[0037] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0038] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the scope of the present application, therefore the present application is not limited to the specific embodiments disclosed below.
[0039] Second, the "one embodiment" or "an embodiment" referred to herein can include a particular feature, structure, or characteristic. The various embodiments appearing at different places in this specification can not all refer to the same embodiment or to the same implementations or alternatives of an embodiment.
[0040] Embodiment 1
[0041] With reference to Figures 1-4 For the first embodiment of the present application, the embodiment provides a multifunctional test wiring rod, which can realize the effect of convenient wiring use, comprising: a wiring assembly 100 and an auxiliary assembly 200.
[0042] Specifically, the wiring assembly 100 comprises a wiring rod body 101, an insulating mounting block 102 arranged at the end of the wiring rod body 101, and a contact component 103 arranged on one side of the insulating mounting block 102. The wiring rod body 101 is made of insulating material, and the contact component 103 is blocked by the insulating mounting block 102 to prevent electric conduction danger.
[0043] Further, the auxiliary assembly 200 comprises a bracket component 201 mounted on one side of the wiring rod body 101, an observation recorder 202 detachably mounted on one side of the bracket component 201 and arranged towards the contact component 103, and a wire binding component 203 arranged on the surface of the wiring rod body 101. The observation recorder 202 has a camera and signal transmission function, so that the operator operating the wiring rod body 101 below can observe the target scene above through wired or wireless signal, which is convenient for the test hook 103a to be connected with the test equipment.
[0044] Among them, the contact component 103 comprises test hooks 103a mounted on both sides of the insulating mounting block 102, wire clamping grooves 103b arranged on the side of the test hooks 103a, and pincer flake 103c arranged at the hook opening position of the test hooks 103a. The test wires at the current and voltage ends are clamped on the wire clamping grooves 103b respectively, and the resistance is increased by the concave groove body to prevent falling off; the test hook 103a is inverted hook-shaped, which strengthens the hanging reliability; the pincer flake 103c is in the form of a cutting sheet and is located at the hook tip of the test hook 103a, which facilitates positioning and friction cutting, solves the problem of large contact resistance, and makes it difficult to frictionally remove the paint or dirt on the contact surface of the test equipment to affect the test data accuracy.
[0045] Further, the bracket component 201 comprises a rotating shaft 201a connected to one side of the insulating mounting block 102, a rotating rod 201b arranged on one side of the rotating shaft 201a and matched with the surface of the connecting rod body 101, and a mounting bracket 201c arranged on one side of the rotating rod 201b for mounting the observation recorder 202. The observation recorder 202 is mounted on the mounting bracket 201c, and the rotating rod 201b is pushed to make the observation recorder 202 make a circular motion relative to the rotating shaft 201a. The circular motion of the observation recorder 202 can ensure that the direction is always opposite to the test hook 103a, and the angle of view opposite to the test hook 103a can be adjusted by pushing the rotating rod 201b, so as to bypass the dead angle of view. The rotating shaft 201a can be a damping shaft, which has a large frictional resistance and can be automatically fixed by using the resistance to offset the influence of its own gravity when rotated to a certain angle.
[0046] Preferably, the binding component 203 comprises a connecting column 203a arranged on the surface of the connecting rod body 101, a non-slip pad 203b arranged on the surface of the connecting column 203a, a binding belt 203c arranged on one side of the connecting column 203a, and a fastener 203d arranged on the side of the binding belt 203c. The non-slip pad 203b is made of soft and elastic material, which can not only prevent the test line from being damaged after being compressed, but also provide a large frictional resistance when being compressed to prevent the test line clamp from falling off from the wire clamping groove 103b due to pulling the test line. The fastener 203d can fix the tightened binding belt 203c to prevent loosening. In this embodiment, the magic tape is used, and the existing means such as lock buckle and knot can also be used for locking.
