CN2806665Y - Connecting structure for support pole and joint - Google Patents

Abstract

The utility model discloses a connecting structure for a supporting rod and a joint, wherein the end of the supporting rod is provided with a concave pit. The joint is coated and shaped on the outside of the end of the supporting rod. Because the concave pit is arranged on the end of the supporting rod, injection molding materials can be buried and arranged in the concave pit to lead the matching of the joint and the supporting rod to play the role of positioning and fixed connection in the radical direction of the supporting rod after the joint is coated and shaped on the end of the supporting rod. When the utility model is actually used, the supporting rod can not easily rotate and get loose in the joint. The utility model ensures the firmness of the connection of the supporting rod and the joint, and extends the service life of the supporting rod of a tent.

Description

The syndeton of pole and joint

Technical field

The utility model relates to a kind of each pole in the tent pole and syndeton of joint of being applied to.

Background technology

As shown in Figure 1, the common support bar 1 of tent ' by several poles 11 ' be formed by connecting, for ease of collection, this several poles 11 ' be can fold mutually to fold, so each pole 11 ' the end all be installed with joint 12 ' and realize pivot joint mutually.

As shown in Figure 2, traditional tent pole 1 ' be its requirement in light weight, that support degree is strong of assurance, its each pole 11 ' mostly be the glass material to make, joint 12 ' then with plastic rubber shaping.And the connection of the two is to adopt plastic mode one-body molded, when promptly making, with pole 11 ' the end place mould, again joint 12 ' straight forming is coated on pole 11 ' the end.Yet, because the two difference on material, and pole 11 ' the surface be shiny surface, its with joint 12 ' between to combine dynamics not enough, in actual use, pole 11 ' can appear at the phenomenon of joint 12 ' middle rotation or even disengaging causes support bar 1 ' can't normally use.

The utility model content

The purpose of this utility model provides the syndeton of a kind of pole and joint, and it can make each pole of tent more firm with cooperating of joint, is difficult for breaking away from, and guarantees the application life of tent pole.

For realizing technical purpose, technical solution of the present utility model is: the syndeton of a kind of pole and joint, and wherein place, the end of pole is provided with pit, and joint is overmolded in outside the end of pole.

Described pit is provided with more than one and one.

After adopting such scheme, because the utility model is to be provided with pit in the end of pole, then joint is after being overmolded in the end of pole, injection molding material can be embedded in this pit, make joint and pole be engaged in pole an affixed effect in location radially arranged, therefore in actual use, pole being difficult for appears at and rotates the problem that gets loose in the joint, guarantee the fastness that pole is connected with joint, thereby prolonged the application life of tent pole.

The specific embodiment

As shown in Figure 3, the syndeton of pole of the present utility model and joint comprises pole 11 and joint 12.

Key of the present utility model is: the place, end of this pole 11 radially is provided with a pit 111; 12 of joints are overmolded in outside the end of pole 11 (as shown in Figure 4).

Please cooperate shown in Figure 4 again, the utility model is when making moulding, pole 11 ends that are provided with pit 111 are placed mould, with the plastic rubber ejaculate molding technology joint 12 is overmolded in the end of pole 11 again, and owing to injection molding material can be embedded in this pit 111, make joint 12 and pole 11 be engaged in pole 11 an affixed effect in location radially arranged, therefore pole 11 is difficult for appearing at the problem that rotation gets loose in the joint 12, guarantee the fastness that pole 11 is connected with joint 12, thereby prolonged the application life of tent pole 1.

As shown in Figure 5, pole 11 ends can be provided with more than one pit 111, then can form than the 111 more radial locations of a pit, make pole 11 more firm with being connected of joint 12.

Claims (2)

1, the syndeton of a kind of pole and joint is characterized in that: the place, end of pole is provided with pit, and joint is overmolded in outside the end of pole.

2, the syndeton of pole as claimed in claim 1 and joint is characterized in that: pit is provided with more than one and one.
