Description

Technical Field

[0001] This application relates to the field of tripod technology, and more specifically to a tripod foot spike structure. Background Technology

[0002] Since a person's arm will shake when holding an object, and the longer the time, the greater the shaking, a tripod can be used as a support to keep the object stable at a certain height.

[0003] There is a tripod foot spike structure, such as Figure 1 As shown, the tripod includes a tripod body 90 and a sleeve 91. The bottom of the tripod body 90 has a spike 901, and the sleeve 91 is threadedly connected to the spike 901. When the tripod is placed on muddy ground, the sleeve 91 is rotated upwards, so that the spike 901 is at the lowest point of the tripod body 90. When the tripod is placed on a hard, flat surface such as concrete, the sleeve 91 is unscrewed, so that the sleeve 91 is at the lowest point of the tripod body 90. However, because the sleeve 91 is threadedly connected to the tripod body 90, it takes a considerable amount of time to screw the sleeve 91 on each of the three legs of the tripod. Therefore, switching between the spike 901 and the sleeve 91 is still inconvenient.

[0004] Therefore, there is a need for a tripod foot spike structure that allows for quick switching between the spike and the sleeve. Summary of the Invention

The term is used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0027] This is an illustration of the tripod's spike structure, for reference only. Figures 2 to 5 According to a preferred embodiment of the present invention, a tripod foot spike structure includes a foot body 10, a sleeve 20 and a trigger component 30.

[0028] Specifically, the bottom of the support body 10 has a spike 101; the sleeve 20 is slidably disposed on the support body 10, exposing or blocking the spike 101; the triggering component 30 includes a pressing member 301, a first locking device 302, and a second locking device 303. The pressing member 301 is slidably disposed on the side wall of the support body 10. The first locking device 302 includes a plurality of first locking inserts 3021, and the second locking device 303 includes a plurality of second locking inserts 3031. The sleeve 20 has... There is a groove 201 that engages with the first insert 3021 or the second insert 3031. When the pressing member 301 slides, the first insert 3021 or the second insert 3031 engages or disengages from the groove 201 on the sleeve 20. When the first insert 3021 is embedded in the groove 201, the lowest point of the spike 101 is lower than the lowest point of the sleeve 20. When the second insert 3031 is embedded in the groove 201, the lowest point of the spike 101 is higher than the lowest point of the sleeve 20.

[0029] It should be noted that, assuming that the groove 201 of the sleeve 20 is engaged with the first insert 3021 at this time, exposing the spike 101, when it is necessary to switch the support body 10 to be supported by the sleeve 20, the user only needs to press the pressing member 301. Then, both the first insert 3021 and the second insert 3031 extend into the support body 10, and the position of the sleeve 20 is no longer restricted. The user can then make the sleeve 20 move along the support body. The body 10 moves downwards, aligning the groove 201 on the sleeve 20 with the second locking insert 3031. Then, the user releases the pressing member 301, causing both the first locking insert 3021 and the second locking insert 3031 to extend a predetermined distance from the side wall of the support body 10. At this point, the second locking insert 3031 engages with the groove 201 on the sleeve 20, fixing the position of the sleeve 20 and completing the switch where the sleeve 20 serves as the support. It is evident that compared to the prior art requiring multiple turns of the sleeve, the sliding sleeve in this application is faster, offering the advantage of quickly switching between the spike and the sleeve.

[0030] Furthermore, in order to quickly ensure that the groove 201 of the sleeve 20 is aligned with the first insert 3021 or the second insert 3031 when the user slides the sleeve 20, the support body 10 has a stop portion 102, and the two stop portions 102 are respectively located on opposite sides of the first insert 3021 and the second insert 3031.

[0031] It should be noted that when the sleeve 20 abuts against a lower abutment 102, the groove 201 of the sleeve 20 is directly opposite the second insert 3031, and when the sleeve 20 abuts against a higher abutment 102, the groove 201 of the sleeve 20 is directly opposite the first insert 3021.

[0032] Furthermore, to enable pressing of the pressing member 301, both the first insert 3021 and the second insert 3031 retract into the support body 10, such as... Figure 3As shown, the first locking device 302 further includes a plurality of first ropes 3022, and the second locking device 303 further includes a plurality of second ropes 3032. Each first locking insert 3021 is connected to a first rope 3022 at one end near the central axis of the support body 10, and each second locking insert 3031 is connected to a second rope 3032 at one end near the central axis of the support body 10. The triggering component 30 further includes a lifting member 304. The lifting member 304 is slidably disposed on the lifting member 304 along the axial direction of the support body 10. One end of the lifting member 304 abuts against the first ropes 3022 and the second ropes 3032, and the other end of the lifting member 304 has a first inclined surface 3041. The end of the pressing member 301 that extends into the support body 10 has a second inclined surface 3011, and the first inclined surface 3041 and the second inclined surface 3011 are in contact.

