Abstract
The utility model relates to a double-groove locking device, comprising a 90 DEG latch pin and a double-groove thread sleeve. Holes in the thread sleeve are step-shaped, and two grooves are symmetrically disposed at the excircle of the thread sleeve. One end of the latch pin is in the shape of a right angled triangle, and the other end is flat. The width of a flat face is larger than that of each face of the triangle. The width of two right-angle faces of the triangle is smaller than or equal to that of a thread sleeve groove, and the width of the flat face is larger than that of the thread sleeve groove. In terms of assembling, the thread sleeve is firstly placed in a body made from steel or aluminum to be connected, and the right-angle face of the 90 DEG latch pin is inserted in the groove of the thread sleeve. The utility model is advantageous in that as the latch pin cooperates with the thread sleeve at an angle of 90 DEG, and the area of the latch pin cooperating with the thread sleeve is large, the fastening is good and the locking capability is strong, the double-groove locking device can be widely applied in the connection of bodies made from steel or aluminum when the extraneous vibration is quite large.
Description
Technical field:
The utility model relates to a kind of connection set, particularly relates to the connection spiral type double flute locking device of being with auto-lock function.
Background technique:
The use of steel-wire screw-socket is very general, and structure is also varied, and it is to realize locking by tightness cooperation, screw-thread fit etc. that the ordinary steel wire swivel nut is installed, and is short of tightness on locking device.During as link, when the external influence vibrations were big, its lock ability was poor, and the element precision of using is had relatively high expectations in being used for bodies such as steel, aluminum for this kind steel-wire screw-socket, and improper use easily causes part to scrap again.
Summary of the invention:
1, the technical issues that need to address
The utility model is at the deficiency of traditional steel-wire screw-socket, and by the mechanism to the double flute locking device, physical dimension and distortion etc. is analyzed, and has designed a kind of double flute locking device.
2, design proposal
Double flute locking device described in the utility model is made up of stop pin and double flute swivel nut two-part, and the hole of swivel nut inside is step-like, and symmetry has two troughs on the swivel nut cylindrical; Stop pin one end is 90 ° of right angle trigonometry shapes, the other end is flat, the width of flat horizontal surface is greater than the width of each face of gore, and the width of triangle two right angle faces is less than or equal to the width of swivel nut groove width, flat horizontal surface greater than the swivel nut groove width, forms the trapezoidal faces of transition between right angle trigonometry face and the flat horizontal surface.During assembling, earlier swivel nut is placed in the bodies such as steel to be connected, aluminum, triangle right angle face with 90 ° of stop pin inserts in the trough of swivel nut then, because stop pin becomes 90 ° of angles to cooperate with swivel nut, and stop pin cooperates the area of swivel nut bigger, so select the swivel nut of double flute not only can guarantee coupling mechanism force, can also reach the reasonable utilization of stop pin.
3, beneficial effect
Checking by test proves that double flute locking device structure tightness described in the utility model is good, and strong locking ability can apply to the connection of matrixes such as the bigger steel of external influence vibrations, aluminum more widely.
Description of drawings:
Fig. 1: be double flute locking device installation diagram.
Fig. 2: be trough of belt swivel nut left view.
Fig. 3: be trough of belt swivel nut figure sectional view.
Fig. 4: be 90 ° of stop pin figure plan views.
Fig. 5: be 90 ° of stop pin worm's eye views.
Among the figure: 1-90 ° of stop pin, the 2-swivel nut, 3-connects housing, the width on b-90 ° of stop pin inclined-plane.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Now the utility model is applied to the connection of steel shell class part, as shown in Figure 1, among the figure, be fixed in the housing 3 with the swivel nut 2 that has double flute, then locking stop pin 1 packed in the trough between swivel nut 2 and the housing 3, during assembling, guarantee that the triangular portions of stop pin 1 inserts in the groove of swivel nut 2, to form the entity angle, eliminate and rotate, realize stable mechanical self-latching.Stressed down at the flat horizontal surface of stop pin 1, the groove of transition trapezoidal faces on body, loosening when guaranteeing that housing 3 connects, should be screwed into that to insert stop pin 1 again behind the housing 3 fixing.After inserting stop pin 1, the one side of swivel nut just is fixed, and effectively works thereby more help another side, has avoided swivel nut to use under the strong motion environment and has occurred rotating.
The utility model is fine to have solved swivel nut in that fit on is easily loosening, tightness is bad, be unfavorable for problem such as dismounting maintenance, has improved functional reliability, and design is exquisite more, reasonable, has also improved assembling, the maintenance efficiency of housing, reduction expense.Simultaneously can form series standard, be convenient to promote the use of.
Claims (3)
