Abstract
The invention discloses a stepped clamping structure for connecting plates of different thicknesses, which comprises a clamping block and a clamping hole column, wherein the clamping block is a right-angle triangle block, the inclined plane of the clamping block is provided with a plurality of continuous push teeth; a right-angle trapezoidal hole through which the clamping block passes is formed on the clamping hole column; and the clamping block penetrates through the right-angle trapezoidal hole in the clamping hole column in radial and is meshed with the meshing teeth of the clamping hole column. The clamping structure is particularly suitable for connecting two plates which are not overlapped together, the thickness of the plate determines the meshing between the different push teeth on the clamping block and the meshing teeth on the clamping hole column; when the plates are relatively thick, the meshing teeth at the front end of the clamping block are meshed with the meshing teeth on the clamping hole column; and when the plates are relatively thin, the meshing teeth at the rear ends of the clamping block are meshed with those on the clamping hole column. The structure is simple, convenient to install, capable of connecting the plates of different thicknesses, and in particular suitable for connecting the plates which are not required to be dismantled after installation.
Description
Technical field
The present invention relates to
OneSpecies stage formula interface arrangment can be used for the connection between the different-thickness sheet material.
Background technique
During automobile assembling, often the ornamental piece of various different-thickness need be installed on the vehicle body, in case and these ornamental piece installations just can not dismantled basically again.Screw connection structure is easy to generate stripped thread and causes looseningly, and sheet material need correspondingly increase spiro rod length when thicker; And modes such as other buckle connections can't satisfy the connection between the different-thickness sheet material again.
Summary of the invention
The invention provides a kind of cascade interface arrangment simple in structure, easy for installation, can be used for the connection between the sheet material of different-thickness, the connection between the sheet material that does not need to dismantle after being particularly suitable for installing.
In order to achieve the above object, a kind of cascade interface arrangment that is used to connect different-thickness sheet material of the present invention, comprise fixture block (1) and hole clipping post (2), key is: described fixture block (1) is the right angle trigonometry piece, and the inclined-plane (11) of this fixture block (1) is provided with a plurality of continuous teeth (12) that push away; Described hole clipping post (2) is made of cylindrical body (21) and the termination (22) that is positioned at cylindrical body (21) lower end, described termination (22) and the diameter of termination (22) coaxial with described cylindrical body (21) is greater than the diameter of cylindrical body (21), have the right-angled trapezium hole of passing for fixture block (1) (23) on the described hole clipping post (2), the tapered plane in described right-angled trapezium hole (23) is positioned at described cylindrical body (21), this tapered plane is provided with a plurality of continuous described engaging tooths (24) that push away tooth (12), the lower plane in described right-angled trapezium hole (23) is the upper-end surface of described termination (22), described fixture block (1) radially passes the right-angled trapezium hole (23) of described hole clipping post (2) and meshes together by its engaging tooth (24) that pushes away tooth (12) and hole clipping post (2), the bottom plane (13) of described fixture block (1) is parallel with the upper-end surface of described hole clipping post (2) termination (22), the termination (22) of described hole clipping post (2) is from the top down successively by the first end (22a) of coaxial line, neck (22b) and the second end (22c) constitute, and the diameter of described neck (22b) is gone up the diameter on plane less than the diameter and the second end (22c) of described first end (22a) lower plane.
Connection between the two boards that this interface arrangment is specially adapted to not be superimposed together.Before the installation, the hole of passing through for hole clipping post cylindrical body need be set on first sheet material, and on second sheet material, set up a projection, the draw-in groove that the neck for the hole clipping post snaps in is set on the projection.During installation, neck with the hole clipping post is connected on second sheet material by the draw-in groove on second sheet material earlier, again the cylindrical body of hole clipping post is passed the circular hole on first sheet material, fitted in the upper-end surface of the termination of the lower end surface of first sheet material and hole clipping post, then fixture block is pushed in the right-angled trapezium hole of hole clipping post, the engaging tooth that pushes away tooth and hole clipping post of fixture block is meshed together.The thickness of first sheet material has determined that the different teeth that push away are meshed with engaging tooth on the hole clipping post on the fixture block, when sheet material is thicker, be meshed with engaging tooth on the hole clipping post by the engaging tooth of fixture block front end, when sheet material is thin, be meshed with engaging tooth on the hole clipping post by the engaging tooth of fixture block rear end; Finally, first sheet material is pressed between the upper-end surface of fixture block bottom plane and hole clipping styletable head, and second sheet material is connected to the neck of hole clipping post.Push away the structure of tooth, fixture block can only be pushed away forward in the right-angled trapezium hole of hole clipping post, can not shrink back, in case assembling is finished then no longer dismantle.
Described fixture block (1) inclined-plane (11) is provided with lug (14), and described lug (14) is positioned at the end that pushes away tooth (12), and this lug (14) extends upward perpendicular to the bottom plane (13) of fixture block (1), and the gripping of fixture block is convenient in the setting of lug.
Described fixture block (1) and hole clipping post (2) are working of plastics.Need the special case dismantled once in a while for some, the interface arrangment of working of plastics is easier fast, like a cork with its destruction.
The invention has the beneficial effects as follows:
1) simple in structure, design is ingenious, need not assistant tool and just can realize quick mounting, and convenient, laborsaving;
2) applied widely, can be used for the connection between the different-thickness sheet material;
3) secure and reliable connection is disposable product.
