Abstract

A position limit mechanism of a cabinet frame sliding door comprises a moveable door frame and a cabinet body frame matched with the door frame, wherein the door frame is provided with frame edges propped against the side wall of the cabinet body frame and arranged along the vertical direction, and the upper and lower parts of the cabinet body frame are respectively provided with two tracks for the door frame to slip. The position limit mechanism is characterized in that a limited block with convex curved surface is arranged on the inside wall of each track, the limited block is arranged at the end part near the track, and a concave curved surface matched with the limited block is arranged on the surface of each frame edge. Compared with the prior art, in the utility model, the concave curved surface is arranged on the frame edge of the door frame, and the convex limited block matched with the curved surface is arranged on the track, as the door frame slips along the track so as clamp the limited block into the curved surface, the raised parts on the two sides of the curved surface block rightly the two sides of the limited block, therefore, the limited block achieves the function of limiting relative to a sliding door, and can prevent the sliding door from opening automatically.

Description

Tank bracket moves the position-limit mechanism of door

Technical field

The utility model relates to a kind of position-limit mechanism, and particularly a kind of tank bracket moves the position-limit mechanism of door.

Background technology

On tank bracket, install and move door, can be so that the article in the protection tank bracket be subjected to extraneous interference and destruction, particularly some valuable historical relics; cannot contact with air for a long time, need be waterproof and dampproof, therefore; usually, all be provided with able to turn on or off door moving structure before being used to deposit the tank bracket body of historical relic.

Because historical relic is very precious, therefore the requirement of depositing is relatively harsher, and the gate open of moving of the prior art often all only is provided with locomotive function, and certain position limiting structure is not set, some position limiting structure move door because complex structure is installed trouble, practicality is not strong.In order to guarantee to move the reliability that door is closed, and reduce vibration at closing time simultaneously, need move door and be provided with and imitate the ground position limiting structure,, prevent to move door and open automatically to guarantee moving door closing reliable location, back.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of to reduce vibration at closing time and can prevent that the framework of opening automatically from moving the position-limit mechanism of door at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this tank bracket moves the position-limit mechanism of door, the cabinet body frame that includes doorframe movably and cooperate with this doorframe, described doorframe has the edge that the sidewall with described cabinet body frame offsets and vertically is provided with, the upper and lower of described cabinet body frame has respectively can be for the track of described doorframe slippage, it is characterized in that: described track inside wall is provided with the surface and is the limited block of outer convex surface, the end that this limited block closes on described track is provided with, and described edge is formed with the inner sunken face that can match with described limited block on the surface, when described doorframe along slide to buttoned-up status, described limited block snaps in the indent of described edge and goes in the curved surface.

In order to improve spacing reliability further, as preferably, can adopt the spacing structure in both sides, be that described edge is formed with described inner sunken face respectively on outer surface and inner surface, correspondingly, described track with two side that described edge cooperates on be respectively arranged with described limited block.So, doorframe all is provided with inner sunken face at the front side and the rear side of edge, and track also is respectively arranged with a limited block on two sidewalls, in the time of can guaranteeing that doorframe moves to the limited block place of track, the front and back side of doorframe realizes the location by the mode that limited block and inner sunken face cooperate simultaneously, and the location more accurately and reliably.

Consider the convenience of integral aesthetic property and processing, described inner sunken face can form a groove that vertically runs through for the vertical setting along described edge.So doorframe forms an arc groove that vertically runs through respectively in the front and back of frame side, the limited block on the track just in time can snap among this groove.

Compared with prior art, advantage of the present utility model is: the edge of doorframe is provided with the curved surface of indent, correspondingly, be provided with the evagination limited block that can cooperate with curved surface in orbit, when doorframe made that along the track slippage limited block snaps in the curved surface, the both sides of limited block were just in time blocked at high position of rising, curved surface both sides, so, limited block just plays certain barrier force with respect to moving door, plays position-limiting action, can prevent to move door and open automatically; In addition, the cooperation of limited block and curved surface can also be played the damping buffering effect, can reduce vibration at closing time, avoids the historical relic in the tank bracket is damaged.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 5, be specific embodiment of the utility model, wherein, Fig. 1 is the structural representation of present embodiment tank bracket, this tank bracket includes two cabinet body frames 1 of fanning doorframe 2 movably and cooperating with doorframe, and the both sides of each doorframe 2 have the edge 21 that can offset with the sidewall of cabinet body frame 1 and vertically be provided with, and cabinet body frame 1 has can be for the track 11 of doorframe 2 slippages, the crossbeam 22 of doorframe 2 is contained in the track 11 just and can slides along track 11, referring to Fig. 2;

Track 11 is embedded with the rigidity limited block 3 of an evagination on inside wall, referring to Fig. 4, limited block 3 is provided with near the end of track 11, when doorframe 2 when track 11 slides into buttoned-up status, the edge 21 of doorframe 2 is just in time corresponding with this limited block 3, and correspondingly, edge 21 is provided with the inner sunken face that can match with corresponding limited block 3 symmetrically at external surface and inner surface, and inner sunken face is along vertical setting of edge 21 and form a groove that vertically runs through 211.Also can on the inside wall of track 11, be embedded two elasticity limited blocks of relatively establishing 3 ', spacing so more reliable referring to Fig. 5, can prevent from better to move when door is closed and open automatically.

When doorframe 2 when track 11 slides onto closed condition, at this moment, the groove 211 that is opened on the doorframe edge 21 is relative with the limited block that is embedded on track 11 sidewalls just, under thrust, limited block slips in the groove 211, because, the inwall of groove 211 forms the curved surface of indent, make the both sides of groove 211 just in time block the two ends of limited block 3, play the effect of limit doorframe 21, to move door when closing, can prevent that edge 21 is subjected to the momentum effect of cabinet body frame 1 sidewall and causes that moving door opens automatically.
