Description

Technical Field

[0001] This utility model relates to the technical field of waterproof frames for e-ink displays, specifically a waterproof frame for e-ink displays of electronic price tags. Background Technology

[0002] A waterproof frame for electronic shelf label ink screens is a waterproof frame used for mounting the outer side of electronic shelf label ink screens.

[0003] Based on the above, the inventors have discovered that: Currently, there are many waterproof frames for e-ink screens of electronic shelf labels on the market. However, the waterproof frames for e-ink screens of general electronic shelf labels are installed by snapping the frame to the e-ink body, which allows moisture to corrode the connection between the two, causing the inside of the e-ink to become damp. In severe cases, this can cause short circuits in the e-ink. Furthermore, the connection between the frame holding the e-ink and the protective cover is not stable and is prone to detachment, thereby reducing the protective effect of the waterproof frame on the outside of the e-ink and reducing the practicality of the device. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a waterproof frame for e-ink screens of electronic shelf labels, in order to achieve a more practical purpose. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a waterproof frame for an e-ink screen of an electronic price tag, comprising a frame body, a surrounding plate fixed to the top of the frame body, a protective mechanism provided at the top of the frame body, and an installation mechanism provided on the outer wall of the protective mechanism;

[0006] The protective mechanism includes:

[0007] A waterproof cover is provided at the top of the frame. The inner wall of the waterproof cover is provided with a waterproof protrusion. A ring plate is fixed at the top of the waterproof protrusion. The ring plate is located at the top of the waterproof cover. Two limiting blocks are fixed at the bottom of the waterproof cover. Two limiting grooves are opened at the top of the frame. The inner walls of the two limiting grooves are matched with the outer walls of the limiting blocks.

[0008] As a preferred embodiment of this utility model, groove blocks are fixed on both sides of the frame, and recesses are provided on the inner walls of the two groove blocks, with the two recesses located at the top of the waterproof cover.

[0009] As a preferred embodiment of this utility model, four cylinders are fixed at the bottom of the ring plate, and four circular grooves are provided at the top of the waterproof cover. The inner walls of the four circular grooves are matched with the outer walls of the cylinders.

[0010] As a preferred embodiment of this utility model, the installation mechanism includes:

[0011] Two protrusions are provided, the outer walls of which are matched with the inner walls of the limiting blocks. The inner walls of the two limiting grooves are provided with sliding grooves, and the inner walls of the two sliding grooves slide against the outer walls of the protrusions. A connecting rod is fixed on one side of each of the two protrusions, and the outer walls of the two connecting rods are fitted with the inner walls of the sliding grooves.

[0012] As a preferred embodiment of this utility model, springs are fitted on the outer walls of both connecting rods, one end of each spring is fixed to one side of the protrusion, and the other end of each spring is fixed to the inner wall of the groove.

[0013] As a preferred embodiment of this utility model, a fixing plate is fixed to one end of each of the two connecting rods, and the fixing plate is disposed on one side of the frame.

[0014] As a preferred embodiment of this utility model, the inner walls of both recesses are provided with insert posts, and the outer walls of both insert posts are matched with the inner walls of the frame.

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

[0016] 1. This solution controls the separation between the fixed plate and the frame, allowing the connecting rod to be fitted onto the inner wall of the slide groove. This drives the protrusion to slide along the inner wall of the slide groove while simultaneously compressing and retracting the spring, thus installing the waterproof cover at the top of the frame. The limiting block fixed at the bottom of the waterproof cover engages with the inner wall of the limiting groove. Releasing the control of the fixed plate allows the spring's return contraction force to drive the protrusion until it inserts into the inner wall of the limiting block, securing the waterproof cover firmly at the top of the frame. This prevents moisture from penetrating into the ink screen body installed on the inner wall of the frame, facilitating the normal use of the device.

[0017] 2. This solution involves matching the outer wall of the waterproof protrusion with the inner wall of the waterproof cover, and simultaneously installing a ring plate on the top of the waterproof protrusion. The cylinder fixed at the bottom of the ring plate is inserted into the circular groove, thus securing the ring plate firmly to the top of the waterproof cover. This further blocks moisture adsorbed on the ink screen, improving the device's waterproofing effect. A recessed block is placed on the top of the waterproof cover, with its outer wall engaging with the inner wall of the groove. The outer wall of the insert is then fitted onto the inner wall of the recessed block until it matches the inner wall of the frame, further reinforcing the stability of the connection between the frame and the waterproof cover, effectively improving the device's performance.

Detailed Implementation

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figures 1-5 As shown, the present invention provides a waterproof frame for an electronic price tag ink screen, including a frame 1, a surrounding plate 2 fixed to the top of the frame 1, a protective mechanism 3 at the top of the frame 1, and an installation mechanism 4 on the outer wall of the protective mechanism 3.

[0027] Protective mechanism 3 includes:

[0028] A waterproof cover 31 is installed at the top of the frame 1. The inner wall of the waterproof cover 31 is provided with a waterproof protrusion 32. A ring plate 33 is fixed at the top of the waterproof protrusion 32. The ring plate 33 is installed at the top of the waterproof cover 31. Two limiting blocks 34 are fixed at the bottom of the waterproof cover 31. Two limiting grooves 35 are opened at the top of the frame 1. The inner walls of the two limiting grooves 35 are matched with the outer walls of the limiting blocks 34. Four cylinders 36 are fixed at the bottom of the ring plate 33. Four circular grooves 37 are opened at the top of the waterproof cover 31. The inner walls of the four circular grooves 37 are matched with the outer walls of the cylinders 36.

[0029] As attached Figure 1 and Figure 2 As shown, groove blocks 5 are fixed on both sides of the frame 1. The inner walls of the two groove blocks 5 are provided with recesses 6. The two recesses 6 are set at the top of the waterproof cover 31. The inner walls of the two recesses 6 are provided with inserts 7. The outer walls of the two inserts 7 are matched with the inner walls of the frame 1 to improve the stability of the connection between the frame 1 and the waterproof cover 31.

[0030] As attached Figure 3 , Figure 4 and Figure 5 As shown, the mounting mechanism 4 includes:

[0031] Two protrusions 41 are provided, with their outer walls matching the inner walls of the limiting blocks 34. The inner walls of the two limiting grooves 35 are each provided with sliding grooves 42, which slide against the outer walls of the protrusions 41. A connecting rod 43 is fixed to one side of each of the two protrusions 41, with its outer wall fitting against the inner wall of the sliding groove 42. A spring 44 is fitted onto the outer wall of each connecting rod 43, with one end of each spring fixed to one side of the protrusion 41 and the other end fixed to the inner wall of the sliding groove 42.
