Description

Technical Field

[0001] This utility model relates to the field of elastic component installation technology, and in particular to a torsion spring installation mechanism. Background Technology

[0002] Torsion springs, also known as torsion springs, are among the most complex types of springs in terms of design principle. They belong to the category of helical springs. The ends of a torsion spring are fixed to other components. When these components rotate around the spring's center, the spring pulls them back to their initial position, generating torque or rotational force. Torsion springs can store and release angular energy or statically fix a device by rotating a lever arm around the spring's central axis. Torsion springs are often used at the pivot points of lids and caps, allowing the lid to open and unlatch the inner cavity of the box after the lid is unlocked by a switch.

[0003] However, due to the limited space at the pivot point between the lid and the body, and in order for the torsion spring to function, it needs to be fitted onto the pivot. The pivot is rotatably connected to the body, and one end of the torsion spring needs to be fixed to the pivot with bolts, while the other end needs to be connected to the lid. When the end of the torsion spring needs to be aligned with the locking end of the lid, the limited space makes it inconvenient to apply force, and the deformation of the torsion spring will generate a large reaction force, making it difficult to operate and align and fix. This makes the installation of the torsion spring very difficult. Utility Model Content

[0004] The main purpose of this utility model is to provide a torsion spring mounting mechanism, which aims to make the torsion spring easy to install and fix.

[0005] To achieve the above objectives, this utility model proposes a torsion spring mounting mechanism, comprising a locking element and an operating structure:

[0006] One end of the locking device is provided with a locking structure;

[0007] One end of the operating structure is provided with a mounting part facing the locking fastener. The end face of the locking fastener facing away from the locking structure is connected to the mounting part. One end of the mounting part is provided with an operating handle away from the locking structure, and the other end is provided with a limiting part. The orthographic projection of the locking fastener on the operating structure is located between the operating handle and the limiting part.

[0008] In one embodiment of this application, a guide portion is provided at the end of the limiting portion away from the operating handle and away from the end face of the locking fastener, and the height of the guide portion gradually decreases along the direction away from the mounting portion.

[0009] In one embodiment of this application, the end of the guide portion is provided with a limiting block facing the locking fastener, and the limiting block is parallel to the locking structure.

[0010] In one embodiment of this application, the limiting portion has abutting portions protruding from both sides, the abutting portions passing through the limiting block, and the abutting portions are arc-shaped.

[0011] In one embodiment of this application, the end face of the locking structure facing the limiting portion is provided with a mating connection end.

[0012] By adopting the above technical solution, this utility model has the following advantages:

[0013] 1. The locking structure installed on the locking device can be used to install the shaft of the torsion spring to be connected. The shaft can be fixed by locking structures such as slots, snap-fit ​​parts, bolts, and screw holes. At the same time, the locking device itself can be installed on the operating structure through the mounting part. The operating handle can help improve the overall installation efficiency of the torsion spring.

[0014] 2. Torsion springs generally have two ends. One end connects to a rotating shaft, and the other end needs to be connected to a cover, cap, or other structure to ensure the torsion spring can work properly. The rotating shaft is installed on the locking structure and is positioned away from the operating handle. Therefore, the rotating shaft will be at least partially below the limiting part, so that one end of the torsion spring is connected to one side of the limiting part in its natural state. By first fixing the other end of the torsion spring away from the limiting part to the rotating shaft, the end facing the torsion spring can be pried open with a tool or by hand, so that it bypasses the side wall of the limiting part and abuts against the bottom wall of the limiting part. At this time, the torsion spring is in an energy storage state. After fixing the rotating shaft in the designated position with the handle, first connect one end of the torsion spring to the locking part on the cover along the operating structure. Fix the end and the cover with bolts, then loosen the connecting screws of the locking structure and the rotating shaft, and finally remove the operating structure. This method can greatly improve the installation efficiency of the torsion spring.

[0015] 3. After separating the locking structure from the shaft, the damper can be installed on one end of the shaft along the same or similar path as the installation path of the locking structure. This can improve the user experience. The locking device itself can be replaced according to the end structure of the shaft, so that the locking structure can firmly fix the shaft. This structure makes it easy to install and fix the torsion spring, which can effectively improve the operating efficiency. Attached Figure Description

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] Reference Figures 1 to 6 To achieve the above objectives, this utility model proposes a torsion spring mounting mechanism, including a locking member 1 and an operating structure 2. One end of the locking member 1 is provided with a locking structure 11; one end of the operating structure 2 is provided with a mounting part 21 facing the locking member 1. The end face of the locking member 1 away from the locking structure 11 is connected to the mounting part 21. One end of the mounting part 21 away from the locking structure 11 is provided with an operating handle 22, and the other end is provided with a limiting part 23. The orthographic projection of the locking member 1 on the operating structure 2 is located between the operating handle 22 and the limiting part 23.

