Description

Technical Field

[0001] This utility model relates to the field of gimbal accessories technology, and in particular to a gimbal clamp and a gimbal. Background Technology

[0002] A gimbal is a device used to fix equipment and adjust the direction in which the equipment is pointing. It is often used in situations where high accuracy of pointing of the equipment is required, such as for fixing photographic equipment and telescopes. In order to hold or equip different equipment, the top of the gimbal is often equipped with a gimbal clamp with adjustable spacing.

[0003] Existing gimbal clamps, such as the gimbal connection disclosed in publication number CN217383977U, generally include two clamping plates. One clamping plate is fixed to a base for connecting with a bracket, while the other clamping plate is adjustable and threadedly connected to a screw on the base. Rotating the screw moves the two clamping plates closer or further apart to clamp the device or adjust the spacing. However, since only one clamping plate is movable while the other is fixed, the midpoint of the line connecting the two clamping plates moves with the movement of one clamping plate, causing the device's orientation to shift. This requires a corresponding readjustment of the bracket's position, making the operation inconvenient. Furthermore, the adjustment of the clamping plate spacing depends entirely on the movement of one clamping plate. When the spacing adjustment requirement is large, the screw needs to be rotated many times, resulting in low adjustment efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the technical problems of existing gimbal clamps that use a structure where one side clamp is fixed and the other side clamp is adjustable, which causes the device to deviate when adjusting the position of the clamp and has low spacing adjustment efficiency, and to provide a gimbal clamp and gimbal.

[0005] In a first aspect, the present invention provides a gimbal clamp, comprising:

[0006] Base;

[0007] The first clamping plate and the second clamping plate are slidably connected to the base. The first clamping plate and the second clamping plate can move closer to each other or further away from each other. The first clamping plate is provided with a left-hand threaded hole, and the second clamping plate is provided with a right-hand threaded hole.

[0008] The adjusting rod is rotatably connected to the base. Along the length of the adjusting rod, there are left-hand threaded sections and right-hand threaded sections. The left-hand threaded sections are threaded to the left-hand threaded holes, and the right-hand threaded sections are threaded to the right-hand threaded holes.

[0009] The gimbal clamp of this design allows both the first and second clamping plates to slide on the base and be threaded to the left-hand and right-hand threaded sections of the adjusting rod, respectively. When it is necessary to adjust the distance between the first and second clamping plates, rotating the adjusting rod in one direction will cause the first and second clamping plates to move simultaneously along the length of the adjusting rod. Since the left-hand and right-hand threaded sections have opposite directions of rotation, the first and second clamping plates move closer to or further away from each other, thus enabling them to be used for clamping equipment or adjusting the distance.

[0010] As can be seen from the above, in this solution, the first and second clamping plates can move synchronously with the rotation of the adjusting rod. Therefore, the midpoint of the line connecting the first and second clamping plates can always remain unchanged relative to the base. This ensures that the orientation of the device clamped in this solution will not shift due to the adjustment of the distance between the first and second clamping plates. Compared with the prior art, this solution better guarantees the coaxiality of the device orientation with the bracket position and eliminates the need to readjust the bracket position after each adjustment, making it more convenient to use. Furthermore, in this solution, rotating the adjusting rod allows both the first and second clamping plates to move along the adjusting rod. With the same adjustment distance, this solution can reduce the number of rotations of the adjusting rod, resulting in higher adjustment efficiency.

[0011] Preferably, both the first and second clamping plates are composed of at least two segments joined together, and the joint between two adjacent segments passes through a left-hand threaded hole or a right-hand threaded hole.

[0012] This solution facilitates the installation of the first and second clamping plates. For example, if there are two sections, the two sections can be surrounded by the adjusting rod from both sides, and then the two sections can be combined to form the first or second clamping plate. Thus, without disassembling the adjusting rod, the first or second clamping plate can be threadedly connected to the adjusting rod, which allows for quick and easy replacement of the corresponding first and second clamping plates according to different equipment.

[0013] Preferably, two adjacent segments are connected by a threaded connector.

