Description

Technical Field

[0001] The invention relates to the technical field of anti-loosening clamps, in particular to an anti-loosening clamp and a use method thereof. Background Art

[0002] The main function of the utility pole bird repellent clamp is to stably fix the bird repellent on the pole crossbar to prevent it from loosening or falling off due to wind, rain or other reasons. In this way, the bird repellent can continue to effectively play its role in repelling birds and protect the safe operation of power lines. It is usually made of corrosion-resistant, high-strength, lightweight and durable materials, such as stainless steel and aluminum alloy. These materials can resist erosion in harsh outdoor environments and extend the service life of the clamp.

[0003] At present, when installing the bird repeller, most of them are installed on a U-shaped base, and then the U-shaped base is manually hung on the pole crossbar, and then the U-shaped base is locked on the pole crossbar by a screw. However, this operation requires power off, and the method of fixing by bolts requires power off when it needs to be disassembled after a period of time. If you choose not to disconnect the power and use the auxiliary insulating rod for disassembly, you need to install a screw sleeve suitable for the screw on the insulating rod, and then insert the screw sleeve on the insulating rod into the screw, and disassemble the screw by twisting the insulating rod and the screw sleeve. However, due to the high pole crossbar, it is difficult to align the screw sleeve with the end of the screw when disassembling using this method. It still needs to be raised and operated at a close distance. In addition, due to its structural characteristics, the bolts are prone to slipping and rusting and are difficult to disassemble. Therefore, even if this screw fixing method has the characteristics of easy installation, when the U-shaped base needs to be disassembled in a block, the disassembly is difficult and the operation is inconvenient, which has become a problem that needs to be solved urgently.

[0004] For this reason, we propose a kind of anti-loosening clamp and using method. Summary of the invention

[0005] The object of the present invention is to provide an anti-loosening clamp and a method of use to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solution: comprising a side U-shaped base and a connecting piece arranged on the side U-shaped base, after the bird repeller is installed through the connecting piece, the side U-shaped base is used to fix the bird repeller on the cross bar of the pole, characterized in that the anti-loosening clamp also includes:

[0007] A mounting box fixedly mounted on the side U-shaped base and having a cavity formed therein, and a clamping assembly and a parallelogram mechanism mounted on the mounting box, wherein the parallelogram mechanism is in transmission connection with the clamping assembly;

[0008] The locking mechanism is arranged between the parallelogram mechanism and the pole cross bar. After the side U-shaped base is placed on the pole cross bar, the parallelogram mechanism is pulled by the locking mechanism to make the clamping assembly contact the surface of the pole cross bar, thereby realizing the passive fixing action of the opposite side U-shaped base.

[0009] As a further description of the above technical solution: the installation box is provided with a slide groove integrally formed with the cavity, the clamping assembly includes two installation shafts slidably arranged in the slide groove and two intermediate rods respectively installed on the two installation shafts, the two intermediate rods are both equipped with a lifting clamping mechanism through a connecting pull rod, the two installation shafts are respectively connected to the two connecting rods of the parallelogram mechanism, and when the parallelogram mechanism is pulled downward by the locking mechanism to change the parallelogram mechanism from a compact state to an expanded state, the two installation shafts approach each other and pull the two lifting clamping mechanisms close to each other through the connecting pull rod until they are against the surface of the pole cross bar.

[0010] As a further description of the above technical solution: the lifting and clamping mechanism is installed on the clamping plate 1 on the installation box through a first lifting part, and the connecting pull rod connects the clamping plate 1 with the middle rod. When the two clamping plates 1 are brought close to each other through the connecting pull rod, the first lifting part increases the height of the two clamping plates 1. The lifting and clamping mechanism also includes a second lifting part arranged on the lifting plate 1 and installed with the clamping plate 2. When the two clamping plates 1 are brought close to each other, the second lifting part is used to increase the degree of lifting of the clamping plate 2 on the basis of the lifting of the clamping plate 1, thereby further expanding the clamping height.

[0011] As a further description of the above technical solution: the second lifting part includes a driving gear and a rack that are meshed with each other, and a bevel gear one and a bevel gear two that are meshed with each other, wherein the rack is arranged in a limiting groove, the driving gear is rotatably arranged on a clamping plate one, and the bevel gear two is connected to the surface of the rotating axis of the driving gear through a driving rod, and a lifting platform is threadedly installed on the bevel gear one through a screw rod, and the lifting platform is provided with a clamping plate two through a spring one, and the screw rod is rotatably arranged on the surface of the clamping plate one.

