An installation chute 4 is opened inside one side of the elbow body 1. The elbow extension pipe 3 is located on one side of the elbow body 1, and the elbow extension pipe 3 is slidably connected to the installation chute 4. An insulating tape 5 is wound around the surface of the elbow extension pipe 3 and the surface of the installation chute 4.

[0031] First, confirm the installation distance between the elbow body 1 and the elbow extension pipe 3, then slide and snap the elbow extension pipe 3 into the installation chute 4 opened inside the elbow body 1 according to the confirmed distance. After that, the elbow body 1 and the elbow extension pipe 3 are clamped and fixed and thread-mounted through the installation assembly 2. Then, the installation position of the elbow body 1 and the elbow extension pipe 3, that is, the gap between the elbow extension pipe 3 and the installation chute 4, is wound with the insulating tape 5. The insulating tape 5 is used to seal and wind the elbow body 1 and the elbow extension pipe 3, and the viscosity of the insulating tape 5 is used in cooperation with the installation assembly 2 to improve the installation stability of the elbow body 1 and the elbow extension pipe 3, and the operation is simple.

[0032] By installing the sliding groove 4, it is convenient to make the elbow extension pipe 3 snap into the elbow body 1. At the same time, the installation spacing between the elbow extension pipe 3 and the elbow body 1 can be determined, which makes the installation spacing adjustable, improves the flexibility of the installation between the elbow body 1 and the elbow extension pipe 3. The installation component 2 facilitates the adjustable installation between the elbow body 1 and the elbow extension pipe 3, and the insulating tape 5 facilitates winding and sealing the installation gap between the elbow body 1 and the elbow extension pipe 3, preventing gaps from appearing at the joint positions of the elbow extension pipe 3 and the sliding groove 4, which may affect the subsequent overall use of the elbow body 1 and the elbow extension pipe 3.

[0033] In one embodiment, for the above installation component 2, the installation component 2 includes a fixing ring 201, an installation ring 202, two limiting slide bars 203, four positioning connection blocks 205, four positioning cylinders 207 and four outward expansion springs 210. The fixing ring 201 is arranged on the surface of the elbow extension pipe 3, the installation ring 202 is arranged on the surface of the elbow body 1, two limiting slide bars 203 are arranged on the installation ring 202, five card slots 204 are opened at the top and bottom of the two limiting slide bars 203, four positioning connection blocks 205 are all snap-fitted inside the fixing ring 201, positioning bolts 206 are threadedly connected to the inside of the four positioning connection blocks 205, four positioning cylinders 207 are respectively arranged on the surfaces of the four positioning connection blocks 205, inner rods 208 are slidably connected to the inside of the four positioning cylinders 207, one ends of the four inner rods 208 are all connected with clamping blocks 209, and four outward expansion springs 210 are respectively sleeved on the surfaces of the four positioning cylinders 207.

[0034] First, thread-mount all four positioning connection blocks 205 to the fixed ring 201 through positioning bolts 206. Then, confirm the installation spacing between the elbow body 1 and the elbow extension pipe 3. It should be noted here that it is defaulted that the required installation spacing between the elbow body 1 and the elbow extension pipe 3 meets the spacing of each card slot 204, that is, the five adjustable spacing requirements between the elbow body 1 and the elbow extension pipe 3 can be engaged with different card slots 204 to obtain corresponding results. And each card slot 204 is covered by a retaining cover (not shown in the figure and not specifically described, which does not affect the use) to prevent the clamping block 209 from engaging with a card slot 204 that does not meet the spacing requirements when moving. Then, describe the card slot 204 in the center, that is, the third card slot 204 from left to right. First, remove the retaining covers on the two central card slots 204. After the positioning connection block 205 has been installed to the fixed ring 201 through the positioning bolt 206 and the spacing between the elbow body 1 and the elbow extension pipe 3 is confirmed to make the clamping block 209 engage with the card slot 204 in the central position, hereinafter directly described as the card slot 204. Pull the elbow extension pipe 3 to the left, so that the elbow extension pipe 3 gradually slides into the installation chute 4, and the fixed ring 201 drives all four positioning cylinders 207, inner rods 208, clamping blocks 209 and outward expansion springs 210 to move leftward. After the clamping block 209 corresponds to the card slot 204, drive the inner rod 208 and the clamping block 209 to elastically pop out and engage with the corresponding card slot 204 through the elastic outward expansion of the outward expansion spring 210, thereby positioning the installation positions of the elbow body 1 and the elbow extension pipe 3. Finally, wind the insulating tape 5 around the external installation part between the elbow extension pipe 3 and the installation chute 4 to complete the installation between the elbow body 1 and the elbow extension pipe 3. Not only can the installation spacing between the elbow body 1 and the elbow extension pipe 3 be adjusted, but also the stability of the installation between the elbow body 1 and the elbow extension pipe 3 can be improved by winding the insulating tape 5, and the installation positions of the elbow body 1 and the elbow extension pipe 3 can be sealed to enhance the safety of use, and the operation is simple and convenient.

[0035] The card slot 204 facilitates meeting the installation requirements between the elbow body 1 and the elbow extension pipe 3. The inner rod 208 slidably arranged with the positioning cylinder 207 facilitates driving the clamping block 209 to pop out and engage with the corresponding card slot 204 under the elastic outward expansion of the outward expansion spring 210, realizing the adjustable distance between the elbow body 1 and the elbow extension pipe 3. And by providing a retaining cover on the card slot 204, it effectively prevents the clamping block 209 from engaging with a non-corresponding card slot 204, preventing errors in the distance adjustment between the elbow body 1 and the elbow extension pipe 3. And the positioning connection block 205 is installed with the fixing ring 201 through the positioning bolt 206, which is convenient for installation and also convenient for disassembly. The installation chute 4 facilitates the elbow extension pipe 3 to be inserted into the elbow body 1, and at the same time, the installation distance between the elbow extension pipe 3 and the elbow body 1 can be determined, improving the flexibility of the installation between the elbow body 1 and the elbow extension pipe 3. The insulating tape 5 facilitates winding and sealing the installation gap between the elbow body 1 and the elbow extension pipe 3, preventing the occurrence of gaps at the joint position between the elbow extension pipe 3 and the installation chute 4, which may affect the subsequent overall use of the elbow body 1 and the elbow extension pipe 3.

