Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and in particular to a transmission mechanism and a transmission device. Background Art

[0002] During the opening process of profile doors and windows, it is usually necessary to drive the transmission mechanism with a handle to achieve the overall transmission of the door and window hardware. Most of the transmission mechanisms in the prior art are equipped with a gear and rack meshing transmission, and a hexagonal hole that can cooperate with the square shaft of the handle is set on the gear, so as to achieve the movement of the handle-driven transmission mechanism. During the design process, the transmission mechanism is required to meet the specified stroke and ensure the force condition of the square shaft hole. Therefore, the transmission mechanism in the prior art usually has a larger size to meet the above requirements, which makes the space occupied by the transmission mechanism too large. When installing on the profile, the profile must be milled to meet the installation requirements. At the same time, the transmission parts must be cut and installed at both ends of the transmission mechanism, which will not only damage the cavity of the profile, but also greatly increase the installation time of the transmission mechanism. In addition, the gear and rack matching inside the transmission mechanism, and the gear and handle matching make the transmission mechanism have too many accessories inside, which is not only inconvenient to install, but also difficult to control the gap between internal components.

[0009] Furthermore, the connecting assembly includes: a second connecting member, on which a fastening protrusion is provided, and the fastening protrusion can be used to pass through a matching hole on the transmission member; and a second fixing member, which is passed through the connecting portion and connected to the second connecting member.

[0010] Furthermore, the second connecting member includes: a clamping end, which can be slidably clamped in the profile member; and a connecting end, which is connected to the clamping end, and the fastening protrusion is arranged on the connecting end.

[0011] Further, the connecting portion forms a limiting groove, the groove opening of which is opened toward the transmission member, the limiting groove is provided with a plurality of first limiting protrusions arranged at intervals, the connecting component is provided with a plurality of second limiting protrusions arranged at intervals, and when the connecting portion is sleeved on the connecting component, a second limiting protrusion is fitted between two adjacent first limiting protrusions, and / or a first limiting protrusion is fitted between two adjacent second limiting protrusions.

[0012] Furthermore, the connecting portion is provided with a connecting hole, the connecting component is inserted into the connecting hole, and the connecting component has a limiting end, and the limiting end can abut against the top wall of the connecting portion.

[0013] Furthermore, the connecting hole is a waist-shaped hole, and the length direction of the waist-shaped hole and the length direction of the movable part form an angle.

[0014] Furthermore, an elastic member is provided on the inner wall of the sliding groove, and an escape groove is provided on the side wall of the movable member. The elastic member is in a compressed state when abutting against the side wall of the movable member, and is in a relaxed state when abutting in the escape groove.

[0015] A transmission device, characterized in that it comprises: a profile member, on which a mounting wall and a mounting groove are provided; the transmission mechanism described above, wherein the side wall of the mounting shell abuts against the mounting wall, and the mounting shell is arranged on the top wall of the mounting groove; a transmission member, which can be slidably engaged in the mounting groove, and the transmission member is connected to the movable member.

[0016] The beneficial effects of the present invention are as follows: the limiting edge and the clamping strip can limit the movable part inserted in the sliding groove, so that the distance between the movable part and the bottom wall of the sliding groove can be adjusted according to actual needs, and the movable part can only move along the length direction of the sliding groove, ensuring the driving effect of the handle on the movable part. At the same time, a transmission rack is provided on the bottom wall of the movable part, and the output end of the handle can mesh with the transmission rack and drive the transmission rack to move, so that the transmission mechanism can move under the drive of the handle without the need for an additional gear structure. Since the transmission mechanism no longer has a structure with a large space occupation such as a gear, the thickness of the movable part in the transmission mechanism, the thickness of the mounting shell, and the spacing between the movable part and the mounting shell can be adjusted according to actual needs, so that the movable part can move on the mounting shell under the drive of the handle when it has a small height, and does not need to occupy the space in the profile part under the height limit of the mounting wall.

The locking assembly is inserted into the mounting shell and the mounting wall and connected to the handle, which can make the mounting shell stably and reliably connected to the mounting wall and stably installed on the profile. It can also reduce the possibility of relative displacement of the mounting shell relative to the output end of the handle, and enable the movable part to move reliably under the drive of the handle. According to the transmission mechanism of the present invention, since the transmission mechanism has a small height, the thickness of the transmission structure and its space occupied are significantly reduced, and there is no need to occupy the internal space of the profile, and the mounting shell can be stably connected to the mounting wall. Therefore, during the installation and use of the transmission mechanism of the present invention, there is no need to perform additional processing on the profile to form a larger transmission mechanism installation space, which ensures the strength of the profile itself and reduces the installation difficulty and processing cost. In addition, since the transmission mechanism of the present invention cooperates with the output end of the handle through the transmission rack provided on the movable part, there is no need to additionally set up other gear rack structures inside the transmission mechanism. Under the premise of ensuring the driving effect of the handle on the transmission mechanism, the number of internal accessories of the transmission mechanism is effectively reduced, and it is convenient to reduce the assembly gap between the accessories inside the transmission mechanism.

[0044] In this specification, all contents related to the door and window structure may be a door structure, a window structure, or a door structure and a window structure, and no specific limitation is made herein.

[0045] Reference below Figure 1-Figure 13 The specific structure of the transmission mechanism according to the embodiment of the present invention is described.

