Description

Picture tube mounting mechanism

The present invention relates to a fixture, particularly relate to one be used for compensating picture tube fixedly the space between ear and casing so that show more convenient, the rapid and certain fixture of assembling between iconoscope and casing.

Picture tube is called cathode ray tube again, is divided into color picture tube, black and white picture tube and monochrome tube, is to use making on assembling television set or the computer monitor very important components.

General picture tube can be divided into two kinds of forms again, and a kind of nothing is ear fixedly, shown in Figure 1A.Another kind then has four fixedly ears, shown in Figure 1B.See also Fig. 1 C, not having fixedly, the picture tube 11 of ear is fixed on the casing 12, use one to be equipped with the quoit ring 14 that to adjust bolt 13, add the hook 15 that four sheet metals are shaped, being used for frame lives picture tube 11, re-uses four screws 16, respectively in the corner and casing 12 lockings of picture tube 11, again with the adjustable bolt on the quoit ring 13 locking, contract eyelet grommet and force picture tube 11 tightly to be oppressed on casing 12 and fix it.

The advantage of this mode is that the unit price of picture tube is lower, but shortcoming is:

1. the fixture part of Shi Yonging is many.

2. Zhuan Pei program is many.

3. can't control the pressing degree between picture tube and casing effectively, often be not to oppress too tight and make the casing distortion, is exactly pine and picture tube is not positively fixed too.

Common have a fixedly picture tube of ear, its device that is fixed on the casing has multiple, one of them adds respectively that with four screws 22 four packing rings 23 directly pass four of picture tube 21 fixedly ears 24 and picture tube 21 is fixed on the casing 12 shown in Fig. 2 A and 2B, its advantage is: 1.Part is simple; 2. install easily.

But there is a very big shortcoming in this device.See also Fig. 3 A and 3B, because the fixedly ear 24 of picture tube is very big with the scale error of the vertical range (K) of the contact point at picture tube face and casing edge, be generally ± 2mm, but the length (H) of the reference column 26 of casing is then because be that mould is one-time formed former thereby for certain, thus often cause be not the picture tube face too packing casing 12 make casing 12 distortion, as shown in Figure 3A, be exactly that picture tube face 21 is not adjacent to casing 12, there is slot to produce, shown in Fig. 3 B, influences the quality of whole machine.As for avoiding above-mentioned shortcoming, then must earlier picture tube be selected classification, with the packing ring compensation, so then time-consuming bothersome; As require to buy the little picture tube of scale error amount, then unit price is much higher again, costs a lot of money.

They are two years old, shown in Fig. 4 A and 4B, use a screw rod 31, screw rod 31 is provided with the hold-doun nut 32 that screw thread with it is combined into one, have one can adjust packing ring 33 and have the nut 34 of packing ring in addition, four groups of the assemblies that combines, elder generation screws in an end of screw rod in the reference column 35 of casing respectively, can adjust packing ring 33 again screws in the screw rod 31, again with four of picture tube 36 fixedly ear 37 entangle screw rod 31 respectively, rotation can be adjusted packing ring 33 respectively then, makes it to prop up mutually with the bottom surface of the fixedly ear 37 of picture tube, and the nut 34 that will have packing ring is again locked screw rod 31 and picture tube is locked on the position.

The structure of this device is stronger, and can adjust effectively and compensate the scale error of picture tube and suitably adjust compressing power between picture tube and casing.But it has also that part is too many, unit price is high and shortcoming such as linkage editor is numerous and diverse.

Its three, shown in Fig. 4 C, on the L shaped supporting mass 41 slotted hole 42 is arranged, earlier these supporting mass 41 usefulness screws 43 are fixed on the casing 46, the supporting member 44 usefulness spiral shell FF silks 47 that another is L shaped are fixed on the L shaped supporting mass 41.Be adjusted to the appropriate location, again picture tube 48 locked.It can be adjusted effectively and compensate the scale error of picture tube, and can suitably adjust the compressing power between picture tube and casing.But it also has part various, the numerous and diverse and very high shortcoming of assembly cost of linkage editor.

The device of above-described various fixed picture tube, the part that is not to use is too much, the production cost height, or linkage editor is numerous and diverse, can't control the compressing power between picture tube and the casing exactly effectively, or the caused assembling of scale error that can't compensate picture tube itself effectively is bad.

Therefore, the object of the present invention is to provide a kind of picture tube mounting mechanism that can compensate scale error between picture tube and the casing standing part.

The invention provides a kind of being used for is fixed to a fixed mechanism on the fluorescence enclosure to a picture tube, and this picture tube stretches out a fixedly ear with an open-work, has a pillar mechanism that has a fixing hole on fluorescence enclosure; Also comprise a screw mechanism, the latter has screw rod and a screw cap and the head of screw with an axis, this screw rod passes the open-work on the described fixedly ear and screws in the fixing hole in the pillar mechanism, and described screw cap blocks described fixedly ear and moves to the direction away from pillar mechanism; Reach and also comprise a adjusting mechanism with a screwed hole, it is installed between described fixedly ear and the described pillar mechanism, and its screwed hole matches with screw rod, it is characterized in that, this adjusting mechanism is mounted in described pillar mechanism and can moves freely along the axis direction of described screw rod and can not relatively rotate, and adjusting mechanism is adjacent to described fixedly ear and prevents that fixedly ear moves to described pillar direction.

