Description

Telescopic rod

Technical Field

The utility model relates to a can be located the telescopic link that supports to separating the curtain on the wall of both sides, belong to articles for daily use technical field.

Background

In daily life, a partition curtain is generally used, such as a curtain for preventing sunshine, a bath curtain for isolating a bathroom from a toilet, a medical partition curtain for isolating a sickbed in a ward, and the like, and the partition curtain is generally hung through a support rod installed between two opposite walls in a room.

The utility model with the publication number of CN206151162U discloses a curtain spacer positioning telescopic rod, wherein two ends of a supporting outer pipe and a supporting inner pipe are respectively provided with a propping end and a lapping end, the lapping ends of the supporting outer pipe and the supporting inner pipe are oppositely arranged, the lapping end of the supporting inner pipe penetrates into the supporting outer pipe through the lapping end of the supporting outer pipe, and pipe end supporting caps are respectively arranged on the propping ends of the supporting outer pipe and the supporting inner pipe; a guide support column fixedly arranged at the overlapping end of the support inner pipe; the guide spiral positioning spring is arranged in the support outer pipe and the support inner pipe, and the pitch of a guide section of the guide spiral positioning spring is at least larger than the diameter of the guide support column; the inter-pipe transition sleeve is arranged at the lap joint end position of the supporting outer pipe; the extrusion buffering component is fixedly arranged on the pipe end supporting cap. When the supporting device is used, the abutting end of the supporting outer pipe is abutted against a wall on one side through the pipe end supporting cap and the extrusion buffering component, then the supporting inner pipe is rotated, the supporting inner pipe drives the guide supporting column to spirally screw out along the spiral direction of the guide spiral positioning spring, when the abutting end of the supporting inner pipe abuts against the wall on the other side through the pipe end supporting cap and the extrusion buffering component, the supporting inner pipe is continuously rotated, and the guide supporting column applies pressure to the guide spiral positioning spring to enable the abutting end of the supporting inner pipe to stably abut against the wall on the other side; when the inner pipe is disassembled, the inner pipe is supported in a reverse rotating way. No matter whether the guide support column can smoothly rotate relative to the positioning spring or not, the use is very inconvenient in terms of the fact that a plurality of turns are needed to adapt to the lengths between different walls.

In order to achieve the above object, the utility model discloses a telescopic link, including pipe one, pipe two, pipe one can insert pipe two is located spring, circular shape packing ring and card in the pipe two, the one end of spring with the one end rigid coupling of pipe one, the other end rigid coupling in proper order of spring packing ring, card, the external diameter of packing ring is less than the internal diameter of pipe two, the external diameter less than or equal to of spring pipe internal diameter, under free state the external diameter of card equals or slightly is greater than the internal diameter of pipe two.

Further, the card is cut apart into a plurality of lobes by a plurality of clearances, every the lobe is to keeping away from the one side of packing ring warps.

Furthermore, the gasket and the clamping piece are provided with center holes, one end of the spring fixedly connected with the gasket and the clamping piece is gradually narrowed into a cone shape, a frustum-shaped plug is plugged into the spring, a threaded hole is formed in the center of the plug, and a screw rod of a screw sequentially penetrates through the center holes of the clamping piece and the gasket to be in threaded connection with the threaded hole of the plug.

Further, the length of the first tube plus the spring is greater than that of the second tube.

The outer wall of the pipe hoop is spliced with the inner wall of the second pipe, and the inner wall of the pipe hoop is spliced with the outer wall of the first pipe.

Furthermore, the wall structure further comprises a third pipe, and the third pipe can be spliced with the first pipe or the second pipe to adapt to wider wall space.

Compared with the prior art, the utility model discloses simple structure only needs to pull out pipe two to a little more than can fix on the wall through compression spring after the length of wall interval with a tub, and it is very convenient to use.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Embodiment 1, as shown in fig. 1-7, the telescopic rod comprises a first tube 1, a second tube 2, a spring 4, a circular washer 5 and a clamping piece 6, wherein the first tube 1 can be inserted into the second tube 2, one end of the spring 4 is fixedly connected with one end of the first tube 1, and a plurality of concave pits can be punched inwards from the outer wall of the first tube 1 so that the part, extending into the first tube 1, of one end of the spring 4 is combined with the first tube 1. The external diameter of packing ring 5 is less than the internal diameter of pipe two 2, under free state the external diameter of card 6 equals or slightly is greater than the internal diameter of pipe two 2, the external diameter less than or equal to of spring 4 pipe 1 internal diameter, 6 petals 62 are cut apart into by 6 clearance 61 to the card 6, every petal 62 is to keeping away from one side of packing ring 5 warps. The packing ring 5 and the card 6 have centre holes, the rigid coupling of spring 4 the one end of packing ring 5 and card 6 narrows down gradually into the toper type, the embolism 9 of a frustum form is packed into in the spring 4, embolism 9 center sets up the screw hole, and the screw rod of screw 7 passes in proper order the centre hole of card 6 and packing ring 5 with the screw hole spiro union of embolism 9 makes the other end of spring 4 rigid coupling in proper order packing ring 5, card 6. The length of the tube one 1 plus the spring 4 is greater than the length of the tube two 2. The pipe clamp comprises a pipe clamp 8, wherein the outer wall of the pipe clamp 8 is connected with the inner wall of the pipe II 2 in an inserting mode, and the inner wall of the pipe I1 in an inserting mode.

Since the locking piece 6 has a petal shape with a center convex toward the spring side, as shown in fig. 3 and 6, when the pipe is pulled right upward, the card 6 is in the "feathered" state, the tube can be smoothly displaced to the upper right relative to the tube, but when the tube is pushed to the lower left, the card 6 is in the "crevasse" state, since the locking piece 6 has a petal shape with a center convex toward the spring side, as shown in fig. 3 and 6, when the pipe is pulled right upward, the card 6 is in a state of 'feather', the tube can smoothly move towards the right upper direction relative to the tube, however, when the pipe is pushed to the left and downward, the card 6 is in the state of 'hip hair', the card 6 is deformed, the circumferential outer diameter is enlarged, the expansion rod is tightly expanded and does not stand still with the inner wall of the pipe II, the pipe I can only move a small distance relative to the downward left direction of the pipe through the compression spring, and the expansion rod can be tightly clamped between the walls through the change of the small distance. If the first tube is pulled out too much, the spring is still larger than the distance between the walls after being fully compressed, and when the first tube cannot be retracted, the first tube, the spring, the gasket 5 and the clamping piece 6 are pulled out of the second tube together, and the second tube penetrates through the other end of the second tube to be adjusted again.

Embodiment 2, the telescopic rod shown in fig. 8, is otherwise the same as embodiment 1, except that it further comprises a third pipe 3, and the third pipe 3 can be inserted into the second pipe 2 to adapt to a wider wall space. The outer diameter of the part of the pipe II 2 inserted into the pipe II is smaller than or equal to the inner diameter of the pipe II 2, and the outer diameter of the other part of the pipe II is larger than or equal to the outer diameter of the pipe II 2.
