In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.

Fig. 1 to 5 are exemplary structural views of a condition monitoring component mounting apparatus according to an embodiment of the present invention. Fig. 1 is a schematic view of a state monitoring element in an operating position, fig. 2 is a schematic view of the state monitoring element in a vertically flipped position, fig. 3 is an exploded view of a mounting device, and fig. 4 is an exploded view of a mounting base in the mounting device shown in fig. 3. Fig. 5 is a cross-sectional view of the assembled relationship of the horizontally drawn reset device of fig. 4. In the present embodiment, for convenience of description, the horizontal and vertical will be referred to in the following description based on the direction of the operation position of the condition monitoring element, i.e., the orientation shown in fig. 1. Of course, the horizontal direction may be referred to as a first direction, and the vertical direction may be referred to as a second direction perpendicular to the first direction.

Referring to fig. 1 to 5, a condition monitoring component mounting apparatus according to an embodiment of the present invention may include: a mounting base 100, a connecting plate 200, a vertical flip reset assembly 300 and a magnetic positioning member 400.

Wherein the mounting base 100 is for fixed mounting on a CT system. As shown in fig. 1 to 4, in the present embodiment, the mounting base 100 may include a fixed mounting block 110 and a horizontal pulling and restoring assembly, and in the present embodiment, the case where the horizontal pulling and restoring assembly includes two horizontal pulling and restoring members 120 is taken as an example. In practice, one or more than two may be included.

As shown in fig. 4, the fixed mounting block 110 has at least one horizontal sliding groove 111 and a vertical wall 112 at the end of each horizontal sliding groove 111. In the present embodiment, the case where there are two horizontal sliding grooves 111 is taken as an example. In practical application, there may be one or more than two. In addition, in this embodiment, the fixed mounting block 110 further has a wiring groove 113 thereon. The fixed mounting block 110 is configured to be fixedly mounted on the CT system, for example, the fixed mounting block 110 may have a mounting hole 114 thereon, and the fixed mounting block 110 may be fixed on a front cover bracket (not shown) of the CT system by a fastener through the mounting hole 114.

Each horizontally pulling reset device 120 is capable of translating between a first position and a second position in a horizontal direction. Wherein the first position (also referred to as reset position) corresponds to the working position of the condition monitoring element and the second position corresponds to the vertically flipped position of the condition monitoring element. As shown in fig. 4, in this embodiment, each horizontal pulling reset device 120 may comprise a horizontal slider 121, an elastic element 122 and a guiding fixture 123.

As shown in fig. 5, the horizontal slider 121 has a step-shaped through hole formed by a first radial dimension 1211 and a second radial dimension 1212, wherein the first radial dimension is larger than the second radial dimension; and the horizontal slider 121 is slidable between the first position and the second position within the horizontal sliding groove 111. In particular implementations, if the holes are circular holes, the radial dimension may be a diameter or a radius; if the hole is a regular polygonal hole, the radial dimension may be the diameter or radius of an inscribed circle or an circumscribed circle; if the holes are rectangular or other non-regular holes, the radial dimension may be described by the corresponding dimension.

The elastic element 122 has a radial dimension greater than said second radial dimension and can be housed in the first radial dimension hole 1211 of the horizontal slider 121.

The guiding and fixing member 123 has a limiting end 1231 and a fixing end 1232, the fixing end 1232 can pass through the stepped through hole of the horizontal sliding block 121 and is fixedly connected to the vertical wall 112 at the end of the corresponding horizontal sliding slot 111, the radial dimension of the limiting end 1231 is greater than the second radial dimension and smaller than the first radial dimension, and the elastic element 122 can be limited in the first radial dimension hole 1211. The guide fixture 123 simultaneously positions the horizontal slider 121 in the horizontal direction. In particular, the guiding fixture 123 may be a bolt or screw or a bolt-like member with a screw thread at only the tail end, or other elements capable of performing the above-mentioned functions.

The connection plate 200 is used to fixedly connect the state monitoring element 500. In this embodiment, the condition monitoring element 500 is assumed to be haliiel on the CT system.

