[0035] The anti-falling connecting piece 300 comprises a connecting piece base plate 310, and the connecting piece base plate 310 is in the shape of a thin plate. The connecting piece base plate 310 is provided with a connecting screw hole 312 and a tension spring 313. The tension spring 313 is elastically protruded from one side surface of the connecting piece base plate 310.
[0036] The support 100 is provided with a left vertical rod 111 and a right vertical rod 121. The writing board 200 is arranged between the left vertical rod 111 and the right vertical rod 121. The anti-falling connecting piece 300 is arranged between the writing board 200 and the left vertical rod 111 and between the writing board 200 and the right vertical rod 121.
[0037] The writing board 200 is connected with the left vertical rod 111 and the right vertical rod 121 through the anti-falling connecting piece 300. Specifically, the writing board 200 is provided with a connecting groove 211 extending upward and downward on the left and right sides, and the connecting piece base plate 310 is embedded in the connecting groove 211. The left vertical rod 111 and the right vertical rod 121 are both provided with a connecting screw 140, and the connecting screw 140 is threadedly connected with the connecting screw hole 312.
[0038] In actual use, the left and right ends of the writing board 200 are connected with the left and right vertical rods 111 and 121 through the anti-falling connecting piece 300, so that the writing board 200 is fixedly connected with the support 100 to realize installation. The connecting screw 140 is screwed into the connecting hole 312, so that the anti-falling connecting piece 300 can be locked and fixed with the left and right vertical rods 111 and 121, thereby the writing board 200 is abutted through the connecting piece base plate 310 to realize the installation and connection of the writing board 200 with the support 100. When the connecting screw 140 is loosened, the connecting piece base plate 310 can slide along the connecting groove 211, so as to realize the height adjustment of the writing board 200 relative to the support 100. During the adjustment and installation of the writing board 200, the tension spring 313 can be elastically abutted in the connecting groove 211, so as to increase the friction between the connecting piece base plate 310 and the connecting groove 211, thereby avoiding the direct falling of the writing board 200 and causing injury.
[0039] In the embodiment, the writing board 200 is in the shape of a rectangular flat plate.
[0040] The writing board 200 comprises a frame 210 and a plate body 220. The plate body 220 is in the shape of a rectangular plate, and the frame 210 is arranged along the edges of the plate body 220. The frame 210 is made of aluminum profile. The frame 210 has four pieces. The four pieces of the frame 210 are respectively arranged on the four edges of the plate body 220 to form a rectangular frame. The plate body 220 is fixedly embedded in one end of the cross section of the frame 210, and the connecting groove 211 is arranged in the other end of the cross section of the frame 210. The four corners of the plate body 220 are provided with corner pieces 230. The end portions of the adjacent two pieces of the frame 210 are fixedly connected with the corner pieces 230.
[0041] On the cross section of the frame 210, the connecting groove 211 has an opening 212, and the connecting hole 312 is arranged in the center of the connecting piece base plate 310 and aligned with the opening 212. In the embodiment, the connecting piece base plate 310 and the tension spring 313 are an integral molded piece. The connecting piece base plate 310 is a metal plate product. The tension spring 313 is cut from the connecting piece base plate 310. One end of the tension spring 313 is connected with the connecting piece base plate 310, and the other end protrudes from the connecting piece base plate 310.
[0042] Referring to the drawings Figure 1, the tension elastic pieces 313 are arranged in pairs on both sides of the plate surface of the connecting piece substrate 310, so that the connecting piece substrate 310 is uniformly stressed in its thickness direction. The connecting piece substrate 310 is provided with multiple pairs of the tension elastic pieces 313, and the multiple pairs of the tension elastic pieces 313 are arranged along the plate surface of the connecting piece substrate 310. The multiple pairs of the tension elastic pieces 313 arranged in this way can be more conveniently inserted into the connecting groove 211, and can simultaneously abut against the connecting groove 211 to make the acting force distribution between the connecting piece substrate 310 and the connecting groove 211 uniform.
