Abstract

The utility model discloses a rotating mechanism of an electric torch, which comprises a shell, a base, a spring plate and a base cover. The upper part of the shell is provided with a holding cavity for installing a lamp, the lower part of the shell is rotatably hinged on the base, and a circle of shallow bulges and shallow grooves at intervals are formed at the periphery of the hinging part; the base is a cylindrical member and can be sheathed at the lower part of the shell; the spring plate can be inserted into a clearance between the base and the lower part of the shell and movably clamped in the shallow groove at the lower part of the shell; and the base cover can be fastened at the outer end of the base. In the utility model, as a swing mechanism is formed by the spring plate, the shallow bulges and the shallow grooves, the assembly of the swing mechanism can be accomplished just by inserting the spring plate into the clearance between the base and the lower part of the shell and then being fastened with the base cover; and once the spring plate is damaged, the swing mechanism can be repaired only by replacing the damaged spring plate, and the repairing is easy.

Description

The rotating mechanism of flashlight

Technical field

The utility model relates to a kind of flashlight, particularly relates to a kind of rotating mechanism of flashlight.

Background technology

The flashlight of commonly using swung (as shown in Figure 1) comprises housing 1 ', lever 2 ' and swing mechanism 3 '.Swing and can be fixed on arbitrarily on the pendulum angle on its housing 1 ' top that light fixture is installed bottom lever 2 ' relatively.This commonly use can swing flashlight swing mechanism 3 ' mainly by quincunx flap 31 ' and steel ball 32 ', quincunx flap 31 ' is fixed in the housing 1 ', steel ball 32 ' is installed on the lever 2 ', steel ball 32 ' is movable to be arranged in each through hole of quincunx flap 31 ' periphery, thereby forms different swing positions.Because quincunx flap 31 ', steel ball 32 ' just are built in housing 1 ', the lever 2 ' when assembling, and be non-dismountable, in case damage, then can't change, and make flashlight lose the swing function.

The utility model content

The purpose of this utility model is to provide a kind of rotating mechanism of the flashlight that is easy to repair.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of rotating mechanism of flashlight; It mainly is made up of housing, base, shell fragment, base cover; The top of described housing is a containing cavity that light fixture is installed, and lower housing portion is rotating to be hinged on the base, forms the shallow projection in interval and the shallow slot of a circle at the periphery of this hinged place; Described base is a Cylinder shape constructional element, can be socketed in lower housing portion; Described shell fragment can insert gap between base and the lower housing portion and activity holding in the shallow slot of lower housing portion; Described base cover can snap onto the outer end of base.

Offer axis hole on the two side of described lower housing portion symmetry, form the shallow projection in interval and the shallow slot of a circle at the periphery of this axis hole; The projection that extends internally out respectively on symmetrical two madial walls of its of described base, this two projection is rotating respectively to be located in the axis hole of lower housing portion, forms articulated structure.

Described shell fragment has two, its middle part has one and suppresses head, this suppresses head and is connected on the body by elastic arm, elastic arm can be around the link small angle oscillation of itself and body, two shell fragments can insert the gap between base and the lower housing portion respectively and be fixed on the base, on the shell fragment insertion end suppress the head inwardly the activity holding in the shallow slot of lower housing portion.

After adopting such scheme, because being shallow projection, the shallow slot by shell fragment and lower housing portion, swing mechanism of the present utility model constitutes, insert the gap between base and the lower housing portion in when assembling as long as with shell fragment, snapping upper base flap just can be finished the assembling of swing mechanism again, in case shell fragment damages, as long as the shell fragment that damages is changed, just the swing mechanism reparation can be repaired easily.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 commonly uses the structural representation that can swing flashlight;

Fig. 2 is a three-dimensional exploded view of the present utility model;

Fig. 3 is an isometric cutaway view of the present utility model;

Fig. 4 is a pendulum angle of the present utility model.

The specific embodiment

As shown in Figure 2, the utility model is a kind of rotating mechanism of flashlight; It mainly is made up of housing 1, base 2, shell fragment 3, base cover 4.

Described housing 1 can be made up of upper shell and lower house two parts snapping, the top of housing 1 is a containing cavity that light fixture is installed, offer axis hole 11 on the two side of housing 1 bottom symmetry, form the interval shallow protruding 12 and the shallow slot 13 of a circle at the periphery of this axis hole 11, this is shallow protruding 12 triangular in shape, and this shallow slot 13 is rectangle.

Shown in Figure 3 as Fig. 2 reference, described base 2 is a Cylinder shape constructional element, a projection 21 extends internally out respectively on two madial walls of its symmetry, base 2 can be socketed in housing 1 bottom, two projections 21 of its madial wall are rotating respectively to be located in the axis hole 11 of housing 1 bottom, forms articulated structure.In the present embodiment, also projection can be set on housing, and establish axis hole at base, projection on the housing and the axis hole on the base also can form hinged.

Described shell fragment 3 has two, its middle part has one and suppresses 31, this suppresses 31 and is connected on the body 33 by elastic arm 32, elastic arm 32 can be around the link small angle oscillation of itself and body 33, two shell fragments 3 can insert the gap between base 2 and housing 1 bottom respectively and be fixed on the base 2, on shell fragment 3 insertion ends suppress 31 inwardly the activity holding in the shallow slot 13 of housing 1 bottom.

Described base cover 4 can snap onto the outer end of base 2.

Operation principle of the present utility model:

When relative base 2 swings of housing 1, be fixed on suppressing of shell fragment 3 on the

base

2 and 31 from shallow slot 13, deviate from, jump over shallow protruding 12 to enter next or a plurality of shallow slots 13 and holding in this shallow slot 13, thereby form different swing positions (as shown in Figure 4).

Emphasis of the present utility model just is: by shell fragment with and the shallow slot of housing cooperates, realize swinging at any angle.

The above, it only is the utility model preferred embodiment, the shape of shallow projection of lower housing portion and shallow slot can have various, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
