Description

Technical Field

[0001] The invention relates to the technical field of bow accessories, in particular to an arrow stand for placing arrow shafts. Background Art

[0002] The arrow rest is an auxiliary component used to support the arrow shaft until the arrow is shot. Since the support of the arrow rest can reduce the swing of the arrow, improve the stability of the arrow during flight and the accuracy of the arrow, most bows are currently equipped with arrow rests, and there are many types of arrow rests. Among them, the drop-down arrow rest is deeply loved by hunters because of its high precision and ability to reduce friction with the arrow during the shooting process. For example, the document with Chinese patent authorization announcement number CN20235066U discloses such an arrow rest, which includes a base, a rotating shaft supported on the base and a bracket arranged on the rotating shaft. The upper end of the bracket has a notch for the arrow shaft to rest on. The rotating shaft is provided with a torsion spring with two ends respectively positioned on the base and the bracket to keep the bracket upright. At the same time, a cantilever is also provided on the rotating shaft. The outward end of the cantilever is fixed to one end of a pull rope, and the other end of the pull rope is tied to the bow handle. A stop arm is provided on the base. When the bracket is in an upright state, the stop arm resists the above-mentioned cantilever, and when the bow handle is in a natural state, the pull rope is tightened and the bracket tilts forward. When in use, the bowstring is pulled backwards and the bow handle deflects toward the center side of the bow body. At this time, the drawstring is slack, and the rotating shaft rotates under the action of the restoring force of the torsion spring, driving the bracket and the cantilever to rotate until the cantilever is supported by the blocking arm. At this time, the bracket is in an upright state, and at the moment of releasing the bowstring, the bow handle is reset and the drawstring is pulled to make the drawstring in a taut state. At this time, the drawstring rotates the rotating shaft through the cantilever, the torsion spring stores energy, and the bracket tilts forward again. Therefore, the arrow rest can automatically cooperate with archery to avoid friction between the arrow and the bracket at the moment of shooting, thereby achieving the purpose of improving shooting accuracy and stability while facilitating operation.

[0003] However, it is found during use that the bracket can only stand upright after the bowstring is pulled back to relax the drawstring, and then the arrow shaft can be placed for aiming. In actual operation, there is a need to stand upright before the bowstring is pulled, so as to place the arrow shaft for trial aiming. At this time, no force is applied to the bowstring, which is more conducive to aiming, so that the hunter can quickly aim at the prey after pulling the bowstring. Therefore, the existing arrow rest needs to be further improved. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an arrow rest with a novel structure, which is conducive to aiming before pulling the bowstring and can improve shooting accuracy, with respect to the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: an arrow rest capable of improving shooting accuracy, comprising:

[0006] A base, wherein a through hole is formed on the base;

[0007] A main shaft, one end of which is supported in the through hole so that the main shaft can rotate relative to the base, and the other end of the main shaft is exposed outside the through hole;

[0008] A bracket is fixed on the main shaft exposed on the base, and a recess is formed on the bracket for the arrow shaft to rest on;

[0009] A first torsion spring, sleeved on the main shaft, enables the bracket to always have an upright tendency;

[0010] Pull rope;

[0011] It is characterized by also including:

[0012] A secondary shaft, which is coaxially distributed with the main shaft, one end of which is connected to one end of the main shaft through a connecting structure, the connecting structure enables the secondary shaft and the main shaft to rotate together and enables the secondary shaft to move axially relative to the main shaft, and the other end of the secondary shaft is exposed from the base to become an operating end;

[0013] A positioning pin, which is distributed parallel to the secondary shaft and is linked to the secondary shaft;

[0014] A rotating wheel, which is loosely sleeved on the secondary shaft, and has a positioning hole for inserting the positioning pin on one end surface of the rotating wheel, and the rotating wheel is connected to the pull rope;

[0015] A second torsion spring, sleeved on the secondary shaft, enables the rotating wheel to always have a tendency to return to the original position when the pull rope is not stressed;

[0016] A spring, sleeved on the secondary shaft, so that the secondary shaft always has a tendency to move axially so that the positioning pin is close to the end surface of the rotating wheel where the positioning hole is opened;

[0017] The first torsion spring, the second torsion spring and the spring are in a natural state, and the positioning pin is inserted into the positioning hole.

