Description

Five-direction tact switch push handle assembly

The technical field is as follows:

the invention belongs to the technical field of switches, and particularly relates to a five-direction light-touch switch push handle assembly.

Background art:

the light touch switch is an electronic switch, also called a key switch, when in use, the switch can be switched on by lightly pressing the switch, when the hand is loosened, the switch is switched off, the internal structure of the light touch switch realizes the on-off by the elastic force of a metal elastic sheet (movable contact sheet), the light touch switch has the advantages of small contact resistance load, diversified specifications and the like, and is widely applied to the aspects of electronic equipment, white household appliances and the like: audio-visual products, digital products, remote controllers, communication products, household appliances, security products, toys, computer products, fitness equipment, medical equipment, currency examining pens, laser pen keys and the like. The tact switch in the prior art mainly comprises a base, an elastic sheet, a push handle, a plum blossom handle, a cover plate (an upper frame) and a terminal, and is characterized in that: one type of tactile switch is disclosed in ZL 201710895837.0. However, when the existing tact switch is pushed, the push handle swings up and down, left and right in the shifting process, and the defects of 360-degree rotation and swinging and the like easily cause the problem of disordered functions of products.

The invention content is as follows:

the invention firstly solves the technical problems that: provides a five-direction tact switch push handle assembly capable of eliminating push direction errors.

In order to solve the technical problems, the invention adopts the technical scheme that: five to light touch switch push away handle subassembly, including the switch frame, go up the frame center and offer the first connecting hole of installation plum blossom handle, it has the plum blossom handle to peg graft in the first connecting hole, and plum blossom handle central axial has seted up the second connecting hole, and it has the push handle to peg graft in the second connecting hole, and the push away handle lower extreme is connected with the separation blade, circumference equipartition has four spouts that extend along first connecting hole axial on the first connecting hole inner wall, the plum blossom handle includes spliced pole and the plum blossom shape clamp plate of fixed connection at the spliced pole lower extreme that inserts in the first connecting hole, be provided with the direction sand grip with the spout one-to-one correspondence on the spliced pole outer peripheral face, the external diameter of spliced pole is less than the internal diameter of first connecting hole, and the spliced pole is located the center of first connecting hole, has the swing clearance between arbitrary direction sand grip and the corresponding spout and supplies the spliced, the upper end surface of the baffle at the lower end of the push handle is abutted against the lower end surface of the pressing plate.

As a preferable scheme, the second connecting hole is a square hole with four chamfered edges, and the push handle is a prism with a cross section matched with the shape of the second connecting hole.

The invention has the beneficial effects that: according to the invention, the sliding groove is arranged on the inner side wall of the first connecting hole, and the guide convex strip is correspondingly arranged on the outer peripheral surface of the connecting column of the plum blossom handle, so that the swinging direction of the plum blossom handle can be effectively limited, and the technical problem that the five-direction light-touch switch pushing direction error can be effectively eliminated by limiting the swinging direction of the plum blossom handle.

The invention further limits the swinging and rotating problems of the prism through the connection relationship between the push handle of the prism and the square second connecting hole.

Description of the drawings:

the following detailed description of embodiments of the invention is provided in conjunction with the appended drawings, in which:

FIG. 1 is an exploded view of the present invention;

FIG. 2 is a schematic structural view of the assembled state of the present invention;

FIG. 3 is a schematic view of the structure of the push handle swinging in the right direction;

fig. 4 is a schematic view of the structure of the push handle swinging out of the right direction.

In fig. 1 to 4: 1. go up frame, 2, plum blossom handle, 201, spliced pole, 202, clamp plate, 3, first connecting hole, 4, second connecting hole, 5, push handle, 6, separation blade, 7, spout, 8, direction sand grip, 9 swing clearance.

The specific implementation mode is as follows:

specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the five-way tact switch push handle assembly comprises a switch upper frame 1, a first connection hole 3 for installing a plum blossom handle 2 is arranged at the center of the upper frame 1, the plum blossom handle 2 is inserted into the first connection hole 3, a second connection hole 4 is axially arranged at the center of the plum blossom handle 2, a push handle 5 is inserted into the second connection hole 4, and a baffle 6 is connected to the lower end of the push handle 5. the five-way tact switch push handle assembly is characterized in that four sliding grooves 7 axially extending along the first connection hole 3 are circumferentially and uniformly distributed on the inner wall of the first connection hole 3, the plum blossom handle 2 comprises a connection column 201 inserted into the first connection hole 3 and a plum blossom-shaped pressing plate 202 fixedly connected to the lower end of the connection column 201, guide convex strips 8 corresponding to the sliding grooves 7 one by one are arranged on the outer circumferential surface of the connection column 201, the outer diameter of the connection, any direction is raised the line 8 and is corresponded to and has swing clearance 9 between the spout 7 and supply the swing of spliced pole 201, push away handle 5 and pass second connecting hole 4 from the 2 lower extremes of plum blossom handle and stretch out outside frame 1, push away 6 up end of separation blade and the clamp plate 202 lower extreme butt of handle 5 lower extreme. The second connecting hole 4 is a square hole with four chamfered edges, and the push handle 5 is a prism with a cross section matched with the shape of the second connecting hole 4.

The working process of the invention is as follows: as shown in fig. 3, when the pushing handle 5 is pushed, the pushing handle 5 drives the plum blossom handle 2 to swing, when the pushing direction of the pushing handle 5 is consistent with the direction pointed by any one of the guiding convex strips 8, the guiding convex strip 8 can be smoothly inserted into the corresponding sliding groove 7, and the sliding groove 7 further forms a guide for the guiding convex strip 8, thereby eliminating the error of the pushing direction of the pushing handle 5. When the pushing direction of the pushing handle 5 is between two adjacent guiding convex strips 8, as shown in fig. 4, the guiding convex strips 8 on both sides of the swinging direction abut against the inner walls of the mouth parts of the two sliding grooves 7 at the same time due to the swinging of the plum blossom handle 2, so that the plum blossom handle 2 cannot swing further, and only after the swinging direction of the pushing handle 5 is adjusted, one of the guiding convex strips 8 can be inserted into the corresponding sliding groove 7, thereby eliminating the error of the pushing direction of the pushing handle 5.

The above embodiments are merely illustrative of the principles and effects of the present invention, and some embodiments in use, and are not intended to limit the invention; it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications belong to the protection scope of the present invention.