[0046] like Figure 1-Figure 13 As shown, Figure 1 A transmission mechanism is disclosed, which includes a mounting shell 1, a locking assembly and a movable part 3. The side wall of the mounting shell 1 can be used to abut against the mounting wall 110 of the profile member 100, the mounting shell 1 can be arranged on the profile member 100, the mounting shell 1 is formed with a sliding groove 11, and the tops of the two side walls of the sliding groove 11 are respectively provided with limiting edges 12. The locking assembly can be used to be inserted into the mounting shell 1 and the mounting wall 110 and connected to the handle 150. The movable part 3 is inserted into the sliding groove 11, and the two side walls of the movable part 3 are provided with a clamping strip 31 abutting against the limiting edge 12, and the bottom wall of the movable part 3 is provided with a transmission rack 32, and the transmission rack 32 can mesh with the output end of the handle 150.

[0047] It can be understood that the limiting edge 12 and the clamping strip 31 can have a limiting effect on the movable part 3 inserted through the sliding groove 11, so that the distance between the movable part 3 and the bottom wall of the sliding groove 11 can be adjusted according to actual needs, and the movable part 3 can only move along the length direction of the sliding groove 11, thereby having a limiting effect on the movement of the movable part 3 in the vertical direction, thereby ensuring the driving effect of the handle 150 on the movable part 3. At the same time, a transmission rack 32 is provided on the bottom wall of the movable member 3, and the output end of the handle 150 can mesh with the transmission rack 32 and drive the transmission rack 32 to move, so that the transmission mechanism can move under the drive of the handle 150 without the need for an additional gear structure. Since the transmission mechanism no longer has a structure that occupies a large space, such as a gear, the thickness of the movable member 3 in the transmission mechanism, the thickness of the mounting shell 1, and the spacing between the movable member 3 and the mounting shell 1 can be adjusted according to actual needs, so that the movable member 3 can move on the mounting shell 1 under the drive of the handle 150 when it has a small height, and does not need to occupy the space in the profile member 100 under the height limit of the mounting wall 110. The movable member 3 can be slidably inserted into the sliding groove 11, so that the movable member 3 will not have a relative displacement in the vertical direction relative to the mounting shell 1. At the same time, the locking assembly is inserted into the mounting shell 1 and connected to the mounting wall 110, so that the mounting shell 1 can be stably installed on the profile member 100. The locking assembly is passed through the mounting shell 1 and the mounting wall 110 and connected to the handle 150, so that the mounting shell 1 can be stably and reliably connected to the mounting wall 110 and firmly set on the profile member 100. It can also reduce the possibility of relative displacement of the mounting shell 1 relative to the output end of the handle 150, and enable the movable part 3 to move reliably under the drive of the handle 150.

[0048] According to the transmission mechanism of this embodiment, since the transmission mechanism has a small height, the thickness of the transmission structure and its space occupation are significantly reduced, and there is no need to occupy the internal space of the profile member 100, and the mounting shell 1 can be firmly connected to the mounting wall 110. Therefore, during the installation and use of the transmission mechanism of this embodiment, there is no need to perform additional processing on the profile member 100 to form a larger transmission mechanism installation space, thereby ensuring the inherent strength of the profile and reducing the installation difficulty and processing cost. In addition, since the transmission mechanism of this embodiment cooperates with the output end of the handle 150 through the transmission rack 32 provided on the movable part 3, there is no need to additionally set up other gear rack structures inside the transmission mechanism. Under the premise of ensuring the driving effect of the handle 150 on the transmission mechanism, the number of internal accessories of the transmission mechanism is effectively reduced, and it is convenient to reduce the assembly gap between the accessories inside the transmission mechanism. In some specific embodiments, such as Figure 7 As shown, the limiting edges 12 on the two side walls of the sliding groove 11 are respectively extended in the direction approaching the other side wall.

[0049] It is understandable that, through the above-mentioned structural setting, a reliable limiting structure can be formed on the mounting shell 1, and the movable part 3 is clamped between the limiting edge 12 and the bottom wall of the sliding groove 11, which can facilitate reducing the overall height of the mounting shell 1 and the movable part 3 after matching.

[0050] Of course, in other embodiments of the present invention, the limiting edges 12 on the two side walls of the sliding groove 11 can be extended in a direction away from the other side wall. In this case, the movable part 3 is arranged on the mounting shell 1, and the clamping strip 31 on the movable part 3 can also abut against the bottom wall of the limiting edge 12, so that the mounting shell 1 can limit the movable part 3 in the vertical direction. The specific structure of the limiting edge 12 on the mounting shell 1, the specific structure of the clamping strip 31 on the movable part 3, and the limiting cooperation between the limiting edge 12 and the clamping strip 31 can be determined according to actual needs, and are not specifically limited in other embodiments of the present invention.

[0051] In some embodiments, Figure 1 and Figure 2 As shown, the transmission mechanism further includes a connecting assembly 5 , a connecting portion 33 is provided on the movable member 3 , each connecting portion 33 is sleeved on a connecting assembly 5 , and the connecting assembly 5 can be used to connect with a connecting portion 33 and a transmission member 4 .

[0052] It can be understood that the arrangement of the connecting assembly 5 can facilitate the connection between the movable member 3 and the transmission member 4 having different structures, so that the transmission mechanism has a higher applicability. In addition, the connecting portion 33 sleeved on the connecting assembly 5 can reduce the possibility of relative displacement between the movable member 3 and the connecting assembly 5 in the vertical direction, making the connection relationship between the movable member 3, the connecting assembly 5 and the transmission member 4 more stable and reliable.

