[0026] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0027] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 6As shown, a slide protection structure provided by an embodiment of the utility model includes a support frame 1, a slider 2 is slidably installed on the upper part of the support frame 1, a first screw rod 3 is rotatably installed on the upper part of the support frame 1, the first screw rod 3 is externally screwed to the slider 2, a motor 5 is fixedly installed on the upper part of one side of the support frame 1, a linkage rod 6 is fixedly connected to the output end of the motor 5, a protection component 7 is fixedly connected to the end of the linkage rod 6 away from the motor 5, and the protection component 7 is transmission-connected to the first screw rod 3 through a gear set 8; the protection component 7 includes an inner connecting column 702, one side of the inner connecting column 702 is fixedly connected to the linkage rod 6, a plurality of elastic telescopic rods 703 are fixedly installed on the outside of the inner connecting column 702, an outer connecting tube 701 for connecting to the gear set 8 is rotatably installed on the outside of the inner connecting column 702, a card slot 704 is opened inside the outer connecting tube 701, and the elastic telescopic rod 703 is movably inserted into the card slot 704.

[0029] The above-mentioned slide protection structure is mainly composed of a support frame 1, a slider 2, a first screw rod 3, a motor 5 and a unique protection component 7. The slider 2 is slidably mounted on the support frame 1, and the slider 2 is connected to the motor 5 through the first screw rod 3 to achieve power transmission and precise control of the position of the slider 2. The motor 5 is connected to the protection component 7 through a linkage rod 6, and the protection component 7 is connected to the first screw rod 3 through a gear set 8, forming a complete power and protection system.

[0030] The protection component 7 is the core part of the present design, and is composed of an inner connecting column 702, an elastic telescopic rod 703, and an outer connecting tube 701. The inner connecting column 702 is fixedly connected to the linkage rod 6 to ensure the stability and accuracy of power transmission. A number of elastic telescopic rods 703 are fixedly installed outside the inner connecting column 702. These telescopic rods remain in an extended state when the slider 2 moves normally, and when the slider 2 approaches the end of the stroke, the telescopic rods will retract due to the torque of the motor 5, thereby protecting the slider 2.

[0031] Specifically, the outer connecting tube 701 is rotatably mounted on the outside of the inner connecting column 702, and a slot 704 is provided inside to accommodate the elastic telescopic rod 703. When the slider 2 moves to the end of the stroke, the elastic telescopic rod 703 will retract into the slot 704 under the action of the torque of the motor 5, so that the motor 5 enters an idling state, thereby preventing the slider 2 from being squeezed and contacted with the support frame 1, and effectively protecting the slider 2 and the support frame 1 from damage.

[0032] In this embodiment, two slide bars 4 are fixedly connected to the upper part of the support frame 1, and the outer parts of the two slide bars 4 are slidably connected to the slider 2. The gear set 8 includes a third bevel gear 801, and the third bevel gear 801 is meshedly connected with a bevel gear ring 802. The inner side of the bevel gear ring 802 is fixedly connected to the outer connecting tube 701, and one side of the third bevel gear 801 is fixedly connected to the first screw rod 3, and the bevel gear ring 802 is rotatably mounted on the upper part of one side of the support frame 1.

[0033] The upper part of the support frame 1 is not only equipped with a screw to drive the slider 2, but also with two slide bars 4, which form a stable sliding connection with the slider 2. The existence of the slide bar 4 not only provides additional support for the slider 2, but also ensures the stability and accuracy of the slider 2 during movement. The cooperation between the slide bar 4 and the slider 2 enables the slider 2 to move accurately along a predetermined trajectory under the drive of the screw, effectively reducing the displacement or shaking of the slider 2 caused by external force or vibration.

[0034] In the design of the gear set 8, the meshing connection mode of the third bevel gear 801 and the bevel gear ring 802 is adopted. This design not only improves the transmission efficiency of the gear set 8, but also makes the entire transmission process more stable and reliable. One side of the third bevel gear 801 is tightly fixed to the first screw 3, ensuring that the power can be accurately transmitted to the gear set 8 when the screw rotates. The bevel gear ring 802 is fixed to the inner side of the external connecting tube 701. When the external connecting tube 701 rotates, the bevel gear ring 802 will also rotate, thereby realizing the meshing transmission with the third bevel gear 801.

