Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.

The inventors expect the performance of the vacuum interrupter 1 arriving at the customer site to be consistent with the factory performance, and as such, the inventors thought that some work would be required during long-distance transportation of the vacuum interrupter 1. The inventor has thought, after inventive work, to avoid possible surface friction between the stationary and movable contacts in the closed state during long-distance transport of the vacuum interrupter 1. As can be understood by those skilled in the art, in the closed state, i.e., the state where the vacuum interrupter 1 is not subjected to an external force, the stationary contact and the movable contact are closed, i.e., the stationary contact blade and the movable contact blade are attached to each other. In this way, the vacuum interrupter 1 is provided with the adapter 2 so that the movable contact can be held in a state of being separated from the stationary contact.

As shown in fig. 1 and 2, the adapter 22 includes a support body 21 and a fastening assembly 22. Wherein the supporting body 21 is used to be disposed at an end of the moving contact rod 132 away from the fixed contact, the supporting body 21 is also used to support the fastening component 22, and the fastening component 22 can be fixed on the moving contact rod 132 and keep the moving contact 13 at a position separated from the fixed contact.

The supporting body 21 of the present embodiment may be a hollow component with any shape, and it may be covered on one end of the moving contact rod 132 away from the fixed contact, specifically, the supporting body 21 is, for example, a hollow cylinder as shown in fig. 1 and fig. 2, but of course, a hollow cube, a polygonal cylinder, etc., may also be used, and is not limited in particular. The top of the supporting body 21 may have a top cover 211, and the bottom of the supporting body 21 may have a bottom plate or no bottom plate, which may be set according to actual requirements, and the supporting body 21 in fig. 1 and 2 is a case without a bottom plate. The top cover 211 of the supporting body 21 has a through hole 212, the supporting body 21 is used for covering the moving contact rod 132 and is disposed at one end of the housing 11 close to the moving contact, and the fastening component 22 penetrates through the supporting body 21 through the through hole 212, so as to realize the fixed connection with the moving contact rod 132. The structure is simple and convenient to realize.

Under the condition that the movable contact is in contact with the fixed contact and in the state that the supporting body 21 is arranged at one end of the movable contact rod far away from the fixed contact, the lower surface of the top cover 211 of the supporting body 21 is spaced from the top end of the movable contact rod 132. Thus, the moving contact rod 132 has enough space to be pulled up to separate the moving contact from the stationary contact. Fig. 3 to 6 show a case where a part of the movable contact rod 132 is exposed from the housing 11, and thus it is necessary that the distance between the lower surface of the top cover 211 of the support body 21 and the bottom of the support body 21 is longer than the length of the part of the movable contact rod 132 exposed from the housing 11. When the support body 21 is covered on the movable contact rod 132, the movable contact rod 132 can move within the support body 21, for example, to abut against the lower surface of the top cover 211 of the support body 21. Optionally, the fastening assembly 22 has an external thread at one end for fixing the movable contact rod 132, and the movable contact rod 132 has a screw hole 1321 at the end far away from the fixed contact 12; or the fastening assembly 22 has a screw hole 1321 at one end for fixing the movable contact rod 132 and an external thread at one end of the movable contact rod 132 away from the fixed contact 12. In this way, the fastening assembly 22 and the movable contact rod 132 are fixed by means of screw coupling, which is simple and convenient to assemble.

Alternatively, the fastening assembly 22 includes a bolt 221, the bolt 221 has a first head 2211 and a first screw 2212, the first screw 2212 is fixed to the first head 2211, the diameter of the first head 2211 is larger than that of the through hole 212, the diameter of the screw 2212 is smaller than that of the through hole 212, and the first screw 2212 is used for fixing the moving contact rod 132. As shown in fig. 1, the screw 2212 can be inserted through the through hole 212 and extend into the screw hole 1321 of the movable contact rod 132.

Optionally, the fastening assembly 22 further comprises a spring washer 222 and a flat washer 223, wherein the spring washer 222 is configured to fit over the screw 2212; the flat washer 223 is used to fit over the screw 2212, and the flat washer 223 is used to be interposed between the spring washer 222 and the support body 21.

