Embodiment
General Principle of the present invention thereby depend on uses the hold-down screw be equipped with the sleeve pipe of being made by flexible material (for example flexible plastics), described lining to fill gap between the shell boss of screen attaching clamp and display unit.According to the present invention, when screw turns, this lining distortion, this lining is completely or partially filled the hole in the picture tube attaching clamp.Therefore, in case the location and tighten the screen hold-down screw, when shell was collided or falls, screen no longer can laterally move or it moves very limited at least.In addition, if screen moves slightly, the elasticity of lining makes screen get back to its original position, and this is different with situation about rigidly fixing.Therefore, the present invention is opposite with those skilled in the art's preconception, those skilled in the art use indeformable metal washer in the prior art, and the screen of CRT type is fixed on the shell to incite somebody to action particularly, and described packing ring prevents or limit screen laterally moving with respect to screw by friction.
In addition, the present invention makes the jack system of avoiding using shown in Fig. 1 a and 1b of outwarding winding (unscrewingsocket system) become possibility.Therefore described fixed system simple more (less components, and parts itself are more cheap) and the assembling of himself simpler (basic assembly manipulation still less).
Fig. 2 demonstration is equipped with the plastic bushing 22 of the specific embodiment according to the present invention and the screw 20 of packing ring 21.
Screw 20 is preferably metallic screw, it comprise average diameter D1 scope 10 and 14mm between head 200 and threaded bar portion 201.The outer diameter D max of threaded bar portion for example 6 and 11mm between and typically equal 7 or 10mm, corresponding to thread root diameter Dmin about 5 or 8mm.
Packing ring 21 is preferably flat, and it is folded between lining 22 and the screw head 200.More or less identical of the external diameter of the internal diameter of packing ring and bar portion 201 is so that packing ring 21 can firmly be pressed against on 200 when screw 20 is tightened and so that not have any gap or gap minimum around the hollow space king-rod portion 201 of packing ring 21.According to the modification of embodiment, the bar portion of screw does not have car to have screw thread and packing ring 21 to be positioned at this part in the part of close its head.
The material of lining 22 preferably has more than or equal to 500 and is less than or equal to poplar formula (or elasticity) modulus (this makes lining fully be out of shape and does not break according to the present invention) of 2500MPa (comprising 2500MPa) and more preferably still more than or equal to 500 and be less than or equal to 1000MPa.This yang type modulus allows lining to deform when screw turns and to any collision that may suffer with the CRT display unit and/or fall the distortion that is associated resistance is provided especially.
Packing ring 22 is made by deformable material and it can not break when tightening screw 20.Described material is preferably deformable plastic, for example polystyrene (PS), acrylonitrile-butadiene-styrene (ABS) (ABS), ABS blending of polymers, polyamide (PA), polypropylene (PP), s-B-S (SBS), have the SBS (SEBS) of the deformability dense rubber of excellent stiffness, special foaming.However, it can be any kind that can be out of shape when screw 20 is tightened with the gap around the screw in the hole that is filled in attaching clamp at least in part 20.Also more preferably, the material of use can be a polystyrene, and it is common and cheap relatively material.
Described lining preferably has column and along longitudinal axis hollow.Same and the diameter Dmin of the internal diameter of lining 22 much at one, described diameter Dmin is the root diameter (RD) of bar portion 201.The internal diameter of lining 22 for example can exceed the numerical value that diameter Dmin is less than or equal to the numerical value of 0.3mm and preferably exceeds diameter Dmin0.1mm.The thickness of lining 22 is approximately 1.25mm (therefore, if internal diameter equals 7mm, its external diameter is 9.5mm so).More generally, the thickness of lining is between 1.1mm and 1.5mm.Preferably, lining 22 has the little external diameter of internal diameter than picture tube attaching clamp mesopore, so that this lining is positioned on the body of screw 201 before screw 20 is placed on the attaching clamp.
Lining 22 can be an extruder member, or can instead be moulding part (moulding part can have a broader category of shapes).
Before screw 20 screwed in, lining 22 had length L, this length L preferably equal 25mm and more generally scope 20 and 28mm between.
At first, use proper tools (for example acting on the spanner of two opposite planar) or manually packing ring 21 is screwed on the screw 20, arrive the part that does not have screw thread up to described packing ring.
Next, lining 22 is placed in the bar portion 201.Preferably, the internal diameter of lining is greater than the minimum diameter Dmin of threaded bar portion 201, and less than maximum dimension D max, so lining 22 can be positioned on (for example by it is screwed on) on the screw 20, in case this lining is positioned, it just can not separate from described screw.
Therefore, CRT is fixed on the shell and can more easily realizes, this is because described packing ring and described lining remain on the described screw with being hunted down.In addition, it is easier that this makes the gap of filling at least in part around the screw.
In addition, in lining is screwed to embodiment in the bar portion 201 by screw thread, described lining by deformability and the material that do not rupture make, need before screwing in, not make screw thread, formation screw thread naturally when screwing in.According to some embodiment, described lining can comprise internal thread so that its easier being screwed on the screw 20.