[0047] Working principle: in use, the test line clamps of the current and voltage ends are respectively clamped on the wire clamping groove 103b, the resistance is increased by the concave groove body to prevent falling off, a section of the test line is reserved and then bound tightly at the connecting column 203a by the binding belt 203c, and fixed by the fastener 203d. The non-slip pad 203b made of soft material can not only prevent the test line from being damaged after being compressed, but also provide a large frictional resistance when being compressed to prevent the test line clamp from falling off from the wire clamping groove 103b due to pulling the test line. Then, the observation recorder 202 is mounted on the mounting bracket 201c, and the rotating shaft 201a is adjusted to make the observation recorder 202 face the appropriate direction to bypass the blind area of view. The operator operates the connecting rod body 101 through the image transmitted by the observation recorder 202 from below, so that the test hook 103a is connected with the tested device, and the measured surface oxide layer or paint film is cut by the jaw sheet 103c at the hook opening position of the test hook 103a. Finally, the test detection is performed on the connected circuit.
[0048] In summary, by setting the wiring assembly 100 and the auxiliary assembly 200 to be used in cooperation, the hook-shaped contact part 103 is used to increase the hanging reliability, the observation recorder 202 is installed and the binding part 203 is set to have the effect of high observation and prevent the wire clamp from falling off, and the problems of large contact resistance and poor hanging reliability are solved.
[0049] Embodiment 2
[0050] Reference Figures 5-11 For the second embodiment of the application, unlike the previous embodiment, the embodiment provides an adjusting assembly 300 to solve the problem that the observation recorder 202 cannot be adjusted in time to assist operation due to the length of the wiring rod body 101.
[0051] Specifically, the end of the wiring rod body 101 is further provided with an adjusting assembly 300, and the adjusting assembly 300 includes a lengthening part 301 arranged at the end of the wiring rod body 101, a calibration part 302 arranged at one end of the lengthening part 301 and matched with the rotating shaft 201a, and a supporting part 303 arranged at the other end of the lengthening part 301. The lengthening part 301 is arranged to lengthen the wiring rod body 101, which is convenient for docking with the test equipment at a higher place. After the wiring rod body 101 is too long, the observation recorder 202 is needed to obtain the image at the docking position to facilitate operation. The calibration part 302 is arranged to calibrate the shooting angle of the observation recorder 202 at a high place. The supporting part 303 is arranged to be placed on the ground surface, and the lengthening part 301 is arranged to lengthen the wiring rod body 101, so that the supporting part 303 can be placed on the ground surface, and the limited number of operators have the opportunity to loosen the wiring rod body 101 to perform other necessary operations, thereby providing convenience.
[0052] Further, the lengthening part 301 includes an adjusting column 301a rotatably connected to the end of the wiring rod body 101, a threaded column 301b arranged in the wiring rod body 101 and threadedly connected with the adjusting column 301a, a guide strip 301c arranged on the inner wall of the wiring rod body 101, and a limiting part 301d arranged at one side of the threaded column 301b and matched with the guide strip 301c. When the length of the wiring rod body 101 is not enough, the adjusting column 301a is rotated, the adjusting column 301a is rotated to drive the threaded column 301b to move along the direction of the guide strip 301c under the cooperation of the limiting part 301d and the guide strip 301c, so that the threaded column 301b reserved in the wiring rod body 101 is moved out to lengthen.
[0053] The calibration part 302 comprises a telescopic rod 302a rotatably connected to the end of the threaded column 301b, a first linkage gear 302b arranged on one side of the telescopic rod 302a, a worm 302c rotatably connected to one side of the insulating mounting block 102, a second linkage gear 302d arranged on one side of the worm 302c and matched with the first linkage gear 302b, a worm wheel 302e rotatably connected to the inner side of the insulating mounting block 102 and matched with the worm 302c, and a calibration gear 302f arranged on one side of the rotating shaft 201a and matched with the worm wheel 302e. The telescopic rod 302a is rotatably connected to the threaded column 301b, so that the threaded column 301b is prevented from rotating and driving the telescopic rod 302a to rotate during the process of stopping the downward pulling of the switching block 301d-6g, rotating the adjusting column 301a and making the limiting block 301d-2 re-slidingly connected to the guide strip 301c, so that the shooting angle of the observation recorder 202 just adjusted is prevented from being changed again. When the worm 302c is matched with the worm wheel 302e, only the worm 302c can drive the worm wheel 302e to rotate, and the worm wheel 302e cannot drive the worm 302c to rotate in the opposite direction and is blocked, so that the rotating shaft 201a is prevented from being deviated and the shooting angle is prevented from being changed by accidental interference.
