Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] In order to make the person skilled in the art better understand the utility model scheme, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0027] The utility model provides a kind of hanging bell anti-falling accessory, which comprises fastener 3, and the top holding piece 4 is extended in the outer periphery of fastener 3, and the lead-in part 31 is provided at the end of fastener 3 away from the top holding piece 4, and the lead-in part 31 is used to assist fastener 3 to carry out plug-in work, in addition, the side of top holding piece 4 close to lead-in part 31 has pressure surface, and the pressure surface is gradually away from lead-in part 31 while being away from the axis of fastener 3, and the extension length of the pressure surface formed by top holding piece 4 exceeds the port size of target cavity, so that the pressure surface can be interference fit with target cavity, and the pressure surface of top holding piece 4 is in abutment with target cavity port, to guide top holding piece 4 into target cavity, so that the clamping process of fastener 3 is more moderate.

[0028] Please refer to the drawings in the description Figure 1The fastener 3 is coaxially connected with the lead-in part 31, the length of the fastener 3 is less than the depth of the inner cavity of the bell 1, the fastener 3 is fully inserted into the hanging rope 2, the connection between the fastener 3 and the hanging rope 2 is stable, the lead-in part 31 is arranged at the end of the fastener 3 away from the top holder 4, the lead-in part 31 is used for assisting the fastener 3 to be inserted into the to-be-fixed part, and the fastener 3 is connected with the to-be-fixed part, preferably, the fastener 3 is a cylinder, the lead-in part 31 is a cone, the taper direction of the lead-in part 31 is away from the side of the top holder 4, the size of the tapered end of the lead-in part 31 is smaller, and the lead-in part 31 is more easily inserted into the seam of the to-be-fixed part, further, in order to prevent the tapered end of the lead-in part 31 from being sharp and scratching a worker or a user, a round corner is arranged at the tapered end of the lead-in part 31, similarly, the top holder 4 is tapered at the end away from the fastener 3, so that the top holder 4 is horn-shaped, and the tapered end of the top holder 4 is also provided with a round corner, so that the long sharp end is prevented from extending to the outside of the to-be-fixed part and scratching the user.

[0029] Preferably, the top holder 4 is at least two, and each top holder 4 is uniformly arranged on the outer periphery of the fastener 3, so that the abutting point positions of the fastener 3 and the to-be-fixed part are increased, and the clamping stability of the top holder 4 is ensured.

[0030] The utility model also provides a bell anti-falling structure, please refer to the attached drawings of the description Figure 1 to the attached Figure 4The hanger anti-falling structure comprises the hanger anti-falling accessory and a hanger 1 having an inner cavity in which the hanger rope 2 is inserted, and the hanger rope 2 is provided with the fastener 3, and the outer wall of the fastener 3 extends the top holder 4, and the side wall of the top holder 4 abuts against the inner wall of the hanger 1. It should be noted that the top holder 4 is arranged at a certain angle with the fastener 3, and the included angle between the top holder 4 and the fastener 3 is directed to the inner cavity of the hanger 1, so that the pressure bearing surface is inclined away from the introduction part 31, and the hanger rope 2 can slip on the fastener 3, and when the hanger rope 2 slips to the connection part of the top holder 4 and the fastener 3, the hanger rope 2 is locked by the top holder 4. In addition, the top holder 4 is also curved towards the axis direction of the fastener 3, so that the pressure bearing surface is in an arc shape, the process of abutting the top holder 4 against the port of the hanger 1 is eased, the area of the side wall of the top holder 4 that can be attached to the inner cavity of the hanger 1 is increased, and the friction between the top holder 4 and the inner cavity of the hanger 1 is improved. In the process of fixing the hanger 1 and the hanger rope 2, the hanger rope 2 is first inserted into the inner cavity of the hanger 1, the introduction part 31 of the fastener 3 is inserted into the hanger rope 2, and the insertion direction is directed to the end part of the hanger rope 2, so that the top holder 4 on the side wall of the fastener 3 abuts against the port of the hanger 1, pushes the fastener 3, and the top holder 4 is deformed on the side wall and reduces the included angle with the fastener 3, and then extends into the inner cavity of the hanger 1. When there is an external force pulling the hanger 1 and the hanger rope 2, the hanger rope 2 is locked in the inner cavity of the hanger 1 by the top holder 4, and the hanger rope 2 drives the fastener 3 to move to the port side of the hanger 1, so that the top holder 4 has a restoring tendency, the top holder 4 increases the pressure on the inner cavity of the hanger 1, thereby increasing the friction between the top holder 4 and the hanger 1, and ensuring that the hanger rope 2 and the hanger 1 can be stably connected.

[0031] Preferably, the end part of the hanger rope 2 is provided with a plastic-coated rope head 21, which is a cylinder and is arranged on the outer periphery of the end part of the hanger rope 2. The outer wall of the plastic-coated rope head 21 is attached to the inner cavity of the hanger rope 2. The plastic-coated rope head 21 is made of hard plastic, which facilitates the insertion of the hanger rope 2 into the inner cavity of the hanger 1. In addition, the hanger rope 2 can be two wire ropes twisted together to form a spiral shape. The fastener 3 is connected to the hanger rope 2, and the introduction part 31 extends into the inner cavity of the plastic-coated rope head 21. It should be noted that after the fastener 3 is connected to the plastic-coated rope head 21, the top holder 4 is located outside the plastic-coated rope head 21, and the length of the plastic-coated rope head 21 is less than the depth of the inner cavity of the hanger 1, that is, after the end surface of the plastic-coated rope head 21 is attached to the bottom surface of the inner cavity of the hanger 1, a part of the inner wall near the port side of the inner cavity of the hanger 1 is reserved for abutting against the top holder 4, so as to avoid the plastic-coated rope head 21 being the same length as the inner cavity of the hanger 1. When the top holder 4 is clamped in the inner cavity of the hanger 1, the plastic-coated rope head 21 is abutted, the abutted load exceeds the bearing range of the plastic-coated rope head 21 made of plastic material, the structure of the plastic-coated rope head 21 is damaged, and the service life of the hanger anti-falling structure is reduced.

