Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry tools, more specifically to a discharge telescopic mechanism and an animal driving device. Background Art

[0002] Existing livestock farms are mostly large-scale operations, such as pig farms. Moving animals to designated locations is a complex task for these uninitiated animals. Traditional methods of moving animals, typically by hitting them with a stick, are not only inefficient but also prone to causing harm.

[0003] Therefore, some have invented a method for driving animals away using high voltage and low current, which harms them and improves driving efficiency. Chinese Patent Publication No. CN215602575U discloses a motor-driven pig chaser, comprising: a handle that acts on a control device; a connector mounted on one side of the handle, made of an insulating material; an electric shock contact connected to the connector, which is responsive to the radiated current; and a wire connecting the electric shock contact and the connector; a sleeve fixedly connected to the handle and serving as a carrier; and a connecting rod embedded in the sleeve, with a sliding connection between the connecting rod and the sleeve, and a threaded groove formed inside the connecting rod. This electric pig chaser uses a first threaded rod to drive the connecting rod to slide along the sleeve, thereby adjusting the length of the connecting rod. A second threaded rod drives the connecting block to move, which drives the electric shock contact to slide into the connecting groove for easy storage. A hand strap is provided to secure the operator's hand when holding the handle, preventing it from falling off.

[0004] In the above patent, a first threaded rod is used to drive the connecting rod to slide along the inside of the sleeve, so that the length of the connecting rod can be adjusted. The structure is relatively complex and the production cost is high. Moreover, the connecting rod is embedded in the sleeve, and the connection between the electric shock contact wires and the handle is prone to cause the wires to be entangled when the length of the connecting rod is adjusted, resulting in an unsmooth extension or retraction.

[0033] Figures 1 to 7 It is the accompanying drawing of the present utility model.

[0034] This embodiment provides a discharge telescopic mechanism, see Figure 1 、 2 , includes an electrode head 11, a fixed rod 12, a telescopic rod group 13 arranged between the fixed rod 12 and the electrode head 11, and a cable 14 with one end connected to the electrode head 11 and the other end located on the fixed rod 12. The fixed rod 12 and the telescopic rod group 13 are both hollow structures, and the cable 14 runs through the hollow structure. The hollow structure of the fixed rod 12 and the telescopic rod group 13 can be used to pass the cable 14, so that the cable 14 is located inside, which is more convenient to operate and has a simpler structure. When the telescopic rod group 13 is telescopic, it prevents the cable 14 from getting tangled and messy. The telescopic rod group 13 moves axially relative to the fixed rod 12 to adjust the distance between the electrode head 11 and the fixed rod 12. The electrode head 11 is fixedly set at the end of the telescopic rod group 13. The telescopic rod group 13 can move telescopically, so that the electrode head 11 can extend or retract relative to the fixed rod 12, thereby adjusting the distance between the electrode head 11 and the fixed rod 12. The electrode head 11 is electrically connected to the cable 14 to provide power to the electrode head 11. The fixed rod 12 is used to fix to the main unit or other related components, and is slidably connected to the telescopic rod assembly 13. Specifically, one end of the telescopic rod assembly 13 is inserted into the hollow structure of the fixed rod 12, so that the end of the telescopic rod assembly 13 extending into the hollow structure of the fixed rod 12 can slide axially relative to the fixed rod 12, thereby extending or retracting the telescopic rod assembly 13 relative to the fixed rod 12.

[0035] See also Figure 1 、 2The telescopic rod group 13 includes a first movable rod 131 and a first positioner 132. One end of the first movable rod 131 is fixedly connected to the electrode head 11, and the other end is movably connected to the hollow structure of the fixed rod 12. The outer diameter of the first movable rod 131 is approximately the same size as or slightly smaller than the inner diameter of the fixed rod 12, so that the first movable rod 131 can slide in the hollow structure of the fixed rod 12. The first positioner 132 is arranged at one end of the fixed rod 12 close to the first movable rod 131, so that the first movable rod 131 can extend or retract relative to one end of the fixed rod 12, and the first positioner 132 can be locked after moving a set distance. The relative position between the first movable rod 131 and the fixed rod 12 is locked by the first positioner 132, which is convenient for operation, has a simple structure, and the length of extension or retraction is controllable.

