Description

Technical Field

[0001] The utility model relates to the technical field of support tools, in particular to a triangular support frame. Background Art

[0002] In the production and manufacturing process of workpieces, various processing equipment is often required to process the workpieces. When using the processing equipment to process the workpieces, it is necessary to first support and fix the workpieces so that a certain working space is formed between the workpieces and the ground, and then use the processing equipment to process the supported and fixed workpieces. For example: in industries such as construction site construction, woodworking production, building operations, and mold manufacturing, processing operations such as polishing, grinding, lapping, and waxing need to be carried out on large workpieces. Since the workpieces are relatively large in volume and heavy in weight, support tools are required to support the workpieces to meet different working requirements.

[0003] In the existing patent, the Chinese patent document with the application number 201620675013.3 discloses a support frame capable of limiting the supporting force, including a base, a guiding device, a placing block, and a pressing cover. The guiding device is vertically arranged on the top of the base, the placing block is arranged on the top of the guiding device, a placing groove is arranged on the placing block, and both ends of the pressing cover are correspondingly connected to the placing block. Since the height position of the workpiece in this patent document is self-adaptive according to its own weight, the height for supporting the workpiece cannot be fixed, resulting in poor stability of the supported workpiece and being unfavorable for operating on the supported workpiece.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Summary of the Utility Model

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a triangular support frame.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A triangular support frame includes a cross bar, a longitudinal bar, an isosceles triangular bracket, an inclined bar, a slider, a locking member, and a support head. Both ends of the cross bar are respectively connected to the middle of the base of the isosceles triangular bracket and the middle of the longitudinal bar. Both ends of the inclined bar are respectively connected to the top angle of the isosceles triangular bracket and the middle of the longitudinal bar. The slider is slidably connected to the inclined bar, the support head is detachably connected to the slider, and the locking member is used to lock the slider on the inclined bar. The inclined bar, the cross bar, and the isosceles triangular bracket enclose a triangular structure.

[0008] Further, the slider is a sliding sleeve, and the sliding sleeve is slidably sleeved outside the inclined bar.

[0009] Further, the diagonal rod is provided with a plurality of jacks which are distributed along the inclined direction of the diagonal rod. The sliding sleeve is provided with locking holes for communicating with the jacks, and the locking member is detachably inserted into the jacks and the locking holes.

[0010] Further, the locking member includes a pull ring, a limiting rod and an insertion shaft which are connected in sequence. The limiting rod is perpendicular to the insertion shaft. The insertion shaft is used for inserting into the jacks and the locking holes, and the limiting rod is used for abutting against the top surface of the diagonal rod or / and the side surface of the slider.

[0011] Further, the included angle between the diagonal rod and the isosceles triangle bracket is 90°.

[0012] Further, a reinforcing rib is arranged in the middle of the isosceles triangle bracket, and both ends of the reinforcing rib are respectively connected to the two waists of the isosceles triangle bracket.

[0013] Further, anti-slip pads are arranged on the bottom surface of the vertical rod and the bottom surface of the base of the isosceles triangle bracket.

[0014] Further, an anti-slip pad is arranged on the bottom surface of the cross rod.

[0017] Advantages of the present utility model: In practical applications, after the supporting head is installed on the slider, the position of the supporting head on the inclined rod is adjusted by sliding the slider on the inclined rod, thereby adjusting the height of the supporting head. After the adjustment is completed, the slider is locked on the inclined rod through the locking member, thus realizing the locking of the supporting head. When one end of the workpiece needs to be supported, first raise one end of the workpiece and then place it on the supporting head, so that the supporting head supports one end of the workpiece, and the ground supports the other end of the workpiece, enabling the workpiece to be supported obliquely; when both ends of the workpiece need to be supported, first raise the entire workpiece, then place two of the present triangular support frames opposite to each other under the workpiece, and finally place the workpiece on the supporting heads of the two triangular support frames to lift the workpiece off the ground. Among them, the supporting head is detachably connected to the slider, and according to the supporting requirements of different workpieces, supporting heads with different shapes and structures can be replaced. In addition, by adjusting the position of the supporting head on the inclined rod, different heights of the supporting head can be adjusted, so that the workpiece can be supported at different heights or at different placement angles, and thus different requirements for operating on the workpiece can be met. The structure of the present utility model is simple and stable, with strong supporting stability, not easily deformed, and the height of the supporting head is adjustable to obtain different supporting heights, thus creating favorable operating conditions for actual needs. The present utility model is particularly suitable for supporting heavy and large-sized workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] For the convenience of those skilled in the art, the present utility model will be further described below in conjunction with embodiments and drawings. The content mentioned in the embodiments does not limit the present utility model.

