Detailed Implementation

[0016] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0017] like Figure 1-2As shown, a rotatable base includes a lower housing 1, a first rotating body 2 rotatably mounted on the lower housing 1, a first rotating body drive unit 3 for driving the first rotating body 2 to rotate, a second rotating body 4 rotatably mounted on the lower housing 1 and disposed on the first rotating body 2, a second rotating body drive unit 5 for driving the second rotating body 4 to rotate, and an upper housing 6 rotatably mounted above the second rotating body drive unit 5.

[0018] This application provides a rotatable base. By arranging a first rotating body 2 and a second rotating body 4 nested in the inner cavities of the upper and lower housings of the base, two independent methods for adjusting the rotational position of the upper housing 6 are provided. The nested structure of the first rotating body 2 and the second rotating body 4 is designed so that the rotational position of the second rotating body 4 can be adjusted synchronously when the rotational position of the first rotating body 2 is adjusted, thereby causing the rotational position of the upper housing 6 to be adjusted as well. This application does not impose many other limitations on the nested structure of the first rotating body 2 and the second rotating body 4. Those skilled in the art, based on the specific embodiments provided in this application, should make improvements through modifications, alterations, equivalent substitutions, etc., all of which should fall within the protection scope of this application.

[0019] This application describes two independent adjustment methods for the rotational position of the housing 6 on the base through the configuration of the first rotating body 2 and the second rotating body 4. However, this application does not impose excessive restrictions on the two independent adjustment methods or functional requirements. For example, one of the first rotating body 2 and the second rotating body 4 can provide a coarse adjustment function, while the other provides a fine adjustment function; or one of the first rotating body 2 and the second rotating body 4 can be adjusted by a manual knob, while the other can be adjusted by an automatic control device such as a motor. Depending on the usage scenario, the first rotating body 2 and the second rotating body 4 can be given different functions for independently adjusting the rotation position and corresponding mechanical structures.

[0020] In various embodiments of the adjustable base provided in this application, it is preferable that the lower housing 1 of the base is configured with a first rotating body drive mounting seat for mounting the first rotating body drive unit 3, the first rotating body 2 is configured with a first rotating body transmission engagement part 21, and the first rotating body drive unit 3 includes a first transmission part 31 that engages with the first rotating body transmission engagement part 21, and a first adjustment part 32 configured outside the lower housing 1 of the base.

[0021] This application provides a first rotating body drive unit 3 installed on the lower housing 1 of the base. It is connected to the first rotating body 2 via a first transmission unit 31 and a first rotating body transmission engagement unit 21. The rotational position of the first rotating body 2 can be adjusted by adjusting the first adjustment unit 32 located outside the lower housing 1 of the base.

[0022] The transmission method between the first rotating body 2 and the first rotating body drive unit 3 provided in this application is a ring gear ring and threaded engagement. Those skilled in the art can use worm gears, bevel gear pairs, belts, chains, ring gears, etc. for transmission, and these should be within the scope of protection of this application.

[0023] The first rotating body transmission mating part 21 provided in this application is disposed on the outer periphery of the first rotating body 2, and has good fine-tuning function and is stable and reliable. Specifically, in the specific embodiment, the first rotating body transmission mating part 21 is located on the longitudinal annular surface of the outer periphery of the first rotating body 2. In addition, based on the ideas of those skilled in the art, or adopting the technical solutions disclosed by the applicant in earlier patents, the first rotating body transmission mating part 21 may adopt an annular spline or rack arranged circumferentially on the outer side of the upper or lower surface of the first rotating body 2, and the first rotating body drive part 3 may adopt a thread that mates with it, etc., all of which should be within the protection scope of this application.

[0024] In various embodiments of the adjustable base provided in this application, it is preferable that the upper housing 6 of the base is provided with a second rotating body drive unit mounting seat for mounting the second rotating body drive unit 5, the outer periphery of the second rotating body 4 is provided with a second rotating body transmission mating part 41, and the second rotating body drive unit 5 includes a second transmission part 51 that mates with the second rotating body transmission mating part 41, and a second adjustment part 52 mounted on the second rotating body drive unit mounting seat.

[0025] Specifically, this application provides a second rotating body drive unit 5 installed on the housing 6 of the base. It is driven by a second rotating body drive engagement unit 41 configured with a second rotating body 4 through a second transmission unit 51. The rotational position of the second rotating body 4 can be adjusted by adjusting the second adjustment unit 52 of the mounting base of the second rotating body drive unit.

