Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of bow and arrow accessories, especially relates to a 360 degree pound measuring release. BACKGROUND

[0002] The bow and arrow release is an indispensable accessory for the compound bow. The bow and arrow release is mainly used for string drawing, which can avoid the direct contact between the fingers and the bowstring, avoid the blistering and abrasion of the fingers, and play a protective and auxiliary role. The compound bow has greater power than the traditional bow and arrow, and especially when the novice player uses it, the compound bow with appropriate poundage must be selected to effectively improve the use experience and ensure the safety of the player. There are pound measuring devices on the market for measuring the poundage, but the pound measuring devices are generally too large to be inconvenient to carry, and the measurement operation is relatively complicated, which is inconvenient for the novice player to use at any time.

[0003] Therefore, a bow and arrow release for measuring poundage with the application number "202421330560.9" and the name "a bow and arrow release for measuring poundage" is developed to solve the above technical problems. The patent discloses a bow and arrow release for measuring poundage, which includes a control cavity shell, a first opening and a second opening are arranged on the two sides of the control cavity, a jaw block is rotatably connected in the first opening, a hooking part is arranged on the jaw block, a force sensor is rotatably connected in the control cavity, a second reset spring is arranged between one end of the force sensor and the control cavity, a control block is rotatably connected in the second opening, the control block is used for directly or indirectly applying a pressing force to the force sensor, a display module is arranged on the shell, and the display module is signal connected with the force sensor. When the product is used, the bowstring is tensioned to generate a pulling force on the jaw block. The pulling force is transmitted to the force sensor and converted into a millivolt signal output. The display module receives the millivolt signal, converts it into poundage information, and displays it. The function of measuring the poundage is integrated into the bow and arrow release, the operation of measuring the poundage is simplified, and the user can use and carry it at any time.

[0004] However, the above-mentioned patent product has the following defects in actual use. 1. Because of the structure, the force received by the sensor is bending stress. When the direction of the pulling force changes, the sensor signal also changes, and finally the pulling force displayed on the display screen fluctuates greatly, thereby affecting the final measurement result. 2. The clamping part with the jaw block cannot rotate 360 degrees relative to the shell, which is inconvenient to use. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a 360 degree pound measuring release to solve the technical problems that the sensor signal is unstable when the pulling force direction and the pulling force contact point of the existing bow and arrow release change, resulting in large fluctuation of the final measurement data, and the clamping part cannot rotate 360 degrees relative to the shell.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a 360° weighing spreader, comprising a housing, a force sensor fixedly installed in the housing, and a clamping part rotatably connected to the housing. The clamping part has an openable and closable jaw block. The housing is provided with a transmission component for controlling the opening and closing of the jaw block. A connecting component for applying pressure to the force sensor is provided between the clamping part and the force sensor. The housing is also provided with a display module, and the display module is signal-connected to the force sensor.

[0007] Furthermore, the connecting assembly includes a sleeve with a through hole, one end of the sleeve having a stepped outer ring with a diameter larger than that of the sleeve, the end of the sleeve away from the stepped outer ring being fixedly connected to the clamping part, the force sensor having a connecting hole matching the diameter of the sleeve, one end of the sleeve passing through the connecting hole so that the stepped outer ring and the force sensor abut against each other.

[0008] Furthermore, the housing has a receiving groove for installing a force sensor, and the receiving groove has a through groove and an opening on both sides, with the sleeve rotatably disposed in the through groove.

[0009] Furthermore, the transmission assembly includes a control block and a push rod. The control block is rotatably disposed at the opening. One end of the push rod abuts against the control block, and the other end extends through the sleeve into the clamping part.

[0010] Furthermore, the clamping part has a movable groove, and the upper and lower ends of the movable groove are hinged with jaw blocks. A spring is provided between the jaw blocks. Guide grooves are provided on the inner walls of both sides of the clamping part. A steel ball is movably arranged between the guide grooves on both sides. One end of the push rod abuts against the steel ball, and the opening and closing of the jaw blocks is controlled by pushing the steel ball.

[0011] Furthermore, a connecting groove is provided on the outer wall of one end of the sleeve, and the end with the connecting groove extends into the clamping part. The clamping part is provided with a mounting hole corresponding to the connecting groove, and a connecting post is provided in the mounting hole. The connecting post is engaged in the connecting groove to fix the sleeve and the clamping part together.

[0012] Furthermore, a trigger is rotatably connected to the control block, the control block is provided with an arc-shaped positioning groove, the trigger is provided with a positioning hole, and a positioning bolt that penetrates the arc-shaped positioning groove is provided in the positioning hole.

[0013] Furthermore, the display module includes a power supply, a PCB board, and a display screen that are electrically connected to each other. The power supply and the PCB board are disposed inside the housing. The housing has a clearance opening, and the display screen is fixed in the clearance opening.

[0014] Furthermore, a battery compartment for storing power is provided on the side of the housing away from the clearance opening, and the battery compartment is provided with a cover for opening or closing the battery compartment.

