Description

Technical Field

[0001] This utility model relates to the field of installation auxiliary equipment technology, and in particular to an auxiliary installation device for roller shutter doors. Background Technology

[0002] A roller shutter door, also known as a rolling shutter door, is a type of door consisting of multiple articulated door panels connected together. This door can rotate up and down within a fixed track, using a roller at the top of the door as its axis.

[0003] Roller shutters consist of several key components, including curtain panels, seat plates, guide rails, supports, rollers, housings, control boxes, roller motors, limit switches, lintels, manual quick-release devices, push-button switches, and safety devices.

[0004] In practical applications, the installation of a roller shutter door first requires raising the rolled-up door leaf assembly to a suitable height. Next, bolts are used to secure the end leaf assembly to the roller shaft. Finally, the roller shutter door is wound around the outside of the roller shaft by opening it, completing the initial installation. The most challenging aspect of this process is raising the door leaf assembly.

[0005] In practice, operators typically use a pull rope with movable loops to raise the roller shutter door. The operator places a loop on each end of the roller shutter door leaf and the outer side of the roller shaft. By moving the loops, the height of the loops is shortened, thus reducing the distance between the door shaft and the roller shutter door, allowing the door to be raised. It is worth noting that in actual use, the lack of a limiting mechanism between the loops and the door leaf means that when a single loop is tightened too much, the door leaf tilts and may easily separate from the loop under its own weight. Therefore, the solution is either for two operators to work together to tighten the loops simultaneously, or for a single person to slowly and gradually raise the door leaf.

[0006] Therefore, we believe that there is a need for an auxiliary installation device for roller shutters that is easy to operate, reduces reliance on manual labor, and stably lifts the roller shutter door. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model proposes an auxiliary installation device for roller shutter doors. This device is easy to operate, effectively reduces reliance on manual labor, and solves the problem of excessive dependence on operator experience in existing devices.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A roller shutter door auxiliary installation device includes a support base with a bracket at the upper end of the support base. The roller shutter door is placed in a groove on the upper side of the bracket. It also includes a positioning shaft with a lifting mechanism on each side of the positioning shaft. The positioning shaft is fitted with an installation component. The bracket is fixedly connected to the installation component. A support plate is fixedly connected to the side of the installation component away from the bracket. The side of the support plate near the bracket has anti-slip texture. When the bracket and the support plate are on the same vertical plane, a positioning hole is formed through the support plate. The support base has limit holes for the positioning holes. A limit pin is inserted into each positioning hole and its corresponding limit hole.

[0010] Preferably, each lifting mechanism includes a driven ring rotatably connected to a positioning shaft, and a support rod is rotatably connected to the left and right sides of each driven ring. Each lifting mechanism also includes two lead screws arranged left and right with axial orientation. A slider is sleeved on the outside of the lead screw and screwed to the lead screw. The upper end of each slider is rotatably connected to the corresponding support rod. The upper end of the bearing base has a slide rail for the slider, and the slide rail is embedded in the slide rail and slidably connected to the bearing base.

[0011] Preferably, when the bracket and the support plate are on the same horizontal plane, the bracket abuts against the upper surface of the support plate and the bearing base.

[0012] Preferably, each of the lifting mechanisms further includes a synchronous bevel gear set, and the two lead screws in each lifting mechanism rotate synchronously through the synchronous bevel gears. A synchronous transmission chain set is provided between the two lifting mechanisms, and the two synchronous bevel gear sets are connected by the synchronous transmission chain set.

[0013] Preferably, the lateral width of the bracket is less than the lateral width of the support plate, and the difference in horizontal distance between the rear end face of the support plate and the rear end face of the bracket is not less than fifty centimeters.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model designs a device characterized by installing a mounting component on the outside of a positioning shaft. One end of the mounting component is fixedly connected to a bracket, and the other end is connected to a support plate. This support plate is designed to facilitate standing operation for the operator. The device also includes a limiting pin for precisely fixing the position of the support plate. When the support plate and the bracket are on the same vertical plane, the operator can stand on the support plate and lift synchronously with the bracket, thereby improving work efficiency. Correspondingly, when the bracket and the support plate are at the same horizontal position, the overall longitudinal height of the device is reduced, making it easier to store and transport.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Please refer to Figure 1 , Figure 2A roller shutter door auxiliary installation device is disclosed, the structure of which is consistent with existing technology. The device consists of a support base 8, with a bracket 2 at the upper end of the support base 8. In practical application, the rolled-up roller shutter door 1 can be placed in the groove above the bracket 2, and then the roller shutter door 1 can be easily lifted by the upward movement of the bracket 2. After lifting, the roller shutter door 1 will be moved to a predetermined position, thus facilitating subsequent installation work.

