Description

Technical Field

[0001] The invention belongs to the technical field of construction tools, and in particular relates to a safety buckle. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. It is divided into external scaffolding and internal scaffolding according to the location of the scaffolding. By connecting the protective rope to the scaffolding and then tying the protective rope to the construction workers, the construction workers can be effectively protected.

[0003] The utility model patent with patent application number CN201520181316.5 discloses a scaffold safety fastening device for construction, which connects the outer wall of the building with the steel pipe of the scaffold. The scaffold safety fastening device includes: a plurality of fasteners, which are arranged at intervals on the outer wall of the building, and each includes a nut embedded in the outer wall of the building, and a handle that can be detachably assembled with the nut, the handle includes a rod extending into the nut, and a ring is provided at one end of the rod; and at least one safety belt, one end of the safety belt is tied to the ring of one of the fasteners, the safety belt is wrapped around the steel pipe of the scaffold, and the other end of the safety belt is tied to the ring of another adjacent fastener. The utility model can increase the convenience of disassembly and assembly, and the nut after the handle is removed will not affect the beauty of the building's appearance. The safety belt is wrapped around the outer column of the steel pipe of the scaffold, so that the scaffold will not have lateral displacement of the frame column due to wind, earthquake or uneven load on the workbench above the scaffold.

[0004] The above-mentioned safety fastening device needs to be connected to the top of the upper scaffolding to achieve "high hanging and low use". However, in the early stage of cantilever scaffolding erection, there is no component at the top of the uppermost floor to fix the safety rope, which makes it impossible to "hang high and use low". The construction workers can only tie the safety rope to the embedded parts of the floor slab, which is in a "low hanging and high use" state, greatly reducing the safety protection ability of the safety rope. Summary of the invention

[0005] In order to solve the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a safety buckle that can be reliably connected to a steel pipe, thereby solving the problem that there is no component on the top of the cantilever scaffolding to fix the protection rope in the initial stage of construction and the safety buckle of the existing protection rope cannot be reliably connected to the upright steel pipe.

[0006] The technical solution adopted by the present invention is:

[0007] A safety buckle includes an internal threaded hoop sleeved on a steel pipe, an opening is provided on the internal threaded hoop, the opening passes through the internal threaded hoop from the axial direction, a base and an inner cover for tightening the internal threaded hoop and the steel pipe are respectively threadedly connected on the internal threaded hoop, a rope hole is provided on the base or the inner cover or between the base and the inner cover, a protective rope is wound around the internal threaded hoop, and both ends of the protective rope pass through the rope hole. When the base and the inner cover are respectively screwed onto the internal threaded hoop, the internal threaded hoop is tightened, and the opening of the internal threaded hoop is narrowed, so that the internal threaded hoop can be in close contact with the steel pipe. After the internal threaded hoop is tightened by the base and the inner cover, it is reliably connected to the steel pipe, and the internal threaded hoop is prevented from sliding on the steel pipe. Since the internal threaded hoop is reliably connected, the positions of the base and the inner cover are determined accordingly, and after the protective rope passes through the rope hole, the position of the protective rope will not move, thereby ensuring that the protective rope can be "hung high and used low", ensuring safe use.

[0008] As a preferred solution of the present invention, the internal threaded hoop is also threadedly connected with a top cover, which is located on the side of the inner cover away from the bottom bracket. The top cover can further tighten the internal threaded hoop, and the top cover, the inner cover and the bottom bracket all tighten the internal threaded hoop, ensuring that each section of the internal threaded hoop is in close contact with the steel pipe, ensuring sufficient friction, and preventing the internal threaded hoop from sliding on the steel pipe.

[0009] As a preferred solution of the present invention, an external connection sleeve is further provided in the top cover, and an external thread is provided on the inner cover, and the external connection sleeve is threadedly connected to the external thread of the inner cover. The external connection sleeve on the top cover is threadedly connected to the inner cover, and the inner cover, the top cover and the internal threaded hoop are threadedly connected in pairs, and the three restrict each other to prevent the inner cover or the top cover from rotating relative to the internal threaded hoop, so that the position of the rope hole is accurate, further improving the safety of the present invention.

[0010] As a preferred solution of the present invention, a sealing ring is provided at one end of the top cover away from the inner cover, and the sealing ring is sleeved on the steel pipe. The sealing ring can shield the threaded connection between the internal threaded hoop and the top cover to prevent impurities from falling between the threads.

