[0032] Please refer to Figure 1~Figure 3 The embodiment of the utility model provides a pressing block assembly for installing a photovoltaic module 01, comprising: a first pressing block 10, a second pressing block 20, a fastener 50, a connecting rod 30 and an elastic clamping member 40, wherein the first pressing block 10 is used to press on the side of the upper surface of two adjacent photovoltaic modules 01, the second pressing block 20 is used to press on the side of the lower surface of two adjacent photovoltaic modules 01, the fastener 50 is used to connect the first pressing block 10 and the second pressing block 20, wherein the fastener 50 comprises a bolt 51, a nut 52 and a gasket 53, the bolt 51 passes through the first pressing block 10 and the second pressing block 20, the nut 52 and the gasket 53 are connected to the bolt 51, as shown in FIG. Figure 1 As shown, an upwardly protruding structure can be provided in the middle of the first pressing block 10, and the bolt 51 is connected to the second pressing block 20 and the first pressing block 10 from bottom to top, and the nut 52 and the gasket 53 are connected to the protruding end of the bolt 51 and are located at the upper part of the protrusion. One end of the connecting rod 30 is clamped with the first pressing block 10 or the second pressing block 20 through the elastic clamping member 40, or the two ends of the connecting rod 30 are respectively clamped with the first pressing block 10 and the second pressing block 20 through the elastic clamping member 40. After the connecting rod 30 is connected with the first pressing block 10 or the second pressing block 20, the elastic clamping member 40 can apply a corresponding elastic force. After the assembly is completed, the elastic clamping member 40 can prevent the first pressing block 10 and the second pressing block 20 from moving in directions away from each other. Compared with the traditional assembly method using a single fastener 50, by adding the elastic clamping member 40, the connection stability between the first pressing block 10 and the second pressing block 20 and the photovoltaic module 01 can be effectively improved.

[0033] In some embodiments, the elastic clamping member 40 includes an elastic member 41 and a clamping block 42. The clamping block 42 is connected to the side wall of the connecting rod 30 through the elastic member 41. The elastic member 41 is preferably a spring. The first pressure block 10 and / or the second pressure block 20 are provided with a clamping hole 22. Specifically, when one end of the connecting rod 30 is fixedly connected to the first pressure block 10, the side wall of the other end of the connecting rod 30 is provided with an elastic clamping member 40, and the second pressure block 20 is provided with a clamping hole 22 that cooperates with the elastic clamping member 40; when one end of the connecting rod 30 is fixedly connected to the second pressure block 20, the side wall of the other end of the connecting rod 30 is provided with an elastic clamping member 40, and the first pressure block 10 is provided with a clamping hole 22 that cooperates with the elastic clamping member 40; when the side walls of both ends of the connecting rod 30 are provided with elastic clamping members 40, the first pressure block 10 and the second pressure block 20 are respectively provided with a clamping hole 22. A clamping groove 221 is provided on the inner side wall of the clamping hole 22, and the clamping block 42 is clamped in the clamping groove 221 under the elastic force of the elastic member 41. In order to improve the connection stability between the connecting rod 30 and the first pressing block 10 and / or the second pressing block 20, a plurality of groups of elastic clamping members 40 distributed along the axial direction of the connecting rod 30 can be provided, and a plurality of elastic clamping members 40 can also be distributed along the circumference of the connecting rod 30. It should be noted that the above is to set the elastic clamping member 40 on the connecting rod 30, and the elastic clamping member 40 can also be set in the clamping hole 22 of the first pressing block 10 or the second pressing block 20, and the clamping groove 221 is provided on the side wall of the connecting rod 30, as long as the clamping relationship between the connecting rod 30 and the first pressing block 10 or the second pressing block 20 can be achieved.

[0034] In some embodiments, Figure 3 As shown, a receiving groove 31 is provided on the side wall of the connecting rod 30, one end of the elastic member 41 is connected to the receiving groove 31, and the other end is connected to the clamping block 42, and a guide inclined surface 422 is provided on the side of the clamping block 42 away from the elastic member 41. When the connecting rod 30 is inserted into the clamping hole 22, the clamping block 42 shrinks into the receiving groove 31 under the action of the guide inclined surface 422 and the opening of the clamping hole 22, and when the connecting rod 30 moves to the point where the clamping block 42 corresponds to the clamping groove 221, the clamping block 42 extends into the clamping groove 221 under the elastic force of the elastic member 41. The guide inclined surface 422 can facilitate the shrinkage of the clamping block 42, which can improve the convenience of the user during assembly.

