Description

Technical Field

[0001] The utility model relates to the technical field of magnets, in particular to a multi-section magnet structure which is convenient for installation. Background Art

[0002] A magnet is a magnetic stone with magnetism. The ancient Greeks and Chinese discovered that there was a kind of naturally magnetized stone in nature and called it a "magnetite". This kind of stone could magically attract small iron pieces and always point in the same direction after being randomly swung. So early sailors used this kind of magnet as the earliest compass to distinguish directions at sea. After that, in the research and development of magnets, it was learned that the reason why magnets can generate magnetism is because of the action of electromagnetic force. Under the action of the magnetic field generated by the magnet, the arrangement of the electron magnetic moments of iron will change from disorder to order, so it is magnetized and generates a magnetic field. Of course, based on the working principle of the magnet, people are keen on developing and manufacturing magnets for use in real work and life. Among them, the multi-section magnet is formed by installing and connecting several artificially made single magnets. Although it is convenient to use and has good magnetic field performance, due to the characteristics of "like poles repel, opposite poles attract" of the magnetic field, it brings inconvenience to the production of multi-section magnets. Therefore, in the process of developing and utilizing magnets, corresponding treatment solutions need to be made for various properties of the magnets.

[0003] Chinese Patent Authorization Publication No.: CN216133728U, Authorization Publication Date: March 25, 2022, discloses a multi-section magnet assembly, including a fixed seat and a first magnet, a second magnet, a third magnet and a fourth magnet all arranged on the fixed seat. The first magnet is located between the first magnet and the third magnet, and the third magnet is located between the second magnet and the fourth magnet; the first magnet and the third magnet are both opposite in polarity to the second magnet and the fourth magnet; the first magnet, the second magnet, the third magnet and the fourth magnet are respectively provided with positioning holes, and both sides of the positioning holes are respectively communicated with limiting holes; the fixed seat is provided with four clamping members, and the clamping members are assembled with the positioning holes one by one. The clamping members are provided with limiting structures for clamping into the limiting holes. The disadvantage of this technical solution is that when manufacturing the multi-section magnet assembly, the first magnet, the second magnet, the third magnet and the fourth magnet are directly placed on the fixed seat. Through the limiting holes in the positioning holes of the first magnet, the second magnet, the third magnet and the fourth magnet, and in cooperation with the limiting structures on the clamping members on the fixed seat, the mechanical connection between the four magnets of the first magnet, the second magnet, the third magnet and the fourth magnet and the fixed seat is completed. Although the connection work has been completed, the connection work between the four magnets of the first magnet, the second magnet, the third magnet and the fourth magnet and the fixed seat is manually operated. Even if the fixed seat and the clamping members are made of metal and will be magnetized, the installation work of the multi-section magnet assembly is carried out in multiple steps, and the work is cumbersome and not simple enough.

[0004] In summary, the magnetic field characteristics of the magnet can be utilized to make a targeted installation structure, so that the installation work of the multi-segment magnet can be completed with simple operations. Content of the Utility Model

[0005] The utility model aims to overcome the deficiency that the installation work of the multi-segment magnet in the prior art is cumbersome, and provides a multi-segment magnet structure that is easy to install, with simple operations, and can complete the installation work through the magnetic field characteristics of the magnet.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A multi-segment magnet structure that is easy to install, including Magnet 1, Magnet 2 and a mounting base. Both Magnet 1 and Magnet 2 include several pieces. Magnet 1 is a positive magnetic field magnet, and Magnet 2 is a negative magnetic field magnet. The mounting base includes a control block and a limiting block. Both the control block and the limiting block include two pieces. The two limiting blocks are symmetrically distributed at the front and rear ends of the control block, and the two control blocks are symmetrically distributed at the left and right ends of the limiting block. The front and rear ends of the control block are respectively connected to the two limiting blocks. The control block is provided with a rolling cavity and several jacks, and the jacks communicate with the rolling cavity. A rolling bearing and a flap are installed on the control block. Both the rolling bearing and the flap include several pieces. The rolling bearing is placed in the rolling cavity, and the rolling bearing corresponds to the jack one by one. The rolling bearing includes an inner ring and an outer ring. The outer ring is in contact with the control block. A flap shaft is installed on the flap, and the two ends of the flap shaft are respectively connected to the two inner rings. A positive magnetic field block, an insulating block and a negative magnetic field block are sleeved inside the flap. The positive magnetic field block and the negative magnetic field block are respectively placed at the upper and lower ends of the insulating block. The positive magnetic field block and the negative magnetic field block are both connected to the insulating block. Magnet 1 matches the negative magnetic field block, and Magnet 2 matches the positive magnetic field block.