Alternatively, as shown in fig. 1 and 2, the lateral surface of the supporting body 21 has two symmetrical hollowed-out portions 213. Due to the existence of the hollow-out portion 213, an operator can use a tool to clamp the movable contact rod 132 through the hollow-out portion 213 so as not to rotate, and then move the movable contact rod 132 to a direction away from the fixed contact through the movable fastening assembly 22, that is, lift up in fig. 1, so that damage to other components inside the vacuum switch tube 11 due to rotation of the movable contact rod 132 can be avoided, and the operator can observe the moving condition of the movable contact rod 132 from the hollow-out portion 213. Specifically, the distance between the two hollow portions 213 is smaller than or equal to the diameter of the moving contact rod 132, or as shown in fig. 2, one end of the moving contact rod 132 away from the fixed contact has two symmetrical notches 1322, and the distance between the notches 1322 is greater than or equal to the distance between the two hollow portions 213, so that the notches 1322 may face the two hollow portions 213, and the notches 1322 form a certain plane, which is convenient for being clamped.

Since the adapter 2 needs to be installed when shipped from a factory and the adapter 2 needs to be removed when arriving at a customer, a tool suitable for the adapter 2 is needed, and the tool can prevent the movable contact rod from rotating during the process of installing the adapter 2 or removing the adapter 2, so as to avoid the damage of other parts in the vacuum switch tube 11, such as the damage of a corrugated tube.

Example one

The embodiment provides a tool for a vacuum switch tube, which is used for limiting the rotation of a movable contact rod.

As shown in fig. 3 to 6, the structure of the tool for a vacuum switch tube according to the present embodiment is schematically illustrated. The tool for the vacuum switch tube comprises a base 31, a sliding rail 32, a rotating mechanism 33, a vertical adjusting mechanism 34 and a clamping mechanism 35.

Wherein the base 31 has a first plane 311. Below the first plane 311 there are several support feet 312, four support feet 312 being shown in fig. 3 and 4. The support leg 312 can support the first plane 311 for easy transportation.

There are many implementations of the slide rail 32, and fig. 3 and 4 show one implementation, namely, a single slide rail implementation, but a double slide rail implementation may also be used, and is not limited in particular.

The rotating mechanism 33 is located on the slide rail 32 and can move along the slide rail 32, the rotating mechanism 33 is used for carrying the vacuum switch tube 1, and the rotating mechanism 33 can rotate along the direction perpendicular to the first plane 311. After the vacuum interrupter 1 is placed on the rotating mechanism 33, the moving contact bar is perpendicular to the first plane 311. Furthermore, the vacuum interrupter 1 can be moved in the first direction L1 due to the slide rail 32. The rotating mechanism 33 is, for example, a turntable, which can rotate along its axis, as shown in fig. 3 to 6. By this rotating mechanism 33, the alignment direction between the movable contact bar and the clamping mechanism 35 can be adjusted so that the position at which the movable contact bar is clamped can be fitted to the clamping mechanism 35. Fixing members (not shown) for fixing the position of the rotating mechanism 33 may be provided at both ends of the slide rail 32, so that the rotating mechanism 33 is prevented from being displaced. The fixing member can be implemented in various ways, such as grasping the fixing member with a hand grip or clamping the fixing member, and will not be described herein.

The vertical adjustment mechanism 34 is located on the first plane 311 and on an extension line of the slide rail 32 in the first direction L1, and the vertical adjustment mechanism 34 is movable in a direction perpendicular to the first plane 311. As shown in fig. 4, before the vacuum switching tube 1 is placed on the rotating mechanism 33, the rotating mechanism 33 may be moved away from the vertical adjustment mechanism 34; as shown in fig. 5, after the operation of placing the vacuum interrupter 1 is completed, the rotating mechanism 33 may be moved to the vicinity of the vertical adjustment mechanism 34 by the slide rail 32.

