[0001] This utility model relates to the field of sports equipment technology, specifically to a bow. Background Technology
[0002] Existing bows or slingshots include a bow body with a bowstring mounted on it. For example, Chinese patent CN207922946U discloses a novel mounting and connection structure for the bow limbs and handle of a recurve bow, belonging to the field of bow and arrow accessories. It includes a handle, bow limbs, and a clamping screw. The handle has a limb mounting groove with raised sidewalls. The bow limbs have protrusions corresponding to the mounting groove and clamping screw holes. The clamping screw secures the bow limbs to the handle via clamping pads.
[0003] The above technical solution has the following disadvantages: 1. When in use, the user needs to pull the bowstring with their fingers to operate it, which is inconvenient and easy to injure the hand; 2. The arrow or bullet is directly ejected by the bowstring without guidance, which is inconvenient to aim and has low accuracy. Utility Model Content
[0004] The purpose of this invention is to provide a bow that addresses the above problems by making the bowstring easier to pull and improving accuracy.
[0005] To achieve the above objectives, this utility model discloses a bow, which includes a bow body, a bowstring mounted on the bow body, and a push-pull rod that can move forward and backward. The push-pull rod has a launch channel extending in the forward and backward direction, with the front end and both sides of the launch channel being open. The bowstring passes through the side of the launch channel, and an operating device for fixing and releasing the bowstring is mounted on the push-pull rod.
[0006] In use, initially, the push-pull lever is at the front of its stroke. First, use the operating device to secure the bowstring; then, pull the push-pull lever backward, simultaneously pulling the bowstring; finally, use the operating device to release the bowstring, which launches the arrow or projectile from the firing channel. The arrow or projectile can be placed in the firing channel before or after pulling the push-pull lever.
[0007] The advantages of this application are: 1. The combination of push-pull rod and operating device is used to pull and release the bowstring, which is easier to operate and less likely to injure the hand than the traditional method of pulling the bowstring directly with the fingers; 2. The arrow or projectile is launched through the launching channel and guided by the launching channel, which is convenient for aiming, has higher accuracy, and is conducive to improving the score.
[0008] Preferably, the bow body includes a main support, with movable arms hinged to both sides of the main support. A launching spring is connected between the movable arms and the main support. A first fixed pulley and a second fixed pulley are installed on the main support, and a movable pulley is installed on the movable arm. The end of the bowstring is connected to the main support or the movable arm, and passes through the launching channel after passing around the first fixed pulley, the movable pulley and the second fixed pulley in sequence.
[0009] When in use, the bowstring is pulled by the launch spring. Compared with the traditional elastic bow, the material requirements for the bow are lower, which helps to reduce costs. The combination of the first fixed pulley, the movable pulley and the second fixed pulley can reduce the force required to pull the bowstring and make it easier to operate.
[0010] Preferably, the bow body further includes a fixed arm fixedly installed on the side of the main support, a movable arm hinged to the fixed arm, a launching spring located between the movable arm and the fixed arm, and a first fixed pulley and a second fixed pulley located on the fixed arm.
[0011] The bow body uses a split design consisting of a main support, a fixed arm, and a movable arm, which facilitates processing and manufacturing.
[0012] Preferably, the main support includes two main support plates, and a main support positioning column is installed between the two main support plates; the fixed arm includes two fixed arm plates, and a fixed arm positioning column is installed between the two fixed arm plates; the movable arm includes two movable arm plates, and a movable arm positioning column is installed between the two movable arm plates.
[0013] The main support uses a combination of two main support plates, the fixed arm uses a combination of two fixed arm plates, and the movable arm uses a combination of two movable arm plates, which facilitates processing and manufacturing.
[0014] Preferably, the operating device includes a turntable rotatably connected to the push-pull rod and an operating rod hinged to the push-pull rod. The lower part of the turntable has a string groove for accommodating the bowstring, and the rear part of the turntable has a locking groove. The operating rod has a locking protrusion that cooperates with the locking groove, and an operating spring is connected between the upper part of the turntable and the operating rod.
[0015] In the initial state, the locking protrusion is engaged in the locking groove, and the string groove faces downwards. When the bowstring needs to be pulled backwards, first, the operating lever is moved, the locking protrusion disengages from the locking groove, and under the action of the operating spring, the turntable rotates, and the string groove faces downwards and forwards, facilitating the bowstring's entry into the string groove. Then, the operating lever is released, the turntable and operating lever return to their original positions, the locking protrusion re-engages in the locking groove, and the string groove faces downwards. At this point, pulling the push-pull lever backwards will not disengage the bowstring from the string groove. When the bowstring needs to be released, the operating lever is moved, the locking protrusion disengages from the locking groove, and under the action of the bowstring and the operating spring, the turntable rotates, and the string groove faces downwards and forwards, facilitating the bowstring's release from the string groove. The technical effect of fixing and releasing the bowstring can be achieved simply by moving the operating lever, making the operation simple.
