Description

Computer rotation shaft

The utility model is about a kind of computer rotation shaft, particularly establishes stube cable about in a kind of, and rotatable radian is big and be convenient to be assembled in computer rotation shaft on the information products main body pedestal.

Development along with audio frequency and video technique, on various information products, computer rotation shaft is used widely for the demand that adapts to the multimedia function expansion, the application of rotating shaft in information products be two parts of link information product normally, LCD part and pedestal as notebook computer, the volume of this product is reduced, so that carry or place.

It is multiple that existing rotating shaft constitutes spring pivot structure, bolster elastic piece structure etc., as shown in Figure 1, a kind of rotating shaft that can arbitrarily locate that is used on the notebook computer that is disclosed for No. 81201626 for the Taiwan patented claim, it by turning axle 1, pad 2, bolster 3, dish type shell fragment 4, sleeve 5, spring 6, location-plate 7, end loose nut 8 etc. and form, provide suitable elasticity with the dish type shell fragment 4 of reverse setting.Though this structure can realize pivoting and positioning function, but turning axle 1, bolster 3 complexity such as component construction such as grade, processing and manufacturing cost height, the total composed component is many, two pads 2 are arranged at the both sides of bolster 3 during assembling, turning axle 1 passes pad 2 successively, bolster 3, dish type shell fragment 4, sleeve 5, spring 6, the axis hole of location-plate 7, spring 6 is set in sleeve 5 surfaces, end hook places the spring dog hole of being offered on bolster 3 Extendible flakes before the spring 6, spring 6 is blocked in the L shaped outside that location-plate 7 bottoms are extended inwardly, location-plate 7 outsides are then sealed with above-mentioned each element with ending loose nut 8, its process is loaded down with trivial details time-consuming, and production efficiency is low; In addition, be subject to the structure of bolster 3, this rotating shaft can only be used for certain products, and can't the power supply source line in the turning axle 1 or signal wire pass through.

At above-mentioned shortcoming, the computer rotation shaft that another kind is applied to notebook computer to this in addition improvement, its composed component is less, cable can be set pass through wherein in computer rotation shaft, to provide electric connection between display screen and matrix.As shown in Figure 2, be United States Patent (USP) the 5th, 566, the computer rotation shaft that is disclosed for No. 048, it is made up of engaging arms 38, spring isolator 46, spring 60, shaft coupling mechanism 100, friction axle bush 126 etc., and after the computer rotation shaft combination, a soft cable 140 passes the hollow pipeline of above-mentioned each element successively, this cable 140 can be used to transmit electric signal from body portion to show ontology, to reach the purpose that electrically connects body portion and show ontology.But this computer rotation shaft is still comparatively complicated, is difficult for assembling, and opens or when closing display screen, spring 60 circumferencial directions rotate and produce different torsional moments, and angle rotatable is limited in 150 degree.So, must provide a kind of new computer rotation shaft to solve the above-mentioned various shortcoming that exists at the shortcoming of above-mentioned every prior art.

The purpose of this utility model provides a kind of simple in structure, computer rotation shaft of being convenient to load and unload.

Another purpose of the present utility model provides establishes stube cable in a kind of, can electrically connect the computer rotation shaft of auxiliary device and main equipment.

The purpose of this utility model is achieved through the following technical solutions: this computer rotation shaft mainly comprises a fixed muffle, one rotating element, one spring and one is connected sleeve, the top formed projection shape trip of this rotating element one end wherein, be connected the sleeve madial wall and form a groove and a circular retaining piece, this rotating element has an end of trip to be socketed in the linking sleeve, trip on the rotating element is sticked in and is connected the sleeve corresponding grooves, the other end then is sheathed in the fixed muffle, and spring then is installed between above-mentioned rotating element and the block element.

By technique scheme, the radian rotation greatly of the utility model computer rotation shaft, be convenient to loading and unloading, and can in this computer rotation shaft, pass a stube cable between the main body pedestal of these information products and auxiliary device, to provide electric connection.

Fig. 9 is the stereographic map of the utility model computer rotation shaft after assembling on the LCDs PC is finished.

Please together with reference to Fig. 3 and Fig. 6, the utility model computer rotation shaft can be used on the LCDs PC (LCD PC), this computer mainly is made up of main body pedestal 80, attached housing 90, computer rotation shaft 100 and loudspeaker 110 etc., and wherein attached housing 90 is pivoted on the main body pedestal 80 with computer rotation shaft 100.The fixed muffle 10 of computer rotation shaft 100 is integrally formed in the relative both sides of LCDs on the main body pedestal 80, and attached housing 90 is made up of loam cake 60 and lower cover 70, and loudspeaker 110 can be placed in the receiving space of loam cake 60.

Please refer to Fig. 4 and Fig. 5, further offer aperture 12 on fixed muffle 10 madial walls, computer rotation shaft 100 comprises rotation axis 20 in addition, spring 30, stube cable 40 and linking sleeve 50, rotation axis 20 external diameters are slightly littler than the internal diameter of fixed muffle 10, it axially is a hollow pipeline 26, can pass stube cable 40, the one end becomes an inclination fillet 28, the other end radially forms a stopping surface 24, the integrally formed projection shape trip 22 in top, be connected sleeve 50 firsts 52 and to be connected sleeve 50 second portions 54 integrally formed with loam cake 60 and lower cover 70 respectively, wherein be connected sleeve 50 firsts 52 with rotation axis 20 on trip 22 opposite position places form a groove 53, first and second part 52 that is connected

sleeve

50,54 respectively form a thin-walled semicircular retaining piece 56 in 53 times a distance of groove, be connected sleeve 50 second portions 54 and form a breach 58 in 56 times appropriate positions of this retaining piece, can allow stube cable 40 stretch out, after linking sleeve 50 firsts 52 close up with second portion 54, cable 40 is passed; Spring 30 can be freely flexible between the stopping surface 24 of rotation axis 20 and the retaining piece 56 that is connected sleeve 50.

Please refer to Fig. 6 and Fig. 7 again, earlier loam cake 60 is overturn during assembling, loudspeaker 110 is contained in the receiving space of loam cake 60, rotation axis 20, spring 30 and stube cable 40 are assembled in the two ends that are connected sleeve 50 firsts 52 in regular turn, projection shape trip 22 on the rotation axis 20 is sticked in corresponding groove 53 in aforementioned linking sleeve 50 firsts 52, between the stopping surface 24 that spring 30 is compressed in rotation axis 20 and the retaining piece 56 that is connected sleeve 50 firsts 52, stube cable 40 passes rotation axis 20 successively, spring 30, ring-type retaining piece 56 passes the breach 58 that is connected sleeve 50 firsts 52 again and electrically connects with loudspeaker 110.Lower cover 70 is closed in loam cake 60 again and form attached housing 90, be connected sleeve 50 firsts 52 and be connected together mutually with second portion 54, the attached housing 90 after the combination as shown in Figure 7.
