[0029] The following specific implementation manner will further illustrate the present utility model in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] Reference Figure 1-10, a portable computer fixing workbench provided by the utility model comprises a table body 100 and a frame 200, the frame 200 is rotatably arranged on a table surface 110 on one side of the table body 100, and a plurality of positioning support blocks 300 are arranged on the upper side of the frame 200. Exemplarily, the frame 200 is rectangular as a whole, and positioning support blocks 300 are arranged on the left front side, the right front side, the left rear side and the right rear side thereof, wherein the positioning support blocks 300 at the left rear side and the right rear side of the frame 200 are provided with positioning mechanisms 310, and the positioning support blocks 300 at the left front side and the right front side of the frame 200 are provided with first quick-release locking mechanisms 320, and the first quick-release locking mechanisms 320 are used to realize quick locking and unlocking between the frame 200 and the portable computer 400. The frame 200 is provided with a second quick-release locking mechanism 220, and the second quick-release locking mechanism 220 is used to realize quick locking and unlocking between the frame 200 and the table body 100. A circular torque hinge 500 is provided between the shelf 200 and the table body 100. The fixed portion of the circular torque hinge 500 is fixedly connected to the table body 100 by fasteners, and the rotating portion of the circular torque hinge 500 is fixedly connected to the shelf 200 by fasteners. The circular torque hinge 500 can be used to realize the rotation of the shelf 20 relative to the table 110. At the same time, since it has a certain damping, the hand feel when adjusting the angle can be improved. It should be noted that the front, back, left, and right directions of the shelf 200 are based on the user's working position on the workbench.

[0033] It is understandable that the frame 200 as a whole may also present other shapes, and the number and installation positions of the positioning support blocks 300 may be flexibly set. For example, the frame 200 as a whole is still rectangular, and positioning support blocks 300 are provided on the left front side, right front side, left rear side and right rear side thereof, wherein the positioning support blocks 300 at the left rear side and left front side of the frame 200 are provided with positioning mechanisms 310, and the positioning support blocks 300 at the right front side and right rear side of the frame 200 are provided with first quick-release locking mechanisms 320. In addition, the position of the second quick-release locking mechanism 220 may also be flexibly set, for example, set at the left front side or right front side of the frame 200. Considering that the user's hands may pass through the left front side or right front side of the frame 200 when using the portable computer 400, the second quick-release locking mechanism 220 is preferably set in the middle of the front side.

[0034] In this embodiment, when fixing the portable computer 400, the portable computer 400 is first placed on the positioning support block 300, and then positioned by the positioning mechanism 310, and then locked by the hand acting on the first quick release locking mechanism 320, so that the portable computer 400 is firmly fixed on the shelf 200. In order to prevent the shelf 200 from rotating, the hand can act on the second quick release locking mechanism 220 to firmly fix the shelf 200 on the table 110. When the portable computer 400 needs to be taken away, the hand acts on the first quick release locking mechanism 320 to unlock it, and then the positioning mechanism 310 is separated from the portable computer 400. In addition, when the screen of the portable computer 400 fixed on the shelf 200 needs to be directed toward the workstation opposite to the current workstation, the user first acts on the first quick-release locking mechanism 320 to unlock it, then applies force to the shelf 200 to rotate it 180 degrees, and finally acts on the second quick-release locking mechanism 220 to firmly fix the shelf 200 on the table 110. In the above usage scenario, the user does not need to move or leave the workstation, and can quickly complete it by hand, which greatly improves the user experience.

[0035] In some optional embodiments, such as Figure 5 , 6 As shown, a first limiting hole 330 is provided on the positioning support block 300 at the left front side and the right front side of the frame plate 200, and the first quick-release locking mechanism 320 includes a first handle screw 321, a first limiting plate 322, and a second limiting plate 323. The diameter of the rod of the first handle screw 321 is smaller than its threaded portion, and the diameter of the first limiting hole 330 is adapted to the threaded portion of the first handle screw 321, that is, the threaded portion of the first handle screw 321 can smoothly pass through the first limiting hole 330 with less radial shaking, and the first limiting plate 322 and the second limiting plate 323 are fixed to the positioning support block 300 by fasteners. 00 and spliced ​​together, the first limiting plate 322 and the second limiting plate 323 are spliced ​​to form a waist hole 324, that is, the waist hole 324 is in the shape of a long strip, the width of the waist hole 324 is greater than the diameter of the rod of the first handle screw 321, and smaller than the diameter of the threaded portion of the first handle screw 321, the rod of the first handle screw 321 is inserted into the waist hole 324, and the threaded portion of the first handle screw 321 is inserted into the first limiting hole 330 and partially extends out, so that the extended threaded portion can be connected and matched with the threaded hole of the portable computer 400 to achieve the function of fixing the portable computer 400. In order to prevent the fingers from slipping during the process of tightening or loosening the first handle screw 321, the handle of the first handle screw 321 can adopt a rounded four-pointed star and circular knurling design.

