notch lower end 23a of the side groove 22a is caught in the first groove 111 of the upper press block 100, and the installation is completed. It should be noted that the protruding distance L4 between the flange 212 and the protruding strip 211 needs to be less than a threshold, which is the maximum protruding degree of the flange 212, and when the flange 212 is less than the threshold, the first profile 20a naturally lays flat, so that the fixing plate 21a can be clamped under the flange 212.

Specifically, after the second profile 20b on one side of the press block assembly 10 is installed, a worker can directly tighten the fastener 300 and then continuously install the first profile 20a on the other side, without operating the press block assembly 10 already arranged between two adjacent profiles 20, so that the operation difficulty is reduced, and meanwhile, the risk of irregular operation such as kneeling photovoltaic modules and the like of the worker is avoided.

In addition, when the first and second profiles 20a and 20b and the press block assembly 100 are installed as shown in fig. 10, the next step should be to continue to install another press block assembly 10 on the other side of the first photovoltaic module 50a on which the first profile 20a is installed, as shown in fig. 7: it will be appreciated that the position of the first photovoltaic module 50a is now fixed and cannot be moved any more, and therefore only the compact assembly 10 can be translated. Specifically, the unfixed end of the first photovoltaic module 50a is lifted, so that a gap is left between the first profile 20a and the bracket 30 to enable the other lower pressing block 200 to slide in, and the following steps can be referred to in (1) to (4) above.

Referring to fig. 7-10, the disassembly process also does not require the operation of the press block assembly 10 already disposed between two adjacent profiles 20: first, the first profile 20a is lifted upward, and the fixing plate 21a thereof is disengaged from the third fastening portion 210, and the worker can directly detach the press block assembly 10. After the fastener 300 is unscrewed, the upper press block 100 can be directly taken out, and the lower press block 200 needs to translate along the bracket 30 towards the direction of the second section bar 20b until the fixing plate 21b slides out of the clamping groove 222 (refer to fig. 6), and then the second section bar 20b is lifted up to take out the lower press block 200.

Further, referring to fig. 1-6 and 10 in combination, the upper surface of the upper press block 100 in the press block assembly 10 provided by the invention is lower than the upper surfaces of the two adjacent profiles 20, and is completely located in the installation gap between the two adjacent profiles 20, so that the upper press block 100 does not protrude out of the photovoltaic module after the installation is completed, thereby ensuring the aesthetic property, and the upper press block assembly 100 only fixes the side grooves 22 of the profiles 20, namely, the stress surface is the B surface (i.e. the left side surface as shown in fig. 1) of the profiles 20. In the prior art, the pressing block is often used for pressing the surface A (i.e. the upper surface) of the profile, the fixing method relies on the friction force between the pressing block and the surface A of the profile, the fixing effect is poor, and in order to ensure the fixing strength, the pressing block is often required to have a large pressing force on the profile, however, the upper surface of the photovoltaic laminated piece is possibly cracked. The upper pressing block 100 is used for pressing the bottoms of the side grooves 22 of the profile 20, so that the lateral displacement of the profile 20 is prevented while the pressing force is increased, the photovoltaic laminated piece is prevented from being damaged, and the service life is prolonged.

Furthermore, in the press block assembly 10 provided by the invention, the fixing plate 21 (namely, the extended C-face) of the profile 20 is fixed by the lower press block 200, so that the fixing effect is further enhanced compared with the mode of fixing only the B-face, and the requirement on the thickness of the extended C-face is reduced compared with the mode of fixing only the C-face. Specifically, if only fix section bar B face, thereby under bad weather conditions such as strong wind, the circumstances that can take place the photovoltaic module perk and make the separation between section bar and the briquetting causes economic loss, and only fix extension C face, thereby need C face have certain thickness and intensity avoid the section bar damage to fixed effect is not good. In the invention, the lower press block 200 further fixes the C surface of the press block 20, and an asymmetric design is adopted, the fourth fixing part 220 limits the profile 20 in the vertical direction through the clamping groove 222, and meanwhile, the third fixing part 210 is provided with the convex strips 211 and the flanges 212, so that the problem of difficult installation and disassembly is solved.

Fig. 11 is a schematic perspective view of a briquette assembly according to another embodiment of the present application, and fig. 12 is a schematic perspective view of a lower briquette according to another embodiment of the present application. Referring to fig. 11-12, the press block assembly 10' in this embodiment includes an upper press block 100', a lower press block 200', a fastener 300', a locking member 400', and a piercing screw 500.
