DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 6As shown, the utility model discloses a rotation-stopping mechanism for an electromagnet, which is composed of a rotation-stopping shell 1, an iron core 2 and an enameled wire 3, wherein the iron core 2 and the enameled wire 3 are both located in the rotation-stopping shell 1, and the length direction of the iron core 2 extends up and down, and the enameled wire 3 is located in the circumference of the iron core 2, and the rotation-stopping shell 1 comprises a base 12 and an upper cover 11, wherein the base 12 is cylindrical and has an opening on the upper side, and an installation cavity 121121 is arranged in the base 12, and the upper cover 11 is disc-shaped and is located on the base 12, and the base 12 is located in the installation cavity 121121 and is provided with a ring-shaped positioning seat 122, and the length direction of the positioning seat 122 extends up and down, and a plurality of rotation-stopping plugs 111 are protrudingly arranged on the upper cover 11, and each rotation-stopping plug 111 is arranged along the upper cover 11 are arranged at circumferential intervals, the base 12 is located on the positioning seat 122 and corresponding to each anti-rotation plug block 111 is provided with a anti-rotation slot 1221, and the upper cover 11 is provided with a threading groove 112, 1. The upper side of the enameled wire 3 located on the iron core 2 can pass through the threading groove 112 to pass through the anti-rotation shell 1, and because the threading groove 112 is provided on the cover body, the upper side of the enameled wire 3 can only move in the threading groove 112 and will not move randomly with the shaking of the electromagnet; 2. Because when the upper cover 11 falls into the installation cavity 121121 of the base 12, at this time, each anti-rotation plug block 111 is respectively located in the corresponding anti-rotation slot 1221, so when the electromagnet is rotated, the upper cover 11 cannot rotate or slip compared with the base 12 to affect the normal use of the electromagnet.

[0024] Among them, each of the anti-rotation plug blocks 111 is arranged in an arc shape with an opening facing inward, and the base 12 is provided with a loading groove 127 connected to the corresponding anti-rotation slot 1221 above each anti-rotation slot 1221. 1. Since the base 12 is provided with a loading groove 127 connected to the corresponding anti-rotation slot 1221 above each anti-rotation slot 1221, each anti-rotation plug block 111 first passes through each loading groove 127 after entering the base 12 and then reaches the corresponding anti-rotation slot 12 21, so the setting of each loading groove 127 can provide convenience for the upper cover 11 to be rotated onto the base 12; 2. Since each anti-rotation plug block 111 is arranged in an arc shape with its opening facing inward, the width of each anti-rotation slot 1221 and the loading groove 127 is greater than the width of the outer side. Similarly, the width of the outer side of each anti-rotation plug block 111 is smaller than the width of the inner side. Therefore, each anti-rotation plug block 111 can fall into the corresponding loading groove 127 and anti-rotation slot 1221 more smoothly.

[0025] The base 12 is located above the upper cover 11 and is provided with a sealing ring 124. The sealing ring 124 abuts against the upper end surface of the upper cover 11. The cross section of the sealing ring 124 is inclined from the inside to the outside from the bottom to the top. The sealing ring 124 is located at each stop plug 111 and is correspondingly provided with a through slot 1241. Since the cross section of the sealing ring 124 is inclined from the inside to the outside from the bottom to the top, the sealing ring 124 is arranged in a shape of being wide at the bottom and narrow at the top, so that: the lower end surface of the sealing ring 124 can be stably located on the upper end surface of the upper cover 11 1. When the electromagnet is rotated and inverted without the action of external force, the upper cover 11 will not pass over the sealing ring 124 and separate from the base 12; 2. When the upper cover 11 passes over the sealing ring 124 and thus completes the cooperation between the anti-rotation blocks 111 of the upper cover 11 and the corresponding anti-rotation slots 1221, since the upper side of the sealing ring 124 is the narrowest, the upper cover 11 will first contact the inner side of the sealing ring 124 from top to bottom and then more smoothly pass over the sealing ring 124 to complete the cooperation between the anti-rotation blocks 111 and the corresponding anti-rotation slots 1221.

[0026] Among them, it also includes a limit assembly 4 set corresponding to each anti-rotation plug block 111, each of the limit assemblies 4 includes a limit column 41 slidably installed on the base 12 along the up and down directions, and each of the anti-rotation plug blocks 111 is provided with a limit groove 1111 for the corresponding limit column 41 to be inserted. Due to the installation and continuous use of the upper cover 11 and the base 12, each anti-rotation plug block 111 may be worn in cooperation with the corresponding anti-rotation slot 1221, so that each anti-rotation plug block 111 is worn and locked in the corresponding anti-rotation plug. The upper cover 11 cannot be stably installed with the base 12 due to the shaking in the groove 1221. Therefore, the limit columns 41 that are installed in the upper and lower directions through sliding in each limit assembly 4 and can be inserted into the corresponding stop block 111 can further locate and determine the position of each stop block 111 in the corresponding stop slot 1221. Even if the stop block 111 in each stop slot 1221 is worn, it cannot shake in the corresponding stop slot 1221 due to the existence of each limit column 41.

