The support frame is an annular body with multiple contact fingers arranged inside the annular body. Annular grooves are respectively opened on the outer walls at both ends of the annular body, and the tension spring is arranged in the annular grooves.

[0003] The prior art CN213184047U discloses a portable special disassembly and assembly tool for plum blossom contacts, comprising a hollow handle seat, a pushing assembly and a linkage strut assembly; the pushing assembly is rotatably connected to the rear of the handle seat, and the linkage strut assembly is rotatably connected to the front of the handle seat and is used to open the plum blossom contacts; the pushing assembly comprises a handwheel and a screw, the screw horizontally passes through the handle seat and the outer ring sleeve of the middle section of the screw is provided with a thrust bearing, the thrust bearing is fixed inside the handle seat, the front end of the screw extends outward to pass through the handle seat, and the rear end is fixedly connected to the handwheel; the linkage strut assembly comprises a movable seat connected to the front end of the screw passing through the handle seat, and a plurality of front struts and a plurality of rear struts are arranged along the circumference of the screw and staggered front and back, a positioning block is provided on the screw between the movable seat and the end of the handle seat, and the positioning block is pressed against the handle seat.

[0004] When using the above-mentioned disassembly and assembly tool, the operator of the disassembly and assembly tool holds the handle seat with one hand to stabilize the disassembly and assembly tool, and turns the handwheel with the other hand, so that the handwheel drives the screw rod and the screw to rotate, so that the movable seat at the end of the screw rod away from the handwheel slides on the screw rod, thereby driving the front push rod and the rear push rod to open. Therefore, when the disassembly and assembly tool is used manually to remove the plum blossom contact, a great force is required to turn the handwheel to drive the pushing assembly and the linkage support rod assembly to open the push rod to disassemble the plum blossom contact, resulting in reduced disassembly and assembly efficiency of the plum blossom contact. Utility Model Content

[0005] The utility model aims to provide an electric disassembly and assembly device for plum blossom contacts, so as to solve the problem of low disassembly efficiency of the plum blossom contacts and improve the disassembly and assembly efficiency of the plum blossom contacts.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electric disassembly and assembly device of a plum blossom contact, comprising a main shaft, a sleeve and a mounting seat, the main shaft is rotatably connected to the sleeve, the mounting seat is threadedly connected to the main shaft, a plurality of circumferentially distributed push rods are rotatably provided on the sleeve, a support rod is provided between the mounting seat and the push rod, one end of the support rod is rotatably connected to the mounting seat, and the other end is rotatably connected to the push rod, when the main shaft rotates, the mounting seat slides away from the sleeve to drive the support rod to support the plurality of push rods, a driving member is provided on the sleeve for driving the main shaft to rotate using electric energy, and the output end of the driving member is transmission-connected to the main shaft.

[0007] After adopting the above technical scheme, the utility model has the following advantages: when using the disassembly and assembly tool to disassemble and assemble the plum blossom contact, the driving part is started to drive the main shaft to rotate, and the rotation of the main shaft drives the mounting seat to approach or move away from the shaft sleeve, and the support rod retracts or expands the push rod through the sliding of the mounting seat, so that the end of the push rod away from the shaft sleeve can be extended into the interior of the plum blossom contact; after confirming that the push rod has extended into the plum blossom contact, the driving part is started again to drive the mounting seat on the main shaft away from the shaft sleeve so that the support rod expands the push rod, so that the end of the push rod away from the shaft sleeve abuts against the inner wall of the plum blossom contact, and after confirming that the push rod abuts against the inner wall of the plum blossom contact, the support rod is moved away from the plum blossom contact. The plum blossom contact is pulled in the direction of the installed parts to disassemble the plum blossom contact, or the plum blossom contact is spread out and then installed on the corresponding installation parts to install the plum blossom contact; the mounting seat is connected to the main shaft by a threaded connection to ensure the stability between the mounting seat and the main shaft; whether it is the installation or disassembly of the plum blossom contact, the expansion or retraction of the push rod is driven by a driving member that drives the main shaft to rotate using electric energy, thereby reducing the difficulty of manually driving the main shaft to rotate through a hand wheel, thereby improving the disassembly and assembly efficiency of the plum blossom contact, and reducing the difficulty of manually disassembling the plum blossom contact by using a driving member that drives the main shaft to rotate using electric energy.

[0008] Furthermore, the driving member and the shaft sleeve are separately arranged along the axial direction of the main shaft, and the output end of the driving member is plugged into the main shaft so that the output end of the driving member drives the main shaft to rotate.

