Description

I. Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for conference equipment. Specifically, it is a power cable tray that is applied to conference scenarios and is specially adapted to accommodate the power and signal cables of broadcasting and television equipment such as cameras, microphones, and LED screens, and can effectively prevent people from tripping. II. Background Technology

[0002] In various conference settings, broadcast television equipment requires the temporary installation of a large number of power and signal cables to meet normal operating requirements. Currently, most cable trays on the market are ordinary long plastic trays, which present several problems that urgently need to be addressed in practical applications:

[0003] First, the surface of ordinary cable trays is relatively smooth. When people frequently walk around during meetings, they are prone to tripping and falling if they accidentally step on or come into contact with the cable tray, posing a threat to their safety. Second, the connection between the cable tray cover and the tray body is relatively loose. When people step on it, when equipment is moved, or when other external forces are applied, the cover is very easy to fall off, causing the internal cables to be exposed. This not only affects the cleanliness and aesthetics of the meeting venue but may also damage the cables, thus affecting the normal operation of the broadcasting and television equipment. Finally, ordinary cable trays rely solely on their own weight to rest on the ground, lacking effective fixing measures. When people walk around during meetings or when equipment needs to be moved temporarily, the cable trays are prone to shifting, disrupting the normal cable layout, seriously affecting the stability of the cable power supply, and posing a hidden danger to the reliable operation of the broadcasting and television equipment.

[0004] Given the problems of ordinary cable trays in conference scenarios, there is an urgent need for a power cable tray that is trip-proof, securely fixed, and has a cover that is not easy to fall off, in order to meet the high-frequency needs of temporary wiring in conference scenarios and ensure the smooth operation of conference activities. III. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] The purpose of this utility model is to solve the problems of cable trays used for broadcasting and television equipment in conference settings, which can easily cause people to trip, cable trays to shift, and cover plates to fall off. It provides a simple, easy-to-install, and highly safe anti-tripping power cable tray, thereby optimizing the wiring environment of broadcasting and television equipment at conference sites and ensuring stable equipment operation and personnel safety.

[0007] (II) Technical Solution

[0008] A tripping-proof power cable tray for broadcast television equipment in a conference setting mainly consists of three parts: the cable tray body, the cover plate, and the fixing components. The specific structure of each part is as follows:

[0009] 1.Trunk body

[0010] The cable tray body has a long, rectangular structure and is made of ABS plastic. This material has excellent wear resistance and pressure resistance, and can withstand the external forces such as being stepped on and bumped during temporary use in meeting scenarios, thus extending the service life of the cable tray.

[0011] Inside the cable tray, 2-3 partitions are arranged along its length, dividing the internal space into two independent cavities: a "power cable cavity" and a "signal cable cavity." This partitioning design effectively prevents power and signal cables from tangling within the tray, facilitating subsequent cable inspection and maintenance, reducing interference between different types of cables, and ensuring signal transmission quality and power supply stability.

[0012] On both sides of the upper surface of the cable tray body, there are raised "strips" along the length direction. The cross-sectional shape of the strips is "L" shaped. Their main function is to fasten and connect with the cover plate to ensure that the cover plate can be stably covered on the cable tray body.

[0013] The lower surface of the cable tray body has ground fixing holes at regular intervals. The diameter of the fixing holes is 6-8mm, and the distance between two adjacent fixing holes is 20-30cm. Each fixing hole has an internal thread, which allows the cable tray body to be fixed to a cement floor with expansion screws, or to a wooden floor or carpet floor with self-tapping screws and double-sided tape. This adapts to different floor materials in meeting venues and improves the versatility of the cable tray.

[0014] In addition, the upper surface of the cable tray body is also provided with anti-slip texture. The texture is in the form of horizontal strips with a depth of 1-2mm. The presence of the anti-slip texture can significantly increase the friction between the sole of the shoe and the surface of the cable tray when people step on it, effectively preventing people from slipping and falling, and further improving the safety performance of the cable tray.

[0015] 2. Cover plate snap-fit ​​structure

[0016] The cover plate is a long rectangular plate that matches the shape and size of the cable tray body. Its material is consistent with that of the cable tray body, both of which are made of ABS plastic to ensure the coordination of the cover plate and the cable tray body in terms of physical properties and appearance.

[0017] On both sides of the lower surface of the cover plate, there are "buckles" along its length. The cross-sectional shape of these buckles is a "barb" shape that matches the "L"-shaped retaining strip on the cable tray body. When the cover plate is closed on the cable tray body, the "barb buckles" on the cover plate can tightly engage with the "L"-shaped retaining strip on the cable tray body. Testing shows that opening the closed cover plate from the cable tray body requires a pulling force of 5-10N. This design effectively prevents the cover plate from falling off due to accidental contact or stepping during daily use, ensuring the safe storage of cables within the tray.

