Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a portable installation structure for a transformer core. Background Technology

[0002] The transformer core is the magnetic circuit core of the transformer, typically made of laminated silicon steel sheets with high magnetic permeability. It conducts and concentrates the magnetic field to achieve efficient electromagnetic induction. Its function is to reduce eddy current losses and improve energy transmission efficiency. Core structures are divided into two types: core-type and shell-type, directly affecting the transformer's performance, losses, and size.

[0003] However, the installation of most transformer cores is quite complicated. The installation in the narrow internal space of the transformer is time-consuming and labor-intensive, which reduces the installation efficiency. In addition, the installation structure of some transformer cores lacks auxiliary fixing parts. In extreme outdoor weather, if the bolts at the bottom of the core loosen, the core is very likely to tip over and be damaged, which reduces the practicality of the device.

[0004] Therefore, those skilled in the art have provided a portable installation structure for transformer cores to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a portable installation structure for transformer cores. The device extends the elastic telescopic rod at one end of the sliding frame by pulling a locking plate, causing the locking plate to detach from the sliding frame. Twisting the locking plate causes an angle change between the linkage rod and the elastic telescopic rod, thus creating a sliding opening for the sliding frame. The sliding plate and the core body threaded onto it are then slidably inserted. After being inserted into the sliding frame, the locking plate is pulled and aligned with one end of the sliding frame before being released. The elastic telescopic rod causes the locking plate to spring back and engage with one end of the sliding frame, facilitating the installation of the core body and improving the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A portable installation structure for a transformer core includes a transformer housing, a sealing door, a connecting end, and a core body. A sliding installation mechanism is fixedly connected to the lower end inside the transformer housing, and auxiliary fixing mechanisms are fixedly connected to both ends of the inner wall of the transformer housing.

[0008] The sliding installation mechanism includes a support platform, a sliding frame is threadedly connected to the upper end face of the support platform, a side slot is opened at one end of each side end face of the sliding frame, an elastic telescopic rod is fixedly connected to one end of the outer wall of the side slot, a linkage rod is rotatably connected to one end of the elastic telescopic rod, a locking plate is rotatably connected to one end of the linkage rod, and a sliding plate is slidably connected to one side of the outer wall of the sliding frame.

[0009] Through the above technical solution, the device stretches the elastic telescopic rod at one end of the sliding frame by pulling the locking plate, causing the locking plate to detach from one end of the sliding frame. Twisting the locking plate causes the linkage rod and the elastic telescopic rod to change angle, thereby reserving a sliding opening for the sliding frame. Then, the sliding plate and the iron core body connected to it are slidably inserted. After being inserted into the sliding frame, the locking plate is pulled and aligned with one end of the sliding frame and then released. The elasticity of the elastic telescopic rod causes the locking plate to spring back and engage with one end of the sliding frame, which facilitates the installation of the iron core body and improves the practicality of the device.

[0010] Furthermore, the auxiliary fixing mechanism includes a telescopic baffle, one end of which is fixedly connected to a pin, a connecting part is fixedly connected to one side of the inner wall of the transformer housing, a knob is rotatably connected to the middle of one side end face of the connecting part, a connecting rod is fixedly connected to one side of the outer wall of the knob, a retaining ring is fixedly connected to one end of the connecting rod, a sliding groove is provided in the middle of one side end face of the connecting part, a spring is fixedly connected to one end of the outer wall of the sliding groove, a locking block is fixedly connected to one end of the spring, and an insertion interface is provided at the lower end of one side end face of the connecting part.

[0011] Through the above technical solution, the device extends the telescopic baffle by pulling open one end, and then inserts the pin at one end of the telescopic baffle into the insertion interface on the connecting part. After insertion, the knob is turned, which drives the connecting rod and the retaining ring to rotate at a certain angle and pass through the insertion interface to form a locking connection with the pin. At the same time, the retaining ring moves away from the spring, pushing the retaining block to pop out from the slide groove and blocking the connecting rod to prevent the retaining ring from reversing. This achieves auxiliary fixation of the upper end of the iron core body and improves the practicality of the device.

[0012] Furthermore, a sealing door is rotatably connected to the middle of one end face of the transformer housing, and multiple connecting ends are provided on the upper end face of the transformer housing. The upper end of the sliding plate is threadedly connected to the iron core body.

