Description
Technical Field
The utility model relates to an easel accessory technical field, concretely relates to metalwork is used in easel connection.
Background
The easel used outdoors needs to meet various requirements of being convenient to carry, use and the like. But portability and convenience in use are often contradictory. The easel convenient to carry is foldable generally, but the legs of the easel are difficult to fix in use if being convenient for storage. The applicant has patent numbers: the invention patent CN201520770166.1 discloses a triangle easel with a composite metal pull shell, which can further simplify the structure of the triangle easel without affecting the use effect, so that the triangle easel is more portable. For reaching the effect, this utility model relates to a triangle easel with shell is drawn to composite metal, including controlling supporting legs and back foot, control the supporting legs top and be equipped with the fixed orifices, it is fixed with the back foot to control the supporting legs through the fixed orifices, back foot top openly installs a combination metal and draws the shell, the combination metal draws the shell including being used for with controlling the link that the supporting legs is connected, fixes the vertical movable groove on the link and through the roof of bolt movable mounting in vertical movable groove. Since adopted technical scheme, the utility model discloses a combination metal draws the shell to replace the shell of drawing on that uses the wooden frame structure to give first place to among the prior art, has simplified the overall structure of easel, has alleviateed the weight and the manufacturing cost of easel, and more convenient to use person carries.
It is also disclosed in this patent that the easel falls down by placing the rear foot too wide via a chain (9) attached to the rear foot (2). In the actual use process, however, the chain is very cumbersome to carry, and the chain is twisted when a plurality of picture frames are put together. When in use, the chain is dragged on the ground and is easy to wear and oxidize.
Disclosure of Invention
In order to solve the problem, the utility model provides an easel is connected and is used metalwork for replace the chain. Can ensure that the easel foot can not be too big opened to cause the easel to collapse when the easel is used, and is more firm, durable and easy to carry.
For reaching the technical effect, the utility model discloses a technical scheme be: the utility model provides a metalwork is used in easel connection for connect the support body and the supporting legs of easel, constitute by banding first connection piece and second connection piece, first connection piece and second connection piece are connected with the support body and the supporting legs of easel respectively, and first connection piece and second connection piece front end are overlapped and are fixed through rotatory mounting, second connection piece side is equipped with and is equipped with the recess, first connection piece end be equipped with recess complex crotch.
Preferably, the first connecting sheet is a straight metal sheet, the second connecting sheet is a bent sheet, the rear end of the bent sheet is fixed to the supporting leg, the front end of the bent sheet and the first connecting sheet are kept on the same horizontal plane, and the front end and the rear end of the bent sheet are connected through a bending part.
Preferably, the edge of the groove is arc-shaped. Therefore, the hook can be smoothly clamped into the groove, and the whole process is not obstructed.
Preferably, the second tab terminates at a position that is lengthwise of the first tab 2/3. The force arm arrangement avoids overlarge stress on the connecting piece and can also sufficiently bear the pressure of a large drawing board.
Preferably, the length of the hook is more than 2 times of the width of the second connecting sheet. Such a construction is primarily intended to prevent the hook from falling out of the recess during use due to impact or other external influences.
Preferably, the first connecting piece and the second connecting piece are connected to each other by a movable bolt. Thus not becoming loose from multiple uses.
Preferably, the front ends of the first connecting sheet and the second connecting sheet are provided with lubricating gaskets at overlapped positions. The lubricating washer is used to reduce friction between the connecting tabs.
The utility model discloses a back is opened completely at the easel to such structure, through the cooperation of recess and crotch on first connection piece and the second connection piece, fixes the easel foot in a predetermined position, ensures that the easel of opening is stable, can not make the too big of easel foot moreover. Compared with the prior art, the whole metal connecting piece is smaller and more durable, and the easel can bear heavier drawing boards.
Drawings
Fig. 1 is a schematic view of the metal member for easel connection according to the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1, the utility model relates to a metalwork is used in easel connection for connect the support body and the supporting legs of easel, constitute by banding first connection piece 1 and second connection piece 2, first connection piece 1 and second connection piece 2 are connected with the support body and the supporting legs of easel respectively, and first connection piece 1 overlaps and fixes through rotatory mounting with 2 front ends of second connection piece, 2 sides of second connection piece are equipped with recess 4, 1 end of first connection piece be equipped with recess 4 complex crotch 3. The first connecting piece 1 is a straight metal sheet, the second connecting piece 2 is a bent piece, the rear end of the bent piece is fixed to the supporting leg, the front end of the bent piece and the first connecting piece 1 are kept on the same horizontal plane, and the front end and the rear end of the bent piece are connected through a bending part. In order to facilitate the hook 3 to slide into the groove 4 quickly and accurately, the edge of the groove 4 is arc-shaped.
In order to achieve the optimal moment arm position, the second connecting piece 2 is connected at the end thereof to the first connecting piece 12/3 at a length position. Simultaneously 3 times of length of crotch 3 for second connection piece 2 thereby avoid touch the easel when the drawing and lead to the crotch 3 to deviate from in the recess 4.
Usually the first connecting piece 1 and the second connecting piece 2 are connected to each other by means of a movable bolt 5. The movable bolt 5 has high strength and can not be easily damaged after long-term use. In order to reduce the abrasion, the front ends of the first connecting sheet 1 and the second connecting sheet 2 are provided with lubricating gaskets at overlapped positions.
When the easel is installed, the first connecting piece 1 is fixedly arranged at one end of the easel body, and the second connecting piece 2 is movably fixed on the supporting legs. The second connecting piece 2 is designed as a curved piece, so that the front end of the curved piece is kept on the same horizontal plane with the first connecting piece 1. This ensures that the hook 3 slides quickly and accurately into the recess 4 after the easel is opened.
The easel is used as a conventional folding easel and can be used only by being unfolded. The opened first connecting piece 1 and the second connecting piece 2 rotate relatively. Finally, after the hook 3 slides into the groove 4 quickly and accurately, the first connecting piece 1 and the second connecting piece 2 are fixed in position, so that the supporting legs are fixed, and the easel is in an open state. The easel in this position is most stable in use.
