Description

A kind of cap

Technical field

The utility model belongs to automotive parts manufacturing technology, more particularly, to a kind of cap.

Background technique

Cap is used to block engine oil filler to prevent lubricating oil leakage, and traditional engine adds machine Oil port cover generally uses screw-type or card slot type, and not only manufacture is complicated, but also dismantles inconvenience, to the sealing effect of oil filler Difference.

Utility model content

The utility model for overcome the deficiencies in the prior art, provide a kind of structure it is simple, it is convenient for disassembly and assembly, to oil filler The cap of good airproof performance.

To achieve the goals above, the utility model uses following technical scheme：A kind of cap, can be with engine Oil filler matches, including lid ontology, and the lid ontology includes embedded division, and the lid ontology is connected by buckle structure sealing It is connected on the oil filler, the buckle structure includes the resettlement groove being set on the embedded division, is arranged in the resettlement groove Interior fastener and the card slot matched on the oil filler side wall with the fastener.The utility model structure letter It is single, pass through fastener and oil filler side by the way that the fastener matched with oil filler is arranged on embedded division convenient for manufacture Card slot on wall matches, and lid ontology can be sealedly connected on oil filler, and then realizes cap to adding machine oil The sealing function of mouth, due to snapping connection between cap and oil filler, therefore entire disassembly process is convenient, Yi Shi It applies.

Further, the embedded division is equipped with fixing piece, and the resettlement groove is set on the fixing piece.

Further, the fastener is a spring steel plate, and the card slot side wall is equipped with to match with the spring steel plate The oblique helicoid of conjunction；When assembly, embedded division only need to be pressed into oil filler, lid ontology is then rotated, so that spring steel plate card When entering in card slot, since the side wall of card slot is oblique helicoid setting, the rotation with lid, the both ends of spring steel plate along Oblique helicoid moves down, so that a shape to raise upward is presented in entire spring steel plate, since spring steel plate exists back The trend of multiple original state, so spring steel plate can apply a downward power to lid, so that lid energy tight closure exists On oil filler, and while dismantling, need to only rotate lid, so that spring steel plate is exited from card slot, so that it may easily by lid from adding It is taken out in machine oil mouth, entire disassembly process is simple and convenient.

Further, the spring steel plate cross section is arcuate structure setting；When spring steel plate enters card slot by rotary squeezing When middle, spring steel plate is under the squeezing action of card slot side wall and is squeezed into planar, the similarly reply of spring steel plate presence at this time To the trend of original arcuate structure, so spring steel plate can apply a downward extruding force to lid, so that lid can be more Closely block on oil filler.

Further, the embedded division is equipped with sealing element；By the setting of sealing element, when embedded division is in spring steel plate When in the lower insertion oil filler of effect, sealing element by squeezed tight between lid and oil filler side wall so that lid There is good sealing function to oil filler.

Further, the embedded division is equipped with dust-proof cushion；The setting of dust-proof cushion can prevent the substances such as dust enter plus In machine oil mouth.

Further, the lid top surface is equipped with hand and twists portion；Hand twists the setting in portion convenient for rotation, taking and placing lid.

In conclusion the utility model structure is simple, it, can be by lid originally by the cooperation of fastener and card slot convenient for manufacture Body is sealedly connected on oil filler, and whole dismounting process is simple and convenient, is easily implemented.

Specific embodiment

In order to make those skilled in the art better understand the utility model, below in conjunction with the utility model reality The attached drawing in example is applied, the technical solutions in the embodiments of the present invention are clearly and completely described.

As shown in Figure 1-3, a kind of cap, can match, including lid ontology 1 with engine oil filler 4, it is described Lid ontology includes the embedded division 3 in frustum cone structure, and oil filler side wall is equipped with boss 7, in embedded division insertion oil filler, Its lower surface can be inconsistent with boss upper surface, and the lid ontology 1 is sealedly attached to the oil filler by a buckle structure On, specifically, the buckle structure includes the resettlement groove 5 being set on the embedded division 3, the buckle being arranged in the resettlement groove Part 6 and the card slot 41 matched on the oil filler side wall with the fastener, specifically, 3 bottom surface of the embedded division It is equipped with fixing piece 31, is provided through horizontally disposed card slot on the fixing piece, the card slot both ends open is big-and-middle Between be open small, the fastener 6 is a spring steel plate, which is threaded through in resettlement groove 41 and both ends each extend over out and pacify It sets outside slot, the card slot, which is arranged on oil filler side wall, to be located at the position below boss, and number is set as two, two Card slot can be matched with the both ends of spring steel plate respectively, and 41 top and bottom sidewall of the card slot is the oblique helicoid tilted down, institute The boss for stating oil filler side wall is equipped with two notches being connected with the card slot, need to be by the two of spring steel plate when assembly Lid is pressed into oil filler after two notches of end alignment, lid is then rotated, so that the both ends of spring steel plate are respectively clamped into In card slot, since the top and bottom sidewall of card slot is oblique helicoid setting, so the both ends of spring steel plate can be along in rotary course Card slot is bent downwardly, so that spring steel plate bends to an arch to raise upward, is replied since spring steel plate exists always To the trend of original state, so the intermediate position of spring steel plate can apply a downward extruding force to lid, so that lid exists The lower surface of its embedded division and boss upper surface fit closely together under the action of this extruding force, and then reach closure and start The purpose of machine oil filler, and in disassembly, only need opposite direction to rotate lid, so that the both ends of spring steel plate are retracted into notch Place, so that it may easily take out lid, simple, convenient, the easy implementation of entire disassembly process.

Preferably, the spring steel plate cross section is the arc that middle part raises upward, when spring steel plate as lid rotates When being moved along the oblique helicoid of card slot side wall, since the gap between the top and bottom sidewall of card slot is smaller, the both ends quilt of spring steel plate Be squeezed into it is planar, likewise, spring steel plate can be to lid since spring steel plate is always there is the trend for returning back to original form Body generates a upward extruding force, so that the lower surface of embedded division is bonded closer, i.e. lid with the upper surface of boss It is more preferable to the plugging effect of oil filler.

In order to guarantee lid to the sealing effect of oil filler, sealing element 32 is equipped on the embedded division 3, specifically, The sealing element is the circular rubber pad being set on fixing piece, and when lid blocks on oil filler, rubber pad is tight It is close to be extruded between insertion lower surface and boss upper surface, and then excellent sealing effect is realized to oil filler.

Further, on the embedded division 3 be equipped with dust-proof cushion 33, when lid block on oil filler when, dust-proof cushion Setting effectively prevent dust and enter in oil filler.

And cap is dismounted for convenience, the hand on 1 top surface of lid equipped with an arcuate structure twists portion 11.

Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments. Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts The range of the utility model protection all should belong in every other embodiment.
