[0030] The overweight alarm device 4 is arranged in the cavity two 12, and the bottom of the overweight alarm device 4 is connected to the universal bearing 5. The universal bearing 5 includes a bearing seat 29 and a shaft seat 30. The shaft seat 30 A bearing pendulum 31 is connected to the bottom, the hanging hook 6 is movably connected in the bearing pendulum 31, a turntable 32 is arranged on the top of the hanging hook 6, and the positions corresponding to the bearing pendulum 31 at the bottom of the turntable 32 are respectively provided A number of sliding grooves 33, and a number of sliding beads 34 are arranged in the sliding grooves 33.
[0031] In one embodiment, for the cavity 11 described above, a plurality of fixing posts 35 are fixedly connected to the inner wall of the cavity 11, and the chain 22 is arranged on it. It is ensured that the position of the chain 3 during sliding does not change, and the normal operation of the sliding work is ensured.
[0032] In one embodiment, for the above-mentioned steel wire protective sleeve 19, the steel wire protective sleeve 19 is a polymer rubber sleeve. The use of polymer rubber makes the steel wire protective sleeve 19 more durable and effectively protects the steel wire rope 20.
[0033] In one embodiment, for the tooth 18 and the tooth block 14, the surfaces of the tooth 18 and the tooth block 14 are coated with an anti-wear layer. Effectively reduce the damage to parts caused by friction and greatly increase the service life of parts.
[0034] In an embodiment, for the movable wheel 27 described above, a number of balls 28 are clamped on the outer surface. As a result, the resistance of the chain 3 in use is lower and the sliding movement is smoother.
[0035] In one embodiment, for the above-mentioned overweight alarm device 4, the overweight alarm device 4 uses a Hall element inside.
[0036] In one embodiment, for the bearing seat 29 and the shaft seat 30 described above, an anti-wear pad 36 is provided between the bearing seat 29 and the shaft seat 30. The use of the anti-wear pad 36 can effectively increase the service life of the universal bearing, and the universal bearing is more convenient in use.
[0037] In one embodiment, for the hook 6 described above, the hook head of the hook 6 is provided with a raised point 37.
[0038] In one embodiment, for the above-mentioned bearing pendulum 31, a movable baffle 38 is movably connected to the bearing pendulum 31, and a fixed spring clamp 39 is provided between the movable baffle 38 and the hook 6 . The movable baffle plate is effectively fixed, so that the goods will not fall off during use, which increases safety.
[0039] In an embodiment, for the movable baffle 38 described above, the end of the movable baffle 38 away from the bearing pendulum 31 is clamped on the raised point 37. The movable baffle can be effectively blocked, and the opening of the movable baffle can prevent the goods from being scattered and causing accidents.
[0040] In summary, with the above technical solution of the present invention, when in use, the chain 3 enters from the chain outlet 22 at one end and exits from the chain outlet 22 at the other end. The soft bottom pad 16 Connected to the fixed post 35, the tooth block 14 engages the tooth 18, and the engagement of the fixed post 35 and the tooth makes the chain 3 difficult to fall off, which increases the safety of the present invention. The steel wire rope 20 Set in the steel wire protective sleeve 19, sliding through the gears, not directly sliding through the steel wire rope 20, effectively reducing the wear of the steel wire, and the combination of a plurality of the steel wire ropes 20 increases the bearing capacity of the present invention. For weight and durability, the anti-block roller 23 is added to effectively reduce the resistance of the chain 3 when sliding, making the chain 3 slide more labor-saving, and the sliding bead 34 is arranged on the top of the hook 6 , The hook 6 can be used in different directions, making it more convenient to use, and the overweight alarm device 4 is provided on the universal bearing 5 to effectively control the weight of the lifted goods, and placing overweight causes safety hazards The addition of the movable baffle 38 on the hook can effectively prevent the goods from falling due to shaking during activation. The present invention reduces the friction on the wire rope by setting the gear rotation, and at the same time, the addition of a protective cover greatly reduces the wire rope At the same time, the weight of the chain is strengthened by multiple steel wire ropes, so that the steel wire rope in use can distribute the weight, effectively reducing the burden of a single wire rope, greatly improving the service life, and the hook can rotate in universal directions, making the The middle is more convenient, and the baffle is added to prevent the goods from falling, which increases the safety.
[0041] The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the present invention. Within the scope of protection.
