[0032] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The terms "left front, right front, left rear, right rear" are used to describe positional relationships and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0034] like Figure 1 The clip-on lock is used to connect the boom. The installation of the boom specifically refers to: installing a vertically placed rod on a high-altitude bracket or frame or a tower crane or other large fixed equipment, which is mostly arranged in a screw structure, and its horizontal spacing is uniformly arranged at 1.2m. The clip-on lock applied in this case consists of three structures, specifically a first body 1 and a second body 2, a connector 3 for connecting the lifeline and a locking assembly, which is used to complete the fixation of the high-altitude lifeline and the boom, as described below:

[0035] First, the first body 1 and the second body 2 are both made of tensile and compressive materials to meet the rigidity requirements, for example, they are made of metal or alloy materials. Its shape can be a quadrilateral or polygonal structure, such as a rectangle or square or hexagon or other shapes, preferably a rectangular structure. The first body 1 and the second body 2 serve as carriers of the connector 3 and the locking assembly, and a receiving portion 4 for accommodating the suspension rod is formed at corresponding positions on the facing surfaces of the first body 1 and the second body 2. The receiving portion 4 is used to place the suspension rod of the current national standard size, that is, the first body 1 and the second body 2 have arc grooves at corresponding positions. The setting of the arc groove can be completed by using a stamping device in a mold. For example, the suspension rods of 10 and 12 calibers are opened in the vertical direction. The number of the receiving portions 4 can be one, two or more, preferably two, to accommodate suspension rods of 10 and 12 calibers (10mm or 12mm) respectively.

[0036] The connecting member 3 passes through one end of the first body 1 and the second body 2. For example, the first body 1 and the second body 2 are arranged in a rectangular structure, and arc-shaped lugs (semicircular lugs) can be formed on both sides of the long sides of the first body 1 and the second body 2, respectively. The connecting member 3 rotatably connects the first body 1 and the second body 2 by passing through the arc-shaped lugs, or the first body 1 and the second body 2 can be rotatably connected as a whole in the manner of passing through bearings, with the connecting member 3 as the axis. After the connecting member 3 is passed through, protruding ends are left at both ends or one end, and the protruding ends are used to connect the high-altitude lifeline. In this way, the installation of the high-altitude lifeline and the suspension rod can be simplified, and the disassembly is convenient.

[0037] One end of the locking assembly is rotationally connected to the first body 1 or the second body 2 at one end of the principle connecting member 3, and rotates with the first body 1 or the second body 2 as the axis, and the other end is used to lock with the second body 2 or the first body 1. It should be pointed out that: one end of the first body 1 or the second body 2 is rotationally connected to the locking assembly, and the positions are relative. For example, one end of the locking assembly is rotationally connected to the first body 1, and the other end must be locked with the second body 2. Conversely, one end of the locking assembly is rotationally connected to the second body 2, and the other end is locked with the first body 1. The function of the rotational connection setting of one end of the locking assembly with the first body 1 is that the connecting member 3 connects the first body 1 and the second body 2 rotationally with the connecting member 3 as the axis. Considering the convenience of placing the suspension rod into the accommodating portion 4, the other body non-rotatably connected to the locking assembly is then buckled, and the first body 1 and the second body 2 are locked by the locking assembly to form a clamping force on the suspension rod.

[0038] As an optional embodiment, the connector 3 passes through the first body 1 and the second body 2 and has protruding ends at both ends, one of which is used to connect the lifeline. The purpose of this structural design is to save the use of materials and save costs. If there are protruding ends at both ends, one end is connected to the high-altitude lifeline, and the other end can be a limit end or a reinforcement end to prevent the connector 3 from falling off the first body 1 and the second body 2.

[0039] Further structural setting, the connector 3 includes an integrally arranged limiting section 31, a free section 32 and a lifeline connecting section 33, wherein: the protruding end at one end of the connector 3 is the limiting section 31, and the setting of the limiting section 31 can be adopted, for example, the size of the limiting section 31 of the integral connector 3 is thickened, or the connector 3 passes through the first lug 11 and the second lug 21, and the limiting section 31 is stamped by stamping during manufacturing, so that the limiting section 31 undergoes a geometric change, and the stamped limiting section 31 can be stuck on one side of the opening of the arc-shaped lug, and the protruding end at the other end is the lifeline connecting section 33. In the natural state, the free section 32 can freely pass through the first body 1 and the second body 2, that is, the size of the hole is larger than the size of the free section 32, and the limiting section 31 is used to limit the distance that the free section 32 passes through.

