Description

Technical Field

[0001] This utility model relates to the field of safety protection equipment technology, and in particular to a safety guardrail with a quick-release base. Background Technology

[0002] Equipment safety barriers, as an important safety protection facility, are widely used in factory workshops, construction sites, and around various mechanical equipment to isolate dangerous areas, prevent accidental entry, and ensure personal safety. In many applications, these safety barriers are not permanently fixed but need to be temporarily dismantled, moved, and reinstalled according to changes in production operations, equipment maintenance, or site layout.

[0003] To meet this need for flexibility, traditional guardrails and bases are often connected using bolts. While this method is simple and secure, its drawbacks are significant in situations requiring frequent disassembly and reassembly. Each installation or disassembly requires workers to tighten or loosen multiple bolts one by one using wrenches and other tools, a tedious, time-consuming, and labor-intensive process that greatly reduces on-site work efficiency and fails to meet the demands of rapid response and efficient deployment in modern production management.

[0004] To address the aforementioned problem of inefficient assembly and disassembly, some quick-release guardrails using simple pins or spring clips have emerged on the market. While these designs do achieve tool-free assembly and disassembly, improving convenience to some extent, these simple quick-release structures often sacrifice connection reliability in pursuit of speed. In industrial environments with equipment vibration or potential accidental collisions, a single clip or pin structure has limited locking force and is prone to loosening or even accidental detachment due to continuous vibration or external impact, leading to sudden failure of the safety guardrail and posing a serious safety hazard.

[0005] Therefore, this utility model proposes a safety guardrail with a quick-release base to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a device safety railing with a quick-release base, aiming to improve the problems of cumbersome and time-consuming disassembly and assembly processes of existing device safety railings, as well as the safety hazards caused by insufficient connection reliability of existing quick-release structures. This utility model aims to provide a device safety railing with a quick-release base that has been structurally improved and can effectively solve the above problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a safety guardrail with a quick-release base, comprising a counterweight base and a guardrail body, wherein the counterweight base has an installation groove, and the bottom of the guardrail body is fixedly connected to an installation block that can be inserted into the installation groove; the safety guardrail further comprises a quick-release locking mechanism disposed in the installation groove, and a secondary positioning mechanism disposed on the counterweight base.

[0008] The quick-release locking mechanism includes an adjusting rod slidably disposed in a sliding groove within the inner wall of the mounting groove, a snap-fit ​​block fixedly connected to or integrally formed with the adjusting rod, and a spring disposed between the snap-fit ​​block and the inner wall of the mounting groove; the secondary positioning mechanism includes a positioning plate fixed within the counterweight base, a threaded rod threadedly connected to the positioning plate, and a positioning hole formed on the adjusting rod and capable of engaging with the end of the threaded rod.

[0009] Preferably, a guide block is fixedly connected to the bottom of the snap-fit ​​block, and a guide frame is fixedly connected to the bottom of the mounting groove. The guide block is slidably fitted within the guide frame to provide precise guidance for the reciprocating motion of the snap-fit ​​block.

[0010] Preferably, the guide frame has a long strip structure with a U-shaped cross-section to achieve a stable sliding fit.

[0011] Preferably, the mounting block has a snap-fit ​​groove for the snap-fit ​​block to snap into, so as to achieve reliable snap-fit ​​fixation.

[0012] Preferably, the counterweight base also has a positioning groove that communicates with the positioning plate, and the threaded rod passes through the positioning groove and is threadedly connected to the positioning plate, so as to facilitate operation of the threaded rod from the outside.

[0013] Preferably, the equipment safety railing further includes a protective cover, which is rotatably connected to the outer wall of the counterweight base via a pivot.

[0014] Preferably, the protective cover, when closed, can shield the external openings of the sliding groove and the positioning hole, thereby protecting the internal mechanism from external debris.

[0015] Preferably, the equipment safety escort also includes a storage box, which is fixed inside the mounting slot and away from the position of the quick-release locking mechanism, for holding items such as desiccant.

[0016] This utility model has the following beneficial effects:

[0017] 1.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please refer to Figures 1 to 4This utility model provides a device safety guardrail with a quick-release base, which aims to solve the problems of cumbersome disassembly and assembly and insufficient connection reliability of the connection structure between the safety guardrail and the base in the prior art.

[0027] like Figure 1 and Figure 2 As shown, the equipment safety guardrail with quick-release base includes a counterweight base 1 as the installation base and a guardrail body 2 for safety protection. The counterweight base 1 has an installation groove 3. An installation block 301 is fixedly connected to the bottom of the guardrail body 2. The installation block 301 can be detachably inserted into the installation groove 3. In order to achieve quick locking and separation between the guardrail body 2 and the counterweight base 1, a quick-release locking mechanism is provided in the installation groove 3. At the same time, in order to improve the stability and safety of the connection, a secondary positioning mechanism is also provided on the counterweight base 1.

[0028] The inner wall of the mounting groove 3 is provided with a sliding groove 302. The quick-release locking mechanism includes an adjusting rod 303, a snap-fit ​​block 304 and a spring 305. The adjusting rod 303 is slidably disposed in the sliding groove 302. The snap-fit ​​block 304 is fixedly connected to the adjusting rod 303 or integrally formed. The two ends of the spring 305 abut against the snap-fit ​​block 304 and the inner wall of the mounting groove 3, respectively. When the mounting block 301 is inserted into the mounting groove 3, the snap-fit ​​block 304 snaps against the mounting block 301 under the elastic force of the spring 305, thereby completing the initial locking.

