Abstract
The utility model discloses a folding supporting arm with a magnetic pull-in self-locking mechanism, which comprises at least two support arms. The two adjacent support arms are rotationally connected. The folding supporting arm is characterized in that the folding supporting arm is further provided with the magnetic pull-in self-locking mechanism; the magnetic pull-in self-locking mechanism comprises strong magnets which are respectively arranged on opposite surfaces of two adjacent support arms and can be mutually adsorbed. When the support arms need to be collapsed to the parallel positions, each support arm only needs to be closed to a certain angle until the attracting force is generated between the two corresponding strong magnets, so that the support arms can be automatically returned to the parallel positions, a certain locking strength is maintained and the displacement caused by gravity or other vibrations is prevented. Moreover, a gap between the support arms can be reduced under the action of the gravitation, so that the folded folding supporting arm is more attractive integrally.
Description
Technical field
The utility model relates to a kind of collapsible support arm, and especially a kind of tool magnetic closes the collapsible support arm of self-locking mechanism.
Background technique
At present, the collapsible support arm of number of different types is arranged, still above the market; Traditional collapsible support arm does not have lock function or adopts the mechanical caging form on parallel surface; There is following problem in it: 1. because of rotatingshaft has big resistance, when manually forwarding parallel position to and stop the application of force, have and produce bounce-back; Causing between two support arms is not at horizontal position, has influence on flat appearance property; 2. when the support arm of collapsible support arm is in parallel position, under support arm self gravitation and other vibrations, can cause producing between the support arm angle; 3. traditional mechanical caging form need be by unlock switch when opening, troublesome poeration, and cost is higher.
Summary of the invention
The purpose of the utility model aims to provide the collapsible support arm that a kind of tool magnetic closes self-locking mechanism.
The purpose of the utility model realizes through following technological scheme: a kind of tool magnetic closes the collapsible support arm of self-locking mechanism; It comprises at least two support arms; Two adjacent support arms are rotationally connected; It is characterized in that it also has magnetic and closes self-locking mechanism, this magnetic closes self-locking mechanism and is made up of the strong magnet that can adsorb each other on the relative face that is separately positioned on two adjacent support arms.When support arm need fold parallel position; Only need each support arm is closed into several angle, the attraction force to producing between two corresponding strong magnets can automatically revert to parallel position; And keep certain locking force, prevent the displacement that causes because of gravity or other vibrations.And the gap between the support arm makes the integral body after amounting to more attractive in appearance because the effect of gravitation also can reduce.
Two support arms that the utility model is adjacent connect through the rotatingshaft with torsion.
Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model has adopted magnetic force adhesive self-locking mechanism; When angle between the folding arm during less than 10 °, promptly between the strong magnet distance relatively near the time, can produce big gravitation between the strong magnet; Make each support arm get back to parallel position automatically, and keep bigger coupling mechanism force.And the gap between the support arm makes the integral body after amounting to more attractive in appearance because the effect of gravitation also can reduce.
(2) the utility model has adopted magnetic force adhesive self-locking mechanism, and it keeps big coupling mechanism force when parallel position, damage whole support arm thereby therefore when it is moved or transports, can not let support arm open automatically because of gravity or vibrations etc.
(3) the utility model has adopted magnetic force adhesive self-locking mechanism, when opening collapsible support arm, need not to separate locking key by other, and only dynamics can be opened collapsible support arm, simple in structure and safety durable by nature a little.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the utility model embodiment's a exploded view.
Embodiment
The collapsible support arm that tool magnetic shown in Fig. 1～2 closes self-locking mechanism is an embodiment of the utility model; It closes self-locking mechanism by two support arms and magnetic and constitutes; Two support arms are respectively support arm 1 and support arm 2, and they interconnect through the rotatingshaft 5 with torsion.Magnetic closes self-locking mechanism and is made up of with strong magnet 4 strong magnet 3 that can adsorb each other on the relative face that is separately positioned on adjacent support arm 1 and support arm 2.Support arm 1 all comprises housing with support arm 2, and strong magnet 3 and 4 of strong magnets are to be inlaid in respectively in the housing of opposing side of support arm 1 and support arm 2.When support arm 1 and support arm 2 need fold parallel position; Only need support arm 1 and support arm 2 are closed into several angle; This angle is less than 10 °, and the attraction force that will produce between two corresponding strong magnets can automatically revert to parallel position; And keep certain locking force, prevent the displacement that causes because of gravity or other vibrations.And the gap between the support arm makes the integral body after amounting to more attractive in appearance because the effect of gravitation also can reduce.
The utility model can summarizing without prejudice to the spirit of the utility model or the concrete form of major character with other.The above-mentioned embodiment of the utility model all can only be thought explanation rather than the restriction to the utility model; Therefore every essence technology according to the utility model all belongs in the scope of the utility model technological scheme any trickle modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. a tool magnetic closes the collapsible support arm of self-locking mechanism; It comprises at least two support arms; Two adjacent support arms are rotationally connected; It is characterized in that it also has magnetic and closes self-locking mechanism, this magnetic closes self-locking mechanism and is made up of the strong magnet that can adsorb each other on the relative face that is separately positioned on two adjacent support arms.
2. tool magnetic according to claim 1 closes the collapsible support arm of self-locking mechanism, it is characterized in that, described two adjacent support arms connect through the rotatingshaft with torsion.
