Handheld mobile data wireless collector

Abstract

The invention relates to a handheld mobile data wireless collector which comprises a shell, the lower surface of one end of the shell is fixedly connected with a grab handle, and a scanning head is installed at the end, away from the grab handle, of the shell. A programmable controller electrically connected with the scanning head and a built-in power supply used for supplying power to the programmable controller are further installed in the shell. When the whole device slips from the hand of a user accidentally, the first control button loses the hand pressing effect to disconnect the electric connection between the electromagnet and the built-in power supply, the spring in a compressed state can push the movable iron core and the buffer sleeve to reversely slide to the left side of the scanning head, and meanwhile, the cover plate loses the support of the scanning head; under the pushing action of the torsion spring, the scanning head is reversely turned over to cover the free end of the buffer sleeve and is protected by matching with the buffer pad arranged on the inner side wall of the cover plate, and the problem that the scanning head is directly and rigidly collided with the ground and damaged during falling is avoided as much as possible.

Description

Technical Field

[0001] The invention belongs to the technical field of data collectors, and in particular relates to a handheld mobile data wireless collector. Background Art

[0002] Wireless data collectors can be roughly divided into two parts: the acquisition part, such as PLC, acquisition card, analog-to-digital converter, etc. can be used as the acquisition part. The core part is the wireless transmission part, which has radio, Z IGBEE, 2G, 3G, WIFI and other forms. The most widely used in industry is the 2G transmission form.

[0003] When using a handheld wireless data acquisition device, the user may fail to hold the collector tightly and the collector may slip from the hand. Existing collectors generally do not have the function of protecting the scanning head when it falls. When the collector slips, the scanning head may be damaged due to a hard collision with the ground, seriously affecting the service life of the collector. Summary of the invention

[0004] The purpose of the present invention is to provide a handheld mobile data wireless collector with simple structure and reasonable design in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A handheld mobile data wireless collector comprises a shell having a handle fixedly connected to the lower surface of one end, a scanning head being installed at the end of the shell away from the handle, a programmable controller electrically connected to the scanning head and a built-in power supply for powering the programmable controller being also installed in the shell, a shielding sleeve being fixedly provided on the outer surface of the middle section of the shell, an electromagnet being installed in the shielding sleeve, a first control button for controlling the electrical connection between the electromagnet and the built-in power supply being installed on the handle, two groups of symmetrically arranged sliding sleeves being fixedly connected to the side of the shielding sleeve close to the scanning head, a moving iron core being slidably connected in the sliding sleeve, a guide ring being fixedly provided on the middle section of the moving iron core, a spring being sleeved on the moving iron core on the right side of the guide ring, one end of the spring being fixed to the guide ring, and the other end of the spring being fixed to the inner wall of the sliding sleeve, a buffer sleeve being fixedly connected to the end of the moving iron core located outside the sliding sleeve, the buffer sleeve being sleeved on the shell and being able to slide along the length direction of the shell.

[0007] As a further optimization scheme of the present invention, a display screen electrically connected to the programmable controller is fixedly mounted on the outer wall of the shell above the handle, and a charging interface electrically connected to the built-in power supply is provided at one end of the shell away from the scanning head.

[0008] As a further optimization solution of the present invention, a second control button for controlling the electrical connection between the programmable controller and the built-in power supply is also installed below the side of the handle where the first control button is installed.

[0009] As a further optimization solution of the present invention, the shielding sleeve is made of a graphene material with a three-dimensional honeycomb mesh structure, and a cavity for accommodating the electromagnet is provided inside the shielding sleeve.

[0010] As a further optimization scheme of the present invention, when the spring is in an extended state, the free end of the buffer sleeve is located on the left side of the scanning head, and after the electromagnet is energized, the magnetic attraction force on one end of the moving iron core located in the inner cavity of the sliding sleeve is greater than the elastic force of the spring, and the maximum compression length of the spring is greater than the length of the scanning head protruding from the outside of the shell.

[0011] As a further optimization scheme of the present invention, two groups of symmetrically arranged ear plates are fixedly connected to the outer wall of one end of the buffer sleeve close to the shielding sleeve, and the end of the moving iron core located outside the sliding sleeve is fixed to the buffer sleeve through the corresponding ear plate.

[0012] As a further optimization scheme of the present invention, two symmetrically arranged connecting plates are fixedly connected to the outer side wall of one end of the buffer sleeve away from the shielding sleeve, a rotating shaft is rotatably connected between the two connecting plates, a connecting seat is fixedly sleeved on the middle section of the rotating shaft, a cover plate for sealing the outer end of the buffer sleeve is installed on the connecting seat, and torsion springs are sleeved on the rotating shaft on both sides of the connecting seat, one end of the torsion spring is fixed to the connecting plate, and the other end of the torsion spring is fixed to the connecting seat.

