[0029] In order for those skilled in the art to better understand the present application, the technical solutions of the present application are further described below in conjunction with the drawings and examples.

[0030] Among them, the drawings are only used for example, the representation is only a schematic diagram, and not a physical diagram, and cannot be understood as a limitation on the patent; in order to better illustrate the embodiments of the present application, some components of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings can be omitted; the same or similar components in the drawings of the embodiments of the present application correspond to the same or similar components; in the description of the present application, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, and not to indicate or imply that the device or element referred to must have a particular orientation, structure and operation, therefore, the terms describing the positional relationship in the drawings are only used for example, and cannot be understood as a limitation on the patent, for those skilled in the art, the specific meaning of the above terms can be understood according to the specific situation.

[0031] As shown in Figure 1 - Figure 4 The utility model discloses a ventilation duct structure convenient to install, including pipeline main body 1, joint block 2, pole piece 3 and locking piece, pipeline main body 1 is provided with at least one mounting bracket 4, and joint block 2 is placed below the top surface in mounting bracket 4.

[0032] Among them, pipeline main body 1 is provided with at least one mounting bracket 4, and joint block 2 is placed below the top surface in mounting bracket 4.

[0033] In order to make pipeline main body 1 more stable installation, the mounting bracket 4 can be provided with multiple, and is evenly distributed along the length direction of pipeline main body 1.

[0034] Among them, pole piece 3 is placed on the upper part of pipeline main body 1, and the pole piece 3 penetrates the upper end surface of mounting bracket 4, and is matched with joint block 2, and the other end of pole piece 3 is connected with the roof surface / ceiling, specifically, the pole piece 3 can adopt threaded connection or adopt the connection principle mode of expansion bolt with the roof surface, before installing the pipeline, through the preset pipeline main body 1 distribution path and length, the pole piece 3 is fixed at the corresponding position of the roof surface, and the multiple mounting brackets 4 are sleeved on the outer periphery of pipeline main body 1.

[0035] The operator can hold pipeline main body 1 with both hands, so that the bottom of pole piece 3 is matched with joint block 2.

[0036] The connecting block 2 has a positioning through hole 20 for the end of the rod-shaped member 3 to extend into, and the end of the rod-shaped member 3 is provided with a locking head 30.

[0037] After the locking head 30 engages with the positioning through hole 20, the rod-shaped member 3 is fixed to the upper part of the connecting block 2 under the action of the locking member.

[0038] By installing a mounting bracket 4 around the outer periphery of the pipe body 1, and using the cooperation between the rod-shaped component 3 and the connecting block 2, the mounting bracket 4 can be quickly fixed, thereby facilitating the installation and connection of the pipe body 1 to the wall.

[0039] Because of the locking head 30 and the positioning through hole 20, the mounting bracket 4 and the pipe body 1 can be installed or disassembled without additional tools, avoiding the problems of numerous, scattered, and easily lost parts that occur with traditional connection methods.

[0040] like Figure 2 , Figure 3 As shown, the locking head 30 has several protrusions 31 arranged upwards around its circumference.

[0041] Specifically, the bottom surface of the connecting block 2 is symmetrically provided with side ears 22 that cooperate with the protrusion 31.

[0042] The positioning through hole 20 has several guide grooves 21 extending axially on its peripheral wall.

[0043] During the process of the rod-shaped member 3 extending into the connecting block 2, the process is made smoother by the cooperation of the guide groove 21 and the protrusion 31. After the locking head 30 extends out of the other side of the connecting block 2, the protrusion 31 and the guide groove 21 are misaligned by twisting the connecting block 2. At this time, after the upward external force on the mounting bracket 4 is removed, the mounting bracket 4 is securely connected to the top surface / ceiling below by the rod-shaped member 3 through the cooperation of the connecting block 2 and the rod-shaped member 3.

[0044] This method requires no additional tools and is therefore more convenient to operate.

[0045] Based on the aforementioned ease of installation, in order to increase the reliability of installation and prevent the main body of the pipeline 1 from shaking during maintenance, which could cause the connecting block 2 to detach from the rod-shaped part 3, a locking component has been added, taking into account the characteristics of the above components.

[0046] Specifically, the locking element can take various structural forms, such as a retaining ring with a notch (not shown in the figure), including but not limited to a retaining spring. In addition, an annular groove 32 is provided between the locking head 30 and the main body of the rod-shaped element 3.

[0047] The rod-shaped member 3 is inserted into the annular clamping groove 32 through the clamping ring, and since the clamping ring is located at the lower end of the engaging block 2 and has a diameter larger than the hole diameter of the positioning through hole 20, the vertical freedom of the rod-shaped member 3 is limited, and the rod-shaped member 3 cannot be disengaged from the engaging block 2.

[0048] Another structure of the locking member can adopt a latch (not shown in the figure), which limits the relative rotation of the engaging block 2. Specifically, locking through holes 220 are formed on the protrusion 31 and the side lug 22, respectively. After the locking head 30 extends out of the engaging block 2 and rotates the engaging block 2 to misalign the protrusion 31 and the guide groove 21, the latch is inserted into the locking through holes 220 of the protrusion 31 and the side lug 22 when they are aligned, thereby avoiding rotation and overcoming the adverse effects caused by shaking.

[0049] The above is only an embodiment of the present application, and the common knowledge of the specific structure and characteristics in the scheme is not described in detail here. The ordinary skilled person in the art knows all the ordinary technical knowledge in the technical field of the present application before the filing date or the priority date, can know all the prior art in this field, and has the ability to apply conventional experimental means before that date. The ordinary skilled person in the art can improve and implement this scheme based on their own ability under the guidance of this application. Some typical known structures or known methods should not be an obstacle for the ordinary skilled person in the art to implement this application. It should be noted that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered within the protection scope of the present application. These will not affect the effectiveness and practicality of the implementation of the present application.
