Description

Technical Field

[0001] The utility model relates to the technical field of furniture and is a detachable supporting piece. Background Art

[0002] The mortise and tenon structure is a commonly used connection method in traditional Chinese architecture and furniture. It is mainly used between two wooden components and adopts a concave and convex connection method. Among them, the protruding part is called the tenon (or tenon head), and the concave part is called the mortise (or mortise, tenon groove). The mortise and tenon structure plays a connecting role through the bite of the tenon and the mortise. This connection method is not only widely used in ancient Chinese buildings, but also one of the important crafts in the production of traditional Chinese furniture. There are many types of mortise and tenon structures, including the cross connection of straight materials, the corner connection of curved straight materials, the running pin, the copy tenon, the cross intersection of curved straight materials, and the corner connection of flat plate tenon. These different types of mortise and tenon structures can be selected and applied according to different needs and scenarios.

[0003] In some commonly used wooden furniture, the mortise and tenon structure is a unique and important connection method. It does not require the use of auxiliary materials such as nails or glue, and only uses the morphological structure of the wood itself to achieve a tight connection. One type of mortise and tenon structure is to pass a cylindrical wooden pin through two perpendicular square wooden strips connected together by mortise and tenon, so that the two square wooden strips do not separate. However, during the installation process, for the convenience of installation, there will be a certain gap between the mortise and tenon structures of the two square wooden strips, which makes the two square wooden strips rotate along the wooden pin, making their stability and durability worse.

[0004] The existing support members are generally composed of a support plate and a support column. The support column is directly fixedly installed at the lower end of the support plate to support the support plate. Only the upper end surface of the support column interacts with the lower end of the support plate, and the contact surface is small. When the support plate is subjected to a large force, the support column is subjected to a large force during the long-term use of the support member, and the support member is easily damaged. In addition, the existing support members are generally assembled by the manufacturers themselves and then sold. In this era of popular e-commerce and online shopping, most support members (such as tables and stools) need to be assembled by users themselves. However, during the assembly process, it is easy to be difficult to install the support members due to lack of relevant assembly tools or insufficient assembly experience, which leads to poor use and easy damage of the support members during subsequent use. Summary of the invention

[0005] The utility model provides a detachable support member, which overcomes the deficiencies of the prior art and can effectively solve the problems of poor stability and easy damage of the prior support member.

[0006] The technical solution of the utility model is achieved through the following measures: a detachable support member, including a support column and a cylindrical support plate, at least two downward-opening mounting grooves are distributed along the circumferential direction on the lower side of the support plate, there is an angle between the central axis of each mounting groove and the central axis of the support plate, a spherical crown-shaped connecting ball is fixed to the upper inner wall of each mounting groove, a support column is coaxially mounted in each mounting groove, a ball socket with an upward opening and matching the connecting ball is provided on the upper end surface of the support column, and the inner wall of the ball socket and the outer side of the connecting ball are fitted together.

[0007] The following are further optimizations and / or improvements to the above utility model technical solution:

[0008] The lower side of the support plate may be provided with three mounting grooves spaced apart along the circumference, and the angle between the central axis of each mounting groove and the central axis of the support plate is 12° to 15°.

[0009] A triangular connecting frame may be provided below the supporting plate, and a limiting sleeve is fixedly installed at each corner of the connecting frame, and the outer side of the lower part of each supporting column is tightly sleeved in the limiting sleeve at the corresponding position.

[0010] A connecting screw hole opening downward may be provided in the center of the lower part of the connecting ball, and a connecting screw rod is fixedly installed in the center of the ball socket, and each connecting screw rod is screwed into the connecting screw hole at a corresponding position.

[0011] A wear-resistant sleeve may be fixedly installed on the outer side of the lower end of the support column at the position below the corresponding connecting frame.

[0012] The utility model has a reasonable and compact structure, and the inner wall of the ball socket and the outer side of the connecting ball fit together. The setting of the connecting ball and the ball socket can increase the contact area between the support column and the support plate after cooperating with each other, making the support member more firm, and the support column is coaxially installed in the installation groove, and there is an angle between the central axis of the installation groove and the central axis of the support plate, so that the support column cannot rotate around the central axis of the support plate, and can only rotate around its own axis, reducing the range of movement of the support column; if sitting on the support plate, the support column is more stable under the joint action of the inner wall of the installation groove and the connecting ball, and the connection between the support column and the support plate will not rotate or slide, so that the durability of the support member is stronger.

DETAILED DESCRIPTION

[0022] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0023] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached manual. Figure 1 The layout is described in detail, such as the positional relationship of front, back, top, bottom, left, right, etc., which is based on the attached manual. Figure 1 It is determined by the layout direction.

[0024] The present invention is further described below in conjunction with the embodiments and drawings:

[0025] Embodiment 1: As shown in the attached Figures 1 to 8 As shown, the detachable support member includes a support column 2 and a cylindrical support plate 1. At least two downward-opening mounting grooves 3 are distributed circumferentially at intervals on the lower side of the support plate 1. There is an angle between the central axis of each mounting groove 3 and the central axis of the support plate 1. A spherical crown-shaped connecting ball 4 is fixed to the upper inner wall of each mounting groove 3. A support column 2 is coaxially mounted in each mounting groove 3. A ball socket 5 with an upward opening and matching the connecting ball 4 is provided on the upper end surface of the support column 2, and the inner wall of the ball socket 5 and the outer side of the connecting ball 4 are fitted together.