[0008] Such a design can install a mounting base through two control blocks and two limit blocks. The two limit blocks are symmetrically distributed at the front and rear ends of the control block, and the two control blocks are symmetrically distributed at the left and right ends of the limit block. In this way, the connection work between the front and rear ends of the control block and the two limit blocks is completed. That is, under the connection of the two limit blocks and the two control blocks, a frame structure is presented. The front, rear, left, and right ends of the mounting base are all limited, while the upper and lower ends are not limited. At the same time, the control block is provided with a rolling cavity and several jacks, and these jacks are communicated with the rolling cavity. The rolling cavities on the two control blocks can correspond to each other from left to right. A rolling bearing and a flap are also installed on the control block. The rolling bearing is placed in the rolling cavity and corresponds to the jacks one by one. The two ends of the flap shaft of the flap are respectively connected to the inner rings of the two rolling bearings. In this way, the flap can be directly controlled to turn over. With the cooperation of the flap shaft and the inner ring, the turning-over work of the flap can be carried out smoothly. Of course, a positive magnetic field block, an insulating block, and a negative magnetic field block are installed inside the flap. The positive magnetic field block and the negative magnetic field block are respectively placed at the upper and lower ends of the insulating block. Magnet one is a positive magnetic field magnet, and magnet two is a negative magnetic field magnet. That is, the magnetism of magnet one and the magnetism of magnet two are of opposite poles and have an effect of attracting each other. And magnet one is matched with the negative magnetic field block, and magnet two is matched with the positive magnetic field block. Then the tops of the turned-over adjacent flaps can be of opposite poles, that is, one is a negative magnetic field block and the other is a positive magnetic field block. In this way, the attraction work between magnet one and magnet two can be carried out, and magnet one and magnet two can be stably limited on the flap. At the same time, the outer ring of the rolling bearing is in contact with the control block. Then, under the action of the mutual attraction between magnet one and magnet two, the adjacent flaps can be driven to move towards each other under the limiting effect of the rolling cavity until magnet one and magnet two attract each other. In this way, multiple-section magnets can be successfully installed through the attracting effect of magnet one and magnet two, thereby enhancing the magnetism. Of course, both magnet one and magnet two contain several, so the quantity control of magnet one and the quantity control of magnet two can be controlled, that is, the length control of the multiple-section magnet. Here, the turning-over work of the flap is simple and easy. Under the magnetic effects of magnet one, magnet two, the positive magnetic field block, and the negative magnetic field block, simple operation is achieved, and the purpose of the installation work can be completed through the magnetic field characteristics of the magnet.

[0009] Preferably, the distribution shape of the rolling cavity is rectangular. The front end of the rolling cavity is placed at the front end of the control block, and the rear end of the rolling cavity is placed at the rear end of the control block. The distance between the front end of the rolling cavity and the bottom end of the control block is equal to the distance between the rear end of the rolling cavity and the bottom end of the control block. With this design, by making the distribution shape of the rolling cavity rectangular and placing the front end of the rolling cavity at the front end of the control block and the rear end at the rear end of the control block, the outer ring of the rolling bearing can smoothly roll back and forth under the limiting effect of the rolling cavity, that is, the flap connected to the inner ring of the rolling bearing can smoothly move back and forth under the limiting effect of the control block. Of course, the distance between the front end of the rolling cavity and the bottom end of the control block is equal to the distance between the rear end of the rolling cavity and the bottom end of the control block, which means that the movement of the flap is parallel to the distribution of the bottom end of the control block, and the movement work is carried out stably without the situation of height difference between adjacent flaps.