[0014] This solution recommends one specific detachable connection method between segments, which can ensure reliable connection between two adjacent segments and avoid accidental separation of two adjacent segments, which could lead to the disintegration or detachment of the first or second clamping plate, and consequently cause the equipment to fall.

[0015] Preferably, a guide rod is provided on the base, and guide holes are provided on both the first clamping plate and the second clamping plate, with the guide rod slidably connected to the guide holes.

[0016] This solution recommends a specific sliding connection method between the first and second clamping plates and the base. On the one hand, the sliding connection between the guide rod and the guide hole can induce the first and second clamping plates to move closer or further apart more smoothly, avoiding the situation where the first and second clamping plates are stuck relative to the base. On the other hand, it can also share the load with the base and the adjusting rod, and limit the movement of the first and second clamping plates, thereby suppressing the tilting or deformation of the first and second clamping plates due to the equipment load, thus ensuring the clamping effect of the first and second clamping plates on the equipment, as well as the robustness and service life of this solution.

[0017] Preferably, there are at least two guide rods, which are distributed on both sides of the adjusting rod.

[0018] This solution can further improve the guiding and limiting effect of the guide rod on the first and second clamping plates.

[0019] Preferably, both the first clamping plate and the second clamping plate are provided with a limiting boss at one end near the base. The limiting boss on the first clamping plate protrudes towards the second clamping plate, and the limiting boss on the second clamping plate protrudes towards the first clamping plate. At least one side of the limiting boss, parallel to the length direction of the adjusting rod, can abut against the base.

[0020] This solution increases the contact area between the first and second clamping plates and the base by using limiting bosses, thereby improving the load transfer capacity and limiting effect between the first and second clamping plates and the base, thus suppressing the tilting or deformation of the first and second clamping plates due to equipment load, and ensuring the clamping effect of the first and second clamping plates on the equipment, as well as the robustness and service life of this solution.

[0021] Preferably, at least one end of the adjusting rod is connected to an adjusting handle.

[0022] This design allows operators to more easily rotate the adjusting lever.

[0023] Preferably, a limit stop is provided at one end of the adjusting rod, and the adjusting handle is detachably connected to the other end of the adjusting rod.

[0024] This solution can limit the two ends of the adjusting rod through the limit stop and the adjusting handle, thereby preventing the adjusting rod from slipping out of the base.

[0025] Preferably, one side of the base is provided with a threaded hole for connecting to the bracket.

[0026] This solution recommends one specific method for connecting the base and the bracket.

[0027] In a second aspect, the present invention provides a gimbal, including a bracket, on which a gimbal clamp of the present invention is connected.

[0028] The gimbal in this design is connected to the gimbal clamp of this invention on the bracket. When adjusting the distance between the first clamp and the second clamp, the first clamp and the second clamp can move synchronously and symmetrically. On the one hand, this ensures that the position of the clamped device relative to the bracket remains unchanged, thereby ensuring the coaxiality of the device with the bracket. On the other hand, it can increase the change value of the distance between the first clamp and the second clamp while the adjustment rod rotates the same number of times, thus having higher adjustment efficiency.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] 1. This utility model provides a gimbal clamp, in which a first clamping plate and a second clamping plate are slidably connected to a base and respectively threaded to a left-hand threaded section and a right-hand threaded section on an adjusting rod. When it is necessary to adjust the distance between the first clamping plate and the second clamping plate, rotating the adjusting rod in one direction will cause the first clamping plate and the second clamping plate to move simultaneously along the length of the adjusting rod, thereby moving them closer or further apart. Furthermore, this solution ensures that the orientation of the clamped device will not shift due to the movement of the first clamping plate and the second clamping plate, thus better guaranteeing the coaxiality of the device's orientation with the support position compared to existing technologies. It also eliminates the need to readjust the support position after each adjustment, making it more convenient to use. Moreover, in this solution, rotating the adjusting rod causes both the first clamping plate and the second clamping plate to move along the adjusting rod. With the same adjustment distance, this solution reduces the number of rotations of the adjusting rod, resulting in higher adjustment efficiency.

