Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a tightening machine for elastic woven steel wire mesh. Background Technology

[0002] In general, individual sections of fencing in sports fields are large and heavy, and the elastic woven steel wire mesh is inherently elastic with small mesh openings. Traditional construction methods require manual dragging and tightening, which is not only time-consuming and labor-intensive, but also often lacks the strength to properly tighten the fencing. For larger and longer fencing sections, additional minor mechanical investment is needed, increasing project costs. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a tightening machine for elastic woven steel wire mesh, which can quickly and labor-savingly tighten the mesh, shorten the construction period, and save construction costs.

[0004] To achieve the above objectives, the present invention provides a tightening machine for a flexible woven wire mesh fence, used to flatten and tighten the fence between two adjacent fence posts, wherein one end of the fence is fixed to one of the fence posts, and the tightening machine includes:

[0005] The box body has a slot that extends through the top of the box body in a first direction;

[0006] A fixing vise is provided on the box body and used to fix the box body to another of the fence railings;

[0007] Tightening components, including:

[0008] A sliding rod is slidably disposed in the slot along a first direction. The upper part of the sliding rod extends out of the slot and is fixedly installed with a chain that runs through the first direction. One end of the sliding rod along the first direction is connected to the other end of the enclosure net. Ratchets that run through the first direction are fixedly installed on both sides of the sliding rod.

[0009] A ratchet mechanism is provided above the slide bar and is used to cooperate with the tightening handle to drive the slide bar to slide in the slot along a first direction. The ratchet mechanism includes a ratchet rotatably mounted above the slide bar and a sprocket fixedly mounted on the outer ring of the ratchet and meshing with the chain. The tightening handle is connected to the ratchet.

[0010] The limiting component includes two limiting blocks that are slidably disposed relative to each other in the housing along a second direction. The two limiting blocks are respectively disposed on both sides of the slot and are symmetrically arranged with respect to the slot. Each of the two limiting blocks has a pawl that is arranged along a first direction and matches the ratchet on an opposite side. The second direction is perpendicular to the first direction.

[0011] Preferably, two connecting screws are provided on both sides of the ratchet, and two ear plates are fixedly installed on the top of the box. The two ear plates are respectively located on both sides of the slot and are symmetrically arranged about the slot. One end of each of the two connecting screws is fixedly connected to the ratchet, and the other end is respectively inserted into the two ear plates and rotatably connected to the corresponding ear plates.

[0012] Preferably, the other ends of the two connecting screws extend outward from the outer side of the corresponding ear plate and form two locking parts. The front end of the tightening handle forms a forked opening. The ratchet is accommodated in the forked opening. The front ends of the two rods at the forked opening are respectively provided with two latches for the two locking parts to engage with each other to connect the tightening handle to the ratchet.

[0013] Preferably, two adjusting bolts are fixedly connected to opposite sides of the two limiting blocks, and a compression spring is wound around each of the two adjusting bolts. One end of the compression spring is fixedly connected to the corresponding limiting block, and the other end is fixedly connected to the side wall of the corresponding box. The ends of the two adjusting bolts facing away from the corresponding limiting blocks pass through the side wall of the corresponding box and are used to engage with two adjusting nuts. During the tightening of the adjusting nuts, the two limiting blocks move away from each other until the slot for the slide rod to slide along the first direction is fully exposed. At this time, the compression spring is in a contracted state.

[0014] During the process of loosening the adjusting nut, the two limiting blocks move towards each other until the two pawls engage with the corresponding ratchet teeth. At this time, the compression spring is in an extended state.

[0015] Preferably, the fixing vise includes a baffle fixedly installed at the bottom of the box and a fixing platform adjustablely installed on the baffle along a first direction. The fixing platform, the baffle, and the box form an accommodating space for accommodating the fence railing. The fixing platform is adjustablely installed along a third direction for abutting against the fence railing, thereby fixing the box and the fence railing together. The third direction is perpendicular to both the second direction and the third direction.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects:

[0017] 1) By setting up a box, fixing a vise, and tightening components, the tightening components include a slide bar and a ratchet mechanism. The ratchet mechanism can be rotated by tightening the handle, which in turn drives the slide bar to slide in the slot to tighten the fence.

