Description

Technical Field

[0001] This utility model belongs to the field of mechanical assembly technology, and in particular relates to a button movable buckle. Background Technology

[0002] The detachable connection between the center shaft and the base shell is one of the core assembly requirements of various equipment (such as home appliances, industrial machinery or small electronic devices). The rationality of its connection structure directly affects the product's assembly efficiency, maintenance convenience and service life. The center shaft is generally installed vertically in the middle of the tripod.

[0003] Currently, the connection between the central shaft and the base shell generally uses threaded connection or rigid snap-fit ​​connection. Both of these connection methods have certain technical drawbacks in practical applications:

[0004] For threaded connections, screwdrivers or wrenches are needed to align and tighten them one by one during assembly, and the same reverse operation is required during disassembly. This method is not only cumbersome and time-consuming, but it will also severely restrict production efficiency and increase labor costs in mass production assembly scenarios.

[0005] While rigid snap-fit ​​connections do not require tools during assembly, they require external force to pry open during unlocking. This can easily lead to plastic deformation, breakage, or wear of the snap-fit ​​cantilever beam structure. After repeated disassembly and assembly, the connection strength decreases significantly, making it prone to loosening or falling off, which seriously affects the reliability of the product connection.

[0006] Therefore, in view of the above situation, there is an urgent need to develop a button-activated latch to overcome the shortcomings in current practical applications. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide a button movable latch to solve the problems in the background technology mentioned above.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A button-operated latch includes a base shell whose shape is adapted to the shape of a central shaft, which is vertically mounted in the middle of a tripod. One end of the base shell is designed as an open structure. A fixing post is vertically fixed inside the base shell. Corresponding through holes are formed in the radial directions of both the base shell and the fixing post. Lateral notches are formed on two side walls symmetrically arranged along the fixing post on the base shell. The latch also includes:

[0010] The movable column has one end slidably connected to the through holes on the bottom shell and the fixed column, and the other end of the movable column extends to the outside of the bottom shell and cooperates with the snap hole opened on the side wall of the central axis.

[0011] An elastic pressing component is installed at one end of the opening structure on the bottom shell. One end of the elastic pressing component is slidably engaged with the lateral notch and the insertion hole in the middle of the movable column. The elastic pressing component drives the movable column to restore and release the engagement state with the locking hole by pressing inside the bottom shell.

[0012] As a further technical solution of this utility model, the elastic pressing assembly includes a pressure sleeve, a button, a pin, and a spring. The pressure sleeve is slidably installed at one end of the opening structure on the bottom shell. A spring is installed between the bottom of the pressure sleeve and the fixed post. An inclined guide groove is provided on the side of the pressure sleeve near the lateral notch, which slides with both ends of the pin. The middle part of the pin slides with the insertion hole opened in the middle of the movable post. The top of the pressure sleeve extends to the outside of the bottom shell and is fixedly connected to the button.

[0013] As a further technical solution of this utility model, the layout trajectory of the inclined guide groove is perpendicular to the movement trajectory of the movable column, the inclined guide groove is laid out along the axial direction of the bottom shell, and the movable column moves along the radial direction of the bottom shell.

[0014] As a further technical solution of this utility model, the length of the pin is less than the straight-line distance between the lateral notches on both sides of the bottom shell.

[0015] As a further technical solution of this utility model, a guide slope is provided at one end of the movable column extending outside the bottom shell, and the guide slope is slidably engaged with the card hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The elastic pressing component changes the radial position of the movable column on the bottom shell by pressing it inside the shell, thereby causing the movable column to return to or release its engagement with the locking hole. The elastic design of the elastic pressing component allows the movable column and the locking hole of the central shaft to form a tight fit, effectively solving the problem of accidental unlocking caused by vibration or collision of traditional buckles. This creates a quick-disassembly connection between the bottom shell and the central shaft, allowing for unlocking or locking of the bottom shell and central shaft with one hand without tools. Compared with traditional threaded connections or rigid buckle connections, this significantly improves the efficiency of disassembly and assembly of the bottom shell and central shaft, making it suitable for batch assembly or high-frequency maintenance scenarios and significantly reducing labor and time costs.

[0018] The movable column and elastic pressing component are both integrated inside the bottom shell, so there are no extra protruding parts on the bottom shell. Compared with traditional split buckles, the overall size is smaller, which can flexibly adapt to narrow installation scenarios and improve the flexibility and practicality of product structure design.

[0019] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 5 As shown, a button-moving latch provided as an embodiment of this utility model includes a bottom shell 3, the outer dimensions of which are adapted to the outer dimensions of a central shaft 2. The central shaft 2 is vertically installed in the middle of a tripod 1. One end of the bottom shell 3 is designed as an open structure. A fixing post 31 is vertically fixed inside the bottom shell 3. Corresponding through holes 32 are provided in the radial directions of both the bottom shell 3 and the fixing post 31. Lateral notches 33 are provided on two side walls symmetrically arranged along the fixing post 31 on the bottom shell 3. The latch also includes:

[0029] The movable column 5 has one end slidably connected to the through hole 32 on the bottom shell 3 and the fixed column 31 respectively, and the other end of the movable column 5 extends to the outside of the bottom shell 3 and cooperates with the snap hole 21 opened on the side wall of the central shaft 2.

