Description
Technical field
The invention belongs to the technical field of auto parts machinery, more particularly to a kind of locking mechanism.
Background technology
The present invention relates to a kind of locking mechanism of folding Der Kofferraumdeckel.Traditional pickup type lorry is used for carrying not
With the compartment of goods.Generally, compartment is covered by a Der Kofferraumdeckel, to protect delivered goods not by adverse weather institute shadow
Ring, while pick up lorry is also more attractive in appearance.And locking mechanism can then ensure that Der Kofferraumdeckel is steady in vehicle traveling process, together
When Der Kofferraumdeckel can be allowed more integrated with automobile.
At present, the locking mechanism of universal truck cover of pick-up truck mainly divides three kinds：One is cam structure, though this structure zero
Part negligible amounts, it is easy to install, but have under car Long-term Vibration the risk of loosening；Secondly being double acting lock construction, can realize fast
Speed tears lock open, but needs to increase side lever, and compartment is impacted using space；Thirdly be spring locking mechanism, easily lock it is readily removable, but
Higher is required to spring performance, and without self-locking structure, it is long-term use of because the decline of spring performance can influence locking effect.
In summary, there is the technology that easily locking effect is poor caused by loosening and structure is larger in current locking mechanism
Defect.
The content of the invention
In view of this, this patent aims to provide a kind of simple installation, Stability Analysis of Structures, moreover it is possible to has the small lock of auto-lock function
Locking structure, the skill that easily locking effect is poor caused by loosening and structure is larger be present for solving the locking mechanism of prior art
Art defect.
The invention provides a kind of locking mechanism, including：Handle, frames, support bar, locking bail and connecting rod, it is described
Frames include slave arm and fixed block；
The locking bail is connected with the first end of the connecting rod, is the first tie point；
Second end of the connecting rod is connected with the second installation site of the handle, is the second tie point；
First installation site of the handle is connected with the slave arm of the frames, is the 3rd tie point；
The locking bail is connected by the support bar with the fixed block of the frames, is the 4th tie point；
The fixed block of the frames is connected with the support bar；So that the locking mechanism is in locking state, institute
The first tie point, second tie point and the 3rd tie point are stated on same straight line, when released state, described
One tie point, second tie point and the 3rd tie point are not arranged on the same straight line.
Preferably, the locking bail is hinged by the first end of pin and the connecting rod.
Preferably, the second end of the connecting rod is hinged by the second dress site of pin and the handle.
Preferably, the first installation site of the handle is hinged by pin and the slave arm of the frames.
Preferably, the locking bail utilizes pin-hinges by the fixed block of the support bar and the frames.
Preferably, the fixed block of the frames is fixedly connected with the pin of the support bar.
Preferably, the support bar is specially big homalocephalus tubular rivet.
Preferably, the handle, the frames, the support bar, the locking bail and the connecting rod are nylon
It is prepared with glass fibre.
Preferably, the handle is provided with support bar insertion position.
Preferably, the locking bail includes locking limited mouth.
Easily locking effect difference and knot caused by loosening be present for the locking mechanism of prior art in the purpose of the present invention
The larger technological deficiency of structure.Therefore, a kind of locking mechanism disclosed by the invention, the present invention include：Handle, frames, support
Bar, locking bail and connecting rod, the frames include slave arm and fixed block；The first end of the locking bail and the connecting rod connects
Connect, be the first tie point；Second end of the connecting rod is connected with the second installation site of the handle, is the second tie point；Institute
The the first installation site for stating handle is connected with the slave arm of the frames, is the 3rd tie point；The locking bail passes through institute
The fixed block that support bar is stated with the frames is connected, and is the 4th tie point；The fixed block of the frames and the branch
Strut connects；So that the locking mechanism is in locking state, first tie point, second tie point and the described 3rd
Tie point is on same straight line, when released state, first tie point, second tie point and the 3rd connection
Point is not arranged on the same straight line.(it is respectively handle, frames, locking bail and company present invention employs lanar four rod mechanism
Bar is connected with each other and formed), by pulling handle to away from support bar direction, locking bail is under the drive of connecting rod, with the of connecting rod
The pin at two ends moves in a circle for the center of circle, when the locking bail and pin of the first end of connecting rod, the second end of connecting rod and handle
Second installation site pin, and handle first installation site and frames slave arm pin in same straight line
When upper, i.e. when on same straight line, now whole locking mechanism reaches for the first tie point, the second tie point and the 3rd tie point
Dead-centre position, complete self-locking.When toward when pulling handle close to support bar direction so that the first tie point, the second tie point and the
Three tie points are not arranged on the same straight line, you can complete unblock so as to which locking bail is not on locking position is locked at.The lock of the present invention
Locking structure is widely used, and with auto-lock function, locking effect is preferable, and small volume, is not take up locked position.
