[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] This utility model embodiment provides a magnetic fixing base 100, such as Figures 1-5 As shown, the magnetic mounting base 100 includes a base body 110 and a magnetic ring 120. The base body 110 includes an outer ring 111 and a first inner ring 112. The outer ring 111 surrounds the first inner ring 112 and is spaced apart from it, forming a mounting groove 113 between the outer ring 111 and the first inner ring 112. The first inner ring 112 includes a plurality of limiting blocks 1121, which are spaced apart circumferentially on the first inner ring 112. The magnetic ring 120 is mounted in the mounting groove 113.

[0030] It is worth mentioning that the first inner ring 112 is equivalent to the inner wall of the mounting groove in the prior art. In the prior art, the inner wall is thin and has poor toughness. When the inner wall is in an interference fit with the magnetic ring 120, it is easily crushed by the magnetic ring 120. When the inner wall is in a clearance fit with the magnetic ring 120, it is also easily damaged when the magnetic fixing seat 100 falls and collides. Therefore, the inner wall in the prior art is easily damaged by force. In this application, the first inner ring 112 includes several limiting blocks 1121. Since the limiting blocks 1121 are spaced apart, they can better absorb energy through deformation, resulting in better toughness of the first inner ring 112 and making it less prone to damage by force.

[0031] refer to Figures 2-5 In a specific embodiment, the seat body 110 further includes a second inner ring 114, which is surrounded by an outer ring 111 and is spaced apart from the outer ring 111. A groove 115 is formed between the second inner ring 114 and the outer ring 111. A first inner ring 112 is disposed in the groove 115. Each limiting block 1121 is provided with a support rib 116 on the side facing the second inner ring 114. The support rib 116 connects the limiting block 1121 and the second inner ring 114.

[0032] Specifically, in this embodiment, a support rib 116 is provided on the side of the limiting block 1121 facing away from the magnetic ring 120. Since the support rib 116 connects the limiting block 1121 and the second inner ring 114, the support rib 116 can support the limiting block 1121, increase the structural strength of the limiting block 1121, and make the limiting block 1121 less prone to breakage.

[0033] refer to Figures 2-5 In a specific embodiment, the magnetic fixing base 100 also includes a cover 130, which is positioned at the opening of the groove 115 so that the cover 130 can cooperate with the base 110 to cover the magnetic ring 120.

[0034] This embodiment demonstrates a specific implementation method for confining the magnetic ring 120 within the mounting groove 113. Specifically, a cover 130 is positioned at the opening of the mounting groove 113, allowing the magnetic ring 120 to be confined within it. Since the cover 130 cooperates with the base 110 to conceal the magnetic ring 120, it prevents the magnetic ring 120 from being exposed. This not only enhances the aesthetics of the magnetic mounting base 100 but also prevents environmental contaminants from entering the groove 115.

[0035] refer to Figures 2-5 In a specific embodiment, the base 110 is provided with a receiving groove 118, the groove opening of the groove 115 is located at the bottom of the receiving groove 118, and the cover 130 is installed in the mounting groove 113.

[0036] By implementing this embodiment, the cover 130 can be concealed within the receiving groove 118, preventing the cover 130 from protruding from the surface of the base 110. This not only protects the cover 130 to a certain extent but also enhances the aesthetics of the magnetic fixing base 100.

[0037] In a specific embodiment, the cover 130 is glued to the mounting groove 113.

[0038] This embodiment demonstrates a specific implementation method for installing the cover 130 in the mounting groove 113. Specifically, the cover 130 is glued to the mounting groove 113, which not only simplifies assembly but also ensures a very secure connection.

[0039] refer to Figures 2-5 In some embodiments, the seat 110 further includes a connecting arm 117, one end of which is connected to the outer ring 111, and the other end extends away from the first inner ring 112. The connecting arm 117 is provided with a clearance groove 1171, and a plurality of reinforcing ribs 1172 connected to the groove wall of the clearance groove 1171 are provided in the clearance groove 1171.

[0040] Specifically, the clearance groove 1171 can reduce the amount of material used in the connecting arm 117 and reduce its weight, which is beneficial to improving portability and reducing transportation costs. Since the clearance groove 1171 will reduce the structural strength to a certain extent, this embodiment, based on the clearance groove 1171, provides several reinforcing ribs 1172 connected to the groove wall of the clearance groove 1171, thereby increasing the structural strength to a certain extent.

[0041] refer to Figures 2-5 In a specific embodiment, the magnetic fixing base 100 also includes a baffle 140, which is positioned at the opening of the clearance groove 1171. The opening of the clearance groove 1171 is located at the bottom of the receiving groove 118. The cover 130 is also positioned on the side of the baffle 140 away from the reinforcing rib 1172.

[0042] Specifically, the baffle 140 can cover the opening of the clearance groove 1171, preventing the reinforcing rib 1172 from being exposed. This not only increases the aesthetics of the magnetic mounting base 100 but also prevents environmental pollutants from entering the clearance groove 1171. If the cover 130 does not cover the side of the baffle 140 away from the reinforcing rib 1172, both the cover 130 and the baffle 140 will be exposed on the outer surface of the magnetic mounting base 100, resulting in a less aesthetically pleasing appearance. To solve this technical problem, the opening of the clearance groove 1171 is located at the bottom of the receiving groove 118, and the cover 130 is also positioned on the side of the baffle 140 away from the reinforcing rib 1172, so that the cover 130 can cover the baffle 140, thereby improving the aesthetics of the magnetic mounting base 100.

