Description

Technical Field

[0001] This utility model belongs to the field of archery technology, and in particular relates to a portable training bow and arrow. Background Technology

[0002] A bow and arrow is a combined long-range cold weapon that uses the tension of a bowstring or arm to launch a pointed arrow. For ease of carrying, training equipment is usually designed as a modular structure, requiring assembly before use. However, after assembly, the bowstring needs to be installed at one end, and the installation is difficult because the bowstring needs to be taut on the bow. This paper proposes a structure that allows the bowstring to be installed during bow assembly. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a portable training bow and arrow, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a portable training bow and arrow, comprising an arc rod, two arc rods symmetrically rotatably connected to both sides of a handle, and a ring sleeve slidably provided at the end of the arc rod away from the handle, with a bowstring provided between the two ring sleeves; square tubes slidably connected to both ends of the handle, and the square tubes covering the arc rods; bolts threadedly connected to the square tubes; and grooves provided on the arc rods corresponding to the bolts, with the bolts fitting against the inner wall of the grooves; further comprising a connecting assembly for rotating the arc rods to a preset position; and a positioning assembly for limiting the rotation of the arc rods.

[0005] Beneficial effects

[0006] This invention provides a portable training bow and arrow, which has the following advantages compared with the prior art:

[0007] In the initial state, both arc rods are retracted into the side of the handle. When assembling the arc rods, the user should attach the bowstring, which is adapted to the length of the handle and the assembled arc rods, to the rings at both ends. At this point, the user can manually rotate either arc rod. Since the bowstring is not yet taut, the arc rod can be rotated easily. During the rotation of the arc rod, the locking plate fixed to one side begins to rotate synchronously and gradually conforms to the surface of the stop bar. At this point, because the major and minor axes of the elliptical block are smaller than the major and minor axes of the elliptical groove, the user will find that the elliptical block's major and minor axes are smaller than those of the elliptical groove. Therefore, the elliptical block can now pass through the elliptical groove and adhere to the surface of the stop bar. The user should then rotate the elliptical block to ensure it rotates while adhering to the stop bar surface. Simultaneously, due to the damping rubber ring at the connection between the elliptical block and the clamping plate, the elliptical block is effectively prevented from rotating on its own without human intervention, and it stops rotating after rotating a certain degree. Since the major axis of the elliptical block is greater than the minor axis of the elliptical groove, the arc rod cannot continue to rotate, thus limiting its movement after it reaches the preset position. Subsequently, the user should... (The sentence is incomplete and requires further context to translate accurately.) Insert it into the limiting groove on the other side, and make the grooves on both sides of its output shaft fit against the protrusions on both sides of the inner wall of the limiting groove. At this time, the user can start the handheld motor while holding the handle and the handheld motor. At this time, the clamping plate will rotate at a constant speed under the drive of the handheld motor and fit against the stop bar. During this process, the arc rod begins to tighten the bowstring attached to its other end, so that the bowstring is tightened by the cooperation of the two arc rods. After the bowstring is tightened, the user should keep the handheld motor inserted in the limiting groove until the user rotates the elliptical block to make it clamp the plate. The bow is now in position, with both arc rods fixed to the ends of the handle. The user can then pull out the handheld motor and push the two square tubes so that the threaded bolts on them are positioned above the grooves on their corresponding arc rods. At this point, the rack fixed to the bottom of the square tubes meshes with the gear ring, further enhancing the limiting effect on the arc rods. The user can then rotate the bolts to engage them in the grooves on the arc rods, fixing the position of the square tubes on the arc rods and sealing the connection between the arc rods and the handle. This completes the bowstring installation during the bow assembly process. Attached Figure Description

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-4 This invention provides a portable training bow and arrow, comprising an arc rod 201, two arc rods 201 symmetrically rotatably connected to both sides of a handle 101, and a ring 202 slidably provided at the end of the arc rod 201 away from the handle 101, with a bowstring provided between the two rings 202. Square tubes 203 are slidably connected to both ends of the handle 101, and the square tubes 203 cover the arc rods 201. Bolts 204 are threaded onto the square tubes 203, and grooves are provided on the arc rods 201 corresponding to the bolts 204, with the bolts 204 fitting against the inner wall of the grooves.

[0016] It also includes a connecting component for rotating the arc rod 201 to a preset position; and a positioning component for limiting the rotation of the arc rod 201.

[0017] As those skilled in the art will know from the above examples, the handle 101 and other components in this application are made of carbon steel or other materials with high hardness. The purpose of this design is to increase their hardness and thus prevent them from breaking under stress.

[0018] Specifically, the positioning component includes a gear ring 206 and a rack 207. The gear ring 206 is fixedly connected to the arc rod 201, and the rack 207 is provided below the gear ring 206. When the bolt 204 slides to the groove of the arc rod 201, the rack 207 meshes with the gear ring 206. The rack 207 is fixedly connected to the square tube 203.

[0019] It also includes an adjustment component for adjusting the relative position of the ring 202 on the arc rod 201.

[0020] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific square tube 203 described in the above embodiments. For example, the square tube 203 may be provided with a soft rubber pad. The purpose of this arrangement is to facilitate the square tube 203 to fill the connection gap between it and the arc rod 201.

