Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with specific embodiment technical scheme of the present invention being done and introducing in detail further.
As shown in Figure 3 and Figure 4, catch gear before the container that the embodiment of the present invention provides, comprise clamp handle 1, described clamp handle 1 is hinged with the clamp handle base 7 be fixed on before container on frame assembly A by handle bearing pin 6, and hinged with locking shackle 2 by shackle bearing pin 3, particularly, described handle bearing pin 6 can press with described clamp handle base 7 and be connected, described clamp handle 1 as shown in Figure 8, then is movably articulated on described handle bearing pin by the structure of described base clamp handle base 7; Described locking shackle 2 also can press with described shackle bearing pin 3 and be connected, then by hinged with described locking shackle 2 for described clamp handle 1; Described locking shackle 2 and container header board latch hook 9 clasp joint being connected frame assembly A and cargo box sideboard assembly B before described container; Described clamp handle 1 inside is provided with mounting bracket 8 on spring, and described spring is connected with spring 5 between mounting bracket 8 and described bail bearing pin 3.
As shown in Figure 5 and Figure 6, when needs are locked, the thorny handle bearing pin 6 of described clamp handle 1 and shackle bearing pin 3 rotate up motion, realize by free state I, change between most compressed state II to locking state III, when reaching locking state III, locking shackle is connected center O1 with container header board latch hook, handle bearing pin center O2, shackle bearing pin center O3 is in eccentric position, i.e. 3 distributions triangular in shape, spring is compressed, clamp handle 1 relies on self gravitation, the elastic force of spring 5 and the application force of locking shackle 2 reach stress balance, keep locking state preferably, when can prevent container from vibrating, locking was lost efficacy, in addition, compared with prior art, this catch gear avoids and adopts friction force to lock, and is conducive to improving its service life.
In this enforcement power specific implementation process, the two ends of described spring 5 can be separately fixed on described spring upper bracket 8 and described shackle bearing pin 3, but rotate up in the process of motion at described clamp handle 1, because described spring 5 is fixed on the change of described shackle bearing pin 3 one end position, the change in elastic force direction can be caused, cause the stressed deflection of bearing pin, for avoiding this problem, mounting bracket 4 under spring is also comprised in catch gear before described container, under described spring, mounting bracket 4 is arc plate structure, be overlapped on described shackle bearing pin 3, described spring 5 is connected to mounting bracket on described spring 8 with on the vertical center line of mounting bracket 4 under described spring, when handling, described spring lower bracket 4 can along the center rotating of described shackle bearing pin 3, realize spring force all the time on spring on mounting bracket and shackle bearing pin center line connecting direction, prevent the stressed deflection of bearing pin.
Under described spring, mounting bracket 4 can be provided with and strengthen protruding 41, as shown in Figure 9, to ensure the intensity of support.
In addition, as shown in Figure 7, for the structural representation of the clamp handle that the embodiment of the present invention provides, described clamp handle 1 comprises handle body 11 and is vertically connected at the side plate 12 of described handle body 11 both sides respectively, the inside of side plate 12 described in two groups is located at by described spring 5, and be parallel to described side plate 12 and connect, this structure, spring and peripheral parts can be avoided to interfere, affect locking operation, and described spring 5 is parallel to described side plate 2 arrange, the parts such as bearing pin, side plate can be avoided to be subject to deflecting force, reduce structural damage.
Described side plate 12 can offer lightening hole 13, make the motion of clamp handle 1 more flexible.
In operation, after described locking shackle 2 moves, its top can abut with frame assembly A before described container, thus produces friction, for avoiding wearing and tearing, can be provided with brace panel 10 before described locking shackle 2 and described container between frame assembly A.
Structure of the present invention, feature and action effect is described in detail above according to graphic shown embodiment; the foregoing is only preferred embodiment of the present invention; but the present invention does not limit practical range with shown in drawing; every change done according to conception of the present invention; or be revised as the Equivalent embodiments of equivalent variations; do not exceed yet specification sheets with diagram contain spiritual time, all should in protection scope of the present invention.
