Description

Technical Field

[0001] The utility model belongs to the technical field of sunshade devices, and in particular relates to a rainproof and sunshade device for garden landscapes. Background Art

[0002] Garden landscape refers to the environment created in a certain area by using engineering technology and artistic means, through transforming the terrain, planting trees, flowers and plants, constructing buildings and arranging garden paths. In order to create a suitable environment for tourists to rest, it is necessary to install rain and sun protection devices in the garden landscape.

[0003] The Chinese patent with announcement number CN221306658U discloses a retractable sunshade for landscaping. The scheme includes a base and a column. A U-shaped fixing frame is fixed on the top of the column. A screw rod is rotatably provided on one side of the U-shaped fixing frame. A slider is provided on the outer sleeve of the screw rod. One side of the slider is rotatably connected to the first telescopic rod. The middle part of the two first telescopic rods is rotatably connected, and one end of the two first telescopic rods is rotatably connected to the second telescopic rod. One end of the two second telescopic rods is rotatably connected to the second connecting block. A square bar is fixedly connected to one side of the second connecting block. The above scheme uses a sliding slider to extend the first telescopic rod and the second telescopic rod to drive the square bar to move and extend the sunshade cloth, thereby achieving the effect of blocking the sun for tourists.

[0004] When the above solution is in use, the square bar is rotatably connected to the two second connecting rods through the second connecting block fixed on one side thereof, which causes the square bar to easily rotate relative to the U-shaped fixing frame, thereby causing the above solution to be easily twisted and deformed when subjected to rain erosion, and has poor stability during use. Utility Model Content

[0005] The utility model aims to provide a rain and sun shading device for garden landscape, so as to solve the problem of poor stability during use of the above-mentioned solution.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A rain and sunshade device for garden landscapes, including a base. A column is fixedly arranged on the top of the base. An I-shaped mounting frame is fixedly arranged on the top of the column. An extension mechanism is arranged on the left side of the mounting frame. A roller is rotatably arranged on the right side of the mounting frame in the front-rear direction. A sunshade cloth is wound around the roller. One end of the sunshade cloth is fixedly connected to the side wall of the roller. The extension mechanism includes a bidirectional screw, sliders and a square bar. The front and rear ends of the bidirectional screw are respectively rotatably inserted into the mounting frame. There are two sliders, which are symmetrically sleeved on the positive and negative threaded sections of the bidirectional screw. The two sliders are in sliding contact with the side wall of the mounting frame. The left sides of the sliders are respectively rotatably connected with a first connecting rod. The left ends of the two first connecting rods are respectively rotatably connected with the front and rear ends of the right side of the square bar. The front and rear ends of the left side of the mounting frame are respectively rotatably connected with a second connecting rod. The left end of the second connecting rod is rotatably connected with the middle of the adjacent first connecting rod. The other end of the sunshade cloth is fixedly connected to the square bar.

[0008] The principle and effect of this technical solution:

[0009] In the initial state, the two sliders are close to each other, and the square bar is close to the mounting frame. When it is necessary to unfold the sunshade cloth, rotate the bidirectional screw. Due to the mounting frame restricting the rotation of the sliders, the two sliders move away from each other as the bidirectional screw rotates and are respectively close to the front and rear sides of the mounting frame. When the sliders move, they push the first connecting rod to rotate, making the left end of the first connecting rod move away from the mounting frame, and then pushing the square bar and the other end of the sunshade cloth away from the mounting frame, thereby stretching the sunshade cloth wound around the roller.

[0010] Through the above settings, the front and rear ends of the square bar are respectively rotatably connected with the first connecting rod, and by rotating the bidirectional screw, the two first connecting rods are simultaneously driven to rotate to push the square bar away from the mounting frame, which can prevent the square bar from rotating relative to the mounting frame and improve the stability of the present invention during use.

[0011] In the present invention, sleeves are fixedly arranged on the front and rear sides of the mounting frame along the axial direction of the roller. The two ends of the roller extend into the sleeves. A coil spring is sleeved outside the roller. The two ends of the coil spring are respectively connected to the roller and the inner wall of the sleeve.

