Before explaining the dismounting device provided in the embodiment of the present application, an application scenario related to the embodiment of the present application is explained first.

At present, quick connectors are widely used in the field of electric power. Generally, referring to fig. 1, the quick connector includes a fixing member 01, a restraining sleeve 02, and a plug 03. Wherein, the first end of mounting 01 is used for fixing on the switch board, and plug connector 03 passes through stop collar 02 and connects the second end at mounting 01. For convenience of description, the quick coupling can be understood as a device which can be used for detaching the plug-in connector 03 from the second end of the fixing member 01 only by rotating the limiting sleeve 02 by a first angle along the circumferential direction of the quick coupling and then moving the limiting sleeve 02 by a first distance along the axial direction of the quick coupling. With reference to fig. 1, the stop collar 02 is usually provided with a top ring 021, and the plug 03 is usually provided with a collar 031.

Based on the above description, when the plug-in unit 03 needs to be detached from the second end of the fixing unit 01, a technician can detach the plug-in unit 03 from the second end of the fixing unit 01 only by holding the position-limiting sleeve 02 by a hand and rotating the position-limiting sleeve 02 by a first angle along the circumferential direction of the position-limiting sleeve 02 and then moving the position-limiting sleeve 02 by a first distance along the axial direction, that is, the detachment of the plug-in unit 03 can be completed.

However, in some narrower spaces, when holding the stop collar 02 with a hand to detach the plug-in connector 03, it is very inconvenient, and based on this, the embodiment of the present application provides a detaching device, which can make full use of the above top ring 021 and the collar 031, to detach the plug-in connector 03 from the second end of the fixing member 01 quickly and conveniently.

Next, a detailed explanation will be given of the detaching device provided in the embodiment of the present application.

Referring to fig. 2, fig. 2 shows a schematic structural diagram of a dismounting device in an embodiment of the present application, and an embodiment of the present application provides a dismounting device for dismounting a plug-in connector 03 included in a quick connector in a power distribution cabinet from a fixing member 01, where the dismounting device may include: a handle assembly 1 and a stripper 2. The first end of the dismounting part 2 is fixedly connected with the handle component 1, the second end of the dismounting part is used for being matched with a limiting sleeve 02 which is included by the quick connector, and the limiting sleeve 02 is used for fixing the plug connector 03 on the fixing part 01. When the plug connector 03 needs to be detached, the second end of the detaching part 2 is fixed on the limiting sleeve 02, the handle assembly 1 drives the detaching part 2 to rotate along the axial direction of the limiting sleeve 02, and then the handle assembly 1 drives the detaching part 2 to move to the limiting sleeve 02 along the axial direction of the limiting sleeve 02 so as to detach the plug connector 03 from the fixing part 01.

In this embodiment, when detaching the connector 03 from the fixing member 01, first, the second end of the detaching element 2 can be fixed on the limiting sleeve 02, then, the handle assembly 1 can be rotated along the circumferential direction of the handle assembly 1, the handle assembly 1 can be rotated to drive the detaching element 2 to rotate, and further, the limiting sleeve 02 can be driven to rotate along the circumferential direction of the limiting sleeve 02, after the limiting sleeve 02 rotates by a first angle, the handle assembly 1 can be pushed towards the limiting sleeve 02 along the axial direction of the handle assembly 1, and further, the limiting sleeve 02 can be moved towards the fixing member 01 along the axial direction of the limiting sleeve 02, after the limiting sleeve 02 moves by a first distance, the connector 03 can be detached from the second end of the fixing member 01, that is, the detaching operation of the connector 03 can be completed. It is thus clear that the dismounting device that this application provided need not the manual stop collar of holding of technical staff and carries out the dismantlement work when holding plug connector 03 from the second of mounting 01 to dismantle for it becomes easy to dismantle plug connector 03 in narrow and small space, has also reduced technical staff's intensity of labour simultaneously.

