Abstract
Description
Technical Field
[0001] This utility model relates to the field of drawer guide rail technology, and in particular to a three-dimensional adjustable handle for a two-section guide rail. Background Technology
[0002] A three-dimensional adjustable handle is an adjustment mechanism used on drawer slides. It generally has the functions of front-to-back, up-down, and left-to-right adjustment. By adjusting its position relative to the slide, the installation height of the drawer can be changed. During installation, the slide is installed on the cabinet body, and the adjustable handle is installed at the bottom of the drawer. The drawer is supported on the slide while the slide and the adjustable handle are connected, thereby fixing the drawer on the slide. This corrects installation deviations and ensures that the drawer is aligned and stable. It is widely used in furniture such as cabinets and wardrobes.
[0003] Existing three-dimensional adjustable handles include a mounting base and vertical adjustment components, horizontal adjustment components, and front-back adjustment components that are respectively assembled with the mounting base. Each adjustment component generally consists of an adjustment wheel and an adjustment element, which are connected by threads. The outer end of the adjustment element is an adjustment wedge. When the adjustment wheel is rotated, the adjustment wedge will extend or retract relative to the mounting base, thereby realizing the adjustment of the drawer and guide rail in various dimensions. The vertical and horizontal adjustment components are usually assembled inside the mounting base, while the front-back adjustment components are assembled outside the mounting base. For a more aesthetically pleasing product, the front projection surface of the front-back adjustment component is usually designed to be completely located on the mounting base.
[0004] However, since the overall structure of the three-dimensional adjustment handle is usually located at the bottom of the drawer, the user's line of sight is blocked by the drawer body when making adjustments, and it is often impossible to directly observe the specific position of the adjustment wheel. Therefore, the adjustment wheel must be adjusted blindly by hand. In the structure of the above-mentioned prior art, the front and rear adjustment components are completely located on the mounting base. Therefore, the user can only adjust by relying solely on the setting direction of the adjustment wheel. The setting direction of the front and rear adjustment wheel is the same as that of the up and down adjustment wheel and the left and right adjustment wheel. This makes it easy for the user to make mistakes when adjusting blindly, which affects the use effect. Utility Model Content

It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof.
[0040] Example: Figure 1-5 As shown, a two-section guide rail three-dimensional adjustable handle includes a base 1, a front-to-back adjustment mechanism 2, an up-down adjustment mechanism 3 and a left-to-right adjustment mechanism 4 assembled in the base 1. The front-to-back adjustment mechanism 2 is mounted on the top of the base 1 and includes front-to-back adjustment wheels 23, which are exposed on the base 1. The up-down adjustment mechanism 3 is used to adjust the up-down position of the drawer and the guide rail, the front-to-back adjustment mechanism 2 is used to adjust the front-to-back position of the drawer and the guide rail, and the left-to-right adjustment mechanism 4 is used to adjust the left-to-right position of the drawer and the guide rail. By setting the front-to-back adjustment wheels 23 of the front-to-back adjustment mechanism 2 to be exposed on the base 1, the setting position is significantly different from that of the adjustment mechanisms in other directions, making it easier for users to blindly adjust the front-to-back direction of the guide rail and the drawer, and reducing the likelihood of adjusting the wrong direction.
[0041] The front-to-back adjustment mechanism 2 further includes a front-to-back adjustment seat 21 and a front-to-back adjustment member 22. The side wall of the front-to-back adjustment seat 21 has a through hole 211 and a third through groove 212 for restricting the front-to-back movement of the front-to-back adjustment wheel 23. The through hole 211 communicates with the third through groove 212. The front-to-back adjustment wheel 23 is assembled in the third through groove 212. The front-to-back adjustment member 22 passes through the through hole 211 and is rotatably assembled in the front-to-back adjustment wheel 23. When the front-to-back adjustment wheel 23 rotates, the front-to-back adjustment member 22 moves back and forth relative to the base 1. By setting the front-to-back adjustment wheel 23 to be assembled in the third through groove 212 in the front-to-back adjustment seat 21, the front-to-back movement of the front-to-back adjustment wheel 23 is restricted. When the front-to-back adjustment wheel 23 rotates, the front-to-back adjustment wheel 23 drives the front-to-back adjustment member 22 to move in the front-to-back direction, thereby adjusting the front-to-back position of the drawer and the guide rail.
[0042] The front and rear adjusting wheel 23 has a third threaded hole in its middle. The front and rear adjusting member 22 includes a third screw 221 threadedly connected to the third threaded hole and a front and rear adjusting block 222 connected to the rear end of the third screw 221. The side wall of the front and rear adjusting block 222 has a top block 2221 protruding to the right. The third screw 221 is threadedly rotatably assembled with the front and rear adjusting wheel 23. When the front and rear adjusting mechanism 2 is adjusted, the front and rear adjusting wheel 23 is rotated, and the front and rear adjusting wheel 23 drives the third screw 221 to move back and forth, so that the top block 2221 pushes the guide rail forward when it extends, or the guide rail retracts backward when it retracts.
