[0048] The utility model embodiment provides a flat board support for realizing the temporary fixing and locking of the product with flat board characteristics, such as flat board product, mobile phone product, electronic book product etc. Taking flat board product as an example, as shown in Figure 1 And Figure 2 The utility model provides flat board support including support body 1, first component 2, lock 3 and second component 4, wherein, first component 2 is angularly adjustable and is located on support body 1, and the angularly adjustable range includes but is not limited to any one or more angle adjustable of the pitch angle and the rotation angle relative to support body 1;Lock 3 is located on first component 2, and lock 3 has locking state and unlocking state;Second component 4 is fixedly connected with flat board product, and second component 4 is provided with locking portion 411 matched with lock 3;In locking state, second component 4 is installed to first component 2, and lock 3 locks second component 4 on first component 2;In unlocking state, second component 4 can be separated from first component 2.

[0049] The tablet holder provided by this utility model has a lock 3 on the first component 2 and a tablet product fixedly connected to the second component 4. The tablet product can be installed on the first component 2 through the second component 4. When the second component 4 is installed on the first component 2, the lock 3 on the first component 2 cooperates with the locking part 411 on the second component 4 to lock the second component 4 on the first component 2, thereby locking the tablet product. After locking, the lock 3 needs to be unlocked with a key. After unlocking, the second component 4 and the tablet product need to be removed simultaneously. Compared with the holders in the prior art that directly lock the tablet product, the tablet holder of this utility model does not directly lock the tablet product. By setting the second component 4 to be fixedly connected to the tablet product in advance, the locking and unlocking of the tablet product is transformed into locking and unlocking of the second component 4. This helps to protect the tablet product, avoids damage to the tablet product caused by repeated locking and unlocking, and greatly improves the versatility of the tablet holder. It is suitable for all sizes of tablet products, and is simple to operate, simple in structure, and occupies little space when not in use.

[0050] In some embodiments, the second component 4 includes a locking plate 41, one side of which is fixedly connected to the flat panel product, and a locking part 411 is provided on the locking plate 41.

[0051] like Figure 2 As shown, in this embodiment, the locking plate 41 is a plate with a mounting surface, which facilitates a reliable fixed connection with the tablet product, increases the contact area, and improves the connection strength. In use, the locking plate 41 needs to be fixedly connected to the tablet product first. The fixed connection method can be adhesive bonding or other forms. After the locking plate 41 and the tablet product are fixedly connected, a fixed assembly is formed, which facilitates indirect locking or unlocking of the tablet product, improves the versatility of the tablet holder, and expands its application range. The locking part 411 is configured to cooperate with the lock 3. The locking part 411 can be located on the side of the locking plate 41 opposite to the tablet product, or on the circumferential edge of the locking plate 41.

[0052] In some embodiments, the locking plate 41 is bonded and fixed to the flat product; the locking part 411 includes a locking groove or a locking rod, and the lock 3 cooperates with the locking groove or locking rod to lock or unlock the locking plate 41.

[0053] Specifically, such as Figure 2 As shown, the second component 4 includes a locking plate 41 and an adhesive layer 42. One side of the locking plate 41 is flat and is used to set the adhesive layer 42 to bond and fix the flat panel product. The adhesive layer 42 can be double-sided adhesive, such as nano-adhesive. The adhesive layer 42 is bonded to the surface of the locking plate 41 to bond and fix the flat panel product. The locking part 411 is a mating structure that cooperates with the lock 3 for locking and unlocking, such as... Figure 2As shown, the locking portion 411 is one or more locking slots or holes provided on the side of the lock plate 41 away from the rubber layer 42, which can lock the lock plate 41 when the lock bolt of the lock 3 is inserted into the locking slot or hole. In other embodiments, the locking portion 411 can also be a locking rod, and the lock bolt of the lock 3 correspondingly has a locking hole, and the lock bolt drives the locking hole to be inserted into the locking rod to achieve the effect of locking the lock plate 41. It should be noted that in other optional schemes, when the locking portion 411 is a locking slot or hole, the locking portion 411 can also be provided at any position of the circumferential edge of the lock plate 41. The locking slot and the locking hole can be provided as a long slot or a long hole to facilitate quick positioning and locking with the lock 3.