[0028] The locking structure 11 installed on the locking device 1 can be used to install the shaft of the torsion spring to be connected. The shaft can be fixed by locking structures such as slots, snap-fit ​​parts, bolts, and screw holes. At the same time, the locking device 1 itself can be installed on the operating structure 2 through the mounting part 21. The operating handle 22 can help improve the overall installation efficiency of the torsion spring.

[0029] A torsion spring typically has two ends. One end is connected to a pivot, and the other end needs to be connected to a cover, lid, or other structure to ensure the torsion spring functions properly. The pivot is mounted on the locking structure 11 and is positioned away from the operating handle 22. Therefore, the pivot will be at least partially below the limiting part 23, allowing one end of the torsion spring to be connected to one side of the limiting part 23 in its natural state. By first fixing the other end of the torsion spring away from the limiting part 23 to the pivot, the end facing the torsion spring can be pried open with a tool or by hand, causing it to bypass the side wall of the limiting part 23 and abut against the bottom wall of the limiting part 23. At this time, the torsion spring is in an energy storage state. After fixing the pivot in the designated position using the handle, first connect one end of the torsion spring to the locking part on the cover along the operating structure 2. Secure the end and the cover with bolts, then loosen the connecting screws between the locking structure 11 and the pivot, and finally remove the operating structure 2. This method can greatly improve the installation efficiency of the torsion spring.

[0030] After separating the locking structure 11 from the shaft, the damper can be installed on one end of the shaft along the same or similar path according to the installation path of the locking structure 11, which can improve the user experience. The locking device 1 itself can be replaced according to the end structure of the shaft, so that the locking structure 11 can firmly fix the shaft. This structure makes it easy to install and fix the torsion spring, which can effectively improve the operating efficiency.

[0031] Figure 2 As can be seen, one side of the torsion spring is engaged with the bottom wall of the limiting part 23 by twisting, and the other side of the torsion spring is fixed to the rotating shaft. This allows for very convenient fixing of the rotating shaft. After the rotating shaft is fixed, the torsion spring can be operated on, because the other end of the torsion spring has been locked by the mounting mechanism. With the cooperation of the mounting mechanism, the end of the torsion spring can be directly aligned with the connection of the box cover, which facilitates the fixing of the torsion spring. The installation effect can be seen from [reference needed]. Figure 1 ,and Figure 1 The left side shows the fully installed state, while the right side shows the state where the torsion spring was not successfully installed.

[0032] See also Figures 3 to 4 In one embodiment of this application, a guide portion 24 is provided at the end of the limiting portion 23 away from the operating handle 22 and away from the end face of the locking fastener 1, and the height of the guide portion 24 gradually decreases along the direction away from the mounting portion 21.

[0033] In this application, the guide part 24 is arc-shaped. After one end of the torsion spring is fixed to the rotating shaft, the other end of the torsion spring can pass around the side wall of the limiting part 23 along this arc and abut against the bottom wall of the limiting part 23. This makes it easy to install the torsion spring onto the entire mounting mechanism. The fixed torsion spring and rotating shaft can be installed easily, improving installation efficiency and effectiveness.

[0034] See also Figures 2 to 5 In one embodiment of this application, the end of the guide portion 24 is provided with a limiting block 25 facing the locking fastener 1, and the limiting block 25 is parallel to the locking structure 11.

[0035] The limiting block 25 can extend the guide portion 24 and form a locking position, which can be used to lock one end of the torsion spring, making it easier to install. After the mounting mechanism fixes the rotating shaft, the torsion spring is sleeved on the rotating shaft, with one end fixed to the rotating shaft and the other end fixed by the limiting portion 23. Because the other end of the torsion spring passes through the side wall of the limiting portion 23 and abuts against its bottom wall, and the limiting block 25 is connected to the end of the bottom wall of the limiting portion 23, the limiting block 25 can further limit the torsion spring, preventing the torsion spring end from springing back due to torsional force before the user has operated, thus causing installation failure. The limitation of the limiting block 25 makes the installation operation of the torsion spring easier to achieve and reduces the possibility of failure, improving the user experience.

[0036] See also Figure 5 In one embodiment of this application, the limiting part 23 is provided with abutting parts 26 on both sides, the abutting parts 26 pass through the limiting block 25, and the abutting parts 26 are arc-shaped.

[0037] The protruding arc shape of the abutment part 26 reduces the contact area between the abutment part 26 and the torsion spring, thus reducing friction. This allows the torsion spring end to be better aligned when snapping is required. Furthermore, the arc shape reduces damage caused by friction between the abutment part 26 and the torsion spring end, resulting in a longer service life for the installation mechanism and effectively optimizing the user experience.

[0038] See also Figures 3 to 5 In one embodiment of this application, the end face of the locking structure 11 facing the limiting part 23 is provided with a mating connection end 12.

[0039] The connecting end 12 is used to align the end of the rotating shaft, so that the locking structure 11 can connect the rotating shaft tightly. This helps to lock the rotating shaft and prevents the rotating shaft from coming off the mounting mechanism when the torsion spring is operated, thus avoiding the loss of all previous efforts and effectively improving the user experience.
