Technical Field

[0001] This utility model relates to the field of RV technology, and more specifically, to a multi-stage telescopic device for RV kitchen countertops based on sliding rails. Background Technology

[0002] The kitchen countertop in an RV refers to the platform area inside the RV used for cooking operations. It provides a platform for cutting vegetables and cooking, and must meet the characteristics of corrosion resistance, high temperature resistance, and easy cleaning. It should be made of corrosion-resistant and high temperature-resistant materials (such as 304 stainless steel) to ensure that it will not deform after long-term use.

[0003] Some existing kitchen countertops with sliding rails require the countertop to be unfolded for use. However, once unfolded, the countertop cannot be stably fixed, causing it to wobble and affecting the user experience. Furthermore, the sliding rails can easily get stuck when damaged or deformed, further hindering the unfolding of the countertop.

[0004] Therefore, a multi-stage telescopic device for RV kitchen countertops based on sliding rails is proposed to address the above problems. Utility Model Content

[0020] Example 1

[0021] As attached Figures 1 to 4 The illustrated multi-stage telescopic device for a RV kitchen countertop based on sliding rails includes a base 1. Two first triangular sliding rails 3 are symmetrically arranged on the upper surface of the base 1. A first sliding block 6 is slidably connected to each of the two first triangular sliding rails 3. A first kitchen countertop 4 is fixedly connected between the two first sliding blocks 6. A second triangular sliding rail 8 is fixedly arranged on each of the two first triangular sliding rails 6. A second sliding block 7 is slidably connected to each of the two second triangular sliding rails 8. A second kitchen countertop 5 is fixedly arranged between the two second sliding blocks 7. A locking assembly is provided between the base 1 and the first sliding block 6, and between the first sliding block 6 and the second sliding block 7. A triangular groove 9 with a triangular cross-section is provided at the bottom of both the first sliding block 6 and the second sliding block 7.

[0022] In use, the locking components can be released from the first kitchen countertop 4 and the second kitchen countertop 5. Then, the first kitchen countertop 4 and the second kitchen countertop 5 can be slid open through the sliding connection between the first triangular slide rail 3 and the first slide block 6, and the second slide block 7 and the second triangular slide rail 8. At the same time, the locking components can be used to lock the slid-opened first kitchen countertop 4 and the second kitchen countertop 5. The first triangular slide rail 3, the second triangular slide rail 8, the first slide block 6, and the second slide block 7 are all slidably connected by a cross-sectional structure that is resistant to deformation. This prevents the kitchen countertop from getting stuck when it is opened due to deformation of the first triangular slide rail 3, the second triangular slide rail 8, and the triangular slide rail 9, thus improving the smoothness of the kitchen countertop sliding and opening.

[0023] Example 2

[0024] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0025] In a preferred embodiment, the locking assembly includes a limiting seat 10, a U-shaped locking rod 11, a stop 12, a connecting seat 13, and a locking spring 14. A plurality of limiting seats 10 are fixedly arranged at equal distances from the sidewall of a first slide block 6. A connecting seat 13 is fixedly arranged on one sidewall of both the first slide block 6 and the second slide block 7. A U-shaped locking rod 11 is inserted into the connecting seat 13. A stop 12 is fixedly arranged on one end of the U-shaped locking rod 11 located within the connecting seat 13. A connecting spring 14 is sleeved on the outer side of the U-shaped locking rod 11. There is a locking spring 14, and the other end of the U-shaped locking rod 11 is connected to the limiting seat 10. A hook 15 is fixedly installed on each of the two U-shaped locking rods 11. A layer of anti-slip rubber is sleeved on the outside of the hook 15. When locking the unfolded first kitchen countertop 4 and second kitchen countertop 5 through the locking assembly, the U-shaped locking rod 11 can be squeezed and moved by the cooperation of the stop block 12 and the locking spring 14, so that the other end of the U-shaped locking rod 11 is inserted into the limiting seat 10, which can complete the stable fixation of the unfolded kitchen countertop.

[0026] In a preferred embodiment, a gas stove 2 is installed on the upper surface of the base 1, and the gas stove 2 is located between two first triangular slide rails 3. A vegetable washing sink 16 is provided at one end of the base 1, and a drain pipe is connected to the bottom of the vegetable washing sink 16. The base 1 and the vegetable washing sink 16 are fixedly connected. Vegetables and fruits can be washed by the vegetable washing sink 16.

[0027] In a preferred embodiment, a limiting sliding component is provided between the first triangular slide rail 3 and the first slide block 6, and between the second slide block 7 and the second triangular slide rail 8. The limiting sliding component includes a limiting slider 17 and a limiting groove 18. A limiting groove 18 is provided on the side wall of the first triangular slide rail 3 and the second triangular slide rail 8. A limiting slider 17 that is slidably connected to the inner side wall of the triangular groove 9 provided on the bottom wall of the first slide block 6 and the second slide block 7 is fixedly connected to the limiting slider 17 that is slidably connected to the limiting groove 18. Through the limiting sliding connection between the limiting slider 17 and the limiting groove 18, the first kitchen countertop 4 and the second kitchen countertop 5 can be prevented from detaching and falling off during the sliding unfolding process, and the stability of the first kitchen countertop 4 and the second kitchen countertop 5 when sliding unfolding can be improved.

[0028] The working process of this utility model is as follows: First, when using it, the U-shaped locking rod 11 can be pulled to release the locking component from locking the first kitchen countertop 4 and the second kitchen countertop 5. Then, the first kitchen countertop 4 and the second kitchen countertop 5 can be slid open through the sliding connection between the first triangular slide rail 3 and the first slide block 6, and between the second slide block 7 and the second triangular slide rail 8. Then, the U-shaped locking rod 11 is released. At this time, the stop block 12 compresses the locking spring 14, and the compressed locking spring 14 drives the U-shaped locking rod 11 to move, thereby causing the other end of the U-shaped locking rod 11 to insert into the limiting device. Within the seat 10, the unfolded kitchen countertop can be stably fixed, locking the first kitchen countertop 4 and the second kitchen countertop 5 that slide out. At the same time, the first triangular slide rail 3, the second triangular slide rail 8, and the triangular slide grooves 9 on the first slide block 6 and the second slide block 7 are all slidably connected by a deformation-resistant cross-sectional structure, preventing the kitchen countertop from getting stuck during unfolding due to deformation of the first triangular slide rail 3, the second triangular slide rail 8, and the triangular slide grooves 9, thus improving the smoothness of the kitchen countertop's sliding unfolding. The above is the working principle of this multi-stage telescopic device for RV kitchen countertops based on slide rails.
