Abstract

This utility model relates to the field of pork and ham curing technology, specifically to a pork and ham curing rack, comprising symmetrically arranged connecting crossbars, with through holes in the middle of the connecting crossbars. Supporting crossbars pass through the two through holes to form a main load-bearing beam. The outer periphery of the supporting crossbars has strip-shaped grooves and adjacent wedge grooves. A locking screw is vertically installed on the radially outer side of the connecting crossbars. When the locking screw is tightened, its end abuts against the bottom surface of the groove, achieving axial and circumferential rigid constraint on the supporting crossbars. Prefabricated hooks are adapted to the wedge grooves for sliding installation. When the supporting crossbar passes through the connecting crossbars, both ends of its body are physically limited by the solid structure of the connecting crossbars. The hooks are permanently constrained within the working section between the two connecting crossbars, allowing only sliding adjustment and preventing them from falling off. The weight of the hooks naturally maintains a vertical suspension state. In this structure, the supporting crossbars can be freely replaced to adapt to different load requirements; the hooks are permanently prevented from being lost through geometric limiting; the suspension posture automatically maintains vertical stability, significantly improving the reliability and operational efficiency of ham suspension.

Description

Technical Field

[0001] This utility model relates to the field of pork and ham curing technology, and in particular to a pork and ham curing rack. Background Technology

[0002] In traditional ham production, fixed metal or wooden frames are typically used for hanging and curing ham. These frames are usually welded as a single unit or bolted together, and their shape and size are fixed after production. This method has significant limitations: firstly, the large, fixed-volume frames continuously occupy a significant amount of storage space during the off-season, resulting in inefficient space utilization; secondly, the hanging points on the frames are pre-set and fixed, making it impossible to flexibly adjust the hook positions according to the size, shape, or quantity of the hams, thus limiting the flexibility of hanging. Therefore, how to achieve convenient storage of the frames and adjustable hook positions has become a practical problem that needs to be solved.

[0003] To address the shortcomings of the aforementioned fixed racks, a triangular telescopic pickling rack technology has emerged. This technology provides stability through multiple sets of foldable triangular support legs. Its core idea lies in utilizing a rotatable connection structure between the support legs, allowing it to switch between a compact folded state and a stable extended working state, effectively solving the problem of excessive storage space occupation. Simultaneously, the main suspension rods of this rack are typically designed as telescopic structures (e.g., using a sleeve rod with locking bolts), allowing users to adjust the rod length or height within a certain range to roughly adapt to different loading needs and space constraints. Some of these rods are also equipped with hooks or clip-on hooks that can slide along the rod, enabling limited positional adjustment along its length, aiming to improve the flexibility of the hook layout.

[0004] While triangular telescopic frame structures offer improvements in ease of deployment and longitudinal dimension adjustment, their pole structure design still introduces new limitations. Firstly, the suspension poles on these frames are mostly tightly integrated or fixedly matched with specific support leg structures (such as sleeve poles with connecting mechanisms), lacking the flexibility to be freely interchangeable. Users can only use the original, fixed type and length of poles. This prevents solutions for special length requirements, different load requirements, or the deployment of multiple parallel poles for layered loading on the same support structure. The root cause lies in the fact that pole installation relies on pre-defined, proprietary interfaces (such as sleeve inner diameter and locking bolt positions), lacking a universal, standardized connection mechanism adaptable to various pole sizes. Secondly, while the commonly used sliding hooks or clips on the poles are adjustable, their fixing methods rely on friction locking or simple mechanical clamping force. Under prolonged loads, especially when moving mobile frames or carrying heavy hams, these hooks are prone to slippage, displacement, or accidental loosening and falling off. The main reason is that their fixing mechanism is insufficient to withstand continuous loads and vibrations, failing to provide reliable, secure vertical restraint, posing a safety and efficiency hazard. This necessitates a solution that allows for easy rod replacement while ensuring the long-term stability and prevents loosening of the adjustable hook. Utility Model Content

[0005] The purpose of this utility model is to provide a pork and ham curing rack, which solves the problem that the suspension rods in the existing triangular telescopic racks cannot be freely replaced with different specifications of rods according to usage needs due to the fixed integrated structure. At the same time, it overcomes the defect that the sliding hooks are prone to displacement and loosening under long-term load and vibration.

