Detailed Description

The following detailed description of the embodiments of the present invention, such as the shapes and structures of the components, the mutual positions and connection relations among the components, the functions and operation principles of the components, will be made by referring to the accompanying drawings and the description of the embodiments:

as shown in the attached figure 1, the invention relates to a nut protection blocking cap structure for an automobile pipeline, which comprises a nut 1 and a blocking cap 2, wherein one end of the nut 1 is provided with a threaded hole 3, an internal threaded part 4 is arranged in the threaded hole 3, the blocking cap 2 comprises an outer protection ring 5 and an inner protection column 6, the diameter of the outer protection ring 5 of the blocking cap 2 is set to be larger than the outer diameter of the nut 1, and the diameter of the inner protection column 6 is set to be smaller than the outer diameter of the threaded hole 3 of the nut 1. The above structure is directed to a structure of a nut including a threaded hole in which an internal thread portion is provided. In order to protect the nut from collision and damage in transportation, the blocking cap is sleeved. And the plug cap with a special structure is designed corresponding to the structure of the nut. When the blocking cap is sleeved on the nut, the outer protective ring 5 of the blocking cap 2 is sleeved on the nut 1, the inner protective column 6 of the blocking cap 2 extends into the threaded hole 3, and a gap 8 exists between the side surface of the inner protective column 6 and the inner threaded part 4. Like this, on the one hand, the outside of stifled cap through outer guard circle protection nut, on the other hand, the interior guard post of stifled cap does not contact with the screw thread portion of nut, avoids interior stifled cap and the screw thread frictional contact of stopper structure, and stifled cap demolishs also fairly conveniently. The nut protection blocking cap structure for the automobile pipeline is simple in structure, effectively protects the nut, avoids collision in the nut transportation process, reliably protects the nut, ensures that the threaded part of the nut cannot be damaged, and meets use requirements.

The blocking cap 2 comprises a blocking cap bottom 7, an outer protection ring 5 is arranged on the outer ring of the blocking cap bottom 7, and an inner protection column 6 which is vertically arranged is arranged in the center of the blocking cap bottom 7. The blocking cap 2 is arranged to be capable of being sleeved on the nut 1. The structure of the blocking cap is limited, so that the axis of the outer protective ring is coincident with the axis of the inner protective column. Thus, when the plugging cap is sleeved on the nut, the outer protection ring is clamped outside the nut, and the inner protection column extends into the threaded hole. On the one hand, realize the reliable chucking of stifled cap and nut, on the other hand, can not contact the internal thread portion of damage.

When the plugging cap 2 is sleeved on the nut 1, the outer protection ring 5 of the plugging cap 2 is set to be a structure capable of being sleeved on the nut 1, and the inner protection column 6 of the plugging cap 2 is set to be a structure capable of extending into the threaded hole 3. When the plugging cap 2 is sleeved on the nut 1, the end part of one end of the nut 1, which is provided with the threaded hole 3, is set to be a structure which can be attached to the bottom 7 of the plugging cap. When the inner protection column 6 of the plugging cap 2 extends into the threaded hole 3, a gap 8 is formed between the side surface of the inner protection column 6 and the internal threaded part 4. Above-mentioned structure realizes convenient and reliable suit and the separation of stifled cap and nut, effectively protects the nut, and the existence of clearance portion avoids contacting internal thread portion.

The plugging cap 2 is of a structure made of plastic materials. Above-mentioned structure, stifled cap are plastic material, and is with low costs, takes the flexibility moreover, even if with the contact of nut can, can not harm the nut yet.

The diameter size of the lower part of the outer protection ring 5 of the plugging cap 2 is set to be larger than the diameter size of the upper part of the outer protection ring 5, and the diameter size of the lower part of the outer protection ring 5 of the plugging cap 2 is set to be equal to the diameter size of the nut 1. The upper part of the outer protection ring 5 of the plugging cap 2 is provided with a gap part. Above-mentioned structure, on the one hand for the nut can get into stifled cap through the outer guard circle upper portion of breach portion, and on the other hand, the nut gets into the back outer guard circle lower part spacing, avoids droing easily.

The nut protective plugging cap structure for the automobile pipeline, provided by the invention, aims at the structure of the nut and comprises a threaded hole, and an internal threaded part is arranged in the threaded hole. In order to protect the nut from collision and damage in transportation, the blocking cap is sleeved. And the plug cap with a special structure is designed corresponding to the structure of the nut. When the blocking cap is sleeved on the nut, the outer protection ring of the blocking cap is sleeved on the nut, the inner protection column of the blocking cap extends into the threaded hole, and a gap exists between the side surface of the inner protection column and the inner threaded part. Like this, on the one hand, the outside of stifled cap through outer guard circle protection nut, on the other hand, the interior guard post of stifled cap does not contact with the screw thread portion of nut, avoids interior stifled cap and the screw thread frictional contact of stopper structure, and stifled cap demolishs also fairly conveniently. The nut protection blocking cap structure for the automobile pipeline is simple in structure and low in cost, effectively protects the nut, avoids collision in the nut transportation process, reliably protects the nut, ensures that the threaded part of the nut cannot be damaged, and meets the use requirement.