[0040] As an optional implementation, a clamping piece 34 for clamping the lifeline is provided between the free section 32 and the lifeline connection section 33. The high-altitude lifeline connection section 33 is provided in a spiral structure. Generally, there are two on-site construction installation methods. One is that the high-altitude lifeline passes through the connection section 33 provided with a spiral structure, and the spacing between the suspension rods is 1.2m. Each suspension rod is equipped with the lock. The installation of the high-altitude safety line is as follows: the high-altitude lifeline passes through the lifeline connection section 33 of each lock in turn to complete the fixation of the lifeline as a whole; the second is that when the safety lifeline needs to be wound around part of the connection section 33 to form a fixation with the suspension rod, the binding method is not only troublesome to operate, but also time-consuming. Therefore, a clamping piece 34 is provided between the free section 32 and the lifeline connection section 33, and the safety lifeline is clamped on the clamping piece 34 by winding, which is more convenient for high-altitude operation.

[0041] As an optional embodiment, the first lug 11 and the second lug 21 for the connector 3 to pass through are respectively arranged at corresponding positions on both sides of one end of the first body 1 and the second body 2. This structural arrangement can reduce the consumables of the first body 1 and the second body 2 and save economic costs. During the process, the connector 3 passes through one end of the first body 1 and the second body 2, and the short side length of the first body 1 is less than the short side length of the second body 2, so that the first lug 11 and the first lug 21 can form a straight line structure, which is convenient for the connector 3 to pass through.

[0042] As an optional embodiment, the locking assembly includes a rotating member 41 and a locking member 42, wherein the rotating member 41 is a bolt and the locking member 42 is a nut, wherein one end of the rotating member 41 is rotatably connected to one end of the second body 2, and the other end can freely pass through the first body 1 and connect to the locking member 42. After the hanger is placed in the accommodating portion 4, the first body 1 and the second body 2 are locked by the locking member 42 to clamp the hanger.

[0043] Furthermore, a groove 13 (the groove 13 is a U-shaped structure) and a third lug 22 for placing the rotating member 41 are respectively arranged at one end of the first body 1 and the second body 2 away from the connecting member 3, a fixed shaft is installed between the third lug 22, and the rotating member 41 is connected to the fixed shaft in a rotating manner, that is, one end of the rotating member 41 is hinged to the third lug 22. When in use, after placing the suspension rod, the rotating member 41 is rotated in the direction of the groove 13, and after the rotating member 41 is placed in the groove 13, the locking member 42 is rotated to complete the locking of the suspension rod.

[0044] As an optional embodiment, a hole 100 for connecting a hanging rope lock is provided on the first body 1 or the second body 2. The hole 100 is arranged near the groove 13 to prevent the lock buckle from falling off. The hanging rope lock is a prior art, one end of which is connected to the hole and the other end is connected to the suspension rod. When working at high altitude, the falling of an object may cause hidden dangers, which may easily cause death or damage public facilities.

[0045] As an optional implementation, an anti-skid groove 200 is provided on the first body 1 and / or the second body 2. The anti-skid groove 200 is horizontally arranged and made by a stamping process to increase the clamping force on the suspension rod.

[0046] Furthermore, protruding arc-shaped surfaces 200 are formed on both sides of the long sides of the first body 1. The function of the arc-shaped surface 300 is to reduce the loss caused by collision with other components during storage and to facilitate taking and placing. The length of the arc-shaped surface 200 is one-third to one-half of the length of the first body 1, and is preferably arranged near the groove 13.

[0047] According to the structural setting of this technical solution, the first body 1 and the second body 2 and their connecting parts are made of 70# steel, with engineering diameters of 5.00, 5.50 and 10.00 mm. They are made of a metal alloy of carbon, manganese silicon and gong. After tensile and stiffness tests, they meet the engineering design specifications of 1 ton to 3 tons. The quality inspection unit: Jiangsu Shuigao Steel Wire Products Co., Ltd., and the test report issued has been certified.
