Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicle ladders, in particular to a recreational vehicle ladder. Background Art

[0002] In the current RV market, as a special vehicle that combines living and travel functions, the design and configuration of RVs are increasingly attracting attention and attention from consumers. RV ladders are important auxiliary facilities that connect the RV floor to the roof or the top of the vehicle. Their convenience, safety, and flexibility are crucial to improving the user experience.

[0003] However, RV ladders currently on the market generally use a fixed mounting mechanism to mount the ladder on the RV, and the fixed connection between the mounting mechanism and the ladder cannot be adjusted. This fixed mounting seat design also has certain limitations in the manufacture and installation process of the ladder. Due to the inability to flexibly adjust, manufacturers need to pre-set the height of the mounting mechanism on the ladder according to different RV structures during production to avoid windows or other accessories on the rear wall of the vehicle body, or set the angle of the mounting mechanism according to the direction of the square tubes on the rear wall of the vehicle body (such as horizontally arranged square tubes, vertically arranged square tubes, or two parallel square tubes). This limits the versatility and adaptability of the product to a certain extent. Utility Model Content

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] like Figures 1 to 8 As shown, embodiment 1 is a RV ladder, comprising a ladder body 1 and a spare tire rack 2; the spare tire rack 2 is connected to a first vertical rod 11 on one side of the ladder body 1, and a plurality of mounting mechanisms 3 are provided on the first vertical rod 11, the mounting mechanism 3 comprising a fixing seat 31 and a locking ring 32, two first screw holes 311 are symmetrically provided on the fixing seat 31, the locking ring 32 is rotatably connected to the fixing seat 31, the locking ring 32 is sleeved on the first vertical rod 11, and the locking ring 32 can be adjusted and moved between two adjacent pedals 12 of the ladder body 1.

[0027] When installing the ladder body 1, first basically fix the spare tire rack 2 to the ladder body 1, and then firmly fix the ladder body 1 through the installation mechanism 3. During the installation process of the installation mechanism 3, the height of the installation mechanism 3 can be adjusted according to the spacing distance of the square tubes 4 on the rear wall of the RV by moving the locking ring 32, while avoiding the windows or accessory decorations on the rear wall of the RV to avoid interference with the installation point. In addition, by rotating the locking ring 32, the angle of the fixing seat 31 can also be adjusted according to the arrangement direction of the square tube 4, so as to adapt to the vertically arranged square tube 4, the horizontally arranged square tube 4 and two parallel arranged square tubes 4, which makes the installation more flexible and more adaptable.

[0028] Example 2: This example is a further improvement on Example 1, and its details are as follows:

[0029] The spare tire rack 2 includes a C-shaped frame 21 and a spare tire mounting member 22 connected to the C-shaped frame 21. Both ends of the C-shaped frame 21 are connected to the first vertical rod 11. The C-shaped frame 21 is fixed to the rear wall of the RV via a mounting mechanism 3, and the spare tire mounting member 22 is located in the middle of the rear wall. Positioning the spare tire rack 2 to the side of the ladder body 1 does not interfere with the normal use of the ladder body 1, and the position of the spare tire rack 2 does not need to be adjusted during climbing, which is more convenient. Furthermore, the spare tire rack 2 is positioned to the side of the ladder body 1. Since the ladder is light in weight and does not affect the balance of the RV, while the spare tire is heavier, its location in the middle of the RV during installation significantly reduces any impact on the RV's balance.

[0030] Example 3: This example is a further improvement on Example 2, and its details are as follows:

[0031] The spare tire rack 2 further includes a reinforcing rod 23, the two ends of which are adjustably mounted on the first vertical rod 11 and the second vertical rod 211 of the C-shaped rack 21 through locking rings 32, so that the spare tire rack 2 is more firmly fixed and safer.

[0032] Example 4: This example is a further improvement on Example 3, and its details are as follows:

[0033] The crossbar 212 and the second vertical bar 211 of the C-shaped frame 21 are both provided with a mounting mechanism 3. Multiple-point fixation improves the load-bearing capacity of the spare tire rack 2.

[0034] Example 5: This example is a further improvement based on any one of Examples 1 to 4, and its details are as follows:

[0035] The mounting mechanism 3 further includes a connecting rod 33, one end of which is provided with an annular limiting groove 331 on its peripheral wall. A connecting hole 321 is provided on one side of the locking ring 32, and a limiting ring 322 adapted to the annular limiting groove 331 is provided on the inner peripheral wall of the connecting hole 321.

[0036] One end of the connecting rod 33 is fixedly connected to one side of the fixing seat 31, and the other end is rotatably disposed within the connecting hole 321. The limiting ring 322 is located within the annular limiting groove 331. This allows the fixing seat 31 to rotate 360 ​​degrees relative to the locking ring 32. The annular limiting groove 331 and the limiting ring 322 prevent the fixing seat 31 from separating from the locking ring 32. In a specific embodiment, the central axis of the rotation direction of the connecting rod 33 intersects and is perpendicular to the central axis of the first vertical rod 11 of the ladder body 1. When the first vertical rods 11 on both sides of the ladder body 1 are fixed by the mounting mechanism 3, there is motion interference between the fixing seat 31, the connecting rod 33, and the locking ring 32, preventing rotation, thereby fixing the position of the ladder body 1.

[0037] Example 6: This example is a further improvement based on any one of Examples 1 to 5, and its details are as follows:

[0038] A second screw hole 323 is formed through the locking ring 32, and a bolt is connected to the inner thread of the second screw hole 323, and the inner end of the bolt abuts against the first vertical rod 11. It is only necessary to lock or unlock with the bolt, which makes adjustment more convenient.

[0039] Example 7: This example is a further improvement based on any one of Examples 1 to 6, and its details are as follows:

[0040] The upper end surface of the pedal 12 is provided with anti-skid grooves to avoid slipping when climbing the ladder body 1.

[0041] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
