Description
Technical field
The utility model relates to a kind of height adjustable electronic installation, particularly relates to the adjustment height devices that a kind of projector uses.
Background technology
When screen was put with image projecting by projector, owing to usually be subject to the projection platform of putting projector, for example the height of desktop or levelness made the image that is projected to screen produce the phenomenon of distortion or distortion.Therefore, has height adjustable adjustment pin usually in the projector bottom, to improve the situation of image distortion or distortion.
As shown in Figure 5, be an existing projector with rotary adjustment pin.The adjustment pin 508 of this projector 500 comprise support portion 510, tooth bar 504, with teat 514.Because support portion 510 contacts with projection platform 502, and the part weight of carrying projector 500, so support portion 510 and 502 generations of projection platform, one friction force.When the user will adjust the extension elongation of pin 508, the user must provide the external force greater than this friction force, just can effectively rotate and adjust pin 508, and this measure often allows the user feel suitable effort.Moreover the user must rotate to adjust and just can rise a little behind pin 508 a lot of circles or the height of decline projector 500, and it is quite slow to regulate the speed.
Another kind is as shown in Figure 6 adjusted foot device, and it is Japanese patent application publication No. sign indicating number 11-271879.This adjusts foot device and comprises push rod 610, tooth bar 612, spring 614a and 614b.Push rod 610 is disposed in the casing 602 in the mode that can move horizontally.Push rod 610 extends a teat 610a outside casing 602, for user one application of force place, and a moving part 610b and tooth bar 612 engagements.Under state of nature, the elastic force of spring 614a forces moving part 610b and tooth bar 612 engagements, to reach the effect of firm adjustment pin 608.
Yet when the user will adjust pin 608, the user must pull push rod 610 with another then earlier with a hand support projection machine 600, and moving part 610b and tooth bar 612 are broken away from, and then, the elastic force of spring 614b is just released tooth bar 612.Person to be used decontrols push rod 610 after adjusting the height of adjusting pin 608 again, and moving part 610b and tooth bar 612 are meshed once again.So, finish the height of adjusting projector 600.
The utility model content
The purpose of this utility model is to provide a kind of height adjustable electronic installation, and this device has the adjusting gear that is exposed to the outer push button of housing, adjusts the height of electronic installation to make things convenient for the user.
The purpose of this utility model is achieved in that promptly provides a kind of height adjustable electronic installation, and this electronic installation has a housing, and this electronic installation comprises: a junction, and this connecting portion is connected with this housing, and has a guide groove and a tooth bar; One feet, this feet are installed in this guide groove movably, and selective property ground supports this electronic installation; One elastic, this bullet spare portion connects this feet; One push button, this push button connects this elastic; And a stop assembly, this tooth bar of selective property ground engagement.
After being subjected to external force pressure, push button makes the elastic bending.Therefore, stop assembly breaks away from tooth bar, makes feet move in guide groove.When external force disappears, the recovery elastic force of elastic will make elastic restore to the original state, and retainer meshes with tooth bar once again, with the position of fixed support pin.
The utility model also comprises an elastic parts, and this elastic parts connects this guide groove and this feet, for feet one elastic force, in order to this feet that resets.
Advantage of the present utility model is that it has the function that can adjust the electronic installation height, and to improve distortion or the metaboly as electronic installations such as projectors more conveniently, it is easy to adjust reliable, rational in infrastructure.

Embodiment
The utility model provides a kind of electronic installation (electronic apparatus), and utilizes an adjusting gear (adjusting apparatus) to adjust the height of this electronic installation.See also Fig. 1, Fig. 1 is the synoptic diagram of the utility model first embodiment.Adjusting gear 200 is located on the electronic installation 100.This electronic installation 100 comprises a housing 101.Adjusting gear 200 connects the surface of the housing (shell) 101 of electronic installation 100.This electronic installation 100 is a projector.
See also Fig. 2 a, Fig. 2 a is the stereographic map of adjusting gear 200.Adjusting gear 200 comprise a junction (connecting device) 201, one feet (leg) 207, a push button (push button) 209, one extension (extending part) 215, one elastic (elastic part) 211, with a retainer (stopper) 213.This connecting portion 201 connects the housing 101 of this electronic installation, and comprises a guide groove (groove) 203 and a tooth bar (rack) 205.Feet 207 is to be installed in the guide groove 203 selective property ground support electronics 100 movably.Elastic 211 connects feet 207.Retainer 213 and tooth bar 205 engagements are for the extension elongation of fixed support pin 207.Push button 209 is connected with elastic 211 by extension 215, for the application of force place of external force.
See also Fig. 2 b, Fig. 2 b is the side sectional view of adjusting gear.Push button 209 is subjected to oppress elastic 211 after the external force, further makes elastic 211 bendings.Therefore, retainer 213 breaks away from tooth bar 205, and feet 207 is moved in guide groove 203.Be noted that in the height process of adjusting electronic installation 100, the degree of depth that the user is pressed into push button 209 need make retainer 213 break away from tooth bar 205 fully, feet 207 is moved smoothly.
Yet when external force disappears, the recovery elastic force of elastic 211 will make elastic 211 restore to the original state, shown in Fig. 2 a.Therefore, retainer 213 meshes with tooth bar 205 once again, and the position of fixed support pin 207.
Generally speaking, this adjusting gear 200 is connected in the position of housing 101, can be on demand and different.As shown in Figure 1, this electronic installation 100 is a projector, so adjusting gear 200 is installed on the place ahead housing 101 of this electronic installation 100.In addition, use adjusting gear 200 for making things convenient for the user, the button 209 of adjusting gear 200 is exposed to outside the housing 101.
See also Fig. 3, Fig. 3 is the adjusting gear synoptic diagram of the utility model second embodiment.Adjusting gear 300 comprises a junction 301, a guide groove 303, a tooth bar 305, a feet 307, a push button 309, an extension 315, an elastic 311 and a stop assembly 313.Different with first embodiment is that the design of tooth bar 305 has become bilateral tooth bar by monolateral tooth bar.In addition.Stop assembly 313 also need cooperate the change of tooth bar 305, need be designed to mesh simultaneously the tooth bar on both sides.
See also Fig. 4 a and Fig. 4 b, Fig. 4 a and Fig. 4 b be the utility model the 3rd embodiment adjusting gear just, side view.Adjusting gear 400 comprises a junction 401, a guide groove 403, a tooth bar 405, a feet 407, a push button 409, an elastic 411, a stop assembly 413 and an elastic parts 417.Different with previous embodiment is to have lacked extension 215,315, and push button 409 directly is connected with elastic 411.Therefore, the transverse width of push button 409 needs the transverse width less than aforementioned push button 209,309, so, just can be pressed into push button 409, makes stop assembly 413 break away from tooth bar 405.In addition, elastic parts 417 connects this guide groove 403 and this feet 407, can provide support the elastic force that pin 407 1 upwards improves, and returns to original position in order to help feet 407.