[0011] As a preferred solution of the present invention, the base includes a base body, a base thread sleeve is fixed inside the base body, and the base thread sleeve is threadedly connected to the internal threaded hoop; the inner cover includes an inner cover body, an inner cover thread sleeve is fixed on the inner cover body, and the inner cover thread sleeve is threadedly connected to the internal threaded hoop; the rope hole is set in the base body or the inner cover body or between the base body and the inner cover body. The inner diameters of the large ends of the base body and the inner cover body are both larger than the diameter of the internal threaded hoop, so that after the protective rope is wound, the base body and the inner cover body have enough space to accommodate the protective rope.

[0012] As a preferred solution of the present invention, the bottom support body is provided with a bottom support annular cover, the inner cover body is provided with a bottom support annular cover, the bottom support annular cover and the inner cover annular cover are assembled, and the rope hole is provided between the bottom support body and the inner cover body. The surfaces of the bottom support annular cover and the bottom support annular cover are both annular surfaces, so when the rope hole is provided between the bottom support body and the inner cover body, the direction of the rope hole is in a horizontal position, which facilitates the movement of the protection rope in the rope hole and reduces the friction of the protection rope in the rope hole.

[0013] As a preferred solution of the present invention, a protective cover is connected to the rope hole, and both ends of the protection rope pass through the protective cover. The protective cover can protect the protection rope to prevent the protection rope from being cut by the inner cover or the bottom bracket. The protective cover can also prevent the bottom bracket and the inner cover from rotating relative to each other, so that the inner cover and the bottom bracket restrain each other to prevent the bottom bracket or the inner cover from falling off from the internal threaded hoop.

[0014] As a preferred solution of the present invention, the bottom support annular cover and the inner cover annular cover are both provided with semicircular tubes at the rope hole, the two semicircular tubes are spliced ​​together, and the protective cover is threadedly connected to the two semicircular tubes after splicing. The protective cover is threadedly connected to the two semicircular tubes, which is convenient for disassembly and assembly of the protective cover, and the connection is more reliable.

[0015] As a preferred solution of the present invention, the internal threaded hoop is also threadedly connected with a top cover, which is located on the side of the inner cover away from the bottom bracket; the top cover is provided with a top cover collar, which is sleeved on the inner cover body. After the top cover is screwed into place, the top cover collar is sleeved on the bottom bracket body, so that the connection between the top cover and the inner cover is more reliable, and the inner cover can limit the top cover.

[0016] As a preferred solution of the present invention, a rope ring is fixed inside the base, and the protective rope is wound around the rope ring. The protective rope is wound around the rope ring to avoid the situation where the protective rope is easily damaged when it directly contacts the internal threaded hoop.

[0017] The beneficial effects of the present invention are:

[0018] 1. The internal threaded hoop of the present invention can be tightened by the inner cover and the bottom bracket, and the opening of the internal threaded hoop is narrowed, so that the internal threaded hoop can be in close contact with the steel pipe, thereby preventing the internal threaded hoop from sliding on the steel pipe. Since the internal threaded hoop is reliably connected, the positions of the bottom bracket and the inner cover are determined accordingly, and after the protective rope passes through the rope hole, the position of the protective rope will not move, thereby ensuring that the protective rope can be "hung high and used low", ensuring safe use.

[0019] 2. The top cover can further tighten the internal threaded hoop. The top cover, the inner cover and the bottom support can tighten the internal threaded hoop to ensure that each section of the internal threaded hoop is in close contact with the steel pipe, ensuring sufficient friction to prevent the internal threaded hoop from sliding on the steel pipe. The external connecting sleeve on the top cover is threadedly connected to the inner cover, and the inner cover, the top cover and the internal threaded hoop are threadedly connected in pairs. The three restrict each other to prevent the inner cover or the top cover from rotating relative to the internal threaded hoop, so that the position of the rope hole is accurate, further improving the safety of the present invention.

[0020] 3. The protective cover can also prevent the bottom bracket and the inner cover from rotating relative to each other, so the inner cover and the bottom bracket restrict each other. In addition, the inner cover and the outer connecting sleeve of the top cover are threadedly connected, so that the connection reliability between the inner cover and the internal threaded hoop is greatly improved. After the present invention is installed, the inner cover will not rotate relative to the internal threaded hoop. Therefore, when the position of the inner cover is stable, the position of the bottom bracket is relatively fixed, so as to prevent the bottom bracket or the inner cover from falling off from the internal threaded hoop and ensure the stability of the rope hole position.

DETAILED DESCRIPTION

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figure 1 and Figure 2As shown, the safety buckle of this embodiment includes an internal threaded hoop 2 sleeved on a steel pipe 1, the internal threaded hoop 2 is provided with an opening 21, the opening 21 passes through the internal threaded hoop 2 axially, the internal threaded hoop 2 is respectively threadedly connected with a base 3 and an inner cover 4 for clamping the internal threaded hoop 2 and the steel pipe 1, a rope hole 5 is provided between the base 3 or the inner cover 4 or the base 3 and the inner cover 4, a protection rope 6 is wound around the internal threaded hoop 2, and both ends of the protection rope 6 pass through the rope hole 5.

