Abstract
The utility model provides an anti-loosening screw. The anti-loosening screw comprises a screw head and a screw rod, wherein the screw head is trapezoidal; a connecting piece is arranged between the screw head and the screw rod, and is provided with a retaining rib; and the screw rod is provided with a self-tapping thread. The utility model aims to design the anti-loosening screw which has the advantages that when the screw is embedded into and contacted with a fixed object, the screw can be prevented from falling off due to reasons such as machine vibration and the like, and the friction force of the screw can be enhanced; and due to the arrangement of the self-tapping thread, the screw can be inserted into an object more easily.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of screw of becoming flexible of preventing.
Background technique
Fastening piece is also referred to as standard piece in market, that two or more parts (or member) are fastenedly connected the general name that becomes class mechanical parts that adopt when whole, its feature is that description is various, the performance purposes is different, and standardization, seriation, unitized strong.Fastening piece is most widely used mechanical basic part, is in great demand.
Screw is a class fastening piece that is made of head and screw rod two-part, can be divided three classes by purposes: machine screw, Cock screw and specific use screw, machine screw is mainly used in the part of a clamp screw pit, and one with being fastenedly connected between the part of through hole, (this Connecting format is called screw and connects, and also belongs to removably connect not need the nut cooperation; Also can cooperate with nut, be used for two with being fastenedly connected between the part of through hole.) Cock screw is mainly used in fixing two relative positions between the part, the specific use screw is such as lifting bolt etc. being arranged for the lifting part.
Common screw is with object fixedly the time, if fixing or be subjected to the vibration of machine for a long time, the phenomenon that usually comes off causes the fault of machine, has affected the working life of machine.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of screw of becoming flexible of preventing, contact with fixture when screw embeds, can prevent that the reason such as machine vibration from making toner screw, can also strengthen the frictional force of screw, the setting of Thread Forming TF makes screw can more easily go deep into object.
The utility model provides a kind of screw of becoming flexible of preventing, the described screw that becomes flexible that prevents comprises screw head, screw rod, and described screw head is trapezoidal, is provided with link between described screw head and screw rod, be provided with the retaining muscle at described link, be provided with Thread Forming TF on the described screw rod.The purpose of this utility model design is a kind of to prevent the screw that becomes flexible, when embedding, screw contacts with fixture, can prevent that the reasons such as machine vibration from making toner screw, can also strengthen the frictional force of screw, the setting of Thread Forming TF makes screw can more easily go deep into object, this model utility is simple in structure, low cost of manufacture, and long service life.
The utility model discloses a kind of a kind of improvement that prevents the screw that becomes flexible, the setting that assumes diamond in shape of described retaining muscle, described retaining muscle is projection outwards.This improved purpose is to prevent toner screw, and screw can more easily be fixed on the object.
The utility model discloses a kind of a kind of improvement that prevents the screw that becomes flexible, described retaining muscle is arranged on the link periphery, and described retaining muscle is at least 3.This improved purpose is strengthen screw fixing, prevents toner screw, prolongs the working life of screw.
The purpose of this utility model design is a kind of to prevent the screw that becomes flexible, when embedding, screw contacts with fixture, can prevent that the reasons such as machine vibration from making toner screw, can also strengthen the frictional force of screw, the setting of Thread Forming TF makes screw can more easily go deep into object, this model utility is simple in structure, low cost of manufacture, and long service life.

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand following embodiment and only be used for explanation the utility model and be not used in restriction scope of the present utility model.Need to prove, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in the accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of particular elements geometrical center.
Embodiment 1:
As shown in Figure 1, the utility model provides a kind of screw of becoming flexible of preventing, the described screw that becomes flexible that prevents comprises screw head 11, screw rod 31, described screw head 11 is trapezoidal, between described screw head 11 and screw rod 31, be provided with link 21, be provided with retaining muscle 51 at described link 21, be provided with Thread Forming TF 41 on the described screw rod 31.The purpose of this utility model design is a kind of to prevent the screw that becomes flexible, when embedding, screw contacts with fixture, can prevent that the reasons such as machine vibration from making toner screw, can also strengthen the frictional force of screw, the setting of Thread Forming TF makes screw can more easily go deep into object, this model utility is simple in structure, low cost of manufacture, and long service life.
Embodiment 2:
The setting that assumes diamond in shape of the described a kind of screw that becomes flexible of preventing of embodiment 1, described retaining muscle 51, described retaining muscle 51 is projection outwards.This improved purpose is to prevent toner screw, and screw can more easily be fixed on the object.
Embodiment 3:
The described a kind of screw that becomes flexible of preventing of embodiment 2, described retaining muscle 51 is arranged on link 21 peripheries, and described retaining muscle 51 is at least 3.This improved purpose is strengthen screw fixing, prevents toner screw, prolongs the working life of screw.
The purpose of this utility model design is a kind of to prevent the screw that becomes flexible, when embedding, screw contacts with fixture, can prevent that the reasons such as machine vibration from making toner screw, can also strengthen the frictional force of screw, the setting of Thread Forming TF makes screw can more easily go deep into object, this model utility is simple in structure, low cost of manufacture, and long service life.
The above; it only is preferred embodiment of the present utility model; be not to be the restriction of the utility model being made any other form, and according to any modification or equivalent variations that technical spirit of the present utility model is done, still belong to the utility model scope required for protection.
