Abstract

Disclosed is a casing pipe. A bump is arranged at the middle position of an inner hole of the casing pipe via stamping and divides the inner hole of the casing pipe into two casing pipe inner insertion holes which can be in insertion connection with two tent rods or mosquito net rods respectively. The casing pipe has fast assembly speed and increased production efficiency without damaging the tent rods or the mosquito net rods or using adhesive for fixation during unfolding and bending of a tent or a mosquito net, and the casing pipe resolves the technical problem that respectively, the tent rods or the mosquito net rods are easy to be damaged and broken and have slow assembly speed in the prior art.

Description

Sleeve pipe

Technical field

The utility model belongs to tent, mosquito net accessory technical field, is specifically related to a kind of sleeve pipe that connects tent bar or mosquito net pole.

Background technique

Tent and mosquito net are to be bent to form tension force and to support by being through more piece tent pole and mosquito curtain pole on its drawstring, and between the tent bar or the connection between the mosquito net pole realize by sleeve pipe.Present sleeve pipe is divided into metal sleeve and non-metallic casing.Though existing metal sleeve intensity is good, but at tent, when mosquito net launches bending, the mouth of pipe of tent bar or mosquito net pole and sleeve pipe forms a strong point, but the mouth of pipe is more sharp-pointed, so be easy to tent bar, mosquito net pole in the making of mouth of pipe place damage glass fibre, tent bar or mosquito net pole are broken, influence its working life, when assembling the tent bar or an end of mosquito net pole and sleeve pipe to cling fixingly with glue, influence assembling speed; And non-metallic casing adopts plastics to make mostly, metal sleeve is low relatively on intensity, tent bar or mosquito net pole bending are easy to make this non-metallic casing fracture damaged when tent or mosquito net expansion, cause tent or mosquito net to use, make troubles and sustain a loss to the client, cause bad influence.

Summary of the invention

Goal of the invention of the present utility model is will provide a kind of and launch not damage tent bar or mosquito net pole when crooked at tent or mosquito net, not need to fix and sleeve pipe that assembling speed is enhanced productivity soon with glue, solved tent bar that prior art exists separately or the easy Damage and Fracture of mosquito net pole, the slow technical problem of assembling speed.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of sleeve pipe, neutral position, hole punching press within it has a salient point, to overlap pipe orifice is divided into two, form two sleeve pipe internal plug seats, two sleeve pipe internal plug seats can patch with two joint tent bars or mosquito net pole respectively, and its main points exist:

The diameter of described sleeve pipe internal plug seat is bigger slightly than the tent bar or the mosquito net pole diameter that insert in it, makes tent bar or mosquito net pole and its Spielpassung;

Punching press has the bar shaped boss of microscler projection in the sleeve pipe internal plug seat of described sleeve pipe one end, and the sleeve pipe internal plug seat of this end is fixedlyed connected with inserting its interior tent bar or mosquito net pole interference fit;

The diameter of the sleeve pipe internal plug seat of the described sleeve pipe the other end is because of than tent bar or the mosquito net pole slightly larger in diameter inserted in it, and with tent bar or mosquito net pole Spielpassung, tent bar or mosquito net pole can easily be inserted at the sleeve pipe internal plug seat of this end and transfer to, be convenient to the expansion and the folding of tent bar or mosquito net pole;

The mouth of pipe at described sleeve pipe two ends all has smooth chamfering, one of its advantage when assembling the tent bar or mosquito net pole do not damage tent bar or mosquito net pole when inserting in the sleeve pipe internal plug seat; Its advantage two when the tent bar that is connected with sleeve pipe or mosquito net pole are crooked, the mouth of pipe at tent bar or mosquito net pole and sleeve pipe two ends all forms the strong point, because of the mouth of pipe all has smooth chamfering, so can not damage tent bar or mosquito net pole;

Described sleeve pipe is a metallic material.

Adopted the utility model sleeve pipe of above technological scheme to have following advantage: 1. sleeve pipe one end and tent bar or mosquito net pole interference fit are fixed, saved that existing sleeve pipe and tent bar or mosquito net pole are fixing wants this link of viscose glue water, promptly saved the glue expense and make assembling speed increase substantially manufacturing efficiency soon again; 2. because of the mouth of pipe all has smooth chamfering, can not damage tent bar or mosquito net pole with assembling at tent bar or mosquito net pole bending.The utility model can be widely used on tent or the mosquito net.

Embodiment

By Fig. 1-7 expression be the utility model one embodiment, a kind of sleeve pipe, neutral position, hole punching press within it has a salient point 1, to overlap pipe orifice is divided into two, forming 2, two sleeve pipe internal plug seats 2 of two sleeve pipe internal plug seats can patch with two joint tent bars 5 respectively, and its main points exist:

The diameter of described sleeve pipe internal plug seat 2 is bigger slightly than tent bar 5 diameters that insert in it, makes tent bar 5 and its Spielpassung.

Punching press has the bar shaped boss 3 of microscler projection in the sleeve pipe internal plug seat 2 of described sleeve pipe one end, and the sleeve pipe internal plug seat 2 of this end is fixedlyed connected with inserting its interior tent bar 5 interference fit.

The diameter of the sleeve pipe internal plug seat 2 of the described sleeve pipe the other end is because of than tent bar 5 slightly larger in diameter of inserting in it, and with tent bar 5 Spielpassung, tent bar 5 can easily be inserted at the sleeve pipe internal plug seat 2 of this end and transfer to, be convenient to the expansion and the folding of tent bar 5.

The mouth of pipe at described sleeve pipe two ends all has smooth chamfering 4, and one of its advantage is not damaged tent bar 5 when tent bar 5 inserts in the sleeve pipe internal plug seat 2 when assembling; Its advantage two when the tent bar 5 that is connected with sleeve pipe is crooked, tent bar 5 all forms the strong point with the mouth of pipe at sleeve pipe two ends, because of the mouth of pipe all has smooth chamfering 4, so can not damage the tent bar.

Described sleeve pipe is a metallic material.

As Fig. 1 and shown in Figure 7, the one joint tent bar 5 that will be installed with bungee 6 during assembling inserts in the sleeve pipe internal plug seat 2 of an end of sleeve pipes, and punching press has the bar shaped boss 3 of microscler projection to make the sleeve pipe internal plug seat 2 of this end fixedly connected with inserting its interior tent bar 5 interference fit in the sleeve pipe internal plug seat 2 of this end; The other end of sleeve pipe is because of sleeve pipe internal plug seat 2 and tent bar 5 Spielpassung, and easily another joint of plug-in mounting is installed with the tent bar 5 of bungee 6; Operation can be together in series more piece tent bar 5 successively, two more piece tent bars 5 that connect is penetrated in the tent drawstring crooked fixing back again and forms tension force and support whole tent.

As shown in Figure 6, after tent is packed up, only need joint tent bar 5 of that end of pine and sleeve pipe are broken away from folding, operation can be folded up more piece tent bar 5 and be convenient to the packing collection successively.

The utility model is not subjected to the restriction of the above embodiments, and specific embodiment described herein only is that the utility model spirit is illustrated.Do not breaking away from spirit of the present utility model or surmounting under the defined scope prerequisite of appended claims; the utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, these modifications or replenish or adopt similar mode to substitute and all fall in claimed the utility model scope.
