Abstract
The present invention relates to a kind of oil pump maintenance lid sealing configuration, comprise body and seal ring; Lid realizes being connected with Self-locking screw and car body by Square Lock, in oil pump maintenance lid edge stamped recess, seals position realize effective sealing by sealer compression seal rubber ring and inspection and repair of carbody mouth; The technical program effectively can keep sealing, and by using metal material lid, improves acoustic isolation effect and lid intensity, avoids touching because of extruding or wiping causing lid to damage.
Description
Technical field
The invention belongs to automotive sealant accessory technical field, refer to a kind of oil pump maintenance lid sealing configuration especially.
Background technique
Due to oil product and process management and control problem, fuel oil pump assembly is the parts that easily break down in oil-fired system, and fuel oil pump assembly is arranged in fuel tank internal, and it checks or dismounting and change needs could realize after dismounting fuel tank assembly.For simplifying maintenance process, need formulate at lower body the access opening that given size is opened in position, and with the sealing of oil pump maintenance lid, to reach the object of convenient maintenance.Consider car load NVH requirement, the isolation performance of oil pump maintenance lid to sound more and more receives publicity, and especially in high pressure oil transfer pump working procedure, oil transfer pump noise, higher than conventional oil oil-pressing pump, requires harsher to soundproof effect.
Oil pump maintenance lid of the prior art adopts plastic material, and caulking gum material is ethylene propylene diene rubber, and rubber transversal is hangnail type structure, is connected with lid hole by protruding structure; Access hole cap assembly realizes being connected with inspection and repair of carbody hole by square button+Self-locking screw.
Because plastic materials itself is poor to sound wave isolation performance, inapplicable with the high pressure oil pump isolation of noise; Caulking gum is connected by protruding structure with lid, there is the shortcoming connecting and closely easily do not produce gap, thus affects soundproof effect; Working of plastics intensity, far below metalwork, exists and damages risk.Therefore, a kind of oil pump access hole sealing cover of new structure is needed.
Summary of the invention
Object of the present invention is exactly the defect existed for prior art, and develops a kind of oil pump access hole sealing cover of new structure.By using the oil pump maintenance lid body of metallic material, improve acoustic isolation effect and lid intensity; Sealing stability is improved by new caulking gum and lid Placement.
The present invention is achieved by the following technical solutions:
A kind of oil pump maintenance lid sealing configuration, comprises body and seal ring;
The edge of described body is evenly provided with at least three Self-locking screw pilot holes;
The surrounding of described body is evenly provided with at least three snap closes, seals the groove at position or projection matches with inspection and repair of carbody mouth; Described snap close and Self-locking screw pilot hole interval are arranged;
Be provided with a circle groove inside described Self-locking screw pilot hole and snap close, coordinate with seal ring;
The zone line of described body is provided with a counterbore, seals via hole coordinate with harness rubber.
Described seal ring, its cross section and body assemble to be held as plane, is arc shaped surface with body sealing end; The thickness of described seal ring is slightly larger than the degree of depth of groove.
The plane of described body and seal ring adopts sealer form of fitting to seal.
Described body zone line strikes out elliptical shape.
Described punching press counterbore is other is provided with assembling mark blind hole.
Described snap close, groove, counterbore and assembling mark blind hole are stamped to form.
Described body and snap close assemble position and wash a mouthful groove open.
Described body is square, rectangular, triangle, ellipse and other are polygonal.
Described snap close is square.
Described seal ring adopts EPDM rubber material.
Advantageous Effects of the present invention is:
Effective sealing is realized by compression seal rubber between maintenance lid and inspection and repair of carbody mouth; Pasted by groove+plane colloid seal form between sealing rubber ring and maintenance lid, effectively can keep sealing; By using metal material lid, improve acoustic isolation effect and lid intensity, avoiding touching because of extruding or wiping causing lid to damage.

Embodiment
Describe technological scheme of the present invention below by way of specific embodiment, following instance is only exemplary, only can be used for explaining and technological scheme of the present invention being described, and can not be interpreted as being the restriction to technical solution of the present invention.
The present invention be directed to the defect that prior art exists, propose effective improved procedure.Particularly, as shown in Figures 1 to 8, oil pump access hole sealing cover of the present invention, comprises body 1 and seal ring 2.
Body is metal material, to improve acoustic isolation effect, improves lid intensity simultaneously, avoids touching because of extruding or wiping causing lid to damage.Body is set to square, and four angles place of body is respectively arranged with a Self-locking screw pilot hole 3, is connected with sealing position, inspection and repair of carbody hole by Self-locking screw; Four edges of square body are respectively arranged with a Square Lock 4, and snap close is stamped to form, and the groove 5 sealing position with inspection and repair of carbody mouth matches; Assemble position at body and Square Lock to wash mouthful groove 8 open and carry out structural strengthening; Snap close 4 and Self-locking screw pilot hole 3 interval are arranged, to increase sealing soundness.
Inside Self-locking screw pilot hole and snap close, groove 5 is enclosed in punching press one, coordinates with seal ring; Described seal ring, adopts EPDM rubber material; Its cross section and body assemble to be held as plane, is arc shaped surface with body sealing end; The thickness of seal ring slightly larger than the degree of depth of groove, to seal better when compressing.For increasing the stickiness of seal ring and body, between the plane and body recess of seal ring, sealer form of fitting is adopted to seal.
The zone line of body strikes out elliptical shape stiffening rib 9 to gain in strength; At the stiffening rib region punching press counterbore 6 of elliptical shape, provide harness rubber to seal via hole, be beneficial to wire harness and pass through, and in this region punching press with assembling the blind hole 7 of mark to instruct assembling.
In other embodiment of the application, described body also can be arranged to rectangular, triangle, ellipse and other are polygonal.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalency thereof.