[0026] The transmission method between the second rotating body 4 and the second rotating body drive unit 5 provided in this application is a ring gear and gear engagement. Other transmission methods can be used by those skilled in the art, as described above, and these should be within the scope of protection of this application.

[0027] Furthermore, this application provides a specific embodiment in which the second rotating body drive unit 5 is a micro motor, the second transmission unit 51 is the drive end of the micro motor, and the second adjustment unit 52 is the stationary end of the micro motor and its control mechanism. That is, in the specific embodiment provided by this application, the second rotating body 4 and the second rotating body drive unit 5 are driven by a motor, providing an intelligent rotational position adjustment method. This application does not impose many limitations on the structure or technical solution of the second rotating body drive unit 5. For example, within the scope of this application, the second transmission unit 51 of the second rotating body drive unit 5 can be a gear, and the second adjustment unit 52 can be a motor (including a motor drive end) that drives the gear. The motor drive end drives the second rotating body 4 through one or more gears or other means; these also fall within the protection scope of this application.

[0028] In various embodiments of the adjustable base provided in this application, it is preferable that the lower housing 1 of the base is provided with a first mounting shaft 12, and the inner circumference of the first rotating body 2 is provided with a first mounting hole 22 for fitting the first mounting shaft 12.

[0029] This application provides an insertion and mating method between the lower housing 1 of the base and the first rotating body 2, which can also serve as a rotating shaft.

[0030] In various embodiments of the adjustable base provided in this application, the lower housing 1 of the base is configured with a longitudinal limiting part for longitudinally limiting the first rotating body 2. The number of longitudinal limiting parts is not limited; this embodiment provides two longitudinal limiting parts (first longitudinal limiting part 13, second longitudinal limiting part 14) at the following positions. However, this application does not limit their position, number, or structure.

[0031] The lower housing 1 of the base also includes a first longitudinal limiting portion 13 for longitudinally limiting the inner periphery of the first rotating body 2. Further, in an embodiment having a first mounting shaft 12, the first longitudinal limiting portion 13 may be disposed below the first mounting shaft 12. The first longitudinal limiting portion 13 disposed on the inner periphery of the lower housing 1 of the base provides stable rotation of the first rotating body 2.

[0032] In various embodiments of the adjustable base provided in this application, the lower housing 1 of the base preferably includes a second longitudinal limiting portion 14 for longitudinally limiting the outer periphery of the first rotating body 2. In the specific embodiments provided in this application, the second longitudinal limiting portion 14 located on the outer periphery of the first longitudinal limiting portion 13 is arranged on the outer periphery of the lower housing 1 of the base to provide stable rotation of the first rotating body 2.

[0033] The specific implementation provided in this application is a case where both the first longitudinal limiting part 13 and the second longitudinal limiting part 14 exist. Of course, the purpose of this application can also be achieved by using only the first longitudinal limiting part 13 or only the second longitudinal limiting part 14, and these should also fall within the protection scope of this application.

[0034] In various embodiments of the adjustable base provided in this application, it is preferable that the first rotating body 2 is provided with a first circumferential limiting insert 23, the second rotating body 4 is provided with a second circumferential limiting insert 43 that is inserted and cooperates with the first circumferential limiting insert 23, the first rotating body 2 is provided with a third longitudinal limiting insert 24 for longitudinally limiting the second circumferential limiting insert 43 and / or the second rotating body 4 is provided with a fourth longitudinal limiting insert 42 for longitudinally limiting the first circumferential limiting insert 23.

[0035] This application provides a method in which the first rotating body 2 and the second rotating body 4 can be rotatably installed relative to each other. The insertion of the first circumferential limiting insert 23 and the second circumferential limiting insert 43 allows the first rotating body 2 and the second rotating body 4 to rotate coaxially. The third longitudinal limiting part 24 for limiting the first rotating body 2 or the fourth longitudinal limiting part 42 for limiting the second rotating body 4 further or independently provides smooth rotation between the first rotating body 2 and the second rotating body 4.

[0036] Furthermore, the first circumferential limiting insert 23 configured on the first rotating body 2 should preferably be coaxially arranged with the first mounting shaft 12. This provides better stability and operability.

[0037] The first rotating body 2 is configured with a third longitudinal limiting part 24 for longitudinally limiting the second circumferential limiting insert part 43 and / or the second rotating body 4 is configured with a fourth longitudinal limiting part 42 for longitudinally limiting the first circumferential limiting insert part 23.

