Description

Technical area

[0001] This utility model relates to a type of archery sleeve structure, particularly to an arrow sleeve structure for detecting the absence of an arrow and preventing a string from slipping. Technology in the background

[0002] Crossbows, also known as crossbows, feature the elastic accumulator design of a bow mounted horizontally on a frame shaped like a rifle stock, and a string suspension mechanism designed to release the string by pulling the trigger when firing. In addition to the traditional bow-arm design, more and more composite crossbows have appeared on the market in recent years, using the principle of composite bow mechanics. Compared to bows, crossbows generally have a heavier weight and a flatter external trajectory and can be equipped with a more precise sight, making them suitable for precision aiming at longer distances, and the aiming style is more similar to that of firearms.

[0003] A conventional crossbow consists of a bowstring, a rifle body, a launcher, arrows, and other related equipment and accessories. These are tied to an arrow pouch around the user's waist and legs to hold a series of arrows. This requires the user to remove the arrows from the pouch, assemble them, and reposition them after each shot, which is quite cumbersome and inconvenient. This eliminates the steps of drawing and setting up arrows, thus shortening the shooting steps to achieve a one-shot kill, maintaining a high level of accuracy and stability. Many archers opt for crossbows equipped with a quiver, allowing multiple arrows in the quiver to be loaded automatically during the shot, eliminating the need to draw and position the arrows individually.

[0004] In this context, the relevant industry has introduced arrow sheaths that can be used for continuous shooting, such as Taiwan Patent No. I774122 "Crossbow Protection Device." The patent stipulates that a number of arrows are loaded onto the top of the arrow rest part of the bow body through a combination of an arrow magazine, and the lowest of the arrows in the number of arrows falls onto a slide track by the pressure of a hook arm. After a shot, the lowest of the arrows in the number of arrows falls back onto the slide track by the pressure of the hook arm and can be shot again.In addition, the hook portion of the hook arm not only falls by its own gravity, but also is pressed against the hook portion of the hook arm by the spring extension, and when the arrow slot is in an arrow-free state, the hook portion is able to extend into the slide rail, and when the bowstring assembly is slid in the direction opposite to the shooting direction, the hook portion of the hook arm is able to be hooked against the bowstring assembly of the bow body, thereby reminding that the arrows are in the arrow compartment in an arrow-free state.

[0005] However, in the case of the cartridge that allows continuous shooting, the hook arm must have a concave hook portion in the hook area in the squint direction, and this concave hook portion is set so that the effect of the concave portion pressing against the arrows is impaired, and when the cartridge is in a state without arrows, the concave hook portion of the hook portion presses against the bowstring, which limits the possibility of the bowstring being drawn further.Therefore, the hook arm must have a certain length and cannot be flexibly adjusted, so as to limit the position of the bowstring to be pulled further, and is prone to breakage and damage of the concave hook portion of the hook arm and cause the top of the arrow sleeve to be uneven, and due to the restriction of the direction of the concave hook portion, the hook arm can only be swung at the front of the arrow sleeve, which causes inconvenience in the design of the structure of the product, and it is necessary to ensure that the improvement is necessary. Content of the utility model

[0006] Considering the above-mentioned disadvantages of the cartridge, which is known to be capable of continuous recording, the inventor developed the idea of ​​the utility model and, after many discussions and experiments and after many corrections and improvements, found the present utility model.

[0007] The present utility model provides an arrow case structure for detecting the absence of an arrow and preventing a string from being pulled, which is used for attachment to a bow body having a platform for holding arrows and a bowstring extending over the platform, and the structure of an arrow case for detecting the absence of an arrow and preventing the pulling of a string, comprising: an arrow magazine having an arrow slot connected to the arrow platform of the bow body, the arrow slot being used for stacking a plurality of arrows on top of each other;an elastic compression unit comprising a pusher and an elastic member, one end of the pusher being rotatably mounted on the arrow housing and the other end of the pusher being provided with a compression portion, the elastic member using elasticity to cause the compression portion of the pusher to press downward against the uppermost arrow body located in the arrow channel in a normal state;and a stringer provided in the arrow rest platform, the stringer having a first end and a second end opposite the first end, the stringer being pivotable on the arrow rest platform between the first end and the second end. The tailpiece is provided with a bearing portion on the upper surface of the tailpiece near the first end, and the second end of the tailpiece is provided with a stop portion, and the tailpiece is pivotable between the stop portion and the bearing portion at the pivot point of the platform. The bearing portion is used to provide downward pressure to the pressure portion of the pressure member to raise the stop portion of the tailpiece to allow the stop portion to stop the draw of the bowstring, thereby signaling that the arrow is no longer in the arrow case.

