The purpose of description specific embodiment, it is not intended that in limitation the utility model.
Referring to FIG. 1 to FIG. 4, it is a kind of spring fastener of one preferred embodiment of the utility model, including presses door 10, fastener
Main body 20, spring 40 and spring steel plate 50.
There is door fixing end 11 and door free end 14 by door 10；Two the have been extended outward to form on the end face of door fixing end 11
One fixed block 12, the end face of door fixing end 11 are equipped with the mounting hole 13 between the first fixed block 12.
Fastener main body 20 surrounds a unclosed fastener chamber 21；The end face of one end of fastener main body 20 is to fixing end 11 of answering the door
End face setting, and extended outward to form the second fixed block 22, the second fixed block 12 is pivotally connected the first fixed block by shaft 30
12, so that pressing door 10 can rotate relative to fastener main body 20, achieve the purpose that the opening for turning on or off fastener chamber 21；Second
Fixed block 22 is formed with limiting slot 23 towards the side of door fixing end 11；The other end of fastener main body 20 sets free end 14 of answering the door
It sets, abuts for door free end 14 fastener chamber 21 to be closed.In the present embodiment, the quantity of the first fixed block 12 is two,
Second fixed block 22 is inserted between the first fixed block 12, and is pivotally connected by shaft 30 and each first fixed block 12.
One end of spring steel plate 50 is inserted in the cavity that spring 40 surrounds, and the other end is inserted in limiting slot 23；Spring
Steel disc 50 is equipped with retention bead 51, and retention bead 51 is located at spring 40 close to the side of limiting slot 23, and supports spring 40, uses
Spring 40 is squeezed when rotating inward by door 10；The area of the cross section of spring steel plate 50 is greater than the wire that spring 40 is made
Cross section, and the thickness of spring steel plate 50 is greater than the diameter that the wire of spring 40 is made.It can be in 50 He of spring steel plate by door 10
It automatically resets under the collective effect of spring 40.
As shown in Figure 1, the first fixed block 12 is arranged far from the one end for pressing door 10 in arc-shaped, to avoid the first fixed block 12
Scratch fastener main body 20.
In other embodiments, self-lubricating layer can be set towards the side of the second fixed block 22 in the first fixed block 12, with
Frictional force between smaller first fixed block 12 and the second fixed block 22.
In the present embodiment, the first block machine 15 has been extended outward to form on the end face of door free end 14；Fastener main body 20 is leaned on
Corresponding first block machine 15 is equipped with the second block machine 26 on the end face of nearly door free end 14, the second block machine 26 be located at the first block machine 15 towards
The side of fastener chamber 21.When pressing door 10 and closing the opening of fastener chamber 21, the second block machine 26 abuts the first block machine 15, the first block machine
15 close rotating outward under the effect of external force again by door 10 for fastener chamber 21 for stopping.
As shown in Fig. 2, further, the first block machine 15 is equipped with locating slot 16 towards the side of the second block machine 26, second
The corresponding locating slot 16 of block machine 26 is equipped with positioning protrusion 27, and when closing fastener chamber 21 by door 10, positioning protrusion 27 is inserted in locating slot
In 16, shaking under the effect of external force along the axis direction of shaft 30 again by door 10 for fastener chamber 21 is closed for preventing.
In the present embodiment, the second fixed block 22, which has, is located at limiting slot 23 close to the first grafting of the side of fastener chamber 21
Portion 24 and positioned at limiting slot 23 close to the second plug division 25 of the side of fastener chamber 21, the first plug division 24 has towards limiting slot
23 the first face 241；Second plug division 25 has the second face 251 of limiting slot 23 of practising physiognomy, and the first face 241 is away from fastener chamber
21 direction is obliquely installed, and the direction of the second face 251 towards fastener chamber 21 is obliquely installed；Between first face 241 and the second face 251
Angle be greater than 35 °.In the present embodiment, the angle between the first face 241 and the second face 251 is preferably 37 °.
The end of first plug division 24 to shaft 30 distance less than the second plug division 25 end to shaft 30 distance,
This enables the distance of the second plug division 25 to the end face of door fixing end 11 when being closed fastener chamber 21 by door 10 less than the first grafting
The distance of portion 24 to the end face of door fixing end 11 just can after needing speed ratio larger angle when so that rotating inward by door 10
With the first plug division 24 with or without, increase the angular range rotated inward by door 10 so that press door 10 to
It was not easy dead-centre position when interior rotation, is not susceptible to phenomenon stuck after rotating by door 10.
Second plug division 25 is in arc-shaped close to one end of fixing end 11, and radius is 0.1mm~0.15mm.The size model
Enclosing can make the second face 251 very close to fastener chamber 21, so that thickness ratio of second plug division 25 close to one end of fixing end 11
It is smaller, so that the second plug division 25 does not have too many contact surface when contacting when spring steel plate 50 is bent with the second plug division 25
Product is bent so that biggish angle can occur when contacting for spring steel plate 50 and the second plug division 25, increase by door 10 to
The dead point angle of interior rotation, so that being not easy dead point position by the angle that door 10 is opened, so that being not easy to send out by door 10
The stuck phenomenon in dead point position was given birth to occur.
As shown in figure 4, the quantity of retention bead 51 is two, it is symmetrically set in the two sides of spring steel plate 50.
Spring steel plate 50 stretches to 2.5 times~3.5 times of the radius that the depth in spring 40 is mounting hole 13, this can make
Obtain spring steel plate 50 has bigger mobile space in limiting slot 23, is convenient for 50 compressed spring 40 of spring steel plate.
Above-mentioned spring fastener, combines by using spring steel plate 50 and spring 40, can spring 40 power energy is most of
It is transferred on spring steel plate 50, so that the elastic force of spring steel plate 50 be made to play the main role for making to reset by door 10, and spring 40
Elastic force play the role of making the auxiliary force resetted by door 10, it is smaller be damaged, be not easy so that spring 40 is not susceptible to fatigue
It is broken, and because the area of the cross section of spring steel plate 50 is greater than the area that the cross section of wire of spring 40 is made,
And the thickness of spring steel plate 50 is greater than the diameter of the wire of support spring 40, is not easy compared to spring steel plate 50 for spring 40
It is broken, it is therefore provided that the number of the pressing rebound of 40 spring fastener of spring also increases, extend spring fastener uses the longevity
Life.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
