Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically, to a screen fixing device and a computing device. Background Technology

[0002] Currently, screens are typically fixed directly into a matching frame during installation. However, over time, this fit can loosen, easily leading to screen separation, falling, and damage. Furthermore, because the screen and frame are sized together, screen replacement requires consideration of frame compatibility. Generally, the same frame is only suitable for one screen size, resulting in poor compatibility.

[0003] In summary, how to provide a screen fixing device that can improve the reliability of screen installation and is applicable to screens of various sizes is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] The core of this invention is to provide a screen fixing device that fixes the screen to the mounting frame through a fastening mechanism, thereby improving the reliability of screen installation and being applicable to screens of various sizes.

[0062] Another core aspect of this invention is to provide a computing device that includes the aforementioned screen fixing device.

[0063] Please refer to Figure 1 This specific embodiment discloses a screen fixing device, including a mounting frame 1 and at least one fastening mechanism 2. The mounting frame 1 is used to accommodate a screen 3. The fastening mechanism 2 includes a moving component and a locking component. The locking component is mounted on the mounting frame 1 and connected to the moving component. The moving component is movably disposed within the mounting frame 1 to press against and fix the screen 3. The locking component is used to fix and lock the moving component relative to the mounting frame 1, and the moving component can be fixed to at least two different positions relative to the mounting frame 1.

[0064] It should be noted that the moving component in this specific embodiment can move along a straight line or along a curve, depending on the actual situation, which will not be elaborated here.

[0065] When using the screen fixing device provided in this specific embodiment, when installing the screen 3, first place the screen 3 in a suitable position within the mounting frame 1, then move the moving component to a position where the screen 3 can be pressed against it, and lock the moving component with the locking component to fix the screen 3 within the mounting frame 1; when it is necessary to remove the screen 3, release the locking component from the moving component and move the moving component to a position where the screen 3 can be released, and then the screen 3 can be removed from the mounting frame 1; when the size of the screen 3 changes, the moving component can be locked to different positions by the locking component to achieve fixing of screens 3 of different sizes.

[0066] The screen 3 mentioned in this specific embodiment can be a touch screen or a regular screen used for display, depending on the actual situation, which will not be elaborated here.

[0067] The screen fixing device provided in this specific embodiment is locked and fixed to the mounting frame 1 by the fastening mechanism 2, which can effectively improve the installation reliability. In addition, the locking component can lock and fix the moving component to different positions. The same mounting frame 1 can be used for the installation of screens 3 of various sizes.

[0068] In one specific embodiment, the screen 3 is a rectangular structure, the mounting frame 1 is a rectangular structure, and four fastening mechanisms 2 are provided. The four fastening mechanisms 2 are respectively provided on the four sides of the mounting frame 1, and the screen 3 can be clamped and fixed from four directions.

[0069] It should be noted that when there are four fastening mechanisms 2, in order to avoid interference between the movement of adjacent fastening mechanisms 2, the size of the moving components can be appropriately reduced to avoid interference. The specific size can be determined according to the actual situation, which will not be elaborated here.

[0070] In practical use, the fixed position of the screen 3 can be adjusted by adjusting the position of the moving components in different fastening mechanisms 2. Specifically, two of the four fastening mechanisms 2 can be symmetrically set about the middle section of the horizontal direction of the mounting frame 1, and the other two fastening mechanisms 2 can be symmetrically set about the middle section of the vertical direction of the mounting frame 1. By adjusting the position of the moving components in the fastening mechanisms 2, the moving components in the four fastening mechanisms 2 can be made to contact the four outer sides of the screen 3 in the circumference, and the locking components can be adjusted to fix the corresponding moving components and clamp the screen 3.

[0071] When the length of screen 3 changes, the positions of the moving components in the two fastening mechanisms 2 that are set opposite each other in the length direction can be adjusted accordingly to adapt to screen 3 of different lengths; when the height of screen 3 changes, the positions of the moving components in the two fastening mechanisms 2 that are set opposite each other in the height direction can be adjusted accordingly to adapt to screen 3 of different heights.

[0072] In this specific embodiment, four fastening mechanisms 2 are provided, which can clamp the screen 3 from different directions during actual use and can adapt to screens 3 of different lengths and heights. The four fastening mechanisms 2 clamp the screen 3 in the length direction and the height direction respectively, which can further improve the stability of the screen 3 and prevent the screen 3 from being displaced under the action of external force.

[0073] In one specific embodiment, the screen 3 is a rectangular structure, the mounting frame 1 is a rectangular structure, and two fastening mechanisms 2 are provided. The two fastening mechanisms 2 are respectively provided on two opposite sides of the mounting frame 1, which can clamp and fix the screen 3 in the length direction or the height direction.

