Abstract
The utility model relates to the field of hardware parts, in particular to a fixed anti-looseness component. The fixed anti-looseness component comprises a bolt, a connecting clamping barrel, a wedged gasket and a nut, wherein the bolt and the connecting clamping barrel are clamped and positioned; the connecting clamping barrel and the wedged gasket are clamped and positioned; a wedge groove is formed on the front side through which the wedged gasket is connected with the nut; and a wedge block matched with the wedge groove is arranged on the nut. According to the fixed anti-looseness component, the bolt is connected with the connecting clamping barrel, the connecting clamping barrel is connected with the wedged gasket, and the wedged gasket is connected with the nut, so that the nut is fixedly connected with the bolt through the connecting clamping barrel and the wedged gasket, and the aim of the shock looseness prevention is fulfilled. The condition that a common bolt is used on high-shock equipment and is easily loosened is effectively avoided, stable operation of the equipment is guaranteed, a threaded part of the bolt is protected by the connecting clamping barrel, the safety performance is improved, the fixed anti-looseness component is simple in structure and low in construction cost, and the labor intensity is lightened during periodic inspection.
Description
Technical field
The utility model relates to hardware part field, relates in particular to a kind of fixedly retention device.
Background technique
Existing checknut connection part generally adopts compression spring, and its effect is that screw thread and the flank of thread on the screw rod on the nut are compressed to increase frictional force each other, and this is enough for the fastening effect under the common working condition; But in high tenacity, for a long time vibrate under the operating mode be threaded then not competent; Simultaneously, plain bolt is when vibration equipment, and bolt thread is constantly impacted and rubs; The bolt that makes is more and more thinner; Not only bolt strength descends, and the bolt play, causes the functions of the equipments precise decreasing.For example, being threaded on the shaker vibration device just is easy to loosening and comes off, and this will cause vibrator and vibrating sieve is loosening and the danger of disengaging, has a strong impact on the equipment ordinary production.Taked between the bolts and nuts in the existing checknut connection part not realize having reduced contact surface on the contrary but its nut and workpiece surface of contact have against moving back effect against moving back sawtooth; Reduced very big friction factor in theory; Screw thread damages more easily, forms the gap, influences the functions of the equipments precision; So move back the more easy certainly pine of the occasion of height vibration, can't use.
Summary of the invention
The utility model technical problem to be solved provides a kind of fixedly retention device; Nut and bolt are inserted into pad through connecting card tube and form a fixed connection; Thereby realize the purpose that vibrations are locking, the equipment that has effectively solved in the height vibration uses plain bolt to be prone to loosening situation.
The utility model is achieved in that a kind of fixedly retention device; Comprise bolt, connecting card tube, wedging formula pad and nut, said connecting card tube center is a through hole, and said bolt head is provided with the screw thread that matches with nut; Bolt passes connecting card tube and links to each other with nut; Said wedging formula pad is arranged between connecting card tube and the nut, clamping location between said bolt and the connecting card tube, clamping location between said connecting card tube and the wedging formula pad; The front that wedging formula pad links to each other with nut is provided with wedge slot, and nut is provided with the voussoir that matches with wedge slot.
Described voussoir has two, and the center is symmetricly set on the nut.
The angle that is inserted into of described voussoir is 5 ~ 30 degree.
The angle that is inserted into of described voussoir is 15 degree.
The utility model fixedly bolt in the retention device is connected with connecting card tube; Connecting card tube is connected with wedging formula pad; Wedging formula pad is connected with nut, makes nut and bolt be inserted into pad through connecting card tube and forms a fixed connection, thereby realize the purpose that vibrations are locking.The equipment that has effectively solved in the height vibration uses plain bolt to be prone to loosening situation, has guaranteed the stable operation of equipment, and connecting card tube also plays a protective role to the helical thread portion of bolt simultaneously; Improved Safety performance; Simple in structure, cheap, alleviated labor intensity for making regular check on.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, a kind of fixedly retention device comprises bolt 1, connecting card tube 2, wedging formula pad 3 and nut 4; Said connecting card tube 2 centers are through hole; Said bolt 1 head is provided with the screw thread that matches with nut 4, and bolt 1 passes connecting card tube 2 and links to each other with nut 4, and said wedging formula pad 3 is arranged between connecting card tube 2 and the nut 4; Clamping location between said bolt 1 and the connecting card tube 2; Clamping location between said connecting card tube 2 and the wedging formula pad 3, wedging formula pad 3 is provided with wedge slot with the front that nut 4 links to each other, and nut 4 is provided with the voussoir that matches with wedge slot.
Like Fig. 2,3,4, shown in 5; The utility model can further describe into, said connecting card tube 2 one ends are provided with a pair of projection, connecting card tube 2 the other ends are that the center annular array has 4 grooves with the axle center of connecting card tube 2; The upper base surface of bolt 1 is provided with the pressing groove that matches with projection; The back side that said wedging formula pad 3 links to each other with connecting card tube 2 is provided with the fixture block that matches with groove, and described voussoir has two, and the center is symmetricly set on the nut 4.In the utility model, for the impacting force that guarantees to wedge, the angle that is inserted into of described voussoir is 5 ~ 30 degree, and in the present embodiment, the angle that is inserted into of described voussoir is 15 degree.
When the utility model is used to connect two connected pieces 5 in installation; At first that the wedging position of nut 4, wedging formula pad 3, connecting card tube 2 and bolt 1 is corresponding; Fastening nut 4 then, under the effect of stress, the voussoir of nut 4 snapped in the wedge slot of wedging formula pad 3 with 15 degree; At this moment the pressing groove of wedging fixture block and the bolt 1 of formula pad 3 also snaps in the groove and the projection of connecting card tube 2 respectively; This assembly must be selected suitable wedging formula pad 3 thickness according to the thickness of connected piece 5 adding man-hour, guarantees that nut 4 and wedging formula pad 3 can just be inserted under certain tight power effect, thereby realizes the purpose that vibrations are locking.
