In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0030] In this paper, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, and it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0031] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0032] Embodiment, refer to Figures 1-5For the first embodiment of the utility model, propose a big span both sides slide open and close heat preservation cabin cover and its transmission support mechanism for setting between cabin body 12 and cabin cover 13, the number of cabin cover 13 is two, and along the width direction of cabin body 12 arrangement, including gear 1, rack 2, sliding drive mechanism 3, gear 1 is used to rotate setting inside cabin body 12, the axis of gear 1 is along the length direction of cabin body 12 setting, the number of gear 1 is multiple, all gear 1 along the length direction of cabin body 12 arrangement;Rack 2 is used to set at the bottom surface of cabin cover 13, the length direction of rack 2 is along the width direction of cabin cover 13 setting, rack 2 is engaged with the gear 1 below it;The fixed end of sliding drive mechanism 3 is used to set inside cabin body 12, the output shaft of sliding drive mechanism 3 is transmission connection with gear 1, after the output shaft of sliding drive mechanism 3 drives gear 1 to rotate, rack 2 is used to drive cabin cover 13 to slide along the width direction of cabin body 12.

[0033] In the embodiment, the left and right two cabin covers 13 are all heat preservation boards, which have excellent heat preservation performance, high strength and stiffness, and light weight. The right upper end of the left cabin cover 13 has a protrusion. When the left and right two cabin covers 13 are spliced together, the protrusion on the left cabin cover 13 is placed on the right cabin cover 13. This stepped matching structure can better ensure the heat preservation and sealing performance of the heat preservation cabin.

[0034] When the output shaft of the sliding drive mechanism 3 rotates, it drives the gear 1 to rotate. Since the rack 2 and the gear 1 are engaged with each other, the rotational motion of the gear 1 is converted into the linear motion of the rack 2. The rack 2 drives the cabin cover 13 to slide along the width direction of the cabin body 12. When the two cabin covers 13 are close to each other, the cabin body 12 is closed. When the two cabin covers 13 are away from each other, the cabin body 12 is opened. When the sliding drive mechanism 3 stops working, the gear 1 stops rotating, and the rack 2 and the cabin cover 13 stay in the current position without moving. This can realize reliable locking of the cabin cover 13 without the need for additional cabin cover 13 locks. The cabin body 12 is closed and locked reliably, which can better ensure the heat preservation and sealing performance of the heat preservation cabin.

[0035] Through the cooperation of the multiple gears 1 and racks 2 arranged along the length direction of the cabin body 12, the cabin cover 13 can slide along the width direction of the cabin body 12. This can maximize the opening of the cabin cover 13, provide more convenient operation space, and facilitate the loading and unloading of goods. The cooperation of the multiple gears 1 and racks 2 can effectively distribute the stress of the cabin cover 13, thereby realizing the overall movement of the large-span cabin cover 13. Since the cabin cover 13 is opened by sliding rather than rotating, the height of the entire heat preservation cabin will not increase during the opening process. Compared with the cabin cover 13 opened by a complex linkage mechanism, the utility model does not occupy the space inside the cabin body 12 after being opened, which can more effectively utilize the space inside the cabin body 12, improve the utilization rate of the internal space of the heat preservation cabin, and facilitate the arrangement and operation of equipment.

[0036] Compared with some hatch covers 13 using complex connecting mechanisms or other complex transmission structures, the gear 1 and the rack 2 transmission adopted by the utility model is relatively simple, and many unnecessary parts and complex connection structures can be reduced. This not only can reduce the manufacturing cost, but also can improve the reliability and stability of the system, reduce the failure risk caused by the complex structure, and facilitate daily maintenance and maintenance.

[0037] During the opening and closing process of the hatch cover 13, through the meshing transmission of the plurality of gears 1 and the racks 2, the stress of the hatch cover 13 can be more evenly distributed on each gear 1 and rack 2, so that the hatch cover 13 will not bear a large concentrated force in some parts, the strength and stiffness requirements of the hatch cover 13 can be reduced, and the lightweight design of the hatch cover 13 and the reduction of manufacturing cost are facilitated.

[0038] Further, as shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , it further comprises a support seat 4, the support seat 4 is arranged on the inner wall of the cabin body 12, the fixed end of the sliding drive mechanism 3 is arranged on the support seat 4, and the gear 1 is rotatably arranged on the support seat 4. The support seat 4 can provide a stable mounting position for the gear 1 and the sliding drive mechanism 3, and the gear 1 and the sliding drive mechanism 3 are both mounted on the support seat 4. When mounting, only the support seat 4 and the cabin body 12 need to be connected together, and disassembly is more simple and convenient.

[0039] Further, as shown in Figure 1 , the support seat 4 is arranged in one-to-one correspondence with the gear 1, so that each gear 1 has an independent support, the transmission accuracy and stability can be improved, and the space occupied by the support seat 4 inside the cabin body 12 can be reduced, and the utilization rate of the internal space of the cabin body 12 can be improved.