[0074] In practical use, the fixed position of the screen 3 can be adjusted by adjusting the position of the moving components in different fastening mechanisms 2. Specifically, for example... Figure 1 , Figure 2 As shown, the two fastening mechanisms 2 can be symmetrically arranged about the middle section of the vertical direction of the mounting frame 1. By adjusting the position of the moving components in the fastening mechanism 2, the moving components in the two fastening mechanisms 2 can be made to contact the two opposite outer surfaces of the screen 3 in the circumferential direction. The locking components can be adjusted to fix the corresponding moving components and clamp the screen 3.

[0075] When the length of screen 3 changes, the positions of the moving components in the two fastening mechanisms 2 that are set opposite each other in the length direction can be adjusted accordingly to adapt to screens 3 of different lengths; when the height of screen 3 changes, if the height of screen 3 is less than the height dimension inside the mounting frame 1, then screen 3 can be installed.

[0076] In this specific embodiment, two fastening mechanisms 2 are provided. During actual use, the screen 3 can be clamped on opposite sides of the screen 3, and can adapt to screens 3 of different lengths or heights; thus improving the stability of the screen 3 and preventing the screen 3 from shifting under the action of external forces.

[0077] It should be noted that the height direction of screen 3 and the height direction of mounting frame 1 mentioned in this application document are both... Figure 3 The height direction at the angle shown.

[0078] In one specific embodiment, a fastening mechanism 2 is provided, in which a movable component is movable within the mounting frame 1 and can press the screen 3 against a certain inner side of the mounting frame 1 to fix the screen 3.

[0079] In practical use, the position of the moving component in the fastening mechanism 2 can be adjusted to adapt to screens 3 of different sizes. By adjusting the position of the moving component in the fastening mechanism 2, the moving component in the fastening mechanism 2 can be made to contact a certain outer side of the screen 3 in the circumference. The locking component can be adjusted to fix the corresponding moving component and press the screen 3 to the inner side of the mounting frame 1.

[0080] When the size of the screen 3 in the clamping direction of the fastening mechanism 2 changes, the position of the moving component in the fastening mechanism 2 can be adjusted accordingly to adapt to screens 3 of different sizes.

[0081] In this specific embodiment, only one fastening mechanism 2 is required to clamp and fix the screen 3 and press the screen 3 against a certain inner side of the mounting frame 1. Compared with fixing the screen 3 only through the mounting frame 1, the fastening reliability of the screen 3 can be effectively improved.

[0082] In one specific embodiment, the screen 3 has a polygonal structure and is provided with two fastening mechanisms 2. The two fastening mechanisms 2 are respectively provided on two sides of the mounting frame 1, and the two fastening mechanisms 2 are not arranged opposite to each other. The two fastening mechanisms 2 clamp the screen 3 in different directions, so that the screen 3 can be clamped in two different clamping directions.

[0083] In practical use, the fixed position of the screen 3 can be adjusted by adjusting the position of the moving components in different fastening mechanisms 2. Specifically, during the clamping process of the screen 3, the screen 3 is first placed in the position to be clamped, and then the position of the moving components in the fastening mechanism 2 is adjusted so that the moving components in the two fastening mechanisms 2 move to the positions that contact the two sides of the screen 3 respectively. The moving components are then locked and fixed by the locking components. The screen 3 is locked and fixed to the mounting frame 1 by the two fastening mechanisms 2, thus realizing the installation and fixation of the screen 3. When it is necessary to disassemble the screen 3, the locking components are released from the locking components, and the moving components are moved away from the screen 3 to release the clamping and fixation of the screen 3, so that the screen 3 can be disassembled.

[0084] When the size of screen 3 changes, the position of the moving components in the two fastening mechanisms 2 can be adjusted accordingly to adapt to different sizes of screen 3.

[0085] In this specific embodiment, two fastening mechanisms 2 are provided. During actual use, the screen 3 can be clamped on both sides of the screen 3 and can adapt to screens 3 of different sizes; thus improving the stability of the screen 3 and preventing the screen 3 from shifting under the action of external forces.

[0086] On the other hand, the mounting frame 1 in this application can be a triangle, a polygon, or an irregular shape, and the screen 3 can also be a circle, an ellipse, a polygon, an irregular shape, etc., depending on the actual situation, which will not be elaborated here.

[0087] Based on the above embodiments, the movable component can include a clamping member 21 that can move linearly within the mounting frame 1, and the locking component includes a screw 22 that passes through the side wall of the mounting frame 1. The screw 22 is rotatable relative to the side wall of the mounting frame 1 and is fixed in an axial position. The screw 22 is threadedly connected to the clamping member 21, and rotating the screw 22 can drive the clamping member 21 to move within the mounting frame 1.

