Description

Technical Field

[0001] This invention relates to the field of buildings, and more specifically, to a pergola and a children's cabin using the same. Background Technology

[0002] Children's log cabins are a type of log cabin primarily used for children's entertainment. However, existing children's log cabins have simple structures and only provide basic climbing functions, which cannot meet the entertainment needs of different children.

[0003] Chinese Patent Application Publication No. CN119686569A discloses a children's wooden house, including a main body and a door ladder device. The main body has an entrance / exit on its front side. The door ladder device includes a rotating frame rotatably connected to the top of the main body, multiple horizontal ladders arranged parallel to the rotating frame, a sliding component slidably arranged on the rotating frame, a stepping mechanism arranged on the sliding component, a locking mechanism for switching the operation or stopping of the stepping mechanism, and a resistance adjustment mechanism for regulating the resistance of the stepping mechanism. The stepping mechanism includes two sets of transmission mechanisms symmetrically distributed about the sliding component along the width direction, and multiple pedals arranged parallel between the two sets of transmission mechanisms. The transmission mechanism includes a chain and two sets of transmission components arranged side by side along the length direction of the sliding component. This invention allows the door ladder device to be used as a door when blocked at the entrance / exit. The door ladder device can be used as a climbing structure in both vertical and tilted extended states, and is suitable for children of different weights to perform dynamic climbing exercises.

[0004] In the aforementioned cases involving dynamic climbing structures (such as dynamic staircases), the steps often sag rapidly when children step on them due to a lack of effective cushioning resistance. This can easily cause children to lose balance and fall due to sudden changes in their center of gravity, posing a safety hazard. Furthermore, these structures generally lack rapid braking protection mechanisms to address potential tipping or falls during play, rendering them unsuitable for use.

[0005] Therefore, a pergola and a children's wooden house using it are proposed. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a pergola and a children's wooden house using it, which can provide a dynamic staircase with high safety and stability.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A children's wooden house includes a base, a wooden house on the upper part of the base, a swing on the left side of the wooden house, a fence fixedly connected to the outside of the wooden house, a slide fixedly connected to the rear end of the wooden house, and a dynamic step ladder assembly at the front end of the wooden house.

[0009] The dynamic staircase assembly includes a support frame fixedly connected to the front end of the wooden house. Sprockets are rotatably connected to both the front and rear positions inside the support frame. Chains are engaged with the outer sides of the sprockets. Steps are fixedly connected to opposite sides of the chains on both sides. A rotating rod is fixedly connected to the lower two sprockets.

[0010] Preferably, a toothed rod is fixedly connected to both sides of the rotating rod, and a vertical block is fixedly connected to the upper end of the cylinder on the right side. A second threaded rod is threadedly connected to the inside of the vertical block. A first locking block matching the toothed rod is fixedly connected to the lower end of the second threaded rod. A first limiting rod is fixedly connected to both sides of the upper end of the first locking block. The first limiting rod is slidably connected to the inside of the vertical block.

[0011] Preferably, baffles are fixedly connected to both sides of the upper end of the support frame, and movable plates are slidably connected inside the baffles. Movable rods are fixedly connected to the front and rear positions of the opposite sides of the two movable plates. The movable rods are slidably connected to the inside of the baffles. A first spring is sleeved on the rod wall of the movable rod. Air pipes are fixedly connected to the opposite sides of the two baffles. An air cylinder is fixedly connected to the rear end of the cylinder. The upper end of the air cylinder is fixedly connected to the lower end of the air pipe. A piston block is slidably connected inside the air cylinder. A support rod is fixedly connected to the front end of the piston block. A second locking block is fixedly connected to the front end of the support rod. A second limiting rod is fixedly connected to the rear end of the second locking block. The second limiting rod is slidably connected to the rear end of the cylinder.

[0012] Preferably, a circular block is fixedly connected to each of the two baffles on opposite sides. The interior of the circular block is slidably connected to a moving rod. An arc-shaped block is fixedly connected to the wall of the moving rod. A protrusion is slidably connected to the upper and lower positions of the interior of the circular block. A second spring is fixedly connected to one side of the protrusion.