[0013] Through the above technical solution, the tight fit between the sealing door and the card plate can play an auxiliary role in preventing loosening, the connection end is used for the normal working connection of the transformer, and the sliding plate supports the iron core body to slide into the sliding frame for convenient installation.

[0014] Furthermore, one end of the elastic telescopic rod is slidably connected to one side of the outer wall of the side slot, and one end of the clamping plate is engaged with one end of the sliding frame;

[0015] Through the above technical solution, the elastic telescopic rod can extend normally and give full play to its elastic advantages, and the card plate can use its elasticity to fix one end of the sliding frame.

[0016] Furthermore, a slot is provided on one side of the inner wall of the transformer housing, and one side of the outer wall of the slot is engaged with one end of the telescopic baffle.

[0017] The above technical solution allows the slot to be used for placement during the auxiliary fixing stage of the telescopic baffle, thus avoiding obstruction of the installation of the iron core body.

[0018] Furthermore, one side of the outer wall of the groove forms a sliding connection with one end face of the locking block;

[0019] Through the above technical solution, the spring can use its elasticity to make the locking block pop out of the slide and be restricted by the outer wall of the slide. Therefore, the locking block blocks the rotation path of the connecting rod at one end of the locking ring, thereby fixing the pin and the telescopic baffle at one end.

[0020] Furthermore, one end of the retaining ring passes through one end of one side face of the insertion interface and forms a snap-fit ​​connection with one end of the pin;

[0021] Through the above technical solution, the pin can be positioned by the depth of the insertion interface and the snap-fit ​​point of the retaining ring.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a portable installation structure for transformer cores. The device extends the elastic telescopic rod at one end of the sliding frame by pulling the locking plate, causing the locking plate to detach from one end of the sliding frame. Twisting the locking plate causes the linkage rod and the elastic telescopic rod to change angle, thereby reserving a sliding opening for the sliding frame. Then, the sliding plate and the core body connected to it by threads are slidably inserted. After being inserted into the sliding frame, the locking plate is pulled and aligned with one end of the sliding frame and then released. The elastic telescopic rod causes the locking plate to spring back and engage with one end of the sliding frame, which facilitates the installation of the core body and improves the practicality of the device.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-3 This utility model provides a specific implementation method:

[0035] A portable installation structure for a transformer core includes a transformer housing 1, a sealing door 2, a connecting end 3, and a core body 5. A sliding installation mechanism 4 is fixedly connected to the lower end of the transformer housing 1, and auxiliary fixing mechanisms 6 are fixedly connected to both ends of the inner wall of the transformer housing 1. The sliding installation mechanism 4 includes a support platform 41, with a sliding frame 42 threadedly connected to the upper end face of the support platform 41. Side slots 43 are provided at one end of each side face of the sliding frame 42. An elastic telescopic rod 44 is fixedly connected to one end of the outer wall of the side slot 43. A linkage rod 45 is rotatably connected to one end of the elastic telescopic rod 44, and a locking plate 46 is rotatably connected to one end of the linkage rod 45. The outer wall of the sliding frame 42... A sliding plate 47 is slidably connected to one side of the device. By pulling the locking plate 46, the elastic telescopic rod 44 at one end of the sliding frame 42 is stretched, and the locking plate 46 is disengaged from one end of the sliding frame 42. Twisting the locking plate 46 causes the linkage rod 45 and the elastic telescopic rod 44 to change angle, thereby reserving a sliding opening for the sliding frame 42. Then, the sliding plate 47 and the iron core body 5 threaded on it are slidably inserted. After the sliding frame 42 is inserted into place, the locking plate 46 is pulled and aligned with one end of the sliding frame 42 and then released. The elasticity of the elastic telescopic rod 44 causes the locking plate 46 to spring back and engage with one end of the sliding frame 42, which facilitates the installation of the iron core body 5 and improves the practicality of the device.

