Metal detector distance adjusting mechanism

Abstract

This invention provides a metal detector distance adjustment mechanism, relating to the technical field of distance adjustment mechanisms, comprising: a base; on one hand, when placed, two support blocks can be unfolded, which improves the stability of the base during placement and prevents the device from tipping over during use; on the other hand, locking the unfolded support blocks can be achieved simply by rotating the adjusting screw rod. Rotating the adjusting screw rod enables synchronous locking of the two connecting rods, thus completing the synchronous locking of the unfolded support blocks, saving time and solving the problem that when using a metal detector, adjustments are needed due to the patient's height and weight. While existing distance adjustment mechanisms can be adjusted, they are limited in two ways: firstly, emergency distance adjustment is impossible when the driving component is damaged; secondly, they cannot enhance the warning effect or clean the warning light during distance adjustment.

Description

Technical Field

[0001] This invention relates to the field of distance adjustment mechanism technology, and in particular to a metal detection distance adjustment mechanism. Background Technology

[0002] Magnetic resonance imaging (MRI) is a common examination in radiology clinics. Patients cannot wear metal objects during an MRI scan. Wearing metal objects can interfere with the imaging process, resulting in unclear images and hindering diagnosis. Furthermore, the strong magnetic force generated during the MRI scan can cause metal objects to shift, potentially causing accidental injury to the patient. Therefore, a metal detector is necessary to detect these objects.

[0003] When using a metal detector, the distance needs to be adjusted due to the different heights and weights of patients. Although the existing distance adjustment mechanism can be adjusted, it cannot perform emergency distance adjustment when the drive component used for adjustment is damaged. Furthermore, it cannot enhance the warning effect or clean the warning light during distance adjustment. Summary of the Invention

[0004] In view of this, the present invention provides a metal detection distance adjustment mechanism, which solves the problem that when a metal detector is used for detection, the distance needs to be adjusted due to the different heights and weights of the patients. Although the distance adjustment mechanism of the existing device can be adjusted, on the one hand, it cannot be adjusted in an emergency when the drive component used for adjustment is damaged, and on the other hand, it cannot enhance the warning effect or clean the warning light during distance adjustment.

[0005] The purpose and effect of the metal detection distance adjustment mechanism of the present invention are achieved by the following specific technical means:

[0006] This invention provides a metal detection distance adjustment mechanism, specifically including: a base;

[0007] The base is equipped with a first adjustable distance section.

[0008] Preferably, the first adjustable part is composed of a sliding frame, an auxiliary block, a second connecting block, a threaded rod, a first motor, a rotating shaft, an impeller, a gear, and a gear rack. The sliding frame is welded to the top surface of the base. An auxiliary block is slidably connected to the sliding frame. The auxiliary block is a rectangular block structure. Two second connecting blocks are slidably connected to the auxiliary block. Both second connecting blocks are rectangular block structures. Two screws for locking the two second connecting blocks are threaded onto the auxiliary block.

[0009] Preferably, two first motors are installed on the sliding frame, and a threaded rod is installed on the rotating shaft of each first motor. The two threaded rods are respectively threadedly connected to two second connecting blocks. When it is necessary to adjust the vertical position of the metal detector, either first motor can be directly controlled to rotate. When the first motor rotates, it can drive the threaded rod to rotate. When the threaded rod rotates, the height of the second connecting block can be adjusted, thus realizing the height adjustment of the second adjustment part and the metal detector. During the adjustment process, if the threaded rod is damaged, the screw used to lock the second connecting block of the corresponding threaded rod is tightened, and then the other locking screw is released. At this time, the other first motor can be controlled to rotate.

[0010] Preferably, an alarm light is installed on the top of the sliding frame; a rotating shaft is rotatably connected to the sliding frame, the rotating shaft is a cylindrical rod structure, an impeller is installed on the rotating shaft, the impeller is aligned with the alarm light, and the blades on the impeller are polished to have a reflective effect.

