Description

Technical Field

[0001] The utility model relates to the field of clean purification, in particular to a self-locking structure of a transfer cabin docking vehicle. Background Art

[0002] The transfer cabin is a main equipment used for transferring items across rooms in the clean purification field. When there are many items to be transferred or the transfer cabin is large, they are generally transferred using a transfer inner cart with wheels. When placing items, pull the transfer inner cart out of the cabin, and after placing the items, push them into the cabin. After self-cleaning, disinfection or sterilization processes, pull out the transfer inner cart on the other side of the cabin to take out the items. A transfer track corresponding to the wheels of the transfer inner cart is generally provided in the cabin. The track can be docked with the track of the transfer outer cart to ensure that the transfer inner cart enters and exits the cabin on a fixed track. However, in order to ensure the stability of the transfer inner cart on the transfer outer cart and cabin tracks, a limiting mechanism is often used to ensure that the transfer inner cart does not derail.

[0003] The current limit mechanism generally adopts the form of positioning pins, that is, a positioning hole is opened on the track, and when the transfer inner car reaches the specified position, the positioning pin is inserted to ensure the stability of the transfer inner car. Although this form of positioning has a simple production process, the following problems are prone to occur during actual use:

[0004] (1) The positioning pin needs to be taken and put back every time it is operated, which is inconvenient to operate and may easily cause the positioning pin to be lost during use.

[0005] (2) The positioning hole will form a sanitary dead corner, which is inconvenient to clean. The dirt accumulated over a long period of time may even make it difficult to place the positioning pin in the positioning hole. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a self-locking structure of a transfer compartment docking vehicle to solve one or more problems in the prior art.

[0007] To achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A self-locking structure for a transfer compartment docking vehicle, the self-locking structure comprising a carrier and a locking assembly, a track is arranged on the surface of the carrier, a part of the locking assembly is fixedly connected to the surface of the carrier, and the locking or release of the locking assembly is achieved by docking or separation of two self-locking structures.

[0009] Furthermore, the locking assembly includes a self-locking member, the self-locking member is bent, a portion of the self-locking member extends above the track, and a gap is left between the self-locking member and a side edge of the carrier.

[0010] Furthermore, the locking assembly includes a fixing hole plate, and the fixing hole plate is fixed to a surface of the carrier away from the track.

[0011] Furthermore, the fixed hole plate is provided with a first hole, and the locking assembly further comprises a moving rod, and the moving rod cooperates with the first hole to move relative to the fixed hole plate.

[0012] Furthermore, one end of the movement rod is fixedly connected to the self-locking member, and the other end of the movement rod is connected to a limit block.

[0013] Furthermore, the locking assembly includes an elastic member, one end of the elastic member is fixedly connected to the self-locking member, and the other end of the elastic member is fixedly connected to the fixed hole plate and close to the surface of the self-locking member.

[0014] Furthermore, the locking assembly also includes a pushing member, which is fixed to the end of the carrier and cooperates with the carrier and a part of the self-locking member.

[0015] Furthermore, the pushing member is fan-shaped or cone-shaped.

[0016] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0017] The locking assembly solves the problem of manual limit when the inner transfer vehicle enters and exits the cabin. When the inner transfer vehicle needs to be transferred from the cabin to the outer transfer vehicle or pushed into the cabin by the outer transfer vehicle, the lock can be unlocked by simply docking the outer transfer vehicle with the track inside the cabin. This reduces the labor cost during the transfer process and reduces the sanitary dead corner problem caused by the positioning pins and the problem that the positioning pins are easily lost during long-term use.

[0027] The following describes a specific structure of the self-locking structure of the transfer cabin docking vehicle:

[0028] See also Figures 1 to 6 The self-locking structure of the transfer compartment docking vehicle of this embodiment includes a carrier 1 and a locking assembly 2. A track 101 is set on the upper surface of the carrier 1, and the track 101 is used for the movement of the vehicle.

[0029] Furthermore, the locking assembly 2 includes a self-locking member 201, and the self-locking member 201 is bent. Preferably, the self-locking member 201 in this embodiment is "L"-shaped, and a portion of the self-locking member 201 extends above the track 101. When the self-locking member 201 is in an undocked state, there is a gap between it and the side of the carrier 1.

[0030] Furthermore, the locking assembly 2 includes a fixing hole plate 202 , which is fixed to the lower surface of the carrier 1 and close to the long side of the self-locking member 201 . The fixing hole plate 202 defines a first hole 2021 .

[0031] Furthermore, the locking assembly 2 also includes a moving rod 203, which is arranged below the carrier 1, one end of the moving rod 203 is fixed to the self-locking part 201, and the other end of the moving rod 203 is connected to the limit block 206, and the moving rod 203 passes through the first hole 2021 and moves relative to the fixed hole plate 202.

[0032] Furthermore, the locking assembly 2 includes an elastic member 204, one end of the elastic member 204 is fixed to the self-locking member 201, and the other end of the elastic member 204 is fixed to the fixed hole plate 202 and close to the surface of the self-locking member 201, and the elastic member 204 is concentrically arranged with the first hole 2021. Preferably, the elastic member 204 described in this embodiment is a spring, and the inner diameter of the spring is larger than the inner diameter of the first hole 2021. The above-mentioned moving rod 203 is arranged in the elastic member 204 at a section outside the carrier 1.

[0033] Furthermore, the cross-sectional area of ​​the limit block 206 is larger than the area of ​​the first hole 2021 to limit the moving range of the motion rod 203 .

[0034] Furthermore, the locking assembly 2 also includes a pushing member 205, which is fan-shaped or conical. The pushing member 205 is fixed to the docking end of the carrier 1 and is respectively arranged on both sides of the carrier 1 with the fixed hole plate 202. Preferably, in this embodiment, the pushing member 205 is fan-shaped and two pushing members 205 are arranged in an upper and lower position relationship. The pushing member 205 cooperates with the gap formed by the above-mentioned carrier 1 and the self-locking member 201, and the locking or release of the locking assembly 2 is achieved by docking or separation of the two self-locking structures.

[0035] The specific working process of the self-locking structure of a transfer compartment docking vehicle described in an embodiment of the utility model is described below:

[0036] Two self-locking structures are provided, one located on the inner transfer vehicle and the other located on the outer transfer vehicle. When the locking assembly 2 is in a natural state, the elastic member 204 is in a contracted state, at which time the self-locking member 201 extends above the track 101, and has a limiting function for the inner transfer vehicle. When the track 101 of the outer transfer vehicle is docked with the track 101 in the cabin, the pushing member 205 of the outer transfer vehicle pushes the self-locking member 201 fixed on the track 101 in the cabin to move outward, and the elastic member 204 is stretched until the two tracks 101 are completely docked, at which time the self-locking member 201 is disengaged from the track 101, and the inner transfer vehicle can be pushed in or out. After the transfer is completed, when the outer transfer vehicle is pulled, the two tracks 101 begin to disengage, at which time the self-locking member 201 automatically resets to a limited state under the action of the elastic member 204.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