[0027] Among them, the base 12 is provided with a sliding groove 125 for the corresponding limiting column 41 to be installed below each limiting column 41, and the limiting assembly 4 also includes a limiting plate 42 and an operating handle 43 with the same number as the limiting column 41, each of the limiting plates 42 is located at the bottom of the corresponding limiting column 41, and the diameter of each limiting plate 42 is larger than the diameter of the corresponding limiting column 41, and each of the sliding grooves 125 is provided with a limiting hole 126 with the same diameter as the corresponding limiting column 41 above each limiting plate 42, and each of the limiting holes 126 is communicated with the corresponding sliding groove 125, and the base 12 is provided with a matching groove 123 corresponding to each sliding groove 125, and each operating handle 43 is fixedly connected to the corresponding limiting plate 42 by welding or the like, and the outer side of each operating handle 43 is against the base 12, 1. Due to each The operating handle 43 is fixed to the corresponding limit plate 42 and the outer side of each operating handle 43 is evenly opposed to the base 12. Therefore, by applying force to each operating handle 43, the limit plate 42 and the limit column 41 can be driven to move up and down in the sliding groove 125, thereby realizing the cooperation or separation of the limit column 41 and the corresponding anti-rotation plug 111. Therefore, in the absence of external force, each limit column 41 can be inserted into the corresponding anti-rotation plug 111 to make each anti-rotation plug 111 stably located in the corresponding anti-rotation slot 1221; 2. The diameter of the sliding groove 125 is the same as that of the limit plate 42 and is larger than the limit block and the limit column 41. Therefore, the limit plate 42 cannot move upward beyond the limit hole 126. Therefore, the sliding groove 125 and the limit hole 126 can limit the moving path of the limit column 41 and the limit plate 42.

[0028] Among them, it also includes a guide column 5 located in each matching groove 123, and each of the limit columns 41 is provided with a guide groove 411 for the guide column 5 to be placed in the corresponding guide column 5. The limit assembly 4 also includes a spring 44 with the same number as the limit column 41, and each spring 44 is respectively located in the circumference of the corresponding guide column 5 and one end is fixedly connected to the corresponding limit plate 42 by welding or the like, and the other end is fixedly connected to the base 12 by welding or the like. 1. Due to the arrangement of each guide column 5, in the process of each limit column 41 moving up and down, each limit column 41 can move along the length direction of the guide column 5 and limit the up and down movement path of each limit column 41; 2. Since each spring 44 is located in the circumference of the corresponding guide column 5 and one end is fixed to the corresponding limit plate 42 and the other end is fixed to the base 12 2 is fixed, so when it is necessary to move the limit column 41 downward and separate it from the corresponding anti-rotation plug block 111, by applying force to the operating handle 43, the operating handle 43 moving downward can drive the limit plate 42 and the limit column 41 to move downward, and squeeze the corresponding spring 44 to separate each limit column 41 from the corresponding anti-rotation plug block 111. When it is necessary to insert each limit column 41 into the corresponding anti-rotation plug block 111, the elastic force of the spring 44 itself can drive the spring 44 to tend to restore, and then the elastic force of the spring 44 can apply an upward force to the limit plate 42, so that each limit column 41 is inserted upward into the corresponding anti-rotation plug block 111. Therefore, the setting of each spring 44 can make each limit column 41 move upward more smoothly and quickly to be inserted into the corresponding anti-rotation plug block 111.

[0029] Among them, the outer side of each operating handle 43 is fixedly provided with a positioning block 431 by means of one-piece molding, welding, etc., and each positioning block 431 is detachably connected to the base 12. Since the positioning block 431 on the outer side of each operating handle 43 can be detachably connected to the base 12, when each limit column 41 is inserted into the corresponding anti-rotation block 111, since the position of each operating handle 43 on the base 12 is determined, each limit column 41 is further stably located on the corresponding limit block, thereby further improving the stability of the connection between the upper cover 11 and the base 12.

[0030] Preferably, the base 12 is provided with a positioning slot 128 corresponding to each positioning plug block 431, and each positioning plug block 431 is provided with an inwardly recessed mating slot 4311, and each mating slot 4311 is arranged in a ring shape. The base 12 is provided with a mating plug block 1281 that cooperates with the corresponding mating slot 4311 in each positioning slot 128. Since each positioning plug block 431 is provided with a mating slot 4311, the part of each positioning plug block 431 located at the mating slot 4311 close to the base 12 needs to be forcibly passed over the corresponding mating plug block 1281 when inserted into the positioning slot 128 in the base 12, thereby realizing the mating of the mating slot 4311 and the mating plug block 1281, and when each positioning plug block 431 needs to be aligned with the base 12 During separation, a force is applied to the operating handle 43 away from the side of the positioning slot 128, and then a force is applied to each positioning block 431 away from the side of the positioning slot 128, so that the part of each positioning block 431 located at the side of the mating slot 4311 close to the base 12 moves toward the side away from the base 12 and forcibly passes over the corresponding mating block 1281, thereby realizing the separation of each positioning block 431 and the corresponding positioning slot 128, thereby releasing the connection between the operating handle 43 and the base 12, so that a downward force is applied to the operating handle 43, driving the limit plate 42 and the limit column 41 to move downward and separate from the corresponding anti-rotation block 111. Therefore, the setting of the mating block 1281 and the mating slot 4311 enables each operating handle 43 to be stably connected to the base 12.

[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
