Description

Technical Field

[0001] This utility model relates to the field of bracket technology, specifically to a computer bracket. Background Technology

[0002] With the continuous improvement of intelligent equipment, highway toll stations are gradually moving towards a booth-less stage to adapt to the trend of efficient and intensive operation. Traditional toll booths are being replaced by smaller, more integrated compact cabinets. These cabinets are usually installed next to the toll lanes or in specific equipment areas, with compact spaces and no fixed operating surfaces nearby. In daily operation and maintenance, maintenance personnel need to regularly maintain and debug the toll system modules, communication modules, power supply modules, and other equipment in the cabinets. This process requires the use of laptops for program debugging and data reading, combined with keyboard input and precise mouse operation. At the same time, they also need to receive work instructions, consult equipment parameter manuals, or communicate with back-end technical personnel via mobile phones.

[0003] However, due to the current lack of a suitable operating platform, maintenance personnel can only use various temporary methods to place equipment: when working beside the driveway, laptops are often placed on the knees or the ground. Knee support can cause the equipment to wobble, affecting operational accuracy, while ground placement makes the equipment susceptible to dust, moisture, and even damage from mud splashed by passing vehicles. When maintaining equipment in a room, although the space is relatively enclosed, the narrow spacing between cabinets forces personnel to hold the laptop and keyboard in their arms. Maintaining this posture for extended periods not only causes arm pain and back strain, significantly increasing labor intensity, but also leads to operational errors due to insufficient hand stability, such as accidentally pressing adjustment buttons and causing system malfunctions, or hardware damage due to accidental slippage. Furthermore, temporary placement methods result in scattered equipment placement, with laptops, keyboards, mice, and mobile phones interfering with each other, reducing maintenance and debugging efficiency, and in severe cases, even delaying troubleshooting progress and affecting normal highway traffic flow, failing to meet the actual needs of maintenance work for convenience, safety, and efficiency. Therefore, there is an urgent need for a support that can provide maintenance personnel with a stable and adjustable operating platform to solve the many problems existing in the above-mentioned technologies. Utility Model Content

[0004] The purpose of this utility model is to provide a computer stand to solve the problem mentioned in the background art of the lack of a suitable operating platform for maintenance personnel to maintain and debug equipment after the elimination of toll booths at highways.

Detailed Implementation

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figure 1-6 As shown, a computer stand includes a support tube 1, a triangular bracket 5 is slidably sleeved on the outside of the support tube 1, the triangular bracket 5 is positioned and connected to the support tube 1 by a first locking rod 4, the legs of the triangular bracket 5 are connected to the bottom of the support tube 1 by a connecting plate 2, and both ends of the connecting plate 2 are rotatably connected to the connected structural components.

[0032] The top of the support tube 1 is connected to a connecting sleeve 6, and the connecting sleeve 6 is connected to a lifting tube 15 that is movably inserted into the support tube 1. The lifting tube 15 has multiple sets of positioning holes 16 that are distributed vertically and pass through the lifting tube 15. The connecting sleeve 6 is positioned and connected to the lifting tube 15 by a second locking rod 7. The top of the connecting sleeve 6 is supported and connected to an insert rod 9 that passes through a set of positioning holes 16. The outer side of the lifting tube 15 is detachably connected to a small tray 11, and the top of the lifting tube 15 is detachably connected to a large tray 20. The large tray 20 is detachably connected to a mobile phone holder 22.

[0033] Support tube 1, connecting plate 2, triangular bracket 5, small tray 11, lifting tube 15, and large tray 20 are all made of metal. The advantages of this setup are: metal materials possess high strength, high hardness, and excellent load-bearing capacity, stably supporting the weight of maintenance equipment such as laptops, keyboards, and mice, preventing deformation or breakage of the bracket during use; simultaneously, metal products are wear-resistant and corrosion-resistant, adapting to complex environments such as open-air lanes at highway toll stations and equipment rooms, extending the overall service life of the bracket and reducing maintenance and replacement costs.

[0034] The bottom of the legs of the tripod bracket 5 is fitted with anti-slip sleeves 3. The advantages of the above-mentioned setting are: the anti-slip sleeves 3 are mostly made of rubber and other anti-slip materials, which can greatly increase the friction between the legs of the tripod bracket 5 and the ground, and prevent the bracket from sliding on cement ground next to the driveway, tile / epoxy resin floor in the equipment room, etc., due to collisions during maintenance personnel operation, shifts in the center of gravity when the equipment is placed, or slight vibrations; at the same time, the anti-slip sleeves 3 can buffer the impact of the legs contacting the ground, reduce the scratch damage to the ground when the bracket is moved, and also reduce the wear of the legs caused by uneven ground.

