Description

Technical Field

[0001] The utility model relates to the technical field of outdoor sports equipment, in particular to an automatic slow-descent device. Background Art

[0002] Existing descent control systems have several shortcomings, particularly in terms of automatically retracting the sling and providing sufficient braking force. Traditional descent control systems often rely on manual control of the sling retraction, which is not only time-consuming and labor-intensive but can also pose safety risks in emergency situations due to improper operation. Furthermore, some existing automatic retraction systems cannot guarantee the proper retraction of the sling if a single spring fails, posing a risk.

[0003] Current descent control devices on the market also have room for improvement in terms of braking. Many fail to provide sufficient braking force to prevent a loss of control during rapid descents. Furthermore, replacing the webbing is often complex and requires tools, which increases the difficulty and time required for maintenance. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an automatic slow-descent device, which connects a flat belt to a spring in a flat belt storage disk and utilizes the elastic potential energy of the spring to achieve automatic retraction of the flat belt, thereby greatly simplifying the management of the flat belt and reducing the need for manual operation; at the same time, by providing a braking mechanism, sufficient braking force can be provided when the user descends, effectively preventing uncontrolled descent.

[0005] In view of this, the present invention provides the following technical solutions:

[0006] An automatic slow-descent device, the device body comprising:

[0007] a flat belt storage disk, wherein the flat belt storage disk is wound around the flat belt, and the axis of the flat belt storage disk is rigidly connected to the inner coil of at least one mainspring, so that when the flat belt is pulled out, the flat belt storage disk can rotate clockwise, thereby driving the mainspring to rotate synchronously and tighten;

[0008] a large gear ring, the large gear ring being provided on the flat belt storage disk and being used for transmitting the rotation of the flat belt storage disk to the brake mechanism through a predetermined transmission ratio;

[0009] A brake mechanism comprising at least two centrifugal blocks, a friction plate, and a brake drum, wherein one end of at least two of the centrifugal blocks is mounted on the pinion connector via a pivot pin, and the other end is connected to a tension spring to provide a reset force;

[0010] The friction plate is mounted on the centrifugal block. When the centrifugal block rotates at high speed, the friction plate can be pressed against the brake drum under the action of centrifugal force to provide braking force.

[0011] Optionally, the pinion connector is connected to the pinion by a rigid connection or a one-way connection, so as to adjust the retraction speed of the flat belt.

[0012] Optionally, the number of the mainsprings is set to two, and the specifications and sizes of the two mainsprings are the same. As a safety redundancy design, even if one mainspring is damaged, the recovery function of the flat belt can still be guaranteed.

[0013] Optionally, the flat belt and the flat belt storage tray are connected via an extension belt provided with a lock buckle, and the lock buckle is used to connect the flat belt and the extension belt and facilitate the replacement of the flat belt.

[0014] Optionally, one end of the extension strap is fixed to the flat belt storage disk, and the other end is provided with a lock. By pulling out the flat belt disassembly pin on the flat belt disassembly port, the connecting lock of the extension strap and the flat belt is pulled out of the flat belt storage disk to facilitate the replacement of the flat belt.

[0015] Optionally, the brake drum is used in conjunction with the centrifugal block, and when the centrifugal block moves outward under the action of centrifugal force, the friction plate is used to press the brake drum, thereby generating braking force.

[0016] Optionally, a hanging point is provided on the side wall of the device body.

[0017] It can be seen from the above technical solutions that the embodiments of the present invention have the following advantages:

[0018] 1. The present invention provides an automatic descent control device that automatically retracts the sling by connecting it to a spring within a sling storage disk. This spring's elastic potential energy allows the sling to be automatically retracted. When the user stops pulling the sling, the spring releases energy, driving the sling storage disk counterclockwise, automatically retracting the sling into the device. This greatly simplifies sling management and reduces the need for manual operation. Furthermore, a braking mechanism, comprising at least two centrifugal weights, friction plates, and a brake drum, provides sufficient braking force during descent. When the sling storage disk rotates at high speed, the centrifugal weights move outward under the action of an external force, and the friction plates press against the brake drum, generating braking force that effectively prevents uncontrolled descents.

[0019] 2. The automatic descending device of the utility model adopts two springs of the same specifications as a safety redundancy design. Even if one spring fails, the other spring can still ensure the normal recovery of the flat belt, greatly improving the safety performance.

[0020] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0029] An automatic descending device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] For easier understanding, see Figures 1 to 5 The present invention provides an embodiment of an automatic descending device, wherein the device body 1 comprises:

[0031] A flat belt storage disk 2, wherein the flat belt storage disk 2 is wound with a flat belt, and its axis is rigidly connected to the inner coil of at least one mainspring 3, so that when the flat belt is pulled out, the flat belt storage disk 2 can rotate clockwise, driving the mainspring 3 to rotate synchronously and tighten;

[0032] a large gear ring 4, the large gear ring 4 being provided on the flat belt storage disc 2 and being used to transmit the rotation of the flat belt storage disc 2 to the braking mechanism through a predetermined transmission ratio;

[0033] The braking mechanism includes at least two centrifugal blocks 7, a friction plate 8, and a brake drum 11. One end of the at least two centrifugal blocks 7 is mounted on the pinion connector 6 via a pivot pin 9, and the other end is connected to a tension spring 10 to provide a reset force;

[0034] The friction plate 8 is mounted on the centrifugal block 7 . When the centrifugal block 7 rotates at high speed, the friction plate 8 can be pressed against the brake drum 11 under the action of centrifugal force to provide braking force.