[0015] Through the above technical solution, compared with the prior art, this utility model has the following beneficial effects: 1. By fixing a force sensor inside the housing and setting a clamping part at one end of the housing, the clamping part has an openable and closable jaw block. A connecting component is provided between the clamping part and the force sensor. At the same time, a transmission component for controlling the opening and closing of the jaw block is also provided inside the housing. When in use, the bowstring is clamped by the jaw block. When the bowstring is tensioned, it will generate a pulling force on the jaw block. Since the jaw block and the clamping part are fixed together, and the clamping part is connected to the force sensor through the connecting component, the generated pulling force is further transmitted to the connecting component and pressure is applied to the force sensor through the connecting component. The force sensor then converts it into a millivolt signal output. Finally, the display module receives the millivolt signal and converts it into a weight information and displays it.

[0016] 2. By providing a rotatable clamping part on one side of the housing, the clamping part with the jaw block can rotate 360° relative to the housing, making this dispenser more convenient to use.

[0017] By employing the above method, the jaw block can rotate 360° freely, and the sensor signal remains relatively stable even when the direction of the pulling force and the point of contact with the pulling force change, thus not affecting the final measurement results. This solves the technical problems of existing arrow releasers where the sensor signal is unstable when the direction of the pulling force and the point of contact with the pulling force changes, leading to large fluctuations in the final measurement data, and the clamping part cannot rotate 360° relative to the housing.

[0029] The following will refer to the appendix in the embodiments of this utility model. Figures 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

[0031] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0032] like Figures 1-6 The first embodiment of this utility model is shown: a 360° weighing spreader, including a housing 1, a force sensor 2 fixedly installed in the housing 1, and a clamping part 3 rotatably connected to the housing 1. The clamping part 3 has an openable and closable jaw block 4. The housing 1 is provided with a transmission component for controlling the opening and closing of the jaw block 4. A connecting component for applying pressure to the force sensor 2 is provided between the clamping part 3 and the force sensor 2. The housing 1 is also provided with a display module 5, and the display module 5 is signal connected to the force sensor 2. In this embodiment, the housing 1 is assembled from an upper housing and a lower housing. A finger groove for easy gripping is formed on one side of the housing 1. When not in use, the jaw blocks 4 are in a closed state, and a closed inner groove is formed between the upper and lower jaw blocks 4. When in use, by applying pressure to the transmission component, the transmission component moves forward, thereby opening the jaw blocks 4. Then, the bowstring is placed between the two jaw blocks 4. At this time, since a spring 9 is provided between the jaw blocks 4 and the transmission component in this embodiment, when the transmission component moves forward to open the jaw blocks 4, it will apply pressure to the spring to store energy. When this applied force disappears, the spring 9 will release, thereby pushing the transmission component back, and the two jaw blocks 4 will close again, thereby clamping the bowstring in the closed inner groove. Then, the bowstring is pulled to make the bowstring taut. During this process, the bowstring applies pressure to the force sensor 2 through the relationship between the clamping part 3 and the connecting component, thereby generating tension. The tension is converted into millivolt information by the force sensor 2 and transmitted to the display module 5 for display, so that the user can view the weight.

[0033] like Figures 2-5As shown: The connecting assembly includes a sleeve 6 with a through hole. One end of the sleeve 6 has a stepped outer ring 601 with a diameter larger than that of the sleeve 6. The end of the sleeve 6 away from the stepped outer ring 601 is fixedly connected to the clamping part 3. The force sensor 2 has a connecting hole 201 that matches the diameter of the sleeve 6. One end of the sleeve 6 passes through the connecting hole 201 so that the stepped outer ring 601 and the force sensor 2 abut against each other. In this embodiment, the connecting assembly is a sleeve 6 with a stepped outer ring 601 at one end. Specifically, one end of the sleeve 6 passes through the force sensor 2. The connection hole 201 on sensor 2 causes the stepped outer ring 601 at its other end to abut against the force sensor, fixing the clamping part 3 and the sleeve 6 in place. Since the jaw block 4 is fixed on the clamping part 3, when the string is pulled, the bowstring inside the jaw block 4 will apply a force to the clamping part 3, which will then be transmitted to the stepped outer ring 601 of the sleeve 6, forcing it to apply pressure to the force sensor 2. Finally, the force sensor 2 converts the force into a millivolt signal output, which is received by the display module 5 and converted into a weight information and displayed.

[0034] like Figures 2-5 As shown: The housing 1 has a receiving groove 101 for installing the force sensor 2. The receiving groove 101 has positioning grooves on both sides that match the shape and size of the force sensor 2. The two ends of the force sensor 2 are fixed in the positioning grooves. The receiving groove 101 has a through groove 102 and an opening 103 on both sides. The sleeve 6 is rotatably disposed in the through groove 102. In this embodiment, the force sensor 2 is fixed by opening the receiving groove 101 in the housing 1. This method allows the force sensor 2 to be installed more stably in the housing 1, so that the force sensor will not shake during the string pulling process, reducing the measurement error.

[0035] In addition, the through groove 102 connects the receiving groove 101 to the outside. The sleeve 6 is rotatably disposed in the through groove 102. When the clamping part 3 rotates, it will drive the sleeve 6 to make corresponding movements.