[0013] As a further optimization solution of the present invention, a buffer pad is fixedly connected to the inner wall of the cover plate and is arranged in alignment with the scanning head.

[0014] The beneficial effect of the present invention is that when the entire device accidentally slips out of the user's hand, the first control button loses the hand pressing effect and disconnects the electrical connection between the electromagnet and the built-in power supply. At this time, the compressed spring can push the moving iron core and the buffer sleeve to slide in the opposite direction to the left side of the scanning head. At the same time, the cover loses the support of the scanning head, and under the push of the torsion spring, it flips in the opposite direction and covers the free end of the buffer sleeve, and cooperates with the buffer pad arranged on the inner wall of the cover to protect the scanning head, so as to minimize the problem of the scanning head being damaged by direct hard collision with the ground when falling.

DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example

[0026] like Figure 1 - Figure 8As shown, a handheld mobile data wireless collector comprises a shell 1 with a handle 2 fixedly connected to the lower surface of one end, a scanning head 3 is installed at the end of the shell 1 away from the handle 2, a programmable controller 4 electrically connected to the scanning head 3 and a built-in power supply 6 for powering the programmable controller 4 are also installed in the shell 1, a display screen 5 electrically connected to the programmable controller 4 is fixedly installed on the outer wall of the shell 1 above the handle 2, and a charging interface 7 electrically connected to the built-in power supply 6 is provided at the end of the shell 1 away from the scanning head 3. When in use, the scanning head 3 can be aligned with the image to be collected, and the scanning head 3 can be started for scanning. The scanning head 3 can transmit the scanned information to the programmable controller 4, and transmit the information to the display screen 5 for display after being decoded by the programmable controller 4. The charging interface 7 is provided on the shell 1 for charging the built-in power supply 6, which is convenient for users to use;

[0027] A shielding sleeve 11 is fixedly provided on the outer surface of the middle section of the housing 1, and an electromagnet 12 is installed in the shielding sleeve 11. A first control button 8 for controlling the electromagnet 12 to be electrically connected to the built-in power supply 6 is installed on the handle 2. When the user holds the handle 2 and presses the first control button 8, the electromagnet 12 can be electrically connected to the built-in power supply 6 and energized to generate a magnetic force. When the user releases the first control button 8, the built-in power supply 6 is disconnected from the electromagnet 12, so that the electromagnet 12 is powered off and loses its magnetic force.

[0028] The shielding sleeve 11 is made of a graphene material with a three-dimensional honeycomb mesh structure, and a cavity for accommodating the electromagnet 12 is provided inside the shielding sleeve 11. The cavity is provided inside the shielding sleeve 11 for installing the electromagnet 12. Since the shielding sleeve 11 is made of a graphene material with a three-dimensional honeycomb structure, it can reflect and absorb electromagnetic waves multiple times through its internal structure, thereby shielding the influence of magnetic force on the programmable controller 4 when the electromagnet 12 is energized;

[0029] A second control button 9 for controlling the electrical connection between the programmable controller 4 and the built-in power supply 6 is also installed below one side of the handle 2 where the first control button 8 is installed. The second control button 9 is installed on the handle 2 below the first control button 8, so that the user can press the first control button 8 and the second control button 9 with a finger at the same time. When the user presses the second control button 9, the programmable controller 4 is powered on, and the scanning head 3 can be controlled to perform wireless data collection.

[0030] The shielding sleeve 11 is fixedly connected to one side close to the scanning head 3 with two groups of symmetrically arranged sliding sleeves 13, a moving iron core 14 is slidably connected in the sliding sleeve 13, a guide ring 15 is fixedly provided on the middle section of the moving iron core 14, a spring 16 is sleeved on the moving iron core 14 on the right side of the guide ring 15, one end of the spring 16 is fixed to the guide ring 15, and the other end of the spring 16 is fixed to the inner wall of the sliding sleeve 13, a buffer sleeve 17 is provided on the end of the moving iron core 14 located outside the sliding sleeve 13, the buffer sleeve 17 is sleeved on the shell 1 and can slide along the length direction of the shell 1, two groups of symmetrically arranged ear plates 18 are fixedly connected to the outer wall of the end of the buffer sleeve 17 close to the shielding sleeve 11, the end of the moving iron core 14 located outside the sliding sleeve 13 is fixed to the buffer sleeve 17 through the corresponding ear plate 18, and the buffer sleeve 17 is connected to the end of the moving iron core 14 located on the outer wall of the sliding sleeve 13 through the ear plate 18;