[0021] Specifically, the connecting component includes a retaining plate 208 and a stop bar 209. One side of the arc rod 201 extends through the handle 101, and the retaining plate 208 is fixedly connected to it. The retaining plate 208 is located at the center of the groove at the end of the handle 101, and the stop bar 209 is fixedly connected to the side wall of the groove at the end of the handle 101.

[0022] It also includes a limiting component for attaching the card plate 208 to the stop bar 209; and a driving component for rotating the card plate 208 at a constant speed.

[0023] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific handle 101 described in the above embodiments. For example, the handle 101 has a rubber grip on one side. The purpose of this arrangement is to make it easier for the user to hold.

[0024] Specifically, the limiting component includes an elliptical groove 301 and an elliptical block 302. The elliptical block 302 is rotatably connected to the card plate 208, and a damping rubber ring is provided at its connection point. The elliptical block 302 extends through the elliptical groove 301, which is disposed on the stop bar 209.

[0025] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific elliptical block 302 described in the above embodiments. For example, when the card plate 208 is attached to the elliptical groove 301, the elliptical block 302 passes through the elliptical groove 301 and is attached to the surface of the baffle 209.

[0026] Specifically, the major axis and minor axis of the elliptical block 302 are both smaller than the major axis and minor axis of the elliptical groove 301, and the major axis of the elliptical block 302 is larger than the minor axis of the elliptical groove 301.

[0027] Specifically, the drive assembly includes a limiting groove 304 and a handheld motor 303. The limiting groove 304 is provided at the axis of the card plate 208, and the side wall of the limiting groove 304 is symmetrically provided with protrusions. The output shaft of the handheld motor 303 is inserted into the limiting groove 304, and the output shaft of the handheld motor 303 is provided with a groove corresponding to the protrusions on the side wall of the limiting groove 304.

[0028] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific handheld motor 303 described in the above embodiments. For example, the handheld motor 303 should be a motor with multiple adjustable speeds and a self-locking effect. The purpose of this setting is to facilitate the driving of the arc rod 201 to rotate at a uniform speed.

[0029] Specifically, the adjustment component includes a connecting sleeve 305, on which the ring sleeve 202 is fixedly connected. The connecting sleeve 305 is fitted onto the arc rod 201, and a screw 306 is threaded onto the connecting sleeve 305. The arc rod 201 has multiple slots 307 arranged in an array, and the multiple slots 307 and the screw 306 are on the same circumference. The screw 306 fits against the inner wall of the slot 307. The user can adjust the distance between the two ring sleeves 202 by adjusting the relative position of the connecting sleeve 305 on the arc rod 201.

[0030] In this embodiment of the invention, both arc rods 201 are initially housed on the side of the handle 101. When assembling the arc rods 201, the user should attach the bowstring, which is adapted to the length of the handle 101 and the assembled arc rods 201, to the ring 202 at both ends. At this time, the user can manually rotate either arc rod 201. Since the bowstring is not yet taut, the arc rod 201 can be easily rotated. During the rotation of the arc rod 201, the locking plate 208 fixedly connected to one side of it begins to rotate synchronously and gradually adheres to the surface of the stop strip 209. At this time, since the major axis and minor axis of the elliptical block 302 are smaller than the major axis and minor axis of the elliptical groove 301, the arc rod 201 is rotated. The elliptical block 302 can then pass through the elliptical groove 301 and adhere to the surface of the stop bar 209. The user should then rotate the elliptical block 302 so that it adheres to the surface of the stop bar 209. Simultaneously, because a damping rubber ring is provided at the connection between the elliptical block 302 and the clamping plate 208, it effectively prevents the elliptical block 302 from rotating on its own without human intervention. The elliptical block 302 stops rotating after rotating 90°. Since the major axis of the elliptical block 302 is greater than the minor axis of the elliptical groove 301, the arc rod 201 cannot be rotated further. Therefore, the arc rod 201 is limited after rotating to the preset position. The user should then place the handheld motor 30... The output shaft of 3 is inserted into the limiting groove 304 on the other side, and the grooves on both sides of its output shaft fit against the protrusions on both sides of the inner wall of the limiting groove 304. At this time, the user can start the handheld motor 303 while holding the handle 101 and the handheld motor 303. At this time, the locking plate 208 rotates at a constant speed under the drive of the handheld motor 303 and fits against the stop bar 209. During this process, the arc rod 201 begins to tighten the bowstring attached to its other end, so that the bowstring is tightened by the cooperation of the two arc rods 201. After the bowstring is tightened, the user should keep the handheld motor 303 inserted in the limiting groove 304 until the user rotates the elliptical block 302 to make it engage the locking plate 208. The two arc rods 201 are now fixed at both ends of the handle 101. The user can then pull out the handheld motor 303 and push the two square tubes 203 so that the threaded bolts 204 are positioned above the grooves on the corresponding arc rods 201. At this time, the rack 207 fixed to the bottom of the square tube 203 meshes with the gear ring 206, further increasing the limiting effect on the arc rods 201. The user can then rotate the bolts 204 to lock them into the grooves on the arc rods 201, fixing the position of the square tubes 203 on the arc rods 201 and sealing the connection between the arc rods 201 and the handle 101. This completes the bowstring installation during the bow assembly process.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0033] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0034] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0035] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
