[0043] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of this 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 present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art 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.

[0045] Example 1

[0046] See also Figures 1-9 This embodiment discloses a side handle, including a handle 1, a base 2, a transmission shaft 4 and a transmission assembly 3 capable of vertically transmitting power.

[0047] Base 2 is fixed to the side of the frame profile; handle 1 is located on the front of base 2. This front can be understood as the side facing the user, most often facing indoors; however, when the handle is outdoors, this front can be understood as the side facing outdoors. Transmission assembly 3 is located within base 2; the power input end of transmission assembly 3 is connected to handle 1, and the power output end of transmission assembly 3 is connected to transmission shaft 4. During operation, the direction of rotation of handle 1 is perpendicular to the direction of rotation of transmission shaft 4.

[0048] In this embodiment, the transmission assembly 3 includes a driving gear 301, a driven gear 303, and a transmission bar 302 extending in the vertical direction. The driving gear 301 constitutes the power input end, and the driven gear 303 constitutes the power output end. The driving gear 301 is connected to the handle 1, and the driven gear 303 is connected to the transmission shaft 4. The axes of the driving gear 301 and the driven gear 303 are perpendicular to each other. The transmission bar 302 is arranged between the driving gear 301 and the driven gear 303, and the first transmission teeth 3021 and the second transmission teeth 3022 of the transmission bar 302 are matched with the driving gear 301, and the second transmission teeth 3022 are matched with the driven gear 303. In this embodiment, by arranging the driving gear 301, the driven gear 303, and the transmission bar 302 in the limited inner cavity of the base 2, power transmission can be achieved, and the structure is simple and reliable. In addition, while achieving vertical power transmission, the rotation control stroke of the handle 1 can also be adjusted. Specifically, by changing the transmission ratio between the driving gear 301 and the first transmission teeth 3021, or the transmission ratio between the driven gear 303 and the second transmission teeth 3022, the rotation angle of the handle 1 and the movement stroke of the transmission components in the transmission shaft 4 and the transmission 5 can be adjusted. For example, by adjusting the transmission ratio, when the handle 1 is rotated 90 degrees, the driven gear 303 can rotate 90 degrees, 180 degrees, or other angles.

[0049] See also Figure 1-Figure 2 The figure shows a front view and a top view of a specific embodiment of the side handle of this embodiment applied to a window sash frame 10. As can be seen from the figure, the front width of the window sash frame 10 is relatively narrow, so the handle cannot be installed. However, the side handle of this embodiment is installed on the side of the window sash frame 10. The left side of the window sash frame 10 in the figure is the window fixing frame 11.

[0050] In this embodiment, the base 2 is provided with a vertically extending slot 2012, into which the transmission bar 302 is partially embedded; the upper and lower ends of the slot 2012 form travel limits for the transmission bar 302. Specifically, the horizontal cross-section of the transmission bar 302 in this embodiment is generally Z-shaped, with the first transmission teeth 3021 and the second transmission teeth 3022 located on either side of the transmission bar 302.

[0051] The driving gear 301 is provided with a connecting portion 3011 extending along its axis. The handle 1 is provided with a connecting cavity 101 whose inner contour matches that of the connecting portion 3011. The connecting portion 3011 passes through the base 2 and is then embedded in the connecting cavity 101. To improve the integrity between the handle 1 and the driving gear 301, the connecting portion 3011 is square in this embodiment. However, other shapes are possible, with non-circular structures being preferred to prevent slippage between the two.

[0052] The driving gear 301 is provided with a connecting hole 3013, which is coaxial with the driving gear 301. The handle 1 and the driving gear 301 are fixedly connected via the connecting hole 3013 and the locking structure. The connecting hole 3013 allows a locking structure such as a screw, bolt, or other fastener to be passed through the connecting hole 3013 and locked to the handle 1.

[0053] As another embodiment, the handle 1 and the driving gear 301 can be configured as an integrated structure.

[0054] The driving gear 301 is sleeved with a first sleeve 6 and a second sleeve 7. The first sleeve 6 is positioned outside the second sleeve 7, leaving a clearance between the first sleeve 6 and the second sleeve 7 for mating with the base 2. To facilitate the passage of the connecting portion 3011, a corresponding through-hole 2011 is provided in the base 2. The edge of the through-hole 2011 fits into the clearance between the first sleeve 6 and the second sleeve 7. The arrangement of the first sleeve 6 and the second sleeve 7 improves the sealing performance of the through-hole 2011 and ensures more stable and reliable rotation of the handle 1 and the driving gear 301.

[0055] In this embodiment, at least one positioning assembly is provided in the base 2, and each positioning assembly is distributed along the circumference of the driving gear 301; the positioning assembly includes a positioning member 8 and an elastic element 9; the second shaft sleeve 7 is provided with a receiving groove 701 for accommodating the positioning assembly, and the positioning member 8 and the elastic element 9 are both located in the receiving groove 701. Under the elastic force of the elastic element 9, the positioning member 8 is pressed against the end of the receiving groove 701 and partially protrudes; a plurality of positioning grooves 3012 distributed at equal intervals are provided on the circumference of the driving gear 301, and the part of the positioning member 8 protruding from the receiving groove 701 forms a mating positioning with the positioning groove 3012.

[0056] In this embodiment, two positioning components are provided in combination with the structural layout of the driven gear 303 and the transmission bar 302. Of course, the number of positioning components can be flexibly adjusted and there is no limit to the number.

[0057] By setting the positioning assembly, when the handle 1 rotates, the positioning groove 3012 of the driving gear 301 forms a positioning match with the positioning member 8, which makes the rotation feel better and has a positioning effect.

[0058] In this embodiment, the positioning member 8 is a ball, and the elastic element 9 is a spring.

[0059] Furthermore, in this embodiment, a mating portion 3031 is provided on one side of the driven gear 303. The end of the mating portion 3031 is provided with a mating hole, into which the transmission shaft 4 is connected. Specifically, in this embodiment, the transmission shaft 4 is a square shaft, and the mating hole is a square hole. During installation, the driven gear 303 drives the transmission shaft 4 to rotate synchronously by inserting the transmission shaft 4 into the mating hole.

[0060] As another embodiment, the driven gear 303 and the transmission shaft 4 may be provided as an integrated structure.

[0061] The base 2 of this embodiment includes a base body 201 and a bottom cover 202. The inner cavity of the base body 201 is opened, and the bottom cover 202 is detachably connected to the base body 201 and is located at the opening of the base body 201. Specifically in this embodiment, the bottom cover 202 and the base body 201 can be connected and fixed by multiple screws.

[0062] In order to better allow the driving gear 301, the driven gear 303 and the transmission shaft 4 to cooperate and move in the inner cavity of the base body 201, a groove structure corresponding to each part is provided in the inner cavity of the base body 201. For details, please refer to Figure 8-Figure 9 The mounting groove 2013 that cooperates with the driven gear 303 is divided into two parts, which are located on the base 201 and the bottom cover 202 respectively.

[0063] Example 2

[0064] The difference between this embodiment and embodiment 1 is that:

[0065] The transmission assembly of this embodiment differs from transmission assembly 3 of Example 1. It includes a driving bevel gear and a driven bevel gear. The driving bevel gear is connected to handle 1, and the driven bevel gear is connected to transmission shaft 4. The driving and driven bevel gears mesh with each other, with their axes perpendicular to each other. Compared to Example 1, this embodiment uses bevel gears to achieve vertical power transmission, using fewer parts and a simpler structure.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
