Detailed Description

An electronic message leaving machine is shown in figure 1 and comprises a base 1 horizontally placed on the ground, a display screen main body 5 arranged above the base 1 and a control box 4 fixedly connected below the display screen main body 5, wherein an extension mechanism 2 is arranged between the control box 4 and the base 1.

As shown in fig. 2, the elongation mechanism 2 includes a slide pipe 23 vertically disposed on the lower surface of the control box 4, and the upper end surface of the slide pipe 23 is fixedly connected to the center position of the lower surface of the control box 4; the inner circumferential surface of the sliding pipe 23 is provided with an internal thread, and the sliding pipe 23 is connected with a screw 22 through the internal thread; the lower end of the screw 22 is provided with a driving motor 21, the driving motor 21 is fixedly connected on the upper surface of the base 1, and the output shaft of the driving motor 21 is coaxially and fixedly connected with the screw 22; the lower bottom surface of the control box 4 is provided with a limiting component on each of two sides of the sliding pipe 23, the limiting components comprise limiting rods 24 parallel to the screw rods 22, and the lower end surfaces of the limiting rods 24 are fixedly connected with the upper surface of the base 1; the limiting rod 24 is sleeved with a limiting pipe 25 connected with the limiting rod 24 in a sliding mode, and the upper end face of the limiting pipe 25 is fixedly connected with the lower surface of the control box 4.

When a user needs to adjust the height between the display screen main body 5 and the ground, firstly, the driving motor 21 is controlled to work, the driving motor 21 drives the screw rod 22 to rotate, and due to the mutual limiting action of the limiting rod 24 and the limiting pipe 25, the sliding pipe 23 sleeved on the screw rod 22 moves along the axis direction of the screw rod 22, so that the control box 4 fixedly connected on the sliding pipe 23 and the display screen main body 5 fixedly connected on the control box 4 are driven to move along the direction of the screw rod 22, and further, the adjustment of the height between the display screen main body 5 and the ground is realized. When users with different heights use the electronic message leaving machine, the users can adjust the height of the display screen main body 5 to a comfortable position for use, thereby increasing the convenience of using the electronic message leaving machine.

As shown in fig. 2 and 3, in order to prevent the slip pipe 23 from being separated from the screw 22 due to the over-rotation of the screw 22 when the driving motor 21 is operated, the normal operation of the message leaving machine is affected. The outer peripheral surface of the limiting pipe 25 is provided with a slide way 251 which is mutually communicated with the inner wall of the limiting pipe 25, the slide way 251 is arranged along the length direction of the limiting pipe 25, and the outer peripheral surface of the limiting rod 24 is fixedly connected with a slide block 241 matched with the slide way 251. The arrangement of the sliding block 241 and the sliding way 251 makes the limiting rod 24 slide more conveniently in the limiting pipe 25, on the other hand, when the driving motor 21 drives the extension mechanism 2 to adjust the length, the sliding block 241 also slides in the corresponding sliding way 251, and when the extension mechanism 2 is adjusted to the highest or lowest position, the sliding block 241 can be clamped with the corresponding position of the sliding way 251, so that the continuous sliding of the extension mechanism 2 is limited. The sliding of the sliding block 241 in the sliding channel 251 limits the sliding distance between the limiting tube 25 and the limiting rod 24, so that the moving tube can be prevented from being separated from the screw rod 22, and the stability of the extension mechanism 2 in adjusting the distance between the display screen main body 5 and the base 1 is increased.

As shown in fig. 2 and 4, the outer periphery of the elongation mechanism 2 is further provided with a protection component 3 for covering the elongation mechanism 2, the protection component 3 includes a first sheath 31 and a second sheath 32 which are sleeved with each other, the cross sections of the first sheath 31 and the second sheath 32 are both rectangular, and the inner circumferential surface of the first sheath 31 is equal to the outer circumferential surface of the second sheath 32. The first casing 31 is fixedly connected with the upper surface of the base 1, and the second casing 32 is detachably connected with the outer peripheral surface of the control box 4. The maximum stretching length of the protection member 3 is greater than the maximum stretching length of the elongation mechanism 2, so that the first sheath 31 and the second sheath 32 are always in a state of being nested with each other when the elongation mechanism 2 is stretched to the maximum length.

As shown in fig. 2 and 4, each of the two side walls of the control box 4 has a clamping hole 40 horizontally formed in the central direction of the control box 4, a compression spring 42 and a latch 41 are sequentially disposed in the clamping hole 40 along the depth direction of the clamping hole 40, one end of the compression spring 42 is fixedly connected to the bottom surface of the clamping hole 40, the other end of the compression spring 42 is fixedly connected to the latch 41, so that the latch 41 can slide along the depth direction of the clamping hole 40, and one end of the latch 41 close to the second housing 32 is a hemispherical chamfer. The second jacket 32 is provided with a positioning hole 321 corresponding to the position of the position-locking hole 40 for accommodating the sliding-out of the slider 241, an internal thread is provided in the positioning hole 321, a top-contacting bolt 322 connected with the positioning hole 321 through a thread is provided on the outer circumferential surface of the second jacket 32, and the length of the top-contacting bolt 322 is equal to the depth of the positioning hole 321.

As shown in fig. 2 and 4, when the worker installs and fixes the second casing 32 and the control box 4, the worker firstly sleeves the second casing 32 on the outer circumferential surface of the control box 4, and makes the fixture block 41 be clamped into the corresponding positioning hole 321 under the action of the compression spring 42, because one end of the fixture block 41 close to the second casing 32 is hemispherical, a guiding effect is achieved when the fixture block 41 is clamped into the positioning hole 321, and the difficulty in butting the fixture hole 40 and the positioning hole 321 is simplified. When the staff is dismantling second set shell 32 and control box 4, can touch bolt 322 through the top of screwing for the tip top of top touches bolt 322 touches on fixture block 41, and makes fixture block 41 break away from locating hole 321 through the pressure that touches bolt 322, thereby has realized the breaking away from between second set shell 32 and the control box 4, and then is convenient for maintain extension mechanism 2.

As shown in fig. 1, in order to facilitate the user to adjust the height of the electronic message leaving device, a pair of raising buttons 11 for controlling the driving motor 21 to rotate forward and raising the height of the display main body 5 and a pair of lowering buttons 12 for controlling the driving motor 21 to rotate backward are further provided on the base 1.

The working process is as follows: when the user uses the electronic message leaving machine, the motor 21 can be driven to work through the control button, so that the motor drives the screw rod 22 to rotate, the height of the display screen main body 5 can be adjusted, and the electronic message leaving machine can be suitable for different people to use. When the staff needs to debug and maintain the inside of the electronic message leaving machine, the top contact bolt 322 can be screwed, so that the top contact bolt 322 pushes the fixture block 41 out of the positioning hole 321, and the second casing 32 and the control box 4 can be separated from each other. After the maintenance is completed, the second casing 32 can be sleeved on the outer circumferential surface of the control box 4, and the fixture blocks 41 are clamped into the corresponding positioning holes 321, so that the second casing 32 and the control box 4 are fixed to each other.
