Description

Technical Field

[0001] The utility model relates to the technical field of door and window hardware, in particular to a novel baseless handle. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] Doors and windows are common objects in our daily lives. To facilitate opening and closing, they are often fitted with handles. Common handles are categorized as either base handles or baseless handles. Baseless handles, unlike base handles, remove the base components that are installed on doors and windows, and place the mounting components inside the handle, resulting in a simpler and more elegant appearance.

[0004] Patent application number 201910766421.8 discloses a pre-installed baseless handle, comprising a wheel seat, a wheel, and a wheel gasket. The wheel seat is provided with a countersunk hole, the wheel is provided with a second avoidance groove corresponding to the countersunk hole, and a plurality of blind holes. The blind holes are provided with an elastic member and a retaining member located at one end of the elastic member. The wheel gasket is located between the wheel seat and the wheel, connected to the wheel seat, and provided with a retaining hole that cooperates with the retaining member and a first avoidance groove corresponding to the countersunk hole. Thus, when the wheel is rotated, the retaining member can be selectively engaged in the retaining hole to achieve position limiting.

[0005] Among them, since a first avoidance groove connected to the countersunk hole is also provided on the wheel gasket, in order to prevent the locking piece from being stuck in the first avoidance groove and the countersunk hole when the wheel rotates, the baseless handle is also provided with a pad. A sealing block that cooperates with the first avoidance groove extends radially inward on the inner ring of the pad. The sealing block is engaged with the first avoidance groove to seal the first avoidance groove.

[0006] It can be seen from this that since the above-mentioned baseless handle requires an additional pad to block the first avoidance groove, it not only increases the number of parts and leads to increased costs, but also makes the structure of the entire handle more complicated, and at the same time, assembly is more troublesome and requires higher assembly precision. Utility Model Content

[0007] In order to overcome the defects of the above-mentioned prior art, the utility model provides a new baseless handle, which is provided by arranging a positioning plate between the fixed seat and the rotating wheel seat. The positioning plate cooperates with the rotating wheel seat in transmission and the positioning plate can limit and fix the elastic positioning component, thereby preventing the marbles from falling during rotation. There is no need to set a pad for blocking like traditional handles, which simplifies the product structure, reduces the number of product parts, reduces costs, and has higher assembly efficiency and lower assembly precision requirements.

[0008] The technical solution adopted by the present invention to solve the problem is:

[0009] A novel baseless handle comprises a handle and a shaft core assembly embedded in the handle, wherein:

[0010] The shaft core assembly includes a shaft core, a fixing seat sleeved on the shaft core and used to be fixed on the profile, a runner seat sleeved on the shaft core and located above the fixing seat, and a positioning piece sleeved on the shaft core and located between the fixing seat and the runner seat, wherein the runner seat is connected and fixed to the shaft core;

[0011] The bottom ring of the revolving wheel seat is provided with a plurality of elastic positioning components, the elastic positioning components include an elastic member and a marble abutting against one end of the elastic member, the positioning plate is provided with positioning holes corresponding to the plurality of elastic positioning components, the aperture of the positioning holes is smaller than the diameter of the marble, the marble abuts against the positioning holes and partially protrudes from the positioning holes; the fixing seat is provided with a plurality of positioning grooves;

[0012] When the handle is rotated, the wheel seat and the positioning piece can be driven to rotate simultaneously and the marble can be selectively engaged with the positioning groove to position the handle.

[0013] Furthermore, it also includes a gasket arranged on the fixing seat. When the marble is stuck in the positioning groove, the positioning piece abuts against the gasket and is spaced a certain distance in height from the fixing seat.

[0014] Furthermore, a mounting groove for placing the positioning piece is provided on the fixing seat. When the positioning piece is placed in the mounting groove, the top surface of the positioning piece is higher than the top surface of the fixing seat.

[0015] Furthermore, a plurality of slots are arranged around the fixing seat, and when the handle is rotated, the marbles can be driven to abut against the slots to make a sound.