[0043] The base 1 has mounting holes 7 on its bottom wall, which allows the three-dimensional adjustment handle to be mounted on the drawer with screws.
[0044] The outer wall of the top block 2221 is provided with an arc-shaped surface 2222. The arc-shaped surface 2222 is gradually inclined from the rear of the top block 2221 toward the front of the top block 2221. By providing the arc-shaped surface 2222, its shape is designed so that the projection surface of the top block 2221 does not block the mounting hole 7, thereby facilitating the installation of the three-dimensional adjustment handle on the guide rail.
[0045] The front and rear adjustment block 222 has a forward-protruding rib 2223 on its side wall, and the front and rear adjustment seat 21 has a recessed hole 213 on its inner wall. The rib 2223 is slidably fitted in the recessed hole 213. By setting the rib 2223 to be slidably fitted in the recessed hole 213 of the front and rear adjustment seat 21, the adjustment process of the front and rear adjustment block 222 in the front and rear direction is more stable and will not deviate in the left and right direction, thus affecting the support effect on the guide rail.
[0046] The base 1 has a snap-fit groove 11 on its top wall facing downwards. The bottom wall of the front and rear adjustment seat 21 is snapped into the inner wall of the snap-fit groove 11. By setting the snap-fit groove 11, the assembly effect between the front and rear adjustment seat 21 and the base 1 is improved, and the adjustment process of the front and rear adjustment block 222 is more stable.
[0047] The bottom wall of the front-rear adjustment member 22 is provided with a sliding groove 214, and the top wall of the base 1 is provided with a sliding strip 12 protruding upward. The sliding strip 12 is slidably assembled on the inner wall of the sliding groove 214. By setting the sliding strip 12 and the sliding groove 214, the front-rear adjustment member 22 is more stable in the front-rear direction adjustment process relative to the base 1.
[0048] The front and rear adjustment seat 21 is detachably mounted on the top of the base 1, which facilitates repair and replacement in case of damage.
[0049] The base 1 has a first receiving cavity 101 and a fourth receiving cavity 104 that are interconnected. The up-down adjustment mechanism 3 includes an up-down adjustment wheel 31 disposed in the first receiving cavity 101 and an up-down adjustment member 32 that moves back and forth in the fourth receiving cavity 104. The side wall of the first receiving cavity 101 is provided with a first through groove 1011 for restricting the back-and-forth movement of the up-down adjustment wheel 31. The up-down adjustment wheel 31 is assembled in the first through groove 1011. The up-down adjustment member 32 is rotatably assembled with the up-down adjustment wheel 31. When the up-down adjustment wheel 31 rotates, the up-down adjustment member 32 moves back and forth relative to the base 1. By setting the up-down adjustment wheel 31 to be assembled in the first through groove 1011 in the base 1, the back-and-forth movement of the up-down adjustment wheel 31 is restricted. When the up-down adjustment wheel 31 rotates, the up-down adjustment wheel 31 drives the up-down adjustment member 32 to move in the back-and-forth direction, thereby adjusting the up-and-down position of the drawer and the guide rail.
[0050] The upper and lower adjusting wheel 31 has a first screw hole through its middle. The upper and lower adjusting component 32 includes a first screw 321 threadedly connected to the first screw hole and a P-shaped block 322 connected to the front end of the first screw 321. The first screw 321 is threadedly rotatably assembled with the upper and lower adjusting wheel 31. When the upper and lower adjusting mechanism 3 is adjusted, the upper and lower adjusting wheel 31 is rotated, and the upper and lower adjusting wheel 31 drives the first screw 321 to move back and forth, so that the P-shaped block 322 adjusts the upper and lower positions of the drawer and the guide rail.
[0051] The P-shaped block 322 has a beveled surface 3221 at its front end. The beveled surface 3221 is gradually inclined from the top of the P-shaped block 322 toward the bottom of the P-shaped block 322. By rotating the up and down adjustment wheel 31, the P-shaped block 322 is moved back and forth, and the beveled surface 3221 extends forward into the guide rail, raising the drawer and achieving the purpose of adjusting the gap between the drawer and the guide rail.
[0052] The base 1 has a third receiving cavity 103 communicating with the fourth receiving cavity 104. The left and right adjustment mechanism 4 includes a left and right adjustment wheel 41 disposed in the third receiving cavity 103 and a left and right adjustment member 42 that moves left and right within the fourth receiving cavity 104. The side wall of the third receiving cavity 103 is provided with a second through groove 1012 for restricting the left and right movement of the left and right adjustment wheel 41. The second adjustment wheel is assembled in the second through groove 1012. The left and right adjustment member 42 is rotatably assembled with the left and right adjustment wheel 41. When the left and right adjustment wheel 41 rotates, the left and right adjustment member 42 moves left and right relative to the base 1. By setting the left and right adjustment wheel 41 to be assembled in the second through groove 1012 in the base 1, the left and right movement of the left and right adjustment wheel 41 in the left and right direction is restricted. When the left and right adjustment wheel 41 rotates, the left and right adjustment wheel 41 drives the left and right adjustment member 42 to move in the left and right direction, adjusting the left and right position of the drawer and the guide rail.
