[0017] In order to make the utility model patent purposes, technical scheme and advantages more clearly, the following is in conjunction with the drawings and examples, and the utility model is further detailed.The specific embodiments described here are merely used to explain the utility model, and are not used to limit the utility model.

[0018] In order to explain the technical scheme of the utility model, the following is explained by specific examples.

[0019] For the convenience of explanation, only the parts related to the utility model embodiments are shown.

[0020] In conjunction with Figures 1-4As shown, the fixing device comprises a workbench 1, the workbench 1 is provided with a stand 2, the side wall of the stand 2 is provided with a positioning seat 3, the left and right sides of the stand 2 corresponding to the positioning seat 3 are provided with clamping assemblies, the lower side corresponding to the positioning seat 3 is provided with a supporting assembly, the workbench 1 is provided with a fixing mechanism opposite to the positioning seat 3, the fixing mechanism comprises a fixing table 4, the fixing table 4 is provided with a fixing seat 5, the fixing seat 5 is provided with a sliding sleeve 6, the sliding sleeve 6 is provided with a sliding rod 7, the upper end of the sliding rod 7 is provided with a fixing bowl 8, the lower end of the sliding rod 7 penetrates through the fixing seat 5, the fixing seat 5 is provided with a support 10, the support 10 is rotatably provided with a push-pull rod 11, the lower end of the push-pull rod 11 is slidably connected with the tail of the sliding rod 7, the fixing seat 5 is provided with a locking mechanism for locking the sliding rod.

[0021] In the field of building construction, the pipe elbow as a key component for realizing fluid turning in the pipe system can be fixed by the fixing device to ensure the detection accuracy.

[0022] In the structure, as Figure 1 , the positioning seat 3 is provided with a positioning opening 12. When the pipe elbow is fixed by the device, first, one end of the pipe elbow is placed into the positioning opening, then the pipe elbow is rotated to make the other end of the pipe elbow face the fixing bowl. Then the supporting assembly supports the pipe elbow to form a preliminary support, and then the fixing mechanism is used to press the other end of the pipe elbow, and finally the clamping assembly clamps the pipe elbow to finally fix the pipe elbow.

[0023] Figure 3 In the structure, the lower end of the push-pull rod 11 has a notch 13, and a pair of waist round grooves 14 are formed on the lower end, the tail of the sliding rod 7 is located in the notch 13, and a pair of connecting columns 15 are formed on the sliding rod 7, the connecting columns 15 are slidably and limitingly installed in the same side of the waist round grooves 14.

[0024] When the fixing mechanism is used to press the pipe elbow, first, the push-pull rod is rotated, the lower end of the push-pull rod is upwardly rotated, the sliding rod moves upwardly in the sliding sleeve, and the fixing bowl moves upwardly to adhere to the end of the elbow. Then the locking mechanism is used to lock the sliding rod, and the fixing bowl always maintains the state of pressing the pipe elbow. In the above process, when the push-pull rod is rotated, the connecting column slides in the same side of the waist round groove.

[0025] As a preferred structure, as Figures 4-5 , the locking mechanism comprises a fixing shaft 15 installed in the fixing seat 5, a locking handle 16 penetrates into the fixing seat 5, the shaft of the locking handle 16 is a threaded rod, the end of the threaded rod is rotatably connected with the fixing shaft 15, a locking shaft 17 is sleeved on the threaded rod, and the fixing shaft 15 and the locking shaft 17 form an arc surface 18 corresponding to the sliding rod.

[0026] When the fixed bowl presses against the same side port of the pipe elbow, the rotating shaft is rotated using the rotating handle. During the rotation, the locking shaft moves toward the fixed shaft, and the arc surfaces of the fixed shaft and the locking shaft gradually clamp the slide rod, thus completing the locking of the slide rod.

[0027] In this device, such as Figures 1-2 The clamping assembly includes a clamping cylinder 19, a short block 20 on the clamping cylinder 19, and a clamping finger 21 rotatably mounted on the drive shaft of the clamping cylinder 19. The middle part of the clamping finger 21 is rotatably connected to the short block 20.

[0028] After the two ends of the pipe bend are clamped, the clamping assembly is used to clamp the pipe bend. At this time, the drive shaft of the clamping cylinder drives the tail of the clamping finger to rotate upward until the clamping finger presses the pipe bend tightly.

[0029] In addition, the support assembly includes a support cylinder 22, with its drive shaft facing upwards. When the support assembly is needed to support the pipe bend, the drive shaft of the support cylinder moves upwards a short distance until it supports the pipe bend.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
