Description

Technical Field

[0001] The invention relates to the technical field of bite force testing, and in particular to a dog bite force testing device with an adjustment function. Background Art

[0002] With the popularity of pet dogs, understanding and evaluating the bite force of dogs is of great significance for pet health monitoring, training and research. Traditional dog bite force testing devices usually include a fixed bite force sensing unit, which is designed to be placed in a specific position for dogs to bite. However, this fixed design has significant shortcomings: due to the large individual differences among dogs, when dogs of different sizes use bite force sensing units set at the same height, it is difficult to ensure that the direction of the force generated when they bite naturally is completely perpendicular to the direction of the sensing unit. When the bite force direction is not perpendicular to the sensing unit, the actual measured bite force will be less than the actual force exerted by the dog, thereby affecting the accuracy of the test results. In addition, the traditional device lacks flexibility and cannot adjust the bite angle according to the different body shapes of dogs, which further limits its scope of application and accuracy.

[0003] In order to solve the above problems, we propose a dog bite force testing device with adjustment function. This bite force testing device can adapt to dogs of various sizes and can automatically adjust during the biting process to ensure that the bite force direction remains perpendicular to the sensing unit, thereby improving the test accuracy.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: A dog bite force testing device with an adjustable function, such as Figure 1-Figure 7As shown, it includes a mounting plate 1, a sliding plate 2, a slider 3, a turntable 4, a fixed block 5, an adjusting rod 6, a rotating seat 7, a volute spring 71, a mounting rod 8, a rotating block 9, a torsion spring 10, a bite force sensor 11, a fixed component and a telescopic component. The middle part of the mounting plate 1 is slidably connected with two sliding plates 2 symmetrical on the left and right. The rear of the sliding plate 2 is slidably connected with a slider 3. The slider 3 is rotatably connected with a turntable 4. A protrusion is provided at the rotation connection between the turntable 4 and the slider 3. A limiting groove is opened on the side of the slider 3 close to the turntable 4. The limiting groove cooperates with the protrusion to limit the rotation direction of the turntable 4. A fixed block 5 is fixedly connected between the left and right turntables 4. The sliding plate 2 is rotatably connected to the rear of the cage, and the adjusting rod 6 is connected to the slider 3 by threads. The middle of the fixed block 5 is rotatably connected to the rotating seat 7, and a spiral spring 71 is connected between the rotating seat 7 and the fixed block 5. A mounting rod 8 is inserted at the rear side of the rotating seat 7, and a rotating block 9 is rotatably connected to the rear of the mounting rod 8. Two torsion springs 10 are connected between the rotating block 9 and the mounting rod 8, and a bite force sensor 11 is installed on the rotating block 9. A fixing component for clamping the cage for fixing is provided on the mounting plate 1, and a telescopic component is provided on the mounting plate 1 and the sliding plate 2. The telescopic component is used to control the sliding plate 2 to slide forward and backward to adjust the position of the bite force sensor 11.

[0031] When using the device, the staff fixes the device on the cage through the fixing component, and then controls the sliding plate 2 to slide forward or backward for extension and contraction through the telescopic component, thereby adjusting the position of the bite force sensor 11 extending into the cage, and the adjusting rod 6 rotates to drive the slider 3 to slide up and down, and can also adjust the height of the bite force sensor 11 to adapt to dogs of different sizes. Under the action of the limit groove and the protrusion, the rotation direction of the turntable 4 can be limited, so that the installation rod 8 cannot swing downward, so as to maintain a horizontal state to facilitate the dog to bite the bite force sensor 11 for testing. Then the dog bites the bite force sensor 11 (the bite force sensor 11 can be coated with bait to lure the dog to bite the bite force sensor 11), and the bite force sensor 11 is tested. The dog's bite force. During the test, if the dog bites the bite force sensor 11 from the back to the front facing the rear side of the device, the rotating block 9 can swing up and down on the mounting rod 8 under the action of the torsion spring 10, thereby driving the bite force sensor 11 to swing up and down to adjust the angle to adapt to the dog's bite direction. If the dog faces the left or right side of the device and bites the bite force sensor 11 from the side, the rotating seat 7 can also rotate on the fixed block 5 under the action of the spiral spring 71, thereby driving the mounting rod 8, the rotating block 9 and the bite force sensor 11 to rotate and adjust the angle. Through the adaptive adjustment of the lateral and longitudinal angles, it can adapt to the dog's bite direction, ensure that the bite force direction is perpendicular to the bite force sensor 11, and improve the test accuracy.