[0054] For example, as shown in FIG. 1, the lock plate 41 is provided with a plurality of locking portions 411, and the lock 3 is provided with a plurality of locking bolts 31 corresponding to the locking portions 411. The locking portions 411 are provided on the side of the lock plate 41 away from the rubber layer 42, and the locking bolts 31 of the lock 3 are inserted into the locking portions 411 to lock the lock plate 41. Figure 2 For example, as shown in FIG. 1, the lock plate 41 is provided with a plurality of locking portions 411, and the lock 3 is provided with a plurality of locking bolts 31 corresponding to the locking portions 411. The locking portions 411 are provided on the side of the lock plate 41 away from the rubber layer 42, and the locking bolts 31 of the lock 3 are inserted into the locking portions 411 to lock the lock plate 41.

[0055] In some embodiments, the lock plate 41 can be made of a flexible existing material such as a rubber plate, and the lock plate 41 is not completely flexible as a whole, and the rigidity of the lock plate 41 is increased by providing the ribs 412. It is easy to understand that the material of the lock plate 41 is not limited in the utility model, and the recessed portion between the adjacent ribs 412 on the lock plate 41 can easily elastically deform, thereby allowing the lock plate 41 to be torn off from the flat product. When the lock plate 41 is at least partially embeddedly installed on the first assembly 2, it is not easy to make the local deformation of the lock plate 41 at each recess to be torn off.

[0056] In some embodiments, the first assembly 2 includes a mounting plate 21, and the mounting plate 21 is provided with a first limiting portion 212. When the second assembly 4 is installed on the mounting plate 21, the first limiting portion 212 can limit the second assembly 4 from being separated from the first assembly 2 in the first direction (X direction), and the lock 3 can limit the second assembly 4 in the circumferential direction around the first direction to lock.

[0057] Again Figure 2 , the mounting plate 21 is used to mount the lock 3 and the second assembly 4, by setting the first limiting part 212 on the mounting plate 21 and the lock 3, as Figure 3 and Figure 4 , the first limiting part 212 axially limits the second assembly 4, and the lock 3 circumferentially limits the second assembly 4, and the combination of axial and circumferential limiting of the second assembly 4 can simplify the structure of the first assembly 2 and the lock 3, and the locking or unlocking process is easy to operate. Wherein, the first direction (X direction in the middle) can be set as the normal direction of the lock plate 41 or the mounting plate 21, and when the second assembly 4 approaches the first assembly 2 along the normal direction and is installed on the first assembly 2, the first limiting part 212 can limit the second assembly 4 to the first assembly 2 to achieve axial limiting; the lock 3 cooperates with the locking part 411 to limit the circumferential rotation of the second assembly 4, and further to lock the second assembly 4, which is simple in structure, easy to operate and control, and realizes quick locking and unlocking. Figure 4

[0058] For the axial limiting mode of the first limiting part 212, the first embodiment is that the mounting plate 21 is provided with a mounting groove 211, the first limiting part 212 includes a blocking strip circumferentially arranged along the groove wall of the mounting groove 211, the blocking strip and the groove bottom of the mounting groove 211 form a limiting space 213, at least one end of the blocking strip and the groove wall of the mounting groove 211 form an avoiding opening 214, and the circumferential edge of the second assembly 4 is provided with a flange part 413, when the flange part 413 is opposite to the avoiding opening 214, the second assembly 4 can be inserted into the mounting groove 211 along the first direction, and the second assembly 4 can be rotated in the mounting groove 211, so that the flange part 413 is rotated into the limiting space 213 to axially limit the second assembly 4.