[0016] Furthermore, the fixing seat is provided with a countersunk hole for installation on the profile, and the fixing seat is provided with a guide slope near the countersunk hole for guiding the movement of the marble.

[0017] Furthermore, the positioning piece is provided with an avoidance hole connected to the countersunk hole, and the wheel seat is provided with an avoidance groove connected to the avoidance hole.

[0018] Furthermore, it also includes a first screw, a through hole is opened on the wheel seat, and a first screw hole connected to the through hole is opened at one end of the shaft core. The first screw passes through the through hole and is threadedly connected in the first screw hole to realize the connection and fixation between the wheel seat and the shaft core.

[0019] Furthermore, it also includes a second screw, a second screw hole is provided on the handle, and a clamping hole connected to the second screw hole is provided on the wheel seat. The second screw thread is passed through the second screw hole and extends into the clamping hole to tighten the handle and the wheel seat to achieve the connection and fixation between the handle and the wheel seat.

[0020] Furthermore, it also includes a transmission shaft, and the other end of the shaft core is provided with a groove for inserting one end of the transmission shaft.

[0021] Furthermore, the transmission shaft is a square shaft.

[0022] To sum up, the utility model provides a baseless handle, which is provided by arranging a positioning plate between the fixed seat and the rotating wheel seat. The positioning plate cooperates with the rotating wheel seat in transmission and the positioning plate can limit and fix the elastic positioning component, thereby preventing the marbles from falling during rotation. There is no need to set a pad for sealing like a traditional handle, which greatly simplifies the product structure, reduces the number of product parts, reduces costs, and has higher assembly efficiency and lower assembly precision requirements.

[0030] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0032] 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.

[0033] See Figure 1-5 The utility model provides a new type of baseless handle, including a handle 1, an axis core assembly and a transmission shaft (not shown in the figure). A cavity 11 is opened inside the handle 1, and the axis core assembly is embedded in the cavity 11; one end of the transmission shaft extends into the profile and is connected to the transmission mechanism in the profile, and the other end is inserted into the axis core assembly to realize the transmission connection.

[0034] The shaft core assembly includes a shaft core 2, a fixing seat 3 sleeved on the shaft core 2 and used to be fixed to the profile, a roller seat 4 sleeved on the shaft core 2 and located above the fixing seat 3, and a positioning plate 5 sleeved on the shaft core 2 and located between the fixing seat 3 and the roller seat 4. The roller seat 4 is connected and fixed to the shaft core 2. In addition, a plurality of elastic positioning components 6 are provided around the bottom of the roller seat 4. The elastic positioning components 6 include an elastic member 61 and a marble 62 abutting one end of the elastic member 61. The positioning plate 5 is provided with positioning holes 51 corresponding to the plurality of elastic positioning components 6. The aperture of the positioning hole 51 is smaller than the diameter of the marble 62. The marble 62 abuts the positioning hole 51 and partially extends out of the positioning hole 51. The bottom end of the marble 62 abuts the fixing seat 3. Thus, through the snap-fitting engagement between the marble 62 and the positioning hole 51, a transmission connection between the two can be achieved.

[0035] In addition, a positioning groove 31 is formed around the fixing seat 3. When the handle 1 is rotated, the wheel seat 4 and the positioning piece 5 are driven to rotate simultaneously and the marble 62 is selectively engaged with the positioning groove 31 to position the handle 1.

[0036] Therefore, the present invention sets a positioning piece 5 between the fixed seat 3 and the rotating wheel seat 4, and the positioning piece 5 cooperates with the rotating wheel seat 4 in transmission. The positioning piece 5 can limit and fix the elastic positioning component 6, thereby preventing the marble 62 from falling during the rotation process. There is no need to set a pad for blocking like a traditional handle, thereby greatly simplifying the product structure, reducing the number of product parts, and reducing costs. At the same time, the assembly efficiency is higher and the assembly precision requirements are lower.

[0037] In the embodiment of the present invention, the bottom ring of the wheel seat 4 is provided with blind holes 41 corresponding to a plurality of elastic positioning components 6 , and the elastic positioning components 6 are arranged in the blind holes 41 .