[0006] To achieve the above objectives, this utility model provides a pork and ham curing rack, including symmetrically arranged connecting crossbars. A through hole is parallel to the middle of each connecting crossbar, and a supporting crossbar is parallel to the through hole. Locking screws are vertically installed on the radial outer sides of each connecting crossbar via threads. The ends of the locking screws abut against the bottom surface of a groove. The groove is located on the radial outer side of the supporting crossbar. A wedge groove is formed on the radial outer side of the supporting crossbar opposite to the groove, and a hook is slidably installed within the wedge groove.

[0007] The connecting crossbar has symmetrical rotating plates installed at both ends. The rotating plates are installed in the rotating grooves by pins. The rotating grooves are respectively opened at the top of the support sleeve.

[0008] The support sleeve rods are in two sets, each set consisting of two rods with a connecting rod fixedly installed between them. The radial outer sides of the two support sleeve rods are respectively fitted with hanging plates via pins.

[0009] The mounting plate is provided with several locking holes spaced apart. The locking holes are engaged with the outer side of the assembly screw. The assembly screw is fixedly installed on the radial outer side of the other two support sleeves and is provided with assembly nuts through threads.

[0010] The bottom end of the support sleeve is fitted with threaded rods, and the bottom end of each threaded rod is fixedly fitted with a foot.

[0011] This utility model discloses a pork and ham curing rack, which achieves modular suspension through a symmetrically arranged connecting crossbar and a detachable supporting crossbar. The two connecting crossbars have parallel horizontal through holes in their middle sections, and the supporting crossbar slides through these two through holes to form the main suspension beam. The supporting crossbar has two key features on its radially outer side: an axially extending strip-shaped groove and a wedge-shaped sliding groove (i.e., a wedge groove) formed by parallel grooves. A locking screw, perpendicular to the through hole, is screwed into the radial direction of the connecting crossbar. When the end of the screw is tightened to fully abut the bottom surface of the groove, a double constraint is formed—preventing axial movement of the supporting crossbar within the through hole and resisting circumferential rotation of the supporting crossbar through the sidewall of the groove.

[0012] After assembling a sliding suspension hook within the wedge groove of the support crossbar, its operating mechanism is as follows: when the support crossbar passes through two sets of connecting crossbars, the physical structure of the connecting crossbars naturally forms an axial physical barrier, permanently confining the hook within the area of ​​the rod body between the two sets of connecting crossbars. Under this structure, the hook can slide freely along the length of the rod body under the guidance of the wedge groove, while the hook body itself naturally maintains a vertical suspension posture due to gravity. The technical effects are mainly manifested in three breakthroughs: firstly, the support crossbar can be quickly disassembled and replaced, allowing users to replace rods of different lengths or load-bearing specifications as needed; secondly, the hook is always within the effective section of the confined rod body, never falling off or being lost under conditions of vibration or handling; thirdly, the hook in the suspended state always maintains a naturally stable vertical downward posture, ensuring the vertical suspension stability of heavy objects such as hams without additional adjustment.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1-4 .

