Specific embodiment
In order to facilitate the understanding of those skilled in the art, below in conjunction with attached drawing and embodiment to the utility model carry out into
One step detailed description.
Embodiment one
Refering to fig. 1 ~ 3, a kind of quick clamping device is typically used as lightweight component as the connection between two components
It connects, such as the components such as control panel in automobile.Quick clamping device includes expansion rod 1, connector sleeve 2 and expansion-head 3, described swollen
Swollen head 3 is located at 2 one end of connector sleeve, and the plastic parts that connector sleeve 2 and expansion-head 3 are integrally formed, and can generally use integral type
Injection molding, preferably the selection preferable glue material of plasticity, so that expansion-head 3 has the ability preferably to resile.Expansion rod 1 can
To use metalwork or plastic parts, there is certain rigidity.Have in the connector sleeve 2 and expansion-head 3 and is inserted for expansion rod 1
The cavity connect, the expansion rod 1 can be plugged in connector sleeve 2 and dilating expansion head 3.Connector sleeve 2 is a hollow tubular
Structure is provided with connection structure 21, connection structure 21 can be according to specific as fixing with a component on the connector sleeve 2
The component of connection needs to be arranged, such as automobile control panel, the circular ring shape fixture block of opening can be arranged on automobile control panel,
Setting a centre for connection structure 21 is the structure that there is side block at rod-shaped, both ends, so that connection structure 21 can snap onto bar
In shape structure, and the fixation of panel Yu connection structure 21 is realized come defined position by the side block at both ends.
Refering to fig. 1 ~ 3, the expansion-head 3 is the structure of more valve annular spreads, and two valves, nature is generally at least arranged
Under, each valvular structure is in purse up state when expansion rod 1 can be plugged in connector sleeve 2 and be reached on the inside of each valvular structure
When each valvular structure can be strutted, matched so that expansion-head 3 is first tucked into size on a connecting plate 4 and states expansion-head 3
Hole in, then valvular structure strutted by expansion rod 1, the overall structure of connector sleeve 2 and expansion-head 3 can be fixed on connecting plate
On 4, so as to which connection structure 21 to be also secured on connecting plate 4, the connection of two components is realized.Expansion rod 1 is using slotting
The mode connect is directly inserted into inside connector sleeve 2 and expansion-head 3, so as to realize Fast Installation.Expansion rod 1 can again from
It extracts, two components is separated, and reusable inside connector sleeve 2 and expansion-head 3, to realize recyclable plug.
Connection section between the expansion rod 1 and connector sleeve 2 can be the other shapes other than round or circle, such as
Rectangle, if can be rotated between expansion rod 1 and connector sleeve 2, using round if expanded using other shapes
It cannot rotate between bar 1 and connector sleeve 2, when use can select according to actual needs.
Refering to Fig. 3,1 rear end of expansion rod is provided with handle 12, facilitates grafting when installation.The front end of expansion rod 1 is cut
Face shape can be more slightly larger than rest part section, or by connector sleeve 2 close to 1 side of expansion rod entrance be arranged it is slightly smaller, always
Guarantee expansion rod 1 can be inserted in connector sleeve 2, but need certain strength that can just insert or pull out, be arranged in this way avoid it is swollen
What expanding rod 1 was connect with connector sleeve 2 too loose is easy to fall.
Anti-skid structure can be set in 3 periphery of expansion-head, such as non-slip texture is arranged in injection mold, thus expansion-head 3
It is connect with mounting plate 4 stronger.Handle 12 also can be set when anti-skid structure facilitates installation and be affectedly bashful.
Refering to fig. 1 ~ 3, by taking control panel is in the installation on automotive interior mounting plate 4 as an example, the quick-clamping of the present embodiment is filled
It sets in use, first control panel is fixed in the connection structure 21 being arranged on connector sleeve 2, then expansion-head 3 is filled in mounting plate 4
Mounting hole in, finally by expansion rod 1 be inserted into connector sleeve 2 until expansion-head 3 in, expansion-head 3 is strutted, can be by control panel
It is fixed on mounting plate 4.Expansion rod 1 is extracted when needing to dismantle.Installation and removal are all easily quick.
Embodiment two
Refering to Fig. 4 and Fig. 5, the overall structure of the present embodiment is the same as example 1, the difference is that, the expansion-head
3 inner walls are provided with card slot 31, and 1 front end of expansion rod is provided with and the matched fixture block 11 of card slot 31.Fixture block 11 can be set to
Such as the fixture block of the unidirectional clamping in Fig. 4, when hence for the mounting structure for needing for two components to be fixed, the card of expansion rod 1
When block 11 is inserted into 31 position of card slot, expansion rod 1 can be realized and firmly fix with connector sleeve 2 and expansion-head 3, non-dismountable.
One can also be set fixture block 11 to such as two-way fixture block elastic in Fig. 5,1 connector sleeve 2 of expansion rod may be implemented in this structure
And the connection of expansion-head 3 is stronger, expansion rod 1 is not easy to fall off from connector sleeve 2 and expansion-head 3, but expansion rod 1 can still pull out
Out.
Embodiment one is connect with expansion rod 1 in embodiment two with the mode that connector sleeve 2 and expansion-head 3 are grafting, according to
It needs, it can also be using being threadedly coupled between the expansion rod 1 and connector sleeve 2, the card slot 31 is annular slot, due to screw thread
The bonding strength of connection is higher, can connect two larger components using being threadedly coupled.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in
Within the protection scope of the utility model claims.