[0009] By adopting the above-mentioned technical solution, through the separate setting of the driving part and the sleeve, when it is necessary to disassemble and assemble the plum blossom contact, the driving part is taken out, the output end of the driving part is plugged into the main shaft, and then the power supply of the driving part is started, thereby driving the main shaft to rotate; when it is not necessary to disassemble and assemble the plum blossom contact, the output end of the driving part is pulled out from the main shaft, so that the driving part and the disassembly and assembly device are stored separately; in addition, the same driving part can be used on different disassembly and assembly devices of the same model, thereby reducing the cost of purchasing the driving part.

[0010] Furthermore, the housing of the driving member is detachably connected to the shaft sleeve via a connecting member, and the output end of the driving member is detachably connected to the main shaft.

[0011] By adopting the above-mentioned technical solution, the housing of the driving member and the sleeve are detachably installed through a connecting piece, and the driving member and the sleeve are stored together, which reduces the need to find the driving member separately when using the disassembly and assembly device, thereby reducing the possibility of reducing the disassembly and assembly efficiency of the plum blossom contact.

[0012] Furthermore, the connecting member includes a fastening bolt, which passes through the shaft sleeve and is threadedly connected to the housing of the driving member.

[0013] By adopting the above-mentioned technical solution, the fastening bolt passes through the sleeve along the axial direction of the main shaft and is threadedly connected to the outer shell of the driving member, thereby reducing the possibility of disengagement between the outer shell of the driving member and the sleeve, reducing the possibility of loosening between the outer shell of the driving member and the sleeve, and improving the fastening between the outer shell of the driving member and the sleeve.

[0014] Furthermore, the connecting member includes a connecting rod and a positioning pin, one end of the connecting rod is fixed to the outer shell of the driving member, and the other end extends toward the sleeve and is plugged into the sleeve, and the positioning pin is plugged into the sleeve and fixes the connecting rod to the sleeve.

[0015] By adopting the above-mentioned technical solution, the connecting rod on the outer shell of the driving member is inserted into the shaft sleeve, and then the positioning pin is inserted into the shaft sleeve from the outer peripheral wall of the shaft sleeve to fix the connecting rod on the shaft sleeve, so that the disassembly or installation of the outer shell and the shaft sleeve of the driving member is not affected by the push rod or other structures, which facilitates the disassembly and assembly between the outer shell and the shaft sleeve of the driving member.

[0016] Furthermore, there are multiple groups of connecting rods and positioning pins distributed along the circumference of the sleeve.

[0017] By adopting the above-mentioned technical solution, multiple groups of connecting rods and positioning pins distributed along the circumference of the sleeve improve the stability between the housing of the driving member and the sleeve, and reduce the possibility of loosening of the sleeve and the housing of the driving member during use.

[0018] Furthermore, an inner sleeve is provided on the sleeve, a connecting seat is provided on the inner sleeve, and the push rod is rotatably connected to the connecting seat.

[0019] By adopting the above technical solution, the length of the disassembly and assembly device is increased through the inner sleeve on the sleeve and the connecting seat on the inner sleeve, so as to facilitate the disassembly and assembly of the plum blossom contact at a long distance.

[0020] Furthermore, the inner sleeve is provided with a first step groove for plugging with the sleeve, and the inner sleeve is provided with a first cover plate, a second cover plate and a fastener, the first cover plate is arranged between the sleeve and the inner sleeve and abuts against the groove wall of the first step groove, the second cover plate is arranged on an end surface of the inner sleeve away from the sleeve, and the screw passes through the second cover plate, the inner sleeve and the first cover plate in sequence and is threadedly connected to the sleeve.

[0021] According to the above technical solution, when the inner sleeve is installed on the sleeve, the first cover plate is sleeved on the inner sleeve and the first cover plate is abutted against the groove wall of the first step groove, and then the inner sleeve is inserted into the sleeve so that the outer peripheral side wall of the first step groove contacts the inner hole wall of the sleeve. After the second cover plate is placed on the end face of the inner sleeve away from the sleeve, the screw is passed through the second cover plate, the inner sleeve and the first cover plate in sequence and then threadedly connected with the sleeve. The length of the disassembly and assembly device is increased by the inner sleeve, and the inner sleeve is fixed by screws, the first cover plate and the second cover plate, so as to improve the stability of the increased inner sleeve and reduce the possibility of decreased stability after the length is increased. Moreover, when the longer length is not required, the increased inner sleeve can still be disassembled by screws, so as to improve the applicability of the disassembly and assembly device. The first cover plate and the second cover plate are connected in the axial upper limit sleeve of the inner sleeve, so as to reduce the possibility of the ejector rod being separated from the inner sleeve when the plum blossom contact is subjected to force during disassembly and assembly.