[0088] In practical use, the position of the clamping member 21 can be adjusted by rotating the screw 22. Since the axial position of the screw 22 is fixed, the clamping member 21 is moved during the rotation of the screw 22. Within the range of movement of the clamping member 21, the clamping member 21 can stay at any position, realizing stepless adjustment.

[0089] In this specific embodiment, the clamping member 21 is moved by the screw 22, so that the clamping member 21 can stay at any position within the movement range, which is suitable for fixing and clamping screens 3 of different sizes.

[0090] On the other hand, the movable component can include a clamping member 21 that can move linearly within the mounting frame 1. The locking member includes at least one snap-fit ​​portion disposed on the mounting frame 1. The clamping member 21 is provided with a slot. When the clamping member 21 moves to the position corresponding to the snap-fit ​​portion, the slot in the clamping member 21 engages with the snap-fit ​​portion to fix the clamping member 21. During the movement of the clamping member 21, the clamping member 21 can be fixed to the position where it engages with the snap-fit ​​portion, but stepless adjustment cannot be achieved. Specifically, it can be applied to fixing screens 3 of various sizes. In this specific embodiment, although it can only adapt to screens 3 of different sizes according to the number of snap-fit ​​portions, the snap-fit ​​engagement method makes the locking of the clamping member 21 more reliable, which can further improve the fixing reliability of the screen 3.

[0091] In addition, the locking component can be set as a power structure such as a motor. By controlling the movement of the motor, the position of the clamping part 21 can be adjusted, which is conducive to achieving automatic control.

[0092] In addition, to allow the clamping member 21 to move smoothly within the mounting frame 1, a sliding groove can be provided within the mounting frame 1, allowing the clamping member 21 to slide within the groove. Specifically, when the mounting frame 1 has a rectangular structure and is equipped with two fastening mechanisms 2, sliding grooves can be provided on opposite sides of the inner side of the mounting frame 1, with the clamping member 21 located within the groove and slidably positioned there. To ensure the clamping member 21 can slide smoothly within the groove, the inner surface of the groove can be made smooth, or a needle roller structure can be provided between the groove and the clamping member 21 to reduce the friction between them.

[0093] In one specific embodiment, such as Figure 5 As shown, the moving assembly also includes an angle adjustment member 215 and an adjustment knob 216 for adjusting the rotation angle of the angle adjustment member 215. The angle adjustment member 215 is rotatably disposed in the clamping member 21 on the side facing the screen 3 and the angle adjustment member 215 is fixed in an axial position relative to the clamping member 21. The angle adjustment member 215 is used to contact the screen 3 and clamp the screen 3.

[0094] In actual use, rotating the adjustment knob 216 can drive the angle adjustment component 215 to rotate relative to the clamping component 21, thereby driving the screen 3 to rotate relative to the clamping component 21 so that the tilt angle of the screen 3 meets the usage requirements.

[0095] During the clamping process of screen 3, screen 3 is not clamped directly by clamping member 21, but by angle adjustment member 215 directly contacting and clamping screen 3.

[0096] Specifically, during the rotation of the angle adjustment component 215 relative to the clamping component 21, the angle adjustment component 215 can stop and be fixed at any angle position. Specifically, a certain damping can be set so that the angle adjustment component 215 needs to overcome the damping force when rotating relative to the clamping component 21, so as to prevent the screen 3 from rotating unexpectedly under the action of a small external force.

[0097] In this specific embodiment, the screen 3 can be adjusted in angle as needed during use to accommodate operators of different heights and positions.

[0098] In one specific embodiment, the moving assembly further includes a support plate 23, a nut 25 fixed to the support plate 23, and at least one limiting plate 24 parallel to and spaced apart from the support plate 23; the support plate 23 is disposed on the clamping member 21 and is movable along the axial direction of the screw 22, and the limiting plate 24 is fixed to the clamping member 21; the clamping member 21 is provided with a limiting groove 261 for limiting the moving distance of the support plate 23, the screw 22 passes through the limiting plate 24 and the support plate 23 and is threadedly connected to the nut 25, the limiting plate 24 and the support plate 23 are used to limit the radial deformation or displacement of the screw 22, and the limiting plate 24 is fixed to the clamping member 21.

