Referring to fig. 1-3 and 7-17, the side surface of the screw fixing portion 121 is provided with an arc surface 1211. The side surface means one side or both sides of the side surface of the screw fixing portion 121 contacting the profile 200. In this embodiment, both sides of the screw fixing portion 121 are provided with arc surfaces 1211.

It should be noted that the screw fixing portion 121 may have an arc 1211 on both sides, or may have an arc 1211 on only one side, and when one side has an arc, the side having an arc is adapted to the direction of rotation of the fixing screw 12 when the fixing screw is screwed.

After the technical scheme is adopted, on one hand, when the screw fixing part 121 and the bottom of the base body 11 clamp the profile 200, the cambered surface 1211 arranged on the side surface of the screw fixing part 121 has radian, so that the resistance when the screw fixing part 121 slides on the profile 200 is reduced, and the installation of the fixing screw 12 is facilitated; on the other hand, because the fixing screw 12 is in threaded connection with the base body 11, and a thread pitch exists, the side surface of the screw fixing portion 121 is provided with the cambered surface 1211, so that the screw fixing portion 121 and the base body 11 can clamp the profile 200 conveniently, for example, because the thickness of the profile 200 is different, the fixing screw 12 is rotated, when the clamping force between the screw fixing portion 121 and the base body 11 is maximum, the screw fixing portion 121 just corresponds to the mounting hole 201, so that the screw fixing portion 121 and the base body 11 cannot clamp the profile 200 well, but the side surface of the screw fixing portion 121 is provided with the cambered surface 1211, so that the screw fixing portion 121 can clamp the profile 200 further easily, and the screw fixing portion 121 and the base body 11 can clamp the profile 200 better.

Furthermore, dividing the handle shaft 30 into three parts, namely the handle mounting part 31, the clamping part 32 and the transmission part 33, greatly simplifies the structure of the handle 100 and reduces some other unnecessary structures. In addition, because the fixing screw 12 is hidden in the section bar 200 and the base body 11, the base body 11 can be hidden in the handle 20, so that the base body 11 can not be seen when the handle 100 is mounted on the section bar 200, the material is saved, the user is prevented from colliding with the base body 11, and the appearance is attractive, exquisite and small, and three benefits are achieved.

Referring to fig. 1-3 and 7-13, the handle 100 further includes a handle limiting unit 40, where the handle limiting unit 40 includes a steel ball 41, a spring 42, a spring mounting hole 43, a limiting pressing piece 44, and a limiting pressing piece clamping portion 45, where the spring mounting hole 43 is formed on the base body 11, the limiting pressing piece clamping portion 45 is formed on the handle mounting portion 31, and the limiting pressing piece 44 is formed with a limiting hole 411 and two or more positioning holes 412, and the limiting hole 411 and the limiting pressing piece clamping portion 45 are mutually clamped to fix the limiting pressing piece 44 at any position on the limiting pressing piece clamping portion 45, i.e. the position of the limiting pressing piece 44 on the handle shaft 30 can be adjusted. The spring 42 is installed in the spring installation hole 43, the steel ball 41 is installed between the spring 42 and the positioning hole 412, the diameter of the steel ball 41 is smaller than or equal to that of the spring installation hole 43 and larger than that of the positioning hole 412, when the handle 20 drives the handle shaft 30 to rotate in the handle installation hole 112, the limiting pressing piece 44 follows the handle shaft 30 to rotate and forces the steel ball 41 to retract into the spring installation hole 43, and when the positions of the steel ball 41 correspond to those of other positioning holes 412, the steel ball 41 is rebounded into the corresponding positioning hole 412.

In this embodiment, the limiting pressing piece 44 is a disc structure, the limiting hole 411 is formed in the middle of the limiting pressing piece 44, the spring mounting hole 43 and the positioning hole 412 are circular holes, the limiting pressing piece clamping portion 45 includes a plurality of clamping grooves 451, the clamping grooves 451 are uniformly distributed on the handle mounting portion 31, the limiting hole 411 can move on the limiting pressing piece clamping portion 45 under the action of external force, and when no external force or the external force is smaller, the limiting pressing piece clamping portion 45 is fixed in the limiting hole 411, i.e. the limiting pressing piece 44 is fixed on the handle shaft 30.

