Description

Technical Field

[0001] The utility model relates to the technical field of safety boxes, in particular to a firm and stable pull-rod type safety box. Background Art

[0002] Today's safety boxes are highly sophisticated and made of high-strength materials, effectively preventing external factors from invading the contents. They offer excellent sealing properties and are resistant to climate change under varying conditions. To facilitate mobility, current safety boxes are often equipped with a pull rod and wheels. Most current pull rods are telescopic (this is prior art), but these can easily become loose when used to pull the box. The pull rods are not secure, making them unstable. Current safety boxes lack a secure pull rod, making them prone to shaking when used to pull the box. Therefore, we propose a robust and stable pull rod-type safety box. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1:

[0018] See also Figure 1-3The utility model provides a technical solution: a firm and stable pull-rod type safety box, comprising a safety box 1, the bottom of the safety box 1 is provided with four sets of moving wheels, the top of the safety box 1 is movably and telescopically connected with a pull rod 7, the top of the pull rod 7 is equipped with a button 10, and a plurality of groups of stable holes 8 are provided on the left and right sides of the inner wall of the pull rod 7. The top of the safety box 1 is provided with a placement groove 6, and a fixing seat 9 is provided at the bottom of the placement groove 6. Two groups of through holes 11 are provided on the top of the fixing seat 9. The pull rod 7 is slidably connected in the through hole 11. A cavity 12 is provided inside the fixing seat 9, and a stable component 13 is provided in the cavity 12.

[0019] See also Figure 3 The stabilizing assembly 13 includes two sets of sliding plates 132 slidably connected in the cavity 12, and the two sets of sliding plates 132 are connected to the opposite side walls with a second spring 133. The tops of the two sets of sliding plates 132 are provided with a pull block 135, and a sliding groove 134 is opened on the top of the fixed seat 9. The two sets of pull blocks 135 are slidably connected in the sliding groove 134. Under the action of the sliding groove 134, the pull block 135 moves more stably. The two sets of sliding plates 132 are away from the side walls and are provided with a stabilizing rod 130. One end of the two sets of stabilizing rods 130 respectively passes through the left and right side walls of the cavity 12 and matches the stabilizing hole 8. The end of the stabilizing rod 130 located in the through opening 11 is inclined. The outer walls of the two sets of stabilizing rods 130 are sleeved with a first spring 131. One end of the two sets of first springs 131 is respectively connected to the two sets of sliding plates 132 away from the side wall, and the other ends of the two sets of first springs 131 are respectively connected to the left and right side walls in the cavity 12.

[0020] Working principle: The staff presses the button 10 to drive the pull rod 7 to extend and retract (this is the existing technology). The pull rod 7 cooperates with the moving wheel to drive the safety box 1 to move. When the pull rod 7 is pulled, the pull rod 7 will squeeze the inclined surface of the stabilizing rod 130, and the stabilizing rod 130 drives the sliding plate 132 to move. The sliding plate 132 stretches the first spring 131, and the sliding plate 132 squeezes the second spring 133. When the stabilizing hole 8 and the stabilizing rod 130 are on the same horizontal plane, the first spring 131 and the second spring 133 cooperate to stabilize the box 1. The fixing rod 130 can be inserted into the stabilizing hole 8, so that the pull rod 7 can be firmly positioned, so that the pull rod 7 will not shake when the safety box 1 is pulled. When the pull rod 7 needs to be extended and retracted again, it is only necessary to pull the pull block 135 to drive the sliding plate 132 to move. The sliding plate 132 squeezes the second spring 133, and the sliding plate 132 stretches the first spring 131. The sliding plate 132 drives the stabilizing rod 130 to move out of the stabilizing hole 8. When the pull rod 7 is extended and retracted again, the stabilizing rod 130 can be inserted into the corresponding stabilizing hole 8 for firm positioning.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
