Specific embodiment

As shown in Figure 3, Figure 4, the damper of sliding rail, the technology hand implemented are used for described in the utility model embodiment one Section purpose to be achieved is not only to make guide rail laborsaving soft during pull-out, will also be with the variable quantity by pulling force of tension spring Certain association is formed, so that the variation of half tension spring tension can be reduced at least in the stroke that synchronous pull-out movement generates Amount, the technological means implemented includes dampener body 3.

It is further analyzed for the above dampener body 3 to be implemented:

The dampener body 3 implemented includes damping frame 32, damper tube 33, damping pipe support 34, and damping frame 32 therein is used Each corresponding damper assembly is fixedly mounted in the same space in cooperating with fixed frame 31, the fixed peace of damper tube 33 therein On damping pipe support 34 and the model of damper tube 33 can be replaced with size according to different product use demand；Meanwhile The gear transmission unit for being intended to implement for cooperation dampener body 3 is set in installation space, outside the damping pipe support 34 implemented Edge has one section of tooth socket II 310, and 32 edge of damping frame implemented has the one section tooth opposite with II 310 position of tooth socket Slot I 38, so that two sections of tooth sockets be made to constitute the gear cavity for installing gear transmission unit；

Further, for the gear transmission unit of above-mentioned implementation, the gear 37 including being fixed on respective teeth wheel carrier 36 should There are tooth rest 36 former and later two to be used to install the pin hole of pin shaft, that is, is respectively used to be fixedly connected with tension spring 35, gear is fixedly mounted 37, the gear teeth for the gear transmission unit excircle implemented are meshed with tooth socket I 38, the respective tooth of tooth socket II 310 respectively, thus During dampener body 3 generates displacement, tension spring 35 is driven to generate deformation while being driven gear transmission unit.

Further, for the damping pipe support 34 of above-mentioned implementation, which has active pin shaft and leads to 311 connection sliding block 4 of active pin shaft is crossed, 311 end of active pin shaft implemented is fixed on arc set by damping frame 32 and leads To the inside of slot 39, so that the motion track of active pin shaft 311 be made to be limited in implemented arc guide groove 39；

Correspondingly, the arc guide groove 39 of above-mentioned implementation, which is made of horizontal segment and bending section, above The activity trajectory for the active pin shaft 311 implemented is in the horizontal segment of arc guide groove 39.

Further implement for 4 specific structure of sliding block of above-mentioned setting:

Since connection sliding block 4 is implemented in damping 34 end of pipe support, the tool of sliding block 4 implemented is there are three interconnecting piece, and first, wherein One interconnecting piece is set as the movable pin hole 42 of the active pin shaft 311 to connect with damping pipe support 34；Second, one of interconnecting piece It is provided for that sliding block 4 is made to be fixed on the fixed column 43 being tilted a certain angle on arc guide groove 39 and upwards；Third, wherein one A interconnecting piece is provided for blocking the buckle slot 41 of 5 bayonet lock of sliding block button.

Further implement for 5 specific structure of sliding block button of above-mentioned setting:

Since sliding block 4 mutually forms clamping relationship with sliding block button 5 in the process of moving, the sliding button 5 implemented also has Have for the bayonet lock with the fixed clamping of buckle slot 41.

As shown in Fig. 5-1, Fig. 5-2, Fig. 5-3, Fig. 5-4, Fig. 5-5, sliding rail is used for described in the utility model embodiment one Damper, in use, when starting guide rail sliding, the sliding block 4 implemented is in the shape being tilted a certain angle upwards State, when not being in contact with sliding block button 5, fixed column 43 is stuck in the bending section of guide groove 39, i.e., as shown in fig. 5-1；Work as cunning Block 4 dextrad is mobile and when forming opposite and row with sliding block button 5, and the bayonet lock of sliding block button 5 comes into contact with and is caught in the buckle slot of sliding block 4 In 41, while 4 acclivitous one end of script of sliding block being forced to switch to rotate down certain angle, i.e., is to turn with active pin shaft 311 Moving axis rotates clockwise 17 °, while the fixed column 43 for being in script in 39 bending section of guide groove is moved to the water of guide groove 39 At the position that flat section connects with bending section, i.e., as shown in Fig. 5-2；When applied guide rail continues sliding, sliding block button 5 is in tension spring 35 with slowly resetted under the action of damper tube 33, i.e., as shown in Fig. 5-3；When act on sliding block button 5 pulling force be greater than tension spring 35 with And damper tube 33 pulling force when, sliding block button 5 starts to move right, i.e., as shown in Fig. 5-4；When sliding block button 5 continue to move right to When being detached from the buckle slot 41 of sliding block 4, sliding block 4 rotates 17 ° counterclockwise under the action of guide groove 39 and restores to making fixed column 43 are stuck in the state in 39 bending section of guide groove.

As shown in fig. 6, being used for the damper of sliding rail described in the utility model embodiment one, it is real which is based on institute The more long then relative tension of length for the tension spring drawing applied is bigger, due to closing between damping pipe support 34 and tension spring 35 for gear auxiliary driving System, transmission ratio 1:2, thus, for example, when tension spring 35 is implemented to elongate 25 unit lengths or total distance to be 1A, together Step can make sliding block button 5 that can move right 50 unit lengths or total distance 2A, imitate to reach sliding block button 5 and pull out labour-saving Fruit.
