Description
Technical field
The present invention relates to a kind of fuse opening structure of box cover more particularly to a kind of fuse box cover easy opening structure and
Its application method reduces application limitation it is particularly applicable to reduce unlatching difficulty.
Background technique
On existing market, the open hole in vehicle fuse box lid is deep, needs using special opener, such as
Key or screwdriver deeply could wherein be opened, increase operation difficulty, limitation is larger, in addition, existing open hole shape
Shape is mostly rectangular, and hole is deep in addition, not only easily reduces the mechanical strength of fuse box cover itself, but also exterior quality is poor,
Unsightly.
Authorization Notice No. is CN205723416U, and authorized announcement date is that the utility model patent on November 23rd, 2016 discloses
A kind of external fuse box of the power battery for plug-in hybrid vehicle, the fuse box is in the power
It arranges outside battery, the fuse box includes pedestal and the upper cover that can releasably install on the base, at the bottom
It is closed with an inner space between seat and the upper cover, at least two binding posts, institute are fixedly disposed in the inner space
The one end for stating at least two binding posts is connect with the inside cable of the power battery respectively, and the other end is equipped with screw thread, and one protects
Dangerous silk will be releasably connected on the binding post via nut and screwing togather for screw thread, and the fuse is connected on described move
In the inside cable of power battery.Although the design can increase the fastness after fuse box connection, it is still required specially
Tool could open fuse box cover, and unlatching difficulty is higher, and the limitation of application is larger.
The information for disclosing the background technology part is merely intended to increase the understanding to the general background of present patent application, without
It should be considered as recognizing or implying in any form that the information constitutes existing skill already known to those of ordinary skill in the art
Art.
Summary of the invention
The purpose of the present invention is overcome the biggish defect of limitation that unlatching difficulty existing in the prior art is higher, applies
With problem, a kind of unlatching difficulty is lower, applies the lesser fuse box cover easy opening structure of limitation and its use are provided
Method.
In order to achieve the above object, the technical solution of the invention is as follows: a kind of fuse box cover easy opening structure, including
Locked groove and lock pin on its interior, the lock pin include pin shaft and plunger, the bottom surface of the plunger and outer end of pin shaft is vertical connects,
The inner end of pin shaft is located at the inside of locked groove, and the outer wall of pin shaft is threadedly coupled with the inside of locked groove；
The diameter of the plunger is greater than the diameter of pin shaft, offers open hole, the width of the open hole in the middle part of the plunger
Greater than the thickness of coin；The cross section of the open hole is arc structure, and radian is quadrant to 3/4ths circles.
The radian of the cross section of the open hole is semicircle.
The depth of the open hole is 5 millimeters, and width is 2 millimeters, and the radius of the circle where the cross section of open hole is 10
Millimeter.
The locked groove includes the outer end anchor ring from top to bottom set gradually, upper groove drum, intermediate anchor ring, lower groove drum, described outer
The vertical connection concordant with the top of upper groove drum of the inner end in end ring face, the bottom of upper groove drum is concordant with the intermediate outer end of anchor ring to hang down
It is direct-connected to connect, the vertical connection concordant with the top of lower groove drum of the inner end of intermediate anchor ring, radius, the pin of the inner ring of the outer end anchor ring
The radius of head, the radius of inner ring, the radius of pin shaft of centre anchor ring are sequentially reduced.
Folder is at there is interior external series gap between the outer wall of the plunger and the inner wall of upper groove drum.
The plunger is arranged lower than outer end anchor ring.
Be in contact at the top of the bottom of the lower groove drum and hollow bracket, the hollow cavity opened up in the middle part of hollow bracket it is transversal
The diameter in face is less than the diameter of the cross section of lower groove drum, and hollow cavity and the bottom extending shaft for being inserted into its inside carry out insertion cooperation, bottom
The top of extending shaft and the bottom end of pin shaft are coaxially connected, and the radius of bottom extending shaft is less than the radius of pin shaft.
The pin shaft, bottom extending shaft middle part offer a lower opening slot altogether, the top of the lower opening slot is located at pin shaft
Inside, the bottom end notch of lower opening slot intersects with the bottom surface of bottom extending shaft.
A kind of application method of above-mentioned fuse box cover easy opening structure, the application method is the following steps are included: elder generation
The lower edge of coin is inserted into open hole, after being inserted into bottom, is rotated further by coin, the coin of rotation drives through open hole to be locked
Pin rotation, until lock pin is back-outed.
The coin is the coin of five jiaos or unitary.
Compared with prior art, the invention has the benefit that
1, in a kind of fuse box cover easy opening structure and its application method of the invention, the diameter of plunger is greater than the straight of pin shaft
Diameter enables plunger to be stuck in locked groove, and exposed shape is circle, and there is no the unsmooth places of protrusion, and compare
It is round more beautiful compared with the square structure of the prior art, in addition, the width for the open hole being arranged in the middle part of plunger is greater than the thickness of coin
Degree, so that only needing a common coin, five jiaos or unitary can be inserted into open hole and be opened, not needed for the design
Specific purpose tool, easy to operate, the limitation that do not apply.Therefore, the present invention not only opens the limitation that difficulty is lower, applies
Property it is smaller, and sense of touch is smooth, good appearance.
2, in a kind of fuse box cover easy opening structure and its application method of the invention, the cross section of open hole is circular arc
Structure, the design can make the edge of open hole and coin more coincide, and unlatching is especially worked as in the rotation conducive to coin to open hole
The radian of the cross section in hole is half bowlder, better effect, in addition, reducing open hole on the basis of realizing that coin is opened
Depth avoids the deeper hole design used in the prior art for cooperation screwdriver, it is mechanical to reduce insurance of damage silk box cover
The risk of intensity.Therefore, it is lower not only to open difficulty by the present invention, but also mechanical strength is higher.
3, in a kind of fuse box cover easy opening structure of the present invention and its application method, locked groove includes from top to bottom successively
The outer end anchor ring of setting, upper groove drum, intermediate anchor ring and lower groove drum, lock pin include pin shaft and plunger, not only outer end anchor ring, upper slot
Cylinder, intermediate anchor ring, lower groove drum radius between there are unique design, and the half of outer end anchor ring, plunger, intermediate anchor ring, pin shaft
There is also corresponding Collaborative Design between diameter, purpose is provided to the realization that cooperation coin is opened, and both can ensure that the bottom of coin
Edge can be inserted into open hole, and be can ensure that and be inserted into certain depth, be limited without the locked groove outside by lock pin, to be conducive to
The realization of coin rotation open hole.Therefore, the present invention can not only realize that coin rotates open hole, and operation is convenient.
