Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, and more specifically to a handle without a base which is easy to clamp. Background Art

[0002] The baseless handle is an emerging product in the development of the door and window industry. In the past two years, with the prevalence of simple and narrow-framed windows, this type of handle has also become popular. The baseless handle, which is easy to clamp, requires two steps to install and remove from the door and window profiles, which brings inconvenience to use. In addition, when the handle is used to control the opening and closing of doors and windows, the joints of its components are easily worn and damaged, shortening its service life.

[0003] For example, announcement No. CN217760451U discloses a clamping type baseless handle, which includes a handle and a round rod. The bottom end of the handle is rotatably connected to the round rod. A fixing device is provided at the bottom of the round rod. The fixing device includes a sleeve. The outer wall of the sleeve is rotatably connected to the round rod. The inner wall of the sleeve is slidably connected to the vertical rod. The outer wall of the vertical rod is rotatably connected to the vertical block. The outer wall of the vertical block is slidably connected to the round rod. The bottom groove of the vertical block is rotatably engaged with a round ball.

[0004] It can be seen from the above-mentioned public scheme that when the handle is disassembled, it is necessary to first loosen the threaded block counterclockwise, and then press the button to drive the vertical block to squeeze the top rod to rotate and shrink, and then remove the profile. However, when the handle is fixed in use, the top rod and the profile are clamped, so that the button cannot be pressed down too much, which brings inconvenience to the opening and closing operation of doors and windows, and the wall thickness of the connection between the plug block and the handle is relatively thin, and when rotating the vertical rod, the plug block needs to be squeezed downward out of the socket connected to the handle, which makes the socket wear faster and cause damage, thereby damaging the handle and shortening its service life. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a baseless handle that is easy to clamp. The baseless handle that is easy to clamp, through the provision of an extrusion sleeve, a clamping block, a jack and a through hole, not only facilitates the installation and fixation of the handle and the profile, but also the clamping block can be removed after the extrusion sleeve is loosened counterclockwise. The structure is simple and will not affect the operation of the button. In addition, through the provision of buttons, latch teeth and gears, it is not only convenient for the user to hold the handle rod to operate the button clamping gear to drive the vertical rod to rotate, and then to open and close doors and windows, but also its structure will not affect the strength of the connection of the handle assembly, thereby extending the service life of the handle.

The baseless handle that is easy to clamp, through the arranged extrusion sleeve, clamping block, jack and through hole, is not only convenient for the installation and fixation of the handle and the profile, but also the clamping block can be removed after the extrusion sleeve is loosened counterclockwise. The structure is simple and will not affect the operation of the button. In addition, through the arranged buttons, clamping teeth and gears, it is not only convenient for the user to hold the handle rod to operate the button clamping gear to drive the vertical rod to rotate, and then open and close the doors and windows, but also its structure will not affect the strength of the connection of the handle assembly, thereby extending the service life of the handle.

[0008] Furthermore, a limiting groove is provided on the surface of the profile plate, a concentric and coaxial socket is provided at the bottom of the limiting groove, and a through hole is provided on the inner wall of the socket. The through holes are equidistantly distributed in a circular shape with the center of the socket as the center of the circle.

[0009] Furthermore, an external thread is provided on the surface of the connecting column, a threaded hole is provided in the middle of the extrusion sleeve, and the shape of the extrusion sleeve is polygonal. The extrusion sleeve can move up and down on the surface of the connecting column through the thread.

[0010] Furthermore, the clamp block is cylindrical in shape, and the side of the clamp block is provided with anti-slip blocks distributed in an annular shape and at equal intervals. The anti-slip blocks are arc-shaped or rectangular in shape. After the clamp block rotates, the anti-slip blocks are detached from the corresponding through holes, thereby preventing the clamp block from being separated from the profile plate at will.

[0011] Furthermore, the inner wall of the limiting groove is in contact with and extruded from the end surface of the extrusion sleeve, and the inner diameter of the limiting groove is greater than the maximum outer diameter of the extrusion sleeve, thus having a limiting function.

[0012] Furthermore, the outer diameter of the limit plate is larger than the inner diameter of the sliding hole, and the surface of the limit plate is provided with symmetrical guide holes to facilitate the limit plate to slide on the surface of the guide rod.

[0013] Furthermore, the surface of the button is in contact with the inner wall of the sliding hole, so that the button has the function of telescopic movement.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] This solution not only facilitates the installation and fixation of the handle and the profile by providing an extrusion sleeve, a clamping block, a jack and a through hole, but also allows the clamping block to be removed after the extrusion sleeve is loosened counterclockwise. The structure is simple and will not affect the operation of the button.

[0016] This solution provides buttons, latches and gears, which not only makes it convenient for users to hold the handle bar to operate the button to clamp the gear to drive the vertical rod to rotate, thereby opening and closing doors and windows, but also its structure will not affect the strength of the connection of the handle assembly, thereby extending the service life of the handle.

The vertical rod 3 belongs to the prior art, one end of which is connected to the door and window switch mechanism to control the switch of the door and window. Its composition structure and working principle are well known to those skilled in the art. The inner wall of the rotating sleeve 15 is fixedly sleeved with a connecting column 16, and the outer side of the connecting column 16 is provided with a symmetrical plane to facilitate fixing its rotation position by a wrench. The inner wall of the connecting column 16 is rotatably connected with the vertical rod 3 through a bearing, and one end of the vertical rod 3 is provided with a gear 31. One end of the connecting column 16 is fixedly sleeved with a clamping block 4, and the surface of the connecting column 16 is connected with an extrusion sleeve 5 through a thread, and a profile plate 6 is clamped between the extrusion sleeve 5 and the clamping block 4.

[0025] A limiting groove 61 is provided on the surface of the profile plate 6, and a concentric and coaxial socket 62 is provided at the bottom of the limiting groove 61. A through hole 63 is provided on the inner wall of the socket 62. The through holes 63 are equidistantly distributed in a ring shape with the center of the socket 62 as the center of the circle.