[0016] Preferably, the turntable has a turntable limiting groove, and the push-pull rod is equipped with a turntable limiting pin that passes through the turntable limiting groove.

The push rod has a push rod positioning block on its side, and a push rod positioning groove is opened on the side of the storage slot. A projectile placement groove is provided on the lower side of the firing channel, and a feeding groove corresponding to the feeding port is opened at the front of the turntable.
[0019] When loading projectiles, first, push the top rod forward and rotate it so that the top rod positioning block engages with the top rod positioning groove, preventing the top rod from retracting. Then, put several projectiles into the storage tank through the loading port. Finally, rotate the top rod so that the top rod positioning block disengages from the top rod positioning groove. The top rod retracts under the action of the top rod spring, pushing the projectiles to the rear end of the storage tank.
[0020] In the initial state, the feed slot faces downward and forward, and the projectile does not enter the feed port. When using a projectile, first, the operating lever is moved, the locking protrusion disengages from the locking groove, and under the action of the operating spring, the turntable rotates, the feed slot faces forward, and a projectile enters the feed port. Then, the turntable and operating lever are reset, and the projectile enters the firing channel through the feed port along with the feed slot. The projectile placement slot is used to prevent the projectile from rolling back and forth in the firing channel.
[0021] The turntable and push-pull rod of this structure can simultaneously achieve the technical effects of fixing and releasing the bowstring and feeding ammunition, making it simple to operate and convenient to use. Preferably, the push-pull rod includes an upper rod body and a lower rod body. The lower side of the upper rod body has an upper firing groove, and the upper side of the lower rod body has a lower firing groove. The gap between the upper and lower rod bodies, the upper firing groove, and the lower firing groove constitute the firing channel.
[0022] The push-pull rod consists of an upper rod and a lower rod, and adopts a split design for easy processing and manufacturing.
[0023] Preferably, the lower side of the upper rod has an upper rod positioning groove extending in the left and right directions, and the upper side of the lower rod has a lower rod positioning groove extending in the left and right directions. A rod positioning pin is placed between the upper rod positioning groove and the lower rod positioning groove. The front end of the upper rod and the front end of the lower rod are fixed together by a front hoop, and the rear end of the upper rod and the rear end of the lower rod are fixed together by a rear hoop.
[0024] The upper rod positioning groove, lower rod positioning groove, and rod positioning pin work together to position the upper and lower rods in the front and rear directions. The front and rear hoops are used for positioning the sides of the rods and lower rods. The structure is simple, reliable, and has low manufacturing cost.
[0025] Preferably, a handle is installed on the bow body. During use, the operator can hold the handle, making operation simple.
[0026] Preferably, a push-pull rod limiting plate is installed on the push-pull rod. When the push-pull rod is pulled backward and the limiting plate contacts the bow body, the push-pull rod is stopped from being pulled backward any further.
[0027] Preferably, the bow body is equipped with a push-pull rod guide wheel for cooperating with the push-pull rod. The push-pull rod guide wheel helps to ensure smooth movement of the push-pull rod.
[0028] In summary, the beneficial effects of this utility model are as follows: In use, initially, the push-pull rod is located at the front end of its stroke. First, the bowstring is fixed using the operating device; then, the push-pull rod is pulled backward, simultaneously pulling the bowstring; finally, the bowstring is released using the operating device, launching the arrow or projectile from the firing channel. The arrow or projectile can be placed in the firing channel before or after the push-pull rod is pulled.

[0049] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0050] like Figures 1 to 3 As shown, a bow includes a bow body with a bowstring 5 mounted on it. A push-pull rod 10 capable of moving forward and backward is mounted on a main support 1. The push-pull rod 10 has a launch channel 1007 extending in the forward and backward direction. The front end and both sides of the launch channel 1007 are open. The bowstring 5 passes through the side of the launch channel 1007. An operating device for fixing and releasing the bowstring 5 is mounted on the push-pull rod 10. A handle is mounted on the push-pull rod 10 for easy pulling the push-pull rod 10 backward.
[0051] In use, initially, the push-pull rod 10 is at the front of its stroke. First, the bowstring 5 is secured using the operating device. Then, the push-pull rod 10 is pulled backward, simultaneously pulling the bowstring 5. Finally, the bowstring 5 is released using the operating device, launching the arrow or projectile from the firing channel 1007. The arrow or projectile can be placed in the firing channel 1007 before or after the push-pull rod 10 is pulled.