[0013] Preferably, a third spring is fixedly connected to the front end of the piston block, and a helical rod is fixedly connected to the rear end of the piston block. A one-way bearing is helically driven on the wall of the helical rod. The outer ring of the one-way bearing is rotatably connected to the air cylinder. A polygonal block is fixedly connected to the outer side of the one-way bearing. A sliding rod is slidably connected to both the upper and lower positions of the rear end of the air cylinder. A limit block is fixedly connected to the rear end of the sliding rod. The inner wall of the limit block matches the polygonal block, and the two are slidably configured. A fourth spring is sleeved on the wall of the sliding rod.

[0014] Preferably, a U-shaped tie rod is fixedly connected to the rear end of the limiting block.

[0015] Preferably, a turntable is rotatably connected to the upper end of the base, and a support cylinder is fixedly connected to the upper end of the turntable and the lower end of the wooden house. A round rod is slidably connected to the upper end of the support cylinder, and a toothed block is fixedly connected to the lower end of the round rod. The toothed block is embedded in the upper end of the base. The turntable and the support cylinder have toothed grooves that match the toothed block. A fifth spring is fixedly connected to the upper end of the toothed block.

[0016] A pergola adapted for children's wooden houses includes a pergola located on the right side of the wooden house, a seat inside the pergola, a sliding seat at the lower end of the pergola, a groove at the center of the sliding seat, a slider fixedly connected to the lower end of the base, the slider being located inside the groove, a limiting plate at the upper end of the sliding seat, and rotating balls evenly distributed at the lower end of the base.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) By setting up a dynamic step ladder consisting of sprockets, chains, and pedals, and innovatively integrating an adjustable resistance perforated plate structure inside the rotating rod, the downward speed of the pedals is buffered by controllable hydraulic oil resistance when children step on them. This effectively prevents the risk of children losing balance and falling due to the rapid descent of the pedals. At the same time, by rotating the first threaded rod, the position of the adjustable moving block can be changed, altering the relative distance between the first and second perforated plates, thereby adapting to the play needs of children of different weights and significantly improving the universality and safety of the equipment.

[0019] (2) When a child falls and hits the side panels while playing on the dynamic step ladder, the impact force triggers a pneumatic linkage braking mechanism. The compressed gas moving the step ladder pushes the piston block in the air cylinder through the air pipe, causing the second locking block to move forward quickly and engage with the gear on the rotating rod, instantly locking the rotating rod and sprocket, preventing the step ladder from moving further, thus avoiding the escalation of the dangerous situation. This function is passively triggered and requires no manual intervention, further improving safety.

[0020] (3) The braking mechanism incorporates a self-locking and reset module consisting of a helical rod, a one-way bearing, and a polygonal block. When the second locking block engages with the rack, the helical rod and piston block cannot move in the reverse direction under the action of the one-way bearing, ensuring the stability of the braking state and preventing accidental unlocking before the danger has passed. After the child has safely left, the adult can easily unlock the mechanism by pulling the U-shaped lever, allowing it to smoothly reset under the action of the spring. This design ensures the effectiveness of emergency braking and the safety of the reset operation.

[0021] (4) The main body of the wooden house can rotate relative to the base through structures such as turntables, toothed blocks, and springs, which makes it easy to adjust the orientation of the wooden house according to environmental factors such as sunlight and wind direction, improves the comfort of use, and helps the wooden house to dry and maintain evenly. At the same time, the pergola and the base of the wooden house are connected by structures such as sliders, grooves, and rotating balls, which allows the wooden house to be easily pushed under the pergola, effectively providing shade and rain protection, extending the service life of the wooden house, and providing additional rest space (seats under the pergola), greatly enhancing the practicality and functionality of the entire product under different weather conditions.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see Figure 1-12 A children's wooden house includes a base 5, a wooden house 8 at the top of the base 5, a swing 12 on the left side of the wooden house 8, a fence 13 fixedly connected to the outside of the wooden house 8, the fence 13 is used to provide some protection for children when playing in the wooden house 8, a slide 11 fixedly connected to the rear end of the wooden house 8, and a dynamic step ladder component at the front end of the wooden house 8.

