Description

Technical Field

[0001] The utility model relates to the technical field of door and window hardware accessories, in particular to a side-mounted small base handle. Background Art

[0002] Handles facilitate the opening and closing of doors and windows. They are typically connected to locks or lock-like structures, allowing the door or window to be opened through a mechanical mechanism that releases the deadbolt or locking point. Door handles only need to rotate 45 degrees before they automatically rebound. Currently, due to the internal drive structure of existing side-mounted handles, most side-mounted handle bases are unsuitable for ultra-narrow casement profiles. Furthermore, the internal transmission mechanism suffers from poor reliability, short service life, and poor transmission accuracy. Over time, this can lead to a decrease in safety performance and increase the likelihood of accidents. Summary of the Invention

[0003] In order to solve some or certain technical problems existing in the prior art, the purpose of this application is to provide a side-mounted small base handle, which can solve the problem that the side-mounted handle is not suitable for ultra-narrow casement profiles and the internal transmission mechanism has poor reliability. The overall handle is more compact, safe and reliable, and the window can be opened and closed smoothly.

[0004] To solve the above existing technical problems, this application adopts the following technical solutions:

[0005] A side-mounted small base handle comprises a base, a face cover arranged on the base, a shift fork protruding outward from the face cover and arranged in the base, a driving mechanism arranged in the base for laterally moving the shift fork, a main shaft connected to the driving mechanism at one end, and a handle sleeved on the outer end of the main shaft, wherein the driving mechanism comprises a gear coaxially arranged with the main shaft, and a plurality of tooth grooves arranged on the inner side of the shift fork and meshing with the gear, wherein the gear is synchronously rotated with the main shaft through the forward and reverse rotation of the handle, and the shift fork with the tooth groove is laterally moved through the forward and reverse rotation of the gear, thereby driving the transmission mechanism inside the window on which the small base handle is installed to achieve locking and opening of the window.

[0006] Preferably, the main shaft and the gear are integrally formed, and a plurality of circular balls are provided between the side surface of the gear and the base, and the gear contacts the base through the circular balls during rotation.

[0007] Preferably, a plurality of positioning holes are provided in the base, a spring is provided in the positioning holes, a plurality of spherical grooves are provided on the upper end surface of the gear, and the round rolling ball is pushed out by the spring and pressed against the spherical groove on the side of the gear.

[0008] Preferably, a main shaft washer is provided between the gear and the base, the main shaft washer is provided with a plurality of limiting holes, and the round rolling balls are arranged in the limiting holes.

[0009] Preferably, the spindle washer is provided with a plurality of limiting grooves on its upper ring, and a plurality of upwardly protruding limiting blocks are provided on one side of the gear. The spindle washer and the gear are fixed in relative rotation via the limiting grooves and the limiting blocks.

[0010] Preferably, the main shaft and the handle are connected and fixed by a cross-slot countersunk screw, and the round ball is a steel ball.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0019] like Figure 1 and Figure 2 As shown, a side-mounted small base handle includes a base 5, a face cover 3 provided on the base 5, a fork 4 protruding outward from the face cover 3 and provided in the base 5, a driving mechanism provided in the base 5 for laterally moving the fork 4, a main shaft 2 connected to the driving mechanism at one end, and a handle 6 sleeved on the outer end of the main shaft 2, the driving mechanism includes a gear 1 coaxially arranged with the main shaft 2, and a plurality of tooth grooves 16 provided on the inner side of the fork 4 and meshing with the gear 1, the gear 1 is synchronized with the main shaft 2 by the forward and reverse rotation of the handle 6, and the fork 4 with the tooth grooves 16 is laterally moved by the forward and reverse rotation of the gear 1, thereby driving the transmission mechanism inside the window on which the small base handle is installed to achieve locking and opening of the window.

