Technical Field

[0001] The present application relates to the technical field of electrical engineering equipment, and in particular to an electrical withstand voltage tester. Background Art

[0002] The electrical withstand voltage tester is an instrument used to test the durability and stability of electrical equipment under a certain pressure. It can measure the safety of electrical equipment under high voltage and promptly discover and solve potential problems, thereby ensuring the safety and reliability of electrical equipment.

[0003] An electrical withstand voltage tester is a test device that tests the withstand voltage of various electrical devices when used. For some small and light electrical devices, the tester can move them to the withstand voltage tester; but for some large and difficult to move electrical devices, the tester needs to move the withstand voltage tester to these devices for corresponding tests. However, the external shell of the commonly used withstand voltage tester is usually an integrated structure, which is inconvenient for the tester to carry the withstand voltage tester. Utility Model Content

[0004] The present application provides an electrical withstand voltage tester, which can facilitate testers to move the withstand voltage tester to some large electrical equipment to be tested.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0006] An electrical withstand voltage tester comprises a withstand voltage tester body, wherein a swing lever is respectively arranged on the left and right sides of the rear end of the withstand voltage tester body, and the two swing levers are symmetrical about the center point of the withstand voltage tester body;

[0007] The lower ends of the two swing rods are rotatably connected to the body of the withstand voltage tester, and the upper ends of the two swing rods are connected via a fixed cross bar;

[0008] A limit pull rod is symmetrically provided on the left and right sides of the front end of the withstand voltage tester body; the two ends of the limit pull rod are respectively connected to the middle position of the withstand voltage tester and the swing rod.

[0009] Furthermore, a first hanging ring is provided on the lower side of the middle position of the swing rod, and the limit pull rod is hung in the first hanging ring through a hook provided at the upper end thereof.

[0010] Furthermore, a fixing ring is provided at the lower end of the limiting pull rod, and the fixing ring at the lower end of the limiting pull rod is sleeved in a second hanging ring, and the second hanging ring is fixedly mounted on the side wall of one side of the pressure tester body through its mounting plate.

[0011] Furthermore, a plurality of limit buttons are evenly arranged on the lower side of the middle position of the left and right side walls of the withstand voltage tester body along the length direction of the side wall, and the axes of the limit buttons are perpendicular to the plane of the side wall of the withstand voltage tester body at which they are installed; the limit buttons can move freely along their own axial direction.

[0012] Furthermore, the structure of the limit button is the same as that of the self-locking button switch.

[0013] Furthermore, an avoidance groove is provided on one side of the swing rod close to the withstand voltage tester body, and the distance between the avoidance groove and the side wall of the withstand voltage tester body on the adjacent side is smaller than the length when the limit button pops out, and larger than the length when the limit button is in the pressed state.

[0014] Furthermore, a storage buckle is respectively provided on the left and right sides of the withstand voltage tester.

[0015] Furthermore, the hook on the limit pull rod is a dog buckle.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] When the electrical withstand voltage tester of the present application needs to be moved, the tester rotates the swing arm upwards to move the fixed cross bar to close to the top of the withstand voltage tester body, and then uses the limit pull rod to connect the swing arm and the withstand voltage tester body. In this way, a structurally stable triangular structure can be formed between the limit pull rod, the swing arm and the withstand voltage tester body. The tester can use the fixed cross bar to not only conveniently pick up the withstand voltage tester body and carry it to the large-volume electrical equipment to be tested, but also the withstand voltage tester body will not easily shake during the transportation process.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0025] like Figure 2 As shown, an electrical withstand voltage tester disclosed in the present application includes a withstand voltage tester body 1, and a swing rod 2 is respectively provided on the left and right sides of the rear end of the withstand voltage tester body 1, and the two swing rods 2 are symmetrical about the center point of the withstand voltage tester body 1; the lower ends of the two swing rods 2 are rotatably connected to the withstand voltage tester body 1, and the upper ends of the two swing rods 2 are connected by a fixed cross bar 3; a limit pull rod 4 is symmetrically provided on the left and right sides of the front end of the withstand voltage tester body 1; the two ends of the limit pull rod 4 are respectively connected to the middle position of the withstand voltage tester and the swing rod 2.

