Description

A kind of bolt block

Technical field

The utility model relates to mechanical field, is specifically related to a kind of bolt block.

Background technology

Bolt is widespread use on automobile, mainly play a part to be connected and fixed component, the reliability of bolt and weather resistance directly determine reliability and the weather resistance of whole car and each system parts, owing to the joint bolt on the component that have needs often dismounting, bolt and thread surface are easy to be subject to oxidation corrosion, have impact on the dismounting of bolt and reliability, for overcoming the above problems, some producers devise and a kind of are enclosed within the block outside bolt, bolt and nut are wrapped up, improve the life-span of bolt, and general capping structure more complicated, inefficiency during assembling, mounting or dismounting trouble, and cost of manufacture height.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of bolt block, and structure is simple, easy and simple to handle, be connected firmly, cost is low, easy accessibility.

For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of bolt block, comprise the lid cover being set on bolt, it is located at the block on lid cover top, described lid cover comprises sleeve, it is located at the gear ring inside sleeve bottom, ring is located at the edge of sleeve top outer, described block comprises the cap body of one end open, it is located at cap body opening end and coordinates spacing snap ring with edge, described edge comprises the first edge that two outer shaft cross sections become notch cuttype to arrange, 2nd edge, snap ring and the first edge card connect spacing, described lid cover and block all adopt plastics integrated injection molding.

The external diameter that the aperture of snap ring is more than or equal to the 2nd edge is less than the external diameter of the first edge, the aperture of snap ring becomes running fit with the external diameter of the 2nd edge or excessively coordinates, when bolt is protected by needs, lid is set to outside the screw rod needing protection, after fastening nut, by coordinating of gear ring and nut, lid cover can be made firmly to be fixed on outside screw rod, owing to lid cover and block all adopt plastics integrated injection molding, better tightness in protection process, non-corrosibility is better, longer service life, become with plastic working, production cost is lower, process convenient, pinching with hand just to make it that certain distortion occurs, after distortion, recovery effect is good, when nut is fixed after well, the edge end of lid cover only need to be pinched with hand, the minimum diameter distance of edge end just can be made to change, thus edge is overlapped fast and is set in block, when staff is not when applying pressure to lid cover, edge can restore fast, when block is pulled outward after on earth, block just can realize the protection to bolt with lid cover, the aperture of snap ring becomes running fit with the external diameter of the 2nd edge or excessively coordinates, can prevent moisture from entering block inner side as far as possible, thus improve the work-ing life of bolt, when block opened by needs, also only block need to be pushed away forward a segment distance and pinch flat lid cover simultaneously, just can take out fast, the process of protection can be reused, dismounting can complete instantaneously, structure is simple, easy and simple to handle, it is connected firmly, cost is low, easy accessibility.

As preferably, described cap body opening end outer ring is provided with the snap ring strengthening ring of an outer convex circular arc.

After cap body opening being carried out thickness increase by the snap ring strengthening ring of circular arc, substantially increasing the radial strength of cap body, be out of shape little after a long time use, connect more reliable, rear distortion amount affected by environment is little.

As preferably, the side uniform ring of described lid cover is provided with two the first vertical stiffening webs, and described first stiffening web adopts the arc-shaped structure of indent.

First can play the overall axial strength of lid cover, being out of shape little after a long time use, connect more reliable, rear distortion amount affected by environment is little, simultaneously, when the edge that puts of lid is placed in block due to, the first stiffening web adopts the arc-shaped structure of barrel entirety indent, after pinching sleeve with hand, sleeve wall can be out of shape fast along the depression place of the first stiffening web, thus making socket convenient, barrel can not be produced stress influence after reducing by the sleeve after distortion, and reduction effect is better.

As preferably, the outside uniform ring of described block is provided with four articles of the 2nd vertical stiffening webs, described 2nd stiffening web adopts the outer male structure of circular arc.

2nd stiffening web adopts the outer male structure of circular arc, after it is carried out reinforcement comprehensively by the four of peripheral hardware articles of the 2nd vertical stiffening webs by the outside of block, block effective its radial strength of guarantee and Axial distortion parameter when cost-saving can be made, make cap body be not easy distortion.

Embodiment

As depicted in figs. 1 and 2, a kind of bolt block, comprise the lid cover 1 being set on bolt, it is located at the block 2 on lid cover 1 top, described lid cover 1 comprises sleeve 8, it is located at the gear ring 9 of sleeve 8 bottom inside, ring is located at the edge 3 of sleeve 8 top outer, described block 2 comprises the cap body 10 of one end open, it is located at cap body 10 opening end and coordinates spacing snap ring 6 with edge 3, described edge 3 comprises the first edge 4 that two outer shaft cross sections become notch cuttype to arrange, 2nd edge 7, snap ring 6 and the first edge 4 card connect spacing, described lid cover 1 and block 2 all adopt plastics integrated injection molding, described cap body 10 opening end outer ring is provided with the snap ring strengthening ring 5 of an outer convex circular arc, the side uniform ring of described lid cover 1 is provided with two the first vertical stiffening webs 11, and described first stiffening web 11 adopts the arc-shaped structure of indent, the outside uniform ring of described block 2 is provided with four articles of the 2nd vertical stiffening webs 12, and described 2nd stiffening web 12 adopts the outer male structure of circular arc.

During real work,

When bolt is protected by needs, lid cover 1 is set to outside the screw rod needing protection, after fastening nut, by coordinating of gear ring 9 and nut, lid cover 1 can be made firmly to be fixed on outside screw rod, then sleeve 8 is pinched with hand, its circularity is made certain distortion to occur thus drive edge 3 to become oval, when the minimum diameter of the first edge 4 is less than the diameter of snap ring 6, it just can be made after allowing edge 3 one end be introduced into block 2 all to enter in block 2, thus make block 2 be set on lid cover 1, when staff is not when to lid cover 1 applying pressure, edge 3 can restore fast, when block 2 is pulled outward after on earth, the inwall of snap ring 6 coordinates with the outer wall of the 2nd edge 7, the interior side of snap ring 6 coordinates with the side of the first edge 4, block 2 just can realize the protection to bolt with lid cover 1, the aperture of snap ring 6 becomes running fit with the external diameter of the 2nd edge 7 or excessively coordinates, can prevent moisture from entering inside block 2 as far as possible, thus improve the work-ing life of bolt, when block 2 opened by needs, also only block 2 need to be pushed away forward a segment distance and pinch flat lid cover 1 simultaneously, just can take out fast, the process of protection can be reused, dismounting can complete instantaneously, structure is simple, easy and simple to handle, it is connected firmly, cost is low, easy accessibility, the axial depth of block 2 is greater than the diameter of the first edge 3, edge can be made to be out of shape after effectively convenient when going deep into.

Specific embodiment described herein is only to the utility model spirit explanation for example. Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by the utility model person of ordinary skill in the field, but can't deviate spirit of the present utility model or surmount the scope that appended claims defines.
