Description

Technical Field

[0001] The present invention relates to the field of shooting auxiliary devices, and particularly to a clamping device and a selfie stick. Background Art

[0002] In a selfie stick or a handheld stabilizer, a mobile phone clamping device is often used. The existing mobile phone clamping device includes a support member, and a first clamping member and a second clamping member arranged at both ends of the support member. A clamping space for clamping a mobile phone or other electronic devices is formed between the first clamping member and the second clamping member. Wherein, at least one clamping member can be connected with the support member through a pull rod to form a stretchable structure. At the same time, one or more accommodating holes for accommodating the pull rod are arranged on the support member. In order to facilitate the installation of the pull rod, the accommodating holes are usually arranged as through holes to penetrate the support member longitudinally.

[0003] During the injection molding process of the support member, two strands of material flow will be formed when filling the periphery of the accommodating hole. When the two strands of material flow meet and weld, a weld mark will be generated. Due to the relatively deep depth of the accommodating hole, a long and obvious weld mark will be formed on the outer surface of the support member. The exposed weld mark will not only affect the appearance of the support member, but also easily deteriorate the mechanical properties of the support member itself, and there is a risk of fracture during the use of the clamping device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a clamping device aiming at the above defects of the prior art, so that the overall appearance of the clamping device is beautiful, and at the same time, the mechanical properties of the whole device can be improved as a whole.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a clamping device, including a support member provided with an accommodating hole along the clamping direction; a housing provided with an accommodating space for accommodating the support member, the support member is installed in the accommodating space, and the housing is provided with a through hole along the clamping direction; a clamping member, one end of which is connected with a pull rod, and the other end of the pull rod passes through the through hole and can slide in the accommodating hole.

[0006] A further preferred solution of the present invention is: an opening for loading the support member is provided on the housing, the opening is communicated with the accommodating space, and after the support member is loaded into the accommodating space, all or part of the opening is blocked.

[0007] A further preferred solution of the present invention is: one of the support member and the housing is provided with a clamping groove, and the other is provided with a clamping buckle, and the clamping buckle and the clamping groove are engaged in a matching manner.

[0008] A further preferred solution of the present invention is: the opening direction of the opening is perpendicular to the clamping direction.

[0009] A further preferred solution of the present invention is that a rubber pad is provided on the side of the support member at the opening.

[0010] A further preferred solution of the present invention is that the support member includes a clamping portion and a connecting portion. The connecting portion is connected to both sides of the clamping portion. The clamping portion is formed with a support portion extending in a direction perpendicular to the clamping direction. The rubber pad is provided on the surfaces of the clamping portion and the support portion, and the rubber pad located on the support portion is higher than the height of the connecting portion.

[0011] A further preferred solution of the present invention is that the accommodating hole is provided as a through hole.

[0012] A further preferred solution of the present invention is that the caliber of the through port is adapted to the pull rod, and corresponds to the position and number of the accommodating holes.

[0013] A further preferred solution of the present invention is that two clamping members are provided and are arranged oppositely. At least one pull rod is provided on each clamping member. The number of the accommodating holes corresponds to the number of the pull rods. The two clamping members respectively slide in the accommodating holes through the pull rods to approach or move away from the support member, and a clamping space is formed between the two clamping members.

[0014] A further preferred solution of the present invention is that two pull rods are provided on each clamping member.

[0015] A further preferred solution of the present invention is that one clamping member is provided, and a convex block is formed by extending the other side of the support member or the housing away from the clamping member. A clamping space is formed between the convex block and the clamping member.

[0016] A further preferred solution of the present invention is that a reset member is further included. The reset member is arranged in the accommodating hole and is used for driving the pull rod to slide into the accommodating hole.

[0017] A further preferred solution of the present invention is that the reset member is a spring. A resisting block is provided at the end of the pull rod located in the accommodating hole. The spring is sleeved on the pull rod and is clamped between the resisting block and the hole wall of the accommodating hole.