[0059] As shown in the embodiment Figure 3 , the surface of the mounting plate 21 is provided with a mounting groove 211 with a circular cross section, the first limiting part 212 is four blocking strips circumferentially arranged along the groove wall at the groove opening of the mounting groove 211, the blocking strips extend a certain distance along the direction perpendicular to the groove wall towards the center of the groove opening of the mounting groove 211, and further form a limiting space 213 between the blocking strips and the groove bottom (as Figure 4 ​), or the avoidance opening 214 is formed between two adjacent blocking strips. Correspondingly, the circumferential edge of the lock plate 41 is provided with four flange portions 413, and the four flange portions 413 are arranged in correspondence with the four avoidance openings 214. During installation, the flange portion 413 is aligned with the avoidance opening 214, and after the lock plate 41 is inserted into the installation groove 211 along the first direction, the lock plate 41 is rotated by a certain angle, so that the flange portion 413 is located in the limiting space 213, the flange portion 413 is located below the blocking strip, and then the lock plate 41 is axially limited in the installation groove 211. The side of the lock plate 41 facing the installation plate 21 is provided with a locking portion 411, and the locking portion 411 includes four lock holes. The lock plate 41 is locked by inserting and cooperating with any one of the lock holes through the lock 3. At this time, the lock 3 can adopt a spring lock. The spring lock is prior art.

[0060] In some embodiments, after the lock plate 41 is inserted into the installation groove 211, the surface of the lock plate 41 provided with the glue layer 42 is flush with the slot of the installation groove 211, that is, after the second assembly 4 is installed, the flat plate product can be in contact with the surface of the installation plate 21 to increase the supporting area of the flat plate product, the structure is more reliable, and the anti-theft effect is achieved. At this time, the side of the flange portion 413 facing the convex rib 412 is flush with the surface of the convex rib 412, and the side of the flange portion 413 facing the glue layer 42 has a spacing distance from the glue layer 42, that is, along the first direction, the thickness of the flange portion 413 is less than the thickness of the lock plate 41, and then when the flange portion 413 is rotated to be limited in the limiting space 213, the surface of the glue layer 42 of the lock plate 41 is flush with the surface of the blocking strip along the first direction, and then the lock plate 41 and the installation plate 21 are precisely fitted and installed.

[0061] For the axial limiting mode of the first limiting portion 212, the second embodiment is as follows:

[0062] The first limiting portion 212 includes an internal thread arranged along the circumferential direction of the groove wall of the installation groove 211, and the second assembly 4 or the flange portion 413 of the second assembly 4 is screwed into the installation groove 211 through the internal thread to axially limit the second assembly 4. In this way, the lock plate 41 and the installation plate 21 are fixed by screwing, the connection mode is more convenient and fast, and the connection is stable and reliable.

[0063] In some embodiments, the groove wall of the installation groove 211 is provided with a second limiting portion 215, and when the second assembly 4 is rotated to abut against the second limiting portion 215, the lock 3 is aligned with the locking portion 411.

[0064] As shown in Figure 3 The second limiting portion 215 can be arranged at any one end of the first limiting portion 212, and when the lock plate 41 is rotated in the installation groove 211, the flange portion 413 can abut against the second limiting portion 215 to stop continuous rotation, at this time, the lock 3 is aligned with the locking portion 411, which is beneficial to the quick locking of the lock plate 41 by the lock 3.

[0065] It is easy to understand that one side surface of the lock plate 41 is connected with the flat plate product, and a plurality of ribs 412 are arranged on the surface of the lock plate 41 away from the flat plate product, and the ribs 412 are arranged in parallel and at intervals, and a groove is formed between two adjacent ribs 412 and penetrates along the length direction of the rib 412. When the lock plate 41 is installed in the mounting groove 211, the operator cannot deform the lock plate 41 in the direction parallel to the width of the rib 412 to tear off from the flat plate product, so it is difficult to separate the lock plate 41 from the flat plate product.

[0066] In some embodiments, the first limiting portion 212 and the second limiting portion 215 form an L-shaped piece, wherein the short side of the L-shaped piece is the second limiting portion 215, the second limiting portion 215 is perpendicular to the groove bottom of the mounting groove 211 and extends from the groove bottom to the groove opening (extends along the X direction), for limiting the rotation angle of the lock plate 41, and has the effect of increasing the structural strength of the mounting groove 211. The long side of the L-shaped piece is the first limiting portion 212, the first limiting portion 212 extends along the circumferential direction of the mounting groove 211 for a certain length, the first limiting portion 212 extends from the groove wall of the mounting groove 211 towards the center of the mounting groove 211 and forms a limiting space 213 with the groove bottom of the mounting groove 211, and along the circumferential direction of the groove wall of the mounting groove 211, one end of the avoiding opening 214 is isolated from the limiting space 213 by the second limiting portion 215. After the lock plate 41 is inserted into the mounting groove 211 and rotated by a certain angle clockwise or counterclockwise, it is axially limited in the limiting space 213, which facilitates the quick positioning of the lock 3 and the locking portion 411 to achieve locking.

