Description

Technical Field

[0001] This utility model belongs to the technical field of commodity display equipment, and specifically relates to a stable shelf mounting buckle for commodity display equipment. Background Technology

[0002] Shelves are key components of merchandise display equipment such as freezers and shelves, used for placing and displaying goods. Some existing shelves use adjustable mounting clips. However, these clips typically employ a rotating locking mechanism. To ensure the protrusions in the locking mechanism engage smoothly, chamfers are needed on the protrusions, or the protrusions are designed to be smaller than the locking slot. This results in a significant gap between the protrusions and the locking slot, causing the mounting clips to loosen and wobble after locking onto the support bars, leading to poor shelf stability.

[0010] Furthermore, the insertion hole is a strip-shaped hole with a positioning groove at one end near the support bar. The outer end of the pin-type limiting part is provided with a positioning block. When the pin-type limiting part is locked and extended and locked onto the latch on the support position, the positioning block is locked in the positioning groove. When the pin-type limiting part unlocks the latch, the positioning block separates from the positioning groove and the pin-type limiting part can be operated to move away from the support bar in the insertion hole, controlling the latch to retract inward.

[0011] Furthermore, the surface of the positioning block is provided with a protrusion, and when the positioning block is stuck in the positioning groove (109), the protrusion is pressed and connected to the groove wall of the positioning groove.

[0012] Furthermore, an elastic element is connected to the inner end of the latch, and the elastic element presses against the cavity wall to drive the latch to extend.

[0013] Furthermore, the elastic element is a spring, one end of which is fitted onto the inner end face of the latch, and the other end is pressed against the cavity wall of the cavity.

[0014] Furthermore, the inner end face of the latch is provided with a groove, and a protruding positioning post is provided in the middle of the groove. One end of the spring is installed in the groove and sleeved on the positioning post.

[0015] The beneficial effects of this utility model are:

[0016] Through the above-mentioned technical solution, this utility model enables the latch and the support to fit tightly together, enhancing the locking stability and reliability of the latch on the support bar and improving its impact resistance. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] like Figures 1-3 As shown, the stable shelf mounting buckle of this utility model embodiment includes a buckle 100 and a support strip 200. The support strip 200 has a support slot 201 along its length. The support slot 201 is composed of protrusions and recesses on the surface of the support strip 200. For a specific structure, please refer to ZL202323427220.6 (patent title: A Shelf Support Slide Rail), which will not be described in detail here. Of course, the support slot 201 can also be a through hole on the surface of the support strip 200, or a slot formed by two adjacent protrusions on the surface of the support strip 200 (such as the protrusions in ZL202323427220.6).

[0023] The buckle 100 is slidably mounted on the support bar 200; the buckle 100 has a latch 101 inside, which can retract inward and extend from the side surface facing the support bar 200 and fit into the support locking position 201 to achieve locking of the buckle 100; Figure 1 As shown, the support slot 201 is a square slot composed of a protrusion and a recess, and the latch 101 is a square latch that matches the shape and size of the square slot. The latch 101 is inserted linearly and fits snugly onto the support slot 201 without the need for clearance, thus improving the tightness of the fit between the latch 101 and the support slot 201, and further enhancing the locking stability and reliability of the buckle 100 on the support bar 200. The buckle 100 also has a pin-type limiting part 102, which extends from the outer surface of the buckle 100 and connects to the latch 101. It is used to lock the latch 101 that extends out and fits onto the support slot 201, unlock the latch 101, and control the latch 101 to retract inward until it separates from the support slot 201. The specific structure can be:

[0024] The buckle 100 has a cavity 107 with one end connected to the surface facing the support bar 200. The latch 101 is retractably fitted into the cavity 107. The inner end of the latch 101 is connected to an elastic element 112, which presses against the cavity wall of the cavity 107 to drive the latch 101 to extend. More specifically, the elastic element 112 is a spring, one end of which is fitted to the inner end face of the latch 101, and the other end presses against the cavity wall of the cavity 107. The inner end face of the latch 101 has a groove 113, and a protruding positioning post 114 is provided in the middle of the groove 113. One end of the spring is installed in the groove 113 and sleeved on the positioning post 114. Preferably, the positioning post 114 and the groove 113 are coaxial with the latch 101 to further improve the movement stability of the latch 101.

[0025] The outer surface of the buckle 100 is provided with an insertion hole 108. The inner end of the insertion hole 108 is connected to the cavity 107. The pin-type limiting part 102 is axially movable and installed in the insertion hole 108, extending into the cavity 107 and connected to the latch 101. The latch 101 is provided with an assembly hole 103. One end (the inner end) of the pin-type limiting part 102 extending into the buckle 100 is assembled in the assembly hole 103 and can move inward and outward within the assembly hole 103 to lock the latch 101 in the extended state or unlock the latch 101 and control its retraction. Specifically, the insertion hole 108 is a strip-shaped hole, and its end near the support bar 200 is provided with a positioning groove 109. The outer end of the pin-type limiting part 102 is provided with a positioning block 110. When the pin-type limiting part 102 is in the extended state, the positioning block 110 is positioned to lock the latch 101 in the extended state or to unlock the latch 101 and control its retraction. When the locking part 102 locks the latch 101, which extends and engages with the support slot 201, the positioning block 110 engages within the positioning groove 109. When the pin-type limiting part 102 unlocks the latch 101, the positioning block 110 separates from the positioning groove 109, and the pin-type limiting part 102 can be operated to move away from the support bar 200 within the insertion hole 108, controlling the latch 101 to retract inward, thus separating the latch 101 from the support slot 201, unlocking the buckle 100, and allowing the buckle 100 to slide and adjust its position on the support bar 200. Furthermore, the surface of the positioning block 110 is provided with a protrusion 111. When the positioning block 110 is engaged within the positioning groove 109, the protrusion 111 is pressed against the groove wall of the positioning groove 109, preventing the pin-type limiting part 102 from automatically disengaging and improving the locking stability of the pin-type limiting part 102.

[0026] Furthermore, the inner wall of the assembly hole 103 is provided with a boss 104, and one end of the pin-type limiting part 102 that extends into the buckle 100 is provided with a buckle 105. When one end (inner end) of the pin-type limiting part 102 moves outward, the buckle 105 connects with the boss 104, so that the pin-type limiting part 102 remains connected to the latch 101 when unlocking the latch 101, preventing it from loosening or falling off and improving the ease of operation. Preferably, the left and right sides of one end of the pin-type limiting part 102 that extends into the buckle 100 are provided with buckles 105, and a gap 106 is provided between the buckle 105 and the end of that end, which improves the deformability of the buckle 105 and facilitates the assembly and disassembly between the pin-type limiting part 102 and the latch 101.

[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