[0036] For details, please refer to Figure 2 , an external thread is provided on the outer side of the end of the fixed rod 12 near the first movable rod 131, and the internal thread provided on the first locator 132 itself is connected to the external thread of the fixed rod 12. Rotating the first locator 132 causes the first movable rod 131 and the first locator 132 to squeeze each other, so that the movement between the first movable rod 131 and the fixed rod 12 is fixed in relative position. The first locator 132 is a cylindrical structure, with an internal thread provided at one end and a through hole 1321 for passing through the first movable rod 131 at the other end. The diameter of the through hole 1321 is slightly larger than the diameter of the first movable rod 131, so that the first movable rod 131 can extend or retract through the first locator 132. Among them, a wedge-shaped cylinder 1322 is provided inside the end of the first locator 132 near the through hole 1321. The wedge-shaped barrel 1322 is sleeved within the first locator 132. When the first locator 132 rotates along the thread, the wedge-shaped barrel 1322 squeezes into the gap between the first movable rod 131 and the fixed rod 12, so that the first movable rod 131 is fixed to the fixed rod 12 under the action of the first locator 132. More specifically, the outer diameter of one end of the wedge-shaped barrel 1322 is larger than the outer diameter of the other end, and the two ends have a straight surface transition or an arcuate surface transition, so that the outer side surface of the wedge-shaped barrel 1322 is inclined. Therefore, the end of the wedge-shaped barrel 1322 with a smaller outer diameter gradually approaches the gap between the first movable rod 131 and the fixed rod 12, thereby fixing the first movable rod 131 and the fixed rod 12 to each other. The wedge-shaped barrel 1322 is fixedly connected to the first locator 132. When the first locator 132 rotates, the wedge-shaped barrel 1322 can also move with it.

[0037] Preferably, see Figure 2The inner diameter of the wedge-shaped cylinder 1322 is equal to the outer diameter of the first movable rod 131, and the wedge-shaped cylinder 1322 squeezes the gap between the first movable rod 131 and the fixed rod 12. Therefore, the wedge-shaped cylinder 1322 has a sealing effect on the hollow structure between the first movable rod 131 and the fixed rod 12, so that the first positioner 132 has a waterproof effect when connecting the first movable rod 131 and the fixed rod 12.

[0038] Preferably, see Figure 2 A fixing cylinder 121 is provided at one end of the fixing rod 12 close to the first movable rod 131. The fixing cylinder 121 is fixedly connected to the fixing rod 12. An external thread that is threadedly connected to the first locator 132 is provided on the outside of the fixing cylinder 121. One end of the fixing cylinder 121 is fixedly connected to the fixing rod 12, and the other end extends beyond one end of the fixing rod 12. A gap is formed between the outside of the first movable rod 131 and the inside of the fixing cylinder 121. The gap is open to one side of the first movable rod 131. Therefore, when the first locator 132 rotates and moves toward the fixing rod 12 along the thread, one end of the wedge-shaped cylinder 1322 can be inserted into the gap, so that the first movable rod 131 and the fixing rod 12 can be squeezed against each other, and the two are fixed by friction. The first positioner 132 is loosened along the thread, and the first movable rod 131 can be extended or retracted to a selected distance relative to the fixed rod 12. After reaching the selected position, the first positioner 132 is tightened along the thread toward the fixed rod 12, which can fix the first movable rod 131 and the fixed rod 12 to each other, thereby achieving the purpose of adjusting the length of this mechanism.

[0039] In other embodiments, see Figure 3 The first locator 132 is provided with a spring pin 1323, and a positioning hole 1324 matching the spring pin 1323 is provided on the first movable rod 131 or the fixed rod 12. When the first locator 132 is fixed to the fixed rod 12, the first movable rod 131 is provided with multiple positioning holes 1324 in the axial direction. After the first movable rod 131 is extended or retracted to a set distance, the spring pin 1323 is inserted into the positioning hole 1324 of the first movable rod 131; or when the first locator 132 is fixed to the first movable rod 131, the fixed rod 12 is provided with multiple positioning holes 1324 in the axial direction. After the first movable rod 131 is extended or retracted to a set distance, the spring pin 1323 is inserted into the positioning hole 1324 of the fixed rod 12, thereby achieving the purpose of adjusting the length.

