Abstract
A tailed high-friction door stopper with an X-rotation tool rest is provided with a vacuum tool locked to the X-rotation tool rest for safety and relates to the technical field of manufactured parts of food machinery and small accessories for metal door frames of electrical instrument boxes. The door stopper is structurally modified into the tailed high-friction door stopper allowing for locking the vacuum tool on the X-rotation tool rest. The tailed high-friction door stopper with the X-rotation tool rest has the advantages that locking friction is increased greatly; the door stopper can move to and fro for more than one million of times, and service life of the door stopper is prolonged greatly; and the tailed high-friction door stopper is convenient for digital, normalized and standard production and mounting. The tailed high-friction door stopper with the X-rotation tool rest has the advantages of small size, compact structure, convenience in production, easiness in mounting, convenience in use and the like and can also be used for locking metal frames of vehicles, ships, airplanes, safes, containers, electrical instrument boxes and the like.
Description
Technical field
Food machinery finished parts electrical instrumentation case metal door frame annex.
Technical background
General doorframe locks with collision bead, to increase frictional force, with cabinet door, show window with friction lock in off position, one draws gently when needs are opened, and collision bead is namely to inside contracting, and frictional force reduces until eliminate, and doorframe or window can be opened.The collision bead principle is used for the X swivelling tool-holder, and the cutter locking in the rotation is an important link.
Summary of the invention
The object of the invention is to provide a kind of collision bead of special construction, enlarges its scope of application, changes serviceability:
1, energetically, significantly increase collision bead and close the frictional force of closing.2, frequent, the collision bead pass is closed number of times and can be reached millions of or several ten million times.3, series specification can be arranged according to certain rules to starting energetically the power of magnetic tape trailer collision bead, makes specification form series, makes its further digitlization, standardization, normalization.
The present invention can be achieved through the following technical solutions: the rear portion of collision bead (or cylinder) is increased the afterbody connecting rod, and method can directly be welded, and also can use whole of turner.This moment, the ball shape of collision bead became the ball link type, length increases several times, is installed in after then ball connecting rod and spring being entangled and justifies in the brief pipe, and the rear portion of short tube seals with packing ring, the foot piece of ball passes from the centre bore of packing ring, the ring of burn-oning again after foot piece passes.
When external force compacting collision bead, the collision bead connecting rod is mobile backward, suppresses simultaneously spring, and behind the displacement certain distance, spring reaction power is with the collision bead pop into position, thereby the collision bead connecting rod has been finished once compacting and the process that rebounds.
Wherein, collision bead is connected with connecting rod, and the specification requirement connecting rod points to the collision bead centre of sphere, and secondly connecting rod will have some strength, can not be crooked.Can select by experiment spring steel intensity thickness length.Certainly, the spring material preferably also is stainless, in case the inefficacy of getting rusty.Requirement to packing ring is that inner circle is slightly larger than the connecting rod external diameter, guarantees that the connecting rod turnover is convenient.That inner circle and connecting rod external diameter size match and be convenient to welding to the specification requirement of gasket ring.That retainer ring pad and packing ring need certain thickness at last, indeformable or minimizing distortion when welding.
Specific implementation method
Get one on stainless steel Φ 10mm ball pearl, get endlessly just one of round bar of φ 5, length is 17, with its welding.The specification requirement round bar is aimed at the ball center.Get one of Φ 12 pipe (internal diameter is about 10.2), be cut into 17 length.Get Φ 10 thick washers, the endoporus car becomes Φ 12, makes retaining washer, it is enclosed within on the pipe of Φ 12 welds.Note neat mouthful of retaining washer welding and Φ 12 pipes.Get one of Φ 6 thick washer, get one of Φ 9 annulus, endoporus Φ 5.1, thickness are about 3 millimeters, during assembling the collision bead connecting rod are contained in Φ 12 pipes, and the spring of packing into puts Φ 6 thick washers.Putting Φ 9 annulus.To can use in round bar and the welding of connecting rod afterbody.
Above-mentioned magnetic tape trailer energetically collision bead can be used on the X-type swivelling tool-holder, is used for the locking of hollow cutter, prevents from that cutter from coming off to cause injury to personnel, has the lock jail, and good stability is made the characteristics such as easy, easy to use.
Description of drawings: accompanying drawing is the structural representation of magnetic tape trailer collision bead.The Lower Half of master map is section's view: 1, collision bead ball, 2, retaining washer, 3, cylinder, 4, spring, 5, connecting rod, 6, thick washer, 7, annulus.
Claims (1)
1. magnetic tape trailer collision bead energetically is contained in the cylinder spring of packing into after architectural feature is to bump ball and the connecting rod electric welding is connected.The cylinder front portion packing ring of burn-oning is used for energetically collision bead fixing of magnetic tape trailer.Cylindrical rear portion seals with packing ring, and connecting rod passes from rear portion packing ring mesopore, puts annulus, the welding jail.
