Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
With reference to shown in Fig. 1 and Fig. 2, pull-type bolt device, comprise lower platen 1, below lower platen 1, both sides are provided with rotatable support tooth 7, fixed by little rivet 8 in the middle part of support tooth 7, and rotatable around little rivet, and support tooth 7 inside top is also conflicted with torsion spring 4 and is connected, make two to support tooth 7 tops and have an outside active force all the time, wherein torsion spring 4 is set on the large rivet 1 that is fixed on lower platen 1;
Lower platen 1 inside is also connected with pull-type handle 6 by stage clip 3, described stage clip 3 is S type spring, S type spring is flat shape, not high to the space requirement between lower platen 1 and pull-type handle 6, well can be arranged on inside, reduce small product size, and stage clip 3 one end be connected with pull-type handle 6, the other end is fixedly connected with the large rivet 2 12 be fixed on lower platen 1, can give the continuous action power that 6 one, pull-type handle is downward like this;
Be positioned at lower platen 1 side bottom pull-type handle 6 and be vertically installed with triangle turnup structure 9, conflict with the support tooth 7 of both sides below described lower platen 1 respectively and be connected in inclined-plane, triangle turnup structure 9 both sides, when pull-type handle 6 pulls, triangle turnup structure 9 rises thereupon, along with its inclined-plane glides bottom support tooth 7, obtain an outside active force, and pull-type handle 6 top is provided with the inclination handle 11 of inclination 30 °, be convenient to user and pull pull-type handle 6, its angle is not easily excessive, such as, when becoming vertical, hook formation will certainly be formed, easily be hooked to miscellaneous part, wherein be provided with anti-slip tank on inclination handle 11 surface, in order to avoid cause slippage when operating,
Lower platen 1 is also covered with top board 2, top board 2 top is connected with large rivet 2 12, middle part is connected with large rivet 1, bottom is connected with large rivet 3 14, by on lower platen 1 arrange parts well cover between, wherein on pull-type handle 6 in order to dodge large rivet 2 12 and large rivet 1, turn round and look at escape groove 2 13 and escape groove 1 are set, leave space surplus, also define the motion bound of pull-type handle 6.
The operation principle of the present embodiment is as follows:
Bolt device of the present invention can effectively coordinate existing socket to use, during original state, pull-type handle 6 passes through the downward active force of stage clip 3, bottom is close to lower platen 1 lower bottom part all the time, the outside tension force of torsion spring 4 is passed through at support tooth 7 top, two ends stretch out in lower platen 1 both sides, and support then be close to triangle turnup structure 9 bottom tooth 7 inclined-plane on.
During use, directly touched by bolt device of the present invention and insert socket, socket latch edge is touched at support tooth 7 top, obtains a power to the inside, and retraction after extruding torsion spring 4 is downward along socket latch wall, looses one's grip behind in-position.
Finish using when needing to extract, pull out inclination handle 11,6, pull-type handle moves upward, stage clip 3 becomes large to the active force that pull-type handle 6 is downward, simultaneously, due to the motion of pull-type handle 6, then rise on inclined-plane bottom support tooth 7 on its triangle turnup structure 9 liang of inclined-planes and position on inclined-plane declines, make to move laterally bottom support tooth 7, support tooth 7 is by the setting of little rivet 8, then moving to the inside in top, and gives torsion spring 4 one active forces and bounce back in lower platen 1, so just can be extracted by latch smoothly.
After extracting latch, unclamp inclination handle 11, the active force of stage clip 3 to pull-type handle 6 is discharged, pull-type handle 6 is moved downward, after moving downward, its triangle turnup structure 9 declines thereupon, is inwardly moved, be back to initial position bottom support tooth 7 by the tension force that torsion spring 4 is outside with inclined-plane.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc.,
All should be included within protection scope of the present invention.