[0043] refer to Figures 2-5 In a specific embodiment, the clearance groove 1171 is provided with a threaded hole (not shown in the figure), and the magnetic fixing base 100 also includes a screw 150, which passes through the baffle 140 and is connected to the threaded hole, thereby setting the baffle 140 at the opening of the clearance groove 1171.

[0044] This embodiment demonstrates a specific implementation method for connecting the baffle 140 to the seat 110. Specifically, the baffle 140 is installed on the seat 110 using a screw 150. This connection method can provide a large axial preload, so that the baffle 140 and the seat 110 are firmly connected together.

[0045] Furthermore, multiple threaded holes can be provided, and multiple threaded parts 150 are provided accordingly, which can further increase the connection stability between the baffle 140 and the seat 110.

[0046] refer to Figures 2-5 In some embodiments, an annular groove 1131 is provided at the bottom of the mounting groove 113 near the first inner ring 112. The annular groove 1131 surrounds the first inner ring 112 and is adjacent to the first inner ring 112.

[0047] Specifically, the bottom of the first inner ring 112 has the worst deformation capability. By implementing this embodiment, the magnetic ring 120 can be effectively prevented from contacting the bottom of the first inner ring 112, thereby reducing the probability of the first inner ring 112 being damaged by force.

[0048] refer to Figures 2-5 In one specific embodiment, the first inner ring 112 further includes a plurality of connecting ribs 1122, all of which are adjacent to the annular groove 1131. Any adjacent limiting blocks 1121 are connected by the connecting ribs 1122, and the plurality of connecting ribs 1122 are flush with the opening of the annular groove 1131.

[0049] Specifically, the connecting rib 1122 can increase the structural strength of the bottom of the first inner ring 112. Furthermore, because the presence of the connecting rib 1122 makes the position of the first inner ring 112 adjacent to the annular groove 1131 form a complete ring, the bottom of the first inner ring 112 has poor deformation capacity. The connecting rib 1122 is flush with the opening of the annular groove 1131, which can effectively prevent the magnetic ring 120 from contacting the connecting rib 1122, reducing the probability of damage to the first inner ring 112 under stress.

[0050] refer to Figures 2-5In another specific embodiment, the first inner ring 112 further includes a plurality of connecting ribs 1122, all of which are adjacent to the annular groove 1131. Any adjacent limiting blocks 1121 are connected by the connecting ribs 1122, and the plurality of connecting ribs 1122 are lower than the opening of the annular groove 1131.

[0051] Specifically, the connecting rib 1122 can increase the structural strength of the bottom of the first inner ring 112. Furthermore, because the presence of the connecting rib 1122 makes the position of the first inner ring 112 adjacent to the annular groove 1131 form a complete ring, the bottom of the first inner ring 112 has poor deformation capacity. Since the connecting rib 1122 is lower than the opening of the annular groove 1131, it can effectively prevent the magnetic ring 120 from contacting the connecting rib 1122, reducing the probability of damage to the first inner ring 112 under stress.

[0052] refer to Figures 2-5 In some embodiments, the magnetic ring 120 includes a plurality of arc-shaped magnetic elements 121, each arc-shaped magnetic element 121 being configured to correspond to at least two limiting blocks 1121.

[0053] By implementing this embodiment, even if one of the limiting blocks 1121 is damaged during installation, the position of the arc-shaped magnetic component 121 can still be restricted by the other limiting block 1121, so as not to affect the installation of the arc-shaped magnetic component 121.

[0054] Specifically, the corresponding arrangement of the arc-shaped magnetic chuck 121 and the limiting block 1121 includes situations where the projection of the limiting block 1121 completely falls within the range of the arc-shaped magnetic chuck 121, and also situations where a portion of the projection of the limiting block 1121 falls within the range of the arc-shaped magnetic chuck 121. As long as two limiting blocks 1121 can be used to restrict the position of the arc-shaped magnetic chuck 121, this embodiment does not impose any limitations. For example, one half of one limiting block 1121 is directly opposite one of the arc-shaped magnetic chuck 121, and the other half is directly opposite the other arc-shaped magnetic chuck 121. In this case, the limiting block 1121 is simultaneously corresponding to both arc-shaped magnetic chuck 121s.

[0055] This utility model embodiment also provides a shooting auxiliary device 1000, such as... Figures 1-6 As shown, the shooting auxiliary device 1000 includes a main rod 200, a support frame, and a magnetic fixing base 100. The support frame is connected to the main rod 200 and is used to support the main rod 200. The magnetic fixing base 100 is the magnetic fixing base 100 shown in the above embodiment, and the magnetic fixing base 100 is connected to the main rod 200.

[0056] Specifically, the magnetic fixing base 100 includes a base body 110 and a magnetic ring 120. The base body 110 includes an outer ring 111 and a first inner ring 112. The outer ring 111 surrounds the first inner ring 112 and is spaced apart from the first inner ring 112 so that a mounting groove 113 is formed between the outer ring 111 and the first inner ring 112. The magnetic component is installed in the mounting groove 113. The first inner ring 112 includes a plurality of limiting blocks 1121, which are spaced apart in the circumferential direction of the first inner ring 112.

[0057] This embodiment demonstrates a shooting assistance device 1000 that can be erected on a table, ground, or other location using a support frame. Since the limiting blocks 1121 of the first inner ring 112 are spaced apart, the limiting blocks 1121 can better absorb energy through deformation, resulting in better toughness of the first inner ring 112 and making it less prone to damage from force.

[0058] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
