Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a disassembly mechanism for an edge protection frame. Background Art

[0002] The edge protection frame usually consists of a base, a side mounting frame and a fence installed on the top of the base. The base is used to seal the edge openings inside the building (such as elevator entrances, water outlets, etc.). In order to improve the installation efficiency, the side mounting frame is usually snap-connected to the base, which can avoid loosening or tightening the screws and greatly improve the installation efficiency.

[0003] However, in order to ensure the installation tightness between the side mounting frame and the base, an interference fit is usually adopted between the side mounting frame and the base. This leads to the situation that the side mounting frame and the base are too tight during the disassembly process, which reduces the disassembly efficiency. Therefore, it is necessary to develop a tool for quickly disassembling the side mounting frame. Utility Model Content

[0004] The utility model aims to provide an auxiliary disassembly mechanism for an edge protection frame, so as to solve the problem of difficult disassembly of the protection frame proposed in the above-mentioned background technology, and has the characteristics of simple structure and convenient use.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] An auxiliary disassembly mechanism for an edge protection frame comprises a fixed seat, a first sliding seat, a second sliding seat, a driving mechanism, an elastic force storage mechanism and a reset mechanism.

[0007] The fixing seat comprises a connected base and a rectangular main body, and a first sliding groove is formed on the upper part of the main body.

[0008] The length of the first slide is equivalent to that of the fixed seat. The upper half of the first slide is provided with a second slide groove, and the lower half has a first dovetail portion. The first dovetail portion is placed in the first slide groove of the fixed seat to enable the first slide and the fixed seat to be slidably connected.

[0009] The lower half of the second slide seat has a second dovetail portion, and the second dovetail portion is placed in the second slide groove of the first slide seat so that the second slide seat is slidably connected to the first slide seat.

[0010] The driving mechanism includes a motor installed on a fixed seat, a driving gear connected to the motor shaft and a driving rack installed on the edge of the first slide seat. The driving rack has a row of teeth. The rotation of the driving gear can drive the driving rack to move and then make the first slide seat slide along the fixed seat. A contact piece is installed in the middle of the driving rack or above the other side of the first slide seat.

[0011] The driving mechanism also includes a main switch installed on the fixing base, a stop switch installed near the upper part of the side of the fixing base and aStart switch , a motor, a stop switch and Start switch are electrically connected to a main switch. When the motor starts to drive the rack to move the first slide forward and the contact piece touches the stop switch, the motor stops. When the first slide moves backward and the contact piece touches the start switch, the motor restarts.

[0012] The elastic energy storage mechanism includes a positioning block fixedly connected to the end of the first slide, a positioning rod fixedly connected to the end of the second slide, and a energy storage spring sleeved on the positioning rod. The positioning block is provided with a positioning hole. The positioning rod passes through the positioning hole of the positioning block, so that both ends of the energy storage spring respectively abut against the end faces of the positioning block and the second slide. An anti - detachment member is connected to the end of the positioning rod, and the positioning block has a control inclined surface.

[0013] The elastic energy storage mechanism further includes a energy storage rod, an energy storage shaft movably connecting the end of the energy storage rod, and an energy storage column fixedly connecting the energy storage shaft above the end of the fixed seat. The other end of the energy storage rod has an inclined end face, and a energy storage clamping block is fixedly arranged below. A energy storage clamping seat is arranged at the end of the second slide near the positioning rod, and the energy storage clamping block has a return inclined surface.

[0014] The function of the reset mechanism is to slide the second slide backward. During this period, the energy storage clamping seat at the end of the second slide passes through the return inclined surface of the energy storage clamping block below the energy storage rod. At the same time, the energy storage spring pushes the first slide backward. At this time, the driving rack drives the driving gear to reverse, and the energy storage rod returns to its position.

[0015] Optimization scheme: The reset mechanism includes an elastic member, a first reset column on the energy storage rod and a second reset column on the second slide. The elastic member connects the first reset column and the second reset column. When the second slide rushes forward, the elastic member is stretched and stores energy. After the second slide finishes the forward impact, the elastic member pulls the second slide back. The elastic member is a rubber rope or a return spring.

[0016] When in use, the present utility model is fixed beside the protective frame, with the front end facing the protective frame and separated by a certain distance. After the front end of the second slide repeatedly impacts the protective frame until the protective frame is loosened, the present utility model has the characteristics of simple structure and convenient use.

[0019] Figure 3 is a schematic diagram of the second use state of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below with specific embodiments.

[0021] Example 1

[0022] refer to Figure 1 , Figure 2 and Figure 3 , an auxiliary disassembly mechanism for an edge protection frame includes a fixed seat 1, a first slide seat 2, a second slide seat 3, a driving mechanism, an elastic force storage mechanism and a reset mechanism.

[0023] The fixing seat 1 comprises a base 11 and a rectangular body which are connected to each other. A first sliding groove 10 is formed on the upper part of the body, and a fixing hole 110 is formed on the base 11 .

