Description

Technical Field

[0001] This utility model relates to the field of convenience cabinet technology, and in particular to a single-door convenience cabinet. Background Technology

[0002] Refrigerated convenience cabinets are a common type of commercial refrigeration equipment, widely used in convenience stores, supermarkets, and other places. They have a precise temperature control system that ensures the temperature inside the cabinet is maintained within a suitable refrigeration range, effectively extending the shelf life of food, beverages, and other goods.

[0003] Currently, most convenience lockers on the market are equipped with casters at the bottom for easy movement. However, these casters are usually located at the four corners of the bottom of the locker and lack an effective linkage mechanism. When the locker needs to be stopped, staff have to brake each of the four casters individually, which is a cumbersome process and significantly reduces the overall convenience of moving and stopping the locker. Summary of the Invention

[0004] This utility model relates to a single-door convenience cabinet, which integrates the braking action of four moving wheels through structural design. When braking the cabinet, simply rotating the transmission screw can simultaneously brake multiple moving wheels. Compared to manually braking multiple moving wheels one by one, this is more time-saving and labor-saving, improving the convenience of the cabinet. This cabinet retains the individual braking function of the moving wheels and adds the function of simultaneous braking of multiple moving wheels, allowing the cabinet to meet the different usage needs of users according to actual conditions.

[0005] In a first aspect, this utility model provides a single-door convenience cabinet, specifically comprising: a cabinet body having upper and lower sides; an upper section of the cabinet body being a refrigerated area; a lower section of the cabinet body being a frozen area; a guide groove centrally located at the bottom of the cabinet body; a guide slider slidably mounted inside the guide groove; a push-pull protrusion fixedly mounted at the bottom end of the guide slider; a transmission screw rotatably mounted at the bottom of the cabinet body; fixed bases fixedly mounted at the four corners of the bottom of the cabinet body; rotating wheels rotatably mounted at the bottom of the fixed bases; a transmission slide plate slidably mounted on the fixed bases; a friction protrusion fixedly mounted at the bottom outer end of the transmission slide plate; a connecting plate fixedly mounted between two transmission slide plates; a force-bearing protrusion fixedly mounted at the top of the connecting plate; and a disc-shaped retaining plate.

[0006] Furthermore, a restoring spring is embedded in the top of the mounting plate; the other end of the restoring spring is embedded in the bottom of the fixed base; a refrigeration door is installed at the opening of the refrigeration area of ​​the convenience cabinet; and a freezer door is installed at the opening of the freezer area of ​​the convenience cabinet.

[0007] Furthermore, the top of the force-bearing protrusion has an inclined structure; the inclined surface of the pushing protrusion is attached to the inclined surface of the force-bearing protrusion; and the bottom of the pushing protrusion has an inclined structure.

[0008] Furthermore, when the transmission screw rotates, it moves backward along with the guide slider and the pusher protrusion under the action of the threads; the transmission screw is also connected to the guide slider through the threads.

[0009] Furthermore, when the pushing protrusion moves backward, the inclined surface of the pushing protrusion will push against the inclined surface of the force-bearing protrusion; a control handwheel is fixedly installed at the front end of the transmission screw.

[0010] Furthermore, after being pushed, the inclined surface of the force-bearing protrusion will move downward along with the connecting plate and the transmission slide plate; an embedded baffle is fixedly installed on the outer circumference of the friction protrusion.

[0011] Furthermore, when the transmission slide plate moves downward, the friction protrusion will descend and contact the wheel wall of the moving wheel.

[0012] This utility model provides a single-door convenience cabinet, which has the following beneficial effects:

[0013] 1. This convenience locker integrates the braking operation of the four moving wheels into one unit. The operator only needs to rotate the transmission screw to simultaneously trigger the braking mechanism of multiple moving wheels. Compared with the traditional manual braking method, this design saves a lot of time and effort and significantly improves the ease of use of the convenience locker.

