FIELD OF INDUSTRIAL APPLICATION The present invention relates to a mounting collar for a pipe, for example for a gas pipeline, which is used to insert a pipe of smaller diameter into another pipe without damaging its jacket. This is required, for example, when passing pipes through railway ballasts. Furthermore, this type of mounting collar is also used to electrically isolate one tube from another, as in the case of metal tubes, and to protect the inner tube when inserting the tube into another tube. It can be held concentrically within the outer tube, and even if there is a gas leak in the inner tube, gas can freely flow into the space between the two tubes.
Gas can be reliably supplied to predetermined points. PRIOR ART In the prior art, this type of mounting collar consisted of a plastic strip whose ends were connected to each other by metal bolts or other joining devices and secured to the inner tube. (Problems to be Solved by the Invention) However, in the case of conventional collars of this type, it was time-consuming and troublesome work to reliably connect the ends with an appropriate clamping force. Furthermore, it was necessary to prepare a number of types of collars corresponding to the number of types of tubes with different diameters. Therefore, an object of the present invention is to provide a tube mounting collar that allows the ends to be easily and quickly connected to each other and reliably with appropriate clamping force, and that eliminates the need to prepare a large number of different types of collars. It is in. (Means for solving the problem) In order to achieve this object, the present invention provides a collar attached to an inner tube for inserting and holding a tube into a tube having a larger diameter than the tube. The collar is constituted by a flexible band of suitable thickness and capable of being wrapped around the tube, with a plurality of flexible bands spaced from each other in the axial direction of the band and extending perpendicularly to the band axis across the width of the collar. centering ribs are provided on one side of the band, and one end of the band has a male end having two rows of teeth projecting laterally from both edges of the band parallel to the axis of the band. and at the opposite end of the band,
two rows of meshing teeth meshing with the rows of teeth on the male end, and several plates disposed above each row of meshing teeth and located at approximately the same height as these plates; A corresponding guide member disposed opposite the plate forms an opening guide for accommodating and guiding the male end, and the tooth outline of each row of teeth is slidable in the direction in which the band ends are inserted into each other. It has a sawtooth shape that cannot be slid in the direction of extraction, and the tooth rows on both side edges of each end are shifted from each other in the axial direction, and the centering ribs closest to each end are arranged in opposite directions. After the ends are brought into contact with each other, the collar is configured as a lateral protrusion that can apply a traction action to facilitate clamping of the collar, and grooves are provided in the vicinity of the tooth rows on both side edges of the male end of the collar. Make a hole,
It is characterized by a structure that can be achieved by sequentially connecting several individual collars to extend the length of the collar in order to attach it to a pipe of 76.2 to 762 mm (3 to 30 inches). . (Operation) According to the mounting collar of the present invention, the mounting collar is wrapped around the inner tube and the male end is inserted into the opening guide of the female end. After the opposing ends are brought into contact with each other, the centering ribs closest to each end are tightened by applying a traction action with a tool, etc., and the teeth on the side edges of the male end and the female shape When the teeth on the inner edge of the opening guide at the end slide while engaging with each other, and the pulling operation is stopped at the position where an appropriate clamping force is generated, the serrated teeth will ensure that the clamping force is appropriate and the teeth will not come off. to ensure reliable fixation. Due to the arrangement of the teeth on both side edges offset from each other in the axial direction and the slots provided near the tooth rows on both side edges of the male end, the sequential sliding of the teeth in the direction of inserting the ends into each other is possible. It's done smoothly. Furthermore, by sequentially connecting the bands to each other by inserting the male and female ends, a mounting collar of any length can be made to fit any diameter tube. (Example) Next, the present invention will be explained with reference to the drawings. A first embodiment is shown in FIGS. 1 to 4, in which the male end 1 of the collar is made up of two identical pieces, both pieces provided with teeth 4 on their outer edges. A slot 3 is placed near the teeth 4 and parallel to the tooth row to facilitate insertion of the male end 1 into the opposite end 2 of the collar. A guide plate 5 is provided at the opposite end 2, and a tooth row 11 is arranged below the guide plate 5. The bridge 9 is provided with a guide member 6 which cooperates with the guide plate 5 to maintain the male end 1 downwards when the male end 1 is inserted into the opposite end 2. The guide plate 5 and the guide member 6 constitute an opening guide for accommodating and guiding the male end. The opposite end 2 thus forms a female end. The tooth rows 11 and 4 that engage with each other have an acute profile, and the male end 1
