Description

[Technical field]

[0001] The present invention relates to a toy gun, and more particularly to a toy gun capable of maintaining initial velocity when fired. [Background technology]

[0002] There are many kinds of toy guns, but the most common toy guns use air pressure as a power source to fire bullets. Figures 10 and 11 show a conventional adjustable bolt 80 for a toy gun. The bolt 80 includes a bolt head 81, a bolt base 82, an adjustment member 83, an adjustment base 84 and an elastic member 85. One end of the bolt head 81 is provided with a firing hole 811 communicating with an air intake 812, the bolt base 82 is telescopically inserted into the bolt head 81, the adjustment member 83, the adjustment base 84 and the elastic member 85 are provided in the bolt head 81, the adjustment base 84 is screwed into the bolt base 82, and the adjustment member 83 is located between the firing hole 811 and the air intake 812. The adjustment base 84 can be rotated relative to the bolt base 82 in a follower manner, and the adjustment base 84 and the elastic member 85 press the adjustment member 83 from both sides to position the adjustment member 83. When it is desired to adjust the initial velocity of the percussion, the wrench W is inserted into the percussion hole 811 to engage with the adjustment member 83 and then turned. The adjustment base 84 is driven by the adjustment member 83 to be screwed into or loosened from the bolt base 82, thereby moving and positioning the adjustment member 83 within the bolt head 81. The position of the adjustment member 83 between the percussion hole 811 and the air intake 812 is changed, thereby adjusting the amount of air flowing from the air intake 812 to the percussion hole 811, thereby achieving the effect of adjusting the initial velocity of the percussion. Summary of the Invention [Problem to be solved by the invention]

[0003] However, in this configuration, when a bullet is fired, the recoil of the shot vibrates the adjustment base 84 so that it rotates relative to the bolt base 82, and the adjustment member 83 may deviate from the adjusted position. For this reason, the conventional adjustable bolt 80 is further provided with a positioning ring 86. The positioning ring 86 is provided at the screw-in position of the adjustment base 84 and the bolt base 82, and is intended to prevent the adjustment base 84 from rotating relative to the bolt base 82 due to recoil by friction. However, in order to ensure smooth adjustment, the function of the positioning ring 86 is limited, so that the adjustment member 83 and the adjustment base 84 still vibrate within the bolt head 81, and the adjustment base 84 still rotates relative to the bolt base 82, so that the initial velocity of the shot changes continuously even after adjustment, and the value set during adjustment cannot be maintained.

[0004] The present invention provides a toy gun capable of maintaining the initial velocity of a shot, in order to solve the problem that the initial velocity of a shot of a conventional adjustable bolt of a toy gun changes continuously due to unstable positioning after adjustment and cannot be maintained at the value set during adjustment. [Means for solving the problem]

[0005] The toy gun capable of maintaining an initial velocity of firing of the present invention, which is provided to solve the above-mentioned problems, includes a gun body; a hollow bolt body provided within the gun body; a bolt assembly including: a positioning assembly that is provided within the bolt body and can rotate and move linearly relative to the bolt body and has a plurality of annularly arranged grooves; and a positioning assembly that includes a positioning member and an elastic unit, the elastic unit is provided at a fixed position of the bolt body, and the positioning member is pressed against one of the grooves of the adjustment assembly to limit the rotation of the adjustment assembly relative to the bolt body. Effect of the Invention

[0006] The technical means of the present invention have the following advantages. In conventional adjustable bolts, which have a positioning ring for positioning at the screw-in position between the adjustment base and the bolt base, there is a problem that the initial firing velocity is easily deviated from the set value after adjustment due to the influence of recoil. In contrast, in the present invention, when adjustment is performed, a torque exceeding a certain value is applied to turn the adjustment assembly, which causes the positioning member to elastically deform the elastic unit, thereby allowing it to move between the multiple grooves. After adjustment, the elastic unit presses the positioning member into one of the grooves, which effectively prevents the adjustment assembly from vibrating in a rotational manner relative to the bolt body when subjected to recoil, and prevents the adjustment assembly from being displaced, thereby providing a toy gun that can maintain the initial firing velocity.

[0008] In order to provide a detailed understanding of the technical features and practical effects of the present invention and to be able to realize the present invention based on its contents, the following detailed description will be given with reference to the embodiments as shown in the drawings.