[0035] The brake drum 11 is used in conjunction with the centrifugal weight 7. When the centrifugal weight 7 moves outward under the action of centrifugal force, the friction plate 8 is used to press the brake drum 11, thereby generating braking force.

[0036] It should be noted that the webbing storage disk 2 is located within the device body 1 and is used to store the webbing. The axis of the webbing storage disk 2 is rigidly connected to the inner ring of at least one mainspring 3. When the webbing is pulled out, the webbing storage disk 2 rotates clockwise, driving the mainspring 3 to rotate synchronously and tighten, providing power for webbing retraction. A large ring gear 4 is mounted on the webbing storage disk 2. Its function is to transmit the rotation of the webbing storage disk 2 to the brake mechanism through a predetermined transmission ratio, thereby improving the efficiency of the brake mechanism and ensuring timely and sufficient braking force when the webbing is pulled out. The brake mechanism includes at least two centrifugal weights 7, friction pads 8, and a brake drum 11. One end of the at least two centrifugal weights 7 is mounted to the pinion connector 6 via a pivot pin 9, and the other end is connected by a tension spring 10, which provides a return force for the centrifugal weights 7. The friction pads 8 are mounted on the centrifugal weights 7. When the centrifugal weights 7 rotate at high speed, the centrifugal force presses the friction pads 8 against the brake drum 11, thereby providing braking force.

[0037] In some embodiments, the pinion 5 is connected to the pinion connector 6 by a rigid connection or a one-way connection to facilitate adjusting the retraction speed of the flat belt.

[0038] It should be noted that the pinion 5 can be connected to the pinion connector 6 by a rigid connection or a one-way connection, so as to ensure that the retraction speed of the flat belt can be adjusted according to actual needs.

[0039] In some embodiments, the number of the mainsprings 3 is set to two, and the specifications and sizes of the two mainsprings 3 are the same.

[0040] It should be noted that the number of the mainsprings 3 is set to two, and the specifications and dimensions of the two mainsprings 3 are the same. As a safety redundancy design, even if one mainspring 3 is damaged, the recovery function of the flat belt can still be guaranteed.

[0041] In some embodiments, the flat belt is connected to the flat belt storage tray 2 via an extension belt with a lock. The lock is used to connect the flat belt to the extension belt and facilitate the replacement of the flat belt. One end of the extension belt is fixed to the flat belt storage tray 2, and the other end is provided with a lock. By pulling out the flat belt disassembly pin 12 on the flat belt disassembly port, the lock connecting the extension belt and the flat belt is pulled out of the flat belt storage tray 2 to facilitate the replacement of the flat belt.

[0042] It should be noted that the webbing is connected to the webbing storage tray 2 via an extension strap with a lock. This design allows the user to easily replace the webbing by pulling out the webbing detachment latch 12 on the webbing detachment port and pulling the extension strap and the lock connecting the webbing out of the webbing storage tray 2, making it easier to replace the webbing.

[0043] In some embodiments, a hanging point 13 is provided on the side wall of the device body 1 .

[0044] It should be noted that the side wall of the device body 1 is provided with a hanging point 13 to facilitate fixing the device at a desired position.

[0045] Working Principle: When the user pulls the webbing, the webbing is pulled from the webbing storage disc 2. The webbing storage disc 2 then rotates clockwise (assuming the rotation direction is correct). Because the axis of the webbing storage disc 2 is rigidly connected to the inner ring of the mainspring 3, the rotation of the webbing storage disc 2 causes the mainspring 3 to rotate synchronously and tighten, storing energy for subsequent webbing recovery. A large ring gear 4 is mounted on the webbing storage disc 2. As the webbing storage disc 2 rotates, the large ring gear 4 also rotates. The large ring gear 4 transmits this rotation to the brake mechanism's pinion 5 through a predetermined transmission ratio. The rotational motion transmitted by the pinion 5 drives the centrifugal weight 7 to rotate at high speed. One end of the centrifugal weight 7 is attached to the pinion connector 6 via a pivot pin 9. The other end is connected to a tension spring 10, which provides the return force for the centrifugal weight 7. As the centrifugal weight 7 rotates at high speed, it is subjected to centrifugal force, causing it to move outward. The friction plate 8 attached to the centrifugal weight then presses against the brake drum 11, generating braking force and slowing the webbing withdrawal. When the user stops pulling the webbing, the mainspring 3 begins to release its previously accumulated energy, driving the webbing storage disc 2 to rotate counterclockwise (assuming the direction), thereby retracting the webbing into the webbing storage disc 2. If the pinion 5 uses a one-way connection, the one-way connection allows the pinion 5 to rotate freely relative to the pinion connecting member 6 during webbing retraction, thereby adjusting the webbing retraction speed.

[0046] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