When the handle 100 is installed, the base 10 is firstly installed, the fixing screw 12 is firstly initially installed on the base body 11, then the handle installation part 31 passes through the handle installation hole 112, then the spring 42 is put into the spring installation hole 43, then the limiting pressing piece 44 is installed on the handle installation part 31 of the handle shaft 30 through the mutual clamping between the limiting hole 411 and the limiting pressing piece clamping part 45, meanwhile, the steel balls are put between the spring 42 and the positioning hole 412, the position of the limiting pressing piece 44 is adjusted, the spring 42 is in a compressed state, the handle shaft 30 is fixed on the base body 11 under the interaction between the clamping part 32 and the base body 11 and between the limiting pressing piece 44 and the spring 42 and the base body 11, then the lower ends of the handle shaft 30 and the fixing screw 12 pass through the handle shaft through hole 202 and the installation hole 201, the clamping part 32, the transmission part 33 and the screw fixing part 121 on the handle shaft 30 are positioned in the section bar 200, then the handle shaft 30 is rotated, the positioning hole 412 is rotated to the fixing hole 111, then the corresponding tool is used for rotating the fixing screw 12, the screw fixing part 121 is moved away from the base body 11, and the handle shaft 200 is installed on the base body 11, and the handle shaft 20 is fixed on the base body 20, and the handle body is installed on the base body 11, and the handle shaft 20 is clamped on the base body 20.

After the technical scheme is adopted, the limiting pressing piece 44 is fixed at a proper position on the limiting pressing piece clamping part 45 through the mutual clamping between the limiting hole 411 and the limiting pressing piece clamping part 45, the spring 42 is elastic to the limiting pressing piece 44, when the handle 20 drives the handle shaft 30 to rotate, the limiting pressing piece 44 also rotates along with the handle shaft, but the steel ball 41 and the spring 42 do not rotate, the steel ball 41 leaves the positioning hole 412 and is arranged in the spring mounting hole 43, after the handle 20 rotates for a certain angle, namely, when the position of the steel ball 41 corresponds to the position of another adjacent positioning hole 412, the steel ball 41 is rebounded into the corresponding positioning hole 412, so that the limiting and positioning of the handle are realized, and the hand feeling of a user using the handle is greatly enhanced.

In addition, because of the elastic force of the spring 42, the spring 42 has an acting force on the limit pressing piece 44 in a direction of keeping away from the base body 11, even if the handle 20 mounted on the handle shaft 30 has a trend of keeping away from the base body 11, the interaction between the clamping part 32 and the bottom of the base body 11 prevents the handle shaft 30 from keeping away from the base body 11, so that sliding friction between the handle 20 and the profile 200 is converted into rolling friction between the steel balls 41 and the limit pressing piece 44, and damage to the profile 200 by the handle 20 is reduced or even eliminated.

Referring to fig. 1-3 and 7-13, the distance D between the center of the fixing hole 111 and the center of the handle mounting hole 112 is equal to the distance D between the center of the limiting hole 411 and the center of the positioning hole 412, and when the base 10 is mounted or dismounted, the limiting pressing piece 44 is driven to rotate so that the positioning hole 412 corresponds to the fixing hole 111, and the fixing screw 12 can be rotated through the positioning hole 412.

Specifically, when the handle limiting unit 40 is to be mounted on the base body 11 and the handle shaft 30, the limiting pressing piece 44 covers the fixing hole 111, so that an installer cannot directly rotate the fixing screw in the fixing hole 111, when the base 10 is mounted, the handle shaft 30 is rotated, the handle shaft 30 drives the limiting pressing piece 44 to rotate, the positioning hole 412 rotates to the fixing hole 111, then the fixing screw 12 is rotated by using a corresponding tool to pass through the positioning hole 412, the screw fixing portion 121 deviates from the mounting hole 201 and moves towards the bottom direction of the base body 11, and the screw fixing portion 121 and the base body 11 clamp the profile 200. When the base 10 is disassembled, the handle shaft 30 is rotated, the handle shaft 30 drives the limiting pressing piece 44 to rotate, the positioning hole 412 rotates to the fixing hole 111, then the fixing screw 12 is rotated through the positioning hole 412 by using a corresponding tool, the screw fixing part 121 moves away from the bottom of the base body 11, and the screw fixing part 121 corresponds to the mounting hole 201, so that the screw fixing part 121 is separated from the profile 200.

It should be noted that the distance D between the center of the fixing hole 111 and the center of the handle mounting hole 112 may be greater than the radius of the limiting presser 44, that is, the fixing hole 111 is located outside the range covered by the limiting presser 44, but this increases the size of the base body 11.

It should be emphasized that the distance D between the center of the fixing hole 111 and the center of the handle mounting hole 112 is equal to the distance D between the center of the limiting hole 411 and the center of the positioning hole 412, that is, the fixing hole 111 is covered by the limiting pressing piece 44, so that the size of the base body 11 can be greatly reduced, and the size of the handle 100 can be greatly reduced, on the one hand, the production cost of the handle 100 can be greatly reduced, and meanwhile, the handle 100 is attractive, elegant and simple.

