Description

Technical Field

[0001] The utility model relates to the technical field of communication manhole security equipment, and specifically relates to a lock mounting bracket structure for a communication manhole cover. Background Technique

[0002] A communication manhole refers to an opening structure for personnel to enter and exit communication equipment for installation, maintenance, and safety inspection. A communication manhole mainly consists of a short cylinder section (or short pipe), a flange, and a manhole cover with a handle.

[0003] When workers go down the well, they often open the manhole cover and directly press the side of the manhole cover with a lock on the ground. Since there is no corresponding lock protection device on the manhole cover, the gravity of the heavy manhole cover is directly applied to the lock, which is easy to damage the lock, affect the service life of the lock, and thus increase the maintenance cost of communication equipment.

[0004] Chinese Patent No. CN218204566U discloses a lock mounting bracket structure for a communication manhole cover, which has the advantages of being convenient for installation and disassembly without the aid of tools such as screwdrivers. However, its structure is complex, large in volume, and heavy in mass, resulting in high manufacturing costs and inconvenience in carrying. At the same time, since its support contact surface is a rigid plane, it cannot match some locks and special-shaped manhole covers, resulting in reduced applicability. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a lock mounting frame structure for a communication manhole cover, including a bracket assembly 1 and a manhole cover body 2. The material of the bracket assembly 1 is rubber with a certain hardness and a certain elasticity. The bracket assembly 1 is integrally cast by an injection molding machine. The bracket assembly 1 includes a top pressing block 101. A fork branch 102 is connected to the periphery of the top pressing block 101. The end of the fork branch 102 is connected to a chassis 103. An auxiliary hole 104 is opened on one side of the chassis 103. The fork branch 102 consists of four pieces and is evenly distributed around the top pressing block 101. The fork branch 102 is circular arc-shaped and bends downward. The lower end of the fork branch 102 is connected to the middle position of the chassis 103. A top nut 3 is installed above the top pressing block 101. A top bolt 4 is threadedly connected above the top nut 3. A circular magnetic sheet 5 is installed below the chassis 103. The bottom surface of the chassis 103 is vertically downward. A blind hole with an inner diameter size the same as the outer diameter size of the circular magnetic sheet 5 is opened below the chassis 103. When the circular magnetic sheet 5 is inserted into this blind hole, strong glue is added. The lower surface of the circular magnetic sheet 5 is flush with the lower surface of the chassis 103. A handle and a lock are installed above the manhole cover body 2. The bracket assembly 1 is installed on the upper surface of the manhole cover body 2 through the circular magnetic sheet 5 and the top pressing block 101 is located above the handle and the lock, so that when the manhole cover body 2 is flipped, the top pressing block 101 can be padded below the handle and the lock. The top bolt 4 is a special bolt made according to actual conditions, which can be an ordinary plum blossom head bolt, or a bolt with a hook or a magnet on the head. The top bolt 4 is used to change the supporting height of the top pressing block 101 or fix it to other external objects. A bottom nut 6 is installed below the auxiliary hole 104. An auxiliary bolt 7 is threadedly connected above the bottom nut 6. The lower part of the auxiliary hole 104 is an inner hexagonal hole and the upper part is a round hole. The bottom nut 6 has the same inner hexagonal size and strong glue is added during installation. The lower surface of the bottom nut 6 is flush with the lower surface of the chassis 103. The auxiliary bolt 7 is a plum blossom head bolt. The auxiliary bolt 7 passes through the round hole above the auxiliary hole 104 and is threadedly connected to the bottom nut 6.

[0024] When in use, the bracket assembly 1 is integrally injection-molded by an injection molding machine. Further, apply some glue around the top nut 3 and then press it into the hexagonal socket in the top of the top pressing block 101. Further, apply some glue around each bottom nut 6 and then press it into the hexagonal socket below each auxiliary hole 104. Further, screw each auxiliary bolt 7 into each bottom nut 6 from above the auxiliary hole 104 but without passing through the bottom. Further, cross-stick two by two the four circular magnetic sheets 5 together, so that the deformation volume of the bracket assembly 1 can be reduced and the circular magnetic sheets 5 can be prevented from sticking to other objects outward. Since it is light in weight and small in volume, it is convenient to carry. When opening the manhole cover on site, if it is found that the lock will be pressed or will swing randomly during the opening process of the manhole cover, fix the bracket assembly 1 above the lock through the four circular magnetic sheets 5 of the mounting frame structure, wherein the circular magnetic sheets 5 are distributed around the lock and the spacing is adjustable. The larger the spacing, the closer the top pressing block 101 is to the lock. The specific installation posture depends on the actual situation, only requiring that the top pressing block 101 is on the top of the lock. Since the material of the top pressing block 101 is rubber and has a certain elasticity, after the manhole cover is opened, the lock has the top pressing block 101 as a cushion block to avoid collision with the ground, so the lock can be protected. Since the bracket assembly 1 is connected to the manhole cover through the circular magnetic sheets 5 with adjustable spacing, and there is also a fork branch 102 with a certain length and deformable between the circular magnetic sheets 5 and the top pressing block 101, even if the size or height of the lock changes or the surface of the manhole cover is arc-shaped, the top pressing block 101 can be successfully installed above the lock to protect it. Among them, the height of the top pressing block 101 supporting the top pressing block 101 can also be changed by changing the length of the top bolt 4. If the manhole cover is not installed on the ground but is installed vertically or inverted, the top bolt 4 can be a structure with a hook or magnet at the top for fixing the opened manhole cover. After use, screw down the auxiliary bolt 7 to forcefully lift the circular magnetic sheets 5 and the manhole cover for disassembly.

[0025] In summary, for the lock mounting frame structure used for the communication manhole cover, since the bracket assembly 1 is an integrally injection-molded rubber part with a slender structure and can be deformed, the bracket assembly 1 has a low manufacturing cost, is light in weight, small in volume and is also convenient to carry. Using the bracket assembly 1 as the main body, it is connected to the manhole cover through the circular magnetic sheets 5 below and the support distance is adjusted by the top bolt 4 above, and the structure is very simple. Connecting the bracket assembly 1 with a certain flexibility to the manhole cover through the circular magnetic sheets 5 can be almost installed above all types of manhole covers. By adjusting the height of supporting the manhole cover or fixing the manhole cover through the top bolt 4, it can be applicable to protecting manhole covers in most cases, so the effect of strong applicability is achieved.

[0026] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