[0039] The dynamic staircase assembly includes a support frame 19 fixedly connected to the front end of the wooden house 8. The support frame 19 provides support. Sprockets 30 are rotatably connected to both the front and rear positions inside the support frame 19. Chains 29 are engaged with the outer sides of the sprockets 30. Steps 32 are fixedly connected to opposite sides of the chains 29 on both sides, and the steps 32 can move with the chains 29. A rotating rod 31 is fixedly connected to the two lower sprockets 30. When the sprockets 30 rotate, they drive the rotating rod 31 to rotate. Cylinders 21 are fixedly connected to both sides of the support frame 19. Cylinders 21 have cavities 38 inside, filled with hydraulic oil. The rotating rods 31... A rectangular groove 40 is provided inside the rod wall. A movable block 41 is slidably connected inside the rectangular groove 40. The movable block 41 can move left and right inside the rectangular groove 40. A first hole plate 43 is fixedly connected to the upper and lower positions of the movable block 41. A second hole plate 42 is fixedly connected to the upper and lower positions of the rod wall of the rotating rod 31. The rotation of the rotating rod 31 drives the second hole plate 42 to rotate, and also drives the movable block 41 to rotate. The movable block 41 drives the first hole plate 43 to rotate. A first threaded rod 39 is rotatably connected inside the rectangular groove 40. By rotating the first threaded rod 39, the movable block 41 can move left and right inside the rectangular groove 40. The rod wall of the first threaded rod 39 is threadedly connected to the inside of the movable block 41.

[0040] When a child plays on pedal 32, stepping up on pedal 32 causes it to move downwards under gravity. Pedal 32 moves chain 29, which in turn rotates sprocket 30. The rotation of sprocket 30 then rotates rod 31, causing the fixedly connected second perforated plate 42 to move. As the second perforated plate 42 moves, the hydraulic oil inside the cavity 38 of cylinder 21 needs to pass through the hole, creating resistance. This results in slow movement of the second perforated plate 42, preventing rapid rotation of rod 31 and thus limiting the movement of pedal 32. The downward movement is relatively slow. As the child grows, their weight will increase accordingly. At this time, by rotating the first threaded rod 39, the moving block 41 moves inside the rectangular groove 40. The movement of the rectangular groove 40 drives the first hole plate 43 to move to the right, thereby increasing the resistance encountered by the rotating rod 31 when rotating. This makes it suitable for children of different weights. Compared with the existing technology, which does not have a component set when the dynamic step ladder is in use, the step 32 will move down quickly when the child steps on it, which can easily cause the child to lose balance and fall. By setting a certain resistance, the movement of the step 32 is hindered, giving the child enough time to adjust their balance. The body feel is relatively better, the safety is high, and the applicability is strong.

[0041] like Figure 8 and Figure 9As shown, a gear 34 is fixedly connected to both sides of the rotating rod 31. The rotating rod 31 and the gear 34 rotate synchronously. A vertical block 36 is fixedly connected to the upper end of the right cylinder 21. A second threaded rod 35 is threadedly connected to the inside of the vertical block 36. Rotating the second threaded rod 35 causes the second threaded rod 35 to move up and down relative to the vertical block 36. A first locking block 37 that matches the gear 34 is fixedly connected to the lower end of the second threaded rod 35. A first limiting rod 44 is fixedly connected to both sides of the upper end of the first locking block 37. The first limiting rod 44 is slidably connected to the inside of the vertical block 36. The first limiting rod 44 enables the first locking block 37 to move up and down stably.

[0042] When the child does not need the pedal 32 to move, the second threaded rod 35 is rotated, which drives the first locking block 37 to move downward. The first locking block 37 moves downward and engages with the upper end of the gear 34, thereby restricting the rotation of the gear 34. This prevents the rotating rod 31 from rotating and the sprocket 30 from rotating, thus preventing the pedal 32 from moving.