[0027] In the early stage of building the cantilever scaffold, there is no component on the top of the uppermost floor to fix the protection rope 6. However, there are many vertical steel pipes 1 on the scaffold, and the upper ends of the steel pipes 1 are not connected to other structures. The present invention can be inserted from the upper open end of the steel pipe 1 and then reliably connected.

[0028] After the internal threaded hoop 2 is inserted into the steel pipe 1, the bottom bracket 3 and the inner cover 4 are threadedly connected to the internal threaded hoop 2 in turn. When the bottom bracket 3 and the inner cover 4 are screwed onto the internal threaded hoop 2 respectively, the internal threaded hoop 2 is tightened, and the opening 21 of the internal threaded hoop 2 is narrowed, so that the internal threaded hoop 2 can be in close contact with the steel pipe 1. After the internal threaded hoop 2 is tightened by the bottom bracket 3 and the inner cover 4, it is reliably connected to the steel pipe 1 to prevent the internal threaded hoop 2 from sliding on the steel pipe 1. Since the internal threaded hoop 2 is reliably connected, the positions of the bottom bracket 3 and the inner cover 4 are determined accordingly. After the protective rope 6 passes through the rope hole 5, the position of the protective rope 6 will not move, thereby ensuring that the protective rope 6 can be "hung high and used low" to ensure safe use.

[0029] In order to further improve the connection reliability between the internal threaded hoop 2 and the steel pipe 1, a top cover 7 is also threadedly connected to the internal threaded hoop 2, and the top cover 7 is located on the side of the inner cover 4 away from the bottom support 3. The top cover 7 can further tighten the internal threaded hoop 2, and the top cover 7, the inner cover 4 and the bottom support 3 all tighten the internal threaded hoop 2, ensuring that each section of the internal threaded hoop 2 is in close contact with the steel pipe 1, ensuring sufficient friction, and preventing the internal threaded hoop 2 from sliding on the steel pipe 1.

[0030] In order to prevent the bottom support 3, the inner cover 4 or the top cover 7 from rotating on the internal threaded hoop 2, an external connection sleeve 71 is further provided in the top cover 7, and an external thread is provided on the inner cover 4, and the external connection sleeve 71 is threadedly connected with the external thread of the inner cover 4. The external connection sleeve 71 on the top cover 7 is threadedly connected with the inner cover 4, and the inner cover 4, the top cover 7 and the internal threaded hoop 2 are threadedly connected in pairs, and the three restrict each other to prevent the inner cover 4 or the top cover 7 from rotating relative to the internal threaded hoop 2, so that the position of the rope hole 5 is accurate, and the safety of the present invention is further improved.

[0031] like Figure 3As shown, the rope hole 5 is arranged between the base 3 and the inner cover 4, and the base annular cover 311 and the inner cover annular cover 411 are both provided with semicircular tubes 9 at the rope hole 5, and the two semicircular tubes 9 are spliced. The two semicircular tubes 9 are threadedly connected with the protective cover 8, and the protective rope 6 passes through the protective cover 8. The protective cover 8 prevents the base 3 and the inner cover 4 from rotating relative to each other, so the inner cover 4 and the base 3 restrict each other. In addition, the inner cover 4 is threadedly connected to the external connecting sleeve 71 of the top cover 7, so that the connection reliability between the inner cover 4 and the internal threaded hoop 2 is greatly improved. After the present invention is installed, the inner cover 4 will not rotate spirally relative to the internal threaded hoop 2. Therefore, when the position of the inner cover 4 is stable, the position of the base 3 is relatively fixed, so as to prevent the base 3 or the inner cover 4 from falling off from the internal threaded hoop 2, and ensure the stability of the position of the rope hole 5.

[0032] The protective cover 8 can protect the protective rope 6 to prevent the protective rope 6 from being cut by the inner cover 4 or the bottom bracket 3. When installing the protective rope 6, a gap is left between the inner cover 4 and the bottom bracket 3, and the protective rope 6 can be directly sleeved on the internal threaded hoop 2 or the rope ring 33, which is convenient for operation. If the rope hole 5 is set on the bottom bracket 3 or the inner cover 4, it is necessary to first pass the protective rope 6 through the rope hole 5, then wrap the protective rope 6 around the internal threaded hoop 2 or the rope ring 33, and then pass it through the rope hole 5, which is troublesome to operate. When the rope hole 5 is directly set between the bottom bracket 3 and the inner cover 4, the operation is simpler.

