Abstract

The utility model discloses a movable cabinet. Except that the movable cabinet comprises a guide way and a cabinet body, the movable cabinet also adopts a lifting resilience damping device, a rotary article rack, and a locking device. The utility model has the advantages of simple structure, convenience and easiness. Any attached device is not needed. Because the lifting resilience damping device is adopted, the user doesn't have a burden feeling suddenly when the cabinet body is under the state of unlocking. Because the locking device is adopted, the weight of the cabinet body and the weight of the articles are used fully, and the friction self locking is realized. Non-stage locking can also be realized, the requirements of the users in different heights can be satisfied.

Description

Movable cabinet

The utility model is a kind of daily living article, promptly a kind of removable cabinet case.

Employed closet or built-in wardrobe mostly are fixed in present dwelling house, the room.Along with the continuous increase of China's population, living conditions are nervous thereupon, therefore can effectively utilize the useful space in room, accessing article easily again, and can improve and beautify living environment and become the problem that people press for solution.A kind of " lift cabinet case " disclosed in Chinese patent 2083430 Qian, this patent except adopt guide rail, guide box is external also support etc. need be housed.

The purpose of this utility model is just for fear of the deficiency of above-mentioned prior art and a kind of removable cabinet case that designs.It need not adopt support, and lifting resilience damping unit also is housed, and its locking device is to utilize the weight of casing and article itself to produce friction self-locking and design.

Concrete solution of the present utility model is that lifting resilience damping unit and locking device are housed on the backboard of cabinet case, and the rotary type article rack is housed in casing.

Below in conjunction with accompanying drawing the utility model is elaborated:

Removable cabinet case mainly is made up of casing 1, guide rail 2.On the backboard 3 of casing lifting resilience damping unit and locking device are installed.Casing can move up and down and fix along guide rail.Casing can be made into multilayer, and is furnished with cover plate 4.When opening, cover plate also can be used as the table top that holds article.Two rotary type article rack 5 can be installed in the casing, this frame be connected with casing also and can relatively rotate by bearing pin.Can place article in the rotary type article rack.

Lifting resilience damping unit adopts two kinds of schemes: first kind of scheme be by bolt 6 with disk spring 7, end cap 8, pulley 9, clockwork spring 10, rubber blanket 11, ratchet 12, tighten nut 14, bearing 15 is installed on the backboard 3, ratchet 13 directly is loaded on the backboard.When with pulling moving casing when moving downward, because steel wire rope 16 articulates on pulley 9 and by directive wheel 17 and guide rail, turn clockwise so drive pulley after the steel wire rope tension, tighten the clockwork spring 10 on the pulley simultaneously.Because pulley turns clockwise, and makes the just in time stuck ratchet 12 of ratchet 13, therefore between pulley-rubber blanket-ratchet, produce the sliding friction damping torque.The big I of damping torque tightens nut 14 according to Item Weight in the case and user's feel by adjustment and realizes that the degree of tightness that tightens nut directly influences the degree of tightness of disk spring, thereby obtains different rubbing surface normal pressures.When the casing that holds in the palm moved upward, the clockwork spring resilience drove pulley simultaneously and tightens up steel wire rope.This moment, ratchet was a released state.Because the stiction effect between pulley-rubber-ratchet makes ratchet with the pulley turning anticlockwise.Be casing when moving upward, this device is given full play to the effect of clockwork spring and is not played any damping action.

Second kind of scheme adopts installs extension spring or stage clip 18 in guide rail, this guide rail can embed in the wall, connects guide rail and casing with connector 19 again.Casing backboard both sides are fixed with friction ratchet gear 20 and are pressed on the guide wall, and it can only one-directional rotation.When pulling down casing with hand, the spring in the guide rail is stretched or compressed.This moment, ratchet was pressed on the guide wall by the effect of spring 21, therefore made to produce the sliding friction damping between guide rail-friction ratchet gear.When casing moved upward, extension spring or stage clip 18 released energy, and friction ratchet gear release simultaneously also scrolls up along guide rail.Give full play to the rebound effect of guide rail medi-spring 21 this moment.

Locking device of the present utility model is a weight of utilizing casing and article itself, realizes friction self-locking, thereby makes casing realize locking, promptly stepless locking at the arbitrary height of guide rail.Locking device adopts two kinds of schemes.First kind of scheme is at backboard stop hoof 22, throw-out lever 23, sleeve 24, extension spring 25 to be installed.With reference to Fig. 8, pin joint 0 place is connected with extension spring 25 and 23, two throw-out levers of throw-out lever pass from sleeve, and sleeve is installed on the backboard, and the two ends of throw-out lever connect stop hoof 22, and the stop hoof is close on the guide wall.When pulling the moving upper and lower motion of casing, press locking switch, switch drives pin joint and moves upward, and leaves guide rail thereby make throw-out lever drive the stop hoof, is released state at this moment.When unclamping locking switch, pin joint moves downward under the effect of extension spring 25, and throw-out lever is pressed on the stop hoof on the guide rail.Because sleeve and casing are hinged, so the gravity of casing just acts on the throw-out lever, force throw-out lever further the stop hoof to be pressed on the guide rail.This locking device can be realized stepless locking.

Second kind of scheme is that the side at guide rail is equipped with support 26, roller 27, door bolt core 28, spring 29, end cap 30, lever 31, connecting rod 32, and support links to each other with backboard.The door bolt core connects together guide rail, roller, lever.Have several locating holes on the guide rail.In the time of the upper and lower motion of casing, press locking switch, the pin joint 0 of two connecting rods 32 is moved down, cause connecting rod to drive lever 31 and drive door bolt core 28 compression springs 29 and withdraw from from the locating hole 33 of guide rail, be released state this moment.When unclamping locking switch, the door bolt core makes the door bolt core insert another locating hole on the guide rail again and obtain lock-out state under the effect of spring tension.

Use the utility model is simple in structure, and is convenient and easy.Owing to adopted damping unit, both made the interior article of case overweight, and under the situation of locking device release, the unlikely user of causing has unexpected heavy burden and holds in the palm the incessantly sensation of casing, moreover the size of damping force also can arbitrarily have been adjusted.Owing to adopted locking device, make full use of the weight of casing and article itself, realize friction self-locking, thereby make casing realize locking at the arbitrary height of guide rail, satisfied different height users' demand.