[0053] The mounting shell 1, the movable part 3 and the locking assembly do not need to occupy the space of the mounting groove 120, so that the transmission part 4 can be directly matched in the mounting groove 120, and there is no need to cut the transmission part 4 and separate the two ends connected with the movable part 3, which can improve the installation efficiency of the transmission mechanism on the profile member 100. Of course, in the actual application process, the transmission mechanism of this embodiment can use one transmission part 4 according to actual needs, or multiple transmission parts 4 can be used. In addition, in other embodiments of the present invention, the mounting shell 1, the movable part 3 and the transmission part 4 can also be directly arranged on the surface of the profile member 100, and the installation position of the mounting shell 1 and the movable part 3 on the profile member 100 is not limited to the mounting groove 120 described in this embodiment. For example, when the mounting shell 1 and the movable part 3 are directly installed on the flat surface of the profile member 100, the transmission part 4 can also be slidably connected to the boss set on the profile member 100. Specifically, the mounting groove 120 has two side edges 130, and the top wall of each side edge 130 is provided with a flange 140 extending toward the other side edge 130, so that the transmission member 4 can be slidably engaged in the mounting groove 120. Of course, in other embodiments of the present invention, the specific structure of the mounting groove 120 is not limited to the above description and no specific limitation is required.

[0054] Optionally, in the embodiment, the profile member 100 is provided with a mounting groove 120, and the transmission member 4 can be slidably engaged in the mounting groove 120, so that the transmission member 4 does not have a relative displacement in the vertical direction relative to the mounting groove 120. Of course, in other embodiments of the present invention, the transmission member 4 can also cooperate with the profile member 100 through other structures, which need not be specifically limited here.

[0055] In some embodiments, Figure 3 and Figure 6 As shown, the connection assembly 5 includes a fastener 51, a clamping assembly 52 and a first fixing member 53. The fastener 51 can be used to be slidably clamped in the connection groove 41 of the transmission member 4 along the length direction. The clamping assembly 52 can be used to be arranged on the top wall of the transmission member 4, and the clamping assembly 52 can cooperate with the fastener 51 and clamp the transmission member 4. The first fixing member 53 is penetrated in the connection portion 33, the clamping assembly 52 and the fastener 51 and connected to the fastener 51.

[0056] It can be understood that the fastener 51 is clamped in the connection groove 41, and the first fixing member 53 is arranged in the connection part 33, the clamping assembly 52, and the fastener 51 and connected to the fastener 51, so that the first fixing member 53 can simultaneously limit the displacement of the connection part 33, the clamping assembly 52 and the fastener 51 in the horizontal direction and the vertical direction, ensuring the stable connection of the connection part 33, the clamping assembly 52 and the fastener 51. At the same time, the clamping assembly 52 can cooperate with the fastener 51 and clamp the transmission member 4, and the first fixing member 53 arranged in the clamping assembly 52 and the fastener 51 can also apply a fastening force in the vertical direction to the clamping assembly 52 and the fastener 51, thereby ensuring that the clamping assembly 52 can clamp the transmission member 4 firmly with the fastener 51, so that the connection assembly 5 can be firmly connected with the transmission member 4. Therefore, the connection assembly 5 of this embodiment can firmly connect the connection part 33 and the transmission member 4, thereby improving the transmission reliability of the transmission mechanism.

[0057] It should be noted that, in this embodiment, since the transmission member 4 is provided with a connection groove 41 arranged along the length direction of the transmission member 4, the spacing between the movable member 3 and the bottom wall of the connection groove 41 is large, so that the connection assembly 5 can have a large installation space in the vertical direction, so that the structure of the connection assembly 5 of this embodiment can only firmly clamp the transmission member 4 and the movable member 3 in the vertical direction. Since the connection assembly 5 does not need to occupy the position space of the transmission member 4 in the horizontal direction, the transmission member 4 can be clamped in the profile member 100 and connected to the movable member 3 through the connection assembly 5 at different positions at both ends, that is, the transmission member 4 of this embodiment can be assembled without cutting, thereby improving the applicability of the transmission mechanism. Of course, the transmission member 4 with the structure of this embodiment can also be cut into two sections or directly use two sections of the transmission member 4 to connect with the two ends of the movable member 3 respectively. Whether the transmission member 4 is cut or not can be determined according to actual needs.

[0058] It should be supplemented that, in the present embodiment, the transmission member 4 is slidably engaged in the profile member 100, the fastener 51 is engaged in the connection groove 41, the profile member 100 is provided with a mounting groove 120, and the two side walls of the connection groove 41 are respectively provided with an extension edge 42 arranged toward the other side wall, and the two sides of the transmission member 4 are respectively provided with a first engaging block 43 engaged in the mounting groove 120. Through the above structure, the transmission member 4 can be slidably engaged in the profile member 100, and the fastener 51 can be engaged in the connection groove 41. Of course, in other embodiments of the present invention, the connection relationship between the transmission member 4 and the profile member 100 and the fastener 51 and the transmission member 4 can also be achieved through other engaging structures, without specific limitation.

[0059] For example, the first fixing member 53 can be configured as a screw or a bolt.

[0060] Alternatively, if Figure 3 and Figure 6 As shown, there are multiple first fixing members 53 , and the multiple first fixing members 53 are arranged at intervals along the length direction of the movable member 3 . The arrangement of the multiple first fixing members 53 can improve the connection stability between the connecting assembly 5 and the transmission member 4 .

