DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5The utility model provides a technical solution: a simple template keel anti-falling device, comprising a connecting steel sheet 1, limited steel sheets 2 are fixedly installed on both sides of the connecting steel sheet 1, and the limited steel sheets 2 are symmetrically distributed about the center line of the connecting steel sheet 1. An installation groove 3 is opened inside the limited steel sheet 2, and the installation groove 3 is arranged in a "T"-shaped structure. A fixing bolt 4 is movably connected inside the installation groove 3, and a square keel 5 is fixedly connected to the inner end of the fixing bolt 4. The square keel 5 is connected to the installation groove 3 by the fixing bolt 4. The diameter of the fixing bolt 4 is consistent with the width of the installation groove 3. The design of the above structure enables the top of the square keel 5 to be inserted into the interior of the installation groove 3 through the fixing bolt 4, and the gravity factor of the square keel 5 is used to drive the fixing bolt 4 to be matched with the bottom of the installation groove 3, so as to facilitate the limited connection between the square keel 5 and the limited steel sheet 2, prevent the square keel 5 from falling during the transmission process, and improve the convenience of temporary hanging of the square keel 5.

[0029] A blocking and limiting mechanism 6 is installed on the outer wall of the connecting steel sheet 1 outside the installation groove 3. The blocking and limiting mechanism 6 includes a fixing seat 601 fixedly installed on the outer surface of the connecting steel sheet 1. A movable rod 602 is slidably penetrated inside the fixing seat 601. A baffle 603 is fixedly installed at the bottom end of the movable rod 602. A spring 604 is sleeved on the surface of the movable rod 602 between the baffle 603 and the fixing seat 601. The baffle 603 is telescopically connected to the fixing seat 601 through the spring 604. The bottom ends of the baffle 603 are obliquely arranged on both sides. The design of the above structure enables the fixing bolt 4 to be driven by the strong squeezing of the through keel 5 during the process of inserting the fixing bolt 4 into the installation groove 3. The inclined surface of the baffle 603 is compressed, so that the baffle 603 squeezes the spring 604, and drives the movable rod 602 to slide in the internal limit position of the fixed seat 601 to improve stability, so that when the baffle 603 rises, the fixing bolt 4 can be inserted into the installation groove 3 for limiting. At the same time, when taking it out, the strong pulling of the square keel 5 and the fixing bolt 4 can force the baffle 603 to rise for disassembly. When the fixing bolt 4 is clamped in the installation groove 3, the spring 604 can push the baffle 603 to reset, thereby blocking the disassembly route of the fixing bolt 4, thereby preventing the fixing bolt 4 and the square keel 5 from sliding out easily, thereby improving the anti-fall effect.

[0030] A fixing block 7 is fixedly installed on the outer side of the limiting steel sheet 2, and an anti-fall hook assembly 8 is fixedly installed on the top of the fixing block 7. The anti-fall hook assembly 8 includes a fixing hook 801 fixedly installed on the top of the fixing block 7, a sleeve 802 is fixedly installed on the top of the fixing hook 801, and a movable hook 803 is slidably connected inside the sleeve 802. A positioning groove 804 is provided inside the movable hook 803, and the positioning grooves 804 are provided at equal intervals inside the movable hook 803. A threaded sleeve 805 is fixedly inlaid inside one end of the sleeve 802, and a positioning bolt 806 is penetrated through the internal thread of the threaded sleeve 805. The positioning bolt 806 is connected to the movable hook 803 through the positioning groove 804. The design of the above structure enables the movable hook 803 to slide inside the sleeve 802, thereby adjusting the distance between the movable hook 803 and the fixed hook 801, which is conducive to the distance between the two to adapt to the width of the hanging external frame. After the sliding adjustment of the movable hook 803, the positioning bolt 806 can be rotated to extend it inside the threaded sleeve 805 and engage with the corresponding positioning groove 804 on the movable hook 803, which is conducive to fixing the adjusted movable hook 803.

[0031] Working principle: When using this simple template keel anti-fall device, Figure 1-5 As shown, first, according to the width of the outer frame at the hanging position, the movable hook 803 is pulled to make it slide inside the sleeve 802, so as to adjust the distance between the movable hook 803 and the fixed hook 801 to adapt to the width of the outer frame. When the adjustment is completed, the positioning bolt 806 is rotated to make it pass through the threaded sleeve 805 and form an engagement with the corresponding positioning groove 804, so as to complete the adjustment and positioning of the movable hook 803. Then, multiple groups of fixed hooks 801, sleeves 802 and movable hooks 803 are hung on the outer frame. Then, when the square keel 5 is transferred, the square keel 5 and the top fixing bolt 4 are vigorously inserted into the interior of the installation groove 3 along the opening of the installation groove 3. During the insertion process The fixing bolt 4 will squeeze the baffle 603, so that the baffle 603 drives the movable rod 602 to rise inside the fixing seat 601. At this time, the fixing bolt 4 can enter the interior of the installation groove 3 and complete the limiting connection between the square keel 5 and the limiting steel sheet 2. When the square keel 5 is disassembled, the square keel 5 and the fixing bolt 4 are lifted so that the fixing bolt 4 is aligned with the opening of the installation groove 3. Then, the square keel 5 is pulled vigorously to drive the fixing bolt 4 to slide out of the opening of the installation groove 3, and the baffle 603 is squeezed to shrink during the sliding process, thereby realizing the disassembly of the square keel 5 and the fixing bolt 4, so as to facilitate the subsequent transfer and temporary hanging work.
