The control box of the elevator without a machine room is placed in the shaft. The control box is composed of a sheet metal frame structure and bolts. The existing control box often has the problem of heating during use. The usual heat dissipation method is to use a fan, but the fan heat dissipation often causes dust accumulation on the filter, resulting in filter blockage.

[0003] Therefore, it is necessary to provide an elevator shaft control box ventilation structure that can avoid filter clogging. Utility Model Content

[0004] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0005] The utility model is a ventilation structure of an elevator shaft control box, comprising a control box body and a box door movably installed at the center of the front end surface of the control box body through hinges, ventilation frames are fixedly connected below the outer walls of both sides of the control box body, heating wires are hoisted on the inner side of the ventilation frame, adjustment grooves are arranged on one side of the front and rear end surfaces of the ventilation frame, dredging components are arranged on the inner and outer sides of the ventilation frame, and buffer components are arranged between adjacent adjustment grooves;

[0006] The dredging assembly includes a ventilation plate and ventilation holes evenly spaced on the outer wall thereof, connecting rods are installed in the through holes at four corners of one end surface of the ventilation plate, and first springs are sleeved on both sides of the outer wall of the connecting rods;

[0007] The buffer assembly comprises a filter screen and a slide plate fixedly arranged at the center of the front and rear end surfaces thereof, the slide plate is located inside the slide groove, and the slide groove is arranged at the center of the inner side wall of the moving plate.

[0008] Furthermore, an inspection window is provided on one side of the top of the ventilation frame, and a dust shielding grille is provided on the outer side wall of the ventilation frame.

[0009] Furthermore, a motor is installed at the inner edge of the ventilation frame through a hanging frame, and a fan blade is installed on the output shaft of the motor.

[0010] Furthermore, the ventilation plate is located between adjacent first springs, and both ends of the connecting rod are respectively fixed at opposite end face corners of the adjacent first hollow plate and the second hollow plate.

[0011] Furthermore, the inner wall of the first hollow plate is evenly spaced and fixedly connected with first dredging needles, and the outer wall of the second hollow plate is evenly spaced and fixedly connected with second dredging needles.

[0012] Furthermore, the first unclogging needle and the second unclogging needle combination are arranged in one-to-one correspondence with the ventilation holes, and the four corners of the inner wall of the second hollow plate are fixedly connected with extrusion blocks.

[0013] Furthermore, an adjustment block is fixedly connected to the center position of the outer side wall of the movable plate, a limit rod is arranged in the internal through hole of the adjustment block, and second springs are sleeved on both ends of the outer wall of the limit rod.

[0016] The utility model provides a dredging component, which can enable the first hollow plate and the second hollow plate to reciprocate in the horizontal direction under the elastic force of the first springs on both sides. At the same time, the number and arrangement of the first dredging needle and the second dredging needle are combined to correspond to the ventilation holes one by one. When the first dredging needle and the second dredging needle move back and forth to dredge separately, only a part of the ventilation holes can be cleaned to avoid inserting all the needles into the ventilation holes, resulting in all the ventilation holes being blocked and air being unable to enter, thereby affecting the ventilation effect and efficiency. The dust-proof ventilation structure of the above-mentioned integrated control box avoids blockage by dredging the conical ventilation holes through the dredging needles when in use, while the dredging needles in this way are arranged one by one with the conical ventilation holes. During the dredging process, all the dredging needles will be inserted into the conical ventilation holes, resulting in all the ventilation holes being blocked and air being unable to enter, thereby affecting the ventilation effect and efficiency.

[0017] The utility model provides a buffer component, which can play a buffering and protective role for the filter under the elastic force of the second springs on both sides, thereby reducing the force on the filter and increasing the service life of the filter. It solves the problem that the dust-proof and ventilation structure of the integrated control box causes the filter to vibrate through the protrusions when in use and shakes the dust on it off and collects it, while the filter is subjected to impact force for a long time in this way, resulting in serious wear and tear, which will cause damage to the filter and affect the service life of the filter.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] See also Figures 1 to 4 As shown, the utility model is a ventilation structure of an elevator shaft control box, comprising a control box body 1 and a box door 101 movably installed at the center of the front end face thereof through hinges, ventilation frames 102 are fixedly connected to the lower sides of the outer walls of both sides of the control box body 1, heating wires 104 are suspended on the inner side of the ventilation frame 102, and adjustment grooves 1021 are arranged on one side of the inner front and rear end faces of the ventilation frame 102, and a dredging component 2 is arranged on the inner and outer sides of the ventilation frame 102, and a dust collecting box is arranged on one side of the bottom of the ventilation frame 102, which is a prior art, so it is not described in the drawings and the specification, and the heating wire 104 can be used to increase the temperature of the external air to play a drying role;

[0028] The dredging assembly 2 includes a ventilation plate 201 and ventilation holes 202 evenly spaced on its outer wall. Connecting rods 203 are installed in the through holes at the four corners of one end surface of the ventilation plate 201. First springs 204 are sleeved on both sides of the outer wall of the connecting rod 203. Both ends of the ventilation hole 202 are set in a conical shape.