[0009] A toy gun capable of maintaining an initial firing velocity according to an embodiment of the present invention includes a gun body and a bolt assembly. As shown in FIGS. 1, 2 and 5, the bolt assembly includes a bolt body and an adjustment assembly. The bolt body is hollow and includes a bolt head 10 and a bolt base 20. The adjustment assembly includes an adjustment member 30 and an adjustment base 40. The adjustment assembly further includes an elastic member 50 and a positioning assembly 60. The adjustment member 30, the adjustment base 40 and the elastic member 50 are disposed within the bolt body along the axial direction of the bolt body and are located between the bolt head 10 and the bolt base 20. The positioning assembly 60 is disposed on the bolt body and is used to position the adjustment assembly.

[0010] As shown in Figures 2 to 4, the bolt head 10 has a space therein, and is provided with a percussion hole 11, an air intake hole 12, a groove 13, and a positioning hole 14. The percussion hole 11 extends from the tip of the bolt head 10 (left side in Figure 2) inward along the axial direction of the bolt head 10. The groove 13 is located inside the bolt head 10 and is arranged along the axial direction of the bolt head 10. The inside of the groove 13 communicates with the air intake hole 12. The percussion hole 11 extends to the groove 13 and communicates with the air intake hole 12 via the inside of the groove 13. The positioning hole 14 is arranged to penetrate the bolt head 10 in the radial direction and extends inward from the side of the bolt head 10.

[0011] 2 and 3, the bolt base 20 is inserted into the bolt head 10 from the rear end thereof (the right side in FIG. 2) and fixedly coupled to the bolt head 10. Specifically, as shown in FIG. 5 and 6, the bottom of the bolt head 10 is provided with two first coupling holes 16 that are linearly opposed to each other, the bolt base 20 is provided with a second coupling hole 22, and a coupling rod 200 is inserted through the first coupling holes 16 and the second coupling hole 22 to fixedly couple the bolt head 10 and the bolt base 20, and the bolt base 20 is provided with a screw hole 21.

[0012] As shown in FIGS. 2 and 3, the adjustment member 30 of the adjustment assembly can be rotated to move linearly between the air intake hole 12 and the firing hole 11 along the axial direction of the bolt head 10, and the adjustment base 40 of the adjustment assembly is screwed into the bolt base 20 to press the adjustment member 30 from right to left in FIG. 2, and the elastic member 50 is pressed against the adjustment member 30 from left to right in FIG. 2, so that the adjustment member 30 is positioned between the adjustment base 40 and the elastic member 50.

[0013] 5 and 6, the adjustment member 30 includes an adjustment portion 31 and a plurality of first abutment claws 32 located at opposite ends, the adjustment portion 31 is hexagonal and extends into the groove 13 toward the percussion hole 11. The adjustment base 40 includes a screw portion 41 and a plurality of second abutment claws 42 located at opposite ends, the screw portion 41 is screwed into the screw hole 21 of the bolt base 20, the second abutment claw 42 fits together with the first abutment claw 32, and the elastic member 50 is a compression spring that is disposed in the groove 13 and surrounds the adjustment portion 31. One end of the elastic member 50 is pressed against the bottom of the groove 13, and the other end of the elastic member 50 is pressed against the connection point between the adjustment portion 31 and the plurality of first abutment claws 32.

[0014] As shown in Figs. 1 to 3, when adjusting the initial velocity of a bullet when it is shot (i.e., the initial velocity of the percussion), a wrench W is inserted into the bolt head 10 through the percussion hole 11, and the wrench W, which is a hexagonal wrench, is fitted into the adjustment part 31 to rotate the adjustment member 30 in a driven manner, and the first abutment claw 32 is pressed against the second abutment claw 42 to rotate the adjustment base 40 in a driven manner, and the screw part 41 is screwed into or loosened from the screw hole 21 of the bolt base 20, so that the adjustment member 30 moves linearly between the air intake hole 12 and the percussion hole 11 in response to the movement of the adjustment base 40, thereby changing the passage cross-sectional area between the air intake hole 12 and the percussion hole 11, and adjusting the amount of airflow flowing toward the percussion hole 11, thereby achieving the effect of adjusting the initial velocity of the percussion. Since the elastic member 50 is elastically deformed in accordance with the linear movement of the adjustment member 30 and continues to abut against the adjustment member 30, it is possible to maintain the positioning after the adjustment is completed.

