Description

Technical Field

[0001] This utility model relates to the field of eaves rain protection technology, and in particular to a protective device for eaves rain protection. Background Technology

[0002] A canopy is a building fixture installed above the entrance or rooftop balcony of a building to protect against rain, wind, and falling objects. Old-style building canopies use reinforced concrete beam-slab or slab structures, which are bulky, large, and space-consuming, making it difficult to achieve high levels of transparency.

[0003] An existing patent (publication number: CN108952031A) discloses a retractable window awning rain shelter, including a side panel. A horizontal plate is located at the upper end of one side of the side panel, and a support base is located at the lower end of the horizontal plate. A connecting seat is located on one side of the support base. When a crank is used to rotate the screw, it drives a spiral tube to rotate, which in turn drives a gear to rotate, further driving a rotating shaft to rotate. Through the cooperation between the horizontal plate and connecting rods one, two, three, and four, it facilitates rain and sun protection for balconies or windowsills, forming an adjustable rain shelter. However, this technical solution still has shortcomings, specifically as follows:

[0004] The aforementioned device uses a crank to drive a spiral tube, which in turn rotates a gear to open the waterproof tarpaulin. However, it is difficult to fix the length of the tarpaulin opening, leading to swaying during heavy rain and strong winds, thus reducing the effectiveness of the rain shelter. Therefore, we propose a protective device for eaves rain protection to address these problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a protective device for eaves rain protection, which can solve the problem that the existing device uses a crank to drive a spiral tube to rotate the gear and open the waterproof cloth. However, the above device is difficult to fix the length of the waterproof cloth opening, which leads to swaying during stormy weather and thus poor rain protection effect.

[0007] To solve the above technical problems, this utility model provides a protective device for eaves rain protection, which adopts the following technical solution: it includes a connecting plate, two connecting blocks are fixedly connected to the bottom of the connecting plate, a roller is rotatably connected to the opposite side of the two connecting blocks, a rainproof cloth is fixedly sleeved on the side of the roller, and a C-shaped block is fixedly connected to the front side of each of the two connecting blocks.

[0008] A support rod is rotatably connected to the inner wall of the C-shaped block, the front end of the roller passes through the front side of the front connecting block and is fixedly sleeved with a worm gear, and an adjusting component is fixedly connected to the lower side of the connecting plate.

[0009] By adopting the above technical solution, this solution facilitates the fixing of the rain cover, making the rain cover more effective in strong winds and heavy rain. It also allows the rain cover to be fixed after being moved to a suitable length, so that the rain cover can be quickly adjusted to the appropriate length.

[0010] Optionally, the adjusting component includes an L-shaped plate, a rotating rod rotatably connected to the side of the horizontal plate of the L-shaped plate, and a worm gear fixedly connected to the top end of the rotating rod, the worm gear meshing with a worm wheel.

[0011] By adopting the above technical solution, this solution enables the worm gear to drive the roller to rotate through the rotation of the worm.

[0012] Optionally, the bottom end of the rotating rod is provided with a T-shaped groove, and a T-shaped rod is slidably connected inside the T-shaped groove. A compression spring is fixedly sleeved on the side of the vertical rod of the T-shaped rod. The bottom end of the compression spring is fixedly connected to the lower side of the inner wall of the vertical groove of the T-shaped groove, and the top end of the compression spring is fixedly connected to the lower side of the horizontal rod of the T-shaped rod.

[0013] By adopting the above technical solution, this solution can move the T-shaped rod downward to drive the L-shaped rod downward, so that the vertical rod of the L-shaped rod moves out of the slot, thereby releasing the fixation of the rotating rod.

[0014] Optionally, an L-shaped rod is fixedly connected to the side of the vertical rod of the T-shaped rod, and a number of slots are provided at the bottom of the horizontal plate of the L-shaped plate. The number of slots are equidistantly arranged in a ring on the lower side of the horizontal plate of the L-shaped plate, and the side of the vertical rod of the L-shaped rod is slidably connected to the inside of one of the slots.

[0015] By adopting the above technical solution, this solution moves the vertical bar of the L-shaped rod into the interior of different slots, and then moves the L-shaped hinge bar to different positions and fixes it.

[0016] Optionally, the support rod includes two L-shaped hinge bars, with the two right-side diagonal bars of the two L-shaped hinge bars rotatably connected to the inside of the C-shaped block, and the two left-side diagonal bars of the two L-shaped hinge bars rotatably connected to the lower side of the rain cover.

[0017] By adopting the above technical solution, this solution can deflect through the L-shaped hinge strip, thereby supporting the lower side of the telescopic or closed rain cover, reducing the possibility of excessive rainwater accumulation on the upper side of the rain cover causing it to tilt.

[0018] Optionally, the vertical cross-section of the side of the rotating rod is convex, and a silicone sheet is fixedly sleeved on the lower side of the side of the rotating rod.