[0043] like Figure 8-12 As shown, baffles 20 are fixedly connected to both sides of the upper end of the support frame 19. The baffles 20 are used to allow children to hold onto the baffles 20 while walking on the footboard 32, and also provide a certain degree of limit protection. A movable plate 23 is slidably connected inside the baffle 20. The movable plate 23 is provided with a sealing ring on its outer side and can move left and right inside the baffle 20. Movable rods 22 are fixedly connected to the front and back positions of the two movable plates 23 on opposite sides. The movable rods 22 enable the movable plates 23 to move parallel to the baffles 20, thereby ensuring a sealing effect. The movable rods 22 are slidably connected to the inside of the baffles 20. A first spring 28 is sleeved on the rod wall of the movable rod 22. The first spring 28 enables the movable plates 23 to move parallel to each other after movement. The two baffles 20 are fixedly connected to each other on opposite sides by air pipes 33, which are used to transmit gas. The rear end of the cylinder 21 is fixedly connected to an air cylinder 45. The upper end of the air cylinder 45 is fixedly connected to the lower end of the air pipe 33. A piston block 49 is slidably connected inside the air cylinder 45. The piston block 49 can move left and right inside the air cylinder 45. A support rod 47 is fixedly connected to the front end of the piston block 49. The movement of the piston block 49 drives the support rod 47 to move. A second locking block 46 is fixedly connected to the front end of the support rod 47. The movement of the support rod 47 drives the second locking block 46 to move. A second limiting rod is fixedly connected to the rear end of the second locking block 46. The second limiting rod allows the second locking block 46 to mesh with the toothed rod 34 after it moves. The second limiting rod is slidably connected to the rear end of the cylinder 21.

[0044] When a child plays on the pedal 32, in the event of an accident, their body will tip over, creating a moving impact force on the movable plate 23. This causes the movable plate 23 to move rapidly. As the movable plate 23 moves, the gas inside the baffle 20 enters the air cylinder 45 through the air pipe 33. The increased air pressure inside the air cylinder 45 causes the piston block 49 to move forward. The forward movement of the piston block 49 moves the support rod 47, which in turn moves the second locking block 46. The second locking block 46 engages with the gear 34. Thus, when a child tip over while playing, the movement of the movable plate 23 increases the air pressure inside the air cylinder 45, pushing the piston block 49 to engage the second locking block 46 with the gear 34. This effectively limits the rotation of the sprocket 30, preventing further escalation of the danger. Additionally, when a child impacts the movable plate 23, the gas inside the baffle 20 provides a cushioning effect, improving the safety performance of the device.

[0045] like Figure 7 As shown, a circular block 24 is fixedly connected to the opposite side of each of the two baffles 20. The inside of the circular block 24 is slidably connected to the moving rod 22. An arc-shaped block 25 is fixedly connected to the rod wall of the moving rod 22. When the moving rod 22 moves, it drives the arc-shaped block 25 to move. A protrusion 27 is slidably connected to the upper and lower positions inside the circular block 24. A second spring 26 is fixedly connected to one side of the protrusion 27. The second spring 26 provides a certain supporting force to the protrusion 27.

[0046] When the movable plate 23 is impacted, it causes the movable rod 22 to move. The movable rod 22 then causes the arc block 25 to move. When the arc block 25 moves, it needs to push the protrusion 27 to move in order to move laterally. Therefore, when a child is playing normally, the force with which he holds the movable plate 23 will not cause the movable plate 23 to move, and thus will not cause the second locking block 46 to move. Only a sufficient impact force can cause the second locking block 46 to move, which further improves the applicability of the device.

[0047] like Figure 11 and Figure 12As shown, a third spring 48 is fixedly connected to the front end of the piston block 49. The third spring 48 is used to reset the piston block 49. The elastic force of the third spring 48 will not affect the movement of the piston block 49 under the thrust of the gas, and the elastic coefficient is small. A helical rod 51 is fixedly connected to the rear end of the piston block 49. A one-way bearing 52 is helically driven on the rod wall of the helical rod 51. The one-way bearing 52 is divided into an inner ring and an outer ring. In one direction, the inner ring and the outer ring rotate relative to each other, and in the other direction, the inner ring and the outer ring are locked relative to each other. The outer side of the outer ring of the one-way bearing 52 is rotatably connected to the air cylinder 45. A polygonal block 50 is fixedly connected to the outer side of the one-way bearing 52. A slide rod 54 is slidably connected to the upper and lower positions of the rear end of the air cylinder 45. A limit block 55 is fixedly connected to the rear end of the slide rod 54. The inner wall of the limit block 55 matches the polygonal block 50, and the two are slidably set. A fourth spring 53 is sleeved on the rod wall of the slide rod 54. When the limit block 55 moves, it drives the slide rod 54 to move. The fourth spring 53 is used to reset the slide rod 54. A U-shaped pull rod is fixedly connected to the rear end of the limit block 55. The U-shaped pull rod makes it easy to pull the limit block 55.

