[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] like Figures 1-6 The image shows an embodiment of the replacement device for the sprite contact of a small current switch trolley according to the present invention.
[0022] The replacement device for the plum blossom contact of the small current switch trolley in this embodiment includes: a main shell 1, which is a hollow structure with a accommodating cavity in the middle. The main shell 1 includes a top shell 13 and a supporting outer shell 16 connected to the top shell 13.
[0023] The expansion assembly 18 connected to the expansion housing 16 includes: multiple connectors 181, multiple sleeves 182 connected to the multiple connectors 181 in a one-to-one correspondence, multiple return springs 183 sleeved to the multiple sleeves 182 in a one-to-one correspondence, multiple expansion plates 184 connected to the multiple return springs 183 in a one-to-one correspondence, multiple guide plates 185 connected to the multiple expansion plates 184 in a one-to-one correspondence, and multiple linkage rods 186 connected to the multiple guide plates 185 in a one-to-one correspondence.
[0024] The linkage assembly 2, installed in the top shell 13, is used to open the sprite contact by the linkage support assembly 18; the impact assembly 3, connected to the top shell 13, is used to assist in the assembly of the sprite contact. The linkage assembly is connected to multiple linkage rods 186 respectively. The linkage assembly 2 opens multiple support plates 184 through multiple linkage rods 186 and multiple guide plates 185. The multiple support plates 184 open the ends of the sprite contact that are attached to their outer surface.
[0025] In practice, the linkage component 2 is installed inside the main shell 1, the impact component 3 is installed on the side of the main shell 1, the top shell 13 has a handle 11 on its side, the handle 11 has a baffle 12 on its side, and the top shell 13 has a slot 15 on its side for accommodating the clamping component 27. The bottom surface of the supporting shell 16 has a guide groove 17, and the supporting component 18 is provided inside the side of the supporting shell 16.
[0026] Furthermore, the spreading assembly 18 also includes multiple movable wheels 187 that are connected one-to-one with the multiple linkage rods 186; the linkage assembly 2 includes a linkage plate 22, on which the multiple movable wheels 187 respectively abut against. Specifically, when the multiple movable wheels 187 roll along the linkage plate 22 and lose support, the return spring 183, in conjunction with the multiple spreading plates 184, retracts and resets, removing the perforated contact.
[0027] Preferably, the linkage assembly 2 further includes: a rotating rod 21 connected to one side of the linkage plate 22, a limiting shaft 23 connected to the opposite side of the linkage plate 22, a limiting rod 24 connected to the opposite side of the linkage plate 22, and a handle 26 connected to the end of the rotating rod 21.
[0028] The rotating rod 21 is rotatably installed inside the top shell 13, and its top end is connected to the support frame 14 on the end side of the top shell 13; the bottom of the open outer shell 16 is provided with a guide groove 17, the limiting rod 24 is installed in the guide groove 17, and the limiting shaft 23 is connected to the open outer shell 16.
[0029] Preferably, the end face of the linkage plate 22 is equipped with an anti-slip pad 25.
[0030] During implementation, the entire device is held by the handle 11, with one end of the guide groove 17 of the main housing 1 placed inside the plum blossom contact. The linkage component 2 causes the moving wheel 187 to slide along the surface of the linkage plate 22, which in turn causes the expansion plate 184 to unfold. At this point, one end of the plum blossom contact on the outer surface of the expansion plate 184 is opened, causing the entire plum blossom contact to unfold into a frustum shape. Once the plum blossom contact is installed, rotating the linkage component 2 causes the moving wheel 187 to lose its support. Under the pull of the return spring 183, the expansion plate 184 returns to its retracted state, allowing the device to be quickly removed.
[0031] The principle by which the moving wheel 187 slides along the surface of the linkage plate 22 using the linkage assembly 2 is as follows: Rotating the handle 26 causes the rotating rod 21 to rotate, and the linkage plate 22 on the bottom of the rotating rod 21 also rotates accordingly. Due to the special shape of the linkage plate 22, the rotation presses against the moving wheel 187, causing it to roll along the side of the linkage plate 22, thus unfolding the four-way expansion plates 184. The function of the limiting shaft 23 is to limit the position of the linkage plate 22, making its rotation more stable. Since the limiting rod 24 slides inside the guide groove 17, it limits the rotation angle and direction of the linkage plate 22.
[0032] Furthermore, the linkage component 2 also includes a clamping component 27 for clamping the outer surface of the plum blossom contact.
[0033] The clamping assembly 27 includes: two support seats 275 respectively fastened to opposite sides of the top shell 13, two fixing buckles 271 respectively movably connected to the rotating rod 21, two transmission rods 272 corresponding to the two fixing buckles 271, two connecting buckles 273 corresponding to the two transmission rods 272, and two clamping arms 274. The opposite ends of the two clamping arms 274, the two connecting buckles 273 and the two support seats 275 are correspondingly connected. The rotating rod 21 rotates, causing the fixing buckles 271 to change orientation, pressing the transmission rods 272 to move to one side, so that the top surface of the clamping arm 274 is pushed.