[0022] Furthermore, the plurality of push rods include a front push rod and a rear push rod, and the front push rod and the rear push rod are circumferentially staggeredly arranged on the outer side wall of the sleeve.

[0023] By adopting the above-mentioned technical solution, the push rod is set in the form of a front push rod and a rear push rod. When disassembling and assembling the plum blossom contact, the front push rod and the rear push rod respectively act on the two parts of the plum blossom contact, reducing the possibility of the plum blossom contact being separated from the push rod during the disassembly and assembly process. Multiple front push rods and multiple rear push rods are staggered, so that the supporting force of the front push rod and the rear push rod on the plum blossom contact is evenly distributed, reducing the possibility of deformation of the plum blossom contact during the disassembly and assembly process.

[0024] Furthermore, the front push rod and the rear push rod both include a connecting part, a bending part and a disassembly part, the connecting part is rotatably arranged on the sleeve, the bending part is arranged on an end of the connecting part away from the sleeve, the bending part extends toward the axis of the main shaft, the disassembly part is arranged on a side of the bending part away from the connecting part, and the disassembly part is used to abut the inner wall of the plum blossom contact when the plum blossom contact is disassembled.

[0025] By adopting the above-mentioned technical solution, the connecting part is rotatably connected to the mounting seat, and the bending part leads the disassembly part to be biased towards the axis of the main shaft, so that the end of the disassembly part used for disassembling the plum blossom contact is relatively retracted, which is convenient for the disassembly part to extend into the interior of the plum blossom contact when disassembling the plum blossom contact, and facilitates the connection between the disassembly part and the plum blossom contact when disassembling the plum blossom contact, thereby improving the disassembly efficiency of the plum blossom contact.

[0035] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0036] like Figure 1As shown, the utility model provides an electric disassembly and assembly device for plum blossom contacts, comprising a main shaft 1, a sleeve 2 and a mounting seat 3, the main shaft 1 is rotatably connected to the sleeve 2, the mounting seat 3 is threadedly connected to the main shaft 1, a push rod 4 is rotatably provided on the sleeve 2, a support rod 5 is provided between the mounting seat 3 and the push rod 4, one end of the support rod 5 is rotatably connected to the mounting seat 3, and the other end is rotatably connected to the push rod 4, a driving member 6 for driving the main shaft 1 to rotate using electric energy is provided on the sleeve 2, the output end of the driving member 6 is transmission-connected to the main shaft 1, when the driving member 6 is started, the driving member 6 drives the main shaft 1 to rotate, and as the main shaft 1 rotates, the mounting seat 3 on the main shaft 1 approaches or moves away from the sleeve 2, thereby driving the support rod 5 to retract or open the push rod 4.

[0037] When disassembling and assembling the plum blossom contact, Figures 2 to 6 As shown, when the end of the push rod 4 away from the sleeve 2 is more spread out and cannot extend into the interior of the plum blossom contact, the driving member 6 is started to drive the main shaft 1 to rotate, so that the mounting seat 3 slides close to the sleeve 2 on the main shaft 1, so that the end of the push rod 4 away from the sleeve 2 is retracted, which is convenient for the push rod 4 to extend into the inner wall of the plum blossom contact. After the push rod 4 extends into the plum blossom contact, the driving member 6 is started in the reverse direction, so that the mounting seat 3 on the main shaft 1 is away from the sleeve 2, and the support rod 5 supports the push rod 4, further making the push rod 4 abut against the inner wall of the plum blossom contact, and then the plum blossom contact is removed from the mounting component or installed on the mounting component, and the main shaft 1 is driven to rotate by the driving member 6 to drive the mounting seat 3 to slide, thereby reducing the difficulty of driving the main shaft 1 to rotate by manpower, thereby reducing the difficulty of disassembling and assembling the plum blossom contact and improving the disassembly and assembly efficiency of the plum blossom contact.

[0038] Furthermore, in order to facilitate the threaded connection between the mounting seat 3 and the spindle 1, the end of the spindle 1 away from the driving member 6 is a threaded end, and an internal threaded hole is provided on the mounting seat 3. When the mounting seat 3 is threadedly connected to the spindle 1, the internal threaded hole is connected to the threaded end of the spindle 1. The threaded connection between the mounting seat 3 and the spindle 1 improves the stability between the mounting seat 3 and the spindle 1, and reduces the possibility that the mounting seat 3 drives the spindle 1 to rotate in the reverse direction and affects the disassembly and assembly efficiency.

