Technical Field
[0001] This utility model relates to the field of educational toys, specifically to a main frame for a children's mine detector. Background Technology
[0002] Metal detectors, as educational toys that can stimulate children's curiosity and exploratory spirit, are widely popular in the market. Existing children's metal detectors or mine detector toys usually mimic the handheld devices used by adults in terms of structure. Their structure mainly consists of a handle that integrates control, display and grip, with the handle connected to a long rod, and a detection coil set at the end of the long rod.
[0003] However, such traditional structures have the following drawbacks when used by children: First, children have limited arm strength, and holding the entire detector for extended periods while sweeping through the surface requires them to continuously bear the full weight of the device, easily leading to fatigue and reducing the game's endurance. Second, the detection effectiveness of a metal detector is closely related to the height of its detection ring components above the ground. When using a handheld device, children find it difficult to maintain a stable detection height while moving, and constant changes in height affect the sensitivity and accuracy of the detection, reducing the exploration experience. Furthermore, when children need to rest or stop digging after discovering a target, handheld detectors are difficult to place; they are often simply thrown on the ground, easily causing wear and tear or damage to the equipment.
[0004] Therefore, how to design a mine detector main frame that is structurally sound, easy to use, and feature-rich, and that can stimulate children's interest in learning, is a technical problem that urgently needs to be solved in this field. Utility Model Content
[0005] The purpose of this utility model is to provide a main frame for a child mine detector, which can bear most of the weight through the bottom support unit, achieve height and pitch adjustment, have temporary anchoring and cleaning functions, and is easy to park stably and hold comfortably, thereby improving the child's user experience and playability.
[0006] The technical solution adopted by this utility model to solve the above problems is: a main frame of a child mine detector, including a grip body and a detection ring assembly. The grip body has a built-in controller and battery, and is electrically connected to the detection ring assembly. A support unit is provided at the bottom of the grip body. The support unit is used to adjust the height of the grip body and support its stable movement. It includes a moving body and a sliding rod. The lower end of the sliding rod is vertically slidably connected to the moving body, and the upper end is hinged to the bottom of the grip body.
[0007] Preferably, the mobile body includes a base plate, with symmetrically arranged movable wheel sets on the left and right sides of the base plate. A slide block is fixed above the base plate by four sets of vertical connecting rods. A locking component is provided above the slide block, which includes a threaded cylinder and a locking sleeve. The slide rod passes through the threaded cylinder and fits against the inner wall of the threaded cylinder. The upper end of the threaded cylinder has an external thread structure, and the end of the external thread structure has a notch. The locking sleeve is screwed into the threaded cylinder. When the locking sleeve is screwed toward the notch end, it squeezes the external thread structure of the threaded cylinder to fix the slide rod.
[0008] Preferably, the lower end of the slide bar is provided with a fixing part, which has a hollow structure. The side wall is provided with slots that are narrower at the top and wider at the bottom at equal intervals. Adjacent slots form a fork that is wider at the top and narrower at the bottom. The slide bar slides down and the fork is inserted into the ground for fixation.
[0009] Preferably, a cleaning component is detachably connected and fixed on the substrate. The cleaning component includes a cleaning block that matches the cross-sectional contour of the fixing part. The cleaning block has locking blocks evenly spaced around its outer periphery. The substrate has an installation groove that matches the cleaning block. The installation groove has a locking slot that matches the locking blocks around its periphery. A cover plate is provided above the cleaning block. The cover plate fixes the cleaning block to the substrate by threaded fasteners.
[0010] Preferably, the front end of the mobile body is provided with a baffle, which is detachably connected and fixed to the base plate by multiple sets of transverse connecting rods and threaded fasteners, and the baffle is provided with a bent top cover at an angle.
[0011] Preferably, the rear end of the mobile body is provided with a support assembly, which includes a support frame fixed to the base plate and a support plate hinged to the upper end of the support frame via a damping bushing. The gripping body swings downward along the hinge axis between the support frame and the upper end of the slide rod so that its bottom contacts the upper surface of the support plate for support and limitation.