It should be noted that, the first angle and the first distance may be any values, and only the connector 03 needs to be detached from the second end of the fixing member 01, which is not specifically limited in the embodiment of the present application.

In addition, it should be further noted that the above-mentioned stop collar 02 rotates by a first angle along its own circumferential direction, and then moves by the first distance along its own axial direction to detach the plug-in component 03 from the second end of the fixing component 01 is only one possible way of detaching the plug-in component 03 from the second end of the fixing component 01 shown in the embodiment of the present application, and of course, in another possible implementation manner, the stop collar 02 may also move by the first distance along its own axial direction first, and then rotate by the first angle along its own circumferential direction to detach the plug-in component 03 from the second end of the fixing component 01. In other words, the manner of detaching the plug-in unit 03 from the second end of the fixing unit 01 is determined by the structure of the quick connector.

For example, for some quick connectors, if the plug-in connector 03 needs to be detached from the second end of the fixing member 01, the stop collar 02 should be rotated by a first angle along the circumferential direction of the stop collar 02, and then moved by a first distance along the axial direction of the stop collar, so that the plug-in connector 03 can be detached from the second end of the fixing member 01. For other quick connectors, the plug-in connector 03 can be detached from the second end of the fixing member 01 by moving the limiting sleeve 02 along the axial direction of the quick connector for a first distance and then rotating the quick connector for a first angle along the circumferential direction of the quick connector. Therefore, the dismounting device only needs to enable the limiting sleeve 02 to move along the axial direction of the dismounting device and rotate along the circumferential direction of the dismounting device, and as for whether the limiting sleeve 02 moves along the axial direction of the limiting sleeve or rotates along the circumferential direction of the limiting sleeve 02, the dismounting device is not limited in the application, namely, the dismounting mode of the plug-in connector 03 from the second end of the fixing piece 01 is not limited in the embodiment of the application.

It is worth noting that the dismounting object of the dismounting device not only can be a quick connector, but also can be other connectors similar to the dismounting mode of the quick connector, such as an aviation plug, a gas pipe quick connector, an L-shaped quick connector and the like.

In some embodiments, referring to fig. 3, the stripper 2 may comprise: at least one plunger 21. The first end of the insert rod 21 is fixed at the first end of the handle assembly 1, and the second end of the insert rod 21 is used for matching with the stop collar 02. Like this, when need to follow the plug-in components 03 and take off from the second of mounting 01 to hold, can be at first with the second end of inserted bar 21 and stop collar 02 cooperation, make the second end of inserted bar 21 fix on stop collar 02, afterwards, in a possible implementation, can be at first with handle subassembly 1 along the rotatory first angle of the circumferencial direction of self, and then make stop collar 02 along the rotatory first angle of the circumferencial direction of self, next, can again push handle subassembly 1 towards stop collar 02 along the axial direction of handle subassembly 1, make stop collar 02 along the first distance of the axial direction motion of self, at this moment, the plug-in components 03 will be followed the second of mounting 01 and held and taken off.

It should be noted that the first end of the insert rod 21 may be fixed to the first end of the handle assembly 1 by welding, and of course, the first end of the insert rod 21 may also be fixed to the first end of the handle assembly 1 by other manners, for example, the first end of the handle assembly 1 may be fixed by a threaded connection manner or a glue bonding manner, which is not specifically limited in the embodiment of the present application.

In some embodiments, referring to fig. 4, the second end of the insertion rod 21 may be provided with a protrusion 211, the position-limiting sleeve 02 is provided with a top ring 021, the protrusion 211 is matched with the top ring 021 on the position-limiting sleeve 02, and when the plug-in connector 03 needs to be detached, the handle assembly 1 drives the second end of the insertion rod 21 to be inserted into the top ring 021, so that the protrusion 211 abuts against the top ring 021.

