[0041] It should be noted that: unless otherwise defined, the technical terms or scientific terms used herein should be understood as the usual meaning understood by those skilled in the art to which the utility model belongs. The "one", "a" or "the" and similar words used in the utility model patent application description and claims do not represent quantity limitation, but indicate that there is at least one; The "first", "second" and "third" used in this paper should not be regarded as the limitation of the order of parts, but only for distinguishing different parts; "Include" or "contain" and similar words indicate that the elements or objects appearing before "include" or "contain" cover the elements or objects listed after "include" or "contain" and their equivalents, but do not exclude other elements or objects with the same function.

[0042] In order to more clearly describe the specific structure of the plug-in touch screen, combined with the attached Figures 1-7 This embodiment is described:

[0043] As Figure 1 And Figure 7 As shown in a kind of plug-in touch screen, including touch screen 1, fixed in the back of touch screen 1 Plug-in seat 2 and with the plug-in seat 2 Plug-in cooperation receiving seat 3;Plug-in seat 2 rotationally connected with end locking mechanism 4, end locking mechanism 4 has the locking state and release state that are switched to each other, locking wall 304 is provided on receiving seat 3, locking wall 304 limits the end locking mechanism 4 in locking state and moves along the axial direction of plug-in seat 2;Plug-in seat 2 is slidably provided with protective unlocking piece 5, protective unlocking piece 5 is connected end locking mechanism 4 by transmission mechanism 6, so that end locking mechanism 4 is rotated and switched between locking state and release state;Protective unlocking piece 5 has protective rod 501 extending to the outside of the edge of touch screen 1.

[0044] Referring to Figure 2 , screw hole is reserved in the back of touch screen 1, plug-in seat 2 is directly connected with touch screen 1 by screw, receiving seat 3 is fixed to external base, and plug-in seat 2 and receiving seat 3 are connected when using, so that the fixation of touch screen can be realized.

[0045] Referring to Figure 5 , plug-in seat 2 includes base plate 201 and plug-in pipe 202, base plate 201 is fixedly connected with touch screen 1, plug-in pipe 202 is fixed on base plate 201, and the cross section of plug-in pipe 202 is rectangular, for limiting itself to rotate in receiving seat 3.

[0046] Referring to Figure 5And Figure 6 The end locking mechanism 4 comprises a rotating shaft 401 and a locking plate 402. One end of the rotating shaft 401 is rotatably connected to the base plate 201, and the rotating shaft 401 is located in the insertion pipe 202. The locking plate 402 is fixed to the other end of the rotating shaft 401. The locking plate 402 has a locking end 403 that can protrude to the outer edge of the insertion pipe 202. The locking plate 402 can rotate with the rotating shaft 401. In the release state, the locking end 403 is within the range of the insertion pipe 202 (as shown in Figure 3 or Figure 6 ). After switching to the locking state, the locking end 403 can protrude to the outside of the edge of the insertion pipe 202 (as shown in Figure 5 or Figure 7 ).

[0047] Referring to Figure 4 and Figure 7 , the receiving seat 3 comprises a receiving pipe 301, a locking pipe 302 and a flange 303 connected in sequence. The flange 303 is used to connect to an external base. The cross-sectional shape of the receiving pipe 301 is adapted to that of the insertion pipe 202, which is rectangular. The size of the locking pipe 302 is increased. A locking wall 304 that can contact the locking end 403 is formed at the connection between the receiving pipe 301 and the locking pipe 302. After the insertion seat 2 and the receiving seat 3 are butted, the locking plate 402 is located in the locking pipe 302. The locking end 403 in the locking state is clamped in the locking pipe 302. The locking wall 304 limits the outward axial movement of the locking plate 402, preventing the touch screen from falling off.

[0048] Referring to Figure 3 , in order to facilitate operation, two protection unlocking members 5 are provided, and the two protection unlocking members 5 can move synchronously towards or away from each other. When installing and dismounting the screen, both hands can operate on both sides of the screen. In order to prevent the end locking mechanism 4 from being unlocked due to accidental touch of the protection unlocking member 5, the end locking mechanism 4 can only be unlocked and switched to the release state by pulling the protection unlocking member 5 outward in the horizontal direction.

The gear 601 is fixed to the rotating shaft 401, and the rack 602 is fixed to the protection unlocking member 5. The gear 601 and the rack 602 are engaged. The linear motion of the protection unlocking member 5 is converted into the rotational motion of the end locking mechanism 4 by the gear and rack structure.

[0050] Referring to Figure 6 , a stop member 8 is arranged on the insertion seat 2 to limit the excessive movement of the rack 602. Specifically, two stop members 8 can be arranged corresponding to each rack 602, so that the movement of the rack 602 in the horizontal direction is bounded.

[0051] Referring to Figure 5 and Figure 6 In order to facilitate operation, the protection unlocking piece 5 or the rack 602 can be reset in time, and a reset spring 7 is further arranged, one end of the reset spring 7 is fixedly connected with the plug-in seat 2, the other end of the plug-in seat 2 is fixedly connected with the corresponding protection unlocking piece 5, and the reset spring 7 is in a locking state when not under force.

[0052] Referring to Figure 3 The protection rod 501 extends to the outside of the edge of the touch screen 1, and the protection rod 501 is first contacted with external objects when impacted, so as to avoid affecting the touch screen, specifically, the protection rod 501 as a whole can be designed as a “[” type, the bending part of the protection rod 501 corresponds to the four corners of the touch screen 1, and the protection rod 501 is covered with a glue layer.

[0053] The use process of the plug-in touch screen is as follows:

[0054] The protection unlocking piece 5 on both sides of the handheld touch screen 1 horizontally pulls out the protection rod 501 to make the two protection unlocking pieces 5 synchronously move away from each other, the protection unlocking piece 5 drives the linear displacement of the rack 602, the gear 601, the rotating shaft 401 and the locking plate 402 are synchronously rotated, the locking end 403 of the locking plate 402 is in the range of the plug-in pipe 202 and does not interfere with the receiving pipe 301; at this time, the plug-in seat 2 and the receiving seat 3 are butted, the plug-in pipe 202 enters the inner cavity of the receiving pipe 301, the locking plate 402 extends into the locking pipe 302, the locking end 403 is rotated to the outside of the plug-in pipe 202 and is clamped on the locking wall 304, at this time, the plug-in seat 2 and the receiving seat 3 cannot be separated;

[0055] When disassembling, the protection unlocking piece 5 on both sides of the handheld touch screen 1 horizontally pulls out to make the locking end 403 and the locking wall 304 rotate and separate, the plug-in seat 2 is pulled out from the receiving seat 3, and the separation of the touch screen 1 is realized.

[0056] The parts not described in detail in the above embodiment are prior art.

[0057] It should be noted that although the utility model has been described through the above embodiment, the utility model can also have other various implementation manners.