[0054] Further, the limiting part 301d comprises a groove 301d-1 formed in the threaded column 301b near one end of the telescopic rod 302a, a limiting block 301d-2 slidingly connected in the groove 301d-1 and matched with the guide strip 301c, a first spring 301d-3 connected between the limiting block 301d-2 and the threaded column 301b, a first inclined groove 301d-4 formed on the outer side of the limiting block 301d-2, a pressing block 301d-5 connected on one side of the limiting block 301d-2 and matched with the telescopic rod 302a, and a switching part 301d-6 arranged on one end of the threaded column 301b close to the supporting part 303. When the limiting block 301d-2 moves into the groove 301d-1, the pressing block 301d-5 on one side of the limiting block 301d-2 will press the telescopic rod 302a, so that when the adjusting column 301a is rotated, the threaded column 301b will be driven to rotate through the thread cooperation and drive the telescopic rod 302a to rotate through the friction force generated by the pressing.
[0055] The switching piece 301d-6 comprises a second inclined groove 301d-6a formed in the bottom of the limiting block 301d-2 and arranged towards the guide strip 301c, an extrusion rod 301d-6b slidably connected in the interior of the threaded column 301b and matched with the second inclined groove 301d-6a, a first gear rack 301d-6c arranged at one end of the extrusion rod 301d-6b close to the support part 303, a switching gear 301d-6d rotatably connected in the interior of the threaded column 301b and matched with the first gear rack 301d-6c, and a second gear rack 301d-6e slidably connected at one side of the threaded column 301b and matched with the switching gear 301d-6d. The maximum extension length of the threaded column 301b is arranged to ensure that the height of the final adjusting column 301a relative to the bottom support part 303 conforms to the ergonomics, so as to facilitate personnel operation.
[0056] Preferably, the first gear rack 301d-6c is connected with the interior of the threaded column 301b through a second spring 301d-6f, and the second gear rack 301d-6e is arranged with a switching block 301d-6g towards the outside of the threaded column 301b. At the same time, since the switching block 301d-6g is arranged at the lowermost part of the threaded column 301b, and the height of the support part 303 itself is also limited, when the support part 303 is placed on the ground, the operator can observe and record the adjustment of the direction of the observation instrument 202 by stepping on the switching block 301d-6g with the foot and simultaneously twisting the adjusting column 301a with the hand.
[0057] The rest of the structure is the same as that of Embodiment 1.
[0058] Working principle: when the length of the wiring rod body 101 is not enough, the adjusting column 301a is rotated, the adjusting column 301a is rotated to drive the threaded column 301b to move along the direction of the guide strip 301c under the cooperation of the limiting block 301d-2 and the guide strip 301c, so that the threaded column 301b reserved in the interior of the wiring rod body 101 is moved out for lengthening;
[0059] When the length of the connecting rod body 101 reaches a certain limit, it is inconvenient to manually rotate the rotating rod 201b directly to adjust the shooting angle of the observation recorder 202. At this time, the switching block 301d-6g is pulled down, the second rack 301d-6e is driven to move down, the second rack 301d-6e moves down to drive the switching gear 301d-6d to rotate, the switching gear 301d-6d rotates to drive the first rack 301d-6c to move up and compress the second spring 301d-6f, the first rack 301d-6c moves up to drive the extrusion rod 301d-6b to move up, and the extrusion rod 301d-6b moves up to extrude the second inclined groove 301d-6a at the bottom of the limiting block 301d-2, so that the limiting block 301d-2 is subjected to a horizontal component force, thereby driving the limiting block 301d-2 to slide inward along the groove 301d-1 and compress the first spring 301d-3. When the limiting block 301d-2 moves into the groove 301d-1, the limiting block 301d-2 no longer limits the guide bar 301c. At this time, the adjusting column 301a is rotated, and the threaded column 301b will not move along the direction of the guide bar 301c, but will rotate with the adjusting column 301a;