[0039] In one embodiment, the driving member 6 is separately provided between the sleeve 2. When the driving member 6 is required to drive the main shaft 1 to rotate, the output end of the separated driving member 6 is plugged into the main shaft 1, and then the driving member 6 is started, so that the output end of the driving member 6 drives the main shaft 1 to rotate. By using the driving member 6, the difficulty of manually rotating the main shaft 1 is reduced, thereby increasing the difficulty of disassembling and assembling the plum blossom contact. In addition, the driving member 6 is separately provided with the sleeve 2, so that the same driving member 6 can be used on different disassembly and assembly devices of the same model, reducing the number of driving members 6 purchased and further reducing costs.

[0040] In another embodiment, Figure 1As shown, the housing of the driving member 6 is detachably connected to the shaft sleeve 2 via a connecting member 22 , and at the same time, the output end of the driving member 6 is detachably connected to the main shaft 1 .

[0041] Specifically, the connecting member 22 includes a fastening bolt, a threaded hole 61 is provided on the outer shell of the driving member 6, and a fastening through hole 62 coaxial with the threaded hole 61 is provided on the sleeve 2. The fastening bolt passes through the fastening through hole 62 and is threadedly connected in the threaded hole 61, so that the sleeve 2 and the outer shell of the driving member 6 can be detachably installed together, reducing the need to separately find a disassembly and assembly device and the driving member 6 when disassembling and assembling the plum blossom contact; in addition, through the threaded connection between the fastening bolt and the outer shell of the driving member 6, the stability of the installation of the outer shell of the driving member 6 and the sleeve 2 is improved, and the possibility of loosening or even disengagement between the outer shell of the driving member 6 and the sleeve 2 is reduced.

[0042] Regarding the specific structure of the connecting member 22, in another embodiment, as Figure 2 As shown, the connecting member 22 includes a connecting rod 221 and a positioning pin 222. One end of the connecting rod 221 is fixed on the outer shell of the driving member 6, and the other end extends along the axial direction of the main shaft 1 and is plugged into the sleeve 2. The positioning pin 222 extends along the radial direction of the sleeve 2 and is plugged into the sleeve 2. The end of the positioning pin 222 extends into the sleeve 2 and is threadedly connected with the sleeve 2 after passing through the connecting rod 221, thereby fixing the connecting rod 221 and the sleeve 2, reducing the possibility of the sleeve 2 and the driving member 6 loosening or even disengaging during use. When the outer shell and the sleeve 2 of the driving member 6 need to be disassembled, the positioning pin 222 is removed from the outer peripheral side wall of the sleeve 2, and then the outer shell and the sleeve 2 of the driving member 6 are pulled out along the axial direction of the main shaft 1, and the outer shell of the driving member 6 and the sleeve 2 are disassembled and separated. When the positioning pin 222 and the connecting rod 221 are disassembled, they are not affected by other structures on the disassembly device, which facilitates the disassembly of the outer shell of the driving member 6 and the sleeve 2.

[0043] In order to further improve the stability between the outer shell of the driving member 6 and the shaft sleeve 2, multiple groups of connecting rods 221 and positioning pins 222 are distributed along the circumference of the shaft sleeve 2, and the multiple groups of connecting rods 221 and positioning pins 222 are evenly distributed around the circumference. Multiple connecting rods 221 and multiple positioning pins 222 increase the stability between the outer shell of the driving member 6 and the shaft sleeve 2, and reduce the possibility of disengagement between the outer shell of the driving member 6 and the shaft sleeve 2.

[0044] In another embodiment, the housing of the driving member 6 is integrally provided with the shaft sleeve 2. When the plum blossom contact is used, the driving member 6 and the disassembly and assembly device can be directly taken out and used directly, thereby reducing the possibility of assembly or searching before use, thereby improving the disassembly and assembly efficiency of the plum blossom contact.

[0045] In another embodiment, if Figure 3As shown, in order to make the disassembly and assembly device adaptable to different working conditions, one end of the sleeve 2 is connected to an inner sleeve 21, and a connecting seat 215 is provided on the outer peripheral side wall of the inner sleeve 21, and the push rod 4 is rotatably connected to the connecting seat 215. By providing the inner sleeve 21, the total length of the disassembly and assembly device is increased, so that the disassembly and assembly device can disassemble some plum blossom contacts in special positions, thereby improving the utilization rate of the plum blossom contacts.

