Abstract
Description
Technical Field
[0001] This invention relates to SSPC boards, and more particularly to an SSPC board puller structure. Background Technology
[0002] With the increasing use of SSPC boards and the growing demand for modularity in various airborne equipment, the modular design for securing SSPC boards is becoming increasingly urgent. How to quickly secure and disassemble SSPC boards has become a critical technical problem to be solved. Currently, existing SSPC boards are equipped with pullers, but these pullers lack a self-locking function. The gap between the puller and the SSPC board can lead to damage from noise and mechanical vibration, reducing product reliability. Summary of the Invention
[0003] The purpose of this invention is to solve the problem that the puller of existing SSPC boards lacks a self-locking function, and to provide a new type of SSPC board puller structure.
[0004] To achieve the above objectives, the present invention provides a technical solution: an SSPC board puller structure, comprising: a puller handle. The puller handle is symmetrically located at two apex positions of the cold plate portion of the SSPC board. The puller handle has a first handle end and a second handle end opposite to each other along the handle length direction. The first handle end is rotatably disposed on the SSPC board. The second handle end has a handle locking tongue that displaces along the handle length direction. The SSPC board has a cold plate locking hole portion corresponding to the handle locking tongue portion. When the handle locking tongue portion enters the cold plate locking hole portion, the puller handle is in a locked state, and when the handle locking tongue portion leaves the cold plate locking hole portion, the puller handle is in an unlocked state. A compression torsion spring is provided between the first handle end and the cold plate portion of the SSPC board, the compression torsion spring being used to lift the puller handle in the unlocked state and to self-lock the puller handle in the locked state.
[0005] As a preferred embodiment of the SSPC board puller structure, the puller handle is equipped with a compression spring, which abuts against the handle locking tongue and is used to keep the handle locking tongue in the locked state inside the cold plate locking hole.
[0006] As a preferred embodiment of the SSPC board puller structure, the puller handle is equipped with a handle slider, which is located outside the puller handle and can drive the handle locking tongue to move.
[0007] As a preferred embodiment of the SSPC board puller structure, the puller handle has a handle groove extending along the length of the handle, the handle slider is inside the handle groove and can slide along the handle groove, and the handle slider is fixedly connected to the handle locking tongue. The puller works by sliding the handle slider.
[0008] Compared with the prior art, the beneficial effects of the present invention are at least as follows: when the puller handle is locked, the compression torsion spring pushes against the puller handle, and the handle locking tongue presses tightly against the cold plate locking hole, thereby realizing the puller's self-locking and avoiding noise and vibration damage caused by loosening.

[0013] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. It should be noted that these descriptions of embodiments are intended to aid in understanding the invention and do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0014] See Figures 1 to 2 The figure shows a structure for an SSPC board puller. The SSPC board puller structure includes a puller handle 1, etc. The puller handle 1 is symmetrically located at two apex positions of the cold plate portion 100 of the SSPC board.
[0015] See also Figure 3 and Figure 4 The puller handle 1 has a first handle end 11 and a second handle end 12 that are opposite each other along the handle length direction. The first handle end 11 is rotatably disposed on the cold plate portion 100 of the SSPC board. In a specific implementation, the first handle end 11 is connected to the cold plate portion 100 of the SSPC board via a rotating shaft 111, the rotating shaft 11 being perpendicular to the plane of the cold plate portion 100 of the SSPC board.
[0016] The second end 12 of the handle has a handle latch 121 that is displaceable along the length of the handle. The cold plate portion 100 of the SSPC board has a cold plate locking hole 101 corresponding to the handle latch 121. When the handle latch 121 enters the cold plate locking hole 101, the puller handle 1 is in a locked state. When the handle latch 121 leaves the cold plate locking hole 101, the puller handle 1 is in an unlocked state.
[0017] A compression torsion spring 13 is located between the first end 11 of the handle and the cold plate portion 100 of the SSPC board. The compression torsion spring 13 lifts the puller handle 1 in the unlocked state. When the puller handle 1 is locked, the compression torsion spring 13 self-locks the puller handle 1 to prevent noise and vibration damage caused by loosening. In specific implementation, one end of the compression torsion spring 13 is fixed. The other end of the compression torsion spring 13 abuts against the puller handle 1. When the handle locking tongue 121 leaves the cold plate locking hole 101, the puller handle 1 is unlocked, the elastic force of the compression torsion spring 13 is released, and the compression torsion spring 13 lifts the puller handle 1. At this time, the operator can pull out the SSPC board as a whole by holding the puller handle 1.
[0018] Preferably, the puller handle 1 is equipped with a compression spring 14. The compression spring 14 abuts against the handle locking tongue 121. The compression spring 14 is used to hold the handle locking tongue 121 in a locked state inside the cold plate locking hole 101. When the external force acting on the handle locking tongue 121 is greater than and in the opposite direction to the elastic force of the compression spring 14, the handle locking tongue 121 begins to displace, moving away from the cold plate locking hole 101. In a specific implementation, the compression spring 14 and the handle locking tongue 121 are in the same internal cavity and arranged along the length of the handle. The compression spring 14 is fixed to the end of the handle locking tongue 121 away from the cold plate locking hole 101. In a specific implementation, the compression spring 14 can be made of 0Cr19Ni9 stress-relieved tempered steel wire.
[0019] Preferably, the puller handle 1 is equipped with a handle slider 15. The handle slider 15 is located outside the puller handle 1. The handle slider 15 can move the handle latch 121. In a specific implementation, the puller handle 1 has a handle groove 10 extending along the length of the handle. The handle slider 15 is located inside the handle groove 10 and can slide along the handle groove 10. The handle slider 15 is fixedly connected to the handle latch 121 by screws 16. By sliding the handle slider 15, the purpose of moving the handle latch 121 is achieved. In a specific implementation, the surface of the handle slider 15 is provided with knurled stripes for easy finger operation and to prevent slippage.
[0020] Preferably, the puller handle 1 is equipped with an arrow mark indicating the unlocking direction to prompt the operator on the unlocking direction.
[0021] The above description merely illustrates embodiments of the present invention and is quite specific and detailed; however, it should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
