Description

Technical Field

[0001] The utility model relates to a control box for an andon device, belonging to the technical field of installation protection. Background Art

[0002] An andon is a device used to control or manage lighting systems. It primarily functions as a switch, dimming, and color adjustment for lamps. It also has an alarm function for use in flammable environments or mines. For safe use, effective protective measures are required.

[0003] When andon equipment is used in special environments such as flammable environments or mines, the control system storage box usually does not have explosion-proof functions and is easily hit, causing damage to internal components. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a control box for an andon device, which solves the problem in the prior art that the outer shell of the control box is difficult to protect the internal components under emergency circumstances in special environments.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: a control box for an andon device, comprising a box body with an andon device installed inside, the box body being made of multiple metal shells; a box door being arranged on the shell for opening and closing; a center rod being arranged at the center of the box body, with both ends passing through the shell of the box body and extending outside the box body, the upper end of the center rod being connected to a center beam, and the lower end being connected to a chassis, and two top plates being symmetrically arranged on the left and right of the center beam; wherein the interior of the center beam is hollow and is provided with a return spring, one end of the return spring being fixed to the inner wall of the center beam, and the other end being fixed to the top plate, the top plate being kept horizontal by the return spring, and when the top plate is impacted, the return spring is compressed, and the top plate rotates toward the box body with the support beam as the axis.

[0006] By adopting the above technical solution, the box body has an explosion-proof function, can withstand external impacts, and protect the components inside the box from damage. When the top of the box body is impacted by an external object, the top plate first rotates around the center beam as the axis, causing the entire box body to move downward along the center rod. The bottom surface of the box body gradually approaches the chassis. Due to the rotation of the top plate, the impacting object slides along the top plate, thus preventing foreign objects from accumulating on top of the box body. When impacted, the box body as a whole descends, and the distance between the raised edge and the upper surface of the box body gradually increases. The greater the impact force, the greater the inclination of the top plate, and the faster the impacting object rolls down.

[0007] The utility model is further configured as follows: a raised edge is provided on the central beam for resisting impact from foreign objects.

[0008] By adopting the above technical solution, when the impacting object is gravel hitting the raised edge, the raised edge can crush the impacting object, so that the overall mass of the impacting object falling on the top plate and the subsequent impact force are reduced, effectively reducing the impact force on the top plate.

[0009] The utility model is further configured as follows: an oblique support rod is hinged on the outer side of the top plate, a slider 1 is hinged on the other end of the oblique support rod, and the slider 1 is slidably arranged on the upper surface of the box body.

[0010] By adopting the above technical solution, when the top plate is impacted, the diagonal support rod pushes slider one to slide. Slider one is then pushed by the diagonal support rod toward the center of the upper surface of the box, thereby pushing the box downward along the center rod. The diagonal support rod acts as a transition, transmitting the impact force on the top plate, thereby preventing direct collision between the box and the top plate, and reducing the impact of vibration on the box.

[0011] The utility model is further configured as follows: a plurality of vertical support rods are hinged on the chassis, a second slide block is hinged on the other end of the vertical support rod, and the second slide block is slidably arranged on the lower surface of the box body.

[0012] By adopting the above technical solution, when the box moves downward along the center rod, the vertical support rod rotates toward the horizontal direction, and the second slider slides toward the outer periphery of the bottom surface of the box. The vertical support rod serves as a supporting transition to lift the box, which can maintain a relatively stable state when the box is raised and lowered, thereby preventing damage to the internal components of the box.

[0013] The utility model is further configured as follows: support rods are provided at the four corners of the lower surface of the box body, corner plates are provided at the bottoms of the support rods, and buffer springs are sleeved on the support rods.

[0014] By adopting the above technical solution, the box is supported by the support rods, so that the bottom of the box is not in direct contact with the ground, which can prevent the bottom of the box from getting damp and affecting the service life of the components inside the box.

[0015] The present invention is further configured as follows: a slide groove 1 is provided on the upper surface of the box body, the slider 1 is slidably engaged in the slide groove 1, and a spring 1 is provided between the slider 1 and the slide groove 1.

[0016] By adopting the above technical solution and setting the spring 1, when the slider 1 moves toward the center of the upper surface of the box, the spring 1 can exert a reverse elastic force on the slider 1, thereby playing a buffering role for the slider.

[0017] The present invention is further configured as follows: a plurality of second slide grooves are provided on the lower surface of the box body, the second slider is slidably engaged in the second slide grooves, and a second spring is provided between the second slider and the second slide grooves.

[0018] By adopting the above technical solution, when the slider 2 slides toward the periphery of the bottom surface of the box, the spring 2 can act as a buffer for the slider 2, preventing the vertical support rod used to push the slider 2 from rotating and tilting instantly.

[0019] The beneficial effect of the utility model is that the rotatable top plate can buffer external impact objects, prevent the box from being directly impacted and causing damage to the components inside the box, thereby improving the stability of the control box.

