Description

Technical Field

[0001] The utility model belongs to the technical field of collection bags, and in particular relates to a birch sap collection bag and a collection needle. Background Art

[0002] Birch sap is a transparent, colorless or slightly yellowish sap secreted from the birch cambium. It contains ingredients such as betulin. Birch sap is collected using a special collection bag and a needle inserted into the birch tree.

[0003] At present, the collection bag is generally composed of a bag body and a connector, and the two are generally sealed at the connection point by hot melting. However, the hot melt connection is prone to local damage, which may cause subsequent leakage problems. Therefore, relying solely on a single hot melt seal cannot guarantee sealing. Therefore, there are limitations in actual use and there is room for improvement. Utility Model Content

When collecting birch sap, the sap is injected into the bag body through the connecting head; an alignment groove is provided at the opening area of the bag body, and the bottom of the connecting head is placed in the alignment groove, and the two are hot-melt connected; a sealing component is also provided on the bag body, which includes a covering part, one end of which is integrally provided on the bag body, and the other end is a free end and extends toward the direction of the connecting head; a limiting part is fixedly engaged with the connecting head, and the bottom of the limiting part is against the covering part, so as to realize the installation connection of the covering part. At this time, the connection area between the connecting head and the alignment groove can be covered, thereby forming a sealing area to avoid leakage problems in the later stage.

[0006] Preferably, a mounting ring groove is provided on the bottom surface of the connector, the covering member is an annular plate, one end of the annular plate extends into the mounting ring groove, and the limiting member is inserted into the mounting ring groove and abuts against the annular plate to achieve limiting and tightening of the annular plate.

[0007] Preferably, the limiting member includes a clamping ring, which is sleeved on the middle area of the connector, and the bottom end surface of the clamping ring abuts against the top surface of the annular sheet, so that the annular sheet is limited by pressing.

[0008] Preferably, a connecting ring groove is formed on the bottom end surface of the tightening ring, and a convex ring is fixed at the bottom of the mounting ring groove, and the convex ring is snapped into the connecting ring groove.

[0009] Preferably, the longitudinal section of the convex ring is an isosceles trapezoidal shape, so after the convex ring is inserted into the connecting ring groove, the connecting ring groove can be forced to deform, so that the two sides of the clamping ring are pressed against the inner wall of the installation ring groove to achieve stable installation; the inner width of the connecting ring groove is smaller than the maximum width of the convex ring, and the clamping ring is made of rubber and can be deformed when under pressure.

[0010] The utility model also discloses a birch sap collecting needle, which is installed on a collecting bag. The collecting needle includes a needle body, the bottom of which passes through a connector to the inside of the bag body, and the top of which is inserted into the inside of the birch tree and transmits the birch sap into the bag body to complete the collection.

[0011] Preferably, a mounting plate is fixed on the surface of the needle body, and the mounting plate contacts the top area of the connector. A ring is provided at the connection between the connector and the mounting plate, and the connection between the two is achieved through the ring. Pulling blocks are also fixed on both sides of the ring. Through the setting of the pulling blocks, the ring can be disassembled and assembled more conveniently.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Through the designed sealing component, a sealing area can be formed again outside the hot melt area, thereby improving the sealing effect. Even if the hot melt area is damaged, it can ensure that the collected birch sap will not leak, thereby improving the shortcomings of the existing structure in use. At the same time, the sealing component has a simple structure, is easy to install, is very easy to operate, and has high overall practicality. BRIEF DESCRIPTION OF THE DRAWINGS
