Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning devices, and particularly relates to a release latch with an elastic arm and a conductive tube with the release latch. Background Art

[0002] A release latch is a common mechanical component widely used in various devices and products. Its main function is to fix or lock two or more parts to prevent them from separating from each other under unexpected circumstances. At the same time, it can also quickly and conveniently unlock the latch by pressing or operating a certain part (such as a button) when needed to achieve the separation of the parts.

[0003] Traditional release latches usually consist of multiple parts. For example, a telescopic tube with a safety button latch disclosed in the publication number CN200993141Y includes a telescopic tube and a latch. The latch includes a button, a pin, a spring piece, a lock sleeve, and a fixing screw. The lock sleeve is fixed to the end of the outer tube of the telescopic tube through a fixing screw provided at the bottom of the lock sleeve. There is a groove above the lock sleeve, and the button is arranged in the groove above the lock sleeve. The button and the lock sleeve are fixed together through a pin, and both ends of the pin are fixed on the side walls of the groove. The button can rotate around the pin. The tail of the button is provided with a fixed tail wing, and there is a hole on the outer tube of the telescopic tube below the fixed tail wing for the tail wing to move up and down. The front end of the button is a pressing handle, and there is a spring piece between the pressing handle below and the groove above the lock sleeve. There are small holes on the contact surface of the spring piece with the groove, and there are protrusions on the groove at the position matching the small holes. The protrusions pass through the small holes on the spring piece to control the movement of the spring piece. These parts need to be assembled together through an assembly process, which not only increases the production cost, but also may cause loosening or damage between the parts during long-term use, affecting the stability and service life of the product.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] According to one aspect of the present application, a release lock buckle with an elastic arm is disclosed, specifically, as Figures 1 to 4 As shown, the release lock 1 includes a button 11 and an elastic arm 12. The elastic arm 12 is integrally formed with the button 11. The elastic arm 12 is arranged below the button 11. The button 11 includes a stabilizing portion 111, a releasing portion 113 and a connecting portion 112 located between the stabilizing portion 111 and the releasing portion 113. The connecting top surface of the connecting portion 112 is lower than the stabilizing top surface of the stabilizing portion 111 and the releasing top surface of the releasing portion 113. The elastic arm 12 extends from the connecting bottom surface of the connecting portion 112 to a direction away from the connecting top surface.

[0024] It can be understood that the one-piece molding design of the release lock buckle 1 in the embodiment of the application can improve the stability of the overall structure, reduce production costs, and improve production efficiency. Furthermore, the connection top surface of the connecting portion 112 is lower than the stabilizing top surface of the stabilizing portion 111 and the releasing top surface of the releasing portion 113, which can enable the button 11 to better disperse the force when subjected to force, thereby preventing the button 11 from being damaged due to excessive force; further, the elastic arm 12 extends from the connecting bottom surface of the connecting portion 112 in a direction away from the connecting top surface, so that the elastic arm 12 can effectively provide a reverse force to the button 11 after being subjected to force, so that the button 11 can be quickly reset, thereby improving the response speed of the button 11.

[0025] In some embodiments, the elastic arm 12 is an arc-shaped structure.

[0026] In some embodiments, the protruding portion of the arc-shaped structure faces the stabilizing portion 111 , and the recessed portion of the arc-shaped structure faces the releasing portion 113 .

[0027] In some other embodiments, the protruding portion of the arc-shaped structure faces the releasing portion 113 , and the recessed portion of the arc-shaped structure faces the stabilizing portion 111 .

[0028] It is understandable that the elastic arm 12 is designed as a concave-convex arc structure, so that the elastic arm 12 can effectively provide a reverse force to the key 11 after being subjected to force, so that the key 11 can be quickly reset, thereby improving the response speed and service life of the key 11.

[0029] Further, it should be noted that the arc structure can be a regular circular arc structure or an irregular arc structure. For example, the elastic arm 12 can be designed with a larger arc at one end closer to the connecting portion 112 and a smaller arc at the end farther away from the connecting portion 112. In this way, through the transition of the two arcs, while achieving elastic reset, it can also play a certain buffering role in the pressing of the button 11, improving the user's pressing experience.

[0030] It can be understood that designing the elastic arm 12 as an arc structure is only a preferred exemplary illustration. In other feasible solutions, the elastic arm 12 can also be designed as a straight-line structure, with a design of the first angle between the elastic arm 12 and the stabilizing portion 111, and a design of the second angle between the elastic arm 12 and the releasing portion 113. It should be noted that the first angle can be smaller than the second angle, or the first angle can be larger than the second angle.

[0031] In some embodiments, the elastic arm 12 extends from the connection between the stabilizing portion 111 and the connecting portion 112 in a direction away from the connecting top. It can be understood that the elastic arm 12 starts to extend from the connection between the stabilizing portion 111 and the connecting portion 112, which can increase the distance between the releasing button 11 and the elastic arm 12, increase the lever length of the button 11, reduce the force of the button 11, and improve the button 11 experience.

[0032] In some embodiments, the release latch 1 is made of an elastic material. Exemplarily, the elastic material can be thermoplastic elastomer (TPE). TPE is a material with rubber elasticity and plastic processing properties and can be processed by traditional plastic processing methods such as injection molding and extrusion. TPE has good elasticity and wear resistance. Further, silicone material can also be used. Silicone is a highly active adsorption material with good elasticity and flexibility and good stability to temperature and humidity changes. Further, polyurethane material can also be used. Polyurethane is a porous elastic material with good wear resistance, oil resistance, aging resistance, and good elasticity. Further, rubber material can also be used. Rubber is an elastic material with good elasticity and wear resistance. Rubber can be processed by methods such as vulcanization to make products of various shapes and sizes.

[0033] It can be understood that the release latch 1 made of an elastic material can enhance the durability of the product, extend its service life, and can provide good elasticity to enhance the reset ability of the button 11.

[0034] In some embodiments, a trigger unit 114 is provided on the release top surface of the release portion 113, and a support plate 115 extends from the release bottom surface of the release portion 113 in a direction away from the release top surface. By providing the trigger unit 114, the trigger sensitivity of the button 11 can be improved, and the button 11 experience can be enhanced;

[0035] In some embodiments, the triggering unit 114 has a ramp structure, and the triggering unit 114 and the releasing portion 113 are integrally formed.

[0036] According to another aspect of the present application, as Figure 4 and Figure 5 shown, a conductive tube is also disclosed. The conductive tube 2 includes an inner tube 21, a spliced tube assembly, and the release latch with elastic arms according to any one of the above. The spliced tube assembly includes a first outer tube 22 and a second outer tube 23. The first outer tube 22 and the second outer tube 23 are spliced and sleeved outside the inner tube 21. There is a receiving space 24 between the inner tube 21 and the spliced tube assembly. A first assembly hole is provided on the first outer tube 22, and a second assembly hole is provided on the second outer tube 23. The stabilizing portion 111 cooperates with the first assembly hole, and the releasing portion 113 cooperates with the second assembly hole. The elastic arm 12 is received in the receiving space 24, and the non-connected section of the elastic arm 12 abuts against the inner tube 21.

[0037] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
