Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding protection, and in particular to a portable protection device applicable in multiple scenarios. Background Art
[0002] Currently, when welding fences on the ground or at height within a factory, a fire blanket is typically laid at the welding site to prevent sparks from the welding process from scattering and causing fires. When welding is performed on the factory floor, a fire blanket can be quickly and conveniently laid at the welding site to provide protection during the welding process. However, when a fence high up in the factory is rusted and damaged and needs to be repaired by welding, the fire blanket is difficult to lay at the welding site due to its high altitude and the fact that the fence is usually located at an edge at height. Therefore, it can only be laid nearby to provide auxiliary fire protection.
[0003] Based on the position of the latter fire blanket, the protection effect it can provide is poor. If the laying area of the fire blanket is simply increased, the sparks generated during the welding process will splash from top to bottom due to the high-altitude operation near the edge. The sputtering range is large, and the fire blanket area required is also large, which will cause waste of materials. In addition, this form of large-area laying requires multiple workers to operate and cooperate, which is cumbersome to use.
[0004] To this end, we propose a portable protective device for multi-scenario applications to solve the above problems. Utility Model Content
[0005] The purpose of the present utility model is to solve the problems in the prior art and to propose a portable protective device for multi-scenario application. The protective device covers the welding site by setting a protective cage to achieve good protection for high-altitude operations near edges. The shape of the protective cage is variable, which can not only adapt to high-altitude operations in different places, but also can be folded and stored for easy carrying.
[0006] In order to solve the above problems, the present invention provides the following technical solutions:
[0007] A portable protective device for multiple scenarios includes a protective cage for covering a welding site. The protective cage is composed of multiple connecting rods distributed in a spatial pattern and movably connected to each other, so that the shape of the protective cage can be changed. The protective cage has multiple sides, and a fire blanket is detachably mounted on each side. The fire blanket has a movable margin required for changing the shape of the protective cage.
[0008] As a further solution of the present invention: the protective cage is composed of twelve connecting rods distributed in a spatial shape and movably connected to each other, so that the protective cage as a whole is in the shape of a cube, wherein four connecting rods are distributed in a rectangular shape and are hinged to each other to form an upper frame, and the other four connecting rods are distributed in a rectangular shape and are hinged to each other to form a lower frame, and the upper frame and the lower frame are arranged in parallel, and the remaining four connecting rods are arranged along the connecting line between the upper frame and the lower frame and are used to movably hinge the ends of the upper frame and the lower frame.
[0009] As a further solution of the present invention: the protective device further comprises a hook arranged on the protective cage, and a fastener is provided on the hook.
[0010] As a further solution of the present invention: the fastener includes a fixing bolt threadedly arranged on the hook, and one end of the fixing bolt passes through the hook and extends into the inner side of the hook.
[0011] As a further solution of the present invention: the hook is composed of a straight rod portion and a bent rod portion, the fastener is arranged on the bent rod portion, and the straight rod portion is arranged as a telescopic structure.
[0012] As a further solution of the present invention: the hooks are in two groups and both are arranged on the upper connecting rod.
[0013] As a further solution of the present invention: the fire blanket is detachably arranged on the side of the protection cage by means of snap fasteners.
[0014] As a further solution of the present invention: the protective cage is provided with a lock for locking its shape.
[0015] As a further solution of the present invention: the locking element includes a damping hinge, and any two adjacent connecting rods are connected by the damping hinge.
[0016] As a further solution of the present invention: the locking member includes a screw for locking two adjacent connecting rods.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. Through the installation of protective cages and fire blankets, the protective cage can be used to cover the welding site at high altitudes, so that the sparks generated during welding are confined inside the protective cage by the fire blanket on the protective cage, thus avoiding the occurrence of sparks that may cause fire.
[0019] 2. The protective cage is composed of a plurality of connecting rods distributed in a body shape and movably connected to each other, so that the shape of the protective cage can be changed, and thus it can be adapted for use at different locations of edges and high places, making the utility model widely used and easy to promote and use on a large scale;
[0020] 3. Through the setting of the hook, when in use, the hook can be directly hung on the horizontal crossbar of the fence to lock the position of the protective cage;
[0021] 4. Through the setting of the fastener, when the hook is hung on the inclined cross bar, the position of the hook on the inclined cross bar can be locked by the fastener to achieve the position locking of the protective cage. The utility model can achieve the locking of the protective cage at different positions by using the fastener, and the locking effect is good;
[0022] 5. Through the telescopic structure setting of the straight rod part, the protective cage can be adjusted within a certain height range, which can further increase the applicable range of the protective cage. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] 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.