[0026] Compared to existing technologies, this device features a unique positioning shaft 10, with a lifting mechanism 7 at each of its front and rear ends. The lifting mechanism 7 can adjust the height of the positioning shaft 10, and the two lifting mechanisms 7 work together to ensure that the positioning shaft 10 remains stable in the front-rear axial direction.

[0027] In addition, an installation component 3 is provided on the outside of the device. The installation component 3 is fixedly connected to the bracket 2, and a support plate 6 is fixedly connected to the end of the installation bracket away from the bracket 2.

[0028] It is worth noting that, in practical applications, the positioning shaft 10 and the mounting component 3, as well as the positioning shaft 10 and the lifting mechanism 7, can be flexibly rotated. This allows the device to change the state of the mounting component 3 by rotating it while keeping its position unchanged.

[0029] Therefore, regarding the positional relationship between bracket 2 and support plate 6, if they are on the same vertical plane, the operator can stand on support plate 6 and use it to raise the height, thus facilitating installation work. Similarly, when bracket 2 and support plate 6 are on the same horizontal plane (e.g., ...), ... Figure 2 When the device is in its vertical height (as shown), the overall height of the device will be reduced, making it easier to store and move.

[0030] In addition, the lateral width of the constraint bracket 2 of this device is designed to be smaller than the lateral width of the support plate 6, ensuring that the difference in horizontal distance between the rear end face of the support plate 6 and the rear end face of the bracket 2 is not less than fifty centimeters, thereby providing sufficient standing space for the operator.

[0031] In addition, anti-slip texture 4 is designed on the side of the support plate 6 near the bracket 2 to increase the coefficient of friction and prevent slippage.

[0032] In addition, the support plate 6 has a through positioning hole 11, and the bearing base 8 has a corresponding limiting hole 12. When the bracket 2 and the support plate 6 are in the same vertical plane, the positioning hole 11 and the limiting hole 12 are also in the same vertical plane. At this time, a limiting pin 5 can be inserted into each positioning hole 11 and the corresponding limiting hole 12 to ensure the stability and accuracy of the device. Through the cooperation of the limiting pin 5 with the limiting hole 12 and the positioning hole 11, the rotation of the mounting part 3 can be effectively restricted.

[0033] Specifically, each lifting mechanism includes a driven ring 704, such as Figure 1 , Figure 2 , Figure 5 As shown, this device uses a driven ring 704 to be rotatably connected to the positioning shaft 10. Correspondingly, the positioning shaft 10 is fixedly connected to the mounting part 3 to constrain the position of the mounting part 3.

[0034] In addition, such as Figure 5 As shown, a bearing is provided on the inner side of the driven ring 704. The driven ring 704 is rotatably connected to the positioning shaft 10 through the bearing. This design can effectively reduce the frictional loss generated when the positioning shaft 10 and the driven ring 704 rotate relative to each other.

[0035] At the same time, such as Figure 3 , Figure 4 As shown, each lifting mechanism also includes two lead screws 702 arranged on the left and right with axial orientation, and a slider 701 is screwed to the outside of the lead screw 702 to ensure a stable connection.

[0036] At this time, as Figure 3 , Figure 5 , Figure 6 As shown, in conjunction with the support rods 705 set on the left and right sides of each driven ring 704, the other end of the support rod 705 is rotatably connected to the slider 701. Based on the rotatable connection between the support rod 705 and the driven ring 704, and taking advantage of the constant length of the support rod 705, the projection length of the support rod 705 in the vertical direction can be changed by adjusting the distance between the two sliders 701 in a single lifting mechanism, thereby precisely controlling the height of the positioning shaft 10.

[0037] It is worth noting that, such as Figure 3 As shown, each lead screw 702 is equipped with bearings at both ends. The lead screw 702 is connected to the bearing base 8 through the bearings to realize the rotation function. At the same time, the bearings also play a role in fixing and constraining the position of the lead screw 702.

