Abstract
The utility model relates to a splayed current collector. The splayed current collector comprises a support, two splayed tension arms hinged on the support, collecting brushes respectively disposed on a lower end of each tension arm, a first spring connecting the two tension arms disposed between the two tension arms, a second spring and a third spring respectively disposed between each tension arm and the support. The first spring, the second spring and the third spring form a triangular supporting structure. Through the first spring connecting the two tension arms, and the second spring and the third spring connecting the support and the two tension arms, the three forms a triangular structure. An isosceles triangular structure is formed by the three, so that uniform and stable forces are applied on the two tension arms, thereby enabling the two collecting brushes on lower parts of the tension arms to contact stably and preferably with guide rails all the time. The splayed current collector ensures normal and safe operation of a whole slide wire system.
Description
Technical field
The utility model relates to a kind of splayed current-collector, belongs to the slick line system parts.
Background technology
Current-collector is the main device that in sliding contact line system, the current collection side is picked up electric energy, and it is directly conducted to electrical appliance by the sliding contact of collecting brush and guide rail with electric energy, thereby realizes the mobile power supply of system.Current-collector is comprised of the tensioner of mechanical structure and collecting brush two parts of direct and guide rail sliding contact.
The tensioner determined set brush of mechanical structure and the sliding contact pressure of guide rail and the stability of mechanism, because current-collector generally comprises two collecting brushes, therefore should make the two stressed equalizations of collecting brush, stability under loading by tensioner, make two collecting brushes all form good contact with guide rail; And existing tensioner or complex structure, or collecting brush can not be stable forms good contact with guide rail, thus affect the safe operation quality of slick line system really, need further be improved.
The utility model content
The utility model is for defects, and it is a kind of simple in structure that purpose is to provide, and can have good application of force effect, thereby makes collecting brush and guide rail can form the stable splayed current-collector that contacts.
The technical solution adopted in the utility model is for this reason: the utility model comprises support and is hinged on two on support and is splay tension arm, and each tension arm lower end arranges respectively collecting brush; Be provided with the spring one that connects two tension arms between two tension arms, each tension arm and support are established respectively spring two and spring three, and spring one, spring two, spring three form a triangular support structure.
Described spring one, spring two, spring three form a symmetrically arranged isosceles triangular structure.
The utility model has the advantages that: the utility model connects two tension arms by spring one, with crossing spring two, spring three connection brackets and two tension arms, form a triangular structure between the three, the utility model preferentially forms the three one isosceles triangular structure, thereby make two tension arms can be subject to equalization, stable tension force, with the two collecting brush all-the-time stable that guarantee to be arranged on its underpart form good contact with guide rail, guaranteed the normal safe operation of whole slick line system.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that support, 2 is that tension arm, 3 is that spring one, 4 is that spring two, 5 is that spring three, 6 is collecting brush.
Embodiment
The utility model comprises support 1 and is hinged on two on support 1 and be splay tension arm 2, and each tension arm 2 lower ends arrange respectively collecting brush 6; Be provided with the spring 1 that connects two tension arms 2 between two tension arms 2, each tension arm 2 and support 1 support are established respectively spring 24 and spring 35, and spring 1, spring 24, spring 35 form a triangular support structure.
Described spring 1, spring 24, spring 35 form a symmetrically arranged isosceles triangular structure.