[0011] Preferably, a gear is installed on the rotating shaft; a toothed rack is welded on the auxiliary block, and the toothed rack meshes with the gear. During the up-and-down adjustment of the metal detector, the rotation of the rotating shaft and the impeller can be achieved through the meshing transmission of the toothed rack and the gear. At this time, the wind force generated by the impeller can achieve wind cleaning of the warning light, and the reflection of the blades can expand the alarm effect.

[0012] Preferably, the auxiliary block is equipped with a second adjustable part, which consists of a mounting arm, an adjusting rod, a mounting base, a metal detector, and a second motor. There are two mounting arms, both of which are L-shaped structures. The two mounting arms are respectively welded to the left and right end faces of the auxiliary block.

[0013] Preferably, an adjusting rod is rotatably connected to the two auxiliary blocks, and a second motor is installed on the right auxiliary block, with the rotating shaft of the second motor connected to the adjusting rod.

[0014] Preferably, the left and right ends of the adjusting rod are threadedly connected to two mounting seats respectively, and the thread directions of the left and right ends of the adjusting rod are opposite. A metal detector is installed on the inner side of each of the two mounting seats. When it is necessary to adjust the distance between the two metal detectors, the second motor can be directly controlled to rotate. When the second motor rotates, it can drive the adjusting rod to rotate. At this time, under the drive of the adjusting rod, the two mounting seats can move synchronously in opposite directions, thus realizing the synchronous and rapid adjustment of the two metal detectors in opposite directions.

[0015] Preferably, a support portion is installed on the base, which consists of a connecting rod, a support block, a locking rod, a first connecting block, and an adjusting screw. Two connecting rods are slidably connected to the left and right end faces of the base. The right end of the two connecting rods on the left is welded to one support block, and the right end of the two connecting rods on the right is welded to another support block. The bottom end face of the support block is flush with the bottom end face of the base. The connecting rods and the support block together form an adjustable support structure for the base.

[0016] Preferably, the front end face of the base is slidably connected with two locking rods, both of which are cylindrical rod-shaped structures. The front end of each locking rod is welded to the first connecting block, and the rear end of each locking rod is in contact with the outer wall of the two front connecting rods respectively. The first connecting block is a rectangular block structure.

[0017] Preferably, an adjusting screw is rotatably connected to the front end face of the base. The adjusting screw is threaded onto the first connecting block. When the adjusting screw is rotated, the first connecting block is in a moving state. When supporting, first loosen the adjusting screw, and then unfold the two supporting blocks to the left and right respectively. After unfolding, tighten the adjusting screw. When the adjusting screw is tightened, the first connecting block and the two locking rods move backward under the drive of the adjusting screw. Locking is completed by the two locking rods pressing against the two connecting rods.

[0018] Preferably, an anti-slip block is attached to the top surface of the base. The anti-slip block is made of rubber and is a stepping structure for personnel. During use, personnel need to step on the anti-slip block to prevent them from slipping.

[0019] Preferably, the top surface of the anti-slip block is provided with protrusions in a linear array. The protrusions are semi-cylindrical structures. The linear array of protrusions together form an anti-slip structure when people step on it, which can further prevent slipping when people's feet come into contact with the protrusions.

[0020] The present invention has the following beneficial effects

[0021] The device is equipped with a support section. This support section serves two purposes: firstly, during placement, the two support blocks can be unfolded, improving the stability of the base and preventing the device from tipping over during use; secondly, locking the unfolded support blocks is achieved simply by rotating the adjusting screw rod. Rotating the adjusting screw rod synchronously locks the two connecting rods, thus completing the synchronous locking of the unfolded support blocks and saving time.

[0022] The device is equipped with a first adjustable section. This section allows for two functions: firstly, it enables the vertical movement of two metal detectors, facilitating a full-body search of personnel. During adjustment, if the threaded rod or the first motor is damaged, it can be adjusted using the other first motor and threaded rod, ensuring temporary functionality. Repairs can be performed after the inspection is complete, without disrupting normal operation. Secondly, while performing vertical detection, it also drives the impeller to rotate. The impeller's rotation cleans the warning light and reflects it, expanding the detection range and improving the warning effect.

