[0002] The current aerial net gun catchers are classified by power, mainly into gunpowder power and pneumatic power. The existing pneumatic-powered aerial net gun catchers are all to fix the handheld net gun catcher to the drone, install a servo on the drone, and use the servo instead of human hands to trigger the switch of the handheld net gun catcher. However, the existing technology uses servos to trigger, and there are still the following defects: first, all transmission structures are exposed to the outside, without sealing and reliable protection, and are easy to damage; second, the motor structure must rely on the module of the handheld net gun catcher, and rely on the manual button on the handheld net gun catcher to trigger. Although the modular structure is very convenient to repair and replace, and the cost is low, it increases the weight of the whole machine, resulting in limited flight speed and greatly reduced flight time. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model provides a pneumatic power capture net electric trigger, which solves the technical problems that the transmission structure triggered by the servo is easily damaged and the use effect is poor due to the increase in weight.

[0005] The rotating and telescopic assembly includes a key middle shell that is snap-connected to the driving assembly. The key middle shell is sleeved in the base. A latch protrusion is sleeved in the key middle shell. Two symmetrically arranged movable pins are fixed on the outer wall of the latch protrusion. One end of the movable pin is slidably arranged in a spiral groove opened on the inner wall of the outer shell.

[0006] Preferably, the driving assembly comprises a servo installed in a servo cover, a driving gear is installed on a driving shaft of the servo, and a key middle shell is snap-connected to the driving gear.

[0007] Preferably, a positioning groove adapted to the outer extension portion of the steering gear is provided on the inner side of the base.

[0008] Preferably, two semicircular grooves for installing sealing rings are provided on the outer wall of the outer shell.

[0009] Preferably, an inner tooth groove engaged with the driving gear is provided on the inner wall of one end of the button middle shell.

[0010] Preferably, two guide grooves for the movable pin to move are provided on the outer wall of the key middle shell.

[0011] Preferably, the end of the latch protrusion located outside the key shell is conical.

[0012] By means of the above technical solution, the utility model provides a pneumatic power capture net electric trigger, which has at least the following beneficial effects:

[0013] 1. The pneumatic power capture net electric trigger can protect various transmission structures by arranging a steering gear cover, a base, an outer shell and a middle shell lock cover, which can effectively prevent foreign objects from getting stuck in the transmission structure and improve the success rate of the capture net launch.

[0014] 2.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] There are three main structures of the structure triggered by the servo 21 on the market: the first is the simplest one, in which a straight-line single-axis swing arm is installed on the rotating shaft of the servo 21, and the single-axis swing arm is rotated to hit the switch of the handheld net gun catcher to simulate the finger pressing, thereby launching the capture net. The second is based on the first one, using a U-shaped double-axis swing arm, and the U-shaped double-axis swing arm is used to hit the switch of the handheld net gun catcher to simulate the finger pressing, thereby launching the capture net. The third structure has a significant improvement over the first two. The output shaft of the servo 21 is connected by a pull rod to convert the circular motion of the servo 21 into a linear reciprocating motion. This method will be more stable and reliable when pressed perpendicular to the contact surface of the switch of the handheld net gun catcher.

[0026] Based on the technical defects of the existing technology that the transmission structure is easily damaged and the use effect is poor due to the increase in weight, please refer to Figure 1-Figure 6 The utility model provides a pneumatic power capture net electric trigger, which can realize the protection of each transmission structure, effectively prevent foreign objects from getting stuck in the transmission structure, improve the success rate of capturing net launching, and the entire transmission structure is compact and labor-saving, easier to trigger, and reduces the overall weight, which can improve the flight speed and use time. The trigger includes a steering gear cover 1, a driving component 2 is installed in the steering gear cover 1, and a rotating telescopic component 3 for triggering a trigger in a net gun capturer is engaged and connected on the driving component 2. The rotating telescopic component 3 is sleeved in a base 4, which is installed on one side of the steering gear cover 1, and an outer shell 5 is integrally formed on the side of the base 4 away from the steering gear cover 1, and a middle shell lock cover 6 is installed on the side of the outer shell 5 away from the base 4; the whole is installed on the net gun capturer, and then the driving component 2 is used to work and drive the rotating telescopic component 3 to move, and the latch protrusion 32 in the rotating telescopic component 3 will extend into the trigger in the net gun capturer after extending, and then the spring needle in the trigger is triggered to pierce the gas cylinder and release the gas, and the capture net can be launched after air pressure is generated.