[0012] The principle and effect of this technical solution:

[0013] When rotating the bidirectional screw to drive the square bar to move away from the mounting frame, the roller rotates accordingly, causing the coil spring to deform and have elastic force. When rotating the bidirectional screw in the reverse direction to drive the square bar to move closer to the mounting frame, the coil spring drives the roller to rotate in the reverse direction, thereby tightening the sunshade cloth.

[0014] Through the above settings, it is possible to tighten the sunshade cloth by the roller during the process of moving the square bar closer to the mounting frame, preventing the sunshade cloth from sagging due to gravity and thus avoiding adverse effects on tourists.

[0015] The present invention also includes a support mechanism, which is provided with two groups and is located on the front and rear sides of the square bar. Each group of support mechanisms includes a sliding rod and a rod sleeve. The bottom of the sliding rod is slidably inserted into the top of the rod sleeve, the top of the sliding rod is rotatably connected to the end of the square bar, and the bottom of the rod sleeve is rotatably connected to the column. A ratchet bar is provided on the side wall of the sliding rod, and a sliding groove is provided in the rod sleeve on the side close to the ratchet bar. A limit block is slidably embedded in the sliding groove, and a compression spring is provided between the limit block and the end wall of the sliding groove. A guide push inclined surface cooperating with the ratchet bar is provided at one end of the limit block close to the ratchet bar.

[0016] In the present invention, a lever is slidably provided on the end wall of the slide groove, one end of the lever extends into the slide groove and is rotatably connected to the limit block, a compression spring is sleeved on the lever, a turning handle is fixedly provided on the side wall of the other end of the lever, and a protrusion is fixedly provided on the outer side of the end wall of the slide groove.

[0017] The principle and effect of this technical solution:

[0018] When the square bar moves in the direction away from the mounting frame, it drives the slide rod away from the rod sleeve, the ratchet bar contacts the guide push slope of the limit block, and pushes the limit block to move into the slide groove. When the square bar moves to the predetermined position and encounters a rainy environment, the rain will impact the curtain cloth and remain on the surface of the curtain cloth. The square bar tends to move downward. At this time, the limit block contacts the straight section of the ratchet bar, thereby preventing the slide rod from sliding downward, thereby providing support for the square bar. When it is necessary to drive the square bar to move in the direction close to the mounting frame, pull up and turn the lever to move the limit block into the slide groove, and make the turning handle close to one end of the limit block and abut against the protrusion, so that the limit block cannot be reset under the action of the compression spring. At this time, rotate the two-way screw in the opposite direction to reset the square bar and the slide rod.

[0019] Through the above arrangement, support can be provided for the square bars, preventing the square bars from moving downward and bending the first connecting rod and the second connecting rod when impacted by rainwater and bearing the gravity of rainwater, thereby improving the stability of the utility model during use and extending the service life of the utility model.

[0020] In the present invention, a servo motor connected to a bidirectional screw is fixedly provided on the side wall of the mounting frame. Through the above arrangement, the bidirectional screw can be driven to rotate in two directions, thereby achieving the purpose of extending and contracting the square bar.

[0021] In the present invention, a crossbar is fixedly mounted above the mounting frame in the front-to-back direction, and the curtain is passed through the gap between the crossbar and the mounting frame. This arrangement allows debris adhering to the curtain surface to be removed while the rollers are tightening the curtain, preventing debris from rotting and contaminating the curtain.

[0022] In the present utility model, through holes for passing fixing bolts are provided at the four corners of the top of the base. Through the above arrangement, after the fixing bolts pass through the through holes, they are inserted into the ground, further strengthening the base and improving the stability of the present utility model during use.

A coil spring 122 is provided on the outer sleeve of the roller 30, and both ends of the coil spring 122 are respectively connected to the roller 30 and the inner wall of the sleeve 121.

