[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] See also Figure 1-Figure 2 , respectively, are schematic diagrams of the overall structure of the connector of the present invention. Among them, according to a connector of the present invention, the connector includes a U-shaped base, the U-shaped base has a first end face 1 and a second end face 2 that are arranged opposite to each other, the first end face 1 is provided with a plug-in portion 11 adapted to the profile, the second end face 2 is provided with a plug-in limiting hole 12, so as to be connected to the rotating shaft through the plug-in limiting hole 12, and the bottom end face of the U-shaped base is provided with a clamping portion 13, and the clamping portion 13 is used to be clamped and fixed with the support member.
[0033] Through the plug-in portion 11 and the clamping portion 13 on the connector, plug-in installation can be achieved, and installation and disassembly are simple and convenient, thus realizing a new assembly method.
[0034] The shaft is inserted into the plug-in limit hole 12, and the friction between the two is used to achieve fixation. However, this fixing method may be somewhat unstable. Therefore, in a possible implementation method, the inner walls of the plug-in limit hole 12 are respectively provided with inner convex limit grooves 121. The inner convex limit grooves 121 on the inner walls of the plug-in limit hole 12 are arranged opposite to each other, and cooperate with the grooves on the shaft, so that the shaft can be forced from two opposite directions to achieve a further stable connection effect.
[0035] On the basis of the above, if the load-bearing capacity is large, a more stable connection and fixing effect needs to be provided. Therefore, in a possible implementation, one or more through holes 122 are further provided on the ring wall at the bottom end of the plug-in limit hole 12. The provision of the through hole is mainly used to tighten and lock the rotating shaft by passing a screw through the through hole. In this case, the through hole can be provided as a threaded hole. A corresponding through hole (threaded hole) can also be provided on the rotating shaft, and a screw is screwed in to tighten the rotating shaft and the plug-in limit block so that the two will not loosen or rotate.
[0036] In order to increase the connection stability between the rotating shaft and the plug-in limiting hole, another method that can be adopted is to set at least one convex strip 123 along the inner wall of the plug-in limiting hole 12. The convex strip strengthens the friction between the rotating shaft and the plug-in limiting hole, thereby increasing the connection stability effect.
[0037] It should be noted that among the above different methods of enhancing the connection stability effect, one or more methods can be selected in combination, depending on the specific usage scenario requirements.
[0038] See also Figure 2-Figure 7 As shown, the writing board assembly of the present invention includes the above-mentioned connecting member 10, L-shaped bracket 20, support rod 30 and writing board body 40. The L-shaped bracket 20 includes a rotating shaft 101 and a vertical rod 102 vertically arranged with the rotating shaft 101. The top of the vertical rod 102 is plugged into the support rod 30. The top of the support rod 30 is provided with the writing board body 40. The rotating shaft 101 is adapted to the plug-in limit hole 12 of the connecting member 10 to achieve connection. The circumferential rotation of the writing board body is achieved by rotating the support rod 30 relative to the vertical rod 102.
[0039] The support rod of the writing board assembly can rotate 360 degrees relative to the vertical rod, so that the writing board body can rotate circumferentially to meet the needs of using the writing board at different angles.
[0040] In one possible implementation, a groove 012 adapted to the inner convex limiting groove 121 of the plug-in limiting hole 12 is provided at the bottom end of the rotating shaft 101, and the inner convex limiting groove 121 is inserted into the groove 012 to achieve limiting fixation.
[0041] During the assembly process, the rotating shaft is inserted into the plug-in limit hole, and the initial limit fixation effect is achieved based on the cooperation between the groove and the inner convex limit groove. Combined with the friction between the rotating shaft and the plug-in limit hole, the initial assembly limit fixation can basically be met.
[0042] Among them, in a possible implementation, a locking screw hole 011 is provided at the bottom end of the rotating shaft 101 corresponding to the position of the plug-in limit hole 12. The locking screw is screwed into the through hole of the plug-in limit hole and the locking lock hole to lock the rotating shaft and the plug-in limit hole. The locking screw hole and the through hole are provided correspondingly, and there can be one or more.
[0043] In order to improve the quality and load-bearing performance of the entire writing board assembly, a reinforcing part 021 is welded to the top of the vertical rod 102, and the top of the reinforcing part 021 is plugged and fixed to the support rod 30. Specifically, the outer diameter of the lower column of the reinforcing part is adapted and clamped to the inner diameter of the column of the vertical rod, the outer diameter of the middle column is equivalent to the outer diameter of the column of the vertical rod, and the outer diameter of the upper column is adapted and clamped to the inner diameter of the column of the support rod.
[0044] In one possible implementation, a sound insulation sleeve 50 is sleeved between the inner wall of the vertical rod 102 and the reinforcing vehicle part 021. In correspondence with the position of the sleeve, a limiting groove is provided on the inner wall of the vertical rod to limit the sound insulation sleeve between the inner wall of the vertical rod and the reinforcing vehicle part. By providing the sound insulation sleeve, the support rod can be prevented from making noise during rotation, and the support rod and the vertical rod can be effectively prevented from being damaged by long-term direct friction, thereby extending the service life of the product. Even if the sound insulation sleeve is damaged, it can be repaired at a minimum cost.
[0045] In order to prevent the reinforcement part from loosening, the locking screw 211 can be further matched with the notch 212 on the reinforcement part 021 to limit the locking. The locking screw is screwed in and just stuck in the notch, so that the reinforcement part can be well locked in position.
[0046] In one possible implementation, one or more silicone rings 60 are further provided on the outer wall of the reinforcing component 021. The silicone rings are provided to provide a damping effect during the rotation of the support rod, a better gap, and a better hand feel. In the position where the silicone ring is provided on the outer wall of the reinforcing component, a groove for accommodating the silicone ring can be provided.
[0047] Among them, in a possible implementation, the vertical rod 102 is also provided with a hook 022. Through the design of the hook, it is convenient to hang some daily small items during the use of the writing board assembly.
[0048] Among them, in a possible implementation, in order to enhance the load-bearing capacity of the writing board body, a reinforcing sheet metal part 70 is further provided on the bottom surface of the writing board body 40. By providing the reinforcing sheet metal part, the load-bearing performance of the writing board body can be further improved and the quality of the writing board body can be ensured to be more reliable. The reinforcing sheet metal part can be directly welded to the writing board body or fastened by screws.
[0049] The writing board assembly of the utility model can be applied to the sides of various furniture, such as chairs, tables, etc. Figure 8 As shown, the writing board assembly can be installed on the side of the chair. It is easy to install and the writing board can be rotated according to different required angles to meet the needs of use at different angles.
