Description

A kind of bolt

Technical field

This utility model belongs to machine components field, is specifically related to a kind of bolt.

Background technology

Bolt is one of the most used securing member of people, for the threaded securing member of cylinder of adapted nut, is made up of head and screw rod two parts, needs and nut screw connection, for being fastenedly connected two parts with through hole.

But people find in actual use, existing bolt also has a lot of area for improvement, such as, owing to the volume of bolt is smaller, and is inconvenient to mount and dismount；Or have to fix by corresponding instrument and dismantle in installation process, owing to corresponding tool type is single, limitation is relatively big, the most at hand without corresponding instrument, then is difficult to continue to progress from；Even if there being suitable instrument to install, also can there is nut and being blocked and inoperable problem by bigger stationary plane, so people need more suitably bolt to solve the problems referred to above.

Prior art there is also the bolt of some slotted heads, laborsaving installation need to be carried out by corresponding instrument, the termination slotting bolt of such as Patent No. CN201220599564.8, including the screw rod linked together and bolt head, is distributed screw thread in one section of screw rod or whole length；Groove is had on bolt head；Groove is with the axle of screw rod as axis of symmetry, its size and shape is constant to bottom land from notch, eliminate conventional bolt head and people is tripped the potential safety hazard causing traumatic injury, industrial injury etc., be simultaneous for termination slotting bolt and be equipped with associated spanner, the fixed block that including handle and is connected with handle, movable block.The front end of handle is respectively equipped with rotating shaft, chute, and its end is provided with uropore；The bottom of movable block is provided with tooth bar, and this tooth bar is located in chute；Rotating shaft is provided with band tooth regulation wheel, and this band tooth regulation wheel is provided with tooth；Tooth bar is meshed with tooth；A cylinder it is respectively provided with on fixed block and movable block, this cylinder one_to_one corresponding is perpendicular to fixed block, movable block, associated spanner is by adjusting the distance between two cylinders to adapt to the length of the groove on bolt head, two cylinders are inserted in the groove of bolt head, can flush with fixation surface and not appear or to unscrew bolt under even by precession bolt to its bolt head end face.Above-mentioned termination slotting bolt is in addition to needs associated spanner completes to install, if running into large-area fixed panel, and its groove being rotated in by associated spanner, the nut under being also secured to again, remove and install unusual inconvenience.

Utility model content

In order to solve the problems referred to above that prior art exists, this utility model provides a kind of easy for installation and labour-saving bolt.

The technical scheme that this utility model is used is:

A kind of bolt, including head 1 and screw rod integrated with described head 2, described screw rod 2 is for being provided with externally threaded cylinder, and described screw rod 2 is provided with restriction nut and the homodromal position-limit mechanism of bolt.

Described position-limit mechanism is the through hole 4 radially and running through setting along described screw rod 2 near the tail end direction of described screw rod 2.

Described position-limit mechanism is the first groove 3 offered along bolt-center direction of principal axis at described screw rod 2 tail end.

Described position-limit mechanism is radially and to run through the through hole 4 offered, and the first groove 3 offered at described screw rod 2 tail end along bolt-center direction of principal axis near the tail end direction of described screw rod 2 along described screw rod 2.

The grooved of described first groove 3 is yi word pattern, Triangle ID type, interior angle square, cross, rice font or interior hexangle type.

When the grooved of described first groove 3 is yi word pattern, its length is less than or equal to the diameter of described screw rod 2.

Described head 1 is turret head, round end, square spigot or countersunk head.

Described external screw thread is the one in full thread and non-full thread.

It is further opened with the second groove 5 along its central axis direction on head 1 top of described bolt.

The grooved of described second groove 5 is identical with the grooved of described first groove 3.

The beneficial effects of the utility model are: this utility model when being fastenedly connected the bigger plane with through hole with nut, put forth effort without the laborious both sides up and down in bigger plane are fixing, only by being arranged on the first groove of screw rod tail or the through hole of setting need to be run through along screw rod radial direction, i.e. can use extracting tool to insert in the first groove or in hole, utilize lever principle in the laborsaving installation and removal in the same side of bigger plane；In this utility model, the setting of through hole is without kit, and the suitable shaft in any aperture all can mount and dismount；Bolt simple modifications present in prior art can be used by this utility model, cost-effective, easy to use, it is simple to promote and use.

Detailed description of the invention

As shown in figures 1 to 6, this utility model provides a kind of bolt, and including head 1 and screw rod integrated with described head 2, described screw rod 2 is for being provided with externally threaded cylinder, and described screw rod 2 is provided with restriction nut and the homodromal position-limit mechanism of bolt.

This utility model is provided with restriction nut and the homodromal mechanism of bolt on screw rod, when bolts and nuts are fastenedly connected the bigger plane with through hole, put forth effort without the laborious upper and lower surface in bigger plane is fixing, only by being arranged on the first groove 3 of screw rod 2 afterbody or the through hole 4 of setting need to be run through along screw rod 2 radial direction, extracting tool is i.e. can use to insert in the first groove 3 or in through hole 4, in the laborsaving installation or removal in the same side of bigger plane；Bolt simple modifications present in prior art can be used by this utility model, cost-effective, easy to use, it is simple to promote and use.

In order to make dismounting and install the variation of bolt tool, lever principle is utilized to carry out laborsaving installation and removal, described position-limit mechanism, the through hole 4 offered is run through for the tail end along described screw rod 2 radial direction and near described screw rod 2, or the first groove 3 offered along bolt-center direction of principal axis at described screw rod 2 tail end, or through hole 4 and the first groove 3 are set simultaneously, the landing of nut can be prevented again while the setting of through hole convenient dismounting again or installation.

The grooved of described first groove 3 can include a variety of, such as yi word pattern, Triangle ID type, interior angle square, cross, rice font or interior hexangle type etc..

The bolt of any shape all can use along described screw rod 2 radial direction, and run through, near the tail end of described screw rod 2, the through hole 4 offered, or the first groove 3 offered at described screw rod 2 tail end, or the mode arranging through hole 4 and the first groove 3 can be turret head, round end, square spigot or countersunk head to reach the head 1 of effect of the present utility model, such as bolt simultaneously；External screw thread on screw rod can be full thread or non-full thread.

In order to make enhanced convenience during actual installation and dismounting, also can offer the second groove 5 on head 1 top of described bolt along its axial direction simultaneously, now optional that the grooved of described second groove 5 is consistent with the holding of the grooved of described first groove 3, when the afterbody of screw rod 2 is provided with the first groove, the when that the head 1 of bolt also being provided with the second groove 5 simultaneously, just can use same instrument select the first groove 3 of the second groove 5 of bolt head 1 or screw rod 2 afterbody to limit nut and bolt rotating Vortex, to complete dismounting and the installation of bolt.
