Description

Technical Field

[0001] This utility model relates to the field of installation technology of parachute assistive equipment, and specifically to a parachute assistive device. Background Technology

[0002] In skydiving and related operations, an altimeter is an indispensable piece of auxiliary equipment. It provides skydivers with real-time altitude data, playing a decisive role in safe parachute deployment and the smooth progress of the entire skydiving process.

[0003] From a wearing advantage perspective, existing altimeters utilize the relatively abundant muscles in the upper arm, which offer greater stability in range of motion compared to the wrist. Fixing the altimeter here effectively reduces swaying and displacement caused by frequent limb movements during skydiving, providing a more stable reading environment for the skydiver. Simultaneously, the relatively flat surface of the upper arm facilitates the installation of larger, more complex altimeters, allowing for the inclusion of more sensors and precision components to achieve richer functionality.

[0004] In existing technologies, altimeters are typically secured with wristbands or straps. Wristbands are generally used to fix the altimeter to the wrist area. However, wristbands are usually designed based on wrist circumference, resulting in relatively fixed sizes. The circumference of the upper arm, however, varies much more widely. This makes it difficult to fit the different upper arm sizes of skydivers using wristbands. For those with thicker upper arms, the wristband may be too tight, causing discomfort and even affecting blood circulation. For those with thinner upper arms, the wristband may be too loose, making the altimeter prone to wobbling and shifting, and unable to be stably fixed to the upper arm. Furthermore, the wristband fixing method is relatively simple, relying mainly on elasticity or buckles for fixation. During a skydive, the skydiver makes significant movements and is subjected to strong airflow, which can cause the wristband to loosen, affecting the stability of the altimeter installation.

[0005] As for the method of securing the altimeter with straps, the altimeter is usually attached to the upper arm with straps. However, during a skydive, the skydiver's movements are large and they are subjected to strong airflow. With the influence of movement and airflow, the straps may gradually loosen, thus affecting the stability of the altimeter's installation.

[0006] Therefore, we propose a parachute assist device. Utility Model Content

[0007] This invention proposes a parachute assist device that solves the problem of low stability of altimeters during use in the prior art.

[0008] The technical solution of this utility model is as follows: A parachute assist device includes an altimeter, a fixed base, mounting slots, straps, a take-up roller, a rotating mechanism, and a positioning mechanism. The fixed base is fixedly disposed on the side wall of the altimeter. Two first cavities are opened inside the fixed base, and a fixing opening is provided on the inner bottom wall of the first cavity. Two mounting slots are opened on the side wall of the altimeter away from the fixed base. A mounting post is rotatably disposed in the mounting slot. The straps are fixedly disposed on the side wall of the mounting posts. The take-up roller is rotatably disposed in the first cavity. The end of the strap away from the mounting post is fixedly disposed on the side wall of the take-up roller. The rotating mechanism is disposed on the take-up roller and is used to drive the take-up roller to rotate. The positioning mechanism is disposed on the fixed base and is used to position the take-up roller.

[0009] Preferably, the rotating mechanism includes:

[0010] A drive column is fixedly disposed between the two take-up rollers, and the drive column extends through one of the take-up rollers and out of the fixed seat;

[0011] A handwheel is rotatably mounted on the side wall of the fixed base and is fixedly connected to the drive column.

[0012] Furthermore, the positioning mechanism includes:

[0013] The second cavity is provided on one side of the first cavity, and the driving column passes through the second cavity;

[0014] A first friction disc is rotatably disposed on the side wall of the second cavity, and the first friction disc is fixedly connected to the drive column.

[0015] The second friction disk is slidably disposed within the second cavity;

[0016] Two bidirectional screws are rotatably disposed between two mutually distant sidewalls of the second cavity, and the bidirectional screws pass through the two second friction discs by threaded engagement.

[0017] A synchronous rotation mechanism is provided on the fixed base and is used to drive the two bidirectional screws to rotate synchronously.

[0018] Furthermore, the synchronous rotation mechanism includes:

[0019] The first gear is fixedly mounted on the bidirectional screw.

