Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a handle assembly. Background Art

[0002] The handle is usually installed on doors and windows to facilitate gripping. The handle includes a handle and a square shaft. The two ends of the square shaft are connected to the handle and the lock. The lock can be opened by turning the handle, and the handle can also facilitate opening and closing doors and windows. In order to improve the feel of the handle, an elastic positioning piece is usually added to the installation structure of the handle. The elastic positioning piece is usually fixed to the square shaft of the handle by bolts. The installation process is relatively cumbersome and is not conducive to improving production efficiency. Utility Model Content

[0003] The utility model aims to provide a handle assembly to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems is as follows: a handle assembly, comprising: a square shaft, with an edge arranged on the outer circumference, and a first slot opened on the outer circumference of the square shaft; a base, sleeved on the square shaft; a spring frame, sleeved on the square shaft, a first block elastically connected to the inner side of the spring frame that can be embedded in the first slot, the spring frame and the edge clamp the base; a positioning member, arranged between the spring frame and the base.

[0005] This technical solution has at least the following beneficial effects: during assembly, the base and the spring frame are first inserted into the square shaft front and back respectively, one side of the base is against the edge, and then the positioning piece is put between the spring frame and the base, and then the spring frame is against the side of the base away from the edge. At this time, the first clamping block is embedded in the first clamping groove, and the spring frame is fixed on the square shaft. Therefore, it is convenient to fix the positioning piece, the spring frame and the base on the square shaft, the installation operation is simple, and the assembly efficiency is high, thereby improving the production efficiency.

[0006] As a further improvement of the above technical solution, an elastic sheet is connected between the spring frame and the first clamping block, and an elastic gap is provided between the side of the elastic sheet away from the first clamping block and the spring frame. The first clamping block can be embedded in the first clamping slot by elastically deforming the elastic sheet toward the position of the elastic gap, which has a simple structure and is easy to manufacture.

[0007] As a further improvement of the above technical solution, the spring frame, the elastic sheet and the first clamping block are integrally formed, so that the spring frame, the elastic sheet and the first clamping block have better integrity, and the manufacturing process can be simplified, the production efficiency can be improved, and the production cost can be reduced, so as to improve the economic efficiency of the product.

[0008] As a further improvement of the above technical solution, the elastic gap is embedded with a backstop plug. After the spring frame is fixed to the square shaft, the backstop plug can be embedded in the elastic gap, so that the first clamping block cannot deform toward the elastic gap and escape from the first clamping groove, thereby improving the connection stability between the spring frame and the square shaft.

[0009] As a further improvement of the above technical solution, a second clamping block is elastically connected to one side of the anti-retraction plug, and a second clamping groove for the second clamping block to be embedded in the inner side of the spring frame is provided. After the anti-retraction plug is embedded, the second clamping block is embedded in the second clamping groove, which can ensure the stability of the anti-retraction plug, thereby further improving the connection stability between the spring frame and the square shaft.

[0010] As a further improvement of the above technical solution, the positions of the anti-retraction plug on both sides of the second clamping block are provided with elastic notches. The provision of the elastic notches can make the anti-retraction plug position where the second clamping block is located have better elastic deformation ability, thereby improving the reliability of the second clamping block and the second clamping slot.

[0011] As a further improvement of the above technical solution, limit strips are installed on both sides of the anti-retraction plug, and the limit strips on both sides of the anti-retraction plug are respectively on both sides of the elastic sheet. The anti-retraction plug can not only limit the elastic sheet from deforming into the elastic gap, but also limit the position of the two sides of the elastic sheet, thereby improving the stability of the elastic sheet to prevent the first card block from escaping from the first card slot. In addition, the limit strips on both sides can also provide a positioning function for the anti-retraction plug, so that the anti-retraction plug can be embedded in the elastic gap, and the second card block can be smoothly embedded in the second card slot to fix the anti-retraction plug.

[0012] As a further improvement of the above technical solution, the bottom wall of the first clamping groove is an arc surface surrounding the axis of the square shaft, and one end surface of the first clamping block embedded in the clamping groove is also set as an arc surface. The setting of the arc surface can increase the area of ​​the second clamping block contacting the side wall of the second clamping groove, improve the connection strength between the spring frame and the square shaft, and thus ensure that the spring frame and the square shaft are not easy to fall out when subjected to forces in the axial direction and the direction of separation.

[0013] As a further improvement of the above technical solution, it also includes a handle, one end of the square shaft is embedded in the end of the handle, the handle is threadedly installed with a set screw with a tapered cylinder at one end, the square shaft is provided with a tapered groove for the tapered cylinder to be embedded, and the axis of the tapered groove does not coincide with the axis of the tapered cylinder. The square shaft is embedded in one end of the handle, and the tapered cylinder can be embedded in the tapered groove of the square shaft by rotating the set screw, and the square shaft is fixed in the handle to complete the connection between the square shaft and the handle. In addition, by adjusting the depth of the set screw, the depth of the tapered cylinder embedded in the tapered groove can be adjusted. Since the axis of the tapered groove does not coincide with the axis of the tapered cylinder, the relative position of the square shaft and the handle can be appropriately adjusted to adjust the feel of the handle when it is turned.