[0036] like Figures 2-6 As shown: The transmission assembly includes a control block 7 and a push rod 8. The control block 7 is rotatably mounted at the opening 103. One end of the push rod 8 abuts against the control block 7, and the other end extends through the sleeve 6 into the clamping part 3. Figures 1-2As shown: The clamping part 3 has a movable groove 301. The upper and lower ends of the movable groove 301 are hinged with jaw blocks 4. A spring 9 is provided between the jaw blocks 4. The inner walls on both sides of the clamping part 3 are provided with guide grooves 302. A steel ball 10 is movably arranged between the two guide grooves 302. One end of the push rod 8 abuts against the steel ball 10. The opening and closing of the jaw blocks 4 is controlled by pushing the steel ball 10. In this embodiment, the push rod 8 is moved forward by pressing down the push block 7 to push the steel ball 10. Since a space for the steel ball 10 to move is formed between the upper and lower jaw blocks 4 and the space on the side of the push rod 8 gradually narrows inward, when the steel ball 10 moves from the larger space to the smaller space, its upper and lower ends gradually abut against the two jaw blocks 4, and then pushes the upper and lower jaw blocks to realize the opening and closing of the jaw blocks.

[0037] By setting the guide groove 302, the steel ball 10 can be guided and limited. The push rod 8 is movably set in the sleeve 6 through the through hole on the sleeve 6.

[0038] like Figure 2 As shown: In this embodiment, a connecting groove 602 is provided on the outer wall of one end of the sleeve 6. The end with the connecting groove 602 extends into the clamping part 3. The clamping part 3 is provided with a mounting hole corresponding to the connecting groove 602. A connecting post 11 is provided in the mounting hole. The connecting post 11 is locked in the connecting groove 602 to fix the sleeve 6 and the clamping part 3 together.

[0039] like Figures 1-6 As shown: A trigger 12 is rotatably connected to the control block 7. The control block 7 is provided with an arc-shaped positioning groove 701. The trigger 12 is provided with a positioning hole. A positioning bolt that passes through the arc-shaped positioning groove is provided in the positioning hole. The trigger 12 can rotate along the arc-shaped positioning groove 701 to meet the usage habits of different users.

[0040] like Figures 1-2 As shown: The display module includes a power supply, a PCB board, and a display screen that are electrically connected to each other. The power supply and PCB board are located inside the housing 1. The housing 1 has a clearance opening, and the display screen is fixed in the clearance opening to display the specific weight. The display module 5 also includes a switch button. The housing 1 has a button hole, and the switch button is located in the button hole. The switch button is used to control the power on and off of the display module 5.

[0041] The housing 1 has a battery compartment for storing power on the side away from the clearance opening. The battery compartment is provided with a cover for opening or closing the battery compartment. The battery compartment and the cover are provided to facilitate the replacement of the battery inside.

[0042] like Figure 7The second embodiment of this utility model is shown below. The difference between this embodiment and the first embodiment is that in this embodiment, the transmission component includes a control block 7 and a ball-head push rod 13. The end of the ball-head push rod 13 away from the ball head abuts against the control block 7 and extends to the inside of the control block 7. The end with the ball head passes through the sleeve 6 and abuts against the spring 9 disposed between the upper and lower jaw blocks 4. In use, by pressing the control block 7, the control block 7 pushes the ball-head push rod 13 forward and compresses the spring 9 to open the jaw blocks 4. Compared with the first embodiment, this embodiment saves the steel ball 10 component, thereby reducing the overall manufacturing cost.

[0043] In summary, the principle and beneficial effects of this utility model are as follows:

[0044] A force sensor 2 is fixedly installed inside the housing 1, and a clamping part 3 is provided at one end of the housing 1. The clamping part 3 has an openable and closable jaw block 4. A connecting component is provided between the clamping part 3 and the force sensor 2. At the same time, a transmission component for controlling the opening and closing of the jaw block 4 is also provided inside the housing 1. In use, the bowstring is clamped by the jaw block 4. When the bowstring is tensioned, it will generate a pulling force on the jaw block 4. Since the jaw block 4 and the clamping part 3 are fixed together, and the clamping part 3 is connected to the force sensor 2 through the connecting component, the generated pulling force is further transmitted to the connecting component and pressure is applied to the force sensor 2 through the connecting component. The force sensor 2 then converts it into a millivolt signal output. Finally, the display module receives the millivolt signal, converts it into a weight information and displays it.

[0045] By providing a rotatable clamping part 3 on one side of the housing 1, the clamping part 3 with the jaw block 4 can rotate 360° relative to the housing 1, thereby making the dispenser more convenient to use.

[0046] By means of the above method, the jaw block 4 can rotate 360° arbitrarily, and the sensor signal remains relatively stable when the direction of the pulling force and the point of contact with the pulling force change, so as not to affect the final measurement results. This solves the technical problems of the existing arrow release device, such as the unstable sensor signal when the direction of the pulling force and the point of contact with the pulling force change, which leads to large fluctuations in the final measurement data, and the inability of the clamping part to rotate 360° relative to the shell.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
