Abstract

The utility model discloses a fast locking eccentric handle device with a lock, and aims to provide a fast locking device, which has the advantages of simple structure and fast and rapid locking, and the handle loosening or locking failure can not be caused due to product vibration under impact or the carelessness of the user. The fast locking eccentric handle device comprises a pull rod (5), a cylindrical pin (6) and an eccentric handle (8); wherein, the inside of an inner hole of the eccentric handle (8) is provided with a positioning pin (7), a drawing block (9) and a compression spring (10); the drawing block (9) is connected with one end of the positioning pin (7); the compression spring (10) respectively props against the lower end of the positioning pin (7) and the bottom of the inner hole of the eccentric handle (8); and the axial head of the pull rod (5) is also provided with a groove which matches the positioning pin (7). The utility model can be widely used in various fields which require fast locking, repeated tripping and prevention of accidental loosening.

Description

A kind of eccentric handle device of quick locking belt self-locking

Technical field

The utility model relates to a kind of eccentric handle device of quick locking belt self-locking.

Background technique

In the various fields of daily life and work, the structure of locking repeatedly, freeing between parts and the parts is seen everywhere, after the eccentric handle locking device is applied, make these structures that need lock repeatedly, free summary more, and make operation more fast, convenient; Yet in application practice, defective and deficiency that the eccentric handle locking device of prior art exists reveal gradually, thereby be difficult to requirement that satisfy to use, existing eccentric handle locking device, owing to there is not self-locking mechanism, what product was hit vibration or user causes the loosening locking of handle malfunctioning and cause security incident because of carelessness easily, all has potential safety hazard as the quick locking of bicycle saddle, the quick locking of various firearms accessories etc.

The model utility content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, locking is quick and convenient, can not cause the eccentric handle device of the not firm or quick locking belt self-locking that gets loose fully of locking because external force or user pull eccentric handle because of carelessness.

The technological scheme that the utility model adopted is: the utility model comprises locking nut, packing ring, body, briquetting, pull bar, straight pin and eccentric handle, described nut, packing ring matches with described pull bar, described pull bar and described eccentric handle position and are assembled into one by described straight pin, be provided with locating stud in the endoporus of described eccentric handle, stir piece, stage clip, describedly stir the end that piece is connected described locating stud, described stage clip withstands on the bottom of the endoporus of the lower end of described locating stud and described eccentric handle respectively, the spindle nose of described pull bar is provided with the groove that the top with described locating stud matches, described briquetting is realized locking by the described eccentric handle of rotation, and described eccentric handle advances the groove of described pull bar to realize self-locking described locating stud by described stage clip.

Described stirring between piece and the described locating stud is threaded.

The beneficial effects of the utility model are: owing to be provided with locating stud in the endoporus of eccentric handle described in the utility model, stir piece, stage clip, the spindle nose of described pull bar is provided with the groove that the top with described locating stud matches, therefore, when locking, eccentric handle is down rotated the locking of implement device, simultaneously during the groove corresponding position of locating stud on the spindle nose that forwards to pull bar, locating stud is subjected to the elastic force effect of stage clip, boost and match with groove on the pull bar spindle nose, realize self-locking thus, in the process of using,, reach quick with regard to not making the fixing insecure even phenomenon that comes off of locking device because of the vibration that is difficult to avoid and collision or user careless, convenient, the locking effect of safety.

Described stirring between piece and the described locating stud is threaded, and therefore in the process of using, can also control the self-locking degree by threaded adjusting.

Fig. 2 is vertical cut-away view of the utility model locking state;

Fig. 3 is the horizontal cut-away view that the utility model is removed locking state;

Fig. 4 is vertical cut-away view that the utility model is removed locking state.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises locking nut 1, packing ring 2, body 3, briquetting 4, pull bar 5, straight pin 6 and eccentric handle 8, described nut 1, packing ring 2 cooperates with described pull bar 5, described pull bar 5 positions and assembles by described straight pin 6 with described eccentric handle 8, and described straight pin 6 is as the rotatingshaft of described eccentric handle 8, be provided with locating stud 7 in the endoporus of described eccentric handle 8, stir piece 9, stage clip 10, describedly stir the end that piece 9 is connected described locating stud 7, described stage clip 10 withstands on the bottom of the endoporus of the lower end of described locating stud 7 and described eccentric handle 8 respectively, and the spindle nose of described pull bar 5 is provided with the groove that the top with described locating stud 7 matches.

Described stirring between piece 9 and the described locating stud 7 is threaded.

Step was as follows when described body 3 was installed:

1, with the wedging position aligned fit rail 11 of described body 3.

2, pull described eccentric handle 8 with palm, described eccentric handle 8 is axially rotated along described straight pin 6.When rotating, the axle center of described eccentric handle 8 is strengthened to the distance between the described briquetting 4, thereby pushes described briquetting 4 and described briquetting 4 is moved forward on described pull bar 5, and clamps described cooperation rail 11 gradually.

3, when described eccentric handle 8 turns to several angle, described locating stud 7 is corresponding with the spindle nose groove location of described pull bar 5, described locating stud 7 is because of the elastic force effect of described stage clip 10, be pushed in the spindle nose groove of described pull bar 5, tighten rapidly, be complete self-locking action, device enters safe locking state.

When needs were removed locking, step was as follows:

1, with the described piece 9 of stirring of hand propulsion, the upper end of described locating stud 7 is recessed in the spindle nose groove of described pull bar 5.

2, rotate described eccentric handle 8 again, make described briquetting 4 move and leave described cooperation rail 11 backward.

3, when described briquetting 4 leaves described cooperation rail 11 fully, directly take off described body and get final product.

The utility model can be widely used in the field that accidental release was locked, frees repeatedly, prevented to various needs fast.