[0061] In some optional embodiments, such as Figure 3 and Figure 6 As shown, a limit strip 511 is respectively provided at both ends of the fastener 51, and each limit strip 511 is extended in a direction away from the other limit strip 511 and in a direction away from the transmission member 4. It can be understood that, through the above-mentioned structural setting, it is convenient to install the fastener 51 and accurately penetrate into the connecting groove 41, and it is also convenient to position the connecting assembly 5 on the connecting groove 41.

[0062] In some specific embodiments, Figure 3 and Figure 6 As shown, the clamping assembly 52 includes a clamping member 521 and a first connecting member 522. The clamping member 521 can be arranged on the transmission member 4, and a recessed portion 5211 is arranged on the peripheral wall of the clamping member 521. The first connecting member 522 is arranged on the clamping member 521, and a matching portion 5221 is provided on the first connecting member 522 to be clamped in the recessed portion 5211.

[0063] It is understandable that, through the above-mentioned structural arrangement, it is possible to facilitate the installation of the clamping assembly 52 on the transmission member 4, and the cooperation between the recessed portion 5211 and the matching portion 5221 can reduce the possibility of relative displacement between the clamping member 521 and the first connecting member 522 in the horizontal direction, thereby improving the connection stability between the clamping member 521 and the first connecting member 522. Of course, in some embodiments, the clamping member 521 and the first connecting member 522 can also be integrally arranged on the movable member 3, which is not specifically limited here.

[0064] In some optional embodiments, such as Figure 3 and Figure 6 As shown, the pressing member 521 is provided with a matching through hole 5212, and the bottom wall of the first connecting member 522 is provided with a matching protrusion 5222 that penetrates the matching through hole 5212. It can be understood that the connection relationship between the pressing member 521 and the fastener 51 can be further strengthened through the above structural arrangement.

[0065] In some optional embodiments, such as Figure 3 and Figure 6As shown, the pressing member 521 is provided with a connecting hole 5213, each connecting hole 5213 is provided corresponding to a first fixing member 53, and the fastener 51 is provided with an extending protrusion 512 extending in a direction close to the pressing member 521, each extending protrusion 512 is provided corresponding to a connecting hole 5213, the extending protrusion 512 extends into the connecting hole 5213, and the first fixing member 53 is threadedly connected with the extending protrusion 512. It can be understood that the connection relationship between the pressing member 521 and the fastener 51 can be further strengthened through the above-mentioned structural arrangement.

[0066] In some embodiments, Figure 9-13 As shown, the connecting assembly 5 includes a second connecting member 54 and a second fixing member 55. A fastening protrusion 543 is provided on the bottom wall of the second connecting member 54, and the fastening protrusion 543 can be used to penetrate the matching hole 45 on the transmission member 4. The second fixing member 55 is penetrated in the connecting portion 33 and connected to the second connecting member 54.

[0067] It can be understood that the second connecting member 54 is firmly connected to the connecting portion 33 through the second fixing member 55, and the connecting portion 33 cannot be relatively displaced with the mounting shell 1 in the vertical direction, so that the second connecting member 54 cannot be relatively displaced with the connecting portion 33 in the vertical direction, and the mounting shell 1 is firmly connected to the mounting wall 110 of the profile member 100, so that after the transmission member 4 is connected to the movable member 3, the second connecting member 54 and the transmission member 4 cannot be relatively displaced with the profile member 100 in the vertical direction. At this time, since the fastening protrusion 543 can be inserted into the matching hole 45, the connection between the second connecting member 54 and the transmission member 4 is realized, that is, the stable connection between the movable member 3 and the transmission member 4 is realized, and the transmission reliability of the transmission mechanism is improved.

[0068] It should be noted that, in the present embodiment, since the connection between the second connecting member 54 and the transmission member 4 is formed by the cooperation between the fastening protrusion 543 and the matching hole 45, during the actual installation process, the transmission member 4 can also determine whether it needs to be cut off according to actual needs. Even if there is a small gap between the top wall of the transmission member 4 and the connecting portion 33, a stable connection between the transmission member 4 and the movable member 3 can be achieved without additionally cutting the transmission member 4. That is, the transmission member 4 of the present embodiment can be assembled without cutting, thereby improving the applicability of the transmission mechanism.

[0069] In some optional embodiments, such as Figure 9-12As shown, the bottom wall of the second connecting member 54 can be used to abut against the top wall of the transmission member 4, and a fastening protrusion 543 is provided on the bottom wall of the second connecting member 54. It can be understood that, through the above-mentioned structural arrangement, the second connecting member 54 can be arranged between the connecting portion 33 and the transmission member 4, which can not only facilitate the installation of the connecting assembly 5 and reduce the overall height of the transmission mechanism, but also further improve the connection stability between the second connecting member 54 and the connecting portion 33. Of course, in other embodiments of the present invention, such as Fig.13 As shown, the second connecting member 54 can also be spaced apart from the connecting portion 33 so that the transmission member 4 can be disposed between the second connecting member 54 and the connecting portion 33 , thereby improving the connection stability of the transmission member 4 between the connecting assembly 5 and the connecting portion 33 .