[0020] A first gear ring is rotatably disposed on the side wall of one of the second cavities, and the first gear meshes with the first gear ring;

[0021] A drive mechanism is provided on the fixed base and is used to drive the bidirectional screw to rotate.

[0022] Furthermore, the drive mechanism includes:

[0023] A third cavity is formed within the fixed base, and one of the bidirectional screws passes through the third cavity;

[0024] A first bevel gear is fixedly mounted on the side wall of the third cavity, and the bidirectional screw passes through the first bevel gear and is fixedly connected to the first bevel gear.

[0025] The second bevel gear is rotatably mounted on the side wall of the third cavity, and the second bevel gear meshes with the first bevel gear;

[0026] A drive assembly is mounted on the fixed base and is used to drive the second bevel gear to rotate.

[0028] An internal hex head, wherein the internal hex head is rotatably mounted on the fixed base;

[0029] A drive rod is fixedly disposed between the internal hexagonal head and the second bevel gear.

[0030] The working principle and beneficial effects of this utility model are as follows:

[0031] 1. In this utility model, by setting up a rotating mechanism, after the user passes the upper arm through the gap between the strap and the height gauge, the user can drive the drive column and the take-up roller to rotate by rotating the handwheel, so that the strap is wrapped around the take-up roller and the upper arm and the height gauge are fixed by the wrapping of the strap.

[0032] 2. In this utility model, by setting up a positioning mechanism, the internal hexagon head can be turned by an internal hexagon wrench, thereby driving the bidirectional screw to rotate through the transmission between the second bevel gear and the first bevel gear. At the same time, through the transmission between the first gear and the second gear, the two bidirectional screws can be driven to rotate synchronously. Then, through the threaded engagement between the bidirectional screw and the second friction disc, the second friction disc is driven to press against the first friction disc. Thus, the friction between the first friction disc and the second friction disc can be used to position the drive column and the take-up roller, preventing the height gauge from becoming loose on the boom due to the rotation of the take-up roller.

[0033] 3. In this utility model, the setting of the fixed seat, mounting groove, binding strap, winding roller, rotating mechanism and positioning mechanism facilitates the fixing of winding and binding strap by the friction between the first friction plate and the second friction plate, thereby avoiding the binding strap from loosening and affecting the fixing effect of the altimeter, thus solving the problem of low fixing stability of altimeter in the prior art during use.

Detailed Implementation

[0040] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0041] like Figures 1-4As shown, this embodiment proposes a parachute assist device, including an altimeter 1, a fixed base 2, mounting slots, straps 6, a take-up roller 7, a rotating mechanism, and a positioning mechanism. The fixed base 2 is fixedly mounted on the side wall of the altimeter 1. Two first cavities 3 are formed inside the fixed base 2. A fixing opening 4 is formed on the bottom wall of the inner cavity 3. Two mounting slots are formed on the side wall of the altimeter 1 away from the fixed base 2. Mounting posts 5 are rotatably mounted in the mounting slots. Straps 6 are fixedly mounted on the side wall of the mounting posts 5. The take-up roller 7 is rotatably mounted in the first cavity 3. The end of the straps 6 away from the mounting posts 5 is fixedly mounted on the side wall of the take-up roller 7. The rotating mechanism is set on the take-up roller 7 to drive the take-up roller 7 to rotate. The positioning mechanism is set on the fixed base 2 to position the take-up roller 7.

[0042] Reference Figure 3 The rotating mechanism includes a drive column 8 and a handwheel 9. The drive column 8 is fixedly installed between two take-up rollers 7. The drive column 8 passes through one of the take-up rollers 7 and extends out of the fixed seat 2. The handwheel 9 is rotatably installed on the side wall of the fixed seat 2. The handwheel 9 is fixedly connected to the drive column 8. After the user passes the upper arm through the gap between the strap 6 and the height gauge 1, the drive column 8 and the take-up roller 7 can be rotated by rotating the handwheel 9, so that the strap 6 is wrapped around the take-up roller 7 and the upper arm is fixed to the height gauge 1 by the wrapping of the strap 6.