[0099] like Figure 3 As shown, specifically, a first sidewall 211, a second sidewall 212, a third sidewall 213, and a fourth sidewall 214 can be provided on the inner side of the clamping member 21. The length directions of the first sidewall 211 and the second sidewall 212 are arranged along the axial direction perpendicular to the screw 22. The length directions of the third sidewall 213 and the fourth sidewall 214 are arranged along the axial direction of the screw 22 and are respectively located at both ends of the first sidewall 211 and the second sidewall 212, so that the first sidewall 211, the second sidewall 212, the third sidewall 213, and the fourth sidewall 214 enclose a rectangle. A first mounting member 26 is provided on the inner side of the third sidewall 213, and a second mounting member 27 is provided on the inner side of the fourth sidewall 214. The limiting groove 261 includes a first limiting groove provided in the first mounting member 26 and a second limiting groove provided in the second mounting member 27. The first limiting groove and the second limiting groove are arranged opposite to each other, and both ends of the support plate 23 are located in the first limiting groove and the second limiting groove, respectively.

[0100] The inner side of the clamping member 21 mentioned in this application is the side of the clamping member 21 facing the computing device. In this specific embodiment, the first sidewall 211, the second sidewall 212, the third sidewall 213 and the fourth sidewall 214 are all disposed on the inner side of the clamping member 21. The clamping member 21 is a plate-shaped structure. The first sidewall 211, the second sidewall 212, the third sidewall 213 and the fourth sidewall 214 are protruding along the edge of the clamping member 21. The support plate 23, the limiting plate 24, the first mounting member 26 and the second mounting member 27 are all disposed on the inner side of the clamping member 21.

[0101] Specifically, the first sidewall 211, the second sidewall 212, the third sidewall 213, the fourth sidewall 214 and the clamping member 21 can be set as an integral structure.

[0102] like Figure 3 As shown, the dimensions of the first limiting groove in the axial direction of the screw 22 and the second limiting groove in the axial direction of the screw 22 are both larger than the dimensions of the support plate 23 in the axial direction of the screw 22, so that the support plate 23 can be smoothly installed into the limiting groove 261.

[0103] In practical use, the screw 22 passes through the side wall of the mounting frame 1, the first side wall 211, and the support plate 23, and is threadedly connected to the nut 25. The nut 25 is fixedly set on the support plate 23. Rotating the screw 22 will cause the support plate 23 to move axially along the screw 22 within the limiting groove 261. When it is necessary to clamp the screen 3, rotating the screw 22 will move the support plate 23 towards the second side wall 212 until the support plate 23 is in contact with the end of the limiting groove 261 near the second side wall 212. Continuing to rotate the screw 22 can drive the clamping part 2. Move the screw 22 away from the side wall of the mounting frame 1 until the clamping member 21 clamps the screen 3, then stop rotating the screw 22. When it is necessary to release the clamping of the screen 3, rotate the screw 22 in the opposite direction. The screw 22 will drive the support plate 23 away from the second side wall 212 until the support plate 23 is in contact with one end of the first side wall 211 of the limiting groove 261. Continue to rotate the screw 22, which will drive the clamping member 21 to move closer to the side wall of the mounting frame 1 until the clamping member 21 releases the clamping of the screen 3. Stop rotating the screw 22, and the screen 3 can be removed.

[0104] Based on the above embodiments, in order to prevent the screw 22 from rotating unexpectedly under the action of external force when locking the clamping member 21, a locking nut 25 can be set at the end of the screw 22 that extends out of the mounting frame 1 to prevent the screw 22 from rotating unexpectedly. Alternatively, two parallel screws 22 can be set, and after the two screws 22 lock the same clamping member 21, a connecting structure can be used to fix the two parallel screws 22 together. Of course, other methods are also possible, depending on the actual situation, and will not be elaborated here.

[0105] In this specific embodiment, the support plate 23 can provide a certain support for the screw 22. Specifically, a support through hole can be provided in the support plate 23 for the screw 22 to pass through. The support through hole cooperates with the screw 22 so that the screw 22 can only rotate within the support through hole, so as to avoid the screw 22 from bending and deforming when the stroke of the clamping member 21 is long and the axial dimension of the screw 22 is long.

[0106] The support plate 23 can be a metal structure or other materials that meet the requirements, depending on the actual situation, which will not be elaborated here.

[0107] Based on the above embodiments, such as Figure 3As shown, a limiting plate 24 is provided on one side of the support plate 23. One end of the limiting plate 24 is fixedly connected to the first mounting member 26, and the other end is fixedly connected to the second mounting member 27. The limiting plate 24 is provided with a support through hole for the screw 22 to pass through. The support through hole cooperates with the screw 22, so that the screw 22 can only rotate within the support through hole, thereby preventing the screw 22 from bending and deforming when the stroke of the clamping member 21 is long or the axial dimension of the screw 22 is long. The setting of the limiting plate 24 can further improve the support effect of the screw 22 on the basis of the support plate 23, and prevent the screw 22 from bending and deforming or displacing radially.