[0014] As a further improvement of the above technical solution, the positioning member includes a marble, a positioning groove is provided at one end of the base close to the spring frame, a mounting hole for accommodating the marble is provided at one side of the spring frame close to the base, an elastic member is installed between the marble and the bottom wall of the mounting hole, and the elastic member provides elastic force to embed the marble into the positioning groove. The positioning effect of the marble embedded in the positioning groove can provide a positioning effect for the handle, and in addition, the elastic member is embedded in the mounting hole of the spring frame, the marble is placed in the positioning groove, and when the spring frame and the base are covered, the elastic member and the marble can be easily installed between the spring frame and the base, so as to improve the efficiency of assembly.

[0028] Reference Figure 1-7 A handle assembly includes a square shaft 10, a base 20 and a spring frame 30. An edge 11 protrudes outward from the middle periphery of the square shaft 10, and the edge 11 is formed integrally with the square shaft 10. The base 20 is disc-shaped, and a circular hole matching the outer periphery of the square shaft 10 is opened in the middle of the base 20, so that the base 20 can be sleeved in the square shaft 10. A through hole is also opened in the middle of the spring frame 30, so that the spring frame 30 can also be sleeved on the square shaft 10. The spring frame 30, the base 20 and the edge 11 are arranged side by side in sequence.

[0029] Elastic sheets 50 are arranged on two opposite inner side walls of the through hole of the spring frame 30. The two elastic sheets 50 are arranged symmetrically with respect to the center plane of the spring frame 30, and the elastic sheet 50 is integrally connected with the spring frame 30 at one end close to the base 20. The first clamping block 40 is integrally connected to the end of the elastic sheet 50 away from the base 20, and the first clamping block 40 is located at one side of the elastic sheet 50 close to the square shaft 10. The two side walls of the square shaft 10 on which one end of the spring frame 30 is sleeved are provided with first clamping grooves 41, and the two first clamping grooves 41 correspond to the two first clamping blocks 40 respectively. It should be noted that an elastic gap 51 is arranged between the two elastic sheets 50 and the spring frame 30 at the side away from the end of the base 20 and facing away from the first clamping block 40, so as to allow the elastic sheet 50 to be elastically deformed in the direction of the elastic gap 51.

[0030] When the spring frame 30 is inserted into the square shaft 10, the outer wall of the square shaft 10 pushes the first clamping block 40, so that the elastic sheet 50 is elastically deformed in the direction of the elastic gap 51, so as to allow the spring frame 30 to continue to be inserted into the square shaft 10. When the first clamping block 40 corresponds to the position of the first clamping slot 41, the first clamping block 40 is embedded in the first clamping slot 41 under the elastic force of the elastic sheet 50. At this time, the side of the spring frame 30 close to the base 20 just touches the side of the base 20 away from the edge 11, so that the spring frame 30 can be fixed in the square shaft 10, and the base 20 can be firmly clamped between the spring frame 30 and the edge 11. Among them, the spring frame 30, the elastic sheet 50 and the first clamping block 40 can be made of plastic as raw material by injection molding. It should be noted that an inclined chamfer is provided between the end of the first clamping block 40 close to the base 20 and the elastic sheet 50, so as to assist the elastic deformation of the elastic sheet 50, so that the first clamping block 40 can be smoothly embedded in the first clamping slot 41.

[0031] In other embodiments, the elastic connection between the first clamping block 40 and the spring frame 30 may not be achieved through the elastic sheet 50, but by providing a slide groove in the spring frame 30, the first clamping block 40 is radially slidably arranged in the slide groove, and a coil spring is installed between the bottom wall of the slide groove and the first clamping block 40, so that the first clamping block 40 is elastic in the radial direction relative to the spring frame 30, so as to ensure that the first clamping block 40 can be smoothly embedded in the first clamping groove 41.

[0032] A positioning member is also installed between the spring frame 30 and the base 20. The positioning member includes an elastic member 73 and a marble 72. Four mounting holes 71 are provided at one end of the spring frame 30 close to the base 20. The four mounting holes 71 are arranged around the axis of the square shaft 10. The four elastic members 73 are respectively embedded in the four mounting holes 71. Four positioning grooves 70 are provided at one end of the base 20 close to the spring frame 30. The four positioning grooves 70 are arranged one by one with the four mounting holes 71. One end of the four marbles 72 abuts against one end of the elastic member 73 away from the bottom wall of the mounting hole 71, and the other end is embedded in the positioning groove 70. After the spring frame 30 is installed, under the action of the elastic member 73, the marble 72 can remain embedded in the positioning groove 70. When the square shaft 10 is rotated to make the spring frame 30 and the base 20 rotate relatively, the elastic force of the elastic member 73 can be overcome, so that the marble 72 can move from one positioning groove 70 to another adjacent positioning groove 70 to achieve the positioning of the square shaft 10. In other embodiments, the number of the elastic member 73, the marble 72, the mounting hole 71 and the positioning slot 70 can be two, three or five according to actual needs. The elastic member 73 can be a coil spring.

