Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors, and more specifically, to a door opener with adjustable installation height. Background Art

[0002] Door openers are usually used to realize the electric opening and closing of various door bodies. The main structure of the existing door opener includes a motor and a horizontally arranged drive shaft. The motor and the drive shaft are linked to each other through a large number of gear sets, worm gears and other transmission components to reduce speed. The motor drives the drive shaft to rotate, and then drives the door leaf to open and close the door. In actual use, the existing door openers have the following defects: the installation of the door opener is very troublesome and requires extremely high precision, otherwise it will cause the door to be unusable, or it will be jammed when opening the door. Furthermore, when there is a power outage or a control system failure, the door cannot be opened or closed manually, causing inconvenience to the user. Especially for school door switches, once a power outage occurs, it will cause huge trouble.

[0003] The current solution to power outages in the market is to use a manual clutch device, which relies on a clutch to control the clutch of the worm shaft and the sprocket. The contact area between the clutch and the sprocket is large, and it is difficult to use a clutch key to clutch, which is very inconvenient to use.

[0004] Therefore, better technical solutions need to be proposed to solve these problems. Utility Model Content

[0005] The utility model overcomes the shortcomings of the prior art and provides a door opener with adjustable installation height and a clutch function, which is simple to install and convenient to use.

[0006] The technical solution of the utility model is as follows:

[0007] A door opener with adjustable installation height comprises a driving device, a mounting plate, a column and a height adjustment structure; the driving device is arranged on the mounting plate and connected through the column, and the driving device adjusts the installation height through the height adjustment structure;

[0008] One end of the column is arranged on the mounting base, and the other end is connected to the driving device. A height adjustment structure is arranged on one end of one of the columns away from the mounting plate.

[0009] Furthermore, the height adjustment structure includes a stud connected to the placement position and an internal threaded column for up and down adjustment, and the stud and the internal threaded column are used in conjunction with each other.

[0010] Furthermore, the position of the internal threaded column movement determines the final height of the door opener installation adjustment.

[0011] Furthermore, a vertical column of the height adjustment structure is provided and is integrally formed with the internally threaded column of the height adjustment structure.

[0012] Furthermore, the column of the height adjustment structure passes through the driving device.

[0013] Furthermore, it includes a pin, and the column is cylindrical as a whole, and an annular groove matching the pin is arranged on it.

[0014] Furthermore, there is at least one annular groove.

[0015] Furthermore, the inner diameter of the annular groove is greater than the outer diameter of the pin.

[0016] Furthermore, two columns are used to bear horizontal forces and achieve up and down guidance.

[0017] Furthermore, the motor of the driving device rotates and outputs, and drives the output shaft through the worm gear. The output shaft is provided with a gear, which meshes with a rack horizontally installed on the door, and the rack drives the door to move.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The utility model reduces the complexity of installation and realizes convenience of installation through the height adjustment structure, and realizes integrated reuse through the column and the height adjustment structure, which will effectively reduce the complexity of the overall design, minimize the occupied volume, and improve the convenience of installation and reduce the difficulty of installation.

[0020] The utility model simplifies the overall structure, increases the service life of the device, and has a clutch function that is more convenient and quick to operate. The annular groove is provided to roughly locate the approximate installation height of the drive device as a whole, and is fixed by a pin. The overall operation is simple and convenient, and the installation is quick. The inner diameter of the annular groove is larger than the outer diameter of the pin, and this difference can be used as a fine-tuning distance for installing the drive device. During normal use, the pin is always in it, and the door can be opened and closed by powering on. When a power outage or other special circumstances make it impossible to use the device, just pull out the pin, and the entire drive device sinks a certain distance to disengage the gears. After returning to normal, just lift the drive device up a certain distance and reinsert the pin. The drive device is subjected to force in the entire horizontal direction, and will not be offset.

[0029] The embodiments of the present invention are described in detail below, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and cannot be used as a limitation of the present invention.

[0030] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those skilled in the art in the field to which the utility model belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as the meaning in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless defined as herein.

[0031] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" are usually used to refer to the upper and lower parts of the door when the door is in an installed state, and the end of the door close to the ground can be the lower end, and the end away from the ground can be the upper end. "Inside and outside" refer to the inside and outside of related parts. In addition, the terms "first", "second", etc. used in the embodiments of the present disclosure are used to distinguish one element from another element, and do not have order and importance.

[0032] The reference numerals of the steps mentioned in each embodiment are only for the convenience of description and have no substantial sequence connection. Different steps in each specific embodiment can be combined in different sequences to achieve the utility model purpose of the utility model. In addition, some structures and modules not described in detail in the utility model can be implemented by conventional technical means, so they will not be described in detail.