[0010] Preferably, the top end of the control block is connected to the top end of the limiting block, and the bottom end of the control block is connected to the bottom end of the limiting block. The top end of the mounting seat is provided with an opening, and the flap is placed at the bottom end of the mounting seat. The bottom end of the first magnet is detachably connected to the negative magnetic field block, and the bottom end of the second magnet is detachably connected to the positive magnetic field block. The top ends of the first magnet and the second magnet both pass through the opening and are placed at the outer end of the mounting seat. With this design, by connecting the top end of the control block to the top end of the limiting block and the bottom end of the control block to the bottom end of the limiting block, there will be openings at both the top and bottom ends of the mounting seat. Since the bottom end of the mounting seat is blocked by the flap, there is only an opening at the top end of the mounting seat. And the bottom end of the first magnet is detachably connected to the negative magnetic field block, the bottom end of the second magnet is detachably connected to the positive magnetic field block, and the top ends of the first magnet and the second magnet both pass through the opening and are placed at the outer end of the mounting seat, so that the top ends of the first magnet and the second magnet at the outer end of the mounting seat can be directly controlled to connect or disconnect the bottom end of the first magnet to the negative magnetic field block and the bottom end of the second magnet to the positive magnetic field block, that is, the limiting work or disassembly work of the first magnet and the second magnet can be controlled, so as to implement the installation work of the multi-segment magnet.

[0011] Preferably, the top end of the first magnet is provided with a mark S, and the top end of the second magnet is provided with a mark N. With this design, by providing a mark S at the top end of the first magnet and a mark N at the top end of the second magnet, the distribution and quantity of the first magnet and the second magnet can be smoothly seen, so as to carry out the installation of the multi-segment magnet, that is, the length control of the multi-segment magnet can be controlled, and then the magnetism of the multi-segment magnet can also be controlled.

[0012] Preferably, two openings are provided on the flap, and the two openings are respectively located at the top and bottom of the flap. The top of the positive magnetic field block is placed at the opening at the top of the flap, the bottom of the positive magnetic field block is connected to the top of the insulating block, the bottom of the negative magnetic field block is placed at the opening at the bottom of the flap, and the top of the negative magnetic field block is connected to the bottom of the insulating block. Such a design is to open two openings on the flap, with the two openings respectively located at the top and bottom of the flap, so that the top of the positive magnetic field block can be placed at the opening at the top of the flap, the bottom of the positive magnetic field block is connected to the top of the insulating block, the bottom of the negative magnetic field block is placed at the opening at the bottom of the flap, and the top of the negative magnetic field block is connected to the bottom of the insulating block. Then, when controlling the flap to turn over, the top of the positive magnetic field block or the top of the negative magnetic field block can face the opening direction, and then the magnet one or magnet two can be directly controlled to insert through the opening, that is, the top of the positive magnetic field block attracts magnet two, and the top of the negative magnetic field block attracts magnet one, so as to complete the installation work of the multi-section magnet.

[0013] Preferably, a plurality of limiting insulating blocks are installed on the mounting seat, and the magnet one, magnet two and the mounting seat are all detachably connected to the limiting insulating blocks. Such a design is to install a plurality of limiting insulating blocks on the mounting seat. Here, the magnet one, magnet two and the mounting seat are all detachably connected to the limiting insulating blocks, that is, the limiting insulating blocks can be inserted between the magnet one and magnet two under the limiting effect of the mounting seat, so as to weaken the mutual attraction effect between the magnet one and magnet two. Only when the limiting insulating blocks are removed can the magnet one and magnet two attract each other until they are attracted.

