Description

Technical Field

[0001] The invention relates to the technical field of mechanical design, and in particular to a one-button fixing support device. Background Art

[0002] The most common type of fixed support device is the support rod. Its basic working principle is to achieve a certain range of extension and retraction through the relative rotation of the screw and the nut. At present, most of the fixed support devices such as the punch-free curtain or hanging telescopic support rod are more and more widely used. Its main installation method is to fix one end and have a threaded movable end at the other end. The movable end is rotated to adjust and fix it between two walls or between two fixed objects.

[0003] The existing fixed support device has the problem that users need to rotate different numbers of circles due to different support sizes. After rotating many circles of empty travel, they sometimes need to use tools to further tighten, which is cumbersome to operate and inconvenient to install. At the same time, this structure mainly relies on threads to bear the support force. As the support force increases, it is difficult to rotate between the screw and the nut, and the thread is easy to wear. After multiple disassembly and assembly, the thread will slip, affecting the use.

[0065] Example 2

[0066] As a specific implementation of the embodiment of the present invention, please refer to Figures 1 to 16 The structure of a one-button fixed support device provided in this embodiment is basically the same as that of embodiment 1, except that the propulsion mechanism 1 also includes a propulsion assembly 12, a speed change assembly 13, a housing 14 and an elastic member 15, wherein the propulsion assembly 12 is respectively connected to the support block 4 and the locking limit mechanism 2; the speed change assembly 13 is connected to the propulsion assembly 12; the housing 14 is respectively connected to the propulsion assembly 12, the support body 3, the locking limit mechanism 2 and the speed change assembly 13; the elastic member 15 is respectively connected to the housing 14 and the propulsion assembly 12. A rack 111 is provided on the button 11, and the rack 111 is engaged with the speed change assembly 13. An elastic torsion spring 16 is provided between the button 11 and the housing 14. A limit pin 17 is provided on the housing 14, and the limit pin 17 is used to limit the movement angle of the button 11. The propulsion assembly 12 and the housing 14 can move relative to each other.

[0067] The button 11 is arranged on the surface of the shell 14, and the movement of the propulsion component 12 is controlled by the cooperation of the rack 111 and the speed change component 13. The shell 14 mainly plays a supporting role. For example, when it is applied to the fixed installation of the curtain, in the initial state, the locking limit mechanism 2 limits the movement of the propulsion component 12, and the elastic member 15 is in a compressed state and has a certain elastic potential energy. The button 11 is in a rebound state under the action of the elastic torsion spring 16. At this time, the angle between the button 11 and the shell 142 is the largest, and the gear portion 132 of the speed change component 13 is separated from the rack 111 arranged at the lower end of the button 11, and the rack 111 is arc-shaped; when used, the locking limit mechanism 2 cancels the restriction on the propulsion component 12, and the propulsion component 12 is pushed outward a certain distance under the action of a part of the elastic potential energy released by the elastic member 15, with The moving support block 4 contacts the wall to reach a state of preliminary pre-tightening; press the button 11, the rack 111 cooperates with the speed change assembly 13 to drive the propulsion assembly 12 to move outward to produce a secondary displacement, so that the support block 4 is more tightly connected to the wall, achieving a one-button clamping effect, which is simple to operate and has a better clamping effect; after one-button clamping, the locking limit mechanism 2 is automatically locked in the state where the button 11 is pressed, and the propulsion assembly 12 is locked in this position, so that the propulsion assembly 12 and the shell 14 cannot be relatively displaced; when disassembling, the locking limit mechanism 2 is set to the unlocked state, and the shell 14 is manually pushed toward the wall, and the propulsion assembly 12 is pushed into the shell 14, and the locking limit mechanism 2 automatically locks the propulsion assembly 12, and the entire device returns to the initial state, realizing the free extension and retraction of the device for easy reuse. Compared with the existing fixed support device threaded connection control extension and retraction structure, the propulsion mechanism 1 can realize the extension and retraction of the entire device with one-button operation, without the need for frequent tightening or the use of other tools, and is not easily damaged after repeated use.

