[0003] Traditional two -dimensional code label usually adopts adhesive, magnetic attraction or simple slot mode and is fixed on the surface of equipment, but in actual use, this kind of mode has following problems:

[0004] Label easy to fall off leads to data link breakage, food processing environment often accompanies equipment vibration, high temperature steam cleaning, oil pollution erosion or personnel miscontact etc. Complex working conditions, ordinary fixed structure is difficult to resist external interference, and the label is easy to shift or fall off, once the label is lost, the traceability information of the corresponding batch will be completely invalid, which may lead to problem food material unable to be recalled, and even cause food safety accidents;

[0005] Food material batch replacement needs to frequently replace the label, and the adhesive label is easy to leave glue stains, which takes time to clean, and the magnetic attraction or slot structure can be disassembled, but lacks a anti -drop locking mechanism, and the stability is poor in the vibration environment.

[0006] In the prior art, although some schemes increase reinforcing screws or complex claw structures to improve the fixing strength of the label, these designs often lead to complicated disassembly and assembly processes, and special tools are required for disassembly and assembly.

[0007] Therefore, a label fixing mechanism with high reliability, anti -drop and convenient disassembly and assembly ability is needed to solve the above problems. UTILITY MODEL CONTENTS

[0008] The utility model aims at providing a spring ejection mechanism of two -dimensional code label to solve the problem that the label is easy to shift or fall off in the background art.

[0009] To achieve the above object, the utility model provides the following technical scheme: a spring ejection mechanism of two -dimensional code label, comprising:

[0010] The label body is inserted into the mounting groove of the equipment shell in a stepped manner, and the equipment shell is internally provided with limit grooves corresponding to the two sides of the label body;

[0011] Horizontal extension grooves are formed in the left and right sides of the label body, and the front ends of the grooves are provided with operation windows exposed to the outside of the equipment shell;

[0012] The limiting piece is slidingly arranged in the sliding slot, and an outer end of the limiting piece is provided with a protrusion passing through the operation window;

[0013] The first spring is connected to the inner wall of the sliding slot and the limiting piece at two ends respectively, and the limiting piece is clamped into the limiting slot under normal state.

[0014] The inner wall of the equipment shell is provided with a second spring for ejecting the label body.

[0015] By adopting the above technical scheme, the limiting piece and the first spring realize the anti-disengagement locking of the label body, and the second spring provides the ejection force, so that the nested two-way locking and the ejection separation mechanism of the label body and the equipment shell are protected.

[0016] As a preferred technical scheme of the utility model, the depth difference of the mounting slot is not less than 1mm than the thickness of the label body, and a stepped nested structure is formed.

[0017] By adopting the above technical scheme, the physical limiting step is formed by the depth difference, the label body is prevented from being excessively inserted, the stepped nested structure enhances the stability of the label and the shell, and the displacement caused by vibration is resisted.

[0018] As a preferred technical scheme of the utility model, the vertical height of the operation window is less than the height of the sliding slot, and the lower edge of the operation window is flush with the bottom of the sliding slot.

[0019] By adopting the above technical scheme, the size of the operation window is limited to avoid the exposure of the spring, and the lower edge of the window is aligned with the bottom of the sliding slot, so that the force direction of the protrusion is consistent with the axis of the sliding slot when the finger exerts force, and the jamming is prevented.

[0020] As a preferred technical scheme of the utility model, the protrusion is a semispherical protrusion, and the width of the protrusion is less than the width of the operation window.

[0021] By adopting the above technical scheme, the semispherical protrusion is convenient for the finger to press and slide, the operation friction is reduced, the width limitation ensures the free movement of the protrusion in the window, and the transverse interference is avoided.

[0022] As a preferred technical scheme of the utility model, the first spring is arranged in the sliding slot in an upper and lower double-row symmetrical manner, and the compression stroke of the first spring and the sliding slot is half of the length of the limiting piece.

[0023] By adopting the above technical scheme, the double-row spring provides balanced thrust force, prevents the limiting piece from being deflected, and the compression stroke limitation ensures that the limiting piece effectively disengages from the limiting slot and avoids overloading and failure of the spring.

[0024] As a preferred technical scheme of the utility model, the protrusion of the label body is not less than 1mm and forms a pressing stress surface.

[0025] Adopting the technical scheme, the convex part serves as a force application fulcrum, facilitating the thumb to press the front end of the label body when single-handed holding, and realizing single-handed disassembly and assembly operation in cooperation with the second spring.

[0026] As the preferred technical scheme of the utility model, the depth of the limiting groove is two-thirds of the length of the outer end of the limiting piece, and the inner wall of the limiting groove is provided with a 5° inclined guide surface.

[0027] Adopting the technical scheme, the depth control ensures effective engagement of the limiting piece, and the remaining one-third prevents the limiting piece from falling out, the inclined guide surface guides the limiting piece to be smoothly clamped, and the assembly resistance is reduced.

