Description

Technical Field

[0001] This utility model relates to the field of drum spring installation technology, specifically to an internal compression fitting mechanism for drum springs. Background Technology

[0002] A drum spring is a mechanical part, belonging to the spring family, specifically a drum-shaped spring. It gets its name from its drum-like shape and is generally used as a compression spring, commonly found in the fixed end of electrical connectors. Most are machined from highly conductive, elastic copper alloys, and their surfaces are silver- or gold-plated to achieve low contact resistance and corrosion resistance. The drum spring inside the connector's metal socket ensures effective contact with the pins for current transmission; the insertion and removal of the pins within the drum spring controls the connection and disconnection of the connector.

[0003] When installing drum springs, workers typically use tools such as needle-nose pliers to manually clamp and press the drum spring from multiple angles to retract it, while also pressing its top to move it into the installation position. This requires constant adjustment of the clamping and pressing position, resulting in slow installation efficiency and increased workload for workers. To address this, we propose an internal retraction and pressing mechanism for drum springs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an internal retraction pressing mechanism for drum springs, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an internal compression fitting mechanism for drum springs, comprising a mounting block, wherein a first adjustment groove is provided inside the mounting block, a first adjustment mechanism is provided inside the first adjustment groove, two corresponding first connecting rods are fixedly connected to the bottom of the first adjustment mechanism, a first threaded head is threaded inside the first connecting rod, a second connecting rod is fixedly connected to the bottom of the first threaded head, and a clamping head is fixedly connected to the bottom of the second connecting rod; a second adjustment groove is provided inside the mounting block, a second adjustment mechanism is provided inside the second adjustment groove, a third connecting rod is fixedly connected to the bottom of the second adjustment mechanism, a second threaded head is threaded inside the third connecting rod, a fourth connecting rod is fixedly connected to the bottom of the second threaded head, and a positioning clamp is fixedly connected to the bottom of the fourth connecting rod.

The bidirectional lead screw is rotatably connected to the inside of the first adjusting groove via bearings, and the two first adjusting blocks are slidably connected to the inside of the first adjusting groove. The bidirectional lead screw passes through the two first adjusting blocks and is threadedly connected to them. The first connecting rod is fixedly connected to the bottom of the first adjusting blocks.

[0007] Preferably, one end of the bidirectional lead screw extends to the outside of the mounting block and is fixedly connected to a first throttle. The first throttle has a plurality of first insertion slots inside, and a first insertion rod is inserted into the first insertion slot. The mounting block has a first magnetic groove inside, and a first magnetic block is fixedly connected to one end of the first insertion rod.

[0011] Preferably, the positioning clamp is made of a resilient metal material.

[0012] This utility model provides an internal compression fitting mechanism for drum springs, which has the following beneficial effects:

[0013] 1. This internal compression fitting mechanism for drum springs uses two clamping heads to engage the outer side of the drum spring. Rotating the first throttle causes the bidirectional lead screw to rotate, which in turn causes two first adjusting blocks to slide accordingly. This, in turn, causes the two clamping heads to move accordingly via two first connecting rods and a second connecting rod, thus retracting both sides of the drum spring. This facilitates moving the drum spring to the installation position. Then, a tool is manually used to block one side of the drum spring, and the two clamping heads are pulled out from the outside of the drum spring, releasing the constraint on the drum spring and allowing it to rebound and reset, thereby completing the installation of the drum spring and improving installation efficiency.

[0014] 2. The internal retraction pressing mechanism for drum springs, through the cooperation of the second adjusting groove, the second adjusting block, the threaded rod, and the second rotary handle, allows for the adjustment of the positions of the third connecting rod, the fourth connecting rod, and the positioning clamp according to different specifications of drum springs, thereby positioning the two clamping heads. Through the cooperation of the first connecting rod, the first threaded head, the third connecting rod, and the second threaded head, the second connecting rod, the clamping head, the fourth connecting rod, and the positioning clamp can be replaced according to different specifications of drum springs, improving the convenience of using the internal retraction pressing mechanism for drum springs.
