Description

Support base

The present invention relates to a support seat, and particularly relates to a support seat for supporting objects.

In daily life, photographic lenses are often used for long-term photography, such as surveillance lenses or webcams. Since this type of monitor must maintain a fixed shooting angle for a long time, a support frame is usually used to support and fix the shooting angle of the lens. The conventional lens support frame usually has a long groove or an arc-shaped groove on the frame body, and the position of the lens relative to the frame body is fixed by a screw lock method. Usually, when you want to change the camera angle of the lens, you need to remove the screw first, adjust the position of the lens on the frame, and then use the bolt to tighten the lens and position it.

However, this architecture has the following problems:

1. The user needs to use hand tools, such as a screwdriver, to loosen and tighten the bolts to adjust the lens. Therefore, for the user, the lens angle adjustment is not very convenient and can be easily achieved.

2. After the user loosens the bolt, the lens is in a free state relative to the support frame. The user must hold the lens whose angle has been adjusted with one hand, and try to tighten the bolt with the other hand. Often after the bolt is tightened, the previously adjusted angle It's not the same anymore.

3. Since the bolts used to locate the lens may rust due to long periods of unscrewing, it is not easy to loosen, which increases the difficulty of adjusting the lens.

Fourth, the bolts may gradually loosen due to vibration and other factors, causing the camera angle of the lens to change.

The invention provides a support seat which is convenient to adjust the angle.

FIG. 1 is an exploded schematic diagram of a support base of an embodiment of the present invention, and FIG. 2 is an assembly schematic view of the support base of FIG. 1. Please refer to FIG. 1 and FIG. 2 at the same time. The support base 100 of this embodiment is used to support an object, and the object may be a surveillance camera or a network camera, but is not limited to this.

The supporting base 100 includes a base 110, a limiting base 120, a fixing base 130, a supporting column 140, a sliding rail 150, an elastic element 160 and a ball shaft 170. The base 110 may be made of metal or plastic. The base 110 is used to be fixed to a reference surface (not shown). The reference surface may be a desktop or a wall, depending on actual needs.

The material of the limiting base 120 and the fixing base 130 can be selected from plastic or metal according to requirements. The fixing base 130 is connected to the base 110 and the limiting base 120 and is located between the base 110 and the limiting base 120. The fixing base 130 may be connected to the base 110 in a screw lock manner, and the fixing base 130 has a plurality of hooks 132, and the limit base 120 has an inner ring 122, and the hooks 132 can extend into the limit base 120 and Snap with the inner ring 122. The fixing base 130 is in the shape of a sleeve, and it has an inner sliding rail 134 (as shown in FIG. 3). In the case where the fixing base 130 is made of plastic, the inner sliding rail 134 can be made by injection molding; When the fixing base 130 is made of metal, a post-processing method such as scraping may be used to form the inner slide rail 134 in the fixing base 130. In one embodiment, it is also possible to use a two-material injection method to form the fixing base 130, in which the main body of the fixing base 130 is formed of metal, and then the inner slide rail structure in the main body of the fixing base 130 is formed of plastic.

The support column 140 is disposed between the base 110 and the limit seat 120, and the support column 140 has a column portion 142 and a lower rail portion 144 surrounding the column portion 142. The material of the support column 140 can also be selected from plastic or metal. It should be noted that the lower rail portion 144 is located in the middle of the columnar portion 142, not at the end of the columnar portion 142.

The sliding rail 150 is disposed in the fixed base 130 and can move, rotate or stop relative to the fixed base 130 by cooperating with the structure of the inner sliding rail 134. The sliding rail 150 has an upper sliding rail portion 152, and the upper sliding rail portion 152 and the lower rail portion 144 are in contact with each other. The slide rail 150 is usually made of the same material as the fixed seat 130 (or inner slide rail structure). This is because the slide rail 150 will contact the inner slide 134 of the fixed seat 130 and produce relative movement or rotation. The same material is selected. The material can prevent large abrasion due to the different materials during operation.

The elastic element 160 may be a spring, which is made of metal, and abuts against the base 110 and the sliding rail 150. Specifically, one end of the elastic element 160 abuts against the base 110 and the other end abuts against the slide rail 150.

The ball shaft 170 can be made of metal or plastic. The ball shaft 170 has a ball portion 172 and a shaft portion 174. The ball portion 172 is limited in the limiting seat 120, the supporting column 140 abuts the ball portion 172, and the shaft portion 174 protrudes outside the limiting seat 120. In addition, one end of the shaft portion 174 away from the ball portion 172 has an external thread 174a for screw locking with the object.

