Abstract
The utility model relates to a telescope regulating device with positioning and locking functions, which comprises a focus-regulating hand wheel, a hand wheel top cover, a spring, a steel ball, a gear and a connecting shaft. The hand wheel top cover is tenoned with the focus-regulating hand wheel. The spring and the steel ball are arranged inside the hand wheel top cover. The gear is fixed on the connecting shaft via screws. The spring presses the steel ball to protrude out of the hand wheel top cover and attach onto a toothed surface of the gear. The steel ball, inside the hand wheel top cover, rolls on the toothed surface of the gear, producing clear clicking sounds, so that a user of the telescope can accurately determine the regulation degree by operating the hand wheel according to the clicking sounds. After the focusing process is completed, the steel ball is clamped between two teeth of the gear under the action of the spring. If needing to focus other targets, the focus-regulating hand wheel should be rotated again with a larger force. Therefore, the device also has locking function.
Description
One, technical field:
The utility model relates to a kind of telescopical regulating device with position and lock function, belongs to the mechanical hook-up technical field.
Two background technologies:
Known regulating device, the overwhelming majority only is simple regulatory function, and regulated quantity can only be leaned on estimation, controls by self strength during use, is not easy to realize accurate adjusting; And, because of there not being lock function, having met this mechanism in the use because of carelessness and just need readjust, very inconvenient.Other has some devices also to have similar position and lock function, but because of complex structure, the part processing difficulty, cost is higher, is difficult to form batch machining.
Three, summary of the invention:
The purpose of this utility model provides a kind of telescopical regulating device with position and lock function, it produces the sound of " clatter, clatter, clatter " clearly when rolling on the flank of tooth of gear by being contained in steel ball in the handwheel loam cake, telescopical user can judge accurate regulated quantity location according to the sound when control hand wheel; After focusing was finished, because the acting force of spring, steel ball card as will be to other target focusing the time, just needs a bigger power that focusing handwheel is rotated once more between two teeth of gear, and therefore, this device also has lock function simultaneously.
The utility model is implemented by following technical scheme.Fig. 1 is that the utility model is formed the structure cut-open view, and it comprises focusing handwheel 1, handwheel loam cake 2, spring 3, steel ball 4, screw 5, gear 6 and coupling shaft 7.Handwheel loam cake 2 and focusing handwheel 1 joggle are together, spring 3 and steel ball 4 are housed in the handwheel loam cake, the handwheel loam cake symmetry that spring and steel ball are housed is installed on the both sides, axis, gear 6 is fixed on the coupling shaft 7 by screw 5, and spring 3 compressing steel balls 4 are given prominence to from handwheel loam cake 2 and are pressed onto on the flank of tooth of gear 6.
When rotating focusing handwheel, it drives spring by the handwheel loam cake and steel ball rotates together around coupling shaft, and promptly steel ball rolls on the flank of tooth of gear and produces the sound of " clatter, clatter, clatter " clearly.
Compare advantage and the good effect that the utlity model has with known technology:
Produce the sound of " clatter, clatter, clatter " clearly when 1, the steel ball of this device rolls on the flank of tooth of gear, what of regulated quantity telescopical user can judge according to the sound when control hand wheel, when using thinner gear, can realize more accurate regulated quantity;
2, after focusing is finished, because the acting force of spring, steel ball card as will be to other target focusing the time, just needs a bigger power that focusing handwheel is rotated once more between two teeth of gear, and therefore, this device also has lock function simultaneously;
3, this device mostly is the standard component formation, and simple in structure, part processing is easy, and cost is low, suitable telescopical production in enormous quantities.
Four, description of drawings:
Fig. 1 is that the utility model is formed structural drawing.1 is burnt handwheel among the figure, and 2 is the handwheel loam cake, and 3 is spring, and 4 is steel ball, and 5 is screw, and 6 is gear, and 7 is coupling shaft.
Five, embodiment:
Be described further in conjunction with Fig. 1.
The design comprises focusing handwheel 1, handwheel loam cake 2, spring 3, steel ball 4, screw 5, gear 6 and coupling shaft 7.Handwheel loam cake and focusing handwheel joggle are equipped with spring and steel ball together in the handwheel loam cake, to coupling shaft, give prominence to from the handwheel loam cake and be pressed onto on the flank of tooth of gear by spring compressing steel ball by screw retention for gear.
When rotating focusing handwheel, focusing handwheel drives spring by the handwheel loam cake and steel ball rotates together around coupling shaft, and promptly steel ball rolls on the flank of tooth of gear A, and produces the sound of " clatter, clatter, clatter ".