[0108] Specifically, multiple limiting plates 24 can be set and arranged in parallel with intervals. The limiting plates 24 are parallel to the support plate 23. The limiting plates 24 can be located on one side of the support plate 23, or they can be set on both sides of the support plate 23. The specific location depends on the actual situation and will not be elaborated here.

[0109] On the one hand, a protective gasket 28 can be provided between the outer side of the mounting frame 1 and the screw 22 to prevent the end of the screw 22 from directly contacting the outer side of the mounting frame 1, thereby protecting the outer side of the mounting frame 1.

[0110] The protective gasket 28 can be a metal gasket or other structures that meet the requirements, depending on the actual situation, which will not be elaborated here.

[0111] On the other hand, to avoid pressure damage when the screw 22 presses against the inner wall of the second side wall 212, a first protective member 212a can be provided on the inner side of the second side wall 212. The screw 22 passes through the protective gasket 28, the side wall of the mounting frame 1, and the first side wall 211 in sequence, and can abut against the first protective member 212a on the inner side of the second side wall 212. The first protective member 212a can be a rubber gasket, a sponge gasket, or a metal gasket, depending on the actual situation. The first protective member 212a can be bonded to the inner surface of the second side wall 212, or it can be fixed to the inner surface of the second side wall 212 by other means.

[0112] To prevent the clamping member 21 from damaging the surface of the screen 3 during the clamping process, a second protective member can be provided on the outer side of the clamping member 21 that is in contact with the screen 3. The second protective member can be a rubber pad or a sponge pad, depending on the actual situation, and will not be elaborated here.

[0113] In one specific embodiment, when only two fastening mechanisms 2 are provided, the fastening mechanisms 2 clamp the screen 3 in one direction, such as... Figure 1 , Figure 2As shown, a positioning groove can be provided on the side of the clamping member 21 that contacts the screen 3. During the clamping process, the screen 3 is located in the positioning groove, which can limit the clamping position of the screen 3 in the height direction, thereby improving the clamping positioning accuracy of the screen 3.

[0114] To accommodate screens of different sizes, the positioning groove can be stepped, with multiple recesses of different sizes extending from the bottom to the opening. Figure 1 , Figure 2 When clamped as shown, the smaller screen 3 can be inserted into the recess at the bottom of the positioning groove, while the larger screen 3 can be fitted with the recess near the opening of the positioning groove. Specifically, the depth of the recess needs to be determined according to the actual size of the screen 3, and should not affect the normal use of the screen 3, which will not be elaborated here.

[0115] In one specific embodiment, to better protect the screen 3, the thickness dimension of the mounting frame 1 can be larger than the thickness of the screen 3 to be mounted, so that the screen 3 is completely located within the mounting frame 1 in the thickness direction. In this specific embodiment, the thickness direction of the mounting frame 1 is... Figure 3 The direction shown is perpendicular to the plane of the paper.

[0116] Specifically, the screen 3 can be centered in the thickness direction of the mounting frame 1, and the projection of the screen 3 onto the inner wall of the mounting frame 1 is completely located on the inner wall of the mounting frame 1.

[0117] In this specific embodiment, the mounting frame 1 can completely cover the screen 3 in the thickness direction, preventing external objects from damaging the screen 3 in case of accidents.

[0118] Furthermore, an openable and closable protective cover for protecting the screen 3 can be provided on the surface of the mounting frame 1.

[0119] Specifically, the protective cover can be made of transparent material to facilitate observation of the surface condition of screen 3.

[0120] Alternatively, the protective cover can be rotatably mounted on the mounting frame 1, allowing it to be rotated to an open or closed state. When the protective cover is in the open state, it will not affect the normal use of the screen 3. The protective cover can also be configured as a lift-type structure, which can be raised or lowered to the open state to allow the screen 3 to be used normally, or raised or lowered to the closed state to protect the screen 3.

[0121] In one specific embodiment, the number of fastening mechanisms 2 is at least two, and at least two fastening mechanisms 2 are arranged opposite each other to clamp the screen 3.

[0122] Specifically, the screen 3 can be set as a regular pentagonal structure, and the number of fastening mechanisms 2 is five, corresponding to the five sides of the screen 3 respectively, so as to clamp and fix the screen 3.

[0123] When the screen 3 has an irregular structure, the part of the clamping member 21 that contacts the screen 3 can be set as a contour structure to better fix the screen 3.