[0068] In this embodiment, the locking limit mechanism 2 includes a locking limiter 21, a cover 22 and a bracket 23, wherein the locking limiter 21 is connected to the propulsion assembly 12; the cover 22 is connected to the housing 14 and is provided with a button 221, and the button 221 is connected to the locking limiter 21; the bracket 23 is connected to the locking limiter 21 and the cover 22 respectively. In the initial state, the button 221 is in a pop-up state, and the locking limiter 21 is in a locked state to limit the movement of the propulsion assembly 12; after the button 221 is pressed, the locking limiter 21 is in an unlocked state through the mutual cooperation between the button 221 and the locking limiter 21, and the propulsion assembly 12 can move freely. The cover 22 plays the role of support and dustproof, and its appearance is beautiful and has a certain ornamental value. The button 221 passes through the button hole 225 on the cover 22, and the button 221 is slidably connected to the cover 22. The bracket 23 is provided with a mounting slot and a positioning slot 235. The cover 22 is provided with a mounting bayonet 222, a positioning boss 223 and a mounting buckle 224 below. The mounting slot is used to cooperate with the mounting bayonet 222 for fixing, and the positioning slot 235 cooperates with the positioning boss 223 for positioning. The mounting buckle 224 is connected and fixed in cooperation with the housing 14. The locking limiter 21 is fixed between the cover 22 and the bracket 23. The bracket 23 mainly provides support for the locking limiter 21 so that the locking limiter 21 can operate better. The button 221 directly controls the unlocking. After the button 221 pops up, it can be automatically locked. No complicated operation is required. The operation is simple. Only the button 221 needs to be used to unlock and automatically lock with one click, so as to better fix the propulsion assembly 12.

The positioning rod 122 is located at the rear end of the propulsion assembly 12. Here, as long as the above-mentioned positioning rod 122, pushing rod 121 and elastic member 15 can achieve the relevant performance functions, they are all within the scope of protection of this application document.

The track adapter 1433 can adapt to tracks of different shapes. The rear end of the track adapter 1433 has a track mounting groove, and the shape of the track mounting groove is determined according to the shape of different tracks. The elastic member 15 is located between the push rod 121 and the base 143. During the movement, the elastic member 15 drives the push rod 121 to move linearly. The top cover 141 is a plastic cover buckled on the front end of the shell 142. The movement hole 1411 can be located in the middle of the top cover 141.

The middle rotating shaft 2113 of the seesaw structure is fixed to the housing 14.

[0079] The specific operation process is that in the initial state, the button 221 pops up, the buckle part 2121 is engaged with the ratchet part 2111, the cylindrical mounting shaft 2131 is at the uppermost end of the waist hole, the elastic stretching member 216 and the elastic body 215 are in a normal state without force, the limit buckle 214 is in contact with the limit block 124, and the propulsion mechanism 1 is in a locked state; after pressing the button 221, the button 221 drives the swing arm 2123 to move downward, the elastic body 215 is in a compressed state, the block 212 drives the connector 213 to move downward, and the connector 213 pushes the connecting arm 2143 to rotate downward along the rotating shaft 2142 The locking gear 2112 and the locking rack 125 can move freely, and the propulsion mechanism 1 is in an unlocked state. After the button 221 is released, the button 221 and the swing arm 2123 pop up under the action of the elastic body 215, and the swing arm 2123 drives the seesaw portion 2122 to rotate to realize the downward movement of the buckle portion 2121. The locking member 211 is engaged with the ratchet wheel 2111, and the ratchet wheel 2111 can only rotate forward and cannot be reversed. The propulsion assembly 12 connected to the locking ratchet wheel 211 can also only move forward and cannot be reversed. At the same time, the connector 213 moves in the waist hole and produces relative displacement with the card block 212. The elastic stretching member 216 is stretched. At this time, the limit block 124 is located at the lower end of the limit buckle 214, which supports the limit buckle 214 and fixes the limit buckle 214 to the current state. Because the button 221 is in the installed state without external force, it is in a loose state, the card buckle part 2121 is engaged with the ratchet wheel 2111, and the propulsion assembly 12 cannot be It can be reversed, so it cannot be directly disassembled. During disassembly, press the button 221 to lift the buckle part 2121, and the buckle part 2121 is separated from the ratchet part 2111. The propulsion assembly 12 can be reversed and an external force is applied to the limit block 124. The limit block 124 is pushed back to the initial state and separated from the limit buckle 214. The support effect of the limit block 124 on the limit buckle 214 is cancelled, and the elastic stretching member 216 drives the connecting member to finally pull the limit buckle 214 to rotate along the rotating shaft 2142 and contact the limit block 124, thereby realizing the limiting effect on the propulsion mechanism 1 and locking the limit mechanism 2 to return to the initial state.