[0035] The second locking rod 7 is fitted with a collar 8, which is connected to the insertion rod 9 via a connecting rope 10. The advantages of this setup are: by linking the insertion rod 9 to the second locking rod 7 via the connecting rope 10, the insertion rod 9 can be effectively prevented from being lost when disassembling and adjusting the height of the lifting pipe 15—maintenance personnel do not need to separately store the insertion rod 9 when moving between different cabinets in the toll station, reducing the risk of losing small parts; the collar 8 can rotate flexibly around the second locking rod 7 without affecting the twisting operation of the second locking rod 7, while ensuring that the connecting rope 10 always moves synchronously with the second locking rod 7, preventing the rope from becoming tangled or falling off.

[0036] A movable clamp 12 is connected to the corresponding side of the small tray 11 and the lifting tube 15. The movable clamp 12 clamps the lifting tube 15, and a third locking rod 14 is threaded into the clamping opening of the movable clamp 12. The movable clamp 12 is positioned and connected to the lifting tube 15 through the third locking rod 14. The advantages of the above configuration are: the clamping design of the movable clamp 12 allows the small tray 11 to be quickly installed at any height position on the lifting tube 15, adapting to the different mouse operation height requirements of maintenance personnel; the threaded connection structure of the third locking rod 14 allows the clamping tightness to be adjusted by turning, ensuring that the small tray 11 does not loosen after being fixed, and facilitating disassembly, replacement, or position adjustment. The operation is convenient and requires no additional tools.

[0037] An anti-slip pad 13 is connected to the inner side of the clamping jaw of the movable clamp 12. The advantages of the above setting are: the anti-slip pad 13 can increase the friction between the clamping jaw of the movable clamp 12 and the outer wall of the lifting tube 15, further improving the stability of the small tray 11 after installation, and preventing the small tray 11 from sliding along the lifting tube 15 due to equipment vibration or accidental contact by maintenance personnel; at the same time, the anti-slip pad 13 is made of flexible material, which can buffer the pressure on the metal surface of the lifting tube 15 when the movable clamp 12 clamps, prevent scratches or coating damage caused by the clamping jaw, and protect the appearance and structural integrity of the lifting tube 15.

[0038] A mounting sleeve 17 is fitted onto the top of the lifting tube 15. The mounting sleeve 17 is positioned and connected to the lifting tube 15 via a fourth locking rod 18. A mounting plate 19 is connected to the top of the mounting sleeve 17, and the large tray 20 is connected to the mounting plate 19 via fixing screws. The advantages of the above configuration are: the cooperation between the mounting sleeve 17 and the fourth locking rod 18 allows for quick fixing and disassembly of the mounting plate 19 on the top of the lifting tube 15, facilitating individual maintenance or replacement of the large tray 20; the mounting plate 19 is firmly connected to the large tray 20 via fixing screws, and the connection is convenient for disassembly. It can also accommodate large trays of different sizes, improving the versatility of the stand and meeting the placement needs of laptops of different sizes.

[0039] The large tray 20 has multiple evenly distributed heat dissipation slots 21. The advantages of this design are as follows: When maintenance personnel use a laptop to debug the equipment, the computer is prone to generating heat during long-term operation. The heat dissipation slots 21 allow air to circulate up and down on the large tray 20, quickly dissipating the heat from the bottom of the laptop and preventing the computer from freezing, crashing, or being damaged by poor heat dissipation, thus ensuring the continuous and stable progress of maintenance and debugging work. At the same time, the heat dissipation slots 21 can reduce the overall weight of the large tray 20, reduce the difficulty of carrying the bracket while ensuring structural strength, and also prevent water accumulation on the tray surface, reducing the risk of the equipment getting damp.

[0040] The phone holder 22 includes a holder clip 221 that clamps onto the large tray 20. The top of the holder clip 221 is connected to the phone clip 223 via a plastic connecting rod 222. The advantages of this configuration are: the clamping design of the holder clip 221 allows the phone holder 22 to be flexibly installed at any edge of the large tray 20 without occupying computer placement space, and the position can be easily adjusted according to the maintenance personnel's viewing angle; the plastic connecting rod 222 can be bent and shaped arbitrarily, allowing the phone clip 223 to be adjusted to the optimal viewing angle, while also being fixed at any height, avoiding inconvenience caused by the maintenance personnel holding the phone; the phone clip 223 can securely hold phones of different sizes, adapting to different devices used by maintenance personnel and meeting the needs of multiple scenarios such as receiving instructions and consulting manuals.

