Fig. 1-2 are schematic structural views of a ram assembly 100 disclosed in this embodiment. The ram assembly 100 includes a housing 110 and a ram 120, the housing 110 having a cavity 111 extending in an axial direction of the housing 110. The inner surface of the cavity 111 is provided with a guide groove 113 along the axial direction of the cavity 111, and the side edge of the guide groove 113 is provided with a plurality of spacing grooves 112 communicated with the guide groove 113 at intervals. The ram 120 has a first end and a second end that extend axially. The first end of the top bar 120 is arranged in the cavity 111, and the second end of the top bar 120 extends out of the cavity 111. The first end of the top rod 120 is provided with a limiting block 121, the limiting block 121 is slidably disposed in the guide groove 113, and the limiting block 121 can enter the limiting groove 112 to limit the movement of the top rod 120.

The ejector rod assembly 100 adjusts the extension length of the ejector rod 120 through the axial movement of the ejector rod 120 in the cavity 111 of the housing 110, and after the extension length of the ejector rod 120 is adjusted, the ejector rod 120 is rotated to enable the limiting block 121 to enter the limiting groove 112 to limit the axial movement of the ejector rod 120, so that the occurrence of the condition that the ejector rod 120 axially moves to cause failure in the use process of the ejector rod assembly 100 is avoided.

In the present embodiment, as shown in fig. 1, the stopper groove 112 has an opening portion 1121 and a stopper portion 1122, the opening portion 1121 communicates with the guide groove 113, and the stopper portion 1122 extends from one end of the opening portion 1121 away from the guide groove 113 in a direction opposite to the sliding-out direction of the push rod 120. The opening portion 1121 and the stopper portion 1122 form an L-shaped structure.

In the scheme of this embodiment, the stopper 1122 is disposed on the limiting groove 112, so that the occurrence of the situation that the push rod 120 axially moves due to the fact that the push rod 120 rotates to slide the limiting block 121 out of the limiting groove 112 in the use process of the push rod assembly 100 can be avoided.

By adopting the structure, the movement of the ejector rod 120 can be more intuitively adjusted, and the processing is also convenient.

In other embodiments, one of the guide groove 113 and the stopper groove 112 penetrates the outer surface of the housing 110 in a radial direction of the cavity 111. Alternatively, neither the guide groove 113 nor the stopper groove 112 penetrates the outer surface of the housing 110.

In the present embodiment, as shown in fig. 1 and 2, the plurality of limiting grooves 112 are disposed at intervals on both sides of the guide groove 113, and the openings of two adjacent limiting grooves 112 located on both sides of the guide groove 113 are disposed in a staggered manner.

The limiting groove 112 is formed in the structure, and compared with the single-side limiting groove 112, the adjusting gear of the ejector rod 120 can be increased, so that the ejector rod assembly 100 has more choices of adjustable length.

Of course, in other embodiments, the limiting groove 112 may be disposed on one side of the guide groove 113.

The housing 110 is provided with a mounting portion, and the mounting portion is arranged at one end of the housing 110 close to the second end of the push rod 120. By adopting the structure, the mounting part of the push rod assembly 100 is arranged at one end of the shell 110 close to the second end of the push rod 120, so that the influence of the length of the shell 110 on the adjustable length of the push rod 120 is avoided when the push rod assembly is used.

In this embodiment, as shown in fig. 1 and 2, the mounting portion includes a limiting portion 114 and a clamping portion 115 protruding outward from the outer surface of the housing 110 and disposed at an interval, a mounting groove 116 is formed between the limiting portion 114 and the clamping portion 115, and the clamping portion 115 has a plane disposed obliquely from one end far away from the mounting groove 116 to one end close to the mounting groove 116. When installing ejector pin subassembly 100, insert the mounting hole of adaptation with casing 110 near the one end of joint portion 115 least significant end, the mounting hole removes along the slope plane of joint portion 115, and at this in-process, elastic deformation can take place for the inner wall of joint portion 115 or mounting hole makes the terminal surface entering and the joint of mounting hole both sides in mounting groove 116. The installation department adopts above-mentioned structural style, and simple to operate is quick.

In other embodiments, the mounting portion and the mounting hole may be fixed by detachably and separately installing both sides of the mounting groove 116 of the mounting portion, inserting one side of the mounting portion into the mounting hole, and then fixing the other side of the mounting portion.

In the present embodiment, as shown in fig. 1 and 2, the push rod assembly 100 further includes a knob 140, and the knob 140 is disposed at the second end of the push rod 120. The knob 140 is convenient for the operator to operate, and the knob 140 can increase the force bearing area of the end of the top bar 120. The peripheral surface of the knob 140 is provided with raised lines to enhance friction and hand feel.

As further shown in fig. 1 and 2, the stem assembly 100 further includes a cover 150, and the cover 150 is detachably mounted on an end of the housing 110 away from the second end of the stem 120. A removable cover 150 is provided to facilitate the processing and installation of the components inside the housing 110.

As shown in fig. 3 to 7, the present embodiment further provides a kitchen range chassis, which includes a chassis body 200 and the above-mentioned top bar assembly 100. The cooker chassis adopts the structure, the ejector rod assembly 100 is arranged on the outer side face of the chassis body 200, so that when the cooker chassis is installed on the cooking bench 300, the end part of the ejector rod 120 can be abutted against the side wall of the cooking bench opening 301 as far as possible by adjusting the extending length of the ejector rod 120 of the ejector rod assembly 100, and the phenomenon that the cooker chassis moves greatly in the using process due to the large gap existing between the side wall of the cooker chassis and the side wall of the cooking bench opening 301 is avoided.