Like this, when need with plug-in components 03 from the second end of mounting 01 dismantles, at first can insert the second end of inserted bar 21 in top ring 021, afterwards, in a possible implementation, can at first rotate handle subassembly 1 along the circumferencial direction of self first angle, and then make stop collar 02 rotate first angle along the circumferencial direction of self, next, can push handle subassembly 1 towards stop collar 02 along the axial direction of handle subassembly 1 again, at this moment, because protruding 211 butt is on top ring 021, consequently, under the interact of protruding 211 and top ring 021, will make stop collar 02 along the axial direction of self move, after stop collar 02 moves first distance along the axial direction of self, plug-in components 03 will can follow the second end of mounting 01 and dismantle. That is, the object of detaching the plug-in unit 03 from the second end of the fixing unit 01 is achieved.

It should be noted that the number of the insert rods 21 may be 1, 2 or other numbers, and only the position limiting sleeve 02 needs to be capable of rotating along the circumferential direction of itself and moving along the axial direction of itself, and the number of the insert rods 21 is not specifically limited in the embodiment of the present application.

It should be noted that the protrusions 211 and the top rings 021 may correspond to each other one by one. Therefore, when the number of the top rings 021 is 2, the number of the protrusions 211 can also be 2, and only the protrusions 211 and the top rings 021 need to be ensured to be in one-to-one correspondence, and the number of the protrusions 211 and the top rings 021 is not specifically limited in the embodiment of the present application.

In some embodiments, referring to fig. 4, the plunger 21 may be in a zigzag configuration. As can be seen from the above description, the first end of the insertion rod 21 is fixed to the first end of the handle assembly 1, and the second end of the insertion rod 21 is inserted into the top ring 021, so when the insertion rod 21 is in the zigzag structure, it becomes easier to rotate the position-limiting sleeve 02 by rotating the handle assembly 1 based on the lever principle, and thus the labor intensity of the technician is further reduced.

Next, the present embodiment will explain the handle assembly 1 in detail.

In some embodiments, referring to fig. 4, the handle assembly 1 may include: a handle 11 and a connector 12. A first end of the coupling head 12 is connected to the handle 11 and a second end of the coupling head 12 is connected to the first end of the dismounting member 2.

Wherein, the first end of connector 12 can be through welded mode and handle 11 undetachable connection, certainly, the convenience when taking into account when accomodating dismounting device, in some embodiments, the first end of connector 12 can be dismantled with handle 11 and be connected, for example through threaded connection etc. like this, when needs take in a less space with dismounting device, can dismantle handle 11 from the first end of connector 12, like this, more be favorable to accomodating.

In addition, the second end of the connecting head 12 may be connected to the first end of the detaching element 2 by welding, and of course, the second end of the connecting head 12 may also be connected to the first end of the detaching element 2 by other methods, which is not specifically limited in the embodiment of the present application.

It should be noted that the connector 12 may be made of an insulating material, so that when the dismounting member 2 is charged, the handle 11 may not be charged by the connector 12, thereby reducing the possibility of electric shock to a technician.

In some embodiments, referring to fig. 4, the handle assembly 1 may further comprise: an adaptor 14. A first end of the adapter 14 is connected to a second end of the connector 12 and a second end of the adapter 14 is connected to a first end of the dismounting member 2. In this way, it is possible to fix the first end of the dismounting member 2 directly to the second end of the adapter member 14, avoiding the situation of fixing the first end of the dismounting member 2 directly to the second end of the connecting head 12. Thus, when the joint between the first end of the dismounting member 2 and the second end of the adapter member 14 is broken, the adapter member 14 can be directly replaced, so that the situation that the connector 12 needs to be replaced is avoided, and generally, the economic cost of the connector 12 is higher than that of the adapter member 14, so that the economic cost can be saved.

Further, in some embodiments, referring to fig. 5, the handle assembly 1 may further include an insulating sleeve 13, wherein the insulating sleeve 13 is disposed on the handle 11. Therefore, the occurrence of electric shock of technicians can be further avoided. The insulating sleeve 13 may be made of rubber, plastic, or the like, and of course, the insulating sleeve 13 may also be made of other insulating materials, and only the occurrence of the electric shock of the technician needs to be avoided, and the embodiment of the present application does not specifically limit the material of the insulating sleeve 13.

