Abstract

The utility model relates to an elevation height regulator structure, particularly the improvement of the elevation height regulator structure used for a projector. The structure of the utility model is mainly formed by that a screw rod, a group of screw caps and a spring piece are combined, wherein the screw rod has three threads and a lower part is provided with a foot pad. A group of folding screw caps and the spring piece are used for controlling rotary fall height, the screw caps are folded up and down, and a lower screw cap is fixedly arranged on a machine body, but an upper screw cap can be butted and stopped by the spring piece. The spring piece is in an inverse S shape and has return elasticity, a touching and pressing connecting rod bunts and stops an upper swing and the spring piece can be used for pushing off a lower swing which originally correspondingly bunts and stops the upper screw cap along a shaft center. Thereby, an elevation height needed by the projector is adjusted easily by most economical cost and a most convenient operation method provided by the utility model.

Description

Elevation adjuster structure

Technical field

The utility model relates to a kind of elevation adjuster structure, refers to especially under a kind of improvement of the elevation adjuster structure that is applied to projector.

Background technology

The elevation angle adjuster that is usually used in front end two side bottoms of desktop projector or slide projector, has plenty of mode with manual rotary screw, reach required working depth, but because of when adjusting the height of a side, unbalanced state takes place in the height of side immediately in addition, and the time of therefore need spending more is in the adjustment of its height, and be to dial with finger to be rotated with the nut edge that is connected to the screw rod lower end when adjusting, very inconvenient, but do not have better method to provide yet, therefore become its structural defective.

Dial as above-mentioned employing finger and to revolve nut, with the structure of adjusting its elevation defective already to some extent, on market, occur in addition subsequently with automatic whereabouts socle, the structure that engages its socle again is its substitute, though needn't adjust the height of both sides balance in the use one by one and comparatively convenient, but higher relatively because of the manufacturing cost that engages required mechanical box structure, still do not have economic benefit.

The utility model content

The purpose of this utility model is to provide a kind of elevation adjuster structure, can adjust its elevation angle easily.

For achieving the above object, the elevation adjuster structure that the utility model provides, mainly by a screw rod, one group of nut and shell fragment combination become according to its structure;

This screw rod belongs to the screw rod of three start screw, has a foot pad, and by one group of superimposed nut and shell fragment, to control its height of whirlpooling down;

This group of nut goes to upper and lower superimposed, and following nut is fixedly arranged on the fuselage, but upper cap nut then can only be supported by shell fragment;

This shell fragment is anti-S shape, and the tool elasticity recovery presses connecting rod with one and supports and to terminate in pendulum, and can follow its axle center and push away former in the bottom that terminates in upper cap nut relatively.

By enforcement of the present utility model, can be with most economical cost, the method for operating of most convenient, and adjust the required elevation of projector easily.

Description of drawings

Fig. 1 is the work synoptic diagram of projector.

Fig. 2 is the structural representation of the utility model elevation adjuster.

Fig. 3 looks synoptic diagram on the part of screw rod.

Embodiment

See also the work synoptic diagram of Fig. 1 for projector, wherein the projection source 11 of the projector 10 of this desktop is taked a suitable elevation angle highly usually, and is located at the screw rod (socle) 12 at front bottom end two ends for adjusting and supporting by one.

See also the structural representation of Fig. 2 for the utility model elevation adjuster, wherein in each latent elevation adjuster 13 that is equipped with of fuselage front bottom end two side ends inside of this projector 10, and comply with its structure mainly by a screw rod 12, one group of nut 15,16 and a shell fragment 17 combinations become, wherein this screw rod 12 is the screw rod of three start screw (it is promptly bright that Fig. 3 is consulted in cooperation), have a foot pad 18, and by one group of superimposed nut 15,16 and shell fragment 17, to control its height of whirlpooling down.

Continue to consult Fig. 2, wherein this one group of nut 15,16 is superimposed up and down, and following nut 16 is fixedly arranged on the fuselage, but 15 of upper cap nuts can only be supported by shell fragment 17.

Still see also Fig. 2, wherein this shell fragment 17 is anti-S shape, and itself has elasticity recovery, as the clip commonly used in its 19 places, axle center inner lane be wound with returning spring (this figure is not shown); And this shell fragment 17 removes and is combined with one and presses connecting rod 20 and terminate in pendulum 21 for supporting, but and the loop axis heart 19 former to push away relatively to the bottom 22 that terminates in upper cap nut 15.

See also Fig. 3 again and look synoptic diagram on the part of screw rod, wherein this screw rod 12 adopts the three start screw design, meaning promptly increases nut helical pitch and suitable landslide degree, can freely whirlpool down and not need external force to revolve when making screw rod 12 bottom emptying and execute, but adopt superimposed two nuts 15, the design of 16 (promptly bright) in conjunction with Fig. 2, the bottom 22 that is this shell fragment 17 is when when terminating in the wing angle 23 of upper cap nut 15, promptly because of the multiplication of friction force, and stop to continue to whirlpool down, so, to control the required height in the elevation angle easily, but need only the front end of mentioning projector 10 with both hands slightly, can adjust its height by nature, must will press connecting rod 20 when mentioning presses, and after treating that screw rod 12 props up desktop, loosen again, can finish the height at the required elevation angle; Otherwise, when desire is replied the horizontality of original fuselage, pressing connecting rod 20 as long as depress again, can finish.

As the structure that above-mentioned the utility model adopted, belong to a kind of natural application, when upper cap nut 15 if when being in relaxation state, still only belong to the coefficient of single nut with the friction factor of this screw rod 12, but if when being controlled, promptly it is wiped coefficient and is difficult to glide the screw rod situation of an identical general screw thread or two screw threads because of multiplication rubs, unless the external force of imposing, otherwise transfixion.

Claims

1, a kind of elevation adjuster structure, mainly by a screw rod, one group of nut and shell fragment combination become, and it is characterized in that according to its structure:

This screw rod is the screw rod of three start screw, has a foot pad, and controls its height of whirlpooling down by one group of superimposed nut and shell fragment;

This group of nut goes to upper and lower superimposed, and following nut is fixedly arranged on the fuselage, and upper cap nut is supported by shell fragment and ends;

This shell fragment is anti-S shape, the tool elasticity recovery, and one presses connecting rod supports and to terminate in pendulum, and can follow its axle center and push away former in the bottom that terminates in upper cap nut relatively.