[0030] The elastic pressing component 4 is installed at one end of the opening structure on the bottom shell 3. One end of the elastic pressing component 4 slides in engagement with the lateral notch 33 and the insertion hole 52 in the middle of the movable column 5. By pressing within the bottom shell 3, the elastic pressing component 4 can change the radial position of the movable column 5 on the bottom shell 3, thereby causing the movable column 5 to return to or release its engagement with the locking hole 21. Furthermore, the elastic design of the elastic pressing component 4 allows for a tight fit between the movable column 5 and the locking hole 21 of the central shaft 2, effectively solving the problem of accidental unlocking caused by vibration or collision in traditional buckles. The bottom shell 3 and the central shaft 2 form a quick-disassembly connection structure, which can be unlocked or locked with one hand without tools. Compared with traditional threaded or rigid buckle connection structures, it can effectively improve the disassembly and assembly efficiency of the bottom shell 3 and the central shaft 2, adapt to batch assembly or high-frequency maintenance scenarios, and significantly reduce labor and time costs. Moreover, the movable column 5 and the elastic pressing component 4 are integrated inside the bottom shell 3, so there are no extra protruding parts on the bottom shell 3. Compared with traditional split buckles, the overall size is smaller, which can flexibly adapt to narrow installation scenarios and improve the flexibility and practicality of product structure design.

[0031] like Figures 3 to 5 As shown, in a preferred embodiment of the present invention, the elastic pressing assembly 4 includes a pressure sleeve 41, a button 42, a pin 44, and a spring 45. The pressure sleeve 41 is slidably mounted on one end of the opening structure on the bottom shell 3. The spring 45 is installed between the bottom of the pressure sleeve 41 and the fixed post 31. An inclined guide groove 43 is provided on the side of the pressure sleeve 41 near the lateral notch 33, which slides with both ends of the pin 44. The middle part of the pin 44 slides with the insertion hole 52 opened in the middle of the movable post 5. The top of the pressure sleeve 41 extends to the outside of the bottom shell 3 and is fixedly connected to the button 42.

[0032] The inclined guide groove 43 is laid out perpendicular to the moving trajectory of the movable column 5, that is, the inclined guide groove 43 is laid out along the axial direction of the bottom shell 3, and the movable column 5 moves along the radial direction of the bottom shell 3.

[0033] The two ends of the pin 44 abut against the two lateral notches 33, which can effectively install the pressure sleeve 41 into the bottom shell 3 and ensure that the spring 45 between the pressure sleeve 41 and the bottom shell 3 is in a compressed state, forming an elastic connection structure between the bottom shell 3 and the pressure sleeve 41. In the initial state, the pin 44 cooperates with the right end of the inclined guide groove 43. At this time, the movable column 5 is in the extended state and cooperates with the locking hole 21, avoiding accidental unlocking caused by non-human operation such as vibration and collision, and ensuring connection safety.

[0034] When button 42 moves the pressure sleeve 41 inside the bottom shell 3, the pressure sleeve 41 further compresses the spring 45. At the same time, the pressure sleeve 41 drives the pin 44 to move from the right end to the left end through the inclined guide groove 43. The pin 44 and the inclined guide groove 43 cooperate to drive the movable column 5 to move radially towards the inside of the bottom shell 3, so that the movable column 5 is released from the engagement state with the locking hole 21, thereby realizing the separation of the bottom shell 3 and the central shaft 2.

[0035] When it is necessary to restore the engagement state between the movable column 5 and the locking hole 21, release button 42. Spring 45 drives the pressure sleeve 41 to move outward through its own elastic force. The pressure sleeve 41 drives the pin 44 to move from the left and right ends to the right end through the inclined guide groove 43. The engagement of the pin 44 and the inclined guide groove 43 can drive the movable column 5 to move radially outward in the direction of the bottom shell 3, so that the movable column 5 restores the engagement state with the locking hole 21, thereby realizing the quick connection between the bottom shell 3 and the central shaft 2.

[0036] The length of the pin 44 is equal to or slightly less than the straight distance between the lateral notches 33 on both sides of the bottom shell 3. Under the premise that the bottom shell 3 can slide freely in the central shaft 2, it can effectively abut against the lateral notches 33, which not only ensures the stability of the elastic connection between the pressure sleeve 41 and the bottom shell 3, but also avoids interference between the pin 44 and the inner wall of the central shaft 2, ensuring that the bottom shell 3 slides smoothly in the central shaft 2.

[0037] like Figures 3 to 5 As shown, in a preferred embodiment of this utility model, the end of the movable column 5 extending outside the bottom shell 3 is provided with a guide slope 51. The guide slope 51 is slidably engaged with the locking hole 21. The design of the inclined end face can reduce the external resistance encountered when the movable column 5 is connected to the locking hole 21, disperse the contact stress during insertion, and the pin 44 and the inclined guide groove 43 are in surface contact sliding, avoiding connection failure caused by local force concentration, improving the connection success rate of the movable column 5 and the locking hole 21, and also reducing the wear rate of the movable column 5 and extending its service life.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