[0038] In the embodiment of the present invention, the elastic member 61 is a spring, one end of the spring abuts against the top wall of the blind hole 41 , and the other end abuts against the marble 62 .

[0039] Furthermore, a gasket 7 is provided on the fixing seat 3. When the marble 62 is locked in the positioning groove 31, the positioning piece 5 abuts against the gasket 7 and is spaced a certain distance in height from the fixing seat 3. In this way, by providing the gasket 7, it is possible to prevent the positioning piece 5 from directly abutting against the fixing seat 3 when the marble 62 is locked in the positioning groove 31, thereby reducing the friction generated between the two, thereby facilitating the rotation of the marble 62.

[0040] In the embodiment of the present invention, the fixing seat 3 is provided with a mounting groove 35 for placing the positioning piece 5 and adapted to its shape. When the positioning piece 5 is placed in the mounting groove 35 , the top surface of the positioning piece 5 is higher than the top surface of the fixing seat 3 .

[0041] See also Figure 1 The fixing base 3 is also provided with a plurality of card slots 32 located between two adjacent positioning slots 31. When the handle 1 is rotated, the marbles 62 can be driven to abut against the card slots to emit a metal impact sound, thereby making the handle more advanced.

[0042] Furthermore, the fixing base 3 is provided with a countersunk hole 33 for mounting on the profile, and a guide slope 34 is provided on the fixing base 3 near the countersunk hole 33 to guide the movement of the marble 62. Thus, by providing the guide slope 34, when the marble 62 partially extends into the countersunk hole 33, when the handle 1 is rotated and the marble 62 is rotated, the marble 62 can move along the guide slope 34 and gradually escape from the countersunk hole 33, preventing the marble from being unable to escape from the countersunk hole 33 due to a large height difference.

[0043] In the embodiment of the present invention, the guiding inclined surfaces 34 are respectively located on both sides of the counterbore 33 .

[0044] See also Figure 1 The positioning piece 5 is further provided with an avoidance hole 52 connected to the countersunk hole 33, and the runner seat 4 is provided with an avoidance groove 43 connected to the avoidance hole 52. Thus, by providing the avoidance hole 52 and the avoidance groove 43, the shaft core 2, the fixing seat 3, the runner seat 4, the plurality of elastic positioning components 6, and the positioning piece 5 can be assembled into a shaft core assembly, and then a connecting screw can be used to sequentially pass through the avoidance groove 43, the avoidance hole 52, and the countersunk hole 33 and connected and fixed to the profile to achieve connection and fixation of the fixing seat 3, thereby achieving post-installation of the fixing seat 3.

[0045] Furthermore, the baseless handle further includes a first screw 8. The wheel seat 4 has a through hole 42, and one end of the shaft core 2 has a first screw hole 21 connected to the through hole 42. The first screw 8 passes through the through hole 42 and is threadedly engaged in the first screw hole 21 to securely connect the wheel seat 4 to the shaft core 2. Furthermore, the handle further includes a second screw 9. The handle 1 has a second screw hole 12 connected to the concave cavity 11, and the wheel seat 4 has a locking hole connected to the second screw hole 12. The second screw 9 is threadedly engaged in the second screw hole 12 and extends into and presses against the locking hole 44 on the wheel seat 4 to securely connect the handle 1 to the wheel seat 4.

[0046] In the embodiment of the present invention, the other end of the shaft core 2 is provided with a groove 22 for inserting one end of the transmission shaft; the transmission shaft is a square shaft.

[0047] To sum up, the utility model provides a baseless handle, which is provided by arranging a positioning plate 5 between the fixed seat 3 and the rotating wheel seat 4. The positioning plate 5 is matched with the rotating wheel seat 4 in transmission and the positioning plate 5 can limit and fix the elastic positioning component 6, thereby preventing the marble 62 from falling during the rotation process. Therefore, there is no need to set a pad for blocking like the traditional handle, thereby greatly simplifying the product structure, reducing the number of product parts, and reducing costs. At the same time, the assembly efficiency is higher and the assembly precision requirements are lower.
