Description

TECHNICAL FIELD

[0001] The utility model relates to the field of refrigeration box accessories, especially to a simple assembly structure of temperature sensor. BACKGROUND

[0002] In the process of manufacturing and assembling refrigeration boxes, the fixing mode of temperature sensing probes has long been faced with the dual challenges of complex process and insufficient reliability. The current mainstream fixing method in the industry mainly relies on two technical routes: one is to use a separately molded plastic clamp on the heat dissipation back plate to press the temperature sensing probe, and then tighten the clamp ends with screws to achieve the fixing purpose; the second is to directly use adhesive to adhere the probe to the surface of the heat dissipation back plate. However, both methods have significant defects, which seriously restrict production efficiency and product stability.

[0003] Firstly, the plastic clamp and screw fixing method seems intuitive, but in the actual assembly process, it exposes the problem of complicated operation and hidden risks. Specifically, the worker needs to first accurately place the temperature sensing probe at the specified position of the heat dissipation back plate, and then press it with the plastic clamp. In this process, the screw hole of the clamp and the heat dissipation back plate must be strictly aligned, even if there is a very slight deviation, it is extremely likely to scratch the back plate surface when the screw is tightened, and even cause structural damage. This not only increases the rework rate in the production process, but also indirectly increases maintenance costs due to increased maintenance needs. In addition, the cost of the special mold required for developing the plastic clamp is extremely high, which will undoubtedly further increase the production cost of single products, making it difficult for enterprises to effectively optimize costs in the highly competitive market environment.

[0004] On the other hand, the adhesive fixing method, although it omits the assembly of the clamp and screw, seems to simplify the process, but it brings new risks. In actual use, refrigeration boxes will frequently experience large temperature fluctuations, and the condensation phenomenon inside and the thermal expansion and contraction effect of the external environment will continue to act on the adhesive interface. Over time, the adhesive layer will gradually age and even peel off. Once the temperature sensing probe falls off due to the failure of the glue, the temperature control system of the refrigeration box will immediately lose its function and fall into a paralyzed state, which not only greatly affects user experience, but also may cause serious consequences and incur immeasurable losses in application scenarios that require extremely high temperature control, such as food safety or medical storage. More importantly, the adhesive process has extremely strict requirements for the operating environment, such as humidity, temperature, and cleanliness. Any factor that does not meet the standard can affect the adhesive effect. This undoubtedly further increases the difficulty and complexity of production management, and increases uncontrollable factors in the production process.

[0005] In summary, the two traditional temperature sensing probe fixing methods above achieve an effective balance among cost, efficiency and reliability. The plastic clamp fixing method relies on high-precision molds and complex assembly processes, which not only has high cost and low production efficiency, but also has poor reliability. The adhesive fixing method is limited by the durability and environmental adaptability of the material, and cannot meet the core needs of modern manufacturing for low cost, high yield and long-term stability. Therefore, a breakthrough assembly structure is needed to simplify the mold design and production process, and to realize quick installation and firm fixation of the probe through a physical limiting mechanism, thereby fundamentally solving the above technical problems. Practical new type content

[0006] The purpose of the present utility model is to provide a simple assembly structure of a temperature sensor, which directly optimizes the structure of a heat dissipation back plate, and realizes quick positioning, installation and fixation of a temperature sensing probe without adding additional auxiliary fastening parts, thereby simplifying the assembly process, reducing the cost of purchasing parts, and completely avoiding the risk of probe falling off caused by thermal expansion and contraction in the traditional adhesive process, and significantly improving the operation reliability of a refrigeration box.

[0007] In order to achieve the above purpose, the present utility model adopts the following scheme: a simple assembly structure of a temperature sensor, comprising: a heat dissipation back plate, provided with heat dissipation groove holes segmented along a ring on the surface thereof;

[0008] A plurality of positioning grooves are integrally formed on the grid between the heat dissipation groove holes, the positioning grooves are arc-shaped concave, and the diameter thereof matches the outer diameter of the temperature sensing probe;

[0009] A limiting component is arranged on the opening edge of the positioning groove or the interval grid between adjacent positioning grooves, and the limiting component and the positioning groove jointly form a channel for positioning and clamping the temperature sensing probe.

