DETAILED DESCRIPTION
[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 5 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.
[0025] Figure 1 It is a schematic diagram of the installation of an embodiment of a structure for connecting a bow piece seat and a bow handle of the utility model; Figure 2 It is an installation cross-sectional view of an embodiment of a structure for connecting a bow piece seat and a bow handle of the utility model; Figure 3 FIG. 1 is a structural diagram of an embodiment of a structure for connecting a bow piece seat and a bow handle according to the utility model. Figure 1 , Figure 2 as well as Figure 3 As shown, the structure of connecting the limb seat 1 and the handle 2 provided in this embodiment hinges one end of the limb seat 1 to one side of one end of the handle 2, so that the limb seat 1 can be stably connected to the handle 2 and can also deflect relative to the handle 2, providing conditions for subsequent adjustment of the limb. At this time, an adjustment screw 3 is arranged between the other end of the limb seat 1 and the other side of the corresponding end of the handle 2. When in use, the user can loosen or tighten the limb seat 1 and the handle 2 by turning the adjustment screw 3, thereby adjusting the installation angle of the limb seat 1 on the handle 2 to meet different usage requirements. In addition, the structure of connecting the limb seat 1 and the handle 2 provided in this embodiment also includes an adjustment part 4 and an indication part 5.
[0026] Specifically, one end of the adjusting part 4 is connected to the limb seat 1, so that the adjusting part 4 can move with the adjustment of the limb seat 1, and at the same time, the other end of the adjusting part 4 is extended toward the handle 2 and an adjusting scale 411 is provided on the extended end thereof, so that the adjusting part 4 can cooperate with the handle 2, and when the adjusting part 4 moves with the limb seat 1, the adjusting scale 411 can also move relative to the handle 2, providing conditions for the subsequent intuitive reflection of the adjustment data. At the same time, an indicating part 5 corresponding to the adjusting scale 411 is also provided on the handle 2, so that when adjusting, the limb seat 1 deflects relative to the handle 2, so that the limb seat 1 drives the adjusting part 4 to move relative to the handle 2, so that the adjusting scale 411 on the adjusting part 4 moves relative to the indicating part 5 on the handle 2, and according to the front and back changes of the indicating part 5 relative to the adjusting scale 411, the adjustment situation is intuitively reflected, which is convenient for the user to adjust once, without repeated adjustment, and the adjustment is more accurate and efficient, and the convenience of use is higher. It is worth pointing out that one end of the adjusting portion 4 can also be connected to the bow handle 2, that is, the installation position of the adjusting portion 4 is relatively fixed. At this time, the other end of the adjusting portion 4 is extended toward the bow piece seat 1 and an adjusting scale 411 is provided on the extended end thereof, so that the adjusting portion 4 can subsequently move relative to the bow piece seat 1, and an indicating portion 5 corresponding to the adjusting scale 411 is also provided on the bow piece seat 1, that is, during adjustment, the bow piece seat 1 deflects relative to the bow handle 2, and the bow piece seat 1 can drive the indicating portion 5 to move, so that the indicating portion 5 can move relative to the adjusting scale 411 on the adjusting portion 4. Similarly, the adjustment status can be intuitively reflected through the front and rear changes of the indicating portion 5 relative to the adjusting scale 411, so that the user can adjust it to the right position at one time, avoiding the problem of repeated adjustment, improving the accuracy and efficiency of the adjustment, and also improving the efficiency of the use of the bow.
[0027] Figure 4 This is the structure of the adjustment part of a preferred embodiment of the utility model. Figure 1 , such as 3 and Figure 4As shown, an adjustment slot 412 is also provided on the adjustment portion 4 along its extension direction, so that the adjustment slot 412 can cover the length range of the adjustment portion 4, so that when the adjustment portion 4 moves relatively later, the adjustment slot 412 can also adapt to the movement stroke requirement. At this time, the adjustment scale 411 is arranged along the adjustment slot 412, so that the adjustment scale 411 can be arranged in the same direction as the adjustment slot 412, and the indicating part 5 also includes a bayonet 51, and when the adjustment part 4 and the indicating part 5 are installed in place, the bayonet 51 extends into the corresponding adjustment slot 412 of the adjustment part 4, so that when the adjustment slot 412 and the bayonet 51 subsequently have relative movement due to adjustment, the adjustment situation can be intuitively reflected through the change relationship between the bayonet 51 and the adjustment scale 411 in the same direction as the adjustment slot 412, thereby meeting the requirements of accurate and efficient adjustment. At the same time, the bayonet 51 can be moved in the adjustment slot 412 so that the bayonet 51 is restricted by the adjustment slot 412, ensuring that the bayonet 51 can only move in the adjustment slot 412, thereby limiting the adjustment stroke, thereby avoiding the problem of the bow body falling apart due to the loosening of the adjustment screw 3 after excessive adjustment, and effectively improving the safety protection effect.