[0018] The second solution provided by the present invention: A selfie stick further includes a selfie stick main body and the clamping device in the above solution. The selfie stick main body is connected to the clamping device.

[0019] The beneficial effects of the present invention are as follows: By providing a housing which is provided with a receiving space and a through hole, compared with the receiving hole of the support member, the housing does not have a too deep hole. During the injection molding process of the housing, by reasonably setting the position of the gate, the position where the weld mark of the housing appears can be controlled inside the housing without being exposed, ensuring that the exposed surface of the housing is more beautiful. At the same time, since the support member can be received in the housing, the housing can cover the weld mark on the support member. Additionally, in terms of mechanical properties, since the support member is received in the housing, external forces will not directly act on the support member, enabling the mechanical properties of the entire device to be greatly improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] It should be understood that the terms, the specific structures and functional details disclosed herein are only for the purpose of describing specific embodiments, which are representative, but the present invention can be specifically implemented in many alternative forms and should not be construed as being limited only to the embodiments set forth herein.

[0027] The following Figure 1 refers to the attached Figure 4 drawings and optional embodiments to further illustrate the present invention.

[0028] Please refer toFigures 1 to 4 , the present invention provides a clamping device, which includes a support member 100 provided with a receiving hole 110 along the clamping direction; a housing 200 provided with a receiving space 210 for receiving the support member 100, the support member 100 is installed in the receiving space 210, and the housing 200 is provided with a through hole 220 along the clamping direction; a clamping member 300, one end of which is connected with a pull rod 400, and the pull rod 400 can slide in the receiving hole 110 after passing through the through hole 220.

[0029] By providing the housing 200, the housing 200 is provided with a receiving space 210 and a through hole 220. Compared with the receiving hole 110 of the support member 100, the through hole 220 is not deep or the through hole 220 can be directly set as a notch for the receiving space 210 to communicate with the outside (that is, the entire or part of the side of the support member 100 where the receiving hole 110 is opened can be directly exposed through the through hole 220). During the injection molding process of the housing 200, by reasonably setting the position of the gate, the position where the weld mark of the housing 200 appears can be controlled inside the housing 200 without being exposed, ensuring that the exposed surface of the housing 200 is more beautiful. At the same time, since the support member 100 can be received in the housing 200, the housing 200 can cover the weld mark on the support member 100. In addition, in terms of mechanical properties, since the support member 100 is received in the housing 200, the external force will not directly act on the support member 100, so that the mechanical properties of the entire device can be greatly improved, and the clamping device is not easily broken. See Figure 2 , the clamping device in the prior art is equivalent to the state of the present device when the housing 200 is not installed. Since the support member 100 needs to be provided with a relatively deep receiving hole 110 to receive the pull rod 400, it is easy to form a weld mark on the outer side surface of the support member 100, and the weld mark affects the appearance and mechanical properties of the entire device.

[0030] Specifically, see Figure 1 and Figure 3 , an opening for the support member 100 to be inserted is provided on the housing 200, and the opening is communicated with the receiving space 210. After the support member 100 is inserted into the receiving space 210, the opening is completely or partially blocked. The housing 200 is a hollow housing 200 with an opening on one side. The support member 100 is received in the receiving space 210 of the housing 200 through the opening. In this embodiment, the outer shape of the housing 200 matches the outer shape of the support member 100, ensuring that the housing 200 can fit well on the support member 100; at the same time, after the support member 100 is inserted into the receiving space 210, the opening is directly completely or partially blocked, thus facilitating the installation and disassembly of the device without additionally adding an end cover to block the opening.

