Abstract
The utility model discloses a locking bolt, which comprises a bolt head (1) and a screw integrated with the bolt head (1), wherein the screw comprises a polished rod (2) and a threaded rod (3); the diameter of the polished rod (2) is greater than the major diameter of the threaded rod (3); the thread part of the threaded rod (3) is coated with anti-loose glue (4); and the area of the anti-loose glue (4) is less than that of the thread part of the threaded rod (3). The locking bolt has the advantages of good locking effect, simple assembly and low processing cost.
Description
Technical field:
The utility model relates to a kind of chek bolt.
Background technique:
As everybody knows, as a kind of fastening piece, metal bolts is easy to produce loosening or off line when being subjected to impact endurance test shock, at present, traditional mechanical lock solid method has two kinds usually, a kind of method is to increase running torque by the screw thread form that changes bolt, thereby produces the tensioner effect, reaches locking purpose; Another kind method is to make the part screw thread on the bolt counterpart nut produce axial displacement by pressure processing, thereby reaches locking purpose.Through facts have proved, there is the shortcoming of difficulty of assembling in preceding a kind of method, and there is the high shortcoming of processing charges in then a kind of method.
The model utility content:
Technology to be solved in the utility model is to provide a kind of anti-loosing effect better, and assemble the chek bolt simple, that processing cost is low to topic.
Technical solution of the present utility model is, a kind of chek bolt with following structure is provided, it comprise bolt head and with bolt head be holistic screw rod; Described screw rod comprises polished rod and threaded stem; The diameter of described polished rod is greater than the Major Diam of threaded stem; Scribble locking glue on the spiro tooth part of described threaded stem; The area of described locking glue is less than the spiro tooth part area of threaded stem.
After adopting above structure, compared with prior art, the utlity model has following advantage: because the locking glue after solidifying can form tough plasticity glued membrane in thread pitch, thereby the utility model can not become flexible, reached anti-loosing effect preferably after locking.Because the utility model both need not to change the screw thread form of bolt, also need not make the part screw thread on the bolt counterpart nut produce axial displacement by pressure processing, therefore, the utility model not only assembles simply, and processing cost also reduces greatly.In addition, because the area of locking glue described in the utility model, therefore, is guaranteeing under the situation about can not become flexible after the locking that the utility model can also prevent to make troubles for later dismounting because of excessively locking less than the spiro tooth part area of threaded stem.
As a kind of improvement of the present utility model, described locking glue can adopt anaerobic adhesive.Because described anaerobic adhesive has advantages such as viscosity is strong, heat-resisting, withstand voltage, low temperature resistant, pollution-free, price is low, therefore, the employing of anaerobic adhesive can further reduce processing cost of the present utility model when further strengthening the utility model anti-loosing effect.
Description of drawings:
Accompanying drawing is the structural representation of the utility model backing-up screw.
Locking glue as shown in the figure, 1, bolt head, 2, polished rod, 3, threaded stem, 4.
Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in drawings, in this specific embodiment, the utility model chek bolt comprises round end hexagon socket head cap screw head 1 and is holistic screw rod with bolt head 1; Described screw rod comprises polished rod 2 and threaded stem 3; The diameter of described polished rod 2 is greater than the Major Diam of threaded stem 3; Scribble locking glue 4 on the spiro tooth part of described threaded stem 3; The area of described locking glue 4 is less than the spiro tooth part area of threaded stem 3. and in this specific embodiment, described locking glue 4 is anaerobic adhesive.
Claims (2)
1. chek bolt, it comprise bolt head (1) and with bolt head (1) be holistic screw rod; Described screw rod comprises polished rod (2) and threaded stem (3); The diameter of described polished rod (2) is characterized in that greater than the Major Diam of threaded stem (3): scribble locking glue (4) on the spiro tooth part of described threaded stem (3); The area of described locking glue (4) is less than the spiro tooth part area of threaded stem (3).
2. backing-up screw according to claim 1 is characterized in that: described locking glue (4) is anaerobic adhesive.