[0124] During the rotation of the screw 22 in this application, it is necessary to ensure that the axial position is fixed. In a specific embodiment, a first reinforcement member 29 can be fixed inside the mounting frame 1. A first positioning protrusion is provided at the non-end position of the screw 22, which protrudes radially. The first reinforcement member 29 is provided with a receiving groove 291 for accommodating the first positioning protrusion and a limiting hole 293 located in the receiving groove 291 and penetrating the first reinforcement member 29. One side of the first positioning protrusion is in contact with the inner side of the mounting frame 1, and the other side of the first positioning protrusion is in contact with the bottom surface of the receiving groove 291 to restrict the axial movement of the screw 22.

[0125] Specifically, the portion of the screw 22 located on one side of the first positioning protrusion can engage with the mounting frame 1 and extend out of the mounting frame 1 to engage with the locking nut 25, while the portion of the screw 22 located on the other side of the first positioning protrusion passes through the first reinforcing member 29 and is threadedly connected to the clamping member 21.

[0126] During use, since the first reinforcement member 29 is fixed to the mounting frame 1, the first positioning protrusion is located in the receiving groove 291 between the first reinforcement member 29 and the mounting frame 1. The first reinforcement member 29 cooperates with the mounting frame 1 to limit the axial movement of the screw 22. During the rotation of the screw 22, the screw 22 is fixed in the axial position, which drives the clamping member 21 to move in the axial direction of the screw 22, so as to clamp or release the screen 3.

[0127] On the other hand, during the rotation of the screw 22, friction occurs between the first positioning protrusion and the mounting frame 1, and between the first positioning protrusion and the receiving groove 291. This friction can be minimized by making the surface of the first positioning protrusion, the inner surface of the receiving groove 291, and the inner surface of the mounting frame 1 smooth surfaces; or by installing needle rollers between the first positioning protrusion and the mounting frame 1, and between the first positioning protrusion and the receiving groove 291, to convert sliding friction into rolling friction, thereby minimizing friction. Of course, other methods to reduce friction can also be used, depending on the actual situation, and will not be elaborated here.

[0128] In this specific embodiment, the screw 22 is axially limited by setting a first positioning protrusion at a non-end position of the screw 22 and setting a receiving groove 291 on the first reinforcement 29. The structure is simple and easy to operate.

[0129] Furthermore, a fixing ring 292 can be provided in the receiving groove 291, and a limiting hole 293 is provided in the fixing ring 292. The central axis of the limiting hole 293, the central axis of the fixing ring 292, and the central axis of the receiving groove 291 are all coaxial. The outer wall of the fixing ring 292 and the inner wall of the receiving groove 291 are connected by a connector 294. The connector 294 is arranged radially along the fixing ring 292, and one end of the connector 294 is connected to the inner side of the receiving groove 291, and the other end is connected to the outer side of the fixing ring 292.

[0130] like Figure 4 As shown, the receiving groove 291 is a circular groove, the fixing ring 292 is a circular ring, and the limiting hole 293 is an inner through hole of the fixing ring 292. The fixing ring 292 is connected to the inner side of the receiving groove 291 by a connector 294. There are multiple connectors 294, and the multiple connectors 294 are evenly distributed around the circumference of the fixing ring 292.

[0131] In practical use, the retaining ring 292 is connected to the inner side of the receiving groove 291 via the connector 294. While achieving axial positioning of the screw 22, it can effectively reduce the weight of the first reinforcement 29, which is beneficial to the lightweighting of the device. In addition, by connecting the retaining ring 292 to the inner side of the receiving groove 291 via the connector 294, during the rotation of the screw 22, since the surface of the screw 22 is provided with threads, when the threads come into contact with different positions on the inner side of the retaining ring 292, a radial force will be generated between the threads and the retaining ring 292. This causes the retaining ring 292 to compress a certain connector 294, causing the connector 294 to undergo slight deformation. This can effectively prevent severe wear on the retaining ring 292 during long-term use. At the same time, when the screw 22 undergoes radial deformation or displacement, a radial force is generated between the screw 22 and the retaining ring 292, causing the retaining ring 292 to compress a certain connector 294. This causes the connector 294 to undergo slight deformation, which can effectively protect the screw 22 and prevent damage to the screw 22.

[0132] In this specific embodiment, by setting a fixing ring 292, the screw 22 can be effectively protected, and at the same time, it is beneficial to achieve weight reduction.

[0133] In another specific embodiment, a second reinforcing member is fixed to the inner side of the mounting frame 1. An annular groove is provided at the non-end position of the screw 22. The second reinforcing member is provided with a groove and two positioning members installed in the groove. The positioning members are provided with a second positioning protrusion for engaging with the annular groove. The two positioning members are installed on the outer periphery of the screw 22 by engaging with both sides of the screw 22. When the two positioning members are installed in place, the second positioning protrusion is engaged in the annular groove, and the thickness of the second positioning protrusion is equal to the width of the annular groove to restrict the axial movement of the screw 22 relative to the second reinforcing member. And / or, the protrusion height of the second positioning protrusion is equal to the depth of the annular groove to restrict the radial movement of the screw 22 relative to the second reinforcing member.

