That is, in the fixing apparatus for fixing the slide rail disposed at both sides of the drawer, the drawer in which the substance is accommodated to increase the weight is slid so that the load applied in facing inward directions is moved, and thus, a torsional load is generated at a fixing apparatus fixing position of the support bars according to movement of the load.

Accordingly, the force is applied to the fixing apparatus installed in the horizontal direction to reduce the fixing force and generate movement, and the fixing force of the fixing apparatus is weakened due to continuous movement to be deformed and separated therefrom.
  • the conventional slide fixing apparatus is conventionally installed in plural at positions fixed to the pair of support bars in the horizontal direction, respectively, needs of the fixing apparatus are increased to increase the manufacturing cost, and a task of coupling each fixing apparatus to the support bars cannot be easily performed.
  • the fixing apparatuses since the plurality of fixing apparatuses are press-fitted to the support bars when the pair of support bars are fixed to the slide rails, a large amount of force is applied upon the mounting.

  • the stress is further concentrated on positions of the connecting bars 42 of the pair of support bars 41 , which are ends in which an opening state and a closing state of the shelf 50 are maintained, and positions of the extension bars 45 connected to the corner portions 44 .
  • the pair of support bars 41 are fixed by the support units 210 and the support fixing units 220 , and the torsional stress generated by surrounding and fixing the pair of support bars 41 , the connecting bars 42 and the extension bars 45 are effectively distributed in a state in which the pair of support bars 41 are connected to each other, and thus damage and deformation due to the torsional stress can be prevented to increase the lifespan.
  • the elastic bodies 226 protrude from the insertion fixing pieces 222 facing each other in the direction of the fixing spaces 223 , and are partially connected to the insertion fixing pieces 222 to be moved by elasticity.
  • the elastic bodies 226 protrude in the direction of the fixing spaces 223 to be integrally formed with the insertion fixing pieces 222 while partially connected by the bent grooves 225 of the insertion fixing pieces 222 .
  • the elastic bodies 226 are moved in the direction of the insertion fixing pieces 222 by elasticity when the pair of support bars 41 are inserted, and when the pair of support bars 41 are inserted after movement, the elastic bodies protrude in the direction of the fixing spaces 223 to hook and fix the pair of support bars 41 .
  • FIG. 16 is a use state view showing a state in which the slide rail fixing apparatus of FIG. 11 is installed.
  • the fixing bars 46 are formed in plural at both side surfaces of the main body 40 , and the pair of support bars 41 are arranged in plural according to the number of shelves 50 .
  • the connecting bars 42 connecting the support bars 41 are formed at one sides of the pair of support bars 41 , and the protrusions 43 protruding to be fixed to the fixing bars 46 are formed at one sides of the pair of support bars 41 .
  • the extension bars 45 bent in the direction of the main body 40 and connected to the corner portions 44 are formed at the other side ends of the pair of support bars 41 , and the extension bars 45 are fixed to the fixing bars 46 . Accordingly, the pair of support bars 41 are respectively fixed to the fixing bars 46 by the protrusions and the extension bars 45 connected to the corner portions 44 .
  • the connecting bars 42 are inserted into the support spaces 212 opened toward the other side and defined by the support protrusions 211 b protruding from one sides of the support bodies 211 a in the direction of the pair of support bars 41 and the support fixing bodies 211 c protruding from ends of the support protrusions 211 b in the direction of the support bars 41 to the other side.
  • the pair of support bars 41 are inserted into the fixing spaces 223 formed between the insertion fixing pieces 222 facing each other and enabling insertion of the pair of support bars 41 of the support fixing bodies 221 .
  • the corner portions 44 are inserted into the side surface bodies 224 a protruding from the insertion fixing pieces 222 facing each other in the other side direction, the side surface support members 224 b protruding from ends of the side surface bodies 224 a toward the fixing spaces 223 in facing directions, and the side surface extension bodies 224 c protruding from ends of the side surface support members 224 b in the one side direction.
  • the extension bars 45 connected after insertion of the corner portions 44 are inserted inward. That is, when the pair of support bars 41 are inserted into the fixing spaces 223 , the extension bars 45 are simultaneously inserted into the side surface fixing pieces 224 with one sides open and the others surrounded. Accordingly, the extension bars 45 connected to the corner portions 44 can be fixed to the pair of support bars 41 .
  • the protruding elastic bodies 226 are pressed to elastically move in the direction of the insertion fixing pieces 222 to be easily inserted. After the insertion, the elastic bodies 226 protrude in the direction of the fixing spaces 223 facing each other, fixing the pair of fixing bars 46 .
  • the extension bars 45 connected to the pair of support bars 41 by the corner portions 44 are fixed to connect the pair of support bars 41 to the support fixing bodies 221 , increasing the fixing force.
  • the support bodies 211 a are moved in the direction of the pair of support bars 41 , and both outer sides of the pair of support bars 41 are brought in contact with the support projections 213 projecting from the support members 211 to be supported at their positions, preventing movement. Accordingly, when the slide rails are fixed by the support fixing units 220 , the support members 211 are moved and the pair of support bars 41 are supported by the support projections 213 . As a result, the connecting bars 42 and the pair of support bars 41 inserted into the support spaces 212 are simultaneously supported to increase the support force.
  • the connecting bars 42 and the pair of extension bars 45 formed at both ends of the pair of support bars 41 are fixed by the support fixing apparatuses 200 and the pair of support bars 41 are connected to each other at both sides, preventing movement thereof and preventing damage and deformation by effectively distributing the torsional stress generated due to movement of the shelf 50 .