[0018] In the above solution, preferably, the connection structure includes a radially arranged connection seat located on one end of the secondary shaft and a groove opened on the end surface of one end of the primary shaft, the connection seat is axially inserted into the groove, and the distance that the connection seat is allowed to axially move in the groove is not less than the distance that the positioning pin is axially moved in the positioning hole, so that the overall transmission is stable and the processing and assembly are convenient.

[0019] In the above preferred solution, it is further preferred that there are two positioning pins, both of which are fixed on the connecting seat and are respectively located on both sides of the secondary shaft, so that the secondary shaft is evenly stressed when connected to the rotating wheel.

[0020] In the above further preferred scheme, a further improvement is that two arc-shaped long grooves are opened on one end face of the rotating wheel and are respectively connected with each positioning hole. After the positioning pin is separated from the positioning hole, it slides in the respective arc-shaped long grooves, so that the secondary shaft and the rotating wheel can rotate smoothly relative to each other, and can ensure that the positioning pin is smoothly inserted into the positioning hole.

[0021] In order to reduce noise and extend service life, it is better that each of the arc-shaped long grooves is also fixed with an impact-resistant strip, and when the bracket is in an upright state, the positioning pin is against the corresponding impact-resistant strip.

[0022] In the above schemes, a further improvement is that an end cover covering one port of the through hole is fixed on the base, and an operating part is fixed to the other end of the secondary shaft after passing through the end cover, and the two ends of the spring are respectively connected to the end cover and the operating part to facilitate assembly.

[0023] Preferably, two ends of the second torsion spring are respectively connected to the rotating wheel and the end cover.

[0024] In order to prevent the rotating wheel from over-rotating, a limiting column is fixed on the other end surface of the rotating wheel, and a limiting groove for the limiting column to slide is opened on the inner wall of the end cover.

[0025] Similarly, in order to reduce noise during use and extend the service life, elastic strips that can resist the limiting pillars are respectively fixed at both ends of the limiting groove.

[0026] In order to facilitate the connection with the pull rope, a lug is provided on the rotating wheel, and a notch extending along the circumferential direction for the lug to extend outward is opened on the end cover, and the pull rope is fixed on the lug.

[0027] Similarly, in order to prevent the main shaft from rotating excessively, a radial pin is fixed on the main shaft, and the other end of the through hole axially extends a first stop portion and a second stop portion distributed at intervals along the circumferential direction. When the bracket is in an upright state, the radial pin abuts against the first stop portion, and when the bracket is in a horizontal state, the radial pin abuts against the second stop portion.

[0028] Compared with the prior art, the present invention adds a secondary shaft, a rotating wheel, a second torsion spring and a spring, and sets a connecting structure between the rotating wheel and the secondary shaft. Therefore, in a natural state, the secondary shaft, the rotating wheel, the main shaft and the bracket are linked to each other. Once the drawstring is tightened, there is no need to pull the bowstring. As long as force is applied to the secondary shaft to disengage the positioning pin from the positioning hole on the rotating wheel, the bracket can be made to stand upright under the action of the first torsion spring to meet the aiming requirement before the bowstring is pulled. After the bowstring is pulled, due to the relaxation of the drawstring, the rotating wheel is reset under the action of the second torsion spring, and the positioning pin is inserted into the positioning hole again under the action of the spring. As in the prior art, the bracket becomes horizontal at the moment the arrow is shot. Therefore, the present invention can meet the need for mid-course aiming while meeting the normal archery requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention is further described in detail below with reference to the accompanying drawings.

