Abstract

The utility model discloses a dust-bonding rotary drum with a lock catch, which comprises a rotary drum (10), a rolling shaft (3) and a handle (4), wherein the rolling shaft (3) is sheathed and connected with the handle (4) from one end to the other end, and a holding part of the handle (4) is arranged at one end side of the rolling shaft (3). As a lock catch bracket (5) is arranged on the rolling shaft (3), and due to a cam (6) on the rolling shaft (3), the rotary drum (10) is locked with the rolling shaft (3) due to the principle of a cam during rotating, and the edge of the lock catch can be higher than the surface of the rolling shaft of the rotary drum or lower than the surface of the rolling shaft of the rotary drum. By adopting the dust-bonding rotary drum, the defect that the common rotary drum can not fix a rotary drum product on the rolling shaft is solved when the common rotary drum is in use, and the practical applicability and the convenience of the dust-bonding rotary drum are improved, so that the dust-binding rotary drum can be widely applied to various manual dust-bonding products.

Description

A kind of Dust adhering roller with snap close

Technical field

The utility model relates to uses a kind of cleaning supplies, refers to a kind of Dust adhering roller with snap close that makes things convenient for the snap close cylinder in roller bearing especially.

Background technology

Existing Dust adhering roller, when resting barrel and roller bearing, the frictional force between the dependence realizes.And relying on this mode, meeting is because of the reason of tolerance, and extruding and the wearing and tearing of repeatedly using the back to shine, and frictional force is reduced, and causes cylinder to skid easily in use, influences use, makes troubles.

The utility model content

In order to overcome the defective of skidding easily, the purpose of this utility model is, utilizes the cam principle, relies on the snap close support to fix cylinder, solves the defective that common cylinder skids easily.

In order to overcome the above problems, the scheme that the utility model is taked is: a kind of Dust adhering roller with snap close, has cylinder, roller bearing and handle, this roller bearing socket handle that passes through, the holding area of this handle is one distolateral in this roller bearing, this roller bearing is articulated in this handle end, this drum sleeve is connected to outside this roller bearing, wherein: the other end that this roller bearing does not articulate handle is provided with a snap close support, this snap close support is provided with the edge that supports that radius and arc all equal this roller bearing outer rim, this roller bearing is provided with an eccentric cam at this other end, this roller bearing axle center is departed from this eccentric cam axle center, promptly departs from the handle end axle center, and this snap close support is provided with pivoted hole and is sheathed on this eccentric cam, this snap close support can be that the axle center is rotated with this eccentric cam, thereby to support relative pintle hook lock roller bearing of edge and cylinder.

Described eccentric cam profile the best is circular.

Described roller bearing is provided with to segmental arc the edge that supports that should the snap close support, and supports edge and support segmental arc to cooperate that to keep out this cylinder inboard and position pintle hook lock.

At two ends, handle socket part, a U-shaped trip is stuck in top, handle socket part to the Dust adhering roller that snap close arranged of the present utility model, and packing ring, cylinder roller bearing, handle socket part and snap close support are fixed by two gasket sleeves.

The beneficial effects of the utility model are: utilize the cam principle, the snap close edge can be higher than roller surface, or is lower than roller surface.The utility model has solved the drawback of the cylinder product of common cylinder in use can't fixed roller, has improved Dust adhering roller practicality and convenience, but in extensive use and all kinds of manual binding dust product.

The specific embodiment

Conjunction with figs. is introduced the utility model in detail

With reference to the accompanying

drawings

1,2,3,4, a kind of Dust adhering roller with snap close, have cylinder 10, roller bearing 3 and handle 4, this roller bearing 3 socket handle 4 that passes through, the holding area of this handle 4 is one distolateral in this roller bearing 3, and this roller bearing 3 is articulated in this handle 4 ends, this cylinder 10 is socketed on outside this roller bearing 3, wherein:

The other end that this roller bearing 3 does not articulate handle 4 is provided with a snap close support 5, what this snap close support 5 was provided with that radius and arc all equal this roller bearing outer rim 3 supports edge 51, this roller bearing 3 is provided with an eccentric cam 6 at this other end, this this roller bearing axle center of eccentric cam 6 axis deviations, promptly depart from axle center, handle 4 end, this snap close support 5 is provided with pivoted hole and is sheathed on this eccentric cam 6, and this snap close support 5 can be that the axle center is rotated with this eccentric cam 6, thereby to support relative pintle hook lock roller bearing 3 of edge and cylinder 10.With this, when this Dust adhering roller of normal use, the edge 51 that supports of snap close support 5 turns to a side away from axle center, handle 4 end, at this moment, because, snap close support 5 integral body deflect away from this roller bearing 3, support edge 51 and also protrude from roller bearing 3, can be butted on this cylinder 10 inboards, and the edge 51 that supports that 3 pairs of this roller bearings should snap close support 5 is provided with to segmental arc 31, support preferably semi arch of segmental arc 31, preferably from the nearest axis client of eccentric cam 6 to axis client farthest, support edge 51 like this and support segmental arc 31 and cooperate that to keep out this cylinder 10 inboard and position pintle hook lock, and in click positions, support edge 51 eccentric cam 6 farthest axis client keep out in supporting segmental arc 31, in that do not have under the situation of external force not can self-return, will go to eccentric cam 6 nearest axis clients to edge 51 after the unlatching, at this moment, support edge 51 and be recovered in the roller bearing outer rim, cylinder can take off replacing.

It is circular that these eccentric cam 6 profiles are preferably, otherwise can't normally pivot, and corresponding its pivoted hole of this snap close support 5 also preferably also corresponds to circle, also can implement with other square hole or elliptical aperture certainly.

Two gasket sleeves 2 are at two ends, handle 4 socket part, a U-shaped trip 1 is stuck in top, handle 4 socket part, packing ring 2, cylinder roller bearing 3, handle 4 socket parts and snap close support 5 is fixing, roller bearing 3 can be rotated freely on handle 4, wherein handle 4 also passes snap close support 5, and U-shaped trip 1 and gasket sleeve 2 are assembled into one whole cylinder then.
