Detailed Description

The embodiment of the invention provides a pin remover 1 which is convenient to carry.

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Fig. 1 is a front view of a pin ejector 1 according to an embodiment of the present invention, and fig. 2 is a top view of the pin ejector 1 shown in fig. 1.

As shown in fig. 1 and 2, the pin ejector 1 according to the embodiment of the present invention includes a pin ejector 11, a holder 12, a clamp 13, and a support 14.

Wherein, one end of the fixed seat 12 is fixedly connected with the pin-removing piece 11, and the other end of the fixed seat 12 is fixedly connected with the supporting piece 14. The clamping member 13 and the fixed base 12 are detachably connected. The user can detach the clamping piece 13 and the fixing base 12.

The clamping piece 13 and the supporting piece 14 are used for clamping the moving piece 2, wherein the mounting hole 21 of the moving piece 2 is penetrated by the part of the fixed seat 12 between the clamping piece 13 and the supporting piece 14.

Specifically, because the clamping member 13 is detachably connected to the fixed base 12, the user can detach the clamping member 13 from the fixed base 12, and then, the mounting hole 21 of the movable member 2 is inserted into the fixed base 12. Then, the clamping member 13 and the fixed base 12 are assembled, and the movable member 2 is clamped using the clamping member 13 and the support member 14 to restrict the movement of the movable member 2. As shown in fig. 3, the mounting hole 21 of the movable member 2 is penetrated by the fixing base 12, and the movable member 2 is located between the clamping member 13 and the supporting member 14, so that the movable member 2 is fixed by the fixing member, the clamping member 13 and the supporting member 14. The user can actuate the pin ejector 1 via the movable part 2.

The pin-removing member 11 is adapted to act on the locking pin to remove the locking pin from the insulator 5. In other words, the pin ejector 1 acts on the locking pin through the pin ejector 11 to complete the pin ejection operation.

It should be understood that there are various specific implementations of the movable element 2 according to the embodiment of the present invention, and fig. 4 is a partial structural schematic view of the movable element 2 according to the embodiment of the present invention.

When a user uses the pin ejector 1 of the embodiment of the invention, the user can control the pin ejecting element 11 to eject the locking pin by using the moving element 2. This pin ejector 1 can dismantle the connection because of clamping piece 13 and fixing base 12 to through the dismouting between control clamping piece 13 and the fixing base 12, can conveniently realize the dismouting of moving part 2 on pin ejector 1. Therefore, after the movable piece 2 is detached from the pin ejector 1, the pin ejector 1 occupies a small space, and the pin ejector is convenient for a user to carry. When a user needs to use the pin ejector 1, the movable piece 2 is installed on the pin ejector 1.

In order to make the pin remover 1 of the embodiment of the present invention suitable for the movable members 2 of various specifications and facilitate stable installation of the movable members 2, optionally, the installation position of the clamping member 13 on the fixed seat 12 can be adjusted. At this time, the distance between the clamping member 13 and the supporting member 14 can be adjusted, so that the clamping member 13 and the supporting member 14 can clamp the movable members 2 of various sizes. In addition, by adjusting the installation position of the clamping member 13 on the fixing seat 12, the clamping member 13 and the supporting member 14 can clamp the movable member 2 more firmly, so that the pin remover 1 of the embodiment of the invention is convenient for users to use.

The mounting position of the clamping member 13 on the fixing base 12 can be adjusted, and the specific implementation manner is various, for example, a plurality of clamping positions are provided on the fixing base 12, and the mounting position of the clamping member 13 on the fixing base 12 can be adjusted by setting the clamping member 13 at different clamping positions. Or, a plurality of holes are formed in the fixing base 12, and the clamping member 13 is inserted into different holes, so that the installation position of the clamping member 13 on the fixing base 12 can be adjusted.

In one specific implementation, as shown in fig. 1, the side of the fixed seat 12 is provided with an external thread. The clamping piece 13 is provided with a connecting through hole, the wall of which is provided with an internal thread. The connecting through hole is in threaded connection with the fixed seat 12, and specifically, the inner thread of the connecting through hole is in threaded connection with the outer thread of the fixed seat 12. Therefore, the position of the clamping piece 13 can be changed by rotating the clamping piece 13 relative to the fixed seat 12, and the installation position of the clamping piece 13 on the fixed seat 12 can be conveniently adjusted.

In a specific example, the clamping member 13 is a nut, and the fixing base 12 is a cylinder. The detachable connection of the clamping member 13 and the holder 12 is achieved by rotating the clamping member 13 relative to the holder 12, which facilitates the operation and use of the user.

Optionally, the supporting member 14 is a plate-shaped structure, and one end of the supporting member 14 is fixedly connected to the fixing base 12. In this way, the support 14 can abut against the moving member 2 more sufficiently, so that the support 14 can stably support the moving member 2, facilitating the user to operate the pin remover 1 through the moving member 2.

In a specific implementation, the movable member 2 is a wrench, and the mounting hole 21 is a through hole provided at the rear portion of the wrench. In this way, the use of existing items in conjunction with the pin ejector 1 can be utilized, thereby reducing costs. In addition, the pin remover 1 of the embodiment of the invention can be used for removing the locking pin from the insulator 5, namely, the pin remover 1 of the embodiment of the invention can be used as a power grid operation tool. In a practical use scenario, a worker often needs to carry various tools, such as a wrench and a pin remover 1, when performing operations, such as maintenance, installation, and the like, on a power grid. The spanner is used as the movable piece 2, and the spanner and the pin removing device 1 are matched for use, so that the spanner has multiple purposes, and the number of tools carried by workers is reduced.