[0026] In the above embodiments, the front side of the withstand voltage tester body is its front panel with a screen, the side of the withstand voltage tester body 1 opposite to its front panel is the rear side, and the other two sides of the withstand voltage tester body 1 are its left and right sides. The two swinging rods 2 and the fixed cross bar 3 of the present application together form a handle of a U-shaped structure, and the structure as a whole can rotate around the connection point between the swinging rod 2 and the withstand voltage tester body 1. When the fixed cross bar 3 rotates to the top of the withstand voltage tester body 1 along with the two swinging rods 2, the tester can adjust the position of the limit pull rod 4 away from one end of the withstand voltage tester body 1, so that it can be connected to the swinging rod 2 on the corresponding side and restrain the swinging rod 2, so that the position of the swinging rod 2 can be limited by the limit pull rod 4.

[0027] When the tester needs to move the withstand voltage tester as a whole to a larger and immovable device, he can hold the fixed cross bar 3 with his hand and apply force upward to lift the withstand voltage tester body 1 away. Figure 1The pressure tester shown is a pressure tester with an outer shell as an integrally formed structure which is common in the prior art. Compared with this pressure tester, the pressure tester of the present application is easier to carry, and a stable triangular structure can be formed between the swing arm 2, the limit pull rod 4 and the pressure tester body 1 during use, which can avoid the pressure tester from shaking during the transportation process, thereby increasing the risk of it being bumped.

[0028] Furthermore, if Figure 2 As shown, a first hanging ring 5 is provided at the lower side of the middle position of the swing rod 2, and the limiting pull rod 4 is hung in the first hanging ring 5 through a hook 6 provided at the upper end thereof.

[0029] In the above embodiment, the limit rod 4 is hung in the first hanging ring 5 at the lower side of the middle position of the swing rod 2 through the hook 6 at the upper end thereof, so that there is a certain distance between the hook 6 at the upper end of the limit rod 4 and the fixed cross bar 3, thereby preventing the tester from being affected by the hook 6 at the upper end of the limit rod 4 when holding the fixed cross bar 3. And because the hook 6 at the upper end of the limit rod 4 is hung in the first hanging ring 5, it is very convenient whether the swing rod 2 and the limit rod 4 are connected or disconnected.

[0030] Furthermore, if Figure 2 and Figure 3 As shown, a fixing ring is provided at the lower end of the limiting pull rod 4, and the fixing ring at the lower end of the limiting pull rod 4 is sleeved in the second hanging ring 7, and the second hanging ring 7 is fixedly mounted on the side wall of one side of the withstand voltage tester body 1 through its mounting plate.

[0031] In the above embodiments, the limit rod 4 is movably connected to the second hanging ring 7 on the pressure tester body 1 through the fixing ring at its lower end. In this way, although the end of the limit rod 4 provided with the fixing ring is restricted by the second hanging ring 7 on the pressure tester body 1, so that the limit rod 4 will not be separated from the second hanging ring 7, the space inside the second hanging ring 7 can ensure that the limit rod 4 has sufficient freedom, which can facilitate the tester to adjust the position of the limit rod 4 as needed when using the limit rod 4.

[0032] Furthermore, if Figure 2-Figure 4 As shown, a plurality of limit buttons 8 are evenly arranged on the lower side of the middle position of the left and right side walls of the withstand voltage tester body 1 along the length direction of the side wall, and the axes of the limit buttons 8 are perpendicular to the plane of the side wall of the withstand voltage tester body 1 at which they are installed; the limit buttons 8 can move freely along their own axial direction.

[0033] In the above embodiments, the length of the swing rod 2 of the present application satisfies that it can smoothly rotate with the fixed cross bar 3 to the bottom of the withstand voltage tester body 1 around the connection point between itself and the withstand voltage tester body 1. When the swing rod 2 contacts one of the limit buttons 8, the swing rod 2 can be limited to prevent it from continuing to swing upward, so that the lower ends of the fixed cross bar 3 and the two swing rods 2 will support the front side of the voltage tester body at a certain angle, so that the panel on the front side of the voltage tester body is tilted upward, so that it is convenient for the tester to observe the data on the front panel of the voltage tester body and connect the relevant test circuits with the withstand voltage tester body. Since there are multiple limit buttons 8, and they are evenly arranged along the length direction of one of the side walls on the left and right sides of the withstand voltage tester body 1, if the tester wants to obtain the maximum tilt angle, it is necessary to pull out the limit button 8 farthest from the front side of the withstand voltage tester body 1 along its axis direction, and all the remaining limit buttons 8 are pressed into the withstand voltage tester body 1. In this way, when the swing arm 2 swings downward, it will stop when it encounters the limit button 8 farthest from the withstand voltage tester body 1. At this time, after the withstand voltage tester body 1 is placed on the working platform, the maximum tilt angle can be obtained through the swing arm 2 and the fixed cross bar 3. Similarly, if the withstand voltage tester body 1 is to be tilted to other angles, a limit button 8 at the corresponding position is pulled out of the withstand voltage tester body 1, and the remaining limit buttons 8 are all pressed into the withstand voltage tester body 1.