[0052] The advantages of this application are: 1. The combination of push-pull rod 10 and operating device is used to pull and release the bowstring 5, which is easier to operate and less likely to injure the hand than the traditional method of directly pulling the bowstring 5 by hand; 2. The arrow or projectile is launched through the launching channel 1007 and guided by the launching channel 1007, which is convenient for aiming, has higher accuracy, and is conducive to improving the performance.
[0053] Specifically, a handle 11 is installed on the bow body. During use, the operator can hold the handle 11, making operation simple. A push-pull rod limiting plate 1005 is installed on the push-pull rod 10. When the push-pull rod 10 is pulled backward, the push-pull rod limiting plate 1005 contacts the bow body, stopping further backward pulling of the push-pull rod 10. A push-pull rod guide wheel 105 is installed on the bow body to cooperate with the push-pull rod 10. The push-pull rod guide wheel 105 helps ensure smooth movement of the push-pull rod 10.
[0054] The bow includes a main support 1, with movable arms 3 hinged to both sides of the main support 1. A launching spring 4 connects the movable arms 3 to the main support 1. A first fixed pulley 7 and a second fixed pulley 9 are mounted on the main support 1, and a movable pulley 8 is mounted on the movable arms 3. The end of the bowstring 5 is connected to either the main support 1 or the movable arms 3, and passes sequentially around the first fixed pulley 7, the movable pulley 8, and the second fixed pulley 9 before passing through the launching channel 1007. In use, the launching spring 4 provides tension to the bowstring 5. Compared to traditional elastic bows, this design places lower demands on the bow's material, reducing costs. The combination of the first fixed pulley 7, the movable pulley 8, and the second fixed pulley 9 reduces the force required to pull the bowstring 5, facilitating operation.
[0055] Specifically, the bow body also includes a fixed arm 2 fixedly installed on the side of the main support 1, a movable arm 3 hinged to the fixed arm 2, a launching spring 4 located between the movable arm 3 and the fixed arm 2, and a first fixed pulley 7 and a second fixed pulley 9 located on the fixed arm 2. The bow body uses a split design of the main support 1, fixed arm 2 and movable arm 3, which facilitates processing and manufacturing.
[0056] The main support 1 includes two main support plates 101, with a main support positioning column 102 installed between the two main support plates 101. A main support fixing bolt 103 passes through the two main support plates 101 and the main support positioning column 102 and is connected to the main support fixing nut. Several main support positioning plates 104 are also installed between the two main support plates 101. The fixed arm 2 includes two fixed arm plates 201, with a fixed arm positioning column 202 installed between the two fixed arm plates 201. A fixed arm fixing bolt 203 passes through the two fixed arm plates 201 and the fixed arm positioning column 202 and is connected to the fixed arm fixing nut. The movable arm 3 includes two movable arm plates 301, with a movable arm positioning column 302 installed between the two movable arm plates 301. A movable arm fixing bolt 303 passes through the two movable arm plates 301 and the movable arm positioning column 302 and is connected to the movable arm fixing nut. A bowstring connecting bolt 6 is also installed between the two main support plates 101 and the two fixed arm plates 201 or the two movable arm plates 301. The end of the bowstring 5 is connected to the bowstring connecting bolt 6. In this embodiment, the bowstring connecting bolt 6 is located between the two movable arm plates 301. The main support 1 uses a combination of two main support plates 101, the fixed arm 2 uses a combination of two fixed arm plates 201, and the movable arm 3 uses a combination of two movable arm plates 301, which facilitates processing and manufacturing.
[0057] like Figure 4 , Figure 6 As shown, the operating device includes a turntable 1020 rotatably connected to the push-pull rod 10 and an operating rod 1006 hinged to the push-pull rod 10. The lower part of the turntable 1020 is provided with a string groove 1022 for accommodating the bowstring 5, and the rear part of the turntable 1020 is provided with a locking groove 1019. The operating rod 1006 has a locking protrusion 1018 that cooperates with the locking groove 1019. An operating spring 1017 is connected between the upper part of the turntable 1020 and the operating rod 1006. In the initial state, the locking protrusion 1018 is engaged with the locking groove 1019, and the bowstring groove 1022 faces downward. When it is necessary to pull the bowstring 5 backward, firstly, the operating lever 1006 is moved, the locking protrusion 1018 disengages from the locking groove 1019, and under the action of the operating spring 1017, the turntable 1020 rotates, and the bowstring groove 1022 faces downward and forward, facilitating the bowstring 5 to enter the bowstring groove 1022. Then, the operating lever 1006 is released, the turntable 1020 and the operating lever 1006 return to their original positions, and the locking protrusion 1018 re-engages in the locking mechanism. With the groove 1019 and the string groove 1022 facing downwards, when the push-pull rod 10 is pulled backwards, the bowstring 5 will not disengage from the string groove 1022. When it is necessary to release the bowstring 5, the operating rod 1006 is moved, and the locking protrusion 1018 disengages from the locking groove 1019. Under the action of the bowstring 5 and the operating spring 1017, the turntable 1020 rotates, and the string groove 1022 faces downwards and forwards, making it easier for the bowstring 5 to disengage from the string groove 1022. The technical effect of fixing and releasing the bowstring 5 can be achieved simply by moving the operating rod 1006, making the operation simple.
