Abstract
The utility model provides a connecting piece of a hexagonal head bolt and a nut. The connecting piece of the hexagonal head bolt and the nut comprises the bolt and the nut matched with the bolt. The bolt comprises a bolt head and a screw. The end portion of the screw is provided with threads matched with the nut. An annular sleeve is sleeved on the screw. At least two elastic pieces are arranged on the annular sleeve in an annular mode. The connecting piece of the hexagonal head bolt and the nut can effectively solve the problem that the bolt rocks in a through hole. The nut and the bolt do not loosen easily. The connecting piece of the hexagonal head bolt and the nut is high in safety performance.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of hexagon head bolt, screw connector.
Background technique
Bolt is by a head and a screw rod class link dimerous, screw rod is for having externally threaded cylindrical body, need to cooperate with nut, be used to be fastenedly connected two parts that have through hole, this Connecting format claims bolt to connect, nut being screwed off from bolt, can make these two parts separately again, is to belong to removably connect so bolt connects.The head of bolt has hexagonal, circle, square etc., and hexagon head is the most common.Existing bolt owing between through hole and the bolt space is arranged, causes bolt to rock in through hole when passing the through hole that length is bigger, and is special under the situation of mechanical shock, is easy to cause the loosening of nut and bolt, thereby brought certain potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of hexagon head bolt, screw connector, can solve the problem that bolt rocks in through hole effectively, and nut and bolt are difficult for loosening, the Safety performance height.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of hexagon head bolt, screw connector, comprise bolt, with the bolt nut engaged, described bolt comprises bolt head and screw rod, the end of described screw rod is provided with the screw thread that cooperates with nut, be with ring set on the described screw rod, be equipped with at least two shell fragments on the described ring set.
As preferably, described shell fragment adopts two, and symmetrical ring is located on the ring set.Guaranteed effectively to have avoided bolt to rock to the symmetry properties of the support of the through-hole wall of screw rod both sides.
As preferably, the outer wall of described screw rod is equipped with the blend stop of at least one retaining T-Ring cover.Realized qualification, avoided ring set arbitrarily to move the position of ring set.
As preferably, described blend stop adopts three, and uniform ring is located at the outer wall of screw rod.Make simply, reduced manufacture cost.
As preferably, be with the packing ring that is abutted against bolt head on the described screw rod.Increased the area of contact between bolt head and the through hole, reduced the pressure of bolt head, through hole has been played a protective role through hole.
Beneficial effect:
The utility model adopts technique scheme that a kind of hexagon head bolt, screw connector are provided, be with ring set on the screw rod of bolt, be equipped with at least two shell fragments on the described ring set, realized effective support to the through-hole wall in the screw rod outside, solve the problem that bolt rocks effectively in through hole, nut and bolt are difficult for loosening, the Safety performance height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of hexagon head bolt, screw connector, comprise bolt 1, with bolt 1 nut engaged 2, described bolt 1 comprises bolt head 11 and screw rod 12, the end of described screw rod 12 is provided with the screw thread 13 that cooperates with nut 2, be with ring set 3 on the described screw rod 12, be equipped with at least two shell fragments 4 on the described ring set 3.Described shell fragment 4 adopts two, and symmetrical ring is located on the ring set 3.The outer wall of described screw rod 12 is equipped with the blend stop 5 of at least one retaining T-Ring cover 3.Described blend stop 5 adopts three, and uniform ring is located at the outer wall of screw rod 12.Be with the packing ring 6 that is abutted against bolt head 11 on the described screw rod 12.
During real work, ring set 3 is socketed on the screw rod 12, utilize blend stop 5 retaining T-Ring covers 3, then screw rod 12 is stretched in the through hole, fastening nut 2 gets final product, and the shell fragment 4 on the ring set 3 has been realized effective support of the through-hole wall in screw rod 12 outsides is solved the problem that bolt rocks effectively in through hole, nut and bolt are difficult for loosening, the Safety performance height.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