[0036] Reference Figure 3-5 The auxiliary fixing mechanism 6 includes a telescopic baffle 61, one end of which is fixedly connected to a pin 62. A connecting part 63 is fixedly connected to one side of the inner wall of the transformer housing 1. A knob 64 is rotatably connected to the middle of one side end face of the connecting part 63. A connecting rod 65 is fixedly connected to one side of the outer wall of the knob 64. A retaining ring 66 is fixedly connected to one end of the connecting rod 65. A sliding groove 67 is formed in the middle of one side end face of the connecting part 63. A spring 68 is fixedly connected to one end of the outer wall of the sliding groove 67. A locking block 69 is fixedly connected to one end of the spring 68. A locking block 69 is formed at the lower end of one side end face of the connecting part 63. The device extends the telescopic baffle 61 by pulling open one end, and then inserts the pin 62 at one end of the telescopic baffle 61 into the insertion interface 610 on the connecting part 63. After insertion, the knob 64 is turned. The knob 64 drives the connecting rod 65 and the retaining ring 66 to rotate at a certain angle and pass through one end of the insertion interface 610 to form a locking connection with the pin 62. At the same time, the retaining ring 66 moves away from the spring 68 and pushes the retaining block 69 out of the slide groove 67 to block the connecting rod 65 and prevent the retaining ring 66 from reversing. This achieves auxiliary fixation of the upper end of the iron core body 5 and improves the practicality of the device.

[0037] A sealing door 2 is rotatably connected to the middle of one side end face of the transformer housing 1. Multiple connecting ends 3 are provided on the upper end face of the transformer housing 1. The upper end of the sliding plate 47 is threadedly connected to the iron core body 5. The sealing door 2 and the clamping plate 46 are tightly attached to each other to help prevent loosening. The connecting ends 3 are used for normal working connection of the transformer. The sliding plate 47 supports the iron core body 5 and slides into the sliding frame 42 to achieve convenient installation.

[0038] One end of the elastic telescopic rod 44 is slidably connected to one side of the outer wall of the side slot 43, and one end of the clamping plate 46 is engaged with one end of the sliding frame 42. The elastic telescopic rod 44 can extend normally and give full play to its elastic advantages, and the clamping plate 46 can use its elasticity to fix one end of the sliding frame 42.

[0039] A slot 611 is provided on one side of the inner wall of the transformer housing 1. One side of the outer wall of the slot 611 is engaged with one end of the telescopic baffle 61. The slot 611 is used for placement of the telescopic baffle 61 during the auxiliary fixing stage to avoid obstructing the installation of the iron core body 5.

[0040] One side of the outer wall of the slide groove 67 is slidably connected to one end face of the locking block 69. The spring 68 can use its elasticity to make the locking block 69 pop out of the slide groove 67 and be restricted by the outer wall of the slide groove 67. Therefore, the locking block 69 blocks the rotation path of the connecting rod 65 at one end of the retaining ring 66, thereby fixing the pin 62 and the telescopic baffle 61 at one end.

[0041] One end of the retaining ring 66 passes through one end of one side of the insertion interface 610 and forms a locking connection with one end of the pin 62. The pin 62 can be positioned by the depth of the insertion interface 610 and the locking point of the retaining ring 66.

[0042] Working principle: The device pulls the locking plate 46, causing the elastic telescopic rod 44 at one end of the sliding frame 42 to extend, disengaging the locking plate 46 from one end of the sliding frame 42. Twisting the locking plate 46 causes the linkage rod 45 and the elastic telescopic rod 44 to change angle, thus creating a sliding opening for the sliding frame 42. Subsequently, the sliding plate 47 and the iron core body 5 threadedly connected to it are slidably inserted. After being inserted into the sliding frame 42, the locking plate 46 is pulled and aligned with one end of the sliding frame 42 and then released. The elasticity of the elastic telescopic rod 44 causes the locking plate 46 to extend. 6. The spring returns and engages with one end of the sliding frame 42. The device extends the telescopic baffle 61 by pulling open one end, and then inserts the pin 62 at one end of the telescopic baffle 61 into the insertion interface 610 on the connecting part 63. After the insertion is in place, the knob 64 is turned. The knob 64 drives the connecting rod 65 and the retaining ring 66 to rotate at a certain angle and pass through one end of the insertion interface 610 to form an engaging connection with the pin 62. At the same time, the retaining ring 66 moves away from the spring 68 and pushes the retaining block 69 out of the slide groove 67 to block the connecting rod 65 and reverse the retaining ring 66.