In some embodiments, referring to fig. 5, the insulating sleeve 13 may be provided with a holding portion 131. In this way, a technician can directly hold the grip 131 with his hand, so that the process of detaching the plug-in unit 03 from the second end of the fixing unit 01 becomes more comfortable.

In some embodiments, referring to fig. 5, the detaching device may further include: the first end of the connecting plate 3 is hinged to the connector 12, and the second end of the connecting plate 3 is used for matching with a sleeve ring 031 on the connector 03. When the handle 11 moves towards the stop collar 02 along the axial direction of the stop collar 02, the connecting plate 3 can drive the plug-in connector 03 to move along the direction far away from the stop collar 02.

When the dismounting device still includes even board 3, in a possible implementation, after handle 11 drives stop collar 02 and rotates first angle along the circumferencial direction of self, can peg graft even board 3 in lantern ring 031, afterwards, can promote handle 11 towards the direction of stop collar 02 along handle 11's axial, make stop collar 02 along the first distance of axial motion of self, at this moment, even board 3 will be along keeping away from direction "perk" of stop collar 02, and then drive plug connector 03 along keeping away from the direction motion of stop collar 02, at this moment, plug connector 03 will end from the second of mounting 01 under even board 3 and dismantle the automation. Thus, the situation that a technician needs to manually hold the plug-in unit 03 and then detach the plug-in unit 03 from the second end of the fixing unit 01 is avoided.

It is worth noting that when the dismounting device further comprises the connecting plate 3, the connecting plate 3 should be inserted into the sleeve ring 031 only after the handle 11 drives the position limiting sleeve 02 to rotate by a first angle along the circumferential direction of the handle, so that the connecting plate 3 is prevented from being inserted into the sleeve ring 031 before the position limiting sleeve 02 rotates by the first angle, and the situation that the rotation work cannot be performed occurs.

In some embodiments, a first end of the link plate 3 may be hinged to the coupling head 12, and a second end of the link plate 3 is adapted to be inserted into the collar 031. Thus, when the handle 11 is pushed in the direction toward the stop collar 02 along the axial direction of the handle 11, the connecting plate 3 will "tilt up" in the direction away from the stop collar 02 under the action of the hinge, so that the plug-in connector 03 can be automatically detached from the second end of the fixing member 01. Of course, the first end of the connecting plate 3 may be hinged to the connecting head 12 by other elements, which are not specifically limited in the embodiment of the present application.

In the embodiment of the application, when dismantling plug connector 03 from mounting 01, at first can fix the second end of dismounting member 2 on stop collar 02, then, can rotate handle assembly 1 along the circumferencial direction of handle assembly 1, handle assembly 1 is rotatory to drive dismounting member 2 rotatory, and then drive stop collar 02 rotatory along the circumferencial direction of self, treat after the rotatory first angle of stop collar 02, can promote handle assembly 1 towards stop collar 02 along the axial direction of handle assembly 1, and then make stop collar 02 move towards mounting 01 along the axial direction of self, treat after stop collar 02 moves the first distance, alright dismantle plug connector 03 from the second end of mounting 01, that is, can accomplish the dismantlement work to plug connector 03. It is thus clear that the dismounting device that this application provided need not the manual stop collar of holding of technical staff and carries out the dismantlement work when holding plug connector 03 from the second of mounting 01 to dismantle for it becomes easy to dismantle plug connector 03 in narrow and small space, has also reduced technical staff's intensity of labour simultaneously. In addition, when the dismounting device further comprises the connecting plate 3, when the handle 11 moves towards the limiting sleeve 02 along the axial direction of the limiting sleeve 02, the connecting plate 3 can be tilted along the direction away from the limiting sleeve 02, so that the plug connector can be automatically dismounted from the second end of the fixing piece 01, and the labor intensity of technicians can be further reduced.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
