Technical Field

[0001] The present invention relates to the technical field of floor washer head switches, and specifically to a microswitch triggering mechanism. Background Art

[0002] As is well known, a floor washer is a cleaning machine suitable for cleaning hard floors while sucking up sewage and taking the sewage away from the site. Most of its head parts are pistol grips or T-shaped grips, which are combined with operation buttons and display screens, etc., so as to facilitate personnel to hold and observe the equipment situation when using or moving the equipment. And the control of floor washing mostly uses a mechanical structure transmission, and a trigger-type microswitch is mostly used during control.

[0003] Problems existing in the prior art are: The trigger switch mostly achieves control through electronic control components, and its disassembly and assembly are relatively inconvenient, and it is also difficult to replace after damage, and the cost is relatively high. Its stability and adaptability in various environments need to be improved. The situation of mis-triggering and accelerated aging may also occur in different environments, and its flexibility needs to be improved, and it is difficult to switch between double-handed holding and single-handed holding actions; Based on the above-mentioned situation, we found that it is very difficult for the microswitch triggering mechanism of the prior art to solve the above problems in the floor washer equipment usage environment. Therefore, we propose a microswitch triggering mechanism with convenient disassembly and assembly, long service life, low processing and maintenance costs, and suitable for a variety of scenarios. Summary of the Invention

[0004] (1) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a microswitch triggering mechanism, which has the advantages of convenient disassembly and assembly, long service life, low processing and maintenance costs, and being suitable for a variety of scenarios.

[0005] (2) Technical Solutions The above technical object of the present invention is achieved through the following technical solutions: A microswitch triggering mechanism includes a top cover, a front cabin, a rear cabin and a handle. The front cabin is snap-connected to the front side of the rear cabin, the top cover is snap-connected to the tops of the front cabin and the rear cabin. An integrally formed plug pin is provided at the rear side of the front cabin, and a trigger assembly is inserted outside the plug pin. Fixed grooves and movable grooves are provided on the rear side of the front cabin and the front side of the rear cabin, and the handle is arranged inside the fixed groove; The triggering component includes a limiting member and two handles. A triggering member is slidably connected to the front side of the limiting member. A rotatable pin is integrally formed on the outer side of the triggering member. A microswitch body is fixedly connected to the front side of the limiting member by bolts. One side of each of the two handles close to the rotatable pin is movably connected to the rotatable pin. The rotatable pin and the handle are in clearance fit through an oblong hole. The inner side of the handle is rotatably connected to a latch pin. The rear side of the limiting member is snap-connected to a handle. A return spring is provided at the bottom of the triggering member. A protrusion that contacts the bottom of the return spring is provided on the front side of the limiting member.

[0006] With the above technical solution, by providing a top cover, a front cabin and a rear cabin to form a relatively sealed housing as the nose part and support the internal structure, the provided latch pin is used for installing the triggering component, and the fixing groove and the movable groove are used for the handle and the handle part to extend from the inside of the nose. By providing a handle for a person to stably hold the nose position with both hands, so as to facilitate the movement and support of the entire device. When it is necessary to trigger the microswitch body, both hands can hold the handles and move them closer to the handle. At this time, the handles rotate along the latch pin, and the triggering member connected to the rotatable pin slides downward along the limiting member and contacts the triggering end of the microswitch body to perform a triggering action. When the force applied to the handles is stopped, the return spring rebounds to reset the triggering member and stop the triggering action. Compared with triggering by an electric drive element, it is convenient to disassemble and assemble. Since they are all mechanical structures, the processing and maintenance costs are relatively low, and it is not easily affected by the external environment.

[0007] The present invention is further configured as: the triggering member is composed of an integrally formed arc-shaped block, a bottom short rod and a triggering rod. The return spring is sleeved on the outside of the short rod. The rotatable pins are provided on the front side and the rear side of the arc-shaped block. The triggering rod is provided on the top of the triggering end of the microswitch body.

[0008] With the above technical solution, by providing the short rod, it is used to limit the deformation of the return spring. The provided triggering rod will contact the triggering end on the top of the microswitch body when the arc-shaped block drops.

[0009] The present invention is further configured as: the handle is provided inside the movable groove. The handle is composed of a horizontally held handle and a connecting pipe that are snap-connected. An anti-slip pad is sleeved on the outside of the horizontally held handle.

[0010] With the above technical solution, by arranging the handle inside the movable groove, it has a certain amount of movement space to facilitate the angular deflection. The handle composed of the horizontally held handle and the connecting pipe that are snap-connected, in addition to the anti-slip pad and the horizontally held handle for holding, also supports and connects to the water tank and the housing of the floor washer through the connecting pipe.

