The device comprises a rolling shaft, wherein a plurality of elastic pieces are fixed to the circumferential surface of the rolling shaft, at least two cam clamping plates are arranged in a pivoted mode, a rotatable annular clamping hoop is arranged at the left end of the rolling shaft in a sleeved mode, a rotatable annular clamping hoop is arranged at the right end of the rolling shaft in a sleeved mode, and the rotatable annular clamping hoops are coaxially arranged; all the elastic pieces and the cam clamping plates are respectively arranged in the axial direction of the rolling shaft in sequence at intervals, and each cam clamping plate can pivot to be attached to at least one elastic piece; the left rotatable annular clamping hoop and the right rotatable annular clamping hoop are respectively provided with a bayonet, the end of the first left cam clamping plate and the end of the first right cam clamping plate stretch into the bayonet of the left clamping hoop and the bayonet of the right clamping hoop respectively, and when the first left cam clamping plate and the first right cam clamping plate pivot to be attached to the elastic pieces, the left clamping hoop and the right clamping hoop can rotate to clamp the two cam clamping plates respectively. The canvas fast-rolling-and-hanging device is suitable for fast and firmly hanging the canvas.

Description

Painting canvas is rolled up hang device fast

Technical field

The utility model relates to hanger technology, particularly relates to the technology that a kind of painting canvas is rolled up hang device fast.

Background technology

Spool is for hanging the conventional hanger of painting canvas, and the mode of viscose product the fixes painting canvas such as present spool structure is all fairly simple, and picture page all cements on spool by viscose products such as adhesive tapes, this employing adhesive tape has following defect:

1) speed of replacing painting canvas is very slow, and operating efficiency is low;

2) repeatedly change after painting canvas or long-term use, on spool, can be stained with viscose glue dirt, be difficult to clean, affect the firmness of follow-up connection, the fixedly reliability of painting canvas is poor.

Utility model content

For the defect existing in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of easy and simple to handle, and the painting canvas painting canvas that fixedly reliability is high is rolled up hang device fast.

In order to solve the problems of the technologies described above, a kind of painting canvas provided by the utility model is rolled up hang device fast, comprise spool, it is characterized in that: the side face of described spool is fixed with polylith and has flexible shell fragment, and being pivoted with at least two cam cleat, each coaxial sleeve of two ends, left and right of spool is equipped with an annular snap lock ring that can rotate;

Each shell fragment along spool axially successively interval lay, and be arranged in straight line;

Each cam cleat along spool axially successively interval lay, and be arranged in straight line, each cam cleat all can be switched to and at least one shell fragment laminating;

Left clamping hoop has open bayonet socket to the right, and the left end of first cam cleat stretches in the bayonet socket of left clamping hoop from left to right, and first cam cleat is switched to while fitting with shell fragment from left to right, and left clamping hoop can turn to its inner ring and prop up first cam cleat from left to right;

Right clamping hoop has open bayonet socket left, and the right-hand member of first cam cleat stretches in the bayonet socket of right clamping hoop from right to left, and first cam cleat is switched to while fitting with shell fragment from right to left, and right clamping hoop can turn to its inner ring and prop up first cam cleat from right to left.

Further, the two ends, left and right of described spool are respectively fixed with a stand connection.

The painting canvas that the utility model provides is rolled up hang device fast, that utilizes cam cleat and shell fragment coordinates to clamp painting canvas, and utilize clamping hoop to carry out lock cam clamping plate, and make the painting canvas can firm being fixed on spool, have that easy and simple to handle, upper picture speed is fast, the fixing high feature of reliability.

The specific embodiment

Below in conjunction with accompanying drawing explanation, embodiment of the present utility model is described in further detail, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof, all should list protection domain of the present utility model in.

As Figure 1-4, a kind of painting canvas that the utility model embodiment provides is rolled up hang device fast, comprise spool 1, it is characterized in that: the side face of described spool 1 is fixed with polylith and has flexible shell fragment 4, and being pivoted with at least two cam cleat 3, each coaxial sleeve of two ends, left and right of spool 1 is equipped with an annular snap lock ring 2 that can rotate;

Each shell fragment 4 along spool axially successively interval lay, and be arranged in straight line;

Each cam cleat 3 along spool axially successively interval lay, and be arranged in straight line, each cam cleat 3 all can be switched to and 4 laminatings of at least one shell fragment;

Left clamping hoop 2 has open bayonet socket to the right, the left end of first cam cleat 3 stretches in the bayonet socket of left clamping hoop from left to right, and when first cam cleat 3 is switched to shell fragment 4 laminating from left to right, left clamping hoop 2 can turn to its inner ring and prop up first cam cleat 3 from left to right;

Right clamping hoop 2 has open bayonet socket left, the right-hand member of first cam cleat 3 stretches in the bayonet socket of right clamping hoop from right to left, and when first cam cleat 3 is switched to shell fragment 4 laminating from right to left, right clamping hoop 2 can turn to its inner ring and prop up first cam cleat 3 from right to left.

In the utility model embodiment, the two ends, left and right of described spool 1 are respectively fixed with a stand connection 5.

The utility model embodiment is applicable to painting canvas and rolls up fast extension, and its occupation mode is as follows:

During initial use, device is in Fig. 1, released state shown in Fig. 2, now the upper end of painting canvas 7 be placed on spool and touch each shell fragment (referring to Fig. 5), then each cam cleat of pivotable, make each cam cleat prop up painting canvas, be that available each cam cleat is clamped painting canvas, and then rotate left and right clamping and bind round, make the inner ring of left and right clamping hoop cover respectively first cam cleat and from right to left first cam cleat from left to right, these two cam cleat can be locked (referring to Fig. 6), this timer is in the locking state shown in Fig. 6, under the clamping of each cam cleat and the elastic reaction of each shell fragment, painting canvas is by firm being fixed on spool,

In the time of need to taking off painting canvas 7, rotate left and right clamping hoop, make the bayonet socket of left and right clamping hoop aim at respectively first cam cleat and from right to left first cam cleat from left to right, these two cam cleat and left and right clamping hoop are thrown off, then each cam cleat of pivotable, make each cam cleat discharge the clamping to painting canvas, can take off painting canvas from spool.