[0027] To trigger the trigger, please refer to Figure 2 The rotating and telescopic component 3 includes a key middle shell 31 that is engaged with the driving component 2. The key middle shell 31 is sleeved in the base 4. A latch protrusion 32 is sleeved in the key middle shell 31. Two symmetrically arranged movable pins 33 are fixed on the outer wall of the latch protrusion 32. One end of the movable pin 33 is slidably arranged in a spiral groove 52 opened on the inner wall of the outer shell 5; the driving component 2 drives the key middle shell 31 to rotate. Since the movable pin 33 is restricted in the guide groove 312, when the key middle shell 31 rotates, the movable pin 33 is forced to move in the spiral groove 52, thereby driving the latch protrusion 32 to rotate and extend outward at the same time. When the latch protrusion 32 is completely extended out of the key middle shell 31, the front end of the latch protrusion 32 will enter the trigger and trigger the trigger to work.

[0028] To drive the trigger, please refer to Figure 2 The driving assembly 2 includes a steering gear 21 installed in the steering gear cover 1, a driving gear 22 is installed on the driving shaft of the steering gear 21, and a key middle shell 31 is engaged with the driving gear 22; the steering gear 21 works and drives the driving gear 22 to rotate, and the driving gear 22 and the key middle shell 31 engage with each other, so that the rotating and telescopic assembly 3 can be operated.

[0029] In order to achieve stable installation of the servo 21, a positioning groove 41 adapted to the outer extension of the servo 21 is provided on the inner side of the base 4; the extension of the servo 21 is just in the positioning groove 41. When the base 4 and the servo cover 1 are installed, the servo 21 can be fixed, ensuring the stability of the servo 21 during use.

[0030] To improve the sealing performance, two semicircular grooves 51 for installing sealing rings are provided on the outer wall of the outer shell 5; the sealing rings can be sleeved on the semicircular grooves 51, and after the entire trigger is mounted on the net gun catcher, the sealing performance of the connection can be improved.

[0031] To ensure the stability of transmission between the driving gear 22 and the key middle shell 31, an inner tooth groove 311 engaged with the driving gear 22 is provided on the inner wall of one end of the key middle shell 31. The driving gear 22 can just engage with the inner gear ring, so that when the driving gear 22 rotates, it can smoothly drive the key middle shell 31 to rotate.

[0032] In order to realize the rotation and telescopic movement of the latch protrusion 32, two guide grooves 312 for the movable pin 33 to move are provided on the outer wall of the key middle shell 31; the guide grooves 312 are used to limit the movable pin 33, thereby ensuring that the movable pin 33 can move along the spiral groove 52.

[0033] To ensure that the latch protrusion 32 can successfully trigger the trigger, the end of the latch protrusion 32 on the outside of the key shell 31 is tapered; the tapered design allows the latch protrusion 32 to better enter the firing hole of the trigger and achieve the firing effect.

[0034] Through the above embodiments, it can be known that: the whole is installed on the net gun catcher, and then under the action of the driving component 2, the steering gear 21 is used to work and drive the driving gear 22 to rotate. Under the engagement of the driving gear 22 and the key middle shell 31, the key middle shell 31 is rotated. Since the movable pin 33 is restricted in the guide groove 312, when the key middle shell 31 rotates, the movable pin 33 is forced to move in the spiral groove 52, thereby driving the latch protrusion 32 to rotate and extend outward. When the latch protrusion 32 is completely extended out of the key middle shell 31, the front end of the latch protrusion 32 will enter the trigger and trigger the spring needle in the trigger to pierce the gas cylinder and release the gas, and then the capture net can be launched after the air pressure is generated.

[0035] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0036] 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.