[0011] The present invention is further configured such that: an upper hanging through-hole is provided inside the handle, a lower hanging through-hole is provided inside the handle grip, and an auxiliary handle is provided at the rear side of the handle grip.

[0012] With the above technical solution, by providing the upper hanging through-hole and the lower hanging through-hole for connecting the auxiliary handle, the auxiliary handle is used to facilitate a person to hold the device with one hand and control it after installation.

[0013] The present invention is further configured such that: the auxiliary handle includes an upper shear frame and a lower shear frame. A rotating shaft is fixedly connected inside the upper shear frame. The outer side of the rotating shaft is rotatably connected to the lower shear frame. The upper shear frame is movably connected to the handle, and the lower shear frame is movably connected to the handle grip.

[0014] With the above technical solution, by providing the upper shear frame in cooperation with the lower shear frame, after the upper shear frame and the lower shear frame are respectively connected to the handle grip and the handle, hold the holding parts of the upper shear frame and the lower shear frame, and apply force with the hand to make the lower shear frame rotate along the handle. The handle grip connected to the lower shear frame will approach the upper shear frame together with the lower shear frame, so as to achieve the effect of being able to control the two handle grips to approach the handle simultaneously with one hand.

[0015] The present invention is further configured such that: a torsion spring is sleeved on the outer side of the rotating shaft. The two ends of the torsion spring are respectively fixedly connected to the upper shear frame and the lower shear frame. Soft rubber sleeves are fixedly connected to the outer sides of the upper shear frame and the lower shear frame.

[0016] With the above technical solution, by providing the torsion spring, the torsion spring will store energy when the upper shear frame and the lower shear frame rotate relative to the rotating shaft, and when the operator's hand stops triggering, the torsion spring will reset to prompt the handle grip to reset. The provided soft rubber sleeves can prevent the hand from slipping when holding.

[0017] The present invention is further configured such that: fork frames are provided on the front sides of the upper shear frame and the lower shear frame. The inner side of the top fork frame is clamped to the handle, and the inner side of the bottom fork frame is clamped to the handle grip.

[0018] With the above technical solution, by providing the fork frames, they are used to be respectively clamped on the outer sides of the handle and the handle grip to prevent slipping and facilitate applying force to the handle grip.

[0019] The present invention is further configured such that: a contact pad is fixedly connected to the inner side of the fork frame. The contact pad is made of rubber material. Connecting pins are slidably connected to the inner sides of the top of the upper shear frame and the bottom of the lower shear frame. The outer side of the top connecting pin is inserted into the upper hanging through-hole, and the outer side of the bottom connecting pin is inserted into the lower hanging through-hole.

[0020] With the above technical solution, by providing the contact pad, it can prevent squeezing damage to the surfaces of the handle and the handle grip caused by excessive force. When the connecting pins are inserted into the upper hanging through-hole and the lower hanging through-hole, they can lock the positions of the fork frame, the handle, and the handle grip.

[0021] The present invention is further configured such that force - receiving blocks are provided at the top of the top connecting pin and the bottom of the bottom connecting pin. A tension spring is fixedly connected to the side of the force - receiving block close to the fork. The bottom of the top tension spring is fixedly connected to the upper shear frame, and the top of the bottom tension spring is fixedly connected to the lower shear frame.

[0022] Adopting the above - mentioned technical solution, by providing the tension spring, after the connecting pin is inserted into the upper hanging through - hole or the lower hanging through - hole, the connecting pin needs to be pulled out of the fork first. At this time, the snap ring is stretched and stores energy, and rebounds and resets after being inserted into the upper hanging through - hole or the lower hanging through - hole to assist in locking, so that it will not fall off without external force influence.

[0023] The present invention is further configured such that a display and control board is installed inside the top cover, and screw holes are provided at the joints of the top cover, the front cabin, and the rear cabin, and they are assembled by bolts.

[0024] Adopting the above - mentioned technical solution, installing the display and control board inside the top cover at the top of the device can facilitate personnel to observe from the top, and further assembling the top cover, the front cabin, and the rear cabin through screw holes and bolts can effectively prevent the structure from disassembling due to equipment vibration or external force prying.