[0035] The bevel gear ring 802 is installed on the upper part of one side of the support frame 1. This design is not only easy to install and disassemble, but also provides stable support for the entire gear set 8. Through the meshing of the bevel gear ring 802 and the third bevel gear 801, we can achieve power transmission between the screw and the external connecting tube 701, and then control the movement of the slider 2. This design not only improves the overall performance of the slide protection structure, but also provides a strong guarantee for its stability and reliability in practical applications.

[0036] In this embodiment, the elastic telescopic rod 703 includes a fixed tube 7031, a slide plate 7034 is slidably installed inside the fixed tube 7031, the upper part of the slide plate 7034 is connected to a round-headed clamping rod 7032 through a spring 7033, the round-headed clamping rod 7032 is movably inserted into the clamping slot 704, the outside of the round-headed clamping rod 7032 is slidably connected to the fixed tube 7031, and the fixed tube 7031 is fixed to the outside of the connecting column. An adjusting member 705 is also provided inside the connecting column, and the adjusting member includes a transmission rod 7052, which is rotatably installed inside the connecting column, one end of the transmission rod 7052 extends through the connecting column to the outside and is fixedly connected to a turntable 7051, and the other end of the transmission rod 7052 is fixedly connected to a first bevel gear 7053, and the first bevel gear 7053 is meshingly connected to a second bevel gear 7054, and the second bevel gear 7054 is rotatably installed inside the connecting column, and a second screw rod 7055 is fixedly connected to the upper part of the second bevel gear 7054, and the upper part of the second screw rod 7055 passes through the fixed tube 7031 and is screwed to the slide plate 7034.

[0037] In the design of the elastic telescopic rod 703 of the slide protection structure, a convenient initial pressure adjustment mechanism of the spring 7033 is introduced. The core of this mechanism lies in the adjustment part inside the connecting column, especially the rotating disk 7051 outside it.

[0038] The rotating disk 7051 is closely connected with the transmission rod 7052, and the rotation control of the transmission rod 7052 can be realized by a simple rotation operation. The other end of the transmission rod 7052 is connected with the first bevel gear 7053, and then the second bevel gear 7054 and the second screw rod 7055 are driven to rotate through the meshing transmission of the bevel gears.

[0039] The second screw rod 7055 is threadedly connected to the slide plate 7034. When the transmission rod 7052 rotates, the second screw rod 7055 converts the rotational motion into the linear motion of the slide plate 7034. The upper part of the slide plate 7034 is connected to the round head clamping rod 7032 through the spring 7033. Therefore, the movement of the slide plate 7034 directly affects the compression degree of the spring 7033, thereby changing the initial pressure of the spring 7033.

[0040] This design allows the operator to conveniently and accurately adjust the initial pressure of the spring 7033 by rotating the turntable 7051. According to the torque of the motor 5, the operator can timely adjust the initial tension of the spring 7033 to ensure that when the slider 2 approaches the end of the stroke, the spring 7033 can provide sufficient resilience to make the motor 5 idle, thereby preventing the slider 2 from extruding and contacting with the support frame 1. Through this mechanism, not only the safety and reliability of the slide protection structure are improved, but also a more flexible and convenient operation experience is provided for the user.

[0041] The working principle of this utility model:

[0042] A slider 2 is slidably mounted on the support frame 1, and the slider 2 is connected to the motor 5 through the first screw rod 3 to achieve precise control of power transmission and the position of the slider 2. The motor 5 is connected to the protection component 7 through the linkage rod 6, and the protection component 7 is connected to the first screw rod 3 through the gear set 8 to form a complete power and protection system. The protection component 7 is the core part of this design. The inner connecting column 702 is fixedly connected to the linkage rod 6 to ensure the stability and accuracy of power transmission. Several elastic telescopic rods 703 are fixedly mounted on the outside of the inner connecting column 702. These telescopic rods remain in an extended state when the slider 2 moves normally, and when the slider 2 approaches the end of the stroke, due to the torque of the motor 5, the telescopic rod will retract to protect the slider 2. Specifically, the outer connecting tube 701 is rotatably mounted on the outside of the inner connecting column 702, and a slot 704 is provided inside to accommodate the elastic telescopic rod 703. When the slider 2 moves to the end of its travel, the elastic telescopic rod 703 will retract into the slot 704 under the action of the torque of the motor 5, so that the motor 5 enters an idling state, thereby avoiding compression contact between the slider 2 and the support frame 1, and effectively protecting the slider 2 and the support frame 1 from damage.