[0019] By adopting the above technical solution, this solution uses a rotating rod with a convex vertical cross-section to make the convex part of the rotating rod swing when it rotates, which makes the rotation of the rotating rod more convenient.

[0020] Optionally, a bearing is fixedly sleeved on the side of the roller, and the outer ring of the bearing is fixedly connected to the interior of the front connecting block.

[0021] By adopting the above technical solution, this solution reduces the frictional force generated when the roller rotates on the side of the connecting block through the bearing.

[0022] Optionally, the rain cover is made of nylon fabric and has a thickness of 5mm.

[0023] By adopting the above technical solution, this solution provides nylon tarpaulin with strong waterproof performance, long service life, and good abrasion resistance.

[0024] In summary, this utility model has at least one of the following beneficial effects:

[0025] The L-shaped rod drives the T-shaped rod downwards, compressing the spring and causing the vertical rod of the L-shaped rod to move out of the slot. The rotating rod drives the worm gear to rotate, which in turn drives the worm wheel and roller to rotate, opening the rain cover. Releasing the L-shaped rod allows it and the T-shaped rod to return to their original positions via the spring. At this point, the vertical rod of the L-shaped rod moves back into the slot, thus securing the rain cover and improving its effectiveness in heavy rain and strong winds.

[0026] Move the L-shaped rod downwards to drive the T-shaped rod, releasing the fixing of the rotating rod. The rotating rod drives the worm gear to rotate, which in turn drives the worm wheel and roller to rotate. This causes the roller to unfold the rain cover and the two L-shaped hinge strips to unfold to the appropriate length. Once the rain cover has unfolded to the appropriate length, stop rotating the rotating rod. By releasing the L-shaped rod, the vertical bar of the L-shaped rod moves into the slot through the rebound force of the T-shaped rod and the compression spring. Fix the rain cover that has moved to the appropriate length, and the rain cover can be quickly adjusted to the appropriate length. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0034] Example 1, refer to Figure 1-4 In this embodiment, to address the problem that existing devices use a crank handle to rotate a spiral tube and open a gear to open the waterproof fabric, but these devices struggle to maintain a fixed length of opening, leading to swaying during heavy rain and strong winds, thus reducing the effectiveness of the rain shelter, this invention discloses a protective device for eaves rain protection.

[0035] The device includes a connecting plate 1, with two connecting blocks 2 fixedly connected to the bottom of the connecting plate 1. Rollers 3 are rotatably connected to the opposite side of the two connecting blocks 2. The front end of the rollers 3 passes through the front side of the front connecting block 2 and is fixedly sleeved with a worm gear 7. An adjusting component 8 is fixedly connected to the lower side of the connecting plate 1.

[0036] The adjusting component 8 includes an L-shaped plate 801. A rotating rod 802 is rotatably connected to the side of the horizontal plate of the L-shaped plate 801. A worm 803 is fixedly connected to the top of the rotating rod 802. The worm 803 meshes with the worm wheel 7. The rotation of the worm 803 can cause the worm wheel 7 to drive the roller to rotate.

[0037] The bottom end of the rotating rod 802 is provided with a T-shaped groove 804. A T-shaped rod 805 is slidably connected inside the T-shaped groove 804. A compression spring 806 is fixedly sleeved on the side of the vertical rod of the T-shaped rod 805. The bottom end of the compression spring 806 is fixedly connected to the lower side of the inner wall of the vertical groove of the T-shaped groove 804, and the top end of the compression spring 806 is fixedly connected to the lower side of the horizontal rod of the T-shaped rod 805. By moving the T-shaped rod 805 downward, the L-shaped rod 807 can be moved downward, so that the vertical rod of the L-shaped rod 807 moves out of the slot 808, thereby releasing the fixation of the rotating rod 802.

[0038] The side of the vertical rod of the T-shaped rod 805 is fixedly connected to the L-shaped rod 807. The bottom of the horizontal plate of the L-shaped plate 801 is provided with several slots 808. The slots 808 are equally spaced and arranged in a ring on the lower side of the horizontal plate of the L-shaped plate 801. The side of the vertical rod of the L-shaped rod 807 is slidably connected to the inside of one of the slots 808. By moving the vertical rod of the L-shaped rod 807 into the inside of different slots 808, the L-shaped hinge bar 601 is moved to different positions and fixed.

[0039] The specific working principle is as follows: First, the L-shaped rod 807 drives the T-shaped rod 805 to move downward, compressing the compression spring 806 and causing the vertical rod of the L-shaped rod 807 to move out of the slot 808. Then, the rotating rod 802 drives the worm gear 803 to rotate, which in turn drives the worm wheel 7 and the roller 3 to rotate, thus opening the rain cover 4. Next, the L-shaped rod 807 is released, allowing the L-shaped rod 807 and the T-shaped rod 805 to return to their original positions due to the rebound force of the compression spring 806. At this time, the vertical rod of the L-shaped rod 807 moves into the slot 808, which quickly fixes the open rain cover 4, making the rain cover 4 more effective in heavy rain and strong winds.