[0040] Further, as shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , it further comprises a reinforcing beam 5, the reinforcing beam 5 is arranged on the inner wall of the cabin body 12, and the support seat 4 is arranged at the upper end of the reinforcing beam 5. The reinforcing beam 5 can not only enhance the structural strength of the cabin body 12, but also provide more stable support for the support seat 4, ensure the rigidity and strength of the support seat 4, and better ensure the stability of the overall structure. The outer side of the reinforcing beam 5 is fixed on the inner wall of the cabin body 12, and the lower end of the reinforcing beam 5 is fixed on the bottom plate of the cabin body 12, so that the connection is more firm and reliable. The support seat 4 and the reinforcing beam 5 cooperate to transfer the pressure of the hatch cover 13 to the cabin wall and the bottom wall of the cabin body 12, so that the stability of the overall structure can be more reliably ensured.

[0041] Further, as shown in Figure 3 andFigure 4 As shown, the support base 4 has a lower accommodating groove 6, a middle sliding groove 7 and an upper sliding groove 8, which are sequentially communicated from bottom to top, and the length of the upper sliding groove 8 along the length direction of the cabin body 12 is less than the length of the middle sliding groove 7 along the length direction of the cabin body 12. The gear 1 is rotationally arranged in the lower accommodating groove 6, the gear rack 2 is inserted into the middle sliding groove 7 and forms a sliding fit, and the connecting strip 9 is inserted into the upper sliding groove 8 and forms a sliding fit. The lower end of the connecting strip 9 is connected with the gear rack 2, and the upper end of the connecting strip 9 is arranged on the hatch cover 13. The lower accommodating groove 6 provides a mounting space for the gear 1, so that the gear 1 can stably rotate. The middle sliding groove 7 and the upper sliding groove 8 respectively provide a guiding effect for the gear rack 2 and the connecting strip 9. The connecting strip 9 connects the gear rack 2 and the hatch cover 13, so that the rotation of the gear 1 can drive the sliding of the hatch cover 13, and at the same time, the stability of the hatch cover 13 during sliding is ensured, and the deviation of the hatch cover 13 is prevented.

[0042] Further, as shown in Figure 1 , Figure 3 and Figure 4 , the positioning strip 10 is further included, the upper end of the positioning strip 10 is arranged on the hatch cover 13, the lower end of the positioning strip 10 is connected with the upper end of the connecting strip 9, and the lower end surface of the positioning strip 10 is overlapped with the upper end surface of the support base 4. During the sliding of the hatch cover 13, the positioning strip 10 slides along the upper end surface of the support base 4, which can further position and stabilize the hatch cover 13. In cooperation with the connecting strip 9, the shaking or deviation of the hatch cover 13 during sliding can be prevented, and the closing accuracy of the hatch cover 13 is improved.

[0043] Further, as shown in Figure 4 , the width of the gear rack 2 is greater than the thickness of the gear 1, so that the contact area between the gear rack 2 and the gear 1 can be increased, thereby increasing the force receiving area of the gear 1 and improving the efficiency and stability of the transmission. At the same time, the gear rack 2 with a larger width can better bear the weight and external force of the hatch cover 13, and the risk of deformation is reduced.

[0044] Further, as shown in Figure 1 and Figure 2As shown, the telescopic support rods 11 have upper ends for being hingedly connected with the hatch covers 13 and lower ends for being hingedly connected with the outer wall of the cabin body 12, and the axes of the hinged joints are in the same direction as the length direction of the cabin body 12. Taking the case where the length direction of the cabin body 12 and the hatch covers 13 is arranged in the front-rear direction as an example, the two hatch covers 13 on the left and right can slide in the left-right direction above the cabin body 12, and four telescopic support rods 11 are hingedly connected with the cabin body 12 in the front-rear direction on the left and right sides of the cabin body 12, and the axes of the upper and lower hinged joints of each telescopic support rod 11 are arranged in the front-rear direction, so that the telescopic support rods 11 can flexibly rotate with the sliding of the hatch covers 13 and adapt to different opening angles. During the opening and closing of the hatch covers 13, the telescopic support rods 11 play an auxiliary supporting role, can share the weight of the hatch covers 13, and reduce the burden of the gear 1 and the rack 2.

[0045] Further, the upper ends of the telescopic support rods 11 are detachably connected with the hatch covers 13, and the lower ends of the telescopic support rods 11 are detachably connected with the cabin body 12. The detachable connection facilitates the installation, disassembly and maintenance of the telescopic support rods 11, and the telescopic support rods 11 can be detached when not needed, without affecting the normal use of the heat preservation cabin.

[0046] Further, the sliding drive mechanism 3 is a reduction motor, which is a combination of a servo motor and a reducer, ensures synchronous operation of all actions and will not cause damage to the remaining structure due to pulling, and through the reducer, the weak brake torque of the servo motor is changed into a larger hatch cover 13 locking force, which can better ensure the sealing effect of the cabin body 12. The reduction motor is not only a power provider, but also a locking device for the hatch covers 13.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