[0067] Reference Figure 3 Corresponding to a first limiting portion 212, an avoiding opening 214 is located beside one end of the first limiting portion 212, and a second limiting portion 215 is located beside the other end of the first limiting portion 212.

[0068] In some embodiments, the first assembly 2 further comprises a first connecting arm 22 and a second connecting arm 23, the first connecting arm 22 is fixedly arranged on the bracket body 1, and the first connecting arm 22 is provided with a first shaft 24; the second connecting arm 23 is rotatably arranged on the first shaft 24, and the second connecting arm 23 is provided with a second shaft 25, the second shaft 25 is perpendicular to the first shaft 24, and the mounting plate 21 is rotatably arranged on the second shaft 25.

[0069] As Figure 2 , the first shaft 24 is arranged along the Y direction, the second shaft 25 is arranged along the X direction, the mounting plate 21 can rotate around the second shaft 25, and the rotation angle is freely adjustable; the second connecting arm 23 and the mounting plate 21 can rotate around the first shaft 24 to adjust the pitch angle of the mounting plate 21. As Figure 4The second connecting arm 23 is rotatably installed on the first shaft 24 to realize the rotation connection between the second connecting arm 23 and the first connecting arm 22. The first shaft 24 serves as a pitch shaft, and the pitch movement between the second connecting arm 23 and the first connecting arm 22 can be realized. The pitch shaft is set as a damping shaft, and the pitch angle between the first connecting arm 22 and the second connecting arm 23 can be adjusted arbitrarily. The mounting plate 21 is rotatably installed on the second shaft 25 and can rotate around the second shaft 25 to realize the rotation movement of the mounting plate 21. The second shaft 25 is set as a damping shaft, and the mounting plate 21 can be adjusted at any rotation angle, thereby realizing the arbitrary adjustment of the pitch angle and the rotation angle of the flat product, and facilitating the use.

[0070] In some embodiments, the bottom of the mounting groove 211 is provided with a first mounting hole 216, the first mounting hole 216 is rotatably matched with the second shaft 25, and the first mounting hole 216 can be covered by the second assembly 4 when the second assembly 4 is arranged in the mounting groove 211.

[0071] As shown in Figure 3 and Figure 4 , the bottom of the mounting groove 211 is provided with a first mounting hole 216, the first mounting hole 216 is a through hole, and when the first mounting hole 216 is rotatably sleeved with the second shaft 25, the mounting plate 21 can drive the second assembly 4 and the flat product to rotate around the second shaft 25, thereby realizing the rotation angle adjustment and control of the flat product. By arranging the first mounting hole 216 at the bottom of the mounting groove 211, when the lock plate 41 is installed and locked in the mounting groove 211, the lock plate 41 can cover the first mounting hole 216, and further cover the second shaft 25, thereby realizing the anti-theft effect. Further, the first mounting hole 216 can be arranged on the central axis of the mounting plate 21 or the mounting groove 211. The mounting groove 211 is a circular groove, and the lock plate 41 is a circular plate. The outer diameter (including the flange part 413) of the lock plate 41 is equal to the hole diameter of the mounting groove 211, and the stability of the flat product during rotation is more easily realized.

[0072] In some embodiments, one end of the second shaft 25 is provided with an external thread 251, the other end of the second shaft 25 is provided with a third limiting part 252, one end of the second shaft 25 can pass through the first mounting hole 216 and be threadedly connected to the second connecting arm 23, and the third limiting part 252 directly or indirectly abuts against the mounting plate 21. The mounting plate 21 can rotate around the second shaft 25.

