Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a safety guardrail for milling and boring machining centers. Background Technology

[0002] In the field of machining, milling and boring centers are common precision machining equipment. During the machining process, the cutting tool rotates at high speed and the workpiece moves rapidly, generating dangerous factors such as flying chips, coolant, and potentially broken tools. To ensure the safety of operators, safety barriers are usually installed around milling and boring centers to create a danger zone and prevent people from approaching. However, existing safety guardrails for milling and boring machining centers present numerous inconveniences in terms of assembly. Common assembly methods often employ multiple independent screws, bolts, and other fasteners. During assembly, operators must manually install each fastener one by one into its corresponding position. This is not only cumbersome and time-consuming, but also prone to fasteners falling off or being lost during installation. If a fastener is lost, a suitable replacement must be found, which not only affects the installation progress but may also result in an insufficiently secure assembly of the guardrail, posing a safety hazard. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety guardrail for milling and boring machining centers. In actual use, this guardrail facilitates the splicing of two guardrail pieces. Simply bring the two guardrails close together and then tighten the screws. In addition, the screw part adopts an integrated structure with the guardrail, so there will be no situation where the screw parts are lost.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A safety guardrail for a milling and boring machining center includes a guardrail body. Multiple first connecting blocks are fixedly connected to the left side wall of the guardrail body, and multiple second connecting blocks are fixedly connected to the right side of the guardrail body. Each second connecting block has a rectangular groove on its right side, and a strip-shaped opening at the bottom of each rectangular groove. Each second connecting block has a circular groove at its lower end, and each circular groove communicates with a corresponding strip-shaped opening. Each first connecting block has a cylindrical cavity inside, and a threaded groove is formed at the bottom of each cylindrical cavity. A screw is threaded through each threaded groove, and each screw is threaded to the inner wall of the corresponding threaded groove.

[0005] Preferably, each of the rectangular slots mates with a corresponding first connecting block.

[0006] Preferably, the inner diameter of each of the threaded grooves is smaller than the inner diameter of the cylindrical cavity.

[0007] Preferably, a limiting circular plate is fixedly connected to the upper end of each screw, and the outer side of each limiting circular plate is in contact with the inner wall of the columnar cavity and is slidably connected.

[0008] Preferably, each screw has a cross-shaped groove at its lower end.

[0009] Preferably, the inner diameter of each circular groove is greater than the front-to-back distance of the strip opening, the diameter of each screw is smaller than the front-to-back distance of the strip opening, and the lower end of each screw mates with the circular groove.

[0010] Compared with the prior art, the advantages of this utility model are as follows: After aligning the rectangular slots of the first connecting block and the second connecting block, the splicing can be completed by tightening the screws with a tool. No complicated operation steps are required, saving splicing time and labor costs. It can quickly build a safety protection structure and improve the installation efficiency of guardrails in milling and boring machining centers.

[0011] 2. The screws and the main body of the guardrail adopt an integrated design. The screws are fixed in the threaded groove of the first connecting block. During the splicing and subsequent use, the screws will not be lost, avoiding installation delays and unstable guardrail connections caused by lost screws.

[0012] 3. The screws are hidden after the final installation, which enhances the overall aesthetics. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-5 A safety guardrail for a milling and boring machining center includes a guardrail body 1. Multiple first connecting blocks 2 are fixedly connected to the left side wall of the guardrail body 1, and multiple second connecting blocks 3 are fixedly connected to the right side of the guardrail body 1. Each rectangular slot 9 mates with a corresponding first connecting block 2. Furthermore, the first connecting blocks 2 can be configured as follows: Figure 1 As shown, the first connecting block 2 is set on the left side wall of the left side part of the guardrail body 1 to connect two parallel guardrail bodies 1. At the same time, the first connecting block 2 can also be set on the rear side wall of the left side part of the guardrail body 1 to connect two perpendicular guardrail bodies 1. Each second connecting block 3 has a rectangular groove 9 on its right side, a strip-shaped opening 10 at the bottom of its inner side, a circular groove 11 at the bottom of its lower side, and each circular groove 11 communicating with the corresponding strip-shaped opening 10. Each first connecting block 2 has a cylindrical cavity 5 inside, a threaded groove 4 at the bottom of its inner side, a screw 7 passing through its inner side, a cross groove 8 at the bottom of its lower side, and a threaded connection between its inner side and the inner wall of its corresponding threaded groove 4. The inner diameter of each threaded groove 4 is smaller than the inner diameter of the cylindrical cavity 5. Each screw 7 has a fixed upper end connected to a limiting circular plate 6. The outer side of each limiting circular plate 6 is in contact with the inner wall of the columnar cavity 5 and is slidably connected. The inner diameter of each circular groove 11 is greater than the front and rear side distance of the strip-shaped opening 10. The diameter of each screw 7 is smaller than the front and rear side distance of the strip-shaped opening 10. The lower end of each screw 7 is engaged with the circular groove 11.

[0017] In this invention, when two guardrail bodies 1 need to be connected, the first connecting block 2 on the left side of one guardrail body 1 is aligned with the rectangular groove 9 on the second connecting block 3 on the right side of the other guardrail body 1. Since the diameter of each screw 7 is smaller than the front and rear side spacing of the slot 10, the first connecting block 2 can smoothly enter the rectangular groove 9 during the splicing process, at which point the screw 7 is located at the position of the slot 10. Next, the operator uses a Phillips screwdriver or other tools to insert into the Phillips groove 8 at the lower end of the screw 7 and tightens the screw 7. Since each screw 7 is threaded to the inner wall of the corresponding threaded groove 4, as the screw 7 rotates, the screw 7 will move upward along the threaded groove 4. At the same time, a limiting circular plate 6 is fixedly connected to the upper end of each screw 7. The outer side of the limiting circular plate 6 contacts and slides against the inner wall of the columnar cavity 5, and the limiting circular plate 6 can prevent the screw 7 from coming out of the threaded groove 4. When the screw 7 moves downwards until its lower end engages with the circular groove 11, since the inner diameter of each circular groove 11 is greater than the front and rear side spacing of the strip opening 10, the end of the screw 7 will be inserted into the circular groove 11, thereby fixing the first connecting block 2 in the rectangular groove 9 and realizing the splicing of the two guardrail bodies 1.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