[0018] To facilitate the installation and removal of the cover plate by staff, a "handle groove" is provided at one end of the cover plate. The groove is 3-4mm deep and 10-15mm wide. When staff need to open the cover plate, they can easily open it by simply gripping the handle groove with their fingers. The entire process does not require any tools, which can well meet the needs of rapid wiring and emergency maintenance in conference scenarios, improving work efficiency.

[0019] 3. Fixing components

[0020] The fixing components mainly include two parts: expansion screws and double-sided adhesive pads, which are used in conjunction with the product to meet the fixing requirements of different floor materials.

[0021] Expansion bolts: These expansion bolts are designed to fit the dimensions of the fixing holes on the lower surface of the cable tray body. They are primarily used to secure the cable tray body to a concrete floor. In use, the expansion bolts are passed through the fixing holes on the cable tray body and screwed into the concrete floor. The tightening action between the expansion bolts and the floor ensures a secure fixation of the cable tray body.

[0022] Double-sided adhesive pad: The double-sided adhesive pad is circular in shape, and its diameter is consistent with the diameter of the fixing holes on the lower surface of the cable tray body. One side of the double-sided adhesive pad is pre-applied with an adhesive substance and can be directly pasted to the area around the fixing holes on the lower surface of the cable tray body. The other side of the double-sided adhesive pad is covered with a protective film. During use, simply peel off the protective film to paste the cable tray body onto the wooden floor or carpet. The operation is simple and convenient, enabling quick and easy fixation of the cable tray body.

[0023] (III) Working Principle

[0024] Cable tray fixing: When installing the cable trays, first select the appropriate fixing method based on the specific material of the venue floor. If the venue floor is cement, use expansion screws. Pass the expansion screws through the fixing holes on the lower surface of the cable tray body and screw them firmly into the cement floor until the cable tray body is firmly attached to the floor. If the venue floor is wood flooring or carpet, use double-sided adhesive pads. Stick one side of the double-sided adhesive pad around the fixing holes on the lower surface of the cable tray body, peel off the protective film on the other side, and press the cable tray body into the corresponding position on the floor, ensuring that the double-sided adhesive pad is firmly attached to the floor, thus completing the fixing of the cable tray body.

[0025] Cable sorting and storage: The power cords and signal cables required for broadcast and television equipment are sorted and organized, and then placed into the corresponding "power cord cavity" and "signal cord cavity" inside the cable tray. The partition plate is used to prevent the power cords and signal cables from getting tangled, ensuring that the cable layout is neat.

[0026] Cover plate closing operation: Align the cover plate with the upper surface of the cable tray body, so that the "barbed buckles" on both sides of the lower surface of the cover plate correspond to the "L"-shaped clips on both sides of the upper surface of the cable tray body. Then gently press the cover plate down until the "barbed buckles" and "L"-shaped clips are fully engaged, so as to achieve stable closing of the cover plate and complete the storage and protection of the cables.

[0027] Routine Use and Maintenance: During meetings, if someone accidentally steps on the cable tray, the anti-slip texture on the surface of the tray increases the friction between the shoe sole and the tray surface, effectively preventing tripping. When it is necessary to inspect or maintain the cables inside the tray, staff only need to use their fingers to hold the "lifting handle" at one end of the cover and gently lift it upwards to open the cover and perform inspection or repair operations on the cables. The entire process requires no tools, making it convenient and efficient. IV. Description of the attached drawings

V. Detailed Implementation Methods

[0036] To make the technical solution, purpose, and beneficial effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to specific embodiments.

[0037] (I) Example 1: Material preparation for cement floor meeting venue: Prepare a 10-meter-long cable tray body (made of ABS plastic, with a height of 3cm, two partitions inside, a horizontal anti-slip texture with a depth of 1mm on the upper surface, and fixing holes with a diameter of 6mm and a spacing of 20cm on the lower surface, and the fixing holes have internal threads), a 10-meter-long cover plate matching the cable tray body (made of the same material, with barbed buckles on both sides of the lower surface, and a handle groove with a depth of 3mm and a width of 10mm on one end), and a number of matching expansion screws (diameter of 6mm, length determined according to the thickness of the ground).

[0038] Cable tray mounting: Determine the cable tray installation path based on the wiring plan for the broadcast and television equipment at the conference venue. Then, place the cable tray body along the planned path on the cement floor. Use an electric drill to drill holes in the floor at the locations corresponding to the mounting holes of the cable tray body, with the drilling depth matching the length of the expansion bolts. Next, pass the expansion bolts through the mounting holes of the cable tray body and screw them into the pre-drilled holes in the floor, ensuring that each mounting hole is fitted with an expansion bolt and that the cable tray body is firmly attached to the floor without any looseness.