[0014] The beneficial effects of the present utility model are as follows: it can achieve simple operation and complete the installation work through the magnetic field characteristics of the magnet; it is convenient for the installation and disassembly of the flap, limiting insulating blocks and mounting seat; and it can control the length of the multi-section magnet.

[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 shown in the embodiments, a multi - section magnet structure facilitating installation includes magnet one 4, magnet two 5 and a mounting seat. Both magnet one 4 and magnet two 5 include several pieces. Magnet one 4 is a positive magnetic field magnet, and magnet two 5 is a negative magnetic field magnet.

The front and rear ends of control block 1 are respectively connected to the two limit blocks 2. There are a rolling cavity 8 and several jacks 12 on control block 1. The jacks 12 communicate with the rolling cavity 8. A rolling bearing and a flap 7 are installed on control block 1. Both the rolling bearing and the flap 7 include several pieces. The rolling bearing is placed in the rolling cavity 8, and the rolling bearing corresponds to the jack 12 one by one. The rolling bearing includes an inner ring 11 and an outer ring 10. The outer ring 10 contacts control block 1. A flap shaft 9 is installed on flap 7. The two ends of flap shaft 9 are respectively connected to the two inner rings 11. A positive magnetic field block 13, an insulating block 14 and a negative magnetic field block 15 are sleeved inside flap 7. The positive magnetic field block 13 and the negative magnetic field block 15 are respectively placed at the upper and lower ends of the insulating block 14. Both the positive magnetic field block 13 and the negative magnetic field block 15 are connected to the insulating block 14. Magnet one 4 matches the negative magnetic field block 15, and magnet two 5 matches the positive magnetic field block 13.

[0025] As Figure 4 shown, the distribution shape of the rolling cavity 8 is rectangular. The front end of the rolling cavity 8 is placed at the front end of control block 1, and the rear end of the rolling cavity 8 is placed at the rear end of control block 1. The distance between the front end of the rolling cavity 8 and the bottom end of control block 1 is equal to the distance between the rear end of the rolling cavity 8 and the bottom end of control block 1.

[0026] As Figure 2 ,Figure 3 and Figure 7 As shown, the top of the control block 1 is connected to the top of the limit block 2, the bottom of the control block 1 is connected to the bottom of the limit block 2, an opening 3 is provided at the top of the mounting base, the flap 7 is placed at the bottom of the mounting base, the bottom of the first magnet 4 is detachably connected to the negative magnetic field block 15, the bottom of the second magnet 5 is detachably connected to the positive magnetic field block 13, and the tops of the first magnet 4 and the second magnet 5 both pass through the opening 3 and are placed at the outer end of the mounting base. A mark S is provided at the top of the first magnet 4, and a mark N is provided at the top of the second magnet 5. Two openings 16 are provided on the flap 7, and the two openings 16 are respectively placed at the top and bottom of the flap 7. The top of the positive magnetic field block 13 is placed at the opening 16 at the top of the flap 7, the bottom of the positive magnetic field block 13 is connected to the top of the insulating block 14, the bottom of the negative magnetic field block 15 is placed at the opening 16 at the bottom of the flap 7, and the top of the negative magnetic field block 15 is connected to the bottom of the insulating block 14.

[0027] As Figure 1 and Figure 4 shown, a number of limit insulating blocks 6 are installed on the mounting base, and the first magnet 4, the second magnet 5 and the mounting base are all detachably connected to the limit insulating blocks 6.

[0028] First, the control block 1 and the limit block 2 are manufactured. Here, a number of control blocks 1 and limit blocks 2 can be manufactured for backup. Here, a rolling cavity 8 and a number of jacks 12 need to be opened on the control block 1. The jacks 12 communicate with the rolling cavity 8, and the distribution shape of the rolling cavity 8 is rectangular. The front end of the rolling cavity 8 is placed at the front end of the control block 1, the rear end is placed at the rear end of the control block 1, and the distance between the front end of the rolling cavity 8 and the bottom of the control block 1 is equal to the distance between the rear end of the rolling cavity 8 and the bottom of the control block 1. Generally speaking, the cross-sectional shapes of the control block 1 and the limit block 2 can both be selected as square, so the rolling cavity 8 can be parallel to the bottom of the control block 1. At the same time, a number of rolling bearings also need to be installed in the rolling cavity 8, so that the outer ring 10 of the rolling cavity 8 contacts the control block 1, and thus the manufacture of the control block 1 is completed.