[0073] In combination with Figure 4 and Figure 5One end of the second shaft 25 with external thread 251 passes through the first mounting hole 216 from one side of the bottom of the mounting groove 211 and is threaded to the second connecting arm 23 until the third limiting part 252 directly abuts against the mounting plate 21. The mounting plate 21 is rotatably mounted on the second connecting arm 23. In some embodiments, the first mounting hole 216 is a stepped hole. A first washer 253 and an elastic washer 254 are fitted on the second shaft 25. After the second shaft 25 is installed, the first washer 253 and the elastic washer 254 are sandwiched between the third limiting part 252 and the stepped surface of the stepped hole. The third limiting part 252 indirectly abuts against the mounting plate 21 with the help of the first washer 253 and the elastic washer 254. This allows for damped installation between the mounting plate 21 and the second shaft 25, and the damping can be adjusted by the tightening distance of the second shaft 25, enabling any adjustable rotation angle of the flat plate product. The second shaft 25 can use an anti-theft bolt. A smooth section can be provided between the external thread 251 on the second shaft 25 and the third limiting part 252. The diameters of both the large and small holes of the stepped hole are larger than the outer diameter of the smooth section. After installation, the third limiting part 252 is recessed into the large hole, and the second shaft 25 can only be disassembled by removing the second component 4, thus achieving an anti-theft effect. Figure 5 A second gasket 26 (which can be made of silicone) is provided around the opening of the mounting groove 211. After the second component 4 is installed, the second gasket 26 can be clamped between the locking plate 41 and the mounting plate 21, thereby increasing the friction of the axial installation limit of the locking plate 41 and sealing the mounting groove 211 to minimize relative rotation between the locking plate 41 and the mounting plate 21.

[0074] In some embodiments, the mounting plate 21 is provided with a second mounting hole 217, which communicates with the mounting groove 211 at the bottom or wall of the mounting groove 211. The lock 3 is fixedly disposed in the second mounting hole 217 to lock or unlock the second component 4 installed in the mounting groove 211.

[0075] like Figure 3 As shown, the second mounting hole 217 is located at the bottom of the mounting groove 211, and is spaced apart from the first mounting hole 216. The first mounting hole 216 is located at the center of the mounting groove 211. The lock 3 is screwed into the second mounting hole 217 and fixedly connected. The circumferential rotation of the lock plate 41 is limited by the cooperation of the lock 3 and the locking part 411. In other embodiments, the second mounting hole 217 can also be located on the circumferential edge of the mounting plate 21. In this case, the locking part 411 is located on the circumferential edge of the lock plate 41, which can also achieve circumferential limiting and locking of the lock plate 41.

The two ends of the first shaft 24 are respectively arranged in the two third mounting holes 2211. The second connecting arm 23 is rotatably arranged on the first shaft 24 and clamped between the two side plates 221.

[0077] The two side plates 221 can be respectively fixed on the support body 1 or respectively fixed on the connecting plate 222, and then fixed on the support body 1 through the connecting plate 222. The bottom end of the connecting plate 222 is provided with a plug rod which can be plugged into the top end of the support body 1 for initial installation and positioning. Figure 7 The area between the two side plates 221 of the connecting plate 222 is provided with a counterbore 2221. The third connecting piece 13 is connected to the support body 1 after penetrating the counterbore 2221, thereby achieving detachable connection between the support body 1 and the first connecting arm 22. The third connecting piece 13 can be a bolt, and the third connecting piece 13 is sequentially sleeved with a check ring 132 and a third gasket 131. It should be noted that after the first connecting arm 22 and the second connecting arm 23 are rotatably arranged, the second connecting arm 23 is located above the counterbore 2221. The third connecting piece 13 cannot be detached without detaching the second connecting arm 23, thereby achieving anti-theft installation.

[0078] In some embodiments, the first shaft 24 is a damping shaft, and the first shaft 24 comprises two locking blocks 241 and a first connecting piece 242. The two locking blocks 241 are respectively arranged in the two third mounting holes 2211 in a position-adjustable manner. The first connecting piece 242 penetrates the two locking blocks 241 and the second connecting arm 23 and is locked and fixed by a nut 243, so that the two locking blocks 241 abut against the second connecting arm 23.