[0012] As a further description of the above technical solution: the locking mechanism includes a locking drive plate equipped with an elastic card and a pull rod running through the locking drive plate, the pull rod is connected to the parallelogram mechanism, and a plurality of card slot groups are provided at equal intervals on the surface of the pull rod, the elastic card is abutted in the card slot group, and a plurality of locking springs are fixedly arranged on the locking drive plate, when the side U-shaped base is hung on the pole cross bar, the locking drive plate is pushed upward, and the locking spring is abutted against the bottom surface of the pole cross bar.

[0013] As a further description of the above technical solution: the locking mechanism also includes a disassembly mechanism, which, when the U-shaped base on the opposite side is disassembled, resists upward against the locking drive plate. The disassembly mechanism rotates the elastic clamping plate to a vertical state, so that when the locking drive plate and the pull rod are relatively displaced, the elastic chuck will not resist the slot group.

[0014] As a further description of the above technical solution: a permanent magnet is also installed on the side U-shaped substrate through elastic damping. When the side U-shaped substrate is installed on the pole crossbar, the permanent magnet is used to assist the side U-shaped substrate to be fastened to the surface of the pole crossbar.

[0015] As a further description of the above technical solution: the anti-loosening clamp also includes an insulating operating rod, which is provided with a groove for inserting the pull rod when installing the side U-shaped base.

[0016] As a further description of the above technical solution: the static friction between the elastic card and the inclined surface of the card slot group is greater than the overall gravity of the anti-loosening clamp.

[0017] A method for using an anti-loosening clamp is applied to the above-mentioned anti-loosening clamp, and the method for using the anti-loosening clamp comprises the following steps:

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] See also Figure 1-9 The embodiment of the present invention provides a technical solution: comprising a side U-shaped base 2 and a connecting member 4 arranged on the side U-shaped base 2. After the bird repellent is installed through the connecting member 4, the side U-shaped base 2 is used to fix the bird repellent on the cross bar of the pole, characterized in that the anti-loosening clamp also includes:

[0038] A mounting box 3 fixedly mounted on the side U-shaped base 2 and having a cavity formed therein, and a clamping assembly and a parallelogram mechanism 35 mounted on the mounting box 3, wherein the parallelogram mechanism 35 is in transmission connection with the clamping assembly;

[0039] The locking mechanism is arranged between the parallelogram mechanism 35 and the pole crossbar. After the side U-shaped base 2 is placed on the pole crossbar, the parallelogram mechanism 35 is pulled by the locking mechanism to make the clamping assembly contact the surface of the pole crossbar, thereby realizing the passive fixing action of the side U-shaped base 2;

[0040] The installation box 3 is provided with a slide groove 34 integrally formed with the cavity, and the clamping assembly includes two installation shafts 38 slidably arranged in the slide groove 34 and two intermediate rods 39 respectively installed on the two installation shafts 38, and the two intermediate rods 39 are both installed with a lifting clamping mechanism through a connecting rod 36, and the two installation shafts 38 are respectively connected to the two connecting rods of the parallelogram mechanism 35, wherein the parallelogram mechanism 35 is composed of four connecting rods, and the adjacent two connecting rods are rotationally connected by a torsion spring, and the four connecting rods form a parallelogram that can be expanded and retracted. When the parallelogram mechanism 35 is retracted, the two connecting rods connected to the installation shafts 38 will approach each other, so that The two mounting shafts 38 are brought close to each other. It should also be noted that, when the torsion spring does not produce any deformation, the parallelogram mechanism 35 is in the initial state, at which time the distance between the two lifting and clamping mechanisms is also at the maximum state, and at this time the mounting shafts 38 on the two connecting rods of the parallelogram mechanism 35 are also at the maximum stroke of the slide slot 34, thereby limiting the parallelogram mechanism 35 to prevent the parallelogram mechanism 35 from shaking. When the parallelogram mechanism 35 is pulled downward by the locking mechanism so that the parallelogram mechanism 35 changes from a compact state to an expanded state, the two mounting shafts 38 are brought close to each other and the two lifting and clamping mechanisms are pulled close to each other by the connecting rod 36 until they are against the surface of the pole crossbar;