[0031] When the spring 16 is in an extended state, the free end of the buffer sleeve 17 is located on the left side of the scanning head 3. When falling, the free end of the buffer sleeve 17 contacts the ground in front of the scanning head 3, so that the buffer sleeve 17 can squeeze the spring 16 to contract for buffering, thereby protecting the scanning head 3;

[0032] After the electromagnet 12 is energized, the magnetic attraction force on one end of the moving iron core 14 located in the inner cavity of the sliding sleeve 13 is greater than the elastic force of the spring 16, and the maximum compression length of the spring 16 is greater than the length of the scanning head 3 protruding from the outside of the housing 1. When the user presses the first control button 8 and the electromagnet 12 is energized, the electromagnet 12 can attract the moving iron core 14 through the magnetic force to slide along the inner cavity of the sliding sleeve 13 and fit the electromagnet 12. At this time, the guide ring 15 synchronously slides and squeezes the spring 16 to contract, and at the same time, the moving iron core 14 is used to pull the buffer sleeve 17 to slide along the housing 1 toward the shielding sleeve 11, so as to avoid the shielding sleeve 11 blocking and affecting the collection wide angle of the scanning head 3, and facilitate data collection through the scanning head 3;

[0033] Two symmetrically arranged connecting plates 19 are fixedly connected to the outer side wall of the end of the buffer sleeve 17 away from the shielding sleeve 11, and a rotating shaft 20 is rotatably connected between the two connecting plates 19. A connecting seat 21 is fixedly sleeved on the middle section of the rotating shaft 20, and a cover plate 22 for sealing the outer end of the buffer sleeve 17 is installed on the connecting seat 21. A buffer pad 24 arranged in alignment with the scanning head 3 is fixedly connected to the inner side wall of the cover plate 22. Torsion springs 23 are sleeved on the rotating shafts 20 on both sides of the connecting seat 21, and one of the torsion springs 23 is The first end of the torsion spring 23 is fixed to the connecting plate 19, and the other end of the torsion spring 23 is fixed to the connecting seat 21. When the spring 16 is in an extended state, the torsion spring 23 can push the rotating shaft 20 to drive the cover 22 to flip under the action of its own elastic force, thereby sealing the free end of the buffer sleeve 17, and cooperating with the buffer pad 24 installed on the cover 22 to further protect the scanning head 3. When the spring 16 is in a contracted state, due to the relative displacement between the buffer sleeve 17 and the scanning head 3, the scanning head 3 can push open the cover 22 to prevent the cover 22 from blocking.

[0034] It should be noted that, when using this handheld mobile data wireless collector, the user holds the handle 2 to align the scanning head 3 with the image to be collected data, and presses the first control button 8 to energize the electromagnet 12 installed in the shielding sleeve 11. After the electromagnet 12 is energized, it can adsorb the moving iron core 14 and slide along the sliding sleeve 13 toward the electromagnet 12 under the action of the magnetic field force and adsorb on the electromagnet 12. At this time, the spring 16 is squeezed by the guide ring 15 and is in a contracted state, and the movement of the moving iron core 14 can pull the buffer sleeve 17 to slide along the shell 1 toward the shielding sleeve 11, so that the buffer sleeve 17 and the scanning head 3 produce relative displacement, and the scanning head 3 can push open the cover plate 22 to prevent the cover plate 22 from blocking. At the same time, the user presses the second control button 9 to make the programmable control When the controller 4 is powered on, the scanning head 3 can be controlled by the programmable controller 4 to perform data collection. When the entire device accidentally slips out of the user's hand, the first control button 8 loses the pressing effect of the hand and disconnects the electrical connection between the electromagnet 12 and the built-in power supply 6. At this time, the electromagnet 12 loses its magnetic attraction to the moving iron core 14, and the compressed spring 16 can push the moving iron core 14 to slide in the opposite direction, and push the buffer sleeve 17 to slide in the opposite direction to the left side of the scanning head 3. At the same time, the cover plate 22 loses the support of the scanning head 3, and is pushed by the torsion spring 23 to flip over and cover the free end of the buffer sleeve 17, and cooperates with the buffer pad 24 set on the inner wall of the cover plate 22 to protect the scanning head 3, so as to avoid the problem of the scanning head 3 being directly damaged by hard collision with the ground when falling.

[0035] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