[0031] 2. This utility model provides a gimbal. By connecting the gimbal clamp of this utility model to the bracket, when adjusting the distance between the first clamp and the second clamp, the first clamp and the second clamp can move synchronously and symmetrically. On the one hand, it can ensure that the position of the clamped device relative to the bracket remains unchanged, thereby ensuring the coaxiality of the device and the bracket; on the other hand, it can increase the change value of the distance between the first clamp and the second clamp while the adjustment rod rotates the same number of times, thus having higher adjustment efficiency.

[0045] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0046] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0047] Furthermore, the use of terms such as "horizontal," "vertical," "suspension," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspension," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0048] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0051] Example 1

[0052] like Figures 1 to 9As shown, a gimbal clamp includes a base 1, a first clamping plate 21, a second clamping plate 22, and an adjusting rod 3. Both the first clamping plate 21 and the second clamping plate 22 are slidably connected to the base 1, and can move closer or further apart. The first clamping plate 21 has a left-hand threaded hole, and the second clamping plate 22 has a right-hand threaded hole. The adjusting rod 3 is rotatably connected to the base 1, and along its length, a left-hand threaded section 31 and a right-hand threaded section 32 are sequentially provided on the adjusting rod 3. The left-hand threaded section 31 is threaded to the left-hand threaded hole, and the right-hand threaded section 32 is threaded to the right-hand threaded hole. Rotating the adjusting rod 3 allows the first clamping plate 21 and the second clamping plate 22 to move closer or further apart, for clamping photographic equipment, binoculars, firearms, and other devices.

[0053] In the above embodiments, the sliding connection between the first clamping plate 21 and the second clamping plate 22 and the base 1 can be achieved by various mechanisms, including but not limited to a guide rail mechanism, pulleys, and sliding bearings provided between the first clamping plate 21 and the second clamping plate 22 and the base 1 respectively.

[0054] In optional implementations, such as Figure 9 As shown, the base 1 includes two limiting grooves 14 spaced apart along the length of the adjusting rod 3. The lower ends of the first clamping plate 21 and the second clamping plate 22 are respectively located within the two limiting grooves 14; the width of the limiting groove 14, i.e., its length along the... Figure 9 The vertical dimension matches the width of the first clamping plate 21 and the second clamping plate 22, and the length of the limiting groove 14, i.e., its length along... Figure 9 The dimension in the left-right direction is greater than the length of the first clamping plate 21 and the second clamping plate 22, so that the first clamping plate 21 and the second clamping plate 22 can move along... Figure 9 It moves in the left and right directions.

[0055] In an optional embodiment, the width of the limiting groove 14 is 38mm and the length of the limiting groove 14 is greater than or equal to 50mm, so that the base 1 can be adapted to a firearm quick-release plate with a width of 38mm and any length, thus being particularly suitable for the clamping and fixing of firearms.

[0056] In an optional embodiment, both the first clamping plate 21 and the second clamping plate 22 are composed of at least two segments 201 joined together, and the joint between two adjacent segments 201 passes through a left-hand threaded hole or a right-hand threaded hole. For example Figure 6As shown, taking the second clamping plate 22 as an example, it includes two segments 201 that can be separated in the vertical direction. The line connecting the joint of the two segments 201 passes through the center of the right-hand threaded hole, meaning that each segment 201 contains half of a right-hand threaded hole. When the two segments 201 are connected to each other, they can form a complete right-hand threaded hole. Therefore, when installing the second clamping plate 22, the two segments 201 can be placed on the upper and lower sides of the adjusting rod 3 respectively, and then the two segments 201 can be joined together to surround the adjusting rod 3. The connection methods between two adjacent segments 201 include, but are not limited to, threaded connection, snap-fit ​​connection, and tenon and mortise connection. The number of segments 201 depends on the actual needs and can be two or more.

[0057] In an optional implementation, two adjacent segments 201 are connected by a threaded connector. For example... Figure 6 As shown, the two segments 201 of the second clamping plate 22 are connected by screws.