[0028] As the preferred technical scheme of the utility model, the second spring is a conical spring, the large end of which is fixed to the equipment shell, and the small end abuts against the back of the label body.

[0029] Adopting the technical scheme, the conical spring provides progressive elastic force in a small space, low elastic force in the initial stage avoids accidental ejection, and the elastic force sharply increases in the later stage to ensure that the label is completely separated, and the size end configuration optimizes the space utilization rate.

[0030] Compared with the prior art, the spring ejection mechanism of the two-dimensional code label has the following beneficial effects:

[0031] Through the elastic clamping structure formed by the limiting piece and the first spring, in combination with the pre-tightening elastic force of the second spring, double anti-falling protection of the label body is realized, the engagement structure of the limiting piece and the limiting groove can effectively resist lateral displacement under the working conditions of equipment vibration or external force impact, the stepped nested design forms axial physical limiting, and the continuous elastic force of the second spring offsets the risk of longitudinal loosening, so that the fixing reliability of the label in a complex environment is significantly improved.

[0038] Label body 1 is inserted into the installation groove 3 of equipment shell 2 in steps, and the inside of equipment shell 2 is symmetrically provided with the limiting slot 4 corresponding to the both sides of label body 1;

[0039] The both sides of label body 1 are provided with horizontally extending slide grooves 5, and the front end of slide groove 5 is provided with an operation window 6 exposed to the outside of equipment shell 2;

[0040] The limiting piece 7 is slidably arranged in the slide groove 5, and the outer end of the limiting piece 7 is provided with a protrusion 8 passing through the operation window 6;

[0041] The both ends of the first spring 9 are connected to the inner wall of the slide groove 5 and the limiting piece 7 respectively, and the limiting piece 7 is clamped into the limiting slot 4 under normal state;

[0042] The inner wall of equipment shell 2 is provided with a second spring 10 for ejecting label body 1.

[0043] The label body 1 is a plastic support, and the surface thereof can be marked with corresponding two-dimensional code information according to actual source information. The label body 1 has a stepped rectangular structure as a whole, and the smaller part of the back thereof can be provided with corresponding electronic components to assist the label body 1 in cooperating with the equipment. The equipment shell 2 is internally provided with a mounting groove 3, the shape of which is consistent with the whole label body 1. The front end of the label body 1 protrudes outward from the inside of the mounting groove 3 by not less than 1 mm, facilitating repeated disassembly and installation. The mounting groove 3 is further provided with a limiting groove 4, which is symmetrically arranged at the left and right ends of the label body 1. The internal dimension of the limiting groove 4 is the same as the dimension of one end of a limiting piece 7, and the one end of the limiting piece 7 has a semicircular structure. The limiting piece 7 can slide along the inside of the limiting groove 4 or the equipment shell 2 to increase the contact area of the limiting piece 7, facilitating the sliding of the limiting piece 7 in or out of the limiting groove 4. The limiting piece 7 is slidingly connected to the inside of a sliding groove 5, which is symmetrically arranged at the left and right ends of the label body 1. The position of the sliding groove 5 corresponds to the position of the limiting groove 4 horizontally, and the height ratio thereof is the same. The sliding groove 5 is further provided with an operation window 6 at the front end thereof. One end of the limiting piece 7 protrudes outward, and the protruding part is a protruding block 8. The dimension of the protruding block 8 is smaller than the dimension of the operation window 6, and the operation window 6 is slidingly connected to the protruding block 8. The vertical height of the operation window 6 is smaller than the vertical height of the sliding groove 5, so that the sliding groove 5 and the operation window 6 have an overlapping part, which can be used to hide a first spring 9. The number of the first springs 9 is two, and they are symmetrically arranged upward and downward. The two ends of the first springs 9 are connected to the inside of the sliding groove 5 and one end of the limiting piece 7. When the position of the limiting groove 4 corresponds to the position of the limiting piece 7 horizontally, the compression energy of the first spring 9 resets the limiting piece 7, so that the limiting piece 7 is locked in the limiting groove 4. The equipment shell 2 is further provided with a second spring 10, which is movably connected to the protruding end of the label body 1.

[0044] When the label body 1 needs to be installed, the label body 1 is positioned corresponding to the mounting groove 3 of the equipment shell 2, and the label body 1 is pressed inward, so that the limiting pieces 7 at the left and right ends of the label body 1 are clamped into the limiting grooves 4 of the equipment shell 2. When the label body 1 needs to be disassembled, the two protruding blocks 8 are controlled to compress the first spring 9, so that the limiting piece 7 is retracted into the sliding groove 5. At this time, the second spring 10 in the equipment shell 2 pops out the label body 1 as a whole. The operation is convenient and not easy to damage, avoiding falling off during transportation and carrying, thereby increasing the practicability of the whole.
