[0038] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0039] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] In this embodiment, a pre-installed structure and an isolating switch including the pre-installed structure are proposed; wherein the isolating switch also includes an isolating body and a handle, the pre-installed structure is used to pre-fix the handle to the isolating body, and the operating mechanism in the isolating body can be controlled by twisting the handle, so as to achieve closing or opening. The isolating body and the operating mechanism therein in this embodiment are common structures in existing isolating switches, and the working principles of the isolating body and the operating mechanism are not described in detail here.

[0041] It is worth noting that the isolating switch further includes a fixing member, which is used to fix the handle and the mounting panel in the pre-installed structure after the handle is pre-fixed, so as to ensure the fixing stability between the handle and the mounting panel and make the fixing connection between the handle and the mounting panel simple and convenient. In this embodiment, the fixing member can be a screw.

[0042] Specifically, Figures 1 to 6 As shown, the pre-installed structure includes the above-mentioned mounting panel 30 and sliding member 40; wherein, the mounting panel 30 is fixedly installed to one side of the isolation body 10, and the handle 20 can be inserted into the mounting panel 30 and connected to the operating mechanism in the isolation body 10; the sliding member 40 is slidably arranged in the gap space between the mounting panel 30 and the isolation body 10 along the Z axis, so that the sliding member 40 has an avoidance position and a clamping position; a clamping groove 23 is provided on one of the sliding member 40 and the handle 20, and a clamping protrusion 41 is provided on the other; when the sliding member 40 slides to the avoidance position, the sliding member 40 can avoid the handle 20, so that the handle 20 can be smoothly inserted into the mounting panel 30 and connected to the operating mechanism; when the sliding member 40 slides to the clamping position, the clamping protrusion 41 is clamped into the clamping groove 23, so that the handle 20 can be pre-fixed and connected to the isolation body 10 through the sliding member 40.

[0043] Compared with the prior art, the pre-installed structure in this embodiment changes the fixed connection method between the handle 20 and the mounting panel 30, that is, the handle 20 needs to be pre-fixed before the fixing member is used to fix the handle 20 and the mounting panel 30; when the sliding member 40 slides downward along the Z axis to the avoidance position, the handle 20 can be connected to the mounting panel 30 and connected to the operating mechanism in the isolation body 10, so that the handle 20 controls the operating mechanism to close or open the switch, and at this time, the sliding member 40 will not interfere with the insertion of the handle 20 in the mounting panel 30; when the sliding member 40 slides upward along the Z axis to the clamping position, the clamping protrusion 41 is clamped into the clamping groove 23, so that the sliding member 40 It is fixedly connected to the handle 20 so as to provide front-to-rear direction limitation for the handle 20 through the sliding member 40; since the handle 20 is inserted into the mounting panel 30 at this time so as to provide circumferential direction limitation for the handle 20 through the mounting panel 30, the handle 20 can be pre-fixed to the mounting panel 30 through the limitation of the sliding member 40; on this basis, when the handle 20 and the mounting panel 30 are fixedly connected through the fixing member, it is only necessary to hold the isolation body 10 with one hand; compared with the prior art that directly uses screws to fasten, the pre-fixing operation of the handle 20 is added before the fixing member is fixed, so that the subsequent fixing process only needs one person to complete, reducing labor costs and saving time and effort.

[0044] Furthermore, if Figures 1 to 4 As shown, a sliding groove 12 is provided in the gap space between the isolation body 10 and the mounting panel 30, and the sliding groove 12 extends along the Z axis. The sliding member 40 can move along the Z axis in the sliding groove 12; and the sliding member 40 has elasticity. In this embodiment, a clamping protrusion 41 is provided on the sliding member 40, and a clamping groove 23 is provided on the handle 20. In other embodiments, the clamping groove 23 can also be provided on the sliding member 40, and the clamping protrusion 41 can also be provided on the handle 20.

[0045] Specifically, Figures 3 to 5 As shown, the sliding member 40 is an inverted U-shaped structure, and a clamping protrusion 41 is respectively provided on two opposite sides of the inverted U-shaped structure, and the two clamping protrusions 41 are arranged opposite to each other, and the upper end of the inverted U-shaped structure is wider than the lower end, that is, the entire sliding member 40 is a structure that is wide at the top and narrow at the bottom. In other embodiments, the width of the upper end of the inverted U-shaped structure can also be made consistent with the width of the lower end, as long as the clamping protrusion 41 can be clamped into the clamping slot 23, and no specific limitation is made here.

[0046] By setting the sliding member 40 as a structure that is wide at the top and narrow at the bottom, on the one hand, the lower end of the sliding member 40 can gradually become larger during the process of the sliding member 40 sliding downward along the Z axis, so as to better avoid the insertion of the handle 20 in the mounting panel 30, and the sliding member 40 will produce elastic deformation at this time; on the other hand, the sliding member 40 can automatically rebound to the locking position under the action of its own elastic force during the process of the sliding member 40 sliding upward along the Z axis, and the lower end of the sliding member 40 will automatically retract at this time, so as to be better locked into the locking groove 23, so that the locking effect is more stable. The use of the sliding member 40 can save time and effort and save labor costs by moving the sliding member 40 upward along the Z axis to the locking position.

[0047] Furthermore, if Figure 5 As shown, the latching protrusion 41 is protruded on the side surface of the sliding member 40 toward the inner side of the inverted U-shaped structure, and the top end surface 411 of the latching protrusion 41 is tilted along the lower end of the inverted U-shaped structure; by tilting the top end surface 411 of the latching protrusion 41, it can provide a guiding effect when the sliding member 40 moves upward along the Z-axis to the latching position, so that the latching protrusion 41 can be better latched into the latching groove 23 to ensure smooth latching.