[0010] In the above scheme, the limiting component cooperates with the positioning groove to form a clamping channel, which first simplifies the mold design from the root cause, does not need to additionally open a special mold for the clamp, and avoids the cost investment of the traditional clamp in the mold; at the same time, the integrated design of integral molding optimizes the overall layout of the heat dissipation back plate, which not only retains the heat dissipation function, but also realizes quick positioning of the probe through a physical limiting channel, and eliminates the cumbersome steps of adhesive or screw fixation, thereby significantly reducing the assembly difficulty and labor cost.

[0011] As a preferred scheme of the present utility model, the limiting component comprises:

[0012] Two limiting clamping tongue pieces are symmetrically arranged on both sides of the opening of the positioning groove, and the ends of the two limiting clamping tongue pieces respectively extend towards the direction of the opposite limiting clamping tongue piece;

[0013] The first guide gap is formed between the end portions of the two limiting clamping tongue members;

[0014] The inner side wall of the limiting clamping tongue member and the inner wall of the positioning groove jointly form an annular limiting space, and the inner contour of the annular limiting space matches the outer wall of the temperature sensing probe, so that the temperature sensing probe is pressed into the positioning groove along the first guide gap.

[0015] The above scheme further enhances the positioning accuracy, and the inner side wall of the limiting clamping tongue member and the inner wall of the positioning groove form an annular limiting space, and the contour of the annular limiting space precisely matches the outer wall of the probe, so that the probe can be automatically centered without manual adjustment of the angle when the probe is inserted, thereby avoiding the error risk of aligning the screw holes in the traditional clamp installation. The design of the first guide gap allows the probe to slide into the groove through flexible extrusion, which simplifies the operation process and avoids mechanical damage to the heat dissipation back plate caused by hard assembly.

[0016] As a further scheme of the utility model, the limiting member further comprises a positioning hoop member, the positioning hoop member is arranged on the interval grid between adjacent positioning grooves, and a second guide gap capable of allowing the temperature sensing probe to be pressed into the positioning groove is arranged on the outer wall of the positioning hoop member; the inner wall of the positioning hoop member is in the form of an arc surface matching the outer wall of the temperature sensing probe, and the central axis of the positioning hoop member is coaxial with the annular limiting space formed by the inner walls of the limiting clamping tongue member and the positioning groove, so as to jointly form a continuous channel for clamping the temperature sensing probe.

[0017] As a preferred scheme of the utility model, the positioning hoop member comprises:

[0018] Two interval arranged semicircular clamping pieces, the back portions of the two interval arranged semicircular clamping pieces are respectively connected with folded and curved elastic arms;

[0019] The elastic arms are integrally injection molded with the corresponding heat dissipation groove grid;

[0020] The second guide gap is located between the end portions of the two semicircular clamping pieces.

[0021] In the above scheme, the positioning hoop member is additionally arranged on the grid between adjacent positioning grooves, the semicircular clamping piece of the positioning hoop member is integrally formed with the grid through the elastic arm, and the second guide gap is formed. The folded and curved design of the elastic arm gives the clamping piece elastic restoring force, when the probe is pressed in, the clamping piece is extruded and opened outward, and then the temperature sensing probe is clamped by the elastic arm rebound force; the introduction of the second guide gap expands the assembly path of the probe, so that the probe can be transferred from the limiting clamping tongue member to the positioning hoop member along the continuous channel, forming a multi-stage limiting structure, which effectively prevents the temperature sensing probe from axial movement under vibration or temperature change.

[0022] As a further aspect of the utility model, the inner side arc wall surface of the semicircular clamping piece is provided with a plurality of soft rubber friction strips, the friction strip is composed of soft rubber material, the base is embedded in the inner wall of the semicircular clamping piece, and the soft rubber friction strip is embedded by double material injection molding process, which increases the friction resistance of the temperature sensing probe and avoids the wear caused by the direct contact of hard rubber, and the reliability of long-term use is significantly improved.

[0023] As a further aspect of the utility model, the end of the semicircular clamping piece is provided with a backward bending lead-in end, and the second guide gap is formed between the two lead-in ends, so that the temperature sensing probe can be smoothly embedded into the annular limiting space during production and assembly.

[0024] As a further aspect of the utility model, a space is provided below the limiting clamping tongue, which can bend downward after the limiting clamping tongue is pressed, so that the temperature sensing probe passes through the first guide gap. The space provided below the limiting clamping tongue provides space for the pressure bending of the limiting clamping tongue, further enhances the assembly fault tolerance, and even if the probe has a slight size deviation, it can still be smoothly embedded without damaging the structure.