[0038] There are different interpretations here: If the third longitudinal limiting part 24 and the fourth longitudinal limiting part 42 are considered to be a pair of mutually cooperating limiting parts, then "and" must be used here; if the third longitudinal limiting part 24 and the fourth longitudinal limiting part 42 are considered not to be a pair of mutually cooperating limiting parts, but rather to be independent and each playing a longitudinal limiting role in different positions, then "and" and "or" (either one) can both fulfill the applicant's inventive intent here. The embodiment adopted in this application is that the third longitudinal limiting part 24 located in the inner circumference and the fourth longitudinal limiting part 42 located in the outer circumference coexist and each has an independent cooperating part, which has better stability.

[0039] In various embodiments of the adjustable base provided in this application, it is preferable that the second rotating body 4 is configured with a second circumferential limiting insert 43, and the upper housing 6 of the base is configured with a third circumferential limiting insert 63 that is inserted and cooperates with the second circumferential limiting insert 43.

[0040] This application provides a method in which the second rotating body 4 and the upper housing 6 of the base can be rotated relative to each other.

[0041] Furthermore, the second circumferential limiting insert 43 configured on the second rotating body 4 should preferably be coaxially arranged with the first mounting shaft 12.

[0042] The second rotating body 4, which is inserted into the second limiting insertion part 43 and the third limiting insertion part 63, rotates coaxially with the upper housing 6 of the base.

[0043] This application does not limit the position or number of longitudinal limiting points on the housing 6 of the base. Depending on different structural designs, there can be one or two longitudinal limiting points on the second rotating body 4, or other solutions. This application provides the following embodiment: a sixth longitudinal limiting part 25 located on the inner periphery and a fifth longitudinal limiting part 64 located on the outer periphery. The sixth longitudinal limiting part 25 is provided by the first rotating body 2, and the fifth longitudinal limiting part 64 is provided by the second rotating body, resulting in better stability. The fifth longitudinal limiting part 64 and the sixth longitudinal limiting part 25 can be configured independently. The specific implementation provided in this application combines both. This results in better stability.

[0044] In various embodiments of the adjustable base provided in this application, it is preferable that the second rotating body 4 is configured with a fifth longitudinal limiting part 44 for longitudinally limiting the upper housing 6 of the base, and the upper housing 6 of the base is configured with an opposing fifth longitudinal limiting part 64 that cooperates with the fifth longitudinal limiting part 44.

[0045] The sliding engagement between the fifth longitudinal limiting part 44 of the second rotating body 4 and the opposing fifth longitudinal limiting part 64 of the upper housing 6 of the base provides smooth rotation between the second rotating body 4 and the upper housing 6 of the base.

[0046] In various embodiments of the adjustable base provided in this application, it is preferable that the first rotating body 2 is configured with a sixth longitudinal limiting part 25 for longitudinally limiting the third circumferential limiting insert 63 of the upper housing 6 of the base.

[0047] The sixth longitudinal limiting part 25 of the first rotating body 2 provided in this application further or independently provides a longitudinal limiting base upper housing 6 for smooth rotation between the first rotating body 2 and the first rotating body 2.

[0048] This application provides numerous independent and interchangeable insertion methods or longitudinal limiting points, which are examples provided by the applicant to ensure smooth rotation. These should not be construed as limiting the scope of protection of this application. Those skilled in the art, based on the concepts provided in the embodiments, may employ other structures for the first or second rotating body, and these should also be covered within the scope of protection of this application. To enhance smooth rotation among components such as the lower housing of the base, the first rotating body, the second rotating body, and the upper housing of the base, damping oil can also be applied to the insertion or limiting mating parts.

[0049] As in the embodiments provided in this application, the first rotating body, the second rotating body, and the upper housing 6 of the base all have cylindrical structures. The first rotating body is fitted with the first mounting shaft 12 of the lower housing 1 of the base, the second rotating body is inserted into the first rotating body, and the upper housing 6 of the base is then inserted into the second rotating body. Other fitting arrangements are possible within the scope of those skilled in the art, such as the first rotating body being in the middle, and the second rotating body and the upper housing 6 of the base being respectively inserted into both sides of the first rotating body. These should all fall within the protection scope of this application.

[0050] This utility model also provides an instrument, including the adjustable base of any of the above, and a rangefinder, a line marker, and a level disposed on the adjustable base.

[0051] The adjustable base provided in this application has a wide range of applications and can be used as a base for various devices or instruments, providing them with adjustable rotational positions.
