[0038] Embodiment 1

[0039] Referring to Figure 1 - Figure 2 , a schematic diagram of the overall structure of a construction progress display device is provided. A construction progress display device includes a construction component 100, which includes a construction member 101 and a connecting member 102 slidably disposed on one side of the construction member 101, and the other end of the connecting member 102 is connected to a dust cleaning device;

[0040] An installation component 200, which includes a mounting member 201 disposed in the construction member 101, a locking member 202 disposed on one side of the mounting member 201, a limiting member 203 disposed on one side of the mounting member 201, an unlocking member 204 disposed on one side of the mounting member 201, and a reset member 205 disposed in the construction member 101. The mounting member 201 is used to perform telescopic adjustment on the height of the adjustment column 201c, so as to match the height of the insulator during the dust cleaning process. The locking member 202 is used to lock and fix it after the adjustment is completed, reducing the possibility of unstable retraction of the adjustment column 201c during the dust cleaning process. The unlocking member 204 is used to unlock and callback the adjustment column 201c when a callback is required;

[0041] The mounting member 201 includes an adjustment cylinder 201a slidably disposed on one side of the construction member 101 and an adjustment column 201c disposed on one side of the adjustment cylinder 201a. The connecting member 102 includes a connecting rod 102a disposed on one side of the adjustment column 201c.

[0042] Specifically, the structural member 101 includes a mounting table 101a, a support column 101b disposed on one side of the mounting table 101a, a display board 101c slidably disposed on one side of the mounting table 101a, a fixed sleeve 101d disposed on one side of the mounting table 101a, and a fixing plate 101e disposed outside the fixed sleeve 101d;

[0043] The connecting member 102 includes a connecting rod 102a slidably disposed on one side of the fixed sleeve 101d and a plug 102b disposed on one side of the connecting rod 102a. A slot is formed in the side wall of the display board 101c. The plug 102b is inserted into the slot and slidably disposed therein. During installation, the plug 102b is inserted into the slot for quick fixing and installation.

[0044] Operation process: During installation, after placing the display board 101c to be installed on the upper side of the mounting table 101a, the connecting rod 102a is driven to slide by the installation component, so as to drive the plug 102b to be inserted into the slot on the side wall of the display board 101c, thereby realizing the quick fixing and installation of the display board 101c.

[0045] Embodiment 2

[0046] Refer to Figure 2 - Figure 6 This embodiment is different from the first embodiment in that the mounting member 201 includes an adjusting cylinder 201a slidably disposed on one side of the fixed sleeve 101d, a mounting box 201b disposed on one side of the adjusting cylinder 201a, and an adjusting column 201c disposed on one side of the mounting box 201b. The adjusting column 201c is slidably connected to the side wall of the adjusting cylinder 201a. The adjusting column 201c slides within the adjusting cylinder 201a. The width of the mounting box 201b is greater than the diameters of the adjusting cylinder 201a and the adjusting column 201c. The other end of the mounting frame 201e is slidably disposed with the adjusting cylinder 201a.

[0047] Specifically, the mounting member 201 further includes a notch 201d formed on one side of the adjusting cylinder 201a and a mounting frame 201e slidably disposed on one side of the mounting box 201b. The mounting frame 201e is slidably disposed within the mounting box 201b.

[0048] Preferably, the locking member 202 includes a channel 202a formed on one side of the fixed sleeve 101d, a limiting rod 202b disposed on one side of the channel 202a, a locking block 202c slidably disposed outside the limiting rod 202b, and a return spring 202d sleeved outside the limiting rod 202b. The locking member 202 further includes a wedge block 202e disposed on one side of the mounting frame 201e. The inclined surface of the wedge block 202e matches the inclined surface of the locking block 202c. In the initial state, the wedge block 202e is in contact with the inclined surface of the locking block 202c. During the sliding insertion process, the wedge block 202e presses the locking block 202c to slide it inward, and the locking block 202c is inserted into the groove of the wedge block 202e, so as to realize the length sliding adjustment process of the connecting rod 102a, and is used to drive the insertion block 102b to insert into the slot of the display board 101c. When the insertion stops, the vertical surface of the wedge block 202e is in contact with the vertical surface of the locking block 202c, and the mounting frame 201e is locked and fixed, so as to lock and fix the adjusting cylinder 201a and the adjusting column 201c, thereby realizing the fixation of the adjusting column 201c and the connecting rod 102a, and then starting to clean the ash.

[0049] Further, the limiting member 203 includes a mounting groove 203a formed on one side of the mounting frame 201e, a limiting block 203b slidably disposed in the mounting groove 203a, a compression spring 203c disposed in the mounting groove 203a, and a limiting groove 203d formed on one side of the fixed sleeve 101d. The limiting block 203b extends into the limiting groove 203d and is slidably disposed therein. The two ends of the compression spring 203c are respectively connected to the side wall of the mounting portion and the side wall of the limiting block 203b. When the sliding mounting frame 201e slides to the end position, at this time the limiting block 203b slides to one side of the limiting groove 203d, and the limiting block 203b extends into the limiting groove 203d under the influence of the resilience of the compression spring 203c, so as to perform a fixed limiting process on the mounting frame 201e. At this time, the adjusting column 201c slides and extends to the end position and cannot move, which is used to limit the adjusting column 201c and reduce the possibility of its falling off.

[0050] The rest of the structure is the same as that of the embodiment.

