Description

Technical Field

[0001] The utility model relates to the technical field of chucks, in particular to a chuck head claw distance adjustment mechanism. Background Art

[0002] As cars are gradually becoming commonplace for ordinary consumers, their requirements for car functionality are also increasing. For drinking convenience, cars generally have cup holders specifically designed for placing water cups, which are typically secured with a clip in the cup holder.

[0003] A Chinese patent (patent number CN112026614B) discloses a vehicle cup holder with upper and lower clamping claws, comprising a cup holder provided with a mounting portion and a receiving cavity, wherein the mounting portion includes an upper mounting opening and a lower mounting opening, both of which are connected to the receiving cavity; a clamping claw assembly, wherein the upper clamping claw is disposed within the upper mounting opening and adopts an upper and lower clamping claw structure, which can firmly fix the upper and lower parts of the cup to prevent the cup from shaking when the car is driving.

[0004] However, water cups come in different sizes. Some are slender, while others are short but have a larger outer diameter. If you use the same type of cup holder, the cup with a larger outer diameter may have too much clamping force from the cup holder, making it inconvenient to take out. The cup with a smaller outer diameter may have less clamping force from the cup holder, making it easy for the cup to pop out when the vehicle is bumpy. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present invention is to provide a clamping head claw distance adjustment mechanism that can adapt to cups of different diameters.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a clamping head claw distance adjustment mechanism, comprising a cup holder, wherein the cup holder has a receiving cavity, the cup holder has a socket, a clamping claw assembly is slidably provided on the cup holder and located at the socket, and a driving member is installed on the cup holder for driving the clamping claw assembly to move radially along the cup holder;

[0007] The driving member includes a rotating circle rotatably arranged on the outside of the cup holder, and a ramp block adapted to the claw assembly is fixedly installed on the inner wall of the rotating circle. The ramp block gradually approaches the axis of the rotating circle along the circumference of the rotating circle. A first magnetic block is fixedly installed on the ramp block, and a second magnetic block is installed on the claw assembly. The first magnetic block is always in contact with the second magnetic block.

[0008] Furthermore, the claw assembly includes a claw, a cover is provided on the outside of the claw, the cover is located in the socket, a spring is fixedly installed between the claw and the inner wall of the cover, and the second magnetic block is installed on the cover.

[0009] Furthermore, a guide block is fixedly mounted on the inner wall of the socket, and a sliding groove for the guide block to slide is provided on the outer wall of the cover shell.

[0010] Furthermore, a side of the clamping claw away from the housing is provided with an inclined surface for inserting and disengaging the cup body.

[0011] Furthermore, a roller is rotatably mounted on the side of the claw away from the cover.

[0012] Furthermore, the two groups of claw assemblies are distributed in sequence along the vertical direction of the cup holder.

[0013] Furthermore, each group of the claw assemblies includes at least two claw assemblies, which are distributed along the circumference of the cup holder.

[0014] Furthermore, the cup holder is fixedly mounted on the vehicle frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: when the position of the claw assembly needs to be adjusted, if the outer diameter of the cup is small, the rotating circle is manually rotated to drive the ramp block to move, and the inclined surface of the ramp block pushes the second magnetic block to move away from the ramp block, thereby pushing the claw assembly; if the outer diameter of the cup is too large, the rotating circle is reversed to drive the ramp block to move in the opposite direction. Since the first magnetic block and the second magnetic block are magnetically attracted to each other and are always in contact, the claw assembly is driven to move away from the middle of the cup holder, thereby achieving the effect of adapting to cups of different diameters.

DETAILED DESCRIPTION

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 and Figure 2 The present embodiment provides a mechanism for adjusting the claw distance of a clamping head, including a cup holder 1, which is fixedly mounted on a vehicle frame 9. A receiving cavity 2 is provided in the cup holder 1, a socket 3 is provided on the cup holder 1, a clamping claw assembly 4 is slidably provided on the cup holder 1 and located at the socket 3, and a driving member 5 is installed on the cup holder 1 for driving the clamping claw assembly 4 to move radially along the cup holder 1.

[0023] First, according to the outer diameter of the water cup, the driving member 5 drives the claw assembly 4 to move radially along the cup holder 1 to a suitable position, and then the cup is inserted into the accommodating cavity 2 from the upper opening of the cup holder 1, so that the outer wall of the water cup abuts against the claw assembly 4. The friction between the claw assembly 4 and the cup wall prevents the cup from easily falling out of the cup holder 1, thereby restraining the cup.

