Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic throwers, in particular to a handheld electromagnetic thrower. Background Art

[0002] As an advanced tool, handheld electromagnetic throwers play an important role in many fields, such as fire rescue, police operations and special engineering operations. However, the strong recoil generated by them during operation has always been a problem that needs to be solved urgently.

[0003] In the working principle of the electromagnetic catapult, the instantaneous release of electromagnetic energy will generate huge thrust, launching the projectile at high speed. While this powerful thrust brings efficient casting effect, it will also produce considerable recoil. Traditional handheld electromagnetic catapults often do not fully consider the impact of recoil in their design, or the buffering measures used are not effective.

[0004] In fire rescue scenarios, rescuers need to quickly and accurately throw rescue ropes, life-saving equipment, etc. to the designated location. However, if the recoil is too large and not effectively buffered, it will not only affect the accuracy of the throw, but may also cause the rescuer to lose balance or even get injured, delaying the rescue. In police operations, it is crucial to accurately throw specific items to the target area. Strong recoil may interfere with the operator's aiming and judgment, affecting the execution of the task.

[0005] In addition, for workers who use handheld electromagnetic throwers for a long time, frequently enduring large recoil forces may lead to cumulative injuries, such as hand joint pain, muscle strain, etc., which will not only affect their work efficiency, but may also have long-term negative effects on their physical health. Therefore, in order to improve the safety, accuracy and comfort of handheld electromagnetic throwers, it is particularly important to design an effective buffering and shock-absorbing structure.

[0006] Therefore, we propose a handheld electromagnetic thrower. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant literature, and several embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0030] Example 1

[0031] like Figure 1-5 As shown, the utility model provides a technical solution: a handheld electromagnetic thrower, including an electromagnetic thrower structure 1, a supporting connection structure 2 is provided at the bottom of the electromagnetic thrower structure 1, and the electromagnetic thrower structure 1 can slide on the supporting connection structure 2.

[0032] This device can protect the operator, significantly reduce the recoil force transmitted to the hands and chest, reduce the risk of injury, ensure the safety of the operator, and prevent the operator from fatigue or injury due to accumulated recoil impact during long-term or frequent operations. For example, personnel who have been engaged in firefighting and rescue work for a long time may suffer from wrist tenosynovitis, shoulder muscle strain and other problems after using traditional electromagnetic throwers many times. The new buffering and shock-absorbing structure 4 can significantly reduce this direct impact, disperse and absorb the recoil force, which means that even in frequent and high-intensity usage scenarios, operators can avoid cumulative injuries.

[0033] It can also improve operational stability, reduce the shaking caused by recoil, and make throwing more accurate and stable. For example, when performing precise rescue or specific tasks, the target object can be thrown to the designated location more accurately. Take rope throwing in fire rescue as an example. If the throwing direction deviates due to recoil, the rope may not reach the location of the trapped person, thereby delaying the rescue time. The new buffering and shock-absorbing structure 4 can reduce this shaking and displacement, allowing the operator to better maintain a stable posture and hand control during launch, thereby achieving more accurate throwing.

[0034] Finally, the durability of the equipment can be enhanced. The buffering and shock-absorbing structure 4 can reduce the impact of the recoil on the electromagnetic ejector itself and extend the service life of the equipment, especially for internal precision components, and reduce damage and failures caused by strong impacts. The buffering and shock-absorbing structure 4 absorbs and disperses the recoil, which can significantly reduce the damage to the equipment caused by such impacts. This means that the maintenance frequency and cost of the equipment will be reduced and the service life can be extended. Taking the electromagnetic ejector used by the police department as an example, if there is no buffering and shock-absorbing structure 4, after a period of high-intensity use, it may be necessary to frequently replace parts or overhaul them, which not only increases costs, but may also affect the efficiency of task execution. However, with an effective buffering and shock-absorbing structure 4, the equipment can maintain a good working condition for a longer period of time, reducing task interruptions caused by equipment failures.

[0036] like Figure 1-5 As shown, the utility model provides a technical solution: handheld shock absorbing devices 3 are provided on both side walls of the electromagnetic thrower structure 1, the electromagnetic thrower structure 1 can slide on the two handheld shock absorbing devices 3, and a buffer shock absorbing structure 4 is fixedly connected to the back wall of the electromagnetic thrower structure 1, and the buffer shock absorbing structure 4 can buffer and shock the handheld shock absorbing device 3 when it slides backward. The electromagnetic thrower structure 1 includes an electromagnetic thrower body 101, a handle 102 is provided on the front of the electromagnetic thrower body 101, and a launch tube 103 is provided on the top of the electromagnetic thrower body 101, which can be lifted by the handle 102 when taking it, and the launch tube 103 is used for throwing.