[0046] Specifically, Figure 3 As shown, the inner sleeve 21 is provided with a first step groove 211 for connecting with the sleeve 2, and the first step groove 211 divides the inner sleeve 21 into a large diameter end and a small diameter end. The inner sleeve 21 is provided with a first cover plate 212, a second cover plate 213 and a screw 214. Specifically, the first cover plate 212 is sleeved on the small diameter end of the inner sleeve 21 and abuts against the large diameter end of the inner sleeve 21, and the second cover plate 213 is arranged on the end surface of the inner sleeve 21 facing away from the sleeve 2. The first cover plate 212 and the second cover plate 213 are connected to the axial upper limit connection seat 215 of the inner sleeve 21 to reduce the possibility of the connection seat 215 being separated from the inner sleeve 21 when the push rod 4 is subjected to force. The screw 214 passes through the second cover plate 213, the inner sleeve 21 and the first cover plate 212 in turn and is threadedly connected to the sleeve 2, thereby increasing the overall length of the disassembly and assembly device, which is convenient for the disassembly and assembly device to be applied to different working conditions. The screw 214 stably mounts the inner sleeve 21 on the sleeve 2, thereby reducing the possibility of the inner sleeve 21 and the sleeve 2 being loosened when the plum blossom contact is disassembled.

[0047] In order to improve the contact effect of the push rod 4 on the inner wall of the plum blossom contact, in another embodiment, as shown in FIG. Figure 2 and Figure 4 As shown, the push rod 4 includes multiple front push rods 41 and multiple rear push rods 42. The multiple front push rods 41 correspond to the multiple rear push rods 42 one by one and are connected to the outer peripheral side wall of the sleeve 2 in an alternating rotation. When disassembling and assembling the plum blossom contact, the front push rods 41 and the rear push rods 42 act on different positions of the plum blossom contact respectively. When the rear push rod 42 is separated from the inner wall of the plum blossom contact, the front push rod 41 is still in contact with the plum blossom contact, and the contact between the rear push rod 42 and the inner wall of the plum blossom contact can be adjusted in time, thereby reducing the possibility of the front push rod 41 and the rear push rod 42 being separated from the plum blossom contact when disassembling and assembling the plum blossom contact.

[0048] Furthermore, the plurality of front push rods 41 and the plurality of rear push rods 42 are evenly distributed around the circumference, so that the front push rods 41 and the rear push rods 42 are evenly abutted against the inner wall of the plum blossom contact around the circumference, thereby reducing the possibility of deformation of the plum blossom contact during disassembly and assembly. Figure 5 As shown, in order to facilitate the expansion of the front push rod 41 and the rear push rod 42 , a plurality of support rods 5 are evenly distributed along the outer peripheral wall of the mounting seat 3 , and each front push rod 41 and each rear push rod 42 corresponds to a support rod 5 .

[0049] Specifically, Figure 2 and Figure 3 As shown, the front push rod 41 and the rear push rod 42 both include a connecting portion 411, a bending portion 413 and a disassembly portion 412. The connecting portion 411 is rotatably connected to the outer peripheral wall of the sleeve 2, one end of the bending portion 413 is connected to the connecting portion 411, and the other end extends toward the axis of the main shaft 1. The disassembly portion 412 is arranged at one end of the bending portion 413 away from the connecting portion 411. The bending portion 413 makes the disassembly portion 412 closer to the axis of the main shaft 1, so that the disassembly portion 412 can enter and exit the interior of the plum blossom contact and abut against the inner wall of the plum blossom contact when disassembling the plum blossom contact.

[0050] Further, such as Figure 3 As shown, a top block 414 is provided on one end of the disassembly part 412 away from the bending part 413, and the top block 414 extends in a direction away from the axis of the main shaft 1. When the disassembly part 412 abuts against the inner wall of the plum blossom contact, the top block 414 abuts against the inner wall of the plum blossom contact, thereby increasing the abutment effect of the disassembly part 412 against the inner wall of the plum blossom contact.

[0051] like Figure 3 As shown, before the disassembly and assembly device extends into the interior of the plum blossom contact, the driving member 6 drives the main shaft 1 to rotate, so that the mounting seat 3 drives the support rod 5 to move toward the driving member 6, thereby making the disassembly and assembly portion 413 close to the center of the main shaft 1, so as to facilitate the disassembly and assembly portion 413 and the top block 414 to extend into the interior of the plum blossom contact. After determining the positions of the disassembly and assembly portion 413 and the top block 414, as shown in FIG. Figure 6 As shown, the driving member 6 is started to drive the main shaft 1 to reverse, so that the mounting seat 3 on the main shaft 1 drives the support rod 5 away from the driving member 6, and the support rod 5 opens the connecting part 411, thereby driving the disassembly part 413 and the top block 414 to abut against the inside of the plum blossom contact.

[0052] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