[0014] 2. This convenience cabinet not only retains the original individual braking function of the wheels, but also adds a synchronous braking function. This design allows the convenience cabinet to flexibly switch braking modes according to the actual needs of different usage scenarios. Whether it is necessary to quickly fix the position or to precisely control a single wheel, it can easily cope with the situation, greatly improving the flexibility and convenience of use.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please refer to Figures 1 to 5 Example 1:

[0027] This utility model proposes a single-door convenience cabinet, comprising: a cabinet body 1, which has upper and lower sides; the upper area of ​​the cabinet body 1 is a refrigeration area; the lower area of ​​the cabinet body 1 is a freezer area; a guide groove 4 is provided at the center of the bottom of the cabinet body 1; a guide slider 5 is slidably installed inside the guide groove 4; a pusher protrusion 6 is fixedly installed at the bottom end of the guide slider 5; a transmission screw 7 is rotatably installed at the bottom of the cabinet body 1; fixed bases 9 are fixedly installed at the four corners of the bottom of the cabinet body 1; and casters 10 are rotatably installed at the bottom of the fixed bases 9; the fixed bases 9 slide upwards... The device is equipped with a transmission slide plate 11; a friction protrusion 12 is fixedly installed at the bottom outer end of the transmission slide plate 11; a connecting plate 15 is fixedly installed between the two transmission slide plates 11; a force-bearing protrusion 16 is fixedly installed on the top of the connecting plate 15; the embedded baffle 13 is a disc-shaped structure, which combines the braking action of the four moving wheels 10 into one through structural design. When braking the convenience cabinet, only the transmission screw 7 needs to be rotated to simultaneously brake multiple moving wheels 10. Compared with manually braking multiple moving wheels 10 one by one, it is more time-saving and labor-saving, and improves the convenience of using the convenience cabinet.

[0028] In Example 2, based on Example 1, one end of a restoring spring 14 is embedded in the top of the mounting plate 13; the other end of the restoring spring 14 is embedded in the bottom of the fixed base 9; a refrigerator door 2 is installed at the opening of the refrigerator area of ​​the convenience cabinet 1; a freezer door 3 is installed at the opening of the freezer area of ​​the convenience cabinet 1; the top of the force-bearing protrusion 16 has an inclined structure; the inclined surface of the pushing protrusion 6 is attached to the inclined surface of the force-bearing protrusion 16; the bottom end of the pushing protrusion 6 has an inclined structure. This convenience cabinet retains the existing individual braking function of the moving wheels 10 by setting the moving wheels 10, and adds the function of multiple moving wheels 10 braking simultaneously, so that this convenience cabinet can meet the different usage needs of users according to the actual situation.

[0029] In Example 3, based on Example 2, when the transmission screw 7 rotates, it moves backward along with the guide slider 5 and the pushing protrusion 6 under the action of the threads. The transmission screw 7 is also connected to the guide slider 5 through the threads. When the pushing protrusion 6 moves backward, its inclined surface pushes against the inclined surface of the force-bearing protrusion 16. A control handwheel 8 is fixedly installed at the front end of the transmission screw 7. After being pushed, the inclined surface of the force-bearing protrusion 16 moves downward along with the connecting plate 15 and the transmission slide plate 11. An embedded baffle 13 is fixedly installed on the outer circumference of the friction protrusion 12. The transmission slide plate 11 moves downward along with the connecting plate 15 and the transmission slide plate 11. When moving downwards, the friction protrusion 12 descends and contacts the wheel wall of the moving wheel 10. By manually rotating the control handwheel 8, the control handwheel 8 drives the transmission screw 7 to rotate, causing the transmission screw 7 to move backwards along with the guide slider 5 and the push protrusion 6. During the movement, the inclined surface of the push protrusion 6 pushes against the inclined surface of the force-bearing protrusion 16, causing it to move downwards along with the connecting plate 15, the transmission slide plate 11, and the friction protrusion 12. The friction protrusion 12 then contacts the wheel wall of the moving wheel 10 as it moves downwards, thus stopping the moving wheel 10 and completing the positioning of the convenience cabinet 1.

[0030] Working principle: During use, the items can be refrigerated through the upper refrigeration area of ​​the convenience cabinet 1, and frozen through the lower freezing area. When it is necessary to stop the convenience cabinet 1, the handwheel 8 is manually rotated, which rotates the transmission screw 7. The transmission screw 7 rotates and moves the guide slider 5 and the push protrusion 6 backward. During the movement, the inclined surface of the push protrusion 6 pushes the inclined surface of the force-bearing protrusion 16, causing the connecting plate 15, the transmission slide plate 11, and the friction protrusion 12 to move downward. The friction protrusion 12 contacts the wheel wall of the moving wheel 10 as it moves downward, thus stopping the moving wheel 10 and completing the positioning of the convenience cabinet 1.
