Description

Technical Field

[0001] This utility model relates to the field of easel technology, and in particular to a novel easel. Background Technology

[0002] An easel is a stand used to hold a drawing board during painting and is an essential tool for the art process. To meet the practical needs of users, existing easels typically feature folding or adjustment functions for easy storage or to suit individual usage. However, existing easels are structurally complex, relying on multiple sets of rods for fixing and connecting the easels. Folding or adjusting them requires tightening and loosening numerous screws, a cumbersome process that negatively impacts the user experience. Therefore, this invention designs an easel to solve the aforementioned problems. Utility Model Content

[0003] In view of the current state of the prior art, the technical problem to be solved by this utility model is to provide a new type of easel with legs that are easy to adjust in length, so as to facilitate the user in folding up, unfolding and adjusting the easel.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a new type of easel, including telescopic legs and a connecting base, at least three telescopic legs are rotatably connected to the bottom of the connecting base, the telescopic legs include multiple sleeves that are nested together, the outer sleeve of two adjacent sleeves is the outer sleeve, and the inner sleeve is inserted into the outer sleeve, and a fixed lock is provided at the connection between the outer sleeve and the inner sleeve for switching the locked and unlocked states of the two.

[0005] The locking mechanism includes a fixing sleeve, a first wrench, and a first pressure block. The fixing sleeve is fitted onto the outer sleeve, and the first wrench is rotatably connected to the fixing sleeve. One end of the first pressure block can be disengaged from the first wrench, and the other end passes through the fixing sleeve and the outer sleeve and can be disengaged from the inner sleeve.

[0006] The first wrench has a protruding first abutting part. In the locked state, the first abutting part abuts against the first pressure block, the first pressure block abuts against the inner sleeve, and the inner sleeve is fixedly connected to the outer sleeve. In the unlocked state, the first abutting part disengages from the first pressure block, the first pressure block disengages from the inner sleeve, and the inner sleeve is slidably connected to the outer sleeve.

[0007] Furthermore, the three telescopic legs are arranged in a triangular pattern.

[0008] Furthermore, a first rotating shaft is connected to the top of the connecting seat, and a second rotating shaft is rotatably connected to the first rotating shaft, with a pawl connected to the second rotating shaft.

[0009] Furthermore, the end faces of the first rotating shaft and the second rotating shaft abut against each other, and the abutting surfaces of the two shafts are provided with mating end face teeth.

[0010] Furthermore, a central rotating shaft is included, connecting the first rotating shaft and the second rotating shaft. The two ends of the central rotating shaft are respectively provided with a first stepped surface and a second stepped surface. The second stepped surface abuts against the end of the second rotating shaft away from the first rotating shaft. The first stepped surface is located on the side of the first rotating shaft away from the second rotating shaft. A preload spring is provided between the first stepped surface and the first rotating shaft. One end of the preload spring abuts against the first stepped surface, and the other end abuts against the end of the first rotating shaft away from the second rotating shaft.

[0011] Furthermore, a positioning lock with a fixed and sliding state is fitted on the sleeve. The positioning lock includes a positioning sleeve, a second wrench, and a second pressure block. The positioning sleeve is fitted on the sleeve, and the second wrench is rotatably connected to the positioning sleeve. One end of the second pressure block can disengage from the second wrench and abut against it, while the other end passes through the positioning sleeve and can disengage from the sleeve.

[0012] The second wrench has a protruding second abutment. In the fixed state, the second abutment abuts against the second pressure block, the second pressure block abuts against the sleeve, and the positioning lock is fixedly connected to the sleeve. In the sliding state, the second abutment disengages from the second pressure block, the second pressure block disengages from the sleeve, and the positioning lock is slidably connected to the sleeve.

[0013] Furthermore, it includes a storage basket with a long, narrow groove, and two adjacent positioning locks with sliding shafts protruding in the same direction, the sliding shafts passing through the groove.

[0014] Furthermore, the top of the chute is provided with an anti-slip pad.

[0015] Compared with existing technologies, the advantages of this invention are as follows: By setting up multi-level interlocking sleeves, the length of the telescopic support leg can be adjusted, thereby realizing the functions of folding, unfolding, and height adjustment. Since the sleeves interlock when the telescopic support leg is folded, the volume of this invention is reduced, making it easier for users to store. A locking mechanism allows for sliding or fixing of the outer and inner sleeves by rotating the first lever. When the outer and inner sleeves are slidably connected, the length of the telescopic support leg can be adjusted; when they are fixedly connected, the telescopic support leg provides support, simplifying the steps for folding, unfolding, and adjusting the easel, making it more convenient to use. By rotating the telescopic support leg to the connecting seat, the user can adjust the rotation angle of the telescopic support leg, thereby adjusting the center of gravity of this invention for stable standing. When not in use, the telescopic support leg can also be rotated to fold up for easy storage. Attached Figure Description

[0025] The present invention will be further described below with reference to specific embodiments.