[0041] The lifting and clamping mechanism is installed on the clamping plate 31 on the installation box 3 through the first lifting part, and the connecting rod 36 connects the clamping plate 31 with the middle rod 39. When the two clamping plates 31 are brought close to each other through the connecting rod 36, the first lifting part raises the height of the two clamping plates 31, wherein the first lifting part includes a side mounting slide plate 37 fixedly arranged on the installation box 3 and provided with a limiting groove 317, the clamping plate 31 is slidably arranged in the limiting groove 317, and the limiting groove 317 is inclined. When the connecting rod 36 pulls the clamping plate 1 31, the two clamping plates 1 31 will slide along the inclined limiting groove 317 while approaching each other, so that the height of the clamping plate 1 31 in the vertical direction is increased. The lifting clamping mechanism also includes a second lifting part arranged on the lifting plate 1 and equipped with the clamping plate 2 33. When the two clamping plates 1 31 approach each other, the second lifting part is used to increase the lifting degree of the clamping plate 2 33 on the basis of the lifting of the clamping plate 1 31, so as to further expand the clamping height.

[0042] The second lifting part includes a driving gear 315 and a rack 316 that mesh with each other, and a bevel gear 1 312 and a bevel gear 2 313 that mesh with each other, wherein the rack 316 is arranged in a limiting groove 317, and the driving gear 315 is rotatably arranged on the clamping plate 1 31. When the two clamping plates 1 31 are brought close to each other by connecting the pull rod 36, the driving gear 315 rotates through the meshing structure with the rack 316, and the bevel gear 2 313 is connected to the surface of the rotating axis of the driving gear 315 through the driving rod 314. A lifting platform 311 is threadedly installed on the bevel gear 1 312 through a screw rod 310. The lifting platform 311 is provided with a clamping plate 2 33 through a spring 1 32, and the screw rod 310 is rotatably arranged on the surface of the clamping plate 1 31. When the driving gear 315 rotates, the driving rod 314 causes the bevel gear 2 313 to drive the bevel gear 1 312 to rotate, thereby rotating the screw rod 310. At this time, the lifting platform 311 moves upward on the screw rod 310 through the threaded structure with the screw rod 310, thereby driving the spring 1 32 and the clamping plate 2 33 to move upward. In this way, while the clamping plate 1 31 moves upward along the inclined limiting groove 317, the clamping plate 2 33 can also move further upward on the basis of the upward movement of the clamping plate 1 31, until the clamping plate 2 33 contacts the surface of the pole crossbar. When the two groups of clamping plates 1 31 and clamping plates 2 33 are at the maximum distance, the clamping plate 1 31 is at the bottom of the inclined limiting groove 317. And the lifting platform 311 is also at the bottom of the screw rod 310. At this time, the height of the clamping plate 1 31 and the clamping plate will not be higher than the side U-shaped base 2. At this time, when the side U-shaped base 2 is hung on the pole crossbar, the clamping plate 1 31 and the clamping plate 2 33 will not form an obstruction to prevent limitation. When the pole crossbar is clamped by the clamping plate 2 33, the clamping plate 1 31 rises, and the clamping plate 2 33 further rises on the basis of the raising of the clamping plate 1 31, thereby increasing the contact area between the clamping plate 2 33 and the pole crossbar, preventing the problem of the side U-shaped base 2 and the bird repellent thereon from loosening due to the small clamping surface and the unstable clamping, thereby enhancing the clamping effect and effectively avoiding the problem of inconvenient installation.