[0134] In this specific embodiment, two positioning members are provided and installed on the outer periphery of the screw 22 by the two sides of the screw 22. After the positioning members are placed in the groove, the size of the groove matches the positioning members, which can just limit the positioning members. The positioning members are provided with a semi-circular through hole for the screw 22 to pass through. The inner wall of the semi-circular through hole is provided with a second positioning protrusion, which needs to match the annular groove.

[0135] It should be noted that the second positioning protrusion in this specific embodiment can be a semi-circular protrusion, a rectangular protrusion, or a protrusion of other shapes, as long as the second positioning protrusion can enter the annular groove and cooperate with the annular groove, and the thickness of the second positioning protrusion is equal to the width of the annular groove, the width of the annular groove refers to the dimension of the annular groove in the axial direction of the screw 22.

[0136] In actual use, rotating the screw 22 causes the second positioning protrusion to move within the annular groove, thus limiting the axial position of the screw 22.

[0137] Of course, in this specific embodiment, the number of positioning elements can also be greater than two or other values, depending on the actual situation, which will not be elaborated here.

[0138] Furthermore, during the rotation of the screw 22, there is friction between the annular groove and the second positioning protrusion. To avoid wear on the screw 22 or the second positioning protrusion due to long-term use, which would affect the limiting effect on the screw 22, the surfaces of both the annular groove and the second positioning protrusion can be made smooth to reduce the coefficient of friction and thus reduce the friction force. Alternatively, the hardness of the second positioning protrusion can be made less than that of the screw 22, and the positioning component can be replaced after the second positioning protrusion wears out. Alternatively, needle rollers can be installed between the positioning component and the annular groove to convert sliding friction into rolling friction, thereby reducing the friction force. Of course, other solutions that meet the requirements can also be used, depending on the actual situation, and will not be elaborated here.

[0139] In one specific embodiment, such as Figure 1 , Figure 2As shown, the mounting frame 1 is a rectangular frame, the screen 3 is a rectangular screen 3, and there are two fastening mechanisms 2, which are respectively located on the left and right sides of the mounting frame 1 and are positioned opposite each other. Figure 3 The same fastening mechanism 2 has two parallel screws 22. The screws 22 pass through the side wall of the mounting frame 1, the first reinforcing member 29 or the second reinforcing member, the first side wall 211, the limiting plate 24, and the support plate 23 in sequence, and are threadedly connected to the nuts 25. The two screws 22 in the same fastening mechanism 2 are symmetrically arranged about the middle cross section of the clamping member 21 in the horizontal direction, and the two fastening mechanisms 2 are symmetrically arranged about the middle cross section of the clamping member 21 in the vertical direction.

[0140] In practical use, first place the screen 3 between the two clamping parts 21, and rotate the screw 22 in the fastening mechanism 2 so that... Figure 1 , Figure 2 The screw 22 in the two fastening mechanisms 2 drives the two clamping parts 21 to move closer to each other until the clamping parts 21 clamp and fix the screen 3. When the screen 3 needs to be replaced, the screw 22 needs to be turned in the opposite direction so that the screw 22 in the two fastening mechanisms 2 drives the two clamping parts 21 to move away from each other, release the lock on the screen 3, and remove the screen 3.

[0141] In another specific embodiment, a third reinforcing member can be fixed inside the mounting frame 1. The screw 22 has an annular groove and a third positioning protrusion at its non-end position. The third reinforcing member has a groove and two positioning members installed within the groove. One side of the third positioning protrusion contacts the inner wall of the mounting frame 1, and the other side contacts the groove, thus limiting the axial displacement of the screw 22. The positioning members have a fourth positioning protrusion for engaging with the annular groove. The two positioning members are installed on the outer periphery of the screw 22 by engaging with both sides of the screw 22. When the two positioning members are in place, the fourth positioning protrusion is engaged within the annular groove, and the thickness of the fourth positioning protrusion is equal to the width of the annular groove, thus limiting the axial movement of the screw 22 relative to the third reinforcing member. And / or, the protrusion height of the fourth positioning protrusion is equal to the depth of the annular groove, thus limiting the radial movement of the screw 22 relative to the third reinforcing member.

[0142] During the installation process, the screw 22 can pass through the side wall of the mounting frame 1, the positioning part, and the third reinforcement part in sequence, and the part of the screw 22 extending out of the third reinforcement part is connected to the clamping part 21.