[0012] Preferably, the grip body includes a fixed housing and an extension frame slidably connected to the fixed housing. A handle is detachably threaded onto the fixed housing. Two sets of support protrusions are symmetrically arranged on the left and right sides of the rear end of the extension frame. Flexible pads are provided on the upper surfaces of the extension frame and the support protrusions.
[0013] Compared with the prior art, this utility model has the following advantages and effects:
[0014] This invention transfers most of the mine detector's weight to the ground by incorporating a support unit with movable wheels. Children can easily control its movement with a simple push or pull, greatly reducing arm strain, extending playtime, and enhancing the fun of educational exploration. The use of a sliding rod and locking mechanism allows for precise adjustment and reliable fixation of the detection ring assembly above the ground to suit children of different heights, ensuring a constant height during detection and improving stability. Furthermore, this invention integrates a front baffle, rear parking support assembly, sliding rod cleaning assembly, and ground fixing function, transforming the product from a simple detection tool into a multifunctional mobile platform, optimizing the child's user experience in terms of dirt prevention and parking.

Detailed Implementation
[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0023] Example:
[0024] See Figure 1 - Figure 6 In this embodiment, a main frame for a child mine detector is disclosed. For safety reasons, this utility model is specifically designed for children to operate on flat ground without much vegetation (such as sand, lawn, etc.). Specifically, it includes a grip body 1 for children to hold and a detection coil assembly 2 for detection. The grip body 1 can be equipped with a conventional controller circuit board and battery, and is electrically connected to the detection coil assembly 2 via a cable. The detection coil assembly 2 includes a set of telescopic rods 21 with adjustable length and a detection coil 22. This part belongs to the prior art and will not be described in detail here.
[0025] The core innovation of this embodiment lies in the support unit located at the bottom of the gripping body 1. This support unit is used to adjust the height of the gripping body 1 and support its stable movement. The support unit is crucial for the effortless and convenient use of the entire device. It includes a movable body 3 and a sliding rod 4. The upper end of the sliding rod 4 is connected to the bottom of the gripping body 1 via a hinge shaft. This hinged connection allows children to easily adjust the pitch angle of the gripping body 1 and even the probe assembly 2 to adapt to different ground slopes. The lower end of the sliding rod 4 is vertically connected to the movable body 3, thereby achieving overall height adjustment.
[0026] Specifically, when children use it, they first determine the detection height by adjusting the extension length of the slider 4 according to their own height. Then, they hold the main body 1 and push the entire device to move it within the detection area. Most of the weight of the device is borne by the moving body 3. During movement, the pitch of the detection ring assembly 2 can be changed by adjusting the angle of the holding body 1 to adapt to the terrain. When a suspicious target is detected and it is necessary to pause, simply release the holding body 1. It is easy to use and can stimulate children's learning interest.
[0027] See Figure 2 and Figure 3The height locking structure of the moving body 3 and the slide rod 4 is described in detail. Specifically, the moving body 3 includes a base plate 31, on which multiple sets (two sets on each side in this embodiment) of moving wheels 32 are symmetrically installed to ensure smooth movement of the equipment. A slide block 34 is fixedly connected to the base plate 31 via four sets of vertical connecting rods 33. A locking element 35 for fixing the slide rod 4 is provided in the center of the slide block 34. The locking element 35 includes a threaded cylinder 351 and a locking sleeve 352. The slide rod 4 passes through the central hole of the threaded cylinder 351 and fits against the inner wall of the threaded cylinder 351. The upper outer wall of the threaded cylinder 351 is provided with external threads, and its end has one or more notches radially opened (not separately indicated in the figure). The locking sleeve 352 has an internal thread that mates with it. When the height needs to be adjusted, the locking sleeve 352 is loosened by unscrewing in the opposite direction. At this time, the notched end of the threaded cylinder 351 is in a relaxed state, and there is no clamping force on the slide rod 4, allowing the slide rod 4 to slide freely up and down. Once the appropriate height is reached, tighten the locking sleeve 352 clockwise. The locking sleeve 352 will move downwards along the thread, thereby squeezing the notched end of the threaded cylinder 351, causing it to contract and deform inwards, and then tightly gripping the slide rod 4, achieving reliable locking through friction.