[0026] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship, 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, and therefore should not be construed as a limitation of this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] like Figure 1-3As shown, a novel easel includes telescopic legs 2 and a connecting base 1. At least three telescopic legs 2 are rotatably connected to the bottom of the connecting base 1. Each telescopic leg 2 includes multiple sleeves 2.1 that are nested together. Among two adjacent sleeves 2.1, the one fitted on the outside is the outer sleeve 2.1.1, and the one inserted inside the outer sleeve 2.1.1 is the inner sleeve 2.1.2. A locking lock 3 is provided at the connection between the outer sleeve 2.1.1 and the inner sleeve 2.1.2 for switching between their locked and unlocked states.

[0031] The fixed lock 3 includes a fixed sleeve 3.1, a first wrench 3.2, and a first pressure block 3.3. The fixed sleeve 3.1 is sleeved on the outer sleeve 2.1.1, and the first wrench 3.2 is rotatably connected to the fixed sleeve 3.1. One end of the first pressure block 3.3 can disengage from the first wrench 3.2, and the other end passes through the fixed sleeve 3.1 and the outer sleeve 2.1.1 and can disengage from the inner sleeve 2.1.2.

[0032] The first wrench 3.2 has a protruding first abutting part 3.2.1. In the locked state, the first abutting part 3.2.1 abuts against the first pressing block 3.3, the first pressing block 3.3 abuts against the inner sleeve 2.1.2, and the inner sleeve 2.1.2 is fixedly connected to the outer sleeve 2.1.1. In the unlocked state, the first abutting part 3.2.1 disengages from the first pressing block 3.3, the first pressing block 3.3 disengages from the inner sleeve 2.1.2, and the inner sleeve 2.1.2 is slidably connected to the outer sleeve 2.1.1.

[0033] By setting up multi-level interlocking sleeves 2.1, the length of the telescopic support leg 2 can be adjusted, thereby realizing the functions of folding, unfolding, and height adjustment of this utility model. Since the sleeves 2.1 interlock when the telescopic support leg 2 is folded, the volume of this utility model is reduced, making it easier for users to store. By setting a fixing lock 3, rotating the first wrench 3.2 in the fixing lock 3 can control the sliding or fixed connection between the outer sleeve 2.1.1 and the inner sleeve 2.1.2. When the outer sleeve 2.1.1 and the inner sleeve 2.1.2 are slidably connected, the length of the telescopic support leg 2 can be adjusted; when the outer sleeve 2.1.1 and the inner sleeve 2.1.2 are fixedly connected, the telescopic support leg 2 can be fixed to provide support, thus simplifying the steps for users to fold, unfold, and adjust the easel, making it convenient to use. By rotating the telescopic support leg 2 to the connecting seat 1, the user can adjust the rotation angle of the telescopic support leg 2, thereby adjusting the center of gravity of this utility model to ensure stable standing. When not in use, the telescopic support leg 2 can be rotated and retracted for easy storage.

[0034] By rotating the first wrench 3.2 back and forth, the first abutment part 3.2.1 on the first wrench 3.2 can move back and forth, thereby abutting or disengaging from the first pressure block 3.3, achieving a detachable abutment between the first wrench 3.2 and the first pressure block 3.3. When one end of the first pressure block 3.3 abuts against the first wrench 3.2, the pressure generated causes the other end of the first pressure block 3.3 to press against the inner sleeve 2.1.2, that is, the first pressure block 3.3 abuts against the inner sleeve 2.1.2; when the first pressure block 3.3 disengages from the first wrench 3.2, the pressure disappears, and the first pressure block 3.3 also disengages from the inner sleeve 2.1.2. The above method achieves a detachable abutment between the first pressure block 3.3 and the inner sleeve 2.1.2.

[0035] When the first pressure block 3.3 abuts against the first wrench 3.2 and the inner sleeve 2.1.2, the pressure increases the friction between the three to fix the first wrench 3.2 and the inner sleeve 2.1.2. Since the first wrench 3.2 is connected to the outer sleeve 2.1.1 through the fixing sleeve 3.1, the outer sleeve 2.1.1 and the inner sleeve 2.1.2 are fixedly connected at this time. Similarly, when the first pressure block 3.3 disengages from the first wrench 3.2 and the inner sleeve 2.1.2, the friction disappears, and the outer sleeve 2.1.1 and the inner sleeve 2.1.2 are slidably connected at this time.

