Description

Technical Field

[0001] This utility model relates to the field of easel technology, specifically to a folding easel for design purposes. Background Technology

[0002] An easel is a separate structure designed by artists to support their canvas while painting.

[0003] Modern easels are made of wood or metal and typically have legs and a back support on the upper side of the legs. When in use, the legs are extended and the drawing board is placed on them.

[0004] Because the easel is made of legs, it is quite tall. Although many easels are foldable, they usually fold by closing the legs together, which shrinks the easel, but the overall height of the easel usually remains the same. This makes it inconvenient to carry after painting, especially when painting outdoors. Utility Model Content

[0005] The purpose of this invention is to provide a folding easel for use in order to solve the problem mentioned in the background art that the current easels are usually still quite tall after being folded, making them inconvenient to carry.

[0007] Back panel, top panel, bottom panel, and two side support legs;

[0008] The top plate and bottom plate are respectively connected to the upper and lower ends of the back plate. The two side support legs are located on both sides of the back plate. The upper end and upper middle side between the two side support legs are respectively connected to a rotating shaft and a snap-fit ​​post. The middle and lower sides of the back of the back plate are respectively connected to a bearing seat and an open snap-fit ​​frame. The rotating shaft is rotatably inserted into the bearing seat. The snap-fit ​​post and the open snap-fit ​​frame are in corresponding positions and are sized to match.

[0009] Preferably, a sliding groove is provided in the middle of the upper surface of the back plate, the sliding groove extends along the back plate to the lower part of the back plate, and a telescopic mechanism that is slidably connected to the sliding groove is connected to the bottom of the top plate.

[0010] Preferably, the telescopic mechanism includes a cover plate connected to the upper side of the sliding groove by screws, a through hole in the middle of the cover plate, a movable rod connected to the middle of the top plate, the movable rod moving through the through hole, a limit ring connected to the bottom end of the movable rod, and a spring supporting the limit ring and the cover plate.

[0011] Preferably, the back plate and the bottom plate are welded together or connected by screws.

[0012] Preferably, the back plate has a handle passage groove, the snap-fit ​​post is provided with a handle, and the handle and the handle passage groove are positioned and matched in size.

[0013] Preferably, the handle is connected to a rotating shaft on the side facing the locking post, and the rotating shaft is rotatably connected to the locking post.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The side support legs designed in this scheme can be flipped upwards in the opposite direction, bringing the back panel and side support legs closer together, thereby reducing the overall height between the back panel and side support legs and making it easier to carry.

[0016] Further design: the handle passes through a slot, allowing the user to carry the entire easel by hand, making it convenient to carry by hand when no other means of transportation are available. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1:

[0026] Please see Figure 1-5 This utility model provides a technical solution: a folding easel for use, comprising: a back panel 1, a top panel 5, a bottom panel 3, and two side support legs 12;

[0027] The top plate 5 and bottom plate 3 are respectively connected to the upper and lower ends of the back plate 1. The two side support legs 12 are respectively located on both sides of the back plate 1. The upper end and upper middle side of the two side support legs 12 are respectively connected to a rotating shaft 13 and a snap-fit ​​post 14. The middle and lower sides of the back of the back plate 1 are respectively connected to a bearing seat 10 and an open snap-fit ​​frame 11. The rotating shaft 13 is rotatably inserted into the bearing seat 10. The snap-fit ​​post 14 and the open snap-fit ​​frame 11 are corresponding in position and matched in size.

[0028] Analysis of the above content: When in use, the two side support legs 12 are flipped downwards, so that the locking post 14 is locked into the open locking frame 11. The open locking frame 11 is made of elastic material (such as plastic or spring steel), which can lock the locking post 14 and prevent the two side support legs 12 from flipping upwards. The two side support legs 12 play a role in forming the back plate 1, top plate 5, and bottom plate 3.

[0029] Simply place the drawing board on the back panel 1, top panel 5, and bottom panel 3 to begin drawing.

[0030] Example 2:

[0031] Please see Figure 1-5 The present invention provides a technical solution based on embodiment one: a sliding groove 4 is provided in the middle of the upper surface of the back plate 1, the sliding groove 4 extends along the back plate 1 to the lower part of the back plate 1, and a telescopic mechanism that is slidably connected to the sliding groove 4 is connected to the bottom of the top plate 5.

[0032] Analysis of the above content: In use, the top plate 5 can move up and down relative to the back plate 1 through the telescopic mechanism, thereby adjusting the distance between the top plate 5 and the bottom plate 3, which is suitable for clamping drawing boards of different heights.

[0033] Example 3:

[0034] Please see Figure 1-5The present invention provides a technical solution based on Embodiment 2: the telescopic mechanism includes a cover plate 9 connected to the upper side of the sliding groove 4 by screws, a through hole is provided in the middle of the cover plate 9, a movable rod 6 is connected to the middle of the top plate 5, the movable rod 6 movably passes through the through hole, a limit ring 7 is connected to the bottom end of the movable rod 6, and a spring 8 is supported between the limit ring 7 and the cover plate 9.

[0035] Analysis of the above content: When the top plate 5 moves upward, the top plate 5 drives the movable rod 6 to move upward. Since the cover plate 9 is fixed to the upper part of the movable groove 4, the upward movement of the movable rod 6 will pull the limiting ring 7 to move upward, thereby causing the limiting ring 7 and the cover plate 9 to compress the spring 8. Under the elastic force of the spring, the drawing board clamped between the top plate 5 and the bottom plate 3 is more secure.

[0036] Example 4:

[0037] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: the back plate 1 and the bottom plate 3 are welded or connected by screws.

[0038] Analysis of the above content: Welding or screw connection is acceptable, because the back plate 1 and the bottom plate 3 only need to be fixed together, and they generally will not need to be disassembled later.

[0039] Example 5:

[0040] Please see Figure 1-5 This utility model provides a technical solution based on Embodiment 1: a handle passage groove 2 is provided on the back plate 1, and a handle 15 is provided on the locking post 14. The handle 15 corresponds to the handle passage groove 2 in position and is adapted in size. A rotating shaft 16 is connected to the side of the handle 15 facing the locking post 14, and the rotating shaft 16 is rotatably connected to the locking post 14.

[0041] Analysis of the above content: When the easel is in normal use, its shape is as follows: Figure 1 As shown, the side support legs 12 on both sides are supported on the ground. After the painting is finished, the snap-fit ​​post 14 and the opening snap frame 11 are pried apart, so that the side support legs 12 and the pivot 13 rotate counterclockwise around the pivot seat 10, so that the side support legs 12 flip up until the handle 15 passes through the handle through slot 2. Then the handle 15 is rotated so that the handle 15 spans across the handle through slot 2, so that the side support legs 12 and the back plate 1 will not separate.

[0042] A limiting ring is provided at the end of the rotating shaft 16. The locking post 14 is connected to a seat by screws. The rotating shaft 16 is inserted into the seat and is restrained by the ring, so the rotating shaft 16 will not detach from the seat (e.g., Figure 5 (As shown).