[0033] In order to ensure the stability of the connection between the spring frame 30 and the square shaft 10, after the installation of the spring frame 30 is completed, a stop plug 60 can be embedded in the elastic gap 51 on both sides. The thickness of the stop plug 60 is the same as the thickness of the elastic gap 51, so that the elastic sheet 50 can no longer deform toward the elastic gap 51 and the first clamping block 40 can be disengaged from the first clamping groove 41, thereby ensuring the stability of the connection between the spring frame 30 and the square shaft 10.

[0034] A second clamping block 61 is elastically connected to one end of the anti-retraction plug 60 which is embedded in the elastic gap 51 and away from the elastic sheet 50. A second clamping groove 62 is provided on the inner side of the spring frame 30, i.e., on one side wall of the elastic gap 51 away from the elastic sheet 50. After the anti-retraction plug 60 is embedded in the elastic gap 51, the second clamping block 61 is clamped in the second clamping groove 62 to prevent the anti-retraction plug 60 from escaping from the elastic gap 51.

[0035] Specifically, the stop plug 60 and the second clamping block 61 are made of plastic integrally molded, and elastic notches 63 are provided at the positions of the stop plug 60 near both sides of the second clamping block 61, so that the part of the stop plug 60 where the second clamping block 61 is located can form a strip structure, and the strip structure can have a large elastic deformation ability. It should be noted that the thickness of the strip structure is less than the thickness of the stop plug 60, that is, there is a deformable space between the side of the strip structure facing away from the second clamping block 61 and the spring frame 30, so that the strip structure can be deformed, so that the second clamping block 61 can be smoothly inserted into the second clamping groove 62 to fix the stop plug 60. It should be noted that an inclined chamfer is provided between the end of the second clamping block 61 near the base 20 and the strip structure, and the inclined chamfer can assist the elastic deformation of the strip structure, so that the second clamping block 61 can be smoothly embedded in the second clamping groove 62.

[0036] In addition, a gap is provided between the two sides of the elastic sheet 50 and the inner wall of the spring frame 30, and a limit strip 64 is protruded on both sides of the anti-retraction plug 60. The limit strip 64 is integrally formed with the anti-retraction plug 60. When the anti-retraction plug 60 is embedded in the elastic gap 51, the limit strips 64 on both sides are respectively located at the two sides of the elastic sheet 50, thereby limiting the position of the elastic sheet 50 and providing a positioning effect for the anti-retraction plug 60.

[0037] The bottom wall of the first clamping groove 41 is an arc surface 42, and the arc surface 42 surrounds the axis of the square shaft 10. The first clamping block 40 is adapted to the first clamping groove 41, that is, the side end of the first clamping block 40 is also set as an arc surface. When the first clamping block 40 is embedded in the first clamping groove 41, the arc surface of the first clamping block 40 fits the arc surface 42 of the first clamping groove 41. At this time, the side area of ​​the first clamping block 40 that conflicts with the first clamping groove 41 is large, which improves the connection stability between the spring frame 30 and the square shaft 10 while minimizing the impact on the overall strength of the square shaft 10.

[0038] This embodiment also includes a handle 80, one end of which is provided with a stepped groove, and each step of the stepped groove is respectively adapted to the shape of the base 20, the spring frame 30 and the square shaft 10, so that after the base 20, the spring frame 30, the positioning member and the square shaft 10 are assembled into a combination, one end of the combination can be adapted to be embedded in the stepped groove. A set screw 81 is threadedly installed on one side of the handle 80, and conical grooves 83 are provided on both sides of one end of the square shaft 10 embedded in the stepped groove. After the set screw 81 is screwed into the stepped groove from the outside of the handle 80, it is embedded in the conical groove 83 of the square shaft 10, so that the square shaft 10 can be fixed in the stepped groove, and the combination and the handle 80 are fixedly installed.

[0039] When the assembly is inserted into the stepped groove, there is a certain gap between the square shaft 10 and the bottom wall. At this time, the axis of the tapered groove 83 does not coincide with the axis of the tapered cylinder 82. Therefore, when the set screw 81 is continuously screwed into the stepped groove, the tapered cylinder 82 contacts the side wall of the tapered groove 83 and pushes the square shaft 10 to move, so that the edge 11 on the square shaft 10 can clamp the base 20 and the spring frame 30. The depth of screwing in the set screw 81 can be adjusted according to different needs, and the feel of the handle 80 when rotating can be appropriately adjusted, so as to meet the user's hand feel needs.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
