Abstract
The utility model relates to a sealing connecting device for pneumatic pressurizing cradle bearing rod, belonging to a textile machinery, comprising a plurality of clamping screws (1), a sealing ring (5) and a clamping block (2) (4). The utility model is characterized in that: the head of the clamping screw is in a shape of polygon; a concave hole is arranged inside the head, and communicated with the inner through hole at the screw thread part sleeved with the sealing ring (5) and the clamping block (2) (4); and a soft rubber expanding block (3) is arranged between two clamping blocks. The working principle of the connecting device is that: the soft rubber expanding block (3) is clamped and deformed by two claming blocks (2) and (4) and the clamping screw, the periphery of the soft rubber expanding block is expanded outward, and contacted closely with the inner walls of the bearing rod, achieving the aim of sealing, and the connection with another bearing rod can be realized by arranging a connecting hose in the concave hole at the head of the clamping screw. The utility model overcomes the drawback of traditional adhesive sealing and has the advantages of easy processing, convenient installation, low cost, long service life, and reliable and stable sealing performance.
Description
The utility model relates to a kind of textile machine, a kind of specifically sealing and connecting device of pneumatic pressurizing cradle pole.
For this sealing and connecting device, existing technology is as the disclosed patent of CN1240842A, compressed air mechanism adopts the square hollow tube of anti-damage, and this compressed air mechanism is the part of the drafter of textile machine, promptly is called the pole of reel cage usually.The pole of the disclosure patent adopts seal member and connecting tube fixedly to form by adhesive with the sealing of pole with being connected, this jockey exists following insecure factor: the sealing that 1. shows pole is to stick with glue agent to seal, because of adhesive is a chemical reagent, under adverse circumstances, decompose easily, go bad, lose viscosity, it is loosening and leak gas to come seals high pressure gas that sealing very easily takes place with this; 2. adopt adhesive seal, to the required precision height of hole dimension, seal appearance and size in the pole, uniformity will be got well, and has increased difficulty of processing.Otherwise each limit, assembling back or each gap are inconsistent, get loose easily after the bonding and leak gas; 3. adopt adhesive to be bonded and sealed, need the regular hour because of adhesive solidifies, this has reduced production efficiency to a certain extent; 4. be bonded and sealed with adhesive, need special high-pressure injection equipment, this has increased production cost virtually; 5. adopt sealing ring to seal, for square endoporus, its reliability can be poorer.
The purpose of this utility model is: the sealing and connecting device to above-mentioned pole improves, and a kind of good seal performance is provided, the sealing and connecting device of reliable operation, handling ease, Pneuamtic cradle pole that cost is low.
The purpose of this utility model is to realize like this.In the adjacent facial canal of two reel cage poles that needs connect, respectively be provided with and comprise stretching screw (1), fixture block (2), (4), the jockey of soft rubber expanding block (3), sealing ring (5), an available cross over pipe connects between two jockeys.The shape of described fixture block (2) and (4) and soft rubber expanding block (3) is consistent with hole shape in the pole, and its outside dimension is slightly less than hole dimension in the pole, and keeps certain interval with the pole inner hole wall, so that install and maintenance; The head of stretching screw (1) adopts polygonized structure, be generally quadrangle or hexagon, head is provided with the spill circular hole, so that install and the pipe fitting that is tightly connected, screw inside is provided with through hole and connects with shrinkage pool in the head, so that gas enters pole, fixture block (2) is provided with through hole, and fixture block (4) is provided with screwed hole and and screw engagement.
Advantage of the present utility model: 1. this apparatus structure is simple, and the required precision of size is low, and handling ease to the basic zero allowance requirement of hole dimension in the pole, is installed and changed, and only needs a box spanner, and manual installation can be finished, thereby has reduced production cost; 2. be to utilize stretching screw (1) and fixture block (2), (4) that soft rubber expanding block (3) is compressed because of this device, make its distortion that expands also closely touch the pole inner hole wall, play the effect of sealing, to stick with glue the life-span that agent seals conspicuous much longer than existing for it.
Introduce an embodiment below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model user mode.
Fig. 2 is a structural representation of the present utility model.
At head of screw is on the screw rod of tightening screw (1) of shrinkage pool, is provided with sealing ring (5), fixture block (2) and fixture block (4), is provided with soft rubber expanding block (3) in the centre of two fixture blocks.Each part is installed and rotates to consistent direction, tighten gently and can put into reel cage pole endoporus smoothly after stretching screw (1) guarantees to tighten, after putting into certain position, stretching screw (1) is further tightened, made further distortion of soft rubber expanding block (3) with box spanner, the peripheral expansion of soft rubber expanding block (3), closely contact with the pole inner hole wall, realize effectively sealing, in the shrinkage pool of head of screw, insert tube connector, just can realize being tightly connected reliably between two reel cage poles.
Claims (2)
1, a kind of sealing and connecting device of pneumatic pressurizing cradle pole, comprise stretching screw (1), sealing ring (5), fixture block (2), fixture block (4), it is characterized in that: the head of stretching screw (1) is a polygon, be provided with shrinkage pool in the head, and connect with the through hole of threaded portion inside, the outside of screw (1) is by screw thread and fixture block (4) engagement, the threaded portion of stretching screw (1) is socketed with sealing ring (5), fixture block (2) and (4), is provided with soft rubber expanding block (3) between fixture block (2) and (4).
2, the sealing and connecting device of reel cage pole according to claim 1, it is characterized in that: described fixture block (2) is consistent with the shape of pole endoporus with the shape of fixture block (4) and soft rubber expanding block (3), its outside dimension is slightly less than hole dimension in the pole, fixture block (2) is provided with through hole, and fixture block (4) is provided with screwed hole.