[0040] In other embodiments, see Figure 1 、 4In order to be able to adjust the length over a wider range, the telescopic rod group 13 also includes a second movable rod 133 and a second positioner 134. The second movable rod 133 is a hollow structure. One end of the second movable rod 133 is fixedly connected to the electrode head 11, and the other end is movably connected to the hollow structure of the first movable rod 131. The outer diameter of the second movable rod 133 is approximately the same size as or slightly smaller than the inner diameter of the first movable rod 131, so that the second movable rod 133 can slide within the hollow structure of the first movable rod 131. The second positioner 134 is arranged at one end of the first movable rod 131 close to the second movable rod 133, so that the second positioner 134 fixes the relative position between the second movable rod 133 and the first movable rod 131. The function of the second positioner 134 is the same as that of the first positioner 132, and its purpose is to fix the second movable rod 133 and the first movable rod 131 to each other after the second movable rod 133 is extended or retracted a certain distance. Since the second positioner 134 functions similarly to the first positioner 132, their structures are identical, and their detailed structures are not repeated here. The second positioner 134 is disposed at an end of the first movable rod 131 near the second movable rod 133. Rotating the second positioner 134 loosens or locks the relative position of the second movable rod 133 to the first movable rod 131, thereby adjusting the distance that the first movable rod 131 extends or retracts relative to the second movable rod 133, thereby adjusting the length of the adjustment mechanism.

[0041] In other embodiments, in addition to the above-mentioned first movable rod 131 and second movable rod 133, in order to be able to adjust the longer telescopic length, the telescopic rod group 13 also includes a third movable rod and a third positioner. The second movable rod 133 is a hollow structure, one end of the third movable rod is inserted into the hollow structure of the second movable rod 133, and the other end is fixedly connected to the electrode head 11. The outer diameter of the third movable rod is equal to or slightly smaller than the inner diameter of the second movable rod 133, so that the third movable rod can extend or retract along the hollow structure of the second movable rod 133. The third positioner has the same structure as the first positioner 132 and is arranged at one end of the second movable rod 133 close to the third movable rod, and is used to fix the third movable rod and the second movable rod 133 so as to adjust the extension or retraction length of the two.

[0042] In other embodiments, to enable greater length adjustment, the telescopic rod assembly 13 further includes a fourth movable rod, a fifth movable rod, and a sixth movable rod, as well as corresponding fourth, fifth, and sixth positioners. The fourth, fifth, and sixth movable rods have the same functions as the second movable rod 133, and the corresponding fourth, fifth, and sixth positioners have the same functions as the second positioner 134. Furthermore, the fourth, fifth, and sixth positioners are connected to the second positioner 134 in the same manner.

[0043] See also Figure 1 、 2 The electrode head 11 is equipped with two discharge needles 111, which are electrically connected to the cable 14. The discharge needles 111 are used to output high-voltage electricity to contact the animal. The discharge needles 111 are arranged at the ends of the electrode head 11. When the telescopic rod group 13 is extended or retracted, the discharge needles 111 can extend further relative to the fixed rod 12, increasing the working range. The telescopic rod group 13 can also retract the discharge needles 111, making the structure of the mechanism compact.

[0044] For details, please refer to Figure 1 、 2 The electrode head 11 is provided with a mounting hole 112 for fixedly connecting with one end of the telescopic rod group 13. One end of the telescopic rod group 13 is inserted into the mounting hole 112, and one end of the cable 14 running through the telescopic rod group 13 is located in the mounting hole 112, and the cable 14 is electrically connected to the discharge needle 111 of the electrode head 11. The cable 14 is located in the mounting hole 112 and is electrically connected to the electrode head 11. The mounting hole 112 surrounds the ends of the movable rods (first movable rod 131, second movable rod 133, etc.) of the telescopic rod group 13, and the outer sides of the movable rods are fixedly connected to the inner wall of the mounting hole 112.

[0045] Preferably, see Figure 1 、 2 , a fixing seat 113 for fixing the cable 14 is provided at one end of the telescopic rod group 13 close to the electrode head 11. The cable 14 is fixed by the fixing seat 113 to prevent the telescopic movement of the telescopic rod group 13 from causing entanglement or knotting of the cable 14. When the telescopic rod group 13 is fixedly connected to the electrode head 11, since the fixing seat 113 is provided at the end of the telescopic rod group 13, the fixing seat 113 is located in the mounting hole 112 after assembly. The fixing seat 113 is provided with a fixing hole through which the cable 14 passes. The cable 14 is electrically connected to the discharge needle 111 on the electrode head 11 through the fixing hole. Among them, the fixing hole of the fixing seat 113 fixes the cable 14, so that during the extension and retraction of the telescopic rod group 13, the movement of the cable 14 with the telescopic rod group 13 will not cause pulling on other components, such as pulling on the discharge needle 111.

