Description

Rotation gate inhibition without main shaft welding

Technical field

A kind of rotation gate inhibition of no main shaft welding, belongs to public safety protective equipment.

Background technology

Existing cell gate inhibition product at least also has 20 years history, the passage of the product and forbidden shaftless rotation in China Pivoted arm, which always is, uses round stainless steel tube making, though it is good-looking extremely impracticable.When personnel's disengaging is frequent, every other day will Damage, i.e., the personnel for being just into and out cell are not frequent, damage in 1 year a ten come eight times it is also very common, not only spent, but also bothersome. Normally the material of stainless steel should be unusually strong, but how can also often damage！Examine it finds that：Fracture damage Bad occurred in the junction of gate inhibition's host rotary shaft and the rotating arm being connected thereto, and fracture is also not prison welding With weld seam it is too thin caused by, but main rotating shaft is inherently very heavy, in addition the upper arm for being welded in rotating arm thereon is not only long but also again, Rotary speed when work again too fast rotating arm one second closing or angle inswept in the opening time is excessive causes 's；And rotating arm is too short that the gap between the two-arm of left and right can be made excessive, pedestrian does not need to swipe the card can be from the seam between two-arm It is squeezed through in gap, has both influenced the function of gate inhibition, it is easier to damage rotating arm even gate inhibition's host.In addition to this, since gate inhibition is revolved The height of pivoted arm is too low, and many people is caused not have to swipe the card, can also be from the upper surface of rotating arm across both having encouraged uncivil situation Generation, also when crossing over arm to the pressure of rotating arm due to be easy to make rotating arm even gate inhibition's damage.

Invention content

The present invention damages frequent situation aiming at above-mentioned gate inhibition's rotating arm, manufactures and designs a kind of both light material-saving, section Be resistant to use, and avoid welding, easy maintenance and replacement the shaftless rotating arm of gate inhibition.The method applied in the present invention is, in intensity Under the premise of identical, first, the current vertical main rotating shaft of gate inhibition is cancelled, allow shaftless rotating arm i.e. gate inhibition's door directly and host Dynamical system be connected, not only saved material again mitigation host living load, also thoroughly eliminated main rotating shaft because with rotating arm （Door）Electric welding connection and caused by the trouble that is often broken, an arrow carves more and achieves many things at one stroke；Second is that shaftless rotating arm is made two Segmentation, leading portion with back segment by being stacked, the modes such as bushing plus screw, pin be connected, and two sections can be respectively using different Material type, material had not only saved material and have mitigated weight, but also facilitated installation, maintenance and replacement；Third, the main frame of shaftless rotating arm in addition to It is rectangular outer, it also can be made into the lighter triangle of weight and half elliptic etc.；Fourth, by shaftless rotating arm master Frame is changed to semicircle stainless steel tube or band iron shape, triangle, channel steel shape stainless steel by current tubular stainless steel tube, with The weight of shaftless rotating arm is greatly reduced；Fifth, in order to further mitigate the weight of shaftless rotating arm, when reducing rotation Inertia force, be connected directly one section of shaftless rotating arm and host makes of round or semicircle stainless steel pipe, and another section with flat Iron shape, channel steel shape or triangle stainless steel material make；Sixth, by the material of rotating arm into line replacement, i.e., by stainless steel material Changing aluminium into, albronze or other porous light metal materials can also use the non-metallic materials such as plastics even lightweight timber Material displacement, can so mitigate the weight of shaftless rotating arm, especially mitigate shaftless rotating arm significantly far from host side significantly Weight, to mitigate the torsion between host and shaftless rotating arm；Seventh, can also take in the increase of the upper end of shaftless rotating arm The mode that bend pipe is talked in a roundabout way more extends up the upper end of shaftless rotating arm main frame, to increase the shaftless rotating arm i.e. height of gate inhibition Degree, refusal someone cross over, and the function of gate inhibition and dignity is made to emerge from.Eigth, the reload buffer ball on shaftless rotating arm, To prevent shaftless rotating arm when opening and closing and the strong collision of mainframe box, finally to make gate inhibition's door become few repair The long-lived product not repaired even.To sum up, the rotation gate inhibition of no main shaft welding of the present invention, by shaftless rotation Arm, rotating arm connection nozzle, yielding rubber ball, arm heart standing screw, strength connecting rod, three connect the groups such as screw and shop bolt At, be markedly different from it is existing there is main shaft rotating arm to be characterized in that when the shaftless rotating arm directly with host power System is connected, second is that the shaftless rotating arm is two-part, third, the main frame of the rotating arm especially back segment（ Claim forearm end）Main frame also can also be triangle, trapezoidal, half elliptic, fourth, the nothing other than sleeping " M " shape Equipped with the yielding rubber ball for preventing rotating arm strong collision on axis rotating arm.