[0039] Cable laying and storage: After tidying up the power cords of broadcasting and television equipment such as cameras and LED screens, put them into the "power cord cavity" of the cable tray body. After tidying up the signal cables of equipment such as microphones, put them into the "signal cord cavity" to ensure that the cables are neatly arranged in the cavity and there is no tangling.

[0040] Cover plate fitting: Align the cover plate with the cable tray body, align the barbed buckle of the cover plate with the L-shaped retaining strip of the cable tray body, and then press the cover plate gradually along the length of the tray body to make the buckle and retaining strip tightly engage, thus completing the cover plate fitting.

[0041] Usage and maintenance: During the event, when people walked on the cable tray, the anti-slip texture on the upper surface effectively prevented slipping and no tripping occurred; when a camera power cable malfunctioned and needed maintenance, the staff could easily open the cover by holding the cover with their fingers and lifting the hand groove, find the faulty power cable for repair, and close the cover again after the repair was completed. The entire maintenance process took less than 5 minutes and was easy to operate.

[0042] (II) Example 2: Application of wooden flooring in conference venues

[0043] Materials required: Prepare an 8-meter-long cable tray body (ABS plastic material, 4cm high, with 3 internal partitions, 1.5mm deep horizontal anti-slip texture on the upper surface, 7mm diameter fixing holes spaced 25cm apart on the lower surface, with internal threads), an 8-meter-long matching cover plate (same material, barbed buckle structure, 3.5mm deep and 12mm wide handle groove), and several 7mm diameter round double-sided adhesive pads (matching the diameter of the fixing holes).

[0044] Fixing the cable tray: Clean the dust and debris from the surface of the wooden floor and determine the installation location of the cable tray according to the wiring requirements. Peel off the protective film from one side of the double-sided adhesive pad and stick it around the fixing holes on the lower surface of the cable tray, ensuring that one double-sided adhesive pad is attached to each fixing hole. Then, peel off the protective film from the other side of the double-sided adhesive pad, accurately place the cable tray in the designated position on the wooden floor, and press firmly on the cable tray to ensure that the double-sided adhesive pad is firmly attached to the wooden floor, thus fixing the cable tray in place. After fixing, the cable tray should not shift.

[0045] Cable storage and cover closing: Place the power cord and signal cable of the broadcast television equipment into the corresponding cavity, close the cover, and make the buckle and the clip engage tightly.

[0046] Actual usage results: During the conference, despite frequent personnel movement, the cable trays did not shift. When it was necessary to adjust the LED screen signal cables later, no tools were needed; the cover could be quickly opened by lifting the handle, and then closed again after adjustment. The whole process was efficient and convenient, and did not affect the normal conduct of the conference.

[0047] As can be seen from the above embodiments, the anti-tripping power cable tray of this utility model can be well adapted to meeting venues with different ground materials. It exhibits excellent performance in terms of anti-tripping, fixed stability and ease of operation, and can meet the needs of temporary wiring for broadcast and television equipment in meeting scenarios.

[0048] VI. Beneficial Effects

[0049] Significantly effective at preventing tripping: The horizontal anti-slip stripes on the upper surface of the cable tray greatly increase the friction when people step on it, effectively preventing people from slipping; at the same time, the height of the cable tray is controlled within the range of 3-5cm, which is lower than that of conventional cable trays, further reducing the risk of people tripping. It is especially suitable for scenarios where people move around densely during meetings, providing strong protection for personnel safety.

[0050] Secure and reliable fixing: This utility model is equipped with two fixing components: expansion screws and double-sided adhesive pads, which are suitable for different types of meeting venue floor materials such as cement floors, wooden floors, and carpet floors. Through appropriate fixing methods, the cable tray body can be firmly fixed to the ground, effectively preventing the cable tray from shifting due to personnel movement or equipment movement during meetings. This ensures the stable and reliable power supply and signal lines of the broadcasting and television equipment, guaranteeing the normal operation of the equipment.

[0051] Convenient and efficient operation: The cover plate adopts a tool-free disassembly and assembly design. Workers can easily open or close the cover plate using the handle groove at one end, without the need for additional tools, greatly simplifying the operation process. Actual testing shows that compared to traditional cable trays, this invention improves the efficiency of cable maintenance by 50%. Furthermore, the internal partition design of the cable tray effectively isolates power lines and signal lines, preventing cables from tangling and making the wiring process more orderly, further improving the efficiency of wiring and subsequent maintenance.

[0052] Simple and practical structure: All components of this utility model adopt a mechanical structure design, without involving high-end components such as precision sensors and complex circuits. This not only reduces the difficulty and cost of manufacturing, but also reduces maintenance problems caused by component failures during later use. The structural design of this cable tray fully considers the actual needs of conference scenarios, has strong practicality, and fully meets the requirements of "practicality and novelty" for utility model patents, enabling its widespread application in various conference scenarios.