[0048] When piston block 49 moves, it drives the fixedly connected screw rod 51 at the rear end to move. When screw rod 51 moves forward, the inner and outer rings of one-way bearing 52 rotate relative to each other, thus preventing screw rod 51 from moving forward without resistance. When the second locking block 46 engages with the gear 34, and the moving plate 23 resets, because the person is still on the upper end of pedal 32, the gear 34 tends to rotate, pushing the second locking block 46 to move backward. Screw rod 51 wants to move backward, but the one-way bearing 52 is locked, preventing screw rod 51 from moving backward. This ensures the engagement between the second locking block 46 and the gear 34, preventing sprocket 30 from rotating. When the child leaves pedal 32, this... When the U-shaped pull rod moves the limiting block 55 backward, the polygonal block 50 is no longer restricted. At this time, the piston block 49 moves backward under the action of the third spring 48, and the spiral rod 51 moves, causing the one-way bearing 52 to rotate as a whole. After the piston block 49 returns to its original position, the U-shaped pull rod is released, and under the action of the fourth spring 53, the limiting block 55 returns to its original position, restricting the polygonal block 50 and preventing the outer ring of the one-way bearing 52 from rotating. In this way, in the event of danger, after the second locking block 46 engages with the rack 34, the one-way bearing 52 and the spiral rod 51 ensure that the second locking block 46 will not disengage from the rack 34, guaranteeing a stable engagement effect and preventing the pedal 32 from moving, further improving the safety of the component.

[0049] like Figure 3 and Figure 4As shown, a turntable 6 is rotatably connected to the upper end of the base 5. The turntable 6 can rotate relative to the base 5. A support cylinder 14 is fixedly connected to the upper end of the turntable 6 and the lower end of the wooden house 8. A round rod 15 is slidably connected to the upper end of the support cylinder 14. A toothed block 17 is fixedly connected to the lower end of the round rod 15. Part of the toothed block 17 is located at the upper end of the base 5, and part is located at the lower end of the turntable 6. The toothed block 17 is embedded in the upper end of the base 5. The turntable 6 and the support cylinder 14 are provided with toothed grooves 18 that match the toothed block 17. A fifth spring 16 is fixedly connected to the upper end of the toothed block 17. The fifth spring 16 exerts a downward pushing force on the toothed block 17.

[0050] By pulling up the round rod 15, the round rod 15 moves upward, causing the toothed block 17 to move upward. The toothed block 17 moves upward and disengages from the upper end of the base 5. At this time, the turntable 6 can be rotated, which in turn allows the wooden house 8 to rotate. After rotating to the correct angle, the round rod 15 is released, and under the action of the fifth spring 16, the toothed block 17 moves downward and re-engages with the upper end of the base 5, thus preventing the turntable 6 from rotating relative to the base 5. In this way, when using the wooden house 8, the direction of the wooden house 8 can be adjusted as needed. For example, when there is wind or strong sunlight, the appropriate angle can be adjusted to reduce the impact on use. At the same time, after the rainy season, by rotating, the wooden house 8 can be exposed to sunlight from all angles, improving the applicability of the device.

[0051] Example 2:

[0052] Please see Figure 1 and Figure 2 A pergola includes a pergola 2 located on the right side of a wooden house 8. The pergola 2 has a seat 3 inside and a sliding seat 1 at its lower end. A groove 4 is formed at the center of the sliding seat 1. A slider 10 is fixedly connected to the lower end of a base 5, allowing the slider 10 to move within the groove 4. The upper end of the sliding seat 1 has a limiting plate 7, which is detachable and can limit the edge of the wooden house 8 during use, ensuring its stability. Rotating balls 9 are evenly distributed at the lower end of the base 5, allowing the base 5 to move more smoothly. This allows the wooden house 8 to be moved into the pergola 2 after rain or when the sun is strong, thus preventing damage to the wooden house 8.

