Description

PTC heater fixed knot constructs Technical Field The utility model relates to the field of structure and installation of electric heating devices, in particular to a PTC heater fixing structure. Background The PTC heater is generally connected to a power source at both ends thereof to supply power to the heater, so that its fixing structure is very important. In prior art, patent publication No. CN221615178U discloses a fixed knot of PTC heater constructs, including installing support and fixed block, the mounting groove has been seted up to the upside of installing support, the inboard front and back lateral wall of mounting groove is equal symmetrical connection has the slide bar, two the outside of slide bar has all been slided and has been cup jointed fixed preforming, fixed preforming is bar elasticity preforming, left and right sides fixedly connected with PTC heater between the fixed preforming, the wiring hole has been seted up to the front side of installing support, the front side scarf joint of installing support has radiator fan, the grafting groove has been seted up to the front side of fixed block, the inboard bottom fixedly connected with grafting fixture block of grafting groove, the grafting draw-in groove has been seted up to the downside of installing support, and this fixed knot constructs is simple grafting groove fixed, and the time is easy to take place for a long time not hard up, and is stable inadequately. Disclosure of utility model The utility model aims to solve the problems that the existing fixing structure is only fixed by a common inserting groove and has poor structural stability, the limiting flat part and the limiting inclined part are arranged on the first fixing piece, meanwhile, the first bayonet and the second bayonet are arranged on the shell to fix the heater at the same time, so that the PTC heater is not easy to shake when being fixed, and the PTC heater fixing structure with stable structure is provided. The utility model further aims to solve the problem of poor heat dissipation of the existing fixing structure, and provides the PTC heater fixing structure with good heat dissipation effect, wherein the first fixing cavity is arranged, a certain gap is reserved after the PTC heater is inserted. In order to achieve the purpose, the PTC heater fixing structure comprises a first fixing piece and a second fixing piece, wherein one end of a heater is embedded into the first fixing piece, the other end of the heater is embedded into the second fixing piece, the bottom of a shell of the first fixing piece is a support, two sides of the shell are outer arc parts, a first bayonet is arranged in the outer arc parts, a first fixing cavity is formed in the shell, a first limiting block is arranged in the first fixing cavity, and one side of the first limiting block is a limiting inclined part. Preferably, the end part of the first limiting block is a limiting flat part which is propped against the heater, one side of the limiting flat part is an inner inclined part, and the first limiting block has certain elasticity. Preferably, a first positioning block is arranged at the top of the first fixing cavity, and the center of the first positioning block is a first fastening groove. Preferably, one end of the first limiting block is provided with a reinforced cambered surface close to the line connection part. Preferably, the second fixing piece is internally provided with a second positioning block and a second bayonet. Preferably, a second fastening groove is provided in the second positioning block. Preferably, the outer part of the shell corresponding to the second bayonet is a bent part. Preferably, the first bayonet is an inner groove structure, and the inner groove structure is a long strip shape. Preferably, the axis of the first limiting block is arranged on the first bayonet.
