[0029] Embodiment

[0030] Such as Figure 1 And Figure 2As shown in the figure, a gate for a positioning pen has a gate body 1 and a rotating seat 2, and also has a rotating mechanism 3 and a locking mechanism 4. The rotating mechanism 3 has a rotating shaft 31 and a rotating disk 32. The rotating disk 32 is rotatably arranged on the rotating shaft 31. The rotating shaft 31 is arranged on the rotating seat 2, and the gate body 1 is linked with the rotating disk 32. The locking mechanism 4 has a locking pin 41 and a locking hole 42. The locking pin 41 is movably arranged above the rotating disk 32, and the locking hole 42 is arranged on the edge of the rotating disk 32.

[0031] The gate body 1 is linked with the rotating disk 32. The rotating disk 32 rotates around the rotating shaft 31, driving the gate body 1 to rotate on the rotating seat 2. By adjusting the angle between the gate body 1 and the rotating seat 2, three states of the gate body 1 opening outwards, closing, and opening inwards can be achieved in sequence. The locking pin 41 is movably arranged above the rotating disk 32. When the locking hole 42 rotates to directly below the locking pin 41, the locking pin 41 is inserted into the locking hole 42, and the position of the gate body 1 is locked by limiting the angle of the rotating disk 32.

[0032] The locking hole 42 is successively provided with a first locking hole 421, a second locking hole 422, and a third locking hole 423. The first locking hole 421, the second locking hole 422, and the third locking hole 423 are successively distributed along the circumferential direction of the rotating disk 32. The first locking hole 421 and the third locking hole 423 are oppositely arranged. The second locking hole 422 is oppositely arranged with the gate body 1. The first locking hole 421 is arranged outside the gate body 1, and the third locking hole 423 is arranged inside the gate body 1.

[0033] When the locking pin 41 is inserted into the first locking hole 421, the gate body 1 opens outwards. When the locking pin 41 is inserted into the second locking hole 422, the gate body 1 closes. When the locking pin 41 is inserted into the third locking hole 423, the gate body 1 opens inwards.

[0034] In this embodiment, the first locking hole 421, the second locking hole 422, and the third locking hole 423 are all adapted to the shape of the locking pin 41. The locking pin 41 is cylindrical, and the cross-sections of the first locking hole 421, the second locking hole 422, and the third locking hole 423 are all U-shaped, which is convenient for production and processing.

[0035] A limiting plate 321 is arranged on the upper end surface of the rotating disk 32. The limiting plate 321 is arranged between the first locking hole 421 and the second locking hole 422 and is close to the second locking hole 422. The locking mechanism 4 also has a limiting mechanism 43 for limiting the position of the locking pin 41. In this embodiment, the limiting plate 321 is made of angle iron and is fixed to the upper end surface of the rotating disk 32 by welding, which can ensure the strength of the limiting plate 32. During installation, as long as the lower end surface of the limiting plate 321 is smooth, it can be ensured that the limiting plate 321 is vertically arranged on the rotating disk 32, which is convenient for installation.

[0036] The limiting mechanism 43 is used to limit the position of the locking pin 41. By controlling the height of the locking pin 41, it can be ensured that the position of the bottom end of the locking pin 41 is higher than the rotating disk 32 and lower than the limiting plate 321. At this time, when the door body 1 rotates outward until the limiting plate 321 abuts against the locking pin 41, it cannot rotate outward any further, but the door body 1 can be opened inward, realizing the automatic switching between the two states of the door body 1 opening inward and the door body 1 closing.

[0037] The limiting mechanism 43 is provided with a limiting seat 431. The limiting seat 431 is provided with a vertically arranged mounting hole 4311, and the locking pin 41 is movably arranged in the mounting hole 4311; a positioning block 411 is arranged on the side surface of the locking pin 41. The positioning block 411 is provided with a first positioning portion 4111 and a second positioning portion 4112. The second positioning portion 4112 is arranged outside the first positioning portion 4111, and the position of the second positioning portion 4112 is higher than the position of the first positioning portion 4111; the upper end surface of the limiting seat 431 is provided with a first limiting groove 4312 and a second limiting groove 4313. Both the first limiting groove 4312 and the second limiting groove 4313 are arranged on the side surface of the mounting hole 4311. The shape of the first limiting groove 4312 is adapted to the shape of the first positioning portion 4111, and the shape of the second limiting groove 4313 is the same as the shape of the positioning block 411.

[0038] A positioning hole 43111 is further arranged on one side of the mounting hole 4311, and the shape of the positioning hole 43111 is adapted to the shape of the positioning block 411.

[0039] By rotating the locking pin 41, the angle of the locking pin 41 can be adjusted, and the following working modes can be achieved in sequence, which is convenient for actual operation.

[0040] The locking pin 41 rotates until the first positioning portion 4111 enters the first limiting groove 4312. At this time, the bottom end of the locking pin 41 is higher than the limiting plate 321, and the door body 1 can rotate freely on the rotating seat 2, realizing the free switching among the three states of the door body 1 opening outward, closing, and opening inward.

[0041] The locking pin 41 rotates until the positioning block 411 enters the second limiting groove 4313. The position of the bottom end of the locking pin 41 is higher than the rotating disk 32 and lower than the limiting plate 321. When the door body 1 rotates outward until the limiting plate 321 abuts against the locking pin 41, it cannot rotate outward any further, but the door body 1 can be opened inward, realizing the automatic switching between the two states of the door body 1 opening inward and the door body 1 closing.

[0042] The locking pin 41 rotates until the positioning block 411 enters the positioning hole 43111, and the locking pin 41 drops and is inserted into the locking hole 42, which can make the door body 1 be in one of the three states of opening outward, closing, and opening inward.

[0043] In this embodiment, an operation hole 412 is further provided at the top end of the locking pin 41. By inserting a finger into the operation hole 412, the locking pin 41 can be conveniently controlled, and the operation is convenient.

[0044] A rotation hole 322 is provided on the rotation disk 32, and the rotation shaft 31 penetrates through the rotation hole 322; the rotation hole 322 is provided at the center of the rotation disk 32.

[0045] The limit seat 431 is provided with an upper limit plate 4314 and a lower limit plate 4315. The upper limit plate 4314 is provided directly above the lower limit plate 4315. Both the first limit groove 4312 and the second limit groove 4313 are provided on the upper end surface of the upper limit plate 4314, which can reduce the production cost of the limit seat 431.

[0046] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
