[0027] The following will be described in more detail with reference to the schematic diagram of the reactor fixing tool of the present invention, wherein the preferred embodiment of the present invention is shown, and it should be understood that the present invention described herein can be modified by a person skilled in the art, and still achieve the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to a person skilled in the art, and not as a limitation to the present invention.

[0028] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0029] like Figures 1 to 3 As shown, the embodiment of the utility model provides a reactor fixing tool, including a loading box 1, a sealing cover 2 and an elastic limiting hinge 18.

[0030] Specifically, a containing cavity 3 is provided in the loading box 1 , and a loading window is provided at an end of the loading box 1 .

[0031] The sealing cover 2 is movably installed at the loading window through an elastic limiting hinge 18, and the sealing cover 2 is used to seal the loading window.

[0032] In this embodiment, the elastic limiting hinge 18 has a first state and a second state, and when the elastic limiting hinge 18 is in the first state and the second state, it corresponds to the closed state and the open state of the sealing cover 2, respectively, specifically:

[0033] When the elastic limiting hinge 18 is in the first state, the elastic limiting hinge 18 pushes the sealing cover 2 to rotate toward the loading window side, and finally the sealing cover 2 fits with the loading window to achieve the sealing operation of the loading box 1.

[0034] When the elastic limiting hinge 18 is in the second state, during the opening process of the sealing cover 2, the elastic limiting hinge 18 limits and locks the sealing cover 2 so that it cannot rotate, and the sealing cover 2 remains in the open state.

[0035] In a specific embodiment, two sealing covers 2 are provided, and the two sealing covers 2 are symmetrically distributed on the loading window.

[0036] In addition, a detection window 5 is provided through the sealing cover 2. The detection window 5 is mainly used for passing the cable for detecting the reaction parameters in the reactor. At the same time, it is convenient for the operator to open the sealing cover 2. In order to reduce the scratches caused by the sharp edge of the detection window 5 to the cable and the operator, the edge of the detection window 5 has a rounded structure.

[0037] Furthermore, the elastic limiting hinge 18 includes a main hinge 6 and a secondary hinge 7, and the main hinge 6 and the secondary hinge 7 are rotatably connected via a pin shaft 8. A torsion spring 9 is arranged between the main hinge 6 and the secondary hinge 7, and the torsion spring 9 is sleeved on the pin shaft 8. The torsion spring 9 is located in the middle of the pin shaft 8, and a limiting member is also arranged between the main hinge 6 and the secondary hinge 7.

[0038] Specifically, the main hinge 6 and the secondary hinge 7 are installed at the edge of the sealing cover 2 and the loading window, respectively. When the limiting member releases the limiting of the main hinge 6 and the secondary hinge 7, the main hinge 6 and the secondary hinge 7 are separated under the elastic force of the torsion spring 9, thereby pushing the sealing cover 2 to fit the edge of the loading window, thereby achieving a sealing operation.

[0039] When the sealing cover 2 needs to be opened, the sealing cover 2 is rotated. At this time, the angle between the main hinge 6 and the auxiliary hinge 7 gradually decreases, and finally the limiting member limits the main hinge 6 and the auxiliary hinge 7. At this time, the angle between the main hinge 6 and the auxiliary hinge 7 remains constant, and the sealing cover 2 is in an open state.

[0040] The limiting member includes a limiting strip 10 and a limiting buckle, and the limiting strip 10 is snap-connected with the limiting buckle, and the limiting strip 10 and the limiting buckle are respectively arranged on the main hinge 6 and the auxiliary hinge 7 .

[0041] Specifically, the limit buckle includes a mounting tube 11, an adjustment seat 12 is threadedly installed on the inner wall of one end of the mounting tube 11, a clamping head 14 is elastically installed on the inner bottom surface of the adjustment seat 12 through a compression spring 13, and a clamping hole 15 matching the clamping head 14 is provided on the limit strip 10.

[0042] During the process of opening the sealing cover 2, the limit strip 10 rotates toward the limit buckle. When the sealing cover 2 is opened to a certain angle, the clamping head 14 is inserted into the clamping hole 15. The cooperation between the clamping head 14 and the clamping strip limits the relative rotation between the main hinge 6 and the auxiliary hinge 7. The sealing cover 2 remains in the open state, and the reactor can be taken in and put in at this time.

[0043] In a specific embodiment, in order to limit the separation of the clamping head 14 from the mounting tube 11, a limiting ring 16 is provided at one end of the mounting tube 11 away from the adjustment seat 12. In addition, a positioning piece 17 is provided below the end of the mounting tube 11 close to the clamping head 14, and when the limiting strip 10 is located between the clamping head 14 and the positioning piece 17, the clamping head 14 is clamped into the clamping hole 15. The provision of the positioning piece 17 can reduce the deformation of the end of the limiting strip 10 close to the clamping head 14, thereby ensuring the stable limiting of the sealing cover 2 by the limiting member when the sealing cover 2 is in the open state.

[0044] It should be noted that when the clamping force of the clamping head 14 on the limiting strip 10 is reduced and the limiting function cannot be performed,

[0045] The adjusting seat 12 is rotated to move the adjusting seat 12 toward the compression spring 13 . At this time, the compression amount of the compression spring 13 increases, and the pressure of the compression spring 13 on the clamping head 14 increases, so that the limiting strip 10 can be clamped.

[0046] In addition, the clamp head 14 is spherical near one end of the limit strip 10, and the limit strip 10 is clamped by the pressure of the compression spring 13 on the clamp head 14. At the same time, when the sealing cover 2 is closed, the sealing cover 2 is pushed to separate the limit strip 10 from the clamp head 14, completing the sealing operation of the sealing cover 2.

[0047] Compared with the prior art, the utility model has at least the following beneficial effects:

[0048] The utility model realizes the movable installation of the sealing cover by utilizing elastic limiting hinges, and can make the sealing cover be in a stable closed state and an open state at the same time, so that the reactor can be conveniently and quickly placed and taken out, which greatly improves the efficiency of taking and placing the reactor, and is convenient for operators to work, and has the characteristics of simple structure and convenient operation.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