Description of the drawings：Fig. 1 is the structural diagram of the present invention, while being also Figure of abstract, and 1 is gate inhibition's host babinet, and 2 are Shaftless rotating arm, 3 connect nozzle for rotating arm, and 4 be the forearm arm heart, and the abbreviation arm heart, 5 be forearm, and 6 be yielding rubber ball, and 7 It is strength connecting rod for arm heart standing screw, 8,9 connect screw for three, and 10 be shop bolt, and 11 be original host live spindle.

Specific implementation mode：There are six steps for the specific implementation mode of the present invention, i.e.,：

First, with round stainless steel tube or semicircle stainless steel tube, according to attached appearance illustrated in Figure 1,4 are made closely The shaftless rotating arm 2 of " 7 " font, and necessary processing is carried out according to the requirement being connect with host side in one end, in the other end Necessary processing is carried out according to the requirement being connect with forearm 5 at rotating arm connection nozzle 3, total length is about the 1/ of total arm length 4 to 1/3, it is spare.

Second is that selection outer diameter can pack into the round stainless steel tube of the internal diameter of shaftless rotating arm 2 or semicircle stainless steel Pipe makes the forearm 5 of 2 nearly " M " shapes according to attached appearance illustrated in Figure 1, and on it lower two ports according to shaftless rotation The requirement that pivoted arm 2 connects carries out necessary processing（Punching）；According to the requirement being connect with strength connecting rod 8 at the forearm arm heart 4 Carry out necessary processing（Punching）, the length of the forearm 5 is about the 2/3 to 3/4 of total arm length, spare.

Third, making 2 strength connecting rods 8.

Fourth, above-mentioned parts are connected into two by the company's screw 9 of arm heart standing screw 7, three and shop bolt 10（Fan） Complete shaftless rotating arm（Door）, and yielding rubber ball 6 is installed on it.

Fifth, original host live spindle 11 is unloaded, by rotation gate inhibition's arm without main shaft welding of new production（Door）With host Drive system connects.

It is necessary that strength connecting rod [8] is installed on shaftless rotating arm, and effect is in addition to ensureing shaftless rotating arm 2 with before Being reliably connected for arm 5 is outer, and an important role is ensuring that two port rulers that shaftless rotating arm 2 is connect with host system It is very little to change, to ensure that the power of host is reliably delivered to shaftless rotating arm 2 always.

The purpose of reload buffer ball 6 on shaftless rotating arm is that shaftless rotating arm is opening and closing in order to prevent When with gate inhibition's host 1 --- the especially strong collision of mainframe box box section corner and the noise that generates therefrom.Anti-collision It is two hemisphere for having bolt-type to combine hook to hit yielding rubber ball 6, one presses to be combined into one and is fixed on nothing with strength after positioning On axis rotating arm, quantity can be one, can also be two or more.

It is also very light also to can be made into weight other than sleeping " M ", rectangle, triangle for the main frame at forearm end 5 It is trapezoidal, half elliptic etc..

Which kind of, to reduce inertia force when rotating, may be used also to further mitigate its weight at the either forearm end 5 of shape By material type selection band iron shape, channel steel shape and the triangle stainless steel material etc. of its main frame.Strength connecting rod 8 can also be simultaneously The design pattern not bery erected, quantity is also without limitations.

In order to further mitigate the weight of shaftless rotating arm 2, to reduce inertia force when rotating, shaftless rotating arm 2 and master Be connected directly one section of machine makes of round or semicircle stainless steel pipe, another section with band iron shape, channel steel shape or triangle not The Steel material that becomes rusty makes.It can certainly two sections of all use identical proximate matters making.

In order to increase the height and minuent of gate inhibition, can be installed additional in the upper and lower ends of the main frame of shaftless rotating arm 2 The ornament for welcoming or indicating warning not only increases and reduces and block height and minuent, but also shaftless rotation is not significantly increased The weight of arm also emerges from the function of gate inhibition and dignity.

Other than installing ornament additional, it can also take and increase the mode talked in a roundabout way bend pipe more in the upper end of shaftless rotating arm 2 The upper end of shaftless rotating arm main frame is extended up, to increase the shaftless rotating arm i.e. height of gate inhibition, refusal someone crosses over；When When the upper end main frame of shaftless rotating arm is band iron shape material, being extended up by the way of winding directly up can.