[0034] Furthermore, the structure of the limit button 8 is the same as that of the self-locking button switch.

[0035] In the above embodiments, the self-locking button switch is also called a self-locking switch. This button has a mechanical locking function. When the user presses it for the first time, the button will not jump up completely when the user releases it. At this time, the button is in a locked state. When the user presses the button again, the button will jump up completely and return to its original state. This structure of the switch is often used in the electrical field and belongs to the prior art, so the detailed working principle is not repeated here. The limit button 8 of the present application has the same structure as the self-locking button switch in the prior art, so the tester needs to make a certain limit button 8 of the present application limit the swing rod 2 that is rotated. When the other limit buttons 8 do not hinder the rotation of the swing rod 2, the tester can press the limit button 8 that needs to limit the swing rod 2 to fully extend the side wall of the withstand voltage tester body 1, and the remaining limit buttons 8 are all pressed into the withstand voltage tester body 1 by the tester, so that the swing rod 2 can smoothly stop at the limit button 8 at a specific position during the swinging process, which is very convenient to operate.

[0036] Furthermore, if Figure 3 and Figure 4As shown, an avoidance groove 9 is provided on the side of the swing rod 2 close to the withstand voltage tester body 1, and the distance between the avoidance groove 9 and the side wall of the withstand voltage tester body 1 on the adjacent side is smaller than the length when the limit button 8 pops out, and larger than the length when the limit button 8 is in the pressed state.

[0037] In the above embodiments, in order to facilitate the tester to smoothly press the limit button 8 in the locked state, there is usually still a certain distance between the limit button 8 in the locked state and the surface of the withstand voltage tester body 1. The avoidance groove 9 provided on the swing arm 2 in the present application allows the swing arm 2 to smoothly pass through the limit button 8 in the locked state when rotating. Since the distance between the avoidance groove 9 and the side wall of the withstand voltage tester body 1 on the adjacent side is smaller than the length of the limit button 8 in the fully pop-up state, the swing arm 2 can be blocked by the limit button 8 when it rotates to the limit button 8 in the fully pop-up state, thereby causing the withstand voltage tester body 1 to stay at a specific angle.

[0038] Furthermore, if Figure 3 and Figure 4 As shown, a storage buckle 10 is provided on the left and right sides of the withstand voltage tester respectively.

[0039] In the above embodiments, the storage buckle 10 can store the limiting pull rod 4 when the limiting pull rod 4 is in an idle state.

[0040] Furthermore, if Figure 2 and Figure 3 As shown, the hook 6 on the limit pull rod 4 is a dog buckle.

[0041] In the above embodiments, the dog buckle is a prior art, also known as a paparazzi buckle, a hook buckle, a lobster buckle, and a hook buckle, which is mainly used at the end of a bag strap or a lanyard to conveniently fix the strap to a D buckle or other round buckle. In the present application, the hook 6 on the limit pull rod 4 is designed as a dog buckle, so that the hook 6 on the limit pull rod 4 can be prevented from being separated from the first hanging ring 5 when in use.

[0042] The implementation principle of this embodiment is: if the tester wants to move the electrical withstand voltage tester of the present application to the front of the device to be tested, he can first rotate the swing rod 2 to rotate the fixed cross bar 3 to the top of the withstand voltage tester body 1, and then adjust the positions of the two limit pull rods 4 in turn, and hang the hooks 6 at their upper ends in the first hanging ring 5 under the swing rod 2 on the corresponding side, and then hold the fixed cross bar 3 with his hands to exert force to move the withstand voltage tester body 1 to the expected position. When conducting the test, if the tester needs to adjust the voltage tester body 1 so that its front panel is tilted upward, he can first press and adjust a limit button 8 corresponding to the required tilt angle of the voltage tester body 1 to make it pop out completely, and then press all the remaining limit buttons 8 into the voltage tester body 1, and then he can rotate the swing rod 2 again to make it contact with the fully popped-out limit button 8. At this time, the voltage tester body 1 can lift up its front side through the swing rod 2 and the fixed cross bar 3, so that its front panel is tilted upward, which is convenient for the tester to view the data and perform corresponding operations on the front panel of the voltage tester body 1.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
