Txhawm rau daws qhov teeb meem ntawm cov yeeb nkab hlau uas feem ntau poob ntawm cov chaw tsim kho, peb lub tuam txhab tau koom ua ke cov thev naus laus zis patent CN222731064U los tsim ib tiam tshiab ntawm cov khoom siv tiv thaiv kev poob. Cov khoom no tau txais kev tsim kho tshiab ob-hinged clamping mechanism. Los ntawm kev tsim qauv synchronous locking ntawm clamping phaj ib thiab clamping phaj ob, qhov kev sib txhuam zoo li qub ntawm cov yeeb nkab hlau thiabtus ntsia hlautau nce mus txog 3.2 npaug ntawm cov khoom ib txwm muaj, daws tau tag nrho cov "teeb ​​meem loosening los ntawm cov yeeb nkab hlau deformation". Hauv kev sim ua qauv kev co ntawm kev tsim kho, nws tiv taus 5,000 lub voj voog ntawm kev cuam tshuam yam tsis muaj kev hloov chaw, ntau tshaj qhov tus qauv kev lag luam ntawm 2,000 lub voj voog.

Txhawm rau daws qhov xav tau kev tiv thaiv kev poob ntawm kev ua haujlwm siab, lub fastener tau nruab nrog lub pin zoo li wedge tiv thaiv kev poob. Thaum lub bolt tsis txhob txwm xoob, nws tuaj yeem snap rau hauv qhov kav dej hlau, ua rau muaj lub tshuab xauv thib ob. Qhov kev tsim "double insurance" no tau dhau los ua qhov kev sim ua haujlwm hauv qhov project siab heev hauv Guangzhou: hauv cov xwm txheej uas huab cua convective muaj zog ua rau me ntsis deformation ntawm qee qhovcov scaffolding, tsis muaj ib lub yeeb nkab hlau poob tawm ntawm cov khoom siv tiv thaiv kev poob, ua rau nws tau txais kev qhuas ntawm "lub neej siv sia"los ntawm tus neeg cog lus dav dav.
