Description

Technical Field

[0001] This utility model relates to the field of CT equipment technology, specifically to a horizontal cantilever CT equipment. Background Technology

[0002] CT, or computed tomography, uses precisely collimated X-ray beams, gamma rays, ultrasound, etc., along with highly sensitive detectors, to scan the object being measured section by section. It features fast scanning time and clear images.

[0003] When a CT scanner is in operation, the radiation it produces can be harmful to surrounding objects, especially living beings. Currently, when objects are placed on the cantilever in front of the CT scanner, there are safety hazards because the cantilever is fixed and close to the scanner. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A horizontal cantilever CT scanner includes a detection mechanism and a rotation mechanism. The detection mechanism includes a main body, a lower cantilever located at the front of the main body, an upper cantilever that fits against the top of the lower cantilever, and an extension cantilever slidably connected to the upper cantilever. The rotation mechanism includes two springs connected between the upper cantilever and the extension cantilever, a pull rope and a pressure rod connected to the extension cantilever, a tactile switch installed inside the upper cantilever, and a motor electrically connected to the tactile switch. The pull rope slides through the front end of the upper cantilever, the tactile switch is located in front of the pressure rod, and the motor is embedded in the top of the lower cantilever.

[0007] By adopting the above technical solution, pulling the pull rope causes the extension arm to retract into the upper arm. The pressure rod moves accordingly and presses the touch switch. Then, the motor drives the upper arm and the extension arm to rotate. The limit mechanism on the extension arm moves to the front of the lower arm. Then, by continuing to pull the pull rope, the upper arm and the extension arm can rotate back to the initial position. The main body of the equipment detects the item. The operator can place the item on the extension arm while staying away from the main body of the equipment, thereby preventing the main body of the equipment from affecting the operator's body.

[0008] In a preferred embodiment, the present invention can be further configured such that: an opening is provided at the top of the upper cantilever, and the pressure rod and the tactile switch are both located at the bottom of the opening.

[0009] In a preferred embodiment, the present invention can be further configured such that two springs are located on both sides of the pull rope, and the diameter of the springs is smaller than the thickness of the extended cantilever.

[0010] In a preferred embodiment, the present invention can be further configured such that: the top of the extended cantilever is provided with a limiting mechanism, the limiting mechanism including two guide rods connected to the top of the extended cantilever, a plurality of clamps slidably connected between the two guide rods, and a second spring sleeved on one end of the guide rod, the second spring being in contact with a clamp away from the pressure rod.

[0011] In a preferred embodiment, the present invention can be further configured such that multiple clamps are suspended above the top of the extended cantilever, the clamps being made of metal.

[0012] In a preferred embodiment, the present invention can be further configured such that the guide rod is H-shaped and the diameter of the second spring is smaller than the width of the outer end of the guide rod.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, pulling the pull rope causes the extension cantilever to retract into the upper cantilever. The pressure rod moves accordingly and presses the touch switch. Then, the motor drives the upper cantilever and the extension cantilever to rotate. The limiting mechanism on the extension cantilever moves to the front of the lower cantilever. Then, by continuing to pull the pull rope, the upper cantilever and the extension cantilever can rotate back to the initial position. The main body of the equipment detects the item. The operator places the item on the extension cantilever while away from the main body of the equipment, thereby preventing the main body of the equipment from affecting the operator's body.

[0015] 2. In this utility model, multiple clamping plates are pressed by spring two, and the distance between the multiple clamping plates can be flexibly adjusted to ensure that the multiple clamping plates can clamp items of any size. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes some embodiments of the horizontal cantilever CT device provided by this utility model with reference to the accompanying drawings.

[0028] Example 1:

[0029] Combination Figure 1-5 As shown, the horizontal cantilever CT device provided by this utility model includes a detection mechanism 100 and a rotation mechanism 200. The detection mechanism 100 includes a device body 110, a lower cantilever 120 disposed on the front side of the device body 110, an upper cantilever 130 attached to the top of the lower cantilever 120, and an extension cantilever 140 slidably connected to the upper cantilever 130.

[0030] The rotating mechanism 200 includes two springs 210 connected between the upper cantilever 130 and the extension cantilever 140, a pull rope 220 and a pressure rod 230 connected to the extension cantilever 140, a tactile switch 240 installed inside the upper cantilever 130, and a motor 250 electrically connected to the tactile switch 240. The pull rope 220 slides through the front end of the upper cantilever 130, the tactile switch 240 is located in front of the pressure rod 230, and the motor 250 is embedded in the top of the lower cantilever 120.

[0031] Furthermore, two springs 210 are located on both sides of the pull rope 220. The diameter of the springs 210 is smaller than the thickness of the extension cantilever 140. The layout design of the springs 210 ensures that the extension cantilever 140 will not get stuck when it retracts.

[0032] Example 2:

[0033] Combination Figure 1 , 2 and Figure 4As shown, based on Embodiment 1, the upper cantilever 130 has an opening at the top, and the pressure rod 230 and the tactile switch 240 are both located at the bottom of the opening. The opening is provided so that the operator can see the pressure rod 230 contacting the tactile switch 240, so that the operator can be alerted when the motor 250 is working.

[0034] Example 3:

[0035] Combination Figure 1 and Figure 5 As shown, in the above embodiment, the top of the extended cantilever 140 is provided with a limiting mechanism 300. The limiting mechanism 300 includes two guide rods 310 connected to the top of the extended cantilever 140, a plurality of clamping plates 320 slidably connected between the two guide rods 310, and a second spring 330 sleeved on one end of the guide rods 310. The second spring 330 is in contact with a clamping plate 320 away from the pressure rod 230. By pressing the multiple clamping plates 320 with the second spring 330, the distance between the multiple clamping plates 320 can be flexibly adjusted to ensure that the multiple clamping plates 320 can clamp items of any size.

[0036] Furthermore, multiple clamping plates 320 are suspended at the top of the extension cantilever 140. The clamping plates 320 are made of metal material, which can firmly clamp the items. Moreover, because they are suspended at the top of the extension cantilever 140, the clamping plates 320 can move flexibly.

[0037] Furthermore, the guide rod 310 is H-shaped, and the diameter of the second spring 330 is smaller than the width of the outer end of the guide rod 310. The size design of the second spring 330 can prevent the second spring 330 from falling off the guide rod 310.

[0038] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the operator pulls the pull rope 220, causing the extension arm 140 to retract into the upper arm 130. The spring 210 contracts to provide retraction space for the extension arm 140. Then the pressure rod 230 moves accordingly. After the pressure rod 230 contacts the tactile switch 240, the motor 250 drives the upper arm 130 and the extension arm 140 to rotate. Here, since the pull rope 220 is long enough, the end of the pull rope 220 will not move due to the rotation of the upper arm 130. Then the limiting mechanism 300 on the extension arm 140 moves to the front of the lower arm 120. The operator places the item on the extension arm 140 while away from the main body of the equipment 110, thereby preventing the main body of the equipment 110 from affecting the operator's body.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