[0029] Reference Figure 3 and Figure 4 The secondary positioning mechanism is used to further reinforce the quick-release locking mechanism after the initial locking is completed. The secondary positioning mechanism includes a positioning plate 601 fixed in the counterweight base 1 and a threaded rod 602 threadedly connected to the positioning plate 601. The adjusting rod 303 has a positioning hole 603. By rotating the threaded rod 602, the end of the threaded rod 602 is inserted into the positioning hole 603, thereby physically limiting the adjusting rod 303, locking the position of the adjusting rod 303, and preventing the quick-release locking mechanism from being accidentally unlocked.

[0030] A guide block 4 is fixedly connected to the bottom of the snap-fit ​​block 304 as a sliding component; a guide frame 5 is fixedly connected to the bottom of the mounting groove 3 corresponding to the position of the guide block 4. The guide frame 5 is a long strip structure with a U-shaped cross section, which provides a sliding track for the guide block 4. In the assembled state, the guide block 4 slides in the guide frame 5. This sliding fit structure between the guide block 4 and the guide frame 5 ensures that the snap-fit ​​block 304 maintains a smooth linear movement during the reciprocating motion driven by the adjusting rod 303, effectively preventing the snap-fit ​​block 304 from tilting or jamming, thereby improving the smoothness and reliability of the disassembly and assembly operation.

[0031] The secondary positioning mechanism also includes a positioning groove 6 that is opened on the counterweight base 1 and communicates with the positioning plate 601. The threaded rod 602 passes through the positioning groove 6 and is threadedly connected to the positioning plate 601, which facilitates external operation.

[0032] To protect the internal precision mechanism, a protective cover 7 is rotatably connected to the outer wall of the counterweight base 1 via a pivot. When closed, the protective cover 7 can cover the external openings of the sliding groove 302 and the positioning hole 603, preventing dust, rainwater and other external debris from entering the mechanism and causing damage or affecting the sensitivity of the action.

[0033] To slow down the corrosion of internal metal parts, a storage box 8 is fixed inside the mounting slot 3, away from the quick-release locking mechanism. A desiccant can be placed in the storage box 8 to absorb the humid air inside the mounting slot 3.

[0034] In a preferred embodiment, in order to achieve a stable and reliable snap-fit ​​between the snap-fit ​​block 304 and the mounting block 301, the mounting block 301 is provided with a snap-fit ​​groove for the snap-fit ​​block 304 to snap into.

[0035] As another preferred embodiment, in order to further improve the stability of the quick-release locking mechanism during operation, a guide block 4 is fixedly connected to the bottom of the snap-fit ​​block 304, and a guide frame 5 is fixedly connected to the bottom of the mounting groove 3. The guide block 4 can slide inside the guide frame 5. The guide frame 5 is preferably a long strip structure with a U-shaped cross section, which provides a clear sliding path for the guide block 4.

[0036] As another preferred embodiment, in order to facilitate the operation of the threaded rod 602, the secondary positioning mechanism also includes a positioning groove 6 formed on the counterweight base 1 and communicating with the positioning plate 601. The threaded rod 602 passes through the positioning groove 6 from the outside of the counterweight base 1 and thus achieves a threaded connection with the positioning plate 601.

[0037] As another preferred embodiment, to protect the internal quick-release locking mechanism and secondary positioning mechanism, refer to... Figure 1 A protective cover 7 is rotatably connected to the outer wall of the counterweight base 1 via a rotating shaft. When rotated to the closed state, the protective cover 7 can cover the external openings of the sliding groove 302 and the positioning hole 603.

[0038] As another preferred embodiment, in order to extend the service life of the internal metal components, a storage box 8 is fixed inside the mounting groove 3 and in a position that avoids the quick-release locking mechanism. The storage box 8 is used to hold desiccant.

[0039] Working principle: During installation, align the mounting block 301 at the bottom of the guardrail body 2 with the mounting slot 3 of the counterweight base 1. During the insertion process, the mounting block 301 will squeeze the snap-fit ​​block 304, forcing the snap-fit ​​block 304 to move smoothly under the guidance of the guide block 4 and the guide frame 5 and compress the spring 305. When the mounting block 301 is fully inserted, the snap-fit ​​block 304 will automatically reset under the rebound force of the spring 305 and snap into the snap-fit ​​groove of the mounting block 301, completing a quick initial locking. Then, rotate the threaded rod 602 so that the end of the threaded rod 602 is screwed into and fixed in the positioning hole 603 of the adjusting rod 303, completing the secondary locking of the adjusting rod 303 and ensuring the firmness of the connection.

[0040] During disassembly, first rotate the threaded rod 602 in the reverse direction to disengage it from the positioning hole 603, thus releasing the lock on the adjusting rod 303. Then, manually push the adjusting rod 303, which causes the locking block 304 to compress the spring 305 again, causing the locking block 304 to disengage from the locking groove of the mounting block 301. At this point, the lock on the mounting block 301 is released, and the guardrail body 2 can be pulled upwards for quick separation.