At this time, the handle rotates along the plug pin, and the trigger piece connected to it through the rotating pin slides down along the limiting piece and contacts the trigger end of the micro - switch body to perform the triggering action. When the force applied to the handle is stopped, the return spring rebounds to reset the trigger piece and stop the triggering action. Compared with triggering by an electric drive element, it is convenient to disassemble and assemble. Since it is all mechanical structure, the processing and maintenance costs are relatively low, and it is not easily affected by the external environment. Brief description of the drawings

A return spring 56 is provided at the bottom of the trigger member 54, and a protrusion in contact with the bottom of the return spring 56 is provided on the front side of the limiting member 51; By setting the top cover 1 and the front cabin 2 to cooperate with the rear cabin 3 to form a relatively sealed housing as the nose part and support the internal structure, the set pin 4 is used for installing the trigger assembly 5, and the fixed slot 7 and the movable slot 8 are used for the handle 6 and the handle part 55 to extend from the inside of the nose. By setting the handle 6 for personnel to firmly hold the nose position with both hands, it is convenient to move and support the entire device. When it is necessary to trigger the microswitch body 53, one can hold the handle 55 with both hands and move it close to the handle 6. At this time, the handle 55 rotates along the pin 4, and the trigger member 54 connected to it through the rotating pin 52 slides downward along the limiting member 51 and contacts the trigger end of the microswitch body 53 to perform the triggering action. When the force applied to the handle 55 is stopped, the return spring 56 rebounds to reset the trigger member 54 to stop the triggering action. Compared with triggering by an electric drive element, it is convenient to disassemble and assemble. Since it is all mechanical structure, the processing and maintenance costs are relatively low, and it is not easily affected by the external environment.

[0030] Among them, the trigger member 54 is composed of an integrally formed arc-shaped block, a short rod at the bottom, and a trigger rod. The return spring 56 is sleeved outside the short rod. The rotating pins 52 are arranged on the front and rear sides of the arc-shaped block, and the trigger rod is arranged on the top of the trigger end of the microswitch body 53. By setting the short rod, it is used to limit the deformation of the return spring 56. The set trigger rod will contact the trigger end on the top of the microswitch body 53 when the arc-shaped block drops. The handle 55 is arranged inside the movable slot 8. The handle 6 is composed of a horizontally held grip and a connecting pipe in a clamped connection. An anti-slip pad is sleeved outside the horizontally held grip. By arranging the handle 55 inside the movable slot 8, it has a certain amount of movement space to facilitate the angular deflection. In addition to the anti-slip pad and the horizontally held grip for the holding function, the handle 6 composed of the horizontally held grip and the connecting pipe in a clamped connection is also supported and connected to the water tank and the housing of the floor washer through the connecting pipe. The display and control board is installed inside the top cover 1. There are screw holes at the joints of the top cover 1, the front cabin 2, and the rear cabin 3, and they are assembled by bolts. Installing the display and control board inside the top cover 1 at the top of the device is convenient for personnel to observe from the top. Further assembling the top cover 1, the front cabin 2, and the rear cabin 3 through the screw holes and bolts can effectively prevent the structure from disassembling due to equipment vibration or external force prying.

[0031] Working principle of this embodiment: First, when assembling the structure, the front cabin 2 is snap-connected to the front side of the rear cabin 3, and the top cover 1 is snap-connected to the tops of the front cabin 2 and the rear cabin 3, and is assembled and fixed through the screw holes and bolts at the connection points.

The return spring 56 sleeved on the short rod at the bottom of the trigger member 54 is compressed. The trigger rod of the trigger member 54 contacts the trigger end of the microswitch body 53 to complete the triggering action. After stopping applying force to the handle 55, the return spring 56 rebounds to reset the trigger member 54 and stop the triggering action. Embodiment 2

[0032] Reference Figures 1-7 Moreover, a microswitch trigger mechanism further includes an auxiliary grip 9. The inner side of the handle 6 is provided with an upper hanging through hole 11, and the inner side of the handle 55 is provided with a lower hanging through hole 10. The rear side of the handle 55 is provided with the auxiliary grip 9. The auxiliary grip 9 includes an upper scissors frame 91 and a lower scissors frame 92. The inner side of the upper scissors frame 91 is fixedly connected with a rotating shaft 93. The outer side of the rotating shaft 93 is rotationally connected with the lower scissors frame 92. The upper scissors frame 91 is movably connected with the handle 6, and the lower scissors frame 92 is movably connected with the handle 55. By providing the upper hanging through hole 11 and the lower hanging through hole 10, they are used to connect the auxiliary grip 9. After the auxiliary grip 9 is installed, it is convenient for personnel to hold and control the device with one hand. The upper scissors frame 91 cooperates with the lower scissors frame 92. After the upper scissors frame 91 and the lower scissors frame 92 are respectively connected to the handle 55 and the handle 6, hold the holding parts of the upper scissors frame 91 and the lower scissors frame 92, and apply force with the hand to make the lower scissors frame 92 rotate along the handle 6. The handle 55 connected to the lower scissors frame 92 will approach the upper scissors frame 91 together with the lower scissors frame 92, so as to achieve the effect of being able to control the two handles 55 to approach the handle 6 simultaneously with one hand.

