Description

Technical Field

[0001] This utility model relates to the field of heater manufacturing technology, specifically to a heater circuit board with a quick positioning structure. Background Technology

[0002] Heaters are commonly used heating devices in winter and play an important role in people's daily lives. In the production process of heaters, the wiring of the circuit board is a key step. The circuit board needs to connect multiple components, such as heating elements, switches, thermostats, etc., to realize the various functions of the heater.

[0003] In the production and maintenance of heaters, accurate positioning ensures that the circuit board is correctly connected to other components, guaranteeing the normal operation of the heater. Traditional heater circuit board installation methods often require operators to determine the position of the circuit board based on experience and visual inspection, and then fix it with multiple screws or clips. This method is not only time-consuming, but also requires high skill from the operators. In large-scale production, the problem of low efficiency is particularly prominent, affecting the overall production progress. Therefore, there is an urgent need for a heater circuit board with a quick positioning structure to overcome the above defects. Utility Model Content

[0004] The purpose of this invention is to provide a heater circuit board with a quick positioning structure, which has the advantages of convenient and quick positioning, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heater circuit board with a quick positioning structure, comprising a protective shell assembly, a heater circuit board body, a snap-fit ​​assembly, and a reinforcing assembly. The heater circuit board body is disposed within the inner cavity of the protective shell assembly. The snap-fit ​​assemblies are all disposed around the bottom of the heater circuit board body. The reinforcing assemblies are all disposed on both sides of the heater circuit board body. The protective shell assembly includes a top cover, a bottom shell, a slot, a groove, and an arc-shaped groove. The snap-fit ​​assembly includes a receiving seat, a locking rod, a first slider, a first sliding groove, and a first spring. The reinforcing assembly includes a mounting seat, a limiting groove, a limiting rod, an inclined locking block, a second sliding groove, a second spring, and a second slider.

[0006] Furthermore, a card holder is fixedly installed around the bottom of the inner cavity of the bottom outer shell, and an arc-shaped groove is opened on both sides of the inner cavity of the card holder, and a card slot is opened on both sides of the inner cavity of the bottom outer shell.

[0007] Furthermore, a heater circuit board body is provided on the top of the bottom outer shell, and a receiving seat is fixedly installed on all four sides of the bottom of the heater circuit board body. A first sliding groove is provided on both sides of the inner cavity of the receiving seat.

[0008] Furthermore, two first sliders are slidably connected inside the first slide groove. A locking rod is fixedly installed on the side of the first slider that is relatively close to each other. A first spring is fixedly installed in the inner cavity of the first slide groove on the side of the first slider that is relatively close to each other.

[0009] Furthermore, mounting bases are fixedly installed on both the left and right sides of the heater circuit board body, and a limiting groove is formed at the top of the inner cavity of the mounting base, with a limiting rod slidably connected to the inner cavity of the limiting groove.

[0010] Furthermore, a second sliding groove is provided on both sides of the inner cavity of the mounting base, and a second slider is slidably connected inside the second sliding groove. The side of the second slider that is relatively close to the other side is fixedly connected to both sides of the inclined block.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are: This invention protects the heater circuit board body by setting a protective outer shell assembly, and enables quick insertion of the heater circuit board body during installation by setting a snap-fit ​​assembly, thereby improving production efficiency. A reinforcement assembly reinforces both sides of the heater circuit board body. In use, the heater circuit board body is first moved downwards. Under the action of a first spring, a first slider drives a locking rod through an arc-shaped groove into the interior of the locking seat. Simultaneously, the receiving seat enters the inner cavity of the locking seat, limiting the bottom of the heater circuit board body. Then, under the action of force, an inclined locking block passes through a slot into the interior of the bottom outer shell, thereby limiting both sides of the heater circuit board body. After limiting, the top cover is placed on top of the bottom outer shell and fixed with bolts. This method has the advantage of convenient and quick positioning, solving the problem that traditional heater circuit board installation methods often require operators to determine the circuit board position by experience and visual inspection, and then fix it with multiple screws or clips. This method is not only time-consuming but also requires high operator skills, and its low efficiency is particularly prominent in large-scale production, affecting the overall production progress.