[0015] As shown in Figures 5 to 7, the adjusting base 40 further includes a plurality of grooves 43, which are located between the threaded portion 41 and the second abutment claw 42 and are arranged in a ring shape around the axial direction of the bolt head 10. The positioning assembly 60 includes a connecting member 61, a positioning member 62 and an elastic unit 63. As shown in Figures 3 and 5, the positioning assembly 60 is installed along the radial direction of the bolt body. Specifically, the connecting member 61 is connected to the positioning hole 14 of the bolt head 10, the positioning member 62 is disposed between the connecting member 61 and the adjusting base 40, and the elastic unit 63 is a compression spring. One end of the elastic unit 63 is connected to a fixed position of the connecting member 61, and the other end of the elastic unit 63 presses the positioning member 62 against one of the grooves 43 to limit the rotation of the adjusting base 40 relative to the bolt head 10.

[0016] When adjusting the initial velocity of the percussion, the operator applies a torque exceeding a certain value with the wrench W to allow the adjustment member 30 and the adjustment base 40 to rotate relative to the bolt body, so that the positioning member 62 compresses the elastic unit 63, and the positioning member 62 moves out of the original groove 43 and among the grooves 43, and when the positioning member 62 moves to the groove 43, the adjustment of the initial velocity of the percussion is completed. The operator does not apply a torque to rotate the adjustment member 30, and the elastic unit 63 presses the positioning member 62 into the groove 43, thereby repositioning the adjustment assembly and restricting the rotation of the adjustment assembly.

[0017] 1 to 3 and 8, the bolt assembly further includes a bolt sleeve 71, and after adjustment is completed, the bolt assembly is mounted in the gun body 90 of the toy gun via the bolt sleeve 71, a first space 711 and a second space 712 are formed in the bolt sleeve 71, the bolt assembly is mounted in the first space 711, the bolt sleeve 71 is provided with opposing openings 713 for communicating with the second space 712 and the outside of the bolt sleeve 71, and the tension spring 714 closes the gap between the first space 711 and the second space 712 to separate them. The bolt assembly further includes an elastic buffer member 72, and in the embodiment of the present invention, a tension spring is used as the buffer member 72, and a tension spring pin 23 is provided inside the bolt base 20, and opposite ends of the buffer member 72 are respectively provided to the tension spring pin 23 and the tension spring 714 to respond to recoil.

[0018] In use, when a bullet is fired from the firing hole 11 by gas, as shown in Fig. 9, the bolt sleeve 71 moves toward the right side of Fig. 9 relative to the bolt assembly under the effect of recoil, pulling away the buffer member 72 and compressing the return spring 91. At this time, the bolt assembly is reduced in the area surrounded by the bolt sleeve 71, which contributes to the dissipation of the firing gas inside the bolt body, and the recoil also acts on the bolt body and its internal members, and the positioning member 62 is pressed against the groove 43, which prevents the adjustment assembly from vibrating to rotate relative to the bolt body due to the recoil and prevents the adjustment assembly from moving from the adjusted position, so that the adjustment assembly is stably positioned at the adjusted position and the initial velocity of the shot can be maintained at the value set during adjustment even after the bullet is fired.

[0019] In the conventional adjustable bolt 80 of a toy gun, which is provided with a positioning ring 86 for positioning the screwing position of the adjustment base 84 and the bolt base 82, there is a problem that the initial velocity of the shot is easily deviated from the set value after adjustment due to the influence of recoil. In contrast, in the present invention, when adjusting, a torque exceeding a certain value is applied to rotate the adjustment assembly, so that the positioning member 62 elastically deforms the elastic unit 63 and moves between the plurality of grooves 43, and after adjustment, the elastic unit 63 presses the positioning member 62 into one of the grooves 43, thereby restricting the rotation of the adjustment assembly relative to the bolt body, positioning the adjustment assembly, and effectively preventing the adjustment assembly from vibrating to rotate relative to the bolt body when subjected to recoil, thereby preventing the adjustment assembly from being displaced. This provides a toy gun that can maintain the initial velocity of the shot.

