Description

Technical Field

[0001] The utility model relates to the field of woodworking tools, in particular to a light lifting saw horse. Background Art

[0002] A saw horse is a tool used to fix wood for sawing. In ancient times, a saw horse consisted of a wooden main beam and four wooden legs. The four wooden legs were installed at the bottom of the wooden main beam to support the wooden main beam. One end of the wood was placed on the main beam at a certain angle to the ground to facilitate cutting of the wood.

[0003] The components of modern saw horses are generally made of bent metal sheets and then assembled. Such saw horses have stronger load capacity, higher stability and corrosion resistance than traditional wooden saw horses.

[0004] In outdoor projects, a foldable saw horse is often used. This saw horse is light in weight and easy to carry, which is very suitable for non-professional purposes such as outdoor camping and DIY projects. In certain cases, it is necessary to use at least two saw horses and place work boards on the saw horses to form a workbench. The height of the saw horse is determined according to different usage requirements so that the work can be easily completed on the workbench. In patent number "CN211289185U", a "light saw horse with pendant" is disclosed. This saw horse has foldable legs, but no height adjustment capability and a relatively simple function. Utility Model Content

[0005] In view of the defects of the prior art, the technical problem to be solved by the utility model is to provide a light lifting saw horse, which can effectively increase the height of the saw horse, maintain the portability of the saw horse, adapt to different working environments, and realize the height adjustment function of the saw horse.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A light lifting saw horse comprises a main beam and a supporting assembly. The main beam is hollow and a component opening is provided at the bottom of the main beam. The supporting assembly comprises a supporting rod, a sliding rod and a locking pin. The supporting rod is a hollow rod. One end of the supporting rod is rotatably installed in the component opening. The sliding rod is slidably installed at the other end of the supporting rod. A pin hole is provided at the end of the supporting rod. The locking pin can be telescopically installed in the pin hole. The sliding rod is provided with at least two positioning holes. The locking pin fixes the pin hole and the positioning hole.

[0008] With such a structure, the locking pin is retractably installed in the support rod. When the locking pin is pressed to a certain extent, the sliding rod can slide on the support rod and slide into another positioning hole. At this time, the locking pin pops out to adjust the height of the support assembly and the height of the saw horse. The support rod can rotate in the main beam, and the support rod and the sliding rod can be stored in the main beam, which reduces the volume of the saw horse and makes it portable. It effectively increases the height of the saw horse and maintains the portability of the saw horse, adapts to different working environments, and realizes the height adjustment function of the saw horse.

[0009] Preferably, an energy storage part extends from one end of the locking pin, and the energy storage part is U-shaped and installed in the support rod. The energy storage part pushes out the locking pin and locks it in the pin hole and the positioning hole, and enables the locking pin to have the performance of being pressable and resilient. The U-shaped design can stably install the energy storage part in the support rod, thereby improving stability.

[0010] Preferably, locking pins are provided at both ends of the energy storage part. The locking pins on both sides can simultaneously resist the positioning holes and pin holes on the left and right sides, preventing a single locking pin from failing to withstand the weight carried by the saw horse, thereby improving the load limit.

[0011] Preferably, the end of the locking pin is in an arc shape, which can make the positioning pin more easily disengage from the positioning hole, thus reducing the difficulty of operation.

[0012] Preferably, the saw horse further comprises a cover, which is mounted on one end of the sliding rod, is hollow, and is slidably mounted on the support rod. The support rod and the sliding rod are made of metal, and direct friction will scratch the surface and reduce the life. The cover is made of wear-resistant non-metallic material, which reduces the sliding resistance and increases the life of the saw horse.

[0013] Furthermore, the cover is made of synthetic resin. The injection molding process of synthetic resin can accurately control the tolerance, so that the clearance between the cover and the support rod is reduced, preventing particles from entering and scratching the support rod, and further increasing the life of the saw horse.

[0014] As a preference, it further comprises a bearing seat, which is detachably mounted on the side of the main beam. When multiple saw horses are used and a working board is arranged on top, a wooden strip is usually arranged under the working board, and the wooden strip is placed between the bearing seat and the main beam to limit the working table and improve the stability of the working table.

[0015] Preferably, the locking pin is also arranged at the other end of the support rod, and two fixing holes with the same center are arranged on the main beam, and the locking pin is fixed in the support rod and the fixing hole. When the support rod is opened, the locking pin pops out of the support rod and inserts into the fixing hole to achieve the function of fixing the support rod and the main beam. When the support rod is stored in the main beam, the locking pin pops out of the support rod and inserts into another fixing hole to prevent the support rod from falling.

[0016] As a preferred embodiment, the utility model further comprises an anti-skid pad, which is installed at the bottom of the sliding rod. The anti-skid pad provides anti-skid capability for the saw horse and improves the stability of the saw horse.

[0017] As a preference, the utility model further comprises a handle, which is mounted on the top of the main beam. Such a handle can easily lift the saw horse after the saw horse is folded, thereby improving the portability of the saw horse.

[0018] In summary, such a lightweight lifting saw horse can effectively increase the height of the saw horse, maintain the portability of the saw horse, adapt to different working environments, and fully realize the height adjustment function of the saw horse. BRIEF DESCRIPTION OF THE DRAWINGS
