Abstract
The utility model relates to a sliding seal structure of an inhaul cable. The sliding seal structure comprises a joint rod (1) of the inhaul cable and a guide tube (2), wherein one end of the joint rod (1) of the inhaul cable is slidably connected in the guide tube (2), a sealing cap (3) is arranged between the joint rod (1) of the inhaul cable and the guide tube (2) and is provided with a center hole (4), the inner wall of one end of the center hole (4) in the sealing cap (3) is in seal connection with the peripheral surface of the guide tube (2), the inner wall of the other end of the center hole (4) is in slidable connection with joint rod (1) of the inhaul cable, and the inner wall of the center hole (4) and the peripheral surface of the joint rod (1) of the inhaul cable are sealed. Compared with the prior art, the joint between the joint rod of the inhaul cable and the guide tube is sealed through the sealing cap, the joint rod of the inhaul cable and the sealing cap are in rigidity seal, the sealing cap is made of elastic or plastic material so as to be higher in thermostbility temperature compared with the rubber, and the sliding seal structure is unlikely to be damaged due to high temperature aging, thus having long service life.
Description
Technical field
The utility model relates to a kind of drag-line slipper seal structure.
Background technique
At present, the drag-line slipper seal structure of prior art comprises cable connector bar 1 ', dust-proof cover retaining ring 2 ', dust-proof cover 3 ' and guide pipe 4 ' as shown in Figure 1, described cable connector bar 1 ' one end is slidably connected in guide pipe 4 ', described dust-proof cover retaining ring 2 ' is socketed on cable connector bar 1 ', and with cable connector bar 1 ' interference fit, described dust-proof cover 3 ' is the rubber pipe of ripple, one end of dust-proof cover 3 ' is connected with dust-proof cover retaining ring 2 ', and the other end of dust-proof cover 3 ' is connected with guide pipe 4 '; But because this part-structure is arranged in the vehicle motor cabin, ambient temperature during work is higher, and often be in the larger environment of temperature variation, and the material of dust-proof cover 3 ' is rubber, easily appearance is aging and damaged, thereby loses due dustproof effect, although the high temperature resistant and ageing-resistant performance of the rubber of process vulcanizing treatment is better, but cost is higher, and working life is relatively still shorter under conventional environment; Drag-line need to often move reciprocatingly simultaneously, and the dust-proof cover 3 ' of bellows structure is subject to the effect of the compression and expansion of bellows Air in the to-and-fro motion process of drag-line, form larger vapour lock, makes the resistance of drag-line larger.
The model utility content
The utility model provides a kind of working life longer for above problem, the low less drag-line slipper seal structure of drag-line resistance that reaches of cost.
The utility model overcomes the above problems technological scheme used: a kind of rope slipper seal structure with following structure is provided, it comprises cable connector bar and guide pipe, described cable connector bar one end is slidably connected in guide pipe, be provided with sealed cap between described cable connector bar and guide pipe, described sealed cap is provided with center hole, one end inwall and the guide pipe outer circumferential face of described sealed cap center hole are tightly connected, the other end inwall and the cable connector bar of center hole are slidably connected, and seal between center bore inner wall and cable connector bar outer circumferential face.
after adopting above structure, compared with prior art, the utility model is owing to being provided with sealed cap between cable connector bar and guide pipe, sealed cap is provided with center hole, one end inwall and the guide pipe outer circumferential face of sealed cap center hole are tightly connected, the other end inwall and the cable connector bar of center hole are slidably connected, and seal between center bore inner wall and cable connector bar outer circumferential face, the joint of cable connector bar and guide pipe seals by sealed cap, and be hard sealing between cable connector bar and sealed cap, and the material of sealed cap is the material of elastomer or Plastic, has higher high temperature resistant temperature with respect to rubber, the situation that is not prone to high temperature ageing and damages, working life is longer, and the preparation process of sealed cap is also simpler, preparation cost is also just relatively low, be subjected to simultaneously the impact of resistance of air less, therefore the vapour lock that is subject to during the drag-line to-and-fro motion is less, i.e. resistance during drag-line motion is less.Therefore it is longer to the utlity model has working life, the low and less characteristics of drag-line resistance of cost.
As improvement, the position that described center bore inner wall and cable connector bar are slidably connected is provided with seal ring, after seal ring arranges, make that dust is more difficult to be entered in guide pipe from cable connector bar and guide pipe joint, thereby guarantee that the to-and-fro motion of cable connector bar has higher sensitivity, and then make longer service life of the present utility model.
As further improvement, the position that described center bore inner wall and guide pipe outer circumferential face are tightly connected is provided with annular protrusion, described guide pipe outer circumferential face is provided with the annular groove that coordinates with annular protrusion, described annular protrusion is positioned at annular groove, fastness after the Placement of this structure makes sealed cap and guide pipe is connected is better, and only need to be pressed into by instrument during assembling and get final product, need not other operation processes, assemble simpler, therefore can improve efficiency of assembling of the present utility model, and then reduce cost of production of the present utility model.
