Description

Safe device for quickly disassembling

Technical field: the utility model belongs to bicycle or Kickboard Scooter accessory field, relates in particular to the safe device for quickly disassembling of a kind of bicycle or Kickboard Scooter vehicle frame or seat pipe.

In the prior art, flexible siphunculus in the past is the vertical tube that utilizes a caliber less mostly, plug and be assembled in the bigger vertical tube of a caliber, Tong Shi And is by the mode of a screw to screw tight or to unscrew, the location when elongating or shortening to control this two vertical tubes operation with unclasp; But because in that use should be flexible during siphunculus, operator's this two vertical tube that must rotary screw be locked just can make firmly unlikely rocking of two vertical tubes location; Otherwise desiring to unclasp when adjustment should be stretched siphunculus also needs make it to unclasp by this screw of turn, and then the adjustment of flexible this two vertical tube of operation; Therefore, be somebody's turn to do flexible siphunculus in the vehicle frame of bicycle or Kickboard Scooter, when seat is managed in use, the operator often seems that in the adjustment use numb Trouble consuming time and operation are inconvenient.

For separating this Ask Questions of Decision, at present on the vehicle frame of bicycle or Kickboard Scooter, seat pipe, all can make this vehicle frame, seat pipe or the vertical tube can the packing location usually with a device for quickly disassembling, and then reach can quick adjusting purpose; The design of this type of device for quickly disassembling is to carry out the operation that adjustment was located or unclasped in packing with an operation handle Come, therefore make this vehicle frame, seat pipe or vertical tube usually at bicycle or Kickboard Scooter when using operation, avale to touch in careless feelings because of operator or the third party easily and pull pressure, even touch because of accident and to have pulled this handle, this vehicle frame, seat pipe or the vertical tube that causes being forced to the tightening position produces the loosening and influence safety when using.

In view of this, the someone designs a kind of quick detach that prevents by the safeguard construction of pulling arbitrarily; See shown in Figure 1, Fig. 1 is the block diagram of No. 439886 novel patent in Taiwan " structural improvement of safe quick detach ", this device for quickly disassembling 90 is by the bolt 91 of a pre-sizing, and is linked to one of bolt 91 1 ends trigger piece 92, one cushion blocks 93 and a nut 94 and forms.The trigger piece 92 of this device 90 is provided with two through

holes

95 and 96 at a distance of preset distance, stretches through for one of the not isometric U type depression bar 97 of two ends, and the long end of this depression bar 97 is provided with a press head 98 and one of stretches through spring 99; Utilize the short end of this depression bar 97 to limit the trigger piece 92 of this locking back by this, so that be not subjected to be pullled out because of the collision or the staff shake-up of accident.

But this device for quickly disassembling 90 in use, because the press head 98 of this U type depression bar 97 and the design of U kenel sample outwards protrude out, therefore causes other foreign matter that hook can take place easily and draw feelings heavy; Moreover if this device is used on such vehicle such as bicycle or Kickboard Scooter, The causes the user easily to be pulled by foreign body hook when driving very easily and causes danger, and makes this device for quickly disassembling 90 defectiveness still in the use.

Someone works out a kind of device for quickly disassembling in addition, as shown in Figure 2, it is the generalized section of the novel patent of Taiwan the 437872nd No. " quick-disassembly structure of tool safety lock ", its main technical characterictic is that one of this quick-disassembly structure 80 swing handle 81 offers opening 89, and be equiped with an elastic element 82, a fixed pawl 83, a steel ball 84 and a seal ring 85 from inside to outside in regular turn in this opening 89, this fixed pawl 83 is that to constitute ladder by a bigger diameter end 86 and a miner diameter end 87 shaft-like; In use, because this fixed pawl 83 is subjected to the elastic force effect of this elastic element 82, can make this steel ball 84 of its bigger diameter end 86 Will towards a pivot hole 88 direction is set holds, and this steel ball 84 can be embedded in this pivot hole 88, impel this swing handle 81 to be subjected to these steel ball 84 clips and can not be pulled, and when pushing the miner diameter end 87 of this fixed pawl 83, utilize the drop of these fixed pawl 83 large and small footpath ends 86 and 87, the inlay card that this steel ball 84 is broken away from this pivot hole 88, this moment, this swing handle 81 can be pulled.

Yet, though can reaching, this quick detach 80 can not touch operation because of accident, the car pipe or the seat pipe that cause being forced to the tightening position produce loosening situation; But the composition member of this quick detach 80 is comparatively various, it is also comparatively complicated that so Qi Installed establishes program, often cause when the processing assembling in case work programme is various, the quality instability takes place easily, make the product fraction defective also improve relatively, package program Bu Sudden and member are various simultaneously, and its manufacturing cost also Will is higher relatively, therefore make this quick detach 80 still have and wait improvements.

The purpose of this utility model is to provide a kind of safe device for quickly disassembling, can guarantee the state of quick detach packing location, preventing the operator when using, pulls or unexpected the shake-up relax because of careless, and the while member is more simplified effectively, takes into account safety.

A kind of safe device for quickly disassembling of the utility model includes pulls handle, and it is provided with an eccentric pivot hole and a containing hole, and is provided with the through hole that one of can be interconnected in this axis hole and this containing hole Zhi Inter; One axostylus axostyle, it has the opposite end that a pivot end and an external thread part are located at this pivot end, and this pivot end can be hubbed at this by a bolt and pull on the handle, and is formed with a short slot in this pivot end periphery toward this containing hole direction; One clip assembly is mounted on this and pulls on the handle, includes a spring and is located in this containing hole, one brake is located in the interior And of this containing hole and is pressed against on this spring, and in ccontaining this through hole of a ball, it can be embedded at the short slot of this axostylus axostyle and the neck of this brake in good time; Yi Jin Clip spare is in being axially arranged with a perforation to be sheathed on this axostylus axostyle; One nut, spiral shell are located at threaded portion outside this axostylus axostyle.

The utility model has following advantage owing to adopt said structure:

1. the utility model safety device for quickly disassembling utilization member still less prevents to pull the operation mechanism that relaxes because of accident with regard to producing, simultaneously with effect easy and simple to handle, thereby the purpose of attainable cost utility model;

2. safe device for quickly disassembling of the present utility model is because member is less, but therefore the use of saving member and the manufacturing cost of package program, and can reach the effectiveness of expection.

The utility model is by this practicality, and the project organization of novelty provides a kind of device for quickly disassembling of more simplifying effectively and taking into account security function.