[0029] A maintenance window 1022 is provided on one side of the top of the ventilation frame 102, and a dust shielding grille 1023 is provided on the outer wall of the ventilation frame 102. The maintenance window 1022 is used to facilitate pulling out the internal filter 301 for replacement and cleaning. A motor 103 is installed at the inner edge of the ventilation frame 102 through a hanging frame 1031, and a fan blade 1032 is installed on the output shaft of the motor 103. The operation of the motor 103 drives the fan blade 1032 to rotate, thereby playing a role in suction.

[0030] The ventilation plate 201 is located between adjacent first springs 204, and the two ends of the connecting rod 203 are respectively fixed at the opposite end face corners of the adjacent first hollow plate 205 and the second hollow plate 206. The first hollow plate 205 and the second hollow plate 206 are connected by the connecting rod 203, which plays a role of connecting transmission, so that the two move synchronously;

[0031] The inner wall of the first hollow plate 205 is evenly spaced and fixedly connected with first dredging needles 2051, and the outer wall of the second hollow plate 206 is evenly spaced and fixedly connected with second dredging needles 2061. The first dredging needles 2051 and the second dredging needles 2061 are combined to correspond to the ventilation holes 202 one by one. The first dredging needles 2051 and the second dredging needles 2061 are combined to correspond to the ventilation holes 202 one by one. The four corners of the inner wall of the second hollow plate 206 are fixedly connected with extrusion blocks 2062.

[0032] When the above arrangement is in use, the motor 103 is started, and the output shaft of the motor 103 rotates to drive the fan blades 1032 to rotate, thereby sucking in air from the external environment. When the air enters, it will first undergo a preliminary dust filtration process under the action of the dust shield grille 1023, and then enter through the first hollow plate 205, the ventilation plate 201 and the second hollow plate 206. During the air entry process, a vibration force will be generated on the first hollow plate 205 and the second hollow plate 206, thereby causing the first hollow plate 205 and the second hollow plate 206 to move. Since the first hollow plate 205 and the second hollow plate 206 are located on both sides of the ventilation plate 201 and the first spring 204 is arranged between adjacent ones, the first hollow plate 205 and the second hollow plate 206 can be reciprocated to the left or right under the action of the vibration force and the elastic force of the first spring 204. Movement, and use the first unclogging needle 2051 and the second unclogging needle 2061 on the first hollow plate 205 and the second hollow plate 206 to pass through the ventilation holes 202 on the ventilation plate 201, so as to clean the dust accumulated in the ventilation holes 202 and improve the filtering efficiency and effect, wherein the number and arrangement of the first unclogging needle 2051 and the second unclogging needle 2061 are combined to correspond one to one to the ventilation holes 202, and when the first unclogging needle 2051 and the second unclogging needle 2061 move back and forth to unclog separately, only a part of the ventilation holes 202 can be cleaned to avoid inserting all the needles into the interior of the ventilation holes 202, resulting in all the ventilation holes 202 being blocked and air unable to enter, thereby affecting the ventilation effect and efficiency, and at the same time, when the second hollow plate 206 moves inward, it will push the structural components located on the inside through the extrusion block 2062.

[0033] Among them Figure 3 , 5 As shown, a buffer assembly 3 is arranged between adjacent adjustment grooves 1021, and the buffer assembly 3 includes a filter screen 301 and a slide plate 3011 fixedly arranged at the center of the front and rear end surfaces thereof, the slide plate 3011 is located inside the slide groove 3021, and the slide groove 3021 is arranged at the center of the inner side wall of the movable plate 302, and the slide plate 3011 and the slide groove 3021 are used to facilitate the installation and removal of the filter screen 301, saving time;

[0034] An adjusting block 303 is fixedly connected to the center of the outer wall of the movable plate 302. A limiting rod 304 is arranged in the inner through hole of the adjusting block 303. Second springs 305 are sleeved on both ends of the outer wall of the limiting rod 304. The adjusting block 303 can slide on the limiting rod 304 and squeeze the second springs 305 on both sides.

[0035] The adjustment block 303 is located between adjacent second springs 305, and the two ends of the limit rod 304 are respectively fixed on the inner walls of the two sides of the adjustment groove 1021, and the elastic force of the second spring 305 can play a buffering and protective role on the filter screen 301;

[0036] When the above arrangement is in use, when the filter 301 is squeezed by the outer structural components, since the slide plates 3011 at the front and rear ends of the filter 301 are both located in the slide grooves 3021 on the inner side of the movable plate 302, the movable plate 302 will be driven to move when the filter 301 is subjected to force, and the adjusting block 303 will be driven to slide inward on the outer wall of the limit rod 304 and squeeze the second spring 305 located on the inner side under the action of the movable plate 302. Since the filter 301 is subjected to the external reciprocating force, the filter 301 will be ejected outward and squeeze the second spring 305 located on the outer side under the elastic force of the inner second spring 305 after the squeezing force disappears, so that the filter 301 can be buffered and protected under the elastic force of the inner and outer second springs 305, so that the force on the filter 301 can be reduced and the service life of the filter 301 can be increased. At the same time, the vibration of the filter 301 can shake the dust on it into the dust collecting box at the bottom.