[0029] Next, the connection work of the control block 1 and the limit block 2 needs to be carried out. Here, two control blocks 1 and two limit blocks 2 are selected. Then, the flap 7 is controlled so that both ends of the flap shaft 9 of the flap 7 are respectively connected to the inner rings 11 of the rolling bearings of the two control blocks 1. In this way, the rolling cavities 8 on the two control blocks 1 face each other correspondingly. Thus, a number of flaps 7 are successfully connected to the control block 1. Of course, the number of flaps 7 to be installed here can be determined according to the number of magnets 4 of the first type and the number of magnets 5 of the second type on the multi-segment magnet, which is the sum of the number of magnets 4 of the first type and the number of magnets 5 of the second type. It should be noted here that the rolling bearing needs to be stably limited within the rolling cavity 8 to prevent the rolling bearing from being disengaged from the limit of the rolling cavity 8 when the flap 7 is controlled to move, and the flap shaft 9 passes through the jack 12 and is placed within the rolling cavity 8. After the installation work of the flap 7 is completed, the installation of the mounting seat needs to be carried out. The installation of this mounting seat is to symmetrically distribute the two limit blocks 2 at the front and rear ends of the control block 1, and symmetrically distribute the two control blocks 1 at the left and right ends of the limit block 2. The front and rear ends of the control block 1 are respectively connected to the two limit blocks 2. This connection can directly use nails to nail the top end of the control block 1 to the top end of the limit block 2 and nail the bottom end of the control block 1 to the bottom end of the limit block 2. A frame-type mounting seat with a limiting effect in all directions of front, rear, left, and right is successfully installed.

[0030] Now, the installation of the multi-segment magnet needs to be started. Check the prepared magnets 4 of the first type and magnets 5 of the second type. There are several of both the magnets 4 of the first type and the magnets 5 of the second type. The magnets 4 of the first type are positive magnetic field magnets, and the magnets 5 of the second type are negative magnetic field magnets. That is, the magnets 4 of the first type and the magnets 5 of the second type are of opposite polarities and will attract each other. Moreover, a mark S is provided at the top end of the magnet 4 of the first type, representing that the magnet 4 of the first type is the positive pole, and a mark N is provided at the top end of the magnet 5 of the second type, representing that the magnet 5 of the second type is the negative pole. By clearly seeing the mark S and the mark N, the magnets 4 of the first type and the magnets 5 of the second type can be successfully extracted. This not only reduces the error probability of extracting the magnets but also can control the number of magnets 4 of the first type and the number of magnets 5 of the second type extracted. Of course, in order to avoid the adverse effects caused by the mutual attraction of the magnets 4 of the first type and the magnets 5 of the second type during the installation process, a number of prepared limit insulating blocks 6 also need to be placed beside them.