[0040] Example 2, refer to Figure 1-4 In this embodiment, in order to solve the problem of difficulty in adjusting the rain shelter to a suitable length, based on the same concept as in Embodiment 1 above, the protective device for eaves rain shelter further includes:

[0041] The connecting plate 1 has two connecting blocks 2 fixedly connected to its bottom. C-shaped blocks 5 are fixedly connected to the front side of each of the two connecting blocks 2. Support rods 6 are rotatably connected to the inner side of the C-shaped blocks 5. The front end of the roller 3 passes through the front side of the front connecting block 2 and is fixedly sleeved with a worm gear 7. An adjusting component 8 is fixedly connected to the lower side of the connecting plate 1.

[0042] The side of the vertical rod of the T-shaped rod 805 is fixedly connected to the L-shaped rod 807. The bottom of the horizontal plate of the L-shaped plate 801 is provided with several slots 808. The slots 808 are equally spaced and arranged in a ring on the lower side of the horizontal plate of the L-shaped plate 801. The side of the vertical rod of the L-shaped rod 807 is slidably connected to the inside of one of the slots 808. By moving the vertical rod of the L-shaped rod 807 into the inside of different slots 808, the L-shaped hinge bar 601 is moved to different positions and fixed.

[0043] The support rod 6 includes two L-shaped hinge bars 601. The two right-side diagonal bars of the two L-shaped hinge bars 601 are rotatably connected to the inside of the C-shaped block 5, and the two left-side diagonal bars of the two L-shaped hinge bars 601 are rotatably connected to the lower side of the rain cover 4. The L-shaped hinge bars 601 can deflect, thereby supporting the lower side of the rain cover 4 when it is extended or closed, reducing the possibility of excessive rainwater accumulation on the upper side of the rain cover causing it to tilt.

[0044] The side vertical cross-section of the rotating rod 802 is convex, and a silicone sheet is fixedly sleeved on the lower side of the rotating rod 802. The convex shape of the rotating rod 802 makes the convex part swing when rotating, which makes the rotation of the rotating rod 802 more convenient.

[0045] The specific working principle is as follows: After the L-shaped rod 807 drives the T-shaped rod 805 downward, the fixing of the rotating rod 802 is released. Then, the rotating rod 802 drives the worm gear 803 to rotate. When the worm gear 803 rotates, it drives the worm wheel 7 and the roller 3 to rotate, so that the roller 3 drives the rain cover 4 on its side to unfold to the left, and the two L-shaped hinge bars 601 unfold to the appropriate length. When the rain cover 4 unfolds to the appropriate length, the rotating rod 802 stops rotating. Then, by releasing the L-shaped rod 807, the vertical bar of the L-shaped rod 807 moves upward into the slot 808 through the rebound force of the T-shaped rod 805 and the compression spring 806. The rain cover that has moved to the appropriate length is fixed, so that the rain cover can be quickly adjusted to the appropriate length.

[0046] Example 3, referring to Figure 1-4 In this embodiment, to address the problem that existing rain shelters are loose after being stored, leading to them easily coming undone, based on the same concept as in Embodiment 1, this protective device for eaves rain protection further includes:

[0047] Connecting plate 1, with two connecting blocks 2 fixedly connected to the bottom of connecting plate 1, and an adjusting component 8 fixedly connected to the lower side of connecting plate 1.

[0048] The side of the vertical rod of the T-shaped rod 805 is fixedly connected to the L-shaped rod 807. The bottom of the horizontal plate of the L-shaped plate 801 is provided with several slots 808. The slots 808 are equally spaced and arranged in a ring on the lower side of the horizontal plate of the L-shaped plate 801. The side of the vertical rod of the L-shaped rod 807 is slidably connected to the inside of one of the slots 808. By moving the vertical rod of the L-shaped rod 807 into the inside of different slots 808, the L-shaped hinge bar 601 is moved to different positions and fixed.

[0049] A bearing is fixedly sleeved on the side of the roller 3. The outer ring of the bearing is fixedly connected to the inside of the front connecting block 2. The bearing reduces the friction force generated when the roller 3 rotates on the side of the connecting block 2.

[0050] The rain cover 4 is made of nylon fabric and has a thickness of 5mm. Nylon fabric has strong waterproof performance, a long service life, and good wear resistance.

[0051] The specific working principle is as follows: After the L-shaped rod 807 moves out of the slot 808, the rotating rod 802 is rotated counterclockwise, causing the rotating rod 802 to drive the worm gear 803 to rotate counterclockwise. The worm gear 803 drives the worm wheel 7 and the roller to rotate counterclockwise, causing the two L-shaped hinge strips 601 to fold. At the same time, the rain cover is rolled up to the side of the roller 3, thus quickly storing the rain cover 4. Then, the L-shaped rod 807 is released, and the vertical bar of the L-shaped rod 807 moves to the appropriate slot 808 through the rebound force of the compression spring 806, which can quickly fix the stored rain cover 4.

[0052] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