[0028] See Figure 4 The lower end of the sliding rod 4 is provided with a fixing part 41, which has a hollow structure. Its side wall has equally spaced slots 411, narrower at the top and wider at the bottom, forming a fork 412 between adjacent slots. When a child needs to rest during exploration or stops digging after discovering a target, simply unlock the locking member 35 and drive the sliding rod 4 down. The fork-shaped structure at its lower end can then insert into the soft ground like a nail, temporarily anchoring the device and preventing it from sliding. This solves the problem that traditional handheld detectors are difficult to place and often have to be thrown on the ground, easily causing wear or damage. To facilitate equipment maintenance, a cleaning component 36 is detachably connected and fixed to the base plate 31. The cleaning component 36 includes a cleaning block 361 that matches the cross-sectional contour of the fixing part 41. The cleaning block 361 can be made of hard plastic. The cleaning block 361 has evenly spaced locking blocks 363 on its outer periphery. The base plate 31 has a mounting groove 364 that matches the cleaning block 361. The mounting groove 364 has circumferentially formed locking slots 365 that match the locking blocks 363. A cover plate 362 is provided above the cleaning block 361, and the cover plate 362 fixes the cleaning block 361 to the base plate 31 using threaded fasteners. The main function of this cleaning component 36 is to work in conjunction with the fixing part 41 of the slide rod 4. When the fixing part 41 is inserted into mud or sand, its interior and the slot 411 are easily clogged with mud and sand. Each time the slide rod 4 is raised, the fixing part 41 can be cleaned by the cleaning block 361 (some mud and sand residue does not affect use). The cleaning block 361 features a detachable connection structure, and when it needs to be replaced, simply open the cover plate 362.
[0029] In this embodiment, the front end of the mobile body 3 is provided with a baffle 37. The baffle 37 is detachably connected and fixed to the base plate 31 by multiple sets of transverse connecting rods 372 and threaded fasteners. The baffle 37 is provided with a bent top cover 371 at an angle. The baffle 37 can effectively block debris splashed up during movement in environments such as grass or sand, which can minimize the pollution of children's clothes by debris and provide better protection for children.
[0030] To address the issue of equipment parking, a support assembly 38 is provided at the rear end of the mobile body 3. This support assembly 38 includes a support frame 381 fixed to the base plate 31 and a support plate 382 hinged to the upper end of the support frame 381 via a damping bushing. The gripping body 1 swings downwards along the hinge axis connecting it to the upper end of the slide rod 4 until its bottom contacts and supports the upper surface of the support plate 382. The use of a damping bushing ensures a smooth flipping process for the support plate 382 and allows it to stop at any angle. When it is necessary to park and store the equipment, such as... Figure 5 As shown, the probe ring assembly 2 can be retracted, and then the gripping body 1 can be driven to swing backward and downward around its hinge point with the slide bar 4, so that its bottom rests on the support plate 382, thereby forming a stable triangular support structure, achieving stable storage and parking.
[0031] To improve operational comfort, the grip body 1 includes a fixed housing 11 and an extension frame 12 slidably connected to the fixed housing 11, accommodating different children's arm lengths. A handle 13 for easy gripping is detachably threaded onto the fixed housing 11. See also Figure 6 The extension frame 12 has two sets of support protrusions 14 symmetrically arranged on the left and right sides at the rear end. The upper surface of the extension frame 12 and the support protrusions 14 are provided with flexible pads 15 (which can be made of silicone or TPU), so that children can comfortably place their forearms on them and further reduce the pressure on their wrists.
[0032] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