[0008] The main purpose of this utility model is to realize the structure of an anti-arrow pull archery box without arrows, in which the pressure member is equipped with a pressure part for pressing against the arrows, which ensures a good effect of the pressure against the arrows, and the pressure part is not broken and damaged by the pulling force of the bowstring, so that the durability and service life of the archery box is increased.

[0009] Another purpose of the present utility model is to recognize the structure of the arrow box without arrow and prevent the pulling of the bowstring when the arrow box is in the state without arrow, is to block the pulling of the bowstring through an arrow making seat, so that the position of the flexible pressing unit can be flexibly changed to provide diversified choices for the design of the structure of the product.

[0011] A further description of the better embodiment of the present utility model follows so that those familiar with the technology of the present utility model can implement it as described in this manual.

[0012] As in the Fig. As shown in Figures 1 to 7, the present invention includes an arrow holding platform 1A, a bowstring 1B spanned across the arrow holding platform 1A, and a bow string 1C for installing the present invention on a bow body 1 (in the present embodiment, the bow body is a crossbow). A slide rail 1D is provided on the arrow holding platform 1A, and a receiving slot 1E is provided on the underside of the slide rail 1D. The arrow sleeve structure 2 for detecting the absence of arrows and preventing string pulling includes: an arrow case 10, an elastic compression unit 20, a string holder 30, and a gauge 40.

[0013] The arrow case 10 is in the shape of a long box with a front end 10A and a rear end 10B, and the arrow case 10 is provided with an arrow placement channel 11 running from top to bottom, and the arrow placement channel 11 is connected to the arrow holding platform 1A of the bow body 1. The arrow placement channel 11 is connected to the arrow holding platform 1A of the bow body 1, and the arrow placement channel 11 is used for stacking a plurality of arrows 12 on top of each other, and each of the arrows 12 is provided with a nock 121, and the nock 121 of each of the arrows 12 is aligned in the firing direction 1C.

[0014] The elastic compression unit 20 includes a pressing member 21 and an elastic member 22. The pressing member 21 is in the form of an elongated strip with a pin hole 211 provided at one end for a pivot pin 212 on the arrow housing 10, and a pressing portion 213 provided at the other end of the pressing member 21. The elastic member 22 is provided at the pivot point of the pressing member 21 and the arrow housing 10, and the elastic member 22 utilizes elasticity to press the pressing portion 213 of the pressing member 21 downward and elastically against the uppermost arrow body 12 located in the arrow placement channel 11. In this embodiment, the pressing member 21 is rotatably mounted on the outside of the arrow placement channel 11 of the arrow housing 10, and the elastic member 22 is a torsion spring.

[0015] The tailpiece 30 is arranged in the receiving slot 1E of the slide rail 1D. The tailpiece 30 has a first end 30A and a second end 30B opposite the first end 30A. The tailpiece 30 is rotatably supported between the first end 30A and the second end 30B on the arrow support platform 1A (in this embodiment). The tailpiece 30 is provided with a shaft hole 31 for a shaft 32 through which it eccentrically pivots near the first end 30A, a bearing portion 33 on the top of the tailpiece 30 near the first end 30A, and an inclined stop portion 34 at the second end 30B of the tailpiece 30.The pivot point of the tailpiece 30 and the arrow resting platform 1A is located between the abutment portion 34 and the bearing portion 33, and the tailpiece 30 is pressed against the arrow body 12 located in the arrow placement channel 11 by the weight of the tailpiece 30 and the arrow body 12 located in the arrow placement channel 11 in the normal state, and the abutment portion 34 of the tailpiece 30 abuts the end of the receiving slot 1E, so that the top of the tailpiece 30 is formed to be horizontally hidden in the receiving slot 1E. The bearing portion 33 serves to push the pressing portion 213 of the pressing member 21 downward to lift the stopper portion 34 of the tailpiece 30 so that the stopper portion 34 can block the pulling of the bowstring 1B, thereby detecting that there is no arrow body 12 in the arrow channel 11 of the arrow case 10.

