Abstract
The utility model relates to a self-positioning expanded connecting sleeve between plate-shaped parts, which is provided with a head (1), a neck (2) and a back end part (3), wherein the cross sections of the head (1) and the neck (2) are of a polygon; the back end part is of a circular shape; the neck (2) is a cone of which the front end is small in the axial direction; the outer diameter of the head (1) is larger than the outer diameter of the front end of the neck (2); the end surface of the back end part (3) is provided with a counterbore; a tapered through hole with small front end is arranged between the bottom of the counterbore and the end surface of the head (1); the head (1) and the neck (2) are uniformly divided into 3 blocks to 6 blocks in the circumferential direction. The utility model causes the connecting operation between two plate-shaped parts to be more convenient, has the advantages of reliable connection and convenient installation and disassembly, can reduce cost and causes the plate-shaped parts to have beautiful appearances.
Description
Technical field
The utility model relates to the connector element between two parts, especially the connector element between plate parts.
Background technique
At present, when the surface covering parts of assembling motorcycle, electric bicycle, clamp nut 10 and bolt 11 ways of connecting (as Fig. 1) are adopted in connection between the two boards shape part usually, though this Placement has join strength preferably, but need to design connection journal stirrup 8a on a plate parts 8 therein, need snap in the U-shaped card base 10a of clamp nut 10 connecting journal stirrup 8a during installation, structure is complicated, can increase mould manufacture difficulty and cost, and the operating space that needs when installing is big, if assembly space is narrow and small, just make assembling work become difficult.Direct in addition in addition use card falcon 12 carries out clamping, card falcon 12 is made of one (as Fig. 2) with plate parts 9 wherein, and this Placement can only be used for the smoothness of control connection plate parts 8 and 9 as a kind of complementary connection usually, the assurance seam is even, but join strength is not enough.
The model utility content
The purpose of this utility model provides a kind of easy-to-operat, connects reliably, mounts and dismounts all self-positioning expansion adapter sleeve very easily.
For this reason, self-positioning expansion adapter sleeve described in the utility model has head, neck and rearward end, wherein head and neck cross section are polygonal, rearward end is circular, and neck is the little taper of front end in the axial direction, and head outer diameter is greater than neck front end external diameter, and the end face of rearward end is provided with counterbore, be provided with the little conical through-hole of front end between counterbore bottom and head end, head and neck upwards evenly are divided into 3～6 by radial groove in week.
Head and neck cross section are polygonal in the utility model, be preferably the regular polygon on 3～6 limits, attachment hole on two plate parts also is set to corresponding and the polygonal hole identical with head size, thereby connecting sleeve relatively rotates in attachment hole when preventing to assemble.Because connecting sleeve head and neck upwards evenly are divided into 3～6 by radial groove in week, make the head of connecting sleeve and neck have elasticity, can easily insert the attachment hole on two plate parts after header suppression diminishes.Screw in tapping screw then in conical through-hole, head and neck are extruded distortion, after the neck deformation with plate parts on the attachment hole inwall fit the location of finishing substantially horizontal between two plate parts.Simultaneously, with rearward end two plate parts are compressed in Vertical direction after the head dilatancy, connecting sleeve can not come off from attachment hole.During dismounting, screw out tapping screw, the head of connecting sleeve and neck resilience are shunk, thereby can take out from attachment hole smoothly.
The beneficial effects of the utility model are: make the attended operation between two plate parts convenient, connect reliably, mount and dismount all easily, and can reduce cost, make beautiful shape.

Embodiment
Extremely shown in Figure 7 as Fig. 3, self-positioning expansion adapter sleeve described in the utility model has head 1, neck 2 and rearward end 3, wherein head 1 and neck 2 cross sections are square, rearward end 3 is circular, and neck 2 is the little taper of front end in the axial direction, and head 1 external diameter is greater than neck 2 front end external diameters, and the end face of rearward end 3 is provided with counterbore 4, be provided with the little conical through-hole of front end 5 between counterbore 4 bottoms and head 1 end face, head 1 and neck 2 upwards evenly are divided into four by radial groove 6 in week.
In conjunction with Fig. 6 and Fig. 7 as can be seen: radial groove 6 runs through the end face of counterbore 4 bottoms and head 1 in the axial direction, and the part that is positioned at rearward end 3 is a straight trough, the part that is positioned at head 1 and neck 2 is the little cone tank of front end, the part that radial groove 6 is positioned at head 1 and neck 2 outer end diametrically is an enlarging shape, enlarging is rectangular, the demoulding when being convenient to moulding.
The cross section of head 1 and neck 2 also can be made equilateral triangle, regular pentagon or regular hexagon.
Referring to Fig. 8, during installation head 1 aimed at and inserts the square attachment hole on two plate parts 8 and 9, in conical through-hole 5, screw in tapping screw 7 then, head 1 and neck 2 are extruded distortion, attachment hole inwall on neck 2 distortion backs and plate parts 8 and 9 is fitted, finish the location of substantially horizontal between two plate parts 8 and 9, with rearward end 3 two plate parts 8 and 9 are compressed in Vertical direction after head 1 dilatancy, connecting sleeve can not come off from attachment hole.During dismounting, screw out tapping screw 7, the head 1 of connecting sleeve and neck 2 resiliences are shunk, thereby can take out from attachment hole smoothly, and are convenient, fast.