[0046] Preferably, see Figure 1 、 2 The electrode head 11 is provided with a hanging hole 114 to facilitate the placement of the mechanism. In this application, the hanging hole 114 is designed between the discharge needles 111, and of course it can also be set on the outside of the electrode head 11, according to the actual situation.

[0047] Among them, see Figure 1 、 2Cable 14 is a spring wire that can cooperate with the extension and retraction of the telescopic rod assembly 13. Because the spring wire can extend under the action of tension and can retract on its own when not under force due to its own structure, cable 14 is a spring wire that can freely extend and retract with the telescopic rod assembly 13, and will not break, tangle, or knot during the extension and retraction process. When the movable rod of the lower level retracts to the movable rod or fixed rod of the upper level, the spring wire has its own elastic force to return, so it can retract in an orderly manner within the hollow structure of the movable rod or fixed rod 12, avoiding being squeezed together during the retraction process, resulting in getting stuck or blocked in the central control structure.

[0048] In other embodiments, see Figure 5 Since the cable 14 needs to perform telescopic movement simultaneously with the telescopic rod group 13, the cable 14 is fixed to one end of the telescopic rod group 13 close to the electrode head 11, and the other end is connected to the retractor 15. When the telescopic rod group 13 extends or retracts, it can drive the cable 14 to move, so that the retractor 15 cooperates with the telescopic rod group 13 to release or retract the cable 14. The retractor 15 is set near the end connected to the main unit by the fixed rod 12, or the retractor 15 is set on the main unit. The retractor 15 rotates to retract and release the cable 14. When the telescopic rod group 13 extends, the retractor 15 releases the cable 14; when the telescopic rod group 13 retracts, the retractor 15 retracts the cable 14. The length of the cable 14 released by the retractor 15 matches the length of the telescopic rod group 13.

[0049] An animal repellent device, see Figure 1 、 5 , 7, includes the above-mentioned discharge telescopic mechanism 10, and a host 20 connected to the telescopic mechanism 10. The cable 14 is electrically connected to the circuit board in the host 20, and is used to output high-voltage current to the electrode head 11. A connection hole 21 is provided at one end of the host 20. One end of the fixed rod 12 is fixedly connected to the connection hole 21; or, a mounting column is provided at one end of the host 20. The mounting column is inserted into the hollow structure of the fixed rod 12. Among them, the host 20 outputs high-voltage current through the electrode head 11. When the discharge needle 111 of the electrode head 11 contacts the animal, a high-voltage current is generated to the animal, thereby achieving the purpose of driving away the animal. In addition, the electrode head 11 and the host 20 are connected by a telescopic rod group 13. Since the telescopic rod group 13 can be extended or retracted, the electrode head 11 can cover a wider range of distances.

[0050] Specifically, the host 20 is connected to one end of the fixing rod 12 , and one end of the fixing rod 12 is inserted into the connecting hole 21 , or the hollow structure of the fixing rod 12 is inserted into the mounting column.

[0051] See also Figure 1 、5 7. The host 20 includes a housing 23, a circuit board 24 and a battery 25 arranged in the housing 23. The circuit board 24 is provided with a switch button 22. The switch button 22 is exposed on the housing 23 and can be a discharge button, a start button, etc. The housing 23 is a long strip structure and can be used as a handle of the device. The housing 23, the electrode head 11, the telescopic rod group 13 and the fixed rod 12 are all made of insulating materials to prevent

[0052] Compared with the prior art, the discharge needle 111 of the present device is arranged on the electrode head 11 and is connected to the main unit 20 through the telescopic rod group 13, so that the electrode head 11 can be extended to a larger distance under the action of the telescopic rod group 13; the telescopic rod group 13 adjusts the extended length through a positioner, with a simple structure and low production cost; the fixed rod 12 and the telescopic rod group 13 are both hollow structures, so the cable 14 connecting the discharge needle 111 can be freely retracted and extended, and when extending or retracting, the cable 14 is prevented from being entangled, causing the telescopic rod group 13 to extend and retract unsmoothly.

[0053] The above examples are merely used to further illustrate the technical content of the present invention for easier understanding by the reader. However, they do not limit the implementation of the present invention to these examples. Any technical extension or reinvention based on the present invention is protected by the present invention. The scope of protection of the present invention shall be determined by the claims.