[0036] In this embodiment, when assembling the first handle screw 321, first insert the threaded portion of the first handle screw 321 into the first limiting hole 330, and then install and splice the first limiting plate 322 and the second limiting plate 323, so that the rod of the first handle screw 321 is inserted into the waist hole 324. When it is necessary to fix the portable computer 400, the handle on the first handle screw 321 is applied by hand and rotated in a fixed direction until the threaded portion of the first handle screw 321 is connected and matched with the threaded hole of the portable computer 400. When it is not necessary to fix the portable computer 400, the handle on the first handle screw 321 is rotated in the opposite direction. Since the width of the waist hole 324 is larger than the rod diameter of the first handle screw 321 but smaller than the threaded portion diameter of the first handle screw 321, the first handle screw 321 cannot pass through the waist hole 324 and falls out due to the limiting effect of the first limiting plate 322 and the second limiting plate 323. In addition, by providing the waist hole 324, a certain adjustment space can be provided for the installation position of the first handle screw 321 when assembling the first handle screw 321, thereby preventing the problem that the position thereof cannot match the position of the threaded hole of the portable computer 400 due to processing error.

[0037] In some optional embodiments, such as Figure 5 , 7 As shown in FIGS. 8 and 9, the frame plate 200 is provided with a second limiting hole 230, the platform body 100 is provided with a first threaded hole 120 corresponding to the position of the second limiting hole 230, the second quick-release locking mechanism 220 includes a second handle screw 221, a third limiting plate 222, and a fourth limiting plate 223, the rod diameter of the second handle screw 221 is smaller than its threaded portion, the third limiting plate 222 and the fourth limiting plate 223 are both fixedly connected to the frame plate 200 by fasteners, and the third limiting plate 222 and the fourth limiting plate 223 are spliced ​​to form the third limiting hole 6 00, the diameter of the third limiting hole 600 is larger than the diameter of the rod of the second handle screw 221, but smaller than the diameter of the threaded portion of the second handle screw 221, the diameter of the second limiting hole 230 is adapted to the threaded portion of the second handle screw 221, that is, the threaded portion of the second handle screw 221 can smoothly pass through the second limiting hole 230 with less radial shaking, the rod of the second handle screw 221 is inserted into the third limiting hole 600, and the threaded portion of the second handle screw 221 is connected and matched with the first threaded hole 120 after passing through the second limiting hole 230. In order to prevent the fingers from slipping during the process of tightening or loosening the second handle screw 221, the handle of the second handle screw 221 can adopt a rounded four-pointed star and circular knurling design.

[0038] In this embodiment, when assembling the second handle screw 221, first insert the threaded portion of the second handle screw 221 into the second limiting hole 230, and then install and splice the third limiting plate 222 and the fourth limiting plate 223, so that the rod of the second handle screw 221 is inserted into the third limiting hole 600. When the frame plate 200 needs to be fixed, the handle on the second handle screw 221 is applied by hand and rotated in a fixed direction until the threaded portion of the second handle screw 221 is connected and matched with the first threaded hole 120. When the frame plate 200 does not need to be fixed, the handle on the second handle screw 221 is rotated in the opposite direction. Since the diameter of the second limiting hole 230 is larger than the rod diameter of the second handle screw 221 and smaller than the threaded portion diameter of the second handle screw 221, the second handle screw 221 cannot pass through the third limiting hole 600 and fall out due to the limiting effect of the third limiting plate 222 and the fourth limiting plate 223. In addition, by providing the third limiting hole 600, a certain adjustment space can be provided for the installation position of the second handle screw 221 when assembling the second handle screw 221, thereby preventing the problem that the position thereof cannot match the position of the first threaded hole 120 due to processing errors.

[0039] In some optional embodiments, such as Figure 5 , 7 As shown, the second quick-release locking mechanism 220 also includes a spring 224, which is sandwiched between the whole formed by splicing the third limiting plate 222 and the fourth limiting plate 223 and the handle of the second handle screw 221, and the rod of the second handle screw 221 is sleeved in the middle of the spring 224.