[0038] Specifically, such as Figure 3 , Figure 6 As shown, in order to prevent the slider 701 from rotating with the lead screw 702 and to ensure that the left and right positions of the slider 701 can be adjusted during the rotation of the lead screw 702, a slide rail 9 is designed on the upper end of the bearing base 8. The slider 701 is embedded in it and forms a sliding connection with the bearing base 8.

[0039] It should be pointed out that, such as Figure 6 As shown, each slider 701 adopts a Chinese character-shaped structure. This structural shape increases the contact area with the slide rail 9, thereby further strengthening the positional constraint force of the slide rail 9 on the slider 701 and ensuring that the slider 701 will not rotate.

[0040] In addition, taking advantage of the constant length of the lead screw 702, when the bracket 2 and the support plate 6 are restricted to the same straight line, that is, when the device is in the storage state, the bracket 2 and the support plate 6 will fit tightly against the upper surface of the bearing base 8, ensuring that the mounting part 3 will not rotate arbitrarily relative to the bearing base 8 during the handling or storage process.

[0041] Specifically, to achieve the left and right movement of the slider 701, i.e., to achieve the rotation of the two lead screws 702 within a single lifting mechanism 7, this device includes a synchronous bevel gear set 703. The two lead screws 702 within each lifting mechanism 7 rotate synchronously through the synchronous bevel gear to ensure that the rotation speed of the two lead screws 702 remains consistent, avoiding stroke conflict between the two support rods 705. Furthermore, the rotation of both lead screws 702 within a single lifting mechanism 7 can be achieved by rotating a single lead screw 702.

[0042] In addition, to ensure that the positioning shaft 10 always remains in the front-rear axis and that the two lifting mechanisms 7 operate at the same speed, a synchronous transmission chain group 13 is added between the two lifting mechanisms 7. The two synchronous bevel gear groups 703 are connected by the transmission chain group to ensure that the two lifting mechanisms 7 can work in coordination.

[0043] It must be pointed out that, such as Figure 2 , Figure 3 , Figure 4 As shown, each synchronous bevel gear set 703 consists of two follower bevel gears keyed to the corresponding lead screw 702, and a driven bevel gear that plays the main transmission role. These synchronous bevel gear sets 703 achieve synchronization through friction, ensuring smooth meshing of the gears during gear shifting, thereby reducing impact between gears and extending the service life of the gearbox. Correspondingly, the synchronous transmission chain set 13 consists of a transmission chain and its inner sprockets, with the sprockets forming a transmission connection with the transmission chain. Therefore, by setting a synchronous shaft between the sprockets and the driven bevel gears, and ensuring that the synchronous shaft is keyed to the corresponding sprockets and driven bevel gears, the synchronous rotation of the four lead screws 702 can be achieved.

[0044] It is worth noting that the upper end of the synchronous shaft is designed to protrude beyond the protective shell. This design makes it easy for operators to rotate the synchronous shaft in actual operation, whether by electric or manual means.

[0045] In the practical application of this utility model:

[0046] First, the operator needs to unfold the device from its retracted state. During this process, the four lead screws 702 are rotated synchronously by rotating the synchronous shaft. At this time, the positioning shaft 10 continues to move upward, the support plate 6 remains in contact with the bearing platform, and the distance between the bracket 2 and the bearing platform gradually increases.

[0047] Next, when the positioning shaft 10 rises to the position where the support plate 6 and the bracket 2 are on the same vertical plane, the operator needs to stop the rotation of the synchronous shaft. Then, rotate the synchronous shaft in the opposite direction until the support plate 6 is in close contact with the bearing platform again.

[0048] Subsequently, the operator places the rolled-up shutter door 1 on top of the bracket 2 and rotates the synchronous shaft until the rolled-up shutter door 1 on top of the bracket 2 is transported to the appropriate installation position.

[0049] Afterwards, the operator stands above the support platform and inserts the limit pin 5 into the limit hole 12 and the positioning hole 11;

[0050] Finally, the operator stood on the support plate 6 and began to install the roller shutter door 1.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. Considering the characteristics of utility model patents, such as short examination time, fast authorization, different scope of protection, confidentiality of the examination process, and low cost, the scope of the present invention is defined by the appended claims and their equivalents.