[0051] Operation process: During the installation process, press the adjusting cylinder 201a. The adjusting cylinder 201a drives the installation frame 201e and the adjusting column 201c to slide within the fixed sleeve 101d. During the sliding process, it drives the installation block 102b to insert into the slot of the display board 101c for quick fixed installation. When the installation frame 201e slides inside the fixed sleeve 101d, the wedge block 202e contacts the inclined surface of the locking block 202c. During the sliding insertion process, the wedge block 202e squeezes the locking block 202c to slide it inward, and the locking block 202c inserts into the groove of the wedge block 202e, enabling it to adjust the length of the connecting rod 102a, thereby driving the insertion block 102b to slide and insert into the slot on the side wall of the display board 101c. When the insertion stops, the vertical surface of the wedge block 202e contacts the vertical surface of the locking block 202c to lock and fix the installation frame 201e, thereby locking and fixing the adjusting cylinder 201a and the adjusting column 201c, and thus fixing the adjusting column 201c and the connecting rod 102a to complete the fixed installation of the display board 101c.

[0052] When the sliding installation frame 201e slides to the end position, at this time, the limit block 203b slides to one side of the limit groove 203d. Affected by the resilience of the compression spring 203c, the limit block 203b extends into the limit groove 203d to perform fixed limit processing on the installation frame 201e. At this time, the adjusting column 201c slides and extends to the end position and cannot move, which is used to limit the adjusting column 201c and improve the installation stability of the display board 101c.

[0053] Embodiment 3

[0054] Refer to Figure 3 - Figure 9 In this embodiment, which is different from the above embodiments, the unlocking member 204 includes a pressing column 204e slidably disposed on one side of the adjusting cylinder 201a, an extrusion block 204f disposed on one side of the pressing column 204e, an inclined portion 204g disposed on one side of the extrusion block 204f, and a through groove 204h opened on one side of the installation frame 201e. The extrusion block 204f extends into the through groove 204h and is slidably disposed therewith. The width of one end of the extrusion block 204f is higher than that of the other end, and the side wall of the extrusion block 204f is provided with an inclined surface portion. In the initial state, the narrower side of the extrusion block 204f extends into the through groove 204h of the installation frame 201e. When pressing the extrusion column 204e, the extrusion column 204e slides to drive the extrusion block 204f to slide inward. During the sliding process, the inclined surface of the extrusion block 204f will contact the side wall of the through groove 204h. Since one end of the sliding frame is slidably disposed with the installation disk and the other end is slidably disposed with the adjusting frame, when the extrusion block 204f slides inward, it will squeeze the installation frame 201e to drive the installation frame 201e to slide to the side away from the locking block 202c.

[0055] Preferably, the unlocking member 204 further includes a slider 204a disposed on one side of the mounting frame 201e and a sliding groove 204i formed on one side of the mounting box 201b. By providing the slider 204a and the sliding groove 204i, the mounting block can be limited during the sliding process on the side wall of the mounting disc. When the mounting frame 201e slides, it will drive the wedge block 202e to separate from the locking block 202c, thereby releasing the locked limit on the mounting frame 201e and enabling it to perform retraction adjustment.

[0056] Specifically, the unlocking member 204 includes a vertical plate 204b disposed on one side of the mounting box 201b, a side plate 204c disposed on one side of the mounting frame 201e, and a first spring 204d disposed on one side of the vertical plate 204b. The slider 204a extends into the sliding groove 204i and is slidably disposed therein. The two ends of the first spring 204d are respectively connected to the side wall of the vertical plate 204b and the side plate 204c. The first spring 204d is used to drive the mounting frame 201e to reset. At the same time, the elastic coefficient of the first spring 204d is greater than that of the reset spring 202d, so that the wedge block 202e can stably squeeze the locking block 202c during the sliding process and drive it to slide inward.

[0057] Furthermore, the reset member 205 includes a second spring 205a sleeved outside the adjusting column 201c and a third spring 205b disposed inside the mounting frame 201e. The two ends of the second spring 205a are respectively connected to the side wall of the mounting box 201b and the side wall of the fixing plate 101e. The two ends of the third spring 205b are respectively connected to the inner side wall of the mounting frame 201e and the side wall of the extrusion block 204f. The second spring 205a is used to drive the mounting disc and the adjusting cylinder 201a to reset, and the third spring 205b is used to reset the extrusion block 204f.

[0058] The remaining structures are the same as those in the embodiment.

[0059] Operation process: When the display board 101c needs to be quickly disassembled, press the extrusion column 204e. The extrusion column 204e slides to drive the extrusion block 204f to slide inward and extrude. During the sliding process, the inclined surface of the extrusion block 204f will contact the side wall of the through groove 204h. Since one end of the sliding frame is slidably arranged with the mounting plate and the other end is slidably arranged with the adjustment frame, the extrusion block 204f will extrude the mounting frame 201e during the inward sliding process, driving the mounting frame 201e to slide away from the locking block 202c, so that the wedge block 202e is separated from the locking block 202c, and the limiting block 203b can also slide out of the limiting groove 203d, thus releasing the locking limit on the mounting frame 201e and enabling it to be retracted and adjusted. At this time, the mounting plate and the adjustment cylinder 201a are reset and retracted by the restoring force of the second spring 205a, and the third spring 205b is used to reset the extrusion block 204f, and the equipment is reset and retracted for the next fixed installation.