[0023] The device is equipped with a second adjustment section, which enables synchronous reverse adjustment of the two metal detectors via a reverse thread drive, resulting in high adjustment efficiency. Attached Figure Description

[0038] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0039] Example 1:

[0040] Please refer to Figures 1 to 9 :

[0041] This invention proposes a metal detection distance adjustment mechanism, comprising: a base 1;

[0042] The first adjustable part 3 is installed on the base 1.

[0043] The first adjustable section 3 is composed of a sliding frame 301, an auxiliary block 302, a second connecting block 303, a threaded rod 304, a first motor 305, a rotating shaft 306, an impeller 307, a gear 308, and a gear rack 309. The sliding frame 301 is welded to the top surface of the base 1. An auxiliary block 302 is slidably connected to the sliding frame 301. The auxiliary block 302 is a rectangular block structure. Two second connecting blocks 303 are slidably connected to the auxiliary block 302. Both second connecting blocks 303 are rectangular block structures. Two screws for locking the two second connecting blocks 303 are threadedly connected to the auxiliary block 302.

[0044] The sliding frame 301 is equipped with two first motors 305. Each first motor 305 has a threaded rod 304 mounted on its rotating shaft. The two threaded rods 304 are threadedly connected to two second connecting blocks 303 respectively. When the metal detector 404 needs to be adjusted in height, either first motor 305 can be directly controlled to rotate. When the first motor 305 rotates, it can drive the threaded rod 304 to rotate. When the threaded rod 304 rotates, the height of the second connecting block 303 can be adjusted, thus achieving the height adjustment of the second adjustment part 4 and the metal detector 404. During the adjustment process, if the threaded rod 304 is damaged, the screw corresponding to the threaded rod 304 used for locking the second connecting block 303 is tightened, and then another locking screw is released. At this time, the other first motor 305 can be controlled to rotate.

[0045] The sliding frame 301 has an alarm light 5 installed on its top. A rotating shaft 306 is rotatably connected to the sliding frame 301. The rotating shaft 306 is a cylindrical rod structure. An impeller 307 is installed on the rotating shaft 306. The impeller 307 is aligned with the alarm light 5. The blades on the impeller 307 are polished and have a reflective effect after polishing.

[0046] A gear 308 is installed on the rotating shaft 306; a toothed rack 309 is welded on the auxiliary block 302. The toothed rack 309 meshes with the gear 308. During the up-and-down adjustment of the metal detector 404, the rotation of the rotating shaft 306 and the impeller 307 can be achieved through the meshing transmission of the toothed rack 309 and the gear 308. At this time, the wind force generated by the impeller 307 can achieve the air cleaning of the warning light 5, and the reflection of the blades can expand the alarm effect.

[0047] The auxiliary block 302 is equipped with a second adjustable part 4, which consists of a mounting arm 401, an adjusting rod 402, a mounting base 403, a metal detector 404, and a second motor 406. There are two mounting arms 401, both of which are L-shaped. The two mounting arms 401 are welded to the left and right end faces of the auxiliary block 302, respectively.

[0048] An adjusting rod 402 is rotatably connected to two auxiliary blocks 302. A second motor 406 is installed on one of the auxiliary blocks 302 on the right side, and the rotating shaft of the second motor 406 is connected to the adjusting rod 402.

[0049] The left and right ends of the adjusting rod 402 are threadedly connected to two mounting bases 403 respectively. The threads of the left and right ends of the adjusting rod 402 are in opposite directions. A metal detector 404 is installed on the inner side of each of the two mounting bases 403. When it is necessary to adjust the distance between the two metal detectors 404, the second motor 406 can be directly controlled to rotate. When the second motor 406 rotates, it can drive the adjusting rod 402 to rotate. At this time, under the drive of the adjusting rod 402, the two mounting bases 403 can move synchronously in opposite directions, thus realizing the synchronous and rapid adjustment of the two metal detectors 404.

