Description
Technical field
The utility model is related to parts to be fixedly mounted field more particularly to a kind of connection that parts are installed on metal plate
Structure.
Background technology
It is threadedly coupled as a kind of common connection mode, is widely used when parts are fixedly mounted.But for vehicle body
For metal plate, because metal plate is relatively thin, thread mill drilling, the through hole reserved on metal plate it can not cannot be used for being threadedly coupled on metal plate,
The mode for causing to be threadedly coupled does not apply on metal plate, and other modes connection can be used, can increase the complexity of structure, cause to give birth to
Produce the increase of cost and the reduction of production efficiency.
Utility model content
The utility model overcome it is of the prior art because metal plate is relatively thin, can not on metal plate thread mill drilling, cause spiral shell
Line connection mode on metal plate do not apply to the shortcomings that, provide it is a kind of on metal plate install parts connection structure.
The utility model realize goal of the invention the technical solution adopted is that：A kind of connection knot that parts are installed on metal plate
Parts are mounted on the metal plate with through hole by structure by attachment device, and the attachment device includes expansion pin, expansion sleeve
And nut, expansion pin one end have taper, the expansion pin other end is equipped with screw thread, and the tube wall of expansion sleeve is laid in the axial direction
There is one group of notch, the outside dimensions of expansion sleeve is corresponding with the internal diameter size of the through hole of metal plate, and expansion pin has the one of taper
In expansion sleeve, expansion sleeve is sleeved in the through hole of metal plate end cap, and parts are equipped with the connection with expansion pin grafting
Hole, parts are fixedly mounted on by nut in expansion pin.
Further, the pin wall of the expansion pin is equipped with a /V plane in the axial direction, the connecting hole of parts
Hole size is corresponding with the outside dimensions of expansion pin.
The beneficial effects of the utility model are：When the expansion pin of the utility model is tightened with nut, the expansion pin with taper
Expansion sleeve is strutted, expansion sleeve is made to be fastenedly connected with metal plate, attachment device is fixed on metal plate, and parts are fixed on connection
On device, realization parts are fixedly connected with metal plate.The utility model have it is simple in structure, easy for installation, using extensively etc.
Advantage.
The utility model will be further described with specific embodiment below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structural exploded view of the utility model.
Fig. 2 is the parts of the utility model and the scheme of installation of expansion pin.
Fig. 3 is the sectional view of the utility model.
In attached drawing, 1 be nut, 2 be parts, 2-1 be connecting hole, 3 be expansion pin, 3-1 be limited bit plane, 4 be expansion
Casing, notch 4-1,5 be metal plate, 5-1 is through hole.
Specific embodiment
As shown in drawings, a kind of connection structure that parts are installed on metal plate of the present embodiment, will by attachment device
Parts 2 are mounted on the metal plate 5 with through hole 5-1.The attachment device includes expansion pin 3, expansion sleeve 4 and nut 1.It is swollen
3 one end of expansion pin has taper, and 3 other end of expansion pin is equipped with screw thread.The tube wall of expansion sleeve 4 is laid with one group in the axial direction
Notch 4-1.The outside dimensions of expansion sleeve 4 is corresponding with the internal diameter size of the through hole 5-1 of metal plate 5.Expansion pin 3 has taper
One end is sleeved in expansion sleeve 4, and expansion sleeve 4 is sleeved in the through hole 5-1 of metal plate 5.Expansion pin 3 with taper is by expansion sleeve
When pipe 4 is strutted along notch 4-1, tube wall and the metal plate 5 of expansion sleeve 4 fit closely.Parts 2 are equipped with to be inserted with expansion pin 3
The connecting hole 2-1 connect, to prevent that expansion pin 3 rotates in installation process, the pin wall edge of the preferred expansion pin 3 of the present embodiment
Axis direction is equipped with a /V plane 3-1, and the hole size of the connecting hole 2-1 of parts 2 is opposite with the outside dimensions of expansion pin 3
Should, parts 2 are also equipped with /V plane accordingly.By expansion pin 3 and parts 2 in the dimensional fits of interface, limitation is swollen
Expansion pin 3 rotates.Parts 2 are fixedly mounted on by nut 1 in expansion pin 3.
During in-site installation, the expansion sleeve 4 for being set with expansion pin 3 is inserted into the through hole 5-1 of metal plate 5 first, then will
Parts 2 are mounted in expansion pin 3, finally the installation nut 1 outside parts 2, and in 1 rundown process of nut, axis occurs for expansion pin 3
To displacement, expansion pin 3, which has in one end immigration expansion sleeve 4 of taper, struts expansion sleeve 4, makes expansion sleeve 4 and metal plate 5
It fits closely.By the structure of the utility model, beneficial to the through hole 5-1 carried on metal plate 5, using thread connecting mode by zero
Part 2 be mounted on metal plate 5 on, have many advantages, such as it is simple in structure, easy for installation, using extensive.
