Abstract

The utility model provides a hinge device of a rotating arm, which enables the rotating arm to rotate on a base. The utility model is characterized in that the rotating arm is provided with a pivoting axle; a sleeve ring and a C-shaped sleeve ring seat are orderly sheathed on the outer surface of the pivoting axle, wherein the C-shaped sleeve ring seat has an extending position, and a C-shaped spring sheet is arranged on the periphery of the C-shaped sleeve ring seat; one end of the C-shaped spring sheet extends to the position above the extending position; a locking assembly is used for making a tight relation formed between the C-shaped spring sheet and the C-shaped sleeve ring seat and is arranged on the C-shaped sleeve ring seat by the C-shaped spring sheet, making the force of locking attaching evenly distributed on the surface of the C-shaped sleeve ring seat, and the abrasion of other components is not easily caused. Due to the strong rigidity of the C-shaped spring sheet, the material for the C-shaped sleeve ring seat is reduced, and further, the cost is reduced and the space use is saved.

Description

The articulated mounting of spiral arm

Technical field

The utility model is relevant a kind of rotating beam apparatus, the particularly articulated mounting of relevant a kind of spiral arm.

Background technique

In the employed electrical equipment of daily life, the spiral arm of often electrical equipment must being arranged in pairs or groups, file projector for example, its spiral arm can be applicable to absorb the image of a file, spiral arm is rotatable usually, be beneficial to file projector and take in action, make it have the effect of the light little and easy-to-operat of overall volume, after the user operates the spiral arm rotation, and be fixed in an angle, but can't fix owing to influenced by external factor can to cause the spiral arm landing, so, common spiral arm palpus collocation one articulated mounting is so that spiral arm can be fixed on an angle.

Patent novel bulletin in Taiwan is mentioned for No. 448989 and is utilized pad, Urgent device for safety guard fences keeping vehicles on the road, pressure spring with the precompressed articulated mounting, this kind mode can make the stressed inequality that locks, and the area that locks is little and cause the abrasion of each assembly easily, so the purpose of this utility model is promptly at the device that proposes a head it off.

The model utility content

Main purpose of the present utility model is that a kind of articulated mounting of spiral arm is being provided, and makes spiral arm more smooth and easy when rotating.

Another purpose of the present utility model is to be arranged on C jacket ring seat periphery by C type shell fragment, and the strength that locks is evenly distributed on the C jacket ring seat, and then reduces other assembly abrasion.

A purpose more of the present utility model is strong and be arranged on C jacket ring seat periphery because of C type shell fragment rigidity, thus can reduce C jacket ring seat material, to reach the use that reduces cost and save the space.

In order to achieve the above object, the utility model proposes a kind of articulated mounting of spiral arm, with so that spiral arm on base, rotate, spiral arm is provided with pivotal axis, articulated mounting is installed on it, articulated mounting is to comprise a collar, one C jacket ring seat, an one C type shell fragment and a latch assembly, the collar is socketed on the pivotal axis outer surface, C jacket ring seat is arranged on the base, C jacket ring seat is in order to hold the collar, C jacket ring seat has an extending part, and a C type shell fragment is arranged on the peripheral also end of C jacket ring seat and extends to the extending part top, and latch assembly uses so that C type shell fragment and C jacket ring seat form close relation.

Beneath by the appended graphic explanation in detail of specific embodiment cooperation, when the effect that is easier to understand the purpose of this utility model, technology contents, characteristics and is reached.

Description of drawings

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is textural association figure of the present utility model.

Embodiment

The utility model provides a kind of articulated mounting of spiral arm, is arranged on C jacket ring seat periphery by C type shell fragment, and the strength that locks is evenly distributed on the C jacket ring seat, and then reduces the abrasion of other assembly.

As shown in Figures 1 and 2, it is to be respectively embodiment's three-dimensional exploded view of the present utility model and textural association figure, end in spiral arm 2 is provided with pivotal axis 42, it is in order to pivot spiral arm 2, on the pivotal axis 42 of spiral arm 2 articulated mounting 4 is set, allows spiral arm 2 be able on base 6, rotate via articulated mounting 4, and after spiral arm 2 rotations, be to be fixed in an angle, and not influenced and landing by gravitation.

Articulated mounting 4 of the present utility model is to comprise a collar 44, one C jacket ring seat 46, an one C type shell fragment 48 and a latch assembly 50, the collar 44 is to be socketed on the pivotal axis 42 of spiral arm, it is in order to bear the pressure of pivotal axis 42, C jacket ring seat 46 is arranged on the base 6, C jacket ring seat 46 is in order to hold the collar 44, C jacket ring seat 46 has integrated extending part 462, C type shell fragment 48 is arranged on C jacket ring seat 46 peripheral also ends and extends to extending part 462 tops, a latch assembly 50 is locked in extending part 462 tops in C jacket ring seat 46, in order to retaining collar 44 and C type shell fragment 48.

Wherein, C type shell fragment 48 is to be the strong material of rigidity, so, it is difficult for abrasion, C type shell fragment 48 can be a spring plate, and latch assembly 50 is to be screw, when the user locks latch assembly 50 on the extending part 462 of C jacket ring seat 46, in the time of can making C type shell fragment 48 form close relation with C jacket ring seat 46, and C type shell fragment 48 has the effectiveness of precompressed, makes locking strength and can being passed to C jacket ring seat 46 surfaces by C type shell fragment 48 of latch assembly 50, be because of C jacket ring seat 46 surface contact area big, so, lock strength and can be evenly distributed in C jacket ring seat 46 surfaces, increased the working life of the assembly in the articulated mounting, when spiral arm 2 when rotating, be because of C type shell fragment 48 has the flexible effect of regulating, institute so that spiral arm 2 rotated.

Comprehensive the above, the utility model provides a kind of articulated mounting improvement of spiral arm, be to change pad and pressure spring into a spring plate with existing articulated mounting difference, so, articulated mounting of the present utility model can be saved assembly and reach the effect of elasticity precompressed, and C type shell fragment is arranged on C jacket ring seat periphery, be difficult for causing except making the strength that locks be evenly distributed in the collar other assembly abrasion, more can be because of C type shell fragment rigidity reduce C jacket ring seat material by force, and then the use that reduces cost and save the space.

The above person; for the utility model with reference to its preferred embodiment; and represent especially and illustrate that the personage who only has the knack of this skill will be appreciated that the various changes that reach in form on the details, all can not deviate from the scope that spirit of the present utility model and claim are protected.