[0046] like Figures 1 to 16 As shown in FIG. 1 , a preferred embodiment of the arrow rest of the present invention is shown. The arrow rest comprises a base 1, a main shaft 2a, a bracket 3, a secondary shaft 2b, a first torsion spring 4a, a rotating wheel 5, a positioning pin 6, a second torsion spring 4b and a spring 4c, wherein the base is used to be fixed on the bow body. In order to flexibly adjust the position of the base 1 relative to the bow body, the base is also positioned on the bow body through a slide 30 and a bracket 40 as in the prior art, that is, the bracket 40 is provided with a long hole 401 in the front and rear directions, and the first bolt a1 is passed through the long hole 401 to position the bracket 40 on the bow body. When necessary, the base 1 is fixed on the bow body through the front and rear slides. Move the bracket 40 to adjust the front and rear position of the base 1 relative to the bow body, and then tighten the first bolt a1; a screw-nut substructure b is provided between the slide 30 and the bracket 40, and the upper and lower positions of the slide 30 relative to the bracket 40 can be adjusted by rotating the screw rod, and the second bolt a2 is used to clamp and position the slide 30 after it is adjusted into place; similarly, a screw-nut substructure b is provided between the base 1 and the slide 30, and the horizontal position of the base 1 relative to the slide 30 can be adjusted by rotating the screw rod, and the third bolt a3 is used to clamp and position the base 1 after the base 1 is moved into place. In other words, the base 1 can be adjusted in the up-down, horizontal, and front-to-back directions relative to the bow body through the slide 30 and the bracket 40. Since the slide 30, the bracket 40, and the screw-nut substructure b are all prior art, the detailed structure of the specific movement, clamping, and positioning will not be described in detail. A through hole 11 is provided on the base 1, and in this embodiment, from Figure 4 and Figure 5It can be seen that the through hole 11 is a stepped hole composed of four aperture sections with different inner diameters, that is, from the large diameter hole to the small diameter hole, they are the first aperture section 11a, the second aperture section 11b, the third aperture section 11c and the fourth aperture section 11c respectively, the port of the first aperture section 11a (that is, one port of the through hole) is covered by the end cover 7, and the port of the fourth aperture section 11d (that is, the other port of the through hole) faces the bracket 3.

[0047] One end of the main shaft 2a is supported in the through hole 11 of the base 1, and the other end of the main shaft 2a is exposed in the through hole 1, so that the main shaft 2a can rotate relative to the base 1. Specifically, in order to ensure that the main shaft 2a can rotate flexibly relative to the base 1 and to achieve connection with the secondary shaft 2b, one end of the main shaft 2a has a larger diameter and is supported on the first aperture section 11a of the through hole through the first bearing c1, and the middle part is supported on the third aperture section 11c through the second bearing c2, and the fourth aperture section 11d is for the main shaft 2a to pass through and be exposed. In order to limit the rotation angle of the main shaft 2a relative to the base 1, a radial pin 21a is fixed on the main shaft 2a, and the port of the fourth aperture section 11d axially extends a first stop 12 and a second stop 13 distributed at intervals along the circumferential direction.

[0048] The bracket 3 is fixed on the main shaft 2a exposed on the base 1, and a recess 31 is formed on the bracket 3 for the arrow shaft to rest on; that is, the bracket 3 can rotate relative to the base 11 together with the main shaft 2a. When the bracket 3 is in an upright state, the radial pin 21a abuts against the first stopper 12 (see FIG. Figure 2 ), when the bracket 3 is in a horizontal state, the radial pin 21a abuts against the second stopper 13 (see Figure 7 ).

[0049] The first torsion spring 4a is sleeved on the main shaft 2a and is located on the second aperture section 11 of the through hole. One end of the first torsion spring 4a is positioned on the inner wall of the base 1, and the other end is positioned on the main shaft 2a, so that the main shaft 2a always has a tendency to rotate, and finally the bracket 3 always has a tendency to stand upright.

[0050] The auxiliary shaft 2b is coaxially distributed with the main shaft 2a. One end of the auxiliary shaft 2b is connected to one end of the main shaft 2a through a connecting structure. The connecting structure enables the auxiliary shaft 2b to rotate with the main shaft 2a and enables the auxiliary shaft 2b to move axially relative to the main shaft 2a. The other end of the auxiliary shaft 2b passes through the end cover 7 and is exposed on the base 1 to become an operating end. In this embodiment, the connecting structure includes a radially arranged connecting seat 21b located on one end of the auxiliary shaft 2b and a groove 22a opened on the end surface of one end of the main shaft 2a. In order to enable the auxiliary shaft 2b and the main shaft 2a to rotate together, the cross section of the connecting seat 21b is non-circular, and the cross section of the groove 22a matches the cross section of the connecting seat. Figure 8 , 9As can be seen in the figure, the connection seat 21b is a long strip with a convex middle portion, and correspondingly, the cross section of the groove 22a is a waist-shaped hole with a convex middle portion (see Figure 6 ), the connection seat 21b can be axially inserted into the groove 22a, and has space for axial movement in the groove 22a, that is, the distance that the groove 22a allows the connection seat 21b to move axially is not less than the distance that the positioning pin 6 described below moves axially in the positioning hole 51. That is, the groove 22a has enough depth, so that after the connection seat 21b moves in the groove 22a, it can drive the positioning pin 6 to leave the rear positioning hole 51.

