In order more clearly to understand above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.
Set forth in the following description a lot of details so that fully understand the present invention, still, the present invention can also adopt other to be different from other modes described here and implement, and therefore, the present invention is not limited to the restriction of following public specific embodiment.
Below in conjunction with drawings and Examples, the present invention will be further described.It should be noted that, in the situation that not conflicting, the application's embodiment and the feature in embodiment can combine mutually.
Fig. 1 is the structural representation of coupling according to an embodiment of the invention; Fig. 2 is explosive view when coupling is used in Fig. 1; Fig. 3 looks schematic diagram according to the master after cover plate embodiment illustrated in fig. 2 and support connection; Fig. 4 is that schematic diagram is looked on the left side after cover plate embodiment illustrated in fig. 3 and support connect.
The invention provides the connecting structure of a kind of support and cover plate, comprise cover plate 01, support 02 and bolt 04, cover plate 01 is provided with the first through hole 011, support 02 is provided with the second through hole 021, the connecting structure of support and cover plate also comprises coupling 03, and cover plate 01 is placed from top to bottom with support 02, coupling 03.
On body 031, run through and be provided with 032, bolt 04 coordinates with nut 05 with after third through-hole 032 through the first through hole 011, the second through hole 021 successively, for cover plate 01 is fixedly connected with support 02; The first protruding structure 033 forms to downward-extension from the relative two end part of body 031, rotating relative to body 031 while rotating with bolt 04 in order to limit nut 05; The second protruding structure 034 extends upward and forms from the relative another two end part of body 031, and the second protruding structure 034 can stretch in the second through hole 021, in order to limit coupling 03, with bolt 04, rotates.
It should be noted that, the coupling 03 described in the present embodiment obviously can also be applied in other connecting structure, and it is the displacement that is equal to of the present invention that coupling 03 is applied in other connecting structure, within should belonging to protection scope of the present invention.
When cover plate 01 and support 02 connection can form sealing or semi-closed structure and cause one side of cover plate 01 or support 02 to encounter, be just not suitable for directly with bolt, being fixed.Now can use coupling 03, the usage mode of coupling 03 can be for example:
When design cover plate 01 and support 02, make the less of cover plate 01 in outside, make the first through hole 011 can be through the screw rod of bolt 04 but can not be through the head of bolt 04, to use 04 pair of cover plate 01 of bolt and support 02 to be fixed; Making the second through hole 021 of the support 02 of the inner side in encountering is elongated hole, the width of the second through hole 021 is slightly larger than the width of coupling 03 and is less than the length of coupling 03, and the length of the second through hole 021 is greater than the length of coupling 03, make coupling 03 can pass the second through hole 021, but cannot wear back again the second through hole 021 after coupling 03 rotation, thereby coupling 03 is blocked, cover plate 01 and support 02 are fixed.
In addition, the second protruding structure 034 is wanted can snap in the second through hole 021, and the surface of contact of the second protruding structure 034 and the second through hole 021 inwall need to be relatively large plane, so just can realize the rotation that limits body 031; The first 033 of protruding structure can hold next nut 05, and the internal surface that the bolt 04 matching with nut 05 can pass the first through hole 011, the first protruding structure 033 of cover plate 01 can block nut 05, to limit nut 05 with respect to coupling 03 rotation.
When needs connect two cover plates 01 and support 02, first bolt is passed to the first through hole 011 of cover plate 01, again bolt 04 is passed to the third through-hole 032 coupling 03 and is stuck in the nut 05 in the first protruding structure 033 from a side of the second protruding structure 034 of coupling 03, but now not too many through nut 05, in order to avoid impact step below; By bolt 04 with coupling 03 and nut 05 through support 02, then rotate a certain angle, for example 90 degree, make coupling 03 cannot wear back the second through hole 021, and the second protruding structure 034 can snap in the second through hole 021, and limit the rotation of body 031; Then, toward retraction, the second protruding structure 034 is snapped in the second through hole 021 on bolt 04, now just can swivel bolt 04, thus realize the connection to cover plate 01 and support 02.

In this technological scheme, coupling 03 fitted bolt 04 and nut 05 can be realized the connection between sealing or semiclosed situation lower cover plate 01 and support 02, and do not need on-the-spot tapping, have reduced the requirement to cover plate 01 thickness, have reduced cost of production; And coupling 03 can be used as general part, be applied to, in various sealings or semi-enclosed connection, can facilitate the exchange of part under different situations.
Preferably, body 031, the first protruding structure 033 and the second protruding structure 034 are one-body molded.In this technological scheme, coupling 03 adopts integrated mode to obtain, and has reduced the quantity of part, has saved the process of assembling, convenient for production, has improved manufacturing efficiency.
Preferably, the first protruding structure 033 bends and forms in opposite directions; And/or second protruding structure 034 bend and form in opposite directions.In this technological scheme, the first protruding structure 033 and the second protruding structure 034 can directly obtain by modes such as punching presses, easily realize; The first protruding structure 033 and the second protruding structure 034 can all adopt the mode of punching press to obtain, so only need carry out punching press processing and punch obtaining coupling 03 to a plate, have farthest simplified production procedure, have improved manufacturing efficiency.
Preferably, the first protruding structure 033 is symmetrical about axis; And/or second protruding structure 034 symmetrical about axis.
In this technological scheme, because 034 of the first protruding structure 033 and the second protruding structure need to realize the rotation with respect to body 031 with respect to the rotation of support 02 and nut 05 of restriction body 031, so do not need complicated shape, the first protruding structure 033 and/or the second protruding structure 034 are symmetrical, simple in structure and practical about the axis of self.
Preferably, the axis of the first protruding structure 033 is vertical with the axis of the second protruding structure 034.Article two, axis is mutually vertical, makes the structure of coupling 03 more regular, and moulding is convenient.
Preferably, the first through hole 011 and the second through hole 021 are waist-shaped hole, and the axis that passes the first through hole 011 end arc structure is angle with the axis that passes the second through hole 021 end arc structure and arranges.
Preferably, described angle is right angle, and the axis that passes described the first through hole 011 end arc structure is mutually vertical with the axis that passes described the second through hole 021 end arc structure.
In this technological scheme, the first through hole 011 and the second through hole 021 are waist-shaped hole, thus only drill bit transverse shifting can need be obtained, easy to process, and meet the usage requirement of coupling 03; And employing waist-shaped hole, facilitate the position of adjusting bolt, reduced the required precision that cover plate and support is added to punch position in man-hour, reduced cost of production.