[0043] Reference Figure 3 and Figure 4 The positioning mechanism includes a second cavity 10, a first friction disc 11, a second friction disc 12, a bidirectional screw 13, and a synchronous rotation mechanism. A second cavity 10 is formed on one side of the first cavity 3. A drive column 8 passes through the second cavity 10. The first friction disc 11 is rotatably mounted on the side wall of the second cavity 10 and is fixedly connected to the drive column 8. The second friction disc 12 is slidably mounted within the second cavity 10. Two bidirectional screws 13 are rotatably mounted between two mutually distant side walls of the second cavity 10. The bidirectional screws 13 pass through the two second friction discs 12 via threaded engagement. The step rotation mechanism is mounted on the fixed base 2 and is used to drive the two bidirectional screws 13 to rotate synchronously. Specifically, the operation of the synchronous rotation mechanism can drive the two bidirectional screws 13 to rotate synchronously. Then, through the threaded engagement between the bidirectional screws 13 and the two second friction discs 12, the second friction discs 12 can be driven to press against the surface of the first friction disc 11. Then, through the friction between the second friction disc 12 and the first friction disc 11, the drive column 8 and the take-up roller 7 are positioned, thereby preventing the take-up roller 7 from rotating and causing the fixing of the strap 6 and the height gauge 1 to loosen.

[0044] Reference Figure 3 and Figure 4The synchronous rotation mechanism includes a first gear 14, a first gear ring 15, and a drive mechanism. The first gear 14 is fixedly mounted on the bidirectional screw 13, and the first gear ring 15 is rotatably mounted on the side wall of one of the second cavities 10. The first gear 14 meshes with the first gear ring 15. The drive mechanism is mounted on the fixed base 2 and is used to drive the bidirectional screw 13 to rotate. The drive mechanism includes a third cavity, a first bevel gear 16, a second bevel gear 17, and a drive assembly. The third cavity is opened in the fixed base 2, and one of the bidirectional screws 13 passes through the third cavity. The first bevel gear 16 is fixedly mounted on the side wall of the third cavity, and the bidirectional screw 13 passes through and is fixedly connected to the first bevel gear 16. The second bevel gear 17 is rotatably mounted on the side wall of the third cavity. The wheel 17 meshes with the first bevel gear 16. The drive assembly is mounted on the fixed base 2 and is used to drive the second bevel gear 17 to rotate. The drive assembly includes an internal hexagon head 18 and a drive rod. The internal hexagon head 18 is rotatably mounted on the fixed base 2, and the drive rod is fixedly mounted between the internal hexagon head 18 and the second bevel gear 17. Specifically, the operator can use an internal hexagon bolt to tighten the internal hexagon head 18, thereby driving the second bevel gear 17 to rotate through the drive rod. At the same time, the meshing of the second bevel gear 17 with the first bevel gear 16 can drive one of the double-acting screws 13 and one of the first gears 14 of the first bevel gear 16 to rotate. Furthermore, the meshing of the first gear 14 with the first gear ring 15 can drive the two double-acting screws 13 to rotate synchronously.

[0045] In this embodiment, during use, after the user passes the upper arm through the gap between the strap 6 and the height gauge 1, the drive column 8 and the take-up roller 7 can be rotated by turning the handwheel 9. This causes the strap 6 to wrap around the take-up roller 7, and the upper arm is fixed to the height gauge 1 through the wrapping of the strap 6. Afterwards, the operator can use the Allen bolt to tighten the Allen head 18, which will drive the second bevel gear 17 to rotate through the drive rod. At the same time, the meshing of the second bevel gear 17 with the first bevel gear 16 can drive one of the double-acting screws 13 of the first bevel gear 16 and... One of the first gears 14 rotates, and the meshing of the first gear 14 with the first gear ring 15 drives the two bidirectional screws 13 to rotate synchronously. The threaded engagement between the bidirectional screws 13 and the two second friction discs 12 causes the second friction discs 12 to press against the surface of the first friction disc 11. The friction between the second friction discs 12 and the first friction discs 11 is used to position the drive column 8 and the take-up roller 7, thereby preventing the take-up roller 7 from rotating and causing the fixing of the strap 6 and the height gauge 1 to loosen, thus completing the installation and fixing of the height gauge 1 and the boom.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
