Description

The invention relates to an improved crossbow shooter, in particular to an improved crossbow shooter which can shoot at night and can be loaded with multiple arrow bodies at one time.

Most of the traditional conventional crossbows have powerful shooting, but they generally only focus on the power of shooting, and have the following disadvantages:

1. Loading is cumbersome: the conventional crossbow uses one arrow body to be shot and then loaded into the next arrow body, which not only results in low efficiency during use and operation, but also makes it impossible to shoot continuously, which greatly reduces the fun of the crossbow. .

2. The operation is laborious. The conventional method of drawing the full bowstring of the crossbow is to pull the string to the buckle groove by the pull rod. However, this kind of pulling method is completely artificially applied to the machine for direct traction, so it must be pulled. With very high force, otherwise it cannot be pulled into the buckle groove.

3. Expensive: Since the conventional crossbows can only be used during the day, it is like "a hero is useless" in the dark. Although there are infrared crossbows that can be aimed at night, the cost of infrared crossbows is relatively high, and It is not acceptable to ordinary people.

The object of the present invention is to provide an improved crossbow shooter that can be used for shooting at night as well as during the day. The crossbow is provided with a loading rack for loading multiple arrow bodies at one time and a driven pulley for pulling and winding the bow more labor-saving. , so that the present invention can stretch the string again immediately after the stringed arrow body is shot out, and fix the arrow body to be stringed, thereby achieving continuity, entertainment, and practical efficiency during use.

The purpose of the present invention is achieved in the following manner:

An improved crossbow shooter, including a bow body and a loading rack, is characterized in that: a loading rack loaded with multiple arrow bodies is obliquely fixed above the bow body, and a vertical guide frame is in the middle of the loading rack. A hook is provided at the upper end of the vertical guide frame, and a steering wheel is pivotally arranged at the lower end of the vertical guide frame. One end of the pressing spring is hooked on the hook, and the other end bypasses the steering wheel and presses against the arrow body. Above; under the arrow body loading slot at the front end of the bow main body, there is a projection lamp tube for aiming. The vertical knob and horizontal knob that move the frame and the projection lamp tube up and down; guide rods are installed in the guide grooves on both sides of the main body of the bow, and a driven pulley is fixed at the front end of the guide rod, and a fixed pulley is fixed in front of the driven pulley. There is a hook body, a buckle block is fixed at the rear of the driven pulley, and a return spring is arranged in front of the hook body. One end of the return spring is hooked on the front end of the main body of the bow, and the other end is hooked on the hook body. On; another rope is set to go around the driven pulley, and the end of the rope is fixed on the pull handle located at the rear end of the main body of the bow.

The advantages of the present invention are:

1. Multiple arrow bodies can be loaded on the loading rack, and the arrow bodies can be continuously pressed into the loading slot one by one through the pressing spring, which is convenient to use.

2. The string is pulled by the handle, the rope, and the driven pulley, so the operation is relatively labor-saving.

3. A projection lamp and a light source are installed on the main body of the bow, which can be used for aiming and shooting at night.

Knob 322, whereby the two knobs 321, 322 are fine-tuned up, down, left, and right, and the positioning rod 31 is used as a fulcrum, so that the light source projected by the lamp tube 3 can overlap with the shooting point after the arrow body 23 is shot, so as to facilitate The crossbow shooter can shoot the arrow body 23 onto the light source point by projecting the light source projection point of the projection lamp tube 3 at night; and the present invention can also arrange the projection lamp tube 3 on the main body at the front end of the bow body 1 1, and the battery 331 is placed in the front handle 6 (see Figure 4), as described above, the projection lamp tube 3 is displaced along the main body 1 through the fine adjustment by tightening or loosening the knob, The light source projected by it can also be adjusted to the shooting point of the arrow body 23, so as to achieve the best utilization of the specific space. Because the projection lamp tube 3 part of the present invention only needs to be provided with a light bulb, a convex lens sheet and a battery inside it, so as far as the projection lamp tube 3 is concerned as a whole, the volume occupied by it is really enough to fully accommodate the device properly. Not only can it be arranged inside or below the front end of the bow main body 1 as mentioned above, but it can also be matched with different crossbow shooters at any position, so that different crossbows can also achieve their projection effects.

Referring to Fig. 5 and 6 again, because the pulling of the string 16 of the present invention is done by the driven pulley 151 as a transformation of the stress on the moment, when the foot hook steps on the pedal handle 5 and gives the pull When the handle 4 is pulled backward, because the through hole 17 at the tail of the bow main body 1 is attached to the rope 18, the rope 18 slides on the driven pulley 151, and the guide rod 15 is pushed backward in the sliding groove 154, and The buckle block 153 is also moved backward, and the string 16 is pulled into the striking groove 161. At this time, the pressure spring 22 on the loading frame 2 temporarily places the head of the arrow body 23 at the bottom. into the L-shaped abutting piece 241 at the tail end of the movable frame 24, and its tail is automatically pressed into the loading groove 11, so that after the trigger 10 is struck, the built-in block (not shown) under the strike groove 161 will be Ejecting out) can make the string 16 break away from the percussion groove 161, and push the arrow body 23 out.

In addition, please refer to Fig. 6 to Fig. 8 for further action description. When the pull handle 4 is pulled backward, the driven pulley 151 attached to the bow body 1 is also displaced backward due to the pull of the rope 18 , and Make a follower rod 25 connected to the follower pulley 151 on the side of bow main body 1 and the screw rod of movable frame 24 move backward, and a nut 251 at the tail end of follower rod 25 is fixed to follower pulley 151 On the protruding screw rod, at an appropriate position in the middle of the shaft, a nut 252 is used to screw it to the screw rod next to the movable frame 24, and because a gasket 253 is placed beside the nut 252, the driven rod 25 can be used as a fulcrum by the nut 252, and slide back and forth on it; in addition, after the driven rod 25 is pulled and driven for a distance, the nut 252 will be pulled accordingly, so that the whole movable frame 24 moves backward. Displacement, at this moment, a bar 242 on the movable frame 24 is replaced to the position of the original arrow body 23 immediately, and prevents the arrow body 23 at the bottom of the loading frame 2 from continuing to be loaded into the filling groove 11, and is placed in the loading frame 2 again. The filling hole 11 directly below is provided with a slot similar to the shape of the arrow body 23 in front of it, so when the arrow body 23 falls into the filling groove 11, the arrowhead portion of the arrow body 23 is supported by the supporting piece 241. Instead of falling directly into the filling groove 11 of the bow main body 1, after the movable frame 24 moves a certain distance, when the arrow part moves to a wider range in the middle of the filling groove 11, the arrow body 23 will slightly fall into it. Fill the slot 11, and the tapered tail 261 at its tail end falls into the filling slot 11 completely in an oblique shape; while the pull handle 4 is pulled backward, because the string 16 is blocked by the pull stopper 153 In addition, and because the buckle stopper 153 is in the shape of a downward arc, so when the string 16 is pulled to the knocking groove 161, it slides down from the buckle stopper 153 into the knocking groove. 161, to complete the winding preparation (see Figure 7); and the original arrow body 23 is moved to the upper edge of the percussion groove 161 by the belt, and is fixed on the bow body 1 by the two shrapnel 111, 112 to fix the arrow body 23, and make the arrow body 23 be positioned at two points near its tail through shrapnel 111, 112, which can make it more stable when shooting (seeing Fig. 6), and after the above-mentioned actions are completed, Make the overall bow main body 1 enter the program that the arrow is on the string and wait for launch.