[0031] Continue to see Figure 1, a support member 100 and a housing 200, one of which is provided with a clamping groove 160 and the other is provided with a clamping buckle 240, and the clamping buckle 240 and the clamping groove 160 are aligned and engaged with each other. Thus, through the clamping structure of the support member 100 and the housing 200, the positioning and fixing of the support member 100 in the accommodation space 210 can be facilitated. Of course, in other embodiments, the support member 100 can also be stably mounted on the housing 200 through other clamping structures, such as a structure with a plug rod and a jack. The opening direction of the housing 200 is perpendicular to the clamping direction, so as to ensure that the opening is large enough to facilitate the installation of the support member 100. In addition, a rubber pad 600 is provided on the side surface of the support member 100 at the opening. The rubber pad 600 can prevent the photographing / shooting device in the clamping space from directly contacting the support member 100, thereby preventing the photographing / shooting device from being scratched, and can also block a part of the area of the support member 100 exposed within a certain range, so as to avoid the exposed welding marks on the support member 100 to a certain extent.

[0032] Furthermore, the support member 100 includes a clamping portion 120 and a connecting portion 130. The connecting portion 130 is connected to both sides of the clamping portion 120. The clamping portion 120 is formed with a support portion 150 extending in a direction perpendicular to the clamping direction. The rubber pad 600 is provided on the surfaces of the clamping portion 120 and the support portion 150, and the rubber pad 600 located on the support portion 150 is higher than the height of the connecting portion 130. Thus, the setting of the support portion 150 can increase the range of the support member 100 for laterally abutting and supporting the photographing / shooting device, making it more convenient to support the photographing / shooting device. In addition, the rubber pad 600 located on the support portion 150 can prevent the photographing / shooting device from directly contacting the connecting portion 130, thereby preventing the photographing / shooting device from being scratched. In this embodiment, the edge shape of the support portion 150 is arc-shaped. Of course, it can also be other shapes, such as rectangular or wavy. However, in this embodiment, by setting the edge of the support portion 150 as arc-shaped, it is not easy to scratch the hand.

[0033] Furthermore, the clamping surface 140 of the support member 100 is an arc surface, and the shape of the rubber pad 600 matches the shape of the clamping surface 140 of the support member 100. Generally, a selfie stick includes a selfie stick main body and a clamping device. The selfie stick is connected to the clamping device. Since the handle of the selfie stick main body is often cylindrical, when the clamping surface 140 of the support member 100 is an arc surface, when the clamping device is folded on the handle, it can fit well on the handle. Of course, it can be understood that the clamping surface 140 of the support member 100 can also be a square surface, and the clamping surface 140 of the support member 100 is not limited to an arc surface.

[0034] Further, a cover 230 is provided on the outer surface of the housing 200, and the cover 230 is snap-fitted with the edge of the support portion 150. Since the support portion 150 is relatively thin, it is very easy to touch the support portion 150 during use. If the force is a little greater, the support portion 150 is very easy to be broken. On the other hand, since the support portion 150 protrudes from the support member 100, it is very easy to scratch the hand. In this embodiment, by providing the cover 230 and snap-fitting the cover 230 with the edge of the support portion 150, it is not easy to touch the support portion 150, the support portion 150 is not easy to be broken, and it is not easy to scratch the hand. Also, since the volume of the cover 230 is relatively large, it is not easy to break when touched. In this embodiment, the edge of the support portion 150 is arc-shaped, so the shell wall of the cover 230 snap-fitted with the edge of the support portion 150 is an arc surface, and the shell wall is not easy to scratch the hand.

[0035] See Figure 1 and Figure 2 , the accommodating hole 110 is provided as a through hole. The through hole facilitates the loading of the pull rod 400 and can accommodate the longest pull rod 400 under the condition that the volume of the support member 100 is fixed; the caliber of the through port 220 is adapted to the pull rod 400 and corresponds to the position and quantity of the accommodating hole 110. That is to say, the through port 220 only needs to be opened to a size for the pull rod 400 to pass through, so as to ensure that the housing 200 can maximally block the side surface of the support member 100, prevent the side surface of the support member 100 from being exposed, and maximally prevent the support member 100 from being directly affected by external forces.