[0037] The supporting connection structure 2 includes a supporting seat 201, and two first slide rails 202 are provided on the top of the supporting seat 201. The inside of the two first slide rails 202 is provided with a first connecting slider 203. The two first connecting sliders 203 can slide on the first slide rails 202. The two first slide rails 202 and the electromagnetic ejector body 101 are fixedly connected, thereby driving the electromagnetic ejector body 101 to slide backward.

[0038] The handheld shock absorbing device 3 includes a fixed plate 301, and a plurality of second slide rails 302 are provided on the inner side wall of the fixed plate 301. Second connecting sliders 303 are provided inside the plurality of second slide rails 302. Launch grips 304 are fixedly connected to the outer sides of the plurality of fixed plates 301. The launching grips 304 are used for holding the device when throwing. The plurality of second connecting sliders 303 can slide on the plurality of second slide rails 302. The plurality of second connecting sliders 303 are fixedly connected to the electromagnetic thrower body 101, thereby driving the electromagnetic thrower body 101 to slide backward.

[0039] The buffering and shock absorbing structure 4 comprises a fixing seat 401 , a plurality of dampers 402 are arranged on the front of the fixing seat 401 , and buffer springs 403 are arranged on the outer sides of the plurality of dampers 402 .

[0040] The back side of the buffer spring 403 is fixedly connected to the fixing seat 401, the front side of the buffer spring 403 is fixedly connected to the electromagnetic ejector body 101, the front end of the damper 402 is fixedly connected to the electromagnetic ejector body 101, and the damper 402 and the buffer spring 403 are used in conjunction with each other.

[0041] The damper 402 includes an outer shell 4021, an outer oil chamber 4022 is provided inside the outer oil chamber 4022, an inner oil chamber 4023 is also provided inside the outer oil chamber 4022, a connecting hole 4024 is provided at the bottom of the inner oil chamber 4023, a connecting rod 4025 is provided at the top of the outer shell 4021, a piston body 4026 is provided at the bottom of the connecting rod 4025 and inside the inner oil chamber 4023, and a plurality of damping holes 4027 are provided on the piston body 4026.

[0042] The working process of the utility model is as follows: when using the handheld electromagnetic thrower, first, when the operator is ready to use the handheld electromagnetic thrower to perform a throwing operation, the operator first holds the launching grip 304 to keep the electromagnetic thrower body 101 stable.

[0043] When performing the throwing operation, the electromagnetic device inside the electromagnetic throwing device body 101 is activated to generate a strong thrust to throw the throwing object out of the launching tube 103.

[0044] At this time, due to the huge recoil force generated, the electromagnetic ejector body 101 will move backwards rapidly, and the first connecting slider 203 fixedly connected to the electromagnetic ejector body 101 at the bottom will slide backwards in the first slide rail 202, and at the same time, the second connecting slider 303 fixedly connected to the electromagnetic ejector body 101 on both sides will also slide backwards in the second slide rail 302.

[0045] As the electromagnetic thrower body 101 moves backward, its front side contacts and squeezes the buffer spring 403, and the buffer spring 403 begins to compress, the internal piston moves, and the oil flows through the holes on the piston to produce a damping effect, thereby absorbing the energy of the recoil force.

[0046] When the buffer spring 403 is compressed, the damper 402 fixedly connected to the electromagnetic ejector body 101 at the front end also starts to play a role. The damper 402 generates resistance to the backward movement of the electromagnetic ejector body 101 through its internal damping mechanism, further reducing the impact caused by the recoil.

[0047] Under the coordinated action of the buffer spring 403 and the damper 402, the recoil force is effectively buffered and dissipated, and the retreat speed of the electromagnetic thrower body 101 gradually decreases and eventually stops.

[0048] When the recoil force disappears, the buffer spring 403 starts to rebound. Due to the limitation of the damper 402, the rebound speed of the buffer spring 403 is controlled, thereby avoiding secondary impact on the equipment and the operator caused by excessive rebound.

[0049] Through the action of the buffering and shock-absorbing structure 4, the recoil force is fully absorbed and controlled, and the impact on the operator's hands and chest during operation is significantly reduced, thereby improving the stability and safety of the operation, while also protecting the precision components inside the equipment and extending the service life of the equipment.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
