Abstract
The utility model discloses a sliding sleeve formula enclosed type subassembly that does not drop, sleeve including clamp the through -hole of seting up on the panel in, sleeve interpolation are equipped with axially movable's sliding sleeve, still including running through sliding sleeve and the telescopic screw that does not drop, have cup jointed the spring on the screw that does not drop, and the spring both ends are supported respectively and tightly are in sliding sleeve and sleeve inner wall. The utility model discloses a sliding sleeve mechanism design utilizes the spring control degree of freedom of screw on X, Y, three coordinates of Z that does not drop, and utilize the sliding sleeve to seal do not drop screw irregular contour and the irregular space that the panel formed, strengthened the clean and tidy degree of panel outward appearance, and when the screw that does not drop is rotatory and the contact surface for the sleeve surface, guarantee that panel surface is not impaired.
Description
Technical field
The utility model relates to the connection part of field of machining, is specifically related to a kind of sliding bush type enclosed type and does not come off assembly.
Background technique
Releasing screw does not connect is a kind of widely used linkage structure, the particularly rack of vehicle carried type and combination stage product, there is higher reliability requirement, and the product of current this type, all directly have employed plain edition not releasing screw to carry out the fastening of rack and each combination thereof, thus bring following point:
1) due to the rotary motion in the using process of common not releasing screw, cause the finish paint of the assembled panel contacted with it seriously impaired;
2) when assembled panel surface of contact sinks, plain edition not releasing screw head is sunk thereupon, and exposed parts shortens, operating difficulties during fastening screw trip bolt;
3) plain edition not releasing screw be in free state all the time, with panel out of plumb, malalignment, affect rack appearance quality; Fastening combination is inconvenient, not quick, and very easily scratches assembled panel;
4) during combination playback, plain edition not releasing screw screw thread is easily damaged because impacting, and cabinet framework is because impacting easily damaged by screw, and working service cost is higher.
Model utility content
The utility model aims to provide a kind of sliding bush type enclosed type and not to come off assembly, sink causes the problems such as tightening operation difficulty, outward appearance irregularity and maintenance cost are high to solve impaired serious, the panel of the panel lacquer painting of tradition not existing for releasing screw linkage structure.
The utility model is achieved by following technical solution:
A kind of sliding bush type enclosed type does not come off assembly, comprise the sleeve in the through hole that is installed on and panel is offered, the sliding sleeve that can move axially is fitted with in sleeve, also comprise the not releasing screw running through sliding sleeve and sleeve, releasing screw is not socketed with spring, both ends of the spring is pushed against described sliding sleeve and sleeve lining respectively.
Described sleeve comprises the cylindrical shell of tubular, and cylinder top is provided with boss, and in cylindrical shell, middle part has cavity A, and cavity A center bottom has screw A.
Described sliding sleeve comprises the sliding sleeve body that cross section is rectangle, and sliding sleeve body center bottom has cavity B, and cavity B top has screw B.
Described sleeve bottom end edge is provided with chamfering A.
Described sliding sleeve bottom edge is provided with chamfering B.
The beneficial effects of the utility model are:
Compared with prior art, the sliding bush type enclosed type that the utility model provides does not come off assembly, and it has the following advantages:
1), when releasing screw does not rotate, assembled panel surface of contact is not impaired, guarantees assembled panel aesthetic appearance, and working service cost reduces greatly;
2) control not releasing screw in the degrees of freedom of X, Y, Z tri-on coordinate, make the fastening more convenient, quick of not releasing screw, and not easily scratch assembled panel;
3), during combination playback, the screw thread of releasing screw head and cabinet framework can not be not impaired because occurring to impact;
4) the irregular contour of releasing screw and assembled panel do not form Anomalistic space and are closed, vertical with panel all the time, strengthen assembled panel outward appearance tidiness.

Fig. 1 is long splice composition of the present utility model;
Fig. 2 is the sectional view of the utility model middle sleeve;
Fig. 3 is the sectional view of sliding sleeve in the utility model;
In figure: 1-panel, 2-sleeve, 3-sliding sleeve, 4-is releasing screw not, 5-spring, 21-cylindrical shell, 22-boss, 23-cavity A, 24-screw A, 25-chamfering A, 31-sliding sleeve body, 32-screw B, 33-cavity B, 34-chamfering B.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As Figure 1-3, the sliding bush type enclosed type that the utility model provides does not come off assembly, comprise the sleeve 2 in the through hole that is installed on and panel 1 is offered, the sliding sleeve 3 that can move axially is fitted with in sleeve 2, also comprise the not releasing screw 4 running through sliding sleeve 3 and sleeve 2, releasing screw 4 is not socketed with spring 5, spring 5 two ends are pushed against described sliding sleeve 3 and sleeve 2 inwall respectively.
Described sleeve 2 comprises the cylindrical shell 21 of tubular, and cylindrical shell 21 top is provided with boss 22, and in cylindrical shell 21, middle part has cavity A23, and cavity A23 center bottom has screw A24.
Described sliding sleeve 3 comprises the sliding sleeve body 31 that cross section is rectangle, and sliding sleeve body 31 center bottom has cavity B33, and cavity B33 top has screw B32.
Described sleeve 2 bottom edge is provided with chamfering A25.
Described sliding sleeve 3 bottom edge is provided with chamfering B34.
During use, releasing screw 4 does not move right, and sliding sleeve 3 follows movement, and spring 5 compresses, and Mobile Termination face is sleeve 2 left side, reaches fastening object; Releasing screw 4 is not moved to the left, and sliding sleeve 3 is followed and moved to left under the effect of spring 5, and spring 5 stretches, and Mobile Termination face is sleeve 2 right side, reaches and removes fastening object.For the ease of installing and moving, chamfering A25 and chamfering B34 is 45 °.It adopts slider mechanism design, utilize spring 5 to control not releasing screw 4 in the degrees of freedom of X, Y, Z tri-on coordinate.The Anomalistic space utilizing sliding sleeve 3 to enclose not releasing screw 4 irregular contour and panel 1 to be formed, strengthens the tidiness of panel 1 outward appearance; When releasing screw 4 does not rotate, surface of contact is sleeve 2 surface, and panel 1 surface is not easily damaged.