[0028] More specifically, the adjustment part 4 includes an adjustment block 42 and an adjustment sheet 41. At this time, the adjustment block 42 is rotatably mounted on the adjustment screw 3, which can not only maintain the rotation of the adjustment screw 3, but also enable the adjustment block 42 to move axially with the adjustment screw 3 to meet the adjustment requirements. In addition, one end of the adjustment sheet 41 is fixedly mounted on the adjustment block 42, and the effective area of the side wall of the adjustment block 42 is expanded by the adjustment sheet 41, and the adjustment slot 412 is arranged on the adjustment sheet 41, so that the adjustment part 4 can better meet the change of the adjustment stroke and the arrangement requirements of the adjustment slot 412 with a certain length and the adjustment scale 411.
[0029] Figure 5 FIG. 1 is a structural diagram of the indicating part of a preferred embodiment of the utility model. Figure 1 , Figure 2 , Figure 3 as well as Figure 5As shown, the indicating part 5 includes not only the above-mentioned bayonet 51 but also a screw block 52. At this time, the screw block 52 is rotatably installed on the corresponding handle 2 or limb seat 1, so that the screw block 52 can rotate relatively, and the screw block 52 and the rotation axis of the limb seat 1 at the hinge point on the handle 2 are arranged in the same direction, and one end of the adjustment screw 3 is threadedly connected to the screw block 52, so that when the limb seat 1 deflects relative to the handle 2 and causes the adjustment screw 3 to swing, the screw block 52 can be adaptively rotated, thereby meeting the connection requirement that the adjustment screw 3 can always be connected to the screw block 52, and at the same time, the problem of the adjustment screw 3 being stuck can be avoided. In addition, the bayonet 51 is set on the screw block 52, so that the bayonet 51 can rotate with the screw block 52, thereby meeting the use requirement that the adjustment block 42 follows the movement of the adjustment screw 3, ensuring that the adjustment can be carried out normally. It is worth pointing out that the areas on the bow piece seat 1 and the bow handle 2 for the adjusting screw 3 to pass through are larger than the diameter of the adjusting screw 3. Preferably, the areas for the adjusting screw 3 to pass through can be designed as strip holes, so that when the adjusting screw 3 deflects due to adjustment, there is enough space for the adjusting screw 3 to deflect, thereby ensuring that adjustment can be achieved.
[0030] More specifically, the bayonet 51 is coaxially arranged with the rotation axis of the screw block 52, ensuring that when the screw block 52 rotates due to adjustment, the position of the bayonet 51 relative to the screw block 52 remains unchanged, and since the adjustment block 42 will also deflect as the installation angle between the bow piece seat 1 and the bow handle 2 changes relatively, the adjustment screw 3 will cause the adjustment part 4 provided with the adjustment slot 412 to swing, so that the deflection axis of the adjustment screw 3 when it swings is the same axis as the rotation axis of the screw block 52, thereby avoiding the problem of the bayonet 51 being stuck in the adjustment slot 412 and affecting the adjustment, thereby maintaining the effectiveness of the adjustment.
[0031] More specifically, the screw block 52 has an arc surface 521. Preferably, the screw block 52 is a cylinder, so that the outer wall of the screw block 52 is an arc surface 521, which can achieve non-directional installation, more convenient installation, and can adapt to a larger rotation angle, and has better adaptability. In addition, the corresponding bow piece seat 1 or the bow handle 2 is provided with a mounting hole 21 with a hole wall as an arc surface, and when the screw block 52 is installed in the mounting hole 21, the arc surface 521 of the screw block 52 and the arc surface of the mounting hole 21 are in contact, ensuring that the screw block 52 can rotate in the mounting hole 21, thereby meeting the adjustment requirements. It is worth pointing out that the hole wall of the mounting hole 21 with an arc surface is the hole wall close to the side of the adjusting screw 3, ensuring that the screw block 52 installed in the mounting hole 21 can be used in conjunction with the adjusting screw 3.
[0032] More specifically, the adjusting screw 3 is provided with a circle of annular grooves 31 along its circumference. At this time, a through hole 421 is provided on the adjusting block 42 of the adjusting portion 4. During installation, the adjusting screw 3 is passed through the adjusting block 42 of the adjusting portion 4 through the through hole 421, and is connected to the screw block 52 after the adjusting screw 3 passes through the adjusting block 42. At the same time, it is ensured that the adjusting block 42 can rotate relative to the adjusting screw 3, thereby ensuring that the adjusting screw 3 can be adjusted. In addition, a limit pin 43 is also provided on the adjustment block 42 of the adjustment part 4. During installation, the limit pin 43 is inserted into the adjustment block 42 of the adjustment part 4, and one side of the limit pin 43 is inserted into the through hole 421 and protrudes into the through hole 421, that is, a limiting structure is formed in the through hole 421 by the limit pin 43, and when the adjusting screw 3 passes through the adjustment block 42 of the adjustment part 4, the part of the limit pin 43 protruding into the through hole 421 is set to be inserted into the annular groove 31 on the adjusting screw 3, that is, the adjustment block 42 is limited to the annular groove 31 of the adjusting screw 3 by the part of the limit pin 43 protruding into the through hole 421, so that the adjustment part 4 can be axially fixed relative to the adjusting screw 3 and circumferentially rotate relative to the adjusting screw 3, which can not only ensure that the adjusting screw 3 can be turned, but also drive the adjustment part 4 to move, thereby meeting the use requirements of adjustment and visual adjustment conditions.