[0043] It should be noted that the locking mechanism includes a locking drive plate 5 with an elastic card 55 installed and a pull bar 52 running through the locking drive plate 5, the pull bar 52 is connected to the parallelogram mechanism 35, and a plurality of card slot groups 54 are evenly spaced on the surface of the pull bar 52, the elastic card 55 abuts against the card slot group 54, wherein the elastic card 55 can be a card plate rotated on the locking drive plate 5 by a torsion spring, or it can be an elastic sheet, which is a prior art and will not be described in detail here. The locking drive plate 5 is also fixedly provided with a plurality of locking springs 51, when the side U-shaped base 2 is hung on the pole cross bar, the locking drive plate 5 is pushed upward, and the locking spring 51 abuts against the bottom surface of the pole cross bar, and when the side U-shaped base 2 is hung on the pole cross bar When the U-shaped base 2 on the opposite side needs to be locked, the locking drive plate 5 is pushed upward to compress and deform the locking spring 51 that contacts the bottom surface of the pole crossbar. Since the elastic card 55 is tilted downward, and each slot in the slot group 54 has an inclined surface on one side and a flat surface on the other side, when the locking drive plate 5 is pushed upward, the elastic card 55 contacts the inclined surface on the slot group 54. At this time, the elastic card 55 is compressed and deformed, crossing the slot group 54. That is to say, the elastic card 55 and the slot group 54 and the main body pull strip 52 opened by the slot group 54 at this time do not produce much friction. Under the action of the torsion springs on each connecting rod on the parallelogram mechanism 35, the parallelogram structure does not undergo much deformation, but basically maintains the initial state. After the locking drive plate 5 rises to a certain height, the locking drive plate 5 is released. At this time, the locking spring 51 recovers a part of its deformation and pushes the locking drive plate 5 downward. The locking drive plate 5 moves downward until the elastic card 55 abuts against the plane of the uppermost slot group 54. The elastic card 55 and the slot group 54 are locked with each other. At this time, under the drive of the locking spring 51, the parallelogram mechanism 35 is pulled downward through the locking drive plate 5 and the pull bar 52, so that the parallelogram mechanism 35 is unfolded, so that the two connecting rods of the parallelogram mechanism 35 pull the two mounting shafts 38 closer to each other, so that the clamping plate 1 31 and the clamping plate 2 33 are closer to each other, until the clamping plate 2 33 abuts against the surface of the pole crossbar. At this time, due to the abutment of the clamping plate 2 33, the spring 1 32 is also contracted. The elastic force of the spring 1 32 is used to enhance the contact force between the clamping plate 2 33 and the pole cross bar, thereby enhancing the clamping effect. The clamping plate 2 33 is made of a material with a large friction coefficient, which can be fluororubber, which has a large friction coefficient and has better corrosion resistance outdoors. It can also be ceramic, which has a larger friction coefficient and can be used in situations where a heavier bird repellent is installed. At this time, under the action of multiple parties, the elastic deformation of the spring 1 32 causes the clamping of the clamping plate 2 33 with a larger friction coefficient and the pole cross bar. At this time, the locking spring 51 in the state of restoring the deformation does not completely restore the deformation, but balances with the elastic force of the spring 1 32. It also contacts the bottom of the pole cross bar through the elastic force. Under the action of these parties, the clamping of the opposite U-shaped base 2 is achieved.And the clamping effect is excellent, suitable for promotion and use;

[0044] The locking mechanism also includes a disassembly mechanism. When the U-shaped base 2 on the opposite side is disassembled, it contacts the locking drive plate 5 upwards. The elastic card plate is rotated to a vertical state through the disassembly mechanism, so that when the locking drive plate 5 and the pull bar 52 are relatively displaced, the elastic card plate will not contact the card slot group 54. In one embodiment, the disassembly mechanism includes a support plate 53 fixedly set on the pull bar 52 and a push rod 56 slidably set on the locking drive plate 5. When the U-shaped base 2 on the opposite side is disassembled and the locking drive plate 5 is pushed upwards, the locking spring 51 on the locking drive plate 5 is compressed and deformed, and the elastic card 55 is separated from the uppermost card slot group 54. The pull bar 52 between the bottom plate and the uppermost card slot group 54 is a smooth part. When the elastic card 55 has a tendency to separate from the card slot group 54, the parallelogram machine The mechanism 35 gradually recovers under the action of the torsion spring until the parallelogram mechanism 35 returns to its initial state. At this time, the locking drive plate 5 continues to be pushed upward. Since the friction between the elastic card 55 and the smooth part of the pull bar 52 is less than the force required to rotate the torsion spring of the parallelogram mechanism 35, the pull bar 52 no longer moves upward at this time until the push rod 56 hits the abutment plate 53, and the abutment plate 53 presses the push rod 56 downward, and the push rod 56 slides downward, squeezing the elastic card 55 to deflect the elastic card 55, and the lock is released at this time. The locking plate 5 is tightened, and the locking spring 51 recovers its deformation to push the locking plate 5 downward. Since the elastic card 55 no longer contacts the card slot group 54 at this time, the locking plate 5 and the pull rod 52 are relatively displaced until the locking spring 51 is separated from the pole cross bar. At this time, the side U-shaped base 2 can be removed from the pole cross bar. Compared with the disassembly method of using a screw to fix it, the screw sleeve on the insulating rod needs to be aligned with the screw and the screw is twisted during disassembly. The present invention can directly unlock the locked side U-shaped base 2 by means of the locking driving plate 5 with a larger contact area. The staff can use the insulating rod on the ground to conveniently operate, without sophisticated operation requirements, and there will be no problems such as rust or stripping of the screw, and there is no need to climb or lift the staff by lifting equipment. During installation, there is no need to twist the screw across the long insulating operating rod 8, but the installation of the opposite side U-shaped base 2 can be achieved in a more labor-saving pushing manner, which undoubtedly reduces the labor intensity during long-term operation.