[0020] As shown in Fig. 2, in the embodiment of the present invention, the bolt assembly further includes a position limiting member 73, which is fixed on the bolt sleeve 71 by a screwing manner, and a stop step 15 is formed on the outer periphery of the bolt head 10. As shown in Fig. 9, the limit of the stroke of the bolt sleeve 71 relative to the bolt head 10 due to recoil is set until the position limiting member 73 is pressed against the stop step 15, and the bolt sleeve 71 pulls the bolt head 10 and moves slightly further backward (to the right in Fig. 9). After the effect of recoil is over, the return spring 91 and the buffer member 72 return the bolt sleeve 71, the bolt head 10, and the bolt base 20 to their original positions, completing one firing operation.

[0021] In one embodiment of the present invention, the positioning assembly 60 includes the connecting member 61, and the elastic unit 63, which employs a compression spring, is fixedly installed in the positioning hole 14 of the bolt head 10 by pressing against the connecting member 61, but in other embodiments, the connecting member 61 and the positioning hole 14 may be omitted, and the elastic unit 63 may be directly installed in a hole groove recessed in the inner surface of the bolt head 10, or another elastic member may be used as the elastic unit 63 and directly connected to the bolt body. In other words, as long as the elastic unit 63 is installed at a fixed position of the bolt body and the positioning member 62 is pressed into the groove 43 to achieve the positioning effect of the present invention, the installation manner of the positioning member 62 and the elastic unit 63 may be any.

[0022] In the embodiment of the present invention, the adjustment assembly includes an adjustment member 30 and an adjustment base 40, which is screwed into the bolt base 20 and cooperates with the elastic member 50 to achieve the effect of adjusting and positioning by linear movement. However, in other embodiments, the adjustment assembly and the elastic member 50 may adopt the adjustment structure of a conventional toy gun bolt, that is, the adjustment assembly is provided with a plurality of the grooves 43, and the positioning member 62 is pressed into the groove 43 by the elastic unit 63 to position the adjustment assembly and the bolt body, and when a torque exceeding a certain value is applied, the elastic unit 63 is elastically deformed to move the positioning member 62 between the plurality of grooves 43, so that the type of the adjustment assembly is not limited to the embodiment of the present invention.

[0023] In the embodiment of the present invention, a positioning ball is used as the positioning member 62, and the bottom surface of the groove 43 is arc-shaped, but in other embodiments, the positioning member 62 may be an elongated member whose arc-shaped end contacts the groove 43, and the bottom surface of the groove 43 may be a flat surface connecting both slopes, so that when the adjusting base 40 rotates, the positioning member 62 can move along either slope to the other groove 43. Note that the types of the positioning member 62 and the groove 43 are not limited to those in the embodiment of the present invention.

[0024] 3 to 5, in the embodiment of the present invention, the connecting member 61 is screwed into the positioning hole 14, so that not only can the connecting member 61, the positioning member 62, and the elastic unit 63 be easily removed, but also, when the positioning effect of the elastic unit 63 is reduced due to elastic fatigue, the connecting member 61 can be further screwed into the bolt head 10 again to stably press the positioning member 62 into the recessed groove 43, thereby providing a reliable positioning effect. Furthermore, as shown in Figs. 4 and 5, the connecting member 61 is further provided with an accommodation groove 611, in which the elastic unit 63 is accommodated, and the accommodation groove 611 can restrict the elastic unit 63 so that it does not shift during the process of elastic deformation.

[0025] In addition, when adjusting the initial velocity by turning the adjusting member 30 with a wrench W, the sound and snap-fit ​​feeling generated each time the positioning member 62 is pressed into the groove 43 by the elastic unit 63 can be used to alert the operator to the currently adjusted distance. As shown in FIG. 5, in this embodiment of the present invention, the grooves 43 of the adjusting base 40 are arranged equiangularly distributed, and each time the positioning member 62 moves from one groove 43 to the next, it means that the adjusting base 40, together with the adjusting member 30, has moved a fixed distance along the axial direction of the bolt head 10. This contributes to a stable adjustment of the initial velocity of the shot and makes it easier to clearly quantify the adjustment of the initial velocity of the shot, making the use of the toy gun more convenient.