The vertical turnover resetting component 300 is used for connecting the connecting plate 200 and the horizontal pulling resetting component respectively and can be switched between a horizontal working position and a vertical turnover position around the horizontal direction. The horizontal working position corresponds to the working position of the state monitoring assembly, and the vertical overturning position corresponds to the vertical overturning position of the state monitoring assembly.

In particular, the vertical flip reset assembly 300 can be implemented in a variety of ways. For example, a hinge assembly + hook assembly may be used, in which case the hinge assembly may be any hinge assembly such as a torque hinge assembly or the like that is switchable between a horizontal operative position and a vertically flipped position about a horizontal direction. For the case where there are two horizontally pulling reset members 120, the torque hinge assembly may also be two torque hinges. And the hook component is used for keeping the state monitoring component at a horizontal working position. The mounting position of the hook assembly can be determined according to the actual situation, for example, one end is fixed on the fixed mounting 110, and the other end is fixed on the connecting plate 200 or the hinge assembly. Alternatively, the vertically flipped reset assembly 300 may also take the form of a damped hinge. In the present embodiment, the vertical flip reset device 300 is illustrated as a damping hinge. As shown in fig. 3, the vertically flipped reset assembly 300 is a damped hinge assembly that enables hovering at any angle between the horizontal operating position and the vertically flipped position about the horizontal. In this embodiment, the damped hinge assembly includes two damped hinges 310, each damped hinge 310 being connected to the connecting plate 200 and one of the horizontally drawn return members 120, respectively. In the specific connection, there are various connection manners, for example, the

screw members

600, 700, 800, etc. shown in fig. 3 may be respectively used for fastening connection.

The magnetic positioning member 400 includes: a first magnetic element 410 and a second magnetic element 420. Wherein, the first magnetic element 410 is fixedly installed on the connection plate 200, and the second magnetic element 420 is fixedly installed on the installation base 100 at a position corresponding to the first magnetic element 410. Specifically, the second magnetic element 420 is fixedly mounted on the fixed mounting block 110. In particular, there are various connection methods, for example, fastening connection using the screw member 900 shown in fig. 3 and 4. The first magnetic element 410 and the second magnetic element 420 can be tightly engaged when the vertical flip reset assembly 300 is in the horizontal position. In particular, the first magnetic element 410 and the second magnetic element 420 may be magnet pieces with different polarities; alternatively, one may be a magnet and the other an iron.

In this embodiment, when the condition monitoring element haliiel is in the working position, i.e. as shown in fig. 1, the vertically-flipped reset component 300 is in the non-vertically-flipped reset position, i.e. the horizontal working position. When the haloiel and the system connection line need to be separated and connected, that is, as shown in fig. 2, the haloiel and the horizontal pulling and returning member 120 on the mounting base 100 are first pulled horizontally in a direction away from the fixed mounting block 110, so that the horizontal sliding block 121 is located at the second position, and at this time, the elastic element 122 is compressed due to the limiting effect of the guiding and fixing member 123 inside the horizontal pulling and returning member 120. Then, the vertically-flipping reset component 300 flips downward and overcomes the magnetic force of the magnetic positioning component 400, so that the haliiel is in the vertically-flipping position, and a large operation space is formed between the haliiel and the mounting base 100, which is convenient for directly completing the dismounting and mounting of the haliiel outside the front shell of the CT system without dismounting the front shell of the CT system. When the haliiel needs to be reset and is in a working state, the vertical turnover resetting component 300 is turned upwards to be in a horizontal working position, at this time, under the elastic force action of the elastic element 122 in the horizontal traction resetting component 120 and the magnetic force action of the magnetic positioning component 400, the horizontal traction resetting component 120 is in a resetting state, the horizontal sliding block 121 returns to the first position, and the haliiel returns to the working position.

An embodiment of the present invention further provides a CT system, which may include the state monitoring element mounting apparatus in any of the above embodiments.

Fig. 6 and 7 are schematic diagrams illustrating a CT system with a status monitoring component mounted thereon by using the status monitoring component mounting apparatus according to an embodiment of the present invention.

The right side in fig. 6 and 7 is a partially enlarged view of the state monitoring element mounting position region shown in the left side circle a. As shown in fig. 6 and 7, in the present embodiment, the condition monitoring component mounting device is fixed on a front shell cover plate bracket (not shown) of the CT system, i.e. still mounted on the upper portion of the CT system.
