[0027] Embodiment 1

[0028] Referring to Figures 1 to 3 , this embodiment provides an arc ignition fixing device for facilitating the replacement of the arc ignition rod, including a fixing component 100. The fixing component 100 includes a connecting plate 101 and side plates 102 vertically provided at both ends of the connecting plate 101. A fixed sleeve 103 is provided on one side of the connecting plate 101, and a stopper 104 is provided inside the fixed sleeve 103; an arc ignition member 200, the arc ignition member 200 includes a long rod 201 and a horizontal axis 202 provided at one end of the long rod 201. A clamping umbrella end 203 is provided at the end of the horizontal axis 202. A first inclined ring surface 203a is provided inside the clamping umbrella end 203, and the clamping umbrella end 203 is fixed by the stopper 104.

[0029] The first inclined ring surface 203a is concavely arranged.

[0030] In this embodiment, an arc ignition fixing device for facilitating the replacement of the arc ignition member 200 (arc ignition rod) is disclosed, which is installed on the disconnecting switch for arc ignition work.

[0031] Further, a square groove 103a is arranged along the radial direction on the inner wall of the fixed sleeve 103, the stopper 104 is embedded in the square groove 103a, and a first spring 103b is arranged in the square groove 103a to connect the stopper 104; one end of the stopper 104 is provided with a first inclined surface 104a; it should be noted that the first inclined surface 104a faces the opening of the inner cavity of the fixed sleeve 103.

[0032] Further, a push plate 103c is arranged in the fixed sleeve 103, and the push plate 103c is connected to the bottom of the inner part of the fixed sleeve 103 through a second spring 103d.

[0033] A shoulder 202a is arranged on the horizontal shaft 202, and an exit member 204 is sleeved on the horizontal shaft 202.

[0034] It should be noted that the exit member 204 is of an annular structure, which is sleeved on the horizontal shaft 202. Preferably, the exit member 204 is connected to the shoulder 202a through a spring, so that the exit member 204 keeps close to the shoulder 202a.

[0035] Second inclined annular surfaces 204a and third inclined annular surfaces 204b are respectively arranged on both sides of the exit member 204; the third inclined annular surface 204b is in contact with the first inclined annular surface 203a.

[0036] An arc ignition contact rod 205 is sleeved on the arc ignition member 200.

[0037] Specifically, during the installation process of the arc ignition member 200 into the fixed sleeve 103, the engaging umbrella end 203 is inserted into the inner cavity of the fixed sleeve 103. The engaging umbrella end 203 contacts and presses the first inclined surface 104a, so that the stopper 104 is pushed into the square groove 103a. When the engaging umbrella end 203 passes over the stopper 104, the stopper 104 returns to its position under the action of the first spring 106b, restricting the stopper 104 from moving out.

[0038] During this process, the stopper 104 pushes the push plate 103c and is finally fixed by the extrusion of the second spring 103d.

[0039] The disassembly process is to squeeze the horizontal shaft 202 into the fixed sleeve 103 again until the third inclined annular surface 204b squeezes and passes over the stopper 104. When pulling back, the stopper 104 drives the exit member 204 to move until the third inclined annular surface 204b is in contact with the first inclined annular surface 203a. At this time, when continuing to pull, the second inclined annular surface 204a presses the stopper 104 and makes the stopper 104 be pressed into the square groove 103a. At the same time, the stopper 104 passes over the engaging umbrella end 203, and at this time the horizontal shaft 202 moves out of the fixed sleeve 103.

[0040] It should be noted that the arc striking contact rod 205 is sleeved on the long rod 201, and a limiting structure is provided on the long rod 201, so that the arc striking contact rod 205 can only move along the axial direction of the long rod 201 and cannot rotate relative to it. The long rod 201 can rotate around the fixed sleeve 103.

[0041] The existing isolating switch includes a first main contact provided on a first support rod and a second main contact provided on a second support rod. The fixing assembly 100 is installed on the first support rod. When they are connected, the arc striking contact rod 205 first enters and connects with the second main contact to strike an arc. Continuing to move, the arc striking contact rod 205 moves along the long rod 201 until the first main contact 101a and the second main contact 102a come into contact.

[0042] Furthermore, the fixing assembly 100 includes a connecting plate 101 and side plates 102 fixed to both sides of the end plate. A column groove 105 is formed between the connecting plate 101 and the side plates 102; a strip 106 is provided on the side plate 102.

[0043] It should be noted that a protruding peripheral plate is provided on the first support rod, which is an existing structure and will not be elaborated here. During installation, the fixing assembly 100 is sleeved on the first support rod, so that the first support rod is located in the column groove 105, and the strip 106 is placed on the peripheral plate to prevent the fixing assembly 100 from falling off.

