Description

TECHNICAL FIELD

[0001] The utility model relates to the field of toys, especially a seesaw track unit. BACKGROUND

[0002] Track toys are usually composed of multiple different track units, which can be freely combined into different complete tracks, effectively exercising children's hands-on ability and inspiring children's thinking. However, current track units generally have only limited types such as straight, with slope, or with curve, and the structures of these track units are relatively simple. Even if different complete tracks are formed by various combinations, the playability is still insufficient.

[0003] Currently, there are also track toys that use seesaw track units for combination, such as the track toy disclosed in CN217593811U on October 18, 2022. This track toy includes a seesaw track unit in the track body. The seesaw track unit includes a second base and an arc-shaped plate. The upper surfaces of the front and rear ends of the second base are respectively provided with guide rails. The rear end of the second base is provided with a first track connector, and the front end of the second base is provided with a second track connector. The upper surface of the arc-shaped plate is provided with a guide rail, and the front middle part of the lower surface of the arc-shaped plate is hinged to the second base. When a toy car moves onto the seesaw track unit from other track units, the toy car moves along the arc-shaped plate from back to front. When the toy car moves to the front part of the arc-shaped plate, the front part of the arc-shaped plate swings downward under the gravity of the toy car, causing the front end of the arc-shaped plate to contact the front end of the second base, and the toy car can smoothly pass through and advance to the next track unit. However, this seesaw track unit uses a hinge between the front middle part of the lower surface of the arc-shaped plate and the second base, so under the condition of no force, the arc-shaped plate can only be fixed in one direction. Therefore, when combining track units, it is necessary to determine the forward direction of the toy car in advance, and when adjusting the direction of the toy car, the seesaw track unit needs to be disassembled and reassembled, which is not only troublesome, but also frequent disassembly and assembly can cause the insertion part of the track unit to loosen or even be damaged. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a seesaw track unit that can adjust the initial direction of the seesaw at any time according to the direction of the toy car on the track, which is convenient and fast to operate.

[0005] To solve the above technical problems, the technical solutions adopted are as follows:

[0006] A seesaw track unit comprises a base and a seesaw body, the left and right ends of the base are respectively provided with track connecting pieces, and the upper surface of the seesaw body is provided with a first guide rail, characterized in that: the middle part of the seesaw body is movably connected with the base; the seesaw track unit further comprises a direction adjusting block, which is movably arranged on the base, and the direction adjusting block is provided with a supporting part, and the supporting part is in contact with the middle part of the seesaw body.

[0007] When the above-mentioned seesaw track unit is used, the base is connected with other track units through the track connecting pieces. After assembly is completed, according to needs, the direction adjusting block can be moved to the moving direction of the toy car, and the supporting part moves with the direction adjusting block, at this time, the supporting part moves from the position directly below the center of gravity of the seesaw body to the position deviating from the center of gravity, and the contact position of the supporting part and the seesaw body is the fulcrum of the seesaw body; at this time, the weight of the two sides of the seesaw body deviates, so that the seesaw body becomes the state of one side swinging down and the other side rising under the action of gravity; when the toy car moves from other track units to the seesaw track unit, the toy car moves along the seesaw body; as the toy car moves from the side swinging down to the side rising of the seesaw body, the side rising of the seesaw body swings down under the gravity of the toy car and contacts with the base, so that the toy car can smoothly pass through and move to the next track unit. When it is needed to change the moving direction of the toy car, the direction adjusting block only needs to be moved from the left side / right side to the right side / left side, so that the seesaw body can smoothly change from the state of rising on the left side / right side to the state of rising on the right side / left side. After the track assembly is completed, the initial direction of the seesaw body of this seesaw track unit can be adjusted at any time, which is convenient and quick to adjust, and the track unit does not need to be disassembled and reassembled.

[0008] Generally, the track connecting pieces arranged at the left and right ends of the base are a protrusion and a groove matched with the protrusion.

[0009] In the preferred embodiment, the front and rear sides of the middle part of the base are respectively provided with mounting grooves, and the front and rear sides of the middle part of the seesaw body are respectively provided with connecting blocks, and the two connecting blocks are respectively arranged in the two mounting grooves and can move in the mounting grooves. Generally, the left and right ends of the base are respectively provided with stop blocks for limiting the swing amplitude of the seesaw body, so that when one side of the seesaw body swings down to the lowest point, the first guide rail on the seesaw body can correspond to the guide rail position at other positions.

