Abstract

The utility model provides a floating fixation device, wherein a limit hole capable of penetrating a locking component is disposed at one side wall surface of a penetration space in a sleeve, and a location part is formed at the other side of an annular projection part outside of the sleeve; a rod body capable of penetrating in the penetration space outwards extends from one side of the head of the locking component; an embedded part is formed at the connected place of the rod body and the head, and a screwing part and an elastic component are disposed at the other side of the embedded part; a resisting part capable of presenting a stop location with the annular projection part is disposed at the other side opening away from the head of an outer sleeve combined at the outside of the head; when the locking component is pressed-connected on the sleeve, the embedded part can be forced at the periphery of the limit hole to form a separated state after preset location and rotation, in order to keep the whole gravity centre stable; therefore, the combination of the location part of the sleeve and a plate is more precise, and effects of increasing the manufacturing quality and yield as well as decreasing cost are achieved.

Description

Floating type fixing device

Technical field

The utility model relates to a kind of floating type fixing device, particularly sleeve inner is provided with the spacing hole that can supply lock member to penetrate, and be formed with the embedding part that forms separated state after can presetting location, turn with spacing hole in the head of lock member institute tool and shaft joint, to reach the effectiveness that improves quality bills of materials and yield.

Background technique

General panel (plate is to plate) is when making up, utilization possesses knob is arranged, the set screw of the collar and screw gives interlocking, it is that screw, the collar are fixed on first panel, and turn makes screw lock to form in second panel and presets the location in knob, after utilizing hand tools with screw lock again, then make first panel be one, and can be used on the sheet material that machine tool or other plates connect plate and use for being fixed into the second panel interlocking.

Moreover, just develop the floating screw that this kind is made up of cap bag, screw rod and positioning seat by the dealer, after earlier the positioning seat button of floating screw being fixed in the perforation of sheet material, it is fixing to utilize screw rod to come interlocking to form on another sheet material again, and when the user unloaded sheet material, floating screw still can see through in the perforation that positioning seat is fixed in sheet material can not cause loss because of user's carelessness.

See also shown in Figure 10, side cutaway view for existing fixing device, find out by knowing among the figure, existing fixing device is to be assembled with lock-connecting piece B in sleeve A, and sleeve A outer cover is provided with elastomer A1, and be held in backstop bulge loop A2 on the sleeve A with elastomer A1 one side, the opposite side of elastomer A1 then is held in the inboard place of cap head B1 that lock-connecting piece B is had, the screw rod B2 that cap head B1 one side of lock-connecting piece B is extended penetrates the inner formed containing space A0 in sleeve A again, just can rely on backstop A3 block that sleeve A establishes in the inboard place of containing space A0 between the screw rod B2 and sleeve A of lock-connecting piece B, and the screw rod B2 that makes lock-connecting piece B passes the containing space A0 outside of sleeve A, lock in screw rod B2 again and be connected to a nut C, can be located on the sheet material D by the welding section A4 weldering that sleeve A is positioned at backstop bulge loop A2 bottom, and utilize lock-connecting piece B to come interlocking after another cooperates on sheet material, to be combined into one.

When though this kind mode can avoid sleeve A weldering to be located on the sheet material D, because the situation that the gap between sleeve A and the lock-connecting piece B produces skew or rocks, collide the wearing and tearing that the perforation (not shown) on sheet material D is derived to prevent that lock-connecting piece B interlocking from cooperating on the sheet material in another, collapse problems such as tooth, and be difficult for causing structural damage of sheet material D and destruction, only this sleeve A is incorporated into when carrying out weld job on the sheet material D, its soldering-tin layer can be infiltrated in nut C place along the micro-gap between sleeve A and the perforation because of add hot melt tin by the tin stove after, so that by forming the situation of obstruction or blocking behind the tin stove easily, allow the operating personnel when utilizing instrument that nut C is dismantled, just can produce skidding on lock-connecting piece B, inconvenience and degree of difficulty when causing nut C dismounting increase, whole spent also relative raising with cost in man-hour redesigns effectively and is solved and remain to be engaged in this journey dealer.

Designer of the present utility model is because problem and the disappearance that existing fixing device is used, so collect related data via assessing in many ways and considering, and utilize the research and development experience for many years of engaging in the industry constantly to study and revise, the model utility that the beginning is designed the floating type fixing device of this kind is born.
