Description
Technical field
The utility model relates to damping buffer, relates in particular to a kind of slide rail pneumatic damping buffer.
Background technique
Damping buffer is widely used in the opening and closing part of furniture, door and window etc., the impact endurance test shock when speed that it can effectively reduce folding contacts with associated components; What generally adopt at present is hydraulic damping buffer and aerodynamic retarder; Representative hydraulic bjuffer as disclosed in patent No. ZL201210212146.3 and the disclosed pneumatic buffer of patent No. ZL200520059637.4.
Hydraulic damping buffer is owing to adopting hydraulic oil as working medium, and the mobility of hydraulic oil is comparatively responsive to temperature variation, and this has directly affected the stability of hydraulic damping buffer work; And hydraulic oil has the shortcomings such as corrosivity, the structure and material of the cylinder body in buffer and air locking is had relatively high expectations; If hydraulic oil is revealed in work, buffer effect meeting obviously declines, and even directly scraps.
By the contrast of above-mentioned patent structure, obviously aerodynamic retarder has comparatively significantly advantage than hydraulic damping buffer; Its working medium character is comparatively stable on the one hand, this makes aerodynamic retarder can adapt to comparatively harsh working environment, on the other hand, and because aerodynamic retarder seal request is low, can adopt common plastics cylinder, this has greatly simplified overall structure and the manufacture difficulty of buffer.
Current aerodynamic retarder adopts the shape and structure of pneumatic buffer as above mostly, this structure does not have symmetry properties, and cannot be according to the stroke that needs lock cylinder or gas bar of buffer switch displacement, this makes buffer still stressed when not working, thereby reduce the tired structural strength of bumper portion element, reduced the working life of aerodynamic retarder; And dissymmetrical structure makes aerodynamic retarder poor work stability, especially, when cylinder or the motion of gas bar, can cause aerodynamic retarder local pressure uneven, also aggravated component wear; In order to improve wear resistance, structural strength and the working life of existing buffer, its main parts size has to adopt ferrous products, and this certainly will increase difficulty and the cost of buffer manufacturing.

The utility model is achieved like this, a kind of slide rail pneumatic damping buffer, it comprises air cylinder support and is connected to the Pneumatic assembly in air cylinder support, it is characterized in that, on described air cylinder support, slidably connect two base plate slide blocks, and described base plate slide block lays respectively at the place, both sides that is positioned at Pneumatic assembly, and described base plate slide block is about air cylinder support axis symmetry arrangement along its length, and one end of described air cylinder support is provided with the extension spring for Pneumatic assembly stroke is replied.
Described damping buffer also comprises for limiting snap close and the lock-off hook of Pneumatic assembly stroke; Described snap close axle is connected on air cylinder support, and snap close and lock-off hook are fastened and connected; Between described Pneumatic assembly and lock-off hook, be provided with the piston head that can make snap close and lock-off hook depart from when Pneumatic assembly stroke motion, described piston head is ladder structure of right angle, and wherein the one end near snap close and lock-off hook is trapezoidal top.
Preferably: described extension spring is also about air cylinder support axis symmetry arrangement along its length, and lay respectively at the outside, same one end of base plate slide block.
Described Pneumatic assembly comprises gas bar, gas bar positioning block and piston, and piston is connected to the end of gas bar, and gas bar positioning block is sleeved on gas bar, and gas bar positioning block is near piston; Described piston is connected with piston head.
Preferably: the gentle bar of described air cylinder support is all made of plastics; Described plastics are that ABS plastic and nylon mixing compacting form.
The beneficial effects of the utility model are: the whole symplex structure that adopts of the utility model is arranged, stressed even when buffer is slided, and have the stroke lock function of Pneumatic assembly, have guaranteed the Stability and dependability of buffer component operation; In the situation that not affecting working life, buffer main parts size adopts plastic article, has also reduced difficulty and the cost of manufacturing.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, Figure 2 and Figure 3, the utility model is achieved like this, it comprises air cylinder support 1 and is connected to the Pneumatic assembly in air cylinder support 1, its structural feature is, described air cylinder support 1 is positioned at place, Pneumatic assembly both sides and is connected with respectively a base plate slide block 2, as shown in Figure 4, Figure 5 and Figure 6, described base plate slide block 2 is about air cylinder support 1 axis symmetry arrangement along its length, and one end of described air cylinder support 1 is provided with the extension spring 7 for Pneumatic assembly stroke is replied.Described extension spring 7 is also about air cylinder support 1 axis symmetry arrangement along its length, and lays respectively at the outside, same one end of base plate slide block 2.
Described damping buffer also comprises for limiting snap close 6 and the lock-off hook 5 of Pneumatic assembly stroke; As shown in Figure 7, described snap close 6 axles are connected on air cylinder support 1, and snap close 6 is fastened and connected with lock-off hook 5; Between described Pneumatic assembly and lock-off hook 5, be provided with the piston head 4 that can make snap close 6 and lock-off hook 5 depart from when Pneumatic assembly stroke motion, described piston head 4 is ladder structure of right angle, and wherein the one end near snap close 6 and lock-off hook 5 is trapezoidal top.
As shown in Figure 8 and Figure 9, described Pneumatic assembly comprises gas bar 31, gas bar positioning block 32 and piston 33, and piston 33 is connected to the end of gas bar 31, and gas bar positioning block 32 is sleeved on gas bar 31, and gas bar positioning block 32 is near piston 33; Described piston 33 is connected with piston head 4.The gentle bar 31 of described air cylinder support 1 is all made of plastics; Described plastics are that ABS plastic and nylon mixing compacting form.
Working principle of the present utility model is such, and because the working environment of damping buffer is different with buffer level, Pneumatic assembly adopts the working mediums such as air, oxygen or nitrogen as required; When damping buffer is worked, gas bar 31 stretches, and now piston 33 backs down snap close 6 and lock-off hook 5 by piston head 4, and along with air cylinder support 1 slides along two base plate slide blocks 2, the extension spring 7 that is positioned at air cylinder support 1 end will stress deformation; Now be positioned at the air damping media flow of gas bar 31 to active section, the gentle bar 31 of now extension spring 7 all can reduce the vibratory impulse of external force in opening process well, and gas bar positioning block 32 defines gas bar 31 travel displacement well; When closure, external force disappears, and now, under the effect of extension spring 7 restoring forces, gas bar 31 shrinks; Gas bar 31 drives piston 33 and piston head 4 inwardly to move, and is positioned at the air damping medium back flow buffering of gas bar 31, can effectively reduce the speed while replying with damping adjusting buffer; And then avoided the vibratory impulse of buffer; When piston head 4 is displaced to relevant position, snap close 6 and lock-off hook 5 are again locked, and gas bar 31 strokes finish, and now, no matter whether extension spring 7 has restoring force all can not impact Pneumatic assembly; So just avoided the shortcoming of the long-term stressed wearing and tearing of Pneumatic assembly of traditional, pneumatic damper.
In addition, through reality, use, while using the Entry plastics such as ABS plastic to form with nylon mixing superzapping when the utility model parts, mixed plastic fittings after tested high temperature can reach 90 ° of degree, and low temperature can reach subzero 40 ° of degree.Element size data are change not, and while wherein adopting plastic cylinder, plastics gas bar, rubber piston, purity oxygen working medium, damping is best.