[0010] In a further preferred embodiment, the mounting groove is larger than the connecting block; the upper end of the supporting part is provided with a supporting tip which is in contact with the lower surface of the connecting block. Generally, the mounting groove is slightly larger than the connecting block, so that the connecting block can move up and down and left and right in the mounting groove in a small range of motion in addition to rotation. Thus, after the orientation adjusting block is adjusted, the connecting block will slightly descend under the action of gravity and be stopped by the supporting tip against the lower surface of the connecting block. At this time, the contact point between the supporting tip and the connecting block is the fulcrum of the seesaw body, and the seesaw body can swing around this fulcrum. When the seesaw body swings, the connecting block can also slightly move in the mounting groove and will not be limited by the space of the mounting groove to cause the inability to swing.

[0011] In a further preferred embodiment, the lower surface of the connecting block comprises an arc surface and two flat surfaces. The arc surface is in the middle of the lower surface of the connecting block and protrudes downward, and the two flat surfaces are respectively connected to the left and right ends of the arc surface. By using this structure, when the orientation adjusting block is adjusted left and right, the supporting tip will be at the connecting position between the arc surface and the flat surface, and the seesaw body can swing around this position and remain stable and not easily slide left and right.

[0012] In a further preferred embodiment, the front side or the rear side of the orientation adjusting block is provided with an adjusting knob which is exposed to the outside from the side surface of the base; the adjusting knob is provided with a limiting protrusion which corresponds to the vertical position of the supporting tip; the upper surface of the base is provided with a limiting baffle which matches the limiting protrusion and two notches, and the two notches are respectively on the left and right sides of the limiting baffle; the middle position of the arc surface corresponds to the position of the limiting baffle, and the connecting position between the arc surface and the flat surface corresponds to the position of the notches. When adjusting, the orientation adjusting block can be moved by adjusting the knob left and right; when the adjusting knob is in the middle position, the limiting protrusion is blocked by the limiting baffle, and the supporting tip can be below the middle position of the lower surface of the connecting block, so that the seesaw body can freely swing; when the adjusting knob is adjusted to the left or right, the limiting protrusion can be exposed from the notches, so that the supporting tip is at the connecting position between the arc surface and the flat surface. The notches can limit the orientation adjusting block through the limiting protrusion to keep the position of the supporting part stable when the toy car passes through the seesaw body.

[0013] In a further preferred embodiment, the upper surfaces of the mounting groove and the connecting block are both semicircular and protrude upward. In this way, the seesaw body can swing more smoothly.

[0014] In a preferred embodiment, the base has docking portions on its left and right sides, and a second guide rail is provided on the upper surface of the docking portion. The track connector is disposed on the side of the corresponding docking portion. When one side of the seesaw body is lowered to its lowest point, the first guide rail on the seesaw body can correspond to the second guide rail on the docking portion, allowing the toy car to move smoothly from the second guide rail on one docking portion to the first guide rail on the seesaw body, and then from the second guide rail on the other docking portion to the next track unit.

[0015] The beneficial effects of this utility model are that this seesaw track unit can adjust the starting orientation of the seesaw at any time according to the direction of the toy car's movement on the track, making operation convenient and quick. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-5 The seesaw track unit shown includes a base 1, a seesaw body 2, and an orientation adjustment block 3. Track connectors are provided at the left and right ends of the base 1, and a first guide rail 201 is provided on the upper surface of the seesaw body 2. The middle part of the seesaw body 2 is movably connected to the base 1. The orientation adjustment block 3 is movably mounted on the base 1 and is provided with a support part 301, which is in contact with the middle part of the seesaw body 2.

[0023] The above seesaw track unit is connected with other track units through the track connecting pieces when in use. After assembly, the direction adjusting block 3 can be moved towards the moving direction of the toy car as needed, and the support part 301 moves with the direction adjusting block 3. At this time, the support part 301 moves from the position directly below the center of gravity of the seesaw body 2 to a position deviating from the center of gravity, and the contact position of the support part 301 and the seesaw body 2 is the fulcrum of the seesaw body 2. At this time, the weight of the two sides of the seesaw body 2 deviates, so that the seesaw body 2 becomes a state of one side swinging down and the other side rising under the action of gravity. When the toy car moves from other track units to the seesaw track unit, the toy car moves along the seesaw body 2. As the toy car moves from the side swinging down to the side rising of the seesaw body 2, the side rising of the seesaw body 2 swings down under the gravity of the toy car and contacts the base 1, so that the toy car can smoothly pass through and move forward to the next track unit. When it is needed to change the moving direction of the toy car, the direction adjusting block 3 is only needed to be moved from the left side / right side to the right side / left side, so that the seesaw body 2 can smoothly change from the state of rising on the left side / right side to the state of rising on the right side / left side. The seesaw track unit can adjust the initial direction of the seesaw body 2 at any time after the track is assembled, which is convenient and quick, and does not need to be disassembled and reassembled.