[0036] By rotating the telescopic support leg 2 to the connecting base 1, the user can adjust the rotation angle of the telescopic support leg 2, thereby adjusting the center of gravity of the invention to ensure stable standing. When not in use, the telescopic support leg 2 can also be rotated and folded for easy storage.

[0037] Preferably, the telescopic support leg 2 and the connecting seat 1 can be connected by a pin, so that the telescopic support leg 2 and the connecting seat 1 are rotatably connected.

[0038] Preferably, as one embodiment, the sleeve 2.1 is provided with 4.

[0039] Preferably, the three telescopic support legs 2 are arranged in a triangle. A triangle provides stability, and this design enhances the stability of the invention when it is unfolded and erected.

[0040] Preferably, the top of the connecting seat 1 is connected to a first rotating shaft 4, which is rotatably connected to a second rotating shaft 5. A claw 6 is connected to the second rotating shaft 5, which can fix the drawing board. The angle of the drawing board can be adjusted by rotating the second rotating shaft 4, thereby meeting the various usage needs of the user.

[0041] Preferably, the end faces of the first rotating shaft 4 and the second rotating shaft 5 abut against each other, and the abutting surfaces of the two are provided with matching end face teeth, so that the first rotating shaft 4 and the second rotating shaft 5 can lock each other and prevent the drawing board from shifting due to the rotation of the second rotating shaft 5.

[0042] Preferably, the device includes a central rotating shaft 7 that connects the first rotating shaft 4 and the second rotating shaft 5. The two ends of the central rotating shaft 7 are respectively provided with a first stepped surface 7.1 and a second stepped surface 7.2. The second stepped surface 7.2 abuts against the end of the second rotating shaft 5 away from the first rotating shaft 4. The first stepped surface 7.1 is located on the side of the first rotating shaft 4 away from the second rotating shaft 5. A preload spring 8 is provided between the first stepped surface 7.1 and the first rotating shaft 4. One end of the preload spring 8 abuts against the first stepped surface 7.1, and the other end abuts against the end of the first rotating shaft 4 away from the second rotating shaft 5. The second rotating shaft 5 is limited by the second stepped surface 7.2. The preload spring 8 applies a preload force to push the first rotating shaft 4 to press the second rotating shaft 5, thereby making the end face teeth of the two tightly engaged. When the user needs to rotate the second rotating shaft 5, he only needs to overcome the preload force of the preload spring 8 to disengage the end face teeth of the first rotating shaft 4 and the second rotating shaft 5, thereby rotating the second rotating shaft 5. After the user releases his hand, the first rotating shaft 4 and the second rotating shaft 5 will re-engage due to the preload force of the preload spring 8. This design allows the user to rotate the second rotating shaft 5 by simply turning it, without the need for other operations such as loosening or tightening bolts or using a wrench.

[0043] Preferably, a positioning lock 9 with a fixed and sliding state is fitted on the sleeve 2.1. The positioning lock 9 includes a positioning sleeve 9.1, a second wrench 9.2 and a second pressure block 9.3. The positioning sleeve 9.1 is fitted on the sleeve 2.1. The second wrench 9.2 is rotatably connected to the positioning sleeve 9.1. One end of the second pressure block 9.3 can be disengaged from the second wrench 9.2, and the other end passes through the positioning sleeve 9.1 and can be disengaged from the sleeve 2.1.

[0044] The second wrench 9.2 has a protruding second abutment 9.2.1. In the fixed state, the second abutment 9.2.1 abuts against the second pressure block 9.3, the second pressure block 9.3 abuts against the sleeve 2.1, and the positioning lock 9 is fixedly connected to the sleeve 2.1. In the sliding state, the second abutment 9.2.1 disengages from the second pressure block 9.3, the second pressure block 9.3 disengages from the sleeve 2.1, and the positioning lock 9 is slidably connected to the sleeve 2.1.

[0045] By rotating the second wrench 9.2 back and forth, the second abutment portion 9.2.1 on the second wrench 9.2 can move back and forth, thereby abutting or disengaging from the second pressure block 9.3, achieving a detachable abutment between the second wrench 9.2 and the second pressure block 9.3. When one end of the second pressure block 9.3 abuts against the second wrench 9.2, the pressure generated will press the other end of the second pressure block 9.3 against the sleeve 2.1, that is, the second pressure block 9.3 abuts against the sleeve 2.1; when the second pressure block 9.3 disengages from the second wrench 9.2, the pressure disappears, and the second pressure block 9.3 also disengages from the sleeve 2.1. The above method achieves a detachable abutment between the second pressure block 9.3 and the sleeve 2.1.