[0058] The turntable 1020 has a turntable limiting groove 1023, and the push-pull rod 10 is equipped with a turntable limiting pin 1024 that passes through the turntable limiting groove 1023. The turntable limiting groove 1023 and the turntable limiting pin 1024 cooperate to limit the rotation angle of the turntable 1020, which is convenient to use.
[0059] like Figures 4 to 9 As shown, the push-pull rod 10 has a storage slot 1008, which has a loading port 1009 that communicates with the outside and a feed port 1025 that communicates with the firing channel 1007. A push rod 1010 is slidably connected inside the storage slot 1008. A push rod spring 1011 is placed between the push rod 1010 and the storage slot 1008. The push rod 1010 has a push rod positioning block 1012 on its side. The storage slot 1008 has a push rod positioning groove 1013 on its side. The firing channel 1007 has a projectile placement groove 1028 on its lower side. The turntable 1020 has a feed groove 1021 at its front that corresponds to the feed port 1025. When loading projectiles, firstly, push the top rod 1010 forward and rotate it so that the top rod positioning block 1012 engages with the top rod positioning groove 1013, preventing the top rod 1010 from retracting. Then, several projectiles are placed into the storage tank 1008 through the loading port 1009. Finally, rotate the top rod 1010 so that the top rod positioning block 1012 disengages from the top rod positioning groove 1013. The top rod 1010 retracts under the action of the top rod spring 1011, pushing the projectiles toward the rear end of the storage tank 1008. In the initial state, the feed groove 1021 faces downward and forward, and the projectile does not enter the feed port 1025. When using a projectile, firstly, the operating lever 1006 is moved, the locking protrusion 1018 disengages from the locking groove 1019, and under the action of the operating spring 1017, the turntable 1020 rotates, the feed groove 1021 faces forward, and a projectile enters the feed port 1025. Then, the turntable 1020 and the operating lever 1006 return to their original positions, and the projectile, along with the feed groove 1021, enters the firing channel 1007 through the feed port 1025. The projectile placement groove 1028 is used to prevent the projectile from rolling back and forth within the firing channel 1007. This structure, with the turntable 1020 and the push-pull lever 10 combined, can simultaneously achieve the technical effects of fixing and releasing the bowstring 5 and feeding projectiles, making it simple to operate and convenient to use.
[0060] Specifically, the push-pull rod 10 includes an upper rod body 1001 and a lower rod body 1002. The upper rod body 1001 has an upper launching groove 1026 on its lower side, and the lower rod body 1002 has a lower launching groove 1027 on its upper side. The gap between the upper rod body 1001 and the lower rod body 1002, the upper launching groove 1026, and the lower launching groove 1027 constitute a launching channel 1007. Both the upper rod body 1001 and the lower rod body 1002 are made of aluminum profiles, resulting in low manufacturing costs. The push-pull rod 10, including the upper rod body 1001 and the lower rod body 1002, adopts a split design, which facilitates processing and manufacturing.
[0061] Specifically, the upper rod 1001 has an upper rod positioning groove 1014 extending in the left and right directions on its lower side, and the lower rod 1002 has a lower rod positioning groove 1015 extending in the left and right directions on its upper side. A rod positioning pin 1016 is placed between the upper rod positioning groove 1014 and the lower rod positioning groove 1015. The front end of the upper rod 1001 and the front end of the lower rod 1002 are fixed together by a front clamp 1003, and the rear end of the upper rod 1001 and the rear end of the lower rod 1002 are fixed together by a rear clamp 1004. The upper rod positioning groove 1014, the lower rod positioning groove 1015, and the rod positioning pin 1016 cooperate to position the upper rod 1001 and the lower rod 1002 in the front and rear directions. The front clamp 1003 and the rear clamp 1004 are used for positioning the sides of the rod 101 and the lower rod 1002. The structure is simple and reliable, and the manufacturing cost is low.
[0062] The above description is only a preferred embodiment of the present utility model.
