Description

Memory bank reinforcing apparatus Technical Field The invention belongs to the technical field of electronic equipment accessories, and particularly relates to a memory bank reinforcing device. Background The memory bank is an indispensable core memory component in electronic equipment such as a server, industrial control equipment and the like, is mainly used for storing and transmitting various data in the running process of the equipment, and the connection stability between the memory bank and a main board directly determines the running efficiency and reliability of the electronic equipment. With the development of devices such as a server and the like towards high storage and high computation power, a single device is usually required to install a plurality of memory banks to meet storage requirements, and the problem of synchronous reinforcement of the plurality of memory banks is also highlighted. In practical application, devices such as a server often need to run for a long time under complex working conditions such as vibration, impact and the like, if a memory strip lacks reliable reinforcement measures, the problems such as loosening and offset are very easy to occur, and further serious consequences such as poor contact between the memory strip and a main board, data transmission interruption, equipment downtime and even hardware damage are caused, so that the memory strip is effectively reinforced, and especially the synchronization and stable reinforcement of a plurality of memory strips are realized, so that the method becomes a key for guaranteeing the long-term reliable operation of the device. At present, various implementation modes for strengthening memory strips exist in the industry, but the modes all face corresponding technical problems, and the implementation modes are as follows: The first is a single-buckle structure of the main board, which is the most common reinforcement mode. The main board is provided with independent buckles at two ends of each memory bar, the memory bars are clamped by the buckles to realize fixation, but the mode can only be operated singly, the memory bars are required to be installed one by one, the efficiency is low, the stress consistency of each memory bar is difficult to ensure, meanwhile, the main board lacks of elastic buffering, the vibration resistance is weak, and the buckles are easy to loosen after long-term use. The second kind is a metal fixed frame structure, which aims to solve the problem of synchronous reinforcement of a plurality of memory banks. The structure adopts the rigid metal material to make the integral frame, covers and fixes a plurality of memory strips, simplifies the installation operation, realizes synchronous reinforcement, but the rigid metal material can not play the role of elastic buffer, is easy to transfer vibration, can not adapt to the dimensional tolerance and the expansion and contraction requirement of the memory strips, and is easy to loose after long-term use. And the third is an auxiliary reinforcing structure of the elastic rubber pad, which is mainly used for improving vibration resistance. According to the structure, the elastic rubber pad is additionally arranged between the memory strips and the buckle to buffer vibration and reduce rigid collision, but only the part of a single memory strip can be optimized, and the integral synchronous reinforcement of a plurality of memory strips cannot be realized. Based on the defects of the prior art, the memory bar reinforcing device capable of realizing synchronous reinforcement of a plurality of memory bars and simultaneously having elastic buffering and reliable locking functions can effectively prevent the memory from loosening caused by vibration and impact, and has important significance. Disclosure of Invention The invention aims to provide a memory bank reinforcing device, which is used for remarkably improving the technical problems that the existing memory bank reinforcing mode cannot achieve synchronous reinforcement, elastic buffering and high-temperature vibration working condition adaptation, realizing synchronous positioning and stable reinforcement of a plurality of memory banks, simultaneously having good elastic buffering, temperature resistance, wear resistance and fatigue resistance, effectively buffering vibration impact in the running process of equipment such as a server, adapting to the high-temperature working environment of the equipment and meeting the long-term reliable running requirements of the electronic equipment such as the server. The aim of the invention is realized by the following technical scheme: The memory bar reinforcing device comprises a U-shaped frame structure, wherein a plurality of accommodating grids which are matched with memory bars in a one-to-one correspondence manner are penetrated on a middle plate of the U-shaped frame structure, an elastic clamping part is integrally formed on the inner side wall of each