[0033] In order to prevent impurities from falling into the threaded connection between the top cover 7 and the internal threaded hoop 2, a sealing ring 72 is provided at one end of the top cover 7 away from the inner cover 4, and the sealing ring 72 is sleeved on the steel pipe 1. The sealing ring 72 can shield the threaded connection between the internal threaded hoop 2 and the top cover 7 to prevent impurities from falling between the threads. If there is no impurity intrusion into the threaded connection between the top cover 7 and the internal threaded hoop 2, the top cover 7 can be screwed smoothly when disassembling or installing the top cover 7, avoiding the situation where the top cover 7 is not screwed into place.

[0034] In order to protect the protection rope 6, the bottom support 3 includes a bottom support body 31, a bottom support threaded sleeve 32 is fixed inside the bottom support body 31, and the bottom support threaded sleeve 32 is threadedly connected to the internal threaded hoop 2; the inner cover 4 includes an inner cover body 41, an inner cover threaded sleeve 42 is fixed on the inner cover body 41, and the inner cover threaded sleeve 42 is threadedly connected to the internal threaded hoop 2; the rope hole 5 is set in the bottom support body 31 or the inner cover body 41 or between the bottom support body 31 and the inner cover body 41. The inner diameters of the large ends of the bottom support body 31 and the inner cover body 41 are both larger than the diameter of the internal threaded hoop 2. After the protection rope 6 is wound, the bottom support body 31 and the inner cover body 41 have enough space to accommodate the protection rope 6, so that the protection rope 6 is protected.

[0035] Furthermore, the bottom support body 31 is provided with a bottom support annular cover 311, the inner cover body 41 is provided with a bottom support annular cover 311, the bottom support annular cover 311 and the inner cover annular cover 411 are assembled, and the rope hole 5 is provided between the bottom support body 31 and the inner cover body 41. The surfaces of the bottom support annular cover 311 and the bottom support annular cover 311 are both annular surfaces, so when the rope hole 5 is provided between the bottom support body 31 and the inner cover body 41, the direction of the rope hole 5 is in a horizontal position, which facilitates the movement of the protection rope 6 in the rope hole 5 and reduces the friction of the protection rope 6 in the rope hole 5.

[0036] In order to further improve the tightness of the connection between the top cover 7 and the inner cover 4, a top cover collar 73 is provided on the top cover 7, and the top cover collar 73 is sleeved on the inner cover body 41. After the top cover 7 is screwed into place, the top cover collar 73 is sleeved on the inner cover body 41, so that the connection between the top cover 7 and the inner cover 4 is more reliable, and the inner cover 4 can limit the top cover 7.

[0037] Furthermore, a rope ring 33 is fixed inside the base 3, and the protection rope 6 is wound around the rope ring 33. The protection rope 6 is wound around the rope ring 33 to avoid the situation where the protection rope 6 is easily damaged when the protection rope 6 directly contacts the internal threaded hoop 2.

[0038] Working principle:

[0039] In the early stage of building the cantilever scaffold, there is no component at the top of the uppermost part of the floor to fix the protection rope 6. There are many vertical steel pipes 1 on the scaffold, and the upper end of the steel pipe 1 has not been connected to other structures, that is, the upper end of the steel pipe 1 is an open end. The internal threaded hoop 2 with an opening 21 is inserted into the steel pipe 1 from the upper end of the steel pipe 1, and then the bottom bracket 3, the inner cover 4 and the top cover 7 are threadedly connected to the internal threaded hoop 2 in sequence. A certain gap is reserved between the bottom bracket 3 and the inner cover 4, and the protection rope 6 is wound around the rope ring 33 in the bottom bracket 3 from the gap between the bottom bracket 3 and the inner cover 4, and then the two ends of the protection rope 6 are passed through the semicircular tube 9 and the protective cover on the bottom bracket 3. Screw the inner cover 4 to the position where it is spliced ​​with the two semicircular tubes 9, and screw the protective cover onto the two semicircular tubes 9, then the connection of the protection rope 6 is completed, and the inner cover 4 and the bottom bracket 3 are reliably connected. The top cover 7 is screwed so that the external connection sleeve 71 in the top cover 7 is connected with the external thread on the inner cover 4, and the top cover collar 73 is tightly fitted with the inner cover body 41. The bottom support 3, the inner cover 4 and the top cover 7 are reliably connected, and the internal threaded hoop 2 is reliably connected with the steel pipe 1, so that the connection position of the protection rope 6 is stable, which can ensure that the protection rope 6 is always hung at a high position to ensure the safety of the construction workers.

[0040] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention.