[0032] like Figure 1 , Figure 2 and Figure 6As shown, the fixing assembly includes a fixed clamping plate 12, a slide plate 13, a movable clamping plate 14, a guide rod 15, an extrusion frame 16 and a threaded rod 17. The left and right parts of the mounting plate 1 are fixedly connected to the fixed clamping plate 12, the left and right parts of the mounting plate 1 are slidably connected to the slide plate 13, the outer side of the slide plate 13 is fixedly connected to the movable clamping plate 14, the right part of the mounting plate 1 is fixedly connected to the guide rod 15, the guide rod 15 is slidably connected to the extrusion frame 16, the left and right parts of the extrusion frame 16 are upwardly inclined bending structures, the slide plate 13 is provided with a convex rod, the extrusion frame 16 moves upward to be extruded and matched with the convex rod, the left part of the mounting plate 1 is rotatably connected to the threaded rod 17, and the threaded rod 17 is connected to the extrusion frame 16 by threads.

[0033] When using the device, the staff extends the rear part of the device into the cage so that the cage rod is located between the left and right sets of fixed clamps 12 and the movable clamp 14, and then the staff controls the threaded rod 17 to rotate, the rotation of the threaded rod 17 drives the extrusion frame 16 to slide upward, the extrusion frame 16 slides upward to extrude the protruding rod, and then drives the slide plate 13 to slide inward, the inward sliding of the slide plate 13 drives the movable clamp 14 to move inward, the movable clamp 14 moves inward and cooperates with the fixed clamp 12 to clamp the cage rod, and then fixes the device on the cage for bite force testing.

[0034] like Figure 1 and Figure 7 As shown, the telescopic assembly includes a matching rod 18, a fixed plate 19 and a space cam 20. The front part of the sliding plate 2 on the left is fixedly connected to the matching rod 18, the middle part of the mounting plate 1 is fixedly connected to the fixed plate 19, the fixed plate 19 is rotatably connected to the space cam 20, and the matching rod 18 is slidably connected to the space cam 20.

[0035] When using the device, the staff controls the rotation of the space cam 20, and the rotation of the space cam 20 drives the matching rod 18 to move forward or backward. The forward or backward movement of the matching rod 18 will drive the sliding plate 2 to slide forward and backward, thereby driving the bite force sensor 11 to move forward and backward to adjust the distance extended into the cage. When the device is used, the staff controls the sliding plate 2 to slide forward through the space cam 20 and the matching rod 18, thereby driving the installation rod 8 and the bite force sensor 11 and other components to retract forward, thereby reducing the area occupied by the internal area of ​​the cage.

[0036] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 8As shown, it also includes a folding component for controlling the mounting rod 8 to fold upward, the folding component includes a contact block 21, a push rod 22, a first extrusion block 23, a locking rod 24 and a first spring 25. The contact block 21 is fixedly connected to the lower front part of the turntable 4, and two left and right symmetrical push rods 22 are fixedly connected to the middle part of the lower side of the mounting plate 1. The contact block 21 moves forward and is pressed and matched with the push rod 22. The left and right parts of the rear side of the mounting plate 1 are fixedly connected to the first extrusion block 23, and the rear part of the sliding plate 2 is slidably connected to the locking rod 24. One end of the locking rod 24 is inserted into the turntable 4. The rear part of the first extrusion block 23 is wedge-shaped, and the other end of the locking rod 24 is pressed and matched with the first extrusion block 23. A first spring 25 is connected between the locking rod 24 and the sliding plate 2.