[0026] As Figures 1 to 5 shown, a triangular support frame provided by the present utility model includes a cross bar 1, a longitudinal bar 2, an isosceles triangular bracket 3, an inclined bar 4, a slider 5, a locking member 6, and a support head 7. The two ends of the cross bar 1 are respectively connected to the middle of the base of the isosceles triangular bracket 3 and the middle of the longitudinal bar 2. The two ends of the inclined bar 4 are respectively connected to the top angle of the isosceles triangular bracket 3 and the middle of the longitudinal bar 2. The slider 5 is slidably connected to the inclined bar 4. The support head 7 is detachably connected to the slider 5. The locking member 6 is used to lock the slider 5 on the inclined bar 4. The inclined bar 4, the cross bar 1, and the isosceles triangular bracket 3 enclose a triangular structure.

[0027] In practical applications, after the support head 7 is installed on the slider 5, the slider 5 slides on the inclined bar 4 to adjust the position of the support head 7 on the inclined bar 4, thereby adjusting the height of the support head 7. After the adjustment is completed, the slider 5 is locked on the inclined bar 4 through the locking member 6, thereby realizing the locking of the support head 7. As Figure 4 shown, when one end of the workpiece needs to be supported, first raise one end of the workpiece and then place it on the support head 7, so that the support head 7 supports one end of the workpiece, and the ground supports the other end of the workpiece, so that the workpiece can be supported obliquely; as Figure 5 shown, when both ends of the workpiece need to be supported, first raise the entire workpiece, then place two or more of the present triangular support frames relatively under the workpiece, and finally place the workpiece on the support heads 7 of two or more triangular support frames to lift the workpiece off the ground. Among them, the support head 7 is detachably connected to the slider 5. According to the support requirements of different workpieces, support heads 7 with different shapes and structures can be replaced. In addition, by adjusting the position of the support head 7 on the inclined bar 4, the different heights of the support head 7 can be adjusted, so that the workpiece can be supported at different heights or placement angles, and thus different requirements for operating on the workpiece can be met. The structure of the present utility model is simple and stable, with strong support stability, not easily deformed, and the height of the support head 7 is adjustable to obtain different support heights, thereby creating favorable operating conditions for actual needs. The present utility model is particularly suitable for supporting heavy and large-volume workpieces.

[0028] In this embodiment, the slider 5 is a sliding sleeve, and the sliding sleeve is slidably sleeved outside the inclined bar 4. This structural design can not only improve the sliding stability of the slider 5 relative to the inclined bar 4, but also prevent the slider 5 from detaching from the inclined bar 4.

[0029] In this embodiment, the diagonal rod 4 is provided with a plurality of jacks 8, and the plurality of jacks 8 are distributed along the inclined direction of the diagonal rod 4. The sliding sleeve is provided with a locking hole 18 for communicating with the jack 8, and the locking member 6 is detachably inserted into the jack 8 and the locking hole 18. After the slider 5 drives the supporting head 7 to move to the required position, the locking hole 18 of the slider 5 communicates with one of the jacks 8 on the diagonal rod 4. At this time, the locking member 6 is inserted into the jack 8 and the locking hole 18, and the slider 5 can be locked on the diagonal rod 4, thereby locking the supporting head 7.

[0030] In this embodiment, the locking member 6 includes a pull ring 9, a limiting rod 10, and an insertion shaft 11 that are connected in sequence. The limiting rod 10 is perpendicular to the insertion shaft 11. The insertion shaft 11 is used to be inserted into the jack 8 and the locking hole 18, and the limiting rod 10 is used to abut against the top surface of the diagonal rod 4 or / and the side surface of the slider 5. With this structural design of the locking member 6, it is convenient for the operator to disassemble and assemble the locking member 6.

[0031] In this embodiment, the included angle between the diagonal rod 4 and the isosceles triangle bracket 3 is 90°. With this structural design, the structure of this triangular support frame is more stable.

[0032] In this embodiment, a reinforcing rib 12 is provided in the middle of the isosceles triangle bracket 3, and both ends of the reinforcing rib 12 are connected to the two waists of the isosceles triangle bracket 3 respectively. With this structural design, the strength of the isosceles triangle bracket 3 is enhanced, and thus the structure of the triangular support frame is more stable.

[0033] In this embodiment, anti-slip pads 13 are provided on the bottom surface of the vertical rod 2 and the bottom surface of the base of the isosceles triangle bracket 3, and anti-slip pads 13 are provided on the bottom surface of the cross rod 1. The anti-slip pads 13 not only play a role in anti-slip, but also play a role in buffering protection and reducing noise.

[0034] In this embodiment, the supporting head 7 is detachably connected to the slider 5 via a detachable structure 14; specifically, the detachable structure 14 includes a bolt assembly 15 and two locking plates 16. Cavities 17 are provided on both sides of the slider 5, and the two locking plates 16 are respectively accommodated in the two cavities 17 of the slider 5. The slider 5 and the supporting head 7 are both clamped between the two locking plates 16, and the bolt assembly 15 is used to lock the slider 5, the supporting head 7, and the two locking plates 16 together. With this structural design, it is not only convenient for the disassembly, assembly and replacement of the supporting head 7, but also enables the supporting head 7 to be firmly installed on the slider 5.

[0035] All the technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
