Abstract
The utility model discloses a compression spring fixing device of a releasing device, the compression spring fixing device comprises a leading screw transmission assembly, a toggle clamp, a positioning device and a locking device, the leading screw assembly consists of a handwheel, a leading screw, a sleeve and a pressing plate; the toggle clamp is connected to the positioning device via a bolt, the leading screw transmission assembly can be clamped by pushing the toggle clamp, otherwise, the leading screw transmission assembly can be loosen by retracting the toggle clamp; the pressing plate of the leading screw transmission assembly is contacted with a spring, a rotatory handwheel is clamped the spring to the final state; the locking device is provided with a screw which can be rotated to the locking identification part to lock the spring while the spring is clamped.
Description
Technical field
The utility model relates to a kind of spring compression mechanism, is specifically related to a kind of releasing device holddown spring fixing device.
Background technique
Chinese patent CN 101769279A discloses a kind of locking device on 07 07th, 2010, mainly solve the existing problem that locking device is not quick detachable, reliability is low.This locking device comprises screw rod, snap close and lock wheel, the lock wheel is made of swivel nut, lock wheel back-up ring, spring and lock tube, screw rod one end is provided with the fixedly connected fixed hole of equipment, the screw rod the other end is provided with lock wheel back-up ring and prevents that the lock wheel from coming off, be respectively equipped with sawtooth on snap close and the lock wheel, snap close sawtooth and lock wheel engagement, prevent that the locking back is because of the loosening disengagement of factors such as jerk, when needs are thrown off locking device maintenance replacing, only need to apply longitudinal force along the screw stem direction, make engagement partly throw off and get final product, simple to operate, need not by instrument.
Releasing device offers when product is done jar test and uses, need to be released device and put the release tube into, the centre is to be connected by a holddown spring, under the peacetime state, holddown spring is locked, and when the holddown spring release, holddown spring is because the elastic force of self, begin to return to open configuration by confined state, will be released device and eject.Releasing device is put into when discharging tube, spring is initially open configuration, will be released device and begin to contact with pressure spring, certainly will cause that to be released device stressed, and be released device owing to can not be stressed, so just need compress the spring into abundant impaction state earlier.
The model utility content
At the above-mentioned deficiency of prior art, technical problem to be solved in the utility model is to propose a kind of releasing device holddown spring fixing device, utilizes this device can compress the spring into impaction state earlier, releasing device is put into to discharge tube again.
The utility model is as follows for the technological scheme that solves its technical problem and adopt: a kind of releasing device holddown spring fixing device, it is characterized in that, comprise lead screw transmission combination, elbow folder, positioning device and locking device, the lead screw transmission combination is combined by handwheel, leading screw, sleeve and pressing plate; The elbow folder is connected on the positioning device by bolt, and the elbow folder is released can be with lead screw transmission combination chucking, and the withdrawal of elbow folder can be unclamped the lead screw transmission combination; Pressing plate in the lead screw transmission combination contacts with spring, rotation hand wheel with spring compression to end-state; Locking device has screw rod, when spring is compacted screw rod is rotated to locking sign place spring is locked.
Embodiment subsequently will prove, utilize the utility model device can compress the spring into impaction state earlier, releasing device be put into to discharge tube again, and then overcome the technical problem that exists in the prior art.
Description of drawings
Fig. 1 is the structural representation (pressed status) of the utility model releasing device holddown spring fixing device.
Fig. 2 is the structural representation (locking state) of the utility model releasing device holddown spring fixing device.
Wherein: 1 is the lead screw transmission combination; 2 are the elbow folder; 3 is positioning device; 4 is locking device; 5 is handwheel; 6 is leading screw; 7 is sleeve; 8 is pressing plate; 9 for discharging tube; 10 is screw rod.
Embodiment
Below in conjunction with the drawings and specific embodiments, further set forth the utility model.These embodiments be interpreted as only being used to the utility model is described and be not used in the restriction protection domain of the present utility model.After the content of having read the utility model record, those skilled in the art can make various changes or modifications the utility model, and these equivalences change and modification falls into the utility model claim institute restricted portion equally.
Shown in Fig. 1-2, a kind of releasing device holddown spring fixing device that the utility model preferred embodiment provides comprises lead screw transmission combination 1, elbow folder 2, positioning device 3, locking device 4, handwheel 5, leading screw 6, sleeve 7, push pedal 8, discharges tube 9 and screw rod 10.Lead screw transmission combination 1 is combined by handwheel 5, leading screw 6, sleeve 7 and pressing plate 8; Elbow folder 2 is connected on the positioning device 3 by bolt, with lead screw transmission combination chucking or unclamp; Pressing plate 8 in the lead screw transmission combination 1 contacts with spring, and rotation hand wheel 5 is with spring compression; Locking device 4 has screw rod, and screw rod opens spring is locked when spring is compacted.
Below in conjunction with description of drawings course of action of the present utility model.
At first positioning device 3 is passed through three groups of screw on the base plate of product, then lead screw transmission is made up 1 to backspin, when the pressing plate in the lead screw transmission combination 18 contacts with spring, need slowly rotation hand wheel 5, and then spring slowly compressed, until to desired location, the screw rod 10 on the locking device 4 (original state be in the cylndrical surface) rotates along having decided direction then, until screw rod 10 is opened, and then spring is locked.
Claims (1)
1. a releasing device holddown spring fixing device is characterized in that, comprises lead screw transmission combination, elbow folder, positioning device and locking device, and the lead screw transmission combination is combined by handwheel, leading screw, sleeve and pressing plate; The elbow folder is connected on the positioning device by bolt, and the elbow folder is released can be with lead screw transmission combination chucking, and the withdrawal of elbow folder can be unclamped the lead screw transmission combination; Pressing plate in the lead screw transmission combination contacts with spring, rotation hand wheel with spring compression to end-state; Locking device has screw rod, when spring is compacted screw rod is rotated to locking sign place spring is locked.