[0044] Furthermore, a pressing plate 107 is provided in the column groove 105. An embedding block 107a is provided at the end of the pressing plate 107, and an embedding groove 102a is provided on the side plate 102. The embedding block 107a is embedded in the embedding groove 102a; a third spring 107b is provided on the side of the pressing plate 107 to connect the connecting plate 101.

[0045] The pressing plate 107 is limited to move only along the length direction of the embedding groove 102a.

[0046] There are two side plates 102. Vertical grooves 102b and circular grooves 102c are provided at corresponding positions on the side plates 102. The circular groove 102c is provided at the end of the vertical groove 102b; guiding grooves 102d are provided on both sides of the vertical groove 102b, and limiting grooves 102e are provided at the bottom of the guiding grooves 102d; taking the right side in the figure as an example, the limiting groove 102e is opened on the right side of the guiding groove 102d, that is, at the bottom of the guiding groove 102d, and the vertical height of the limiting groove 102e is greater than that of the guiding groove 102d.

[0047] Furthermore, a clamping member 108 is provided at the vertical groove 102b. The clamping members 108 are provided in pairs and symmetrically. The clamping member 108 includes a clamping block 108a and limiting blocks 108b provided at both ends of the clamping block 108a; the clamping block 108a is embedded in the guiding groove 102d, and the limiting blocks 108b are embedded in the limiting grooves 102e.

[0048] It should be noted that the clamping member 108 is limited to move left and right as shown in the figure.

[0049] Specifically, the side of the clamping block 108a is connected to the bottom of the limiting groove 102e through the fourth spring 108c; on the other side of the clamping block 108a, there are a first arc groove 108d and a second arc groove 108e.

[0050] It should be noted that under the action of the fourth spring 108c, a part of the clamping block 108a provided with the first arc groove 108d and the second arc groove 108e is in the vertical groove 102b, playing a role in blocking and limiting.

[0051] Furthermore, the side of the clamping block 108a connected to the fourth spring 108c is the right side of 108a shown in the figure.

[0052] The other side of the clamping block 108a where the first arc groove 108d and the second arc groove 108e are located is the left side of the clamping block 108a shown in the figure.

[0053] It should be noted that the present invention further includes a control member 109. The control member 109 includes a circular shaft 109a and a cam 109b provided on the circular shaft 109a. There is a protruding end 109c on the cam 109b; there is a handle 109d on the cam 109b; there is a side groove 109e at the end of the cam 109b, and a fitting shaft 110 is provided in the side groove 109e. There is a fifth spring 109f in the side groove 109e connecting the fitting shaft 110; there is a second inclined surface 110a at the end of the fitting shaft 110.

[0054] It should be noted that under the connection of the fifth spring 109f, the fitting shaft 110 cannot rotate in the side groove 109e. Preferably, the side groove 109e can be set as a square groove, and the fitting shaft 110 can be set as a square rod to avoid relative rotation between the fitting shaft 110 and the side groove 109e; furthermore, the second inclined surface 110a faces Figure 2 the left side in the middle.

[0055] Specifically, during the installation process, first, the fixing assembly 100 is sleeved on the first rack bar, so that the pressing plate 107 contacts one side of the first rack bar. The circular shaft 109a of the control member 109 is placed in the vertical groove 102b, and the handle 109d is at the lower left. At this time, the side of the cam 109b close to the circular shaft 109a contacts the first rack bar downward. Pull the handle 109d downward, so that the circular shaft 109a presses the clamping block 108a, and the clamping block 108a is pushed into the limiting groove 102e. The circular shaft 109a passes over the clamping block 108a and enters the circular groove 102c. At this time, under the action of the fourth spring 108c, the clamping block 108a returns to its position and restricts the circular shaft 109a.

[0056] During this process, the fitting shaft 110 is in a state of being pressed into the side groove 109e.

[0057] Subsequently, turn the handle 109d (turn upward) until the protruding end 109c contacts the first rack bar. During this process, the third spring 107b is compressed, and the entire fixing assembly 100 holds and fixes the first rack bar; at this time, the insertion shaft 110 corresponds to the position of the vertical groove 102b and pops out under the action of the fifth spring 109f and is inserted into the first arc groove 108d.

[0058] At this time, the control member 109 cannot be taken out. Only when the control member 109 is rotated in the opposite direction again to move the insertion shaft 110 out of the first arc groove 108d and at the same time the protruding end 109c does not contact the first rack bar, can the control member 109 be moved upward and removed from the vertical groove 102b.