[0034] Preferably, the end of the clamping arm 274 is provided with a clamping plate 276, and a rubber pad 277 is fixedly connected to the side of the clamping plate 276.
[0035] In practice, as the rotating rod 21 rotates, it drives the clamping assembly 27 to move, which clamps and fixes the outer surface of the pendant contact, improving stability during replacement. Specifically, the rotation of the rotating rod 21 causes the two fixing buckles 271 to change orientation, pressing the two transmission rods 272 to move to one side, so that the top surface of the clamping arm 274 is pushed, thereby driving the clamping plate 276 to clamp the pendant contact.
[0036] Furthermore, the impact assembly 3 includes: a side shell 31, a spring rod 32, a slider 33, and an impact soft head 37. The spring rod 32, the slider 33, and the impact soft head 37 are connected in sequence. The spring rod 32 drives the slider 33 to slide inside the side shell 31, and the slider 33, in conjunction with the impact soft head 37, impacts the side of the plum blossom contact.
[0037] Preferably, the impact assembly 3 further includes: a limiting member 35 mounted on the side shell 31, a toggle rod 34 movably connected in the limiting member 35, and a locking rod 36 mounted in the limiting member 35. The locking rod 36 and the toggle rod 34 are detachably connected, and the toggle rod 34 is connected to the slider 33.
[0038] In this embodiment, the slider 33 is movably connected to the inside of the side shell 31, and the side of the side shell 31 is fixedly connected to the toggle rod 34. The top of the outer surface of the toggle rod 34 is movably connected to the limiting member 35, which is fixedly connected to the top of the side of the side shell 31. The top surface of the limiting member 35 is engaged with the locking rod 36, and the bottom of the outer surface of the locking rod 36 is engaged with the inside of the side of the toggle rod 34. The bottom surface of the slider 33 is fixedly connected to the impact soft head 37.
[0039] During implementation, the spring rod 32 drives the slider 33 to slide inside the side shell 31. After the sprite contact is installed, the locking rod 36 can be pulled out. At this time, under the pushing action of the spring rod 32, the slider 33 drives the impact soft head 37 to impact the side of the sprite contact, preventing the sprite contact from being installed in the correct position and affecting normal use. After use, the slider 33 can be moved to retract the spring rod 32, and the moving rod 34 can be inserted into the limiting member 35 and fixed by the locking rod 36 for reuse.
[0040] In this embodiment, the replacement device for the plum blossom contact of the small current switch trolley is implemented by holding the entire device with the handle 11, placing one end of the guide groove 17 of the main shell 1 inside the plum blossom contact, and causing the moving wheel 187 to slide along the surface of the linkage plate 22 through the action of the linkage component 2. The moving wheel 187 drives the expansion plate 184 to unfold, at which time one end of the plum blossom contact on the outer surface of the expansion plate 184 is expanded, so that the entire plum blossom contact is expanded into a frustum shape, which is convenient for disassembly and installation.
[0041] As the rotating rod 21 rotates, it drives the clamping assembly 27 to move, clamping and fixing the outer surface of the pendant contact, improving stability during replacement. Specifically, the rotation of the rotating rod 21 causes the two fixing buckles 271 to change orientation, pressing the two transmission rods 272 to move to one side, so that the top surface of the clamping arm 274 is pushed, thereby driving the clamping plate 276 to clamp the pendant contact.
[0042] It is understandable that once the plum blossom contact is installed, rotating the linkage component 2 causes the moving wheel 187 to lose support. Under the pull of the reset spring 183, the expansion plate 184 returns to the retracted state, allowing the device to be quickly removed.
[0043] The present invention provides a replacement device for the sprite contact of a small current switch trolley, which has the following advantages: The replacement device for the sprite contact of a small current switch trolley includes: a main shell, which includes a top shell and a spreading outer shell; a spreading assembly connected to the spreading outer shell, the spreading assembly including: multiple connectors, multiple sleeves connected to the multiple connectors, multiple return springs sleeved to the multiple sleeves, multiple spreading plates connected to the multiple return springs, multiple guide plates connected to the multiple spreading plates, and multiple linkage rods connected to the multiple guide plates; a linkage assembly installed in the top shell; and an impact assembly connected to the top shell, wherein: the linkage assembly is connected to the multiple linkage rods respectively, and the linkage assembly unfolds the multiple spreading plates through the multiple linkage rods and the multiple guide plates, and the multiple spreading plates spread open the ends of the sprite contacts that are attached to their outer surfaces, enabling quick replacement of the sprite contacts and improving replacement efficiency; the structure is simple and easy to repair and maintain.