See also Fig. 5, picture tube mounting mechanism of the present invention includes the screw mechanism 9 in pushing and pressing washer arrangement 6, adjusting mechanism 7, pillar mechanism 8 and one or two section bar footpath, wherein pillar mechanism 8 is located at the corner of display front housing 50, there is locking hole 81 in its central authorities, preferably are provided with body 82,83 in pillar mechanism 8 both sides.Adjusting mechanism 7 slightly becomes inverted U, be located at fixedly between ear 51 lower ends and pillar mechanism 8, it is relative with the locking hole 81 of pillar mechanism 8 that its central authorities are installed with screw 71 thoroughly, and two

positioning pillars

72,73 that adjusting mechanism 7 extends protrusion are inserted and are stretched into pillar mechanism 8 both sides and hang down in the body of establishing 82,83, only can do vertical slip with restriction adjusting mechanism 7 in being inserted in body 82,83 time.

Pushing and pressing washer arrangement 6 is located at fixedly ear 51 upper ends of picture tube 5, for being different from the general strong more free machining material of steel.Pushing and pressing washer arrangement 6 thicknesss of slab are at least greater than a thread distance of screw mechanism 9, and its surface central authorities are with respect to fixing place, ear 51 holes, and formation endoporus 61 carries out the thread lock of adjusting mechanism 7 and pillar mechanism 8 to pass screw mechanism 9.The screw rod of the screw mechanism 9 of this thread lock is divided into two sections, sections bar footpath 91 is slightly larger than the endoporus 61 of pushing and pressing washer arrangement 6 on it, screw 71 thread lock of following sections bar footpath 92 threads and adjusting mechanism 7, this screw 71 is tight fit with epimere bar footpath 91, and be loose fit with the thread in following sections bar footpath 92, but screw mechanism 9 thread lock are being penetrated in the locking hole 81 of pillar mechanism 8, through screw 71 to connect picture tube 5.

Fig. 6,7 is respectively decomposing section of the present invention and combination constructed profile.Can know and find out by diagram, during with picture tube 5 locking location, will push against washer arrangement 6 earlier and be inserted on 9 times intercept bars footpaths 92 of screw mechanism, pass fixedly ear 51 again, lock the locking hole 81 that arrives pillar mechanism 8 through the screw 71 of adjusting mechanism 7.When using, as shown in Figure 7, because the endoporus 61 that the last pole footpath 91 of screw mechanism 9 is slightly larger than in the pushing and pressing washer arrangement, stayed on endoporus 61 by card, when making screw mechanism 9 turns, form the slippage of pushing and pressing washer arrangement 6 on fixing ear 51, and make screw mechanism 9 can't down bore locking.Also rely on by the mutual screw of screw mechanism 9 and adjusting mechanism 7 this moment, makes adjusting mechanism 7 upwards shift near fixedly ear 51, and allow fixedly ear 51, push against washer arrangement 6 and screw mechanism 9 offsets.Because the distance that adjusting mechanism 7 rises is decided by the fixedly ear 51 of picture tube 5 and 8 distances that differed of pillar mechanism in the display front-housing body 50, the adjusting mechanism 7 that make to rise can compensate the mismatch error of 8 in picture tube 5 and pillar mechanism, the trouble of having adjusted when having eliminated assembling effectively.

When adjusting mechanism 7 rises and its bizet when pushing against fixedly ear 51 members such as grade gradually, the fixedly frictional force between ear on pushing and pressing washer arrangement 6 and picture tube 5 sides increases gradually, can't produce slippage up to pushing and pressing washer arrangement 6, thereby when making screw mechanism 9 continue toward the backspin lock, will be as shown in Figure 8, make the thread in sections bar footpath 91 bore tapping to the adjusting mechanism 7 that pushes against washer arrangement 6 and lower end thereof, screw rod passes pushing and pressing washer arrangement 6, screw 71 through adjusting mechanism 7 arrives pillar mechanism 8, make the lead screw of screw 9 can more go deep into anchor post mechanism 8, arrive to pushing and pressing washer arrangement 6 until its screw terminal root edge, and firmly picture tube 5 is fixed on the picture tube procapsid 50.

In order to control the frictional force of 9 of washer arrangement 6 and screw mechanism effectively, so that washer arrangement 6 is blocked sections bar footpath 91 when adjusting mechanism 7 rises the bizet contact of adjusting mechanism 7 fixedly on ear 51 reliefs sections bar directly continue down tapping, washer arrangement 6 can be as shown in Figure 9 structure, approximately suitable endoporus 61 peripheries of radius with last sections bar footpath provide several juts increase with appropriateness on sections the bar directly 91 and frictional force of 6 of washer arrangement.

Figure 10 shows that another embodiment of the application, its structure is comparatively simple, and the bar of screw mechanism 173 is wherein directly fixed, and does not have two sections different bars footpaths like former screw mechanism 9, and its adjust structure two foots 163,164 have elasticity.As shown in figure 11, adjusting device is subjected to the pushing of vertical direction when assembling, makes that adjusting device 7 can rise because of the elastic force of its foot when screw mechanism 173 screws in.