[0041] Working principle

[0042] I. Principles of Support Deployment and Fixation

[0043] Triangular bracket deployment: Before use, maintenance personnel should first push the triangular bracket 5 to slide along the outside of the support tube 1. At the same time, using the rotational characteristics of both ends of the connecting plate 2, the three legs of the triangular bracket 5 should be deployed outward until the triangular bracket 5 is in a stable supporting state. At this time, rotate the first locking rod 4 so that the end of the first locking rod 4 abuts against the outer wall of the support tube 1, thereby fixing the triangular bracket 5 to the support tube 1 and preventing the triangular bracket 5 from sliding during use.

[0044] Anti-slip and stable: The anti-slip sleeves 3 fitted at the bottom of the five legs of the tripod are in contact with the ground. The rubber material of the anti-slip sleeves 3 increases the friction with the ground, preventing the tripod from sliding due to force during maintenance operations and ensuring the overall stability of the tripod.

[0045] II. Height Adjustment Principle

[0046] Lifting pipe height adjustment and anti-rotation positioning: When adjusting the overall height of the support according to the height and operating habits of the maintenance personnel, first loosen the second locking rod 7 to release its resistance to the lifting pipe 15. Then, pull the lifting pipe 15 up and down along the connecting sleeve 6 at the top of the support pipe 1 until the lifting pipe 15 reaches the appropriate height. At this time, tighten the second locking rod 7 so that the end of the second locking rod 7 abuts against the outer wall of the lifting pipe 15. The abutting force restricts the lifting pipe 15 from rotating around its own axis, ensuring that the lifting pipe 15 maintains a stable posture during subsequent operations and preventing the equipment on the tray from shifting due to rotation.

[0047] Lifting tube load-bearing positioning: After the lifting tube 15 is adjusted to the correct height and prevented from rotating by the second locking rod 7, the insert rod 9 connected to the connecting rope 10 is sleeved onto the second locking rod 7 to prevent the insert rod 9 from being lost and inserted into the positioning hole 16 at the corresponding height of the lifting tube 15. At the same time, both ends of the insert rod 9 are supported by the top of the connecting sleeve 6. Through the cooperation between the insert rod 9 and the positioning hole 16, and the load-bearing effect of the insert rod 9 on the top of the connecting sleeve 6, vertical support and positioning are provided for the lifting tube 15, ensuring that the lifting tube 15 can stably support the weight of the large tray 20, laptop computer and other equipment, and will not sink or shake due to force.

[0048] III. Installation and Usage Principles of Small Trays

[0049] Small tray position adjustment and fixing: The small tray 11 is connected to the lifting tube 15 via the movable clamp 12. During installation, the movable clamp 12 is clamped at a suitable position on the outside of the lifting tube 15. The third locking rod 14 is rotated to retract the clamping jaws of the movable clamp 12 and clamp the lifting tube 15. The anti-slip pad 13 on the inside of the clamping jaws of the movable clamp 12 can increase the friction with the lifting tube 15, prevent the small tray 11 from sliding, and at the same time avoid the movable clamp 12 from causing wear on the surface of the lifting tube 15.

[0050] Functionality: The small tray 11 is used to place the mouse. Its position can be flexibly adjusted according to the operating habits of maintenance personnel, making it convenient for maintenance personnel to perform mouse operations simultaneously while using a laptop, thus improving operational convenience.

[0051] IV. Large Tray Installation and Heat Dissipation Principle

[0052] Large tray installation and fixing: The large tray 20 is connected to the lifting pipe 15 via the mounting plate 19. First, the mounting sleeve 17 is fitted onto the top of the lifting pipe 15. The fourth locking rod 18 is rotated to fix the mounting sleeve 17 to the lifting pipe 15. Then, the large tray 20 is installed on the mounting plate 19 using the fixing screws, thus fixing the large tray 20. If the large tray 20 needs to be replaced, simply remove the fixing screws.

[0053] Heat dissipation function: Multiple evenly distributed heat dissipation slots 21 on the large tray 20 allow the bottom of the laptop to fully contact the air. During the operation of the laptop, heat is quickly dissipated through the heat dissipation slots 21, preventing the laptop from being affected by excessive temperature and ensuring the continuous and stable progress of maintenance and debugging work.

[0054] V. Principles of Mobile Phone Stand Installation and Angle Adjustment

[0055] Phone holder installation and fixation: The phone holder 22 is clamped at a suitable position on the edge of the large tray 20 by the holder clip 221, so as to realize the quick installation and removal of the phone holder 22, and the position of the holder clip 221 on the large tray 20 can be adjusted as needed.

[0056] Angle and height adjustment: The plastic connecting rod 222 at the top of the bracket clamp 221 can be bent and shaped at will. Maintenance personnel can adjust the height and angle of the mobile phone clamp 223 by bending the plastic connecting rod 222. After fixing the mobile phone in the mobile phone clamp 223, it is convenient to view the mobile phone information and meet the needs of multi-device collaborative operation.
