It should be noted that, for convenience of description, only the portions related to the utility model are shown in the drawings.

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.

As shown in fig. 1 to 5, a frame assembly according to an embodiment of the present utility model includes: the side strip comprises a side strip main body 1, a positioning piece 2, a clamping piece 3, an elastic piece 4 and the like.

The frame component can refer to a frame formed by sequentially connecting a plurality of edges end to end, and can also be one edge of the frame. For example, fig. 1 is one side of the frame, and fig. 8 is a frame with a rectangular structure formed by connecting four sides end to end in sequence, where the structures of the four sides may be the same or different.

The edge strip main body 1 may be, for example, but not limited to, a strip-shaped section, and the material of the strip main body may be aluminum alloy, steel, etc. so as to reduce the overall weight of the frame assembly.

In this example, an aluminum alloy profile may be used, and the edge strip body 1 may be formed by cutting a predetermined length.

The locating piece 2 is fixedly connected with the strake main body 1.

In this example, the positioning member 2 and the strake body 1 are fixedly connected by the bolt 6, however, in other examples, the positioning member 2 and the strake body 1 may also be fixedly connected by clamping, welding, or the like, which is not limited uniquely herein, as long as the positioning member 2 and the strake body 1 can be fixedly connected.

The positioning element 2 is used at least for positioning the frame component with the component 7 to be connected during assembly. For example, when the photovoltaic module is mounted on a purlin, the positioning member 2 is inserted into a groove included in the purlin.

At least one clamping piece 3, clamping piece 3 with strake main part 1 sliding fit, clamping piece 3 with be provided with elastic component 4 between strake main part 1 or the setting element 2, elastic component 4 is used for making clamping piece 3 resets along its slip direction, so that clamping piece 3 with wait to connect part 7 joint cooperation.

The clamping member 3 is a member for clamping and matching with the member to be connected 7, and its specific shape can be determined according to the member to be connected 7 that is clamped and connected in actual need, and the specific structure is not limited uniquely here.

For example, but not limited to, in this example, the clamping member 3 is a hook, and the hook includes a connecting seat 31 and a hook body 33 integrally connected with the connecting seat 31, a clamping space 32 opening towards the to-be-connected component 7 is provided between the hook body 33 and the connecting seat 31, and according to the to-be-connected component 7, the opening of the clamping space 32 formed between the hook body 33 and the connecting seat 31 faces towards or faces away from the positioning member 2, as shown in fig. 5, the opening of the clamping space 32 faces towards the positioning member 2, as shown in fig. 6, and the opening of the clamping space 32 faces away from the positioning member 2. The hook body 33 is provided with an inclined surface at one end far away from the connecting seat 31, and in the direction far away from the connecting seat 31, the inclined surface is inclined towards the direction far away from or near the positioning piece 2, and the inclined surface and the opening are positioned at the same side of the hook body 33. During installation, along with the downward movement of the frame assembly, the to-be-connected part 7 contacts with the inclined plane to generate a component force for driving the clamping part 3 to slide, and under the action of the component force, the clamping part 3 slides until the to-be-connected part 7 reaches the opening, and the clamping part 3 resets under the action of the elastic part 4, so that one part of the to-be-connected part 7 is positioned in the clamping space 32 to realize clamping fit of the clamping part 3 and the to-be-connected part 7.

The elastic member 4 may be a tension spring or a compression spring.

Specifically, whether the elastic member 4 adopts a tension spring or a compression spring may be determined according to the connection position of both ends of the elastic member 4 and the return direction of the clip 3.