[0024] See also Figure 2 and Figure 4 The driving member 5 includes a rotating circle 51 rotatably arranged on the outside of the cup holder 1. A ramp block 52 adapted to the claw assembly 4 is fixedly installed on the inner wall of the rotating circle 51. The ramp block 52 gradually approaches the axis of the rotating circle 51 along the circumference of the rotating circle 51. A first magnetic block 53 is fixedly installed on the ramp block 52, and a second magnetic block 54 is installed on the claw assembly 4. The first magnetic block 53 is always in contact with the second magnetic block 54.

[0025] When the position of the claw assembly 4 needs to be adjusted, the rotating ring 51 is manually rotated to drive the ramp block 52 to move. When the claw assembly 4 needs to be pushed toward the middle of the cup holder 1, that is, when the outer diameter of the inserted cup is small, the inclined surface of the ramp block 52 pushes the second magnetic block 54 away from the ramp block 52, thereby pushing the claw assembly 4.

[0026] If the outer diameter of the cup is too large, the claw assembly 4 needs to be moved away from the rotating circle 51. By reversing the rotating circle 51, the rotating circle 51 drives the ramp block 52 to move in the opposite direction. Because the first magnetic block 5353 and the second magnetic block 54 are magnetically attracted to each other and are always in contact, when the ramp block 52 is reversed, the magnetic attraction between the first magnetic block 53 and the second magnetic block 54 drives the claw assembly 4 to move away from the middle of the cup holder 1.

[0027] In order to facilitate the rotation of the rotating circle 51, a plurality of convex circles are fixedly installed on the circumference of the upper side of the rotating circle 51, so as to facilitate the rotation of the rotating circle 51 by friction of the hand.

[0028] See also Figure 2 and Figure 4 The claw assembly 4 includes a claw 41, a cover 42 is provided on the outside of the claw 41, the cover 42 is located in the socket 3, a spring 43 is fixedly installed on the claw 41 and the inner wall of the cover 42, and the second magnetic block 54 is installed on the cover 42.

[0029] When the claw 41 contacts the cup wall, the cup wall presses the claw 41 , causing the claw 41 to press the spring 43 . The spring 43 provides pressure between the claw 41 and the cup wall, thereby providing friction to prevent the cup from easily leaving the cup holder 1 .

[0030] See also Figure 4 In order to keep the cover 42 moving stably under the drive of the driving member 5, a guide block 6 is fixedly installed on the inner wall of the socket 3, and a sliding groove 7 for the guide block 6 to slide is opened on the outer wall of the cover 42.

[0031] When the cover shell 42 slides in the socket 3 , the guide block 6 cooperates with the slide groove 7 , thereby improving the stability of the movement of the cover shell 42 .

[0032] During the process of inserting the cup into the accommodating cavity 2 , if the upper side of the clamping claw 41 is horizontal, it is necessary to manually move the clamping claw 41 to retract it before the cup can be inserted into the accommodating cavity 2 , which is rather cumbersome.

[0033] See also Figure 2 In order to solve the above technical problems, the side of the claw 41 away from the cover 42 is provided with an inclined surface for the cup body to be inserted into and out of.

[0034] When the cup is inserted into the accommodating cavity 2, the bottom of the cup contacts the inclined surface of the claw 41, thereby pushing the claw 41 to retract into the cover 42, making it easier for the claw 41 to contact the side wall of the cup. If there is a protrusion on the side wall of the cup, after the protrusion passes over the claw 41, when you want to take the cup out, the protrusion will also contact the inclined surface on the lower side of the claw 41, causing the claw 41 to retract into the cover 42, making it easier for the cup to be inserted and removed.

[0035] If the claw 41 and the cup are in sliding friction, it is easy to cause scratches on the side of the cup. To solve the above technical problem, a roller 8 is rotatably mounted on the side of the claw 41 away from the cover 42. This allows the roller 8 to contact the cup, reducing the scratches on the cup side.

[0036] The two groups of claw assemblies 4 are distributed in sequence along the vertical direction of the cup holder 1, thereby limiting the upper and lower side walls of the cup and improving the stability of the cup.

[0037] See also Figure 3Each group of claw assemblies 4 has at least two claw assemblies distributed along the circumference of the cup holder 1, thereby clamping the side wall of the cup.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