[0035] In some embodiments, one end of the block 42 is hinged to the notch of the receiving groove 31 through the hinge shaft 32, one end of the elastic member 41 is connected to the inside of the receiving groove 31, and the other end is connected to the body of the block 42. Figure 3As shown, the lower end of the block 42 is hinged to the bottom edge of the slot of the receiving groove 31 through the hinge shaft 32, and the left end of the block 42 is connected to the inside of the receiving groove 31 through the elastic member 41. The block 42 can rotate around the hinge shaft 32 toward the inside of the receiving groove 31, so that when assembling, the connecting rod 30 moves relative to the clamping hole 22, and rotates to the outside of the receiving groove 31 under the elastic force of the elastic member 41 to extend into the clamping groove 221. The block 42 can only rotate within a certain range. When rotating into the receiving groove 31, it is necessary to ensure that the block 42 falls within the range of the clamping hole 22, so that the connecting rod 30 carries the block 42 and extends into the clamping hole 22; when rotating toward the outside of the receiving groove 31, it is necessary to ensure that the block 42 is clamped in the clamping groove 221.

[0036] In some embodiments, the block 42 is a triangular block with a triangular cross section, the slot 221 is a triangular slot with a triangular cross section, the first end of the triangular block is hinged at the notch of the accommodating slot 31, and the second end of the triangular block is clamped in the triangular slot. Figure 3 As shown, the inclined surface on the right side of the triangular block is a guiding inclined surface 422. When the connecting rod 30 is inserted downward into the engaging hole 22 on the second pressing block 20, the triangular block will swing to the left around the hinge shaft 32 under the action of the guiding inclined surface 422. When the block 42 moves to correspond to the slot 221, the block 42 swings to the right under the action of the elastic member 41 to be inserted into the slot 221. When the connecting rod 30 is pulled upward, the block 42 acts as a barrier, thereby limiting the first pressing block 10 and the second pressing block 20 from moving away from each other. It should be noted that Figure 3 The block 42 and the slot 221 are only a preferred right-angled triangle structure. In addition, other triangle structures can also be selected, such as an obtuse triangle, in which one acute angle of the obtuse triangle block is hinged to the accommodating groove 31 and the other acute angle is clamped in the slot 221.

[0037] In some embodiments, the block 42 has a clamping plane 421, and the slot 221 has a limiting plane 222. When the block 42 is inserted into the slot 221, the block 42 contacts the limiting plane 222 in the slot 221 through the clamping plane 421 to prevent the first pressing block 10 and the second pressing block 20 from moving in directions away from each other. Figure 3 As shown, the upper surface of the clamping block 42 is a clamping plane 421 , and the inner bottom surface of the clamping slot 221 is a limiting plane 222 , so that the connecting rod 30 can only move downward relative to the second pressing block 20 but cannot move upward.

[0038] In some embodiments, Figure 1As shown, the first pressing block 10 and the second pressing block 20 are connected by two groups of connecting rods 30 and elastic clips 40, and the two groups of connecting rods 30 are respectively located on both sides of the fastener 50. The two connecting rods 30 are preferably symmetrically arranged on both sides of the fastener 50. Through the two groups of connecting rods 30 and the elastic clips 40, the connection stability of the first pressing block 10 and the second pressing block 20 can be improved.

[0039] In some embodiments, a first connection portion is provided on the side of the first pressing block 10 facing the second pressing block 20, and a second connection portion is provided on the side of the second pressing block 20 facing the first pressing block 10. The first connection portion and the second connection portion extend toward each other and are located between two adjacent photovoltaic modules 01, wherein the first connection portion and the second connection portion can play a lateral limiting role on the photovoltaic module 01 to ensure the accuracy of the position of the two adjacent photovoltaic modules 01. Two first connection portions can be provided on the first pressing block 10, and the two first connection portions are respectively located on both sides of the fastener 50, and two second connection portions can be provided on the second pressing block 20, and the two second connections are respectively located on both sides of the fastener 50.

[0040] In some embodiments, a first pressing plate 11 is provided on a side of the first pressing block 10 facing the photovoltaic component 01, and a first suction cup 111 adsorbed on the photovoltaic component 01 is provided on the first pressing plate 11. Figure 4 As shown, the first pressing plate 11 is provided with a plurality of first suction cups 111 in a rectangular array; and / or the second pressing block 20 is provided with a second pressing plate 21 on the side facing the photovoltaic component 01, and the second pressing plate 21 is provided with a second suction cup adsorbed on the photovoltaic component 01. The first pressing plate 11 and the second pressing plate 21 are preferably flexible pressing plates, which can improve the friction with the photovoltaic component 01 on the one hand, and avoid damage to the photovoltaic component 01 on the other hand. For the structure of the first pressing plate 11 and the second pressing plate 21, please refer to Figure 1 As shown, the L-shaped plate is preferably used, and the vertical plate of the L-shaped plate can play a role in lateral positioning of the photovoltaic module 01, and the L-shaped plate can also protect the edges of the photovoltaic module 01. In addition, in order to reduce the weight of the first pressing block 10 and the second pressing block 20, weight-reducing holes can be provided on the first pressing block 10 and the second pressing block 20, for example, T-shaped weight-reducing holes can be provided on opposite sides of the first pressing block 10 and the second pressing block 20, and weight-reducing holes of structural shapes can also be selected.
