Description

Technical Field

[0001] The utility model relates to the technical field of garden maintenance, in particular to a telescopic garden ladder. Background Art

[0002] A garden ladder is a tool specially used for landscaping maintenance. It can provide a stable working platform for gardeners so that they can reach the height of trees for pruning and maintenance work. However, due to the different heights of trees, traditional fixed-height ladders cannot adapt to different working conditions, so telescopic garden ladders are needed to adapt to different working heights and environments. At the same time, telescopic garden ladders can also be retracted to a shorter size when not needed, which is easy to carry and store, improving work efficiency and convenience.

[0003] According to the search, the Chinese patent document, announcement number: CN207892516U, discloses a telescopic garden ladder, which moves the elevator upward along the slideway by pulling the rope passing through the pulleys. During the upward movement of the elevator, the clamping block will hit the crossbar. At this time, the slope of the clamping block will conflict with the crossbar, causing it to swing back and forth along the hinge point. After a certain period of time, it will return to its original position due to gravity. When the elevator rises to an appropriate height, the clamping groove is clamped on the crossbar, and the rope is tied to the fixed ladder, thereby completing the adjustment of the garden ladder body. However, the device needs to continuously pull the rope during actual use, which is inconvenient to adjust, and the connection between the clamping groove and the crossbar is not very stable, which reduces the overall practicality. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a telescopic garden ladder, which has the advantages of easy adjustment, stable structure, and improved overall work efficiency and convenience, thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a telescopic garden ladder comprises a first ladder leg, a first pedal and a connecting seat are fixedly installed on the outer side surface of the first ladder leg, a sliding groove is provided inside the first ladder leg, a second ladder leg is slidably installed inside the sliding groove, a second pedal is fixedly installed on the outer side surface of the second ladder leg, a ladder cap is fixedly installed on the top end of the second ladder leg, a connector is installed on the top end of the ladder cap, a first limiting groove is provided inside the connecting seat, a spring and a connecting rod are installed inside the first limiting groove, a handle is fixedly installed on the left end of the connecting rod, a limiting block is fixedly installed on the right end of the connecting rod, a support is fixedly installed on the bottom end of the first ladder leg, a rotating shaft is installed inside the support, and a supporting seat is installed on the outer side surface of the rotating shaft.

[0008] Preferably, the number of the first ladder legs is set to four, and the number of the first pedals is set to multiple.

[0009] Through the above technical solution, multiple first pedals can not only be used by the staff for standing and climbing, but also connect the four first ladder legs in pairs, ensuring the stability and integrity of the garden ladder.

[0010] Preferably, the number of the sliding grooves, the second ladder legs and the ladder caps is all set to four, the number of the second pedals is set to multiple, and the number of the connectors is set to two.

[0011] Through the above technical solution, multiple second pedals can connect the four second ladder legs in pairs. At the same time, parts such as the four second ladder legs can be connected into a whole through the ladder caps and the connectors. Then, by sliding the four second ladder legs inside the four sliding grooves respectively, the overall height of the garden ladder can be effectively adjusted. In addition, the opening and closing angle of the garden ladder can be adjusted through the two connectors, improving the overall practicability of the device.

[0012] Preferably, the number of the connection seats, the first limiting grooves, the springs, the connecting rods, the handles and the limiting blocks is all set to four, and one end of the spring far away from the handle is fixedly connected to the left side surface of the limiting block.

[0013] Through the above technical solution, by pulling the handle outwards, the handle can drive the connecting rod and the limiting block to move inside the first limiting groove. When the limiting block moves outwards, the position of the second ladder leg can be adjusted, and at the same time, the spring will be compressed; when the handle is released, parts such as the limiting block can move inwards under the reaction force of the spring, thereby restricting the position of parts such as the second ladder leg. Therefore, the convenience and working efficiency of the staff adjustment can be effectively improved.

[0014] Preferably, a plurality of second limiting grooves are formed on the outer side surfaces of the four second ladder legs, and the four limiting blocks are respectively installed inside four of the second limiting grooves.

[0015] Through the above technical solution, when pulling the handle, the handle can drive the limiting block to leave the inside of the second limiting groove. At this time, the second ladder leg can be slid to adjust the overall height of the garden ladder; after the adjustment is completed and the handle is released, the limiting block can move into the corresponding second limiting groove under the reaction force of the spring, thereby restricting the position of the second ladder leg and improving the overall stability and convenience of the device.

[0016] Preferably, the number of the supports, the rotating shafts and the supporting seats is all set to four.

