Abstract
The invention relates to a fastening bolt assembly with a spring, in particular to a fastening bolt assembly applied to hermetic connection of shell parts under the vibrating state, and belongs to the technical field of connectors. The fastening bolt assembly comprises a bolt sleeved with the spring. A limit bushing is arranged between the spring and the bolt. The outside of the lower end of the limit bushing is provided with a projecting outer limit spigot. A washer is supported at the upper end of the outer limit spigot. The lower end of a bolt head is provided with a limit block. The inner side of the upper end of the limit bushing is provided with a shrinking inner limit spigot. A rolled thread blocks the inner limit spigot so that the limit bushing cannot shed from the bolt. During assembly, the outer limit spigot of the limit bushing coordinates with a rubber gasket elongated hole, so that while the bolt is not unscrewed, the whole bolt spring structure and a cover are connected and never separate; compressing force is applied through a spring, the cover and a cylinder cover can be hermetically fitted reliably even when the cover deforms; the fastening bolt assembly has good stability.
Description
Technical field
The present invention relates to a kind of clamping bolt assembly with spring, for the sealed attachment of vibrational state lower shell body class part, belong 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, in assembly process, tight a bolt Compress Spring to realize 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, when dress folding bolt can occur separatedly with spring, to component, place and also make troubles.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thereby a kind of clamping bolt assembly with spring is provided, easy accessibility, little to pad damage, reduce and produce and maintenance cost, realize stable equilibrium sealing between cover cap and cylinder head simultaneously.
According to technological scheme provided by the invention, with the clamping bolt assembly of spring, comprise bolt, 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 a plurality of 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 present invention has the following advantages:
The present invention's outer spacing bayonet socket by limit casing when assembling coordinates with the close cylindrical void of rubber pad, 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; By spring, apply impacting force, 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 structural representation of the present invention.
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 present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Fig. 1 ~ 3, the present invention 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.
On bolt 1, pocketed springs 2, between spring 2 and bolt 1, are provided with limit casing 3.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, by limiting stopper 10, prevent that 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.
As further technological improvement, bolt 1 stage casing is established circumferencial direction and is provided with a plurality of indent projections 6.Indent projection 6 is blocked interior spacing bayonet socket 8 limit casing 3 cannot be come off from bolt 1.
The present invention adopts spring, limit casing, bolt and pad to coordinate and realizes combining of four part activities.Before installation, first by the present invention through cover cap hole, will outer spacing bayonet socket through the close cylindrical void of rubber pad, to the present invention is fixed on to close of rubber pad, go up, assembly parts of the present invention 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.