The clamping mechanism 35 is for clamping the movable contact bar 132 to prevent the movable contact bar 132 from rotating, the clamping mechanism 35 is located on the vertical adjustment mechanism 34, and the clamping mechanism 35 can roll with the linear movement of the movable contact bar 132. The vertical adjustment mechanism 34 can move the clamping mechanism 35 up and down in a direction perpendicular to the first plane 311, so that the clamping mechanism 35 can be adjusted to a proper position to clamp the movable contact bar 132. The movable contact rod 132 can rotate along the axis thereof, and the movable contact rod 132 cannot rotate after being clamped by the clamping mechanism 35, so that damage to other components inside the vacuum switch tube 11 caused by the rotation of the movable contact rod 132 can be avoided. If during the process of mounting or dismounting the adapter 2. The movable contact rod 132 moves linearly in a direction perpendicular to the first plane 311, and the clamping mechanism 35 can roll, so that it can prevent the movable contact rod 132 from rotating, and can cooperate with the removal and installation of the adapter 2 without obstructing the up-and-down movement of the movable contact rod 132.

To facilitate clamping the moving contact bar 132, the moving contact bar 132 has two symmetrical cutouts 1322 at an end remote from the stationary contact, and the clamping mechanism 35 is used to clamp the cutouts 1322. As shown in fig. 2, the adapter 2 has two symmetrical hollow portions 213 on the side surface, and the movable contact rod 132 is clamped by the clamping mechanism 35 through the hollow portions 213. Specifically, each of the hollow portions 213 corresponds to a notch 1322, and the clamping mechanism 35 clamps the notch 1322 of the movable contact rod 132 through the hollow portion 213, so as to avoid slipping.

According to the tool for the vacuum switch tube in the embodiment, the rotating mechanism 33, the vertical adjusting mechanism 34 and the clamping mechanism 35 are matched with each other, so that the movable contact rod 132 can not rotate and can move linearly in the process of mounting or dismounting the adapter 2, further, other parts in the vacuum switch tube 1 can be prevented from being damaged, and the quality of the vacuum switch tube 1 is ensured as much as possible.

Example two

This embodiment will further complement the tool for a vacuum interrupter of the previous embodiment.

As an exemplary illustration, as shown in fig. 3-6, the clamping mechanism 35 includes two juxtaposed clamping assemblies, each clamping assembly including a clamping pin 351, a first bearing 352, a second bearing 353, and a rear cover assembly 354. Wherein the axis of the clamping pin 351 is parallel to the first plane 311 and extends in a first direction L1, the clamping pin 351 being rotatable along the axis; the first bearing 352 is sleeved outside the clamping pin 351, and a first groove is formed in one side, facing the rotating mechanism 33, of the vertical adjusting mechanism 34, and the first bearing 352 is located in the first groove; the second bearing 353 is sleeved on the outer side of the clamping pin 351, a second groove is formed in one side, away from the rotating mechanism 33, of the vertical adjusting mechanism 34, and the second bearing 353 is located in the second groove; the back cover assembly 354 is located on the side of the vertical adjustment mechanism 34 away from the rotational mechanism 33, and the back cover assembly 354 is secured to the second bearing 353 and the clamp pin 351. The first bearing 352 and the second bearing 353 may particularly be ball bearings, for example deep groove ball bearings. Two bearing sleeves are arranged on the clamping pin 351, so that the position of the clamping pin 351 can be fixed, and the shaking of the clamping pin is avoided. The back cover assembly 354 prevents the clamp pin 351 from being largely displaced in the axial direction thereof, as can be seen from fig. 3 to 6, in order to prevent the clamp pin 351 from coming off the second bearing 353.

In order to fix the position of the first bearing 352 relatively, the clamping pin 351 may have a protrusion 3511, the first bearing 352 is located on a side of the protrusion 3511 facing the first groove, and the protrusion 3511 and the first groove cooperate with each other to prevent the first bearing 352 from falling off the clamping pin 351. As can be seen in fig. 6, the protrusion 3511 and the first groove act as a limit for the first bearing 352.

As an exemplary illustration, the rear cover assembly 354 includes a cover 3541, a first gasket 3542, and a retaining pin 3543. The cover 3541 has a through hole, and the first gasket 3542 is disposed on the clamping pin 351. The fixing pin 3543 sequentially passes through the through hole of the cover 3541, the first washer 3542, and the second bearing 353, and extends into the clamp pin 351, for example, is screwed into the clamp pin 351, so that the positions of the cover 3541, the first washer 3542, the second bearing 353, and the clamp pin 351 are fixed to each other. There are of course many ways to fix the position of the clamping pin 351 and the second bearing 353 relative to each other, and will not be described in detail here. The above-mentioned components can be fixed by screws or bolts.

