Abstract
The utility model discloses a check nut, this nut body (1) go up the symmetry and are equipped with two rather than axis vertically threaded through-hole (3), through-hole (3) in be equipped with through-hole (3) screw thread matched with holding screw (2). The anti-loosening effect of the anti-loosening nut is ideal and the structure is relatively simple.
Description
Technical field
The utility model relates to a kind of nut locking device, specifically is a kind of jam nut.
Background technique
Be installed in the nut on the bigger machinery of amplitude such as jumbo and the main equipment because be given a shock easy becoming flexible for a long time, thereby have influence on the normal operation of equipment, and can produce potential safety hazard.And some the nut locking devices or the locking effect as announcing on the State Intellectual Property Office website of prior art are not ideal, or the structure more complicated, operate loaded down with trivial details relatively.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of anti-loosing effect ideal and structure simple relatively jam nut.
Technical solution of the present utility model is, a kind of jam nut is provided, and is arranged with two threaded through holes with its (nut body) axis normal on this nut body, is provided with the Cock screw that matches with through hole whorl in the described through hole.
After adopting above structure, the utility model jam nut compared with prior art has the following advantages:
Cock screw is screwed in the through hole fully, make the Cock screw head be pressed on, strengthened the resistance of jam nut and bolt relative movement, make the locking fastening better effects if of jam nut by on the fastening bolt of nut; Because the utility model jam nut only manys two through hole and two Cock screws than original nut, structure is simple relatively, thus operate convenient relatively.
Description of drawings
Fig. 1 be the utility model jam nut face the broken section structural representation.
Fig. 2 is the side-looking broken section structural representation of the utility model jam nut.
Shown in the figure 1, nut body, 2, Cock screw, 3, through hole, 4, center line.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, be arranged with two threaded through holes 3 with the axis normal of nut body 1 on the nut body 1 of the utility model jam nut, be provided with Cock screw 2 in the described through hole 3 with through hole 3 threads engaged.Described symmetry is meant, the axis of two through hole 3 is positioned on same the center line 4 of nut body 1 and is vertical with wherein two side faces of nut body 1.The axis of described two through hole 3 is positioned in the middle of the thickness of this nut body 1.Described Cock screw 2 heads are 45 ° of nose cones.
Claims (3)
1, a kind of jam nut is characterized in that: be arranged with two threaded through holes (3) with its axis normal on this nut body (1), be provided with the Cock screw (2) with through hole (3) threads engaged in the described through hole (3).
2, jam nut according to claim 1 is characterized in that: the axis of described two through hole (3) is positioned in the middle of the thickness of this nut body (1).
3, jam nut according to claim 1 is characterized in that: the head of described Cock screw (2) is 45 ° of nose cones.
