SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an anti-disassembly screw to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a prevent tearing open screw, includes the external screw thread pole, the top of external screw thread pole is equipped with the screw head, the screw head is narrow round platform shape setting under the upper width, the upper end middle part of screw head is connected with the spliced pole, the upper end of screw head is equipped with the ring channel, the bottom of spliced pole is equipped with annular groove with the junction of screw head, the spiro union has a screw thread section of thick bamboo on the spliced pole, screw thread section of thick bamboo bottom spiro union is in the ring channel, the upper end of spliced pole is connected in hexagon nut's lower extreme middle part.
As the further optimization of the technical scheme, the height of the hexagonal screw cap is 3.85mm, the height of the connecting column is 5mm, and the diameter of the connecting column is 2 mm.
As the further optimization of this technical scheme, the upper end diameter of screw head is 7mm, the lower extreme diameter of screw head is unanimous with the diameter of external screw rod, the length of external screw rod is 4 mm.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, convenient to use through torsion, twists off the spliced pole of the higher authority via annular groove, and such screw of preventing tearing open can not be demolishd again, has a fine guard action to the lithium cell, and the lithium cell is sealed waterproof.
Drawings
FIG. 1 is a schematic perspective view of the present invention;
fig. 2 is a schematic view of the front view structure of the present invention.
In the figure: 1 hexagonal nut, 2 spliced poles, 3 screw heads, 4 external screw thread rods, 5 threaded cylinders, 6 annular grooves and 7 annular grooves.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides an anti-tear screw open, includes external screw thread pole 4, the top of external screw thread pole 4 is equipped with screw head 3, screw head 3 is the setting of narrow round platform shape under the width, the upper end middle part of screw head 3 is connected with spliced pole 2, the upper end of screw head 3 is equipped with ring channel 7, the bottom of spliced pole 2 is equipped with annular groove 6 with the junction of screw head 3, the spiro union has a screw thread section of thick bamboo 5 on the spliced pole 2, 5 bottom spiro unions of screw thread section of thick bamboo are in ring channel 7, the upper end of spliced pole 2 is connected in hexagon nut 1's lower extreme middle part.
Specifically, the height of hexagonal nut 1 is 3.85mm, the height of spliced pole 2 is 5mm, the diameter of spliced pole 2 is 2 mm.
Specifically, the upper end diameter of screw head 3 is 7mm, the lower extreme diameter of screw head 3 is unanimous with the diameter of external screw thread pole 4, the length of external screw thread pole 4 is 4 mm.
Specifically, when the anti-dismounting screw is used, the threaded cylinder 5 and the connecting column 2 are locked, so that the bottom of the threaded cylinder 5 is screwed in the annular groove 7, the connecting column 2 and the screw head 3 are further connected through the threaded cylinder 5, the integral structural strength of the connecting column 2 and the screw head 3 is increased, and therefore when a torque is applied to the hexagonal nut 1 by a wrench, the anti-dismounting screw can be smoothly connected with a shell of a lithium battery pack (box), and the connecting column 2 and the screw head 3 cannot be twisted off under the action of the torque;
the disassembly-preventing screw is connected with the shell of the lithium battery pack (box) through a wrench, the wrench is clamped on the hexagonal nut 1, and then the disassembly-preventing screw is rotated, so that the external threaded rod 4 is connected with the shell of the lithium battery pack (box), the shell of the lithium battery pack (box) is sealed, and the lithium battery can be completely protected by the shell of the lithium battery pack (box);
the threaded cylinder 5 is unscrewed, so that the lower end of the threaded cylinder 5 is separated from the annular groove 7, the annular groove 6 is arranged at the joint of the bottom of the connecting column 2 and the screw head 3, the connecting column 2 above is twisted off through the annular groove 6 by torsion, the anti-dismantling screw cannot be dismantled any more, a good protection effect is realized on the lithium battery, and the lithium battery is sealed and impermeable.
