Description

Technical Field

[0001] The utility model mainly relates to the technical field of switch handles, and particularly relates to a spiral handle. Background Art

[0002] At present, most of the handles of drawers only play the role of pulling force. However, in the vehicle drawer system, since the vehicle is in motion most of the time, it is necessary to set a limiting component to limit the drawer to prevent the drawer from being vibrated and ejected during the movement of the vehicle, resulting in safety failures.

[0003] For example, a pulling and unlocking device with the patent number 2024203970117 includes a pulling handle, and an unlocking switch is arranged at the bottom of the pulling handle, which plays the role of moving and controlling the switch; the unlocking switch cooperates with the pulling handle to play a role in pulling and resetting the cable limiting structure; the cable limiting structure is provided with a telescopic limiting pin at the end, and reciprocally moves the telescopic limiting pin in cooperation with the unlocking switch.

[0004] The inventor found the following defects during the operation of specific embodiments:

[0039] Refer to the attached Figures 1-5 , a spiral handle, comprising

[0040] A support frame 1, which is arranged on one side of the drawer body;

[0041] A rotary reset handle 2, the end of the rotary reset handle 2 is rotatably connected to the inside of the support frame 1 to play a switching role;

[0042] A spiral part 3, the spiral part 3 passes through the inside of the support frame 1, both ends of the spiral part 3 are matched and connected to the rotary reset handle 2, a threaded chute 4 is arranged thereon, the threaded chute 4 is slidably connected to a sliding part 5, and the sliding part 5 is connected to a telescopic limit pin 6.

[0043] Please refer particularly to Figures 1-2 , this device needs to be used in cooperation with the telescopic limit pin 6. One end of the telescopic limit pin 6 is connected to the corresponding slide rail. When the telescopic limit pin 6 is stretched by the rotary reset handle 2, the drawer can be pulled open. When the telescopic limit pin 6 is reset, the drawer will be locked. This part is the prior art and will not be elaborated here. The support frame 1 of this device is connected to the sliding drawer by screws. When the drawer needs to be pulled open, pull the rotary reset handle 2 outwards. Since the rotary reset handle 2 is connected to the spiral part 3, the spiral part 3 will also rotate a certain angle following the rotary reset handle 2. The sliding part 5 is slidably connected to the threaded chute 4. The rotation of the threaded chute 4 will cause the sliding part 5 to slide up and down, thereby driving the telescopic limit pin 6 to stretch, and the drawer can be pulled open. When the rotary reset handle 2 is released, the spiral part 3 rotates in the reverse direction, thereby driving the sliding part 5 to reset, and the drawer is limited and stops sliding. The overall structure of this device is compact, with few components, and is more stable to use.

[0044] Please refer particularly to Figures 1-2 , on one side of the top of the support frame 1, rotating grooves 11 are symmetrically opened. The rotary reset handle 2 is rotatably connected in the rotating grooves 11. The arrangement of the rotating grooves 11 facilitates the outward pulling of the rotary reset handle 2, thereby driving the movement of the sliding part 5.

[0045] Please refer particularly to Figure 4 , on the inner side of the support frame 1, support plates 12 are symmetrically arranged. Circular holes 13 are opened on the support plates 12. A support washer 14 is connected in the circular holes 13. The spiral part 3 is rotatably connected on one side of the support washer 14, and the rotary reset handle 2 is arranged on the other side of the support washer 14. When the rotary reset handle 2 rotates, its bottom will rotate around the support washer 14 of the support plate 12, thereby driving the spiral part 3 to rotate around the support washer 14.

[0046] Please refer particularly to Figure 4, a concave connecting groove 21 is provided at the end of the rotary reset handle 2, the two ends of the spiral part 3 are clamped by the concave connecting groove 21, a toggle rod 22 is provided outside the concave connecting groove 21, and the bottom of the toggle rod 22 is connected to a reset mechanism 23. The concave connecting groove 21 is clamped with the two ends of the spiral part 3, so that the spiral part 3 can be rotated well. After the rotary reset handle 2 is pulled outwards, the reset mechanism 23 can quickly reset the rotary reset handle 2, so that the telescopic limit pin 6 is inserted into the slide rail again to form a positioning. There is a locking screw outside the toggle rod 22, and the toggle rod 22 is connected to the spiral shaft 31 through a gasket, so as to lock the concave connecting groove 21, which is convenient for the rotation and unlocking of the rotary reset handle. The locking screw is not shown in the figure.

The elastic member 233 can be made of elastic materials such as springs and elastic rubber plates. When the rotary reset handle 2 needs to be toggled outwards, the toggle rod 22 will squeeze the elastic member 233. After the rotary reset handle 2 is pulled and toggled, the elastic member 233 plays a role in quickly resetting the toggle rod 22.

[0048] Please refer to Figure 4 , the spiral part 3 includes a spiral shaft 31, a threaded sliding groove 4 is opened on the spiral shaft 31, two rotating protrusions 32 are connected to both ends of the spiral shaft 31, and the rotating protrusions 32 are clamped with the concave connecting groove 21. When the spiral shaft 31 rotates, it will drive the threaded sliding groove 4 on its surface to rotate, thereby driving the sliding part 5 to move in the threaded sliding groove 4. The rotating protrusions 32 are clamped with the end of the rotary reset handle 2, which is convenient for the rotary reset handle 2 to drive it to rotate.

[0049] Please refer to Figure 3 , the sliding part 5 includes a concave slide rail 51, a sliding raceway 52 is provided in the concave slide rail 51, the sliding raceway 52 is connected to a moving block 54 through a first sliding ball 53, two support blocks 55 matching the threaded sliding groove 4 are symmetrically provided at the top of the moving block 54, and a second sliding ball 56 is provided between the two support blocks 55. The moving block 54 can slide in the sliding raceway 52. The first sliding ball 53 and the second sliding ball 56 can reduce the friction when the moving block 54 slides. When the threaded sliding groove 4 at the top rotates, the moving block 54 will also move in the concave slide rail 51 following the rotation of the threaded sliding groove 4. It should be noted that in this embodiment, only the sliding ball is used for sliding as an example, which is convenient for the moving block 54 to slide in the concave slide rail 51. The sliding part 5 connected by other types of slide rails and sliders is also within the protection scope of this application.

[0050] Please refer to with emphasis Figure 2 , a positioning block 511 is provided on the side of the concave slide rail 51, and the telescopic limit pin 6 is clamped on the side of the positioning block 511. After the telescopic limit pin 6 is clamped with the positioning block 511, the internal telescopic pull rope is connected to the moving block 54, and then the telescopic pull rope is driven to perform the limiting and unlocking operations through the movement of the moving block 54.

[0051] Please refer to with emphasis Figure 5 , a connecting frame 512 is provided on the side of the concave slide rail 51. A second threaded hole 513 is opened at the bottom of the connecting frame 512 for detachably connecting with the support frame 1. The hollow design of the connecting frame 512 can reduce the weight of the concave slide rail 51. When the concave slide rail 51 needs to be installed, place it on the inner floor of the connecting frame 512 and connect it with screws.

[0052] The above embodiments only represent a certain implementation manner of the present invention, and its description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