[0020] In actual practical application, the main shaft 2 and the gear 1 are coaxially arranged, which can make the overall width of the base 5 narrower, and there is no need to increase the width due to the internal driving mechanism. At the same time, the driving mechanism is driven by the meshing of the gear 1 and the tooth groove 16, which can make a part of the protruding tooth of the gear 1 extend into the tooth groove 16 on the inner side of the fork 4, further reducing the width of the base 5, so that the small base handle can be side-mounted on the window for casement ultra-narrow profiles. Its driving process simply adopts meshing transmission, and the internal gear 1 transmission increases the reliability of the work and the service life as well as the accuracy of the transmission, effectively solving the problem of poor reliability of the internal transmission mechanism of the existing side-mounted small base handle. As long as the teeth are continuous or the tooth groove 16 is not damaged, there is no problem of damage, so that after it is installed on the window of casement ultra-narrow profile, the overall shape is more compact, safe and reliable, and the window opens and closes smoothly.

[0021] As a further improvement, the main shaft 2 and the gear 1 are integrally formed, and a plurality of circular balls 8 are provided between the side surface of the gear 1 and the base 5 . During the rotation process, the gear 1 contacts the base 5 through the circular balls 8 .

[0022] The main shaft 2 and the gear 1 are integrally formed, which can make their production more convenient, the overall strength is higher, and it is not easy to be damaged. After the main shaft 2 is fixed to the handle, in order to reduce the contact area between the main shaft 2 and the base 5, a number of circular balls 8 are added between the upper side surface of the gear 1 and the inner side surface of the base 5, so that when the main shaft 2 rotates, the gear 1 contacts the base 5 through the circular balls 8, making the main shaft 2 with the gear 1 more flexible and light during rotation. Generally, the number of circular balls 8 is 3-6, which has better stability when supporting.

[0023] A further improvement is that a plurality of positioning holes 15 are provided in the base 5, a spring 7 is provided in the positioning hole 15, a plurality of spherical grooves 13 are provided on the upper end surface of the gear 1, and the round ball 8 is pushed out by the spring 7 and pressed against the spherical groove 13 on the side of the gear 1.

[0024] When the spindle 2 and handle 6 are fixed, the upper end surface of the circular ball 8 is pressed tightly by the spring 7, ensuring elastic contact between the circular ball 8 and the gear 1, so that the two can achieve spherical rolling while avoiding the problem of jamming. At the same time, several spherical grooves 13 are formed on the upper end surface of the gear 1 to limit the circular ball 8 to a certain extent and prevent the circular ball 8 from moving relative to the main shaft 2. The circular ball 8 and spring 7 on the base 5 rotate with the main shaft washer 9 on the main shaft 2, not only ensuring the transmission angle, but also ensuring a smooth feel during rotation.

[0025] A further improvement is that a main shaft washer 9 is provided between the gear 1 and the base 5 , the main shaft washer 9 is provided with a plurality of limiting holes 11 , and the round balls 8 are arranged in the limiting holes 11 .

[0026] During the rotation of the main shaft 2 and the gear 1, in order to ensure the position accuracy of the circular ball 8, a main shaft washer 9 with a limiting hole 11 is installed between the gear 1 and the base 5. The circular ball 8 is located in the limiting hole 11 on the main shaft washer 9, so that the circular ball 8 will not move in relative position during use, and the strength of the gear 1 can also be prevented from being damaged.

[0027] A further improvement is that a plurality of limiting grooves 10 are provided on the main shaft washer 9, and a plurality of upwardly protruding limiting blocks 12 are provided on one side of the gear 1. The main shaft washer 9 and the gear 1 are fixed in relative rotation by the limiting grooves 10 and the limiting blocks 12.

[0028] The spindle washer 9 and the gear 1 are fixed in relative rotation by the engagement of the limiting groove 10 and the limiting block 12, which makes it easier to produce the limiting hole 11 and simplifies the fixing structure between the spindle washer 9 and the gear 1.

[0029] A further improvement is that the spindle 2 and the handle 6 are connected and fixed with a cross recessed countersunk screw 14, and the round rolling ball 8 is a steel ball. The use of cross recessed countersunk screws to connect and fix the spindle and the handle has a simpler structure, a higher connection security, and a smaller size. In addition, the use of steel balls for the round rolling balls has a longer service life and greater rolling flexibility.

[0030] The above-mentioned embodiments are only preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by technicians in this field based on the present application shall fall within the scope of protection required by the present application.