FIG. 3 is a schematic cross-sectional view of the fixing base 130. Please refer to FIGS. 1, 2 and 3 at the same time. The outer circumference of the slide rail 150 has a plurality of ribs 154, and the inner slide 134 has a first rail 134a, a second rail 134b, and a third rail 134c. The guide rail 134b is connected between the first guide rail 134a and the third guide rail 134c, and when the sliding rail 150 moves and rotates relative to the fixed base 130, the rib 154 is locked into the first guide rail 134a or the third guide rail 134c. The rib 154 moves between the first guide rail 134a or the third guide rail 134c and is guided by the second guide rail 134b.

It can be seen from FIG. 3 that any two adjacent first rails 134a and third rails 134c are connected by a second rail 134b, wherein along the radial direction of the fixing seat 130, the depth of the first rail 134a is greater than that of the third rail 134a. The depth of the guide rail 134c, the depth of the third guide rail 134c is greater than the depth of the second guide rail 134b. In other words, the wall thickness of the fixing seat 130 where the first guide rail 134a is provided is smaller than the wall thickness of the fixing seat 130 where the third guide rail 134c is provided is smaller than the wall thickness of the fixing seat 130 where the second guide rail 134b is provided.

Please continue to refer to FIG. 1, FIG. 2 and FIG. 3. In the fixed state of the ball shaft 170 as shown in FIG. 2, the rib 154 is correspondingly located in the first guide rail 134a, and the elastic element 160 abuts the slide rail 150. The sliding rail 150 abuts the support post 140 so that the support post 140 and the limit seat 120 tightly clamp the ball shaft 170 together, and the ball shaft 170 is fixed, and therefore cannot swing relative to the limit seat 120.

It is worth noting that the structure of the inner sliding rail 134 of the fixing seat 130, the rib 154 of the sliding rail 150, the upper sliding rail portion 152 of the sliding rail 150 and the lower rail portion 144 of the supporting column 140 cooperate with each other. As a result, the user can apply force to the ball shaft 170, and by a simple pressing action, the elastic element 160 is compressed, and the support column 140 moves toward the base 110, so that the distance between the support column 140 and the limit seat 120 It is larger than the diameter of the ball portion 172 of the ball shaft 170, so the ball portion 172 has a degree of freedom of rotation and can rotate relative to the limit seat 120.

FIG. 4 is a schematic diagram of the ball shaft 170 pressing the support frame. When the angle of the ball shaft 170 relative to the limit seat 120 is to be adjusted, the ball shaft 170 can be pressed to move the ball shaft 170 toward the base 110.

4A is a schematic diagram of the sliding rail member 150 rotating along the inner sliding rail 134 of the fixing seat 130, FIG. 4B is a schematic diagram of the support column 140 descending relative to the limit seat 120, and FIG. 4C is a schematic diagram along the AA section line of FIG. . Please refer to FIGS. 4A, 4B and 4C at the same time. After the user presses the ball shaft 170 to move the ball shaft 170 toward the base 110, as the ball shaft 170 moves toward the base 110 under force, the ball portion of the ball shaft 170 172 pushes the support column 140, and the lower rail portion 144 of the support column 140 pushes the upper rail portion 152 of the slide rail member 150, and the slide rail member 150 opposes by the interference of the rib 154 and the inner slide rail 134 of the fixing base 130 After the fixing base 130 rotates, the user no longer applies force. Therefore, the sliding rail 150 has both movement and rotation relative to the support column 140 at the same time. As the sliding rail 150 also moves toward the base 110, the sliding rail 150 presses the elastic element 160, and the elastic element 160 is deformed by force to store the elastic restoring force.

Furthermore, the ribs 154 of the slide rail 150 are initially pressed against the third guide rail 134c by the elastic restoring force of the elastic element 160. When the user applies force, the slide rail 150 is simultaneously opposed to the support column 140. When moving and rotating, the ribs 154 of the slide rail 150 are detached from the third guide rail 134c of the inner slide rail 134 of the fixed seat 130 and then slide along the bottom end of the second guide rail 134b. It should be noted that the second guide rail The bottom ends of 134b and the third guide rail 134c are inclined surfaces, that is, the viewing angle in FIG. 4C is a low left and right high slope. Therefore, when the rib 154 slides along the bottom end of the second guide rail 134b or the third guide rail 134c, it will drive sliding The rail 150 rotates counterclockwise. Since the bottom ends of the first rail 134a, the second rail 134b, and the third rail 134c have different lengths (or heights) in the height direction, the rib 154 is limited by the second rail 134b and stops on the first rail At the bottom end of 134a, the slide rail 150 can no longer rotate at this time. At the same time, the top end of the upper slide rail portion 152 stays on the bottom slope of the corresponding first guide rail 134a, and the slide rail 150 is restricted and fixed at a certain height.