[0018] 2) By setting a limiting component, the pawl on the limiting block of the limiting component and the ratchet on the slide bar can cooperate to ensure that the slide bar will not slide in the opposite direction when the handle is reset, thus making the slide bar move in one direction, so as to facilitate the tightening of the fence.

[0019] 3) By setting a fixed vise, and in which the horizontal position of the fixed platform and the vertical position of the abutment can be adjusted, it can be used for fence railings of different widths and thicknesses, and the entire tightening machine can be firmly fixed to the fence railing.

Detailed Implementation

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Please see Figures 1 to 6 As shown, this embodiment of the invention provides a tightening machine for elastic woven wire mesh fencing, used to flatten and tighten the fencing between two adjacent fence posts. One end of the fencing is fixed to one of the fence posts. The tightening machine includes a housing 11, a fixing vise 2, a tightening assembly, and a limiting assembly. The top of the housing 11 has a slot 12 extending along a first direction. The fixing vise 2 is mounted on the housing 11 and used to fix the housing 11 to the other fence post. The tightening assembly includes a sliding rod 31 and a ratchet mechanism 4. The sliding rod 31 is slidably disposed within the slot 12 along the first direction. The upper part of the slide bar 31 extends out of the slot 12 and is fixedly installed with a chain 33 that runs through the first direction. One end of the slide bar 31 along the first direction is connected to the other end of the fence. Both sides of the slide bar 31 are fixedly installed with ratchet teeth 34 that run through the first direction. The ratchet mechanism 4 is located above the slide bar 31 and is used to cooperate with the tightening handle 5 to drive the slide bar 31 to slide in the slot 12 along the first direction. The ratchet mechanism 4 includes a ratchet 41 that is rotatably installed above the slide bar 31 and a sprocket 42 that is fixedly installed on the outer ring of the ratchet 41 and meshes with the chain 33. The tightening handle 5 is connected to the ratchet 41.

[0031] Furthermore, the limiting component includes two limiting blocks 61 that are slidably disposed relative to each other within the housing 11 along a second direction. The two limiting blocks 61 are respectively disposed on both sides of the slot 12 and are symmetrically arranged with respect to the slot 12. Each of the two limiting blocks 61 has a pawl 62 that extends along the first direction and matches the ratchet 34 on one side opposite to each other. The second direction is perpendicular to the first direction. It should be noted that, in this embodiment, a gripping rod 32 for attaching a net is fixedly connected to one end of the slide rod 31 along the first direction. The top of the housing 11 is provided with a cover plate 14, and the slot 12 is opened at the middle position of the cover plate 14.

[0032] Please see Figure 1 and Figure 3 As shown, in this embodiment, two connecting screws 43 are provided on both sides of the ratchet 41, and two ear plates 13 are fixedly installed on the top of the box 11. The two ear plates 13 are respectively provided on both sides of the slot 12 and are symmetrically arranged relative to the slot 12. One end of each of the two connecting screws 43 is fixedly connected to the ratchet 41, and the other end is respectively inserted into the two ear plates 13 and rotatably connected to the corresponding ear plates 13. Each of the two ear plates 13 has a hole for inserting the corresponding connecting bolt 43.

[0033] Furthermore, in this embodiment, the other ends of the two connecting screws 43 extend outward from the corresponding ear plates 13 and form two locking portions 45. The front end of the tightening handle 5 forms a forked opening 51, and the ratchet 41 is accommodated in the forked opening 51. The front ends of the two rods 52 at the forked opening 51 are respectively provided with two latches 53 for the two locking portions 45 to engage with each other to connect the tightening handle 5 to the ratchet 41. It should be noted that in this embodiment, one end of each of the two connecting bolts 43 is fixedly connected to the shaft of the ratchet 41. A washer 44 is provided at the connection between the ratchet 41 and the connecting bolts 43. The washer 44 can reduce friction.