After the technical scheme is adopted, when the door and window are required to be opened or closed, after the handle shaft 30 is driven to rotate by 90 degrees by driving the handle 20, the steel balls 41 of the handle limiting unit 40 collide with the positioning holes 412 to enable the handle 20 to vibrate slightly and generate slight collision sound, and meanwhile, the steel balls 41 are matched with the positioning holes 412 to limit and position the handle, so that the hand feeling of a user is improved, and the user is reminded that the door and window can be opened or closed when rotating to the position.

It should be noted that the number of the springs 42 may be 2, 3 or other numbers, but the door and window are typically opened by rotating the handle 90 degrees in the conventional design, so the number of the steel balls 41, the springs 42, the spring mounting holes 43 and the positioning holes 412 is typically four.

In this embodiment, the base body accommodating hole 221 is formed at the bottom of the handle shaft mounting portion 22, the lock body mounting hole 53 is formed at the top of the handle shaft mounting portion 22, the lock body 51 is in a cylindrical structure, the lock body mounting hole 53 is a circular hole, the shape of the lock body 51 is adapted to the lock body mounting hole 53, the turntable 52 is in a disc structure, the fixed pin pressing portion 521 is in a similar inverted rotating slide structure on the bottom of the turntable 51, the turntable 52 can be controlled to rotate by rotating the lock cylinder by inserting a corresponding key into the lock cylinder, and the pin head hole 57 penetrates through the return spring mounting hole 56 and the base body accommodating hole 221.

In this embodiment, the fixing holes 111 are locking holes, and two opposite fixing holes 111 are locking holes. The corresponding positions of the limiting pressing pieces 44 are provided with fixing pin perforations 442 for the pin heads 543 to pass through, the pin heads 543, the pin head holes 57, the fixing pin perforations 442 and the fixing holes 111 are in one-to-one correspondence, and the limiting pressing pieces 44 are located at the bottom of the base body accommodating hole 221. When the locking unit 50 is installed, the return spring 55 is installed in the return spring installation hole 56, then the pin body 542 and the pin head 543 on the fixed pin 54 are installed in the return spring 55, the pin head 543 is located at the pin head hole 57 at the bottom of the return spring hole 56, the pin head hole 57 corresponds to the fixed pin through hole 442 and the fixed hole 111 one by one, then the lock body 51 with the rotary disc 52 installed therein is installed in the lock body installation hole 53, after the installation is completed, the pin seat 541 is located between the return spring 55 and the rotary disc 52, and the pin seat 541 is located at the initial position of the fixed pin extrusion 521, that is, the initial position where the fixed pin extrusion 521 is obliquely heightened. When the handle 100 is to be locked, the corresponding key is inserted into the lock cylinder, and the lock cylinder is driven to rotate to drive the turntable 52 to rotate, so that the fixed pin extrusion part 521 continuously extrudes the fixed pin 54 downwards, the return spring 55 is compressed, the pin head 543 sequentially passes through the pin head hole 57 and the fixed pin through hole 442 to the fixed hole 111, and the pin head 543 interacts with the fixed hole 111 to prevent the handle 20 from driving the handle shaft 30 to rotate, thereby realizing the locking handle 100. When the handle 100 is required to be released, the lock core is only required to be driven to rotate the rotary table 52 in the opposite direction, the fixing pin 54 is restored to the original position under the elastic force of the return spring 55, and the handle 100 is unlocked.

Note that, referring to fig. 23, the pin body 542 and the pin head 543 may have the same structure, that is, the fixing pin 54 includes only the pin seat 541 and the pin head 543, and the diameter of the pin head hole 57 is larger than the diameter of the pin head 543.

It should be noted that, the installation process of the locking unit 50 is relatively independent, and the installation sequence can be changed, for example, the locking unit 50 may be installed on the handle 20, then the handle limiting unit 40 may be installed on the base body 11 and the handle shaft 30, then the base 10 may be installed on the profile 200, and finally the handle shaft 30 may be installed on the handle 20.