[0048] Specifically, Figures 3 to 5 As shown, a first guide bevel 13 is also provided in the gap space between the isolation body 10 and the mounting panel 30, and a second guide bevel 412 is provided at the bottom end of the sliding member 40. The second guide bevel 412 can slide on the first guide bevel 13, that is, the first guide bevel 13 and the second guide bevel 412 are slidably matched; when the sliding member 40 slides in the sliding groove 12 along the Z axis, the second guide bevel 412 slides along the first guide bevel 13 to provide a guiding effect for the sliding of the sliding member 40, thereby ensuring the guiding and reliability of the sliding of the sliding member 40 on the Z axis.

[0049] Specifically, the pre-installed structure further includes a fastener. When the sliding member 40 is located at the clamping position, in order to ensure the position fixity of the sliding member 40 and prevent the sliding member 40 from moving at will, the fastener fixes the sliding member 40 between the isolation body 10 and the mounting panel 30, so as to ensure that the position of the sliding member 40 does not move at this time, thereby better ensuring the reliability of the sliding member 40 fixing the handle 20 to the mounting panel 30. In this embodiment, the fastener can be a bolt, and the operation process of fixing the sliding member 40 between the isolation body 10 and the mounting panel 30 by bolts only needs one person to complete, and no additional labor cost is added.

[0050] It is worth noting that even if no fastener is provided, the position stability of the sliding member 40 at the engaging position can also be ensured, that is, the sliding member 40 will not automatically move randomly on the Z axis without the action of external force or its own elastic force.

[0051] Furthermore, if Figure 1 and Figure 6 As shown, a mounting hole 31 is provided in the mounting panel 30, a first connecting hollow shaft 11 connected to the operating mechanism is provided in the mounting hole 31, a second connecting hollow shaft 21 is provided on the handle 20, a plug-in shaft 22 is installed in the second connecting hollow shaft 21, the plug-in shaft 22 can be plugged into the first connecting hollow shaft 11, and the second connecting hollow shaft 21 is plugged into the mounting hole 31 and sleeved on the outside of the first connecting hollow shaft 11, and a card groove 23 or a card protrusion 41 is provided on the outside of the second connecting hollow shaft 21.

[0052] In this embodiment, Figures 3 to 5 As shown, two oppositely arranged card grooves 23 are provided on the outside of the second connecting hollow shaft 21. After the second connecting hollow shaft 21 is inserted into the mounting hole 31, the second connecting hollow shaft 21 can be located in the gap space between the isolation body 10 and the mounting panel 30, so that a card protrusion 41 can be engaged with a card groove 23, so as to ensure that the fixed connection between the sliding member 40 and the handle 20 is more stable.

[0053] Furthermore, if Figure 1 As shown, the shape of the mounting hole 31 is non-circular and matches the shape of the second connecting hollow shaft 21, so as to ensure that the second connecting hollow shaft 21 is plugged into the mounting hole 31 at a preset angle, avoiding the problem of reverse installation of the second connecting hollow shaft 21, that is, the non-circular mounting hole 31 can provide a fool-proof effect for the plug-in of the second connecting hollow shaft 21; and the non-circular mounting hole 31 can ensure that the second connecting hollow shaft 21 will not shake in the mounting hole 31, ensuring the limited plug-in of the second connecting hollow shaft 21 in the mounting hole 31.

[0054] The specific working process of the pre-installed structure in this embodiment is as follows:

[0055] When installing and fixing the handle 20, first, push the sliding member 40 into the sliding groove 12 along the Z axis, and then press the sliding member 40 downward along the Z axis to the position as shown in FIG. Figure 3In the avoidance position shown, the latching protrusion 41 on the sliding member 40 will not interfere with the insertion of the handle 20 into the mounting hole 31, so that the second connecting hollow shaft 21 on the handle 20 can be inserted into the mounting hole 31 on the mounting panel 30; at the same time, the plug-in shaft 22 in the second connecting hollow shaft 21 is inserted into the first connecting hollow shaft 11, and the second connecting hollow shaft 21 is sleeved on the outside of the first connecting hollow shaft 11 to realize the connection between the handle 20 and the operating mechanism in the isolation body 10; that is, at this time, the second connecting hollow shaft 21 cannot rotate in the mounting hole 31, and the mounting hole 31 has a certain limiting effect on the handle 20.

[0056] Then, the downward pressure on the sliding member 40 is released, so that the sliding member 40 can automatically rebound upward along the Z axis to a position as shown in FIG. Figure 4 The snap-in position shown, at this time, the snap-in protrusion 41 on the sliding member 40 is snap-into the snap-in groove 23 on the second connecting hollow shaft 21, and the sliding member 40 is fixedly connected between the isolation body 10 and the mounting panel 30 by means of fasteners, so as to achieve a fixed connection between the handle 20 and the sliding member 40; so as to achieve a pre-fixed connection of the handle 20 to the mounting panel 30 by means of the snap-in limit between the sliding member 40 and the handle 20, so that a pre-fixed connection is formed between the handle 20 and the isolation body 10 before being fixedly connected by the fixing member.

[0057] Afterwards, the handle 20 is fixedly connected to the mounting panel 30 using a fixing member; when the handle 20 needs to be disassembled, the fixing member and the fasteners on the sliding member 40 are removed, and then the sliding member 40 is pressed downward along the Z axis to an avoidance position to pull the handle 20 out of the mounting hole 31 in the mounting panel 30.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
