Abstract
The utility model provides an outward pulling type self-locking bolt, and relates to a self-locking bolt. A rotary screwing head (1) is arranged on the upper portion of the bolt, external threads (2) are arranged on the outer edge face of a rod body on the lower portion of the rotary screwing head (1), and a penetrated internal thread hole (9) is arranged from the upper end face of the rotary screwing head to the lower end face of the rod body. A cylinder (8) is arranged at the lower end of a threaded rod (7), and a rotary screwing end (6) is arranged at the upper end of the threaded rod. An annular cavity is formed in a glue sleeve of a circular ring structure, and weather-proof sealant (5) is arranged in the annular cavity. A middle hole (4) of the glue sleeve is sleeved on a position, close to the cylinder, of the threaded rod, the threaded rod is penetrated in the internal thread hole of the bolt, and the rotary screwing end of the threaded rod is exposed on the upper portion of the rotary screwing head of the bolt. When the outward pulling type self-locking bolt is used, the glue sleeve is sleeved on the threaded rod, the weather-proof sealant is injected into the glue sleeve, after the bolt is connected with a connecting piece, the cylinder is driven through the rotary screwing end of the threaded rod, the cylinder compresses the glue sleeve, the weather-proof sealant is filled in the end portion of the bolt, and because thick weather-proof sealant forms resistance, the bolt is locked on the connecting piece.
Description
[technical field]
The utility model relates to a kind of self-locking screw, and specifically the utility model relates to a kind of outer drawing type self-locking screw.
[background technique]
Known, a lot of links are by bolted in machinery, haulage vehicle, railway and highway bridge, steel frame construction building, because in equipment operation, can produce huge amplitude, during advancing, haulage vehicle is in vibrating state always, railway and highway bridge also can be subjected to the influence of vehicular traffic and vibrations occur, the steel frame construction building also can be subjected to the various factors influence and vibrations occur, because above-mentioned shock-effect problem, feasible bolt as connection occurs easily coming off and influences safety; Self-locking screw kind in market sale is more, employed technological scheme is on the screw thread of bolt locking mechanism to be set, also there are the spring sheet of use or rubber to form locking " self-locking ", but be subjected to erosion by wind and rain and vibrations for a long time, spring sheet just can fatigue occur and lose auto-lock function, especially Luo Lu rubber is in case the tired or aging auto-lock function that just loses, auto-lock function forfeiture phenomenon also can appear in the obstruction that the self-locking screw that locking mechanism is set on the described screw thread is subjected to rusty stain behind the rain erosion and dust, and can't discover; Be subjected to the influence of above-mentioned factor, all there is potential safety hazard in existing self-locking screw.
[model utility content]
In order to overcome the deficiency in the background technique, the utility model discloses a kind of outer drawing type self-locking screw, when using, the utility model is enclosed within on the screw rod by the gum cover that inside is injected with weather-resistant glue, being arranged in the bolt of screw rod, after bolt and link connected, the end of screwing by screw rod drove cylinder, by cylinder compressing gum cover, make weather-resistant glue be filled in the bolt end, because the weather-resistant glue of thickness forms resistance, described bolt just is locked on the link.
In order to realize the purpose of this utility model, the utility model adopts following technological scheme:
A kind of outer drawing type self-locking screw comprises bolt, screw rod and gum cover, and described bolt top is set to screw head, is outside thread at the lower pole body outer edge surface of screwing head, is provided with the interior threaded hole of perforation to body of rod lower end surface by the upper-end surface of screwing head; Lower end at screw rod is provided with cylinder, screws the upper end that end is arranged on described screw rod; Gum cover is a cirque structure, is ring cavity in the described cirque structure gum cover, is provided with weather-resistant glue in ring cavity; The mider hole of gum cover is enclosed within the close cylinder place of screw rod, and screw rod is through in the interior threaded hole of bolt, and a top of screwing that exposes at bolt is held in screwing of described screw rod.
Described outer drawing type self-locking screw, the outer wall of described gum cover is provided with the hole, and described hole is the weather-resistant glue hand-hole.
Described outer drawing type self-locking screw, the outer edge surface of cylinder is slightly less than the outside thread of bolt.
Described outer drawing type self-locking screw, the end of screwing of described screw rod is square or hexagonal structure.
By above-mentioned disclosure, the beneficial effects of the utility model are:
Outer drawing type self-locking screw described in the utility model, be enclosed within on the screw rod by the gum cover that inside is injected with weather-resistant glue during use, being arranged in the bolt of screw rod, after bolt and link connect, the end of screwing by screw rod drives cylinder, by cylinder compressing gum cover, make weather-resistant glue be filled in the bolt end, because the weather-resistant glue of thickness forms resistance, described bolt just is locked on the link, can guarantee the safe operation of equipment, vehicle, guarantee the Security of railway and highway bridge, steel frame construction building, take precautions against the generation of bolt falling phenomenon effectively.
