The utility model discloses a sealing bottle cap and a packaging bottle, the sealing bottle cap comprises a cap body, the bottom side of the cap body is provided with a lower opening, and the inner side of the cap body is provided with an inner connecting structure; the sealing plug comprises a connecting section, a deformation section, an outer supporting section and a plugging section which are coaxially connected in sequence from inside to outside, the connecting section is connected to the inner top side of the cover body, and the plugging section is located at the top of the outer supporting section; the deformation section can drive the plugging section to leave the inner top side of the cover body in a natural state and enable the outer diameter of the outer supporting section to be reduced, and when the plugging section moves upwards, the deformation section can be driven to elastically deform and enable the outer diameter of the outer supporting section to be increased. The outer diameter of the outer supporting section can be increased to ensure the sealing performance with the bottle opening, and the outer diameter of the outer supporting section can be reduced to reduce the friction force when the outer supporting section is separated from the bottle opening, so that the operation is more labor-saving, and the sealing performance and the operation convenience when the sealing bottle cap is used are better considered.

The utility model provides a photovoltaic module heat dissipation frame relates to photovoltaic equipment technical field, include: photovoltaic board, the edge position of photovoltaic board is provided with the outer frame subassembly, directly with the inner strip frame of outer frame subassembly of photovoltaic board outer end place first sleeve connection, with heat dissipation subassembly and outer frame strip contrast fixed, the fixed component is connected between heat dissipation subassembly and outer frame subassembly, make outer frame subassembly form protection to photovoltaic board outer end, the outer frame subassembly has the installation of convenient heat dissipation subassembly simultaneously, let heat dissipation subassembly close photovoltaic board and contact heat transfer, the back of photovoltaic board installs conducting component simultaneously, let conducting component better heat import heat dissipation subassembly and radiate, and auxiliary component is assisted and let conducting component more closely use, solved the simple heat dissipation structure of current, the heat dissipation structure in the frame position, can not steadily export heat, lead to equipment to photovoltaic board and cause the problem of poor heat dissipation efficiency.