[0033] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figures 1 to 7 As shown, a door opener with adjustable installation height includes a drive device 1, a mounting plate 2, a column 3 and a height adjustment structure 4; the drive device 1 is arranged on the mounting plate 2 and connected through the column 3, and the drive device 1 adjusts the installation height through the height adjustment structure 4.

[0035] One end of the column 3 is arranged on the mounting base, and the other end is connected to the driving device 1, and a height adjustment structure 4 is arranged on one end of the column 3 away from the mounting plate 2. That is, the column 3 and the height adjustment structure 4 are integrated and reused, which will effectively reduce the complexity of the overall design, minimize the occupied volume, and improve the convenience of installation and reduce the difficulty of installation.

[0036] Specifically, the height adjustment structure 4 includes a stud 41 connected to the placement position and an internal thread column 42 for up and down adjustment, and the stud 41 is used in conjunction with the internal thread column 42. That is, through the cooperation of the stud 41 and the internal thread column 42, the height fine adjustment during installation is achieved, so that it can better mesh with the gear on the door during installation, and the installation is convenient.

[0037] During installation, the position of the internal thread column 42 determines the final height of the door opener installation adjustment, that is, one end of the internal thread column 42 contacts the installed drive device 1, and it moves up and down on the stud 41 through the thread. After confirming the adjustment position, it is difficult to move the drive device 1 up as long as the internal thread column 42 is not rotated. In the specific design, a high-precision screw can be used, so that even if the internal thread column 42 rotates, the movement distance is small and it will not have a significant impact on the gear meshing.

[0038] As a preference, Figure 6 As shown, the column 3 of the height adjustment structure 4 is provided, and is integrally formed with the internal thread column 42 of the height adjustment structure 4, which helps to improve the overall rigidity and facilitate installation. That is, the installation height of the drive device 1 is fine-tuned and controlled by rotating the stud 41, such as by fixing the drive device 1 and the column 3 together through the pin 5, and then the gear meshing is achieved by fine-tuning the stud 41. The column 3 of the height adjustment structure 4 runs through the drive device 1, which reduces the overall design complexity, reduces the overall volume, effectively withstands the horizontal force, and is convenient for installation. In the specific design, the column 3 and the stud 41 of the height adjustment structure 4 can also be integrally formed, that is, the internal thread column 42 forms a screw rod-like effect, and another threaded through hole is set at the placement position of the motor 11 to connect the stud 41, adjust the use depth of the stud 41, and then adjust the installation height of the drive device 1.

[0039] Preferably, the column 3 includes a pin 5 and is cylindrical as a whole, and an annular groove 31 is provided thereon to cooperate with the pin 5. In this way, the clutch function is realized. That is, the installation height of the drive device 1 is roughly positioned by the provided annular groove 31 as a whole, and is fixed by the pin 5. The overall operation is simple and convenient, and the installation is quick. The inner diameter of the annular groove 31 is larger than the outer diameter of the pin 5, and this difference can be used as a distance for fine-tuning the installation of the drive device 1.

[0040] In the specific design, there is at least one annular groove 31, that is, multiple annular grooves 31 can be set to be compatible with installation environments of multiple sizes. In practice, one annular groove 31 can be customized, and multiple annular grooves 31 can be used as a universal part.

[0041] Preferably, two columns 3 are used, which can withstand horizontal forces, will not slide horizontally, and can also achieve up and down guidance. That is, as a whole, during normal use, the pin 5 is always in it, and the door can be opened and closed by powering on. When it cannot be used due to special circumstances such as power outages, it is only necessary to pull out the pin 5, and the entire drive device 1 sinks a certain distance to disengage the gears. After returning to normal, it is only necessary to lift the drive device 1 up a certain distance and reinsert the pin 5. The drive device 1 is subjected to force in the horizontal direction throughout the process, and will not be offset. In order to facilitate the use of the pin 5, a wrench 6 can be provided, which is connected to the pin 5, and the pin 5 is moved and controlled by the wrench 6. In the specific setting, the drive device 1 is provided with a column placement hole 14 for placing the column 3, and a pin hole 15 is provided in the hole to facilitate the use of the pin 5.

[0042] Specifically, the motor 11 of the driving device 1 rotates and outputs, and then drives the output shaft 13 through the worm gear 12. The output shaft 13 is provided with a gear, which meshes with a rack horizontally installed on the door, and the rack drives the door to move. The overall moving structure is simplified as much as possible to increase the overall service life and facilitate subsequent maintenance.

[0043] In summary, this solution reduces the complexity of installation and achieves convenience of installation by means of the height adjustment structure 4, and increases the service life of the device by simplifying the overall structure, and has a clutch function that is more convenient and quick to operate.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
