Abstract
The utility model discloses a plug spring bolt, including hand (hold), bolt, pin, shell, spring and control tube, the pin is installed to the bolt to with hand (hold) threaded connection, be provided with open slot no. 1 and open slot no. 2 on the shell, shell and regulation pipe thread connection. The bolt is the cross shape, puts the spring in its step department, and the bolt lower part is the bulb form. The open slot is made a comparison of the open slot is two shallow. Compared with the prior art, this spring bolt simple structure, preparation convenience, the spring force size of both having guaranteed spring bolt is adjustable, can improve spring bolt's life again.
Description
Technical field
The utility model relates to hardware fitting field, particularly relates to a kind of night bolt.
Background technique
At present, in hardware fitting market, often night bolt can be touched, and the basic functional principle of this kind of night bolt is all rely on the resiliently deformable of spring to change the position of latch, reaches the parts that fixing spring latch connects.But this night bolt uses repeatedly continually, the antifatigue of spring and the coefficient of stiffiness can be caused to decline, elastic force declines thereupon, the resiliently deformable of spring is affected, thus affects the normal work of night bolt, even cannot reset, the night bolt can only changed spring or again more renew, so, the utilization rate of night bolt reduces greatly, causes the wasting of resources.
Model utility content
Technical problem to be solved in the utility model is: in order to ensure night bolt normally use and spring force size adjustable, can improve again the working life of night bolt, therefore, spy devises a kind of night bolt.
For solving the problems of the technologies described above, technical solution of the present utility model is: a kind of slotting spring latch, comprises hand handle, latch, shell and spring, it is characterized in that: described latch is provided with pin, and with described hand being threaded; Described shell is provided with opening slot one and opening slot two, described shell is threaded with adjutage.
A kind of night bolt, is characterized in that: described latch is cross shape, at its step place cover upper spring.
Described latch bottom is bulb shape.
Described opening slot one is more shallow than described opening slot two.
After adopting such scheme, the beneficial effects of the utility model are:
This night bolt structure is simple, easy to make; Both ensure that the spring force size of night bolt was adjustable, the working life of night bolt can have been improved again.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
What the utility model disclosed is a kind of slotting spring latch, as shown in Figures 1 to 5, is preferred embodiment of the present utility model.This night bolt comprise hand 1, latch 2, pin 3, shell 4, spring 5 and adjutage 6.
Described latch 2 is provided with pin 3, and is threaded 1 with described hand; Described shell 4 is provided with opening slot 1 and opening slot 2 42, described shell 4 is threaded with adjutage 6.Rotate adjutage 6, spring 5 will be squeezed, the rebounding force size that the tightness of spring 5 produces is along with change, so when the elastic force of night bolt reduces, only need to rotate adjutage 6 to certain position, the function of its night bolt is got back recovery, thus improves the working life of night bolt.
Described latch 2 is cross shape, at its step place cover upper spring 5, then puts adjutage 6 again, makes its latch 2 and spring 5 can be entrenched in the inside.
Described latch 2 bottom can be bulb shape, its objective is better chimeric with the position, hole of wanted build-up member.
Described opening slot 1 can be more shallow than described opening slot 2 42, is used to the screens of pin 3 on the one hand, thus ensure that the positioning action of latch 2; On the other hand, ensure that the degree of depth that latch 2 Lower Half is exposed when pin 3 is entrenched on opening slot 1 and opening slot 2 42 two positions is respectively different, thus reach the effect of fixed component and separating component, meet the fundamental function of night bolt.
During use, as shown in Figure 6, a kind of night bolt of the utility model is fixed on parts 1 by fitting seat 73, when pin 3 is entrenched on opening slot 2 42, namely latch 2 Lower Half is entrenched in the endoporus of parts 2 74, the degree of depth entered and dynamics can regulate by rotating adjutage 6, make parts 1 be fixed spacing firmly by it, so just cannot rotate under the effect of hinge 71.
As shown in Figure 7, pin 3 is made to be entrenched on opening slot 1 when hand is up mentioned 1 and rotated, at this moment, the Lower Half of latch 2 has departed from the endoporus of parts 2 74, and at this moment, parts 1 just can have rotated under the effect of hinge 71, when night bolt uses repeatedly, spring 5 meeting lost its bounce gradually, at this time also can regulate by rotating adjutage 6, ensureing the functional realiey of night bolt.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model to be imposed any restrictions, therefore the change in every case done according to claim of the present utility model and specification or modification, all should belong within scope that the utility model patent contains.
