DETAILED DESCRIPTION

[0038] In order to better understand and implement, the technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model.

[0039] In the description of the utility model, it needs to be explained that the directions or position relations indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are the directions or position relations shown based on the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.

[0040] Unless otherwise defined, all the technical and scientific terms used in the present document have the same meanings as those commonly understood by the person skilled in the art to which the utility model belongs. The terms used in the specification of the utility model are only for the purpose of describing the specific embodiments and are not intended to limit the utility model.

[0041] Referring to Figures 1-7 The utility model provides a kind of off-axis handle, including base 1, transmission mechanism 2, handle 3 and transmission shaft (not shown in drawing), the accommodating cavity is opened in the inside of this base 1;The transmission mechanism 2 is configured in accommodating cavity;Wherein, the transmission mechanism 2 includes the driving wheel 21 rotationally arranged in accommodating cavity, the driven wheel 22 rotationally arranged with driving wheel 21 and transmission belt 23 respectively wound on driving wheel 21 and driven wheel 22;The handle 3 is located in the side of base 1 and its one end is transmissionally connected with driving wheel 21;The transmission shaft is located in the other side of base 1 and its one end is transmissionally connected with driven wheel 22.

[0042] It can be understood that, in actual use process, when user rotates handle 3, can drive driving wheel 21 rotation, to further drive transmission belt 23 and driven wheel 22 rotation, and finally drive transmission shaft rotation, transmission shaft rotates and can drive hardware in transmission lock box to move.In the utility model, since handle 3 rotation does not directly drive transmission shaft rotation, but drives transmission shaft by the transmission of transmission mechanism 2, and driving wheel 21 and driven wheel 22 are arranged at intervals, i.e. the rotation shaft of handle 3 and the rotation shaft on transmission shaft are at a certain distance apart.Therefore, when the frame edge section material surface of door frame is relatively narrow, i.e. the rotation shaft of transmission shaft is relatively close to the edge of frame edge section material, the rotation shaft of handle 3 is still at a certain distance apart from frame edge section material, and this arrangement increases the operation space when user operates handle, so as to reduce the probability of finger being pinched.

[0043] Furthermore, the off-axis handle of the utility model realizes transmission cooperation through the transmission belt 23 wound on the driving wheel 21 and the driven wheel 22, compared with the traditional meshing transmission of transmission gear, not only the structure is simpler, and the precision requirement of the processing and assembly of the transmission belt 23 is lower, the cost is lower, in addition, if the traditional transmission gear is used for meshing transmission, two or even more transmission gears are usually arranged to form a gear train with stable structure, and the transmission mechanism 2 formed by the driving wheel 21, the driven wheel 22 and the transmission belt 23 in the application has stable and reliable structure, less parts, simple structure and high practicability.

[0044] Referring to Figures 2-3 The off-axis handle further comprises a transmission wheel 4 penetratingly arranged on the base 1 and being in clamping connection with the handle 3 and the driving wheel 21, when the handle 3 is rotated, the transmission wheel 4 and the driving wheel 21 can be synchronously driven to rotate. Specifically, the transmission wheel 4 comprises a transmission wheel body 41, one side of the transmission wheel body 41 is provided with a boss 42, a plurality of first protrusions 421 are annularly arranged on the boss 42, a plurality of first recesses 31 corresponding to the first protrusions 421 are formed on the handle 3, thus, the transmission connection between the handle 3 and the transmission wheel 4 can be realized by clamping the first protrusions 421 into the first recesses 31, in addition, the other side of the transmission wheel body 41 is provided with a second recess 43, the driving wheel 21 is provided with a second protrusion 211, thus, the transmission connection between the driving wheel 21 and the transmission wheel 4 can be realized by clamping the second protrusion 211 into the second recess 43.