[0020] By setting the diagonal support rods and vertical support rods as well as slider one and slider two, the entire box can be supported in a suspended manner, so that the box will not be affected by the impact force in the first time. Instead, the force is transmitted through the diagonal support rods, which to a certain extent reduces the vibration generated by the box when it is impacted. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0027] like Figure 1 As shown, a control box for an andon device includes a box body 1, in which an andon device is installed. The box body 1 is composed of multiple metal shells 2; a box door 3 is provided on the shell 2 for opening and closing; a center rod 4 is provided at the center of the box body 1, with both ends passing through the shell 2 of the box body 1 and extending outside the box body 1. The upper end of the center rod 4 is connected to a center beam 5, and the lower end is connected to a chassis 6. Two top plates 7 are symmetrically provided on the center beam 5.

[0028] Among them, the interior of the center beam 5 is hollow and is provided with a return spring 8. One end of the return spring 8 is fixed to the inner wall of the center beam 5, and the other end is fixed to the top plate 7. The top plate 7 is kept horizontal by the return spring 8. When the top plate 7 is impacted, the return spring 8 is compressed, and the top plate 7 rotates toward the box body 1 with the support beam as the axis.

[0029] Specifically, such as Figure 4 As shown, there are two return springs 8. A stopper is fixed in the middle of the inner cavity of the center beam 5. The ends of the two return springs 8 are fixed to the opposite sides of the stopper, and the other ends are fixed to the stopper. When the top plate 7 rotates, the return springs 8 are rotated and compressed by the top plate 7. After the impact object on the top plate 7 slides off, the top plate 7 can rotate back to its initial horizontal state under the action of the return springs 8.

[0030] like Figure 3 As shown, support rods 14 are installed at the four corners of the lower surface of the box 1. Angle plates 15 are installed at the bottom of these support rods 14, and buffer springs 16 are sleeved on these support rods 14. The support rods 14 are connected to the box 1 in a sliding manner. When the box 1 is impacted, it can move along the axis of the support rods 14, and the buffer springs 16 are compressed. The box 1 is primarily fixed to the ground by the angle plates 15 at the bottom of the support rods 14. The contact between the angle plates 15 and the ground prevents the bottom surface of the box 1 from directly contacting the ground, thereby preventing the bottom surface of the box 1 from getting damp, which would affect the service life of the box 1.

[0031] When the box body 1 is impacted from above, the impacting object first strikes the top plate 7, causing the top plate 7 to rotate about the center beam 5, pushing the entire box body 1 downward. The top plate 7 protects the box body 1 from direct impact by external objects, reducing the impact force on the box body 1. When impacted, the top plate 7 tilts at an increasing angle as the impact force increases, allowing any impacting object remaining on the top plate 7 after the impact to quickly slide down along the inclined surface of the top plate 7, preventing the impacting object from remaining on the top plate 7.

[0032] The buffer spring 16 can restore the top plate 7 to its original state after the impact object slides down, so that it can effectively play a buffering role when it is hit next time.

[0033] like Figure 2 As shown, further, a diagonal brace 10 is hingedly connected to the outer side of the top plate 7, and a slider 11 is hingedly connected to the other end of the diagonal brace 10. The slider 11 is slidably disposed on the upper surface of the box body 1. A slide groove 17 is provided on the upper surface of the box body 1, and the slider 11 is slidably engaged in the slide groove 17. A spring 18 is provided between the slider 11 and the slide groove 17.

[0034] When the top plate 7 is impacted, the diagonal support rod 10 pushes the slider 11 to slide in the slide groove 17. Since a spring 18 is provided in the slide groove 17, the spring 18 is continuously compressed when the slider 11 slides. The greater the impact force, the greater the compression amount, and the greater the elastic force applied to the slider 11 in the reverse direction. Therefore, through the reverse elastic force of the spring 18, the box body 1 can obtain a good buffering effect when it is impacted, thereby reducing the impact of the impact vibration on the internal components of the box body 1.

[0035] like Figure 3 As shown, further, the chassis 6 is hinged with a plurality of vertical support rods 12, and the other end of each vertical support rod 12 is hinged with a second slider 13, which is slidably disposed on the lower surface of the box body 1. The lower surface of the box body 1 is provided with a plurality of second chute grooves 19, in which the second slider 13 is slidably engaged, and a second spring 20 is provided between the second slider 13 and the second chute groove 19.

[0036] When the box body 1 is subjected to external impact or vibration, the vertical support rod 12 and the slider 2 13 can effectively disperse and absorb the impact energy, reducing the risk of deformation and damage to the box body 1. The spring 20 acts as a shock-absorbing element and can play a buffering role when the box body 1 is subjected to impact or vibration. This not only improves the durability of the box body 1, but also extends its service life and reduces replacement and maintenance costs. The combined design of the vertical support rod 12 and the slider 2 13 makes the installation and maintenance of the box body 1 easier. When replacement or maintenance is required, the relevant components can be easily disassembled and reinstalled, reducing the difficulty and cost of maintenance.

[0037] Further, such as Figure 4 As shown, the center beam 5 is provided with raised ridges 9 to protect against impacts from external objects. Serving as additional support, these ridges 9 more effectively disperse and absorb external impact energy, reducing the risk of structural damage. When a foreign object strikes the center beam 5, these ridges 9 act as a first line of defense, slowing the impact and dispersing the force, thereby minimizing direct damage to the center beam 5. The shape and distribution of these ridges 9 can be optimized to maximize impact resistance and ensure structural stability in the event of an impact.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art will appreciate that the present invention is not limited to the above embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such modifications and improvements fall within the scope of protection claimed by the present invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