[0070] In some optional embodiments, the second connecting member 54 and the connecting portion 33 are integrally formed. It is understandable that the second connecting member 54 and the connecting portion 33 are provided as an integrally formed member to strengthen the connection stability when the connecting portion 33 and the second connecting member 54 are connected to the transmission member 4, thereby improving the transmission reliability of the transmission mechanism. Of course, in other embodiments of the present invention, the second connecting member 54 and the connecting portion 33 can also be provided as independent structures, which can facilitate the installation of the transmission mechanism.

[0071] For example, the second fixing member 55 can be configured as a screw or a bolt.

[0072] Alternatively, if Fig.10 and Fig.12 As shown, there are multiple second fixing members 55 , and the multiple second fixing members 55 are arranged at intervals along the length direction of the movable member 3 . The arrangement of the multiple second fixing members 55 can improve the connection stability between the connecting assembly 5 and the transmission member 4 .

[0073] In some embodiments, the second connecting member 54 further includes a clamping end 541 and a connecting end 542. The clamping end 541 can be slidably clamped in the profile member 100. The connecting end 542 is connected to the clamping end 541, and a fastening protrusion 543 is provided on the connecting end 542.

[0074] It can be understood that the clamping end 541 can be slidably clamped in the profile member 100, and at the same time, the second connecting member 54 is connected to the connecting portion 33 through the second fixing member 55, so that when the transmission mechanism is installed on the profile member 100 as a whole and is not connected to the transmission member 4, it can still be installed on the profile member 100 under the limit of the clamping end 541, thereby avoiding the phenomenon of the transmission mechanism falling off from the profile member 100, which is conducive to the fast and stable connection of the movable member 3 with the transmission member 4. In addition, the connecting end 542 is provided on the transmission member 4 and connected to the transmission member 4. The connecting end 542 can be inserted into the transmission member 4 and connected to the transmission member 4, or the connecting end 542 can be connected to the transmission member 4 through a connecting structure. The connection relationship between the connecting end 542 and the transmission member 4 can be determined according to actual needs and is not specifically limited here.

[0075] It should be noted that, in this embodiment, since the second connecting member 54 includes a clamping end 541, the end faces of the two clamping ends 541 can respectively abut against the end face of a transmission member 4, and are respectively connected to a transmission member 4 through the connecting parts 33 at both ends of the movable member 3 through the connecting assembly 5, the connection stability between the transmission member 4 and the connecting part 33 can be improved. At the same time, considering the cutting process of the transmission member 4 and the connection problem of the transmission member 4 and the movable member 3, according to the structural setting of the connecting assembly 5 of this embodiment, when the structure of the transmission member 4 is not convenient for stable connection with the movable member 3, in actual application, two transmission members 4 can be prepared at the same time, and one transmission member 4 can be cut into two transmission members 4, and the stable connection between the movable member 3 and the transmission member 4 can be ensured, thereby improving the transmission reliability of the transmission mechanism.

[0076] More specifically, in this embodiment, the transmission member 4 includes a transmission body 44 and second clamping blocks 441 provided on both sides of the transmission body 44, so that the transmission member 4 can be slidably clamped in the profile member 100. Of course, in other embodiments of the present invention, the transmission member 4 can be clamped in the profile member 100 through other structures.

[0077] In some specific embodiments, one end of the clamping end 541 of each second connecting member 54 can be used to abut against an end face of a transmission member 4. It can be understood that since the clamping end 541 can be connected to the end face of the transmission member 4, the possibility of relative rotation between the clamping end 541 and the transmission member 4 is effectively reduced, thereby improving the connection stability between the second connecting member 54 and the transmission member 4.

[0078] In some optional embodiments, the clamping end 541 is connected to the connecting portion 33 via the second connecting member 54, which can further improve the connection stability between the movable member 3 and the transmission member 4 and improve the stability of the transmission mechanism when driving the transmission member 4 to move.

[0079] In some embodiments, Figure 3 , Figure 6 , Fig.10 and Fig.12 As shown, the connecting portion 33 forms a limiting groove 331, the groove opening of the limiting groove 331 is opened toward the transmission member 4, a plurality of first limiting protrusions 332 are provided on the limiting groove 331, and a plurality of second limiting protrusions 56 are provided on the connecting component 5. When the connecting portion 33 is sleeved on the connecting component 5, a second limiting protrusion 56 is fitted between two adjacent first limiting protrusions 332, and / or a first limiting protrusion 332 is fitted between two adjacent second limiting protrusions 56.

[0080] It can be understood that the connecting component 5 is passed through the connecting part 33 and the transmission part 4, so that the connecting component 5 can limit the relative displacement of the movable part 3 and the transmission part 4 in the vertical direction. At the same time, the cooperation between the first limiting protrusion 332 and the second limiting protrusion 56 can limit the connection part 33 and the connecting component 5 in the length direction of the mounting groove 120, so that the connecting component 5 can reliably connect the movable part 3 and the transmission part 4, effectively reducing the possibility of relative displacement among the movable part 3, the connecting component 5 and the transmission part 4, thereby improving the movement accuracy of the transmission mechanism.

[0081] In some embodiments, Figure 6 As shown, a connecting hole 333 is provided on the connecting portion 33 , and the connecting component 5 is passed through the connecting hole 333 . The connecting component 5 has a limiting end, and the limiting end can abut against the top wall of the connecting portion 33 .

[0082] It can be understood that the arrangement of the connection hole 333 and the limiting end can facilitate the connection assembly 5 to firmly lock the connection portion 33 on the transmission member 4, thereby ensuring the stability of the connection between the movable member 3 and the transmission member 4.