After the above technical scheme is adopted, the rotary table 52 is driven to rotate, and the fixing pin extrusion part 521 extrudes the fixing pin 54 to enable the pin head 543 to sequentially pass through the pin head hole 57 and the fixing pin perforation 442 and be inserted into the fixing hole 111, so that the handle 100 realizes the locking function. Next, the locking unit 50 is disposed in the handle shaft mounting portion 22, that is, the locking unit 50 is also hidden on the handle 20, so that the handle 100 is beautiful, elegant and simple. In addition, compared with a general handle, in the technical scheme, the locking unit 50 is arranged on the handle 20 instead of being directly arranged on the base 10, and the fixing hole 111 is used as a locking hole, so that the size of the base 10 is obviously reduced, the production raw materials of the base 10 are reduced, the production cost is greatly saved, and the waste is reduced; the reduced size of the base 10 also facilitates hiding of the base 10 within the handle 20, thereby making the handle 100 more aesthetically pleasing.

Referring to fig. 1-3 and 14-20, the pin base 541 is provided with a press-fit portion 544 adapted to the fixing pin pressing portion 521, and the inclined angle of the press-fit portion 544 is equal to that of the fixing pin pressing portion 521.

After the technical scheme is adopted, the pressing matching part 544 matched with the fixing pin pressing part 521 is arranged on the pin seat 541, so that the contact surface of the fixing pin pressing part 521 with the fixing pin 54 is an inclined surface when the fixing pin 54 is pressed, the stress of the pin seat 541 is more uniform, the acting force of the fixing pin pressing part 521 on the fixing pin 54 is more easily converted into axial force and radial force, the pin head 543 can be inserted into the fixing hole 111 with smaller force, and the rotary disc 52 can be rotated with smaller force to lock the handle 100.

Referring to fig. 1-3 and 14-20, the fixing pin pressing part 521 is rotated and inclined to be increased. When the turntable 52 rotates, the pin base 541 slides on the bottom of the turntable 52, and the sliding track is a circular arc, so the projection of the fixed pin pressing portion 521 on the bottom of the turntable 52 is also a circular arc, that is, the fixed pin pressing portion 521 is in a structure of rotating and increasing on the bottom of the turntable 52, similar to an inverted rotating slide structure.

By adopting the above technical scheme, the rotation and the inclination increase of the fixing pin extruding part 521 can not only accomplish the purpose of pressing the fixing pin 54 to enable the pin head 543 to be inserted into the fixing hole 111, but also save raw materials.

It should be noted that, the engagement between the fixing pin pressing portion 521 and the pressing engaging portion 544 may take other forms, for example, a sliding groove (not shown) having a certain arc is provided on the pin base 541, the pressing engaging portion 544 is provided at a bottom of the sliding groove, and the sliding groove is adapted to the fixing pin pressing portion 521; for example, a rotating groove (not shown) with a certain arc is formed at the bottom of the turntable 52, the bottom of the rotating groove is inclined at a certain angle, and the press-fit portion 544 can be placed in the rotating groove.

Referring to fig. 1-3, 14-20, the number of the fixing pins 54 is one or more, and the number of the fixing pin pressing portions 521, the return springs 55, the return spring mounting holes 56, the pin head holes 57, and the fixing holes 111 is identical to the number of the fixing pins.

In the present embodiment, the number of the fixing pins 54 is two, and the number of the fixing pin pressing portion 521, the return spring 55, the return spring mounting hole 56, and the pin head hole 57 is also two. The two fixing pin pressing portions 521 are uniformly distributed at the bottom of the turntable 52, the two return spring mounting holes 56 are also uniformly distributed at the bottom of the lock body mounting hole 53, and the two pin bosses 541 are respectively located between the start position and the end position of the two fixing pin pressing portions 521.

It should be noted that the number of the fixing pins 54 is generally identical to the number of the fixing pin pressing portion 521, the return spring 55, the return spring mounting hole 56, the pin head hole 57, and the fixing hole 111. Of course, the number of the fixing pins 54 may be smaller than the number of the fixing pin pressing portions 521, the return springs 55, the return spring mounting holes 56, the pin head holes 57, and the locking holes.

After the technical scheme is adopted, the number of the fixing pins 54 is set to be two, so that the locking effect can be better, the stress is more uniform when the handle 100 is locked, and the locking effect of the handle 100 is better. The number of the fixing pins 54 is related to the locking capacity of the handle 100, and generally, the greater the number of the fixing pins 54, the greater the locking capacity of the handle 100, but the number of the fixing pins 54 may be generally two, three or four, considering the sizes of the base 10 and the handle 20.

The amount of the inclination angle of the press-fit portion 544 is related to the number of the fixing pin pressing portions 521, the rotation angle of the turntable 52, the distance between the pin head hole 57 and the lock hole, and the like, and the inclination angle of the press-fit portion 544 is generally between 10 degrees and 80 degrees.