[0017] With the above technical solution, when the garden ladder is at different opening and closing angles, the four support seats can respectively rotate on the outer sides of the four rotating shafts. Therefore, it can effectively fit the ground to maintain stability. At the same time, the support seats can also increase the contact area with the ground to improve the friction force, further enhancing the overall stability of the device.

[0018] Compared with the prior art, the present utility model provides a telescopic garden ladder, which has the following beneficial effects:

[0019] 1. With the multiple first pedals and second pedals of the present utility model, not only can the staff stand and climb, but also the four first ladder legs and the second ladder legs can be connected in pairs, ensuring the stability and integrity of the device; the four second ladder legs and other parts can be connected together through the ladder caps and connectors. The opening and closing angle of the garden ladder can be adjusted through two connectors, improving the overall practicality of the device; in addition, when the garden ladder is at different opening and closing angles, the four support seats can respectively rotate on the outer sides of the four rotating shafts. Therefore, it can effectively fit the ground to maintain stability. At the same time, the support seats can also increase the contact area with the ground to improve the friction force, further enhancing the overall stability of the device.

[0020] 2. By pulling the four handles outward, the handles can drive the connecting rods and the limit blocks to move inside the first limit grooves. When the limit blocks leave the inside of the second limit grooves, the springs can be compressed. At the same time, by sliding the four second ladder legs respectively inside the four chutes, the overall height of the garden ladder can be adjusted; after the adjustment is completed, release the handles, and the limit blocks can move to the corresponding second limit grooves under the reaction force of the springs, thereby restricting the positions of the second ladder legs and other parts, effectively improving the convenience and working efficiency of the staff's adjustment.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-4 , a telescopic garden ladder, including a first ladder leg 1, a first pedal 2 and a connecting seat 3 are fixedly installed on the outer side surface of the first ladder leg 1, a sliding groove 4 is opened inside the first ladder leg 1, a second ladder leg 5 is slidably installed inside the sliding groove 4, a second pedal 6 is fixedly installed on the outer side surface of the second ladder leg 5, a ladder cap 7 is fixedly installed at the top end of the second ladder leg 5, a connector 8 is installed at the top end of the ladder cap 7, a first limiting groove 9 is opened inside the connecting seat 3, a spring 10 and a connecting rod 11 are installed inside the first limiting groove 9, a handle 12 is fixedly installed at the left end of the connecting rod 11, a limiting block 13 is fixedly installed at the right end of the connecting rod 11, a support 14 is fixedly installed at the bottom end of the first ladder leg 1, a rotating shaft 15 is installed inside the support 14, and a support seat 16 is installed on the outer side surface of the rotating shaft 15.

[0028] Specifically, the number of the first ladder legs 1 is set to four, and the number of the first pedals 2 is set to multiple. The advantage is that through this structure, multiple first pedals 2 can not only be used by the staff for standing and climbing, but also connect the four first ladder legs 1 in pairs, ensuring the stability and integrity of the garden ladder.

[0029] Specifically, the numbers of the sliding groove 4, the second ladder leg 5 and the ladder cap 7 are all set to four, the number of the second pedals 6 is set to multiple, and the number of the connectors 8 is set to two. The advantage is that through this structure, multiple second pedals 6 can connect the four second ladder legs 5 in pairs, and at the same time, four second ladder legs 5 and other parts can be connected into a whole through the ladder cap 7 and the connector 8. Then, by sliding the four second ladder legs 5 inside the four sliding grooves 4 respectively, the overall height of the garden ladder can be effectively adjusted. In addition, the opening and closing angle of the garden ladder can be adjusted through the two connectors 8, improving the overall practicability of the device.

[0030] Specifically, the connecting seat 3, the first limiting groove 9, the spring 10, the connecting rod 11, the handle 12, and the limiting block 13 are all provided in four numbers, and the end of the spring 10 away from the handle 12 is fixedly connected to the left side surface of the limiting block 13. The advantage is that by pulling the handle 12 outward, the handle 12 can drive the connecting rod 11 and the limiting block 13 to move inside the first limiting groove 9. When the limiting block 13 moves outward, the position of the second ladder leg 5 can be adjusted, and at the same time, the spring 10 will be compressed; when the handle 12 is released, parts such as the limiting block 13 can move inward under the reaction force of the spring 10, thereby restricting the positions of parts such as the second ladder leg 5.

The advantage is that with this structure, when the garden ladder is at different opening and closing angles, the four support seats 16 can respectively rotate on the outer side surfaces of the four rotating shafts 15. Therefore, it can effectively fit the ground to maintain stability. At the same time, the support seats 16 can also increase the contact area with the ground to improve the friction force, further improving the overall stability of the device.