[0034] Please see Figure 1 and Figure 4 As shown, in this embodiment, two adjusting bolts 63 are fixedly connected to opposite sides of the two limiting blocks 61. Compression springs (not shown in the figure) are wound around the two adjusting bolts 63 respectively. One end of the compression spring is fixedly connected to the corresponding limiting block 61, and the other end is fixedly connected to the side wall of the corresponding box 11. The ends of the two adjusting bolts 63 facing away from the corresponding limiting blocks 61 pass through the side wall of the corresponding box 11 and are used to cooperate with two adjusting nuts 64. During the tightening of the adjusting nuts 64, the two limiting blocks 61 move away from each other until the slot 12 for the slide rod 31 to slide in the first direction is fully exposed. At this time, the compression spring is in a contracted state, and the slide rod 31 can move freely in the slot 12.

[0035] During the process of loosening the adjusting nut 64, the two limit blocks 61 move towards each other until the two pawls 62 engage with the corresponding ratchet teeth 34. At this time, the compression spring is in an extended state, and the ratchet teeth 34 on the slide rod 31 are held in place by the pawls 62, so it can only move in one direction.

[0036] Please see Figure 1 and Figure 5 As shown, in this embodiment, the fixed vise 2 includes a baffle 21 fixedly installed at the bottom of the box 11 and a fixed platform 22 adjustablely installed on the baffle 21 along a first direction. The fixed platform 22, the baffle 21 and the box 11 form an accommodating space for accommodating the fence railing. The fixed platform 22 is also adjustablely installed with a pusher 23 along a third direction for pushing against the fence railing, thereby fixing the box 11 and the fence railing together. It should be noted that in this embodiment, a lead screw 24 is inserted and installed on the baffle 21. One end of the lead screw 24 passes through the baffle 21 and is welded and fixed to the fixed platform 22. By setting the lead screw 24 and cooperating with the fixing nut 26, the position of the fixed platform 22 in the first direction (i.e., the horizontal direction) can be adjusted. The abutment 23 is also a lead screw. The lead screw is inserted on the fixed platform 22, and one end of the lead screw passes through the fixed platform 22 and is fixedly installed with the abutment plate 25. By cooperating with the abutment 23 and the fixing nut 26, the position of the abutment plate 25 in the third direction (i.e., the vertical direction) can be adjusted, so that fence railings of different widths and thicknesses can be used. The third direction is perpendicular to the first direction and the second direction respectively. In this embodiment, the other end of the abutment 23, i.e. the lead screw 24, is fixedly installed with a handle 27. The baffle 21 and the fixed platform 22 are both made of steel plate.

[0037] The construction principle of tightening a flexible woven steel wire mesh using a tightening machine according to an embodiment of the present invention includes:

[0038] 1) Using a fixed vise, fix the box to the fence railing on the side that needs to be tightened. Adjust the abutment and screw according to the width and thickness of the fence railing, and tighten the corresponding fixing nuts to ensure that the fixed vise is firmly fixed to the fence railing and will not slip.

[0039] 2) Tighten the adjusting nut so that the two limit blocks move in opposite directions into the inside of the box. At this time, the compression spring is in a compressed state and the slot is fully exposed. Pull out the slide rod to a suitable length and fix it to the fence through the gripping rod.

[0040] 3) Loosen the adjusting nut so that the two limit blocks move towards each other until the ratchet on the slide bar engages with the pawl on the limit block. At this time, the compression spring is in the pop-out state, and the pawl holds the ratchet, so that the slide bar can only move in one direction.

[0041] 4) Engage the tightening handle with the locking part at the end of the connecting screw through the fork-shaped opening. Move the tightening handle upward to rotate the ratchet and sprocket, causing the slide bar to slide backward and gradually tighten the netting. Then reset the tightening handle. At this time, the slide bar will not reset because the ratchet teeth on the slide bar are held in place by the pawl. Move the tightening handle upward again, and the slide bar will continue to move backward.

[0042] 5) Repeat the operation until the other end of the fence is tightened to the edge of the fence railing. After the fence and the fence railing are fixed, separate the tightening handle from the ratchet, tighten the adjusting nut to release the slide bar in the slot, and then loosen the fixing nut on the fixing vise to remove the fence railing.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