[0026] During use, the inner wall of the ball socket 5 and the outer side of the connecting ball 4 fit together. The setting of the connecting ball 4 and the ball socket 5 can increase the contact area between the support column 2 and the support plate 1 after cooperating with each other, making the support member more solid. The support column 2 is coaxially mounted in the mounting groove 3, and there is an angle between the central axis of the mounting groove 3 and the central axis of the support plate 1. This makes it impossible for the support column 2 to rotate around the central axis of the support plate 1 and can only rotate around its own axis, reducing the range of movement of the support column 2. If pressed on the support plate 1, the support column 2 is more stable under the joint action of the inner wall of the mounting groove 3 and the connecting ball 4, and the connection between the support column 2 and the support plate 1 will not rotate or slide, making the support member more durable and facilitating the disassembly and assembly between the support column 2 and the support plate 1.

[0027] According to the requirements, the connecting ball 4 is hemispherical. When two downward-opening mounting grooves 3 are distributed along the circumference of the lower side of the support plate 1, two detachable supports spaced apart on the left and right are fixedly connected together by a connecting rod to make a clothes drying rack; when two downward-opening mounting grooves 3 are distributed along the circumference of the lower side of the support plate 1, a connecting plate is installed at intervals below the support plate 1, and a mounting hole matching the support column 2 is provided on the connecting plate, and the central axis of the mounting hole is colinear with the central axis of the support column, so that a wooden ladder can be made; the support plate 1 can be cylindrical or square, so that the detachable support can be made into a round table, round stool or square table, square stool; the support plate 1 can also be annular, such as the support plate 1 is a circular ring or a polygonal ring, so that it can be made into a shelf for placing flower pots.

[0028] The above-mentioned detachable support member can be further optimized and / or improved according to actual needs:

[0029] Embodiment 2: As an optimization of the above embodiment, as shown in the attached Figure 1 , 3 As shown in FIGS. 6, 7 and 8, three mounting grooves 3 are spaced apart along the circumference of the lower side of the support plate 1, and the angle between the central axis of each mounting groove 3 and the central axis of the support plate 1 is 12° to 15°.

[0030] According to the requirements, the angle between the central axis of each mounting groove 3 and the central axis of the support plate 1 is 15°, and the angle between the lower end face of the support column 2 and the central axis of the support column 2 is 75°. In this way, after installation, the lower end face of the support column 2 is parallel to the lower side face of the support plate 1. There are three mounting grooves 3 distributed along the circumference of the lower side of the support plate 1. An arc-shaped backrest is fixed to the outer side of the upper end of the support plate 1 between two of the mounting grooves 3, which can improve the sense of use. In this embodiment, the detachable support member is a round stool. During use, the mounting groove 3 and the lower end face of the support column 2 are both inclined surfaces, so that the installed support plate 1 is horizontal, and the support column 2 can only rotate along the inner wall of the mounting groove 3 under the action of the mounting groove 3. However, when a person sits on the support plate 1, the lower end face of the support column 2 fits the ground, so that the support column 2 cannot rotate, thereby improving the stability of the support member.

[0031] Embodiment 3: As an optimization of the above embodiment, as shown in the attached Figures 1 to 5 As shown, a triangular connecting frame 8 is provided below the supporting plate 1, and a limiting sleeve 9 is fixedly installed at each corner of the connecting frame 8, and the outer side of the lower part of each supporting column 2 is tightly sleeved in the limiting sleeve 9 at the corresponding position.

[0032] During use, the phenomenon that the distance between the support columns 2 gradually increases can be avoided. When sitting on the support plate 1, the connecting frame 8 is also used to support the soles of the feet, which meets the usage habits of some people. According to the needs, the central axis of the limiting sleeve 9 is collinear with the central axis of the support column 2 at the corresponding position, the connecting frame 8 can be annular, the connecting frame 8 can also be a plate-like structure, and the thickness of the connecting frame 8 is consistent with the height of the limiting sleeve 9. The connecting frame 8 and the limiting sleeve 9 are integrally arranged, so that a double-layer support surface can be arranged.

[0033] Embodiment 4: As an optimization of the above embodiment, as shown in the attached Figure 3 , 6 As shown in FIGS. 7 and 8 , a connecting screw hole 6 opening downward is provided in the center of the lower part of the connecting ball 4 , and a connecting screw rod 7 is fixedly installed in the center of the ball socket 5 , and each connecting screw rod 7 is screwed into the connecting screw hole 6 at the corresponding position.

[0034] According to the requirements, the central axis of the connecting screw hole 6, the central axis of the connecting screw rod 7, the central axis of the installation groove 3 and the central axis of the support column 2 are coaxially arranged. In the process of use, through such an arrangement, after installation, the connecting screw rod 7 is screwed into the connecting screw hole 6, which can improve the stability between the connecting screw rod 7 and the connecting ball 4. Under the joint action of the connecting screw rod 7, the connecting ball 4 and the ball socket 5, the stability of the connection between the support plate 1 and the support column 2 can be improved.

[0035] Embodiment 5: As an optimization of the above embodiment, as shown in the attached Figures 1 to 5 As shown, a wear-resistant sleeve 10 is fixedly installed on the outer side of the lower end of the support column 2 corresponding to the position below the connecting frame 8.

[0036] During use, installing the wear-resistant sleeve 10 can, on the one hand, improve the wear resistance of the support column 2 and extend the service life of the support column 2, and on the other hand, reduce the noise during movement and improve the use experience.

[0037] The above technical features constitute the embodiments of the present utility model, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