[0045] In addition, a first through hole 422 is formed in the transmission wheel 4, a second through hole 212 is formed in the driving wheel 21 and is in communication with the first through hole 422, a first mounting hole 32 is formed in the handle 3 and is in communication with the first through hole 422. Therefore, when the three are assembled and connected, one side of the transmission wheel 4 is clamped with the handle 3 first, the other side of the transmission wheel 4 is clamped with the driving wheel 21, and finally a fastener 5 is sequentially penetrated through the second through hole 212 and the first through hole 422 and connected with the first mounting hole 32 to realize the connection and fixation between the three, as shown in Figure 7 .

[0046] Preferably, the first mounting hole 32 is a screw hole, and the fastener 5 is a connecting screw matched with the screw hole.

[0047] In the embodiment, a first shaft hole 11 and a second shaft hole 12 in communication with the accommodating cavity and arranged at intervals are formed in the base 1, the transmission wheel 4 penetrates through the first shaft hole 11, and the driven wheel 22 penetrates through the second shaft hole 12.

[0048] Referring to Figure 2 , Figure 3 and Figure 6The off-axis handle further comprises an elastic abutting structure 6 arranged in the accommodating cavity, the elastic abutting structure 6 comprises a steel ball 61 and a spring 62 abutting at one end of the steel ball 61, and under the elastic force of the spring 62, the steel ball 61 can abut against the transmission wheel 4 and drive the driving wheel 21 to tension the transmission belt 23, thereby ensuring the transmission reliability of the transmission mechanism 2.

[0049] In addition, in actual use, the handle 3 generally has multiple operating positions, and in a certain operating position, the hardware connected with the transmission lock box can move a certain distance. Therefore, in order to ensure that the handle 3 can be accurately positioned to a certain operating position, the handle 3 is generally provided with a positioning device inside. In the utility model, a plurality of positioning grooves 411 are arranged on the outer periphery of the transmission wheel body 41, when the handle 3 is rotated, the transmission wheel 4 can be driven to rotate and the steel ball 61 can be selectively clamped into the positioning groove 411, so as to realize the positioning of the transmission wheel 4 and the handle 3.

[0050] The positioning grooves 411 are arranged in four, and the four positioning grooves 411 are uniformly distributed on the transmission wheel 4 in the circumferential direction (that is, the interval between the adjacent two positioning grooves 411 is 90 degrees); the elastic abutting structure 6 is arranged in two, and the two elastic abutting structures 6 are arranged at an angle of 90 degrees. It can be understood that in general, the existing door and window handle usually has four positions of vertical upward, vertical downward, horizontal left and horizontal right. Therefore, the four positioning grooves 411 of the utility model can better meet the use requirement. In order to improve the stability of the positioning of the transmission wheel 4, two elastic abutting structures 6 are arranged in the application, and the two steel balls 61 are clamped into the two positioning grooves 411 respectively to realize clamping and fixing, so as to prevent the transmission wheel 4 from rotating, and further avoid the rotation of the handle 3.

[0051] Of course, it should be noted that in other embodiments, the number and distribution mode of the positioning grooves 411 and the elastic abutting structure 6 can be selected according to actual needs, and are not limited to the above description.

[0052] In addition, a plurality of clamping grooves 412 are further arranged on the transmission wheel 4 between the adjacent two positioning grooves 411, when the handle 3 is rotated, the transmission wheel 4 can be driven to rotate and the steel ball 61 can be selectively clamped into the clamping groove 412 and emit a crisp mechanical sound, thereby increasing the hand feeling when the handle 3 is rotated, and further enabling the user to obtain better use experience.

[0053] It can be understood that the groove depth of the positioning groove 411 is greater than the groove depth of the clamping groove 412, so that when the steel ball 61 is clamped into the positioning groove 411, the user needs to use more force to move the handle 3 to drive the steel ball 61 to pass through the positioning groove 411, thereby ensuring the firmness of the positioning of the handle 3; on the contrary, when the steel ball 61 is clamped into the clamping groove 412, the user only needs to use less force to move the handle 3 to drive the steel ball 61 to pass through the clamping groove 412.

