Abstract
The utility model discloses a screw convenient to installation is easily to the problem of inaccurate screw hole when aiming at solving current mounting screw. A screw convenient to installation, includes screw body, screw body mainly comprises looks be connected together's screwhead and screw rod, this screw still includes the guide arm, be equipped with the guide arm through -hole along its axial in the screw body, guide arm slidable ground sets up in the guide arm through -hole, and the length of guide arm is greater than the length of guide arm through -hole. When installing this screw, through in wearing out the guide arm lower extreme partially insert screw hole of screw body lower extreme, very convenient this screw and the screw hole of just making is aimed at to thread damage when preventing that the screw from tightening is transferred perpendicularly with screw body to the accessible guide arm, and then has avoided smooth silk scheduling problem.
Description
Technical field
This utility model relates to a kind of screw, a kind of screw being easily installed.
Background technology
The weakest by the intensity of the screw thread in the sheet member that screw fastens, screw is careless slightly when entering is easy for damaged screw,
Sheet member is caused to be destroyed.Such as, panel TV set is in order to alleviate complete machine weight, and metal backing thickness used is generally 0.6～0.8mm,
The flange screwed hole strength ratio causing assembly ware is weaker；Operator assembles when, if screw enters the spiral shell of backboard
Pit slightly out of plumb is easy for damaging the stricture of vagina screw-socket of backboard, causes stripped thread, makes backboard scrap.
Existing screw mainly head of screw and screw rod by integral structure is constituted, and the end of screw rod is provided with taper guide part.Although
The taper guide part of screw rod end can play certain guide effect in the installation process of screw, but, due to screw rod end
The length of taper guide part generally the shortest, therefore guide effect is the best, easy misalignment during the sheet member fastened with existing screw
Screwed hole and be difficult to Uprightness adjusting, so that thread damage when screw is screwed into, causes the problems such as stripped thread, makes sheet member scrap.
Utility model content
This utility model provides a kind of screw being easily installed, it is intended to solve easy misalignment screwed hole when existing screw is installed
Problem.
This utility model solves its technical problem and be the technical scheme is that a kind of screw being easily installed, including screw body,
Described screw body mainly head of screw and screw rod by being connected together is constituted；This screw also includes guide rod；In described screw body
Being axially arranged with guide rod through hole along it, described guide rod is slidably disposed in guide rod through hole, and the length of guide rod is more than guide rod through hole
Length.
Further, described screw body also includes polished rod, and the diameter of described polished rod is less than the path of screw thread on screw rod, described
Head of screw and screw rod are linked together by polished rod.
Further, described head of screw, polished rod and screw rod are integral type structure.
Further, the lower end of described screw rod is provided with the guide part of taper.
Further, the upper end of described guide rod is provided with limiting section.
Further, the lower end of described guide rod is provided with the insertion section of taper.
The beneficial effects of the utility model are: when installing this screw, are inserted by the part that lower end of the guide rod passes screw body lower end
Enter in screwed hole, the most just make this screw be directed at screwed hole, and guide rod can be passed through by screw body Uprightness adjusting to prevent screw
Thread damage when tightening, and then avoid the problems such as stripped thread；Meanwhile, can also be avoided because arranging relatively in screw rod lower end by guide rod
Long guide part and cause the problem that screwed hole deepens.
Accompanying drawing explanation
Fig. 1 is enforcement structural representation of the present utility model；
Fig. 2 is connection status schematic diagram of the present utility model；
Figure is labeled as: screw body 100, head of screw 110, screw rod 120, guide part 121, polished rod 130, guide rod through hole
140, guide rod 200, limiting section 210, insertion section 220, spring washer 300, plain washer 400.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As it is shown in figure 1, a kind of screw being easily installed, including screw body 100 and guide rod 200；Described screw body 100
Mainly it is made up of the head of screw 110 being connected together and screw rod 120；Along the axle of screw body 100 in described screw body 100
To being provided with guide rod through hole 140, described guide rod 200 is slidably disposed in guide rod through hole 140, and the length of guide rod 200 is big
Length in guide rod through hole 140.Wherein, head of screw 110 and screw rod 120 usually integral structure；Guide rod through hole 140
Upper end is positioned at the top of head of screw 110, and the lower end of guide rod through hole 140 is positioned at the bottom of screw rod 120；The diameter of guide rod 200 is little
In the diameter of guide rod through hole 140, usual guide rod 200 and guide rod through hole 140 matched in clearance, i.e. guide rod 200 are arranged on guide rod and lead to
In hole 140 and can slide along guide rod through hole 140；The length of guide rod 200 is more than the length of guide rod through hole 140, the most permissible
After ensureing that guide rod 200 is arranged in guide rod through hole 140, its lower end can pass the lower end of screw body 100, in order to insert spiral shell
Pit guides.
Shown in Fig. 1 and Fig. 2, when installing this screw, by guide rod 200 lower end being passed the portion of screw body 100 lower end
Divide and insert in screwed hole, the most just make this screw be directed at screwed hole, and can be by guide rod 200 by screw body 100 vertical adjustment
Directly, then by screw body 100 pre-screwing, finally extract guide rod 200 and with screwdriver, screw body 100 is tightened again.
As in figure 2 it is shown, in order to prevent this screw from weighing product surface wounded, generally install plain washer 400 during connection on screw rod 120；For
Screw loosening during preventing from using, is also equipped with spring washer 300 on screw rod 120, and spring washer 300 is positioned at plain cushion
Between circle 400 and head of screw 110.
Concrete, then as it is shown in figure 1, described screw body 100 also includes that polished rod 130, the diameter of described polished rod 130 are less than
The path of screw thread on screw rod 120, described head of screw 110 and screw rod 120 are linked together by polished rod 130.Preferably, institute
Stating head of screw 110, polished rod 130 and screw rod 120 is integral type structure.
In order to further facilitate screw body 100 Uprightness adjusting, the lower end of described screw rod 120 is provided with the guide part 121 of taper.
In order to avoid when this screw is installed, guide rod 200 comes off from screw body 100, as depicted in figs. 1 and 2, described guide rod
The upper end of 200 is provided with limiting section 210.Guide rod 200 inserts the guide rod through hole 140 on screw body 100 for convenience, described in lead
The lower end of bar 200 is additionally provided with the insertion section 220 of taper.