The first bearing 352 and the second bearing 353 rotate in one circle at the inner side, and the other circle at the outer side is fixed, so that the rotating circle is as smooth as possible, and no assembly pre-tightening force is left between the inner circle and the outer circle of the first bearing 352 and the second bearing 353. That is, the first bearing 352 and the second bearing 353 have a clearance in the direction of the axis thereof from the vertical adjustment mechanism 34 so that the fitting preload is held in the inner race, and it is shown in fig. 7 that the first bearing 352 has a clearance X in the direction of the axis thereof from the first groove. The clearance corresponding to the first bearing 352 and the clearance corresponding to the second bearing 353 can be different, for example, the clearance corresponding to the first bearing 352 is 0.5mm-0.8mm, and the clearance corresponding to the second bearing 353 is 0.02mm-0.05 mm. As an exemplary illustration, each clamping assembly further includes a sleeve 355, the sleeve 355 is sleeved outside the clamping pin 351, and two ends of the sleeve 355 respectively abut against the first bearing 352 and the second bearing 353. Due to the presence of the sleeve 355, clearances in the axial direction of the first and second bearings 352 and 353, respectively, with the first and second grooves can be provided. This enables the rotation of the bearings to be smoother.

Alternatively, the spacing between the two clamping pins 351 may be adjustable, which allows for different gauge movable contact bars. For example, through holes of different pitches may be provided on the vertical adjustment mechanism 34, into which the clamp pin 351 may be inserted to adjust the pitch. The distance between the two clamping pins 351 can also be adjusted by the sliding rail 32, which is not described in detail herein.

Optionally, the vertical adjustment mechanism 34 includes a support bracket, a moving portion 341, a cross plate 342, a second screw 343, and a knurled nut 344. The moving portion 341 is connected to the supporting frame, the moving portion 341 has two through holes 3411 in a first direction L1, each clamping component is inserted into one of the through holes 3411, and the moving portion 341 has one threaded hole 3412 in a direction perpendicular to the first plane 311; the transverse plate 342 is fixed on the support frame; the second screw 343 is inserted into the threaded hole 3412; the knurled nut 344 is fixed at one end of the second screw 343, the horizontal plate 342 is located between the moving portion 341 and the knurled nut 344, and the nut can drive the moving portion 341 to move on the supporting frame along a direction perpendicular to the first plane 311. When the knurled nut 344 is rotated, the second screw 343 can move the moving portion 341 up and down, and the position of the clamping mechanism 35 in the direction perpendicular to the first plane 311 can be adjusted. As shown in fig. 3, the center lines of the first and second grooves may be located on the same axis, i.e., the axis of the clamp pin 351, which is parallel to L1, i.e., the first and second grooves are provided at both ends of the through hole 3411, respectively. The above-mentioned components can be fixed by screws or bolts.

Optionally, the supporting frame has two supporting posts 345, the supporting posts 345 are perpendicular to the first plane 311, the two supporting posts 345 are disposed through the moving portion 341, at least one of the supporting posts 345 is fixed with a first stopping portion 346, and the first stopping portion 346 is used for limiting a moving distance of the moving portion 341. As shown, the first stopping portion 346 is located on one of the pillars 345, so as to prevent the moving portion 341 from falling.

Optionally, the vertical adjustment mechanism 34 further comprises a spherical washer 347, the spherical washer 347 disposed through the second screw 343 and between the cross plate 342 and the knurled nut 344. Due to the tolerance of the second screw 343, it is not perfectly perpendicular to the first plane 311, i.e. there is a certain deviation, so that during the rotation of the knurled nut 344, there may be a case of high stress, and the presence of the spherical washer 347 can eliminate the resistance to a certain extent.

As an exemplary illustration, the rotating mechanism 33 includes a base 331, a slewing bearing 332, and a carrier 333. Wherein, the chassis 331 is disposed on the slide rail 32; slewing bearing 332 is fixed to chassis 331; the bearing plate 333 is fixed to the slewing bearing 332, and the bearing plate 333 is used for bearing the vacuum switching tube 1.