[0083] Optionally, a chamfered surface or a rounded surface can be opened between the connecting hole 333 and the top wall of the connecting part 33 to improve the aesthetics of the connecting part 33 and facilitate the cooperation between the connecting part 33 and the connecting component 5. The specific structure of the connecting hole 333 can be determined according to actual needs and no specific limitation is required here.

[0084] In some optional embodiments, the connecting hole 333 can be set as a countersunk hole. The setting of the countersunk hole can facilitate the cooperation between the connecting component 5 and the connecting hole 333, increase the contact area between the connecting component 5 and the connecting hole 333, and also facilitate setting the end of the connecting component 5 within the top wall of the connecting part 33 to avoid the end of the connecting component 5 protruding from the connecting part 33, thereby further improving the connection stability between the movable part 3 and the transmission part 4.

[0085] Optionally, the inner wall of the countersunk section of the countersunk hole can be set to a structure such as a plane or a plane concave platform. The specific structure of the countersunk hole can be determined according to actual needs and does not need to be specifically limited here.

[0086] In some embodiments, the connecting hole 333 is a waist-shaped hole, and the length direction of the waist-shaped hole forms an angle with the length direction of the movable member 3 .

[0087] It can be understood that, since the connecting hole 333 is set as a waist-shaped hole, the connecting component 5 can be displaced along the length direction of the waist-shaped hole, that is, relative displacement can occur between the connecting component 5 and the connecting portion 33, and at the same time, after the connecting component 5 is connected to the transmission member 4, the position of the connecting component 5 relative to the profile member 100 is fixed, that is, the position of the mounting shell 1 and the movable member 3 relative to the profile member 100 can be adjusted according to actual conditions. For example, when the side walls of the mounting shell 1 and the movable member 3 are not abutted against the mounting wall 110 of the profile member 100, the connecting component 5 is not abutted at the extreme position of the waist-shaped hole. At this time, the mounting shell 1 can be driven to move relative to the profile member 100 by moving the movable member 3. When the mounting shell 1 abuts against the mounting wall 110, the connecting component 5 and the transmission member 4 are stabilized. The fixed connection can ensure that the movable part 3 and the transmission part 4 are firmly connected, and ensure that the mounting shell 1 abuts against the mounting wall 110. That is to say, since the connecting hole 333 of the present embodiment is a waist-shaped hole, the position of the mounting shell 1 on the profile member 100 can be adjusted according to actual needs. For example, when the transmission member 4 is installed at a preset position on the profile member 100, if the central axis of the movable part 3 is the same as that of the transmission member 4, there is a gap between the mounting shell 1 and the mounting wall 110. At this time, since the connection position of the movable part 3 and the transmission member 4 is not fixed, the movable part 3 can move toward the direction close to the mounting wall 110 under the action of the waist-shaped hole, and make the mounting shell 1 abut against the mounting wall 110, thereby effectively improving the adaptability of the transmission mechanism and being applicable to a variety of different profile members 100.

[0088] In some optional embodiments, the length direction of the waist-shaped hole is perpendicular to the length direction of the movable part 3. At this time, when the mounting shell 1 moves a preset length in the length direction perpendicular to the movable part 3, the distance between the side wall of the mounting shell 1 and the mounting wall 110 changes the most, which can facilitate the position adjustment of the mounting shell 1 on the profile part 100, so that the mounting shell 1 can be quickly connected to the mounting wall 110, thereby improving the installation efficiency of the transmission mechanism.

[0089] In some embodiments, Figure 2 and Figure 7As shown, the mounting shell 1 includes a first shell 13 and a second shell 14. The first shell 13 is arranged on the profile 100, and the side wall of the first shell 13 abuts against the mounting wall 110. A connecting protrusion 131 is arranged on the side of the first shell 13 away from the mounting wall 110. The second shell 14 is arranged on the mounting groove 120, and the second shell 14 is sleeved on the connecting protrusion 131. Two limiting edges 12 are respectively arranged on the first shell 13 and the second shell 14.

[0090] It is understandable that the arrangement of the first shell 13 and the second shell 14 can not only facilitate the installation of the mounting shell 1 on the profile 100, but also facilitate the processing of the mounting shell 1, thereby reducing the processing difficulty of the mounting shell 1. At the same time, the arrangement of the connecting protrusion 131 can limit the second shell 14, so that the second shell 14 can be stably and reliably connected to the first shell 13.

[0091] In some optional embodiments, such as Figure 7 As shown, a locking groove 132 is provided on the bottom wall of the first shell 13, and a locking hole 141 is provided on the second shell 14. The locking assembly is inserted into the locking hole 141, the locking groove 132, and the profile 100 and is connected to the handle 150. The locking assembly and the profile 100 can simultaneously limit the first shell 13 and the second shell 14, so that the first shell 13 and the second shell 14 are firmly arranged on the profile 100 in the vertical direction.

[0092] In some embodiments, Figure 2 and Figure 7 As shown, an elastic member 6 is provided on the inner wall of the sliding groove 11, and an escape groove 34 is provided on the side wall of the movable member 3. The elastic member 6 is in a compressed state when it abuts against the side wall of the movable member 3, and is in a relaxed state when it abuts in the escape groove 34.

