Description
Technical field
The utility model relates to the manual rackwork between a kind of hinged two parts, and the upper body that can make between particularly a kind of upper body that is hinged on negative ion generating device and the lower case is pivoted and the rotary positioning apparatus of self-locking at an arbitrary position within the limits prescribed.
Background technique
At present, the rotary positioning apparatus great majority that are hinged between two parts adopt elastic element as the positioning locking mechanism.But because the frayed and influence of mounting accuracy of elastic element will produce the defective that the locking of positioning back was lost efficacy in use between two parts.The housing of existing negative ion generator and the structural type of the rotary positioning apparatus between the base mainly contain following several: be to be the structure that adopts axis hole to cooperate between housing in " the high-performance bio negative ion therapeutic equipment " of CN2606478Y and the base as notification number, and the defective that its existence can only left-right rotation can not be rotated up and down.Notification number is to be to adopt nut check between CN200958053Y's base in " a kind of negative ion generator " and the bonnet, and there is the uncontrollable defective of degree of tightness in it.Notification number is that CN2681414Y's leg and the shaft joint in " a kind of negative ion generator " adopts rubber cushion as the locking regulating element, and there is the little defective of scope of regulating in it.Notification number is that CN200993297Y's rotation positioning tube and the main body locating support in " angle limits rotary positioning mechanism " is to adopt elastic element, and there is the long-term defective of using positioning locking to lose efficacy in it.
The model utility content
The purpose of this utility model provides that a kind of to be used for manual adjustment arbitrarily angled, and the rotary positioning apparatus of arbitrary position self-locking within the limits prescribed, can overcome the defective of the long-term use positioning locking inefficacy of existing apparatus existence effectively, it is reasonable in design, compact structure, easy to adjust, locking and positioning is reliable, long-term use was not lost efficacy, and can increase the overall appearance aesthetic feeling of equipment.
The purpose of this utility model be achieved in that this device comprise back cover by the hinged upper body of the back shaft that has thumb wheel and lower case before, rear column, it is characterized in that: before described back shaft is supported on, in the split type circular hole of rear column, the thread rotary orientation that is arranged on described back shaft two ends is opposite, and be assembled with respectively thereon periphery be provided with along before, the left side of the guiding feather key that the guide rail of rear column inner chamber vertically moves, right nut, on a left side, be assembled with flexible glue pad and the locking block that matches with its cross section in the taper type groove of right nut outer end, insert the lock pad that is installed in the back cover square opening in the square groove of locking block, and utilize lock bolt that lock pad and locking block and back cover are linked together.
Be arranged on the rotary stopper mechanism that rotates in the rotational angle range of regulation on the described front column, and the limiting block that matches with rotary stopper mechanism is set on locking block.
Because the utility model adopts the thread rotary orientation at the back shaft two ends that have thumb wheel opposite, so assembling left and right nut thereon can longitudinally move back and forth by feather key on each nut 12 and forward and backward column upper rail simultaneously, and match with flexible glue pad and locking block in being assembled in left and right nut frustum connected in star, the realization manual adjustment is arbitrarily angled, arbitrary position self-locking within the limits prescribed.It adopts rubber pad as the locking regulating element, the wide ranges of regulating, reasonable in design, compact structure, influence to appearance and modeling is very little, and rotation angle is easy to adjust, and locking and positioning is reliable, therefore long-term use was not lost efficacy, and the defective that lost efficacy is locked in the long-term use positioning that can overcome the existing apparatus existence effectively.Can increase simultaneously the overall appearance aesthetic feeling of equipment.
