It achieves quick assembly and disassembly through an insertion and linkage locking mechanism. Its dual locking structure bears tensile stress and shear force respectively, ensuring safety and reliability. The modular design significantly improves efficiency and is aesthetically pleasing and durable.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fall-prevention production line staircase safety net, comprising a safety net, wherein assembly components are provided on the safety net for assembling the safety nets together, and the assembly components include:

[0007] The main components include the side frames located at the left and right ends of the protective netting;

[0008] The fixing component includes an upper frame set at the upper end of the protective net. The upper frame has secondary cavities at both the left and right ends.

A linkage component is set on the side frame for controlling the plug.

[0009] The connecting component includes a lower frame set at the lower end of the protective net. The lower frame has mounting heads fixed at both the left and right ends of the bottom and they cooperate with mounting holes. The lower end of the mounting head has a locking groove that cooperates with a locking rod. The inner walls of the front and rear ends of the locking groove have slots that cooperate with plugs.

[0010] Preferably, the linkage component includes a main cavity opened in the middle of the upper frame, a bidirectional lead screw rotatably installed between the left and right ends of the main cavity, a knob fixed on the outer wall of the middle part of the bidirectional lead screw, and internal thread sleeves threaded on the outer walls of both the left and right ends of the bidirectional lead screw. Connecting rods are fixed between the front and rear ends of the internal thread sleeves and the front and rear ends of the sliding sleeve.

[0011] Preferably, the linkage component further includes openings at both ends of the main cavity, and rubber plugs are inserted into the openings.

[0012] Preferably, the fixing component further includes sliding grooves formed on the outer walls of the front and rear ends of the locking rod, and the plug is slidably installed inside the sliding grooves.

[0015] Beneficial effects

[0016] This utility model provides a fall-prevention safety net for production line stairs. Compared with the prior art, it has the following advantages:

[0017] 1. By aligning the assembly head at the bottom of the lower frame of the connecting component with the assembly hole at the top of the upper frame of the fixing component and inserting it, the locking rod is embedded in the locking groove inside the assembly head, forming an initial vertical constraint. Subsequently, the linkage component is operated to drive the sliding sleeve fitted on the locking rod in the secondary cavity to slide axially, causing the plugs at its front and rear ends to move horizontally synchronously and finally insert into the slots on the front and rear inner walls of the locking groove, completing the lateral locking. The locking rod and the locking groove cooperate to bear the main tensile stress, and the plug and slot connection provides shear resistance and anti-disengagement protection, forming a double insurance mechanism. Modular quick installation and disassembly are achieved, which greatly improves installation efficiency and reduces maintenance difficulty. The built-in locking mechanism avoids the risk of damage to exposed parts. The overall structure is compact, beautiful and highly reliable.

[0018] 2. When the operator rotates the knob fixed in the middle of the double-acting screw, the double-acting screw is driven to rotate in the main cavity. Since the threads at the left and right ends of the double-acting screw are opposite, the two internal threaded sleeves screwed on it produce linear motions in opposite directions. Each internal threaded sleeve transmits this horizontal motion to the corresponding sliding sleeve through the connecting rods fixed at its front and rear ends, thereby ultimately driving the plug to accurately insert or withdraw from the slot. This ensures that the plugs on the left and right sides maintain the same displacement at all times, completely avoiding assembly interference or uneven force caused by locking on one side first.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a fall-prevention production line staircase safety net, including a safety net 1, and an assembly component 2 provided on the safety net 1 for assembling the safety nets 1 together. The assembly component 2 includes:

[0028] The main component 21 includes side frames 211 disposed at the left and right ends of the protective net 1;

[0029] The fixing component 22 includes an upper frame 221 set at the upper end of the protective net 1. The upper frame 221 has secondary cavities 222 at both the left and right ends. The secondary cavities 222 have assembly holes 223 at the upper end. A locking rod 224 is fixed between the left and right ends inside the secondary cavities 222. A sliding sleeve 226 is slidably installed on the locking rod 224. A plug 227 is fixed on the inner wall of both the front and rear ends of the sliding sleeve 226, and the outer end of the plug 227 extends to the outside of the sliding sleeve 226. A linkage component 228 is set on the side frame 211 and is used to control the plug 227.

[0030] The connecting component 23 includes a lower frame 231 set at the lower end of the protective net 1. The lower frame 231 has an assembly head 232 fixed at both the left and right ends of the bottom and cooperates with the assembly hole 223. The lower end of the assembly head 232 has a locking groove 233 that cooperates with the locking rod 224. The inner walls of the front and rear ends of the locking groove 233 have slots 234 that cooperate with the plug 227.