[0093] It is understandable that when the elastic member 6 abuts against the side wall of the movable member 3, the elastic member 6 can apply elastic force to the movable member 3, and when the elastic member 6 abuts against the avoidance groove 34, the elastic force of the elastic member 6 on the movable member 3 disappears, so that the operator can have two different force sensations when driving the movable member 3 to move through the handle 150, so that the operator can obtain the position information of the movable member 3 relative to the profile member 100 according to the feeling of driving the movable member 3 to move, so as to facilitate the operator to use the transmission mechanism. Exemplarily, when the elastic member 6 abuts against the avoidance groove 34, the movable member 3 can be set to the initial position, so that the elastic member 6 is used as a positioning structure to improve the user experience of the operator.

[0094] In some specific embodiments, Figure 2 and Figure 7As shown, the elastic member 6 includes two elastic parts 61 and a rigid part 62, the two elastic parts 61 are arranged at intervals along the length direction of the transmission member 4, one end of the two elastic parts 61 abuts against the inner wall of the mounting shell 1 respectively, and the other end is connected to the rigid part 62. It can be understood that the arrangement of the rigid part 62 can facilitate the elastic member 6 to abut against the avoidance groove 34 or the movable member 3.

[0095] In some embodiments, Figure 7 As shown, a matching groove 111 is formed on the bottom wall of the sliding groove 11 , and the matching groove 111 can be used to support the output end of the handle 150 .

[0096] It is understandable that the arrangement of the matching groove 111 can make the driving end of the handle 150 not need to be suspended in the air, and can avoid the bending of the driving end of the handle 150, so that the transmission mechanism can better protect the handle 150 and extend the service life of the handle 150. In addition, the driving end of the handle 150 is arranged in the matching groove 111, which can further reduce the distance between the driving end of the handle 150 and the movable part 3, thereby reducing the height and space occupied by the transmission mechanism, thereby improving the applicability of the transmission mechanism.

[0097] Alternatively, if Figure 7 As shown, the driving end of the handle 150 includes an outer tooth section and a rotating section, and the mating groove 111 includes a first mating section 1111 and a second mating section 1112. The outer tooth section is mated in the first mating section 1111, and the rotating section is mated in the second mating section 1112. Through the above-mentioned structural setting, the mating groove 111 can provide better protection for the driving end of the handle 150.

[0098] In some embodiments, Figure 1 and Figure 2 As shown, the locking assembly includes a plurality of locking members 2 , and at least one locking member 2 is respectively disposed on both sides of the matching groove 111 .

[0099] It is understandable that at least one locking member 2 is provided on both sides of the mating groove 111, which can reduce the torque applied by the handle 150 to the mounting wall 110 when the handle 150 rotates clockwise or counterclockwise, thereby further improving the connection stability between the transmission mechanism, the handle 150 and the profile member 100.

[0100] Embodiment 1:

[0101] Reference below Figure 1-Figure 7 A transmission mechanism according to a specific embodiment of the present invention is described.

[0102] The transmission mechanism of this embodiment includes a mounting shell 1 , a locking assembly, a movable part 3 , a connecting assembly 5 and an elastic part 6 .

[0105] The movable member 3 is inserted into the sliding groove 11. The two side walls of the movable member 3 are provided with a clamping strip 31 that abuts against the limiting edge 12. The bottom wall of the movable member 3 is provided with a transmission rack 32, which can mesh with the output end of the handle 150. A connecting portion 33 is provided at each end of the movable member 3, and the connecting portion 33 is sleeved on the connecting assembly 5. The connecting portion 33 forms a limiting groove 331, and the notch of the limiting groove 331 is opened toward the transmission member 4. The limiting groove 331 is provided with a plurality of first limiting protrusions 332 arranged at intervals. The connecting portion 33 is provided with a connecting hole 333, and the connecting hole 333 can be set as a waist-shaped hole, and the length direction of the waist-shaped hole has an angle with the length direction of the movable member 3. The connecting portion 33 can be used to connect with the transmission member 4.

[0106] Each connecting assembly 5 is connected to a connecting portion 33 and a transmission member 4, respectively. The connecting assembly 5 is provided with a plurality of second limiting protrusions 56 arranged at intervals. When the connecting portion 33 is sleeved on the connecting assembly 5, a second limiting protrusion 56 is matched between two adjacent first limiting protrusions 332, and / or a first limiting protrusion 332 is matched between two adjacent second limiting protrusions 56. The connecting assembly 5 is arranged in the connecting hole 333, and the connecting assembly 5 has a limiting end, which can abut against the top wall of the connecting portion 33. The connecting assembly 5 includes a fastener 51, a clamping assembly 52 and a first fixing member 53. The fastener 51 can be used to be slidably clamped in the connecting groove 41 of the transmission member 4 along the length direction. The clamping assembly 52 can be used to be arranged on the top wall of the transmission member 4, and the clamping assembly 52 can cooperate with the fastener 51 and clamp the transmission member 4. The first fixing member 53 is arranged in the connecting portion 33, the clamping assembly 52 and the fastener 51 and is connected to the fastener 51. The clamping assembly 52 includes a clamping member 521 and a first connecting member 522. The clamping member 521 is provided on the transmission member 4. A recessed portion 5211 is provided on the peripheral wall of the clamping member 521. The first connecting member 522 is provided on the clamping member 521. A matching portion 5221 engaged in the recessed portion 5211 is provided on the first connecting member 522. A matching through hole 5212 is provided on the clamping member 521. A matching protrusion 5222 penetrating the matching through hole 5212 is provided on the bottom wall of the first connecting member 522. The pressing member 521 is provided with a connecting hole 5213, each connecting hole 5213 is provided corresponding to a first fixing member 53, and the fastener 51 is provided with an extending protrusion 512 extending in a direction close to the pressing member 521, each extending protrusion 512 is provided corresponding to a connecting hole 5213, the extending protrusion 512 extends into the connecting hole 5213, and the first fixing member 53 is threadedly connected with the extending protrusion 512.

