Abstract

The utility model discloses a disassembly-resistant structure of a bolt. The bolt comprises a bolt rod and a bolt head, which connected with each other to a whole body, wherein the outer end face of the bolt head is concavely provided with a counter bore, the counter bore is internally and fixedly filled with a disassembly-resistant piece, the outer end face of the disassembly-resistant piece is concavely provided with a special disassembly hole, and a special disassembly tool is arranged aiming at the special disassembly/assembly hole. The condition that the bolt is disassembled by the means that a lawless person uses a bolt disassembling/assembling tool or other equivalent materials to extend into the counter bore can be effectively avoided, so that the connecting safety or the locking safety of a countersunk bolt can be greatly improved; the bolt can be conveniently disassembled and assembled by a user when necessary; and the special disassembling/assembling tool is connected with a hanging ring, so that the special disassembling/assembling tool can be conveniently carried with the user, for example, the special disassembling/assembling tool can be suspended on a keychain, and the like, so that the special disassembling/assembling tool can be preferably safeguarded.

Description

The tamper structure of bolt

Technical field

The utility model relates to the bolt field technology, refers in particular to a kind of tamper structure of bolt.

Background technique

Countersunk screw is widely used in that object connects and locking etc., and usually, the countersunk screw of application such as automobile, motorcycle adopts universal standard part more, so that manufacture, assemble and the back knot continues required dismounting operation such as maintain and replace etc.

As shown in Figure 4; It is the installment state schematic representation that lock for motorcycle is used bolt in the existing technology, it adopts be commonly used within hexagonal countersunk screw 100, can find in actual use; The lawless person is difficult opening under the situation of lock for motorcycle; Often select through dismounting aforementioned in hexagonal countersunk screw 100, with whole lock for motorcycle shell 201 and lock 202 and disassemble, to realize that motorcycle is stolen in the release of motorcycle from motorcycle.

By this, need work out a kind of new technological scheme and solve the problems referred to above, to satisfy the microminiaturized growth requirement of electronic product.

The model utility content

In view of this; The utility model is to the disappearance of existing technology existence; Its a kind of purpose provides a kind of tamper structure of bolt, and it can effectively prevent countersunk screw by the phenomenon of lawless person's dismounting, and person easy to use again can realize the dismounting to bolt when needed.

For realizing above-mentioned purpose, the utility model adopts following technological scheme:

A kind of tamper structure of bolt; Bolt includes bolt shank and the bolt head that one connects; The exterior edge face of this bolt head is concaved with counterbore; The fastening-type filling has anti-disassembling in this counterbore, and this anti-exterior edge face of disassembling is concaved with special-purpose dismounting hole, and special-purpose dismounting hole, the sidewall upper edge in this special use dismounting hole bearing of trend is opened and is concaved with the plurality of tooth-shaped groove; Correspondingly; Dispose special-purpose dismantling device; This special use dismantling device includes clamping part connected to one another and dismounting auxiliary section, and the form fit in the outer shape of this dismounting auxiliary section and aforementioned special-purpose dismounting hole convexes with the tooth bar that some and aforementioned serrate slot cooperates on its outer surface.

As a kind of preferred version, further be connected with on the said clamping part and be convenient to the suspension ring hanging, carry.

As a kind of preferred version, the outside of said clamping part is the regular hexagon structure.

As a kind of preferred version, said counterbore is the regular hexagon counterbore, and correspondingly, aforementioned anti-outside of disassembling also is the regular hexagon structure.

As a kind of preferred version, said anti-exterior edge face of disassembling keeps flushing with the exterior edge face of aforementioned bolt head.

The utility model compared with prior art has tangible advantage and beneficial effect; Particularly; Can be known that by technique scheme mainly lying in the interior fastening-type filling of this counterbore has anti-disassembling, this prevents that disassembling the exterior edge face is concaved with special-purpose dismounting hole; Special-purpose dismantling device is equipped with and to this special use dismounting hole; On the one hand, instrument or other of effectively avoiding the lawless person to use assembling-disassembling bolt commonly used is equal to object and stretches in the counterbore and Bolt dismantling is got off, and improved the connection or the locking Security of this countersunk screw greatly; On the other hand, person easy to use can realize the dismounting to bolt when needed; Next is, is connected with suspension ring on the aforementioned special-purpose dismantling device, is convenient to people and carries this special use dismantling device, and for example, it is first-class to be hung on key ring, and so, helping better certainly should the special use dismantling device.

Be structure characteristic and the effect of more clearly setting forth the utility model, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.