[0053] The left and right adjusting wheel 41 has a second screw hole through its middle. The left and right adjusting component 42 includes a second screw 421 threadedly connected to the second screw hole and a left and right adjusting block 422 connected to the left end of the second screw 421. The second screw 421 is threadedly rotatably assembled with the left and right adjusting wheel 41. When the left and right adjusting mechanism 4 is adjusted, the left and right adjusting wheel 41 is rotated, which drives the second screw 421 to move back and forth, so that the left and right adjusting block 422 adjusts the left and right position of the drawer and the guide rail.
[0054] The right end of the left and right adjustment block 422 is provided with an assembly part 4221 for detachable connection with the guide rail.
[0055] The base 1 is provided with a limiting part 13 that abuts against the upper left side and the lower left side of the adjusting block. The above-mentioned arrangement allows the left and right adjusting blocks 422 to move more smoothly. In addition to its guiding function, the limiting part 13 also supports the left and right adjusting blocks 422.
[0056] The assembly part 4221 includes forward-protruding and spaced-apart stop protrusions 4222 and stop grooves 4223. There are two sets of stop protrusions 4222, and the stop grooves 4223 are formed between the two sets of stop protrusions 4222 and are used for the insertion of the guide rail.
[0057] The upper and lower adjusting wheel 31, the left and right adjusting wheel 41, and the front and rear adjusting wheel 23 are provided with a plurality of adjusting teeth 6 on their outer periphery. The teeth increase the friction and facilitate manual adjustment by the operator.
[0058] The system also includes a locking mechanism 5. The base 1 has a second receiving cavity 102 for assembling the locking mechanism 5. The locking mechanism 5 includes a movable rotating member 51, a movable locking member 52, and a compression spring 53. The movable locking member 52 slides along the left and right direction of the base 1. The spring abuts against the movable locking member 52 and the inner sidewall of the base 1. The front end of the movable rotating member 51 extends into the second receiving cavity 102 and is assembled with the movable locking member 52. The rear end of the movable rotating member 51 protrudes from the base 1. The movable rotating member 51 rotates with the base 1. During assembly, when the movable rotating part 51 rotates to the left, the movable locking part 52 slides to the right and presses against the compression spring 53. When the movable rotating part 51 rotates to the right, the movable locking part 52 slides to the left and resets the compression spring 53. By rotating the movable rotating part 51 to the left, the movable locking part 52 can be moved to the right until it is completely housed in the second receiving cavity 102 and the spring is compressed, thus completing the guide rail disengagement function. By rotating the movable rotating part 51 to the right under the action of the spring reset and causing the movable locking part 52 to move to the left and protrude into the second receiving cavity 102, the guide rail connection function is completed.
[0059] The bottom wall of the movable card 52 is provided with a movable card slot 521, and the rear end of the movable rotating part 51 is assembled in the sliding card slot. By setting the movable card 52 and the movable card slot 521, the movable rotating part 51 and the movable card 52 can be linked together.
[0060] The base 1 has a downwardly protruding movable rotating column 14, and the movable rotating component 51 has a movable rotating hole 511 in the middle. The movable rotating column 14 is assembled in the movable rotating hole 511. By setting the movable rotating column 14 and the movable rotating hole 511, a support point is provided for the movement of the movable rotating component 51, thereby improving the stability of the movable rotating component 51 when it is moved.
[0061] The implementation principle of the two-section guide rail three-dimensional adjustment handle in this embodiment is as follows: In use, by rotating the left and right adjustment wheels 41, the left and right adjustment wheels 41 drive the left and right adjustment parts 42 to move left and right, adjusting the left and right positions of the guide rail and the drawer. At the same time, by rotating the front and rear adjustment wheels 23, the front and rear adjustment wheels 23 drive the front and rear adjustment parts 22 to move back and forth, thereby adjusting the front and rear positions of the guide rail and the drawer. In addition, by rotating the up and down adjustment wheels 31, the up and down adjustment parts 32 move back and forth, and the up and down positions of the guide rail and the drawer are changed by using the inclined part 3221. When the locking mechanism 5 is adjusted, the movable rotating part 51 rotates to the right, so that part of the movable locking part 52 extends out of the base 1 and engages with the guide rail, thereby locking the guide rail and the drawer. The movable rotating part 51 moves to the left, so that the movable locking part 52 moves into the second receiving cavity 102, thereby not engaging with the guide rail, and separating the guide rail and the drawer.
