Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As shown in Figure 1, this utility model preferred embodiment provides the locking device of a kind of expansion link, for locking first sleeve 100 and the second sleeve pipe 200, this locking device includes the first lock mouth 1 and the second lock mouth 2, as shown in Figures 2 and 3, first lock mouth 1 has the connecting portion 11 being connected with first sleeve 100 and the clamping part 12 being connected with the second sleeve pipe 200, and the end opens of clamping part 12 has at least one breach 13 so that clamping part 12 resilient clamp is outside the second sleeve pipe.As shown in Figure 2 and Figure 4, the second lock mouth 2 is set in outer and with clamping part 12 the outer surface of clamping part 12 and abuts against, and the inner surface of the second lock mouth 2 is provided with step 21, and the outer surface of holding section 12 is provided with the projection 14 for offseting with step 21.
In the present embodiment, first sleeve 100 and the second sleeve pipe 200 are coaxially disposed, the internal diameter of first sleeve 100 is more than the external diameter of the second sleeve pipe 200, so that the second sleeve pipe 200 can extend in first sleeve 100, user can regulate the second sleeve pipe 200 according to demand and extend to the length in first sleeve 100, first sleeve 100 and the second sleeve pipe 200 is locked again through locking device.
As it is shown on figure 3, the column structure that the first lock mouth 1 is generally hollow, the first lock mouth 1 includes connecting portion 11 and clamping part 12, and first sleeve 100 is fixing with connecting portion 11 to be connected, and the second sleeve pipe 200 is plugged in clamping part 12.The end opens of clamping part 12 has at least one breach 13, makes clamping part 12 can reach expansion easily and tighten, so that clamping part 12 coordinates resilient clamp outside the second sleeve pipe 200 by tensioner, is conveniently plugged to clamping part 12 by the second sleeve pipe 200.In the present embodiment, breach 13 includes four, the end being evenly distributed on clamping part 12 that four breach 13 are spaced, first sleeve 100 be plugged in connecting portion 11 and with connecting portion 11 interference fit.
As shown in Figure 4, the column structure that the second lock mouth 2 is generally hollow, it is provided with shoulder hole in the second lock mouth 2, makes the inner surface of the second lock mouth 2 be formed with step 21.Concrete, shoulder hole includes the first connecting hole 22 and the second connecting hole 23 being connected, and the internal diameter of the first connecting hole 22 is less than the internal diameter of the second connecting hole 23.When second lock mouth 2 be set in the first lock mouth 1 outer time, the outer surface of the first connecting hole 22 and clamping part 12 abuts against, and inwardly pushes against clamping part 12, thus the bonding strength increased between clamping part 12 and the second sleeve pipe 200.
Preferably, the outer surface of clamping part 12 is provided with protruding 14, and projection 14 is positioned at the second connecting hole 23.When the second lock mouth 2 occurs to loosen with clamping part 12, protruding 14 support on step 21, come off from the first lock mouth 1 thus being prevented effectively from the second lock mouth 2.In the present embodiment, the outer surface of protruding 14 is the first inclined-plane, and the end of the second connecting hole 23 is provided with second inclined-plane suitable with this first inclined-plane.
Preferably, in order to increase the bonding strength between clamping part 12 and the second lock mouth 2, the outer surface of clamping part 12 is provided with boss 15, the first connecting hole 22 interference fit of boss 15 and the second lock mouth 2.
Preferably, the outer surface of the first lock mouth 1 is provided with block piece 16, it is to avoid the second lock mouth 2 comes off from the side of the first connecting portion 11 locking mouth 1.In the present embodiment, the external diameter of connecting portion 11 more than the external diameter of clamping part 12, the chuck that block piece 16 is connecting portion 11 to be formed with the junction of clamping part 12.
In sum, implement the locking device of a kind of expansion link of the application, have the advantages that
First, the end of the clamping part 12 of the first lock mouth 1 is provided with at least one breach, make clamping part 12 can reach expansion easily and tighten, so that clamping part 12 coordinates resilient clamp outside the second sleeve pipe 200 by tensioner, conveniently sleeve pipe is plugged to clamping part 12.
Secondly, be provided with step 21 in second lock mouth 2, clamping part 12 be provided with the projection 14 for offseting with this step 21, when second lock mouth 2 occur to loosen with clamping part 12 time, protruding 14 support on step 21, come off from the first lock mouth 1 thus being prevented effectively from the second lock mouth 2.
3rd, owing to the outer surface of the second inner surface locking mouth 2 and the first lock mouth 1 abuts against, and inwardly mouth 1 is locked in pushing and pressing first, make the first lock mouth 1 and sleeve pipe compact siro spinning technology, therefore the second lock mouth 2 only need to be set in outside the first lock mouth 1 by the application, conveniently regulative mode can be reached, and after assembling, each parts do not come off.
Finally, the simple in construction of the connecting device of the application, easy to use, it is beneficial to automated production.
Although this utility model is illustrated by specific embodiment, it will be appreciated by those skilled in the art that, when without departing from this utility model scope, it is also possible to this utility model is carried out various conversion and equivalent replacement.It addition, for particular condition or material, it is possible to this utility model is made various amendment, without deviating from scope of the present utility model.Therefore, this utility model is not limited to disclosed specific embodiment, and should include the whole embodiments falling in this utility model right.
