Double-pipe elbow joint

Abstract

The utility model discloses a double-pipe elbow joint. The double-pipe elbow joint comprises a joint body, a connecting part is arranged on the bottom surface of the joint body; a mounting groove is further formed in the side face of the connecting part, and a connecting hole is formed in the end face of the connecting part. Due to the arrangement of the connecting part, the connector body can make contact with the supporting face through the end face of the connecting part, face-to-face contact between the connector body and the supporting face is achieved, and compared with line-to-face contact between the connector body and the supporting face in the prior art, the contact face of the equipment is larger; therefore, the connector body is more stable in use.

Description

Technical Field

[0001] The utility model relates to the technical field of pipeline joints, in particular to a double-tube elbow joint. Background Art

[0002] The existing pipe joints are connected to the supporting surface by passing bolts through the fixing holes provided on the side of the joint body, such as the prior art with patent numbers: CN212584520U, CN107654779A and CN107747657A; although the joint body can be fixed through the fixing holes on its side, the joint body is usually cylindrical, so when it contacts with the supporting surface, it is usually a line and surface contact, resulting in poor stability of the joint body when in use. Utility Model Content

[0003] The utility model aims to provide a double-tube elbow joint to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-tube elbow joint, comprising a joint body; a connecting portion is provided on the bottom surface of the joint body, and the side of the connecting portion facing the supporting surface is a plane; an installation groove is also provided on the side surface of the connecting portion, and the installation groove is connected to a connecting piece, and is connected to the supporting surface after a fastener passes through the connecting piece to fix the joint body on the supporting surface.

[0005] As a preferred technical solution of the utility model: the number of the connecting parts is two, and they are symmetrically arranged on the bottom surface of the joint body.

[0006] As a preferred technical solution of the present utility model: a connecting hole is provided on the end surface of the connecting portion.

[0007] As a preferred technical solution of the present utility model: the connecting portion is cylindrical.

[0008] As a preferred technical solution of the utility model: threads are provided on the inner wall surface of the connecting hole.

[0009] As a preferred technical solution of the present utility model: the connecting piece is plate-shaped.

[0010] By adopting the above technical solution, the beneficial effects of the utility model are as follows: 1. Due to the setting of the connecting part, the joint body can be in contact with the supporting surface through the end face of the connecting part, so that the joint body and the supporting surface are in surface-to-surface contact. Therefore, compared with the prior art in which the joint body and the supporting surface are in line and surface contact, the contact surface of the device is larger, thereby making the joint body more stable when in use;

[0011] 2. Due to the setting of the installation groove, the bolts are passed through the connecting piece on the installation groove and connected to the support surface, so the contact point between the joint body and the support surface can be further expanded by using the mutual cooperation between the connecting piece and the installation groove; thus, the stability of the joint body after being connected to the support surface can be further improved;

[0012] 3. Since the device directly sets the connection part on the joint body, by optimizing the external structure of the joint body, the normal operation of the joint body can be ensured while the joint body can be made more stable and reliable after being fixed.

[0016] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0017] See also Figure 1-2 The utility model provides an embodiment: a double-tube elbow joint, including a joint body 1; a connecting portion 5 is provided on the bottom surface of the joint body 1, and the side of the connecting portion 5 facing the supporting surface is a plane; a mounting groove 3 is also provided on the side of the connecting portion 5, and the mounting groove 3 is connected to a connecting piece 2 provided, and is connected to the supporting surface after passing through the connecting piece 2 by a fastener to fix the joint body 1 on the supporting surface.

[0018] In summary, due to the arrangement of the connection portion 5, the joint body 1 can contact the support surface through the end surface of the connection portion 5, thereby achieving surface-to-surface contact between the joint body 1 and the support surface. Therefore, compared with the prior art in which the joint body and the support surface are in line and surface contact, the contact surface of the device is larger, thereby making the joint body more stable when in use.

[0019] At the same time, due to the setting of the installation groove 3, the bolt passes through the connecting piece 2 on the installation groove 3 and is connected to the support surface, so the mutual cooperation between the connecting piece 2 and the installation groove 3 can be used to further expand the contact point between the joint body 1 and the support surface; thereby, the stability of the joint body after being connected to the support surface can be further improved;

[0020] In addition, since the device directly sets the connection part 5 on the joint body 1, by optimizing the external structure of the joint body 1, the joint body 1 can be made more stable and reliable after being fixed while ensuring the normal operation of the joint body 1.

[0021] Furthermore, since there are two connecting parts 5 and they are symmetrically arranged on the bottom surface of the connector body 1, when the connecting piece 2 is inserted into the mounting groove 3 between the two connecting parts 5, the stability of the connecting piece 2 when connected to the connector body 1 can be further improved.

[0022] Based on the above scheme, since a connecting hole 4 is provided on the end face of the connecting portion 5, when one end of the fastener passes through one side of the supporting surface and is connected to the connecting hole 4, the joint body 1 can be installed and fixed without using the connecting member 2.

[0023] Specifically, the connecting portion 5 is cylindrical, and a thread is provided on the inner wall surface of the connecting hole 4. Therefore, the connection method between the connecting hole 4 and the fastener is simpler and more convenient.

[0024] Furthermore, since the connecting member 2 is in the shape of a plate, the connecting member 2 is in surface contact between the supporting surfaces and between the connecting member 2 and the mounting groove 3, so as to improve the stability of the device when in use; in addition, the connecting member 2 is preferably an iron sheet.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
