Description

A kind of painting canvas folder

Technical field

The utility model relates to a kind of clamping devices, and in particular to one kind is for clamping the painting canvas such as painting canvas, poster paper, music score Folder.

Background technique

Painting canvas clamping device generally includes fixed plate and gripper frame, and the side of gripper frame is fixed on fixed plate by spring On, clamping is played the role of by the elastic force of spring in the other side.Not to the utmost conjunction of the existing this kind of painting canvas clamping device due to structure Reason, elastic force is smaller, and clamping not strongly for painting canvas is solid, is easy to appear and loosens, using also not convenient enough.It is existing for firm grip Some clamping devices are improved by each associated components larger or by way of increasing holding area, this simple ruler Planar defect in the presence of very little improvement: first, occupied space is big when it is applied in advertisement cabinet, raw material is wasted, folder is opened simultaneously Tight operating difficulties；Second, due to being simple change in size, the no substantial variation of the construction of these clamping devices, structure Still unreasonable, such as since its corresponding gripper frame is difficult to accomplish to clamp wall surface fully-flattened while kissing completely with fixed plate plane It closes, in actual use, the clamping wall surface of gripper frame the big to be easier occur clamping not tight phenomenon instead, it is easier to painting canvas occurs Loosen problem；Especially when the corresponding site for clamping wall surface or painting canvas is stained with foul, protrusion etc., it is easier to painting canvas occur Clamp unstable unstable problem.In addition, existing also some clamping devices merely use to clamp robust Increasing the usage quantity of painting canvas folder, clamps stable, firm purpose to reach, this not only increases cost of manufacture and use cost, And trivial operations when using.

Movable increasing in view of business community, various exhibition display meetings, the interim propaganda activity of product etc. can all use To interim billboard, therefore, how for this billboard-like painting canvas design it is a kind of not only small and exquisite it is portable, occupy little space, but also clamping It is firm, pressed from both sides using painting canvas simple to operate, become urgent problem to be solved.

Summary of the invention

The purpose of the utility model is to provide it is a kind of not only small and exquisite it is portable, occupy little space, but also clamping it is firm, use operation letter Single convenient painting canvas folder.

In order to achieve the above objectives, the technical solution adopted in the utility model is:

A kind of painting canvas folder, including pedestal and gland,

The main body of the pedestal is a groove type component, is equipped with an elastic arm, institute on the outside of the cell wall of the groove type component The one end for stating elastic arm is connect with cell wall, and the other end is equipped with a pin shaft, and the elastic arm is inclined to set, and its pin shaft end court It is rolled to the notch far from groove type component oblique；A linking arm is also vertically equipped on the outside of the slot arm of the groove type component, it is described Linking arm and elastic arm are located at the same side of groove type component, and the linking arm is located most closely to the slot of the groove type component Mouth side, the inside of the groove type component form the clip slot for fixing the painting canvas folder；

The gland is equipped with arc-shaped card slot, and the two sides of the card slot on the gland have each extended over the first side arm and the Two side arms, first side arm and the second side arm constitute L-type structure, and the outer end of first side arm is free end, and described second The outer end inner vertical of side arm is extended with compressed part, and the compressed part and the lateral surface of second side arm junction are provided with arc Shape chamfering；

Card slot on the gland is rotationally connected with the pin shaft on pedestal, be equipped on the inside of the outer end of the linking arm with it is described The contact portion that compressed part is in contact, when the gland is in stitching state with pedestal, the compressed part and the contact portion are mutual It contradicts, for clamping painting canvas.

The further improved technical solution of above-mentioned technical proposal is as follows:

1, as priority scheme: the central location of the elastic arm is additionally provided with an inflection point, and the inflection point is located at remote Side from the linking arm.

2, as priority scheme: the pin shaft is spherical structure.

3, as priority scheme: the wavy laciniation of contact portion outer rim.

4, as priority scheme: the pedestal and gland are all made of aluminum alloy materials.

5, as priority scheme: the pedestal and gland are all integrally formed.

Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art

1. the utility model painting canvas folder not only it is small and exquisite it is portable, occupy little space, but also clamping it is firm, use side easy to operate Just, can be used for clamping painting canvas, poster paper, music score etc..

2. the design of the lateral surface arc angling of the compressed part of the utility model and the second side arm junction, the arc angling For a relatively large chamfering, it can both play the role of guiding；Make again painting canvas be clipped in it is rotating closed during, can It smoothly runs, reduces the generation of noise；The abrasion in operational process is reduced simultaneously, increases the service life of product；In addition, the arc The design of chamfering, which is not only able to maximumlly to simplify material, reduces cost, and does not interfere with the clamping degree of product.

3. the utility model is by increasing elastic arm with inflection point and the structure of elastic arm that is obliquely installed designs Toughness and elasticity can obtain better toughness and more preferably so that painting canvas is clipped in rotating closed and during clamping painting canvas Stress release, be not in the phenomenon that automatic rebounding causes painting canvas to fall off and after painting canvas is clamped.

4. the design of the wavy laciniation of the utility model contact portion outer rim, effectively increase gland and painting canvas with And the frictional force between painting canvas and pedestal, so that painting canvas is not easily to fall off after clamping.

5. painting canvas folder is fixed on other pendants, such as wall by the design of the utility model pedestal upper fastening groove conducive to when using Wall, bracket etc..
