Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.
The specific structure of the handle according to the embodiment of the present invention is described below with reference to fig. 1 to 8.
As shown in fig. 1 to 8, fig. 1 discloses a handle, which comprises a handle 1, a fixing seat 2, a connecting shaft 3 and a fastener 4. An installation groove 11 is formed at one end of the handle 1, and an internal tooth portion 72 is provided in the installation groove 11. The fixing seat 2 is arranged in the mounting groove 11, and the fixing seat 2 can be connected with the profile piece. The connecting shaft 3 rotates and sets up in fixing base 2, and the both ends of connecting shaft 3 are equipped with first external tooth portion 31 and second external tooth portion 32 respectively, and first external tooth portion 31 can mesh with internal tooth portion 72, and second external tooth portion 32 can mesh with the drive mechanism on the section bar spare. The fastener 4 wears to establish in fixing base 2, and the one end of fastener 4 is connected with the diapire of mounting groove 11.
It will be appreciated that the fixing base 2 is arranged in the mounting groove 11 and is connected with the profile, so that the fixing base 2 can be fixedly connected to the profile, the fastening piece 4 is arranged in the locking hole 23 in the fixing base 2 in a penetrating manner and is connected with the bottom wall of the mounting groove 11, so that the handle 1 can be firmly and reliably sleeved on the fixing base 2 through the fastening piece 4, and only a small gap is reserved between the notch of the mounting groove 11 and the profile, and no additional base for fixedly arranging the handle 1 on the profile is needed. Simultaneously, the inner tooth part 72 can rotate along with the rotation of the mounting groove 11 when the handle 1 rotates on the fixed seat 2, the first outer tooth part 31 meshed with the inner tooth part 72 can be driven to rotate when the inner tooth part 72 rotates, the first outer tooth part 31 rotates to enable the connecting shaft 3 to rotate relative to the fixed seat 2, the second outer tooth part 32 can also rotate along with the rotation of the connecting shaft 3, and then the second outer tooth part 32 can be meshed with the transmission mechanism and drive the transmission mechanism to move. Because the second external tooth part 32 is arranged on the connecting shaft 3, when the handle is connected with the transmission mechanism on the profile piece, the handle and the transmission mechanism can not be additionally provided with gear structures, so that the volume of the handle and the transmission mechanism can be further reduced, the transmission shaft can directly drive the meshing structure in the transmission mechanism to move, the transmission reliability of the handle and the transmission mechanism is improved, and the jamming phenomenon between the handle and the transmission mechanism is reduced. Because the handle of this embodiment does not set up the base, has less volume between mounting groove 11, fixing base 2, connecting axle 3 and the fastener 4, can make the handle install and use in the less place in space, the inside compact structure of mounting groove 11 is reliable simultaneously, can make handle 1 establish on the section bar spare and accurately reliably drive mechanism motion, still be convenient for the firm installation of handle on the section bar spare.
According to the handle of this embodiment, the mounting structure in the mounting groove 11 is simple and compact, can be convenient for the firm installation of handle on the section bar spare, and second external tooth portion 32 is established on the transmission shaft, can further reduce the volume of handle and drive mechanism and be favorable to handle drive mechanism motion to make the handle can be applicable to less space's installation occasion, improved the suitability of handle.
In some alternative embodiments, as shown in fig. 2, the cross-sectional areas of the first external tooth portion 31 and the second external tooth portion 32 are similar, so that the second external tooth portion 32 has a smaller size, the connection space between the handle and the transmission mechanism can be further reduced, and the handle can drive the transmission mechanism to move in a smaller space, so that the applicability of the handle is further improved. Of course, the actual size of the second external tooth portion 32 can be determined according to actual requirements, and the cross-sectional area of the second external tooth portion 32 is not intended to limit the present invention.
In some alternative embodiments, as shown in fig. 2, the connecting shaft 3 further includes a rotating section 33, where the rotating section 33 can be rotatably connected to the transmission mechanism, so as to facilitate the stable driving of the transmission mechanism by the handle.
In some embodiments, as shown in fig. 2 and fig. 4, the bottom wall of the mounting groove 11 is provided with a plurality of grooves 111 uniformly distributed around the central axis of the mounting groove 11, the handle further includes a plurality of elastic members 5, each elastic member 5 is disposed corresponding to one groove 111, one end of each elastic member 5 is abutted in the fixing seat 2, and the other end is abutted on the bottom wall of the mounting groove 11 or the groove 111.
It can be understood that the distance between the bottom wall of the groove 111 and the fixed seat 2 is greater than the distance between the bottom wall of the mounting groove 11 and the fixed seat 2, when the handle 1 rotates on the fixed seat 2, the bottom wall of the mounting groove 11 and the bottom wall of the groove 111 are respectively abutted against the elastic member 5, and the elastic force applied by the elastic member 5 to the bottom wall of the mounting groove 11 is greater than the elastic force applied by the elastic member 5 to the bottom wall of the groove 111, so that when the handle 1 is rotated by an operator, the fixed seat 2 can apply different forces to the handle 1, and the operator can approximately judge the rotating position of the handle 1 according to the different forces, thereby improving the use experience of the operator.