[0021] This utility model provides a pork and ham curing rack. A rotating plate 108 is installed in the rotating groove 109 at the top of the support sleeve 110 via a pin. The other end of the rotating plate 108 is fixedly connected to both ends of the connecting crossbar 101 to form a rotatable structure, realizing the folding or unfolding function of the support sleeve 110 and the connecting crossbar 101. A support crossbar 103 is inserted through the through hole 102 in the middle of the connecting crossbar 101 to form the main load-bearing frame. The groove 105 on the radially outer side of the support crossbar 103 and the locking screw 104 installed on the radially outer side of the connecting crossbar 101 via a threaded connection form a matching relationship. When the locking screw 104 is tightened so that its end abuts the bottom surface of the groove 105, the axial displacement of the support crossbar 103 is restricted and anti-torsional constraint is provided. A sliding hook 107 is embedded in the wedge groove 106 on the support crossbar 103 located next to the groove 105. The locking screw 104 ensures that the hook 107 always maintains a vertical suspension posture.

[0022] A threaded rod 115 is threadedly installed inside the bottom end of the support sleeve rod 110. The bottom end of the threaded rod 115 is fixedly connected to a foot 116, forming an adjustable support structure. Rotating the threaded rod 115 can adjust the height of a single point to adapt to uneven ground. Each group of two support sleeve rods 110 forms a rigid support unit through a horizontally fixed connecting rod 117. In the unfolded state, one group of support sleeve rods 110 is radially outwardly rotated and unfolded via a hanging plate 111 mounted on a pin. The locking holes 112 on the surface of the hanging plate 111 are fixedly installed radially outwardly with the assembly screws of the other group of support sleeve rods 110. The rod 113 is fixed by a snap-fit, and the assembly nut 114 on the assembly screw 113 is tightened to make the hanging plate 111 and the assembly screw 113 form a locking structure, which forcibly maintains the unfolding angle of the two sets of support sleeve rods 110, and enhances the overall stability through the triangular mechanical structure; in the final main frame, the hook 107 slidably installed in the wedge groove 106 provides the vertical suspension support point for the ham, and the part of the support crossbar 103 that passes through the two connecting crossbars 101 and is exposed outside the through hole 102 forms an auxiliary suspension area, realizing the multi-position and multi-level suspension and pickling function.

[0023] Working principle: During operation, first unfold the support components. At this time, hold the support sleeve 110 and rotate it under the pin connection via the rotating plate 108, driving the base feet 116 to open outward to form a stable triangular support base. Then, adjust the threaded rod 115 at the bottom of the support sleeve 110 to finely adjust the height of each base foot 116, ensuring that the overall frame can maintain horizontal stability under different ground conditions. After the frame posture is fixed, assemble the support crossbars 103. Take one support crossbar 103 and pass it parallel to the through hole 102 of a connecting crossbar 101. With the support crossbar 103 partially inserted, slide the hook 107 into the wedge groove 106 on its radial outer side to complete the pre-installation of the hook 107. Then, continue to pass the support crossbar 103 into the corresponding through hole 102 of another connecting crossbar 101 to achieve the through-and-through erection of the support crossbar 103. Then, tighten the locking screws 104 on the radial outer side of each connecting crossbar 101, with their ends precisely abutting against the support crossbar 101. At the bottom of the groove 105 on the surface of 03, this action not only firmly locks the support crossbar 103 into the through hole 102, but more importantly, the limiting effect of the groove 105 ensures that the hook 107 always maintains the ideal vertical downward posture, completely avoiding the problem of hook 107 tilting due to gravity or load; in order to strengthen the overall structural rigidity after unfolding, the hanging plate 111 on the support sleeve 110 needs to be rotated so that its opening accurately engages with the assembly screw 113 of the other side of the support sleeve 110. After tightening the assembly nut 114, the hanging plate 111 and the screw form a strong clamp, so that all the legs maintain the preset angle and cannot retract. At this time, the geometric stability of the triangular support structure is fully guaranteed. The final frame provides multi-level hanging points: the hook 107 pre-installed in the wedge groove 106 can hang heavy objects such as ham, and its vertical state ensures balanced load-bearing; users can also directly hang the external hook 107 or the hanging rope on the exposed section of the support crossbar 103, which greatly expands the compatibility of the types and quantities of pickled products.

[0024] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