There are several specific implementations of the locking pin and the pin stripper 11, two of which are given below.

Example one:

in this example, the locking pin is an R-shaped locking pin 3, and one end of the locking pin is provided with a through hole.

The pin withdrawing piece 11 is in a hook shape, and one end of the pin withdrawing piece 11, which is far away from the fixed seat 12, is used for extending into a through hole of the locking pin.

Specifically, as shown in fig. 1, 2 and 3, the pin-removing member 11 extends from the end edge of the fixed base 12 in a curved manner in the extending direction of the support member 14. Thus, after the pin-removing member 11 is inserted into the through hole of the locking pin, the locking pin can be pulled in the extending direction of the supporting member 14.

For example, the use scenario of the pin ejector 1 for the pin ejecting operation is shown in fig. 5, 6, and 7. The insulator 5 shown in fig. 5 and 6 is a general insulator 5. The insulator 5 shown in fig. 7 is a deep channel insulator 5.

Wherein the locking pin is mounted in the pin hole of the steel cap 6 of the insulator 5. As shown in fig. 5, the pin removing member 11 of the pin remover 1 of this example extends into the through hole of the locking pin, the fixed seat 12 abuts against the steel cap 6 of the insulator 5, and the user only needs to operate the movable member 2 to pull the locking pin shown in fig. 5 to the position shown in fig. 6, thereby realizing the pin removal. Fig. 6 is a state diagram of the general insulator 5 when the pin is locked and released, and fig. 7 is a state diagram of the deep groove insulator 5 when the pin is locked and released. Fig. 8 shows the installation state of the locking pin after the locking pin is withdrawn. The locking pin in fig. 8 is an R-shaped locking pin 3.

Example two:

in this example, the locking pin is a W-shaped locking pin 4, and one end of the locking pin is an abutting end of a bent structure.

The pin-removing member 11 comprises an abutment bar 15, the abutment bar 15 being adapted to abut the abutment end.

Specifically, as shown in fig. 9, 10, 11 and 12, the pin-removing member 11 further includes a connecting rod 16, and the connecting rod 16 has an L-shaped structure.

One end of the connecting rod 16 is fixedly connected with one end of the fixed seat 12, and the other end of the connecting rod 16 is fixedly connected with the abutting rod 15. Due to the arrangement, the pin withdrawing piece 11 can conveniently extend into the cap socket of the steel cap 6 of the insulator 5, the locking pin is arranged in the pin hole of the steel cap 6 of the insulator 5, and the cap socket is communicated with the pin hole. The pin removing piece 11 extends into the cap socket of the steel cap 6 of the insulator 5 and can be abutted against the locking pin, specifically, the abutting end of the locking pin.

In this example, as shown in fig. 11, the extending direction of the abutment lever 15 and the extending direction of the support 14 are perpendicular. Thus, while the abutting ends of the abutting rod 15 and the locking pin have more contact areas, more contact areas exist between the supporting member 14 and the movable member 2, so that the movable member 2 can stably operate the pin remover 1.

For example, fig. 13, 14 and 15 show a usage scenario in which the ejector 1 performs an ejector operation. The insulator 5 shown in fig. 13 and 14 is a general insulator 5, and the insulator 5 shown in fig. 15 is a deep groove insulator 5.

Wherein the locking pin is mounted in the pin hole of the steel cap 6 of the insulator 5. As shown in fig. 13, the pin removing member 11 protrudes into the cap recess of the steel cap 6 of the insulator 5, and the user operates the movable member 2 so that the abutting rod 15 of the pin removing member 11 abuts against the abutting end of the locking pin. The user promotes moving part 2, drives pin withdrawing device 1, and the butt pole 15 of pin withdrawing piece 11 moves back the round pin operation to the lockpin. The locking pin shown in figure 13 is thereby pushed to the position shown in figure 14 to effect pin withdrawal.

Fig. 14 is a state diagram of the general insulator 5 when locking and releasing the pin, and fig. 15 is a state diagram of the deep groove insulator 5 when locking and releasing the pin. Fig. 16 shows the installation state of the locking pin after the locking pin is withdrawn. The locking pin in fig. 16 is a W-shaped locking pin 4.

In summary, the pin ejector 1 according to the embodiment of the present invention includes a pin ejecting member 11, a fixing base 12, a clamping member 13, and a supporting member 14. Wherein, one end of the fixed seat 12 is fixedly connected with the pin-removing piece 11, and the other end of the fixed seat 12 is fixedly connected with the supporting piece 14. The clamping piece 13 is detachably connected with the fixed seat 12; the clamping piece 13 and the supporting piece 14 are used for clamping the moving piece 2, and the mounting hole 21 of the moving piece 2 is penetrated by the part of the fixed seat 12 between the clamping piece 13 and the supporting piece 14. The user can operate the ejector 1 via the moving part 2. The pin-removing member 11 is adapted to act on the locking pin to remove the locking pin from the insulator 5. Thus, the user can control the pin-removing element 11 to remove the locking pin by using the movable element 2. This pin ejector 1 can dismantle because of clamping piece 13 and fixing base 12 and connect to can make things convenient for the dismouting of moving part 2 on pin ejector 1. Therefore, after the movable piece 2 is detached from the pin ejector 1, the pin ejector 1 occupies a small space, and the pin ejector is convenient for a user to carry.