The two elastic parts 61 are arranged at intervals along the length direction of the transmission member 4, and one end of the two elastic parts 61 abuts against the escape groove 34 respectively, and the other end is connected to the rigid part 62.

[0108] It should be noted that, in this embodiment, since the transmission member 4 is provided with a connection groove 41 arranged along the length direction of the transmission member 4, the spacing between the movable member 3 and the bottom wall of the connection groove 41 is large, so that the connection component 5 can have a large installation space in the vertical direction, so that the structure of the connection component 5 of this embodiment can only firmly clamp the transmission member 4 and the movable member 3 in the vertical direction. Since the connection component 5 does not need to occupy the position space of the transmission member 4 in the horizontal direction, the transmission member 4 can be inserted into the installation groove 120 and connected to the movable member 3 at different positions at both ends through the connection component 5, that is, the transmission member 4 of this embodiment can be assembled without cutting, thereby improving the applicability of the transmission mechanism. Of course, the transmission member 4 with the structure of this embodiment can also be cut into two sections or directly use two sections of the transmission member 4 to connect with the two ends of the movable member 3 respectively. Whether the transmission member 4 is cut or not can be determined according to actual needs.

[0109] Embodiment 2:

[0110] The transmission mechanism of this embodiment is substantially the same in structure as that of embodiment 1, and the difference between the two is the structure of the transmission member 4 and the connecting assembly 5. Only the difference between the two is described here, and the structures of this embodiment that are the same as those of embodiment 1 are not repeated here.

[0111] like Figure 8-Figure 12 As shown, the connecting assembly 5 includes a second connecting member 54 and a second fixing member 55. The bottom wall of the second connecting member 54 can be used to abut against the top wall of the transmission member 4. The bottom wall of the second connecting member 54 is provided with a fastening protrusion 543, and the fastening protrusion 543 can be used to penetrate the matching hole 45 on the transmission member 4. The second fixing member 55 is penetrated in the connecting portion 33 and connected to the second connecting member 54.

[0112] In this embodiment, since the connection between the second connecting member 54 and the transmission member 4 is formed by the cooperation between the fastening protrusion 543 and the matching hole 45, during the actual installation process, the transmission member 4 can also determine whether it needs to be cut off according to actual needs. Even if there is a small gap between the top wall of the transmission member 4 and the connecting portion 33, a stable connection between the transmission member 4 and the movable member 3 can be achieved without additionally cutting the transmission member 4. That is, the transmission member 4 of this embodiment can be assembled without cutting, thereby improving the applicability of the transmission mechanism.

[0113] Embodiment 3:

[0114] The transmission mechanism of this embodiment is substantially the same in structure as that of embodiment 2, and the difference between the two is the structure of the connecting assembly 5. Only the difference between the two is described here, and the structures of this embodiment that are the same as those of embodiment 2 are not repeated here.

[0115] like Figure 8-Figure 12As shown, the second connecting member 54 further includes a clamping end 541 and a connecting end 542. One end of the clamping end 541 of each second connecting member 54 can be used to abut against the end surface of a transmission member 4, and the clamping end 541 can be slidably clamped in the profile member 100. The connecting end 542 is connected to the clamping end 541, and the bottom wall of the connecting end 542 can be used to abut against the top wall of a transmission member 4, and the fastening protrusion 543 is provided on the bottom wall of the connecting end 542.

[0116] It should be noted that, in this embodiment, since the second connecting member 54 includes a clamping end 541, and the end faces of the two clamping ends 541 can respectively abut against the end face of one transmission member 4, the transmission mechanism of this embodiment needs to cooperate with two transmission members 4 in actual application, and is respectively connected to one transmission member 4 through the connecting parts 33 at both ends of the movable member 3 through the connecting assembly 5, which can improve the connection stability between the transmission member 4 and the connecting part 33. At the same time, considering the cutting and processing of the transmission member 4 and the connection problem of the transmission member 4 and the movable member 3, according to the structural setting of the connecting assembly 5 of this embodiment, when the structure of the transmission member 4 is not convenient for stable connection with the movable member 3, the transmission member 4 can be cut into two to ensure the stable connection between the movable member 3 and the transmission member 4, thereby improving the transmission reliability of the transmission mechanism.

[0117] Embodiment 4:

[0118] The transmission mechanism of this embodiment is substantially the same in structure as that of embodiment 2, and the difference between the two is the structure of the connecting assembly 5. Only the difference between the two is described here, and the structures of this embodiment that are the same as those of embodiment 2 are not repeated here.

[0119] like Fig.13 As shown, the second connecting member 54 can also be spaced apart from the connecting portion 33 so that the transmission member 4 can be disposed between the second connecting member 54 and the connecting portion 33 , which can improve the connection stability of the transmission member 4 between the connecting assembly 5 and the connecting portion 33 .

[0120] A transmission device includes a profile 100, the transmission mechanism described above, and a transmission member 4. The profile 100 is provided with a mounting wall 110 and a mounting groove 120.
