Abstract
The utility model relates to a fastening bolt assembly with a spring, and belongs to the technical field of connecting pieces. The fastening bolt assembly with the spring is used for sealing connection of shell type parts under vibration states. The fastening bolt assembly with the spring comprises a bolt, the bolt is sleeved with the spring, and a limiting sleeve is arranged between the spring and the bolt. A protruding outer limiting bayonet is formed in the outer side of the lower end of the limiting sleeve, and the upper end of the outer limiting bayonet supports a gasket. A limiting block is arranged at the lower end of a bolt head. An inner limiting bayonet shrinking inwards is formed in the inner side of the upper end of the limiting sleeve, and rolled threads block the inner limiting bayonet to enable the limiting sleeve not to fall off the bolt. When the fastening bolt assembly with the spring is assembled, the outer limiting bayonet of the limiting sleeve is matched with a rubber gasket sealing strip hole, the fact that a whole bolt spring structural member is connected together with a cover cap and cannot fall off is guaranteed under the condition that the bolt is not screwed down, through pressing force applied by the spring, reliable sealing between the cover cap and an air cylinder cover can be achieved even under the condition that the cover cap is deformed, and stability is good.
Description
Technical field
The utility model relates to a kind of clamping bolt assembly with spring, for the sealed attachment of vibrational state lower shell body class part, belongs to link technical field specifically.
Background technique
At present, the valve mechanism cover of motor is monolithic construction, and between itself and cylinder cap, sealing surface is larger, and cover structure poor rigidity easily deforms under vibration condition.Cover cap Main Function is mist of oil in canned motor crankcase, and sealing load is less demanding but want stable equilibrium.General sealed attachment method is between cover cap and cylinder head, to increase close of rubber pad, adopt bolt to coordinate and tighten with pad, this joining method cannot provide suitable bolt tightening moment, cross pine and easily cause gasket seal sternly not cause seepage, tension easily causes distortion and the damage seepage of close of rubber pad.Also there is the bolt of employing to coordinate spring to carry out resilient connection, the general bolt that adopts directly coordinates with spring, the Compress Spring that tights a bolt in assembly process is realized sealing, but spring and bolt directly suit can bring certain trouble to assembling, bolt press-fits will pass gasket and cover cap unthreaded hole, and centering is bad, is difficult for assembling, in the time of folding dress, bolt can separate with spring, places and also makes troubles to component.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of clamping bolt assembly with spring is provided, and easy accessibility is little to pad damage, reduces and produces and maintenance cost, realizes stable equilibrium sealing between cover cap and cylinder head simultaneously.
The technological scheme providing according to the utility model, comprises bolt with the clamping bolt assembly of spring, and bolt upper end is provided with bolt head, and bolt lower end is provided with rolled thread, it is characterized in that: pocketed springs on bolt, is provided with limit casing between spring and bolt.Limit casing lower end outside is provided with the outer spacing bayonet socket of protrusion, and outer spacing bayonet socket upper end support pad also limits pad and comes off from limit casing.Bolt head lower end is provided with limiting stopper.Inner side, limit casing upper end is provided with the interior spacing bayonet socket inside contracting, and rolled thread blocks interior spacing bayonet socket limit casing cannot be come off from bolt.
Further, limiting stopper is to be fixed on the end face of flange on bolt head or to be slidably mounted on the Upper gasket on bolt.
Further, bolt stage casing is established circumferencial direction and is provided with multiple indent projections, and indent projection is blocked interior spacing bayonet socket limit casing cannot be come off from bolt.
Compared with the prior art the utility model has the following advantages:
The utility model coordinates with the close cylindrical void of rubber pad by the outer spacing bayonet socket of limit casing in the time of assembling, guarantee under the condition not tighting a bolt, whole bolt spring structural member and cover cap are bonded together and can not come off, and easy-to-operat is increased work efficiency and has mistake proofing effect; Apply impacting force by spring, even in the situation that cover cap is out of shape, also can realize reliable sealing between cover cap and cylinder head, good stability; Easy accessibility is little to pad damage.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is bolt arrangement schematic diagram.
Fig. 3 is spacing sleeve structure schematic diagram.
Description of reference numerals: spacing bayonet socket, the outer spacing bayonet socket of 9-, 10-limiting stopper in 1-bolt, 2-spring, 3-limit casing, 4-pad, 5-bolt head, 6-indent projection, 7-rolled thread, 8-.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Fig. 1 ~ 3, the utility model mainly comprises bolt 1, and bolt 1 upper end is provided with bolt head 5, and bolt 1 lower end is provided with rolled thread 7.
Pocketed springs 2 on bolt 1, is provided with limit casing 3 between spring 2 and bolt 1.Limit casing 3 lower ends outsides are provided with the outer spacing bayonet socket 9 of protrusion, and outer spacing bayonet socket 9 upper end support pad 4 also limit pad 4 and come off from limit casing 3.Outer spacing bayonet socket 9 prevents that pad 4 from coming off, and pad 4 prevents that spring 2 from coming off.Bolt head 5 lower ends are provided with limiting stopper 10, prevent that by limiting stopper 10 spring 2 from coming off.Limiting stopper 10 is for to be fixed on the end face of flange on bolt head 5 or to be slidably mounted on the Upper gasket on bolt 1.
Limit casing 3 inner sides, upper end are provided with the interior spacing bayonet socket 8 inside contracting, and indent projection 6 is blocked interior spacing bayonet socket 8 limit casing 3 cannot be come off from bolt 1.
As further technological improvement, bolt 1 stage casing is established circumferencial direction and is provided with multiple indent projections 6.Indent projection 6 is blocked interior spacing bayonet socket 8 limit casing 3 cannot be come off from bolt 1.
The utility model adopts spring, limit casing, bolt and pad to coordinate and realizes combining of four part activities.Before installation, first by the utility model through cover cap hole, will outer spacing bayonet socket through the close cylindrical void of rubber pad, go up to the utility model is fixed on to close of rubber pad, assembly parts of the present utility model like this before assembling with cover cap and pad close and link together.Can easily realize the dismounting of cover cap, convenient for maintaining.In assembly process, by the effect of limit casing, guarantee that spring is compacted by certain compression height, realize pad impacting force appropriateness stable, reach reliable sealing.