[0053] Working principle: When a child plays on pedal 32, stepping up on pedal 32 causes it to move downwards under gravity. Pedal 32 drives chain 29, which in turn rotates sprocket 30. The rotation of sprocket 30 then rotates rod 31, causing the fixedly connected second perforated plate 42 to move. As the second perforated plate 42 moves, the hydraulic oil inside the cavity 38 of cylinder 21 needs to pass through the hole, creating resistance. This results in slow movement of the second perforated plate 42, preventing rapid rotation of rod 31 and thus allowing the pedal to move more smoothly. When step 32 moves downwards, it moves relatively slowly. As children grow, their weight increases accordingly. At this time, by rotating the first threaded rod 39, the moving block 41 moves inside the rectangular groove 40. The movement of the rectangular groove 40 drives the first hole plate 43 to move to the right, thereby increasing the resistance encountered by the rotating rod 31 when rotating. This makes it suitable for children of different weights. Compared with the existing technology, which does not have a component set when the dynamic step ladder is in use, the step 32 will move downwards quickly when the child steps on it, which can easily cause the child to lose balance and fall. By setting a certain resistance, the movement of the step 32 is hindered, giving the child enough time to adjust their balance. The body feel is relatively better, the safety is high, and the applicability is strong.

[0054] Furthermore, when a child is playing on the pedal 32, in the event of an accident, their body will tip over, creating a moving impact force on the movable plate 23, causing it to move rapidly. As the movable plate 23 moves, the gas inside the baffle 20 enters the air cylinder 45 through the air pipe 33, increasing the air pressure inside the air cylinder 45. This causes the piston block 49 to move forward, which in turn moves the support rod 47. The support rod 47 then moves the second locking block 46, engaging it with the gear rod 34. Thus, when a child is playing and tip over, the movement of the movable plate 23 increases the air pressure inside the air cylinder 45, pushing the piston block 49 to engage the second locking block 46 with the gear rod 34, thereby preventing the child from falling. The timely restriction of the sprocket 30's rotation prevents further escalation of the danger. Simultaneously, when a child impacts the moving plate 23, the gas inside the baffle 20 provides a buffering effect, improving the device's safety performance. When the moving plate 23 is impacted, it drives the moving rod 22, which in turn moves the arc-shaped block 25. The arc-shaped block 25 needs to push the protrusion 27 to move laterally. Therefore, when a child is playing normally, the force with which they hold the moving plate 23 will not cause it to move, thus preventing the second locking block 46 from moving. Only sufficient impact force can move the second locking block 46, further enhancing the device's applicability. (Piston) When block 49 moves, it drives the fixedly connected screw rod 51 at the rear end to move. When the screw rod 51 moves forward, the inner and outer rings of the one-way bearing 52 rotate relative to each other, thus preventing the screw rod 51 from moving forward without resistance. When the second locking block 46 engages with the gear 34, and the moving plate 23 resets, because the person is still on the upper end of the pedal 32, the gear 34 tends to rotate, pushing the second locking block 46 to move backward. The screw rod 51 wants to move backward, but the one-way bearing 52 is locked, preventing the screw rod 51 from moving backward. This ensures the engagement between the second locking block 46 and the gear 34, preventing the sprocket 30 from rotating. When the child leaves the pedal 32, at this time... The U-shaped pull rod causes the limiting block 55 to move backward, which removes the restriction on the polygonal block 50. At this time, the piston block 49 moves backward under the action of the third spring 48, and the movement of the helical rod 51 causes the one-way bearing 52 to rotate as a whole. After the piston block 49 returns to its original position, the U-shaped pull rod is released, and under the action of the fourth spring 53, the limiting block 55 returns to its original position, restricting the polygonal block 50 and preventing the outer ring of the one-way bearing 52 from rotating. In this way, in the event of danger, after the second locking block 46 engages with the gear 34, the one-way bearing 52 and the helical rod 51 ensure that the second locking block 46 will not disengage from the gear 34, thus ensuring a stable engagement effect and preventing the pedal 32 from moving, further improving the safety of the component.

[0055] Furthermore, by pulling up the round rod 15, the round rod 15 moves upward, causing the toothed block 17 to move upward. The toothed block 17 moves upward and disengages from the upper end of the base 5. At this time, the turntable 6 can be rotated, which in turn allows the wooden house 8 to rotate. After rotating to the correct angle, the round rod 15 is released, and under the action of the fifth spring 16, the toothed block 17 moves downward and re-engages into the upper end of the base 5, thus preventing the turntable 6 from rotating relative to the base 5. In this way, when using the wooden house 8, the direction of the wooden house 8 can be adjusted as needed. For example, when there is wind or strong sunlight, the appropriate angle can be adjusted to reduce the impact on use. At the same time, after the rainy season, by rotating, the wooden house 8 can be exposed to sunlight from all angles, improving the applicability of the device.