[0024] The track connecting pieces arranged at the left and right ends of the base 1 are a protrusion 4 and a groove 5 matched with the protrusion 4.

[0025] The front and rear sides of the middle part of the base 1 are respectively provided with mounting grooves 101, and the front and rear sides of the middle part of the seesaw body 2 are respectively provided with connecting blocks 202. The two connecting blocks 202 are respectively arranged in the two mounting grooves 101 and can move in the mounting grooves 101. The left and right ends of the base 1 are respectively provided with limit blocks 102 for limiting the swing amplitude of the seesaw body 2, so that when one side of the seesaw body 2 swings down to the lowest point, the first guide rail 201 on the seesaw body 2 can correspond to the guide rail at other positions.

[0026] The size of the mounting groove 101 is larger than that of the connecting block 202; the upper end of the supporting part 301 is provided with a supporting tip 3011 which is in contact with the lower surface of the connecting block 202. The size of the mounting groove 101 is slightly larger than that of the connecting block 202, so that the connecting block 202 can move slightly in the up-down and left-right directions in the mounting groove 101 in addition to rotation, and thus after the adjustment of the orientation adjustment block 3 is completed, the connecting block 202 will slightly descend under the action of gravity and be stopped by the supporting tip 3011 against the lower surface of the connecting block 202, at this time the contact point of the supporting tip 3011 with the connecting block 202 is the fulcrum of the seesaw body 2, the seesaw body 2 can swing around this fulcrum, and the connecting block 202 can also slightly move in the mounting groove 101 when swinging, and will not be limited by the space of the mounting groove 101 to cause the inability to swing.

[0027] The lower surface of the connecting block 202 comprises an arc surface 2021 and two flat surfaces 2022, the arc surface 2021 is located at the middle position of the lower surface of the connecting block 202 and protrudes downward, and the two flat surfaces 2022 are respectively connected with the left and right ends of the arc surface 2021. By adopting this structure, when the left-right orientation adjustment block 3 is adjusted, the supporting tip 3011 will be located at the connecting position of the arc surface 2021 and the flat surface 2022, the seesaw body 2 can swing around this position and can be kept stable and is not easy to slide left and right.

[0028] The front side or the rear side of the orientation adjustment block 3 is provided with an adjustment knob 302 which is exposed to the outside from the side surface of the base 1; the adjustment knob 302 is provided with a limiting protrusion 3021 which corresponds to the vertical position of the supporting tip 3011; the upper surface of the base 1 is provided with a limiting baffle 103 and two notches 104 which match the limiting protrusion 3021 and are respectively located at the left and right sides of the limiting baffle 103; the middle position of the arc surface 2021 corresponds to the position of the limiting baffle 103, and the connecting position between the arc surface 2021 and the flat surface 2022 corresponds to the position of the notch 104. When adjusting, the left-right adjustment of the adjustment knob 302 can drive the movement of the orientation adjustment block 3; when the adjustment knob 302 is located at the middle position, the limiting protrusion 3021 is stopped by the limiting baffle 103, and the supporting tip 3011 can be located below the middle position of the lower surface of the connecting block 202, at this time the seesaw body 2 can freely swing; when the adjustment knob 302 is adjusted to the two sides, the limiting protrusion 3021 can be exposed from the notch 104, at this time the supporting tip 3011 is located at the connecting position of the arc surface 2021 and the flat surface 2022, the notch 104 can limit the orientation adjustment block 3 through the limiting protrusion 3021, so as to avoid the displacement of the orientation adjustment block 3 when the toy car passes through the seesaw body 2, and keep the position of the supporting part 301 stable.

[0029] The upper surface of the mounting groove 101 and the connecting block 202 are both semicircular and protrude upward. In this way, the seesaw body 2 can swing more smoothly.

[0030] The left and right sides of the base 1 are provided with docking portions 105, and the upper surface of each docking portion 105 is provided with a second guide rail 1051. A track connecting piece is arranged on the side surface corresponding to the docking portion 105. When one side of the seesaw body 2 is lowered to the lowest position, the first guide rail 201 on the seesaw body 2 can correspond to the second guide rail 1051 on the docking portion 105, and the toy car can be moved from the second guide rail 1051 on one side of the docking portion 105 to the first guide rail 201 on the seesaw body 2, and then moved from the second guide rail 1051 on the other side of the docking portion 105 to the next track unit.
