Description
Technical field
The utility model relates to elevation and subsidence mechanical manufacturing technology field, especially electric pushrod damping and slide-prevention system.
Background technique
Current other electric pushrod of high-end technical grade configuration is integrated with the protective measures such as limit switch, clutch, brake system.Push rod, under normal steadily loading condition, can meet practical application.But in some Special use occasions, under such as in use having larger impact force action, often there will be brake system and cannot continue locking, cause complete machine to glide the phenomenon of even damaging.
Model utility content
The utility model, for the deficiencies in the prior art, proposes electric pushrod damping and slide-prevention system, the impact force produced can be laid down, avoid it to cause damage to electric pushrod under rugged environment.
In order to realize above-mentioned model utility object, the utility model provides following technological scheme:
Electric pushrod damping and slide-prevention system, comprises telescoping inner, fixed end, nut casing, adjustable bolt and damping spring,
Described adjustable bolt is placed in described telescoping inner, and is threaded with described fixed end bottom,
Described nut casing is enclosed within described telescoping inner and is enclosed within outside described fixed end, and is connected with described telescoping inner, and described connection end top engages with described nut casing inwall,
It is outside that described damping spring is enclosed within described fixed end, and top engages with described fixed end, and bottom engages with described nut casing.
Further, described nut casing comprises riffled tube and sleeve pipe, and described riffled tube is connected with described telescoping inner end thread, described casing pipe sleeve in described fixed end bottom,
Described riffled tube internal diameter is greater than described casing inner diameter, and described casing inner diameter is less than described telescoping inner internal diameter.
Further, described sleeve pipe and described riffled tube joint are provided with step, and described fixed end top is provided with step, described damping spring two ends respectively with engaging with the step on described nut casing on described fixed end.
Further, described adjustable bolt comprises connection end and screw, and described screw is threaded with described fixed end bottom through described connection end from bottom to top,
The cross-sectional diameter of described connection end is corresponding with described telescoping inner internal diameter.
The utility model electric pushrod damping and slide-prevention system; damping and slide-prevention is carried out by damping spring; the impact force produced under can effectively disperseing rugged environment; reduce the pressure of push rod brake system; prevent the abnormal slip of the inner driving mechanism of whole push rod, avoid because the abnormal slip of driving mechanism causes damage to push rod, damages.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of electric pushrod damping and slide-prevention system described in the utility model;
Fig. 2 is electric pushrod damping and slide-prevention system cross-sectional schematic described in the utility model;