[0051] The positioning pin 6 is parallel to the secondary shaft 2b and is linked with the secondary shaft 2b. In order to make the overall structure compact, the positioning pin 6 is fixed on the connecting seat 21b, and there are two of them, which are respectively located on both sides of the secondary shaft 2b, so that the force is more uniform.

[0052] The rotating wheel 5 is located in the joint cavity between the end cover 7 and the base 1, and is loosely sleeved on the secondary shaft 2b, that is, the rotating wheel 5 can rotate relative to the secondary shaft 2b. A positioning hole 51 for inserting the positioning pin 6 is opened on one end face of the rotating wheel 5 (the end face facing the first aperture section 11 in the figure). Since there are two positioning pins 6, there are also two positioning holes 51. That is, when the positioning pin 6 is located in the positioning hole 51, the rotating wheel 5 is connected with the secondary shaft 2b, the main shaft 2a, and the bracket 3 as a whole. The rotating wheel 5 is connected to one end of the pull rope 10, and the other end of the pull rope 10 is used to be tied to the bow arm. Here, in order to facilitate the connection with the pull rope 10 and not hinder the rotation of the rotating wheel 5, a lug 52 is provided on the rotating wheel 5, and a notch 71 extending along the circumferential direction for the lug 52 to extend outward is opened on the end cover 7, and the pull rope 10 is fixed on the lug 52. When the positioning pin 6 is located in the positioning hole 51, when the pull rope 10 is subjected to external force, the rotating wheel 5 can drive the secondary shaft 2b, the main shaft 2a and the bracket 3 to rotate together.

[0053] The second torsion spring 4b is sleeved on the secondary shaft 2b, one end of the second torsion spring 4b is positioned on the rotating wheel 5, and the other end is positioned on the end cover 7, so that the rotating wheel 5 always has a tendency to return to the original position when the pull rope 10 is not under force, that is, Figure 6 The trend of the position state shown by the rotating wheel 5.

[0054] The above-mentioned spring 4c is sleeved on the secondary shaft 2b located on the outside of the end cover 7. For the convenience of operation, an operating part 8 is fixed on the operating end of the secondary shaft 2b. The operating part 8 can be in the form of a handle or a knob. The spring 4c is a compression spring with one end against the end cover 7 and the other end against the operating part 8, so that the secondary shaft 2b always has a tendency to move axially outward (that is, to the operating part side) so that the positioning pin 6 is close to the end face of the rotating wheel 5 where the positioning hole 51 is located.

[0055] In order to ensure that the two positioning pins 6 can be smoothly inserted into the corresponding positioning holes 51, two arc-shaped long grooves 53 are also opened on one end surface of the rotating wheel 5, which are respectively connected with the positioning holes 51. When the positioning pins 6 are separated from the positioning holes 51, the secondary shaft 2b, the main shaft 2a and the bracket 3 rotate relative to the rotating wheel 5 under the action of the first torsion spring 4a, and the positioning pins 6 slide in the respective arc-shaped long grooves 53 until they hit the end edge of the arc-shaped long grooves 53. At this time, in order to reduce the noise during the collision and protect the rotating wheel 5 at the same time, an impact-resistant strip 9a is fixed at the end of each arc-shaped long groove. The impact-resistant strip 9a can be a rubber rod, that is, when the positioning pins 6 are separated from the positioning holes 51, when the bracket 3 is in an upright state, the positioning pins 6 and the corresponding impact-resistant strips 9a are against each other.

[0056] At the same time, in order to prevent the rotating wheel 5 from over-rotating, a limiting column 54 is fixed on the other end face of the rotating wheel 5, and a limiting groove 72 for the guide column 54 to slide is opened on the inner wall of the end cover 7. Similarly, elastic strips that can resist the limiting column 54 are respectively fixed at both ends of the limiting groove 72, that is, Fig. 9 The first elastic strip 9b and the second elastic strip 9c in the embodiment may also be rubber bars, which can also reduce the noise when colliding with the limiting column 54.

[0057] A barrier rod 20 is also fixed on the base 1. The barrier rod 20 is roughly in an inverted Z shape, with the lateral portion of its lower end fixed on the base 1 and the lateral portion of its upper end located above the groove 31 of the bracket 3. In addition to playing a safety role, it also has a shock-absorbing effect.

