TWM262605U - Improved fast engaging nut - Google Patents

Description

M262605 9. Creation instructions (1) [The creation of the new technology belongs to the fact that the ends of the spring flaps of the fast-fit nut can be penetrated into the thread. [Previous technology] Please refer to Figure " for the speed of the component combination. Very slow, the nut picks up a few revolutions, especially a very inconvenient but also a waste of time. Please refer to the second figure, one is provided with an elastic piece 30, the elastic piece 30 has an elastic piece petal 32, and the end face of the elastic petal 32 is not shown in the figure when the elastic petal 32 is used. As a result, the elastic flap 3 2 is disengaged from the thread. The flap 3 2 and the flange 3 1 are large and circular in shape by stamping. The moment of inertia is not easy and the stamping is difficult to affect the engagement with the screw 11. Content] The conventional fast combination nut has a circular arc shape and a large moment of inertia. When it is combined, it will cause rigidity and brittleness when it is elastically toggled. The nut has a good elasticity design, which is not easy to detach & the conventional screw 11 and secondary screw nut are often screwed in and loosened out. The convex section is always close to the elasticity and does not cause a card type. The value is larger and more fruitful. The fast edge 3 1 and the straight shape, the outer thread is good, or the solid fails; the elastic flap 3 2 improves the rigidity and elasticity, especially, and its elasticity. The nut 1 2 appears to fit the nut 20 when it must be screwed. It is arranged in a conical shape with 11 sets of screws and edges (such as when the third elasticity is fatigued. In addition, the elastic root width is relatively increased. The bending is relatively poor, which will result in a relatively wide rigidity of the root of the elastic flap, which requires a large amount of force. The stamping degree of the elastic flap is relatively large and the elasticity is poor. It is not easy to elastically deform and form.

Page 5 M262605 4. Creation Instructions (2) ~ This will affect the meshing effect with the screw. This creation provides an improvement of a fast-fitting nut. It should include a body. The receiving part in the body is used for receiving an elastic piece. The flange part of the elastic piece is placed on the bottom surface of the receiving part. Several elastic flaps arranged in a conical shape abut against the top edge surface of the conical convex body. The end surface of the body is tightly inserted into an end cap. The protruding end protruding from the end surface of the end cap abuts and fixes the flange of the elastic sheet; A through hole is provided between the elastic flap and the elastic flap to reduce the area of the root of the elastic flap in order to increase its elasticity. The end of the elastic flap is curved and can penetrate the root of the thread and the peripheral edge of the flange. There are several tiny and raised pawls that can be inserted into the body. This creation is an improvement of the fast-fitting nut. The design of the elastic piece by the pawl can grasp the body without the interference of external force, and it is not easy to disengage. The design of the curved end of the elastic valve can penetrate the root of the thread, and it is not easy to disengage. The design of the through hole of the root of the elastic valve reduces the length and area of the arc of the root and relatively reduces the moment of inertia to make bending easier. The elasticity can appropriately increase the sheet, not easy to fatigue and brittle, and the service life can be increased. The practicality and function of the nut. [Embodiment] Please refer to the fourth and fifth figures. This creation mainly includes a body 40, and there is no perforation 41 in the center of the body 40. A convex cone is set inside the body 40 and along the periphery of the through hole η Convex body 42. The accommodating part 43 in the main body 40 is used for accommodating an elastic sheet 50. The flange 51 of the elastic sheet 50 is placed on the bottom surface of the accommodating part 43. It is a unidirectional elastic sheet and is arranged in a conical shape. Each spring leaf petal 52 abuts on the top edge surface of the conical convex body 42 so that the spring leaf petal 52 can only spring open in one direction, and retract inward.

4. Creation instructions (3) The end surface of the end cap 60 is convex. Its main feature is the state. The end surface of the body 40 is tightly fitted into the end of the end cap 60. The fitting end 61 of the end cap 60 abuts and fixes the flange of the elastic sheet 50. A through hole 53 is provided between 51 and the elastic flap 52 to reduce the area of the root of the elastic flap 52 in order to increase its elastic effect. The end of the elastic 52 is curved, which can penetrate the root of the thread and the flange. The peripheral part of 51 is punched with several tiny and raised pawls 5m ′ (as shown in the fourth figure). § Quick fit description:

Please refer to the sixth figure *. The quick nut of this creation can be quickly inserted into the screw 11. The spring leaf flap 52 is pushed out by the screw and pushed outward: the screw 11 can quickly pass through; the screw u wants to reverse When pulled out, the end of the shrapnel will snap into the screw groove of the screw U and be fixed in place; for this purpose, the creation 2 can be quickly threaded into the screw core in one direction (as shown in Figure 7). Out to the spiral. §The shrapnel flap penetrates into the thread groove, and the meshing degree is very good. ☆ _Refer to Figure 78. The end of this creative elastic flap 5 2 is set with a curved arc, so it can be approached deeply when the thread is stuck. Root of thread

The part of the nipple is fitted, so the meshing degree between the elastic flap 52 and the thread is very good, and there is no fear of detachment. § Punching of the root of the shrapnel flap to improve the elasticity: Red, as shown in the fourth figure, the root of the elastic flap 52 is connected to the flange 51. The σ has a perforation 53 ', which makes the elastic flap 52's originally long root arc. The ugly area is also relatively reduced, the root arc is only two sides, and the moment of inertia is

M262605 Fourth, the creation description (4) is reduced, stamping becomes easier, and the elasticity is relatively improved. The elastic flap 52 is more elastic when it is fitted with the thread 11, and it is not easy to deform and brittle, and the service life is relatively improved. § Shrapnel uses pawl? It is difficult to fall off when holding the body. Please refer to Figures 4 and 7. As shown in Figures 4 and 7, the flange 5 1 of the spring piece 5 is punched with several tiny and upwardly raised pawls 5 n. The pawls 5 丨 1 are like needles. When combined like a body 40, will the pawl 51ι penetrate into the body 40? Stay, because the body 40 is made of plastic material, the texture is softer and the pawl 511 is easier to penetrate? Therefore, unless the external force is used to forcibly separate, the elastic piece 50 will not be easy to detach, which is more convenient for the assembly operation. Do n’t worry about the elastic piece 50 popping up or falling due to shaking during assembly. From the above description, it can be known that the structure of the fast-fitting nut of this creation is improved. The design of the elastic piece is not easy to detach in the body, the root of the elastic valve is not easy to detach, and the length and area of the arc of the elastic portion are relatively reduced. 'The elasticity can be appropriately raised, not to increase, so the structure of the new rapid fit is designed as an application element for fast fit, according to the law ^ The design of the end curve can be grasped without the interference of external forces. The design of the thread through-hole of the root of the petal reduces the moment of inertia of the root, making it easier to bend and fatigue and brittle, and the service life of the nut is more practical and functional. Special application.