[0054] Therefore, the elastic abutting structure 6 integrates the three functions of tensioning the transmission belt 23, positioning the handle 3 and producing mechanical sound, so that the product volume can be more compact, the installation space is saved, and the production cost is reduced.

[0055] Referring again to Figures 2-3 The base 1 is provided with a mounting groove 13 in the accommodating cavity, and the spring 62 and part of the steel balls 61 are arranged in the mounting groove 13. The other end of the spring 62 abuts against the groove wall of the mounting groove 13. Therefore, under the elastic force of the spring 62, the steel balls 61 can be driven to partially extend out of the mounting groove 13 and abut against the transmission wheel 4.

[0056] Further, a cover plate 8 is arranged on one side of the base 1 to seal the accommodating cavity. The cover plate 8 not only prevents dust and impurities from entering the accommodating cavity to cause the transmission mechanism 2 to be stuck, but also limits and fixes the transmission mechanism 2 to a certain extent to prevent it from being separated.

[0057] In addition, the base 1 is provided with a second mounting hole 14 for mounting on the door and window profile. Therefore, the base 1 can be assembled and fixed by screwing a screw through the second mounting hole 14 and fixing it on the door and window profile. In addition, a face plate 7 is arranged on the other side of the base 1. The face plate 7 can shield the second mounting hole 14 on the base 1, thereby improving the appearance of the off-axis handle.

[0058] In addition, in the embodiment, the transmission mechanism 2 is a chain wheel and chain transmission mechanism. The driving wheel 21 is a driving sprocket, the driven wheel 22 is a driven sprocket, and the transmission belt 23 is a chain. Therefore, the chain wheel and chain transmission mechanism is used for transmission. The chain transmission does not have the problems of elastic sliding and slipping, has high working reliability, high transmission efficiency, large carrying capacity, and strong environmental adaptability.

[0059] Of course, it can be understood that in other embodiments, the transmission mechanism 2 can also be a belt wheel transmission mechanism, and the belt is prone to slipping. However, the present application can tension the transmission belt through the elastic abutting structure 6, thereby ensuring reliable transmission.

[0060] In summary, the off-axis handle provided by the present application has the following advantages:

[0061] (One) the off-axis handle of the utility model, through setting respectively winding on the transmission belt 23 of driving wheel 21 and driven wheel 22 to realize transmission cooperation, compared with the meshing transmission of traditional transmission gear, not only structure is more simple, and the precision requirement of the processing and assembly of parts is lower, and the cost is lower;In addition, the transmission mechanism of the driving wheel 21, driven wheel 22 and transmission belt 23 is relatively stable and reliable, and the reliability of product use is improved.

[0062] (Two) the off-axis handle of the utility model, through setting elastic abutment structure 6, under the elastic force of spring 62, the steel ball 61 can abut transmission wheel 4 and drive driving wheel 21 to tension transmission belt 23, so as to ensure the transmission reliability of transmission mechanism;In addition, a plurality of positioning grooves 411 and clamping grooves 412 are also set up on the transmission wheel 4, when rotating handle 3 until steel ball 61 is clamped into positioning groove 411, it can realize the positioning of transmission wheel 4, and then realize the positioning of handle 3;At the same time, when rotating handle 3, the steel ball 61 can be clamped into clamping groove 412 and emit crisp mechanical sound, so as to increase the hand feeling when rotating handle 3, and then the user obtains better use experience. Therefore, the elastic abutment structure 6 combines the three functions of tensioning transmission belt 23, positioning handle 3 and emitting mechanical sound, so that the product volume can be made more compact and small, and then the installation space is saved, and the production cost is reduced.

[0063] It should be noted that when an element is referred to as "fixed to" or "provided on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or indirectly connected to the other element.

[0065] In addition, in the description of the utility model, the meaning of "a plurality of" and "several" is two or more than two, unless otherwise explicitly and specifically limited.
