Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of doors and windows, and in particular relates to a tightening and fixing type transmission device and a handle device. Background Art
[0002] The door and window actuator is generally installed in the installation cavity of the door and window sash profile as an intermediate transmission component between the handle and the lock point. The handle outside the profile is connected to the gear of the actuator through the transmission shaft. The rotation of the handle drives the gear and the rack matched with the gear to move, thereby driving the transmission bar and the lock point to realize the opening and closing control of the door and window lock.
[0003] In order to facilitate the installation and fixation between the transmission and the profile, clamping plates are generally provided at both ends of the transmission housing in the prior art. During the installation process, the transmission as a whole is first placed into the installation cavity of the profile, and then the rivets connected to the clamping plates are screwed to drive the clamping plates to rotate, so that the protruding ends of the clamping plates extend out of the transmission and are tightly pressed against the profile frame. At the same time, the transmission cover and the limiter surface of the profile groove are combined to clamp the transmission on the profile to fix the transmission.
[0004] However, the above clamping and fixing method of the transmission has poor flexibility. The size of the clamping piece must correspond to the width of the profile's installation cavity. If the width of the installation cavity on the profile is too large, the protruding ends of the clamping piece may not be able to press against the profile frame or the pressing effect may be poor, resulting in the transmission being unable to be effectively fixed to the profile and prone to loosening. If the width of the installation cavity on the profile is too small, the best pressing parts of the protruding ends of the clamping piece may not be able to press against the profile frame, greatly weakening the fixing effect of the clamping piece. In addition, the method of fixing the clamping piece to the profile can only achieve one-way locking and fixing of the transmission. The transmission may be pulled off balance in the profile's installation cavity due to the pulling of the handle. It can be seen that there is still a stability defect in fixing the transmission using only the clamping piece.
[0005] Therefore, it is necessary to propose a transmission device that is simple and convenient to operate, has higher adaptability and better stability to solve the above technical problems. Utility Model Content

It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0050] Example 1
[0051] See also Figure 1-Figure 7 The present embodiment discloses a tightening and fixing type transmission device, comprising a housing 2, a cover 1 and two tightening components 3; the cover 1 is arranged on the outside of the housing 2 and corresponds to the outer surface of the mounting cavity 301 of the profile in the installed state; the two tightening components 3 are arranged in the housing 2, respectively located at the two ends of the housing 2, for details, see Figure 1 .
[0052] The tightening assembly 3 of this embodiment includes a control member 301 and two tightening members 302; the housing 2 and the cover 1 are both provided with through holes 5, which correspond to the control member 301 and are used for inserting tools to operate the control member 301. In addition, the housing 2 is provided with guide openings 4 at corresponding positions of the side surfaces adjacent to the tightening members 302; the control member 301 in each tightening assembly 3 cooperates with the two tightening members 302 through a linkage structure; the two tightening members 302 are prompted to tilt and expand outward from the housing 2 or tilt and retract inward from the housing 2 along the corresponding guide openings 4 by screwing the control member 301, so as to achieve the fixing or loosening of the actuator.
[0053] See also Figure 2-Figure 5 , further, the linkage structure of the present embodiment includes a linkage member 303; two tension members 302 are respectively arranged on both sides of the linkage member 303, and the side of the tension member 302 away from the face cover 1 is rotatably connected to the linkage member 303. Specifically, the linkage member 303 of the present embodiment is connected with the control member 301 through a threaded structure; wherein, the control member 301 is provided with an external thread structure, such as a screw, and an inner hexagonal countersunk hole is provided at one end close to the face cover 1, so that it is convenient to use a tool to extend from the outside and screw it; the linkage member 303 is provided with a threaded hole. The threaded structure is simple and reliable, and it is convenient to control. By screwing the control member 301 and using the threaded structure to cause the linkage member 303 to move in a direction close to or away from the face cover 1, the two tension members 302 are driven to rotate, causing the side of the tension member 302 close to the face cover 1 to open outward or shrink inward.
[0054] See also Figure 2-Figure 7, further, a slot 3031 is provided on the linkage member 303; a rotating part 3021 is provided on the side of the two tightening members 302 away from the face cover 1, and the rotating parts 3021 of the two tightening members 302 are respectively arranged on both sides of the slot 3031. Specifically in this embodiment, there are preferably two slots 3031 on the linkage member 303, and the two slots 3031 are respectively arranged at both ends of the linkage member 303; there are two rotating parts 3021 on each tightening member 302, and the two rotating parts 3021 are respectively arranged in the two slots 3031. Through the cooperation between the slot 3031 and the rotating part 3021, when the linkage member 303 moves toward or away from the face cover 1, the two tightening members 302 are driven to rotate, thereby achieving the effect of spreading outward or contracting inward.
