Concealed connection structure of fan heater shell

Abstract

The invention discloses a concealed connection structure of a fan heater shell. The concealed connection structure comprises L-shaped connection plates, a connection plate and a bottom plate; an adjustment hole is formed in the side surface of a connection rod, connection holes are formed in the end surfaces of the connection plate, an accommodating cavity is formed in the connection plate, and sliding grooves are formed in the top and the bottom of the accommodating cavity; sleeves are arranged in the accommodating cavity, the sleeves are fixedly connected with the inner wall of the accommodating cavity through fixing rods, an adjusting rod is arranged in the accommodating cavity, an adjusting gear is fixed to the adjusting rod, and first meshing teeth are fixed to the ends, penetrating through the sleeves, of the adjusting rod; and the first meshing teeth are rotatably connected with a telescopic device, a plurality of clamping-connecting members are fixed to the telescopic device, aplurality of second clamping-connecting members matched with the first clamping-connecting members are fixed to the end surface of the L-shaped connection plates, threaded holes are formed at the corners of the L-shaped connection plates, and first threaded rods are rotatably connected to four corners of a base. The concealed connection structure is concealed inside the connection plate and can be connected with the fan heater shell and regulate the size of the fan heater shell.

Description

technical field [0001] The invention relates to a hidden connection structure of a heater casing, belonging to the technical field of connection structures. Background technique [0002] The heater is a device that people often use in winter, but the connection structure between the casings of the existing heaters is exposed, which affects the appearance of the casing and the long-term exposure of the connection structure will accelerate its aging speed , reduce the service life of the connecting structure. [0003] A hidden connection structure of the heater casing is now being studied, which can have the effect of hiding the connection structure inside the casing, and at the same time can achieve the effect of freely adjusting the size of the casing through the connection structure, ensuring the flexibility and practicality of the connection structure sex. Contents of the invention [0004] The purpose of the present invention is to provide a hidden connection structur...
