A kind of graphene grounding rod vertical connecting structure, including bottom ground bar, are characterized by: the bottom ground bar One end be pyramidal structure, the other end is coaxially connected with additional ground stick, and the bottom ground bar is spliced with additional ground stick Position is equipped with the covered joint seat extended towards additional ground stick, which has socket inner cavity, be socketed the inner circumferential wall of inner cavity On be evenly distributed with flexible clamping piece, the clamping piece from it is described socket inner cavity inner wall towards socket inner cavity inside prolong It stretches, and is obliquely installed along the axis direction of the covered joint seat, the additional ground stick is pacified on the outer wall of corresponding covered joint seat position Clamping boss equipped with cyclic structure, additional ground stick are also being equipped with the covered joint seat far from the one end for being equipped with clamping boss；

The additional ground stick is equipped with the abutting extended towards bottom ground bar in one end end face for being equipped with clamping boss The bottom of item, the socket inner cavity is equipped with the matching hole adaptable with item is abutted.

Using the above structure, one end of bottom ground bar is pyramidal structure, squeezes into grounding rod to the ground when can facilitate construction, In the socket of the other end it is intracavitary be distributed with elasticity clamping piece, by one end of additional ground stick be inserted in socket in it is intracavitary, be clamped it is convex Platform, which slips over the clamping piece, can be realized being fixedly connected for bottom ground bar and additional ground stick, and such connection type unless It by the way of violence disassembly, otherwise can not be pulled out, there is the advantages of splicing is secured, long service life；It is additional to connect The other end of ground stick, which is equipped with covered joint seat, can guarantee that additional ground stick can be expanded infinitely, so that it is enough to guarantee that lightning-arrest earth mat has Construction length.Meanwhile the setting for abutting item can further guarantee the bonding strength of adjacent two grounding rods.

As preferred: the abutting item includes three protrusions peripherally and outwardly extended along it, and arbitrary neighborhood two convex The angle between portion is 120 ° out；The clamping groove that the matching hole is adapted by three with the protrusion forms.Using above-mentioned Structure can prevent from relatively rotating between adjacent two grounding rods.

As preferred: the diameter of the clamping boss is gradually reduced along the axial direction of additional ground stick.Using the above structure, just In assembly.

As preferred: the covered joint seat is made of metal material.Using the above structure, convenient for manufacture.

As preferred: the clamping boss is made of metal material.Using the above structure, convenient for manufacture.

As preferred: the quantity of the clamping piece is 5.

Compared with prior art, the utility model has the beneficial effects that

Using graphene grounding rod vertical connecting structure provided by the utility model, structure is simple, adjacent two grounding rods Splicing it is convenient, rapid and firm, be conducive to the rapid construction of lightning-arrest power grid.

Specific embodiment

The utility model is described in further detail with attached drawing with reference to embodiments.

As shown in Fig. 1,3 and 4, a kind of graphene grounding rod vertical connecting structure, ground structure is mainly by bottom ground bar 1 It is spliced with additional ground stick 2, wherein the need one of bottom ground bar 1, additional ground stick 2 can be more.

As shown in Fig. 2 to 5, for convenience of bottom ground bar 1 is squeezed into the ground, one end of bottom ground bar 1 is pyramidal structure 1a.Realize quick connection for square bottom ground bar 1 and additional ground stick 2, bottom ground bar 1 with 2 splice bits of additional ground stick The covered joint seat 1b extended towards additional ground stick 2 is installed, covered joint seat 1b has socket inner cavity 1c, is socketed the circumferential direction of inner cavity 1c Flexible clamping piece 1d is evenly distributed on inner wall, the clamping piece 1d is out of, the socket inner cavity 1c inner wall direction socket The internal stretch of chamber 1c, and be obliquely installed along the axis direction of the covered joint seat 1b, the additional ground stick 2 is in corresponding covered joint seat One end of additional ground stick 2 is inserted in socket by the clamping boss 2a that the outer wall of the position 1b is equipped with cyclic structure in assembly In chamber 1c, clamping boss 2a, which slips over the clamping piece 1d, can be realized being fixedly connected for bottom ground bar 1 and additional ground stick 2, And otherwise such connection type can not be pulled out unless by the way of violence disassembly, there is splicing securely to use The advantage of service life length.