[0058] When the arrow rest is not mounted on the bow, the first torsion spring 4a, the second torsion spring 4b and the spring 4c are in a natural state, and the positioning pin 6 is inserted into the positioning hole 51. Figures 1 to 6 That is, at this time, the rotating wheel 5 is integrated with the secondary shaft 2b, the main shaft 2a and the bracket 3. Under the action of the first torsion spring 4a, the bracket 3 is in an upright state, and the lug on the rotating wheel 5 is in Figure 3 In the first position I, the radial pin 21 a on the main shaft 2 a abuts against the first stop portion 12 .

[0059] After the arrow rest is mounted on the bow, the desired position of the base 1 is adjusted by the screw nut substructure b between the slide 30 and the bracket 40 and the screw nut substructure b between the slide 30 and the base 1, and then the other end of the drawstring 10 is tied to the bow arm to tighten the drawstring 10. That is, at this time, the drawstring 10 applies force to the rotating wheel 5, so that the rotating wheel 5 overcomes the force of the first torsion spring and the second torsion spring 4b, and drives the secondary shaft 2b and the main shaft 2a and the bracket 3 to press together. Figure 3 The bracket 3 is rotated in the direction indicated by the middle arrow (clockwise) until the limiting column 54 abuts against the second elastic strip 9c. At this time, the bracket 3 falls down and is in a horizontal state. Figures 7 to 12At this time, the lug 52 rotates to Fig.10 The second position II shown. The positioning pin 6 on the main shaft 2a abuts against the second stop 13, see Figure 7 .

[0060] Next, place the arrow on the bracket 3, press the operating part 8, overcome the force of the spring 4c, and make the secondary shaft 2b drive the positioning pin 6 to move axially inward (toward the bracket 3), see Fig.13 and Fig.14 At the same time, the connecting seat 21b drives the positioning pin 6 to move axially in the groove 22a toward the bottom side of the groove 22a, so that the positioning pin 6 is disengaged from the positioning hole 51, that is, the rotating wheel 5 is disengaged from the secondary shaft 2b and is no longer constrained by the tightened pull rope 10. At this time, under the action of the first torsion spring 4a, the main shaft 2a drives the secondary shaft 2b and the bracket 3 to rotate together. Fig.10 The bracket 3 rotates in the direction indicated by the arrow in the figure, and is in an upright state again, until the radial pin 21a on the main shaft 2a abuts against the first stop portion 12.

[0061] Next, when the bow is drawn, the distance between the bow arms will decrease, and the drawstring 10 tied to the bow arms will also become loose. At this time, the rotating wheel 5 will press the second torsion spring 4b under the force. Fig.10 The locating hole 51 on the rotating wheel 5 is aligned with the locating pin 6, that is, they are on the same straight line. Under the action of the spring 4c, the locating pin 6 enters the locating hole 51 of the rotating wheel 5. That is, at this time, the rotating wheel 5 is integrated with the secondary shaft 2b, the main shaft 2a and the bracket 3, and the arrow rest is restored to the initial state.

[0062] When the arrow is shot, the bow arm is reset, which pulls the drawstring 10 to tighten the drawstring 10 again. In this process, the drawstring 10 pulls the rotating wheel 5 to press Figure 3 The auxiliary shaft 2b, the main shaft 2a and the bracket 3 are rotated together again until the bracket 3 is in a horizontal state, that is, it returns to the horizontal state. Figures 7 to 12 state, thus avoiding friction between the arrow and the bracket 3 at the moment of shooting.

[0063] In addition to the above embodiments, those skilled in the art can imagine that the connection structure between the secondary shaft 2b and the main shaft 2a can adopt the existing keyway connection structure. In this case, the through hole does not need to adopt the stepped hole with multiple apertures in this embodiment. Similarly, the positioning pin can also be fixed to other parts of the secondary shaft through other connecting parts, such as the middle part of the secondary shaft. Correspondingly, the positioning hole on the rotating wheel 5 can be set on the other end face of the rotating wheel 5. In this case, the spring 4c can be a tension spring. The base can also adopt a structure of upper and lower halves combined to eliminate the end cover, and the two ends of the first torsion spring can be positioned on the base and the bracket respectively. That is, such a scheme also belongs to the protection scope of the present invention.