[0079] Specifically, the inner wall of the third mounting hole 2211 is provided with a protrusion, and the outer peripheral wall of the locking block 241 is provided with a sliding groove. The two locking blocks 241 are inserted into the two third mounting holes 2211 from the opposite outer sides of the two side plates 221, so that the protrusion is slidingly matched in the sliding groove, thereby achieving circumferential limiting of the locking block 241 and the third mounting hole 2211. Meanwhile, when the first connecting piece 242 and the nut 243 cooperate to lock the two locking blocks 241, the two locking blocks 241 abut against the two ends of the second connecting arm 23 to achieve rotatable installation with damping. By adjusting the rotation distance of the nut 243 on the first connecting piece 242, the abutting force between the two locking blocks 241 and the second connecting arm 23 can be adjusted, thereby achieving adjustment of the damping force. Figure 5 The second connecting arm 23 is T-shaped. Further, the opposite inner sides of the two side plates 221 are respectively provided with fourth gaskets 223. After the second connecting arm 23 is installed, the second connecting arm 23 can be clamped between the two fourth gaskets 223, thereby increasing the friction between the second connecting arm 23 and the side plates 221, which is beneficial to improving the stability of the second connecting arm 23 at any pitch angle.Figure 6 and Figure 7 Two fourth gaskets 223 are provided with insertion parts, and the two fourth gaskets 223 can be respectively inserted and fixed on the two side plates 221, and the second connecting arm 23 has rotating friction with the two fourth gaskets 223 when rotating, so as to reduce the abrasion of the second connecting arm 23 and the side plate 221 and realize damping rotation. In some embodiments, the opposite ends of the two locking blocks 241 are respectively provided with a sunken groove for accommodating the end of the first connecting piece 242 and the nut 243, and the sunken groove can be sealed by the patch 244 after installation, so as to improve the anti-theft effect and improve the aesthetic appearance.

[0080] The convex block on the inner wall of the third mounting hole 2211 and the sliding groove on the outer peripheral wall of the locking block 241 constitute a rotation limiting structure therebetween, which can also be constituted by a key structure, such as a flat key, a spline, etc.

[0081] In some embodiments, one of the locking block 241 and the second connecting arm 23 is provided with an arc-shaped tooth 2411, and the other is provided with an arc-shaped groove 231, the arc-shaped tooth 2411 and the arc-shaped groove 231 are both of a tapered cross section, the tooth height of the arc-shaped tooth 2411 is less than the groove depth of the arc-shaped groove 231, and the arc-shaped tooth 2411 and the arc-shaped groove 231 are inserted and matched.

[0082] As shown in Figure 4 and Figure 5 , the two ends of the second connecting arm 23 on which the locking block 241 is installed are respectively provided with at least one arc-shaped groove 231, and the end of the locking block 241 is provided with an arc-shaped tooth 2411, and when installed, the arc-shaped groove 231 and the arc-shaped tooth 2411 are inserted and matched. Since the arc-shaped tooth 2411 and the arc-shaped groove 231 are both of a tapered cross section, when the arc-shaped tooth 2411 and the arc-shaped groove 231 are inserted and matched, as shown in Figure 7 , the rotation distance of the nut 243 on the first connecting piece 242 is adjusted, the arc-shaped tooth 2411 and the arc-shaped groove 231 are tightly abutted against each other to form a required damping effect, and the damping force can be adjusted. When the second connecting arm 23 is pitch-rotated, the groove wall of the arc-shaped groove 231 and the tooth surface of the arc-shaped tooth 2411 slide relative to each other. It can be understood that the arc of the arc-shaped groove 231 or the arc-shaped tooth 2411 limits the pitch angle of the second connecting arm 23. In order to increase the pitch angle, the arc-shaped groove 231 and / or the arc-shaped tooth 2411 are both of an optimal arc cross section, or a circular ring-shaped groove or a circular ring-shaped tooth is respectively used instead. When the arc-shaped groove 231 and / or the arc-shaped tooth 2411 have a plurality of arc-shaped grooves 231 and a plurality of arc-shaped teeth 2411 respectively, the centers of the plurality of arc-shaped grooves 231 are coaxial, and the centers of the plurality of arc-shaped teeth 2411 are coaxial.