[0040] In this embodiment, when there is no need to fix the frame plate 200, the threaded portion of the second handle screw 221 is disengaged from the first threaded hole 120. Under the action of the rebound force of the spring 224, the threaded portion of the second handle screw 221 can always remain disengaged from the first threaded hole 120, that is, it is not released from the table top 110. At this time, there is no need to lift the handle of the second handle screw 221, and the frame plate 200 can also rotate smoothly relative to the table top 110.

[0041] In some optional embodiments, such as Figure 5 , 7 As shown, the third limiting plate 222 and the fourth limiting plate 223 are respectively provided with an annular first groove 2221 and a second groove 2231. After the third limiting plate 222 and the fourth limiting plate 223 are spliced ​​together, the first groove 2221 and the second groove 2231 form a circular groove capable of accommodating the lower end of the spring 224.

[0042] In this embodiment, the circular groove is provided to prevent the spring 224 from being misaligned during assembly, which would reduce the assembly accuracy and affect the use of the second handle screw 221 .

[0043] In some optional embodiments, such as Figure 3 , 4 As shown, the frame plate 200 is provided with a first wiring hole 240, the upper side of the frame plate 200 is provided with a cover plate assembly 700, and the middle part of the cover plate assembly 700 is provided with a second wiring hole 800 corresponding to the position of the first wiring hole 240. During assembly, the fasteners are sequentially passed through the cover plate assembly 700, the frame plate 200 and the rotating part of the circular torque hinge 500, or the fasteners are sequentially passed through the rotating part of the circular torque hinge 500, the frame plate 200 and the cover plate assembly 700, so that the three are tightly fixed together, so that the frame plate 200 can rotate relative to the fixed part of the circular torque hinge 500. In addition, for aesthetics, a mounting groove 111 can be provided on the table 110, and the circular torque hinge 500 is placed in the mounting groove 111, and its fixed part is fixed in the mounting groove 111, so that the bottom of the frame plate 200 is as close to the table 110 as possible, so that the table 110 can provide an upward support force during rotation to prevent the frame plate 200 from being deformed and causing rotation obstruction.

[0044] In this embodiment, since the middle of the circular torque hinge 500 is generally hollow, by providing the first wiring hole 240 and the second wiring hole 800, the function of hidden wiring can be achieved, avoiding cluttered cables that occupy table space and affect the appearance, and at the same time, it is not easy for the rotation of the portable computer 400 to cause damage to the related cables.

[0045] In some optional embodiments, such as Figure 3 , 4 As shown, the cover plate assembly 700 includes a first cover plate 710 and a second cover plate 720, and the first cover plate 710 and the second cover plate 720 are spliced ​​to form a second wiring hole 800. In order to prevent dust, hide ugliness and prevent the cable surface from being scratched, a threading hole cover made of a flexible material, such as a threading hole cover made of a rubber material, can be set in the second wiring hole 800.

[0046] In some optional embodiments, such as Figure 5 As shown, the positioning mechanism 310 includes a positioning pin, one end of which is tapered, so that when it cooperates with the positioning hole on the shell of the portable computer 400, it can play a role in automatically guiding the device to fix the position, and the other end of the positioning pin is passed through the positioning support block 300 at the left rear side and the right rear side of the frame plate 200. At this time, the positioning pin can be fixed on the positioning support block 300 by a nut.

[0047] In some optional embodiments, such as Figure 5-7As shown, a plurality of gaskets 900 are provided between the frame plate 200 and the table body 100. For example, gaskets 900 are provided at the left bottom and right bottom of the frame plate 200 and at the corresponding second quick release locking mechanism 220, so that the gaskets 900 can not only play a supporting role to prevent the frame plate 200 from deforming, but also prevent the bottom of the frame plate 200 from directly contacting the table top 110, thereby reducing the resistance during rotation and not easily causing wear to the paint surface of the table top 110. In order to further reduce the rotation resistance, the gaskets 900 can be processed with nylon material, and the side of the gaskets 900 in contact with the table top 110 is set to a smooth state.

[0048] In some optional embodiments, such as Figure 5 , 6 As shown, the cross-section of the positioning support block 300 is L-shaped. Since the vertical change of the L-shaped positioning support block 300 can prevent the portable computer 400 from moving horizontally, the portable computer 400 can be positioned and fixed more conveniently by reasonably setting the number and layout positions of the positioning support blocks 300.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
