Abstract
A bed pitch-angle-adjustable support for a portable computer is mainly composed of a base, a stand column and a computer clamping and holding frame. A pitch rotation rack is arranged between the stand column and the computer clamping and holding frame and provided with a horizontally-arranged transverse shaft and a ratchet wheel which takes the transverse shaft as the axis; a pawl is correspondingly arranged on the stand column. During upward pitch adjustment of the pitch rotation rack, the ratchet wheel rotates to press the pawl to move away to achieve releasing, and during downward pitch adjustment of the pitch rotation rack, the ratchet wheel and the pawl are in a stopped state, so that a user needs to open the pawl to release the ratchet wheel to rotate to a downward pitch direction. According to the structure of the pitch rotation rack, the ratchet wheel taking the transverse shaft as the axis is a quadrant ratchet wheel body, the main body of the ratchet wheel is arranged under the transverse shaft, and a clamping and holding frame shaft sleeve is arranged by taking a line crossed with the axial line of the transverse shaft as the axis.
Description
Technical field
The utility model belongs to the facility of the auxiliary use of telecommunication products, particularly the temporary fixed setting of laptop computer.
Background technique
Technological scheme by 201310030689.8 finds mechanically actuated keyboard to erect to arrange to also have afterwards structure to need to improve in force.
Summary of the invention
The support of bowing, face upward inclination angle adjustable on laptop computer bed, mainly consists of base (1), column (2) computer holding frame (3).Between column (2) and computer holding frame (3), a pitch rotation frame (4) is set.Pitch rotation frame (4) is provided with the ratchet (6) that the transverse axis (5) that horizontal cross arranges and the transverse axis (5) of take are axle center, in order to reach in controlled range to realize, face upward the use function of verting and changing, by ratchet (6) be arranged to one only have quarter turn ratchet wheel body; The main body of ratchet (6) is arranged on the below of transverse axis (5); Get that to make holding frame axle sleeve (7A) axial with the alignment of the axial line cross of transverse axis (5), the main body of avoiding ratchet (6) arranges the holding frame axle sleeve (7A) of setting-in computer holding frame (3), in order to allow transverse axis (5) install the metal concentric shafts of perforation additional, the axle center of the holding frame axle sleeve (7A) with transverse axis (5) cross is upwards promoted to the perforation obstacle that dislocation can avoid shaft axis to overlap.At the horizontal cross setting in the top of column (2) axle bed (2-5A) corresponding with transverse axis (5); From the centre at the top of column (2), offer downwards and hold ratchet (6) and make the rotational lock groove (2-1) that stops holding frame (3) to rotate, form the both sides that axle bed (2-5A) minute is located at rotational lock groove (2-1).During installation, the transverse axis of pitch rotation frame (4) (5) is packed into corresponding axle bed lid (2-5B) is closed after the axle bed (2-5A) of column (2) can be solid on column (2) by pitch rotation frame (4) code.The ratchet (8) corresponding with ratchet (6) is arranged on column (2).When pitch rotation frame (4) is faced upward adjusting, the ratchet (8) of ratchet (6) rotation compressing incision ratchets (6) exits automatic clearance ratchet (6), when will bow the incline ratchet (8) of cutting ratchet (6) while regulating of pitch rotation frame (4), support ratchet (6) and be in non-rotatable jam state, must open ratchet (8) direction of could clearance ratchet (6) inclining to bowing and rotate.Holding frame axle sleeve (7A) is the axis hole of a perforation, in order to ensure that holding frame (3) obtains stable controlling, the axial dimension of holding frame axle sleeve (7A) is extended as far as possible, can be set to 100 millimeters and control above better effects if.Computer holding frame (3) is provided with joining shaft (7), corresponding with the length of holding frame axle sleeve (7A), and the length setting of joining shaft (7) is greater than 90 millimeters.The joining shaft of computer holding frame (3) (7) is embedded to the holding frame axle sleeve (7A) on pitch rotation frame (4), load onto rotation lock (9).When computer holding frame (3) is in while bowing the inclination maximum inclining, computer holding frame (3) be take joining shaft (7) and can the right and left in the restriction of location as axle center be rotated to adapt to and while lying on one's side, adjust the parallel of picture and binocular visual angle.Because the foot rest of base stretches out setting with the direction of setting, can only support directed load.When loading onto the computer holding frame (3) of computer and face upward the moving fore side that makes keyboard that verts and approach level, very natural will operation exerted pressure; And holding frame (3) is upper as a serious gravity eccentricity structure of the joining shaft (7) of center of rotation formation relative to the center of gravity of the computor-keyboard being held, if can rotate, eccentric structure just migrates out with the center of gravity of computer the Gravity support scope that foot rest is set, and not exerting pressure all can be because of the unbalance overturning of conducting oneself with dignity.In order to prevent that this unbalance overturning from producing, must make to face upward the computer holding frame (3) while turning to several angle that inclines and enter the state that can not rotate.At the afterbody of joining shaft (7), rotation lock (9) being set can solve.When joining shaft (7) is in horizontal position, rotation lock (9) is not subject to the restriction computer holding frame (3) of rotational lock groove (2-1) can left-right rotation, computer holding frame (3) need to be faced upward to vert and must first the computer holding frame (3) that is parked in left or right be gone back to center rotation lock (9) when moving and just can enter rotational lock groove (2-1), when transverse axis (5) rotates 45 rotation locks while spending (9), entered rotational lock groove (2-1), computer holding frame (3) can not be rotated by locking restriction.
The adjustable support of bowing, face upward inclination angle on laptop computer bed of the present utility model, load onto can make laptop computer face upward after laptop computer to incline, bow incline, the using effect of left-handed, dextrorotation, face upward while inclining maximum angle, can seat operation; Selection bow incline can recumbency in the right and left operation of changing sides.
Accompanying drawing explanation
Fig. 1 the utility model embodiment loads onto computer and is in the bow left view of inclination angle state of maximum;
Fig. 2 the utility model embodiment loads onto computer and is in the right elevation that maximum is faced upward inclination angle state;
Fig. 3 the present embodiment main member decomposes the loose minute view of the axle side of showing.
Embodiment
As Figure 1-3, the present embodiment mainly consists of base (1), column (2) computer holding frame (3), between column (2) and computer holding frame (3), a pitch rotation frame (4) is set.Pitch rotation frame (4) is provided with horizontally disposed transverse axis (5) and take the ratchet (6) that transverse axis (5) is axle center, corresponding ratchet (8) is located on column (2), when pitch rotation frame (4) is faced upward adjusting, ratchet (6) rotates compressing ratchet (8) and backs out clearance, when will bow incline ratchet (6) while regulating, ratchet (8) of pitch rotation frame (4) is in jam state, must open ratchet (8) direction of could clearance ratchet (6) inclining to bowing and rotate.Textural at pitch rotation frame (4), the ratchet (6) that the transverse axis (5) of take is axle center is a ratchet wheel body of 1/4 that only has circumference, the main body of ratchet (6) is arranged on the below of transverse axis (5), gets with the alignment of the axial line cross of transverse axis (5) holding frame axle sleeve (7A) is axially set.Computer holding frame (3) is provided with joining shaft (7), and the length of joining shaft (7) is greater than 90 millimeters.Column (2) is provided with rotational lock groove (2-1), and holding frame (3) is provided with rotation lock (9).