[0036] See Figures 1 - 3 , two clamping members 300 are provided and are arranged oppositely. At least one pull rod 400 is provided on each clamping member 300. The quantity of the accommodating holes 110 corresponds to the quantity of the pull rods 400. The two clamping members 300 slide in the accommodating holes 110 through the pull rods 400 to approach or move away from the support member 100, and a clamping space is formed between the two clamping members 300. Thus, the two clamping members 300 form a variable clamping space through the sliding of the pull rods 400 in the accommodating holes 110 to facilitate clamping of photographing / shooting devices of different sizes. In order to ensure the stability of the clamping member 300 during the formation of the variable clamping space, two pull rods 400 are provided on each clamping member 300, so that the clamping member 300 is more evenly stressed during the pulling process.

[0037] Of course, in other embodiments, the clamping member 300 may also be provided as one, and a convex block (not shown in the figure) extends from the other side of the support member 100 or the housing 200 away from the clamping member 300, and a clamping space is formed between the convex block and the clamping member 300.

[0038] In this embodiment, the clamping device further includes a reset member 500 disposed in the receiving hole 110 for driving the pull rod 400 to slide into the receiving hole 110. In this way, when the clamping member 300 is pulled open, the reset member can provide a clamping force for the clamping member 300 to clamp the electronic device.

[0039] In this embodiment, the reset member 500 is a spring. A resisting block 410 is provided at the end of the pull rod 400 located in the receiving hole 110. The spring is sleeved on the pull rod 400 and clamped between the resisting block 410 and the hole wall of the receiving hole 110. When the pull rod 400 slides outward in the receiving hole 110, the resisting block 410 will also move outward along with the movement of the pull rod 400, thereby compressing the spring between the resisting block 410 and the hole wall of the receiving hole 110. After the spring is compressed, a force is correspondingly provided to drive the pull rod 400 to slide into the receiving hole 110, so that the pull rod 400 has a restoring force to retract into the receiving hole 110. This restoring force can make the clamping member 300 connected to the pull rod 400 clamp the electronic device. To ensure the stability of the pull rod 400 of the device in the receiving hole 110, the spring clamped between the resisting block 410 and the hole wall of the receiving hole 110 is always in a compressed state, so that the pull rod 400 always has an elastic force to drive it to slide into the receiving hole 110 during use.

[0040] Certainly, in other embodiments, there are other ways to install the spring. For example, one end of the spring is connected to the pull rod 400, and the other end is connected to the shell wall of the support member 100 in the opposite direction of the outward movement direction of the pull rod 400. When the pull rod 400 moves outward, the spring is stretched, generating a pulling force on the pull rod 400, and this pulling force can make the pull rod 400 clamp the electronic device. Certainly, the reset member 500 is not limited to the structure of a spring, and can also be two magnets. One magnet is installed at the suspended end of the pull rod 400, and the other magnet that attracts each other is installed on the shell wall of the support member 100 in the opposite direction of the outward movement direction of the pull rod 400.

[0041] In the second aspect of this embodiment, a selfie stick is provided, which further includes a selfie stick main body and the clamping device in the above solution, and the selfie stick main body is connected to the clamping device.

[0042] By providing the housing 200, the housing 200 is provided with a receiving space 210 and a through-hole 220. Compared with the receiving hole 110 of the support member 100, the through-hole 220 is not deep. During the injection molding process of the housing 200, by reasonably setting the position of the gate, the position where the weld mark of the housing 200 appears can be controlled inside the housing 200 without being exposed, ensuring that the exposed surface of the housing 200 is more beautiful. At the same time, since the support member 100 can be received in the housing 200, the housing 200 can cover the weld mark on the support member 100. In addition, in terms of mechanical properties, since the support member 100 is received in the housing 200, external forces will not directly act on the support member 100, which can greatly improve the mechanical properties of the entire device and make the clamping device not easily break.

[0043] The above content is a further detailed description of the present invention in combination with specific optional embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the present invention.