[0033] In addition, such as Figure 3 and Figure 4 As shown, the lifting component 304 includes a block 3042, a first column 3043 or several second columns 3044. The second columns 3044 are arranged in a ring array around the first column 3043. The length of the second column 3044 is greater than the length of the first column 3043. One end of both the first column 3043 and the second column 3044 is connected to the block 3042. The connection method includes, but is not limited to, welding. The first inclined surface 3041 is located at the end of the block 3042 away from the first column 3043. The first locking device 302 further includes a first connector 3023. The second locking device 303 further includes a second connector 3033. The sidewall of the first connector 3023 is connected to each of the first ropes 3022. The sidewall of the second connector 3033 is connected to each of the second ropes 3032. The first column 3043 abuts against the first connector 3023. The second column 3044 abuts against the second connector 3033.

[0034] In addition, such as Figure 4As shown, the support body 10 has a plurality of first receiving holes 103, a plurality of second receiving holes 104, a vertical cavity 105, and a horizontal cavity 106. The first receiving holes 103 and the second receiving holes 104 are both located on the side of the support body 10. The vertical cavity 105 is located inside the support body 10, and the central axis of the vertical cavity 105 coincides with the central axis of the support body 10. The horizontal cavity 106 extends from the side wall of the support body 10 towards the central axis of the support body 10 and communicates with the vertical cavity 105. The vertical cavity 105 communicates with each of the first receiving holes 103 and each of the second receiving holes 104. The second receiving hole 104 is connected, the first insert 3021 is slidably disposed in the first receiving hole 103, the second insert 3031 is slidably disposed in the second receiving hole 104, the lifting member 304 is lifted and lowered in the vertical cavity 105, the pressing member 301 is slidably disposed in the horizontal cavity 106, the end of the first rope 3022 facing away from the first insert 3021 extends into the vertical cavity 105 and is connected to the first connector 3023, the end of the second rope 3032 facing away from the second insert 3031 extends into the vertical cavity 105 and is connected to the second connector 3033.

[0035] It is readily apparent that when the pressing member 301 is pressed, the second inclined surface 3011 on the pressing member 301 applies a downward force to the first inclined surface 3041 on the lifting member 304, causing the lifting member 304 to move downward a predetermined distance. Then, the first column 3043 applies a downward pressure to the first connecting member 3023, and the second column 3044 applies a downward pressure to the second connecting member 3033. As the first connecting member 3023 moves downward, the first rope 3022 drives the first locking member 3021 to move into the first receiving hole 103. As the second connecting member 3033 moves downward, the second rope 3032 drives the second locking member 3031 to move into the second receiving hole 104. This allows the sleeve 20 to slide up and down between the two abutment portions 102 when the pressing member 301 is pressed.

[0036] In addition, to ensure that the pressing member 301 springs back to its initial position after being released, the first locking member 3021 and the second locking member 3031 extend back out of the openings of the first receiving hole 103 and the second receiving hole 104 by a predetermined distance, such as... Figure 4 and Figure 5As shown, both the first receiving hole 103 and the second receiving hole 104 are stepped holes. The triggering component 30 also includes a plurality of first elastic elements 305 and a second elastic element 306. Each of the first receiving holes 103 and the second receiving holes 104 is provided with a first elastic element 305. One end of the first elastic element 305 abuts against the first insert 3021 or the second insert 3031, and the other end of the first elastic element 305 abuts against the bottom wall of the larger cavity of the first receiving hole 103 or the second receiving hole 104. The bottom of the vertical cavity 105 is provided with a second elastic element 306, and both ends of the second elastic element 306 abut against the bottom of the second connector 3033 and the bottom wall of the vertical cavity 105, respectively.

[0037] It should also be added that, in order to realize that the sleeve 20 is fitted between the two abutting parts 102, the sleeve 20 can be made by two half sleeves respectively attached to the support body 10, and then the two half sleeves are spliced ​​together by welding to form a whole sleeve 20.

[0038] In summary, the tripod foot spike structure based on the embodiments of this application has been clarified, which provides advantages such as the ability to quickly switch between spikes and sleeves.

[0039] It is worth mentioning that, in this embodiment, the tripod's foot spike structure is simple, does not involve complex manufacturing processes or expensive materials, and is highly economical. Furthermore, for manufacturers, the tripod's foot spike structure provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