[0025] As a preferred aspect of the utility model, the limiting part is an elastic strip made of soft rubber material and having an upwardly arched arc segment, and the elastic strip is integrally formed with the corresponding heat dissipation groove hole grid by double material injection molding, wherein the inner surface of the arc segment and the inner wall of the positioning groove jointly define a constraint channel with a diameter smaller than the outer diameter of the temperature sensing probe, and when the temperature sensing probe is inserted, the elastic strip is stretched and tightly attached to the outer wall of the temperature sensing probe, forming a radial clamping force.

[0026] As a further aspect of the utility model, the positioning grooves are arranged on the grid of the heat dissipation groove hole, and the elastic strip is arranged on the heat dissipation groove hole grid between adjacent positioning grooves.

[0027] The above-mentioned scheme replaces the limiting clamping tongue or the positioning clamping part with a soft rubber elastic strip, which is integrally formed with the heat dissipation groove hole grid by double material injection molding process. This scheme further optimizes the cost and performance balance - the arched arc segment of the elastic strip and the positioning groove form a constraint channel with a diameter slightly smaller than the probe, and the radial clamping force is generated when the probe is inserted to stretch the strip, the high elasticity and wear resistance of the soft rubber material ensure that the stable clamping force can be maintained after repeated insertion and removal, completely avoiding the failure risk caused by thermal expansion and cold contraction of the adhesive method; at the same time, the elastic strip does not need complex moving parts, and the mold structure is further simplified, and only the injection molding material needs to be adjusted to realize the function, which significantly reduces the production complexity.

[0028] As a further aspect of the present application, the arch height of the elastic strip is one-third to one-half of the outer diameter of the temperature sensing probe, and a reinforcing rib is arranged at the connection between the end of the elastic strip and the corresponding heat dissipation groove grid, so that the fatigue resistance of the elastic strip under long-term stress is ensured, and deformation or breakage is avoided.

[0029] In summary, the present application has the following advantages over the prior art: Firstly, the present application innovatively adopts an integrated injection molding method of positioning groove and heat dissipation groove hole, completely abandoning the traditional clamp and the complex mold required therefor. This scheme not only greatly simplifies the mold development process and effectively reduces the production cost, but also comprehensively optimizes the fixing method of the temperature sensing probe of the refrigeration box at the structural design level. On the one hand, it successfully retains the original heat dissipation function of the heat dissipation back plate, ensuring the normal operation of the refrigeration box; on the other hand, it cleverly realizes the rapid positioning of the temperature sensing probe through a physical limiting channel, making the probe installation more convenient and efficient.

[0030] Secondly, the present application utilizes the guiding gap of the limiting clamping tongue piece to guide the temperature sensing probe to quickly realize centering and smoothly press in. At the same time, in cooperation with the clamping piece of the positioning clamp, a multi-stage limiting channel is formed. It not only avoids the tedious operation of precise alignment of screw holes in the traditional method and reduces various problems that may be caused by alignment deviation; but also fundamentally avoids the failure risk caused by the thermal expansion and cold contraction effect of adhesive fixing, ensuring that the temperature sensing probe can maintain a stable and reliable fixed state in various complex environments.

[0031] In addition, the present application also provides a scheme of replacing the limiting clamping tongue piece or the positioning clamp with an elastic strip made of soft glue. This scheme adopts a double-material injection molding technology to perfectly and seamlessly combine the soft glue elastic part with the hard glue heat dissipation back plate. The flexibility of the soft glue material can give the temperature sensing probe an adaptive clamping force when it is inserted, ensuring the firmness of the temperature sensing probe installation. Moreover, through the reinforcing rib at the connecting end of the elastic strip, the fatigue resistance and wear resistance of the elastic strip during long-term use are effectively improved, further enhancing the stability and durability of the entire simple assembly structure.

[0032] In summary, the present application successfully solves a series of core problems in the traditional technology, such as additional fastening parts, high mold cost, low assembly efficiency, and loose fixing, through the deep optimization and improvement of the temperature sensing simple assembly structure, and finally realizes the ideal effect of low-cost investment, high-reliability operation, and easy operation and implementation.

The inner diameter of the positioning groove 3 is consistent with the outer diameter of a temperature sensing probe 8. A limiting component 4 is further arranged on the opening edge of the positioning groove 3 or the grid between adjacent positioning grooves 3.
