The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0017] The first embodiment of this application is:

[0018] See also Figures 1 - 3 , Figure 1 This is a schematic diagram of the overall structure of the portable conference table and chair placement auxiliary device of the utility model. Figure 2 This is a structural diagram of the first shaft 102, the shaft sleeve 103, the second shaft 104 and the fixing frame 105 of the present invention. Figure 3 It is a structural schematic diagram of the limiting component of the utility model.

[0019] The portable conference table and chair placement assisting device of the present invention includes a protective housing 101, a first shaft 102, a shaft sleeve 103, a second shaft 104, a fixing frame 105, an infrared level body 106, a first clamping plate 107, a second clamping plate 108, an adjustment screw 109, an adjustment knob 110, a lifting column 111, a triangular base 112, a locking screw 113, and a baffle 114. It solves the problem of the current alignment method of pulling a wire, which is relatively cumbersome, inconvenient, and inaccurate. It is understandable that the above solution can also be used to improve convenience.

[0020] In this embodiment, the protective shell 101 is a rectangular body with an internal cavity and an open side. The projection assembly solves the problem that the current alignment is performed by pulling wires, which is troublesome, inconvenient and inaccurate.

[0021] Among them, the first shaft rod 102 is fixedly connected to the protective shell 101 and is located inside the protective shell 101. The shaft sleeve 103 is sleeved outside the first shaft rod 102 and is rotatably connected to the first shaft rod 102. The second shaft rod 104 penetrates through the shaft sleeve 103 and is fixedly connected to the shaft sleeve 103. The fixing bracket 105 is rotatably installed on the second shaft rod 104. The infrared level body 106 is fixedly connected to the fixing bracket 105 and is located on the side of the fixing bracket 105 away from the second shaft rod 104. The limiting member limits the infrared level body 106. The lifting member is installed on the protective shell 101. The first shaft rod 102 is horizontally installed transversely at the inner top of the protective shell 101 and is connected to the inner walls on both sides of the protective shell 101 at both ends, so as to be fixed. The shaft sleeve 103 is sleeved on the first shaft rod 102 through a bearing and can rotate freely on the first shaft rod 102. The second shaft rod 104 penetrates through the shaft sleeve 103 and is rotatably connected to the shaft sleeve 103 through a bearing. The fixing bracket 105 is U-shaped and is rotatably connected to the second shaft rod 104 through a bearing. The infrared level body 106 is fixed to the bottom of the fixing bracket 105 by bolts. Through the first shaft rod 102, the shaft sleeve 103, the second shaft rod 104 and the fixing bracket 105, under the action of gravity, the infrared level body 106 can be automatically leveled. When the infrared level body 106 tilts in any direction, the first shaft rod 102, the shaft sleeve 103, the second shaft rod 104 and the fixing bracket 105 cooperate to ensure that the infrared level body 106 is completely horizontal. The infrared level body 106 is a prior art. It uses a laser or infrared light source and can emit a vertical light plane through a special optical system. It has high precision and stability within a certain distance and can be used in various application scenarios such as measurement, positioning and calibration. The limiting member is used to limit the infrared level body 106 to prevent the infrared level body 106 from shaking randomly when not in use. The lifting member is used to adjust the height of the protective shell 101, so as to meet the adjustment of the position height of the infrared level body 106. By projecting the light emitted by the infrared level body 106 onto the ground, the staff can arrange tables and chairs along the light. The accuracy is very high and the operation is convenient, solving the problem that it is more troublesome, inconvenient and inaccurate to align by the current method of pulling a wire.

[0022] Secondly, the first clamping plate 107 is slidably connected to the protective shell 101 and is located on one side of the protective shell 101 close to the infrared level body 106; the second clamping plate 108 is slidably connected to the protective shell 101 and is located on one side of the protective shell 101 close to the infrared level body 106; the control member drives the first clamping plate 107 and the second clamping plate 108 to move simultaneously. The first clamping plate 107 and the second clamping plate 108 are respectively located on both sides of the infrared level body 106. A sliding groove is provided at the inner bottom of the protective shell 101. The first clamping plate 107 and the second clamping plate 108 are slidably connected to the protective shell 101 through the sliding groove. The control member is used to drive the first clamping plate 107 and the second clamping plate 108 to approach or move away from each other simultaneously. By the simultaneous approach of the first clamping plate 107 and the second clamping plate 108, the infrared level body 106 is clamped and fixed, thereby realizing the limitation of the infrared level body 106.

[0023] Meanwhile, the adjusting screw 109 is rotatably connected to the protective shell 101 and is threadedly connected to the first clamping plate 107 and the second clamping plate 108 respectively; the adjusting knob 110 is fixedly installed at the end of the adjusting screw 109. The adjusting screw 109 extends into the protective shell 101 and is connected to the protective shell 101 through a bearing. The adjusting screw 109 is a bidirectional screw, and the thread directions at both ends are opposite. Both the first clamping plate 107 and the second clamping plate 108 have threaded through holes. The first clamping plate 107 and the second clamping plate 108 are sleeved on both ends of the adjusting screw 109 through the threaded through holes. The adjusting knob 110 facilitates the rotation of the adjusting screw 109. By turning the adjusting knob 110, the first clamping plate 107 and the second clamping plate 108 can be driven to approach or move away from each other.

[0024] In addition, the lifting column 111 is fixedly connected to the protective shell 101 and is located at the bottom of the protective shell 101; the triangular bottom frame 112 is slidably connected to the lifting column 111 and is located at one end of the lifting column 111 away from the protective shell 101; the locking screw 113 extends into the triangular bottom frame 112 and is threadedly connected to the triangular bottom frame 112. The lifting column 111 is vertically arranged at the bottom of the protective shell 101. The triangular bottom frame 112 is composed of a barrel sleeve and three brackets. The lifting column 111 extends into the barrel sleeve and is slidably connected to the barrel sleeve. The three brackets can be extended and retracted. By tightening the locking screw 113, the end of the locking screw 113 can be abutted against the lifting column 111 to limit the lifting column 111. Through the lifting column 111, the triangular bottom frame 112 and the locking screw 113, the lifting adjustment of the protective shell 101 can be realized.

[0025] Finally, the baffle 114 is slidably connected to the protective shell 101 and is located on one side of the protective shell 101. The baffle 114 is arranged on the open side of the protective shell 101. By sliding the baffle 114, the open mouth of the protective shell 101 can be opened and closed. Through the baffle 114, the infrared level body 106 can be protected when not in use.

[0026] In this embodiment, when in use, place the whole device at an appropriate position, turn the locking screw 113 to vertically move the protective shell 101, adjust the infrared level body 106 to an appropriate position, and then tighten the locking screw 113. Then, open the baffle 114, loosen the adjustment knob 110 to make the first clamping plate 107 and the second clamping plate 108 move away from each other, so that the infrared level body 106 is in an unlocked state. After that, turn on the infrared level body 106. The infrared level body 106 emits a vertical light plane, which irradiates out from the open mouth of the protective shell 101 and projects a straight light on the ground. The staff can arrange the tables and chairs along the light, with high precision and convenient operation, solving the problems that the current alignment method by pulling a wire is relatively troublesome, inconvenient and inaccurate.
