Abstract
The utility model discloses a dust-proof cap for a cavity filter, which is characterized by comprising a cuboid casing made of EPE (expand aple poly ethylene), wherein the casing is provided with a notch used for placing a connector on the cavity filter; the diameter of the notch is equal to that of the connector on the cavity filter; and the depth of the notch is longer than that of the connector on the cavity filter. The dust-proof cap for the cavity filter is simple in structure, convenient in use and capable of avoiding damage between the connectors, completely avoiding defects of damage, impact and the like of outer threads of metal communication parts during production circulation, reducing waste of production cost, greatly improving production capacity and economic efficiency without increasing extra load as the EPE is light.
Description
Technical field
The utility model relates to a kind of cavity body filter, especially a kind of cavity body filter dust cap.
Background technology
Cavity body filter comprises cavity and is installed in connector on the cavity that during machining was produced, the external screw thread position of connector because of inappropriate to externally threaded protection, caused screw thread to damage, break, product rejection in producing circular flow.Dust cap on the existing connector is smaller, can not play the effect of protection connector, needs foam material in package to prevent damaging of connector usually again.
Summary of the invention
The utility model purpose is: provide a kind of simple in structure, the cavity body filter dust cap that can also prevent that connector from damaging easy to use.
The technical solution of the utility model is: a kind of cavity body filter dust cap, it is characterized in that, the housing that comprises the EPE material of rectangular shape, the recess that connector on the cavity body filter can be put into is arranged on the described housing, and the diameter of described recess equals the diameter of the connector on the described cavity body filter; The degree of depth of described recess is greater than the length of the connector on the described cavity body filter.
Further, the fixture that described housing can be fixed on the cavity body filter is arranged on the housing of described EPE material.
Further, described fixture is a rubber band.
The utility model has the advantages that: simple in structure, easy to use, can prevent the cavity body filter dust cap of damaging between the connector, the external screw thread position of can 100% avoiding metal communication part is producing bad defective such as cause that external screw thread is damaged, broken in the circular flow.Reduce the waste of production cost and improved production capacity and economic benefit greatly.The EPE material is light simultaneously, can not increase extra heavy burden.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a cavity body filter of the present utility model dust cap schematic diagram.
Embodiment
Embodiment: cavity body filter as shown in Figure 1, comprise the connector 1 on cavity 2 and the cavity, connector 1 has external screw thread.The cavity body filter dust cap comprises the housing 3 of the EPE material of rectangular shape, the recess 4 that connector on the cavity body filter can be put into is arranged on the housing 3, the diameter of recess 4 equals the diameter of the connector on the described cavity body filter, and the degree of depth of recess 4 is greater than the length of the connector on the described cavity body filter.In order to make dust cap better to be fixed on the cavity body filter, also be connected with rubber band on the dust cap.During use, dust cap is enclosed within on the connector of cavity body filter, re-uses rubber band and fix.Adopt cavity body filter dust cap of the present utility model, the external screw thread position of can 100% avoiding metal communication part is producing bad defective such as cause that external screw thread is damaged, broken in the circular flow.Reduce the waste of production cost and improved production capacity and economic benefit greatly.The EPE material is light simultaneously, can not increase extra heavy burden.
Above embodiment only is the utility model a kind of execution mode wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
