Description

Technical Field

[0001] The utility model relates to the technical field of detection devices for throwing life jackets, in particular to a throwing detection device for throwing life jackets. Background Art

[0002] A life jacket is a garment that can prevent drowning and provide emergency lifesaving services. During a rescue, in order for a throwable life jacket to achieve the necessary rescue effect, the rescuer needs to throw the life jacket close to the person being rescued so that the person can use the equipment to ensure their own safety in a short period of time. In addition to wind speed and the weight of the life jacket itself, the design of the life jacket product also has a significant impact on the throwing effect. Therefore, lightweight throwable life jackets (density less than 0.06g / cm3) need to be subjected to a throwing test. During the throwing test, the test content involves the following normative reference documents: ISO 12402-2:2020 Personal flotation devices—Part 2: Lifejackets, performance level 275—Safety requirements for ocean vessels.

[0003] Currently, throw detection is primarily performed through manual throwing and using throw-type life jacket throw detection devices to simulate manual throwing. However, due to the poor stability of manual throwing and large discrepancies in data, throw-type life jacket throw detection devices are increasingly being used for throw detection. However, some existing throw-type life jacket throw detection devices can only test the life jacket from a fixed angle and height during testing, failing to simulate the different heights of throws in real-world rescue environments, nor the effects of different angles on the throw distance of the life jacket. Utility Model Content

[0004] The purpose of the present utility model is to provide a throwing detection device for a throwing life jacket, so as to solve at least one technical problem existing in the above-mentioned background technology.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-4 , an embodiment provided by the utility model:

[0031] Throwing type life jacket throwing detection device, which includes:

[0032] The bottom plate 1 has a limiting groove 2 formed on the bottom plate 1, and an adjusting threaded rod 3 is rotatably installed in the limiting groove 2 through a bearing seat. One end of the adjusting threaded rod 3 passes through the middle of the support plate 4, and the support plate 4 is arranged in the limiting groove 2. The adjusting threaded rod 3 is symmetrically distributed about the support plate 4, and the adjusting threaded rod 3 is threadedly connected to the support plate 4, and the support plate 4 is slidingly connected to the limiting groove 2. The above structural design enables the adjusting threaded rod 3 to stably drive the support plate 4 to slide horizontally and linearly along the limiting groove 2 by utilizing the threaded connection relationship when rotating, and a support rod 5 is rotatably installed on the top surface of the support plate 4;

[0033] When the support plate 4 is displaced, the support rod 5 is rotated stably by the support rod 5, and the support rod 5 drives the movable plate 6 to rotate stably to adjust the tilt angle, and can stably support and position the movable plate 6.

[0034] The base plate 10 has a track rod 11 fixedly mounted on the bottom of the other side of the base plate 10. The track rod 11 passes through the stabilizing hole 12. The stabilizing hole 12 is provided at the bottom of the ejection plate 13. An energy storage spring 14 is fixed to one side of the bottom of the ejection plate 13. The end of the energy storage spring 14 is fixed to the bottom of the base plate 10.

[0035] In one embodiment, the track rod 11 is slidably connected to the stabilizing hole 12, the track rod 11 is symmetrically distributed about the center of the ejection plate 13, and the front view shape of the track rod 11 is a "T" shape. The above structural design ensures that the ejection plate 13 can only move linearly along the track rod 11 and will not slip.

[0036] In one of the preferred embodiments, the ejection plate 13 has a "T" shape when viewed from the front, and the width of the ejection plate 13 is greater than half the width of the base plate 10. The above structural design enables the ejection plate 13 to not only be stably connected to the track rod 11, but also to stably place the life jacket and drive the life jacket to be ejected.

[0037] In one embodiment, a lower positioning hole 15 is provided at the bottom end of the ejection plate 13, and a positioning pin 16 is installed through the lower positioning hole 15. The top of the positioning pin 16 is in contact with the inner wall of the upper positioning hole 17. The upper positioning hole 17 is provided at the bottom end of the track rod 11 near the base plate 10. The above structural design enables the positioning pin 16 to quickly fix the ejection plate 13 and the track rod 11, and at the same time can quickly detach to release the ejection plate 13.

[0038] In one of the preferred embodiments, the positioning pin 16 is tightly fitted with the inner walls of the lower positioning hole 15 and the upper positioning hole 17, and the positioning pin 16 is vertically distributed with the track rod 11. The above structural design ensures that when the positioning pin 16 is connected with the lower positioning hole 15 and the upper positioning hole 17, the ejection plate 13 cannot be displaced and can continue to squeeze the energy storage spring 14 to store elastic potential energy.

[0039] The working principle of this utility model is: the initial state of the device is as follows: Figure 2 As shown, when performing the throwing test, according to the throwing test requirements, first rotate in the same direction at the same time Figure 4 The adjusting threaded rod 3 is symmetrically distributed in the middle, and the adjusting threaded rod 3 uses the threaded connection relationship to drive Figure 2 The support plate 4 in the middle slides horizontally to the right along the limit slot 2 with the support rod 5. The support rod 5 rotates during the right movement and pulls the movable plate 6 to rotate clockwise around the rotating shaft installed at its bottom end until the inclination angle of the movable plate 6, the base plate 10 and the ejection plate 13 is appropriate. The rotation of the adjusting threaded rod 3 is stopped. The adjusting threaded rod 3 uses the thread self-locking to fix the position of the support plate 4. The support plate 4 and the support rod 5 cooperate to stably support the movable plate 6 at a fixed angle.

[0040] Then, the base plate 10 is moved with the locking bolt 8 to slide linearly along the track window 7 until the working height of the base plate 10 and the ejection plate 13 is appropriate. The locking nut 9 is rotated to squeeze the side of the movable plate 6 to fix the working height of the base plate 10 and the ejection plate 13. The life jacket to be tested can be placed on the horizontal part of the ejection plate 13 and quickly pulled down. Figure 3 The pull ropes installed at the bottom ends of the two positioning pins 16 in the middle quickly and completely disengage the positioning pins 16 from the lower positioning holes 15 and the upper positioning holes 17. Under the elastic force of the compressed energy storage spring 14, the ejection plate 13 slides steadily along the track rod 11 away from the base plate 10, driving the life jacket placed thereon to accelerate away from the base plate 10 until the bottom end of the ejection plate 13 contacts the larger diameter disk-shaped structure at the end of the track rod 11 that acts as a barrier. The ejection plate 13 stops and the life jacket is thrown out, completing a throwing test.

[0041] Then push the ejection plate 13 to slide along the track rod 11 and reset it close to the base plate 10, squeeze the energy storage spring 14, and insert the positioning pin 16 into the reset and aligned lower positioning hole 15 and upper positioning hole 17. According to the above operations, change the inclination angle of the movable plate 6 and the working height of the base plate 10, and the throwing distance of the life jacket at different heights and throwing angles can be tested.

[0042] The above is only an embodiment of the present invention, and common knowledge such as the specific structure and characteristics of the scheme are not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
