Description

A kind of stop screw component

Technical field

The utility model relates to a kind of screw assemblies, especially a kind of stop screw component.

Background technique

Screw is widely used in daily life as fastener, and the thin-walled housing in plant produced, panel is also required to spiral shell Nail is fixed, and common state's tender screw assemblies are not suitable for specific place and use, and carries out nonstandard customization according to field of employment demand, We have developed a kind of stop screw component thus, by compared with screw thread on short thread bar and panel screw and automatic impaction, prevent Vibration, will not loosen.

Utility model content

The utility model aim is to provide a kind of stop screw component for overcome the deficiencies in the prior art.

In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of stop screw component, feature exist In: including screw, spring and bracket, the bracket is hollow column structure, is successively arranged dentate body on the downside of the bracket And cone, the inside of the bracket are successively arranged hole one, hole two and hole three from top to bottom；One end of the spring and the hole One bottom surface abuts against, and the other end of the spring and the bottom surface of the socket cap of the screw abut against, the socket cap it is another One end is equipped with cross recess；The screw is successively arranged socket cap, cone bar, polished rod and threaded rod from top to bottom, the threaded rod Outer diameter is greater than the outer diameter of the polished rod, and the distance between the socket cap and the bracket are H, after stop screw component fastening, The distance of the bracket to the screw thread boom end is h, and the distance h≤5.97mm, the distance h are greater than the threaded rod The circumferential surface of reach, the dentate body is equipped with uniformly distributed tooth form, and the conical surface of the cone and the angle of horizontal plane are α, the angle α are 30 °~45 °.The cone bar of the screw is convenient for the positioning of spring, the hole two spiral shell to be processed convenient for threaded rod Nail is across the diameter in the hole two is less than the diameter in the hole one and the hole three.

Preferably, the distance H and the distance h are equal.

Preferably, the outer diameter of the socket cap is more than or equal to the outer diameter of the bracket, and the outer diameter of the bracket is greater than described The outer diameter of dentate body, the outer diameter of the dentate body are greater than the outer diameter of the cone.The top-down outer diameter of stop screw component It gradually becomes smaller, reduces the loading force for being applied to fixation surface when fastening.

Preferably, the height in the hole two is at least 0.7mm, and the diameter in the hole two is less than the major diameter of the threaded rod. The diameter in the hole two is greater than the outer diameter of the threaded rod blank of the screw.

Preferably, the distance L of the dentate body upper surface of the bracket to frame bottom is 0.77~0.93mm.It is convenient for With being fastened for thin-walled panel.

Preferably, the angle α is 32 °.

Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art

Stop screw component described in the utility model, including screw, spring and bracket, the internal stent are equipped with stepped hole Column structure, compressed by screw thread on the relatively short thread bar on screw and screwing for panel with automatic attaching, vibration proof, no It can loosen.

Detailed description of the invention

Attached drawing 1 is the original state figure of stop screw component described in the utility model；

Attached drawing 2 is the impaction state figure of stop screw component described in the utility model；

Attached drawing 3 is the cross-sectional view of bracket described in the utility model；

Specific embodiment

With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.

In attached drawing 1- attached drawing 3, a kind of stop screw component, including screw 10, spring 20 and bracket 30, the bracket 30 be Hollow column structure, the downside of the bracket 30 are successively arranged dentate body 31 and cone 32, and the inside of the bracket 30 is certainly It is upper and under be successively arranged hole 1, hole 2 36 and hole 3 37, the height in the hole 2 36 is at least 0.7mm, the hole two it is straight Diameter is less than the diameter in hole one and hole three；One end of the spring 20 and the bottom surface in the hole 1 abut against, the spring 20 The bottom surface of the other end and the socket cap 12 of the screw 10 abuts against, and the other end of the socket cap 12 is equipped with cross recess 11；Institute State screw 10 be successively arranged from top to bottom socket cap 12, cone bar 15, polished rod 16 and threaded rod 17, the major diameter of the threaded rod 17 it is big In the outer diameter of the polished rod 16, the diameter in the hole 2 36 is less than the major diameter of the threaded rod 17；The socket cap 12 and described The distance between bracket 30 is H, and after stop screw component fastening, the distance of the bracket 30 to 17 end of threaded rod is h, The distance H and the distance h are equal, the distance h≤5.97mm, and the screw thread that the distance h is greater than the threaded rod 17 is long Degree；The circumferential surface of the dentate body 31 is equipped with uniformly distributed tooth form, and the conical surface of the cone 32 and the angle of horizontal plane are α, The angle α is 30 °~45 °, preferably 32 °.
