Detailed Description

The present application is described in further detail below with reference to figures 1-6.

The first embodiment is as follows:

the embodiment of the application discloses portable book ladder. Referring to fig. 1 and 2, the bookcase 15 is provided with a moving assembly 2 in order to facilitate the ladder 1 to move on the bookcase 15, the moving assembly 2 comprises a moving guide rail 21 fixed along the length direction of the bookcase 15, a rack 22 fixed on the inner wall of the moving guide rail 21, an adjusting part 23 arranged on the ladder 1 and a gear 24 arranged on the adjusting part 23, the rack 22 is arranged along the length direction of the inner wall of the moving guide rail 21, and the gear 24 is meshed with the rack 22. The ladder 1 can move along the moving guide rail 21, and the times of adjusting the ladder 1 up and down by people are effectively reduced.

Referring to fig. 2 and 3, in order to reduce the friction force generated by the ladder 1 to the ground in the moving process, a first roller 3 is fixed at the bottom end of the ladder 1, and the first roller 3 effectively reduces the friction force generated between the ladder 1 and the ground, so that the ladder 1 can move conveniently. Be fixed with handrail 14 in one side of ladder 1 climbing, handrail 14 sets up along ladder 1 length direction, and the people of being convenient for use handrail 14 when the climbing improves the security of ladder 1 in the use.

Referring to fig. 3 and 4, the ladder 1 is adjusted by the adjusting member 23 when the angle needs to be adjusted during use. The adjusting part 23 comprises an adjusting track 231 arranged at the upper end of the ladder 1 and arranged along the length direction of the ladder 1, an adjusting block 232 arranged in the adjusting track 231 and a motor 233 fixed in the adjusting block 232, the output end of the motor 233 is fixedly connected with the gear 24, the motor 233 drives the gear 24 to rotate, and the gear 24 rotates to drive the ladder 1 to move along the length direction of the rack 22. An installation ear 4 for installing the adjusting rail 231 is fixed on the upper end of the ladder 1, and a rotating shaft 5 positioned in the installation ear 4 is fixed on the adjusting rail 231. In order to improve the stability of the adjusting block 232 in the adjusting track 231, the inner wall of the adjusting track 231 is provided with a limiting groove 6, and a limiting block 7 located in the limiting groove 6 is fixed on the adjusting block 232. When ladder 1 needs angle regulation, ladder 1 rotates through pivot 5, because ladder 1 needs the conflict bottom surface, when 1 bottom of ladder and bottom surface contact, ladder 1 can stimulate regulation track 231 and move down, and the gyro wheel of being convenient for 3 contact ground improves ladder 1 stability in the accommodation process.

Referring to fig. 3 and 4, after the angle adjustment of the ladder 1 is completed, the possibility of the adjustment rail 231 moving down is reduced in order to improve the stability of the ladder 1 during use. The telescopic rods 8 are arranged on two sides of the ladder 1 in the length direction, universal joints 10 connected with the telescopic rods 8 are fixed on the ladder 1, and the universal joints 10 facilitate the telescopic rods 8 to rotate in multiple directions. A positioning buckle 9 is fixed on the ladder 1, the positioning buckle 9 is an arc-shaped elastic buckle, and when the telescopic rod 8 is not used, the telescopic rod 8 is embedded into the positioning buckle 9; when the telescopic rod 8 needs to be used, the telescopic rod 8 is directly pulled out of the positioning buckle 9. The telescopic link 8 includes that one end is established interior pole 81 and the cover of universal joint 10 and is established the outer tube 82 outside interior pole 81, and guide way 12 has been seted up along length direction to interior pole 81, is equipped with the positioning bolt 13 that is located guide way 12 on the outer tube 82, offers the screw hole that is used for installing positioning bolt 13 on the outer tube 82, after adjusting the length of telescopic link 8, screws up interior pole 81 of positioning bolt 13 butt, improves the stability of interior pole 81 and outer tube 82. Because the telescopic rod 8 needs to move along with the ladder 1, the second roller 11 is fixed at the bottom end of the outer tube 82, and the second roller 11 effectively reduces the friction force between the outer tube 82 and the ground.

The implementation principle of the movable book ladder in the embodiment of the application is as follows: when ladder 1 is required to move, motor 233 is started, motor 233 drives gear 24 to rotate, gear 24 rotates, ladder 1 is driven to move along the length direction of rack 22, roller 3 is convenient for ladder 1 to move, and friction between ladder 1 and the ground is effectively reduced.

When the ladder 1 needs to be adjusted in angle, the ladder 1 is rotated through the rotating shaft 5, the adjusting track 231 is pulled, the length of the ladder 1 is prolonged, the first rolling wheels 3 are convenient to contact with the ground, and the stability of the ladder 1 is improved. The telescopic rod 8 is pulled out of the positioning buckle 9, the telescopic rod 8 is rotated by the universal joint 10, the telescopic rod 8, the ground and the ladder 1 form a stable triangular structure, and the stability of the ladder 1 in the using process is improved. The second rollers 11 effectively reduce the friction force between the outer tube 82 and the ground, so that the ladder 1 can move conveniently.

Example two:

the difference between the second embodiment of the present application and the first embodiment is that, referring to fig. 5 and 6, the moving assembly 2 includes a moving rod 25 fixedly mounted along the length direction of the top end of the ladder 1, a positioning hook 26 hung on the moving rod 25, and positioning blocks 27 fixedly mounted on both sides of the ladder 1 in the length direction, in order to facilitate the connection between the positioning hook 26 and the positioning blocks 27, a sliding groove 261 is formed in the positioning hook 26 along the length direction, and a slider 271 located in the sliding groove 261 is fixed on the positioning block 27. When the ladder 1 rotates for use, the positioning hook 26 rotates by a certain angle, the ladder 1 needs to be pulled downwards to contact the ground, and the sliding block 271 slides in the sliding groove 261, so that the ladder 1 can be conveniently used.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