[0055] As another embodiment, the linkage member 303 and the tightening member 302 may be connected in other ways to achieve the rotation of the tightening member 302, such as by shaft-hole matching, hinge connection, etc.
[0056] A plurality of gear structures 3022 are arranged on one side of the tightening member 302 close to the cover 1, and the gear structures 3022 are arranged along the length direction of the tightening member 302. The arrangement of the gear structures 3022 can enhance the pressing force with the profile when the tightening member 302 is opened, which is beneficial to enhance the stability of the transmission after locking.
[0057] See also Figure 4-Figure 5 In order to further improve the stability of the transmission device, a limiting portion 3011 is provided at one end of the control member 301 of this embodiment away from the face cover 1, and the limiting portion 3011 extends along the axial direction of the control member 301. When locking and fixing the transmission device, the control member 301 is screwed to move to the side away from the face cover 1, and the limiting portion 3011 is prompted to pierce the bottom surface of the installation cavity 301. In the process of locking and fixing the transmission device, while the tightening member 302 is stretched outward and pressed against the profile, the limiting portion 3011 pierces the bottom surface of the installation cavity 301, and the limiting portion 3011 is used to reinforce the position of the transmission device, so that the height direction and thickness direction (radial and axial direction of the transmission shaft 8 of the handle device) of the transmission device can be limited, and its stability is greatly enhanced, especially it can avoid being pulled off by the handle 7 of the handle device. In this embodiment, the thickness direction of the transmission device is reinforced and locked by piercing directly, which has a simple structure and convenient installation, does not need to improve the profile, and has a good effect.
[0058] As another embodiment, a limiting hole can be provided on the bottom surface of the profile's installation cavity 301, and the limiting hole corresponds to the limiting portion 3011; when locking and fixing the actuator, the control member 301 is screwed to move to the side away from the cover 1 until the limiting portion 3011 is inserted into the limiting hole. The limiting hole is pre-processed on the bottom surface of the profile's installation cavity 301, and the limiting portion 3011 of the control member 301 directly extends into the limiting hole during installation, thereby achieving reinforced limiting of the actuator.
[0059] To meet market demand, the window frames on the market are getting narrower and narrower, and the handle 7 on the window frame is a fixed style without a base, that is, the handle 7 is directly connected to the gear of the transmission device after the transmission shaft 8 passes through the profile, which not only realizes the transmission connection between the handle 7 and the transmission device, but also realizes the installation of the handle 7. However, since the handle 7 without a base is directly connected to the gear of the transmission device, the transmission device is subjected to a greater force from the handle 7, and a higher stability requirement is placed on the transmission device.
[0060] In the tightening and fixing type transmission of the present embodiment, when the tightening assembly 3 and the profile are pressed against each other to realize locking of the transmission, the limiting portion 3011 of the control member 301 and the limiting portion of the bottom surface of the installation cavity 301 are simultaneously utilized to realize bidirectional locking of the transmission, thereby effectively eliminating looseness or deviation of the transmission.
[0061] See also Figure 4-Figure 5 The side of the guide opening 4 close to the cover 1 is tilted outward from the housing 2 to form a first guide surface 401; during the locking and fixing process of the actuator, the tensioning member 302 is stretched outward along the first guide surface 401. The side of the guide opening 4 away from the cover 1 is tilted outward from the housing 2 to form a second guide surface 402, so as to guide the support and contraction of the tensioning member 302. In this way, both sides of the guide opening 4 are tilted, which is conducive to forming a guiding inclined surface when the tensioning member 302 is stretched outward and contracted inward, ensuring that the tensioning member 302 can be smoothly tilted outward and contracted inward.
[0062] See also Figure 4-Figure 5 The present embodiment also discloses a handle device, including a handle 7, a transmission shaft 8 and the above-mentioned tightening and fixing transmission device. One end of the transmission shaft 8 is connected to the handle 7, and the other end of the transmission shaft 8 is connected to the gear of the tightening and fixing transmission device after passing through the profile. The handle device of the present embodiment also includes components such as a rack and a transmission bar, and the details can be referred to the prior art. In addition, the handle device of the present embodiment can be a one-way transmission or a two-way transmission, and the present utility model does not limit this.
[0063] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