[0024] The length of the first slide 2 is equivalent to that of the fixed seat 1. The upper half of the first slide 2 is provided with a second slide groove 20, and the lower half has a first dovetail portion 21. The first dovetail portion 21 is placed in the first slide groove 10 of the fixed seat 1 to enable the first slide 2 and the fixed seat 1 to be slidably connected.

[0025] The lower half of the second slide 3 has a second dovetail portion 31 , and the second dovetail portion 31 is placed in the second slide groove 20 of the first slide 2 so that the second slide 3 and the first slide 2 are slidably connected.

[0026] The driving mechanism includes a motor 7 installed on a base 11 of the fixed seat 1, a driving gear 6 connected to the motor shaft, and a driving rack 5 installed on the edge of the first slide 2. The driving rack 5 has a row of teeth 51. The rotation of the driving gear 6 can drive the driving rack 5 to move through the row of teeth 51, thereby causing the first slide 2 to slide along the fixed seat 1. A contact piece 52 is installed in the middle of the driving rack 5.

[0027] The driving mechanism also includes a main switch 71 installed on the fixing base 1, a stop switch 73 installed near the upper side of the fixing base 1 and a Start switch 72, motor 7, stop switch 73 and Start switch 72 is electrically connected to the main switch 71. When the motor 7 is started to drive the rack 5 to move forward and the contact piece 52 touches the stop switch 73, the motor 7 stops. When the first slide 2 moves backward and the contact piece 52 touches the start switch 72, the motor 7 restarts.

[0028] The elastic force storage mechanism includes a positioning block 22 fixedly connected to the end of the first slide 2, a positioning rod 33 fixedly connected to the end of the second slide 3 and a force storage spring 23 sleeved on the positioning rod 33. The positioning block 22 has a positioning hole, and the positioning rod 33 passes through the positioning hole of the positioning block 22, so that the two ends of the force storage spring 23 respectively abut against the end surface of the positioning block 22 and the second slide 3. The end of the positioning rod 33 is connected to an anti-slip component 34, and the positioning block 22 has a control inclined surface 220.

[0029] The elastic energy storage mechanism further includes an energy storage rod 4, an energy storage shaft 42 that movably connects the end of the energy storage rod 4, and an energy storage column 41 that fixedly connects the energy storage shaft 42 above the end of the fixed seat 1. The other end of the energy storage rod 4 has an inclined end face 40, and an energy storage latch 43 is fixedly arranged below it. An energy storage seat 32 is arranged at the end of the second sliding seat 3 near the positioning rod 33. The energy storage latch 43 has a return inclined face 430.

[0030] When the motor 7 drives the first sliding seat 2 and the energy storage spring 23 to make the second sliding seat 3 slide forward, first, the energy storage seat 32 abuts against the energy storage latch 43, and the second sliding seat 3 stops moving forward. The first sliding seat 2 continues to move forward to compress the energy storage spring 23 for energy storage. When the positioning block 22 of the first sliding seat 2 contacts the inclined end face 40 of the end of the energy storage rod 4, the control inclined face 220 is slidably connected to the inclined end face 40 of the energy storage rod 4, causing the energy storage rod 4 to swing up until the energy storage latch 43 disengages from the energy storage seat 32. At the same time, when the contact piece 52 touches the stop switch 73, the motor 7 stops. At this time, the second sliding seat 3 quickly moves forward under the drive of the energy storage spring 23, and its front end face extends beyond the fixed seat 1 and impacts forward, and the energy storage spring 23 releases.

[0031] After the second sliding seat 3 finishes the forward impact, the reset mechanism slides the second sliding seat 3 backward. During this period, the energy storage seat 32 at the end of the second sliding seat 3 passes through the return inclined face 430 of the energy storage latch 43 below the energy storage rod 4. At the same time, the energy storage spring 23 pushes the first sliding seat 2 backward. At this time, the driving rack 5 drives the driving gear 6 to reverse, and the energy storage rod 4 returns to its position. When the first sliding seat 2 returns to a position where the contact piece 52 touches the start switch 72, the motor 7 restarts. When it is necessary to stop the operation, press the shutdown button on the main switch 71.

[0032] The reset mechanism of this embodiment includes an elastic member 45, a first reset post 44 on the energy storage rod 4, and a second reset post 35 on the second sliding seat 3. The elastic member 45 connects the first reset post 44 and the second reset post 35. When the second sliding seat 3 rushes forward, the elastic member 45 is stretched for energy storage. After the second sliding seat 3 finishes the forward impact, the elastic member 45 pulls the second sliding seat 3 backward. Here, the elastic member 45 can be a rubber cord or a return spring.

[0033] During use, the present utility model is fixed to the side of the protective frame through the fixing hole 110, with the front end facing the protective frame and separated by a certain distance. After repeatedly impacting the protective frame until the protective frame becomes loose, press the shutdown button on the main switch 71 to shut down the motor 7.