[0045] In order to further improve the installation effect of the side U-shaped base 2, a permanent magnet 7 is also installed on the side U-shaped base 2 through an elastic damper 6. When the side U-shaped base 2 is installed on the pole crossbar, the permanent magnet 7 is used to assist the side U-shaped base 2 to be fastened to the surface of the pole crossbar;

[0046] The anti-loosening clamp also includes an insulating operating rod 8, on which a groove is provided for inserting the pull rod 52 when installing the side U-shaped base 2. It should be noted that when disassembling, if the side U-shaped base 2 and the bird repeller do not need to be recovered, there is no need to insert the pull rod 52 into the groove, but directly push the locking drive plate 5 upward, and after the unlocking operation, it can be directly peeled off from the pole crossbar. If the side U-shaped base 2 needs to be recovered, the end of the pull rod 52 needs to be inserted into the groove, and in order to facilitate the insertion, the width of the groove can be opened to facilitate the staff to insert the pull rod 52 on the ground, and an extrusion plate can be set in the groove by rotating the torsion spring, and the width of the larger groove is not required. It needs to be aligned and directly plugged in. After the plugging, the torsion spring is deformed when it is sleeved along the extrusion plate until the plane of the extrusion plate abuts against the surface of the pull rod 52. At this time, the pull rod 52 is clamped by the extrusion plate. In order to enable the end of the insulating operating rod 8 to move to abut against the surface of the locking drive plate 5 after clamping, a pulley can also be set on the surface of the extrusion plate that pushes the locking drive plate 5 upward, or grease can be applied. In this way, when the U-shaped base 2 on the recovery side is recovered, there is no need to perform an alignment operation, but the extrusion plate is clamped adaptively, which is convenient for the recovery of the U-shaped base 2 on the opposite side and the bird repeller;

[0047] The static friction between the elastic card 55 and the inclined surface of the card slot group 54 is greater than the overall gravity of the anti-loosening clamp. When installing the U-shaped base 2 on the opposite side, the end of the pull rod 52 is first inserted into the groove on the insulating operating rod 8, and the end of the insulating operating rod 8 is made to contact the surface of the locking drive plate 5, and then the side U-shaped base 2 is hung on the pole crossbar through the insulating operating rod 8. In this process, since the static friction between the elastic card 55 and the inclined surface of the card slot group 54 is greater than the overall gravity of the anti-loosening clamp, when lifting, the inclined surface of the card slot group 54 can be used to limit the elastic card 55 to a certain extent, so that The pull bar 52 and the locking drive plate 5 are relatively fixed until the U-shaped base on the opposite side is hung. The locking drive plate 5 is pushed upward by external force through the insulating operating rod 8, and the locking spring 51 contacts the cross bar of the pole. At this time, the external force is greater than the maximum limit of the static friction force between the elastic card 55 and the inclined surface of the card slot group 54, and a relative displacement occurs between the locking drive plate 5 and the pull bar 52. This arrangement can prevent the locking drive plate 5 from being restricted when the anti-loosening clamp is lifted upward by the insulating operating rod 8, resulting in the locking spring 51 being too high. This prevents the spring from being too high and affecting the hanging of the U-shaped base 2 on the opposite side, and has better practicality.

[0048] When the locking plate 5 is in the upper part, the locking spring 51 is in the lower part, and the locking spring 51 is in the lower part, so that the locking plate 5 is in the lower part, and ...

[0049] A method for using an anti-loosening clamp is applied to the above-mentioned anti-loosening clamp, characterized in that the method for using the anti-loosening clamp comprises the following steps:

[0050] Step 1: Adjust the locking drive plate 5 to the middle position of the slot group 54 on the pull rod 52, and insert the pull rod 52 into the slot on the insulating operating rod 8;

[0051] Step 2: Lift the anti-loosening clamp through the insulating operating rod 8, and hang the side U-shaped base 2 on the crossbar of the pole;

[0052] Step three: Use the insulating operating rod 8 to squeeze the locking drive plate 5 upward so that the locking spring 51 contacts the bottom surface of the pole crossbar and deforms until the vibration effect on the insulating operating rod 8 disappears, and then pull out the insulating operating rod 8. At this time, the installation of the opposite U-shaped base 2 and the bird repeller is completed through the locking mechanism and the clamping assembly.

[0053] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