[0033] In this embodiment, a support mechanism 50 is also included, which is provided with two groups of support mechanisms 50 and is located on the front and rear sides of the square bar 23. Each group of support mechanisms 50 includes a slide bar 51 and a rod sleeve 52. The bottom of the slide bar 51 is slidably inserted into the top of the rod sleeve 52. The top of the slide bar 51 is rotatably connected to the end of the square bar 23, and the bottom of the rod sleeve 52 is rotatably connected to the column 11. A ratchet bar 511 is provided on the side wall of the slide bar 51, and a slide groove 521 is provided in the rod sleeve 52 on the side close to the ratchet bar 511. A limit block 522 is slidably embedded in the slide groove 521, and a compression spring 523 is provided between the limit block 522 and the end wall of the slide groove 521. The limit block 522 is provided with a guide inclined surface that cooperates with the ratchet bar 511 at one end close to the ratchet bar 511.

[0034] In this embodiment, a lever 524 is slidably provided on the end wall of the slide groove 521.

A handle 525 is fixedly provided on the side wall of the other end of the lever 524. A protrusion 526 is fixedly provided on the outer side of the end wall of the slide groove 521.

[0035] In this embodiment, a servo motor 13 is fixedly mounted on the side wall of the mounting frame 12 and is in transmission connection with the bidirectional screw 21 .

[0036] In this embodiment, a cross bar 14 is fixedly arranged above the mounting frame 12 in the front-back direction, and the covering cloth 40 is threaded through the gap between the cross bar 14 and the mounting frame 12.

[0037] In this embodiment, through holes 15 for passing fixing bolts are formed at the four corners of the top of the base 10.

[0038] The specific implementation process is as follows:

[0039] In the initial state, the two sliders 22 are close to each other, and the square bar 23 is close to the mounting frame 12. When it is necessary to unfold the covering cloth 40, the bidirectional screw 21 is rotated. Due to the mounting frame 12 restricting the rotation of the sliders 22, the two sliders 22 move away from each other as the bidirectional screw 21 rotates and are respectively close to the front and rear sides of the mounting frame 12. When the sliders 22 move, the first link 221 is pushed to rotate, so that the left end of the first link 221 moves away from the mounting frame 12, and then the square bar 23 and the other end of the covering cloth 40 are pushed away from the mounting frame 12, and then the covering cloth 40 wound around the roller 30 is stretched.

[0040] When the bidirectional screw 21 is rotated to drive the square bar 23 to move away from the mounting frame 12, the roller 30 rotates accordingly, so that the coil spring 122 is deformed and has elastic force. When the bidirectional screw 21 is rotated in the reverse direction to drive the square bar 23 to move towards the mounting frame 12, the coil spring 122 drives the roller 30 to rotate in the reverse direction, thereby tightening the covering cloth 40.

[0041] When the square bar 23 moves away from the mounting frame 12, the sliding rod 51 is driven to move away from the rod sleeve 52, the ratchet rack 511 contacts the guiding and pushing inclined surface of the limiting block 522, and the limiting block 522 is pushed to move into the sliding groove 521. When the square bar 23 moves to a predetermined position and encounters a rainy environment, rainwater will impact the covering cloth 40 and remain on the surface of the covering cloth 40. The square bar 23 has a tendency to move downward. At this time, the limiting block 522 contacts the straight section of the ratchet rack 511, thereby preventing the sliding rod 51 from sliding downward, and thus providing support for the square bar 23. When it is necessary to drive the square bar 23 to move towards the mounting frame 12, the lever 524 is pulled up and rotated, so that the limiting block 522 moves into the sliding groove 521, and the end of the rotating handle 525 close to the limiting block 522 abuts against the convex block 526, so that the limiting block 522 cannot be reset under the action of the compression spring 523. At this time, the bidirectional screw 21 is rotated in the reverse direction to reset the square bar 23 and the sliding rod 51.

[0042] The above are only embodiments of the present utility model, and common general technical solutions or characteristics in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solutions of the present utility model, several modifications and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent. The protection scope claimed in this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