Then, the ball shaft 170 is pressed again, and the top end of the upper sliding rail portion 152 follows the contour of the second rail 134b and then enters the third rail 134c. As the rib 154 passes from the first guide rail 134a through the second guide rail 134b and is locked into the third guide rail 134c, the slide rail 150 can rotate and move in height relative to the fixed base 130 at the same time.

FIG. 5 is a schematic diagram of the ball shaft 170 swinging relative to the limit seat 120. Please refer to FIG. 5, in particular, when the rib 154 is guided by the second guide rail 134b or locked into the third guide rail 134c, the slide rail 150 will continue to apply pressure to the elastic element 160, and at this time the support column 140 The distance from the limit seat 120 is greater than the diameter of the ball portion 172, so the ball portion 172 of the ball shaft 170 has a degree of freedom of rotation and can swing relative to the limit seat 120.

Incidentally, since the fixing base 130 and the limiting base 120 are connected together by the hook 132 provided on the fixing base 130 being hooked to the inner ring 122 of the limiting base 120, when the rib 154 of the sliding rail 150 It snaps into the third guide rail 134c of the inner slide rail 134 of the fixed seat 130, so that the support column 140 is not supported by the slide rail 150, causing the ball shaft 170, the limit seat 120 and the support column 140 to move toward the base 110 only by gravity. Therefore, the inner ring 122 of the limiting seat 120 is not restricted by the hook 132 of the fixing seat 130, so the limiting seat 120 can also rotate relative to the fixing seat 130 at this time. In this way, the support base 100 can provide a large adjustment angle of the lens provided at the end of the shaft portion 174 of the ball shaft 170.

When the ball shaft 170 needs to be fixed, it is only necessary to press the ball shaft 170 again to make the slide rail 150 rotate relative to the fixing base 130 again, so that the ribs 154 of the slide rail 150 are locked into the inner sliding of the fixing base 130 again In the first guide rail 134a of the rail 134, and the slide rail 150 stops pressing the elastic element 160 at this time, the compressed elastic element 160 is released and provides elastic restoring force, and the support column 140 is pushed to move the ball shaft 170 to the limit seat When 120 is pressed against, the support column 140 and the limit seat 120 tightly clamp the ball portion 172 of the ball shaft 170, so the ball shaft 170 is also difficult to rotate relative to the limit seat 120.

At the same time, the support column 140 is pushed against the ball shaft 170 by the elastic element 160, which will prompt the limit seat 120 to move relatively away from the base 110, so the inner ring 122 of the limit seat 120 and the hook 132 of the fixed seat 130 form The tight engagement makes the limit seat 120 also be fixed relative to the fixed seat 130, and it is difficult to rotate relative to the fixed seat 130.

Incidentally, the groove 120a of the ball portion 172 of the limit seat 120 for receiving the ball shaft 170 conforms to the ball portion 172, and the diameter of the groove 120a can be equal to or larger than the diameter of the ball portion 172, so that the ball shaft 170 can It is easy to rotate relative to the fixed base 130. When the rib 154 of the slide rail 150 is correspondingly positioned in the first guide rail 134a, the elastic force exerted by the elastic element 160 makes the top end of the columnar portion 142 of the support column 140 and the limit seat 120 firmly clamp the auxiliary ball shaft 170 Therefore, the ball shaft 170 cannot rotate freely relative to the fixed seat 130.

In summary, the support base of the present invention has at least the following advantages:

1. The structure is novel, the fixing between the ball shaft and the limit seat does not require the use of screws and nuts, which can reduce the use of parts and avoid the loss of disassembled screws and nuts.

2. Because the fixing of the ball shaft with respect to the limit seat does not use screws and nuts, the user can change the ball shaft from a tightly clamped state to having freedom of rotation by pressing without using hand tools. The angle of the ball shaft relative to the limit seat can be easily adjusted.

3. The state of the ball shaft and the limit seat can be changed through the pressing action, which has the advantages of simple and convenient operation for the user.