[0033] Wherein, a torsion spring 12 is sleeved outside the rotating shaft 93. Two ends of the torsion spring 12 are respectively fixedly connected to the upper shear frame 91 and the lower shear frame 92. Soft rubber sleeves are fixedly connected to the outsides of the upper shear frame 91 and the lower shear frame 92. By providing the torsion spring 12, when the upper shear frame 91 and the lower shear frame 92 rotate relative to the rotating shaft 93, the torsion spring 12 will store energy, and when the operator's hand stops triggering, the torsion spring 12 will reset to prompt the handle 55 to reset. The provided soft rubber sleeves can prevent the hand from slipping when holding. Fork frames 13 are provided on the front sides of the upper shear frame 91 and the lower shear frame 92. The inner sides of the top fork frames 13 are clamped to the handle 6, and the inner sides of the bottom fork frames 13 are clamped to the handle 55. By providing the fork frames 13, they are used to be respectively clamped outside the handle 6 and the handle 55 to prevent slipping and facilitate applying force to the handle 55. A contact pad is fixedly connected to the inner side of the fork frame 13. The contact pad is made of rubber material. Connecting pins 14 are slidably connected to the inner sides of the top of the upper shear frame 91 and the bottom of the lower shear frame 92. The outside of the top connecting pin 14 is inserted into the upper hanging through hole 11, and the outside of the bottom connecting pin 14 is inserted into the lower hanging through hole 10. By providing the contact pad, it can prevent excessive force from causing extrusion damage to the surfaces of the handle 6 and the handle 55. When the provided connecting pins 14 are inserted into the upper hanging through hole 11 and the lower hanging through hole 10, the positions of the fork frames 13, the handle 6 and the handle 55 can be locked. Force receiving blocks are provided at the top of the top connecting pin 14 and the bottom of the bottom connecting pin 14. A tension spring 15 is fixedly connected to the side of the force receiving block close to the fork frame 13. The bottom of the top tension spring 15 is fixedly connected to the upper shear frame 91, and the top of the bottom tension spring 15 is fixedly connected to the lower shear frame 92. By providing the tension spring 15, after the connecting pin 14 is inserted into the upper hanging through hole 11 or the lower hanging through hole 10, the connecting pin 14 needs to be first pulled out of the fork frame 13, and at this time the retaining spring is stretched and stores energy, and rebounds and resets after being inserted into the upper hanging through hole 11 or the lower hanging through hole 10 to assist in completing the locking so that it will not fall off without external force influence.

[0034] Working principle of this embodiment: Pull the top connecting pin 14 and the bottom connecting pin 14 to stretch the tension spring 15. Clamp the inner side of the top fork 13 outside the handle 6 and the inner side of the bottom fork 13 outside the handle 55. Then release the connecting pin 14 to let the tension spring 15 rebound, so that the top connecting pin 14 is inserted into the upper hanging through hole 11 of the handle 6 and the bottom connecting pin 14 is inserted into the lower hanging through hole 10 of the handle 55, completing the connection and locking of the auxiliary grip 9 with the handle 6 and the handle 55. Hold the soft rubber sleeves on the outer sides of the upper shear frame 91 and the lower shear frame 92 and apply force to make the lower shear frame 92 rotate relative to the upper shear frame 91 around the rotating shaft 93. At this time, the torsion spring 12 stores energy. The rotation of the lower shear frame 92 drives the connected handle 55 to approach the handle 6. The handle 55 rotates along the plug pin 4, and the trigger member 54 slides downward along the limiting member 51 through the rotating pin 52. The trigger rod of the trigger member 54 contacts the trigger end of the microswitch body 53, realizing the triggering of the microswitch body 53. Release the force applied by the hand to the auxiliary grip 9. The torsion spring 12 releases the stored energy, causing the lower shear frame 92 to reset, and further driving the handle 55 to reset. At the same time, the trigger member 54 also resets under the action of the return spring 56, stopping the triggering of the microswitch.