[0036] In addition, during specific application, each card slot 204 is covered by a retaining cover in advance (the retaining cover is not shown in the figure and no special description is made, which does not affect the use) to prevent the clamping block 209 from engaging with a card slot 204 that does not meet the distance requirement during movement.

[0037] In one embodiment, for the above-mentioned limiting slide rod 203, the surfaces of both of the two limiting slide rods 203 are slidably connected to the inner side of the fixing ring 201, so as to facilitate the fixing ring 201 to pass through the two limiting slide rods 203, and facilitate improving the stability of the movement of the fixing ring 201.

[0038] In one embodiment, for the above-mentioned positioning bolt 206, the surfaces of all four positioning bolts 206 are threadedly connected to the inner side of the fixing ring 201, so as to facilitate the installation and disassembly of the positioning connection block 205 and the fixing ring 201.

[0039] In one embodiment, for the above-mentioned clamping block 209, the four clamping blocks 209 are respectively engaged and connected with four of the card slots 204, so as to facilitate positioning after the distance between the elbow body 1 and the elbow extension pipe 3 is adjusted.

[0040] In one embodiment, for the above-mentioned outward expansion spring 210, the two ends of all four outward expansion springs 210 are respectively connected to the surfaces of the four positioning connection blocks 205 and the surfaces of the four clamping blocks 209, so as to facilitate driving the clamping block 209 to pop out and engage after corresponding to the card slot 204, and facilitate positioning the elbow body 1 and the elbow extension pipe 3.

[0041] In summary, by means of the above technical solution of the present utility model, first, the four positioning connection blocks 205 are all threadedly installed with the fixing ring 201 through the positioning bolts 206. Then, confirm the installation distance between the elbow body 1 and the elbow extension pipe 3. Here, it needs to be specifically stated that it is default that the required installation distance between the elbow body 1 and the elbow extension pipe 3 meets the distance of each card slot 204, that is, the five adjustable distance requirements between the elbow body 1 and the elbow extension pipe 3 can be engaged with different card slots 204 to obtain corresponding results. And each card slot 204 is covered by a retaining cover beforehand (not shown in the figure and no special description is made, which does not affect the use) to prevent the clamping block 209 from engaging with the card slot 204 that does not meet the distance requirement when moving. Then, describe the card slot 204 in the center, that is, the third card slot 204 from left to right. It is necessary to first remove the retaining covers on the two central card slots 204. After the positioning connection block 205 has been installed with the fixing ring 201 through the positioning bolt 206, and the distance between the elbow body 1 and the elbow extension pipe 3 is confirmed to make the clamping block 209 engage with the card slot 204 in the central position, hereinafter directly described as the card slot 204. Pull the elbow extension pipe 3 to the left, so that the elbow extension pipe 3 gradually slides into the installation chute 4. And the fixing ring 201 drives the four positioning cylinders 207, the inner rod 208, the clamping block 209 and the outward expansion spring 210 to move leftward. After the clamping block 209 corresponds to the card slot 204, the elastic outward expansion of the outward expansion spring 210 drives the inner rod 208 and the clamping block 209 to elastically pop out and engage with the corresponding card slot 204, thereby positioning the installation positions of the elbow body 1 and the elbow extension pipe 3. Finally, wrap the insulating tape 5 around the external installation between the elbow extension pipe 3 and the installation chute 4 to complete the installation between the elbow body 1 and the elbow extension pipe 3. Not only can the installation distance between the elbow body 1 and the elbow extension pipe 3 be adjusted, but also the stability of the installation between the elbow body 1 and the elbow extension pipe 3 can be improved by the wrapped insulating tape 5. And the installation positions of the elbow body 1 and the elbow extension pipe 3 can be sealed to improve the safety of use, and the operation is simple and convenient.

[0042] Through the above technical solutions: 1. The card slot 204 facilitates meeting the installation requirements between the elbow body 1 and the elbow extension pipe 3. The inner rod 208 slidably arranged with the positioning cylinder 207 facilitates driving the clamping block 209 to pop out and engage with the corresponding card slot 204 under the elastic outward expansion of the outward expansion spring 210, realizing the adjustable distance between the elbow body 1 and the elbow extension pipe 3. And by providing a retaining cover on the card slot 204, it effectively prevents the clamping block 209 from engaging with a non-corresponding card slot 204, preventing errors in adjusting the distance between the elbow body 1 and the elbow extension pipe 3. Moreover, the positioning connection block 205 is installed with the fixing ring 201 through the positioning bolt 206, which is convenient for installation and disassembly; 2. The installation chute 4 facilitates the elbow extension pipe 3 to be inserted into the elbow body 1, and at the same time, the installation distance between the elbow extension pipe 3 and the elbow body 1 can be determined, improving the flexibility of the installation between the elbow body 1 and the elbow extension pipe 3. The insulating tape 5 facilitates winding and sealing the installation gap between the elbow body 1 and the elbow extension pipe 3, preventing the occurrence of gaps at the joint position between the elbow extension pipe 3 and the installation chute 4, which may affect the subsequent overall use of the elbow body 1 and the elbow extension pipe 3.
