DETAILED DESCRIPTION

[0022] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0023] As shown in Figures 1 to 4 , Figure 7 and Figure 8 , the frame profile 1 is an aluminum profile, which is commonly used to form an aluminum frame or is arranged on a device such as a hoist as a pull rod. In order to reduce weight, the frame profile 1 is usually hollow. The protective net includes four pipes 2 that form a rectangle, and metal wire 3 is arranged between the opposite pipes to form a mesh structure. The present embodiment discloses how to quickly disassemble and assemble the pipes 2 of the protective net and the frame profile 1. The upper surface of the frame profile 1 abuts against the lower surface of the pipes 2. The abutting surface of the frame profile 1, i.e., the upper surface, is provided with a rectangular opening 4. The opening 4 is connected to the hollow inner cavity of the frame profile 1. The vertical surface of one side of the frame profile 1 is provided with a first slot 5 that penetrates the side surface. The length direction of the first slot 5 is the vertical direction. The pawl 6 includes a horizontal pressing portion 7, a vertical connecting portion 8 and a mounting portion 9 that are connected in sequence. The horizontal pressing portion 7, the vertical connecting portion 8 and the mounting portion 9 are integrally formed. The horizontal pressing portion 7 is vertically connected to the vertical connecting portion 8. The horizontal pressing portion 7 has a horizontal lower surface that can be used to press the pipes 2. The vertical connecting portion 8 has a vertical surface that can abut against one side of the pipes 2 and is used to connect the horizontal pressing portion 7 and the mounting portion 9. The mounting portion 9 is in the shape of an inverted L and has a vertical mounting surface. The first mounting hole 10 that penetrates the mounting surface of the mounting portion 9 is arranged. The pawl 6 is vertically placed into the opening 4 so that the mounting portion 9 enters the frame profile 1 and the horizontal pressing portion 7 is outside the frame profile 1. The position of the first mounting hole 10 corresponds to the position of the first slot 5. The first bolt 11 penetrates the first slot 5 and the first mounting hole 10 to connect the pawl 6 and the frame profile 1. The relative movement state between the pawl 6 and the frame profile 1 is adjusted by the tightness of the first bolt 11. The first bolt 11 can be displaced up and down along the length direction of the first slot 5 in the first slot 5. That is, after the pawl 6 is connected to the frame profile 1, the pawl 6 can be vertically displaced relative to the frame profile 1 in a limited manner. The limited displacement length is determined by the length of the first slot 5. At this time, the horizontal pressing portion 7 is located above the upper surface of the pipes 2. The position of the first mounting hole 10 moves synchronously with the first bolt 11. Figure 7As shown, when the position of the first mounting hole 10 corresponds to the first position of the first strip-shaped hole 5, i.e. the uppermost position, the pipe 2 is in abutment with the frame profile 1, the horizontal pressing part 7 is located immediately above the upper surface of the pipe 2 and is arranged at intervals, the pipe 2 can be adjusted in position or removed from the abutment state with the frame profile 1, as shown in FIG. 2B. Figure 8 As shown, when the position of the first mounting hole 10 corresponds to the second position of the first strip-shaped hole 5, i.e. the lowermost position, the horizontal pressing part 7 moves vertically downward and abuts against the upper surface of the pipe 2, the pipe 2 is pressed against the frame profile 1 and the first bolt 11 is tightened, the relative fixation between the pipe 2 and the frame profile 1 is completed, if it is desired to release the relative fixation between the pipe 2 and the frame profile 1, the first bolt 11 is unscrewed, the clamping jaw 6 is moved upward relative to the frame profile 1, at this time the horizontal pressing part 7 is spaced apart from the upper surface of the pipe 2 and is arranged at intervals, the pipe 2 can be moved out of the frame profile 1. The horizontal projection area of the horizontal pressing part 7 on the frame profile 1 is greater than the horizontal projection area of the opening part 4 on the frame profile 1, that is, the surface area of the horizontal pressing part 7 is greater than the surface area of the opening part 4, so as to ensure that the horizontal pressing part 7 does not completely fall into the opening part 4, and to prevent the clamping jaw 6 from accidentally falling into the opening part 4 of the frame profile 1.