[0143] In this specific embodiment, an annular groove and a third positioning protrusion are provided on the screw 22 to provide double limiting for the axial movement of the screw 22, which can further improve the limiting effect.

[0144] In one specific embodiment, the screen fixing device further includes an elastic element installed on the bottom surface of the mounting frame 1. The elastic element can be a spring or other structure that meets the requirements. When the screen 3 is installed on the mounting frame 1, one end of the elastic element abuts against the bottom surface of the mounting frame 1, and the other end abuts against the moving component. During use, when a large force is applied to the screen 3 unexpectedly, the moving component will compress the elastic element, causing the moving component to move relative to the mounting frame 1. The elastic element deforms, and the screen 3 is displaced, which can effectively protect the screen 3.

[0145] In addition to the screen fixing device described above, the present invention also provides a computing device including a computing device body 4 and the screen fixing device disclosed in the above embodiments, wherein the screen fixing device is disposed on one side of the computing device body 4; the structure of other parts of the computing device is referred to the prior art and will not be described in detail here.

[0146] Specifically, the projection of the screen fixing device onto the main body of the computing device can be completely located inside the computing device, that is, the size of the screen fixing device is smaller than the size of the main body 4 of the computing device at its location, so as to avoid accidental contact with the screen fixing device when external objects move, and better protect the screen 3.

[0147] In one specific embodiment, the mounting frame 1 is fixed to the mounting platform 5 by a fixing rod 7, and the mounting frame 1 is fixedly or movably connected to the fixing rod 7.

[0148] Specifically, the fixing rod 7 can be a fixed rod-shaped structure, such as... Figure 1 , Figure 2 As shown, the mounting frame 1 is fixed to the mounting platform 5 by the fixing rod 7, and the fixing rod 7 provides a fixed support for the screen fixing device.

[0149] On the other hand, the fixing rod 7 can be set as a height-adjustable structure, and the installation height of the screen fixing device can be adjusted by adjusting the fixing rod 7, thereby adjusting the installation height of the screen 3; furthermore, a rotating component can be set on the fixing rod 7, and the mounting frame 1 is mounted on the rotating component, and the installation angle of the screen fixing device can be adjusted by rotating the component.

[0150] Specifically, the rotating component can be a combination of a ball joint structure, a pin shaft, and a mounting base, etc., depending on the actual situation, and will not be elaborated here.

[0151] Furthermore, multiple mounting positions for mounting the fixing rods 7 can be set on the mounting platform 5, and the mounting position of the screen fixing device can be adjusted at any time according to different actual usage conditions.

In the actual setup process, the screen fixing device can also be set on the top of the computing device body 4 or other suitable positions, depending on the actual situation, which will not be elaborated here.

[0153] In one specific embodiment, such as Figure 1 , Figure 2 As shown, the computing device also includes a mounting platform 5 for mounting the computing device body 4 and a base plate 6 disposed on the lower surface of the mounting platform 5. The mounting platform 5 is provided with a dustproof mesh cover 51, and the computing device body 4 is provided with a heat dissipation mesh cover 41 and a protective door 42.

[0154] Specifically, the dust cover 51 can be detachably installed on the mounting platform 5. After the dust cover 51 has been used for a period of time, it can be disassembled and cleaned regularly. When the dust cover 51 is damaged, it can be easily replaced.

[0155] With the protective door 42 open, it facilitates the installation and maintenance of related components. With the protective door 42 closed, it effectively protects the internal structure of the computing device body 4. The heat dissipation mesh cover 41 allows the heat generated by the heat-generating devices inside the computing device body 4 to flow out smoothly and exchange heat with the outside.

[0156] On the one hand, a handle can be installed on the protective door 42 to facilitate opening or closing the protective door 42. Specifically, the protective door 42 can be installed on the main body of the computing device through hinges, or other installation methods can be used, depending on the actual situation, which will not be elaborated here.

[0157] On the other hand, anti-slip pads can be installed on the lower surface of the base plate 6 to make the computing device more stable.

[0158] It should be noted that one or more screen fixing devices can be installed on the same computing device, depending on the actual situation, which will not be elaborated here.

[0159] Based on the above embodiments, such as Figure 1 , Figure 2 As shown, the computing device includes a base plate 6, a mounting platform 5 mounted on the base plate 6, a computing device body 4 disposed on the upper surface of the mounting platform 5, and a screen fixing device disposed on one side of the computing device body 4. In the specific installation process, the fixing rod 7 can be fixedly disposed on the mounting platform 5 at one end and connected to the screen fixing device at the other end; or one end of the fixing rod 7 can be fixedly connected to the computing device body 4 and the other end connected to the screen fixing device. The specific method depends on the actual situation and will not be elaborated here.