[0033] More specifically, an axial clearance eliminating spring 6 is further provided between the adjusting portion 4 and the corresponding bow piece seat 1 or the bow handle 2. At this time, the axial clearance eliminating spring 6 is sleeved outside the adjusting screw 3 to ensure the reliability of the installation of the axial clearance eliminating spring 6. At the same time, one end of the axial clearance eliminating spring 6 is pressed against the adjusting portion 4, and the other end of the axial clearance eliminating spring 6 is pressed against the corresponding bow piece seat 1 or the bow handle 2. The adjusting portion 4 is supported by the axial clearance eliminating spring 6 so that the adjusting portion 4 is restricted in the annular groove 31 by the limit pin 43. The axial clearance eliminating spring 6 can push the limit pin 43 to one side of the annular groove 31 by pushing the adjusting portion 4, thereby eliminating the assembly gap between the limit pin 43 and the annular groove 31, avoiding the problem of the adjusting portion 4 moving in the assembly gap under the action of its own gravity, and ensuring the adjustment accuracy.
[0034] More specifically, a lateral gap elimination component 7 is also provided on the adjusting portion 4 or the indicating portion 5. At this time, the lateral gap elimination component 7 includes a tightening spring and a top block. In addition, a telescopic hole 522 is opened on the adjusting portion 4 or the indicating portion 5 on which the lateral gap elimination component 7 is provided. During installation, the opening of the telescopic hole 522 is arranged toward the corresponding indicating portion 5 or the adjusting portion 4, that is, when the lateral gap elimination component 7 is provided on the adjusting portion 4, the telescopic hole 522 is provided on the adjusting portion 4, and the opening of the telescopic hole 522 is arranged toward the indicating portion 5; similarly, when the lateral gap elimination component 7 is provided on the indicating portion 5, the telescopic hole 522 is provided on the indicating portion 5, and the opening of the telescopic hole 522 is arranged toward the adjusting portion 4. At this time, a tightening spring is arranged in the telescopic hole 522, and a top block is arranged at the opening of the telescopic hole 522 to press the tightening spring, that is, the tightening spring provides a pre-tightening force for the top block, and at the same time, the side of the top block away from the tightening spring is extended out of the opening and presses against the corresponding indicating part 5 or adjusting part 4, that is, the top block presses against the indicating part 5 or adjusting part 4, thereby eliminating the assembly gap between the adjusting block 42 of the adjusting part 4 and the screw block 52 of the indicating part 5, avoiding the problem of tilting and swinging between the two during adjustment, maintaining the stability of the adjustment structure, and ensuring the accuracy of adjustment. Preferably, the top block is a spherical structure, which better adapts to the use requirements of the adjusting block 42 of the adjusting part 4 rotating relative to the screw block 52 of the indicating part 5.
[0035] More specifically, the adjusting piece 41 of the adjusting part 4 is provided with two pieces. At this time, the two adjusting pieces 41 are respectively arranged on both sides of the adjusting block 42, so that the adjusting part 4 can form a structure with a side shape of "U" as a whole, so that both sides of it have the ability of connection limit and adjustment visibility. During the subsequent installation, the two adjusting blocks 42 are respectively located on both sides of the corresponding bow piece seat 1 and / or bow handle 2. At the same time, two bayonet pins 51 are correspondingly arranged on the indicating part 5 and correspond to the two adjusting blocks 42 respectively, so that the adjusting part 4 and its installation are both a symmetrical structure, which not only improves the structural strength and the adjustment stability, but also enables both sides to have the above-mentioned connection limit and adjustment visibility capabilities, and assembly and use can be more convenient. Preferably, each adjusting piece 41 and the adjusting block 42 are connected and locked by screws, so that the installation of the adjusting block 42 and the adjusting piece 41 is realized, the structure is flexible, and the disassembly and assembly are convenient, which is conducive to assembly and later maintenance and repair.
[0036] More specifically, the adjustment scale 411 on the adjustment part 4 includes but is not limited to length scale, kilogram scale, pound scale and other commonly used scales that can reflect the magnitude of force, which can meet the user's usage habits and will not be repeated here.