[0046] When the second pressure block 9.3 abuts against the second wrench 9.2 and the sleeve 2.1, the pressure increases the friction between the three to fix the second wrench 9.2 and the sleeve 2.1. Since the second wrench 9.2 is rotatably connected to the positioning lock 9, the positioning lock 9 is fixedly connected to the sleeve 2.1 at this time. Similarly, when the second pressure block 9.3 disengages from the second wrench 9.2 and the sleeve 2.1, the friction disappears, and the positioning lock 9 is slidably connected to the sleeve 2.1 at this time.

[0047] This structure allows the positioning lock 9 to be fixed at any position on the sleeve 2.1, and the operation is simple and convenient.

[0048] Preferably, the device includes a storage basket 10 with a long, narrow groove 10.1. Two adjacent positioning locks 9 have sliding shafts 9.4 protruding in the same direction, which pass through the groove 10.1. The storage basket 10 allows the user to place art supplies. The position of the storage basket 10 can be controlled by sliding the positioning locks 9 up and down. Since the sleeve 2.1 is generally inclined in actual use, adjacent positioning locks 9 will move both up and down and left and right when sliding on the sleeve 2.1. The groove 10.1 provides space for the sliding shafts 9.4 on the positioning locks 9 to move left and right.

[0049] The storage basket 10 can be removed by pulling the slide shaft 9.4 out of the slide groove 10.1.

[0050] Preferably, a retaining edge is provided at the end of the slide shaft 9.4 away from the positioning lock 9, so that the slide shaft 9.4 is not easily disengaged from the slide groove 10.1.

[0051] Preferably, the top of the slide groove 10.1 is provided with an anti-slip pad 10.2. After the user places an item in the storage basket 10, the friction between the sliding shaft 9.4 and the slide groove 10.1 increases due to increased pressure. The anti-slip pad further increases this friction, thereby preventing the storage basket 10 from sliding. When the user needs to adjust the position of the storage basket 10, they only need to remove the item from the storage basket 10 or lift the storage basket 10, which reduces the pressure between the sliding shaft 9.4 and the top of the slide groove 10.1, thereby reducing the friction between them and allowing the sliding shaft 9.4 to slide in the slide groove 10.1.

[0052] Preferably, anti-slip material can be provided on the surfaces of the first pressing block 3.3 and the second pressing block 9.3 to enhance their friction during operation.

[0053] The method of using this utility model is as follows: By rotating the first wrench 3.2 back and forth, the outer sleeve 2.1.1 and the inner sleeve 2.1.2 are slidably or fixedly connected. When the outer sleeve 2.1.1 and the inner sleeve 2.1.2 are slidably connected, the length of the telescopic support leg 2 can be adjusted; when the outer sleeve 2.1.1 and the inner sleeve 2.1.2 are fixedly connected, the telescopic support leg 2 is fixed to provide support. By adjusting the rotation angle of the telescopic support leg 2, the center of gravity of this utility model can be adjusted. By rotating the second rotating shaft 4.2, the angle of the drawing board can be adjusted. By sliding the positioning lock 9 up and down, the position of the storage basket 10 can be controlled.

[0054] The advantages of this invention are as follows: By setting up multi-level interlocking sleeves 2.1, the length of the telescopic support leg 2 can be adjusted, thereby realizing the functions of folding, unfolding, and height adjustment. Since the sleeves 2.1 interlock when the telescopic support leg 2 is folded, the volume of this invention is reduced, making it easier for users to store. By setting a fixing lock 3, rotating the first wrench 3.2 in the fixing lock 3 can control the sliding or fixed connection between the outer sleeve 2.1.1 and the inner sleeve 2.1.2. When the outer sleeve 2.1.1 and the inner sleeve 2.1.2 are slidably connected, the length of the telescopic support leg 2 can be adjusted; when the outer sleeve 2.1.1 and the inner sleeve 2.1.2 are fixedly connected, the telescopic support leg 2 can be fixed to provide support, thus simplifying the steps for users to fold, unfold, and adjust the easel, making it more convenient to use. By rotating the telescopic support leg 2 to the connecting seat 1, the user can adjust the rotation angle of the telescopic support leg 2, thereby adjusting the center of gravity of this invention to ensure stable standing. When not in use, the telescopic support leg 2 can be rotated and retracted for easy storage.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