[0037] In the initial state, the locking rod 24 is locked in the turntable 4, thereby fixing the turntable 4 so that the mounting rod 8 remains in a horizontal state, preventing the mounting rod 8 from swinging up and down and affecting the dog biting the bite force sensor 11 for testing. When the device is used, the sliding plate 2 slides forward to drive the turntable 4 to move forward, and the locking rod 24 and the contact block 21 move forward accordingly. When the locking rod 24 moves forward to contact with the first extrusion block 23, the locking rod 24 continues to move forward and will be squeezed by the first extrusion block 23 to slide outward, and the first spring 25 is deformed. After sliding outward, the locking rod 24 no longer blocks the turntable 4, and when the contact block 21 moves forward to contact with the push rod 22, the contact block 21 will be squeezed by the push rod 22 to rotate backward, and the squeezing and backward rotation drives the turntable 4 to rotate clockwise, and the clockwise rotation of the turntable 4 drives the fixed The block 5 rotates, and the fixed block 5 rotates to drive the rotating seat 7, the mounting rod 8, the rotating block 9 and the bite force sensor 11 to rotate and fold upward, further reducing the occupation of the internal area of ​​the cage. When the device needs to be used again, the staff controls the sliding plate 2 to slide backward, and the sliding plate 2 slides backward to make the turntable 4, the positioning rod 24 and the contact block 21 and other components move backward. After the contact block 21 moves backward, it is no longer squeezed by the top rod 22. At this time, under the action of gravity, the rotating seat 7, the mounting rod 8, the rotating block 9 and the bite force sensor 11 rotate downward and open, and the fixed block 5 and the turntable 4 rotate counterclockwise to reset. When the positioning rod 24 moves backward and is no longer squeezed by the first squeezing block 23, under the action of the reset of the first spring 25, the positioning rod 24 slides inward and is re-engaged in the turntable 4.

[0038] like Figure 1 , Fig. 9 and Fig.10As shown, it also includes a locking assembly for locking the mounting rod 8, the locking assembly includes a clamping rod 26, a sliding rod 27, a second spring 28, a second extrusion block 29 and a fixing frame 30, the rotating seat 7 is slidably connected with a clamping rod 26 symmetrical in upper and lower directions, the rear end of the clamping rod 26 is inserted into the mounting rod 8, the center position of the rotating seat 7 is slidably connected with a sliding rod 27, a second spring 28 is connected between the sliding rod 27 and the rotating seat 7, a second extrusion block 29 is fixedly connected to the front side of the sliding rod 27, a fixing frame 30 is fixedly connected between the rear parts of the left and right sliding plates 2, the second extrusion block 29 is an elliptical disk structure with a thick middle and thin edges, the second extrusion block 29 is slidably connected to the front end of the clamping rod 26, and the second extrusion block 29 is rotated downward to be extruded and matched with the fixing frame 30.

[0039] When the second extrusion block 29 is rotated downward to contact with the fixing frame 30, the second extrusion block 29 will be squeezed by the fixing frame 30 to move toward the direction close to the fixing frame 7, and the sliding rod 27 will slide toward the fixing frame 7 accordingly. The second spring 28 will be deformed, and when the second extrusion block 29 moves close to the fixing frame 7, it will squeeze the card rod 26 to slide backward. After the card rod 26 slides backward, the installation rod 8 is unlocked. At this time, the installation rod 8 and the fixing frame 30 are locked. The movable block 9 and the bite force sensor 11 have been rotated and folded upward, and the staff can directly remove the mounting rod 8, the rotating block 9 and the bite force sensor 11 from the rotating seat 7, so as to clean the residual attractant on the bite force sensor 11 or add new attractant. When the device needs to be reused, the turntable 4 rotates counterclockwise to reset and drives the entire locking assembly to rotate upward. After the second extrusion block 29 rotates upward, it is no longer squeezed by the fixed frame 30. At this time, under the action of the second spring 28 resetting, the sliding rod 27 drives the second extrusion block 29 to move away from the rotating seat 7, and then the extrusion clamping rod 26 slides toward each other and re-inserts into the mounting rod 8 for locking.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application.