[0024] In some embodiments, as shown in FIG. 1A, Figures 1 to 8 As shown, a baffle 12 is further included, the baffle is a rectangular metal sheet, the plane of the baffle 12 is arranged vertically, the baffle 12 is provided with a second mounting hole 13 penetrating therethrough, the second mounting hole 13 is adapted to the size of the first bolt 11, the second mounting hole 13 can be arranged eccentrically relative to the baffle 12, the baffle 12 is arranged on the side of the frame profile 1 provided with the first strip-shaped hole 5, and the position of the second mounting hole 13 corresponds to the position of the first mounting hole 10, the first bolt 11 passes through the second mounting hole 13, the first strip-shaped hole 5 and the first mounting hole 10 in sequence, so as to connect the frame profile 1, the clamping jaw 6 and the baffle 12, and the baffle 12 can be rotated vertically about the position of the second mounting hole 13. As shown in FIG. 1A, Figure 7 As shown, when the baffle 12 is located at the third position, i.e. the long side of the baffle 12 is in a horizontal position, the height of the baffle 12 is lower than the upper surface of the frame profile 1, i.e. the baffle 12 does not interfere with the pipe 2 moving out of or into the upper surface of the frame profile 1 in the horizontal direction, as shown in FIG. 2B. Figure 8As shown, when the baffle 12 is in the fourth position, that is, the long edge of the baffle 12 is in the vertical position, the height of the baffle 12 is higher than the upper surface of the frame profile 1, at this time the pipe 2 on the upper surface of the frame profile 1 is limited by the baffle 12 on one side and the vertical surface of the vertical connecting part 8 on the other side, so that it cannot move in the horizontal direction, avoiding the problem of easy shaking of traditional single-point fixing. The claw 6 cooperates with the baffle 12 to realize multiple limiting in the vertical and horizontal directions, improving the reliability of the fixing. The rotatable state of the baffle 12 is also realized by the tightening state of the first bolt 11. When the first bolt 11 is in the untightened state, the positions of the baffle 12 and the claw 6 relative to the frame profile 1 can be adjusted. After the positions are determined, the first bolt 11 is tightened, and the fixing is completed.

[0025] In some embodiments, as shown in Figures 3 to 8 The mounting part 9 includes a third mounting hole 14, which is a horizontal through hole. The third mounting hole 14 is arranged at the same horizontal height as the first mounting hole 10 and is spaced apart. The frame profile 1 is provided with a second slot 15 at a position corresponding to the third mounting hole 14. The length direction of the second slot 15 is the vertical direction. The second slot 15 is also arranged at the same horizontal height as the first slot 5 and is spaced apart. The baffle 12 is provided with an arc-shaped hole 16 passing through at a position corresponding to the third mounting hole 14. The shape of the arc-shaped hole 16 is a 90-degree arc. A second bolt 17 passes through the arc-shaped hole 16, the second slot 15, and the third mounting hole 14. When the baffle 12 rotates around the second mounting hole 13, the arc-shaped hole 16 will displace relative to the second bolt 17. The two ends of the arc-shaped hole 16 limit the rotation angle of the baffle 12. At the same time, the first bolt 11 and the second bolt 17 act on the claw 6 and the baffle 12 at the same time, which can further improve the stability.

[0026] In some embodiments, as shown in Figures 3 to 8 The horizontal pressing part 7 has a pressing claw 18 extending downward at an end away from the vertical connecting part 8. When the first mounting hole 10 corresponds to the second position of the first slot 5, that is, the claw 6 presses the pipe 2 against the frame profile 1, the pressing claw 18 limits the horizontal side of the pipe 2 to prevent it from coming out in the horizontal direction.

[0027] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 7 and Figure 8 The frame profile is provided with a third slot 19. The third slot 19 is arranged at the same horizontal height as the first slot 5 and the second slot 15 along the length direction of the frame profile 1 and is equally spaced. The third slot 19 provides redundancy for the movement of the claw 6 relative to the length direction of the frame profile 1. That is, the first bolt 11 and the second bolt 17 can be inserted into the second slot 15 and the third slot 19 respectively, which can complete the fine adjustment of the movement of the claw 6 in the length direction of the frame profile 1, and adapt to more installation requirements.
