Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of Dustproof lid.
Background technology
Various types of water pumps are used to aspirate water, and water inlet and delivery port are set on the housing of water pump, for
The disengaging of water.After water pump dispatches from the factory, user's use will not be delivered immediately under normal circumstances, water pump is general in circulation or sales section
Be directly exposed to the external world, in these links, to prevent the invasion and attack of extraneous dust, generally require water pump water inlet or
Dust cap is set in delivery port.The structure of existing dust cap is mainly columnar body, and body has been internally formed cylinder
Cavity, directly body is tucked into the water inlet or delivery port of water pump, to reach the effect dust-proof to water pump.This structure
Dust cap easily can be tucked into the relevant position of water pump, but, it is necessary to dust cap during water pump use
Take out, and the dust cap of this structure is needed by means of instrument when taking out, it is generally the case that the dust cap is in the mistake being removed
Easily it is damaged in journey and influences whether use next time of dust cap.
To solve the problems, such as that it is above-mentioned that existing dust cap is present, Chinese patent discloses a kind of water pump dust cap [Granted publication
Number CN 203584788U], including shaft section is in the body of Qian shape, and plate, the both ends of plate and body are provided with body
Inner peripheral surface be connected as a single entity, body interior is separated into equal-sized two cavitys by plate.When taking out dust cap, finger
It is inserted respectively into two cavitys, clutches plate, you can dust cap is extracted from opening position is filled in, it is not necessary to by means of instrument
Dust cap is pried open.
But still there is problems with above-mentioned water pump dust cap：1st, by the way of drawing by body from filling in opening position
Extract, the power that hand is acted in connection sheet is axially extending along body, when body clamping is tighter, it is necessary to which larger power could be by it
Extract；2nd, body is by the madial wall CONTACT WITH FRICTION of raised line and water inlet or delivery port, when by impact axially outward,
Body easily comes off, and after using repeatedly, raised line abrasion, becomes big with the gap of water inlet or delivery port, subsequently reuse
When be easy to come off；3rd, it is provided with internal thread in the water inlet of some water pumps and delivery port, it is clear that the contact surface of raised line and internal thread
Small, body easily comes off, and dust-proof effect is poor.
The content of the invention
The purpose of this utility model is above mentioned problem be present for existing technology, it is proposed that a kind of connective stability is good
Dustproof lid.
The purpose of this utility model can be realized by following technical proposal：
This Dustproof lid, including rounded capping, the side of the capping, which is provided with, to be used to capping being detachably secured to
Attachment structure at pump intake, it is characterised in that the middle part of the capping is to the recessed formation in side provided with attachment structure
Cavity, the bottom of the cavity are fixed with the driving piece radially extended along capping, described driving piece away from attachment structure one
End is provided with mark formed with display surface, described display surface.
In above-mentioned Dustproof lid, described attachment structure includes the tubular connecting portion located at capping side, described
Connecting portion be coaxially disposed with capping, have on the outer wall of the connecting portion set with the screw-internal thread fit of pump intake it is outer
Screw thread, it is additionally provided with described connecting portion and allows bit architecture.
In above-mentioned Dustproof lid, the external diameter of connecting portion is less than the external diameter of capping.
In above-mentioned Dustproof lid, described allows bit architecture to include several uniformly edge connections on connecting portion
Coupling part is cut into several independent elastic valves by the axially extending fluting in portion, several flutings, and elastic valve is away from capping
One end is provided with spigot surface.
In above-mentioned Dustproof lid, described fluting is 2-6.
In above-mentioned Dustproof lid, described fluting is 2.
In above-mentioned Dustproof lid, described fluting is 3.
In above-mentioned Dustproof lid, described fluting is 4.
Capping, connecting portion and driving piece integrated injection molding in this dust cap, when in use, can hold driving
Piece, drive capping and connecting portion to move together, connecting portion is inserted into the water inlet of water pump, because some distending valves have one
Fixed elasticity, that connecting portion can also be inserted into water feeding of water pump is intraoral without being rotated, and after fully-inserted, elastic valve resets, and makes
External screw thread and the screw-internal thread fit in water inlet, prevent from coming off.After connecting, capping effectively can prevent dust from entering water inlet
It is interior.This dust cap is dust-proof except that can be carried out to the water inlet of water pump, can be also used for the dust-proof of pump outlet, the scope of application
Extensively.This dust cap, dust-proof effect of playing can be applied at the intake-outlet of water pump, but be not limited to the use of water pump, can be with
It is applied widely using other similar to pipe joint of water pump intake-outlet etc..
Compared with prior art, this Dustproof lid has advantages below：
1st, due to setting the external screw thread coordinated with pump intake screw thread, do not influenceed after connecting by axial force, be not easy to take off
Fall, ensure that the stability of dust cap；Connecting portion can be also connected to water feeding of water pump without rotary closure intraoral when the 2nd, connecting, can
Forward condition can be in by ensureing the mark on the display surface, convenient reading, equally can be by the information of some water pumps, dust cap
Model etc. is recorded in capping, ensures that the data of record are in forward condition all the time；3rd, drive piece outer end substantially with capping
Performance is concordant, can slightly protruding, reduce it and collided with external object, so as to improve the stability of dust cap.
