[0033] The beneficial effect of the external plug-in device for expanding the all-in-one blackboard provided in the present embodiment is: compared with the prior art, the external plug-in device for expanding the all-in-one blackboard provided in the present embodiment can facilitate the sliding setting of two external blackboards 3 by setting an upper slide rail 1, a lower slide rail 2 and a sliding assembly. By adding the external blackboard 3, the writing area of ​​the all-in-one blackboard in the prior art is greatly improved, and the convenience of using the all-in-one blackboard is increased.

[0034] like Figure 1 and Figure 4 As shown, the sliding assembly 4 includes a slider 401 and a support plate 402, the slider 401 is slidably arranged on the upper slide rail 1 or the lower slide rail 2, the support plate 402 is arranged horizontally, and the support plate 402 is arranged to extend forward, one end of the support plate 402 is arranged on the slider 401, and the other end of the support plate 402 is arranged on the external blackboard 3. The arrangement of the support plate 402 can suspend the external blackboard 3 forward to prevent the movement of the external blackboard 3 from interfering with the all-in-one blackboard.

[0035] like Figure 2 As shown, the top and bottom ends of the external blackboard 3 are fixed with connecting plates 301, the connecting plates 301 are provided with a first connecting hole, the supporting plate 402 is provided with a second connecting hole 403, and the bolts are screwed into the corresponding first connecting holes and second connecting holes 403 to fix the supporting plate 402 to the connecting plates 301.

When two external blackboards 3 are assembled together, the interval between the first rail 101 and the second rail 102 is not greater than the distance between two adjacent sliders 401 at the tops of two different external blackboards 3. The interval between the first rail 101 and the second rail 102 can help reduce the weight of the upper slide rail 1. At the same time, since the interval between the first rail 101 and the second rail 102 is not greater than the distance between two adjacent sliders 401 at the tops of two different external blackboards 3, when the two external blackboards 3 are assembled together in the middle of the all-in-one blackboard, the slider 401 above the external blackboard 3 will not separate from the upper slide rail 1.

[0037] The lower lower rail 2 includes a third rail 201 and a fourth rail 202 that are spaced apart. When two external blackboards 3 are assembled together, the space between the third rail 201 and the fourth rail 202 is not greater than the distance between two adjacent sliders 401 at the bottom of two different external blackboards 3. The spaced arrangement of the third rail 201 and the fourth rail 202 can facilitate reducing the weight of the lower lower rail 2. At the same time, since the space between the third rail 201 and the fourth rail 202 is not greater than the distance between two adjacent sliders 401 at the bottom of two different external blackboards 3, when the two external blackboards 3 are assembled together in the middle of the integrated blackboard, the slider 401 below the external blackboard 3 will not separate from the lower rail 2.

The arrangement of the fixing member 103 can facilitate the first rail 101, the second rail 102, the third rail 201 and the fourth rail 202 to be fixedly installed on the cavities on the upper and lower sides of the all-in-one blackboard, thereby facilitating the installation of the external blackboard 3.

[0039] like Figure 2As shown, the first rail 101 and the second rail 102 have the same shape, the first rail 101 includes a first mounting plate 105 and a first guide plate 106 formed in the middle of the first mounting plate 105, and the first fixing hole 203 of the first rail 101 is set through the first guide plate 106 and the first mounting plate 105. The third rail 201 and the fourth rail 202 have the same shape, the third rail 201 includes a second mounting plate 204 and a second guide plate 205 formed in the middle of the second mounting plate 204, the first fixing hole 203 of the third rail 201 is set through the second guide plate 205 and the second mounting plate 204, the cross-section of the first guide plate 106 and the second guide plate 205 has the same shape, and the slider 401 is slidably set on the corresponding first guide plate 106 or the second guide plate 205. The provision of the first mounting plate 105 and the second mounting plate 204 can increase the strength of the upper slide rail 1 and the lower slide rail 2, and improve the bearing capacity of the upper slide rail 1 and the lower slide rail 2.

[0040] As a preferred technical solution, the cross-sections of the first guide plate 106 and the second guide plate 205 are in an "I" shape, and a slide groove is provided on the slider 401. The shape of the slide groove is adapted to the first guide plate 106 or the second guide plate 205, and the first guide plate 106 and the second guide plate 205 are both inserted into the slide grooves on the corresponding slider 401. The I-shaped arrangement of the first guide plate 106 and the second guide plate 205 enables the slider 401 to be buckled on the first guide plate 106 or the second guide plate 205, and cannot be detached from the first guide plate 106 or the second guide plate 205, and can only slide along the first guide plate 106 or the second guide plate 205.

[0041] In a possible implementation, the second guide plates 205 of the third rail 201 and the fourth rail 202 are disposed below the second mounting plate 204 to prevent dust accumulation on the second mounting plate 204 from affecting the sliding of the external blackboard 3 .

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
