The lower frame, except for the difference in length between the upper frame and the lower frame, all have the same shape and size; any two groups of adjacent frames 1 are detachably connected by a connector 2; the top of the frame 1 is in its length direction A slide rail and a hook assembly 3 are provided. The hook assembly 3 is clamped in the slide rail and can slide along the length of the slide rail. The writing board can be hung on the wall through the hook assembly 3; There is also a stopper that restricts the sliding of the hook assembly 3 at the position connected to the slide rail of the frame 1, and the hook assembly 3 can be installed and taken out by taking out or loading the stopper.
为了实现边框1与连接件2之间更加便捷的可拆卸连接，在一个实施例中，如图2-5所示，所述边框1包括沿边框1长度方向设置在边框1顶部的通孔11，所述连接件2包括连接件本体21以及一对水平方向和竖直方向固定在连接件本体21上的插舌22，插舌22的尺寸与通孔11的大小相适配，两组插舌22在其长度方向上垂直设置，将水平方向的插舌22***水平边框1的通孔11中，而竖直方向的插舌22***竖直边框1的通孔11中，这样便可实现连接件2与边框1之间的连接。当然，生产商在实际的生产装配过程中，还可在将插舌22***对应通孔11之后使其稳定粘接固定，进而进一步保证整体使用的稳定性。In order to achieve a more convenient detachable connection between the frame 1 and the connecting member 2, in one embodiment, as shown in FIGS. 2-5, the frame 1 includes a through hole 11 provided on the top of the frame 1 along the length direction of the frame 1. The connecting piece 2 includes a connecting piece body 21 and a pair of plug tongues 22 fixed on the connecting piece body 21 in the horizontal and vertical directions. The size of the plug tongue 22 is adapted to the size of the through hole 11, and the two sets of plugs The tongue 22 is vertically arranged in its length direction, and the horizontal tongue 22 is inserted into the through hole 11 of the horizontal frame 1, and the vertical tongue 22 is inserted into the through hole 11 of the vertical frame 1, so that it can be realized The connection between the connecting piece 2 and the frame 1. Of course, in the actual production and assembly process, the manufacturer can also stably bond and fix the tongue 22 after inserting it into the corresponding through hole 11, thereby further ensuring the stability of the overall use.
为了实现边框1与书写板本体之间更好的安装，在使用过程中整体更加稳定，进一步的，边框1底部在垂直方向上还设有与书写板本体厚度相适配的卡槽12，这样在整体装配过程中，将书写板本体卡入边框1的卡槽12中，便可使得书写板本体与边框1之间稳定性更高，而且也十分便于后续连接件2的安装。In order to achieve a better installation between the frame 1 and the writing board body, the whole is more stable during use. Further, the bottom of the frame 1 is also provided with a card slot 12 in the vertical direction that matches the thickness of the writing board body. During the overall assembly process, the writing board body is clamped into the card slot 12 of the frame 1 to make the stability between the writing board body and the frame 1 higher, and it is also very convenient for subsequent installation of the connector 2.
普通的书写板边角为直角，很容易导致授课者在使用过程中划伤或者戳伤 用户，安全性较低，因此为了使得书写板整体安全性能更高，在又一实施例中，所述连接件本体21在其背离书写板本体一侧呈圆弧面设置，在将连接件本体21安装于相邻两边框1之间后，连接件本体21***表面为圆弧状，这样便可克服授课者拿取书写板时造成划伤的问题；另外，为了加强连接件本体21与书写板本体之间连接的紧密性，使整体稳定性更高，连接件本体21在其靠近书写板本体一侧还设有两组夹板23，两组夹板23之间的间距与书写板本体的厚度相适配，将书写板本体卡入两组夹板23之间，可提高连接件本体21与书写板本体之间的关联性，整体结构稳定性更高。The corners of the ordinary writing board are right angles, which can easily cause the lecturer to scratch or poke the user during use, and the safety is low. Therefore, in order to make the overall safety performance of the writing board higher, in another embodiment, the The connector body 21 is arranged on the side facing away from the writing board body in an arc surface. After the connector body 21 is installed between two adjacent frames 1, the peripheral surface of the connector body 21 is arc-shaped, which can overcome The problem of scratches when the lecturer takes the writing board; in addition, in order to strengthen the tightness of the connection between the connector body 21 and the writing board body, and to make the overall stability higher, the connector body 21 is close to the writing board body. There are also two sets of splints 23 on the side. The spacing between the two sets of splints 23 is adapted to the thickness of the writing board body. The writing board body is clamped between the two sets of splints 23 to improve the connecting piece body 21 and the writing board body. The correlation between the two, the overall structural stability is higher.