In addition, the elastic member 5 can be set in a relaxed state when being abutted against the bottom wall of the groove 111, and in a compressed state when being abutted against the bottom wall of the mounting groove 11, so that the hand feeling difference of operators when the handle 1 is positioned at different positions of the fixing seat 2 can be further improved.
For example, the number of elastic members 5 and the number of grooves 111 can be set to 4, the included angle between two adjacent elastic members 5 and the center of the mounting groove 11 is 90 degrees, the bottom wall of the groove 111 can be abutted on the elastic member 5 when the handle 1 is at the initial position, the bottom wall of the groove 111 is abutted again on the elastic member 5 when the handle 1 rotates 180 degrees, and meanwhile, the connecting shaft 3 can be enabled to drive the transmission mechanism to move by a preset distance when the handle 1 rotates 180 degrees, so that when an operator rotates the handle 1, the transmission mechanism can be determined to move by the preset distance according to the force of the second sensing that the bottom wall of the groove 111 is abutted on the elastic member 5, and the use experience of the operator is improved.
In some embodiments, as shown in fig. 2 and 5, the end of the fixing base 2 facing the handle 1 is provided with a plurality of blind holes 21, each elastic member 5 is provided in one blind hole 21, and the elastic member 5 includes an elastic portion 51 and a rigid portion 52. One end of the elastic portion 51 abuts against the bottom wall of the blind hole 21. The rigid portion 52 abuts against the other end of the elastic portion 51, and a part of the rigid portion 52 protrudes out of the fixing base 2.
It can be appreciated that the arrangement of the blind hole 21 not only can facilitate the installation of the elastic member 5, but also is beneficial to improving the utilization rate of the space occupied by the fixing seat 2. The handle 1 compresses tightly the rigidity portion 52 and makes a part of rigidity portion 52 butt on the inner wall of blind hole 21 in the motion process, rigidity portion 52 compresses tightly elastic portion 51 so that elastic portion 51 compresses in vertical direction under the drive of handle 1, the setting of rigidity portion 52 and elastic portion 51 can avoid elastic piece 5 to appear crooked phenomenon in the use, and only rigidity portion 52 can butt on the inner wall of blind hole 21 and receive the pressure of horizontal direction to the irreversible damage that the elastic piece 5 caused in the handle 1 rotation process has been reduced, the life of elastic piece 5 has been prolonged. In addition, in the present embodiment, the rigid portion 52 can be abutted against the bottom wall of the groove 111 during the use of the elastic member 5, and the rigid portion 52 has rigidity, so that obvious use feedback can be provided to the operator.
Illustratively, the rigid portion 52 can be configured as a steel ball, and when the operator drives the handle 1 to rotate, the sidewall of the groove 111 applies less pressure to the steel ball, so that the bottom wall of the mounting groove 11 adjacent to the groove 111 can more conveniently compress the steel ball, thereby reducing the resistance applied when the operator rotates the handle 1. In addition, the arrangement of the steel balls can avoid the phenomenon that the rigid part 52 is blocked in the groove 111, thereby reducing the failure phenomenon that the elastic piece 5 can not rotate the handle 1.
Illustratively, the elastic portion 51 can be provided as a spring.
In some embodiments, as shown in fig. 2, the handle 1 further includes a positioning member 6, where the positioning member 6 is disposed on a bottom wall of the mounting groove 11, the fixing base 2 abuts against the positioning member 6, and a plurality of communication holes 61 are disposed on the positioning member 6, and each communication hole 61 is disposed corresponding to one of the grooves 111.
It can be appreciated that the setting of the positioning element 6 can improve the interval between the bottom wall of the mounting groove 11 and the bottom wall of the groove 111, so as to further improve the difference between the elastic force applied by the elastic element 5 to the bottom wall of the mounting groove 11 and the elastic force applied by the elastic element 5 to the bottom wall of the groove 111, so as to improve the hand feeling difference of the operator when the handle 1 is located at different positions of the fixing seat 2, and further improve the use experience of the operator. In addition, setting up on the diapire of mounting groove 11 can also prolong the life of setting element 6, also can be convenient for unpack apart the handle and change when setting element 6 wearing and tearing, reduced the cost of maintenance of handle.
Optionally, the locating piece 6 can be set to have the stainless steel spare of outstanding wearability, and the wearing and tearing between locating piece 6 and the elastic component 5 can be showing in the setting of stainless steel spare, and the setting of locating piece 6 can prolong the life of handle under the prerequisite of being convenient for processing.
Of course, in other embodiments of the present invention, the positioning member 6 may be integrally formed on the bottom wall of the mounting groove 11, in which case the end of the handle 1 provided with the mounting groove 11 may be formed by using a wear-resistant material, such as stainless steel, for prolonging the service life of the handle. In other embodiments of the present invention, the mounting and molding manner of the positioning member 6 is not particularly limited.