[0016] The gauge 40 is arranged on top of the arrow housing 10, with a pivoting portion 41 and a pin 42 at one end and a snap-in portion 43 at the other end. The pivoting portion 41 is pivotable at the rear end 10B of the arrow housing 10, and the snap-in portion 43 is movably engaged at the front end 10A of the arrow housing 10. In this embodiment, the pin 42 is provided for one end of the pressure element 21 to be inserted. The pivot pin 212 is rotatably mounted in the pin 42 of the gauge 40, with the pin hole 211 being penetrated by the pivot pin 212. The elastic element 22 is inserted onto the pivot pin 212 and resiliently engages the pin 42 between the pressure element 21 and the pin 42.

[0017] In use, as in Fig. As shown in Fig. 8, the elasticity of the elastic member 22 is used to press the pressing portion 213 of the pressing member 21 downward against the arrow body 12 in the arrow slot 11, so that the lower arrow body 12 falls onto the slide rail 1D of the arrow holding platform 1A of the bow body 1. The arrow body 12 on the slide rail 1D is ejected by the taut bowstring 1B, and in this way, the arrows 12 in the arrow slot 11 are ejected one by one, reducing the steps of drawing out and setting up the arrows and enabling the use of continuous squinting.

[0018] After all arrows 12 have been ejected into the arrow slot 11 of the arrow magazine 10, as shown in the Fig. 9 and Fig. As shown in FIG. 10, the bearing portion 33 of the string holder 30 is supplied to the pressing portion 213 of the pressing member 21 to apply downward pressure, so that the stopper portion 34 of the string holder 30 is lifted upward. When the bowstring 1B is pulled in the opposite direction to the firing direction 1C, the stopper portion 34 of the string holder 30 blocks the pulling of the bowstring 1B, thereby detecting and reminding that there are no arrows 12 in the arrow slot 11 of the magazine 10, and preventing damage to the relevant devices and fittings of the bow body 1 due to the firing of the arrow case 10 in a state where it contains no arrows.

[0019] If there are no arrows in the arrow slot 11 of the arrow housing 10, as in Fig.11, the snap portion 43 of the gauge 40 is connected to the front end 10A of the detached arrow case 10, and then the gauge 40 is pivoted upward and backward with the pivot portion 41 as an axis to raise the gauge 40, and together with it, the pressure member 21 is pivoted upward and backward, so that the pressure member 21 is detached from the arrow slot 11. Then, a predetermined number of arrow bodies 12 can be loaded into the arrow slot 11 and stacked one on top of the other with the cam 121 of each arrow body 12 facing the firing direction 1C, and then the tailpiece 30 can be pivoted downward so that the bearing portion 33 of the tailpiece 30 is snapped back onto the front end 10A of the arrow case 10. The pressure section 213 of the pressure element 21 presses downward against the uppermost arrow body 12 in the arrow slot 11 to complete the loading of the arrow so that shooting can continue.

[0020] The following advantages can be obtained from the structure of the above-mentioned specific embodiments: 1. The present utility model detects an arrow sleeve structure for detecting the absence of an arrow and preventing a string, and the pressing member 21 is provided with a pressing portion 213 for pressing, which can ensure a good effect of pressing against the arrow body, and the pressing portion 213 is not broken and damaged due to the tensile force of the bowstring 1B, and the durability and service life of use are improved. 2. The present utility model has an arrow sleeve structure for detecting the absence of an arrow and preventing the bowstring from being drawn. When the arrow slot 11 of the arrow case 10 contains no arrows, the drawing of the bowstring 1B is blocked by a string holder 30, and thus the position of the elastic compression unit 20 can be flexibly changed, providing a wide range of design possibilities for the product structure.
