Abstract
The utility model relates to a tool box (i.e. a fish pole packaging box) torsion spring device for angling apparatus belonging to packaging product technical field and is technically characterized in that: a box body is arranged and fixed thereon with a box cover and a torsion spring through a metal pin with running fit adopted between the box cover and the metal pin; one jaw of the torsion spring is lap jointed to the box body, while the other jaw to the cover plate. When opening the box cover of the utility model, user only needs to pull backwards the switch and the jaw of the torsion spring exerting force upwards flicks the box cover automatically; in addition, the utility model is simple in structure and convenient in use.
Description
Affiliated technical field
The utility model relates to a kind of packaging product technical field, specifically a kind of torsion spring device that holds Fishing device with instrument cases.
Background technology
We know that generally its lid of the instrument cases of Shi Yonging is that hand lifts, and require great effort very much when uncapping operation.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of instrument cases torsion spring device, and this instrument cases torsion spring apparatus structure is simple, easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: be provided with box body, be fixed with lid and torsion spring through metallic pin on the box body, lid and metallic pin are rotatably assorted, and a pawl of torsion spring rides on the box body, and the another one pawl of torsion spring rides on the cover plate.
The beneficial effects of the utility model are, only need pull back switch if will open the lid, and the pawl that torsion spring is upwards exerted oneself will automatically spring open lid, and is simple in structure, easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an open mode schematic diagram of the present utility model.
1. switches among the figure, 2. boss, 3. dewclaw, 4. torsion spring, 5. lower claw.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model metallic pin passes cover plate and torsion spring 4 and is fixed on the box body, cover plate can rotate around metallic pin, torsion spring 4 has two pawls, the dewclaw 3 of torsion spring 4 rides on the box body, lower claw 5 rides on the cover plate, cover plate is more to pressing down, and torsion spring 4 is stressed big more, and the position that cover plate contacts with switch 1 is processed with downward boss 2, when closing upper cover plate, this boss 2 is pinned by switch 1, when opening cover plate, only needs downward slide switch 1, boss 2 on the cover plate and switch 1 downward boss breaks away from, and cover plate automatically springs open because of the effect that is subjected to torsion spring 4 dewclaws 3.