[0060] At the same time that the limiting block 301d-2 moves into the groove 301d-1, the extrusion block 301d-5 on one side of the limiting block 301d-2 will compress the telescopic rod 302a. Therefore, when the adjusting column 301a is rotated, the threaded column 301b will rotate by screwing and will drive the telescopic rod 302a to rotate by the friction force generated by the compression, the telescopic rod 302a will rotate to drive the first linkage gear 302b to rotate, the first linkage gear 302b will rotate to drive the second linkage gear 302d to rotate, the second linkage gear 302d will rotate to drive the worm 302c to rotate, the worm 302c will rotate to drive the worm wheel 302e to rotate, the worm wheel 302e will rotate to drive the calibration gear 302f to rotate, and the calibration gear 302f will rotate to drive the coaxial rotating shaft 201a to rotate, thereby adjusting the shooting angle of the observation recorder 202 through the rotating rod 201b;
[0061] When the angle is adjusted to the appropriate angle, immediately stop the downward movement of the switching block 301d-6g, reset the second spring 301d-6f, and drive the switching block 301d-6g and the second rack 301d-6e to move upward, while the first rack 301d-6c and the pressing rod 301d-6b move downward and no longer press the second inclined groove 301d-6a at the bottom of the limiting block 301d-2, and the limiting block 301d-2 will reset and slide outward along the groove 301d-1 under the elastic force of the first spring 301d-3. At this time, the threaded column 301b rotates, and the limiting block 301d-2 may not be in sliding cooperation with the guide strip 301c, and the adjusting column 301a needs to be continuously rotated to drive the threaded column 301b to rotate, so that the limiting block 301d-2 performs a circular motion. The limiting block 301d-2 performs a circular motion until the first inclined groove 301d-4 on the outside is pressed by the guide strip 301c, thereby generating a transverse component force to compress the first spring 301d-3 and make the limiting block 301d-2 slide into the groove 301d-1. After the limiting block 301d-2 slides, it is out of position with the guide strip 301c, and the pressing force disappears immediately, so that the first spring 301d-3 resets, and the limiting block 301d-2 slides out to complete the sliding connection with the guide strip 301c, without affecting the subsequent need to adjust the length.
[0062] In summary, by setting the adjusting assembly 300, the length of the wiring rod body 101 and the orientation of the observation recorder 202 can be adjusted at any time, solving the problem that the orientation of the observation recorder 202 cannot be adjusted at any time to assist in operation due to the length of the wiring rod body 101.
[0063] Embodiment 3
[0064] Reference Figures 12-14 For the third embodiment of the present application, unlike the previous embodiment, the embodiment provides a support part 303 that can be stored and stably placed.
[0065] In most scenarios, the test hook 103a above the wiring rod body 101 can resist the tested device, while the support part 303 below can resist the ground, and rotating the adjusting column 301a to lengthen the wiring rod body 101 will make the upper and lower ends tightly resist, making it easy to loosen the wiring rod body 101. In order to adapt to more application scenarios, the support part 303 also needs to have the ability to stably support and place.
[0066] Specifically, the support part 303 comprises a support rod 303a detachably connected at the end of the threaded column 301b, a support plate 303b rotatably connected at the side of the support rod 303a, a torsion spring 303c connected between the support plate 303b and the support rod 303a, a limiting rod 303d slidably connected at the end of the support rod 303a, a third spring 303e connected between the limiting rod 303d and the support rod 303a, and a limiting sleeve 303f arranged at the end of the limiting rod 303d and matched with the support rod 303a. When it is needed to be stored, the limiting sleeve 303f is pulled first, then each group of support plates 303b is folded, and then the limiting sleeve 303f is loosened, so that the limiting sleeve 303f is pressed to the bottom of the support rod 303a under the elastic force of the third spring 303e, and the limiting sleeve 303f is blocked by the support plate 303b, and the side of each group of support plates 303b is blocked by the inner side wall of the limiting sleeve 303f, so as to keep balance and complete storage.
[0067] Further, the maximum rotation angle of the support plate 303b relative to the limiting rod 303d is 90°, and the bottom surface of the support plate 303b when rotated by 90° is flush with the bottom surface of the limiting sleeve 303f at this time. The support plate 303b can be stored when it is rotated to the vertical state, and the support plate 303b can be stably placed when it is rotated to the horizontal state, reducing the occurrence of the inverted rod.
[0068] The rest of the structure is the same as that of Embodiment 2.