[0032] Further, the edge of the plastic-coated rope head 21 extending into the inner cavity of the bell 1 can be provided with a chamfer. The chamfer reduces the diameter of the end of the plastic-coated rope head 21. The chamfer forms an inclined surface that guides the plastic-coated rope head 21 to more easily enter the inner cavity of the bell 1. In addition, the diameter of the plastic-coated rope head 21 can be slightly larger than the diameter of the inner cavity of the bell 1. The plastic-coated rope head 21 and the bell 1 are in interference fit, which increases the friction between the plastic-coated rope head 21 and the inner cavity of the bell 1. This prevents the plastic-coated rope head 21 from sliding towards the side of the port of the bell 1, and the fastener 3 from extending into the inner cavity while also extending into the interior of the plastic-coated rope head 21, which would damage the structure of the plastic-coated rope head 21 and affect the fixing effect of the fastener 3.

[0033] Please refer to the drawings in the specification Figure 2 The top holder 4 can be two, each top holder 4 is symmetrically distributed on both sides of the axis direction of the fastener 3, each top holder 4 is arranged at a certain angle with the fastener 3, and the included angle between the two top holders 4 points to the inner cavity of the bell 1. It should be noted that the arc-shaped side wall of each top holder 4 corresponding to the inner wall of the bell 1 is called the pressure bearing surface, the distance between the two pressure bearing surfaces gradually increases away from the end of the guide-in portion 31, and the minimum distance between the pressure bearing surfaces is less than the diameter of the port of the bell 1, and the maximum distance is greater than the diameter of the port of the bell 1. During the process of inserting the fastener 3 into the inner cavity of the bell 1, the distance between the pressure bearing surfaces corresponding to the port of the bell 1 gradually increases until the pressure bearing surfaces abut against the port of the bell 1. At this time, the pushing force on the fastener 3 is increased, causing the arc-shaped pressure bearing surface to deform and reduce the distance between the pressure bearing surfaces. At the same time, the port of the bell 1 clamps the top holder 4, reducing the included angle between the two top holders 4 and further reducing the distance between the pressure bearing surfaces, until the top holder 4 can completely enter the inner cavity of the bell 1.

[0034] In an embodiment of the present application, the lifting rope 2 is fixed to the bell 1 by the fastener 3. When an external force pulls the bell 1 and the lifting rope 2, the lifting rope 2 passing through the fastener 3 is clamped on the top holder 4 abutting against the inner wall of the bell 1. The lifting rope 2 drives the fastener 3 to move towards the side of the port of the bell 1, the fastener 3 drives the top holder 4, and the inner wall of the bell 1 generates a friction force on the top holder 4 in the opposite direction of the movement of the top holder 4. This friction force hinders the movement of the fastener 3 while driving the top holder 4 to return to its original state, i.e., the top holder 4 has a tendency to increase the included angle with the fastener 3. The pressure bearing surface of the top holder 4 exerts an increased pressure on the inner wall of the bell 1, and the friction between the top holder 4 and the bell 1 increases. The connection between the fastener 3 and the bell 1 is more secure, and the bell 1 is less likely to separate from the lifting rope 2.

[0035] Preferably, the length of the fastener 3 is less than the length of the plastic-coated rope head 21, ensuring that after the fastener 3 completely extends into the plastic-coated rope head 21, the guide-in portion 31 of the fastener 3 does not abut against the end face of the plastic-coated rope head 21. The fastener 3 still has sufficient movement distance to push each top holder 4 into the inner cavity of the bell 1.

[0036] In addition, the top holder 4 can be a hollow structure, the wall thickness of the top holder 4 is smaller than the wall thickness of the bell 1, the yield strength of the top holder 4 is reduced, so that the top holder 4 is not enough to cause damage to the side wall of the bell 1 during the process of inserting the fastener 3, and the top holder 4 is more easily deformed, so that the process of inserting the fastener 3 is more easy, and it should be noted that the top holder 4 is made of an alloy material, such as aluminum alloy or zinc alloy, and during the process of pulling the fastener 3 out of the bell 1, the top holder 4 can generate enough extrusion force on the side wall of the bell 1 to limit the separation of the plastic coated rope head 21 from the bell 1.

[0037] In an embodiment of the present application, the top holder 4 and the fastener 3 are integrally formed zinc alloy parts, the bell anti-falling part inserted into the bell 1 through the bell rope 2 by a press to achieve interference fit, and the top holder 4 and the bell 1 are extruded to increase the friction force to provide the anti-falling effect by deforming the physical properties of the material.

[0038] Preferably, the side wall of the end portion of the bell 1 is tapered to the port, and the edge of the port of the bell 1 is provided with a round corner, so that the abutting process of the top holder 4 and the port of the bell 1 is more gentle, and the bell 1 or the top holder 4 is prevented from being damaged by knocking, and in addition, an arc chamfer is provided at the connection between the top holder 4 and the fastener 3, so that when the top holder 4 is extruded by the inner wall of the bell 1, the load distribution at the connection between the top holder 4 and the fastener 3 is more uniform, and the load strength of the top holder 4 is increased.

[0039] It should be noted that in the present specification, the relationship terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any actual relationship or order between the entities.

[0040] The principle and implementation mode of the present application are described by using specific examples, and the above description of the embodiments is only used to help understand the method and its core idea. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the principle of the present application, the present application can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the present application.