为了实现阻挡件对挂钩组件3良好的限制，同时保证整体结构稳定性好，在又一实施例中，所述阻挡件包括覆盖在一组插舌22表面上的卡位板24，卡位板24固定安装在插舌22位于其远离边框1一端，作为优选的，卡位板24与连接件本体21一体成型，所述卡位板24厚度大于边框1顶部的厚度，这样在挂钩组件3滑动到边框1的一端之后可受到卡位板24的限制，挂钩组件3不会继续滑出边框1；所述阻挡件还包括可拆卸安装在另一组插舌22上的活动限位板25，活动限位板25的厚度大于边框1顶部的厚度，这样在挂钩组件3滑动到边框1的另一端之后可受到活动限位板25的限制，挂钩组件3也不会继续滑出边框1。而通过上述设置之后，在需要将挂钩组件3取出或者安装时，仅需要对连接件本体21一侧的活动限位板25进行拆卸或者安装即可，而无需对边框1两端的阻挡件进行拆装，从而减少了工作量，提高了操作效率。In order to achieve a good restriction on the hook assembly 3 by the stopper, and at the same time ensure good stability of the overall structure, in another embodiment, the stopper includes a detent plate 24 covering the surface of a set of tongues 22, a detent plate 24 is fixedly mounted on the tongue 22 at one end away from the frame 1. As a preference, the retaining plate 24 is integrally formed with the connector body 21. The thickness of the retaining plate 24 is greater than the thickness of the top of the frame 1, so that it slides on the hook assembly 3. After reaching one end of the frame 1, it can be restricted by the retaining plate 24, and the hook assembly 3 will not continue to slide out of the frame 1. The blocking member also includes a movable limit plate 25 that can be detachably installed on another set of tongues 22, The thickness of the movable limit plate 25 is greater than the thickness of the top of the frame 1, so that after the hook assembly 3 slides to the other end of the frame 1, it can be restricted by the movable limit plate 25, and the hook assembly 3 will not continue to slide out of the frame 1. After the above settings, when the hook assembly 3 needs to be removed or installed, only the movable limit plate 25 on the side of the connector body 21 needs to be removed or installed, without removing the barriers at both ends of the frame 1. Installation, thereby reducing the workload and improving the operating efficiency.
为了方便对活动限位板25进行安装，在又一实施例中，所述活动限位板25包括与插舌22尺寸相适配的弧形板251，弧形板251由具有张紧弹力的塑料制成，安装时弧形板251可发生一定的扩张形变；弧形板251的厚度大于边框1顶部的厚度，这样在挂钩组件3滑动到边框1的另一端之后可受到活动限位板25的限制，挂钩组件3也不会继续滑出边框1；弧形板251两端的内侧设有榫头253，连接件本体21上位于插舌22的下方还设有与所述榫头253相适配的榫槽26，将榫头253卡入到榫槽26中之后，活动限位板25便可卡入到连接件本体21相应位置。在装配过程中，首先将挂钩组件3滑入到边框1的滑轨中，再将活动限位板25的榫头253卡入到连接件本体21的榫槽26内；而之后将插 舌22***边框1的通孔，这样便可通过限制活动限位板25限制挂钩组件3的移动。In order to facilitate the installation of the movable limit plate 25, in another embodiment, the movable limit plate 25 includes an arc-shaped plate 251 that is adapted to the size of the tongue 22. The arc-shaped plate 251 is made of a tensioned elastic Made of plastic, the arc-shaped plate 251 can undergo a certain expansion and deformation during installation; the thickness of the arc-shaped plate 251 is greater than the thickness of the top of the frame 1, so that the hook assembly 3 can be affected by the movable limit plate 25 after sliding to the other end of the frame 1. The hook assembly 3 will not continue to slide out of the frame 1; the inner sides of the two ends of the arc-shaped plate 251 are provided with tenons 253, and the connector body 21 is located under the tongue 22 and is also equipped with the tenon 253.