[0031] After the multi - segment magnet installation work starts, it is first necessary to know the quantity of magnet one 4 and magnet two 5 required for this multi - segment magnet. First, insert the first limiting insulating block 6 into the position at the front end of the rolling cavity 8. Here, in order to facilitate the insertion of the limiting insulating block 6 in the limited state, according to the length of the flap 7, several insertion slots can be opened on the control block 1, and the insertion slots are placed at the upper end of the rolling cavity 8. In this way, the left and right ends of the limiting insulating block 6 can smoothly move down under the limiting effect of the two insertion slots corresponding to the positions on the two control blocks 1. Then, the flap 7 at the front end position of the rolling cavity 8 can be controlled to turn over. Since the positive magnetic field block 13, insulating block 14, and negative magnetic field block 15 are sleeved inside the flap 7, the positive magnetic field block 13 and the negative magnetic field block 15 are respectively placed at the upper and lower ends of the insulating block 14. The top of the positive magnetic field block 13 is placed at the opening 16 at the top of the flap 7, and the bottom is connected to the top of the insulating block 14. The bottom of the negative magnetic field block 15 is placed at the opening 16 at the bottom of the flap 7, and the top is connected to the bottom of the insulating block 14. In this way, under the control of the inner ring 11, the turning - over work of the flap 7 can be carried out smoothly. After turning over, the flap 7 can be directly pushed, so that the outer ring 10 can smoothly move back and forth under the limitation of the rolling cavity 8 until the front end of the flap 7 abuts against the limiting insulating block 6. Then, the insertion work of several limiting insulating blocks 6 and the turning - over and moving work of the flap 7 can be carried out several times. Of course, the tops of adjacent flaps 7 need to be in a state of opposite poles. Since the front - most and the rearmost limiting insulating blocks 6 need to be pushed by an external force, compression springs can also be installed at the front and rear ends of the rolling cavity 8 to make the compression springs abut against the two limiting insulating blocks 6 at the front - most and rearmost ends of the rolling cavity 8.

[0032] Next, it is necessary to place the first magnet 4 and the second magnet 5. Regarding the bottom end of the mounting base, depending on whether the top of the flap 7 is the positive magnetic field block 13 or the negative magnetic field block 15, the placement of the first magnet 4 and the second magnet 5 can be selectively carried out. If the top of the flap 7 is the positive magnetic field block 13, then the second magnet 5 needs to be inserted through the opening 3 until the bottom end of the second magnet 5 is placed on the positive magnetic field block 13. Since the second magnet 5 and the positive magnetic field block 13 are matched, that is, the opposite poles attract each other, the second magnet 5 can be stably attracted to the positive magnetic field block 13. Similarly, if the top of the flap 7 is the negative magnetic field block 15, then the first magnet 4 needs to be inserted through the opening 3 until the bottom end of the first magnet 4 is placed on the negative magnetic field block 15. Since the first magnet 4 and the negative magnetic field block 15 are matched, that is, the opposite poles attract each other, the first magnet 4 can be stably attracted to the negative magnetic field block 15. In this way, the placement of several first magnets 4 and second magnets 5 can be carried out smoothly. Of course, one of the adjacent two flaps 7 is the first magnet 4 and the other is the second magnet 5. Since the limiting insulating block 6 has no magnetism, it will not only not be attracted by the first magnet 4 or the second magnet 5, but also weaken the mutual attraction effect between the adjacent first magnet 4 and the second magnet 5.

[0033] Finally, the limiting insulating block 6 clamped between the adjacent first magnet 4 and the second magnet 5 is taken out. Under the elastic effect of the compression spring, combined with the characteristics of like poles repelling and opposite poles attracting, the first magnet 4 and the second magnet 5 can attract each other, thereby starting the installation of the multi-segment magnet. During the process of the first magnet 4 and the second magnet 5 attracting each other, the adjacent flaps 7 can also be driven to move relative to each other until the first magnet 4 and the second magnet 5 are attracted. The two limiting insulating blocks 6 at the frontmost and rearmost ends of the rolling cavity 8 do not need to be taken out to avoid affecting the compression effect of the compression spring.

[0034] In this way, the flipping operation of the flap 7 is simple and easy. Under the magnetic effects of the first magnet 4, the second magnet 5, the positive magnetic field block 13, and the negative magnetic field block 15, the operation is simplified, and the installation work can be completed through the magnetic field characteristics of the magnets. The materials of the control block 1, the limiting block 2, the limiting insulating block 6, the flap 7, and the insulating block 14 can be selected as non-magnetic plastics, so as not to affect the magnetic fields of the first magnet 4, the second magnet 5, the positive magnetic field block 13, and the negative magnetic field block 15. Of course, in order to achieve better working effects, the inner ring 11 and the outer ring 10 of the rolling bearing, as well as the flap shaft 9, can also be selected as non-magnetic plastics.
