Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors, and more specifically, to a door opener capable of conveniently controlling a clutch function. 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 realize the opening and closing of 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 the power goes out, 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 which is simple to install, easy to use and has a clutch function and can conveniently control the clutch function.

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

[0007] A door opener capable of conveniently controlling a clutch function comprises a driving device, a mounting plate, a column, a height adjustment structure and a pin; 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; the height adjustment structure is arranged on one of the columns, and an annular groove matched with the pin is arranged on the column;

[0008] It also includes a reset structure, which is arranged between the pin or the height adjustment structure and the mounting plate, and realizes automatic reset of the height adjustment structure driven by the pin.

[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, the reset structure includes a reset spring and a guide column for accommodating the reset spring. The reset spring is arranged on the guide column, and the other end of the reset spring contacts the pin.

[0012] Furthermore, the reset structure includes a reset spring, which is arranged between the internal thread column of the height adjustment structure and the protrusion of the column on which the height adjustment structure is set.

[0013] Furthermore, the column is cylindrical as a whole, and is provided with at least two annular grooves cooperating with the pins.

[0014] Further, the distance between at least two annular grooves is greater than the distance at which the drive device disengages from the meshing of the rack horizontally mounted on the door.

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

[0016] Furthermore, at least 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.

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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0038] like Figures 1 to 11 As shown, a door opener capable of conveniently controlling a clutch function comprises a driving device 1, a mounting plate 2, a column 3, a height adjustment structure 4 and a pin 5; the driving device 1 is arranged on the mounting plate 2 and connected through the column 3, and the driving device 1 adjusts the installation height through the height adjustment structure 4; the height adjustment structure 4 is arranged on one of the columns 3, and an annular groove 31 cooperating with the pin 5 is arranged on the column 3;

[0039] It also includes a reset structure 7, which is arranged between the pin 5 or the height adjustment structure 4 and the mounting plate 2, and realizes the automatic reset of the height adjustment structure driven by the pin 5. That is, the integration and reuse are realized by the column 3 and the height adjustment structure 4 as a whole, and the fine-tuning height and the clutch function during installation are realized, which will effectively reduce the complexity of the overall design, reduce the occupied volume as much as possible, and can improve the convenience of installation and reduce the difficulty of installation. And the convenience of the clutch function operation is improved by the reset structure 7. Specifically, after the motor 11 of the drive device 1 is installed, the output is driven by the worm gear 12 and the output shaft 13 is driven. The output shaft 13 is provided with a gear, and the gear is engaged with the rack installed horizontally on the door, and the rack drives the door to move. When there is a power outage and the drive device 1 cannot operate, by pulling out the pin 5, lightly pressing down a certain distance of the drive device 1, the output shaft 13 of the drive device 1 is separated from the rack installed horizontally on the door, and the corresponding door can be moved manually. At this time, the pin 5 pulled out can be reinserted into the annular groove 31 designed when it is in the clutch state. When the driving device 1 can be operated again, as long as the pin 5 is removed and the user does not press the driving device 1 lightly, the reset structure 7 will automatically rebound the output shaft 13 of the driving device 1 to a position that meshes with the rack installed horizontally on the door, thereby realizing an efficient and convenient clutch function.

[0040] 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. The stud 41 and the internal thread column 42 are used in conjunction with each other. That is, through the coordination of the stud 41 and the internal thread column 42, the height fine-tuning during installation is achieved, so that it can better mesh with the gear of the rack on the door during installation, and the installation is convenient. In the specific design, only threads can be set on the corresponding parts of the stud 41 and the internal thread column 42. Specifically, Figure 1 , 6 , 9, and 10 are both acceptable, which can mainly realize that the drive device 1 can be moved up and down, and local fine-tuning can be performed during installation.

[0041] In actual 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 upward 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.

[0042] Preferably, taking the reset structure 7 being disposed between the pin 5 and the mounting plate 2 as an example, Figures 1 to 7As shown. At this time, the column 3 of the height adjustment structure 4 is provided, and is integrally formed with the internal threaded 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 with 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 threaded column 42 forms a screw rod-like effect, and another threaded through hole is provided 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.

[0043] The column 3 is cylindrical as a whole, and an annular groove 31 is provided on it to cooperate with the pin 5. Generally, two annular grooves 31 are provided. In this way, the clutch function is realized. That is, the installation height of the drive device 1 is roughly positioned by the annular groove 31 provided as a whole, and 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.

[0044] At this time, the reset structure 7 includes a reset spring 71 and a guide column 72 for accommodating the reset spring 71. The reset spring 71 is arranged on the guide column 72, and the other end is in contact with the pin 5. The reset movement of the entire drive device 1 is controlled by the elastic force of the reset spring 71. Specifically, when the pin 5 is on the annular groove 31 at the top of the entire column 3, the drive device 1 is meshed with the rack. When the pin 5 is pulled out, due to the gravity of the drive device 1, the drive device 1 can be separated from the rack by just pressing it lightly, and then the pin 5 can be inserted into another corresponding annular groove 31 to lock it. When the drive device 1 resumes operation, as long as the pin 5 is pulled out, the reset spring 71 will push the drive device 1 to its original position, and the pin 5 can be inserted. The insertion and removal operation of the pin 5 can be achieved by setting a wrench 6 to facilitate operation.

[0045] Preferably, the reset structure 7 can also be arranged between the height adjustment structure 4 and the mounting plate 2, such as Figure 8 , 10 As shown (the reset spring 71 is not shown below the height adjustment structure 4). That is, the reset structure 7 only includes the reset spring 71, which is set between the internal thread column 42 of the height adjustment structure 4 and the protrusion of the column 3 on which the height adjustment structure 4 is set. The reset spring 71 can be telescoped to control the height adjustment structure 4 up and down, and the corresponding pin 5 has the same function as the above-mentioned reset structure 7 set between the pin 5 and the mounting plate 2.

[0046] The specific setting of the reset spring 71 can be set to be compression reset or spring reset according to actual conditions.

[0047] In the specific design, there are at least two annular grooves 31, that is, multiple annular grooves 31 can be set to be compatible with installation environments of multiple sizes. In practice, two annular grooves 31 can be customized, and multiple annular grooves 31 can be used as universal parts. The distance between at least two annular grooves 31 is greater than the distance at which the drive device 1 is disengaged from the meshing of the rack installed horizontally on the door.

[0048] Preferably, two or more columns 3 are used. The columns 3 bear horizontal forces without sliding in the horizontal direction, and can also achieve up and down guidance. The force is borne in the horizontal direction throughout the whole process, and the driving device 1 will not be offset. In order to facilitate the use of the pin 5, a wrench 6 can be provided, and the wrench 6 is connected to the pin 5, and the pin 5 is moved and controlled by the wrench 6. In the specific setting, the driving device 1 is correspondingly 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.

[0049] 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.

[0050] In summary, this solution reduces the complexity of installation and achieves convenience of installation through the height adjustment structure 4, the pin 5 and the reset structure 7, and improves the service life of the device by simplifying the overall structure, and has a clutch function that is more convenient and quick to operate.

[0051] 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.