[0043] When the connecting piece substrate 310 is embedded in the connecting groove 211, the tension elastic piece 313 elastically abuts against the bottom of the connecting groove 211, and one side plate surface of the connecting piece substrate 310 away from the tension elastic piece 313 abuts against the top of the connecting groove 211.
[0044] In this embodiment, the bracket 100 includes: a left frame body 110, a right frame body 120 and a cross beam 130. The left vertical rod 111 is arranged on the left frame body 110. The right vertical rod 121 is arranged on the right frame body 120. Refer to the attached Figure 5 and 6 , both the left frame body 110 and the right frame body 120 are in the shape of "丄". The lower ends of the left frame body 110 and the right frame body 120 both have horizontally arranged feet. The left vertical rod 111 and the right vertical rod 121 are perpendicular to the feet and extend in the up and down direction.
[0045] The cross beam 130 is arranged between the left frame body 110 and the right frame body 120, and the cross beam 130 extends in the left and right direction. The left and right ends of the cross beam 130 are respectively connected to the left vertical rod 111 and the right vertical rod 121. The cross beam 130 connects the left frame body 110 and the right frame body 120 to form a stable support structure, and forms a space for installing and accommodating the writing board 200 between the left vertical rod 111 and the right vertical rod 121.
[0046] In this embodiment, the two ends of the cross beam 130 are respectively detachably connected to the left vertical rod 111 and the right vertical rod 121 by bolts. The length dimension of the cross beam 130 is the same as the long side dimension or the short side dimension of the writing board 200. As Figure 3 and Figure 7 shown, in actual use, the user can replace the cross beam 130 with different lengths according to his own needs, so that the writing board 200 can be used horizontally or vertically.
[0047] In some other embodiments, the cross beam 130 is in a telescopic structure. The cross beam 130 comprises a first beam body and a second beam body telescopically connected with each other along the left-right direction. The first beam body and the second beam body are locked by a pin or a screw perpendicular to the left-right direction, so that the distance between the two ends of the first beam body and the second beam body away from each other can be adjusted according to requirements.
[0048] The left upright 111 and the right upright 121 of the embodiment are both metal square tubes with rectangular cross sections. The connecting member base plate 310 is provided with connecting columns 311 at the upper and lower ends thereof. The left upright 111 and the right upright 121 are provided with clamping holes corresponding to the connecting columns 311. The connecting columns 311 are embedded in the clamping holes one by one.
[0049] Specifically, the right side of the left upright 111 and the left side of the right upright 121 are both provided with two clamping holes arranged in an upper and lower spaced manner. The two connecting columns 311 at the upper and lower ends of the connecting member base plate 310 are respectively embedded in the two clamping holes, so that the anti-falling connecting member 300 can be kept relatively stationary with the left upright 111 and the right upright 121 in the up-down direction, facilitating the height adjustment by the relative displacement of the anti-falling connecting member 300 and the writing board 200.
[0050] The connecting screw holes 312 are coaxially arranged in the connecting columns 311, and the connecting screws 140 are coaxially arranged in the clamping holes and the connecting screw holes 312. In the embodiment, the connecting columns 311 are welded and fixed to the connecting member base plate 310, and the connecting screw holes 312 coaxially pass through the connecting columns 311 and the connecting member base plate 310. The connecting screws 140 pass through the left upright 111 or the right upright 121 from the side away from the writing board 200 and are threadedly connected with the connecting screw holes 312.
[0051] It is worth noting that the connecting columns 311 and the tensioning spring plates 313 are respectively arranged on the two side surfaces of the connecting member base plate 310. Specifically, the tensioning spring plates 313 are arranged on the side of the connecting member base plate 310 facing the writing board 200, and the connecting columns 311 are arranged on the other side of the connecting member base plate 310. When the connecting screws 140 lock the connecting columns 311 along the axial direction through the connecting screw holes 312, the side surface of the connecting member base plate 310 provided with the connecting columns 311 can abut against the connecting groove 211, so that the writing board 200 can be pressed against the left upright 111 or the right upright 121, realizing the fixation of the writing board 200 without compressing the tensioning spring plates 313. The tensioning spring plates 313 can elastically abut against the other side of the connecting groove 211, realizing the anti-falling function during the adjustment of the writing board 200.