[0050] The base 1 is equipped with a support part 2, which consists of a connecting rod 201, a support block 202, a locking rod 203, a first connecting block 204, and an adjusting screw 205. Two connecting rods 201 are slidably connected to the left and right ends of the base 1. The right end of the two connecting rods 201 on the left is welded to one support block 202, and the right end of the two connecting rods 201 on the right is welded to another support block 202. The bottom end of the support block 202 is flush with the bottom end of the base 1. The connecting rods 201 and the support block 202 together form the adjustable support structure of the base 1.

[0051] Among them, the front end face of the base 1 is slidably connected with two locking rods 203. Both locking rods 203 are cylindrical rod-shaped structures. The front end of each locking rod 203 is welded to the first connecting block 204. The rear end of each locking rod 203 is in contact with the outer wall of the two front connecting rods 201 respectively. The first connecting block 204 is a rectangular block structure.

[0052] The base 1 has an adjusting screw 205 rotatably connected to its front end. The adjusting screw 205 is threaded onto the first connecting block 204. When the adjusting screw 205 is rotated, the first connecting block 204 moves. When supporting, the adjusting screw 205 is loosened first, and then the two support blocks 202 are unfolded to the left and right respectively. After unfolding, the adjusting screw 205 is tightened. When the adjusting screw 205 is tightened, the first connecting block 204 and the two locking rods 203 move backward under the drive of the adjusting screw 205. The locking is completed by the two locking rods 203 pressing against the two connecting rods 201.

[0053] Example 2:

[0054] Based on Example 1, such as Figure 3 As shown, it also includes: anti-slip block 101. An anti-slip block 101 is attached to the top surface of the base 1. The anti-slip block 101 is made of rubber and is a stepping structure for personnel. When in use, personnel need to step on the anti-slip block 101. At this time, the anti-slip block 101 can prevent personnel from slipping.

[0055] Example 3:

[0056] Based on Example 2, such as Figure 3 As shown, it also includes: protrusions 102. The top surface of the anti-slip block 101 is provided with protrusions 102 in a linear array. The protrusions 102 are semi-cylindrical structures. The linear array of protrusions 102 together form an anti-slip structure when people step on it. When people's feet come into contact with the protrusions 102, it can further prevent them from slipping.

[0057] The specific usage and function of this embodiment are as follows:

[0058] During support, first loosen the adjusting screw 205, then unfold the two support blocks 202 to the left and right respectively. After unfolding, tighten the adjusting screw 205. When the adjusting screw 205 is tightened, the first connecting block 204 and the two locking rods 203 move backward under the drive of the adjusting screw 205. The locking is completed by the two locking rods 203 pressing against the two connecting rods 201. During use, personnel need to step on the anti-slip block 101 to prevent slipping. When the metal detector 404 needs to be adjusted up and down, simply control any one of the first motors 305 to rotate. When the first motor 305 rotates, it drives the threaded rod 304 to rotate. When the threaded rod 304 rotates, the height of the second connecting block 303 can be adjusted, thus achieving the height adjustment of the second adjusting part 4 and the metal detector 404. When the threaded rod 304 is damaged, the screw corresponding to the threaded rod 304 used for locking the second connecting block 303 is tightened, and then another locking screw is fed in. At this time, the other first motor 305 is controlled to rotate. During the up and down adjustment of the metal detector 404, the rotation of the shaft 306 and the impeller 307 can be realized through the meshing transmission of the gear row 309 and the gear 308. At this time, the wind force generated by the impeller 307 can realize the wind cleaning of the warning light 5, and the reflection of the blades can expand the alarm effect. When it is necessary to adjust the distance between the two metal detectors 404, the second motor 406 can be directly controlled to rotate. When the second motor 406 rotates, it can drive the adjusting rod 402 to rotate. At this time, under the drive of the adjusting rod 402, the two mounting bases 403 can be moved synchronously in opposite directions, thus realizing the synchronous and rapid adjustment of the two metal detectors 404 in opposite directions.