[0031] In this embodiment, by aligning the assembly head 232 at the bottom of the lower frame 231 of the connecting component 23 with the assembly hole 223 at the upper end of the upper frame 221 of the fixing component 22 and inserting it, the locking rod 224 is embedded in the locking groove 233 inside the assembly head 232, forming a preliminary vertical constraint. Subsequently, the linkage component 228 is operated to drive the sliding sleeve 226 sleeved on the locking rod 224 in the secondary cavity 222 to slide axially, causing the plugs 227 at both ends of the rod to move horizontally synchronously and finally insert into the slots 234 on the inner walls of the locking groove 233, thus completing the lateral locking. The locking rod 224 and the locking groove 233 cooperate to bear the main tensile stress, and the plugs 227 and the slots 234 provide anti-shear and anti-dislodgement protection, forming a double insurance mechanism. Modular quick installation and disassembly are realized, which greatly improves the installation efficiency and reduces the maintenance difficulty. The built-in locking mechanism avoids the risk of damage to exposed parts. The overall structure is compact, beautiful and highly reliable.

[0032] Specifically, the linkage component 228 includes a main cavity 2281 opened in the middle of the upper frame 221. A bidirectional lead screw 2282 is rotatably installed between the left and right ends of the main cavity 2281. A knob 2283 is fixed on the outer wall of the middle part of the bidirectional lead screw 2282. An internal threaded sleeve 2284 is threaded on the outer wall of both the left and right ends of the bidirectional lead screw 2282. A connecting rod 2285 is fixed between the front and rear ends of the internal threaded sleeve 2284 and the front and rear ends of the sliding sleeve 226.

[0033] In this embodiment, when the operator rotates the knob 2283 fixed in the middle of the bidirectional lead screw 2282, the bidirectional lead screw 2282 is driven to rotate in the main cavity 2281. Since the thread directions at the left and right ends of the bidirectional lead screw 2282 are opposite, the two internal thread sleeves 2284 screwed on it produce linear movements in opposite directions. Each internal thread sleeve 2284 transmits this horizontal movement to the corresponding sliding sleeve 226 through the connecting rod 2285 fixed at its front and rear ends, thereby ultimately driving the plug 227 to accurately insert or withdraw from the slot 234. This ensures that the plugs 227 on the left and right sides maintain the same displacement at any time, completely avoiding assembly interference or uneven force caused by locking on one side first.

[0034] Specifically, the linkage component 228 also includes openings 2286 at the front and rear ends of the middle of the main cavity 2281, and rubber plugs 2287 are inserted and installed in the openings 2286.

[0035] In this embodiment, when it is necessary to operate the knob 2283, the rubber plug 2287 can be pulled out, and the hand can be inserted into the main cavity 2281 through the opening 2286 to operate; after the operation or maintenance is completed, the rubber plug 2287 is tightly inserted into the opening 2286 for sealing and dust prevention.

[0036] Specifically, the fixing component 22 also includes a slide groove 225 formed on the outer wall of the front and rear ends of the locking rod 224, and the plug 227 is slidably installed inside the slide groove 225.

[0037] In this embodiment, when the connecting rod 2285 pushes the sliding sleeve 226 to move axially along the locking rod 224, the plug 227 fixed on the sliding sleeve 226 is forcibly constrained to slide within the narrow space of the sliding groove 225, so that the movement trajectory of the plug 227 is strictly limited to the horizontal direction, preventing it from undergoing any form of radial offset or circumferential rotation during movement.

[0038] Specifically, the main component 21 also includes fixing ears 212 on the upper and lower sides of the inner wall of the front end of the side frame 211, and the side frame 211 is fixed to the protective net 1 by fixing ears 212 and bolts.

[0039] Specifically, the ends of the upper frame 221 and the lower frame 231 are welded and fixed by the side frames 211 on both sides, forming a rectangular closed frame structure that fixes the protective net 1.

[0040] The working principle and usage process of this utility model are as follows: First, by aligning the assembly head 232 at the bottom of the lower frame 231 of the connecting component 23 with the assembly hole 223 at the upper end of the upper frame 221 of the fixing component 22 and inserting it, the locking rod 224 is embedded in the locking groove 233 inside the assembly head 232, forming a preliminary vertical constraint.

[0041] Then, when the operator turns the knob 2283 fixed in the middle of the bidirectional lead screw 2282, the bidirectional lead screw 2282 is driven to rotate in the main cavity 2281. Since the thread directions at the left and right ends of the bidirectional lead screw 2282 are opposite, the two internal thread sleeves 2284 screwed on it produce linear motions in opposite directions. Each internal thread sleeve 2284 transmits this horizontal motion to the corresponding sliding sleeve 226 through the connecting rods 2285 fixed at its front and rear ends.

[0042] Simultaneously, the sliding sleeve 226 drives the plugs 227 at its front and rear ends to move horizontally in sync and finally insert into the slots 234 on the front and rear inner walls of the locking groove 233, completing the lateral locking; the locking rod 224 and the locking groove 233 cooperate to bear the main tensile stress, and the plugs 227 and the slots 234 provide anti-shear and anti-disengagement protection, forming a double insurance mechanism; it realizes modular quick installation and quick disassembly, greatly improves installation efficiency and reduces maintenance difficulty, the built-in locking mechanism avoids the risk of damage to exposed parts, and the overall structure is compact, beautiful and highly reliable.
