Description

A kind of helical teeth buckle

Technical field

The utility model relates to a kind of fastening parts of automobiles, especially relates to a kind of helical teeth buckle of being convenient to installation, firm and reliable connection.

Background technique

In auto assembly workshop, some body accessorieses are as fixed by snap on body in white in needs such as trim panel, rubber cushions, buckle easy accessibility, and application area is wider.During installation, first body accessories is placed on vehicle body, buckle passes on annex and is stuck on mounting hole, common buckle consists of cap and inserting column at present, inserting column is provided with latch, this class latch mean level arranges, as notification number is: a kind of Polyhedral blade-shaped buckle that the Chinese model utility of CN201818606U provides, comprise cap and insertosome, described cap and described insertosome are integrated to be made, the first surface of described cap is plane shape, described insertosome comprises a cross column body, one cone-shaped plug and some square lamellar bodies, the vertical connection of first surface of cross column body and described cap, square lamellar body is connected with four lateral vertical of cross column body, and be symmetrically distributed in four sides of cross column body, the bottom surface of cone-shaped plug is connected with the top of cross column body, second of described cap is circular arc, on described second, dermatoglyph is set.The buckle that this patent is mentioned, the latch on it is horizontally disposed with, and owing to there is no transitional surface, when buckle is installed, resistance will be very large, waste time and energy, and affect operating efficiency.Be subject in addition production technology horizontal constraints, may there is the phenomenon that part is covered in mounting hole, use this buckle even cannot install.

Model utility content

The utility model is mainly that existing installation is wasted time and energy for existing buckle, affects the problem of operating efficiency, a kind of simple structure is provided, simple and convenient, solid and reliable helical teeth buckle is installed.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of helical teeth buckle, comprise cap and inserting column, one end of inserting column is connected with cap, axial direction along inserting column on described inserting column is evenly laid with at least two tip surfaces, between adjacent tip surface, form latch district, in latch district, be equipped with some latches that tilt towards cap direction, the V-shaped arrangement of latch in adjacent latch district.The latch tilting has formed transitional surface, and stressed evenly level and smooth, when buckle is installed, resistance is less, time saving and energy saving.The V-shaped arrangement of latch in adjacent latch district, installs laborsavingly, and after installing, pretightening force is larger, reliable and stable, difficult drop-off.

As preferably, described tip surface has four, four tip surfaces are evenly arranged on the sidewall of inserting column, four tip surfaces form four latch districts that latch is set, the wherein V-shaped arrangement of latch in the Liang Ge latch district of arbitrary neighborhood, on the other side, the V-shaped arrangement of latch in two other latch district.Buckle is connected firmly stable after installing, difficult drop-off.

As preferably, the latch in adjacent Liang Ge latch district is interspersed.Buckle is connected firmly stable after installing.

As preferably, the latch in same latch district has nine, and nine latches are parallel to each other, and nine latches are all vertically connected on inserting column.Latch is connected with inserting column is vertical, and pretightening force is larger, and structural strength is higher.

As preferably, on described inserting column, one end relative with cap is installed with round table-like plug.Round table-like plug is convenient to inserting column and is inserted in mounting hole, the mounting hole especially covering for part, and effect is better.

As preferably, the integrative-structure that cap, inserting column and plug are molding and forming.Structural strength is high, and technique is simple.

As preferably, described inserting column is connected to the center portion of a side of cap, and another side of cap is the arc surface of middle part projection.Lifting surface area is large, and stressed steady equilibrium is convenient to install.

Therefore, the beneficial effects of the utility model are: latch tilts towards block direction, and V-shaped being interspersed of latch in adjacent latch district, and it is time saving and energy saving to install, and after installing, pretightening force is larger, and stable connection is reliable, difficult drop-off.

Accompanying drawing explanation

Accompanying drawing 1 is a kind of overall structure schematic diagram of the present utility model;

Accompanying drawing 2 is that A in accompanying drawing 1 is to schematic diagram.

Shown in figure: 1-cap, 2-inserting column, 3-tip surface ,4-latch district, 5-latch, 6-plug.

Embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment:

As Figure of description 1, shown in 2, a kind of helical teeth buckle, comprise cap 1 and inserting column 2, one end of inserting column 2 is connected to the center portion of a side of cap 1, another side of cap 1 is the arc surface of middle part projection, one end relative with cap 1 on inserting column 2 is installed with round table-like plug 6, cap 1, inserting column 2 and plug 6 are the integrative-structure of molding and forming, axial direction along inserting column 2 on inserting column 2 is evenly laid with four tip surfaces 3, between adjacent tip surface 3, form latch district 4, in latch district 4, be equipped with nine latches 5 that tilt towards cap 1 direction, nine latches 5 are parallel to each other, and nine latches 5 are all vertically connected on inserting column 2, four tip surfaces 3 are evenly arranged on the sidewall of inserting column 2, four tip surfaces 3 form four latch districts 4 that latch 5 is set, the wherein V-shaped arrangement of latch 5 in the Liang Ge latch district 4 of arbitrary neighborhood, on the other side, the V-shaped arrangement of latch 5 in two other latch district 4, latch 5 in adjacent Liang Ge latch district 4 is interspersed.

As shown in Figure of description 1, along B-B dotted line, can see, the latch in adjacent Liang Ge latch district is interspersed.

The structural feature of this buckle is as follows:

A) the latch design comparison of inserting column is special, with checkpost tooth, has and is straggly the arranging of " V " word, is consistent with the opposite latch arrangement mode of this plane of inserting column; Setting straggly before and after another side latch is, acutangulates and arranges with tip surface plane shape, and this plane is consistent with opposite latch arrangement mode.Above-mentioned latch design, has effectively reduced the strength demand that buckle inserts fixed hole, realizes the effect that insertion force is less than withdrawal force;

B) cap diameter is far longer than inserting column size, in conjunction with the design of latch, when giving it and exert pressure, lifting surface area is larger, makes inserting column part can insert very easily fixed hole, effectively alleviates the strength of employee while assembling and pays, be convenient to assembling, enhance productivity;

C) cylindric plug is designed in inserting column bottom, is buckled in good leading role while inserting fixed hole, effectively avoided that maskaperture mask phenomenon occurs cannot assembly problem generation.

D) cap and inserting column are " fourth " word and combine, and are conducive to buckle and are arranged in mounting hole;

E) tip surface links together latch, is fixed on inserting column, forms the branch form as " trees ", realizes the structure of whole buckle monolithic stability, is beneficial to the realization of buckle fixed effect.

Should be understood that this embodiment is only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