and the teeth are oriented so that they cannot be pulled out once the female ends 2 are engaged with each other. Two protrusions 7 are arranged on the male end 1 so that the protrusions 7 can be easily removed;
Allows the collar to be more tightly clamped to the tube when removed. This allows any variation in the thickness of the tube jacket to be accommodated. As shown, the collar 20 is provided with three lateral centering ribs 12 positioned perpendicular to the band axis to permit centering of the inner tube relative to the outer tube. These ribs are spaced 120° from each other when the band is closed in a circular shape. However, the number of ribs changes when, for example, a large number of collars are connected in sequence. Furthermore, the collar 20 is provided with two corrugated portions 10 to facilitate wrapping the collar around the tube, and the collar 20 is further provided with a longitudinal protrusion 8 so that when the collar is placed on the tube and tightened, the collar follows the tube. Prevent it from moving. Clamping the collar to the tube is achieved by the protrusion 13,
9 makes it easier to clamp the protrusions 13 and 9 by applying force, for example, with a tool. A second preferred embodiment of the tube mounting collar according to the present invention is shown in FIGS. 5-9. In the colors of this second example, color 4
0 male end 21 is made into a single unit, with rows of sharply contoured teeth 23 on both edges, and teeth 23 on both sides.
3 so that the arrays are shifted from each other.
The male end 21 is further provided with a slot 24 for weight reduction, and the slot 24 makes the male end more flexible. Also provided in the male end portion 31 is a perforated rib 25. These holes facilitate centering and installation of the collar with clamps and rivets. Two elastic ridges 33 are provided in the center of the collar, and the inner sides of these ridges are partially recessed to improve the flexibility of the collar. Further, centering ribs 26, 26a are provided in the center of the collar, and two holes 31 are provided in the rib 26a, so that these holes 31 cooperate with the holes in the rib 25 to allow the parts to abut. do. The edges of the ears 29 and 26, 26a are beveled to form a lead-in 27, which allows the collar to be attached to the tube and to facilitate sliding through any obstructions, such as welded seams. The ears 29 and the ribs 26, 26a are all useful for centering, and the ears 29 are particularly useful in this regard. The opposite (female) end 22 is provided with two toothed aperture guides 28 of cross section with teeth located on the vertical sides of the aperture guides 28, which toothed guides accommodate the male end 21 and Prevent it from falling out. On the other hand 2
The outwardly projecting tongues 32 facilitate insertion of the male end 21 into the opposite end 22. These two end teeth engage each other to prevent separation. the toothed opening guide 28 in the side portion 35;
Further, the lower portion 34 is provided with a depression to reduce weight and increase elasticity. Triangular longitudinal protrusions 30 can be provided on the inner surface of the collar to increase grip on the tube or any other lining and to prevent movement of the collar. The tooth 23 belonging to the male end 21 of the collar is the tenth
This is particularly effective when the shape is as shown in FIG. This shape of the tooth 23 was realized after much research and experimentation. The teeth at the opposite end 22 will of course have a profile that is complementary to the teeth at the male end, but will be about half the height of the teeth 23. Pitzchi is 4
The optimum dimensions of the tooth 23 in mm are as follows, with the unit being mm, a
=b=4, C=4.8~6.2, d=2.5, e=45°, f
= 10°, g = 20°. In this embodiment, each tooth has tapered serrations and bases with sides parallel to each other, and a row of slots between the bases of adjacent teeth allows the male end teeth to be flexible. The sliding engagement with the teeth on the female end is smooth. As is clear from the value of e, the male end 21 is slightly inclined towards the outer end. This allows the male end 21 to be easily inserted into the opposite end 22. As in the first embodiment of FIGS. 1-4, the teeth on each side of each end are staggered and preferably 17 on one side and 18 on the other side. According to the invention, instead of using one collar for a pipe of a certain diameter, several collars of similar shape can also be connected together to obtain a mounting collar for a pipe of a large diameter, which is advantageous. In some cases. For example, when using only two types of collar elements, Type B with a length (extended) of 295 mm and Type A with a length of 180 mm, the length is 76.2 mm to 762 mm (3 to 30 inches).
Can accommodate tubes with nominal diameters in the range of . This usage is shown in the table below.
