Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for cutting teeth, specifically a protective railing for cutting teeth. Background Technology

[0002] During the cutting of cutting tools, due to the high-speed operation of the equipment and the generation of flying debris, it is usually necessary to install protective railings around the processing area to ensure the safety of operators. Existing protective railings mostly adopt a fixed structure, which has the following drawbacks: firstly, the support structure is not adjustable, making it difficult to adapt to uneven ground; secondly, the connection between the railing sections is rigid, making it impossible to flexibly adjust the angle according to the site layout; and thirdly, disassembly and assembly are inconvenient, hindering temporary placement or storage. Therefore, it is necessary to provide a protective railing that is flexible, adjustable, and easy to assemble and disassemble. Utility Model Content

The limiting groove and the second limiting groove limit the support plate; multiple fixing frames are spliced ​​together by a connecting mechanism, the connecting mechanism including a universal joint, the universal joint having threaded grooves at both ends, a threaded block being connected in the threaded groove, and a connecting block being fixed at the other end of the threaded block, the connecting block being adapted to the connecting grooves on both sides of the fixing frame; after two fixing frames are connected, they are fixed by a fixing mechanism, the fixing mechanism including a threaded cylinder, the threaded cylinder having threaded rods at both ends, and a fixing elbow being fixed at the other end of the threaded rod, the fixing elbow being adapted to the fixing groove on the top of the fixing frame.

[0005] Furthermore, the support plate can extend and retract within the rotating plate, and the support length can be adjusted by inserting the U-shaped pin into different second limiting slots.

[0006] Furthermore, the connecting block is installed and removed through the large hole in the connecting groove.

[0007] Furthermore, the universal joint allows for angle adjustment between the two mounting brackets.

[0008] Furthermore, the threaded cylinder adjusts the extension length of the threaded rod by rotation.

[0009] Furthermore, the base is threadedly connected to the fixing frame, facilitating disassembly and height adjustment.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1 to 8 As shown, this utility model provides a protective railing for the outer perimeter of cutting teeth processing, which is a modular and flexibly configurable safety protection device.

[0015] The core unit of the guardrail is the fixing frame 1. In this embodiment, the fixing frame 1 is preferably a rectangular frame structure welded from square steel pipes. A transparent protective plate 6 is fixed inside by slots or screws. The protective plate 6 can be made of high-strength polycarbonate (PC) sheet, which can block debris from flying and does not affect the observation of the processing. Multiple bases 4 are symmetrically threaded to the bottom of the fixing frame 1. Rubber pads are added to the bottom of these bases 4 to increase friction. By turning the bases 4, the height of a single fixing frame 1 can be finely adjusted to adapt to slightly uneven ground.

[0016] The surface of the fixed frame 1 is symmetrically provided with storage slots 2. Each storage slot 2 is movably connected to a support mechanism 3 through a horizontally arranged pin. In the non-working state, the support mechanism 3 can be completely retracted into the storage slot 2, flush with the side of the fixed frame 1, saving space and facilitating transportation.

[0017] See Figure 2 , Figure 3 and Figure 6 The support mechanism 3 includes a rotating plate 301 that is movably connected to the fixed frame 1 via the aforementioned pin. The rotating plate 301 is hollow inside and houses a retractable support plate 305. The support plate 305 can be a rectangular steel plate, and its extended end is fitted with an anti-slip pad to adapt to soft or hard ground. A first limiting groove 302 is formed through the surface of the rotating plate 301 along its length direction. The groove is an elongated hole. The upper end of the support plate 305, i.e. the part located inside the rotating plate 301, has multiple sets of second limiting grooves 304 spaced apart along its length direction. These grooves can be round holes or square holes.

[0018] When support mechanism 3 needs to be deployed, the operating steps are as follows: Rotate the rotating plate 301 outward around the pin axis. When the bottom end of the support plate 305 contacts the ground and reaches the ideal support state, select a second limiting groove 304 that is aligned with the first limiting groove 302 on the rotating plate 301.

[0019] The U-shaped pin 303 is passed through the first limiting groove 302 and the second limiting groove 304 in sequence. After the U-shaped pin 303 passes through the latter, the support plate 305 and the rotating plate 301 are fixed together to form a stable triangular support structure.

[0020] See Figure 4 , Figure 5 and Figure 8 Multiple fixed frames 1 are spliced ​​together by a connecting mechanism 9. On the left and right sides of the fixed frame 1, a connecting groove 7 is vertically opened. The upper part of the connecting groove 7 is a large circular hole with a large diameter, and the lower part is a vertical sliding groove with a smaller width.

[0021] The connecting mechanism 9 includes a universal joint 901, both ends of which are machined with internal threaded grooves 902. Two threaded blocks 904 are screwed into the threaded grooves 902 at both ends respectively. A connecting block 903 is welded to the other end of each threaded block 904. In this embodiment, the connecting block 903 is preferably cylindrical, with a diameter slightly smaller than the large circular hole at the top of the connecting groove 7, but larger than the width of the lower vertical sliding groove.

[0022] The procedure for assembling the two fixing frames 1 is as follows: Align the connecting groove 7 on the side of one of the fixing brackets 1 with the connecting mechanism 9 that has been installed on the other fixing bracket 1.

[0023] Align the connecting block 903 with the large circular hole at the top of the connecting groove 7 and push it inward as a whole.

[0024] Then slide the entire connecting mechanism 9 downwards, so that the connecting block 903 falls into and gets stuck in the vertical slide groove. At this time, the connecting block 903 is restricted in the slide groove, realizing a quick initial connection and limit.

[0025] Due to the presence of the universal joint 901, the two fixed brackets 1 can freely adjust their included angle within a certain cone angle range, thereby forming various layouts such as straight lines, broken lines, or arcs (e.g., Figure 4 , Figure 5 (As shown).

[0026] See Figure 4 , Figure 5 and Figure 7 After the two fixed frames 1 are connected by the connecting mechanism 9 and the angle is adjusted, the fixing mechanism 8 is used for final reinforcement to prevent them from shaking. A fixing groove 5 is provided on the top frame of the fixed frame 1 for each connection position.

[0027] The fixing mechanism 8 includes a threaded cylinder 801 with internal threads of opposite directions (i.e., left-hand and right-hand) machined at both ends. Two threaded rods 802 are screwed into the threaded cylinder 801 from both ends. The other end of each threaded rod 802 is fixed with a fixing elbow 803 by welding or integral forming. The elbow is L-shaped.

[0028] The operating steps for fixing mechanism 8 are as follows: The rotating threaded cylinder 801, with its threads at both ends in opposite directions, will have its two threaded rods 802 extend or retract synchronously during rotation, thereby adjusting the total length of the fixing mechanism 8.

[0029] The fixed elbows 803 at both ends of the fixed mechanism 8, which have been adjusted to the correct length, are respectively inserted into the fixed grooves 5 at the top of the two adjacent fixed frames 1.

[0030] Continue rotating the threaded cylinder 801 so that the length of the fixing mechanism 8 slightly exceeds the net distance between the two fixing slots 5, thereby generating a pre-tightening force that tightly pulls the two fixing brackets 1 together. This tightening action, combined with the hinge action of the universal joint 901 below, forms a stable "upper pull and lower hinge" structure, ensuring that the guardrail as a whole maintains extremely high stability at any angle.