[0030] like Figures 1-4As shown, a portable protective device suitable for multiple scenarios includes a protective cage 1 for covering corresponding welding sites. The protective cage 1 is composed of multiple connecting rods 101 distributed in a body shape and movably connected to each other, allowing the overall shape of the protective cage 1 to be changed. Protective cages 1 of different shapes can be adapted to high-altitude operations at different locations near edges, thus having a wide range of applications. The protective cage 1 has multiple side surfaces, each of which is removably mounted with a fire blanket 2. The fire blanket 2 has the required margin for the shape changes of the protective cage 1. That is, the fire blanket 2 is installed on the side surface in a pleated shape. When the protective cage 1 is subsequently adjusted and deformed, the fire blanket 2 will not interfere with the adjustment operation.
[0031] The detachable connection arrangement of the fire blanket 2 on the protective cage 1 can be configured as a buckle connection or a snap connection, etc. When configured as a buckle connection, it can be achieved by using a snap fastener.
[0032] It should be noted that the number of connecting rods 101 can be selected according to actual needs. This embodiment uses a protective cage 1 composed of twelve connecting rods 101 as an example for description. Specifically, the protective cage 1 is composed of twelve connecting rods 101 distributed in a spatial pattern and movably connected to each other, so that the protective cage 1 as a whole has a cubic shape. Four connecting rods 101 are distributed in a rectangular pattern and hinged to each other to form an upper frame, and another four connecting rods 101 are distributed in a rectangular pattern and hinged to each other to form a lower frame. The upper frame and the lower frame are arranged parallel to each other, and the remaining four connecting rods 101 are arranged along the line connecting the upper frame and the lower frame and are used to movably hinge each end of the upper frame and the lower frame.
[0033] In order to ensure that the protective cage 1 remains stable after being adjusted to the appropriate shape, a lock for locking its shape can be provided on the protective cage 1. After the protective cage 1 is adjusted and deformed to the corresponding shape, the lock can be used to lock two adjacent connecting rods 101, so that the shape of the protective cage 1 remains stable. The lock can then be released to allow the protective cage 1 to be folded and stored. Specifically, the lock can be configured as a damping hinge or a screw. When configured as a damping hinge, any two adjacent connecting rods 101 are connected by the damping hinge, and the protective cage 1 can be maintained in the corresponding adjusted shape through the damping effect of the damping hinge. When configured as a screw, after the shape of the protective cage 1 is adjusted, the two adjacent connecting rods 101 can be threadedly connected by the screw, so that the position of the two adjacent connecting rods 101 remains stable, that is, the shape of the entire protective cage 1 remains stable. Similarly, a screw can be provided in addition to the damping hinge to achieve double safety locking.
[0034] like Figure 2 and Figure 4As shown, on the basis of setting up the protective cage 1, in order to facilitate the protective cage 1 to be hung on the crossbar a of the fence at a high altitude near the edge, a hook 3 can be set on the protective cage 1. In order to ensure the stability of the hanging, the hook 3 can be divided into two groups and both are set on the connecting rod 101 located above. When in use, the hook 3 can be directly hung on the horizontal crossbar a of the fence, and the position of the protective cage 1 can be locked. In order to enable the protective cage 1 to be hung on the inclined crossbar a of the fence and realize the welding operation there, a fastener 4 can be set on the hook 3; specifically, the fastener 4 includes a tightening bolt threaded on the hook 3, and one end of the tightening bolt extends into the inside of the hook 3. When the hook 3 is hung on the inclined crossbar a, the tightening bolt can be tightened until the end of the tightening bolt contacts the inclined crossbar a, thus achieving the position locking of the protective cage 1.
[0035] like Figure 4 As shown, based on the provision of hook 3, in order to allow the protective cage 1 to be adjustable at a corresponding height, hook 3 is provided, which is composed of a straight rod portion 301 and a curved rod portion 302. Fastener 4 is provided on curved rod portion 302, and straight rod portion 301 is provided as a telescopic structure. Utilizing the telescopic straight rod portion 301, the protective cage 1 can be adjusted within a certain height range, further expanding the applicable range of the protective cage 1. The telescopic structure herein is a conventional arrangement in the prior art, such as a telescopic rod, etc., and will not be described in detail herein to avoid tediousness.
[0036] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