[0058] In an optional embodiment, a guide rod 11 is provided on the base 1, and the axis of the guide rod 11 is parallel to the axis of the adjusting rod 3; a guide hole 202 is provided on both the first clamping plate 21 and the second clamping plate 22, and the guide rod 11 is slidably connected to the guide hole 202.

[0059] In optional implementations, such as Figure 6 As shown, the guide rod 11 has a circular cross-sectional shape, which ensures that the guide rod 11 has a good guiding effect and load-bearing capacity; correspondingly, the guide hole 202 also has a circular cross-sectional shape.

[0060] In an optional embodiment, the number of guide rods 11 is at least two, and the guide rods 11 are distributed on both sides of the adjusting rod 3. For example Figure 2 and Figure 6 As shown, at least one guide rod 11 is provided on each of the left and right sides of the adjusting rod 3, so as to fully suppress the left and right tilting and front and back tilting of the first clamping plate 21 or the second clamping plate 22.

[0061] In an optional embodiment, both the first clamping plate 21 and the second clamping plate 22 are provided with limiting bosses 203 at their ends near the base 1. The limiting bosses 203 on the first clamping plate 21 protrude towards the second clamping plate 22, and the limiting bosses 203 on the second clamping plate 22 protrude towards the first clamping plate 21. At least one side of the limiting bosses 203, parallel to the length direction of the adjusting rod 3, can abut against the base 1. For example... Figure 7As shown, limiting protrusions are provided on the right side of the lower end of the first clamping plate 21 and the left side of the lower end of the second clamping plate 22, so that the cross-sectional shape of the first clamping plate 21 and the second clamping plate 22 is approximately "L" shaped. This increases the contact area between the first clamping plate 21 and the second clamping plate 22 and the guide rod 11, and also increases the contact area between the first clamping plate 21 and the second clamping plate 22 and the base 1. Correspondingly, limiting bottom plates 12 extending towards the first clamping plate 21 and the second clamping plate 22 are provided at the bottom of the base 1. The limiting bottom plates 12 can abut against the bottom surface of the limiting protrusion 203, thereby providing additional support for the first clamping plate 21 and the second clamping plate 22. In addition, as shown in the figure... Figure 5 As shown, the left and right sides of the limiting boss 203 can also abut against the corresponding sides of the base 1, thereby further improving the stability of the connection between the first clamping plate 21 and the second clamping plate 22 and the base 1.

[0062] In an optional embodiment, at least one end of the adjusting rod 3 is connected to an adjusting handle 4; the maximum diameter of the adjusting handle 4 along the radial direction of the adjusting rod 3 can be greater than the diameter of the adjusting rod 3, thereby enabling the operator to rotate the adjusting rod 3 with less effort.

[0063] In an optional embodiment, the adjusting handle 4 includes at least two arc-shaped protrusions, which are spaced apart tangentially along the adjusting rod 3, for example... Figure 8 As shown, the adjustment handle 4 includes three arc-shaped protrusions spaced 120° apart to facilitate the operator's application of force.

[0064] In an optional embodiment, the surface of the adjustment handle 4 is provided with anti-slip protrusions.

[0065] In an optional embodiment, a limiting stop 33 is provided at one end of the adjusting rod 3, and the adjusting handle 4 is detachably connected to the other end of the adjusting rod 3. The specific structural form of the limiting stop 33 includes, but is not limited to, a stop block, a stepped shaft, and a retaining ring; the detachable connection between the adjusting handle 4 and the adjusting rod 3 includes, but is not limited to, threaded connection, snap-fit ​​connection, and tenon-mortise connection.

[0066] In an optional embodiment, one side of the base 1 is provided with a threaded hole 13 for connecting to a bracket. For example... Figure 4 and Figure 8 As shown, the bottom surface of the base 1 is provided with two threaded holes 13.

[0067] Example 2

[0068] A gimbal includes a bracket on which a gimbal clamp as described in Embodiment 1 is connected.

[0069] In an optional implementation, the support is a tripod.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
